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.
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.
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).
PA volume is inversely associated with the prevalence of CBCs.
在人群层面，关于不同类型的体育活动（PA）与慢性背部疾病（CBCs）之间的关联鲜为人知。我们调查了总体及特定类型PA参与水平与CBCs之间的关联。
样本包括60134名年龄≥16岁的成年人，他们参与了1994年至2008年的英格兰健康调查和苏格兰健康调查。使用针对潜在混杂因素进行调整的多重逻辑回归模型，来检验总体及特定类型PA量（步行、家务活动、运动/锻炼、骑自行车、足球/橄榄球、跑步/慢跑、体力劳动和家务）与CBCs患病率之间的关联。
我们发现总体PA量与CBCs患病率之间存在负相关。与不活动的参与者相比，非常活跃的参与者（≥15代谢当量小时/周）经充分调整后的优势比（OR）为0.77（95%置信区间（CI）：0.69 - 0.85）。报告每周进行≥300分钟中等强度活动和≥75分钟高强度活动的参与者，患CBCs的几率分别降低了24%（95%CI：6% - 39%）和21%（95%CI：11% - 30%）。参与高水平体力家务活动的人患CBCs的几率更高（OR = 1.22；95%CI：1.00 - 1.48）。运动/锻炼与CBCs的关联不太一致（例如，低水平运动/锻炼的OR = 1.18（95%CI：1.06 - 1.32），高水平运动/锻炼的OR = 0.82（95%CI：0.72 - 0.93））。
PA量与CBCs患病率呈负相关。
