Sleep quality and nutrition habits among shift and fixed working staff

OpenAlex İngilizce

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.
