【摘要】 [目的]了解福建省城市学龄儿童的智力发育水平及影响因素。[方法]用中国联合型瑞文测验(CRT C2)测 定我省不同城市儿童智商(IQ)。[结果]我省城市儿童智商平均水平为102.4±14.6,轻度智力落后的患病率仅为1.7%; 不同城市之间儿童智力发育水平和轻度智力落后的患病率差异有显著性;沿海城市儿童的平均智商高于山区儿童,二者 轻度智力落后的患病率分别为1.1%和2.5%;不同年龄间儿童的智商差异有显著性,不同性别间儿童智商则类似;非碘 缺乏病区的城市儿童,平均智商高于碘缺乏病区,居住在碘缺乏重病区的儿童,轻度智力发育落后的患病率高于居住在 碘缺乏轻病区和非碘缺乏病区。[结论]我省儿童智力发育水平正常,影响城市儿童智力发育的主要因素是当地碘营养 状况和社会经济文化水平。更多还原
