Tracking the health of Puerto Rican youth through their physical activity, fitness, nutrition and self-efficacy
Objectives
Physical activity, fitness and nutrition influence health trajectories from childhood to adulthood and are linked to the risk of chronic diseases. Despite the urgency of prevention, there is a lack of longitudinal data about these health indicators among children in Puerto Rico. This 3-year study (2013–2016) followed 46 children from ages 7 to 9 years to assess their physical activity, fitness, nutrition and self-efficacy over time, and to explore the interrelationships among these indicators.
