Abstract

Background: Effect of protein intake on hand grip strength (HGS) is predominantly yielded using protein supplements for critically ill elderly population. In the midst of increasing chronic diseases and functional decline worldwide, we conducted a systematic review to assess the effect of dietary protein on HGS in healthy adult’s ≥ 18 years old to fill in the significant knowledge gap.

Methods: A comprehensive database search e.g. MEDLINE, EMBASE, and Cochrane Library was performed until April 2016 to assess dietary protein effect alone or with exercise. A structured data synthesis was adopted as meta-analysis of the data was not appropriate due to the wide heterogeneity in the studies.

Results: Six studies (n = 7352) were included of which only one was located in a developing country (India). Overall, studies were judged at unclear (RCT), high (intervention study), moderate (3 cohort studies), and high (one cohort study) risk of bias. We found mixed evidence on the effect of dietary protein on HGS in healthy adults. The GRADE evidence quality was moderate (trial, intervention study) and very low (cohort studies).

Conclusion: The evidence on the impact of dietary protein on HGS is inconsistent for the healthy adults. To avert globally rising functional limitations and disabilities, further investigations preferably using RCT design including healthy adults are essential.
