农村与城市80岁以上成功老龄人群生物学指标的比较

目的 了解农村与城市80岁以上成功老龄生物学指标状况.方法 2007年11月随机抽取广西巴马瑶族自治县80岁以上成功老龄73例,同期抽取广西南宁市80岁以上成功老龄31例.测量二组老人的身高、体重、血常规、电解质、血脂、血糖,计算体重指数(BMI),并对影响长寿的相关生物学指标进行多因素回归分析.结果 成功老龄血脂、血糖、血常规、电解质均在正常范围,城市成功老龄的平均年龄小于农村成功老龄,平均体重、身高大于农村成功老龄,超重人数明显多于农村成功老龄,在高密度脂蛋白胆固醇(HDL-C)低的比例、空腹血糖值、平均血红蛋白量、平均血红蛋白浓度、钠、氯、镁高于农村成功老龄,载脂蛋白A(ApoA)、载脂蛋白B(ApoB)、淋巴细胞、中性粒细胞、红细胞、红细胞容积低于农村成功老龄;多因素回归分析,结果显示城市成功老龄的年龄与甘油三酯(TG)呈负相关,农村成功老龄的年龄与BMI、HDL-C呈负相关.结论 城市和农村成功老龄的部分生物学指标存在差异,但成功老龄生物学指标具有正常稳定的特征,而保持正常稳定的生物学基础是以保持正常体重为基准,以科学行为方式和良好生态环境为前提.

The comparative study of the biological indexes of the successful aging over 80 between countryside and city

Objective To explore the biological indexes of successful aging over 80 years old between countryside and city. Methods 73 cases of successful aging over 80 were randomly selected in Bama in Nov 2007,and 31 cases of successful aging over 80 were randomly selected in Nanning simultaneously.The body height,body weigh,blood analysis,electrolytes,blood fat,blood sugar were measured,and BMI was calculated.Results The mean of blood fat,blood sugar,blood analysis and electrolytes was in the normal range.The averag...
