Spontaneous obesity of adult Macaca cyclopis, M. fascicularis, and M. mulatta at the New England Regional Primate Research Center was examined. Weight, crown-rump length, anterior trunk height, and abdominal, subscapular and suprailiac skinfolds were measured in 33 female and 9 male M. cyclopis, 61 female and 19 male M. fascicularis, and 125 female and 23 male M. mulatta. Correlations of skinfolds with weight-height indices showed that, of the skinfolds measured, the abdominal skinfold is most highly correlated with all indices. The Quetelet Index (weight/height('2)), substituting crown-rump length for height, was used to define obesity. Animals having Quetelet Indices one standard deviation above the mean for their sex and species were considered obese. Spontaneous activity, feeding behavior, and social and self-directed behavior of pairs of obese and nonobese subjects, matched for age, sex, species, and cage type, were recorded. A total of 38 animals was observed. Food consumption by age-matched pairs of obese and nonobese M. fascicularis and M. mulatta females was also quantified. Behavior of obese and nonobese subjects did not differ at statistically significant levels. However, obese animals spent more time than nonobese animals in grooming and in inactivity, and nonobese subjects spent more time in very active locomotion. Gross quantities of food consumed by obese and nonobese subjects did not differ at statistically significant levels. As differences in behavior and food intake of obese and nonobese subjects seem inadequate to explain the range of adiposity in these populations, it is deduced that much of the obesity in these macaques has a genetic basis / acase@tulane.edu
