武汉市离退休老年人非酒精性脂肪肝及代谢综合征的相关性研究

目的 了解武汉市离退休老年人群非酒精性脂肪肝和代谢综合征的现况特点及2种疾病的相关性. 方法 抽样调查60岁及以上离退休老年人共718例,检测身高、体质量、腰围、血压、血糖、血脂、肝脏B超. 结果 所调查人群代谢综合征及非酒精性脂肪肝的患病率分别为25.2%及25.9%,而高血压、高血糖、高三酰甘油、低高密度脂蛋白胆固醇及腹型肥胖的患病率分别为89.2%,29.6%,40.3%,10.3%及38.6%;女性代谢综合征患病率高于男性(χ2=21.0,P<0.05);随着代谢综合征中异常组分的数目增多,非酒精性脂肪肝的患病率亦增加(男性χ2=82.9,女性χ2=23.7,均为P<0.01);老年人非酒精性脂肪肝患病率与代谢综合征呈显著正相关(男性OR=2.216,女性OR=4.848,均为P<0.01). 结论 离退休老年人群非酒精性脂肪肝及代谢综合征患病率较高,并且两者显著相关,应积极防治心血管疾病高危因子.

Study on correlation between nonalcoholic fatty liver disease and metabolic syndrome in retired old people in Wuhan

Objective To investigate the prevalences of the nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome( MS), and analyze the relationship between the two kinds of diseases in retired old people in Wuhan. Methods Seven hundred and eighteen retired old people (≥60 years old) were surveyed. The height, body mass index, waist circumference, blood pressure, blood glucose, blood lipid and liver B uhrasonography were examined. Results The prevalences of MS and NAFLD were 25.2% and 25.9% respectively, and the prevalences of hypertension, hyperglycemia, hypertriglyceridemia, low high-density lipoprotein cholesterol and abdominal obesity were 89.2%, 29.6%, 40.3%, 10.3% and 38.6% respectively. The prevalence of MS was higher in women than in men (χ2=21.0, P<0.05). The risk of NAFLD was increased with the increase of MS components numbers (male: χ2=82.9;female: χ2=23.7, both P<0.01). There was a positive correlation between the prevalence of NAFLD and MS in the elderly (male: OR=2.216;female: OR =4.848,both P<0.01). Conclusions The prevalences of NAFLD and MS are high in retired old people in Wuhan, and there is significant relationship between the two kinds of diseases. Great attention should be paid to the two risk factors for cardiovascular diseases in the elderly.
