et al. 2010

OBJECTIVE: To estimate the prevalence and analyze risk factors associated to osteoporosis and low-trauma fracture in women. METHODS: Cross-sectional study including a total of 4,332 women older than 40 attending primary care services in the Greater São Paulo, Southeastern Brazil, between 2004 and 2007. Anthropometrical and gynecological data and information about lifestyle habits, previous fracture, medical history, food intake and physical activity were obtained through individual quantitative interviews. Low-trauma fracture was defined as that resulting from a fall from standing height or less in individuals 50 years or older. Multiple logistic regression models were designed having osteoporotic fracture and bone mineral density (BMD) as the dependent variables and all other parameters as the independent ones. The significance level was set at p<0.05. RESULTS: The prevalence of osteoporosis and osteoporotic fractures was 33% and 11.5%, respectively. The main risk factors associated with low bone mass were age (OR=1.07; 95% CI: 1.06;1.08), time since menopause (OR=2.16; 95% CI: 1.49;3.14), previous fracture (OR=2.62; 95% CI: 2.08;3.29) and current smoking (OR=1.45; 95% CI: 1.13;1.85). BMI (OR=0.88; 95% CI: 0.86;0.89), regular physical activity (OR=0.78; 95% CI: 0.65;0.94) and hormone replacement therapy (OR=0.43; 95% CI: 0.33;0.56) had a protective effect on bone mass. Risk factors significantly associated with osteoporotic fractures were age (OR=1.05; 95% CI: 1.04;1.06), time since menopause (OR=4.12; 95% CI: 1.79;9.48), familial history of hip fracture (OR=3.59; 95% CI: 2.88;4.47) and low BMD (OR=2.28; 95% CI: 1.85;2.82). CONCLUSIONS: Advanced age, menopause, low-trauma fracture and current smoking are major risk factors associated with low BMD and osteoporotic fracture. The clinical use of these parameters to identify women at higher risk for fractures might be a reasonable strategy to improve the management of osteoporosis.

Objective: Vertebral fracture assessment (VFA) is a test technique that can be used to detect asymptomatic vertebral fractures (AVF). It uses dual energy X-ray absorptiometry (DXA) and can be performed concurrently with bone densitometry. This study aims to assess the prevalence of AVF in patients with low bone mass. Methods: Cross-sectional study including 135 individuals with low bone mineral density (BMD) with a T-score < -2.0 standard deviation (SD) in a densitometry clinic located in the city of Blumenau (state of Santa Catarina). Anthropometric, clinical and lifestyle variables were obtained from history-taking and physical examination. Densitometric variables were obtained by bone mineral densitometry and VFA (Explorer, Hollogic ® ). Vertebral fractures were classified according to the Genant criteria. Student's t, chi-square and logistic regression were performed for statistical analysis. Results: AVFs occurred in 24.4% of the subjects. They were older compared to those without AVF (65±9.25 versus 60.1±8.66; p=0.005), and had a history of lowimpact fractures (38.24% versus 19.8%; OR 2.5; p=0.03). Half of the patients that reported steroid therapy had AVFs, compared to one fifth of those who did not use steroids (50% versus 21.49%; OR 3.6; p=0.01). Conclusion: Asymptomatic vertebral fractures were present in approximately one fourth of patients. The risk factors associated were history of low-impact fracture, use of steroids and age > 61 years.

“…This form contains questions related to BS (date of procedure, surgical technique, the smallest weight achieved after surgery), the continuous use of medications by the patient after BS and some specific questions in order to conduct an evaluation by dual-energy X-ray absorptiometry. According to the Brazilian Society for Clinical Densitometry 16 , the use of dual-energy X-ray absorptiometry is not recommended for pregnant women and individuals who have done some x-ray contrast / barium or nuclear medicine two weeks prior to the test.…”

Sarcopenic Obesity is known as a decrease in the quantity and quality of the skeletal muscle mass and increase in fat mass. It can be measured by the residual appendicular skeletal muscle mass (Ap SMM) based on the difference between actual and predicted values. Even though this condition is more common among sedentary elderlies, it may be present in subjects who underwent Bariatric Surgery (BS). We aimed to evaluate the influence of time after BS and physical activity level (PAL) during leisure time on anthropometric parameters, body composition and sarcopenic obesity markers in women. It is a cross-sectional study involving 42 women divided into two groups according to the time since BS and two groups according to PAL. Anthropometric variables, body composition, and sarcopenic obesity markers were assessed. The variables appendicular skeletal muscle mass, height, and fat mass were used to determine sarcopenic obesity markers. Non-parametric numerical tests were used for group comparison and significance level was set at p<0.05. Considering women with sedentary leisure only, those with longer time after BS had higher current body weight and BMI, waist and hip circumference, fat mass, fat-free mass, Ap SMM (equation, residual, and relative) (p<0.05). Considering women with longer time after BS only, sedentary ones had higher current body weight and BMI, waist circumference, fat mass, fat-free mass (relative only), Ap SMM (equation and relative) (p<0.05). Our data indicate that longer time after BS and sedentary leisure modify anthropometric parameters, body composition and sarcopenic obesity markers in women.

Resumo A Obesidade Sarcopênica é associada à diminuição da quantidade e qualidade da massa muscular esquelética e pelo aumento na massa gorda. Ela pode ser medida pela massa muscular esquelética apendicular (Ap MME) baseada na diferença entre os valores reais e preditos. Mesmo sendo mais comum em idosos sedentários, esta condição pode ser verificada em indivíduos submetidos à Cirurgia Bariátrica (CB). O objetivo do estudo foi avaliar a influência do tempo de CB e nível de actividade física (NAF) durante o lazer em parâmetros antropométri
