Preoccupation with Body Weight and Under-Reporting of Energy Intake in Female Japanese Nutrition Students. Nutrients 2020; 12:nu12030830. [PMID: 32244995 PMCID: PMC7146226 DOI: 10.3390/nu12030830] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2020] [Revised: 03/18/2020] [Accepted: 03/18/2020] [Indexed: 02/03/2023] Open
Abstract
The present study aimed to examine associations between body image and under-reporting in female Japanese university students enrolled in a nutrition degree program. A total of 100 participants (aged 18-29 years) completed (1) a self-administered questionnaire including the Ben-Tovim Walker Body Attitudes Questionnaire (BAQ), (2) a dietary assessment using a brief-type self-administered diet history questionnaire (BDHQ), (3) a physical activity assessment using Bouchard's Physical Activity Record (BAR) and a tri-axial accelerometer, (4) detailed anthropometry, and (5) body composition assessment. Based on the energy intake to basal metabolic rate ratio (EI:BMR) and using a cut-off point of 1.35, 67% of participants were considered under-reporters (URs). While there was no between-group difference in BMI, URs had significantly (p < 0.05) greater percentage body fat (%BF) and trunk fat (%TF) compared with non-URs. Regression analyses indicated accuracy of body perception and a discrepancy between current and ideal weight were associated with EI:BMR, whereas the salience subscale of the BAQ was associated with reported EI. The study raises concerns regarding the validity of EI reported from young Japanese females as they are known to have a strong preoccupation with thinness, even with an acceptable BMI and health and nutritional knowledge.

Abstract
The EHU12/24 (code of a survey from the University of the Basque Country/Euskal Herriko Unibertsitatea, UPV/EHU) study was designed to investigate the risk factors of overweight/obesity-related lifestyles, particularly those associated with diet, their psychosocial influences and the interactions among these factors. This observational cohort study was carried out according to a standardised protocol and involved a representative sample of the UPV/EHU student population. Anthropometric measurements, direct behavioural determinants, such as physical activity and diet, and indirect determinants, such as social/psychological factors, are considered. In this paper, we present the survey design, instruments, measurements and related quality management. We describe the study sample in terms of its socio-economic and demographic factors and knowledge area and summarise the methodology used to collect the data and obtain the anthropometric measurements. The participants were 603 students (59·5 % female) aged 18-28 years. The crude participation proportion was 53·5 %. Regarding the knowledge area, the lowest response proportions were obtained from the Health Sciences (38·6 %) compared with the Non-Health Sciences (48·3 %) (P = 0·003). The mean age was 20·9 years, and 83·1 % of the sample were from Basque Country. Regarding the socio-economic characteristics, there were significant differences by sex and knowledge area in most studied variables. Moreover, the Health Sciences students were more likely younger, from outside Basque Country, to have parents with university degrees and to have a higher social status. In conclusion, the EHU12/24 cohort provides valuable data for analysing the complexity and multidimensionality of obesity in university students.

Abstract
This cross-sectional study investigated location of body fat, with specific focus on abdominal fat, among normal weight and overweight women who accurately or inaccurately perceived their weight status. Young, adult women (N = 120; M age = 19.5 yr., SD = 1.2) were asked to classify their weight status using the Self-Classified Weight subscale from the Multidimensional Body-Self Relations Questionnaire. Actual weight status was operationalized via dual-energy x-ray absorptiometry. Overweight women who thought they were normal weight had an average of 19 pounds more fat than normal weight women with 1.5 pounds of excess abdominal fat. Interventions to raise awareness among overweight women unaware of their fat level are warranted. However, these interventions should balance consideration of potential detriments to body image among these women.

Abstract
BACKGROUND Elevated body mass index (BMI), higher waist-to-hip ratio, and body dissatisfaction have been investigated as risk factors for the development of bulimic symptoms. Central fat deposition may be particularly relevant to eating disorders. To our knowledge, the longitudinal relations between fat distribution, body dissatisfaction, and loss-of-control (LOC) eating development and maintenance have not been studied. OBJECTIVE We examined body fat distribution, independent of BMI and depressive symptoms, as a unique correlate and predictor of body dissatisfaction and LOC eating cross-sectionally and over a 2-y follow-up. DESIGN Body composition was measured by using dual-energy X-ray absorptiometry in 294 adult women at risk of weight gain at baseline, 6 mo, and 24 mo. We assessed LOC eating, body dissatisfaction, and depressive symptoms at baseline, 6 wk, 6 mo, 12 mo, and 24 mo by using the Eating Disorder Diagnostic Interview, the Multidimensional Body-Self Relations Questionnaire-Appearance Scales Body Areas Satisfaction subscale, and the Center for Epidemiologic Studies-Depression Scale, respectively. RESULTS Independent of BMI, baseline total percentage body fat, percentage trunk fat, and percentage abdominal fat were related to greater body dissatisfaction. Total percentage body fat and trunk fat tended to be associated with greater body dissatisfaction at all subsequent time points. Women with a greater percentage trunk fat, specifically abdominal fat, were at highest risk of developing LOC eating. In the full sample, women with higher baseline percentage trunk and abdominal fat showed increases in LOC eating episode frequency over time, whereas LOC eating frequency remained stable among women with smaller percentages of fat in trunk and abdominal regions. CONCLUSION These findings lend further support to the premise that increased central body fat deposition is associated with body image dissatisfaction and suggest that it may represent a risk and maintenance factor for LOC eating. This trial was registered at clinicaltrials.gov as NCT00456131.

Abstract
Collegiate athletes often use nutritional programs and supplements to elicit body composition changes in muscle or fat. It is unknown if athletes can accurately perceive their fluctuations in body composition, yet their understanding may help them make more accurate interpretations regarding the success of potential nutrition or exercise regimens. The purpose of this study was to investigate if collegiate hockey players could accurately perceive a change in body composition during a 3-month period within their regular season, in which no predetermined nutritional or exercise program was provided. Twenty-four male Canadian collegiate hockey players completed preseason and midseason body composition assessments using dual-energy X-ray absorptiometry. Immediately before the midseason scan, players attempted to accurately match their perceived fluctuation in composition, with predetermined categorical ranges of relative body composition and strength. Two-thirds of players and one-half of players accurately perceived changes in arm-lean and arm-fat tissue, respectively. Approximately two-thirds of players did not accurately perceive gains or losses of lean or fat tissue within their leg and overall body. Although some athletes partially detected changes in the lean and fat tissue of particular regions, the vast majority of players cannot detect the type, or amount of tissue gained and lost across the overall body. Body composition assessments, rather than an athlete's perceptions, should be used to help interpret the success of a sport nutrition or exercise program. Athletes should be aware that physiologic adaptations might take place unnoticed, which could affect the acceptance and adherence of nutrition or exercise interventions.

Abstract
BACKGROUND/OBJECTIVES To identify the prevalence and factors associated with body dissatisfaction. SUBJECTS/METHODS Birth cohort study investigating 4100 subjects (2187 men and 1913 women) aged between 22 and 23 years who answered questionnaires, including the body satisfaction Stunkard Scale were included in the study; they were weighed and measured. Multinomial logistic regression was used in the crude and adjusted analyses. RESULTS The prevalence of body dissatisfaction was 64% (95% CI, 62.7-65.6); 42% (95% CI, 40.6-43.6) of the subjects reported feeling larger than the desired body size, and 22% (95% CI, 20.7-23.3) reported feeling smaller than desired. Underweight subjects, subjects with less schooling, poor and sedentary male subjects with low psychological well-being and female subjects who were already mothers were more likely to express body dissatisfaction, perceiving their body as smaller than the desirable body size. The prevalence of body dissatisfaction was also high among overweight subjects, subjects with a high socioeconomic status and married female subjects, who perceived their body size as too large. Minor psychiatric disorders were associated with body dissatisfaction in all subjects, regardless of perceiving themselves as larger or smaller than the desired body size. Most women perceived themselves as larger, but similar proportions of men perceived themselves as too small or too large. CONCLUSIONS Body dissatisfaction was observed among men and women with normal weight, but it was more evident in the obese individuals. Regardless of the nutritional status, both men and women should be appropriately counseled because body size perception can lead to unhealthy behaviors in relation to diet and physical activity.

Abstract
INTRODUÇÃO: O objetivo do estudo foi verificar a associação entre insatisfação com a imagem corporal e dois indicadores de estado nutricional em universitários brasileiros, assim como identificar o melhor preditor de insatisfação com a imagem corporal em universitários brasileiros. MÉTODOS: Trata-se de um estudo transversal, realizado com 256 universitários (128 homens). Foram coletados dados demográficos (sexo e idade), antropométricos (massa corporal, estatura e espessura de dobras cutâneas) e de imagem corporal (silhueta atual e silhueta ideal). O índice de massa corporal (< 18,5 ou ≥ 25,0 kg/m² = inadequado) e o somatório de espessura de cinco dobras cutâneas (≤ 30 ou ≥ 62 e ≤ 43 ou ≥ 76 mm = inadequado, para homens e mulheres, respectivamente) foram derivados subseqüentemente. A análise incluiu estatística descritiva, teste de proporção, qui-quadrado e regressão logística. RESULTADOS: A média de idade dos indivíduos foi de 23,1 anos (desvio padrão = 5,3), e a freqüência de insatisfeitos com a imagem corporal foi de 78,8%. A insatisfação com a imagem corporal não se associou ao sexo e ao índice de massa corporal. A análise multivariada demonstrou que a odds ratio associada ao somatório de espessura de cinco dobras cutâneas inadequado foi de 2,56. CONCLUSÃO: O índice de massa corporal não foi determinante de insatisfação com a imagem corporal, enquanto o somatório de espessura de cinco dobras cutâneas mostrou-se um preditor significativo desse distúrbio, independentemente do sexo.

Abstract
The body composition of 139 Japanese females and 84 Japanese males (aged 18-30 years) was measured using anthropometry to assess gender differences in body perceptions in relation to their measured values. Participants were asked to rate perceptions of their own "heaviness" and "fatness" and these were compared to their BMI and percent body fat (%BF). Japanese females showed a significantly greater desire to lose body weight (-4.20+/-0.6 kg) compared to males (0.27+/-1.4 kg). Females also showed poor understanding of their "heaviness" and "fatness" in relation to actual body composition compared to males. The results confirmed distinct gender differences in body perception in relation to actual body composition and attitudes to weight management. Further promotion of "healthy" body image is recommended for the Japanese population.

Abstract
OBJECTIVE To examine the effect of age on the relationship between fat-free mass (FFM) and fat mass (FM), and fat-free mass index (FFMI) and fat mass index (FMI) by applying body composition chart analysis on pre- and postadolescent Japanese subjects. SUBJECTS AND METHOD A sample of 516 children (244 boys and 272 girls) ranging in age from 11 to 17 y and 840 adults (288 male and 552 female subjects) ranging in age from 18 to 59 y were studied to determine a body composition by an underwater weighing method. FMI and FM were put on an x- and y-axis in body composition chart 1, and FFMI (FFM/ height(2)) and FMI (FM/height(2)) were taken on an x- and y-axis in body composition chart 2. RESULTS In body composition chart 1, the plots for male subjects stayed flat from 11 to 14 y and after that a steady growth of FFM concurring with the FM growth was observed. During the adult stage, steady increments of FM and gradual decreases of FFM were observed. In body composition chart 2, steady increases of FFMI and gradual decreases of FMI were indicated in the male preadolescent period. In the adult stage, FFMI decreased year by year, although the FMI continued to increase. In female subjects, a conspicuous increase of FMI was observed throughout all periods of the present subjects. After middle age, the decline of FFMI was characteristically demonstrated in the chart. CONCLUSION The relationships between FFM and FM are characteristically delineated on the body composition charts demonstrating clear gender differences. The change of body mass index was not reflecting the change of adiposity level in male subjects, although it was occurring along with the changes of the adiposity level in female subjects.
