- Abstract
The aim of this large, cross-sectional study was to describe the age- and sex-related variations of the somatotype, employing Heath and Carter's method, in the Chuvasha population residing in a rural region in central Russia. The second aim was to evaluate the association between the somatotype and different manifestations of aging, including blood pressure and indices of skeletal aging such as cortical index, radiographic hand osteoarthritis and the osseometric score. The investigated cohort included 802 males aged 18-89 years (mean 46.9) and 738 females aged 18-90 years (mean 48.6). Sex differences of somatotypes appear to be the strongest for endomorphy, with generally higher values in women. Endomorphy in males remained virtually unchanged after 30 years of age, but endomorphy in females kept increasing up to the 6th decade, and then subsequently decreasing. The largest difference of all somatotype components appeared between the ages 18-30 and 31-40. Thereafter, somatotypes remained practically unchanged. Mesomorphy continued to increase until the 5th decade in both sexes, while in females, endomorphy continuously increased until their 6th decade. In the 7th and 8th decades, a decrease in mean values was observed. Mesomorphy and ectomorphy showed opposite agerelated trends. The results of our study clearly suggest that in physique investigations, the somatotypes need to be studied in each sex separately; and in the studies of the young population, they also need to be adjusted to age. The present study provides convincing evidence for a connection between the indices of aging such as blood pressure and skeletal aging characteristics and physique characteristics. People with robust body build had higher mean values of SBP, DBP, TotOA and Osseometric score, while scrawny persons presented the lowest values. This last finding could hopefully be used as a diagnostic tool as well as a preventive measure in the management of hypertension, osteoarthritis and osteoporosis.
