Associação entre perfil lipídico e adiposidade corporal em mulheres com mais de 60 anos de idade

OBJECTIVE: To verify the association between lipid profiles and overall or central obesity in women over the age of 60. METHODS: The sample was comprised of 388 women over the age of 60 (mean 69; standard deviation 5.9 years). The lipid profile was determined using total cholesterol (TC), HDL cholesterol (HDL-C), LDL cholesterol (LDL-C) and triglyceride (TG) levels. Overall obesity was determined using the body mass index (BMI) and skin fold (SF) measurements. Central obesity was determined using the waist circumference (WC) and waist - hip ratio (WHR). Statistical analysis was conducted using age adjusted partial correlation and one way ANOVA (p<0.05). RESULTS: The mean values found for the adiposity variables and lipid profile components indicate an elevated atherogenic risk. In addition, the indicators for overall and central obesity were directly related to TG levels and inversely related to HDL-C levels. CONLCUSION: The partial correlation analysis and the largest variance found for WC and WHR in comparison to the lipidogram components indicate that both methods could be useful in the early diagnosis of atherosclerosis.

BACKGROUND: The protective effect of cardiorespiratory fitness, regardless of obesity, has been recognized in adults. However, this association is still not clear in elderly individuals. OBJECTIVE: To analyze the association between hypertension and cardiorespiratory fitness in 1,064 elderly Brazilian women. METHODS: Central obesity was estimated by waist circumference and cardiorespiratory fitness by the 6-minutes walk test. ANOVA one way, chi-square and logistic regression were used for the statistical analysis. RESULTS: The prevalence of hypertension was 53.9%. The central obesity group had higher odds for hypertension when compared with the non-central-obesity group, in the same cardiorespiratory fitness group. Furthermore, both the central obesity and non-central obesity groups had a progressive increase in the odds ratio for hypertension, from the highest to lowest fitness groups, indicating an inverse relation between fitness and central adiposity. The non-central obesity group had the lowest odds ratios (OR), 1.49 (95%IC 0.97-2.28) and 1.54 (95%IC 0.94-2.51); whereas the central obesity group had an OR of 2.08 (95%IC 1.47-2.93), 2.79 (95%IC 1.79-4.33) and 3.09 (95%IC 1.86-5.12). CONCLUSION: Our findings indicated that the waist circumference measurement is a strong predictor of hypertension and suggested that the protective effect of cardiorespiratory fitness can be extended to elderly women, even to those with central obesity.BACKGROUND The protective effect of cardiorespiratory fitness, regardless of obesity, has been recognized in adults.

Influência da adiposidade global e da adiposidade abdominal nos níveis de proteína C-reativa em mulheres idosas

OBJECTIVE To investigate how overall and abdominal adiposity, measured by waist circumference (WC), body mass index (BMI), and sum of skinfolds (sigmaSK), affect plasma C-reactive protein levels (CRP) in elderly women. METHODS Study sample consisted of 387 women older than 60 years (mean age 68.9; standard deviation 5.9 years). BMI, WC, sigmaSK, and CRP levels were all measured. One-way ANOVA was performed to detect differences in study variables among the CRP levels investigated. Logistic regression analysis was used to determine the influence of body fat measurements on CRP levels. The significance level was set at p < 0.05. RESULTS The analysis of variance showed that mean WC was lower in women with normal CRP levels, as compared to those with high CRP levels. Logistic regression analysis examined the influence of BMI, WC, and sigmaSK quartiles on CRP levels, yielding the following results: only WC was predictive of elevated CRP levels, its highest quartile (cut-off point of 94.0 cm) showing levels nearly two times higher than its lowest quartile (odds ratio = 2.23; 95% confidence interval = 1.92-4.18; p = 0.012). CONCLUSION The results of this study indicate that abdominal adiposity is a strong predictor of elevated CRP levels.
