Abstract

The study aimed at determining whether there is an association between paternal smoking and nutritional status of children aged 0-59 months. Furthermore, the study looked at the presence of any nutritional differentials within different socio-economic groups. Secondary analysis of data on children aged 0-59 months enrolled in the Hospital Surveillance System of International Centre for Diarrhoeal Disease Research, Dhaka Hospital, Bangladesh, during 1996-2006. Among 13,555 under-five children, fathers of 49% were smokers. In multivariate logistic regression models adjusting for potential confounders, fathers' smoking was significantly associated with increased risk of moderate underweight (OR 1.16, 95% CI 1.08-1.25), severe underweight (OR 1.15, 95% CI 1.06-1.26), moderate stunting (OR 1.15, 95% CI 1.06-1.23) and severe stunting (OR 1.13, 95% CI 1.03-1.25). In middle and lower socio-economic strata, risk of moderate and severe child malnutrition was found to be significantly increased in the group where the father was a smoker. Results indicate that there is an association between fathers' smoking and malnutrition of under-five children particularly in lower socio-economic group. A possible mechanism - if this association is causal - may be through a negative effect on family economy.
