溧阳市社区诊断人群体重、腰围自报数据准确性分析

Accuracy analysis of self-reported weight and waist circumference of community diagnosis population in Liyang

目的了解溧阳市居民自身体重、腰围的知晓现状,以及自报数据的准确性及影响因素。方法采取多阶段整群、随机、系统抽样方法,抽取的家庭中调查年龄≥18岁居民,比较分析体重、腰围的自报值与实测值。结果调查8 882人,人群体重知晓率为88.67%,腰围知晓率为76.78%;体重自报值平均偏低(0.30±4.25)kg,且不同性别、年龄的自报值均低于实测值;腰围自报值平均偏高(0.10±5.62)cm;体重、腰围自报值准确率分别为64.40%、55.65%,年龄、文化程度、职业、身质指数与体重、腰围自报准确性均有关联(P值均<0.05)。结论应进一步加强对老年、退休在家、低文化程度、身体质量指数异常群体的健康宣教,增强居民自身健康指标的掌握程度。

Objective To investigate self-awareness of weight and waist circumference among residents in Liyang; to study accuracy of self-reported values and influencing factors. Methods Residents aged 18 years or above were selected by multi- stage cluster randomized systematic sampling method in Liyang. Self-reported weight and waist circumference values were col- lected and compared with measured values. Results A total of 8 882 subjects were investigated , self-awareness rates of weight and waist circumference were 88.67% and 76.78%, respectively. Average self-reported values of weight was （0.30± 4.25） kg less than measured value, self-reported weight values were less than measured value among subjects of different gen- ders and ages. Average self-reported waist circumference was （0.10±5.62） cm more than measured value. The accuracy rates of weight and waist circumference were 64.40 %, and 55.65 %, respectively, which were correlated with age, education level, occupation and body mass index （all P〈0.05）. Conclusion In order to improve self-awareness of health indicators ,it is nec- essary to enhance health promotion among aged, retired residents with lower education background and residents with abnor- mal body mass index.
