RESUMEN
Objective To investigate the hyperglycemia rate and its correlative factors for the undiagnosed diabetes population in Xuhui District of Shanghai, and to provide the basis for early intervention of diabetes mellitus. Methods Multi-stage cluster sampling was adopted by probability proportionate to size method, and physical examination information and questionnaires were made and collected from 10 130 and 9085 people in 2010 and 2015 respectively from 5 000 households, blood-glucose being examined at the same time.Univariate analysis was made by t test and χ2 test and logistic regression was used for analysis of related factors. Results In 2010 and 2015, the diabetes incidence rate was 2.21% and 1.93% respectively, and the hyperglycemia incidence rate in 2015 was higher than that in 2010 (15.28% vs. 12.63%), both increased with age and BMI value.The rate was higher in those with lower education, abnormal blood pressure, self-reported hypertension, self-reported coronary heart disease and smokers.The logistic regression analysis results showed the incidence of diabetes was positively correlated with age, BMI, abnormal blood pressure and smoking, while the incidence of hyperglycemia was positively correlated with the survey year, sex, age, BMI and abnormal blood pressure; both were negatively correlated with educational level. Conclusion The hyperglycemia incidence rate is high among the community undiagnosed diabetic population.We should focus on high-risk screening for diabetes mellitus, and key intervention of the population with low educational level, overweight and obesity, hypertension and unhealthy lifestyle.
RESUMEN
Objective To investigate the health literacy level and health related behavior of high school students in Xuhui District of Shanghai, and to provide basis for health literacy intervention. Methods Using qualitative and quantitative methods, the quantitative part adopted the multi-stage stratified sampling method.A total of 355 aged 15-18 from senior high schools in Xuhui District were selected for face-to-face survey.The qualitative part adopted the form of group interviews, and 20 students from two senior high schools in Xuhui District were selected for interviews. Results The health literacy level of high school students in Xuhui District was 27.32%, which was lower than that of adults in the same period.Among the three dimensions, the level of basic knowledge and concept literacy was the highest, followed by the level of health basic skills literacy, the level of healthy lifestyle and behavior literacy was the lowest; among the six types of health problems, the level of infectious disease prevention literacy and basic medical literacy was at a low level.Statistical analysis of the correct answer rate showed that the answer rate of various questions in the health literacy survey was quite different.Further analysis of the health-related behavioral characteristics of high school students showed that most students had correct health concept and awareness of health change, but they encountered resistance in the process of knowledge transformation into action, which mainly came from academic burden, school education, peer influence and so on.The main channels for high school students to obtain health-related information were classroom, parents, school and various media.They had a high degree of trust in medical professionals and encountered difficulties in seeking health information. Conclusion The health literacy level of senior high school students in Xuhui District of Shanghai needs to be improved.We should explore a health intervention model more suitable for the behavioral characteristics of this group weak links in their health literacy.
