BACKGROUND AND AIMS:
Several studies have reported that regular consumption of breakfast is associated with health benefits. However, only a few studies have examined the association between frequency of breakfast consumption and muscular function. Therefore, this study aims to investigate the association between frequency of breakfast consumption and muscle strength among apparently healthy Japanese adults.
METHODS AND RESULTS:
A cross-sectional study design was used. Between 2008 and 2011 in Sendai, Japan, 1415 Japanese adult employees (1069 men and 346 women) aged between 19 and 83 years participated in the study. Grip strength, as measured by a handheld digital dynamometer, was used as an indicator of muscle strength. Frequency of breakfast consumption during the previous month was assessed using a brief self-administered dietary history questionnaire, and the results were divided into three categories for analysis: low (≤2 days week-1), middle (3-5 days week-1) and high (≥6 days week-1). Multivariate analysis was performed using analysis of covariance, with covariates mainly including socio-demographic, lifestyle-related and health-related factors. After adjusting for several potential confounders, grip strength was shown to be positively associated with breakfast consumption frequency (geometric means, 95% confidence interval (CI): low frequency, 36.2 (35.7-36.8) kg; middle frequency, 36.7 (36.0-37.5) kg; high frequency, 37.0 (36.6-37.5) kg; P for trend = 0.03). Grip strength per kilogramme body weight (kg kg-1) was also positively associated with frequency of breakfast consumption (P for trend = 0.01).
CONCLUSIONS:
This cross-sectional study reveals a positive association between breakfast consumption frequency and muscle strength in apparently healthy adults.
