Physical activity as an indicator of predictive functional disability in elderly

To analyze the time spent on physical activity in female and male individuals as a predictor of the absence of functional disability in older adults, a cross-sectional study was conducted with 624 individuals. Receiver Operating Characteristic curves (ROC) were constructed and compared to areas of physical activity by gender and the absence of functional disability. We identified cutoffs of physical activity (minutes / week) to predict the absence of functional disability (CI 95%). It was found that there is a higher area under the ROC curve for the time spent on physical activities in females. It was observed that 280 minutes / week (women) or 410 minutes / week (men) were the best cutoff points for predicting the absence of functional disability. Time spent on physical activity practices can serve as an important indicator to sort priority groups for certain interventions.To analyze the time spent on physical activity in female and male individuals as a predictor of the absence of functional disability in older adults, a cross-sectional study was conducted with 624 individuals.

Prevalence of disability and associated factors in the elderly

The aim of this study was to estimate the prevalence and factors associated with functional disability in the elderly. The cross-sectional design was used with a sample of 624 individuals, between 60 and 96 years of age. In the assessment of the elderly interviews and physical performance tests were used. In the inferential data analysis, the Poisson regression was used, p≤0.05. The prevalence of disability was 17.6% for Basic Activities of Daily Living and 46.3% for Instrumental Activities of Daily Living. Functional disability for Basic Activities of Daily Living was associated with increasing age, alcohol consumption, depressive symptoms and frailty; the Instrumental Activities of Daily Living were associated with increasing age, illiteracy, multigenerational family arrangement, hospitalization and fragility. The variables that remained in the explanatory model for the decline of functional capacity should be emphasized in proposals for public policies to promote the health of the elderly.

Comparing exercise responses to aerobic plus resistance training between postmenopausal breast cancer survivors undergoing aromatase inhibitor therapy and healthy women

Abstract Background: The aim of this study was to explore whether postmenopausal breast cancer survivors undergoing aromatase inhibitor therapy differ from healthy postmenopausal women in their response to the same aerobic + resistance training. Methods: The participants were separated into two groups: postmenopausal breast cancer survivors undergoing aromatase inhibitor therapy for an average of 20 months (18 women) and healthy postmenopausal women (24 women). We assessed aerobic capacity (predicted maximum oxygen uptake (VO2max) and maximum running velocity test (Vmax)) through a walking test, upper and lower body muscle strength using an estimated one-repetition maximum test, and body composition by dual-energy X-ray absorptiometry at baseline and at three, six, and nine months, respectively. The exercise program was performed three times/week over nine months and consisted of 40 min of machine-based strength training (seated cable row, bench press, leg extension, leg press, and leg curl, as well as bridge, abdominal, and standard plank exercises) followed by 30 min of treadmill walking. Analysis of variance (ANOVA) with repeated measures was used to compare the groups over time. Results: Postmenopausal breast cancer survivors undergoing aromatase inhibitor therapy and healthy postmenopausal women presented similar improvements in estimated lower body strength, predicted VO2max and Vmax, and body fat mass. For maximal upper body strength, there was a significant group x time interaction after six months of training (p = 0.01). The healthy postmenopausal women presented a significant increase in upper body strength after six months, while postmenopausal breast cancer survivors undergoing aromatase inhibitor therapy demonstrated an improvement only at nine months of training. The breast cancer survivors undergoing aromatase inhibitor therapy presented increased lean mass while healthy postmenopausal women maintained values over time (Breast cancer: 33.7 ± 3.9(Pre) vs. 34.1 ± 3.4 kg (Post) and healthy women: 36.4 ± 5.1 (Pre) vs. 36.4 ± 5.0 kg (Post), p = 0.004). Conclusion: Our findings suggest that postmenopausal women undergoing aromatase inhibitor therapy for breast cancer demonstrated adaptations and similar trainability to the same regimen of resistance + aerobic training as healthy postmenopausal women. Implications for Rehabilitation Combined exercise program (aerobic plus resistance) is an important non-pharmacological strategies to improve strength, aerobic capacity, and body composition in breast cancer survivors undergoing aromatase inhibitor therapy. Furthermore, it is important to highlight that the time of intervention seems to influence the upper body strength response in this population. This study showed that trainers and other specialists do not need to modify the prescription of exercise related to healthy women, since the combined exercise program induced similar benefits in strength, aerobic capacity, and body composition in postmenopausal breast cancer survivors undergoing aromatase inhibitor therapy and healthy postmenopausal women.

Relationship between physical activity practice and metabolic profile of postmenopausal women under treatment with aromatase inhibitors for breast cancer

OBJECTIVE To analyze the relationship between physical activity practice and metabolic profile of postmenopausal women under treatment with aromatase inhibitors (AIs) for the treatment of breast cancer. STUDY DESIGN Cross-sectional study, conducted with 101 postmenopausal women (aged 50-80 years). The sample was divided into two groups; group without cancer (GW; n=65) and breast cancer group treated with AIs (GC; n=36). Physical activity (PA) was evaluated by questionnaire. Correlations between physical activity and metabolic variables were made by Pearsons correlation coefficient and the magnitude of these relationships by linear regression. RESULTS In GW, there were observed significant inverse correlations between physical activity and VLDL cholesterol (β=-0.036; 95% CI=-0.068; -0.004); triglycerides (β=-0.036; 95% CI=-0.015; -0.002); glycose (β=-0.029; 95% CI=-0.047; -0.012); and C-reactive protein (β=-0.44; 95% CI=-0.085; -0.003). However, for women under treatment of AIs there was no relationship between physical activity and metabolic variables. CONCLUSION The amount of physical activity practice is inversely related to lipid profile, glucose and C-reactive protein in women without breast cancer. This relation was not observed in the cancer survivors, suggesting that the use of aromatase inhibitors could influence or low intensity of physical activity.

Constructing a logical model in school health: experience on the Lower Amazon region

OBJECTIVE This experience report presents the construction of the theoretical and logic model for intervention to promote physical activity and healthy eating habits of the public schools students in the city of Parintins, Amazonas, Brazil. METHOD We carried out a theoretical research and also a documentary research on the School Health Program (PSE - Programa Saúde na Escola) on the national and local level, in addition to meetings with the PSE management committee for strategic planning of the actions. RESULT The municipality had no systematic structure of health practices at school. A theoretical and logical model that involved prerogatives of practice from the management of the municipality in PSE was developed. Actions to promote physical activity and healthy nutrition of primary and secondary school students were planned and promoted in schools of the PSE. Final considerations: Thus, the collective construction of this proposal contributed to the research of multi-sectoral practices related to the PSE principles and strategies, considering the particularities of the Lower Amazon context.

Effects of resistance plus aerobic training on body composition and metabolic markers in older breast cancer survivors undergoing aromatase inhibitor therapy

Objective To evaluate the effects of combined aerobic + resistance training on body composition and metabolic markers in older breast cancer survivors undergoing aromatase inhibitor therapy. Methods Older breast cancer survivors were randomized to an exercise [resistance + aerobic training]: n = 18, or placebo control group: n = 18. Body composition (measured by DXA) and blood markers of lipid and glucose were measured at baseline, and at 12, 24, and 36 weeks. The exercise group performed 40 min of resistance exercises on machines followed by 30 min of aerobic training on a treadmill, three times per week. Separate 2 (group) × 4 (time) repeated‐measure ANOVAs were used to compare groups over time. Results Significant group × time interactions were found for total and trunk fat mass (p < 0.001 and p = 0.001) and % body fat (p < 0.001), where women in the exercise group lost fat compared to slight gains among women in the stretching control group. There were no significant differences between groups for lean mass, hip or spine BMD, metabolic markers, or CRP. Conclusion Our aerobic + resistance exercise program prevented fat gain, but may not have been sufficient to improve metabolic or bone health markers in older breast cancer survivors undergoing aromatase inhibitor therapy.

Atividade física e estado nutricional: fator de proteção para Doenças Crônicas Não Transmissíveis (DCNT) em idosas?

Objective: To analyze the association of regular physical activity and nutritional status with chronic noncommunicable diseases (NCDs) in elderly women. Methods: Observational and analytical cross-sectional study conducted with a convenience sample of 367 elderly women (60 and over) from the cities of Presidente Prudente, SP and Uberaba, MG, between October/2010 and August/2012. NCDs were identified using a questionnaire based on the Standard Health Questionnaire (SHQ). The International Physical Activity Questionnaire (IPAQ) was used to assess the level of physical activity and anthropometric variables were used to assess the nutritional status. Statistical analysis included the chi-squared test to check for association between physical activity level, according to nutritional status, and the presence of cardiometabolic diseases, and binary logistic regression to test the magnitude of these associations. Results: There was a protective factor against hypertension in active eutrophic women (p=0.024) and sedentary eutrophic women (p=0.032) when compared to the risk group (sedentary and overweight/obesity women); however, this was not observed in physically active overweight women (p=0.734). There was a positive association between sedentary eutrophic elderly women (p=0.047) and the risk for cholesterol. None of the groups were associated with diabetes. Conclusion: Physical activity was not considered a protective factor for hypercholesterolemia, diabetes and hypertension, possibly because of reverse causality given that sedentary women started physical activity after the diagnosis of the disease, which contributed to these results. doi: 10.5020/18061230.2014.p527
