Public Health Graduates' Perceptions of the Educational Environment Measured by the DREEM.

Objective: Students' perceptions of the educational environment have a significant impact on their behavior and academic progress. This study aims to measure medical graduates' perception of the educational environment within the School of Public Health at Wuhan University in China. Methods: The survey was conducted by emails sent to 119 graduates, and 93 valid questionnaires were returned. The DREEM was used to assess the medical graduates' satisfaction with the educational environment. Results: The average score on the scale was 126.02 (±18.27). The scoring rate of the areas ranged between 61.06 and 67.11%. The area with the highest score was "perception of teachers." The area with the lowest score was "academic self-perception." No difference was found between genders. Except for "perception of atmosphere," the total scores and other areas showed differences in graduation time. Conclusion: The educational environment at the School of Public Health at Wuhan University was satisfactory. The program contributed to the graduates' later careers. The information obtained in this study identified some areas for improvement.

Fruit and vegetable consumption and risk of cardiovascular disease: A meta-analysis of prospective cohort studies.

A meta-analysis of prospective cohort studies was conducted to examine the relation between fruit and vegetables (FV) consumption and the risk of cardiovascular disease (CVD). We searched PubMed and EMBASE up to June 2014 for relevant studies. Pooled relative risks (RRs) were calculated and dose-response relationship was assessed. Thirty-eight studies, consisting of 47 independent cohorts, were eligible in this meta-analysis. There were 1,498,909 participants (44,013 CVD events) with a median follow-up of 10.5 years. The pooled RR (95% confidence interval) of CVD for the highest versus lowest category was 0.83 (0.79-0.86) for FV consumption, 0.84 (0.79-0.88) for fruit consumption, and 0.87 (0.83-0.91) for vegetable consumption, respectively. Dose-response analysis showed that those eating 800 g per day of FV consumption had the lowest risk of CVD. Our results indicate that increased FV intake is inversely associated with the risk of CVD. This meta-analysis provides strong support for the current recommendations to consume a high amount of FV to reduce CVD risk.

Social Smoking and Mental Health Among Chinese Male College Students.

PURPOSE: China has a high prevalence of smoking, but the characteristics of social smoking in Chinese college students have not been investigated. We examined the pattern of social smoking and explored the association between social smoking and personal cessation efforts and mental health factors among Chinese male college students. DESIGN: Study design was a cross-sectional survey. SETTING: P. R. China was the setting of the study. SUBJECTS: Participants were a random sample of 1327 male college students. MEASURES: All participants completed a self-administered questionnaire that examined their smoking behaviors and a group of specific mental health factors (loneliness, self-harm, suicide, depression, and anxiety). ANALYSIS: Analysis was conducted using descriptive statistics, χ2 analysis, and multivariate logistic regression. RESULTS: Of a total of 207 current smokers, 102 (49.3%) were identified as social smokers. Compared with nonsmokers, social smokers had increased risks for depression (odds ratio, 1.74; 95% confidence interval, 1.15-2.65). Among daily smokers, social smokers were less likely to have an intention to quit smoking than nonsocial smokers (odds ratio, .08; 95% confidence interval, .01-.57). CONCLUSION: This study reveals unique psychologic characteristics related to social smoking. College students are a particular group of interest because unhealthy behaviors initiated during adolescence may continue through adulthood. Our findings provide evidence for future tobacco control intervention among this population.

Urban-Rural Differences in Cardiovascular Disease Risk Factors: A Cross-Sectional Study of Schoolchildren in Wuhan, China.

BACKGROUND: China's rapid population growth and urban migration has developed healthcare inequity across the urban-rural divide. Past studies comparing cardiovascular disease (CVD) risk factor prevalence amongst urban-rural Chinese children are sparse and conflicting. We examined the association between urban-rural residence and risk of offspring CVD in Chinese children. METHODS: A cross-sectional study was conducted in Wuhan, China, during May and June 2010. CVD risk factors include; waist circumference (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), triglycerides (TG), high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, body mass index (BMI), cardiorespiratory fitness (CRF), metabolic syndrome (MetS), and metabolic risk score (MRS). Analysis of covariance and multivariable logistic regression were used to estimate associations between urban-rural residence and offspring CVD risks. FINDINGS: A total of 579 Chinese children (338 boys and 241 girls) aged 9.6 (0.7) years participated in this study. Rural boys had significantly lower CRF and higher FBG, TG, and MRS, while urban boys had significantly higher LDL and DBP. Rural girls had significantly higher BMI, FBG, and TG, as well as lower CRF. Rural children were at increased risks for decreased CRF, elevated MRS, and TG, (OR:2.04, 95%CI:1.29-3.25), (OR:2.33, 95%CI:1.50-3.62), and (OR:2.40, 95%CI:1.62-3.57), respectively. Rural girls and mothers were at increased risks for overweight(OR:7.19, 95%CI:1.64-31.6)/obesity (OR:1.683, 95%CI:1.01-2.82). However, rural boys and fathers were less likely to have overweight(OR:0.62, 95%CI:0.34-1.12)/obesity (OR:0.68, 95%CI:0.48-0.97). CONCLUSIONS: Rural residence was significantly associated with increased CVD risks amongst Chinese children. It is important to provide interventions aiming at China's urban-rural healthcare inequity and community-based approaches that reduce familial CVD risk.

[Quantitative structure-cytotoxicity relationship of anti-HIV 5-phenyl-1-phenylamino-1H-imidazole derivatives].

Both AM1 semi-empirical quantum chemistry method and HF/3-21g* ab initio method were employed to get related parameters or descriptors, particularly, the parameters of the solvation energy delta G with polarizable continuum model, for 42 anti-HIV 5-phenyl-1-phenylamino-1H-imidazole derivatives with known cytotoxicity. With parameters of quantum chemical calculation and traditional ones, 2 multiple linear regression models were obtained. The better regression equation has a high correlation coefficient (r = 0.938) and a low standard deviation (s = 0.125) and the squared correlation coefficient Q2 of the cross-validation is 0.799 (literaure: 0.740) by leave-one-out method. The results have certain significance for the design of new anti-HIV-1 drugs with lower cytotoxicity.
