Risk factors for diarrhoea in preschoolers in a rural environment on the outskirts of Cape Town were evaluated using the case-control design. Methodological problems limited interpretation. Small sample size affected the precision of the results. Questionnaire-based information has shortcomings for measurement of behavioural risk factors. Despite shortcomings, positive associations with diarrhoea were suggested for use of a bottle during weaning (odds ratio 4.24, 95% confidence intervals 0.48-37.1) and small house size (odds ratio 2.13, 95% confidence intervals 0.34-5.40). Previous diarrhoea was found to be a risk factor for repeated diarrhoea.
采用病例对照设计对开普敦郊区农村环境中学龄前儿童腹泻的危险因素进行了评估。方法学问题限制了研究结果的解释。样本量小影响了结果的准确性。基于问卷的信息在测量行为危险因素方面存在缺陷。尽管存在缺陷，但研究表明，断奶期间使用奶瓶（比值比4.24，95%置信区间0.48-37.1）和房屋面积小（比值比2.13，95%置信区间0.34-5.40）与腹泻呈正相关。既往腹泻被发现是反复腹泻的一个危险因素。
