简要总结
Despite the acknowledgment that physical activity is important for health, there are still few population-based or school-based studies that uses the current physical activity guidelines for adolescents.
Physical inactivity was defined a less than 300 min/w of moderate to vigorous-intensity physical activity practice.
Previous research has shown very high prevalence rates of physically inactive adolescents and a strong association with demographic, socioeconomic and biological factors.
Based on this information, the investigators are elaborating a systematic review of literature to obtain and provide more accurate information in this context.
详细描述
The objectives of this study were to (i) review extant literature on the prevalence of physical inactivity (PI) in adolescents of both sex (10-18 years old); (ii) compare its prevalence between developed and developing countries.
