Each of the various determinants of the sexual spread of HIV must not be considered in isolation. Instead, the interactive nature of those determinants should be accounted for in discussions of HIV epidemic dynamics.
The study presented here is an exploration of the implications of patterns of sexual behaviour for the spread of HIV in China, using a bio-behavioural macrosimulation model. To reflect the uncertainty surrounding key parameters, analyses of varied scenarios are used to show a range of possible outcomes consistent with variations in selected biological and behavioural inputs. The latter are estimated from a nationwide survey of sexual behaviour recently conducted in China, a country with an emerging HIV/AIDS epidemic, where it is feared that HIV/AIDS will spread to the general population via heterosexual transmission. The results highlight the primacy of the levels and distribution of sexual activity in the population. They offer some guidelines for understanding and interpreting the potential implications of current and prospective changes in sexual behaviour for the spread of HIV/AIDS in the world's largest population, and also highlight the need to collect better data on sexual behaviour for the estimation of key model inputs.
The household living arrangements of older persons – whether living alone, with a spouse or partner, with their children or in multi-generational households – can be an important factor associated with their health, economic status and overall well-being. Understanding the patterns and trends in older persons’ living arrangements is thus relevant for global efforts to achieve the sustainable development goals, in particular those targeting poverty, hunger and health. The United Nations Database on the Households and Living Arrangements of Older Persons 2018 presents evidence drawn from 672 unique data sources, including census and survey microdata samples archived at IPUMS-International and household rosters from Demographic and Health Surveys, among other sources. The resulting dataset describes older persons’ households across 147 countries or areas, representing approximately 97 per cent of persons aged 60 or over globally.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
