This study aims to identify risk factors associated with episodes of diarrhea among infants under six months from the Southern Zona da Mata region in the State of Pernambuco, Brazil. This was a case-control study nested in a cohort. A total of 397 infants were studied, with 239 infants classified as cases and 158 as controls (1.5:1). Odds ratios (OR) and 95% confidence intervals were calculated. Logistic regression analysis was conducted to identify predictive factors for the outcome, showing that lack of piped water in the house (OR = 3.60; 95% CI 1.49-8.74) and duration of breastfeeding less than six months (OR = 2.06; 95% CI 1.26-3.38) were the significant risk factors associated with occurrence of diarrhea, after adjusting for other variables.
本研究旨在确定巴西伯南布哥州南马塔地区六个月以下婴儿腹泻发作的相关风险因素。这是一项嵌套在队列研究中的病例对照研究。共对397名婴儿进行了研究，其中239名婴儿被归类为病例，158名作为对照（比例为1.5:1）。计算了优势比（OR）和95%置信区间。进行逻辑回归分析以确定该结果的预测因素，结果显示，在对其他变量进行调整后，家中无自来水（OR = 3.60；95% CI 1.49 - 8.74）以及母乳喂养持续时间少于六个月（OR = 2.06；95% CI 1.26 - 3.38）是与腹泻发生相关的显著风险因素。
