To perform a systematic review of crosssectional studies on the prevalence of insufficient physical activity (IPA) based on a WHO-defined cutoff point (< 60 min/d of moderate and vigorous physical activity).
The search was carried out using online databases (BioMed Central, CINAHL, EMBASE, ERIC, PsycInfo, PubMed MEDLINE, SCOPUS, SPORTDiscus), and included articles published from the beginning of the databases until February18th, 2012, as well as references cited by the retrieved articles and information provided by the authors. Only original articles using questionnaires in the diagnosis were considered.
Of 2,384 papers initially retrieved, fifteen studies met the inclusion criteria, of which seven were conducted in Brazil. The prevalence of IPA varied from 18.7% to 90.6%, with a median of 79.7%. In all surveys, the prevalence was higher among girls than boys and the developing countries have higher prevalence.
We concluded that the prevalence of IPA is high among adolescents and that the definition adopted in this study is rarely used in the literature. These results suggesting that is necessary the development of interventions for increasing physical activity levels among adolescents.
基于世界卫生组织定义的临界点（中度和剧烈身体活动每天少于60分钟），对身体活动不足（IPA）患病率的横断面研究进行系统综述。
使用在线数据库（生物医学中心、护理学与健康领域数据库、医学与健康领域数据库、教育资源信息中心、心理学文摘数据库、医学期刊数据库、Scopus数据库、体育文献数据库）进行检索，纳入从各数据库创建之初至2012年2月18日发表的文章，以及检索到的文章所引用的参考文献和作者提供的信息。仅考虑在诊断中使用问卷的原创文章。
最初检索到2384篇论文，其中15项研究符合纳入标准，其中7项在巴西进行。IPA的患病率从18.7%到90.6%不等，中位数为79.7%。在所有调查中，女孩中的患病率高于男孩，发展中国家的患病率更高。
我们得出结论，青少年中IPA的患病率很高，且本研究采用的定义在文献中很少使用。这些结果表明有必要制定干预措施以提高青少年的身体活动水平。
