(P22-056-24) Evaluation of Serum 25-Hydroxy Vitamin D Levels and Dietary Patterns in Pregnancy-induced Hypertension

Objectives: Pregnancy-induced hypertension (PIH) poses significant risks to maternal and fetal health. The etiology of PIH is multifactorial and warrants further investigation. Assessing serum 25-hydroxy vitamin D (25(OH)D) levels and dietary patterns in pregnant women with PIH is crucial for identifying potential risk factors and developing targeted interventions.

Methods: The present study was an observational case-control research endeavor. A cohort of 160 pregnant women were recruited (80 individuals in each group). Participants were drawn from pregnant women referring to specialized obstetrics and gynecology clinics and healthcare centers in Ahvaz, Iran. Data on anthropometric indices, physical activity, blood pressure history, serum 25(OH)D levels, sunlight exposure, and major dietary patterns were collected.

Results: There were no significant differences in age, BMI, physical activity, and blood pressure history between the two groups. However, serum 25(OH)D concentrations and exposure to sunlight were significantly lower in the case group. No significant correlation was observed between 25(OH)D levels and dietary patterns in either group. Notably, a significant correlation was identified between BMI and Traditional and Western dietary patterns.

Conclusions: These findings underscore the potential impact of 25(OH)D levels and sunlight exposure on PIH, as well as the association between BMI and specific dietary patterns.
