Metabolic Syndrome Prevalence among High School First-Year Students: A Cross-Sectional Study in Taiwan.

Different types of high schools in Taiwan have the same physical education curriculum. In this cross-sectional study, we investigated the difference in the prevalence of metabolic syndrome between senior and vocational high school students. We retrospectively collected health check-up data from 81,076 first-year senior and 68,863 vocational high school students in Taipei City from 2011 to 2014, including their blood pressure, height, weight, waist circumference, fasting blood glucose, total cholesterol, triglyceride, and HDL-c levels. The prevalence of metabolic syndrome was determined using definitions from the Taiwan Pediatric Association (TPA), International Diabetes Federation (IDF), and de Ferranti et al. The prevalence of metabolic syndrome was 1.73% (senior and vocational high school students: 1.22% and 2.33%, respectively) using TPA criteria, 1.02% (0.69% and 1.40%, respectively) using IDF criteria, and 5.11% (3.92% and 6.51%, respectively) using de Ferranti et al. criteria. The most prevalent risk factors overall were increased blood pressure and central obesity. Given the significantly higher prevalence of metabolic syndrome in vocational school students regardless of the criteria, and that metabolic syndrome causes future adult health risks, the physical education curriculum and health education program in vocational schools should be strengthened to decrease the risk and prevalence of metabolic syndrome.

Association between obesity and education level among the elderly in Taipei, Taiwan between 2013 and 2015: a cross-sectional study.

The inverse association between obesity and education level has been demonstrated in many developed countries; however, few studies have investigated obesity in geriatric populations. This cross-sectional analysis explored the association between geriatric obesity and education level, along with other demographic characteristics in Taipei, Taiwan between 2013 and 2015. Taipei citizens ≥ 65 years (aborigines ≥ 55 years) were recruited to participate in the elderly health examination programme. Logistic regression was applied to analyse the relationship between obesity (defined as body mass index ≥ 27 kg/m2 in Taiwan) and education level among men and women after controlling for age, race, income status, and smoking status. A total of 28,092 men and 31,835 women were included in the final analysis. Compared to those with education years ≥ 16, older men and women with education years ≤ 12 had higher odds of being obese. The odds ratios increase as years of education decrease, and the trend is more pronounced among women. Aborigines had much higher chances of being obese among men and women, while there were no differences by income status. The results clarified the factors related to obesity in the elderly, and will be useful for authorities working to improve health outcomes among this population.

Does screening or surveillance for primary hepatocellular carcinoma with ultrasonography improve the prognosis of patients?

PURPOSE: The purpose of this paper is to evaluate the efficacy of ultrasonographic screening for primary hepatocellular carcinoma. PATIENTS AND METHODS: A total of 680 eligible cases were classified into three groups (surveillance, opportunistic, and symptomatic groups) according to their initial exposure. We used survival time, tumor morphology, and T staging as prognostic outcomes. The outcomes of screened/unscreened and sur veillance/nonsur veillance were compared with the use of the logistic regression model. RESULTS: The adjusted odds ratios for the screened group versus the unscreened group, with 1-, 2-, and 3-year survival time being used as outcomes, were 0.33 (95% confidence interval [CI], 0.21-0.52), 0.33 (95% CI, 0.21-0.53), and 0.37 (95% CI, 0.23-0.61), respectively. The adjusted odds ratios for surveillance versus nonsurveillance were 0.58 (95% CI, 0.35-0.97), 0.45 (95% CI, 0.27-0.74), and 0.44 (95% CI, 0.26-0.73). The odds ratios were even smaller when tumor morphology or T stage was taken as the main outcome. All these results were statistically significant. There were significant gradient relationships between prognostic outcomes and extent of screening history. CONCLUSION: The significant impact of ultrasonographic screening on mortality reduction was demonstrated. These findings strongly suggest that early detection of hepatocellular carcinoma by ultrasound may improve the prognosis of patients with hepatocellular carcinoma.
