Risk factors for overall and persistent diarrhoea in infancy in Antalya, Turkey: a cohort study.
The aim of this study was to identify factors that influence the incidence of diarrhoea in infancy. The study was a prospective cohort study conducted in two primary healthcare unit areas in Antalya, Turkey. A total of 204 infants were followed until they were aged 1 year. Morbidity surveillance and anthropometric measurements were carried out by home visits every 2 months. The average incidences were found to be 2.76 episodes per child-year for overall diarrhoea and 18.56 episodes per 100 child-years for persistent diarrhoea. Relative risks, confidence intervals and logistic regression analyses were used to assess the associations. For both overall diarrhoea and persistent episodes, increased risks were associated with having an uneducated mother (RR=1.89 and 5.33, respectively) and a self-employed father (RR=1.89 and 3.77, respectively). Among environmental factors, living in a slum was associated with both overall (RR=1.68) and persistent (RR=2.69) diarrhoea, whereas living in a crowded house (RR=1.70), having no kitchen (RR=2.27) or having an unhygienic toilet (RR=1.93) were found to be significant for overall episodes alone. Factors related to the infant were preterm birth (RR=1.64), low birth weight (RR=2.05), and first breastfeed given more than 1 h after birth (RR=1.64). Nutritional status was also associated with overall or persistent diarrhoea: underweight children (RR=2.15, persistent diarrhoea only), stunted children (RR=1.67 and 2.14, respectively) or wasted children (RR=1.54 and 3.20, respectively). By logistic regression analysis, both overall and persistent diarrhoea were found to be associated with mother's education.
