Influences of psychosocial factors and home food availability on healthy meal preparation.

The involvement of children in healthy meal preparation activities has emerged as a potential strategy to promote healthy eating behaviour among children. However, there is a lack of understanding of children's internal (psychosocial factors) and external factors (home food availability) that may support the practice of preparing healthy meals. This study aimed to determine children's psychosocial factors of healthy meal preparation within themselves and their external environment of home food availability as predictors for the practice of healthy meal preparation. Public schools (n = 8) from all three zones (Bangsar-Pudu, Keramat and Sentul) in Kuala Lumpur, Malaysia, were selected through stratified random sampling. Two hundred children aged 9-11 and their parents participated. Children's psychosocial factors towards healthy meal preparation and their home food availability were assessed through children and parents, respectively, using validated questionnaires. Majority of the schoolchildren (86.5%) had poor practice of healthy meal preparation. Increased attitude (r = 0.344, P < 0.001) and self-efficacy (r = 0.501, P < 0.001) of healthy meal preparation and the availability of fruits (r = 0.304, P < 0.001), vegetables (r = 0.243, P < 0.001) and healthful ready-to-eat foods (r = 0.227, P = 0.001) at home were positively correlated with the practice of preparing healthy meals. After adjusting for age, sex and monthly household income, increased self-efficacy (P < 0.001), availability of fruits (P = 0.01) and lower availability of less healthful ready-to-eat food (P = 0.01) were associated with better healthy meal preparation practices. Outcomes revealed that positive self-efficacy of healthy meal preparation, home food availability of fruits and less healthful alternatives were associated with the practice of healthy meal preparation and thus should be targeted in future health-promotion strategy.
