Obesity and african americans: physiologic and behavioral pathways.

Although progress has been made to understand the association between physiological and lifestyle behaviors with regard to obesity, ethnic differences in markers of obesity and pathways towards obesity remain somewhat unexplained. However, obesity remains a serious growing concern. This paper highlights ethnic differences in African Americans and Caucasians that may contribute to the higher prevalence of obesity among African Americans.

Age-related decline in salivary dehydroepiandrosterone sulfate and associated health risks among African Americans.

Objectives: Dehydroepiandrosterone sulfate (DHEAS) declines with age and low endogenous DHEAS concentrations have been associated with obesity. In addition, DHEAS has been studied for its role in mood and wellbeing. However, limited data are available on salivary DHEAS concentrations in African Americans.

Exertional heat illness: the role of heat tolerance testing.

Exertional heat stroke (EHS) is a common clinical problem for both athletes and warriors; however, evidence-based guidance for return-to-play/duty (RTP/RTD) decisions is limited. Heat tolerance testing (HTT) has been proposed as a potential tool that, when combined with appropriate clinical information, may assist in RTP/RTD decisions. However, currently, no standard of care is available for performing HTT.

Self-reported sleep impairment and the metabolic syndrome among African Americans.

Objectives: African Americans (AA) experience a high mortality from cardiovascular disease (CVD), even without an increase in the prevalence of the metabolic syndrome (MetS). The potential role of sleep impairment in this phenomenon has not been studied. The current study examined the relationship between self-reported sleep and MetS components among AAs.
