摘要
目的了解衡水市孕妇碘营养状况,为衡水市调整重点人群碘缺乏病防治策略提供依据。方法采用横断面调查方法,2017-2023年在衡水市各碘缺乏县(市、区)每年抽取100名孕妇,采集一次随机尿样及家庭食用盐盐样,测定尿碘及盐碘含量,对孕妇碘营养状况进行评价并分析影响因素。结果累计检测6570份孕妇尿样,总体尿碘中位数为158.5μg/L,尿碘<150μg/L的孕妇占总人数的46.0%(3022/6570)。不同年份间孕妇尿碘中位数比较,差异有统计学意义(H=51.52,P<0.001);不同年龄组孕妇尿碘中位数和频数分布比较,差异均无统计学意义(Z=-1.34,P=0.181;χ^(2)=1.35,P=0.717);不同孕期孕妇尿碘中位数比较,差异有统计学意义(H=10.61,P=0.005),其中孕早期尿碘中位数高于孕晚期(P<0.05)。Spearman秩相关分析结果显示,孕妇尿碘含量与食用盐碘含量呈正相关(r=0.08,P<0.001)。结论衡水市孕妇碘营养水平总体达到推荐适宜水平(150~249μg/L),但部分孕妇仍存在碘营养不足的风险。应加强关注,做好孕妇孕期的补碘工作。
Objective To investigate the iodine nutritional status of pregnant women in Hengshui City,so as to provide a basis for adjusting the prevention and control strategies of iodine deficiency disorders in key populations in Hengshui City.Methods Using a cross-sectional survey method,100 pregnant women were randomly selected from iodine deficient counties(cities,districts)in Hengshui City from 2017 to 2023 each year.Random urine samples and household salt samples were collected once a year to measure urine iodine and salt iodine levels.The iodine nutritional status of pregnant women was evaluated and influencing factors were analyzed.Results A total of 6570 urine samples from pregnant women were tested,with a median urinary iodine level of 158.5μg/L.Pregnant women with urinary iodine levels below 150μg/L accounted for 46.0%of the total population(3022/6570).There was a statistically significant difference in the median urinary iodine levels among pregnant women in different years(H=51.52,P<0.001),but there was no statistically significant difference in the median and frequency distribution of urinary iodine among pregnant women in different age groups(Z=-1.34,P=0.181;χ^(2)=1.35,P=0.717).There was a statistically significant difference in the median urinary iodine levels among pregnant women during different stages of pregnancy(H=10.61,P=0.005),with the median urinary iodine levels in early pregnancy being higher than those in late pregnancy.Spearman rank correlation analysis results showed that the urinary iodine level of pregnant women was positively correlated with the edible salt iodine level(r=0.08,P<0.001).Conclusions The overall iodine nutrition level of pregnant women in Hengshui City has reached the recommended adequate level(150-249μg/L),but some pregnant women still face the risk of iodine deficiency.We should pay more attention and do a good job in supplementing iodine for pregnant women during pregnancy.
