Background In Algeria, no epidemiological data on postmenopausal osteoporosis is available which justified this study of prevalence of postmenopausal osteoporosis in our country
Objectives To determine the prevalence of densitometric osteoporosis in postmenopausal women aged 45 and over, living in Douera (Algiers). Look factors to the occurrence of osteoporosis and determine the frequency of fragility fractures
Methods A prospective epidemiological cross-sectional study in which women were selected on the basis of the method of cluster sampling of the first degree in locality of Douera (Algiers)
Results 546 postmenopausal women 45 years and older were included in the study with an average age of 62±9.42 years (range: 45-89 years), personal and family history of documented fractures were found respectively in 21% and 11% of the population
Osteoporosis was found in 41.7% (CI: 35% - 48%) of postmenopausal women.
The adjusted prevalence of osteoporosis in the Algerian population of women aged 45 years and older was 35.8%.
Among the risk factors sought those related to the occurrence of osteoporosis in varied plain analysis and after adjustment, respectively, I'IMC <26 kg/m2 (OR: 4.32 (1.54 to 12.10) p<0.005), weight <60 kg (OR: 3.28 (1.18 to 9.14) p<0.023), the duration of menopause >15 years (OR: 3.46 (1.41 to 8 50) p<0.007), personal history of fractures (OR: 3.77 (1.58 to 8.9), p<0.003) and the low level of education (OR: 2.34 (1.18 - 4.62) p<0.014).
Conclusions postmenopausal osteoporosis seems common in our study, a number of potential risk factors was determined and who deserves to be validated by a larger study on a representative sample of the Algerian population
