The trajectory of an animal's growth in early development has been shown to have long-term effects on a range of life-history traits. Although it is known that individual differences in behaviour may also be related to certain life-history traits, the linkage between early growth or development and individual variation in behaviour has received little attention. We used brief temperature manipu...

This paper contributes to conflicting evidence on the link between poverty and risky sexual behaviour by examining the effect of wealth status on age at first sex, condom use, and multiple partners using nationally representative adolescents' data from Burkina Faso, Ghana, Malawi, and Uganda. The results show that the wealthiest girls in Burkina Faso, Ghana, and Malawi had later sexual debut co...

Several studies have reported an association between deviant behaviour and cortisol reactivity to stress. However, relatively few studies have investigated the relationship between psychobiological stress reactivity and sexual risk-taking behaviours. In this study, cortisol reactivity to the Trier Social Stress Test (TSST) was measured in 26 healthy young adults prior to the administration of a...

Since the advent of HIV/AIDS, sexuality studies in sub-Saharan Africa (SSA) have focused mainly on the sexual behaviour of the younger generation (15-49 years) and little has been done to understand the sexual behaviour of those a 50 years and above. The objective of this study is therefore to examine the covariates of high-risk sexual behaviour among men aged 50 years plus within the SSA regio...

The purpose of this paper is to understand how married and cohabiting men and women define risk and to identify the factors that influence risk perceptions in a setting with a high prevalence of HIV infection. A combination of qualitative and quantitative methods was used during a cross-sectional survey conducted among 248 men and 289 women in KwaZulu-Natal, South Africa. Forty in-depth intervi...

BACKGROUND The prostate is a key gland in the sexual physiology of male mammals. Its sensitivity to steroid hormones is widely known, but its response to prolactin is still poorly known. Previous studies have shown a correlation between sexual behaviour, prolactin release and prostate physiology. Thus, here we used the sexual behaviour of male rats as a model for studying this correlation. Henc...

OBJECTIVES Data from generalized epidemic settings have consistently found that patients on antiretroviral therapy (ART) reduce sexual risk behaviours, but how sexual behaviour changes in the general population in response to ART availability, including amongst HIV-uninfected and undiagnosed adults, has not been characterized in these settings. DESIGN General population open cohort. METHODS...

BACKGROUND In welfare institutions, it is essential to address the health-related needs of adolescent populations who often engage in sexual activities. This study examines the association between individual and interpersonal factors concerning sexual risk behaviour (SRB) among adolescents in welfare institutions in Malaysia. METHODS Data were derived from a cross-sectional study of 1082 adol...
