Abstract
• Rachitic children had less height for age SDS because of their deformities which made them shorter with those deficient in dietary calcium intake the shortest.
• Rachitic children who were younger in age and breast fed were deficient in vitamin D only as they obtained their smaller calcium requirements through breast feeding.
• Rachitic children attending the outpatient clinic of the Pediatrics Hospital Ain Shams University were of low socioeconomic class.
• Calcium intake of the rachitic children as a whole was lower than the recommended daily intake and lower than that of the controls with the children of the older age group, who had more RDI, more deficient in calcium intake either alone or combined with deficient sun exposure.
• Calcium deficiency is an important operating factor in the pathogenesis and development of rickets in older rachitic children.
• All 3 groups of patients had a median time to healing of 3 months.
• One injection of vitamin D 600.000 IU was sufficient for healing of rickets in those who had deficient sun exposure.
