Prevalence of osteoporosis and its associated factors in older adult’s users of the Primary Health Care

Abstract

This study examine the prevalence and factors associated to osteoporosis among older adults users of the primary health care. This cross-sectional study was carried out with 654 older adults (56% women) from primary health care in Maringá, Paraná, Brazil. The instruments used were the sociodemographic questionnaire and the International Physical Activity Questionnaire (IPAQ), short version. Data analysis was conducted through Chi-square test and Binary Logistic Regression (p < 0.05). The results showed a prevalence of 15.6% of older adults who reported the presence of osteoporosis. There was a higher prevalence of women with osteoporosis (p = 0.001), and on the other hand, there was a greater proportion of married elderly individuals (p = 0.003), and elderly with income above three minimum wages (p = 0.020) with absence of osteoporosis. The results showed that women (OR = 4.45; 95%CI: 2.47-8.01) and the older adults who take more than two medications (OR = 1.67; 95%CI: 1.15-2.42) were more likely to present osteoporosis. Older adults who presented a history of falls are 47.0% more likely to present osteoporosis. It was concluded that sex, the amount of medications and the history of falls are associated with the prevalence of osteoporosis in the older adults.
