目的 调查云南省居民膳食碘摄入量,为适时调整云南省食盐加碘含量标准提供科学依据.方法 在云南省3个尿碘水平地区,每个地区抽取1个县,最终选择云南省牟定县、南涧县、梁河县作为调查县,每个调查县选取3个调查点(1个城区点和2个农村点),每个调查点选择30户居民户作为调查户,采集盐样进行盐碘测定.连续3d采用24 h膳食回顾调查法进行膳食调查,计算居民食盐摄入量、食盐碘摄入量、食物碘摄入量、总膳食碘摄入量、食盐碘摄入量对总膳食碘摄入量的贡献率.结果 共调查270户居民,每人每日食盐摄入量中位数为9.1 g;每人每日食物碘摄入量中位数为28.0μg;每人每日平均总膳食碘摄入量中位数为289.9 μg,其中正常普通人群、孕妇、哺乳期妇女每人每日总膳食碘摄入量分别为288.5、309.2、337.4 μg;0～5、6～11、≥12岁以上各年龄段人群的每人每日平均总膳食碘摄入量分别为213.0、183.8和296.7 μg.食盐碘摄入量对总膳食碘摄入量的贡献率为90.30％.结论 加碘食盐是调查地区居民膳食碘的主要来源.全民食盐加碘仍然是云南省今后防治碘缺乏病的主要措施,但需对当前的食盐加碘含量标准进行适当下调.“,”Objectives To survey the dietary oidine intake in populations in Yunnan Province.Then to provide a scientific basis for timely adjustment of iodine concentration standard in iodized salt.Methods Yunnan Province was divided into 3 regions based on different urinary iodine levels (higher than,average,and lower than the urinary iodine level of the whole province) according to urinary iodine monitoring data of recently years; 3 counties,Mouding,Nanjian and Lianghe,were randomly sampled in the 3 regions,respectively.Then 3 sites were randomly selected (1 urban site and 2 rural sites) in each county,respectively,and 30 families were randomly selected with the method of successive 3 days 24-hour dietary retrospective in each survey site; salt intake,salt iodine intake,food iodine intake,total iodine intake and the contribution rate of salt iodine intake to total dietary iodine intake,were calculated.Results Totally 270 households were surveyed,and the median salt intake was 9.1 g per day per person; the median iodine intake through food was 28.0 μg per day per person; and the median iodine intake from total dietary was 289.9 μg per day per person.Total dietary iodine intake was 288.5 μg per day for the general population; 309.2 μg per day for pregnant women; and 337.4 μg per day for lactating women.The average iodine intake from total dietary for 0-5 years old,6-12 years old and above 12 years old was 213.0,183.8 and 296.7 μg per day,respectively.The contribution rate of salt iodine intake to total dietary iodine intake was 90.30％ in the 3 counties.Conclusions In general,the iodine intake of the population mainly comes from iodized salt in the surveyed regions.Universal Salt Iodization (USI) will still be a main measure in prevention and control of Iodine Deficiency Disorders (IDD) in Yunnan Province in the future.But the current iodine concentration in salt is unreasonable,which should be adjusted.
