Objective To assess the prevalence of job burnout among personnel in primary-level institutions for disease prevention and control in Chengdu and to explore potential factors influencing burnout among these staff.

Methods In October 2023, by a convenience sampling method, the personnel from 23 district and county-level disease prevention and control institutions in Chengdu were surveyed with a self-designed "Basic Information Form" and the revised "Maslach Burnout Inventory-General Survey" (MBI-GS). Logistic regression analysis was applied to investigate factors associated with job burnout among the personnel.

Results A total of 441 questionnaires were collected, and 437 were valid, with an effective rate of 99.09%. 319 individuals of primary-level institutions for disease prevention and control in Chengdu had job burnout, with a detection rate of 73.00%, and among them 273 exhibited mild to moderate burnout (62.47%), and 46 exhibited severe burnout (10.53%). The average score of burnout was (2.15 ±1.11). Logistic regression analysis indicated that burnout was significantly associated with age, work interest, and health status. The personnel aged < 30 or 30-39 years had 3.820 times (95%CI: 1.827 to 7.983) and 3.613 times (95%CI: 1.652 to 7.899) the risk of burnout compared to those aged ≥ 50 years, respectively. The personnel with moderate work interest had a 3.968 times (95%CI: 2.262 to 6.961) risk of burnout compared to those with high work interest. Those with poorer health had 4.892 times (95%CI: 1.979 to 12.095) the risk of burnout compared to those in better health.

Conclusions The prevalence of job burnout among personnel in primary-level institutions for disease prevention and control in Chengdu was high. The authorities should focus on the psychological well-being of younger personnel, or personnel with moderate work interest or in poorer health, implement measures to reduce burnout and protect the health of these frontline personnel.
