HIV/AIDS is concentrated in impoverished communities. Two critical aspects of poverty are food insufficiency and substance abuse, and both are associated with sexual risks for HIV/AIDS in southern Africa. The current study is the first to examine both hunger and substance use in relation to sexual risks for HIV infection in South African alcohol serving establishments. ⋯ Food insufficiency and substance use may both contribute to HIV risks in South African shebeens. However, the influence of hunger and substance use on sexual risks varies for men and women. Interventions to reduce HIV transmission risks may be bolstered by reducing both food insufficiency and substance use.

As health equity researchers, we need to produce research that is useful, policy-relevant, able to be understood and applied, and uses integrated knowledge translation (KT) approaches. The Manitoba Centre for Health Policy and its history of working with provincial government as well as regional health authorities is used as a case study of integrated KT. Whether or not health equity research "takes the day" around the decision-making table may be out of our realm, but as scientists, we need to ensure that it is around the table, and that it is understood and told in a narrative way. ⋯ In the policy realm, showing the rates by socioeconomic group and trends in those rates, as well as incorporating information on absolute differences, may be better understood intuitively when discussing inequity. Health equity research matters, and it particularly matters to policy-makers and planners at the top levels of decision-making. We need to ensure that our messages are based on strong evidence, presented in ways that do not undermine the message itself, and incorporating integrated KT models to ensure rapid uptake and application in the real world.

In 2011, an interdisciplinary symposium was organized in Toronto, Canada to investigate prevailing models of health policy change in the knowledge translation literature and to assess the applicability of these models for equity-focused urban health research. The papers resulting from the symposium have been published together, in the Journal of Urban Health, along with this introductory essay. This essay describes how the different papers grapple in different ways with how to understand and to bridge the gaps between urban health research and action. ⋯ The first tension is whether the content of evidence or the context of decision making is the strong determinate of research impact in relation to health equity policy. The second tension is whether relationships between health equity researchers and decision makers are best viewed in terms of collaboration or of conflict. The third concerns the role that power plays in evidence-based policy making, when the issues at stake are not only empirical but also normative.

Globally, health and social inequities are growing and are created, actively maintained, and aggravated by existing policies and practices. The call for evidence-based policy making to address this injustice seems a promising strategy to facilitate a reversal of existing strategies and the design of new effective programming. ⋯ Moreover, the research base falls far short of a focus on the solutions to the complex multilevel drivers of disparities. This paper focuses upon recommendations to refocus and improve the public health research evidence generated to inform and create strong evidence-based recommendations for improving population health.

Low-income populations, minorities, and children living in inner cities have high rates of asthma. Recent studies have emphasized the role of psychosocial stress in development of asthma. Residence in unsafe neighborhoods is one potential source of increased stress. ⋯ In multivariate analyses adjusting for race/ethnicity, age, gender, socioeconomic status, number of smokers in the home and breastfeeding history, parents reporting feeling unsafe walking in the neighborhood were more likely to have a child diagnosed with asthma (OR = 1.89, 95%CI 1.13-3.14). Psychosocial stressors such as living in unsafe neighborhoods may be associated with asthma diagnosis in urban ethnic minority children. Addressing the increased asthma burden in certain communities may require interventions to decrease urban stressors.
