BACKGROUND: Back pain is a popular disease in general population as well as in workers. School students handle heavy bag and keep awkward postures during class long time. However, the prevalence of back pain among students and the risk factors associated with back pain are not well known. METHODS: In this study, we assess the frequency of risk factors for back pain among 2,717 high school students. From April 2001 to May 2001, using a self-reported questionnaire, we collected data on occurrence of back pain and potential risk factors for back pain. RESULTS: Fifteen percent of high school students reported having daily back pain for a week or more during the past 12 months. Female students had a higher prevalence of back pain than males(OR=2.22, 95% CI 1.69-2.91). Using a multiple logistic regression model, we found six factors associated with back pain for females; alcohol(OR=1.75, 95% CI 1.26-2.45), depression(OR=1.75, 95% CI 1.84-2.28), poor physical health(OR=2.57, 95% CI 1.84-8.58), obesity(OR=0.29, 95% CI 0.12-0.68), exercise(OR=l.50, 95% CI=1.07-2.16), and good performance(OR=l.50, 95% CI 1.05-2.18). Only alcohol, however, associated with back pain for males(OR=1.70, 95% CI 1.05-2.77) CONCLUSIONS: High school students had a relatively high prevalence of back pain. Students with alcohol consumption had the higher risk for back pain.

Objectives : This study characterized the extent to which youth depressive symptoms, parental alcohol problems, and parental drinking account for differences in alcohol-related problems among a large sample of adolescent females. Methods : The stratified sample consists of 2077 adolescent females from twelve female-only high schools located in a large metropolitan city in the Republic of Korea. Students completed a questionnaire about alcohol use and alcohol problems, their parents' alcohol problems, and a number of risk and protective factors. Data were analyzed using tobit regression analyses to better characterize the associations among variables. Results : Almost two-thirds of students who consume alcohol had experienced at least one to two alcohol-related problems in their lives and 54.6% reported at least one current symptom of depression, with nearly one-third reporting two depressive symptoms. Two-thirds of the students indicated that at least one parent had an alcohol-related problem, and that approximately 29% had experienced several problems. Results of tobit regression analyses indicate that youth alcohol-related problems are positively associated with depressive symptoms (p<0.01) and parent drinking problems (p<0.05). Parental drinking is no longer significant when the variable parental attention is added to the model. Decomposition of the tobit parameters shows that for every unit of increase in depressive symptoms and in parent drinking problems, the probability of a youth experiencing alcohol problems increases by 6% and 1%, respectively. For every unit of increase in parental attention, the probability of youth experiencing drinking problems decreases by 5%. Conclusions : This study presents evidence that alcohol-related problems and depressive symptoms are highly prevalent among adolescent females. Although a comprehensive public health approach is needed to address drinking and mental health problems, different interventions are needed to target factors associated with initiation of alcohol problems and those associated with increased alcohol problems among those who already began experiencing such problems.

This study was assessed the menu satisfaction and preferences of high school boarding students in Gyeongggido. Data collection was carried out through surveys given to 300 high school boarding students; a total of 274 were usable. Statistical analyses were done using the SAS package program (version 8.2 for Windows). The results of this study are summarized as follows: 54.0% of respondents were freshman and 46.0% were sophomores: and 52.9% of respondents were male and 47.1% were female. According to the results of the menu satisfaction survey, males and females significantly differed on appropriate food temperature, freshness of food, harmonic combination of menu, menu variety, quality of ingredients, appearance of food, and frequency of supplied nutrition information. A significant difference regarding menu satisfaction was also found between grade level. First grade students were more satisfied than second grade students. Moreover, menu preferences were significantly high for omelet-rice, fried rice, pork-on-the-bone soup, deep-fried chicken, fruit salad, spicy chinese cabbage salad kimchi, chinese cabbage kimchi, and all desserts. On the other hand, pumpkin and rice porridge, beef and rice porridge, barley rice, soft tofu stew, soybean paste soup, braised japanese spanish mackerel, and sauteed squash were not significantly preferred. The results showed that high school boarding students' menu preferences differed depending on gender, grade, and boarding period. In conclusion, the results of this study should provide dieticians information for improving menu planning. In addition, foodservice satisfaction of the boarding school students can be improved by continuous menu improvement.

Objectives: Stress during adolescence is related to undesirable nutritional intake and negatively affects the growth and development. This study was performed to investigate the relationship among life stress, dietary behaviors and the intake of high-fat containing snacks in male and female high school students in Gyeonggi-do area. Methods: The subjects were 700 high school students (350 males, 350 females) in Gyeonggi-do from July to September 2014 and the survey was performed by using questionnaire that included general characteristics, dietary behaviors, high-fat containing snacks intake, and daily life stress. Results: There was a gender difference in health-related life style and dietary behaviors, and the life stress was significantly higher in female students than in male students. For health-related life style, exercise frequency, hours of sleep and conversation time with parents had significantly negative correlations with life stress, while smoking and perceived stress had significantly positive correlations with life stress. For dietary behaviors, the frequency of eating-out had a significantly negative correlation with life stress, while the changes in amount of meal intake under stress had a significantly positive correlation with life stress. The fat intake of 'high-stress group' was significantly higher and high-fat containing snacks consumed by this group consisted of cookies, honey bread and fried foods. Conclusions: It is necessary to develop appropriate programs for the emotional stability and stress relief of adolescents that provide continuous nutrition education focused on proper snack intake, desirable dietary behaviors and nutritional aspects.

This study investigated attitudes and behaviors related to family meals among middle and high school students. Furthermore, it evaluated the dietary quality of family meals as compared to meals eaten alone. The data were collected between March and May, 2006, from 353 male and female students attending middle and high schools in Seoul and Gyeonggi-do, using pre-tested self-administered questionnaires. The following results were obtained. In terms of family meal frequency, 44.0% of the middle school students ate with their family 'more than once per day', and 19.3% participated in family meals 1 or 2 times per day. However, only 16.4% of the high school students had family meals 'more than once per day', and 32.9% participated in family meals '1 or 2 times per a week', showing a significant difference between the groups (p<0.001). Fifty-nine percent of the middle school students answered they ate with their family everyday or on week days, whereas 67.8% of the high school students had family meals only on holidays (p<0.001). The nutrient intakes of those participating in family meals were compared to the intakes of those who ate meals alone. For both males and females, calorie intake was higher for those who ate family meals. Animal protein intake was significantly different (p<0.001) between groups, with the results showing a two-fold higher intake for those eating family meals as compared to meals alone. In addition, the intake of animal fat was significantly higher in the family meal group (p<0.001); however, plant-based fat intake was higher in the meal alone group.

Objectives: The objectives of this study were to assess the implementation status of Health Promoting Schools (HPS) among elementary, middle and high schools and to identify characteristics of the schools that affect the implementation of HPS. Methods: A total of 703 teachers (male 32.2%, females 67.8%) from 70 elementary, middle and high schools in Seoul and Gyeonggi participated in the survey. A 60-item self-evaluation questionnaire was used to assess implementation status of HPS. Results: Implementation of HPS in elementary schools were more favorable than middle and high schools after controling for participants' characteristics, such as age, gender, and their duties at school (<0.001). Being a private school was associated with higher score on implementation of HPS in both elementary (${\beta}$=0.170) and middle/high schools (${\beta}$=0.275). However, being located in rural areas (${\beta}$=-0.409) and having larger number of students (${\beta}$=-0.521) were associated with lower score on implementation of HPS in middle/high schools. Conclusions: Middle and high schools, especially large public and/or rural schools, were less favorable in implementing HPS. Therefore, supporting those schools are necessary and developing evaluation and monitoring system for HPS implementation will contribute to promote students' health.

Polyclonal antiserum R101 against aflatoxin $B_1$ ($AFB_1$) was raised in New Zealand white rabbits after injection of bovine serum albumin-$AFB_1$ conjugate. Competitive ELISA (enzyme linked immuno-sorbent assay) demonstrated that antiserum R101 has the highest binding for $AFB_1$ (50% inhibition at 170 fmol) and aflatoxicol II (50% inhibition at 112 fmol). It also reacts with other aflatoxins such as $AFB_2$, $AFG_1$, $AFG_2$, and aflatoxin metabolites ($AFM_1$, $AFM_2$, $AFP_1$, and $AFQ_1$), but it does not cross-react with $AFG_2a$. Using this antiserum, aflatoxins were quantitated in 100 urine samples of undergraduate students at the College of Pharmacy, Sung Kyun Kwan University, Republic of Korea. By ELISA, $AFB_1$ and its metabolites were detected in human urine samples (N=100, male=89, female=11, ages=20~31 yrs) with a range of 1.4~200.6 ng/kg/day (mean$\pm$SD=$18.11{\pm}33.01\;ng\;AFB_1/kg/day$ in males, $3.82{\pm}2.65\;ng/kg/day$ in females). Assuming that urinary excretion is about 7.6% of $AFB_1$ intake (Groopman et al., 1992), we estimated that Koreans were daily exposed to a total dietary $AFB_1$ of $240.20{\pm}438.67\;ng/kg/day$ in males and $50.35{\pm}29.88\;ng/kg/day$ in females, respectively. When the human monitoring data was applied to a linear regression model of Y=21.67X-10.04 {Y=liver cancer incidence per 100,000, X=Log $AFB_1$ intake (ng/kg/day), r=0.99} developed from previously reported epidemiological data, calculated liver cancer incidences attributed to $AFB_1$ exposure were 41.56/100,000 in males and 26.84/100,000 in females. The incidences were similarly correlated with liver cancer mortality rates of 43.43/100,000 in males and 11.23/100,000 in females in Korea. These results suggest that aflatoxin exposure may be an important risk factor for the high incidence of liver cancer in Korea.
