Barrier analysis for adequate daily fruit and vegetable consumption among low-income residents of Hanoi, Vietnam and Ibadan, Nigeria

Abstract Inadequate fruit and vegetable intake is a risk factor for malnutrition and non-communicable diseases, particularly in low- and middle-income countries. This study aimed to identify the determinants of daily fruit and vegetable consumption among low-income households in urban and peri-urban areas of Hanoi, Vietnam and Ibadan, Nigeria. We used the barrier analysis rapid assessment tool to assess the influence of psychosocial and individual factors and perceived characteristics of the food environment. In Hanoi, determinants were family preferences and habits, home production, and perceived benefits and action efficacy. In Ibadan, consumption was determined by affordability. Gender- and neighbourhood-related differences were found to be influential factors. As results are contextual, we recommend that interventions promoting fruit and vegetable consumption assess local determinants.
