This study explored Extension nutrition educators’ (NEs) perceptions of community members’ challenges and opportunities for achieving a healthy lifestyle. NEs represented various communities with low income across nine states. NEs across locations identified similar barriers (i.e., lack of access and availability of healthy and affordable foods; access to transportation; and financial insecurity) and opportunities (i.e., trustworthy and free nutrition education resources and programs; and access to food banks, food pantries, and health care professionals) that prevented or facilitated a healthful lifestyle. Future research should explore key community stakeholder and community member perceptions to guide the development of community-driven interventions.
Objective: Conducting exploratory factor analysis (EFA) with the existing home environment assessment - the Comprehensive Home Environment Survey (CHES), to identify scales related to food parenting practices. Methods: Parents of 3- to 5-year-old children (n = 172) completed the CHES surveys. After selected items from CHES were categorized into food parenting practice constructs, EFA was used to identify potential subconstructs. Internal consistency and Spearman correlation analysis were also conducted. Results: The EFAs identified 4 factors within the structure, 4 within coercive control, and 2 within autonomy support. Conclusions and Implications: The results provided preliminary evidence and support that the CHES can be used to measure food parenting practices. The study was limited to a small sample of non-Hispanic White and highly educated participants, less identified items within autonomy support, and lower internal consistency for several identified factors. Confirmatory factor analysis in a larger and more diverse sample is needed for future research.
Previous evidence suggests that children’s eating behaviors were largely influenced by the parent and home eating structure. This study examined the relationship between parenting styles (including authoritative, authoritarian, indulgent, and uninvolved), food parenting practices (within Structure, Coercive Control, and Autonomy Support constructs) and dietary intakes of preschoolers. Children aged 3–5 years and their parents were recruited from preschools/daycare centers and parents completed the surveys (n = 166). Dietary intakes were collected using the Harvard Service Food Frequency Questionnaire (HSFFQ), parenting style was assessed using the Parenting Dimensions Inventory-Short Version (PDI-S), and food parenting practices were measured using Comprehensive Home Environment Survey (CHES). The results showed that food parenting practices had a higher number of specific significant findings on children’s nutrient and food group intakes than parenting styles. Correlation analyses showed positive parenting practices within Structure were significantly related to healthier children’s intakes (e.g., vegetables, iron, and folate) and less unhealthy dietary intakes (e.g., sweets and total fats). Regression models show that children with authoritative parents consumed more fruits compared to children with authoritarian parents and indulgent parents. The results addressed the importance of parental influences for preschoolers’ healthy dietary intakes, which suggested that future interventions and educational programs could enhance parenting practices to impact child diet.
Adult physical activity levels influence youth physical activity levels, but the nature of this relationship is still unknown. Most research focusing on this topic has been conducted with accelerometers, which are ideal since self-report physical activity measures can be biased. However, self-report measures for physical activity are useful to include in studies to gather information at low-cost. The purpose of this study was to further develop a self-report adult-youth dyad measure of physical activity. This study was conducted using secondary data analysis of the physical activity measures used in an intervention on behavioral nutrition (iCook 4-H). Participants were a sample of 214 adults (M = 39.0, SD = 8.0 years) and youth (M = 9.4, SD = 0.7 years) pairs. Accelerometer data was collected for a subset of youth (n = 122). There was dependency between the adult-youth physical activity data, and a dyadic confirmatory factor analysis model showed good fit to the data and achieved metric invariance, a measure to determine if the same construct was being measured in both youth and adults. Invariance was confirmed across matched versus unmatched sex pairs and some evidence of invariance with youth accelerometer data. Based on study findings, when using self-report measures of physical activity, researchers should measure both members of the adult-youth dyad to get more accurate measurements. Further validation of these findings is needed using an objective physical activity measure, like accelerometers, with all participants and more diverse samples.
Many college students lack the ability to choose and/or prepare healthy meals, with consequences of convenient, but unhealthy food choices. The objective of this feasibility project was to determine whether cooking classes for college students would improve knowledge and behavior to eat healthfully and practice food safety. A series of 3 cooking classes was provided to students, focusing on simple, healthy recipes with inclusion of food safety education and nutrition instruction. Pre- and posttest surveys assessed nutrition knowledge; frequency of healthy eating; confidence, ability, and cooking frequency; and food safety knowledge. The classes were effective in increasing nutrition knowledge, cooking confidence, and ability, according to posttest surveys.
Self-reported measures for body mass index (BMI) are considered a limitation in research design, especially when they are a primary outcome. Studies have found some populations to be quite accurate when self-reporting BMI; however, there is mixed research on the accuracy of self-reported measurements in adolescents. The aim of this study is to examine the accuracy of self-reported BMI by comparing it with measured BMI in a sample of U.S. adolescents and to understand gender differences. This cross-sectional study collected self-reported height and weight measurements of students from five high schools in four states (Tennessee, South Dakota, Kansas and Florida). Trained researchers took height and weight of students for an objective measurement. BMI was calculated from both sources and categorized (underweight, normal, overweight and obese) using the Centers for Disease Control and Prevention's BMI-for-age percentiles. Participants ( n 425; 51⋅0 % female) had a mean age of 16⋅3 years old, and the majority were White (47⋅5 %). Limits of agreement (LOA) analysis revealed that BMI and weight were underreported, and height was overreported in the overall sample, in females, and in males. LOA analysis was fair for BMI in all three groups. Overall agreement in BMI categorisation was considered substantial ( Κ 0⋅71, P < 0⋅001). As BMI increased, more height and weight inaccuracies led to decreased accuracy in BMI categorisation, and the specificity of obese participants was low (50⋅0 %). This study's findings suggest that using self-reported values to categorize BMI is more accurate than using continuous BMI values when self-reported measures are used in health-related interventions.
Because diet quality (DQ) is associated with risk of chronic disease and is a common construct assessed in health-related research, validated tools to assess DQ are needed that have low respondent and researcher burden. Thus, content experts develop the Short Healthy Eating Index (sHEI) tool and an associated scoring system. The sHEI scoring system was then refined using a classification and regression tree (CRT) algorithm methodology with an iterative feedback process with expert review and input. The sHEI scoring system was then validated using a concurrent criterion validation process that included the sHEI DQ scores (calculated from responses from 50 participants) being compared to the participants’ Healthy Eating Index scores derived from 24 h recalls. The total HEI score from the CRT algorithm highly correlated with the 24 h recall HEI score (0.79). For individual food group items, the correlation between the CRT algorithm scoring and the 24 h recall data scoring ranged from 0.44 for refined grains to 0.64 for whole fruits. The sHEI appears to be a valid tool for estimating overall dietary quality and individual items (with correlations > 0.49) for fruits, vegetables, dairy, added sugar, sugar from sugar-sweetened beverages, and calcium.
Background:There is a need for improving long-term success in meal replacement programs and identifying the variables that affect weight loss and maintenance in a proprietary weight loss program that includes health coaching.Objective:The aim of this study is to evaluate weight-related eating behaviors of participants with clinically significant weight loss (CSWL) in a proprietary weight loss program.Study Design, Setting, and Participants:A cross-sectional sample of participants (n=1,454) enrolled in a proprietary weight-loss program that includes meal replacements and health coaching were queried via an on-line survey for weight-related eating behaviors and weight history.Main Outcome Measures and Analysis:Weight-related eating behaviors of routine restraint (RR), compensatory restraint (CR), susceptibility to external cues (SEC), and emotional eating (EE) were assessed using the Weight Related Eating Questionnaire. CSWL was defined as having achieved a weight loss greater than 10% of starting weight. Participants were dichotomized into those with CSWL (n=973) and with no CSWL (n=481). The relationship between CSWL (controlling for age and sex) as the dependent variable and weight-related eating behaviors (RR, CR, SEC, and EE) as the independent variables was assessed using logistic regression (Stata/SE 14).Results:Those with CSWL have higher odds of having RR (OR: 1.3, p<0.05) and CR (OR: 1.1, p<0.05) and lower odds of SEC (OR: 0.7, p<0.05) and EE (OR: 0.8, p<0.05) eating behaviors than those without CSWL.Conclusions:Weight-related eating behaviors of participants in proprietary meal replacement weight-loss programs who have successfully lost weight differ compared to those who have not. Knowledge of the relationship between CSWL and weight-related eating behaviors can be used by coaches to assist participants in reinforcing those behaviors that support weight-loss. These results are limited to participants who self-select for proprietary meal-replacement weight-loss programs and cannot be generalized to other weight-loss or maintenance programs.
Refugee-specific nutrition and cooking curricula addressing dietary acculturation barriers to food security are limited. A cooking curriculum was culturally adapted for Burundian and Congolese refugees to address their unique dietary acculturation experiences. A four-phase curriculum adaptation process (information gathering [literature review, researcher informed, and formative interviews; n = 18], preliminary adaptation design [data incorporation and steering committee; n = 5], pilot testing [n = 10 youth/adult dyads], and refinement) was applied to the existing evidence-based iCook 4-H curriculum using a five-strategy (peripheral, evidential, linguistic, constituent-involving, and sociocultural) cultural adaptation framework. A multiphase, two-cycle coding analytic process was completed within NVivo 12, followed by direct content analysis. Seventeen adaptations were made to the iCook curriculum, derived from varying combinations of four data sources (literature review, researcher informed, priority population, and steering committee), applying all five cultural adaptation strategies. A majority of the curriculum adaptations were derived from two or more data sources (71%) and were categorized within multiple adaptation strategies (88%). This study provided a community-based cultural adaptation process that could be used with various populations to address unique barriers and facilitators to food security. This innovative model addresses cultural needs while simultaneously aiming to improve health habits of refugee communities.
Patients commonly experience excessive weight gain (>10%) within 6 months to 1 year after renal transplant. The aim of this retrospective study of electronic medical records was to examine the association between number of nutritional counseling sessions with a registered dietitian nutritionist (RDN) with weight gain and lipids post-transplant. An analysis of covariance controlling for age and time between pre- and postmeasurements for weight, body mass index (BMI), and lipids was used to compare tertiles. Patients in tertile 1 (1–2 visits with RDN) experienced weight gain while patients in tertile 2 (3 visits) and tertile 3 (4–9 visits) did not gain weight. The change in weight was correlated with the changes in cholesterol (r = 0.23, P = .003) and triglyceride (r = 0.3, P = .0004). There were no differences among tertiles for female patients. Males in tertile 3 lost weight and improved BMI compared with male patients in tertile 1. Four or more visits with an RDN following renal transplantation are beneficial in preventing excessive weight gain. The change in weight was positively associated with blood lipids.
Pika Pamoja (Cook Together) is an eight-session cooking curriculum for Burundian and Congolese refugee families, culturally adapted from the evidence-based iCook 4-H curriculum to address dietary acculturation barriers to and facilitators of food security. The goal of this study was to determine the feasibility and acceptability of implementing Pika Pamoja. Researchers and a multilingual community aid implemented Pika Pamoja in a pre-post pilot intervention with randomized control (n = 5)/treatment (n = 5) dyads (youth/mother). Feasibility (recruitment/retention, implementation, fidelity testing, and assessment procedures) and acceptability (process and program evaluations) measures were collected. All 10 dyads (control and treatment) were retained throughout the study. All fidelity measures were 91% or above. The final youth assessment instrument included scales for cooking skills (alpha = 0.93), cooking self-efficacy (alpha = 0.90), openness to new foods (alpha = 0.81), and eating (alpha = 0.68), playing (alpha = 0.90), and setting healthful goals (alpha = 0.88) together as a family. The final adult instrument included scales for cooking, eating, and playing together (alpha = 0.68), kitchen proficiency (alpha = 0.89), and food security (alpha = 0.79). Participant feedback was uniformly positive. Based on these results, Pika Pamoja was feasible to implement and was accepted by the priority population. Larger scale studies to measure the effectiveness of Pika Pamoja to increase food security among refugee families are needed.
Communicating scientific results with community partners is often lacking in intervention programs, thus eB4CAST was developed to facilitate impact sharing. This article investigated using the eB4CAST dissemination tool to communicate impact from a campus-based obesity prevention program. Data from Get Fruved RCT university sites collected at baseline were used to generate eB4CAST reports. Experts (n = 13) and RCT sites (n = 15) were asked to provide feedback on eB4CAST reports based on appeal, understanding, and clarity. On all Likert items, participants rated above 7 on each (out of 10). Positive responses from open-ended questions included eB4CAST reports being clear, visually appealing, and aid in program understanding. Overall, eB4CAST was successful in relaying data and information for the Get Fruved program, thus a means for science communication that could be used in interventions. Utilizing infographics to report data and information is a feasible way to disseminate and communicate in a cost-effective, timely manner.
The objective was to determine if cooking skills and meal planning behaviors are associated with greater fruit and vegetable intake and lower body mass index (BMI) in first-year college students who are at risk for excessive weight gain. A cross-sectional analysis was conducted using baseline data from a multi-state research project aimed at preventing weight gain in first-year college students. Cooking type, frequency and confidence, self-instruction for healthful mealtime behavior intention, self-regulation of healthful mealtime behavior, and cup equivalents of fruits and vegetables (FV) were measured using validated surveys. BMI was calculated from measured height and weight. First-year students (n = 1108) considered at risk for weight gain from eight universities completed baseline assessments within the first month of entering college. Multiple linear regression was used to determine associations among independent variables of cooking patterns, meal planning behaviors, and dependent variables of fruit and vegetable intake and BMI, after controlling for the influence of sex. Cooking more frequently, cooking with greater skills, and practicing meal planning behaviors are associated with greater fruit and vegetable intake and lower BMI in first-year college students. Interventions aimed at improving health in college students may be enhanced by incorporating cooking and meal planning components.
The purpose of this review was to determine whether the recommendation to reduce saturated fatty acid (SFA) consumption to treat or prevent cardiovascular disease (CVD) is relevant in the context of current peer-reviewed, evidence-based literature. A literature review regarding SFA and CVD was conducted using articles from 2011 to 2018 through PubMed. Three hundred seventy-four articles were found, of which 211 were excluded. The remainder included 37 primary research articles and 21 reviews. All of the publications were examined using the Evidence Analysis Library Quality Criteria. Existing evidence supporting a reduction in SFA to treat/prevent CVD is limited and conflicting.
