Paradoxical associations have been observed for leisure-time physical activity (LTPA) and occupational physical activity (OPA) and several health-related outcomes. Typically, higher LTPA is associated with health benefits and high OPA with health hazards. Using data from the Tromsø Study (2015-2016), we assessed how questionnaire-based LTPA and OPA (n = 21,083) and accelerometer-measured physical activity (PA) (n = 6778) relate to pain outcomes. Leisure-time physical activity and OPA were categorized as inactive PA, low PA, and moderate-to-vigorous PA and then aggregated into 9 levels, eg, inactive LTPA/inactive OPA. Accelerometer-measured PA included counts/minute, steps/day, and WHO PA recommendations from 2010 to 2020. Three binary pain outcomes (any pain, any chronic pain, and moderate-to-severe chronic pain) were constructed based on pain location, intensity, duration, and impact on daily activities. By using Poisson regression to estimate absolute and relative associations, we found that high LTPA was associated with lower pain prevalence and vice versa for OPA. Compared to inactive LTPA, prevalence ratio (PR) with 95% confidence intervals was lowest for moderate-to-vigorous LTPA, 0.93 (0.89-0.96) for any pain, 0.88 (0.84-0.93) for any chronic pain, and 0.66 (0.59-0.75) for moderate-to-severe chronic pain. Compared to sedentary OPA, the ratio was highest for moderate-to-vigorous OPA, 1.04 (1.01-1.07) for any pain, 1.06 (1.02-1.10) for any chronic pain, and 1.33 (1.21-1.46) for moderate-to-severe chronic pain. Aggregated LTPA and OPA showed lower outcomes for moderate-to-vigorous LTPA combined with lower levels of OPA. Higher levels of accelerometer-measured PA were associated with less pain. To summarize, we found inverse associations for LTPA and OPA. Benefits from LTPA seem to depend on low levels of OPA.

身体活动悖论;探索与疼痛结果的关系。特罗姆瑟研究 2015-2016 年。


已观察到闲暇时间身体活动 （LTPA） 和职业身体活动 （OPA） 以及一些与健康相关的结果的矛盾关联。通常，较高的 LTPA 与健康益处相关，而高 OPA 与健康危害相关。使用来自特罗姆瑟研究 （2015-2016） 的数据，我们评估了基于问卷的 LTPA 和 OPA （n = 21,083） 和加速度计测量的身体活动 （PA） （n = 6778） 与疼痛结果的关系。闲暇时间身体活动和 OPA 分为非活动性 PA 、 低 PA 和中度至重度 PA，然后归纳为 9 个级别，例如，非活动性 LTPA/非活动性 OPA。加速度计测量的 PA 包括 2010 年至 2020 年的计数/分钟、步数/天和 WHO PA 建议。根据疼痛部位、强度、持续时间和对日常活动的影响构建了三个二元疼痛结局 （任何疼痛、任何慢性疼痛和中度至重度慢性疼痛）。通过使用泊松回归估计绝对和相对关联，我们发现高 LTPA 与较低的疼痛患病率相关，反之亦然。与非活动性 LTPA 相比，中度至重度 LTPA 的患病率 （PR） 和 95% 置信区间最低，任何疼痛为 0.93 （0.89-0.96），任何慢性疼痛为 0.88 （0.84-0.93），中度至重度慢性疼痛为 0.66 （0.59-0.75）。与久坐不动的 OPA 相比，中度至重度 OPA 的比率最高，任何疼痛的比率最高 1.04 （1.01-1.07），任何慢性疼痛的比率为 1.06 （1.02-1.10），中度至重度慢性疼痛的比率为 1.33 （1.21-1.46）。总 LTPA 和 OPA 显示中度至重度 LTPA 联合较低水平 OPA 的结局较低。加速度计测量的 PA 水平较高与疼痛减轻相关。总而言之，我们发现了 LTPA 和 OPA 的负相关。 LTPA 的好处似乎取决于低水平的 OPA。
