A concentration index, a standardised covariance between a health variable and relative income ranks, is often used to quantify income-related health inequalities. There is a lack of formal approach to study the effect of an exposure, e.g., education, on such measures of inequality. In this paper we contribute by filling this gap and developing the necessary theory and method. Thus, we define a counterfactual concentration index for different levels of an exposure. We give conditions for the identification of this complex estimand, and then deduce its efficient influence function. This allows us to propose estimators, which are regular asymptotic linear under certain conditions. In particular, we show that these estimators are $\sqrt{n}$-consistent and asymptotically normal, as well as locally efficient. The implementation of the estimators is based on the fit of several nuisance functions. The estimators proposed have rate robustness properties allowing for convergence rates slower than $\sqrt{n}$-rate for some of the nuisance function fits. The relevance of the asymptotic results for finite samples is studied with simulation experiments. We also present a case study of the effect of education on income-related health inequalities for a Swedish cohort.

Women, migrants and those in manual occupations face barriers in the labor market and are more vulnerable to unemployment, which in turn may impact mental health and contributes to inequalities. Previous research has not considered the intertwinement of multiple inequalities. This study examined intersectional inequalities (intersecting gender, social class, and migration status) in poor mental health and the mediation role of unemployment in the Spanish adult population, using the 2012 and 2017 cross-sectional Spanish National Health Surveys (n = 22,383, 18-64 years, response rates: 89.6 % and 74.0 %). Mental health was measured using the GHQ-12 and classified into good and poor. Unemployment was classified as employed or unemployed. Gender (men or women), social class (manual or non-manual) and migration status (born in Spain or migrant) were cross-classified in eight intersectional strata. Intersectional mediation analysis showed that, compared to non-manual native men, poorer mental health was found in women, migrants and manual occupations (total effect). Unemployment completely mediates mental health inequalities in strata of men with manual occupations but partially in strata of women. Moreover, mental health inequality was explained by both higher unemployment prevalence (pure indirect effect) and by greater vulnerability to unemployment (mediated interaction effect) among native men and women in manual occupations and immigrant women in non-manual occupations compared to non-manual native men. In conclusion, complex mental health inequalities seem to be underpinned by the dual processes of higher risks and worse consequences of unemployment. Health policies should target strata of manual occupations since they were more likely to be unemployed.

In 2010, Sweden implemented the Choice in Primary Health Care reform, allowing private healthcare providers to establish themselves at self-selected locations. While intended to improve efficiency and responsiveness through increased competition, concerns were also raised about its potential to reinforce inequities in healthcare access across different population groups. This study examines intersectional inequities in unmet healthcare needs (UHCN) in relation to the reform's implementation. Using data from the Health on Equal Terms survey (2007-2014, N = 69,644), we applied a decision tree-based analytical method (Model-Based Recursive Partitioning) combined with a post-hoc selection approach based on the Area Under the Receiver Operating Characteristic Curve to identify intersectional subgroups and assess reform-related effects. Although UHCN prevalence decreased by 11% after the reform, this overall improvement did not result in a narrowing of the equity gap across intersectional groups. Those born outside the Nordic countries, intersecting with low income, low education, and middle age, remained at the highest risk of experiencing UHCN both before (PR = 6.67, p < 0.001) and after (PR = 5.14, p < 0.001) the reform's implementation, indicating that, while absolute levels of UHCN decreased, the relative positioning of disadvantaged groups remained largely unchanged. These findings illustrate that overall improvements in healthcare access following market-oriented reforms do not necessarily address pre-existing structural inequities, and suggest that complementary equity-targeted measures will be required to ensure equitable access across diverse populations in Sweden. The decision tree-based approach proved valuable for evaluating health policies by uncovering heterogeneous effects across complex, intersectional patterns of healthcare outcomes.

Background Obesity is a global public health issue with increasing prevalence and notable differences across population. Previous studies on body mass index (BMI) trends and inequalities have focused on overweight/obesity prevalence or average BMI changes, overlooking differences across the BMI distribution. This study investigates whether changes in BMI distribution are uniform or different over time and educational attainment. Methods This study is based on repeated cross-sectional surveys in Västerbotten, Sweden. Study participants were expectant parents visiting antenatal care (2010-2019) as part of the Salut Programme. During early pregnancy, 18,215 women and 17,890 male partners completed questionnaires. Quantile regression analyses were conducted to assess BMI distribution changes over time and by education for men and women. Results The BMI distribution for women showed a sharper increase in the upper tail in 2018/19 compared to 2010/11, whereas for men, the upper tail showed a gradual rise over years. Similar changes in BMI distributions were observed over time across both educational groups, with a notable increase in the higher BMI segments. Conclusion The study revealed weight gain inequalities, with higher BMI segments experiencing a disproportionately higher rise compared to others. Identifying high-risk groups in vulnerable settings will better equip decision-makers to design and implement targeted intervention strategies to reduce overweight and obesity.

Primary health care (PHC) systems are a crucial instrument for achieving equitable population health, but there is little evidence of how PHC reforms impact equities in population health. In 2010, Sweden implemented a reform that promoted marketization and privatization of PHC. The present study uses a novel integration of intersectionality-informed and evaluative epidemiological analytical frameworks to disentangle the impact of the 2010 Swedish PHC reform on intersectional inequities in avoidable hospitalizations. The study population comprised the total Swedish population aged 18-85 years across 2001-2017, in total 129 million annual observations, for whom register data on sociodemographics and hospitalizations due to ambulatory care sensitive conditions were retrieved. Multilevel Analysis of Individual Heterogeneity and Discriminatory Analyses (MAIHDA) were run for the pre -reform (2001-2009) and post -reform (2010-2017) periods to provide a mapping of inequities. In addition, random effects estimates reflecting the discriminatory accuracy of intersectional strata were extracted from a series MAIHDAs run per year 2001-2017. The estimates were re-analyzed by Interrupted Time Series Analysis (ITSA), in order to identify the impact of the reform on measures of intersectional inequity in avoidable hospitalizations. The results point to a complex reconfiguration of social inequities following the reform. While the post -reform period showed a reduction in overall rates of avoidable hospitalizations and in age disparities, socioeconomic inequities in avoidable hospitalizations, as well as the importance of interactions between complex social positions, both increased. Socioeconomically disadvantaged groups born in the Nordic countries seem to have benefited the least from the reform. The study supports a greater attention to the potentially complex consequences that health reforms can have on inequities in health and health care, which may not be immediate apparent in conventional evaluations of either population-average outcomes, or by simple evaluations of equity impacts. Methodological approaches for evaluation of complex inequity impacts need further development.

Colorectal cancer (CRC) represents a significant health burden worldwide, with existing inequities in incidence and mortality. In Sweden, CRC screening programmes have varied regionally since the mid-2000s, but the significance of organised screening for counteracting complex inequities in screening attendance has not been investigated. This study aimed to assess patterns of inequities in lifetime CRC screening attendance in the Swedish population aged 60-69 years by identifying intersectional strata at higher risk of never attending CRC screening. The research question is answered using decision trees to reduce the complexity of a full intersectional matrix into a reduced intersectional matrix for risk estimation. Participants were drawn from the cross-sectional 2019 European Health Interview Survey (N=9,757, response rate: 32.52%). The Conditional Inference Tree (CIT) (AUC= 0.7489, F-score=0.7912, depth= 4, significance level=0.05) identified region of residence (opportunistic vs organised screening), country of origin, gender, age and income as relevant variables in explaining lifetime CRC screening attendance in Sweden. Then, Poisson regression with robust standard errors estimated that EU-born women living in opportunistic screening regions belonging to the 2nd income quintile had the highest risk of never attending CRC screening (PR=8.54, p<0.001), followed by EU-born men living in opportunistic screening regions (PR=7.41, p<0.001) compared to the reference category (i.e. people aged 65-69 living in organised screening regions). In contrast, only age-related differences in attendance were found in regions with organised screening (i.e. people aged 60-64 living in regions with organised screening (PR=2.01, p<0.05)). The AUC of the reduced intersectional matrix model (0.7489) was higher than the full intersectional matrix model (0.6959) and slightly higher than the main effects model (0.7483), demonstrating intersectional effects of the reduced intersectional matrix compared with the main effects model and better discriminatory accuracy than the full intersectional matrix. In conclusion, regions with long-established organised CRC screening programmes display more limited socio-demographic inequities than regions with opportunistic CRC screening. This suggests that organised screening may be a crucial policy instrument to improve equity in CRC screening, which, in the long run, has the potential to prevent inequities in colorectal cancer mortality. Moreover, decision trees appear to be valuable statistical tools for efficient data-driven simplification of the analytical and empirical complexity that epidemiological intersectional analysis conventionally entails.

Background Oral health in Sweden is good at the population level, but seemingly with persisting or increasing inequities over the last decades. In 2008, a major Swedish reform introduced universal partial subsidies to promote preventive care and reduce the treatment cost for patients with extensive care needs. This study aimed to apply an intersectional approach to assess the impact of the 2008 subsidization reform on inequities in self-rated oral health among adults in Sweden over the period 2004–2018. Methods Data from 14 national surveys conducted over 2004–2018 were divided into three study periods: pre-reform (2004–2007), early post-reform (2008–2012) and late post-reform (2013–2018). The final study population was 118,650 individuals aged 24–84 years. Inequities in self-rated oral health were examined by intersectional analysis of individual heterogeneity and discriminatory accuracy across 48 intersectional strata defined by gender, age, educational level, income, and immigrant status. Results Overall, the prevalence of poor self-rated oral health decreased gradually after the reform. Gender-, education- and income-related inequities increased after the reform, but no discernible change was seen for age- or immigration-related inequities. The majority of intersectional strata experienced patterns of persistently or delayed increased inequities following the reform. Conclusions Increased inequities in self-rated oral health were found in most intersectional strata following the reform, despite the seemingly positive oral health trends at the population level. Applying an intersectional approach might be particularly relevant for welfare states with overall good oral health outcomes but unsuccessful efforts to reduce inequities.

Objective To examine how the effect of disadvantaged socioeconomic circumstances on the risk of paediatric infections is mediated by pregnancy smoking, excess weight during pregnancy and breast feeding in children under 5 years of age. Design A population-level, retrospective cohort study. The Swedish Medical Birth Register was combined with the National Patient Register, the longitudinal integration database for health insurance and labour market studies, the Cause of Death Register and a local register held by the Child Health Care Unit in Uppsala Region. Setting Uppsala Region, Sweden. Patients 63 216 term and post-term singletons born to women who resided in Uppsala Region, Sweden between 1997 and 2015. Main outcome measures Number of hospital admissions for infectious diseases. Secondary outcomes were the number of hospitalisations for respiratory and enteric infections, respectively. Results The effect of disadvantaged socioeconomic circumstances, that is, low maternal education on the overall risk of paediatric infections was mediated to a considerable (33%–64%) proportion by pregnancy smoking, excess weight during pregnancy and breast feeding. Conclusions Pregnancy smoking, excess weight during pregnancy and breast feeding mediate a considerable proportion of the association between deprived socioeconomic circumstances and paediatric infectious diseases. Therefore, inequalities in paediatric infectious diseases may be reduced by public health policies addressing these health-related behaviours.

Body mass index (BMI) has increased in Sweden, disproportionally for socially disadvantaged groups, including women, low-educated, and immigrants, who may also face economic constraints, physical inactivity, and poor-quality diets. Intersectional public health research aims to unravel such complex social inequalities, but the intersectional transmission of inequalities to BMI remains unexplored. We aimed to examine intersectional inequalities in BMI mediated by economic strain and health-related lifestyle in the Swedish population. By using the Health on Equal Terms cross-sectional surveys in 2016, 2018, 2020, and 2021 (n = 44,177 inhabitants aged 25 and over), we performed an intersectional mediation analysis to analyze how inequalities across social intersectional strata (by gender, education, and migration status) may be transmitted through economic strain and unhealthy lifestyle (physical inactivity or inadequate fruit/vegetables consumption) to BMI. Our findings showed a sequential transmission that indicates the fact that socially disadvantaged strata (compared with high-educated native men) experienced more economic strain, which in turn led to poorer health-related lifestyles and ultimately to a higher BMI. We also found that certain intersectional strata, such as high-educated women, were more vulnerable to economic strain, despite having lower BMI than high-educated native men. Additionally, the highest BMI and unhealthy lifestyle risk was observed among low- and middle-educated men. In conclusion, not only inequalities in BMI, but also the economic and behavioral pathways underpinning the inequalities, act by intersectional patterns. Public health interventions should provide economic security, particularly for women and migrant population as well as promoting a healthy lifestyle in lower-educated strata, especially among men, to achieve healthy BMI levels.

Abstract Background The Swedish Primary Health Care (PHC) system has, like in other European countries, undergone a gradual transition towards marketization and privatization, most distinctly through a 2010 choice reform. The reform led to an overall but regionally heterogenous expansion of private PHC providers in Sweden, and with evidence also pointing to possible inequities in various aspects of PHC provision. Evidence on the reform’s impact on population-level primary health care performance and equity in performance remains scarce. The present study therefore aimed to examine whether the increase in private provision after the reform impacted on population-average rates of avoidable hospitalizations, as well as on corresponding socioeconomic inequities. Methods This register-based study used a multiple-group interrupted time-series design for the study period 2001–2017, with the study population (N = 51 million observations) randomly drawn from the total Swedish population aged 18–85 years. High, medium, and low implementing comparison groups were classified by tertiles of increase in private PHC providers after the reform. PHC performance was measured by avoidable hospitalizations, and socioeconomic position by education and income. Interrupted time series analysis based on individual-level data was used to estimate the reform impact on avoidable hospitalization risk, and on inequities through the Relative Index of Inequality (RII). Results All three comparisons groups displayed decreasing risk of avoidable hospitalizations but increasing socioeconomic inequities across the study period. Compared to regions with little change in provision after the reform, regions with large increase in private provision saw a steeper decrease in avoidable hospitalizations after the reform (relative risk (95%): 1.6% (1.1; 2.1)), but at the same time steeper increase in inequities (by education: 2.0% (0.1%; 4.0); by income: 2.2% (-0.1; 4.3)). Conclusions The study suggests that the increase in private health care centers, enabled by the choice reform, contributed to a small improvement when it comes to overall PHC performance, but simultaneously to increased socioeconomic inequities in PHC performance. This duality in the impact of the Swedish reform also reflects the arguments in the European health policy debate on patient choice PHC models, with hopes of improved performance but fears of increased inequities.

OBJECTIVES:Six million children were under-vaccinated in 2022. Our study aimed to 1) quantify the magnitude of under-vaccination variation between health facilities, 2) assess to which extent individual and health center level factors contributed to the variation, 3) identify individual and health facility factors associated with under-vaccination, and 4), explore rural vs. urban health facility variations. METHODS:We used data from 61,839 children from The Gambia national routine vaccination register. We cross tabulated under-vaccination status across study variables and fitted two-level random intercept multilevel logistic regression models to measure variance, contribution to the variance, and factors associated with the variance and under-vaccination. RESULTS:We found that 7% of the prevalence of under-vaccination was due to variation between health facilities. Thirty-seven percent of the variation was explained by individual and health center variables. The variables explained 36% of the variance in urban and 19% in rural areas. Children who were not vaccinated at 4 months or with delayed history, due for vaccination in the rainy season, and health facilities with very small or large population to health worker ratios had higher under-vaccination odds. CONCLUSION:Our study indicates that one of the pathways to improving vaccination coverage is addressing factors driving under-vaccination inequities between health facilities through urban-rural differentiated strategies.

BackgroundIt is well known that socially deprived children are more likely to be hospitalised for infections. Less is known about how different social disadvantages interact. Therefore, we examine intersectional inequalities in overall, upper respiratory, lower respiratory, enteric and genitourinary infections in the first 5 years of life.MethodsWe conducted a population-based retrospective cohort study of Swedish children born between 1998 and 2015. Inequalities were examined using analysis of individual heterogeneity and discriminatory accuracy as the analytical framework. A variable with 60 intersectional strata was created by combining information on maternal education, household income, sex/gender and maternal migration status. We estimated the incidence rates of infectious disease hospitalisation for each intersectional strata and the associations between intersectional strata and infectious disease hospitalisations using logistic regression models. We furthermore quantified the discriminatory ability of the intersectional strata with respect to infectious disease hospitalisation.ResultsThe study included 1785 588 children and 318 080 hospital admissions. The highest overall incidence of hospitalisations for infections was found in boys born to low-educated mothers who lived in families with the lowest household income. The overall incidence of infections was unrelated to household income in children born to highly educated mothers. The ability of the intersectional strata to discriminate between children with and without infections was poor.ConclusionWe found that inequalities in paediatric infectious diseases were shaped by the intersections of different social disadvantages. These inequalities should be addressed by public health policies that reach all children.

INTRODUCTION:Identifying actionable targets is crucial to improve overall and equity in vaccination coverage, and in line with the global Immunization Agenda 2030. Therefore, this study seeks to assess the prevalence of missed opportunities for simultaneous vaccination (MOSVs) and their impact on vaccination coverage and urban-rural inequity in The Gambia. METHODS:We used data of children aged 12-23 months from The Gambia 2019/2020 demographic and health survey (weighted n = 1355) with seen vaccination cards. We analyzed: the frequency of MOSVs; percentage point coverage reduction attributable to MOSVs for 18 vaccine doses and full basic vaccination; and MOSVs' contribution to urban-rural coverage inequity through Blinder-Oaxaca decomposition. RESULTS:Sixty percent of children experienced MOSVs, in both urban and rural areas, but urban MOSVs were more seldom corrected (35.9 % vs 45.3 %). All eighteen vaccine doses assessed could have achieved between one to eleven percentage points higher coverage if MOSVs had been avoided, with full basic vaccination gaining even more. While MOSV correction did not impact overall urban-rural coverage inequity, it did exacerbate (explained coefficient = -0.1007; P = 0.002) inequities among children who experienced MOSVs, explaining 95 % of the observed difference. CONCLUSION:Our study highlights the prevalence and negative impact of MOSVs on overall vaccination coverage. Although MOSVs did not contribute significantly to the total urban-rural inequity in coverage, they have detrimental effects on vaccination coverage and urban-rural inequity among children who had experienced MOSVs. Addressing MOSVs, can enhance coverage and reduce the risk of under-vaccination, aligning with global initiatives.

Abstract Background Despite decreasing mortality from cardiovascular disease (CVD), there are persistent inequities in mortality between socioeconomic groups. Primary preventative medications reduce mortality in CVD; thus, inequitable treatments will contribute to unequal outcomes. Physicians might contribute to inequality by prescribing preventative medication for CVD to themselves in a biased manner. Aim To determine whether primary medications for preventing CVD were prescribed inequitably between physicians and non-physicians. Design and setting This retrospective study retrieved registry data on prescribed medications for all physicians in Sweden aged 45–74 years, during 2013, and for reference non-physician individuals, matched by sex, age, residence, and level of education. The outcome was any medication for preventing CVD, received at least once during 2013. Method Age and the sex-specific prevalence of myocardial infarction (MI) among physicians and non-physicians were used as a proxy for the need for medication. Thereafter, to limit the analysis to preventative medication, we excluded individuals that were diagnosed with CVD or diabetes. To analyse differences in medication usage between physicians and matched non-physicians, we estimated odds ratios (ORs) with conditional logistic regression and adjusted for need and household income. Results MI prevalences were 5.7% for men and 2.3% for women, among physicians, and 5.4% for men and 1.8% for women, among non-physicians. We included 25,105 physicians and 44,366 non-physicians. The OR for physicians receiving any CVD preventative medication, compared to non-physicians, was 1.65 (95% confidence interval 1.59–1.72). Conclusion We found an inequity in prescribed preventative CVD medications, which favoured physicians over non-physicians. KEYPOINTS Groups with low socioeconomic status have lower rates of using medication that prevents cardiovascular disease, compared to groups with high socioeconomic status. Physicians are responsible for prescribing all medicines to prevent cardiovascular disease; thus, biased prescriptions could have effects on the equality of care in the population. Compared to individuals with equivalent education, physicians had higher rates of using medication that prevents cardiovascular disease. This study highlights the need for systematic population-based evaluation of CVD risk in order to promote equitable CVD outcomes.

Introduction The Hepatitis B virus that can cause liver cancer is highly prevalent in the Gambia, with one in ten babies at risk of infection from their mothers. Timely hepatitis B birth dose administration to protect babies is very low in The Gambia. Our study assessed whether 1) a timeliness monitoring intervention resulted in hepatitis B birth dose timeliness improvements overall, and 2) the intervention impacted differentially among health facilities with different pre-intervention performances. Methods We used a controlled interrupted time series design including 16 intervention health facilities and 13 matched controls monitored from February 2019 to December 2020. The intervention comprised a monthly hepatitis B timeliness performance indicator sent to health workers via SMS and subsequent performance plotting on a chart. Analysis was done on the total sample and stratified by pre-intervention performance trend. Results Overall, birth dose timeliness improved in the intervention compared to control health facilities. This intervention impact was, however, dependent on pre-intervention health facility performance, with large impact among poorly performing facilities, and with uncertain moderate and weak impacts among moderately and strongly performing facilities, respectively. Conclusion The implementation of a novel hepatitis B vaccination timeliness monitoring system in health facilities led to overall improvements in both immediate timeliness rate and trend, and was especially helpful in poorly performing health facilities. These findings highlight the overall effectiveness of the intervention in a low-income setting, and also its usefulness to aid facilities in greatest need of improvement.

BACKGROUND:Physical activity is crucial for our wellbeing. Since the COVID-19 pandemic emerged, physical activity behaviour has changed globally, and social inequalities that already exist in physical activity have increased. However, there is limited knowledge of how these inequalities have evolved in Sweden. Thus, the aim of this study was to assess the prevalence of physical activity, and the socioeconomic inequalities in physical activity before and during the COVID-19 pandemic. METHODS:This study analysed data from the national 'Health on Equal Terms' survey which was conducted on participants between 16 and 84, through a repeated cross-sectional design in 2018 (pre-pandemic) and 2021 (during the pandemic). The socioeconomic variables included gender, age, education, occupation, income, and place of birth. For both years, the prevalence of low physical activity, the absolute risk differences, the slope index of inequality, and the slope index difference for each of the variables were calculated. RESULTS:The level of physical activity increased for the total population studied. However, the social inequalities that existed in 2018 increased over time and across age, education, occupation, income, and place of birth, but not with regard to gender. CONCLUSIONS:Even though the Swedish population increased their levels of physical activity during the COVID-19 pandemic, the social inequalities that already existed in physical activity increased. Interventions to increase the level of physical activity among the young, people with low socioeconomic status, and those born outside Sweden are needed to reduce these social inequalities, and to improve the Swedish population's wellbeing.

OBJECTIVES:The goal of the Swedish oral healthcare system is to achieve good oral health and equitable access to care for the entire population. However, considerable inequities in oral health and care are evident and occur across a range of social dimensions. This study uses an intersectional approach to examine complex inequities in unmet oral care needs among adults in Sweden over the period 2004-2021.METHODS:Data were obtained from 14 Health on Equal Terms surveys conducted during 2004-2021. The final sample was 129 473 individuals aged 26-84 years. Applying intersectional analysis of individual heterogeneity and discriminatory accuracy, inequities in unmet oral care needs were estimated across 48 intersectional strata defined by gender, age, educational level, individual disposable income and immigrant status.RESULTS:A high risk of unmet oral care needs was found among strata consisting of immigrants and those with low income. However, being an immigrant and/or having a low income did not universally entail a high risk but varied by the social position along other axes, particularly age and education. The discriminatory accuracy was moderate.CONCLUSION:Groups with certain social disadvantages are highly heterogeneous themselves. An intersectionality approach is important to prevent the risk of stigmatizing large heterogenous groups while failing to identify the most vulnerable strata. The discriminatory accuracy analysis suggested that further policy and/or interventions may be the most effective if approaching the whole population, combined with selected targeted interventions directed at the most disadvantaged social strata.

Loneliness among older adults is a public health problem that has received particular attention since the emergence of the COVID-19 pandemic. Studies to date have however found a rather modest psychosocial impact of the pandemic on older adults, and scarce research has analyzed this impact using a comprehensive equity lens. The present study used an intersectional approach to examine social inequalities in loneliness before and during the early phase of the pandemic among older adults receiving eldercare in Sweden. The study population (analytical N = 205,529) came from two waves (2019 and 2020) of a total population survey to all older adult (>65 years of age) home care recipients and nursing home residents in Sweden. Loneliness was self-reported by a single-item measure, and survey data were linked to population register data on age, gender, residential setting, income, and country of birth. Additive binomial regression models were used to estimate prevalence differences and discriminatory accuracy according to an analysis of individual heterogeneity and discriminatory accuracy (AIHDA) approach. Results showed inequalities in loneliness arising particularly in the intersection of country of birth, income, and residential setting. The inequalities widened slightly but ubiquitously following the emer-gence of the pandemic in 2020, with particularly nursing home residents emerging as a risk group. The discriminatory accuracy of inequalities was consistently low to moderate throughout the analyses but increased marginally during the pandemic in 2020. The study illustrates how social inequalities engenders heterogeneity in the psychosocial risk of older adults before and during the pandemic. These findings should stimulate more nuanced and equity-oriented depictions, research and policies about loneliness among older adults in the peri-pandemic era.

BACKGROUND:According to post-structural policy analyses, policies and interventions aiming at reducing social inequalities have been found to be part in producing and reifying such inequalities themselves. Given the central role of health inequalities on the public health policy agenda globally it seems important to examine the way policy on health inequalities may potentially counteract the goal of health equity. The aim of this intersectional policy analysis, was to critically analyze the representation of health inequalities in a government bill proposing a national strategy on alcohol, drugs, tobacco and gambling, to examine its performative power, and to outline alternative representations.METHOD:A post-structural approach to policy analysis was combined with an intersectional framework. The material was analyzed through an interrogating process guided by the six questions of the "What's the problem represented to be?" (WPR) approach. Thus, the underlying assumptions of the problem representation, its potential implications and historical background were explored. In a final step of the analysis we examined our own problem representations.RESULTS:The recommendations found in the gender and equity perspective of the bill represented the problem of health inequalities as a lack of knowledge, with an emphasis on quantitative knowledge about differences in health between population groups. Three underlying assumptions supporting this representation were found: quantification and objectivity, inequalities as unidimensional, and categorization and labelling. The analysis showed how the bill, by opting into these partly overlapping assumptions, is part of enacting a discourse on health inequalities that directs attention to specific subjects (e.g., vulnerable) with special needs (e.g., health care), in certain places (e.g., disadvantaged neighborhoods). It also showed how underlying processes of marginalization are largely neglected in the bill due to its focus on describing differences rather than solutions. Finally, we showed how different intersectional approaches could be used to complement and challenge this, potentially counteractive, problem representation.CONCLUSIONS:The problem representation of health inequalities and its underlying assumptions may have counteractive effects on health equity, and even though some of its strengths are raised, it seems to be profoundly entangled with a system resisting the kind of change that the bill itself advocates for. If carefully used, intersectionality has the potential to support a more comprehensive and inclusive equality-promoting public health policy and practice.

Objective: To assess whether the implementation of a results-based financing (RBF) project in The Gambia resulted in (1) improved national vaccination coverage (2) higher coverage in intervention than non-intervention areas, and (3) improvement in rural-urban coverage inequality.Methods: The study used a difference-in-differences design, based on repeated cross-sectional data from The Gambian Demographic and Health Surveys 2013 (N = 1650) and 2020 (N = 1456). Full vaccination (receipt of one BCG, 3 OPV, 3 DTP, and 1 measles-containing vaccine doses) and rural-urban vaccination inequality were our outcome variables. The intervention, RBF, was implemented in 5 of the 7 health regions. Covariates controlled for included child's sex, child's birth order number, socioeconomic status, ethnicity, distance from health facility, maternal education, mother's age group, mother's marital status, and mother's work status. Poisson regression with robust variance was used to estimate whether cover-age changed, and difference-in-differences and difference-in-differences-in-differences were used to 'assess differences in vaccination coverage change and change in inequalities, respectively.Results: Total crude full vaccination coverage in The Gambia was 76% in 2013 and 84.6% in 2020. Overall vaccination significantly increased by 16% (95% CI: 9% to 24%) in 2020 compared to 2013, but with a smal-ler increase in intervention relative to non-intervention areas [PRR 0.88 (CI: 0.78-0.99)]. Rural-urban inequality in vaccination coverage decreased more - by 13% [0.87 (0.78-0.98)] - in RBF than non-RBF regions.Conclusion: Vaccination coverage improved over the study period though we have no evidence to ascribe the coverage gains to the RBF intervention. However, our study suggests that the RBF project has con-tributed to reducing rural-urban inequalities in the regions it was implemented.(c) 2022 The Authors. Published by Elsevier Ltd.
