Abstract: Objective To understand the relationship between marital status and lumbar disc herniation in adult residents in Gansu Province. Methods From May to July 2022, a total of 4598 people were surveyed in Gansu Province by stratified cluster sampling according to altitude (≥3500 meters, 1500~3500 meters, <1500 meters). All subjects were investigated by questionnaire, physical examination, blood glucose and blood lipid test. Univariate analysis and unconditional binary logistic regression model were used to analyze the correlation between marital status and lumbar disc herniation. Results The final effective sample of this survey was 4545 cases. The prevalence of lumbar disc herniation in spouses was 24.49% higher than that in non-spouses, and the difference was statistically significant (P<0.05). Among those with spouses, the prevalence of lumbar disc herniation was higher in women than in men, higher in the <45 age group than in other age groups, and higher in Tibetans than in other ethnic groups, with statistically significant differences (P<0.05). The results of binary logistic regression analysis showed that female, age ≥45 years old, agriculture, forestry, animal husbandry and fishery, workers, other occupations, living altitude ≥1500 meters and hypertension were risk factors for lumbar disc herniation (OR>1). Conclusions The status of spouses of adult residents in Gansu Province is associated with the prevalence of lumbar disc herniation, and the prevalence of spouses is relatively high.
