Prospective cohort study.
To investigate whether physical performance, grip strength, cognitive function, and depression symptomatology are risk factors for incident low back pain (LBP) over a 2-year period in seniors.
LBP is common in the older age groups, but little is known about predictors of LBP in this age group.
Data from the 2001 and 2003 data collection from the population-based Longitudinal Study of Aging Danish Twins formed the basis of this analysis. Participants free from LBP at baseline (no LBP during the past month, N = 1387) were included and interview data on overall physical function, and assessment of grip strength, overall cognitive function, and depression at baseline were obtained. LBP status at follow-up was assessed using a modified version of the Standardized Nordic Questionnaire. Logistic regression was used to assess the associations between the baseline risk factors and LBP at follow-up.
A total of 1387 persons 70 to 100 years of age at baseline were included in the analyses. Of the initially LBP-free individuals, 7% had experienced LBP more than 30 days out of the past year, 7% had altered or decreased their physical activities due to LBP, and 11% had received treatment for LBP at follow-up. Good overall physical function (being among the top 50%) at baseline was protective for LBP of more than 30 days duration and for diminishing physical activities due to LBP and for care seeking due to LBP. High depression scores (being among the top 25%) were strongly associated with altering or decreasing daily activities because of LBP. Grip strength and overall cognitive performance at baseline were associated with lower incidence of LBP and decreasing activities due to LBP at follow-up; however, these associations were not statistically significant.
Poor overall physical function and depression symptomatology are associated with LBP and consequences of LBP in persons 70 years of age and older.
前瞻性队列研究。
调查身体机能、握力、认知功能和抑郁症状是否为老年人在两年内发生下腰痛（LBP）的危险因素。
LBP在老年人群中很常见，但对于该年龄组LBP的预测因素知之甚少。
基于丹麦双胞胎老龄化纵向研究的2001年和2003年人群数据收集构成了本分析的基础。纳入基线时无LBP的参与者（过去一个月内无LBP，N = 1387），并获取了关于总体身体功能的访谈数据，以及基线时握力、总体认知功能和抑郁的评估数据。随访时的LBP状态使用改良版的标准化北欧问卷进行评估。采用逻辑回归评估基线危险因素与随访时LBP之间的关联。
分析共纳入1387名基线时年龄在70至100岁的人。在最初无LBP的个体中，7%在过去一年中经历LBP超过30天，7%因LBP改变或减少了身体活动，11%在随访时接受了LBP治疗。基线时良好的总体身体功能（处于前50%）对持续超过30天的LBP、因LBP减少身体活动以及因LBP寻求治疗具有保护作用。高抑郁评分（处于前25%）与因LBP改变或减少日常活动密切相关。基线时的握力和总体认知表现与随访时LBP发病率较低以及因LBP活动减少有关；然而，这些关联无统计学意义。
总体身体功能差和抑郁症状与70岁及以上人群的LBP及其后果相关。
