目的统计乐昌市2016年五所小学8~10岁儿童、县城和乡(镇)两区孕妇尿碘及盐碘水平及其分布。方法采用分阶整群抽样方法选定乐昌市的乐城二小、梅花小学、金鸡小学、廊田小学、九峰小学的8~10岁学生共计207人;乐城孕妇、乡镇孕妇共计110人,采集尿样检测尿碘、收集家中食用盐检测碘含量。结果检测学龄儿童207份尿样及食盐(男生118份,女生89份),调查对象尿碘中位数316.1μg/L(男生为311.6μg/L,女生为320.4μg/L),盐碘平均含量为27.4mg/kg;孕妇110份尿样及食盐(县城为57人,乡(镇)为53人),尿碘中位数为262.5μg/L(县城为219.3μg/L,乡镇为281.4μg/L),盐碘平均含量为25.4 mg/kg。结论学龄儿童的尿碘中位数值偏高,为316.1μg/L,大大超过儿童适宜尿碘中位数100~199μg/L,为过量碘摄入;尿碘中位数乡(镇)孕妇为281.4μg/L,大于县城孕妇的219.3μg/L,均为超足量碘摄入。
Objective To survey urinary iodine and salt iodine levels and their distribution in pregnant women in 8 primary schools, 10 towns and townships (towns) in two primary schools in Lechang City in 2016. Methods A stratified cluster sampling method was used to select 207 students aged 8-10 in Lecheng Second Primary School, Meihua Primary School, Jinji Primary School, Jintong Primary School and Jiufeng Primary School in Lecheng City. Pregnant women and pregnant women in towns totaling 110 People, urine samples collected urine iodine, salt collected at home to detect iodine content. Results A total of 207 urine samples and salt samples from school-aged children (118 boys and 89 girls) were tested. The median urinary iodine was 316.1 μg / L (311.6 μg / L for boys and 320.4 μg / L for girls) The content of urinary iodine was 27.4mg / kg; 110 urine samples and salt of pregnant women (57 in county and 53 in township); the median urinary iodine was 262.5μg / L (219.3μg / L in county and 281.4 μg / L), the average salt iodine content was 25.4 mg / kg. Conclusions The urinary iodine median of school-age children is 316.1μg / L, which is much higher than the median urinary iodine of 100 ~ 199μg / L in children, which is the excess iodine intake. The median urinary iodine 281.4μg / L, 219.3μg / L more than the number of pregnant women in the county.
