Experiences with food insecurity and risky sex among low-income people living with HIV/AIDS in a resource-rich setting.

Background: Forty-nine million individuals are food insecure in the United States, where food insecurity and HIV/AIDS are prevalent among the urban poor. Food insecurity is associated with risky sexual behaviours among people living with HIV/AIDS (PLHIV). No qualitative studies, however, have investigated the mechanisms underlying this relationship either in a resource-rich setting or among populations that include men who have sex with men (MSM).

Overweight, obesity and chronic kidney disease.

The sharp rise in the prevalence of chronic kidney disease (CKD) that parallels an increase in the prevalence of obesity in the recent years is a cause for great concern. CKD increases the rate of cardiovascular disease (CVD), development of end-stage renal disease, and leads to premature death. Although no direct causality link between obesity and CKD can yet be established, this appears highly likely.
