Background: In recent years, obesity in early adulthood has become an urgent global public health concern. Body dissatisfaction may have adverse effects on lifestyle habits, leading to obesity. However, research on nutritional status and body dissatisfaction among Chinese young adults is still insufficient. Therefore, this study aimed to analyze the relationship between body dissatisfaction, dietary habits, physical activity, and nutritional status among university students. In addition, we explored the feasibility of improving university students’ nutritional status by improving the levels of body dissatisfaction. Methods: This study was conducted in Ganzhou City, Jiangxi Province, China, at a randomly selected university. All 1900 undergraduate students volunteered to participate and signed the consent form. Students were required to completed anthropometric measurements and three questionnaires, which included the Physical Activity Rating Scale-3 (PARS-3), Chinese version of the Dutch Dietary Behavior Questionnaire (C-DEBQ), and Body Dissatisfaction. Of these, 1714 students (age: 18–24 years; men: 933, women: 781) with complete and valid data were included. Results: Higher obesity levels were observed in men compared to women (p<0.01). Meanwhile, body dissatisfaction was higher in women compared to men (p<0.01). Overeating and insufficient physical activity were more problematic in women compared to in men (p<0.01). Multiple regression analyses were conducted separately, with BMI and body dissatisfaction as the dependent variables. Body dissatisfaction (β=0.72, p<0.01), muscle mass (β=0.33, p<0.01), emotional eating score (β=0.05, p<0.01), sex (β=-0.05, p<0.05) and physical activity (β=-0.04, p<0.05) score were significant predictors of obesity. Furthermore, Muscle mass (β=0.61, p<0.01), sex (β=0.54, p<0.01), restrained eating score (β=0.25, p<0.01), physical activity score (β=-0.20, p<0.01) and emotional eating score (β=0.08, p<0.01) were significant predictors of body dissatisfaction. Conclusion: The data presented in this study highlight the impact of university students’ body dissatisfaction in China on physical activity deficiency and overeating, discovering that reducing body dissatisfaction has great potential for preventing obesity.

Background. Reliable epidemiologic data on the present burden of hypertension are needed in developing region-specific strategies since previous studies have suggested that China is lagging in risk factor management. Objective. The study aimed at exploring the prevalence of hypertension and its associated factors among adult residents in Ganzhou, China. Methodology. A multistage, stratified, and cluster random sampling method was used to conduct the cross-sectional survey. The study selected four county-level districts in Ganzhou City, China, as the investigation area. Permanent residents aged 18 years who have settled in the area for 6months or more were selected. A total of 7430 residents were involved in the study. Univariate and multivariate logistic regression analysis was carried out to identify predictors of hypertension. Results. The prevalence of hypertension in Ganzhou was 28.5, and the age-standardized prevalence of hypertension was 22.4. Univariate logistic regression analysis revealed that multiple variables have a statistically significant effect on the prevalence of hypertension. The elderly (odds ratio [95 CI]: 2.791 [2.5943.004]), men (1.805 [1.5832.058]), lower educated (0.848 [0.8050.893]), a family history of hypertension (4.575 [3.9005.368]), higher body mass index (1.344 [1.2151.488]), central obesity (1.532 [1.3041.799]), and less vegetable intake (1.150 [1.0231.294]) were the major risk factors for hypertension. Conclusion. Hypertension is a major public health problem in Ganzhou and requires much effort to reduce its prevalence. An effective multifaceted implementation strategy is highly desirable to combat the emerging burden of hypertension.

Background: Quality is the most important factor of satisfaction However, the existing URRBMI index model lacks the decomposition of the connotation of perceived quality and cannot provide a reference for quality improvement and satisfaction promotion.Objective: This study aims to construct a Satisfaction Index Model for Chinese Urban and Rural Residents Basic Medical Insurance (SIM-URRBMI) with accurate and detailed measurement of perceived quality and give a feasible and scientific suggestion for URRBMI or insurance for other countries in the world.Methods: Based on the theoretical framework of The American Customer Satisfaction Index (ACSI), the connotation of perceived quality was refined by literature review and expert consultation to form a pool of alternative measurement variables. A three-stage randomized stratified cluster sampling was adopted to select the main decision makers for pupils’ URRBMI in 8 primary schools from Changsha City. Both Classic Test Theory (CTT) and Item Response Theory (IRT) were used for selection of the measurement variables. The model’s reliability and validity were tested using partial least square (PLS) related methods.Results: A total of 1909 respondents who had insurance for their children were investigated with the initial questionnaire. The revised SIM-URRBMI consists of 11 latent variables and 28 measurement variables with good reliability and validity. Among the three explanatory variables of public satisfaction, perceived quality had the largest total effect (0.737). The variable with greatest effect among the five first-order latent variables on perceived quality was quality of the medical insurance policy (0.472).Conclusions: The revised SIM-URRBMI consists of 11 latent variables and 28 measurement variables with good reliability and validity. It provides accurate assessment of perceived quality, which will greatly help performance improvement. Perceived quality is crucial to public satisfaction, especially, the most important aspects are policies regarding medical insurance reimbursement (basic coverage scope, coinsurance, deductible).
