2)服药者比例与乡镇人口长寿水平指标90+/65+、100+/65+存在明显正相关,表明医疗延长了存活年限,降低了死亡风险。同时,还有研究表明:表面上历次人口普查乡村人口长寿率高于城市,但实际通过对死亡率的研究发现,城市人口比乡村更长寿[21],即医疗条件更好的地区有助于提高长寿水平,与此次调查结果一致。

3)饮酒与长寿的关系在学界存在较大争议。本文统计结果显示,90+/65+、100+/65+数值与长寿人口饮酒者比例呈正相关,调查的长寿人口喜爱饮用当地生产的黄酒,是否与长寿有关,是否当地其他非长寿人群也喜爱饮酒,还有待于深入调查和论证。

4)长寿人口血缘兄弟姐妹的寿命与90+/65+间存在正相关性,即血缘亲属寿命长的乡镇,人口长寿水平也高。

3 结论

调查了江苏南通11 个镇162 名长寿人口,其中大多数是女性,其已故兄弟姐妹的平均寿命为79.14 岁,显著高于南通同期的人口预期寿命,表明遗传因素与长寿具有相关性。长寿人口中大多数以素食为主或饮食平衡、吃肉较少,性格乐观开朗、体型较瘦、每餐吃八成饱者居多。11 个镇多年的人口长寿水平排名稳定,通州区和如皋市东部乡镇人口长寿水平普遍高于如皋市西部乡镇。长寿水平与行为、环境、遗传三类要素间的相关分析显示:大米中Sr 含量(负相关)、服药者比例、饮酒者比例和血缘兄弟姐妹寿命4 个因素与长寿水平具有相关性。
