Low back pain (LBP) is a leading cause of years lived with disability. However, the association of non-chronic LBP with levels of daily physical activity (PA) remains poorly explored. This study investigated the association between previous and current non-chronic LBP with daily PA and compliance with PA recommendations in middle and older-aged adults.
This is a cross-sectional analysis including volunteers from the Baltimore Longitudinal Study of Aging who answered questions about LBP and wore an Actiheart accelerometer for 7days. Generalized linear models and logistic models were used and adjusted for potential confounders.
662 volunteers were included (50.8% women, 68.1% white), aged 68.0 (± 11.4) years. Previous non-chronic LBP was reported by 240 (36.3%) participants with mean pain intensity of 3.5 ± 2.0 (ranging from 0 to 10). Current non-chronic LBP was reported by 5.7% (n = 38) with mean pain intensity of 4.1 ± 2.3. Participants reporting current non-chronic LBP had lower levels of total (β -0.18, 95% CI -0.34 to -0.02) and vigorous (β -0.29, 95% CI -0.56 to -0.007) daily PA and lower odds of meeting PA recommendations (OR 0.20, 95% CI 0.05 to 0.92) compared to those reporting no LBP. No association was observed for LBP intensity. Conversely, previous non-chronic LBP showed no statistically significant association with daily PA levels.
The presence of current non-chronic LBP seems to be negatively associated with PA levels driven mainly by lower engagement in vigorous PA. No association was observed for pain intensity.
腰痛是导致残疾生存年限的主要原因。然而，非慢性腰痛与日常身体活动（PA）水平之间的关联仍未得到充分研究。本研究调查了中老年人既往和当前的非慢性腰痛与日常PA以及PA建议依从性之间的关联。
这是一项横断面分析，纳入了来自巴尔的摩老年纵向研究的志愿者，他们回答了有关腰痛的问题，并佩戴Actiheart加速度计7天。使用广义线性模型和逻辑模型，并对潜在混杂因素进行了调整。
共纳入662名志愿者（50.8%为女性，68.1%为白人），年龄68.0（±11.4）岁。240名（36.3%）参与者报告有既往非慢性腰痛，平均疼痛强度为3.5±2.0（范围为0至10）。5.7%（n = 38）的参与者报告有当前非慢性腰痛，平均疼痛强度为4.1±2.3。与未报告腰痛的参与者相比，报告有当前非慢性腰痛的参与者每日总PA（β -0.18，95%CI -0.34至-0.02）和剧烈PA（β -0.29，95%CI -0.56至-0.007）水平较低，达到PA建议的几率也较低（OR 0.20，95%CI 0.05至0.92）。未观察到腰痛强度与PA的关联。相反，既往非慢性腰痛与每日PA水平无统计学显著关联。
当前非慢性腰痛的存在似乎与PA水平呈负相关，主要原因是剧烈PA参与度较低。未观察到疼痛强度与PA的关联。
