Objective: To investigate the frequency of breakfast consumption among workers who often have short daily rest periods (DRPs).
Methods: Cross-sectional data were collected from the “WELWEL” study, which surveyed 20,000 Japanese workers in February 2022. The relationships between the number of days per month with DRPs less than 11 hours and the frequency of breakfast consumption were examined using the Kruskal-Wallis test, Mann-Whitney U test, and multinomial logistic regression analysis. The analyses were conducted separately by sex.
Results: Among the participants, 9,221 (53.9%) were male. Among these, 5,790 (62.8%) had breakfast almost every day, and 7,113 (83.6%) had at least one day with DRP<11 hours. Among the female participants, 5,534 (70.0%) had breakfast almost every day, and 7,079 (89.6%) had at least one day with DRP<11 hours. Multinomial regression revealed that the odds ratio of rarely eating breakfast was higher only in males with each additional day with DRPs<11 hours, regardless of sociodemographic characteristics and lifestyle habits (adjusted odds ratio [95% CI] among males: 1.02 [1.01, 1.03], females: 1.00 [0.98, 1.02]).
Conclusion: Males who had shorter DRPs displayed a higher likelihood of skipping breakfast. Therefore, measures should be taken to secure sufficient DRPs for workers.
