Esophageal cancer typically lacks specific early symptoms, leading to late-stage diagnosis and poor prognosis, with an overall low 5-year survival rate. However, early detection and timely intervention can significantly improve the 5-year survival rate, underscoring the importance of prevention, screening, and early intervention. Short video platforms are increasingly utilized for health communication, offering opportunities to disseminate medical knowledge. However, the quality and reliability of health-related content, particularly for diseases like esophageal cancer, remain under explored. This study aimed to systematically evaluate the quality, reliability, completeness, and engagement of esophageal cancer-related videos on three popular short video platform: Bilibili, TikTok, and Kwai, to identify platform-specific strengths and limitations in disseminating health information. A total of 311 esophageal cancer-related videos were analyzed. Video assessment was assessed using 4 standardized scoring framework including General Quality Scores (GQS) for general quality, the DISCERN for reliability, Completeness Score (CS) for comprehensive information, Engagement Score (ES) for understandability and entertainment value of the video. Video features (source, category, content), user’s behavior (likes, shares, comments) were also collected. Cross-platform comparisons were conducted to identify disparities in content quality and user interaction. This study analyzed 311 esophageal cancer-related videos on Bilibili, TikTok, and Kwai. Video quality varied significantly across platforms, with Bilibili showing the highest DISCERN (5.46), GQS (2.97) and CS (3.64), while TikTok videos achieved the highest ES (2.88) and engagement metrics (e.g., likes and collections, p < 0.001). Kwai videos had the lowest scores across all measures. Content focused primarily on “symptoms” and “treatment,” with Bilibili offering more comprehensive coverage. Correlation analysis revealed a positive association between video quality and engagement on Bilibili but a negative association on TikTok (e.g., GQS and likes, r=-0.251, P = 0.009). The quality of esophageal cancer-related videos across Bilibili, TikTok, and Kwai is suboptimal, with notable quality disparities among the platforms. Users on platforms other than Bilibili show limited ability to identify or prefer higher-quality content. This study underscores the potential of short-video platforms for esophageal cancer public health education, but highlights the need for improvements in content quality, ethical standards, and platform governance to address health equity concerns.

Many studies have examined the association between socioeconomic status (SES) and mental stress. Uncertainty stress is a prominent aspect of mental stress. Yet no research has ever empirically analyzed the impact of SES on uncertainty stress. Students were identified through a multistage survey sampling process including 50 universities. Each student participant completed the Global Health Professions Student Survey (GHPSS) on Tobacco Control in China. Regional variables were retrieved from the National Bureau of Statistics database. Both unadjusted and adjusted methods were considered in the analyses. Among the 11,942 participants, severe uncertainty stress prevalence was 19.6%, while severe life stress prevalence was 8.6%. Multilevel logistic regression showed that most SES variables were associated with uncertainty stress. Students with “operation and commercial work” as mother’s occupation and “rural or township” as family location exhibited a higher prevalence of severe uncertainty stress. Lower family income and original region gross domestic products (GDP) were also associated with higher severe uncertainty stress prevalence. However, only father’s occupation was correlated with life stress. Based on the literature review, this is the first empirical study examining the impact of SES on uncertainty stress in China and elsewhere in the world. Our research underscores the importance of decreasing socioeconomic inequalities in controlling excessive uncertainty stress.

This study will examine explanatory variables including socioeconomic inequalities related to mental stress at both the individual and regional level. A cross-sectional multistage sampling process was used to obtain participants. Data on mental stress and individual socioeconomic status were gathered via face to face interview. Regional variables were retrieved from a national database. Multilevel logistic regression analysis was used to assess socioeconomic variances in mental stress. Among the 16,866 participants, 27.2% reported severe levels of mental stress (95% CI: 19.4%-35.1%). Multilevel regression analysis indicated that lower individual educational attainment and income, and lower regional Per Capita GDP was associated with mental stress. The results also indicated that managers, clerks, and professional workers manifested higher stress levels than those in other occupations. Based on the results of this study individual and regional socioeconomic inequalities in China are associated with mental stress.

Many studies have examined childhood and adolescent obesity, but few have examined young adults and the effect of their home and current living environments on prevalence rates. The present study explores contextual factors affecting overweight and obesity among university students in China and, in particular, focuses on how the SES–obesity relationship varies across different geographical contexts. Participants were 11,673 students, who were identified through a multistage survey sampling process conducted in 50 universities. Individual data was obtained through a self-administered questionnaire, and contextual variables were retrieved from a national database. Multilevel logistic regression models were used to examine urban and regional variations in overweight and obesity. Overall the prevalence of overweight and obesity in the study sample was 9.5% (95% CI 7.7, 11.3%). After controlling for individual factors, both attributes of the home location (regional GDP per capita and rurality) and the current university location (city population) were found to be important, thus suggesting that the different origins of students affect current levels of obesity. At the individual level, while students with more financial resources were more likely to be obese, the extent of this relationship was highly dependent upon area income and city size. The results of this study add important insights about the role of contextual factors affecting overweight and obesity among young adults and indicate a need to take into account both past as well as present environmental influences when considering the role of contextual factors in models of the nutrition transition.

Second hand smoke (SHS) exposure is a severe public health problem, especially in low and middle countries, but no studies have examined both individual and city-level variables influencing exposure. A cross-sectional multistage sampling design was used to survey subjects from 21 cities in China. Using a standardized questionnaire individual level information was collected. City-level variables were retrieved from the National Bureau of Statistics database. Multilevel logistic regression analysis was used to assess SHS exposure variation at both the individual and city level. SHS exposure prevalence among non-smokers was 28.1 % (95 % CI 27.1–29.0). At the individual level lower educational attainment and income and higher exposure to tobacco advertising were associated with higher SHS exposure. On the other hand richer cities, and those with more anti-smoking media news coverage, had less SHS exposure. The presence of city smokefree regulations was unrelated to exposure. Given its human and economic costs, reducing SHS exposure should receive greater priority than it does in China. The results point to the need for the enactment of national smokefree laws in order to combat unacceptably high levels of SHS exposure.
