Excess body fat mass indicators as predictors of dyslipidemia in 80+ population

BACKGROUND: As evidenced in many studies, high body mass index (BMI) in both children and adults is associated with dyslipidemia. Still, similar data on people aged 80 years and more are scarse. Aims of this study were to answer whether the anthropometric measurements which indicate excess body mass are informative on lipid status in 80+ population, and are these equally significant for both sexes. METHODS: The study included 325 people over 80 years of age with preserved cognitive function (80-101 yrs, mean 88.3±3.5 yrs, 74.5% women, 11.4% immobile). We measured their height and weight, waist circumference (WC) and hip circumference, which we used to calculate BMI, waist-to-hip ratio (WHR), and waist-to-height ratio (W/Ht). The lipid profile analyses included total cholesterol (TC), triglyceride, high density (HDL-C) and low density (LDL-C) lipoprotein cholesterol. Dyslipidemia was diagnosed if plasma levels of TC, and/or triglycerides, and/or LDL-C were elevated, or if any of the before-mentioned came with decreased HDL-C level. RESULTS: Dyslipidemia was more prevalent in elderly women than in men (p<0.001), as well as in women with BMI≥30 kg/m2, when compared with non-obese women (p<0.01). Furthermore, women with central obesity (determined from WC according to EU standards) (p<0.01) and those with WHR≥0.80 (p<0.05), had dyslipidemia more frequently than women with normal body fat distribution. T-test showed significant differences in means of all tested anthropometric variables between dyslipidemic and non-dyslipidemic women, while men differed only in triceps skinfold. Indicators of body fat distribution (BMI, WHR, W/Ht, WC) were better correlated with lipid profile in women that in men. Similar results on the body fat distribution indicators association with dyslipidemia were obtained by using logistic regression, adjusted for sex and years of smoking. CONCLUSION: Indicators of body fat distribution can predict dyslipidemia in 80+ population, more effectively in elderly women than in men.
