RESUMEN
PURPOSE: To analyze the associations between pain and physical performance in different aging contexts. METHODS: Data from 1725 older adults from Canada, Brazil, Colombia, and Albania from the 2014 wave of the IMIAS were used to assess the associations between Back Pain (BP) or Lower Limb Pain (LLP) and physical performance by the Short Physical Performance Battery (SPPB). Three binary logistic regression models adjusted for sex, age, study site, education, income sufficiency, BMI, depressive symptoms, and chronic conditions were used to estimate the associations between LLP or BP and SPPB. The SPPB was classified into good performance (8 points or more) and poor physical performance (< 8 points). RESULTS: The mean age of the older men was 71.2 (± 3.0) and the mean age of the women was 71.2 (± 2.8) years. Older men (72.8%, p < 0.05) and women (86.1%, p-value < 0.05) from Albania had the highest frequencies of self-reported general pain. Older women in Colombia had the highest frequencies of LLP or BP (33.5%, p-value < 0.05). In the fully adjusted logistic regression model, LLP or BP was significantly associated with poor SPPB (OR = 0.48, 0.35 to 0.66 95% CI, p < 0.01). CONCLUSIONS: Pain symptoms are associated with reduced physical performance in older people, even when adjusted for other clinical and sociodemographic factors. Protocols for aiming to increase the level of physical activity to manage pain should be incorporated into health care strategies.

BACKGROUND: There is mixed evidence on whether living arrangements and social interactions are associated with poorer health outcomes after hip fracture repair. Distinct social profiles among male and female older adults may explain some of the differences. However, prior studies did not evaluate these differences by sex. This article aims to assess if the associations between living alone, social interaction, and physical performance differ by sex among hip fracture survivors. METHODS: This prospective cohort study is part of the Baltimore Hip Studies seventh cohort, with 168 male and 171 female hip fracture patients assessed at baseline (≤22 days after hospitalization) and at 2, 6, and 12 months post admission. Living arrangements and interaction with children or siblings and others in the past 2 weeks were collected at all visits. Physical performance was measured in the follow-up visits with the Short Physical Performance Battery (SPPB). Linear mixed models tested associations of living alone and social interaction with SPPB over time adjusted for age, education, comorbidities, physical functioning pre-fracture, cognitive function, self-rated health, and time. RESULTS: For men only, living alone was associated with worse performance (0.7 points lower SPPB scores, p = 0.05). Higher social interaction was associated with 0.8 and 1.2 point higher SPPB scores for men and women, respectively (p < 0.05). Visiting with friends was significantly associated with better function among males, while visiting with children or siblings was associated with worse SPPB among females. CONCLUSIONS: Living arrangements and types of social interaction are differentially associated with physical function for older men and women. Screening for social isolation/integration and including interventions that promote social interaction and participation should be considered in healthcare programs for hip fracture survivors.

Objective: To study the extent to which fear of falling (FOF) is associated with the onset of functional disability over a 2-year period in older adults using self-reported and performance-based measures. Methods: In 2012, 1,601 participants (aged 65-74 years) were recruited from four sites: Kingston and Saint-Hyacinthe, Canada; Manizales, Colombia; and Natal, Brazil. They were re-assessed in 2014. We quantified FOF using the Fall Efficacy Scale-International (FES-I; range: 16-64). Functional disability measures were (i) self-reported incident mobility disability, defined as difficulty climbing a flight of stairs or walking 400 m and (ii) incident poor physical performance, defined as a score <9 on the Short Physical Performance Battery. In the Poisson regression analysis, we included only those participants without functional disability at baseline to calculate incident risk ratios in 2014. Results: 1,355 participants completed the 2014 assessment, of which 917 and 1,078 had no mobility disability and poor physical performance at baseline, respectively. In 2014, 131 (14.3%), and 166 (15.4%) participants reported incident mobility disability and poor physical performance, respectively. After adjusting for age, sex, socioeconomic, and health covariates, a one-point increase in FES-I at baseline was significantly associated with a 4% increase in the risk of reporting incident mobility disability (95% CI: 1.02-1.05) and a 3% increase in the risk of developing poor physical performance at follow up in the overall sample (95%CI: 1.01-1.05). Conclusions: FOF is associated with a higher risk of incident mobility disability and poor physical performance in a cohort of older adults. It is increasingly important to study FOF's effect on functional disability and to take necessary measures to prevent the transition to end-stage disability.

OBJECTIVE: Primary care practitioners need simple algorithms to identify older adults at higher risks of falling. Classification and regression tree (CaRT) analyses are useful tools for identification of clinical predictors of falls. DESIGN: Prospective cohort. SETTING: Community-dwelling older adults at 5 diverse sites: Tirana (Albania), Natal (Brazil), Manizales (Colombia), Kingston (Ontario, Canada), and Saint-Hyacinthe (Quebec, Canada). PARTICIPANTS: In 2012, 2002 participants aged 65-74 years from 5 international sites were assessed in the International Mobility in Aging Study. In 2014 follow-up, 86% of the participants (n = 1718) were reassessed. MEASUREMENTS: These risk factors for the occurrence of falls in 2014 were selected based on relevant literature and were entered into the CaRT as measured at baseline in 2012: age, sex, body mass index, multimorbidity, cognitive deficit, depression, number of falls in the past 12 months, fear of falling (FoF) categories, and timed chair-rises, balance, and gait. RESULTS: The 1-year prevalence of falls in 2014 was 26.9%. CaRT procedure identified 3 subgroups based on reported number of falls in 2012 (none, 1, ≥2). The 2014 prevalence of falls in these 3 subgroups was 20%, 30%, and 50%, respectively. The "no fall" subgroup was split using FoF: 30% of the high FoF category (score >27) vs 20% of low and moderate FoF categories (scores: 16-27) experienced a fall in 2014. Those with multiple falls were split by their speed in the chair-rise test: 56% of the slow category (>16.7 seconds) and the fast category (<11.2 seconds) had falls vs 28% in the intermediate group (between 11.2 and 16.7 seconds). No additional variables entered into the decision tree. CONCLUSIONS: Three simple indicators: FoF, number of previous falls, and time of chair rise could identify those with more than 50% probability of falling.

Background: fear of falling (FOF) is a major health concern among community-dwelling older adults that could restrict mobility. Objective: to examine the association of FOF with life-space mobility (i.e. the spatial area a person moves through in daily life) of community-dwelling older adults from five diverse sites. Methods: in total, 1,841 older adults (65-74 years) were recruited from Kingston, Canada; Saint-Hyacinthe, Canada; Tirana, Albania; Manizales, Colombia and Natal, Brazil. FOF was assessed using the Fall Efficacy Scale-International (FES-I total score), and the life space was quantified using the Life-Space Assessment (LSA), a scale that runs from 0 (minimum life space) to 120 (maximum life space). Results: the overall average LSA total score was 68.7 (SD: 21.2). Multiple-linear regression analysis demonstrated a significant relationship of FOF with life-space mobility, even after adjusting for functional, clinical and sociodemographic confounders (B = -0.15, 95% confidence interval (CI) -0.26 to -0.04). The FOF × site interaction term was significant with a stronger linear relationship found in the Canadian sites and Tirana compared with the South American sites. After adjusting for all confounders, the association between FOF with LSA remained significant at Kingston (B = -0.32, 95% CI -0.62 to -0.01), Saint-Hyacinthe (B = -0.81, 95% CI -1.31 to -0.32) and Tirana (B = -0.57, 95% CI -0.89 to -0.24). Conclusion: FOF is an important psychological factor that is associated with reduction in life space of older adults in different social and cultural contexts, and the strength of this association is site specific. Addressing FOF among older adults would help improve their mobility in local communities, which in turn would improve social participation and health-related quality of life.
