Résumé
To assess the knowledge of doctors working in Karachi about Vitamin D deficiency. This descriptive cross-sectional study was carried out at public and private hospitals and clinics in Karachi from January 2010 to March 2010. Four hundred doctors registered with the Pakistan Medical and Dental Council [PMDC] working in Karachi were included in the study. A well structured, pre-tested questionnaire was designed to gather data. Each interview was completed by an investigator. Questions included the sources and metabolism of vitamin D, deficiency of vitamin D, its presentation in clinics and its management. Questionnaires were completed by 400 doctors. The results indicate that doctors are aware of the sources and metabolism of vitamin D but lack information about the duration and factors regarding sunlight exposure. The physicians generally have good information about the signs and symptoms of vitamin D deficiency and the factors causing it, but do not have sound information about deficiency management. The results support the fact that doctors need more knowledge and training about vitamin D deficiency
