Özet

Objective: To determine whether a person’s circadian rhythm produces peak alertness time and how this affects nutritional status and sleep quality (SQ). Method: This study involved 65 shift (SW) and 85 fixed workers (FW) (18–55 years). Chronotypes were determined using Morning-Evening Questionnaire (MEQ). SQ was measured using Pittsburgh SQ Index (PSQI). eating behaviors were evaluated using Three Factor Eating Questionnaire (TFEQ-R21) and Food Frequency Questionnaire (FFQ), and mental health was assessed using the Depression, Anxiety, and Stress Scale (DASS-21). Results: Most women in FW had a morning chronotype (47.5%, pWomen = 0.011), whereas 70.8% of SW had an intermediate chronotype (pTotal = 0.004). SW had poorer SQ compared to FW (pTotal = 0.013). Regression analysis showed that chronotype, DASS score, and egg consumption frequency were significant predictors of SQ.(R2 = 0.217, p < 0.001). Conclusions: Work patterns significantly impact circadian rhythms, nutritional status, and SQ. SW are more likely to have intermediate chronotypes and poorer SQ.
