Abstract:
Objective To analyze the present situation of iodine deficiency disorders (IDD) in Henan Province,and to promote implementation of sustainable control strategies.Methods In 2011,a stratified proportion to population probability sampling (PPS) method was used to survey 1200 children aged 8 to 10 in 30 counties of the province.One primary school was selected in each chosen county.Goiter,intelligence quotient (IQ),urinary iodine and salt iodine level were studied.Meanwhile,12 families per capita salt intake was investigated.In each school,30 5th-grade students and 30 pregnant and lactating women in the school townships and adjacent neighboring townships were selected to carry out questionnaire survey on health education with unified papers.Results ①The goiter rate of children aged 8 to 10 by B ultrasound was 4.5％ (54/1201) ; the IQ of 1080 children was 107.75 ± 16.81 ; median urinary iodine level of 358 children was 201.4 μg/L.②The median of salt iodine content was 28.6 mg/kg,the coverage rate of iodized salt was 98.8％ (1186/1200),and qualified rate of iodized salt was 93.0％ (1116/1200).③The residents average daily salt intake was 10.5 g.④Average score of the questionnaire survey of 1084 5th-grade students was 4.2 points.Average score of 961 housewives was 4.4 points.Conclusions Various technical indicators show that IDD is in a sustained elimination state in Henan Province.Strengthen health education,enhance public awareness of disease prevention is still the important work ahead.
