Association between skeletal muscle mass index and presence or absence of breakfast intake in community-dwelling healthy adults

Abstract

【Purpose】To examine the association between skeletal muscle mass index (SMI) and breakfast intake.
【Methods】This is a cross-sectional study. The study included 51 participants participating in the physical fitness test in Y city. The cohort included 40 participants with breakfast intake (mean age, 59 ± 11 years; females, 70%) and 11 participants without breakfast intake (mean age, 59 ± 11 years; females, 91%). Regression analysis were used to examine the association between SMI and breakfast intake, and covariates were introduced to adjust for confounding in additional modeling.
【Results】SMI was significantly associated with breakfast intake [reference, breakfast intake group; unstandardized coefficient B = -1.01 (-1.84 ～ -0.16); p = 0.020]. Moreover, significant association [unstandardized coefficient B = -0.75 (-1.49 ～ -0.00); p = 0.049] was even observed in the model including covariates.
【Conclusion】Our analyses suggest that breakfast intake is necessary to maintain SMI in community-dwelling healthy adults.
