Abstract Objective. This study describes the magnitude and characteristics of nutritional rickets and associated risk factors among children in Qatar. Subjects. A consecutive sample of 730 healthy subjects who visited the primay health care clinics were approached and 540 (73.9\%) subjects gave consent. Mehods. Nutritional rickets diagnosis was based on clinical radiologic and biochemical parameters and normalization of alkaline phosphatase level after 6 weeks course of daily vitamin D therapy. Results. The study revealed that 23.9\% of the studied children had nutritional rickets. The mean ± SD age of those with rickets (3.76 years ± 1.51) was slightly higher than those without rickets (3.57 years ± 1.45). Family history of vitamin D deficiency (44.2\%; P = .001) and diabetes mellitus (53.5\%; P = .002) were significantly higher in rachitic children than in nonrachitic children. The children with rickets spent a significantly shorter average duration (26.86 minutes ± 19.94) under the sun than those without rickets (30.59 minutes ± 15.72; P < .001). A significantly larger proportion of rachitic children was afflicted with vitamin D deficiency (75.2\% versus 62.2\%; P < .001), secondary hypothyroidism (100\% versus 7.5\%; P = .009) and muscular weakness (56.6\% versus 26.3\%; P < .001). Conclusion. The most important risk factors were low vitamin D and calcium intakes, lack of exposure to sunlight, prolonged breast feeding without supplementation of vitamin D.
