Abstract:
Objective To find out the prevalence of iodine deficiency disorders (IDD) and population iodine nutritional status,and to evaluate the intervention effect of iodized salt during the Twelfth Five-Year Plan period,and to provide a scientific basis for adjusting the intervention programs.Methods One town was selected respectively from the east,the west,the south,the north and the central of the entire city,4 villages were selected from each town,15 residents were selected to determine iodide content by quantitative detection;1 primary school was selected respectively from those 5 chosen towns,40 subjects aged from 8 to 10 years old (half male and half female) in each school were selected to collect urine samples for determination of urinary iodine,and to detect the volume of thyroid by palpation;20 pregnant women were chosen respectively from those 5 towns to detect their urinary iodine content and to determine iodine content of their salt samples,10 pregnant women were selected to investigate their healthy knowledge.Results A total of 300 samples of edible salt were tested,the median of salt iodine was 21.2 mg/kg,coverage rate of iodized salt was 97.7％ (293/300),the consumption rate of eligible iodized salt at household level was 90.3％ (271/300);the median of urinary iodine level was 232.4 μg/L in 200 8-10 years old chindren;232.9 μg/L in 100 pregnant women;the prevalence rate of goiter in children aged 8-10 was 3.0％ (6/200);the healthy knowledge rate of pregnant women was 82.0％ (41/50).Conclusions During the Twelfth Five-Year Plan period,Zaoyang has achieved the stage of elimination of IDD,but the situation of iodine nutritionrich children and the iodine nutrition-lack pregnant women are still exist.Therefore,we still need to strengthen the salt market management and insist to spread the knowledge of IDD,to eliminate the non-iodized salt from the market,and to ensure all people in appropriate iodine nutrition.
