    Persistent hypovitaminosis D and loss of hip bone mineral density over time as additional risk factors for recurrent falls in a population-based prospective cohort of elderly persons living in the community. The Sao Paulo Ageing & Health (SPAH) Study
    (2015) MACHADO, K. L. L. L.; DOMICIANO, D. S.; MACHADO, L. G.; LOPES, J. B.; FIGUEIREDO, C. P.; TAKAYAMA, L.; OLIVEIRA, R. M.; MENEZES, P. R.; PEREIRA, R. M. R.
    A Summary We performed concomitant evaluation of clinical, laboratory, and bone mineral density (BMD) parameters as potential risk factors for falls in a population-based prospective cohort of older adults, since previous studies have focused mostly in clinical risk factors. Loss of hip BMD and persistent hypovitaminosis D were associated with recurrent falls in community-dwelling elderly. Introduction Few studies have performed a concomitant evaluation of clinical data, laboratory bone parameters, and bone mineral density (BMD) to determine more accurately the contribution of each of these variables to risk of falls in elderly persons. We investigated the association between bone parameters and recurrent falls in a population-based prospective cohort of community-dwelling older adults. Methods A total of 705 elderly individuals (448 women, 257 men) were evaluated with clinical data, BMD, and laboratory bone tests at baseline and after a mean follow-up of 4.3 +/- 0.8 years. Individuals with recurrent falls (a parts per thousand yen2 falls in the previous year from the date of the second evaluation) were considered chronic fallers. Logistic regression models were used to identify independent risk factors for recurrent falls. Results The frequency of chronic fallers was 16.5 %. In multivariate analyses, risk factors for recurrent falls were visual impairment (odds ratio (OR) = 2.49, 95 % confidence interval (CI) 1.30-4.74, p = 0.006), use of psychotropic drugs (OR = 2.47, 95 % CI 1.37-4.49, p = 0.003), clinical fracture (OR = 2.78, 95 % CI 1.48-5.20, p = 0.001), persistently low 25-hydroxyvitamin D (25OHD) (< 20 ng/mL) (OR = 1.71, 95 % CI 1.10-2.64, p = 0.016), and loss of total hip BMD during the study (OR = 1.21, 95 % CI 1.17-1.25, p = 0.035 for each 4 % decrease). Conclusions In addition to traditional clinical risk factors for falls, loss of hip BMD and hypovitaminosis D were associated with recurrent falls in community-dwelling elderly persons. Thus, recognizing these factors is essential to preventing falls and improving the outcomes of this population.

    Incidence and risk factors for osteoporotic vertebral fracture in low-income community-dwelling elderly: a population-based prospective cohort study in Brazil. The Sao Paulo Ageing & Health (SPAH) Study
    (2014) DOMICIANO, D. S.; MACHADO, L. G.; LOPES, J. B.; FIGUEIREDO, C. P.; CAPARBO, V. F.; TAKAYAMA, L.; OLIVEIRA, R. M.; MENEZES, P. R.; PEREIRA, R. M. R.
    We ascertained the incidence and predictors of radiographic vertebral fracture in a Brazilian elderly cohort, since no data in this field have been reported in low-income countries. This is the first population-based study to demonstrate the high frequency of vertebral fracture in elderly Latin Americans. Age, prior fracture, BMD, and bone turnover were predictors of fracture. Vertebral fractures are associated with increased future fracture risk and mortality. No data on incidence of osteoporotic vertebral fracture have been reported in low-income countries where the population's aging has been faster. Thus, we sought to describe the incidence and risk factors for radiographic vertebral fracture in a longitudinal prospective Brazilian population-based elderly cohort. 707 older adults (449 women and 258 men) were evaluated with spinal radiographs obtained at baseline and after a mean follow-up of 4.3 +/- 0.8 years. New vertebral fracture was defined as distinct alteration in the morphology of vertebrae resulting in higher grade of deformity on the second radiograph when compared to the baseline radiograph. Clinical questionnaire, bone mineral density (BMD), and laboratory tests were performed at baseline. Multivariate Poisson regression models were used to identify independent predictors of fracture. The age-standardized incidence of vertebral fracture was 40.3/1,000 person-years in women and 30.6/1,000 in men. In women, three models of risk factors for fracture were fitted: (1) age (relative risks (RR) 2.46, 95 % confidence interval (CI) 1.66-3.65), previous osteoporotic fracture (RR 1.65, 95 % CI 1.00-2.71), and lumbar spine BMD (RR 1.21, 95 % CI 1.03-1.41); (2) age (RR 2.25, 95 % CI 1.52-3.34) and femoral neck BMD (RR 1.42, 95 % CI 1.11-1.81); (3) age (RR 2.11, 95 % CI 1.41-3.15) and total hip BMD (RR 1.56, 95 % CI 1.21-2.0). In men, the highest quartile of cross-linked C-telopeptide (CTx) (RR 1.96, 95 % CI 0.98-3.91) and prior fracture (RR 2.10, 95 % CI 1.00-4.39) were predictors of new vertebral fracture. This is the first population-based study to ascertain the incidence of vertebral fracture in elderly Latin Americans, confirming the high frequency of the disorder. Age, prior fracture, BMD, and bone turnover were predictors of the short-term incidence of vertebral fracture.

    Visceral fat measured by DXA is associated with increased risk of non-spine fractures in nonobese elderly women: a population-based prospective cohort analysis from the So Paulo Ageing & Health (SPAH) Study
    (2016) MACHADO, L. G.; DOMICIANO, D. S.; FIGUEIREDO, C. P.; CAPARBO, V. F.; TAKAYAMA, L.; OLIVEIRA, R. M.; LOPES, J. B.; MENEZES, P. R.; PEREIRA, R. M. R.
    The present study investigates the relationship between visceral fat measured by dual-energy X-ray absorptiometry (DXA) and the incidence of non-spine fractures in community-dwelling elderly women. We demonstrated a potential negative effect of visceral fat on bone health in nonobese women. The protective effect of obesity on bone health has been questioned because visceral fat has been demonstrated to have a deleterious effect on bone. The aim of this study was to investigate the association of visceral fat measured by DXA with the incidence of non-spine fractures in community-dwelling elderly women. This longitudinal prospective population-based cohort study evaluated 433 community-dwelling women aged 65 years or older. A specific clinical questionnaire, including personal history of a fragility fracture in non-spine osteoporotic sites, was administered at baseline and after an average of 4.3 years. All incidences of fragility fractures during the study period were confirmed by affected-site radiography. Visceral adipose tissue (VAT) was measured in the android region of a whole-body DXA scan. The mean age was 72.8 +/- 4.7 years, and 28 incident non-spine osteoporotic fractures were identified after a mean follow-up time of 4.3 +/- 0.8 years. According to the Lipschitz classification for nutritional status in the elderly, 38.6 % of women were nonobese (BMI ae 27 kg/m(2)) and 61.4 % were obese/overweight. Logistic regression models were used to estimate the relationship between VAT and non-spine fractures in elderly women. After adjusting for age, race, previous fractures, and BMD, VAT (mass, area, volume) had a significant association with the incidence of non-spine fractures only in nonobese elderly women (VAT mass: OR, 1.42 [95 % CI, 1.09-1.85; p = 0.010]; VAT area: OR, 1.19 [95 % CI, 1.05-1.36; p = 0.008]; VAT volume: OR, 1.40 [95 % CI, 1.09-1.80; p = 0.009]). This study suggests a potential negative effect of visceral adiposity on bone health in nonobese women.
