RESUMO
PURPOSE OF THE STUDY: Osteoporotic fractures are an important public health problem due to significant morbidity and mortality and the socioeconomic burden. In Tunisia, the impact of such fractures is often underestimated due to lack of epidemiological data. We evaluated the prevalence of these fractures in a sample population at risk in order to better ascertain the amplitude of this problem in our country. MATERIAL AND METHODS: This prospective study involved 2,000 menopaused women aged 50 years or more. The sample was randomly selected among the population of Manouba, an urban administrative district of the capital of Tunisia. One thousand three hundred eleven women agreed to participate in this survey. Women with a risk of secondary osteoporosis were excluded. We retained for study fractures related to primary osteoporosis. History taking recorded anthropometric data and medical history, particularly gyn-ob history. All fractures occurring after minor trauma, in women aged 50 years or more, and involving the femoral neck, the wrist, or the proximal humerus were noted. Lateral x-rays of the thoracolumbar spine were studied to search for unrecognized vertebral fractures. RESULTS: The study population included 1,311 women, mean age 64.07 +/- 9.31 years, menopaused at mean 48.29 +/- 3.84 years. Among these women, 212 (16.2%) had presented a fracture at one of the localizations retained for study. Vertebral wedge fractures accounted for 59.83% of all fractures, wrist fractures 31.96%, proximal femoral fractures 4.51% and proximal humeral fractures 3.69%. DISCUSSION: Osteoporotic fractures are not uncommon in women in Tunisia. Increasing life expectancy in our country suggests this public health problem will grow in the years to come, pointing out the importance of better management of osteoporosis to prevent fractures.
