RESUMO

Objective: Determine the prevalence of overweigh and obesity in a group of old women resident in BrasÃlia-DF using the Body Mass Index (BMI), and verify its association, inclusive in ages subgroups, with some laboratorial and clinical abnormalities. Methods: in a transversal study were evaluated 139 old women more than 60 years old, participants of the Gold Generation Project from the BrasÃlia Catholic University. The OMS and the CDC/NHANES III BMI index criterions were used to classify overweigh and obesity. The statistical analysis were significant with the p value <0,05. Results: The prevalence of overweight and obesity classified by OMS was respectively 43,9 e 33,8% while the obesity by CDC/NHANES III criteria was 53,3%. The frequencies of clinical and biochemistry abnormalities were high in all studied group. Hypercholesterolemia was observed in 36,7%, hypertriglyceridemia in 51,8%, hyperglycemia in 13,7%, hyperuricemia in 18,7%, high LDL in 59%, low HDL in 9,3%, arterial hypertension in 68% and osteopeny/osteoporosis in 85,7%. The women older than 70 years presented higher prevalence of hyperglycemia (p=0,025), hypertriglyceridemia (p = 0,01) and hyperuricemia (p = 0,01) when compared to 60 â 69 years. The women older than 70 years also presented significant higher means of glucose (p = 0,005), triglyceride (p = 0,008) and uric acid (p = 0,004), and significant lower mean of HDL (p=0,001). The comparison of the biochemical means of normal weight women with obese and overweight women showed an association of obesity with HDL level reduction (p=0,001 by OMS criteria and p=0,003 by CDC/NHANES III criteria), which was lower in obesity and overweight elder women. Hypertriglyceridemia (p=0,01) and arterial hypertension (p=0,025) were significant more prevailing in obesity elder women applying CDC/NHANES III classification. Conclusions: overweigh and obesity as well as the biochemistry and clinical abnormalities associated had a high prevalence in the present study. Hypertriglyceridemia, hypertension and low HDL were more prevalent in obesity women. With aging occur an increase of glucose, triglycerides and uric acid levels, and a decrease of HDL levels. Maybe CDC/NHANES III classification is more appropriated to identify obesity in old women. This results contributes to the understand of obesity in elderly and its clinical and biochemistry implications.
