Abstract:
Objective:To learn about the implementation of various prevention and control measures after achieving the stage goal of eliminating iodine deficiency disorders (IDD) in Fuzhou City, and to evaluate the prevention and control effect.Methods:In September 2020, an assessment and evaluation was conducted on elimination of IDD in 12 counties (cities, districts) under the jurisdiction of Fuzhou City, with specific reference to the "Evaluation Content and Judgment Standards for Elimination of Iodine Deficiency Disorders" (2019 version). Using the target evaluation table for eliminating IDD, 4 management indicators of organizational and leadership, monitoring and prevention measures, iodized salt management and health education in 12 counties (cities, districts) from 2016 to 2020 were evaluated. Using stratified random sampling method, 2 townships/streets were selected from each county (city, district), and 20 pregnant women were sampled from each township/street. At the same time, two villages (neighborhood committees) were randomly selected from each township/street, and 20 children aged 8 - 10 (age balanced, half male and half female) were randomly selected from each village (neighborhood committee). The edible salt samples and instant urine samples of children and pregnant women were collected to detect the contents of salt iodine and urinary iodine; the iodine supplementation status of pregnant women was investigated by iodine supplementation rate questionnaire; the goiter in children was measured by B-ultrasound.Results:The management indicators scores of all 12 counties (cities, districts) were > 85 points, with an average score of 92.75 points. Changle District had the highest score (98 points), and Taijiang District had the lowest score (90 points). A total of 1 457 household salt samples were collected and tested in the city, including 967 samples from children aged 8 - 10 and 490 samples from pregnant women. The median salt iodine was 24.24 mg/kg, and the coverage rate of iodized salt was 93.62% (1 364/1 457). The qualified rate of iodized salt was 97.80% (1 334/1 364), and the coverage rate of qualified iodized salt was 91.56% (1 334/1 457). Except for Gulou District (88.33%, 106/120), Taijiang District (85.00%, 102/120), Mawei District (86.67%, 104/120), Changle District (89.34%, 109/122) and Minqing County (88.43%, 107/121), the coverage rate of qualified iodized salt was < 90%, the coverage rate of qualified iodized salt in the remaining counties (cities, districts) was > 90%. A total of 967 urine samples were collected from children, the median urinary iodine was 187.80 μg/L. The median urinary iodine of children in all counties (cities, districts) ranged from 140.08 to 269.70 μg/L. A total of 967 children were examined, and the goiter rate was 0.72% (7/967). The goiter rate ranged from 0 to 2.44% in all counties (cities, districts). A total of 490 urine samples were collected from pregnant women, with a median urinary iodine of 148.48 μg/L. Among them, the median urinary iodine of pregnant women in Gulou District (184.23 μg/L), Mawei District (262.85 μg/L), Jin'an District (176.80 μg/L), Luoyuan County (166.60 μg/L) and Yongtai County (157.62 μg/L) was > 150 μg/L, the median urinary iodine of pregnant women in other counties (cities, districts) was between 100 and 150 μg/L. A total of 490 pregnant women were investigated for iodine supplementation, the iodine supplementation rate was 94.90% (465/490). Except for Gulou District (85.00%, 34/40), Cangshan District (85.00%, 34/40) and Lianjiang County (87.50%, 35/40), the iodine supplementation rate < 90%, the iodine supplementation rate of pregnant women in other counties (cities, districts) was > 90%.Conclusions:The IDD prevention and control measures in Fuzhou City have been well implemented, and all counties (cities, districts) in Fuzhou City have maintained the state of eliminating IDD, and continued to consolidate the prevention and control achievements.
