ABSTRACT
Objective To understand the prevalence of obesity among primary and middle school students in Taizhou, and provide scientific evidence for prevention and control. Methods A primary school, a middle school and a high school were randomly selected from each of 9 counties(cities or districts)in Taizhou using stratified sampling. We collected data on height, weight and age to calculate body mass index(BMI)and evaluated it according to the Appendix A of Technical Specification for Student Health Examination(GB/T 26343-2010)"Screening Standards for Overweight and Obesity in Children and Adolescents". Descriptive statistics of obesity was conducted. Results The prevalence of obesity among primary, middle, and high school students in Taizhou was 8.08%. It was higher among boys(10.80%)than girls(5.08%)(P < 0.05). The trend of obesity significantly decreased among students in different schools was as follows:primary school > middle school > high schoolt(χboy2 = 259.309, P < 0.001; χgirl2 = 244.679, P < 0.001), regardless of sex. Conclusion Obesity among primary, middle, and high school students in Taizhou remains high, with an increasing trend in recent years. The targeted population for prevention and control is 7-12-year-old primary school students, especially boys.
ABSTRACT
AIM: To investigate the status of myopia in students from different kinds of schools in Shantou city, China. METHODS: In this cross-sectional study, 2 418 students from 4 middle and high schools in Shantou were surveyed through randomized cluster sampling. Ophthalmic examination and auto-refraction were performed for all subjects. RESULTS: Among all 2 394 students examined. The myopia rates for students from middle and high school were 48. 07% and 68. 28%. In normal middle school, students from rural area had lower rate of myopia than students from the urban area (χ2 = 13. 879, P CONCLUSION:The prevalence of myopia in the middle school of urban area in Shantou was higher than rural area. The increasing rate of myopia in youngsters is correlated with study stress. In order to decrease the myopia rate, it is extremely important to improve study environment in students.
ABSTRACT
The purpose of this study was to determine the factors related to eating breakfast for middle and high school students in Seoul using the Theory of Planned Behavior. Out of 2,280 questionnaires distributed to 22 schools, 2,060 were returned (90.4% response rate) and 1,899 were analyzed (83.3% analysis rate). Gender, self-perceived household income level and mother's working status were examined as demographic factors. "Attitude", "Subjective norm", "Perceived difficulty in access to breakfast", "Perceived time restriction" and "Self restriction to breakfast" were extracted as psychosocial factors as the results of factor analysis and reliability test using 17 items. In case of middle school students, boys were more likely to skip breakfast than girls. The students perceiving their household income level "low or middle low" were more likely to skip breakfast than those who perceived their household income level "high or middle high". The students whose mother had a job tended to skip breakfast than those whose mother had no job. In case of high school students, the students perceiving their household income level "low or middle low" tended to skip breakfast than those perceiving their household income level "high or middle high". The results of analysis of variance, all the psychosocial factors examined in this study-"Attitude", "Subjective norm", "Perceived difficulty in access to breakfast", "Perceived time restriction" and "Self restriction to breakfast"- were related to the frequencies of eating breakfast during weekdays in both the middle and high school students.

The purpose of this study was to determine factors affecting intention to participate in school breakfast programs of middle and high school students in Seoul using the Theory of Planned Behavior. Out of 2,280 questionnaires distributed to the middle and high school students, 2,060 were returned (90.4% response rate) and 1,799 were analyzed (78.9% analysis rate). To determine factors affecting intention to participate in school breakfast programs, logistic regression analyses were conducted for middle and high school students, respectively. For logistic regression, data of 1,217 out of 1,799 students (637 middle and 580 high school students) were used after excluding 582 students which had an answer 'Not sure' to the question about intention to participate in school breakfast programs. In case of middle school students, male than female students (OR = 1.504), the students who skipped all breakfast (OR = 1.851), who ate breakfast 1~2 times (OR = 3.474) or 3~4 times (OR = 1.950) than those who ate breakfast everyday during weekdays of the previous week were more likely to participate in school breakfast programs. In case of high school students, male than female (OR = 1.967), the students who skipped all breakfast (OR = 4.187), the students who ate breakfast 1~2 times (OR = 3.024) or 3~4 times (OR = 2.095) than those who ate breakfast everyday during weekdays of the previous week were more likely to participate in school breakfast programs. In addition, both possibility of middle and high school students' participation in school breakfast programs increased as the satisfaction with school lunch service (OR = 1.704, 1.653) increased. Middle school students who perceived their household income level 'low or middle low' (OR = 1.999) than those who perceived their household income level 'middle' and the students who had more positive 'attitude' (OR = 1.311) toward eating breakfast were more likely to participate in school breakfast programs. However, high school students who had higher 'perceived difficulty in access to breakfast' (OR = 1.370) were more likely to participate in school breakfast programs. The results of this study could be useful data to plan and develop school breakfast programs in Korea.
