Although age at first sex is considered a measure of sexual risk and vulnerability for HIV infection, there is a dearth of literature on age at sexual debut in the Canadian context. This study examined time variations to first sex among heterosexual African, Caribbean, and Black (ACB) men in four Ontarian cities. A population-based retrospective survey (n?=?879) on timing to first sexual intercourse was conducted between 2018 and 2019 among self-identified heterosexual ACB men 16 years or older and residing in London, Ottawa, Toronto or Windsor. We used the lognormal survival analysis technique to examine variations in time to first sexual intercourse among age cohorts and between cities. The findings showed a generational shift in the pattern of sexual initiation, with younger heterosexual ACB men initiating sexual intercourse earlier compared with those currently older than 50 years. We observed those between 16 and 19 years, 20 and 29 years, and 30 and 39 years of age to have significantly higher risk ratios of TR?=?0.852, TR?=?0.869, and TR?=?0.855, respectively. At city level, the results show marked spatial variations, with youth in cities of Toronto, Ottawa, and London at the highest risk of early sexual debut relative to those in Windsor. Early initiation of first sexual intercourse among heterosexual ACB youth was observed with those in the larger cities being at a relatively higher risk. There is the need for programs aimed at delaying sexual debut among youth in general. It is, however, important to recognize the relative risk of those in the larger cities.
相似文献Methods: Our study was a secondary analysis of the Nigeria Demographic and Health Survey, a nationally representative dataset of men and women. Using logistic regression techniques and drawing on the structural influence model of health communication, we explored post-delivery women’s (N?=?13,889) exposure to mass media family planning messages in Nigeria.
Results: We found that 32% of post-delivery women were exposed to family planning messages on mass media in Nigeria. At the bivariate level, Muslim women were less likely to be exposed to mass media family planning messages compared with Christian women (odds ratio [OR] 0.39; 95% confidence interval [CI] 0.36, 0.41); however, the OR became positive once we controlled for structural determinants such as household wealth and education (OR 1.22; 95% CI 1.07, 1.40). In the multivariate analysis, we found that traditionalist women (OR 0.29; 95% CI 0.14, 0.58) and women from rural areas (OR 0.69; 95% CI 0.62, 0.76) were less likely to be exposed to such messages. Moreover, richer, better educated, and employed women were more likely to be exposed to mass media family planning messages compared with their poorer, less educated and unemployed counterparts. Similarly, living in the South West region was positively associated with higher odds of being exposed to such messages.
Conclusion: Findings were largely consistent with the structural influence model of health communication, as highlighted by inequalities in exposure to mass media messages. Based on these findings, we provide several policy recommendations. 相似文献
