Abstract

Objectives: Physical activity is an important tool to combat obesity among women. The main aim of this systematic review was to identify effects of physical activity in weight reduction and weight maintenance among women.

Methods: Randomized control trials (RCT) and cohort studies published between 1997 and 2011 were searched from medical databases using MeSH keywords and predefined inclusion- exclusion criteria. CONSORT checklist and STROBE statement was used to evaluate the quality of RCTs and cohort studies. Decision upon the quality of studies and data extraction was reached up on mutual consensus between the two independent researchers.

Results: Out of a total of 168 articles, only 11 studies (7 RCTs and 4 cohort studies) were considered to be eligible for review. In general, the studies differed in methodological qualities and modes of physical activity intervention. Only three studies supported the significant effects of physical activity in weight maintenance and weight reduction among women. However, absence of effect size, absence of standardized outcome measures and presence of adjunct therapies confounds the study findings.

Conclusion: High intensity activity is the only type of physical activity that showed effects on weight maintenance and weight reduction among women. Further studies with higher methodological quality are recommended.
