A number of factors that have been identified as risk factors for falls are also associated with hip fracture, including lower-limb dysfunction, neurologic conditions, barbiturate use, and visual impairment. Given the prevalence of these problems among the elderly, who are at highest risk, programs to prevent hip fracture should include measures to prevent falls in addition to measures to slow bone loss.

Most HIV prevention literature portrays women as especially “vulnerable” to HIV infection by way of biological susceptibility and men’s sexual power and privilege. Conversely, heterosexual men are perceived as active transmitters of HIV but not active agents in prevention. Although the women’s vulnerability paradigm was a radical revision of earlier views of women in the epidemic, mounting challenges undermine its current usefulness. This paper reviews the etiology and successes of the paradigm as well as its accruing limitations. We conclude by re-issuing a call for an expanded model that acknowledges biology, gender inequality, and gendered power relations, but also directly examines social structure, gender and HIV risk for heterosexual women and men.

The relationship between depressive symptom scores on the Center for Epidemiological Studies Depression Scale (CES-D; L. S. Radloff, 1977) at each trimester of pregnancy and a decrement in either fetal growth or gestational duration was evaluated among 666 pregnant women. There was no association overall, but among 222 women from lower occupational status households, each unit increase on the CES-D at 28 weeks gestation was associated with a reduction of 9.1 g (95% confidence interval [CI] = -16.0, -2.3) in gestational-age-adjusted birth weight. When missing data were multiply imputed, the estimate was -4.6 g (95% CI = - 10.7, 1.5). CES-D score was unrelated to fetal growth or gestational duration in analyses among other potentially high-risk subgroups: smokers, women with a history of adverse outcome, and women with social vulnerabilities. These results raise the possibility that among lower status women, depressive mood may be associated with restricted fetal growth.

We present an assessment of studies published in the last decade that consider the relationship of stress and social support to preterm delivery or fetal growth retardation. Included in the review are all reports on the direct effects of stressors or psychological distress; the indirect effects of stressors or distress through health behaviours such as smoking; and the direct and buffering effects of social support. Although an important stimulus for recent stress research has been the attempt to explain racial and social class differences in birth outcome, the recent data show that stressful life events during pregnancy, though more common in disadvantaged groups, do not increase the risk of preterm birth. In contrast, intimate social support from a partner or family member appears to improve fetal growth, even for women with little life stress. Questions unanswered by the research to date are whether elevated levels of depressive symptoms affect pregnancy outcome, either directly or by encouraging negative health behaviours, and whether chronic (vs. acute) stressors are harmful. Additional research is also needed to determine whether psychosocial factors interact with specific clinical conditions to promote adverse pregnancy outcomes. Focusing on intimate support and how it benefits pregnancy outcome could lead to the design of more effective interventions.

Structural barriers to antiretroviral treatment (ART) adherence are economic, institutional, political and cultural factors, that collectively influence the extent to which persons living with HIV follow their medication regimens. We identify three sets of structural barriers to ART adherence that are salient in Southern Africa: poverty-related, institutional, and political and cultural. Examples of poverty-related barriers are competing demands in the context of resource-constrained settings, the lack of transport infrastructure, food insecurity, the role of disability grants and poor social support. Examples of institutional factors are logistical barriers, overburdened health care facilities, limited access to mental health services and difficulties in ensuring adequate counseling. Examples of political and cultural barriers are controversies in the provision of treatment for AIDS, migration, traditional beliefs about HIV and AIDS, poor health literacy and gender inequalities. In forging a way forward, we identify ways in which individuals, communities and health care systems may overcome some of these structural barriers. Finally, we make recommendations for further research on structural barriers to ART adherence. In all likelihood, enhancing adherence to ART requires the efforts of a variety of disciplines, including public health, psychology, anthropology, sociology and medicine.
