• Registration Number: NCT02921204
• Lead Sponsor: Princess Nourah Bint Abdulrahman University

Brief Summary

Vitamin D deficiency is most diagnosed among women living in the Kingdom of Saudi Arabia. Many factors have been attributed to the incidence of vitamin D deficiency. Saudi women are thought to be at greater risk for vitamin D deficiency because of their darker skin type and the likelihood of reduced ultraviolet exposure . The present study entitled, "Dietary Intake and Vitamin D Level in adult Women," was formulated as there is paucity of data on the etiologic importance of dietary intake in Vitamin D level on blood on women. The major objective of the proposed study is to assess the effect of dietary intake of nutrients and level of vitamin D in women .

Detailed Description

For this study, the investigators enrolled 168 women 35-55 years old to evaluate Vitamin D status and to determined whether status was correlated with Vitamin D deficiency.

All women completed a self-administered questionnaire about personal socio-demographic characteristics; They all had anthropometric measurements of body mass index and waist circumference. A 24-hour dietary recall was administered to all women.
