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
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?<?0.0001) and inversely correlated with PTH (r?=?-0.3, p?=?0.01). Levels below 20 ng/ml were considered as vitamin D deficiency. PTH was normal in 87% of vitamin D-deficient subjects from Yeshiva-A and Yeshiva-C (mean age 20), compared to 52% of Yeshiva-B students (mean age 33). Bone mineral density studied in a random subset (n?=?14) of vitamin D-deficient subjects showed Z-scores of -1.5?±?1.0, -1.8?±?0.8, -2.1?±?0.4 in femoral neck, spine and radius.

CONCLUSIONS: Severe vitamin-D deficiency is extremely prevalent in ultra-Orthodox males. Despite rare secondary hyperparathyroidism, they represent an important previously unrecognized high-risk group for metabolic bone disease. DOI: 10.1007/s00198-010-1492-y * PMID: 21110005
