热带气候对海南省小儿腹泻影响的研究

A STUDY ON THE INFLUENCE OF THE TROPICAL CLIMATE TO CHILDREN DIARRHEA OF HAINAN PROVINCE

目的：探讨热带气候对海南省小儿急性腹泻的影响因素及发病规律。方法：1997年度在海南省东西南北中及海口市各设一个监测点对5岁以下小儿1654人进行腹泻流行病学调查．采用每月三日法。并将腹泻月平均发病率与相应月份气象指标进行相关分析。结果：月平均发病率20．19％，年发病率为242．29％。平均每人每年腹泻发病次数为2．42±0.08，年死亡率0．60％，发病高峰在1～3月份，与气温、雨量呈显著负相关。结论：海南省1～3月份发病率高其原因与该季节温度低，雨量少气候环境影响有关。

Purpose Investigate the influencefactor of the tropical climate to children acute diarrhea of Hainan province and the law of thisolisease, Method In 1997 an observation site wasrespectively set up in the east, south, west, northand middle parts of Hainan province and Haikoucity to make an investigation on diarrhea epidemiology of 1654 children under five years, this wasdone three days a month.
