Interactions between pregnant women's nutrition habits, psychological well-beings, sleep quality and biochemical parameters.

Objective: Hormonal changes during pregnancy may cause various changes in biological, physiologic and psychosocial areas. The main objective of this study was to analyze the relationship between dietary habits, psychological well-being, sleep quality and biochemical parameters of pregnant women.

Methods: The study was conducted on a total of 93 patients who applied to Ankara Koru Sincan Hospital Gynecology and Obstetrics Outpatient Clinic for routine pregnancy control between November-December 2023, were between the ages of 18-45, had a live singleton fetus, had no diagnosed psychiatric disease or chronic disease, and agreed to participate in the study. Anthropometric measurements and biochemical findings of the individuals were recorded with a questionnaire including the psychological well-being scale (PWBS) and Pittsburgh sleep quality index (PSQI).

Results: According to the study, PSQI scores during the second and third trimesters are significantly higher than the first trimester. It was observed that while individuals have bad sleep quality during the second and third trimesters, they have good sleep quality during the first trimester (χ² = 14.736; P < 0.001). In the biochemical results, the thyroid-stimulating hormone (TSH) value in the second trimester was higher (P > 0.05). Weight gain during pregnancy, age and trimester have a negative effect on sleep quality.

Conclusion: When the effects of lifestyles and eating habits of pregnant women on the process are considered, there is a relationship between smoking/alcohol consumption, less physical activity, poor eating habits, sleep quality and depressive symptoms. Factors such as age, educational background, trimester period and other basic sociodemographic variables are also involved.
