Purpose: This study aims to evaluate the relationship between dietary patterns and shift work, sleep quality and burnout among emergency health-care workers. Design/methodology/approach: The nutritional status, sleep quality and burnout status of health-care workers (n = 91) in Turkey were investigated. Findings: Among the burnout subgroups, only emotional exhaustion was associated with high adherence to the Meditarrenean diet. (r = 0.37, p < 0.01). Carbohydrates consumed during the shift day were associated with lower sleep quality (r = 0.24, p = 0.02). The intake of protein (r = −0.29, p < 0.01), fat (r = −0.27, p < 0.00), cholesterol (r = −0.31, p < 0.01), phosphorus (r = −0.22, p = 0.03) and iron (r = −0.21, p = 0.04) in shift day was negatively associated with Pittsburgh Sleep Quality Index (PSQI) scores (lower PSQI scores indicates good sleep quality). Consumption of vitamin C and potassium on the rest day was significantly associated with better sleep quality (respectively, r = −0.21, p = 0.04 and r=−0.23, p = 0.03). Personal accomplishment was positively correlated with carbohydrate consumption during the shift day and negatively correlated with protein, cholesterol and vitamin B6 intake (respectively, r = 0.22, p = 0.03; r = −0.21, p = 0.03; r=−0.28, p < 0.00, r = −0.28, p < 0.00). Emotional exhaustion was negatively correlated with protein consumption on the shift day (r = −0.21, p = 0.04) and positively correlated with fat consumption on the rest day (r = 0.22, p = 0.02). Originality/value: The findings confirm the possible role of dietary patterns in health-care workers against burnout and sleep quality attributable to a possible association with nutrients intake on shift or rest day.
