Résumé

Purpose: Examine the association between physical activity and sedentary time with high sensitivity C-Reactive protein levels in adults with arthritis and fibromyalgia. We also investigated the level of physical activity that was associated with lower clinical levels of high sensitivity C-Reactive protein (< 3 mg/L). Materials and methods: Observational design was used to evaluate the variables of interest based on the Canadian Health Measures Survey cycle 1 to 3 (2007 – 2012). Generalized adjusted additive models were used to explore the shape of the association between high sensitivity C-Reactive protein, daily physical activity, step count and sedentary time. High sensitivity C-Reactive protein was measured with blood samples. Physical activity, number of steps and sedentary time were objectively assessed using an Actical accelerometer. Results: Daily moderate to vigorous physical activity and step count were significantly associated with lower high sensitivity C-Reactive protein levels, but daily light physical activity and sedentary time were not associated with high sensitivity C-Reactive protein levels, even after controlling for age, sex, daily smoking, body mass index, household income, level of education levels, marital status, work year, accelerometer wear time and season. Lower high sensitivity C-Reactive protein levels were associated with 1 to 150 minutes of daily moderate to vigorous physical activity and with daily step counts starting at 4000 in people with arthritis. Adults with fibromyalgia had lower levels of high sensitivity C-Reactive protein when engaging in 10 to 35 minutes of daily moderate to vigorous physical activity and in 5000 to 9000 daily steps. Conclusions: Daily moderate to vigorous physical activity and step count were associated with high sensitivity C-Reactive protein levels that were below the clinical threshold. Given the positive outcomes of physical activity on health, adults with arthritis and fibromyalgia may benefit from these specific recommendations.
