“…Of confounders, disease burden, cognitive status, depression, and age were cross-sectionally and independently associated with muscle strength and mobility scores in both sexes, consistent with previous studies (17,(58)(59)(60). Note that the causal order of these associations is unknown (e.g., cognitive decline may be the consequence rather than the predictor of the observed physical decline) (61,62).…”

Background: Functional status declines with aging, thus impeding autonomy. Recently, a more even mealtime distribution of dietary protein was positively associated with muscle mass, but the relation of this distribution to physical performance remains unknown. Objective: We examined the relation between mealtime proteinintake distribution and physical performance and its 3-y decline in community-dwelling older adults. Design: Three-year follow-up data from 827 men and 914 women (67-84 y) in the longitudinal study on nutrition and aging [Quebec longitudinal study on Nutrition as a Determinant of Successful Aging (NuAge study); Quebec, Canada] were analyzed. Physical performance, which was measured yearly, was grouped into the following 2 functional composite scores: muscle strength (handgrip, arm, and leg) and mobility (timed-up-and-go, chair stand, and walking speed). Dietary data were collected in 2 sets of three 24-h food recalls at baseline and year 2. The individual mealtime protein distribution was calculated as the CV (i.e., SD divided by the mean) of grams of protein per meal. A mixed model analysis was used to examine trajectories of muscle strength and mobility across time by sex as conditioned by the protein distribution and adjusted for potential covariates. Results: Physical performance deteriorated over 3 y with muscle strength declining more than the mobility score in men (21.51 6 1.68 compared with 20.66 6 2.81) and women (21.35 6 1.77 compared with 20.78 6 2.63) (means 6 SD, P , 0.001). More-evenly distributed protein intake, independent of the total quantity, was associated with a higher muscle-strength score in both sexes throughout followup. It was also associated with a greater mobility score, but only in men and only before adjustment for covariates. Strength and mobility rates of decline were not affected by protein-intake distribution in either sex. Conclusions: In addition to the previously observed association with lean mass, an even distribution of daily protein intake across meals is independently associated with greater muscle strength, but not with the mobility score, in older adults. A longer-term investigation of the role of protein intake and its distribution on physical performance is warranted, as are intervention studies, to support future recommendations.Am J Clin Nutr 2017;106:113-24.

“…Low education level could influence the family income, access to health services and adequate food, resulting in disability 30 and underweight. 31 Work can be a way of preserving physical function/muscle, and field work can promote the maintenance of muscle strength, increased energy expenditure and functional independence.…”

Nutritional status, physical performance and functional capacity in an elderly population in southern Brazil Objective: to investigate the association between nutritional status and functional limitation and disability in an elderly population in southern Brazil. Methods: epidemiological, cross-sectional household-based study carried out with 477 elderly of both sexes (60 to 100 years). Body mass index (BMI) served to assess the nutritional status: underweight (BMI < 22 kg/m²) and overweight (BMI > 27 kg/m²). The sum score (0-5) obtained in three tests: "chair stand" and "pick up a pen" (measured by time) and standing balance (four static measurements) assessed the functional limitation. The disability was evaluated by the difficulty in performing one or more self-reported tasks related to basic activities of daily living (ADLs) and instrumental activities of daily living (IADLs). Crude and adjusted analyzes (3 models) were carried out using Poisson regression; prevalence ratios (PR) and 95% confidence intervals (CI) were calculated. Results: crude analyzes showed a positive association between underweight and functional limitation (PR = 2.71, 95% CI = 1.63 to 4.51); overweight and disability in ADLs (PR = 2.20, CI 95% = 1.44 to 3.35); overweight and disability in IADLs (PR = 1.56, CI 95% = 1.20 to 2.03). The additional adjustments for gender, age, level of education, living arrangements, current work, cognitive function and number of morbidities reduced the strength of the associations, without changing the statistical strength. Conclusion: nutritional status is a factor that is independently and positively associated with functional limitation and disability. We recommend the use of this indicator to monitor the health of the elderly.

“…Thus, the results of this study show differences and similarities with other studies conducted with elderly populations both in Brazil and abroad. These differences among studies that evaluate functional capacity are due to the diversity among populations possibly as a result of the different conditions of life such as type of occupational activity, access to health care services, inequality in income distribution and educational level 11,20,29 . The differences observed in the functional performance of older adults from different localities may be also due to uncontrolled factors and to the lack of standardization among studies conducted in different locations.…”

-The objective this study was to check the association of functional capacity with age and sex in an elderly population. This study is a cross-sectional household survey conducted with elderly people of both sexes enrolled in the Family Healthcare Strategy of Campina Grande, Brazil, from August 2009 to July 2010. Variables were checked for functional capacity (handgrip strength [HS], flexibility/mobility, and balance) and demographic (sex and age). The association of functional capacity with sex and age group was verified by bivariate analysis using Pearson´s chi-squared test (χ2), with the significance set at p <0.05. Were evaluated 420 elderly (68.1% women), whose ages ranged from 60 to 104 years. In the HS test, a higher proportion of both women (45.6%) and men (47.8%) showed regular scores. In the flexibility/mobility test, 63.0% of women and 57.4% of men had a regular score. Balance tests showed a similar percentage in all scores, in both sexes. In the bivariate analysis between indicative variables of functional ability and sex, only flexibility / mobility showed significant association (p<0.05). In the association between markers of functional capacity and age, balance showed a significant association with age in both sexes (p <0.01), and flexibility only in females (p<0.05). The elderly in this study showed satisfactory performance for the variables of functional capacity. There was a significant association of sex only with flexibility. The age group showed significant influence on balance, in both sexes, and on flexibility in women. Key words: Elderly; Flexibility; Muscular strength; Postural balance.

Este estudo é transversal, domiciliar, realizado com idosos, de ambos os sexos, cadastrados na Estratégia Saúde da Família de Campina Grande, PB, de agosto/2009 a julho/2010. Foram verificadas variáveis de capacidade funcional (força de preensão manual (FPM), flexibilidade/mobilidade e equilíbrio) e demográficas (sexo e grupo etário). A associação entre a capacidade funcional o sexo e o grupo etário foi verificada
