Household Head Smoking Behavior and Household Food Insecurity in South Africa: Evidence from National Income Dynamics Study Survey

Abstract

This study examines how the smoking behavior of household head impacts the food insecurity status of household in South Africa, with a focus on smoking behavior transition. The study used the fifth wave of the 2017 National Income Dynamics Study survey. Additionally, the smoking transition variable was computed using smoking status in waves 3 and 5 of the survey. Foster-Greer-Thorbecke food insecurity index, descriptive statistics, and logit regression techniques were deployed in the study. Surprisingly, the analysis shows that households headed by current smokers have a lower prevalence of food insecurity (compared to households whose heads are nonsmokers). Similarly, household food insecurity prevalence is lesser for homes whose head initiated smoking behavior or remained a smoker compared to those whose head remained a nonsmoker or transition to nonsmoking. Nevertheless, the findings from the applied logit regression suggested that household food insecurity significantly increases when a household head is a current smoker and a consistent smoker. The finding indicates that household head smoking behavior does contribute to household food insecurity in South Africa. The need to address food insecurity at the household level is a compelling argument for tobacco smoking cessation or control in addition to health consequence concerns.
