To understand the influencing factors of lumbar disc herniation (LDH) among adult residents of different ethnic groups in Gansu Province, providing foundational data for targeted prevention and control measures.
From May to July 2022,a stratified cluster sampling method was employed based on the altitude of residence (≤1 500 meters, 1 500 to 3 500 meters, >3 500 meters) in Gansu Province. All participants underwent questionnaire surveys, physical examinations, and assessments of blood glucose and lipid levels. A non-conditional binary logistic regression model was used to analyze the influencing factors of LDH prevalence among different ethnic groups.
A total of 4 545 participants were included, with an overall LDH prevalence of 22.8%. The prevalence was highest among the Tibetan population at 30.6%, with significant differences observed among ethnic groups (P<0.05). For the Han ethnic group, a residence duration of less than 36 months, non-drinking, or residing at altitudes of 1 500-3 500 meters were associated with an increased risk of LDH. Conversely, being younger than 30 years, holding a position as a cadre, or residing at altitudes below 1 500 meters were associated with a reduced risk. Among the Tibetan population, low physical activity intensity, an education level of primary school or below, and a residence duration of 24-36 months were linked to an increased risk of LDH, while being male, engaging in low-intensity activities, and being unmarried were associated with a decreased risk. For the Hui ethnic group, a residence duration of 6-23 months or an age range of 30-59 years were related to an increased risk of LDH.
The prevalence of LDH varies among different ethnic groups in Gansu Province, and the influencing factors also differ.
