Abstract:
Objective? To explore the correlation among muscle strength, muscle mass, muscle function and cognitive function of old people in a community in Beijing. Methods? From April 2018 to October 2018, we selected 192 elderly people aged 60 or over in a community in Beijing. Muscle strength was evaluated with the CAMRY electronic handgrip strength instrument EH101; mass of limb skeletal muscle was measured with body fat scale to calculate the relative skeletal muscle index (RSMI) of limbs; muscle function was measured with the 4-m walk test; cognitive function was assessed with the Mini-Mental State Examination (MMSE). SPSS 20.0 was used to data statistics. Results? Among 192 subjects, the incidences of mild and medium cognitive impairment were 65.62%(126/192) and 12.50%(24/192) respectively. Spearman correlation analysis showed that muscle strength, muscle mass and muscle function had correlations with cognitive function with statistical differences (r=0.384, 0.215, 0.458;P＜ 0.05). Muscle strength and muscle mass had strong statistical correlations with attention of cognition (r=0.319, 0.229;P＜ 0.05). Muscle function had strong statistical correlation with linguistic competence (r=0.392, P＜0.05). Muscle strength, muscle mass and muscle function all had correlations with attention as well as linguistic competence with statistical differences (P＜0.05). Taking whether cognitive function was normal or not as dependent variable, Logistic regression analysis showed that the influencing factors of cognitive function were ages, body mass index (BMI), body fat rate and RSMI. Conclusions? Muscle strength, muscle mass and muscle function had positive correlations with cognitive function among elderly people.
