Lipid profile and its association with body mass index in 4784 elderly male subjects / 中华老年医学杂志

ABSTRACT

Objective To evaluate lipid profile and its relationship with body mass index (BMI)in 4784 elderly male subjects. To explore the possibility of using an improvemem of dyslipidemia as an alternative target in the weight control in elderly male population. Methods 4784 elderly male subjects were surveyed with, the measurement of blood lipids and were grouped according to age (60-69, 70-79, 80-96 yrs) and BMI (＜18.5, 18.5-23.9, 24.0-27.9, ≥28.0 kg/m2), respectively.Results The mean levels of TC, LDL-C, TG and HDL-C (mmol/L) were (5.1±0.9)mmol/L,( 3.0±0. 8)mmol/L, (1.5±1.0)mmol/L and (1.3±0. 3)mmol/L, respectively. The prevalence of dyslipidemia was 44.8% (2141 cases) in this population, with specific abnormality rates in TC,LDLC, TG, HDL-C being 10. 4% (497 cases), 9.3% (445 cases), 29.8% (1425 cases) and 19.4% (928cases), respectively. Within all age groups, TG decreased dramatically and HDL-C incre ased with increasing age (P＜0.01), while the 60-69 yrs age group versus other age groups showed a tendency to an increment of TG, and a decrement of HDL-C. (P＜0. 05). Prevalences of overweight and obesity were 46.8% and 15.5% in the elderly male subjects, respectively. The level of TC increased with the increasing BMI, while HDL-C decreased. The differences in TG and LDL-C among various BMI groups were of no statistical significances. High TG and low HDL-C were predominant abnormalities amongst the oldest old, whose lipid profile resembled that of the 70-79 yrs age group.Whilst, the prevalences of overweight and obesity were at the lowest levels of 44.6% (228 cases) and 11.9% (61 cases), respectively. Conclusions High TG and low HDL-C are predominant abnormalities in elderly male subjects. TC level in the current population is higher than that from the national census in 2002. Prevalences of overweight and obesity are close to that in developed countries.TC and LDL-C levels are negatively related to age in the elderly male population, contrasting the correlation between HDL-C and age.
