老年人代谢综合征与饮食习惯的相关性分析

目的 探讨老年人群代谢综合征(MS)和饮食习惯的相关性.方法 连续抽取老年人781例,通过问卷调查和体检采集相关资料;采用Logistic回归分析方法分析饮食习惯与MS相关性.结果 老年人MS总患病率为40.7%,其中男性36.7%,女性55.4%,女性高于男性(P=0.000).低脂饮食组腰围(86.0±9.3)cm,与适中饮食组(88.8±8.5)cm及高脂饮食组(90.0±7.9)cm比较,差异有统计学意义(P＜0.05).低脂饮食组空腹血糖(5.78±0.98)mmol/L,与高脂饮食组(6.27±1.80)mmol/L比较,差异有统计学意义(P＜0.05).多元回归分析显示,以低脂饮食组为基准,适中饮食组OR值1.541(1.092～2.174),P＜0.05];高脂饮食OR值2.293(1.317～3.994),P＜0.01];适中饮食和高脂饮食是老年人群MS的独立危险因素.结论 适中饮食和高脂饮食是老年人群发生MS的危险因素,提倡在食物多样化的前提下,养成清淡低脂的饮食习惯,从而降低MS的患病率.

Abstract：

Objective To investigate the relationship between metabolic syndrome (MS) and diet style in the elderly. Methods The 781 old people were consecutively selected. Related data were collected by means of questionnaires and physical examinations. And logistic regression was performed to analyze if moderate and high fat diet were risk factors of MS. Results The total prevalence rate of MS in old people was 40. 7%, with 36.7% in old males and 55.4% in old females,and the prevalence rate of MS was higher in old women than in old men (P=0. 000). The significant differences in waist circumferences among three groups of low, moderate and high-fat diet (86.0±9.3) cm vs. (88.8±8.5) cm vs. (90. 0±7.9) cm, respectively (all P＜0.05)]were found. Fasting blood glucose showed a significant difference between two groups of low and high-fat diet, with the results of (5.78 ± 0.98) mmol/L and (6.27 ± 1.80) mmol/L, respectively ( P＜0. 05 ). The logistic regression analysis showed that odds ratio for people with moderate and high-fat diets were 1. 541 ( 1. 092-2. 174) and 2. 293 ( 1. 317-3. 994), respectively (P＜0.05), which indicated that moderate and high-fat diet was independent risk factors for MS in old people. Conclusions Both moderate and high-fat diets are risk factors of MS in old population, low fat diet with food balance is recommended to old population in order to decrease the prevalence of MS.
