Abstract:
Objective To investigate the iodine nutritional status of pregnant women in Jinan City,which may provide a basis for scientific supplementation of iodine.Methods Ten counties (districts) in Jinan City were divided into five areas as east,west,south,north and middle in 2018.At least one township (street) was selected from each area,and 20 pregnant women were selected from each township (street).Personal information was collected through standardized questionnaires,and household salt samples and urine samples of pregnant women were collected.Salt iodine and urinary iodine were detected by the "General Test Method in Salt IndustryDetermination of Iodine" (GB/T 13025.7-2012) and "Method for Determination of Iodine in Urine by As3+-Ce4+ Catalytic Spectrophotometry" (WS/T 107-2006),respectively.Results A total of 1 169 pregnant women's household salt samples were collected,the median of salt iodine was 22.6 mg/kg.The coverage rate of iodized salt was 90.5％ (1 058/1 169),the qualified rate of iodized salt was 75.8％ (802/1 058),and the consumption rate of qualified iodized salt was 68.6％ (802/1 169).A total of 1 169 urine samples of pregnant women were tested,the median of urinary iodine was 141.9 μg/L,indicating the urinary iodine of pregnant women was insufficient (＜ 150 μg/L).Conclusions The iodine nutrition of pregnant women is slightly inadequate in Jinan City.It is necessary to strengthen the measures in prevention and control of iodine deficiency,and promote the health education measures in pregnant women to improve their iodine deficiency status.
