The Effect of Vitamin D Deficiency and Exposure to Endocrine-Disrupting Chemicals on Sleep Duration in Adults
Written by Harold Oster, MD. Results suggest that exposure to endocrine-disrupting chemicals has a variable association with sleep duration, and vitamin D deficiency may affect this interaction. Insufficient sleep, which is reported by more than 25% of Americans, is...
The Association of Metabolic and Dietary Variables with Periodontitis in Adults with and without Diabetes
Written by Harold Oster, MD. Results suggest that diabetics with periodontitis are more likely than non-diabetics to have low vitamin D levels and a diet low in fruits and vegetables. Periodontitis is a chronic condition of the support structures of the teeth. Chronic...
Vitamin D Deficiency Associated with Increased Stroke Severity in Acute Ischemic Stroke Patients
Written by Taylor Woosley, Staff Writer. Multivariable analysis findings show that lower serum Vitamin D levels were associated with an increased risk of stroke severity (p < 0.001) and poor functional outcomes. The incidence of cerebrovascular diseases is on the...
Vitamin D Deficiency Associated with Increased Risk of Preterm Birth in Pregnant Black Women
Written by Taylor Woosley, Staff Writer. Women with vitamin D deficiency were 2.80 times as likely to have a PTB compared to women with sufficient vitamin D levels (p ≤ 0.01). Preterm birth (PTB; birth <37 weeks gestation) is the second leading cause of infant...
Factors Associated with Inadequate Vitamin D Levels in Older Chinese Adults
Written by Harold Oster, MD. Results suggest that vitamin D insufficiency is more likely in women, ethnic minorities, residents of temperate latitudes and urban areas, and those with obesity or anemia. The prevalence of vitamin D insufficiency is increasing...
