Drivers and solutions to unhealthy food consumption by adolescents in urban slums in Kenya: A qualitative participatory study

Abstract

Objective:

To explore the perceptions, drivers, and potential solutions to 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 in adolescents living in urban slums, Kenya.

Design:

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

Setting:

Three major slums, Nairobi.

Participants:

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

Results:

UPF/HFSS consumption emerged as a predominant theme on the causes of undernutrition and overweight/obesity and foods commonly consumed by adolescents. Adolescents described UPF/HFSS as junk, oily, sugary or foods with chemicals, and associated UPF/HFSS consumption with undernutrition, obesity, non-communicable diseases. They perceived UPF/HFSS as modern, urban, classy, appealing to young people, and minimally processed foods as boring, 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, 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 adverse effects of consuming UPF/HFSS, through existing structures (youth groups, school, community health strategy) was proposed as potential solution to UPF/HFSS consumption.

Conclusion:

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 address the underlying perceptions and drivers of UPF/HFSS consumption at individual-level, and social and physical food environments.
