Prevention of type 2 diabetes: an update.

With the rising tide of the diabetes epidemic leading to increased morbidity and mortality (primarily from cardiovascular disease), together with failure to control the disease and its associated complications, prevention of diabetes appears to be the logical option for curbing this epidemic. Several trials have been completed, and others ongoing, using various strategies for diabetes prevention. In this review, we provide an update on diabetes prevention strategies, highlighting the rationale behind such interventions, together with an outlook of the ongoing efforts that are likely to provide additional options for patients at risk for diabetes.

Cardiovascular disease in diabetes and the cardiometabolic syndrome: focus on minority women.

Diabetes and the cardiometabolic syndrome (CMS) are evolving as global epidemics. In the United States, diabetes affects 20 million people, with 47 million afflicted with the CMS. These disorders have a higher propensity for women, particularly in minority populations with disproportionate increase in cardiovascular disease (CVD) morbidity and mortality. Despite the decline in CVD mortality rates in the general population over the past 35 years parallel to the advances in therapeutic interventions, these rates have increased in women with diabetes. Early preventive measures for CVD risk factor through behavioral and lifestyle modification, smoking cessation, and reduction in psychosocial stressors, as well as pharmacotherapy, are among the currently supported approaches to CVD risk reduction in this high-risk population. In this article, we discuss CVD in people with diabetes and the CMS, with emphasis on minority women, a particularly vulnerable population.

Differential effect of obesity on bone mineral density in White, Hispanic and African American women: a cross sectional study.

Osteoporosis is a major public health problem with low bone mass affecting nearly half the women aged 50 years or older. Evidence from various studies has shown that higher body mass index (BMI) is a protective factor for bone mineral density (BMD). Most of the evidence, however, is from studies with Caucasian women and it is unclear to what extent ethnicity plays a role in modifying the effect of BMI on BMD.A cross sectional study was performed in which records of postmenopausal women who presented for screening for osteoporosis at 2 urban medical centres were reviewed. Using logistic regression, we examined the interaction of race and BMI after adjusting for age, family history of osteoporosis, maternal fracture, smoking, and sedentary lifestyle on BMD. Low BMD was defined as T-score at the lumbar spine < -1.Among 3,206 patients identified, the mean age of the study population was 58.3 +/- 0.24 (Years +/- SEM) and the BMI was 30.6 kg/m2. 2,417 (75.4%) were African Americans (AA), 441(13.6%) were Whites and 348 (10.9%) were Hispanics. The AA women had lower odds of having low BMD compared to Whites [Odds ratio (OR) = 0.079 (0.03-0.24) (95% CI), p < 0.01]. The odds ratio of low BMD was not statistically significant between White and Hispanic women. We examined the interaction between race and BMD. For White women; as the BMI increases by unity, the odds of low BMD decreases [OR = 0.9 (0.87-0.94), p < 0.01; for every unit increase in BMI]. AA women had slightly but significantly higher odds of low BMD compared to Whites [OR 1.015 (1.007-1.14), p <0.01 for every unit increase in BMI]. This effect was not observed when Hispanic women were compared to Whites.There is thus a race-dependent effect of BMI on BMD. With each unit increase in BMI, BMD increases for White women, while a slight but significant decrease in BMD occurs in African American women.
