Abstract:
Objective:To understand the current status of overweight and obesity, the iodine nutrition level and goiter among children in Tianjin, and explore their relationships, so as to effectively adjust the prevention and control measures.Methods:From January 2019 to December 2020, one primary school was selected from all towns or streets in 16 districts of Tianjin, and non-boarding children aged 8 to 10 (age and gender balanced) were selected from each primary school. The number of children sampled in towns or streets in each district was as even as possible. Every year, 200 children from each district were investigated for height, weight, iodine of household edible salt, urinary iodine and thyroid volume. Body mass index (BMI) was calculated and its relationship with iodine nutrition level and goiter of children was analyzed.Results:A total of 6 552 children were investigated, and the median urinary iodine was 178.95 μg/L, the goiter rate was 2.15% (141/6 552). There was no significant difference in iodine content of household edible salt among children in different BMI groups ( P = 0.835), but the difference in thyroid volume was statistically significant ( P < 0.001). By constructing a restrictive cubic spline model, the risk of goiter in children of different age groups increased with increase of BMI ( P < 0.001 or P = 0.002). Conclusions:The BMI of children is closely related to thyroid volume. The influence of height and weight should be considered in diagnosis of goiter of children.
