Caffeine intake is nonlinearly associated with muscle mass in young and middle-aged US adults.

ABSTRACT:

Background

Recent studies have indicated that coffee consumption is inversely correlated with sarcopenia in the elderly population. Data regarding the association between caffeine intake and muscle mass in young adults are scarce.

Objective

We aimed to investigate how dietary caffeine correlates with muscle mass and sarcopenia in the young and middle-aged people.

Methods

We performed a cross-sectional study utilizing data from NHANES. Muscle mass was evaluated using DXA and caffeine intake was derived from 24-h dietary recalls. Multivariable regression analysis was adopted to explore association between caffeine and sarcopenia. Restricted cubic spline analysis was conducted to investigate dose-response effect of dietary caffeine on muscle mass. Mediation effect of hig
