Abstract
BACKGROUND: Spinal cord injury (SCI) results in severe, permanent functional changes and has become a global health priority due to its high incidence, cost, and disability rate. Current national epidemiological data on SCI in China are limited and outdated. This study aimed to provide a comprehensive, national cross-sectional investigation of SCI epidemiology in China. METHODS: This cross-sectional study included 3055 SCI participants aged 8 to 78 years, conducted from May to September 2023. Data collected encompassed demographic characteristics, employment status, etiology, years lived with disability (YLD), family structure, caregiving status, income, health insurance, paralysis type, and health-related quality of life (HRQoL). Descriptive statistics analyses were used to assess demographic and injury characteristics. Group differences were assessed using t-tests, one-way ANOVA and Chi-square tests. Significant factors were examined using multivariate regression analysis. RESULTS: The majority (88.9%) of respondents were aged 15 to 59 years, with a male-to-female ratio of 2.36:1. Car accidents caused 45.4% of tetraplegia cases, falls caused 35.9% of paraplegia cases, and myelitis was the leading cause of non-traumatic SCI. Among paraplegia participants, 65.5% had complete SCI, while 53.1% of tetraplegia participants had incomplete SCI. Functional improvement was reported by 9.58% of participants. Half (50.3%) of the respondents were unemployed, and 75% had incomes below the national average. HRQoL was significantly lower in the SCI population compared to controls, mainly influenced by injury site, income, age and etiology (p < 0.05). CONCLUSIONS: SCI participants in China exhibit low HRQoL and reemployment rates. Accessible community and vocational rehabilitation programs, alongside robust public medical services, are essential for enhancing reemployment and HRQoL among SCI participants, reducing the overall disease burden.
