A Study on Perceived Weight, Eating Habits, and Unhealthy Weight Control Behavior in Korean Adolescents

유난숙 대한가정학회 2011 International Journal of Human Ecology Vol.12 No.2

This study compared actual weight with perceived weight, described the prevalence of unhealthy weight control behavior, determined the differences in psychological and personal variables between participants that reported unhealthy weight control behavior and those who did not, and examined the relationship of eating habits to unhealthy weight control behavior for Korean adolescents. The study population consisted of a nationally representative sample of middle and high school students who completed the Fifth Korea Youth Risk Behavior Web-based Survey (KYRBWS): Fifth in 2009. Among the 75,066 participants of KYRBWS, 35,473 (n = 18,851 girls and 16,622 boys) were eligible for a research focused on unhealthy weight control behavior. The results of this research were as follows: First, there were considerable discrepancies (45.1% of girls and 32.8% of boys) between the perceived weight and the actual weight. Second, overall, unhealthy weight control behavior was more prevalent in girls and fasting was the most commonly reported behavior. Third, participants that reported unhealthy weight control behavior scored significantly lower on scaled measures of happiness, health, academic achievement, and economic status; in addition, they scored higher on stress measures. Fourth, girls and boys shared common protective factors of having breakfast and vegetables more often, perceiving their weight as underweight rather than overweight, and having a correct weight conception. Protective factors unique to girls were having lunch and dinner more often. Girls and boys shared common risk factors of the consumption of soda, fast food, instant noodles, and snacks more often, while consumption of fruit more often was a risk factor only for girls. The improvement of protective factors and minimization of risk factors through Home Economics classes (and other classes relevant to health) may mitigate unhealthy weight control behavior of adolescents.

비만환자의 조혈모세포이식 후 체중 적용 기준에 따른 Tacrolimus 초기 농도 비교

이수진,배진아,권지은,이연지,윤정이,강진숙 한국병원약사회 2021 병원약사회지 Vol.38 No.2

Background : Tacrolimus is an immunosuppressive agent and is largely used to prevent graft-versus-host disease in hematopoietic stem cell transplantation patients. Tacrolimus requires therapeutic drug monitoring because of its narrow therapeutic range. The number of cases where the dose of tacrolimus was reduced in obese patients because the blood concentration was higher than the initial effective therapeutic range (10–15 ng/mL)is increasing. Therefore, this study attempted to assess the adequacy of early tacrolimus dosages and establish more suitable weight-based dosing strategies for obese patients. Methods : This was a retrospective study, conducted on patients 20 years of age or older who received tacrolimus from the day before transplantation from January 2019 to June 2020 in Seoul St. Mary’s Hospital. The blood concentration of tacrolimus in the actual body weight (ABW) group was obtained from the actual blood collection, from which patient-specific pharmacokinetic parameters were obtained. The expected blood concentration of tacrolimus in the ideal body weight (IBW) group was then calculated. To evaluate the adequacy of the tacrolimus dosage, the average blood concentration and the number of patients within the effective therapeutic range were investigated. To evaluate the risk of developing side effects and the reduction in therapeutic effects, the number of patients above and below the effective therapeutic range and their average tacrolimus level were compared based on ABW and IBW, respectively. Results : The average blood concentration of 74 patients was 18±5.7 ng/mL in the ABW group and 14±4.5 ng/mL in the IBW group (p<0.001). The number of patients within the effective therapeutic range was 22 (29.7%) in the ABW group and 35 (47.3%) in the IBW group (p=0.043). The number and average tacrolimus level of the patients above the effective therapeutic range were 50 (67.6%) and 20.6±5.1 ng/mL, respectively, in the ABW group and 25 (33.8%) and 19.1±3.5 ng/mL, respectively, in the IBW group. The number and the average tacrolimus level of patients below the effective therapeutic range were 2 (2.7%) and 8.8±0.7 ng/mL, respectively, in the ABW group and 14 (18.9%) and 8.7±1.0 ng/mL, respectively, in the IBW group. There was no statistical difference in the average tacrolimus levels of the patients above and below the effective therapeutic range (p=0.190 and p=0.908, respectively). Conclusion : In obese patients, the administration of tacrolimus based on IBW is more preferred than ABW-based administration. However, additional pharmacokinetic model studies are needed.

Objectives: Perception types of body shape affects weight control. Appropriate understandings of actual body has a good effect on weight control, but misunderstanding of actual body condition is the opposite, which further has a negative impact on physical, mental health and so on. The purpose of this study is to examine the factor of affecting on weight control experiences by perception types of body shape. Methods: This study used data from the Korean Health and Nutrition Examination Surveys(KNHANES) Ⅵ, conducted in 2013-2015. Subjects were 8,509 aged more then 19 years, categorized as normal/normal perception, obesity/normal perception, normal/obesity perception, obesity/obesity perception according to perception types of body shape. Results: The factors affecting weight control experiences differ between perception types of body shape. For normal/normal perception type, affecting factors of weight control experiences were sex, age, education, marriage, physical activity and self-rated health. For obesity/normal perception type, affecting factors were education level, physical activity and self-rated health. For normal/obesity perception were only sex and self-rated health. For obesity/obesity perception type, affecting factors were sex, education level, drink, physical activity and self-rated health. Conclusions: The difference factors that influence weight control experiences by perception types of body shape suggest that there is a difference in motivation attempting to weight control by perception types of body shape. Therefore, it is necessary that the perception types of body shape should be considered when constructing an individual weight control plan or an obesity management education and prevention.

Agreement Between Actual and Perceived Body Weight in Adolescents and Their Weight Control Behaviors

신선미 대한비만학회 2017 The Korean journal of obesity Vol.26 No.2

Background: To investigate the agreements between actual and perceived body weight status among adolescents and to identify the associations of disagreements with their weight control behaviors. Methods: This study used the secondary data of a sample survey (n=13,871) of the Seoul Student Health Examination among middle and high schools in 2010. Agreements between actual (underweight, normal, overweight, and obese, according to 2007 Korean National Growth Charts) and perceived body weight status (underweight, normal, overweight, and obese) were examined using Chi-square and Cohen’s kappa agreement, and then multinomial logistic regression including gender, grade, and attempt of weight control or method of weight control was done. Results: Agreements between actual and perceived body weight status were only 45.2%, and disagreements were up to 54.8%, including mild over- (20.4%), severe over- (1.8%), mild under- (29.5%), and severe under-estimation (3.1%). The kappa coefficient of agreement was only 0.19. The odds ratios on severe over-estimated perception were 1.59 (95% CI, 1.22-2.07) in female subjects, 1.78 (95% CI, 1.36-2.34) in diet control behaviors, and 1.53 (95% CI, 1.18-2.00) in exercise. The odds ratios on severe under-estimated perception were only 0.40 (95% CI, 0.32–0.50) in female subjects but 5.77 (95% CI, 3.68-9.06) in taking medication. Conclusion: There were associations of body weight control behaviors with disagreements of actual and perceived weight status. Therefore, further study is needed to identify the weight disagreement-related factors and to promote the desired weight control behaviors for adolescents.

서지현(Seo, Jihyun),마혜선(Ma, Hyesun),김성희(Kim, Sunghee),김지영(Kim, Jiyoung),신민서(Shin, Minseo),양윤정(Yang, Yoon Jung) 한국영양학회 2016 Journal of Nutrition and Health Vol.49 No.3

본 연구는 제5기 국민건강영양조사를 이용하여 만 19~64세 성인 10,608명을 대상으로 BMI를 기준으로 분류한 체형과 주관적 체형인식의 차이를 기준으로 실제 체형보다 마르게 인식하는 RL군, 실제 체형을 올바르게 인식하는 RA군과 실제체형보다 비만하다고 인식하는 RH군으로 분류하여 각 그룹의 영양소 섭취, 체중조절 여부, 정신건강상태를 비교하였다. 1) RH군의 비율은 19~29세, 30~49세, 50~64세에서 남자는 12.1%, 9.5%, 10.0%였고, 여자는 31.2%, 29.0%, 20.3%로 여자에서 RH군의 더 비율이 높았고, RL군의 비율은 남자 19~29세, 30~49세, 50~64세에서 26.0%, 24.2%, 28.8%였고, 여자는 3.9%, 5.7%, 14.6%로 남자에서 RL군의 비율이 더 높았다. 2) 남녀 연령대별 BMI에서 남자 19~29세, 30~49세의 평균 BMI는 RA군이 가장 높고 RH군, RL군 순위였으며 50~64세에선 RL군이 가장 낮았다. 여자 19~29세에서는 RL군이 가장 낮았으며, 30~49세, 50~64세에선 RA군이 가장 높고 RH군, RL군 순이었다. 3) 남자의 경우 19~29세에서 탄수화물 섭취량은 RH군이 가장 낮게 섭취하였다. 여자는 30~49세에서 총에너지 섭취량은 실제체형보다 비만하게 인식하는 RH군이 에너지 섭취가 가장 낮았으며 RL군이 가장 많이 섭취했다. 여자 30~49세와 50~64세에서 탄수화물 섭취량이 RH군에서 가장 낮았고 총에너지 섭취량에 따른 탄수화물 섭취비율 또한 30~49세에서 실제체형보다 비만하게 인식하는 RH군에서 가장 낮아 실제체형보다 비만하게 인식하였을 때 탄수화물 섭취량이 적었으며 이로 인해 에너지 섭취량이 적었다. 4) 남자 50~64세를 제외한 남녀 모든 연령대에서 실제체형보다 비만하게 인식하는 RH군이 체중 감량 시도를 가장 많이 한 것을 알 수 있고, 남자 19~29세, 30~49세, 전 연령대의 여자에서 실제체형보다 비만하게 인식하는 RH군에서 체중이 증가한 경우가 가장 적었지만, 주별 중등도 운동일수에는 차이가 없어서 체형인식과 운동량은 관련이 없었다. 5) 남자 19~29세에서 실제체형보다 비만하게 인식하는 RH군이 우울감을 느낀 비율이 높았지만, 남자 50~64세에서는 실제체형보다 마르게 인식하는 RL군이 우울감 경험비율과 스트레스가 높아 체형인식에 따른 우울감은 남성에서 연령별로 차이를 보였다. 결론적으로 본 연구를 통해 성별과 연령에 따라 다소 차이가 있지만 실제체형보다 자신을 비만하다고 인식할 때 탄수화물의 섭취를 줄이고, 체중조절을 더 시도하며, 젊은 남성들에서 우울감 경험률이 높음을 알 수 있었다. 이에 따라 올바른 신체상을 확립하기 위해선 마른 몸매 선호에 대한 왜곡된 사회문화적 분위기를 개선하고 자신의 체형에 대한 올바른 인식이 필요함을 확인하였다. Purpose: The objective of this study was to examine the effect of the body shape discordance, the difference between true body type based on body mass index (BMI) and self-recognized body image, on nutrient intake, weight control attempt, and mental health in Korean adults. Methods: Subjects were persons aged 19~64 years (4,382 men and 6,226 women) who participated in the 2010~2012 Korea National Health and Nutrition Examination Survey. Subjects were categorized as RL (Group recognized as lighter than BMI criteria), RA (Group with agreement between BMI criteria and self-recognized body image), and RH (Group recognized as heavier than BMI criteria) according to the difference between actual body type based on BMI and self-recognized body image. Results: Means of BMI in RH groups were lower than or equal to that of RA groups in all groups. No significant differences in total energy intake were observed among the three groups in men, but total energy intake was higher in the RL group than in the RH group in 30~49 year old women. Proportion of carbohydrate was the highest in the RL group among 30~49 year old women. RH groups paid more attention to weight control and had less weight gain than other groups. Higher proportions of depressive symptoms were reported in the RH group in 19~29 year old men, while a higher proportion of depressive symptoms were reported in the RL group in 50~64 year old men. Conclusion: The current findings suggest an association of perceiving body shape with energy intake, weight control attempt, or depressed mood in some age groups. Body image perception can influence eating, weight control attempt, and depressed mood, therefore proper body image perception should be established in Korean adults.

백혈병 비만환자의 체중 적용 기준에 따른 항암치료 효과 및 안전성 비교

박지인,이유경,구은형,이소희,박애령,윤정이,강진숙,박실비아 한국병원약사회 2023 병원약사회지 Vol.40 No.1

Background : There are no clear guidelines for setting anticancer drug doses in obese hematological cancer patients. Based on the reports that toxicity will not increase significantly, the weight application criteria for chemotherapy dose in acute leukemia was changed from the adjusted body weight (AdjBW) to the actual body weight (ABW) in August 2020. In this study, we compared the efficacy and safety between the AdjBW and ABW groups and evaluated the appropriateness of the criteria change. Methods : From January 2019 to June 2021, the study was conducted on obese acute leukemia patients at Seoul St. Mary’s Hospital. The efficacy between the AdjBW and ABW groups was compared; whether each group reached complete remission (CR) and mortality within 30 days and recurrence within 6 months. The safety was evaluated by analyzing the recovery period of absolute neutrophils and platelets, bacteremia occurrence, and hospitalization period. Results : There were no significant differences in the CR rate (84.6% vs 76.5%, p=0.502), mortality within 30 days (0% vs 4.8%, p=0.206), and recurrence within 6 months (6.7% vs 21.1%, p=0.24) between the groups after induction of chemotherapy. Recovery period of absolute neutrophils (21.51±4.2 days vs 20.69±6.48 days, p=0.412) and platelets (27.02±10 days vs 30.11±27 days, p=0.409), bacteremia occurrence (70.8% vs 56.9%, p=0.109), and hospitalization period (28.46±6.84 days vs 26.41±7.4 days, p=0.117) were not significantly different between the two groups, but the number of neutropenic fever was higher in the ABW group (1.60±1.08 times vs 1.12±0.89 times, p=0.01). Conclusion : Preemptive anticancer dose reductions for obesity did not influence the composite endpoint of efficacy and safety. Therefore, changing the weight application criteria is considered appropriate from the point of view that it may help to obtain the maximum effect within the tolerable toxicity by patients.
