Relationship between Physical Activity and Pain in U.S. Adults

We sought to assess the relationship between physical activity (PA) and pain within the available sample, with secondary aims to assess prevalence of pain, PA levels, health care seeking behaviors, and impact of pain on daily activities and work.

We conducted an epidemiological cross-sectional observational study utilizing National Health Interview Survey data from 2020. We examined the self-reported adherence to current PA guidelines and the prevalence of pain. We hypothesized those dealing with pain were less likely to meet PA guidelines. The PA levels, pain prevalence, frequency, and intensity were assessed via the survey and relationships explored via modeling.

Of 31,568, 46% were men and 53.99% women with mean age of 52.27 yr (±17.31 yr). There were 12,429 (39.37%) participants that reported pain on some days, 2761 (8.75%) on most days, and 4661 (14.76%) every day. The odds of engaging in PA decreased in a stepwise fashion based on frequency and intensity of pain reporting when compared with no pain. Importantly, PA is a significant correlate affecting pain reporting, with individuals engaging in PA (strength and aerobic) demonstrating two times lower odds of reporting pain when compared with those not meeting the PA guidelines.

There is a significant correlation between meeting PA guidelines and pain. Meeting both criteria of PA guidelines resulted in lower odds of reporting pain. In addition, the odds of participating in PA decreased based on pain frequency reporting. These are important findings for clinicians, highlighting the need for assessing PA not only for those dealing with pain but also as a potential risk factor for minimizing development of chronic pain.
