Highlights
- • Total physical activity is inversely associated with chronic back conditions.
- • At least 300 min/week of moderate intensity or 30 min/week of vigorous intensity activities are associated with a low odds of having chronic back conditions.
- • Medium domestic activity, football/rugby, or running/jogging are inversely associated with chronic back conditions.
- • High-level manual domestic activity is associated with a higher odds of having chronic back conditions.
- • High-level sport/exercise is associated with a low odds of having chronic back conditions, and low-level sport/exercise is associated with high odds of having chronic back conditions.
Abstract
Background
Little is known about the association between different types of physical activity (PA) and chronic back conditions (CBCs) at the population level. We investigated the association between levels of total and type-specific PA participation and CBCs.
Methods
The sample comprised 60,134 adults aged ≥16 years who participated in the Health Survey for England and Scottish Health Survey from 1994 to 2008. Multiple logistic regression models, adjusted for potential confounders, were used to examine the association between total and type-specific PA volume (walking, domestic activity, sport/exercise, cycling, football/rugby, running/jogging, manual work, and housework) and the prevalence of CBCs.
Results
We found an inverse association between total PA volume and prevalence of CBCs. Compared with inactive participants, the fully adjusted odds ratio (OR) for very active participants (≥15 metabolic equivalent h/week) was 0.77 (95% confidence interval (CI): 0.69–0.85). Participants reporting ≥300 min/week of moderate-intensity activity and ≥75 min/week of vigorous-intensity activity had 24% (95%CI: 6%–39%) and 21% (95%CI: 11%–30%) lower odds of CBCs, respectively. Higher odds of CBCs were observed for participation in high-level manual domestic activity (OR = 1.22; 95%CI: 1.00–1.48). Sport/exercise was associated with CBCs in a less consistent manner (e.g., OR = 1.18 (95%CI: 1.06–1.32) for low levels and OR = 0.82 (95%CI: 0.72–0.93) for high levels of sport/exercise).
