Social capital, migration stress, depression and sexual risk behaviors among rural-to-urban migrants in China: a moderated mediation modeling analysis.

ABSTRACT: Background: Few studies have examined the complex relationship of migration stress and depression with sexual risk behaviors among migrants. The relationship between migration stress and sexual risk behaviors may be mediated by depression, and the mediation process may be modified by social capital. The study aims to investigate this moderated mediation mechanism among rural-to-urban migrants. Methods: Data were collected from rural-to-urban migrants in China. Migration stress, depression, and social capital were measured with validated scales and used as predictor, mediator and moderator, respectively, to predict the likelihood of having sex with risk partners. Mediation and moderated mediation models were used to analyze the data. Results: Depression significantly mediated the migration stress-sex with risk partner relationship for males (the indirect effect [95%CI]?=?0.36 [0.08, 0.66]); the mediation effect was not significant for females (0.31 [-0.82, 0.16]). Among males, social capital significantly moderated the depression-sex with risk partner relation with moderation effect -0.12 [-0.21, -0.04], -0.21 [-0.41, -0.01] and -0.17 [-0.30, -0.05] for total, bonding and bridging capital respectively. Conclusion: Social capital may weaken the association between migration stress and sexual risk behavior by buffering the depression-sexual risk behaviors association for males. Additional research is needed to examine this issue among females.

Project description:Atmospheric particulate matter (PM) is a recognized risk factor for the global burden of disease in human populations. We are presenting here the application of toxicogenomics in the evaluation of the toxic effects of organic content of atmospheric particle matter (PM), from urban and rural environments (city of Barcelona and village of La Pobla, NE Spain), using the developing zebrafish embryo. The main goal is to identify the metabolic pathways involved in the adverse effects observed in zebrafish embryos exposed to PM organic content from urban and rural environments, also allowing the selection of genes of interest that are differentially expressed. The relevance of particle size to the PM toxicity is also addressed. Indeed, the zebrafish embryos were exposed to PM of aerodynamic diameter larger than 7.2 μm and smaller than 0.5 μm (PM10 and PM0.5, respectively). PM0.5 concentrated biological and toxic activities linked to organic substances. Transcriptomic analyses showed strong induction of the AhR signalling pathway (a.k.a. dioxin-like activity) for embryos exposed to both rural and urban extracts, correlating with the concentrations of PAHs. Urban extracts, with strong contribution of traffic emissions, specifically de-regulated oxidative stress-related genes, as well as pancreatic and eye-lens specific genes, two organs known to be affected by air pollution in humans. Exposure to rural extracts, with high contribution of wood burning emissions, affected genes implicated in basic cellular functions, in agreement with their strong embryotoxicity. Extracts from rural and urban samples elicited both common and specific transcriptome responses, suggesting different potentially adverse outcomes depending on PM source and composition.
