Drivers and solutions to unhealthy food consumption by adolescents in urban slums, Kenya: a qualitative participatory...

To explore the perceptions, drivers and potential solutions to the consumption of unhealthy, ultra-processed foods (UPF) and foods high in fat, salt and sugar (HFSS) and their contribution to the double burden of malnutrition among adolescents living in urban slums, Kenya.

Qualitative participatory research, through Photovoice, group discussions and community dialogues. Inductive, thematic analysis was undertaken.

Three major slums, Nairobi.

Adolescents 10-19 years (n 102: 51 boys, 51 girls) and adults (n 62).

UPF/HFSS consumption emerged as a predominant theme on foods commonly consumed by adolescents, and the causes of undernutrition and overweight/obesity. Adolescents described UPF/HFSS as junk, oily, sugary or foods with chemicals and associated UPF/HFSS consumption with undernutrition, obesity and non-communicable diseases. They perceived UPF/HFSS as modern, urban, classy and appealing to young people and minimally processed foods as boring and primitive, for older people, and those in rural areas. Individual-level drivers of UPF/HFSS consumption were organoleptic attributes (taste/aroma), body size/shape, illicit drug use, convenience and adolescents' autonomy. Social environment drivers were peer pressure and social status/aspirations. Physical environment drivers were UPF/HFSS availability and accessibility in the slums. Education on healthy eating and the adverse effects of consuming UPF/HFSS, through existing structures (youth groups, school, community health strategy), was proposed as a potential solution to UPF/HFSS consumption.

UPF/HFSS were perceived as associated with poor nutrition and health, yet were preferred over unprocessed/minimally processed foods. Interventions to promote healthy diets beyond raising awareness are important, while addressing the underlying perceptions and drivers of UPF/HFSS consumption at the individual level and in the social and physical food environments.
