Perfil epidemiológico de pacientes com osteoporose atendidas em ambulatório especializado.

Abstract

Osteoporosis is an osteometabolic disease determined by low bone mineral density (≤ -2.5 standard deviation) and deterioration of the bone tissue microarchitecture. Such morbidity, commonly associated with sarcopenia, comes from a multifactorial etiology and considerably increases the risk of bone fractures due to weakness, leading to a negative impact on people’s lives.The goal was to typify female patients with osteoporosis served in the outpatient facilities of Endocrinology and Rheumatology of Hospital Universitário Alcides Carneiro for the period from August/2019 to October/2019 in terms of epidemiological profile, bone fracture risks, bone loss rate, and the predominance skeletal site, as well as, to project osteoporosis prevalence within this population. Transversal descriptive observational study involving female patients older than 18 years old with osteoporosis densitometric diagnosis. A structured questionnaire was conducted with the measurement of both weight and height to the computation of the Body Mass Index (BMI), in addition to the calf circumference measurement. The valid sample includes 42 patients, with an average age of 66.88 years old (± 7.57). The osteoporosis prevalence was 8.69%, considering the study population (483 women). The part of the population who practice physical exercises at least 2x a week has shown 15% bone fracture incidence, whereas the sedentary part has shown 54%. Furthermore, there was an inverse association between the physical activity and the bone mass loss. Moreover, the 2.5x increase in the bone fracture risk occurred in the face of a 1SD reduction in the mineral bone density. Smaller measures of calf circumference were related to significant bone loss, with an

average -4.5 to -5.4 SD. It was verified an absolute correlation (r=1) within the cut- off values from 31 cm to 33 cm to sarcopenia tracking. It is extremely important the

tracking and monitoring of osteoporosis on a more effective way on the population assisted in the HUAC, so more vulnerable groups could be identified sooner, and, as a result, prevent the main complication associated to osteoporosis, which is the fragility fracture.
