Exploring the diet and physical activity behaviours of adolescents living in India and sub-Saharan Africa: a qualitative evidence synthesis.

In-depth research exploring adolescents' perceptions of diet and physical activity is needed to better understand how both boys and girls, at different stages of adolescence, perceive health, diet and physical activity. More research with young people is required especially in countries where little exists to cover a wider range of issues that play a role in diet and physical activity.
