Paternal smoking is associated with increased risk of child malnutrition among poor urban families in Indonesia

Abstract

Objective: Paternal smoking is highly prevalent in Asia, and tobacco may account for a large proportion of household expenditures among poor families. We sought to characterise the relationship between paternal smoking, child malnutrition and food expenditures. Design: Data on smoking, household expenditures and child malnutrition were examined in a stratified multistage cluster sample of households in the Indonesia nutrition surveillance system. Main outcome measures were child wasting (weight-for-height Z-score < 0.0001), severe wasting (OR = 1.17, 95% CI 1.03-1.33, P = 0.018) and severe stunting (OR = 1.09, 95% CI 1.04-1.15, P < 0.001). In households where the father was a smoker, tobacco accounted for 22% of weekly per capita household expenditures, with less money spent on food compared with households in which the father was a non-smoker. Conclusions: Among poor families in urban slum areas of Indonesia, paternal smoking diverts household money from food to tobacco and exacerbates child malnutrition. © 2007 The Authors.
