Developing healthy eating habits in adolescence are foundations for good health in adulthood.
Many boys and girls in developing countries enter adolescence undernourished, making them more
vulnerable to disease and early death. At the other end of the spectrum, the number of
adolescents who are overweight or obese is increasing in low-, middle- and high-income
countries.
Physical activity provides fundamental health benefits for adolescents, including improved
cardiorespiratory and muscular fitness, bone health, maintenance of a healthy body weight, and
psychosocial benefits. WHO recommends for adolescents to accumulate at least 60 minutes of
moderate- to vigorous-intensity physical activity daily,
Globally, only 1 in 5 adolescents are estimated to meet these guidelines.
