甘肃省陇南市人群教育程度及碘营养状况与甲状腺结节的关系OA

Objective To explore the correlation between the educational level,iodine nutritional status and thyroid nodules of residents in Longnan,Gansu Province.Methods A multi-stage stratified cluster random sampling method was employed to select the Han population in Longnan,Gansu Province as the study sub-jects.Data were collected through questionnaires,urine iodine detection and ultrasound examination to ana-lyze the prevalence status of thyroid nodules under different educational levels and iodine nutritional status,and to explore the influencing factors of thyroid nodules.Results The prevalence rate of thyroid nodules among residents in this city was 18.8%,and those for men and women were 13.8%and 22.9%respectively.The prevalence rate for women was higher than that for men(P<0.05).Regarding different educational attain-ment and median urinary iodine concentration groups,with the increase of educational attainment the median urinary iodine concentration showed a gradually increasing trend,the prevalence of thyroid nodules showed a gradually decreasing trend,and the proportion of the population with abnormal thyroid function gradually de-creased(P<0.05).Among patients with thyroid nodules,47.5%had abnormal thyroid function.Among pa-tients without thyroid nodules,31.9%had abnormal thyroid function(P<0.05).Advanced age and smoking history were important influencing factors for the occurrence and development of thyroid nodules.Conclu-sion The prevalence of thyroid nodules was the highest in iodine-deficient populations and the lowest in io-dine-excessive populations in Longnan,Gansu Province.Additionally,as education level increased,the prevalence of thyroid nodules gradually decreased.
