目的了解广州市儿童感染性腹泻流行因素,为有效开展该类疾病的监测与防控提供科学依据。方法采用病例对照研究,选取545例儿童感染性腹泻患者作为病例组,并进行1:1条件匹配;采用统一设计的调查表进行调查;采用单因素和多因素条件Logistic回归分析筛选可能的危险因素。结果单因素分析差异有统计学意义(P<0.05)的变量有饭前洗手、便后洗手、零食前洗手、剪手指甲、剩饭菜放置方式、剩饭菜加热;多因素分析进入模型有统计学意义(P<0.05)的变量为饭前洗手、剪手指甲、剩饭菜的放置方式,OR值分别为0.788(95%CI=0.653～0.951)、0.715(0.575～0.890)1、.292(1.051～1.588)。结论饭前洗手、剪指甲、剩饭菜的放置与感染性腹泻的发病和流行有关,加强健康教育可以预防感染性腹泻的发生。
Objective To understand the prevalence of infectious diarrhea in children in Guangzhou and to provide a scientific basis for the effective prevention and control of such diseases. Methods A case-control study was conducted. A total of 545 children with infectious diarrhea were enrolled as case group and matched with 1: 1 condition. Uniform designed questionnaire was used to investigate. Univariate and multivariate logistic regression analysis was used to screen possible risk factors . Results The univariate analysis showed that there were significant differences between the two groups (P <0.05). The variables were hand-washing before meals, hand-washing after hand-washing, hand washing before snacking, The statistical significance (P <0.05) of the variables were the hand washing, cutting finger nails and leftovers before eating. The OR values were 0.788 (95% CI = 0.653-0.95) and 0.715 (0.575-0.890) 1 respectively. 292 (1.051 ~ 1.588).
