Objective
This study focused to systematically extract, summarize and analyse the data on the effect of lifestyle modification on leptin resistance and quality of life in metabolic syndrome.
Methods
The systematic search was done using PubMed, Cochrane Database, EMBASE, Science Direct, CINAHL, Springer link, Web of Science from 2000-2018. English language articles and quantitative studies focusing on leptin resistance and quality of life were included. Random effect analysis was adopted to pool data and estimate 95% CI. The meta-analysis was done separately for leptin resistance and quality of life which included a total of 9 studies on both RCTs and Non-RCTs.
Results
The meta-analysis of RCTs reported insignificant effect of lifestyle modification on leptin resistance in metabolic syndrome when compared to comparison group (-5.94(-14.28, 2.41). Two clinical trials showed a significant effect with pooled data (5.52(2.14, 8.91). Meta-analysis of RCTs focusing on quality of life showed significant effect on mental component (4.89 (0.16, 9.62) of quality of life (2.36 (-3.67, 8.39) when compared to comparison group.
Conclusion
This meta-analysis suggested that lifestyle modification has a potential to improve leptin resistance and mental component of quality of life in metabolic syndrome. However, more clearly defined studies are required to come to a stronger conclusion.
