Hypothesis
This study aimed to quantitatively integrate existing research on the association of protein intake with sarcopenia and related indicators in Koreans aged 65 and older through meta-analysis.
Conclusion
Lower protein intake is associated with a higher risk of sarcopenia and low hand grip strength in Korean older adults.
Supporting Evidence
- Lower protein intake is associated with a higher risk of sarcopenia.
- Protein intake of less than 0.8 g/kg/day increases the risk of low hand grip strength.
- Further well-designed RCTs are necessary to establish protein intake recommendations.
Takeaway
Eating enough protein is really important for older people to keep their muscles strong and avoid getting weak.
Methodology
The study included 23 studies, with 9 included in the meta-analysis, using fixed-effects models and performing subgroup and sensitivity analyses.
Potential Biases
Potential bias due to the inclusion of studies with different diagnostic criteria for sarcopenia.
Limitations
The diagnostic criteria for sarcopenia varied across studies, which may affect the results.
Participant Demographics
Korean older adults aged 65 and above.
