In developing countries, deficiency rickets are the main cause of rickets. In Senegal, there are no national guidelines for vitamin D supplementation. The objective of this study was to determine the epidemiological profile, diagnosis and prognosis of rickets in children. This was a retrospective study carried out over 7 years and included all children under 15 years of age who were being followed for rickets. During this period, 13 cases of rickets were collected, representing 3.1% of endocrine pathologies (dysthyroidism, puberty disorders, growth disorders, sexual development abnormalities, diabetes) and 0.4% of hospitalizations. The M/F sex ratio was 0.8. The age range [6 months-2 years] was the most representative 46.1%. The mean age at diagnosis was 2 years [6 months-5 years]. More than 4 out of 5 children (84.6%) were breastfed in their first 6 months of life. Skeletal abnormalities and gait disorders were the main clinical signs. Blood calcium was low in 76.9 % and blood phosphorus in 92.3 %. Blood vitamin D3 was low in 100% of cases with a mean of 13.2 ng/mL. The rickets were either deficiency rickets (46.1%), vitamin resistant type 2 rickets (38.5 %) or rickets secondary to chronic renal disease (15.4%). Deficiency rickets remains the main cause of rickets in our country, especially in infants. There is a need to implement national guidelines for routine vitamin D supplementation and to raise awareness of good dietary practices on a regular basis.
