目的了解新标碘盐全覆盖后厦门市城市与农村家庭食盐选择模式,为厦门市碘缺乏病防治提供科学依据。方法采用分层随机抽样方法,抽取湖里、翔安共433户家庭,调查其食盐选择模式。结果城市家庭缺碘危害知晓率(91.90%)高于农村(85.20%);城市家庭选择碘盐的比率(89.52%)高于农村(79.82%);城市家庭选择购买碘盐理由为防止碘缺乏病或对孩子智力有好处的比率(90.02%)高于农村(83.15%);城市选择始终吃加碘盐的比率(83.33%)高于农村(72.20%),选择同时吃加碘盐和不加碘盐的比率(3.33%)低于农村(9.87%);差异均有统计学意义(P<0.05)。城市与农村家庭均有超过半数家庭每周吃2次以上熟食,同时城市与农村均有约25%左右家庭每周在外就餐2次以上。结论新标碘盐全覆盖后,厦门市家庭食盐选择模式仍存在城乡差别,农村仍然是碘缺乏病防治的薄弱点,应当引起各部门重视。 Objective To understand the mode of salt selection in urban and rural families in Xiamen City after the new superseded iodized salt was completely covered so as to provide a scientific basis for prevention and treatment of iodine deficiency disorders in Xiamen. Methods A stratified random sampling method was used to extract 433 households from the lake and Xiang’an and investigate the salt selection patterns. Results The rate of iodine deficiency in urban households was 91.90% higher than that in rural areas (85.20%). The proportion of iodized salt (89.52%) in urban households was higher than that in rural areas (79.82%). In order to prevent iodine deficiency (90.02%) were higher than those in rural areas (83.15%). The rate of eating iodized salt in urban areas was always higher (83.33%) than that in rural areas (72.20% The rate of iodized salt (3.33%) was lower than that in rural areas (9.87%); the difference was statistically significant (P <0.05). More than half of urban and rural families eat cooked food more than twice a week, while about 25% of urban and rural households eat more than 2 times a week. Conclusion After the new standard iodized salt is completely covered, there is still a gap between urban and rural areas in Xiamen family salt selection mode. The rural areas are still the weak point in the prevention and control of iodine deficiency disorders and should be given the attention of all departments.
