Age trends in adiposity and central body fat distribution among adult white men resident in Peterborough, East Anglia, England.

The pattern of fat distribution is related to a large number of variables of clinical importance. Many anthropometric indices have been derived which are surrogate measures of central fat distribution. However, systematic information on age variations in regional adiposity and central fat distribution is incomplete. The present study investigates the age variations in regional adiposity and five indices of central fat distribution among 262 adult White men resident in Peterborough, East Anglia, England. The five indices were studied: subscapular/triceps (STSR), abdomen/triceps (ATSR) and centripetal fat (CPFR) skinfold ratios, waist/hip ratio (WHR) and conicity index (CI). In general, the age patterns show progressive trend towards increasing central body fat distribution. The associations of age with all five central fat distribution indices were significant. These significant associations remained even after controlling for the body mass index (BMI). Therefore, this study provided evidence that there is a significant positive trend of increased central adiposity and fat distribution with increasing age in native English men. This trend is independent of BMI, which is a measure of overall adiposity. Such trends of enhanced fat accumulation in the central region of the body with age could have serious health implications especially with regard to chronic diseases like coronary heart disease (CHD), hypertension (HT) and non-insulin dependent diabetes mellitus (NIDDM). Future studies should also investigate whether the same phenomenon exists in other ethnic groups resident in Britain like South Asians who have very high prevalence of CHD and NIDDM.
