钠摄入状况评价方法的比较研究
发布时间：2020-10-19 15:55
目的:评价膳食调查法、Kawasaki法、INTERSALT法、Tanaka法四种方法估算钠摄入量的准确性和可行性;并了解河北医科大学大学生钠的摄入状况、食物来源等,为制定减盐措施提供依据。方法:在河北医科大学招募健康志愿者274名,男女各半。采用膳食调查法计算志愿者钠的摄入量;同时收集受试者24小时尿液样本、时点(随机)尿液样本,测定尿液样本中钾、钠、肌酐的含量,对时点尿通过Kawasaki法、INTERSALT法、Tanaka法估算调查人群的钠摄入量。最后采用Bland-Altman法比较四种方法估算的钠摄入量和钠摄入量评价金标准(24h尿钠法)之间的一致性。考虑到钠排出途径的多样性,本研究分别在夏季(2017年6月底)和秋季(2017年11月底)各进行一次,以研究通过尿液推测钠摄入量的准确性和可行性。结果:1.金标准得到的钠摄入量结果274名对象被纳入到本研究。24h尿液收集法显示,夏季的调查结果为人均每天钠摄入量3043.0±1223.3mg(合成盐7.8±3.1g);秋季的调查结果为人均每天钠摄入量3563.7±1370.0mg(折合成盐9.1±3.5g)。与秋季比较,夏季人均尿钠减少约520.7mg(折合成盐1.3g)。2.各方法与金标准的一致性与相关性分析从群体水平上看,夏季INTERSALT法对上午尿进行估测的偏差最小,平均偏差值(估计值-实测值)为-39.7mg/天;膳食调查法的总平均偏差最小,平均偏差值为42.7mg/天。秋季Tanaka法对上午尿进行估测的偏差最小,偏差均值为-149.8mg/天;Kawasaki法总平均偏差最小,平均偏差值为163.7mg/天。从个体水平上看,24小时尿钠排泄量与膳食调查法测得的钠摄入量的相关性较低,相关系数仅为0.123,与Kawasaki法、INTERSALT法、Tanaka法三种方法的相关系数在0.52-0.64之间,夏季Kawasaki法的相关系数最高,为0.612;秋季Tanaka法的相关系数最高,最高系数为0.635。结论:1.由于气温原因,夏季排汗较多,用时点尿或24h尿液收集法估测膳食钠的摄入量偏差较大,若用尿液收集法,最好避开夏季。2.膳食调查法和Kawasaki法、INTERSALT法、Tanaka法三种方法估算大学生的钠摄入量均存在不同程度的偏差和波动性,但本研究只是部分人群的分析,需要更多研究来验证,同时需要制定一个适合中国人群的估算钠摄入量的方法,从而更准确地估计中国人群的食盐摄入量。3.所调查大学生的控盐意识不足,应加强营养宣传教育。
