摘要
目的了解合肥市城乡孕妇碘营养状况,为孕妇孕期补碘提供科学依据。方法整群抽样方法抽取合肥市包河区和长丰县罗塘镇为调查点,采用方便抽样方法抽取孕妇,了解孕妇碘营养情况,对碘盐合格率、水碘浓度、尿碘浓度以及促甲状腺激素(thyroid stimulating hormone,TSH),游离甲状腺素(free thyroxine,FT4),游离三碘甲状腺原氨酸(free triiodothyronine,FT3),总甲状腺素(total thyroxine,TT4)和总三碘甲状腺原氨酸(total-triiodothyronine,TT3)等指标进行分析。结果调查显示碘盐合格率城区98.1%、农村97.9%;水碘浓度城区中位数分别为4.5μg/L、农村10.3μg/L,2组差异有统计学意义;尿碘浓度中位数为161.8μg/L,总体水平偏低,其中城区142.5μg/L,农村196.5μg/L,2组差异有统计学意义;FT4、TT4和TT3显示城区与农村之间差异有统计学意义。Logistic回归分析显示中重强度的体力劳动和经常吃海产品是碘营养高于适宜水平的危险因素。结论合肥市城乡孕妇碘营养总体水平不良,其中43.8%的孕妇处于不足水平,24.5%的孕妇处于超适宜水平,应引起高度重视。总体看农村碘营养水平稍好于城区。
Objective To explore the iodine nutritional status among pregnant women in rural and urban areas of Hefei, and provide scientific evidence for iodine intake among pregnant. Methods Iodine nutritional status of pregnant in Changfeng County （100） and Baohe District （108） were collected by the ways of cluster sampling. The rate of qualified io- dized salt, water iodine content, urine iodine concentration, thyroid stimulating hormone（TSH）, free thyroxine（ FT4 ）, free triiodothyronine （ F13 ）, total thyroxine （ Tf4 ） and total-triiodothyronine （ TY3 ） were analyzed. Results The rates of qual- ified iodized salt were 98.1% in urban, and 97.9% in rural. The median of the water iodine content were 4. 5p^g/L in ur- ban area, and 10. 3p^g/L in rural area. There was significant difference between urban and rural areas. The median of urine iodine concentration was 161.8 p^g/L in all case. The general level of urine iodine concentration was low. The median of u- rine iodine concentration were 142. 5 p,g/L in urban area, and 196. 5 txg/L in rural area. There was significant difference between urban and rural areas. The significant differences were found in FT4, TT4, and TF3 between the two groups. The results of Logistic regression showed that heavy manual labor and eat seafood occasionally were two influencing factors, which were related to optimal level of iodine nutrition status. Conclusions The general level of iodine nutrition was ad- verse. 43.8% of pregnant are inadequate level and 24. 5% of pregnant in the ultra-appropriate level, which should be paid more attention. The status of iodine nutrition in rural area was better than in urban area.
