ABSTRACT Practice guidelines recommend addressing obesity for people with knee OA, however, the association of obesity with walking independent of pain is not known. We investigated this association within the Multicenter Osteoarthritis Study, a cohort of older adults who have or are at high risk of knee OA. Subjects wore a StepWatch to record steps taken over 7 days. We measured knee pain from a visual analogue scale and obesity by BMI. We examined the association of obesity with walking using linear regression adjusting for pain and covariates. Of 1788 subjects, the mean steps/day taken was 8872.9 ± 3543.4. Subjects with a BMI ≥35 took 3355 fewer steps per day independent of knee pain compared with those with a BMI ≤25 (95% CI -3899, -2811). BMI accounted for 9.7% of the variability of walking while knee pain accounted for 2.9%. BMI was associated with walking independent of knee pain.

    ABSTRACT: Objectives: The aim of this study is to investigate the impact of obesity on frequency and severity of musculoskeletal pain and quality of life.Methods: Demographic data of 230 patients that presented to the Physical Medicine and Rehabilitation Department because of musculoskeletal pain were acquired and analyzed. Patients were randomized into two groups according to body mass index [BMI] values: obese group [BMI ≥ 30 kg/m2] and normal-weighted group [BMI 2]. Patients were asked for localization and duration of muskuloskeletal pain. Severity of pain was evaluated by using a visual analog scale. Information on difficulties of daily movements within the last month was obtained and quality of life was evaluated by using the Short-Form 36.Results: There was a statistically significant increase in frequency of neck pain [p = 0.049], shoulder pain [p = 0.001], elbow pain [p = 0.006], wrist and hand pain [p = 0.012], arm pain [p = 0.017], low back pain [p = 0.001], hip pain [p = 0.001], knee pain [p = 0.001], ankle-foot pain [p = 0.001], and leg pain [p = 0.001] in the obese group when compared with the normal-weighted group. There was a statistically significant increase in visual analog scale scores of the all body parts in the obese group when compared with in the normal-weighted group [p p p = 0.001].Conclusions: Obesity is a multifactorial, chronic disease which causes many complications and pain on the musculoskeletal system. Difficulty of daily movements also decreases quality of life.
