Acute nonspecific low back pain is prevalent in older adults and generally has a favorable prognosis. The first line of treatment should be non-pharmacological. The aim of the present study was to investigate whether the use of pain medications and satisfaction with care received exert an influence on the intensity of acute low back pain in older adults in a 12-month period.
A longitudinal observational study was conducted with people aging 55 years and older. Older adults with acute low back pain were followed up for 12 months. Pain intensity was measured using the Visual Analogue Scale. Satisfaction with care was self-reported. Generalized estimating equation models were used for longitudinal analysis.
Mean pain intensity was 4.82 points at baseline. Pain was considered moderate in most of the participants, 74% of whom took pain medications and 58% reported being satisfied with treatment. Pain intensity diminished over time. The use of medications was not a determinant in this reduction (OR 0.87 IC95%0.67-1.14) and individuals satisfied with treatment were more likely to have lower pain intensity (OR1.27 IC95%1.01-1.59) after 12 months.
Pain intensity tended to dimmish over a 12-month period, especially in individuals with intense pain. However, this reduction was not influenced by the use of pain medications. Older adults satisfied with the treatment received had a greater tendency toward a reduction in the intensity of low back pain.
急性非特异性下腰痛在老年人中很常见，通常预后良好。一线治疗应为非药物治疗。本研究的目的是调查在12个月期间，使用止痛药物和对所接受治疗的满意度是否会对老年人急性下腰痛的强度产生影响。
对55岁及以上的人群进行了一项纵向观察研究。对患有急性下腰痛的老年人进行了12个月的随访。使用视觉模拟量表测量疼痛强度。对治疗的满意度通过自我报告获得。使用广义估计方程模型进行纵向分析。
基线时平均疼痛强度为4.82分。大多数参与者的疼痛被认为是中度的，其中74%的人服用了止痛药物，58%的人报告对治疗满意。疼痛强度随时间减弱。药物的使用并非疼痛减轻的决定因素（比值比0.87，95%置信区间0.67 - 1.14），并且在12个月后，对治疗满意的个体疼痛强度更有可能较低（比值比1.27，95%置信区间1.01 - 1.59）。
在12个月期间，疼痛强度趋于减弱，尤其是在疼痛剧烈的个体中。然而，这种减轻不受止痛药物使用的影响。对所接受治疗满意的老年人下腰痛强度减轻的趋势更大。
