Association Between Three-Months Vitamin D Supplementation and Depressive Symptomatology incidence among Saudi Arabian Adults
Published 2022“…At baseline, when adjusting for age and gender only, we observed that lower vitamin D serum levels were associated with higher depression prevalence. When vitamin D was considered as continuous variable, each unit increase in vitamin D levels was associated with a lower depression prevalence (OR=0.87; 95% CI:0.79-0.95, p=0.005) and when compared to those insufficient, those deficient were 4 times more likely to suffer from depression (OR=4.47, 95% CI:1.39-14.38,p=0.012) Nevertheless, these significant results were lost with further adjustment for BMI, MeDi adherence and physical activity: continuous vitamin D: OR=0.90; 95% CI: 0.81-1.01, p=0.08, deficient versus insufficient:OR=2.18; 95% CI: 0.56-8.47,p=0.259). …”
