Association of Healthy Eating Index-2020 with muscle mass among the middle-aged individuals - a cross-sectional study based on NHANES from 2011 to 2018.

ABSTRACT:

Background

Low muscle mass exhibits a high prevalence in population, with its incidence increasing with age. Body mass index (BMI) has been identified as an independent predictor of poor muscle quality, and people with higher BMI have higher risk of low muscle mass. Nutrition interventions have been demonstrated efficacy in mitigating its effects. The Healthy Eating Index-2020 (HEI-2020) assesses overall diet quality but lacks studies on its association with low muscle mass. This study aims to investigate the association between the HEI-2020 and low muscle mass and to explore the mediating role of BMI among middle-aged individuals.

Methods

Participants aged 40-59 were recruited from the National Health and Nutrition Examination Survey (NHANES) 2011-2018. Muscle mass was quan
