Primary effects of comprehensive lifestyle modification on status of pre-chronic diseases / 中华健康管理学杂志

ABSTRACT

Objective To evaluate the effectiveness of comprehensive lifestyle modification in the primary health care system on status of pre-chronic diseases in a conventional healthcare program.Methods Two hundred and twenty-nine adult volunteers in 5 conventional healthcare centers were divided into 4 groups:group of prehypertension(n=67),group of prediabetes(n=38),group of abnormity serum cholesterol(n=71)and group of osteopenia(n=53).A muhicomponent behavioral intervention including education,physical activity,dietary practice,cease smoke,calcium supplement and exposure to sunlight was conducted for 12 months.The main outcome of each group was blood pressure,blood glucose,serum cholesterol and bone mineral density.Results Over 12 months,compared with the status before intervention,participants in each group were statistically significantly improved,the mean net reduction in systolic BP/diastolic BP was 9.4 mm Hg/6.6 mm Hg(1 mm Hg=0.133 kPa,t=5.93/8.29.P＜0.05)in group of prehypertension;the reductions of blood glucose,serum cholesterol were 0.9 mmol/L(t=3.69,P＜0.05)and 0.5 mmol/L(t=4.09,P＜0.05)in group of prediabetes and group of abnormity serum cholesterol,and the increase of bone mineral density on lumbar spine was 0.015 g/cm2(t=2.03,P＜0.05)in group of osteopenia,Conclusions For chronic disease prevention,ater one year the comprehensive lifestyle intervention produced beneficial changes in diet,physical activity,and biochemical parameters.This type of intervention is a feasible option to prevent chronic disease and should be implemented in the primary health care system.
