Municipal solid waste workers are at risk of work stress due to physical, environmental, and psychosocial demands. Evidence on individual factors associated with work stress among waste workers in Indonesia remains limited. This study examined the association between individual characteristics and work stress among waste-sorting workers at the Talang Gulo Landfill in Jambi City. A quantitative cross-sectional study was conducted from May to July 2026. All 70 eligible waste-sorting workers were included using total sampling. The independent variables were age, sex, body mass index (BMI), and length of employment. Work stress was assessed using a three-item scale adapted from the stress dimension of the Depression Anxiety Stress Scales-21 (DASS-21). Descriptive statistics summarized respondent characteristics, while Fisher’s Exact Test was used to assess associations at a significance level of p<0.05. Most respondents were female (62.9%) and experienced low work stress (90.0%). The mean age was 46.79±11.16 years, mean BMI was 24.38±3.73 kg/m², and mean length of employment was 6.43±2.71 years. Age was significantly associated with work stress (p=0.021), whereas sex (p=1.000), BMI (p=0.551), and length of employment (p=0.687) were not significantly associated. Age was the only individual characteristic significantly associated with work stress. Occupational health programs may prioritize stress-management education and psychosocial support for younger workers, while further research should investigate broader occupational and psychosocial determinants of work stress.
