Multi-component interventions to reducing unhealthy diets and physical inactivity among adolescents in sub-Saharan Africa

The fragile health systems in urban sub-Saharan Africa (SSA) are already overwhelmed with NCDs.

Despite this, the implementation of the evidence-based WHO Best Buys policies for NCDs prevention in the African region has been found to be off-track.

Additionally, less attention has been given to adolescents and yet this is a period in life where behavioural patterns of NCDs risk factors are established and track into adulthood.

There is also a gap in our understanding on how to implement and scale up effective diet and physical activity interventions in real world settings in SSA.Our project therefore aims to reduce two important modifiable risk factors for NCDs: unhealthy diets and physical inactivity and their underlying social determinants among adolescents (aged 10-19-years) living in mixed socio-economic urban communities in two SSA countries (Ghana & Kenya) by designing, deploying, and evaluating strategies for implementation of evidenced and theory based interventions mapped on to the WHO Best Buys.

We selected the two countries because they represent different cultural contexts of nutrition transition (East and West Africa), and both countries are undergoing rapid economic development, urbanisation and increases in NCD prevalence.

The intervention delivery will take a multi-sectoral approach to increasing the capability, opportunity and motivation of adolescents to eat healthier and be more physically active.

We will focus on three settings to enhance the reach: secondary schools and, family/community/faith-based settings and the digital environment using social media.

Together, this project will increase opportunities, awareness, knowledge and health literacy, motivate adolescents to increase self-efficacy, guide self-regulatory actions and adopt positive health behaviour (such as dissuasion from physical inactivity and sedentary behaviours, or unhealthy food choices) to prevent NCDs.
