Purpose: This study aimed at exploring food related cultural norms that influence rural mothers' food selection for their primary school aged children (aged 4-7 years). Design/methodology/approach: This is a qualitative study conducted in northern parts of Balochistan province of Pakistan. The Theory of Planned Behaviour (TPB) was applied as the theoretical framework of the study. Within a qualitative research method four focused group interviews with 30 rural mothers were employed to generate data. Findings: The study found that mothers' food selection for their children was heavily influenced by certain cultural norms that have become taboos with the passage of time. It is evident through findings that subjective norms have a greater influence on mothers' behaviour than their attitude and perceived behavioural control (PBC). Originality/value: We ensure originality of this research paper as fewer researches have been conducted to further elaborate the link between socio-cultural norms and food selection. In particular, the influence of this close relationship on child health has been of limited consideration in a developing context. This paper has neither been published elsewhere, nor it is currently under consideration for publication in any other journal.
