title: Body fat distribution as a risk factor for coronary artery atherosclerosis in female cynomolgus monkeys.
abstract: Central fat deposition is associated with increased risk of coronary heart disease morbidity and mortality in women. Subcutaneous fat distribution was investigated as a potential factor that might exacerbate diet-induced coronary artery atherosclerosis (CAA) in female cynomolgus monkeys (Macaca fascicularis) which share with North American Caucasian women a gender-related protection against CAA. In a retrospective necropsy study (n = 36), the distribution of the antemortem ratio of subscapular/triceps skinfold thickness was divided at the mean and the two resulting groups were designated high and low for this variable. CAA was quantified as the mean cross-sectional intimal area based on nine coronary artery sections. The extent of CAA was significantly greater in the high skinfold ratio group as compared to the low skinfold ratio group. Ponderosity was closely associated with the skinfold ratio but was not a useful predictor of CAA. These findings suggest that female cynomolgus macaques may provide a primate model of the health consequences of regional fat distribution in women.
