Association of Diet Quality with Hand Grip Strength Weakness and Asymmetry in A Multi-ethnic Asian Cohort

This study aims to investigate the association of diet quality with HGS weakness and asymmetry in a multi-ethnic population in Singapore. This cross-sectional study used data from the Singapore Multi-Ethnic Cohort (n=1,547). Dietary data were collected using a validated semi-quantitative food frequency questionnaire and summarized as the Dietary Quality Index - International (DQI-I). HGS was calculated as the maximum value of six measurements from both hands. HGS weakness and asymmetry were defined using well-recognized criteria. Multivariable linear regression and logistic regression were utilized for continuous and binary outcomes respectively, adjusting for age, sex, ethnicity, physical activity, and smoking status. It was found that the highest quartile of DQI-I was significantly associated with higher HGS (β=1.11; 95%CI: 0.41, 1.82; p-trend<0.001), and lower odds of HGS asymmetry (OR=0.71; 95%CI: 0.53, 0.94; p-trend=0.035) and both HGS weakness and asymmetry (OR=0.50; 95%CI: 0.32, 0.76; p-trend=0.004). Among the different components of DQI-I, only dietary adequacy was significantly associated with higher HGS (p-trend<0.001) and lower odds for both HGS weakness and asymmetry (p-trend=0.006). Our findings support that DQI-I, an indicator of overall diet quality, can be used to provide dietary guidelines for prevention and management of muscle wasting, sarcopenia, and frailty.PMID:37990416 | DOI:10.1017/S0007114523002647
