The purpose of this study was to compare the anaerobic threshold (AT) between subjects with and without non-specific chronic low back pain (NCLBP). The patient group included 15 women with NCLBP. The normal group included 15 women without NCLBP who were age-, height-, weight-, and activity level-matched. The subjects performed a Balke treadmill protocol which was symptom-limited progressive loading test. Their heart rate (HR), ventilatory gas and metabolic equivalents (METs) were measured using the automatic breath gas analyzing system. After the test, each subjects' ratings of perceived exertion (RPE) were evaluated. The visual analog scale (VAS) was assessed pre- and post-test. The independent t-test and Wilcoxon's signed-rank test were used for analysis of the data. Time, HR, the volume of oxygen consumption ($VO_2$), relative $VO_2$, and METs at the AT level of the patient group were significantly lower than those of the healthy group (p<.05). However, there were no significant differences in RPE, VAS, and breathing frequency at the AT level (p>.05). The findings of this study indicate that patients with NCLBP had a lower aerobic fitness than healthy subjects. Thus, implementation of rehabilitation program to increase aerobic fitness may be considered in patietns with NCLBP, and further studies are required to determine the etiological factors of decreased aerobic fitness.

This study was undertaken to review the relationship between middle-school students' food-behavior and their health conditions/school performances. For this purpose, 495 male and female middle-school students were sampled form seven middle schools located in Seoul for a questionnaire survey. The surveyed data were analysed with simple frequency, percentage, t-test, chi-square test, dispersion analysis, Pearson's correlation and hierarchical multiple-regression analysis which make use of the SPSS/PC+ package system. The results of survey can be summarized as follows; Most of students had three meals a day regularly, but some female students used to skip breakfast or supper. The amount of a mael was adequate. Their main night-smacks were fruits. The problem perceived by students was unbalanced meal ; Female students took more snack than that of male students. They usually took a snack a day. All students tended to take delicious snacks. The most favorate smack of students was fruits. Most students did not suffer any serious diseases, but some had one or more respiratory diseases. Female students had some or other physical troubles in their eyes, mouth, digesting organs, muscle/bone, skin and had fatigue. Female students had mental problems of depression, uneasiness and hostility. The average I.Q. of students was 117.4, and those who had higher I.Q. got much higher scores. The regularity and amount of meal and intake of animal food were all positively related with the growth of height and weight. And the taller, the higher I.Q. they had. Those students who took meals three times regularly and adequately, who had no coffee and snack and who took balanced meals were healthier in both physical and mental terms. In particular, those who had adequate amount of breakfast regularly were not only healthier but also had higher I.Q. and school performance.

Effective parenting attitudes have been known to be associated with children's health practices including dietary intake and physical activity. The objective of this study is to compare children's body weights and eating habits by maternal parenting attitudes. Data were collected at school (N = 396; 4th and 5th grade students) using self-administered questionnaires on maternal parenting attitudes, eating habits and physical activity. Parenting attitudes were categorized as 1 of 4 parenting attitudes (overprotective, authoritarian, democratic, and neglectful) using affection and control median cut points. Children's body weights, frequency of breakfast, eating out and fastfood, and physical activity were compared by maternal parenting attitudes. Children's body weights were related with mother's employment status (p < 0.05) and parenting attitudes (p < 0.01). Children of unemployed mothers were more likely to be overweight. Children of neglectful mothers (p < 0.01) were more likely to be underweight, compared with children of mothers with other parenting attitudes. Since, unfortunately, the number of children of neglectful mothers was very limited in this study, we could hardly assess eating habits of children of neglectful mothers. Children of authoritarian mothers ate breakfast more regularly (p < 0.05), but ate snacks less regularly (p < 0.01). Children of democratic mothers ate fastfood less frequently (p < 0.01) and ate snacks more regularly (p < 0.01). Meanwhile, children of overprotective mothers ate breakfast less regularly (p < 0.05) and ate out less frequently (p < 0.01). However, maternal parenting attitudes were not related to children's physical activities. In conclusion, the maternal democratic parenting attitude was associated with healthy eating habits including regular snack time and less fastfood. On the other hand, the maternal neglectful parenting attitude was associated with high risk of children's underweight. Understanding the mechanism through which parenting attitude is related with underweight risk and healthy eating habits may lead to the development of better interventions.

본 연구에서는 남녀 청소년들의 비만도에 따라 자신의 체형을 바르게 인식하고 영양소를 바르게 섭취하고 있는지를 조사하여 그들이 객관적으로 체형을 인식하고 올바른 영양지식을 가지고 자신에게 맞는 에너지를 섭취할 수 있도록 하는데 기초 자료를 제공하고자 시도하였다. 신체적 변화가 급속히 일어나는 일부 청소년을 대상으로 체형인식, 영양지식정도 및 영양소 섭취 상태를 비만도에 따라 조사하였다. 경주시 4개 중학교 남녀학생 총 622명이 본 연구에 참여하였다. 신장, 체중 및 BMI를 구하고, 체형에 대한 인식, 영양지식 및 영양소 섭취상태를 조사한 결과, 남학생의 비만도(17.1%)가 여학생 비만도(14.8%)보다 조금 더 많이 나왔으며, 조사대상자의 자신에 대한 체형인식에서 반 정도만 자신의 체형을 바르게 인식하고 있었고 정상군에서 38% 정도가 과체중 내지 비만이라고 인식하고 있는 것으로 나타났다. 체중조절 경험에 대해서는 여학생의 경우 정상군 및 과체중군 모두 80% 이상이 체중조절 경험이 있었고, 체중조절이 필요없는 저체중군과 정상군의 경우에도 체중조절을 시도했다는 것은 청소년들이 체형에 대해 지나친 관심을 보인 것으로, 성장기에 있는 이들이 정상적인 성장과 건강한 생활을 할 수 있도록 올바른 영양교육이 필요한 부분이라고 생각되어진다.

The purpose of this study is to identify health problems and health behaviors of the middle-aged residing in urban areas and to plan and implement health promotion programs based on their health needs. The subjects' age ranged from 30-64 years in 1.040 middle-aged residing in an area of Kangbook-ku in Seoul. The data were collected from September 1998 to February 1999 with structured questionnaire using face-to-face or telephone interviews. The data were analyzed by SPSS-PC+ and identified by $X^2$ test and ANOVA. The results were as follows: 1. 35.4% of the males and 27.8% of the female responded that they were healthy regarding their perceived health status. In the order of chronic illness prevalence in the case of males was hypertension, diabetes, and digestive disorders and. in the case of females, was digestive disorders, hypertension, arthritis, anemia, and diabetes. 2. Male and female's smoking rates were 7.3% and 3.6% each and marked the highest rate of 30 to 40 years: drinking behavior was 66.9% in males and 32.2% in females. 3. The younger males had the worse dietary habits and had the lowest frequency of regular exercise. The older the females were, the more their weight increased. According to the results, health promotion programs by sex are recommended, especially in the target population of 30 to 40 years. and focused on the strategies for promoting self-care and actual health practice: it is strongly suggested that health promotion programs for adolescent and school-aged children before middle aged health behavior begins.

Objectives : This study was conducted to examine the factors implicated when people start smoking again after a 6 month cessation, and was carried out at the smoking cessation clinic of a public health center. Methods : The study subjects were 191 males who had attended the smoking cessation clinic of a public health center for 6 months in an attempt to quit smoking. Data was collected, by phone interview, regarding individual smoking habits, if any, over the 6 month study period. The factors which may have caused an individual to smoke again were examined. This study employed a health belief model as it theoretical basis. Results : Following a 6 month cessation, 24.1% of the study group began to smoke again during the 6 month test period. In a simple analysis, the factors related to individuals relapsing and smoking again included barriers of stress reduction, body weight gain and induction of smoking by surroundings among perceived barriers factor of our health belief model(p<0.05). In multiple logistic regression analysis for relapsed smoking, significant factors included barriers of stress reduction and induction of smoking by surroundings(p<0.05). The most important reason of for an individual to relapse into smoking was stress(60.9%) and the most likely place for a relapse to occur was a drinking establishment(39.1%). Conclusions : Our results indicate that both regular consultations and a follow-up management program are important considerations in a public health center program geared towards maintaining smoking cessation.

The main object of this study was to understand the body image and body management behavior associated with desiring a thinner and more muscular body. The present study examined whether the drives for thinness and muscularity occur concurrently for both male and female college students, and whether there are gender differences. Moreover, the effects of objectified body consciousness on drive for thinness and drive for muscularity were investigated. A self-administered survey was conducted and a total of 390 data were used for data analysis. Participants included 197 male college students and 193 female students. Results indicated that male students reported significantly lower drive for thinness and higher drive for muscularity than female students. However, the drives for thinness and muscularity were significantly correlated for both male and female college students, and they reported discrepancies between their BMI and self-perceived weight and muscle mass. Findings supported the significant effects of objected body consciousness on the drives for thinness and muscularity for both male and females. Sub-dimensions of objectified body consciousness had differential effects on drive for thinness and muscularity. Specifically, body surveillance and body shame significantly influenced male and female students' drive for thinness, while their control belief did not have significant effects on their drive for thinness. Additionally, body shame emerged as significant unique predictor of drive for muscularity. In terms of gender comparisons, while the effect of body shame was the strongest for the males, the effect of surveillance was as strong as that of body shame for the females.

Purpose: In this study, we provide a way to assess even a slight effect of exercise on trunk-muscle activity. Materials and Methods: Seven healthy male participants (mean age, 24.7 ± 3.2 years; height, 171.2 ± 9.8 cm; and weight, 63.8 ± 11.9 kg) performed 15 sets of an exercise with 20 repetitions of 90° hip and right-knee flexion while lying supine. The exercise intensity was measured using the 10-point Rating of Perceived Exertion Scale after the first and 15th sets of exercises. Although cross-sectional areas and functional T2 mapping using ultrafast imaging (fast-acquired muscle functional magnetic resonance imaging, fast-mfMRI) have been proposed for imaging to evaluate exercise-induced muscle activity in real time, no previous studies have reported on the evaluation of trunk-muscle activity using functional T2 mapping. As a method for assessing trunk-muscle activity, we compared functional T2 mapping using ultrafast imaging (fast-mfMRI) with cross-sectional areas. Results: Although the muscle cross-sectional areas were increased by the exercise, there was no significant difference at rest. On the other hand, for all sets, the changes in T2 were significant compared with those at rest (P < 0.01). These results demonstrate that T2, calculated from fast-mfMRI images can be used to detect even a small amount of muscle activity induced by acute exercise, which was impossible to do with cross-sectional areas. Conclusion: Fast-mfMRI, which can also display functional information with detailed forms, enabled non-invasive real-time imaging for identifying and evaluating the degree of deep trunk-muscle activity induced by exercise.

This study examines the sociodemographic and anthropometric data, health-related and dietary habits, and nutrient intakes according to depression levels in men and women aged over 65 years. A total of 2,938 subjects were analyzed from the 2016~2018 Korean National Health and Examination Survey. Statistical analyses for complex samples were applied using the SPSS software package. Based on the health questionnaire-9, the subjects were applied into two groups. The percentage of depression in women was significantly higher than in men (P<0.001). The factors associated with men's depression were marital status (P<0.05), household income (P<0.001), occupation (P<0.01), and body mass index (P<0.01). Women's depression was found to be significantly associated with household income (P<0.001), education level (P<0.01), basic living allowance (P<0.001), and body weight status (P<0.01). Perceived health status, stress level, quality of life, not feeling very well for the last two weeks, and activity restriction (P<0.001, respectively) were significant health-related habits associated with depression in both sexes. Diabetes (P<0.05) amongst men and hypertriglyceridemia (P<0.01) in women were significant factors associated with depression. Frequency of meals and eating meals together were significant dietary habits associated with depression by sex. Significant associations between improper nutrient intake and depression were also derived for both sexes; 7 nutrients were identified in men and 10 in women. Our results indicate that different factors are associated with depression in the elderly based on sex. Hence, sex-based health promotion programs are required to prevent the onset of depression among the elderly.
