浙江舟山渔区糖尿病流行病学调查

SURVEY OF DIABETES MELLITUS IN A FISHING AREA OF ZHOUSHAN ZHEJIANG

目的：了解浙江舟山渔区糖尿病（ＤＭ）患病率。方法：１９９４年２月～３月间对舟山地区２个渔村进行糖尿病（ＤＭ）普查。调查人数１０００人（男４７３人、女５２７人），年龄２５岁～６４岁，总受检率占同年龄段当地人口的９０５％。对其中餐后２ｈ血糖≥６６７ｍｍｏｌ／ｄｌ的９０例，做口服７５ｇ葡萄糖耐量试验。结果：发现ＤＭ１６例，标化后患病率为１０３％；糖耐量减低２５例，标化后患病率为２１１％，均低于１９９４年全国普查结果（分别为２５１％和３２％）。结论：ＤＭ患病率低的原因可能与渔民长期海上作业体力活动强及饮食多为海鱼类食物有关。
