Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

The search was carried out using online databases (Biomed Central, CINAHL, EMBASE, ERIC, MEDLINE, PsycInfo, Scopus, SPORTDiscus), references cited by retrieved articles and by contact with the authors, considering articles published from the establishment of the databanks until April 29th, 2010.

Description

2137 studies retrieved in 8 databases (Biomed Central, CINAHL, EMBASE, ERIC, PsycInfo, PUBMED, SCOPUS, SPORTDiscus and uploaded in EndNote Web®.

332 studies were excluded as duplicates by EndNote Web®.

1805 titles and abstracts were assessed independently by two researchers (PG/AM): 1541 studies excluded.

264 studies referred for full-text assessment by two independent investigators (PG/AM)

225 studies were excluded according to the eligibility criteria (in case of discrepancies in the assessment of the researchers, studies were reviewed in duplicate)

39 Studies assessed for quality using STROBE

13 Studies were included in the descriptive synthesis
