Nutrition status and diet quality in healthcare professionals with different chronotypes: a comparative study

ABSTRACT

This study aimed to examine the nutritional status of healthcare professionals with different chronotypes and to determine their diet quality. Of the health care professionals (n = 204), 10.3% were morning chronotype (n = 21), 14.2% were evening chronotype (n = 29) and 75.5% were intermediate chronotype profiles (n = 154). Daily carbohydrate intake was significantly higher in the evening chronotype participants than was that in the morning and intermediate chronotype participants (p < 0.05). Daily intake of total fat, saturated fat, monounsaturated fatty acid (MUFA), and sodium in all the participants was above the population-specific recommended values, and saturated fat intake was highest in the evening chronotype participants. Nutritional status (except carbohydrate and potassium) and diet quality of healthcare professionals participating in the present study did not differ according to their chronotypes. Their diet quality was not good and their energy and nutrient intakes were below the requirements.
