ObjectiveTo examine the knowledge about reproductive health, reasons and impact factors of induced abortion among migrant female workers in Baoan district of Shenzhen city for providing evidences to develop strategies on reducing unintended pregnancy-related induced abortion in the population.MethodsUsing convenient sampling, we selected two grade A tertiary hospitals in Shenzhen city of Guangdong province as study sites and conducted a face-to-face interview among 3 737 migrant female workers having induced abortion from March 2016 through March 2017 at the two hospitals. Information on demographics, abortion behaviors and knowledge about reproductive health were collected and decision tree analysis was adopted to analyze correlative factors of multiple induced abortions among the participants.ResultsValid responses were collected from 3 363 participants averagely aged 26.3 ± 5.4 years. Among the participants, the frequency of induced abortion differed significantly by marital status, whether living with family members, the number of sexual partners，and the perception of health risk related to induced abortion (all P < 0.001). Univariate analysis indicated that significant influencing factors of induced abortion incidence included marital status, with whom living together, the number of sexual partners, and the knowledge about induced abortion related health risk/infertility/reproductive tract inflammation/obstruction of fallopian tubes/backache/perforation of uterus. The results of decision tree analysis revealed that the participants with following characteristics were more likely to have multiple induced abortions: with more unmarried sexual partners, with more than 4 unmarried sexual partners and having correct perception on the risk of induced abortion, being divorced or widowed but having more sexual partners and living together with a spouse or family members, and being married and with fewer sexual partners but having a positive attitude towards unmarried pregnancy.ConclusionThe migrant female workers in Shenzhen city are lack of the consciousness on contraception and the knowledge about reproductive health and education programs for reproductive health in the population need to be promoted by relevant social departments.

Objective To survey on the sexual and reproductive health knowledge and the situation of repeated abortion in migrant female workers,and provide the evidence for introducing the corresponding public health policy. Methods Stratified random sampling method was used and a face-to-face questionnaire survey was conducted in migrant female workers who received abortion at three different-level hospitals in Bao′an district Shenzhen city. Results In this study,a total of 3 340 valid questionnaires were collected,and only 23.6% (782/3 308) of participants had received formal education about sexual and reproductive health. The overall awareness rate of sexual and reproductive health - related knowledge was 62.0%(12 426/20 040),and there were significant statistical difference among migrant females workers with different educational background(χ2=307.316,P≤0.05)and different income level(χ2=173.172,P≤0.05).

Human parechovirus (HPeV), a member of Picornaviridae family, is a widespread pathogen causing a wide spectrum of diseases. Like other picornaviruses, HPeV genome recombination has been detected. A total of 322 fecal samples were collected from children outpatients in Guangzhou, China, including 42 (13.0%, 42/322) HPeV‐positive samples detected in most of the infected children less than two years old. Seven HPeV genotypes (HPeV1, HPeV3, HPeV4, HPeV5, HPeV6, HPeV8 and HPeV14) were detected, among which, HPeV14, a rare genotype, was reported for the first time in children with acute gastroenteritis in China. This study revealed recombination events in eight samples. Clinical profiles did not yield statistical significance between children with HPeV infection alone and cases without pathogens detected. In conclusion, this study demonstrated that HPeV circulated in Guangzhou, China is diverse genetically, which provided evidence of recombination in HPeV in China. J. Med.

The association between CD14 gene C-159T polymorphism and tuberculosis (TB) susceptibility remains inconclusive. To derive a more precise estimation of the correlation, we performed a meta-analysis summarize the possible at a systematic manner. PubMed, HighWire and ScienceDirect databases covering all papers (up to November 2012) were searched. Statistical analyses were conducted by Rev-Man and STATA. Random- and fixed-effect models were used to estimate pooled odds ratios (ORs) and 95% confidence intervals (CIs), based on between-study heterogeneity. Eight published case-control studies investigating the relationship between C-159T polymorphism in CD14 gene and TB susceptibility were included. Results showed that individuals with T allele have an increased risk of TB compared with those with C allele (OR (95% CI) was 1.52 (1.11, 2.08) for TT vs. TC + CC, P < 0.001; 1.27 (1.01, 1.61) for T vs. C, P = 0.04). When stratified by ethnicity, variant TT homozygote carriers had an 86% increased risk of TB in Asians (OR (95% CI) was 1.86 (1.57, 2.20) for TT vs. TC + CC, P < 0.001), but not in Caucasians (OR (95% CI) was TT vs. TC + CC: OR = 0.78, 95% CI = 0.51-1.21, P = 0.61). This meta-analysis suggests that C-159T polymorphism in CD14 gene is associated with increased risk of TB, especially in Asians, but not in Caucasians.

目的 了解企业工人职业生产安全行为和发生职业伤害的相关性.为制定预和减少职业伤害对策提供依据.方法 采用分层抽样方法选取对象,发放自填式问卷进行横断面调查,内容包括一般人口学情况、工人对生产安全的态度、工作中的安全行为和过去12个月中个人因工作发生意外伤害的情况.结果 参与调查的1 741名工人平均年龄为26.42(±7.49)岁.其中有854名(49.6％)为男性.1 115名工人(65.0％)接受教育水平为初中,参加工作的时间平均为4.5(±4.36)年.多数工人的月收入集中在1001～2000元.安全行为与安全态度之间有相关(r=0.457,P＜0.001).Logistic回归分析结果表明性别和生产工作中的安全行为与发生意外伤害有关,其中女性相对于男性的OR值为0.321(0.198～0.521),安全行为较差的相对于较好者的OR值为2.428(1.577～3.737).结论 企业职工的安全意识和行为与职业伤害密切相关,年轻男性、工龄短、教育水平低和收入水平偏低工人是伤害的高危人群,应采取敢于措施,降低改高危人群的职业伤害发生率.

[Objective] To investigate the relationship between occupational safety attitudes and behaviors among manufacturing workers in Guangdong areas for the promotion of occupational safety behaviors and health.[Methods] A total of 10 585 forefront workers were selected from 46 manufacturing enterprises in Guangdong areas and were asked to complete self-administered questionnaires on their demographic characteristics,occupational safety attitudes(i.e.negative attitudes,attitudes toward safety policy,attitudes toward management support,and positive attitudes) and behaviors(i.e.work postures,operational safety,personal protections and health habits).Linear regression analyses were employed to test the relationship between occupational safety attitudes and behaviors.[Results] Of the 10 585 questionnaires delivered,9 020(85.22%) were returned and 7 906(87.65%) were valid.The mean age and the mean working age of the participants were(30.45±8.63) and(6.99±6.52) years,respectively,and 52.5% of them were male.Negative attitudes were negatively associated with each occupational safety behavior.No associations of attitudes toward management support and positive attitudes were found with personal protections.Positive associations were found between the other dimensions of occupational attitudes and behaviors.[Conclusion] Occupational safety attitudes are associated with occupational safety behaviors and the associations vary with attitudes and behaviors.It is suggested that in order to improve workers' safety behaviors,more efforts should be made to enhance safety attitudes.
