Clinical Trial 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 .

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.

The proximate analysis of 25 types of food was conducted according to the American Association of Organic Chemists (AOAC) methods. The following parameters were measured: serum calcium. Vitamin D, levels of parathyroid hormone.
