Ultra-orthodox Jewish lifestyle, which encourages modest dress and indoor scholarly activity, represents a risk factor for vitamin-D deficiency. Our study in healthy young males from higher education religious institutions located in the same geographical area showed frequent and severe vitamin D deficiency, strongly correlated with the degree of sun exposure. However, PTH level was usually normal.

INTRODUCTION: Ultra-orthodox Jewish lifestyle encourages modest dress and indoor scholarly activity. As such, it represents a risk factor for vitamin-D deficiency, a worldwide problem previously underestimated in sunny countries. Our aim was to characterize the vitamin-D status of religious Jewish males according to sun exposure and outdoor activity, and study the correlation between serum 25-hydroxyvitamin D (25(OH) D) and PTH level.

METHODS: Seventy-four young adult males were recruited from three Jewish higher education institutions (Yeshiva) in Jerusalem.

  • Yeshiva-A ultra-Orthodox students (aged 20.1?±?0.6) wear traditional clothing, live in dormitories and stay mostly indoor.

  • Yeshiva-B ultra-Orthodox students (aged 33.0?±?4.2) dress similarly but have regular outdoor activities.

  • Yeshiva-C religious students (aged 19?±?2.0) participate in a mixed army/Yeshiva program.

Weekly outdoor activity time and degree of sun exposure were estimated by questionnaire.

RESULTS: 25(OH)D was

8.9?±?3.6,

10.2?±?5.7 and

21.7?±?10.4 ng/ml (mean?±?SD)

in Yeshiva A, B and C.

25(OH)D was correlated with degree of sun exposure (r?=?0.54, p?
