Syndrome d’apnée hypopnée obstructif du sommeil en Afrique Sub-saharienne : une revue de la littérature

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is common, under diagnosed and severe. It increases cardiovascular morbidity and mortality, reduces life expectancy and alters the quality of life.The objective of this work was to review the scientific literature on OSAHS in Sub-Saharan Africa from 2009 to September 2019.A search on PubMed, Science Direct, African Index Medicus, African Journals on line and Google scholar found a total of 43 references relevant to the theme.OSAHS publications are scarce in sub-Saharan Africa with no data for 36 countries. Practitioners’ level of knowledge about the disease was low. Polygraphy and / or polysomnography were not available in the majority of Sub-Saharan African countries. The prevalences obtained remained higher than those found in Europe and USA. OSAHS predominated in men, with a peak around 55 years old. The most consistent risk factor was obesity. The association OSAHS chronic pathology remained frequent. The excessive cost of continuous positive pressure, surgery and the lack of health insurance in these countries limited access to treatment.We need to improve the knowledge, in sub-Saharan Africa, of practitioners in the field of sleep medicine, to make polysomnography available in public health structures, to create sleep units in teaching hospitals to strengthen practical training and finally to make accessible treatment.
