Effect of Vitamin D3 Supplementation on Levator Ani Muscle Strength in Primipara Pregnancy with Postpartum Vitamin D3 Deficiency

Abstract

Objective: To determine the benefits of post-partum vitamin D supplementation on striated muscle strength. Methods: This is a pre-post quasi-experimental study on postpartum vitamin D3 supplement provision in primiparous women with vitamin D3 deficiency. The effect of vitamin D3 supplement was assessed through the measurement of pelvic floor muscle strength before and after 3 months of vitamin D3 supplementation. Thirty-three primiparous postpartum women with spontaneous vaginal delivery who met inclusion criteria participated in this study. Serum vitamin D3 level, basal tone, and maximum levator ani contraction were measured by perimetry prior to and after vitamin D3 supplementation. This study was conducted in the Obstetric Clinic and Clinical Serology Laboratory of Clinical Pathology Department, Dr. Hasan Sadikin General Hospital/Faculty of Medicine, Universitas Padjadjaran from March 1 to May 31, 2018. Results: Data analysis using the Wilcoxon test showed an increase in serum vitamin D3 level and a basal tone strength after vitamin D3 supplementation with a P-value of <0.001. However, the maximum strength of levator ani muscle contraction did not increase (P-value <0.829). Conclusions: Vitamin D3 supplementation increases basal tone strength.
