	Frequency of balanced meal consumption
	Daily	4‐5 days/week	2‐3 days/week	≤1 day/week	P for trend*
Participants with/without depressive symptoms	80/742	57/427	121/596	106/328
Model 1 †	1.00 (ref)	1.19 (0.83‐1.71)	1.83 (1.34‐2.50)	2.78 (1.99‐3.88)	< 0.001
Model 2 ‡	1.00 (ref)	1.09 (0.75‐1.58)	1.62 (1.17‐2.24)	2.21 (1.54‐3.17)	< 0.001

^*Based on multiple logistic regression analyses, assigning ordinal numbers of 1‐4 to the categories of frequency of balanced meal consumption.

^† Adjusted for age (years, continuous), sex, work site (Tokyo or Chiba), and occupation (doctor, nurse, allied healthcare professional, administration, or other).

^‡ Adjusted for age (years, continuous), sex, work site (Tokyo or Chiba), occupation (doctor, nurse, allied healthcare professional, administration, or other), leisure‐time physical activity (none,<1, 1 to <2, or ≥2 hours/week), smoking status (never‐smoker, quitter, or current smoker [cigarette or heat‐not burn cigarette]), alcohol consumption (nondrinker or quitter, weekly drinker consuming <1, 1 to <2, or ≥2 go/day; one go contains approximately 23 g of ethanol), sleep duration (<6, 6‐6.9, or ≥7 hours/day), body mass index (<18.5, 18.5–<23, 23–<25, 25–<30, or ≥30 kg/m²), comorbidity of chronic disorders (yes or no), living arrangement (living alone or living with others), and frequency of eating with others (<1 or ≥1 day/week), working hours (≤8, 9‐10, or ≥11 hours/day) and degree of possible exposure to SARS‐CoV‐2 (low, moderate, or high).
