目的掌握宁波市江东区社区居民急性胃肠炎的患病及诊疗情况,为急性胃肠炎防控提供理论依据。方法 2013年8月至2014年7月采用入户问卷方式对选定的社区居民过去4周急性胃肠炎发病情况开展调查,统计患病率、发病率,同时对不同水平进行比较。采用SPSS 17.0软件,患病率比较采用χ2检验或Fisher精确概率法,P<0.05为差异有统计学意义。结果本次调查共收回问卷2 400份,发生急性胃肠炎56例,人口标化后4周患病率为2.54%;年发病率为0.33次/人年。不同月份之间急性胃肠炎的患病率差异有统计学意义(χ2=54.831,P<0.05),其中8月患病人数最多。各季节间患病率差异有统计学意义(χ~2=45.344,P<0.05),秋季患病率高于其他季节。不同年龄组间患病率差异有统计学意义(P<0.05);家庭人口≥3人家庭与1~2人家庭的急性胃肠炎患病率差异有统计学意义(χ~2=4.070,P<0.05);急性胃肠炎患者中食源性的比例为64.29%,主要可疑食物为动物性食物,获取食物的地点主要在家中;急性胃肠炎的就诊率32.14%(18/56),药物使用率67.86%(38/56)。结论宁波市江东区急性胃肠炎的流行状况与国内外其他地区的共同点:发病率较高、低龄人群为高危人群、秋季是高发时段、食源性比例较高;不同点:果蔬及水产品是急性胃肠炎的重要媒介,就诊率偏低。 Objective To investigate the prevalence and diagnosis and treatment of acute gastroenteritis among community residents in Jiangdong District, Ningbo City, and to provide a theoretical basis for prevention and control of acute gastroenteritis. Methods From August 2013 to July 2014, the incidence of acute gastroenteritis in the selected community residents in the past 4 weeks was investigated by using the household questionnaire. The prevalence and morbidity were calculated and compared at different levels at the same time. Using SPSS 17.0 software, the prevalence was compared using χ2 test or Fisher exact test, P <0.05 was considered statistically significant. Results A total of 2 400 questionnaires were collected and 56 cases of acute gastroenteritis were recalled in this survey. The prevalence rate was 2.54% at 4 weeks after population standardization. The annual incidence rate was 0.33 times per person. The prevalence of acute gastroenteritis among different months was statistically different (χ2 = 54.831, P <0.05), with the highest prevalence in August. The prevalence among different seasons was statistically significant (χ ~ 2 = 45.344, P <0.05), and the prevalence in autumn was higher than that in other seasons. There were significant differences in the prevalence rates among different age groups (P <0.05). The prevalence of acute gastroenteritis in families with ≥3 family members and those with 1-2 family members was significantly different (χ ~ 2 = 4.070, P <0.05). The prevalence of acute gastroenteritis was 64.29%. The main suspicious food was animal food, and the main place for food was at home. The visiting rate of acute gastroenteritis was 32.14% (18/56) , Drug use rate of 67.86% (38/56). Conclusions The epidemic situation of acute gastroenteritis in Jiangdong District of Ningbo City is in common with that of other regions at home and abroad. The prevalence rate is high, the low-aged population is high-risk population, the high incidence period is high in autumn, and the proportion of food source is high. The differences are: fruits and vegetables and water The product is an important medium of acute gastroenteritis, the visiting rate is low.
