Abstract:
Objective To explore the relationship between early adulthood weight status and body weight changes from early adulthood to middle age and high-density lipoprotein cholesterol (HDL-C) level.Methods Data were obtained from China Multicenter Collaborative Study of Cardiovascular Epidemiology Study,which was conducted in 1998,15 participants population samples aged from 35-59 years old from 12 provinces were selected by random cluster sampling.Approximately 1 000 men and women in each sample population were surveyed for cardiovascular disease risk factors,body weight at age 25 from all participants were also obtained.Body mass index (BMI) at the age of 25 years was calculated with the weight at 25 years and the height measured during the survey,participants were divided into underweight (BMI ＜ 18.5 kg/m2,n =1 331),normal-weight (18.5 kg/m2 ≤BMI ＜24 kg/m2,n =10 400),overweight (24 kg/m2 ≤BMI ＜ 28 kg/m2,n =2 019) and obesity (BMI≥28 kg/m2,n =133) groups.Weight change was defined as the difference between the body weight at the age of 25 and at the survey and was grouped into ＜-7.5 kg (n =903),-7.5--2.6kg (n=1 883),-2.5-2.5 kg (n=2573),2.6-7.5 kg (n=2786),7.6-12.5 kg (n =2 674) and ＞ 12.5 kg (n =3 064).The association of body weight status in early adulthood and body weight change from early adulthood to middle age with HDL-C level was examined by logistic regression model.Results The prevalence of low HDL-C in underweight,normal weight,overweight and obesity groups at age of 25 years were 10.7％ (143/1 331),15.5％ (1 612/10 400),16.3％ (330/2 019) and 24.8％ (33/133),respectively (P for trend ＜ 0.01).The prevalence of low HDL-C for adult weight change were 8.8％ (79/903),8.0％ (151/1 883),10.5％ (269/2 573),13.4％ (373/2 786),19.1％ (511/2 674),and 24.0％ (735/3 064) (P for trend ＜0.01)for weight change of ＜-7.5 kg,-7.5--2.6 kg,-2.5-2.5 kg,2.6-7.5 kg,7.6-12.5 kg and ＞ 12.5 kg,respectively.Multivariate logistic regression showed that overweight and obesity at age of 25 years and subsequent weight gain till middle age were positively correlated with low HDL-C after adjusted other risk factors(all P for trend ＜ 0.01).Conclusion Overweight and obesity in early adulthood and significant adult weight gain from early adulthood to middle age were both independently associated with marked increases in the risk of low HDL-C in middle-aged Chinese men and women.Thus,body weight control at early adulthood could be a key strategy to reduce the incidence of low HDL-C at middle-aged population.
