目的了解上海市北蔡镇老年人群体质量指数(BMI)与社区常见慢性病患病率的关系,为慢性病的预防提供参考依据。方法采用问卷方式调查常见慢性病患病及治疗,通过研究对象回忆25岁时的身高、体重,计算出25岁时BMI,分为低体重组、体重正常组与超重组。测量老年人目前的身高、体重,计算出目前BMI,分为体重正常组、超重组、肥胖组。使用美国GE公司双能X线骨密度仪对腰椎和左股骨近端进行骨密度测定。结果 25岁时BMI分组,骨质疏松症和糖尿病的患病率3组具有统计学差异(P<0.05)。目前BMI分组,骨质疏松症和高血压的患病率3组差异具有统计学意义(P<0.05)。结论上海市北蔡镇老年人骨质疏松症、高血压和糖尿病的患病率与BMI关系密切,建议从青少年至老年人均应合理营养,合理控制体重,坚持适当的体育活动,保持良好的BMI。
Objective To understand the relationship between the elderly population mass index (BMI) and the prevalence of common chronic diseases in Beicai, Shanghai and to provide a reference for the prevention of chronic diseases. Methods The questionnaire was used to investigate the prevalence and treatment of common chronic diseases. By studying the height and weight of 25-year-olds, the BMI of 25-year-old was calculated and divided into low-weight group, normal-weight group and overweight group. Measurement of the current height and weight of the elderly, calculate the current BMI, divided into normal weight group, overweight group, obesity group. Bone mineral density (BMD) of the lumbar spine and left femur was measured by GE GE dual-energy X-ray absorptiometry. Results The prevalence of BMI group, osteoporosis and diabetes at 25 years old was statistically different among the three groups (P <0.05). The prevalence of BMI grouping, osteoporosis and hypertension is statistically significant in the three groups (P <0.05). Conclusion The prevalence of osteoporosis, hypertension and diabetes in Beizai town of Shanghai is closely related to BMI.
