Personal and workplace factors for the risk of low back pain among institutional caregivers of people with intellectual, autistic or multiple disabilities

Abstract The aims of the present study were to investigate the prevalence of LBP among institutional caregivers of people with intellectual, autistic or associated multiple disabilities and to examine the risk factors for LBP among this population. A cross-sectional, purposive sampling method was used to recruit into the study 1073 staff who were working in 15 disability welfare institutions. The survey materials included an introduction letter, an informed consent, and a structured questionnaire that queried the participant's demographic and working characteristics, healthy lifestyle, and previous and current LBP experiences.

Finally, multiple logistic regression analyses revealed that the factors of female gender (OR = 1.534, p  = 0.039), being married (OR = 1.469, p  = 0.027), being direct care staff (OR = 1.844, p  = 0.025), having fair health status (OR = 1.518, p  = 0.012), or previous (OR = 1.996, p p
