The purpose of this study was to analyze the prevalence of sugar-sweetened beverage (SSB) consumption among residents aged 18–64 in Beijing and to identify associated influencing factors. A cross-section study was conducted from June 1, 2024 to May 31, 2025, including 10,409 residents aged 18–64 in Beijing. Logistic regression was applied to examine demographic, behavioral, and knowledge-related factors associated SSB consumption. 

Findings: The overall prevalence of SSB consumption was 38.7%. After adjusting for demographic factors, infrequent checking nutrition labels when purchasing food, infrequent active weight monitoring, dining out/taking out food >1 day/week, moderate-intensity physical activity less than 300 minutes a week, lack of knowledge about SSB, and awareness of the health risks of SSB were the risk factors for SSB consumption. 

SSB consumption among Beijing adults remains high. Men, urban residents, and younger adults represent priority groups for intervention. Strengthening nutrition education, improving health literacy, and promoting healthier dietary behaviors are essential strategies to reduce SSB consumption and improve population health.
