Objectives: More than half of youth smokers start to use cigarettes in their middle-school ages. Thus, middle school students should be the primary target population for smoking prevention education although the technical smoking rate is higher in high school students than in middle school students. Based on this significance, this study examined personal and social factors reinforcing non-smoking middle school students to acquire positive attitudes on smoking cigarettes. Methods: A total of 1,081 students of the 3 middle schools in Seoul participated in the self-administered survey. The designated schools were conveniently selected and all the 2nd-grade students of the schools participated in the survey. The questionnaire asked reinforcing social factors of smoking such as, family and parental history of drug use, close-people's smoking and drug use, personal experience of drug use, perceived smoking and drug use knowledge and attitudes, perceived smoking intention in future, and other delinquent behaviors. Results: Personal experience of drug and delinquent behaviors, perceived smoking intention in future, perceived knowledge of smoking, educational experience, and close-people's smoking and drug use were significantly related to students' attitudes on smoking. The significant factors affecting the positive attitudes of smoking were living with broken family and few education experience of smoking in school as social factors and strong smoking intention in future, high score of delinquent behavior, and low score of drug use knowledge as personal factors. Conclusions: Adolescents' strong smoking intention and little smoking education experience would primary personal and social factors reinforcing positive attitudes on smoking. Thus, school-based educational programs preventing smoking intention need to be developed and to be delivered to middle school students to minimize the future smoking population in a long-term perspective.

The elderly is a target group for health functional foods (HFFs). We surveyed 825 Korean elderly (71.4- years-of-age) for HFF use and significant variables for HFF use including demographic characteristics, health related variables, and nutritional beliefs. The prevalence of HFF use was 48.7%, and among all types of HFF, red ginseng products were eaten most frequently, followed by ginseng products, nutritional supplements, and mushroom products. The mean age of users of HFFs was lower than nonusers (p<.01). HFFs were eaten more frequently by subjects from families living with a spouse or unmarried children (p<.01) and those with higher levels of monthly pocket money (p<.001). HFFs were also eaten more frequently by subjects or their spouses with a higher education level (p<.001). The social activity participation ratio (p<.01) of subjects and the HFF usage ratio by the spouse (p<.001) were higher in users of HFF than in nonusers. Dietary assessment scores were not different between the two groups, and users had a more positive view concerning the potential health benefits of HFFs than did nonusers (p<.001). Most users of HFF ate HFFs "when they were healthy" (52.2%) and experienced some effect through HFF use (45.8%). Most users of HFFs received information on HFFs through their families or relatives (38.1%) and most purchased HFFs at the pharmacy or oriental medicine clinic (44.8%). HFF users preferred multivitamin- and Ca-supplements most among the vitamin and mineral supplements belonged to HFFs. The above results show that HFF use is widely spread among subjects, and that use of HFF is influenced by various factors. Thus, practical guidelines for HFF use should be provided for the elderly through elderly focused-nutrition education based upon significant variables and consumption behaviors for their HFF use of present study.

We surveyed 848 university students, $21.4{\pm}2.5$ years of age, attending university in Seoul, Kongju, Chongyang-Gun in the Chungnam province of Korea, for their use of health functional foods (HFF) and for significant variables in this use, namely demographic characteristics, health related variables, dietary variables and nutritional beliefs. The prevalence of the use of HFF was 33.6%. Among all types of HFF, nutritional supplements were taken most frequently, followed by (in order) red ginseng products, apricot extract products and ginseng products. HFF use was higher in females (p<.05), in subjects living in a dormitory (p<.05) and those from families with a relative high socioeconomic status (p<.001). Self-health concern (p<.05) and usage ratio of HFF by family (p<.001) was higher in users than in nonusers of HFF. The total score of dietary assessment was higher in users than in nonusers of HFF (p<.001), and users had a more positive point of view concerning the potential health benefits of HFF than did nonusers (p<.001). Most users took HFF when they were healthy (37.2%) or when they were sick (27.4%). They did not feel special effects through the HFF use (49.8%). Most users got the information about the specifics of HFF from family and/or relatives (55.8%). Most of users confirmed nutrition facts when they purchased the HFF (70.9%), but a considerable number of users could not understand these nutrition facts (48.1%). Users preferred vitamin C- and Ca-supplements most among vitamin mineral supplements belonged to HFF. These results show that the use of HFF is common among university students. As well, the use of HFF by students is affected by various variables. Supplementary nutritional education should be undertaken among university students, in order to give them a reasonable guideline for the use of HFF, based upon influencing factors and usage behaviors that we learned from this survey.

The purpose of this study was to examine what factors affected patients who suffered from essential hypertension compliance with health behaviors, to help build a successful strategy to step up their compliance with health behaviors, and to seek effective ways to implement health education programs for patients with chronic disease. The subjects in this study were 60 people selected from among the patients who were diagnosed by physicians as having essential hypertension in S General Hospital in the city of P from April 10 through July 30, 2000, after health education was provided four times a month. The quasi- experimental design based on a control group pretest-posttest design was employed. The subjects were divided into three groups of 20 patients each： one was an experimental group to receive education in one-to-one interview, another was an experimental group to receive education as a group, and the third was a control group. The two experimental groups learned the same material through different methods, and the control group was given the same teaching materials and asked to comply with health behaviors on their own without instruction. After the three-week education was implemented in different ways, their compliance with health behaviors was measured. Collected data was analyzed by t-test, paired test, one-way analysis of variance, correlation analysis and regression analysis procedures. The findings of this study were as follows： 1. Concerning the effective type of health education, the group education produced the best results, followed by the one-to-one interviews and the sole use of print media. 2. Regarding the effect of compliance with health behaviors, the group- educated group got the highest score in compliance with health behaviors, but blood pressure lowered more significantly in the individual interview group. And the compliance with health behaviors had a significant negative correlational relationship with both systolic and diastolic blood pressure. 3. Parameter that had most significant correlational relationship with compliance with health behaviors was health locus of control, followed by self-efficacy and health perception. But there was no significant correlational relationship between compliance with health behaviors and knowledge of hypertension. 4. As a result of analyzing the impact of knowledge of hypertension, health locus of control, self-efficacy and health perception on compliance with health behaviors, self-efficacy was found to exercise most influence. Above-mentioned findings suggested that group education or one- to-one discussion would be more effective for health care for hypertension in koreans, as they could serve to have patients realize their own responsibility for health and to motivate their compliance with health behaviors, and there was a need to more positively utilize educational intervention for patients with chronic diseases, which could elevate not only compliance with health behaviors but self-efficacy.
