BACKGROUND: Musculoskeletal pain alters physiological function, which may be evidenced as early as middle age. Previous research has concluded that middle-aged adults are a high-risk group for musculoskeletal pain and report functional limitations similar to older adults. However, few studies have examined the relationships between musculoskeletal pain and physical function, using objective performance measures in a sample of racially and socioeconomically diverse adults. Thus, this study examined musculoskeletal pain in relation to physical function in middle-aged (30-64 years) White and Black adults and investigated whether the relationship varied by sociodemographic characteristics. METHODS: This cross-sectional examination incorporated data from the Healthy Aging in Neighborhoods of Diversity across the Life-Span Study. Participants (n = 875) completed measures of musculoskeletal pain and objective measures of physical performance (ie, lower and upper body strength, balance, and gait abnormalities). Physical performance measures were standardized to derive a global measure of physical function as the dependent variable. RESULTS: Approximately, 59% of participants identified at least 1 pain sites (n = 518). Multivariable regression analyses identified significant relationships between greater musculoskeletal pain and poorer physical function (β = -0.07, p = .031), in mid midlife (β = -0.04, p = .041; age 40-54) and late midlife (β = -0.05, p = .027; age 55-64). CONCLUSIONS: This study observed that musculoskeletal pain was associated with poorer physical function within a diverse group of middle-aged adults. Future research should longitudinally explore whether chronic musculoskeletal pain identified at younger ages is associated with greater risk for functional limitation and dependence in later life.

PURPOSE: The main purpose of the study was to establish a gait speed cut-off value to predict foot pain and the risk of falls among community-dwelling older adults. PATIENTS AND METHODS: In this cross-sectional study, one-hundred and twenty White older women speaking Croatian (mean ± SD age 71.02 ± 6.78 years, height 161.77 ± 6.23 cm, weight 70.29 ± 12.97 kg, body mass index 26.79 ± 4.42 kg/m2) were recruited. The prevalence of foot pain was assessed by a single-item question and the risk of falls by the Downtown Fall Risk Index with a proposed cut-off value of "low risk" (<3 points) vs "high risk" (≥3 points) of falls. Self-selected gait speed (the independent variable) was estimated with a pressure platform (Zebris Company, Munich, Germany). RESULTS: Mean gait speed was 0.95 m/s. Of the total sample, 53.30% and 33.30% reported foot pain and had higher risk of falls. For foot pain and the risk of falls, gait speed cut-off values were 0.88 m/s and 0.85 m/s (area under the curve = 0.80 and 0.83, standard error = 0.043 and 0.043, p < 0.001). Sensitivity for foot pain and the risk of falls was 66.20% and 85.90% and specificity was 84.80% and 69.00%. Slower gait speed was associated with higher prevalence of foot pain (OR = 10.92, 95% CI 4.28 to 27.89, p < 0.001) and higher risk of falls (OR = 13.59, 95% CI 5.45 to 33.87, p < 0.001). CONCLUSION: Proposed gait speed values of 0.88 m/s and 0.85 m/s may be used in clinical settings to predict foot pain and the risk of falls among community-dwelling older women.
