Back pain beliefs (BPBs) are an important modifiable factor related to disability associated with low back pain (LBP). Back pain beliefs have not been characterized in baby boomers, a group at risk for decreased activity levels and reduced productivity.
The aims of this study were: (1) to identify factors related to BPBs and (2) to evaluate the association between LBP disability and beliefs.
A cross-sectional survey of community-dwelling baby boomers (born 1946-1964) was conducted.
Nine hundred fifty-eight baby boomers (mean age=56.2 years) participating in the Busselton Healthy Aging Study provided their history of LBP, BPBs, LBP behaviors related to care seeking (taking medication, seeking professional help) and activity modification (missing work, interference with normal activities, interference with recreational activities), LBP-related disability, and additional covariates with known associations with BPBs. Regression analyses were used to: (1) identify factors associated with more positive beliefs and (2) test the association between more positive BPBs and lower LBP disability, independent of other correlates of BPBs.
More positive BPBs were associated with younger age, better mental well-being, and higher income, whereas more negative BPBs were associated with receiving sickness or disability benefits and the experience of LBP in the previous month. In participants who reported experiencing LBP within the previous month, more positive BPBs were associated with lower disability scale scores and a decreased probability of interference with usual activities, independent of pain intensity, age, mental well-being, income, and employment status.
Cross-sectional analysis limits assessment of causality.
Poorer BPBs were associated with greater disability. Characterization of the relationships between BPBs and LBP-associated behaviors and disability in baby boomers can assist in developing interventions to improve activity participation and productivity, potentially reducing the burden of LBP in this age group.
背痛信念（BPBs）是与腰痛（LBP）相关残疾的一个重要可改变因素。背痛信念在婴儿潮一代中尚未得到描述，这是一个活动水平下降和生产力降低风险较高的群体。
本研究的目的是：（1）确定与背痛信念相关的因素，以及（2）评估腰痛残疾与信念之间的关联。
对居住在社区的婴儿潮一代（出生于1946年至1964年）进行了横断面调查。
958名参与巴瑟尔顿健康老龄化研究的婴儿潮一代（平均年龄 = 56.2岁）提供了他们的腰痛病史、背痛信念、与寻求治疗相关的腰痛行为（服药、寻求专业帮助）和活动调整（旷工、干扰正常活动、干扰娱乐活动）、与腰痛相关的残疾以及与背痛信念有已知关联的其他协变量。回归分析用于：（1）确定与更积极信念相关的因素，以及（2）检验更积极的背痛信念与更低的腰痛残疾之间的关联，独立于背痛信念的其他相关因素。
更积极的背痛信念与年龄较小、心理健康状况较好和收入较高相关，而更消极的背痛信念与领取疾病或残疾福利以及前一个月的腰痛经历相关。在前一个月报告有腰痛经历的参与者中，更积极的背痛信念与较低的残疾量表得分以及干扰日常活动的可能性降低相关，独立于疼痛强度、年龄、心理健康状况、收入和就业状况。
横断面分析限制了对因果关系的评估。
较差的背痛信念与更大的残疾相关。描述婴儿潮一代中背痛信念与腰痛相关行为和残疾之间的关系有助于制定干预措施，以提高活动参与度和生产力，有可能减轻该年龄组的腰痛负担。
