The impact of ethnicity on the stress process in old age was examined using two surveys of Australians aged 60 years and older. Four different "ethnic strata" were defined: namely, mainstream Australians, British migrants, and non-British migrants--who were split on the basis of whether their English proficiency was good or poor. The ethnic stratum most different from mainstream Australian, non...

Heterosexual transmission of HIV in India is driven by the male use of female sex workers (FSW), but few studies have examined the factors associated with using FSW. This nationally representative study examined the prevalence and correlates of FSW use among 31,040 men aged 15-49 years in India in 2006. Nationally, about 4% of men used FSW in the previous year, representing about 8.5 million FS...

Little is known about the predictors of maintenance in organized exercise programmes. The aim of this study was to investigate the behavioral predictors of maintenance of exercise participation in older adults, using an integrated social psychological model. To this end, we carried out a prospective cohort study (n = 1,725; age 50 years or older) involving 10 different types of exercise program...

In this report we describe a new approach in HIV sentinel surveillance that was piloted in Viet Nam in 2009 and is currently being rolled out in all provinces. It comprises a brief behavioural questionnaire added to the HIV sentinel surveillance surveys conducted routinely among people who inject drugs, female sex workers and men who have sex with men. Timely reporting of data from this system ...

The authors contribute to the ongoing debate about the existence of a female leadership advantage by specifying contextual factors that moderate the likelihood of the emergence of such an advantage. The investigation considered whether the perceived role incongruence between the female gender role and the leader role led to a female leader disadvantage (as predicted by role congruity theory) or...

Research indicates that service utilization rates in migrant groups are low, although levels of distress appear high when compared with host populations. This paper systematically reviews quantitative and qualitative literature on factors associated with attitudes toward seeking psychological help among working age migrants. Data were extracted from MEDLINE, EMBASE, PsycINFO, Science Direct and...

A large number of female sex workers are children. Multiple studies demonstrate that up to 40% of women in prostitution started this work prior to age 18. In studies across India, Nepal, Thailand and Canada, young age at entry to sex work has been found to heighten vulnerability to physical and sexual violence victimisation in the context of prostitution, and relates to a two to fourfold increa...

Xq28 microduplications including the MECP2 gene constitute a 100% penetrant X-linked syndrome in males caused by overexpression of normal MeCP2 protein. A small number of cases of affected females have been reported. This can be due to the location of the duplicated material into an autosome, but it can also be due to the location of the duplicated material into one of the X chromosomes and ran...

Within and across species of primates, the number of males in primate groups is correlated with the number of females. This correlation may arise owing to ecological forces operating on females, with subsequent competition among males for access to groups of females. The temporal relationship between changes in male and female group membership remains unexplored in primates and other mammalian ...
