背景:下腰痛(LBP)的残疾和重大经济成本可能会上升,这在巴基斯坦等低收入和中等收入国家是一个基本问题。LBP的相关因素是年龄,性别,包括体育活动在内的种族,高脊柱负荷,提升,弯曲,和扭曲的职业。文献强调,在发展中国家的现有研究中,LBP的相关因素存在实质性差异。目的是调查慢性腰背患者的人口统计学因素和腰椎活动范围与残疾的关系。
方法:在一项为期2020年3月至2021年1月的随机对照试验中,对150名慢性腰背患者进行了基线数据分析,作为分析性横断面研究。在记录了人口统计信息之后,改良-改良Schober试验用于测量腰椎屈伸和Oswestry残疾指数。在对连续变量进行描述性分析后,年龄和疼痛进行Spearman相关性分析。然后在多变量线性回归中拟合在双变量分析中显著的变量。Kruskal-Wallis检验用于分析性别残疾的变化,婚姻状况,工作状态,教育水平,和疼痛的持续时间。0.05的p值是显著的。
结果:结果显示,年龄和坐姿疼痛(rh=-0.189,p=0.021和rh=0.788,p<0.001)与残疾之间存在显着相关性,但没有发现年龄和坐姿疼痛(B=-0.124,p=0.212和B=1.128,p=0.082)对残疾的影响。发现腰椎屈伸的减少会增加残疾(B=-6.018和-4.032,p<0.001)。女性(x2(1)=15.477,p=<0.001)和未婚婚姻状况(x2(1)=4.539,p=0.033)比男性和已婚婚姻状况有更多的残疾,分别。两组之间的疼痛持续时间与残疾有关(x2(2)=70.905,p<0.001)。年龄,教育水平,工作状态无显著性差异(p>0.05)。
结论:女性性别和未婚婚姻状况与功能性残疾有关。腰椎运动范围的减少伴随着更多的残疾,而年龄,教育水平,工作状态对残疾没有影响。
BACKGROUND: The disability and significant economic costs accredited to Low back
pain (LBP) are likely to rise which is an essential problem in low and middle-income countries like Pakistan. The associated factors of LBP are age, sex, and race including physical activity, high spinal load, lifting, bending, and twisting occupations. The literature highlighted there is substantial differences in associated factors of LBP within available studies in developing countries. The objective is to investigate the association of demographic factors and lumbar range of motion with disability in patients with chronic low back.
METHODS: A baseline data analysis was performed as an analytical cross-sectional study among 150 patients with chronic low back in a randomized controlled trial with a duration from March 2020 and January 2021. After recording demographics, Modified-Modified Schober\'s test was used to measure lumbar flexion and extension and Oswestry disability index for disability. After the descriptive analysis the continuous variables, age and
pain were analyzed with Spearman\'s correlation. Variables that were significant in bivariate analysis were then fitted in a multivariable linear regression. The Kruskal-Wallis test was used to analyze variations of disability in gender, marital status, work status, education level, and duration of pain. The p-value of 0.05 was significant.
RESULTS: The results showed a significant correlation between age and
pain in sitting (rh=-0.189, p = 0.021 and rh = 0.788, p < 0.001) with the disability but no significant effects of age and
pain in sitting (B=-0.124, p = 0.212 and B = 1.128, p = 0.082) on disability were found. The decrease in lumbar flexion and extension was found to increase disability (B=-6.018 and - 4.032 respectively with p < 0.001). Female gender (x2(1) = 15.477, p = < 0.001) and unmarried marital status (x2(1) = 4.539, p = 0.033) had more disability than male gender and married marital status, respectively. There was a significance between groups of the duration of
pain regarding disability (x2 (2) = 70.905, p < 0.001). Age, education level, and work status showed no significance (p > 0.05).
CONCLUSIONS: The female gender and unmarried marital status are associated with functional disability. Decreased lumbar range of motion accompanies more disability, while age, education level, and work status do not effect on disability.
