Assessment of serum vitamin D level in third trimester of multiparous women of Sargodha region with relation to sun exposure and age group.
Objectives: To assess serum vitamin D level in third trimester multiparous pregnant females and correlate them with different parameters (sun exposure and age). Study Design: Cross Sectional study. Setting: Department of Pathology, SMC, UOS, Sargodha. Period: April 17th to September 17th, 2017. Material & Methods: A total of fifty multiparous pregnant women in 3rd trimester were included in this study. On the basis of their 25 hydroxy vitamin D (25OHD) levels, pregnant women were categorized into 2 groups: normal (>30ng/ml) and deficient (<20ng/ml). Vitamin D level was measured by CLIA (chemilumuniscence immunoassay analyzer). Data related to sun exposure and age groups was recorded on self structured questionnaire. Results: We found that 47 multiparous women (94%) were vitamin D deficient and 3 (6%) had normal vitamin D levels. Based on associated findings, results showed significance between vitamin D and day time of sun exposure (p =0.02), vitamin D and duration of sun exposure (p =0.01). A significant difference between vitamin D and different age groups (p =0.03) was also observed in multiparous pregnant females. Conclusion: My study suggested that multiparous pregnant women are more susceptible to vitamin D deficiency. A significant association exists between vitamin D and day time of sun exposure, duration of sun exposure and age groups among multiparous pregnant women.
