This study aimed to examine the factors and their age differences associated with low back pain (LBP), including lifestyle and psychosocial factors, among Japanese workers at a large company. The study population consisted of 25,610 workers (mean ± SD age, 44.7 ± 9.6 yr) who underwent annual health checkups and completed the Brief Job Stress Questionnaire (BJSQ) at a Japanese company in 2017. The self-administered questionnaire was used to assess gender, age, occupation, smoking status, exercise status, alcohol intake, job stress, and sleep duration. LBP presence was assessed using a part of the BJSQ. Multivariable-adjusted logistic regression analyses were performed to examine the factors associated with LBP according to age category. The prevalence of LBP in the study group was 23.3%. After stratification by age, overweight status and job stress were found to be significantly associated with LBP in all age groups. However, smoking status was significantly associated with LBP among individuals aged <40 yr (effect of interaction p=0.03) whereas exercise was significantly associated only among individuals aged ≥40 yr (effect of interaction p<0.01). This study shows that LBP factors may differ by age, highlighting the importance of age-appropriate measures for preventing LBP in workers.
本研究旨在调查一家大公司的日本员工中与腰痛（LBP）相关的因素及其年龄差异，包括生活方式和心理社会因素。研究对象为2017年在一家日本公司接受年度健康检查并完成简易工作压力问卷（BJSQ）的25610名员工（平均年龄±标准差，44.7±9.6岁）。采用自填式问卷评估性别、年龄、职业、吸烟状况、运动状况、饮酒量、工作压力和睡眠时间。使用BJSQ的一部分评估是否存在腰痛。进行多变量调整逻辑回归分析，以根据年龄类别检查与腰痛相关的因素。研究组中腰痛的患病率为23.3%。按年龄分层后，发现超重状况和工作压力在所有年龄组中均与腰痛显著相关。然而，吸烟状况仅在年龄<40岁的个体中与腰痛显著相关（交互作用效应p=0.03），而运动仅在年龄≥40岁的个体中与腰痛显著相关（交互作用效应p<0.01）。本研究表明，腰痛相关因素可能因年龄而异，突出了针对不同年龄采取适当措施预防员工腰痛的重要性。
