Among the 100 suspected rickets child, mean age was 29.36±13.09 SD (months). There  were 64% (n=64) male and rest of them (36%, n=36) were female. Of all, the frequency of rickets was 90%, wherein the frequency of nutritional rickets was 87.78% (n=79). Male sex is associated with higher proportion of NR than female child. Limb deformity is the most common features in group of child and bowing leg, swelling and widening of wrist, rickety rosary and knock knee were present in 51.9%, 27.8%, 26.6% and 25.3% children respectively.
