This study is carried out to determine the prevalence of metabolic syndrome (MS) in 148 women between 36 to 65 years using the International Diabetes Federation criteria in the North-Eastern part of India. The prevalence of MS and all its individual components were found to be significantly higher among postmenopausal as compared to premenopausal and perimenopausal women. Various components of MS except waist circumference shows a significant increase and homeostasis model assessment index for insulin resistance also showed significant differences between the three groups. All the MS diagnostic markers (except serum high density lipoprotein) showed a strong positive correlation with MS score among the groups. Further MS score correlated with indicators of insulin resistance evaluated. This study concluded that MS is highly prevalent among North-East Indian postmenopausal women seeking primary health care and its determinant factors related to age and sedentary habits. Thus recognizing and treating MS early with proper intervention can minimize complication.
Aging is associated with diminished secretion of growth hormone and the major endogenous mediator of growth hormone action, insulin-like growth factor I (IGF-I). Aging is also associated with decreased physical activity. Alterations in body composition characteristic of the aging process (increased fat mass and decreased lean body mass) may be related to the decline in anabolic effects of IGF-I with aging, decreased physical activity, or both. Guatemalan women often maintain a high level of physical activity during aging. The purpose of this study was to determine whether IGF-I concentrations correlated with physical activity level (determined by standardized scoring of a self-report questionnaire) and body composition (determined by bioelectrical impedance analysis) in elderly Guatemalan women. In 112 women aged 20-87 y, we found a progressively lower serum IGF-I with age (r = -0.732). In subjects > 60 y of age, the self-reported activity level was associated with a lower percentage body fat (P < 0.001) but there was no significant relation between physical activity level and either lean body mass or IGF-I. We conclude that there is a significant age-related decline in serum IGF-I concentrations in Guatemalan women, similar to that observed in both men and women in the United States. An increased level of physical activity in the elderly Guatemalan population was associated with reduced body fat but did not modify the expected reduction in circulating IGF-I concentrations that occurs with aging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
