The association between family and community social capital and health risk behaviours in young people: an integrative review

Background: Health risk behaviours known to result in poorer outcomes in adulthood are generally established in late childhood and adolescence. These ‘risky’ behaviours include smoking, alcohol and illicit drug use and sexual risk taking. While the role of social capital in the establishment of health risk behaviours in young people has been explored, to date, no attempt has been made to consolidate the evidence in the form of a review. Thus, this integrative review was undertaken to identify and synthesise research findings on the role and impact of family and community social capital on health risk behaviours in young people and provide a consolidated evidence base to inform multi-sectorial policy and practice.<p></p> Methods: Key electronic databases were searched (i.e. ASSIA, CINAHL, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, Embase, Medline, PsycINFO, Sociological Abstracts) for relevant studies and this was complemented by hand searching. Inclusion/exclusion criteria were applied and data was extracted from the included studies. Heterogeneity in study design and the outcomes assessed precluded meta-analysis/meta-synthesis; the results are therefore presented in narrative form.<p></p> Results: Thirty-four papers satisfied the review inclusion criteria; most were cross-sectional surveys. The majority of the studies were conducted in North America (n=25), with three being conducted in the UK. Sample sizes ranged from 61 to 98,340. The synthesised evidence demonstrates that social capital is an important construct for understanding the establishment of health risk behaviours in young people. The different elements of family and community social capital varied in terms of their saliency within each behavioural domain, with positive parent–child relations, parental monitoring, religiosity and school quality being particularly important in reducing risk.<p></p> Conclusions: This review is the first to systematically synthesise research findings about the association between social capital and health risk behaviours in young people. While providing evidence that may inform the development of interventions framed around social capital, the review also highlights key areas where further research is required to provide a fuller account of the nature and role of social capital in influencing the uptake of health risk behaviours.<p></p&gt

Morbidity and related factors among elderly people in South Korea: results from the Ansan Geriatric (AGE) cohort study

BACKGROUND: A thorough examination of the morbidity and comorbidity profiles among the elderly and an evaluation of the related factors are required to improve the delivery of health care to the elderly and to estimate the cost of that care. In South Korea where the aged population is rapidly increasing, however, to date only one study using a limited sample (84 subjects) has provided information on morbidity and related factors among the elderly. Using a large, stratified, random sample (2,767 subjects) from the population-based Ansan Geriatric study, the present study sought to assess the morbidity and comorbidity, and to determine the relationships of these variables with sociodemographic and health characteristics in elderly people in South Korea. METHODS: A total of 2,767 subjects (1,215 men and 1,552 women) aged 60–84 years were randomly selected from September 2002 to August 2003 in Ansan, South Korea. Data on sociodemographic and health characteristics, and clinical diagnosis were collected using questionnaires. When available, the medical records and medications taken by the subjects were also cross-checked. RESULTS: Of the total subjects, 78.0% reported diagnosed disease, 11.0% had been cured, and 46.8% had been diagnosed with more than two diseases. The mean number of morbidities per person among elderly Koreans was 1.62 ± 1.35 (mean ± standard deviation), and women had a greater number of diseases per person than did men. The most common morbidities were chronic diseases such as hypertension, arthritis, and diabetes mellitus. In women, osteoporosis and arthritis were the second and third most prevalent diseases, respectively. Morbidity was significantly associated with gender, employment, household income, alcohol intake, self-assessed health status, and worries about health. CONCLUSION: These data will enhance understanding of the patterns of health problems among elderly Koreans and will contribute to the application of appropriate intervention strategies

Molecular Determinants and Dynamics of Hepatitis C Virus Secretion

The current model of hepatitis C virus (HCV) production involves the assembly of virions on or near the surface of lipid droplets, envelopment at the ER in association with components of VLDL synthesis, and egress via the secretory pathway. However, the cellular requirements for and a mechanistic understanding of HCV secretion are incomplete at best. We combined an RNA interference (RNAi) analysis of host factors for infectious HCV secretion with the development of live cell imaging of HCV core trafficking to gain a detailed understanding of HCV egress. RNAi studies identified multiple components of the secretory pathway, including ER to Golgi trafficking, lipid and protein kinases that regulate budding from the trans-Golgi network (TGN), VAMP1 vesicles and adaptor proteins, and the recycling endosome. Our results support a model wherein HCV is infectious upon envelopment at the ER and exits the cell via the secretory pathway. We next constructed infectious HCV with a tetracysteine (TC) tag insertion in core (TC-core) to monitor the dynamics of HCV core trafficking in association with its cellular cofactors. In order to isolate core protein movements associated with infectious HCV secretion, only trafficking events that required the essential HCV assembly factor NS2 were quantified. TC-core traffics to the cell periphery along microtubules and this movement can be inhibited by nocodazole. Sub-populations of TC-core localize to the Golgi and co-traffic with components of the recycling endosome. Silencing of the recycling endosome component Rab11a results in the accumulation of HCV core at the Golgi. The majority of dynamic core traffics in association with apolipoprotein E (ApoE) and VAMP1 vesicles. This study identifies many new host cofactors of HCV egress, while presenting dynamic studies of HCV core trafficking in infected cells

“Sex Is a sin”: Afro-Caribbean Parent and Teen Perspectives on Sex Conversations

This study characterized (a) mothers’ childhood and teenage experiences with sex conversations and (b) families’ perceptions of current parent–child sex conversations within two underserved Afro-Caribbean communities in the U.S. Fourteen dyads comprised of Haitian and Jamaican mothers and teens (aged 14–18) living in Miami, Florida, completed semi-structured interviews sharing their experiences with sex conversations. Researchers analyzed data using thematic content analysis. Mothers’ mean age was 41.85 years, (SD = 5.50) and teens’ mean age was 16.35 years, (SD = 1.31). Most mothers reported forbidden or little childhood experiences with parent–child sex conversations. They affected their sexual attitudes, behaviors, and ability to discuss sex with their children. Although some mothers benefited from educational and skill development others shared fear-based messages with their children that some teens believed adversely affected the mother–child relationship quality. Culturally appropriate, skill-based approaches are necessary to improve families’ communication self-efficacy for healthy sex conversations to occur in Afro-Caribbean families

Socioeconomic Differences in Alcohol-Specific Parenting Practices and Adolescents’ Drinking Patterns

Item does not contain fulltextThe aim of this study was to investigate to what extent alcohol-specific parenting practices relate to adolescents’ alcohol use, binge drinking, and alcohol-related problems, and whether these associations are moderated by socioeconomic status (SES), i.e. parents’ education level and family income. The present data were collected within the framework of a representative study on alcohol use among Dutch students. The present findings are based on data from respondents who had been drinking in the past year (81.5%), and of whom one of the parents had filled out a short questionnaire including SES characteristics (52%). The sample consisted of 1,344 adolescents. Adolescents were approached in a school setting; parents received a short questionnaire at the home address. The results show that applying strict rules about alcohol use and having qualitative good conversations about drinking alcohol seem to prevent adolescents from heavy drinking patterns, whereas parental alcohol use seems to promote adolescents’ drinking. A positive association was found between frequency of alcohol communication and availability of alcohol at home on the one hand and adolescents’ drinking on the other. Some moderating effects of SES were found
