The purpose of this study was to investigate if weight-related stimuli had a negative effect on body dissatisfaction levels, and if attentional modification to non-weight-related stimuli could attenuate body dissatisfaction levels. Sixty-one female college students were randomly assigned to a fat word attention-inducing group, a thin word attention-inducing group, and a non-weight word attention-inducing group. We provided a modified visual search task (ie., attention bias modification [ABM] programs) for two sessions at one-week intervals. We also assessed body dissatisfaction levels, affective states, and dietary patterns at pre- and post- session times during the ABM procedure. Only the non-weight word attention-inducing group showed significant reductions in body dissatisfaction but they did not show any changes in affective states and dietary patterns. Participants in the other groups did not show any changes. Results suggest that the non-weight word stimuli could be a non-threatening factor and that inducing attention toward the non-weight words could reduce body dissatisfaction. Implications, limitations, and future directions are discussed. 본 연구에서는 체중관련 자극에 주의를 두는 것이 신체불만족을 촉발시키며 체중과 관련없는 자극에 주의 초점을 맞추는 것이 신체불만족을 감소시키는지 확인하고자 하였다. 61명의 여자 대학생을 모집하여 과체중 관련 단어 주의유도집단, 저체중 관련 단어 주의유도집단, 그리고 비체중 관련 단어 주의유도집단에 무선할당하였다. 이후 시각탐사과제를 응용한 주의편향수정 프로그램을 약 1주일 간격으로 총 2회에 걸쳐 진행하였다. 또한 실험 전, 후에 연구 참여자의 신체불만족 수준, 정서 상태, 섭식 패턴을 측정하였다. 연구 결과, 비체중 관련 자극 주의유도집단에서만 신체불만족 수준이 유의하게 감소하였다. 이들의 정서 상태와 섭식패턴에는 유의한 변화가 없었다. 반면 다른 집단들에서는 어느 측정치에서도 유의한 변화가 없었다. 이는 체중 관련 단서에 주의를 두는 것은 신체불만족에 영향을 주지 않으며, 비체중 관련 자극에 주의 초점을 맞추는 것이 신체불만족을 낮추었음을 의미한다. 즉, 체중 관련 자극은 그 속성에 관계없이 신체불만족을 유지시키는 요인임을 의미한다. 마지막으로 본 연구의 의의와 한계점 및 후속 연구 방향을 논하였다.

이효영,홍보경 대한비만학회 2021 The Korean journal of obesity Vol.30 No.4

Background: Maintenance of proper weight can help protect against chronic diseases. This study investigated the weight control practices of Korean adults and associated factors. Methods: Secondary data from a nationwide cross-sectional survey of the fifth Korea National Health and Nutrition Examination Survey from 2016 to 2018 were analyzed. Subjects were aged 21 to 80 years (n=14,661). The influences of socio-demographic characteristics, health status, health behaviors, and perception of body image on weight control efforts were identified. Results: Women (odds ratio [OR], 1.191; 95% confidence interval [CI], 1.723–2.210), city dwellers (OR, 1.229; 95% CI, 1.097–1.377), those who had a middle school or higher level of education (OR, from 1.281 to 1.525), individuals who perceived themselves to be healthy or in fairly health (OR, from 1.103 to 1.257), those with high blood pressure (OR, 1.244; 95% CI, 1.104–1.401), normal or obese body mass index (BMI; OR from 2.579 to 4.430), non-smokers (OR, 1.373; 95% CI, 1.192–1.582), and those who drank alcohol (OR, 1.174; 95% CI, 1.057–1.305) made more weight loss efforts than other individuals. Regardless of actual BMI, if someone perceived themselves to be obese or normal weight (OR, from 4.324 to 10.884), they made more effort to reduce their weight than those individuals who perceived themselves to be underweight. Conclusion: Weight control is a positive behavior for people with high BMI. However, those individuals with a normal weight who believe they are obese may require further education. It is also necessary to monitor and address the lack of weight control efforts in rural residents and that there is a need for weight control counseling and support for people with high blood pressure and diabetes. Various related causes should be considered and community-wide efforts be made to support people who need weight control.

The purpose of this study was to investigate the effects of circuit weight training and weight training on aerobic capacity and health-related fitness in obese male college students. In this study 16 obese male college students attending G-city University without medical history were selected as subjects. These subjects were randomly assigned to circuit weight training group (n=8) and weight training group (n=8). The subjects in circuit(three circuits using a work-to-rest ratio of 30s:30s) and weight training program performed for 8 weeks, 3 times a week on non-consecutive days at 40 and 80% of one-repetition maximum(1RM), respectively. The maximum oxygen uptake(VO2max) and oxygen uptake(VO2) at anaerobic threshold(AT) were measured as the aerobic capacity. Also, body composition, muscular strength, and muscular endurance were measured and analyzed as the health-related fitness. Based on the results of the study, the following results were obtained. First, the maximum oxygen uptake and oxygen uptake at anaerobic threshold were significantly increased (p<.01) in the circuit weight training group, but there was no significant difference in the weight training group. Second, there was a significant decrease (p<.01) in body weight in the circuit weight training group, and a significant decrease (p<.001) in body fat(%) in both groups. In contrast, lean body mass was increased in both groups, but there was no significant difference. Third, There was a significant difference (p<.001) in muscular strength and muscular endurance in both groups. Therefore, circuit weight training may also be an effective exercise method for increasing potential aerobic capacity and reducing body fat in changes in body composition.

박지용,권태원 한국운동생리학회 2022 운동과학 Vol.31 No.2

PURPOSE: This study aimed to consider the validity of relative weight indices, which are used to compare people of different heights. METHODS: Cross-sectional analyses were conducted using the 2017-2021 “National Fitness Award” in South Korea. Males (n=77,705) aged 18-65 years and females (n=84,641) were included. Three indices [I1=kg/m, I2=kg/m2 , and I3=kg/m3 ] and I4 [I4=kg/ m2 ], which simply reduce the standard error of I1, were analyzed. Pearson's correlation analysis was conducted to determine an index that was highly correlated with weight and was independent of height. Furthermore, an index that was highly correlated with the body fat percentage was considered. The linear relationship between height and the indices was confirmed using regression analysis. The n value of the index (kg/mn), which provides the same value for all height ranges, was derived by regression analysis between weight and height. RESULTS: The correlation analysis between height and the indices described I2 (r=-.009, p<.05) as the most suitable for males. The I1 and I4 (r=-.049, p<.01) were appropriate for females. Weight showed a significant correlation with all indices. The association between body fat percentage and I3 showed a high correlation in both males (r=.722, p<.01) and females (r=.734, p<.01). Regression analyses represented I2 (B=-.005, p<.05) suitability for males. For females, I4 (B=.022, p<.01) was replaceable. CONCLUSIONS: The results of this study suggest that I2 (kg/m2 ) is appropriate for males. The I4 (kg/m2 ) was applicable to females. The I3 (kg/m3 ) showed the strongest correlation with body fat percentage in both males and females.

You, Jeong-Soon,Sung, Min-Jung,Chang, Kyung-Ja The Korean Nutrition Society 2009 Nutrition Research and Practice Vol.2 No.3

This study was conducted to evaluate the effects of a body weight control program with supplementation of sea tangle (20 g/day) on 22 female college students. The contents of the program for 8 weeks contained diet therapy, exercise and behavioral modification through nutrition education. Body composition, dietary habit scores, serum lipid profiles, daily nutrient intakes and the quality of life were assessed at the beginning and at the end of the program. Average age of subjects and height were 20.8 years and 161.9 cm, respectively. After 8 weeks, there were significant reductions in body weight, body fat mass, percent body fat, waist-hip ratio and BMI. The dietary habit score such as a balanced diet, regularity of mealtime, overeating, eating while watching TV or using the computer and eating salty food were increased significantly. Serum lipid levels such as total cholesterol level, LDL-cholesterol level and triglyceride level were decreased but not significantly. There were decreases in intake of energy, protein and fat and increases in intakes of dietary fiber, folic acid, calcium and potassium from the beginning to the end of the program. There were significant improvements on subcomponents of quality of life; physical functioning, general-health and vitality. The limitation of this study was the fact that there was no control group, but an overall evaluation suggests the 8-week body weight control program consisting of diet therapy, exercise and behavioral modification with supplementation of sea tangle would be helpful to improve the body composition, dietary habits, daily nutrient intakes and quality of life in Korean female college students.

박희명(Hi Myung Park),원경화(Kyung Hwa Won),김종석(Jong Suk Kim),김성국(Sung Kook Kim),조미경(Mi Kyung Jo),김항재(Hang Jae Kim),김보완(Bo Wan Kim) 대한내과학회 1991 대한내과학회지 Vol.40 No.4

N/A To evaluate the validity of relative body weight (RBW), body mass index (BMI), and percentage of body fat (%BF) estimated by skinfold-thickness in assessing obesity, comparison of prevalence of overweight assessed by each of these indices was made in 177 men and 148 women aged from 30 to 49 years. The correlation of %BF with RBW and BMI was also studied. The prevalence of overweight assessed by %BF was some- what higher in women and lower in men than those by RBW or BMI. The correlation of %BF with RBW and BMI, as a whole, was significantly high in both sexes with the correlation coefficients of approximately 0.7, reconfirming that these indices are clinically useful. Nonetheless, the correlation of %BF with RBW and BMI was unexpectedly low in those with % BF of more than 20 in men and less than 25 in women. This suggests that both RBW and BMI may be inadequate indices in the assessmant of overweight in those with body weight markedly deviated from the general mean.

[INTRODUCTION] The purpose of this study was to compare health-related fitness, postpartum depression, and body weight changes between two groups of women who had regularly exercised during pregnancy and who had not exercised. This study may also provide useful information for exercise prescription in pregnancy women and contribute their health during pregnancy and physical and mental recovery after delivery. [METHOD] Puerperium women who were being served at the postpartum care center located in B Metropolitan City completed a questionnaire to identify their demographic and delivery-related characteristics. Total 22 puerperium women participated in this study and divided into exercise and non-exercise group. Exercise group (n=9) was those who had regularly exercised for more than 5 months during their pregnancy, while non-exercise group (n=13) was those who had not participated in any exercise program during their pregnancy. Exercise group performed pregnancy yoga program 2 days/week, which was composed of 5-10 min warm-up, 30-40 min main exercise, and 5-10 min cool-down. Submaiximal oxygen consumption, handgrip test, partial curl-ups, back scratch, and body composition were measured for health-related fitness. Postpartum depression was tested using by self-rating depression scale. Difference between the exercise and non-exercise groups was examined by t-test. Difference between the two groups in weight change in accordance with the time point of weight measurement was analyzed by two-way repeated ANOVA. All statistical analyses was peformed by using a statistical software SPSS Ver. 12.0 at the statistical significance level of α=.05. [RESULT] Main Findings of the study were that the exercise group had significantly higher health-related fitness than the non-exercise group, especially in cardiovascular fitness, upper-limb flexibility, and lean body mass. Also, exercise group tended to show lower postpartum depression than non-exercise group, which was not statistically significant. [CONCLUSION] In conclusion, regular exercise during pregnancy was needed to promote the improvement of physical and mental fitness during pregnancy and after delivery. Therefore, it is needed to develop a well-organized and appropriate exercise program during pregnancy for provide pregnant women. [서론] 임심기간 중 규칙적인 운동이 산욕기에 나타나는 신체적·정신적 변화에 미치는 영향에 대해서는 아직 알려진 바 없다. 본 연구에서는 임신기간 중 운동을 한 산모와 하지 않은 산모의 산욕기 건강관련체력, 산후우울, 체중변화를 비교하고 산전운동의 효과를 구명하여 임산부 운동처방의 자료를 제시함과 동시에 임산부의 건강과 출산 후 신체적·정신적 회복에 기여하는 데 있다. [방법] 본 연구의 피험자는 B광역시 D구에 위치한 A병원 조리원에 입실한 산욕부 중 대상자의 일반적 및 분만관련 특성을 설문지를 통해 검사하여 임신 5개월 이후부터 출산 전까지 규칙적인 걷기와 산전 요가프로그램에 참가했던 산모들을 운동군(Exe, n=9)으로 구성하였으며, 그렇지 않은 산모들을 비운동군(Nonexe, n=13)으로 구성하였다. 산전 요가프로그램은 RPE 11-13의 강도로 주 2회, 1시간씩 실시하였으며, 건강관련체력(최대하산소섭취량, 악력, 윗몸일으키기, 백 스크래치, 신체조성), 산후우울, 체중변화를 측정하였다. 연구의 측정결과는 SPSS ver. 12.0을 이용하여 측정항목의 평균값(M)과 표준편차(SD)를 산출하였다. 집단 간 항목별 평균값 차이비교를 위해 t-test를 실시하였으며 체중의 측정시기와 그룹 간 변화를 알아보기 위해 Two-way repeated ANOVA를 실시하였다. 통계적 유의수준은 α=.05로 설정하였다. [결과] 운동군이 비운동군에 비해서 최대산소섭취량, 오른쪽 및 왼쪽 back scratch, 제지방량이 유의하게(p<.05) 높게 나타났다. 근력 및 근지구력은 운동군이 높은 경향을 보였고, 체지방량과 산후우울은 운동군이 낮은 경향을 보였으나 통계적으로 유의한 차이는 없었다. [결론] 연구결과를 종합해 볼 때 신체적․정신적으로 건강한 임신과 출산을 위해 임산부 운동이 활성화되어야 한다고 생각된다.
