Authors: Dohm Faith‐Anne , Cachelin Fary M. , Striegel‐Moore Ruth H. 
Published: April 2008

AbstractObjective: Two studies explored in nonclinical samples variables that may influence meal size assessments.Research Methods and Procedures: In Study 1, the contribution of dietary restraint, weight, depressive symptoms, and gender to ratings on the Food Amount Rating Scale was examined in 153 white women and 121 white men; in Study 2, the contribution of dietary restraint, weight, ethnicity, and ethnic group identification to Food Amount Rating Scale ratings was examined in 67 Asian, 81 Hispanic, and 107 white women.Results: Study 1 indicated that food amounts were rated as larger when rated by male rather than female raters (male rater, mean = 62.37, SD = 1.14; female rater, mean = 59.28, SD = 0.89), for female rather than male targets (male target, mean = 56.16, SD = 0.97; female target, mean = 64.87, SD = 1.02), and by restrained rather than unrestrained eaters (restrained, mean = 63.14, SD = 1.11; unrestrained, mean = 58.69, SD = 0.91). Study 2 indicated that food amounts were rated as larger when rated by restrained eaters (restrained, mean = 67.53, SD = 1.21; unrestrained, mean = 64.99, SD = 1.09), Hispanic women (Asian, mean = 64.59, SD = 1.61; Hispanic, mean = 68.71, SD = 1.30; white, mean = 65.41, SD = 1.34), and underweight women (underweight, mean = 70.38, SD = 1.68; normal weight, mean = 64.52, SD = 0.93; overweight: mean = 64.23, SD = 1.64).Discussion: Food amount judgments may be influenced by personal characteristics. Future research should examine whether variation in food amount judgments is related to dieting behavior, disordered eating, or obesity.

Authors: Elfhag Kristina , Linné Yvonne 
Published: April 2008

AbstractObjective: To study the association of eating pathology between mothers and their adolescent offspring in a population sample.Research Methods and Procedures: The participants were 481 women (mean age, 47 ± SD 5 years; BMI, 25 ± 4 kg/m2) and their 481 adolescent children 16 to 17 years old (BMI, 21 ± 3 kg/m2) of the Stockholm Weight Development Study. Assessment methods were the Three‐Factor Eating Questionnaire Revised 18 and the Eating Disorder Inventory 2.Results: A higher body weight was most related to cognitive restraint for adolescents and to emotional eating for adult women. A mother‐daughter link could be identified for eating pathology, with the strongest link found for emotional eating. No mother‐son link could be identified. Age subgroup analyses revealed a stronger mother‐daughter link for body attitudes in younger mothers and for cognitive restraint in older mothers.Discussion: Gender differences revealed that eating pathology was shared by mothers and daughters but not by mothers and sons. A psychological strategy such as eating as a response to negative emotions was most interrelated between mothers and daughters. Younger mothers shared more attitudes toward the body with their daughters, whereas older mothers shared more restrictive eating behaviors with their daughters. The mother‐daughter links found may be due to gender‐specific genetic and psychological family transmission and gender‐specific environmental influences. The sons’ eating behaviors seem to be more independent and would be formed by other factors than for the girls.

Published: April 2008

AbstractObjective:This study examined differences in (1) psychosocial correlates of physical activity and in (2) physical activity within different contexts and sedentary behaviors between normal weight and overweight adolescents. It further explored whether the prediction of physical activity by the psychosocial correlates is different in normal weight and overweight adolescents.Research Methods and Procedure: A community sample of 6078 11 to 19 year olds from 38 secondary schools, which were randomly selected throughout the country, completed a validated computerized questionnaire about physical activity, sedentary behaviors, and psychosocial correlates. Differences in mean scores on the psychosocial correlates and on the self‐rated physical activity were analyzed between the normal weight (n = 5563) and the overweight (n = 515, 8.5%) group.Results: This study showed that overweight adolescents do less intense physical activities (p < 0.001) and have less favorable psychosocial correlates related to physical activity (p < 0.001) than their normal weight counterparts. However, the strength of the associations between psychosocial variables and total physical activity were comparable in overweight and normal weight adolescents. More support from family and friends, more fun in physical activity, higher self‐efficacy, the perception of more competition benefits, and the perception of less lack of interest were all associated with higher total levels of physical activity. The results suggest that no specific tailoring on psychosocial correlates of physical activity is necessary for overweight adolescents compared with normal weight ones.Discussion: Both overweight and normal weight adolescents can be approached by interventions focusing on the same psychosocial variables to increase physical activity.

Published: April 2008

AbstractObjective: To determine whether the U.S. Centers for Disease Control and Prevention (CDC; CDC Reference) or International Obesity Task Force (IOTF; IOTF Reference) BMI cut‐off points for classifying adiposity status in children are more effective at predicting future health risk.Research Methods and Procedures: The sample (N = 1709) included 4‐ to 15‐year‐old (at baseline) boys and girls from the Bogalusa Heart Study. Overweight and obesity status were determined using both the CDC Reference and IOTF Reference BMI cut‐off points at baseline. The ability of childhood overweight and obesity, determined from the two BMI classification systems, to predict obesity and metabolic disorders in young adulthood (after a 13‐ to 24‐year follow‐up) was then compared.Results: Independently of the classification system employed to determine adiposity based on childhood BMI, the odds of being obese and having all of the metabolic disorders in young adulthood were significantly (p < 0.05) higher in the overweight and obese groups by comparison with the nonoverweight groups. Childhood overweight and obesity, determined by both the CDC Reference and IOTF Reference, had a low sensitivity and a high specificity for predicting obesity and metabolic disorders in young adulthood. Overweight and obesity as determined by the CDC Reference were slightly more sensitive and slightly less specific than the corresponding values based on the IOTF Reference.Discussion: Overweight and obesity during childhood, as determined by both the CDC and IOTF BMI cut‐off points, are strong predictors of obesity and coronary heart disease risk factors in young adulthood. The differences in the predictive capacity of the CDC Reference and IOTF Reference are, however, minimal.

AbstractObjective: Adiponectin has been proposed to be related to endothelial function. We have examined the relationship between the increase in adiponectin levels that is associated with troglitazone treatment and endothelium‐dependent vasodilation in type 2 diabetic patients.Research Methods and Procedures: Seventy‐two patients participated in this randomized, placebo‐controlled, double‐blinded study. High‐resolution ultrasound images were used to measure the flow‐mediated dilation (endothelium‐dependent) and nitroglycerin‐induced dilation (endothelium‐independent) of the brachial artery. Laser Doppler perfusion imaging was employed to measure the vascular reactivity in the forearm skin.Results: Troglitazone treatment resulted in an average 75% increase in the adiponectin levels, but no changes were observed in the endothelium‐dependent vasodilation, any other measurement of vascular reactivity, or any other markers of endothelial activation. Also, no changes were observed in the expression of the receptor for advanced glycation end‐products in skin biopsies taken from the forearm. Significant correlations were observed during troglitazone treatment between the changes in the adiponectin levels and the changes in fasting plasma glucose (r = −0.29, p < 0.05), hemoglobin A1c (r = −0.30, p < 0.05), total cholesterol (r = 0.25, p < 0.05), and low‐density lipoprotein‐cholesterol (r = 0.34, p < 0.01).Discussion: The increase in adiponectin levels after troglitazone treatment is not associated with an improvement in the endothelium‐dependent vasodilation, indicating that adiponectin is not a major determinant of endothelial function. In addition, receptor for advanced glycation end‐products expression in the skin microcirculation is not affected by troglitazone treatment.

Published: April 2008

AbstractObjectives: Non‐alcoholic fatty liver disease (NAFLD) is the most common cause of liver disease in the United States and is prevalent in morbidly obese patients. While weight loss and treatment of risk factors are recommended, the reported effects of bariatric surgery on NAFLD are mixed.Research Methods and Procedures: We examined liver histology at the time of Roux‐en‐Y gastric bypass surgery and at elective incisional hernia repair after weight loss for 16 patients at one center. Slides were read by one pathologist, blinded to clinical data, using the Brunt criteria. Clinical and laboratory data were extracted from chart review. Alcohol use was ascertained by two interviews.Results: At baseline, the mean age was 44 years, 50% were women, 88% were white, and the mean BMI was 51 kg/m2. None had significant alcohol use. On initial biopsy, all patients showed steatosis, 94% had inflammation, 88% had ballooning degeneration, 88% had perisinusoidal fibrosis, and 81% had portal fibrosis. The mean time between the two biopsies was 305 ± 131 (SD) days. The mean weight loss was 118 ± 29 lb. Steatosis improved in 15 of 16 patients, with resolution in 13. Twelve of 15 patients with inflammation at baseline showed improvement, and 12 of 14 showed less ballooning. Six of 14 patients with perisinusoidal fibrosis and 6 of 13 with portal fibrosis showed improvement. No patient had worsening of steatosis, inflammation, ballooning, or fibrosis.Discussion: Our study shows improvement in all of the histological features of NAFLD after Roux‐en‐Y gastric bypass surgery—induced weight loss, despite significant histopathology at baseline and substantial weight loss.

Published: April 2008

AbstractObjective: To compare the thermic response to a meal between men and women of varied body composition and to determine whether adrenergic amines extracted from citrus aurantium (CA) induce an increase in metabolic rate and enhance the thermic response to the meal.Research Methods and Procedures: In 30 healthy weight‐stable subjects (17 women, 13 men; BMI: 20 to 42 kg/m2), body composition was determined by bioimpedance analysis followed by resting energy expenditure for 20 minutes, and the thermic effect of food (TEF) of a 1.7‐MJ, 30‐gram protein meal was determined intermittently for 300 minutes by indirect calorimetry. In a subset of 22 subjects, the TEFs of CA alone and when added to the same 1.7‐MJ meal were determined. Blood pressure and pulse before and throughout the studies and catecholamine excretion were determined.Results: TEF was significantly lower in women than men (152 ± 7 vs. 190 ± 12 kJ and 8.8 ± 0.4% vs. 11.0 ± 0.7% of meal), independently of age and magnitude of adiposity. The thermic response to CA alone was higher in men, but, when added to the meal, CA increased TEF only in women and to values no longer different from men. CA had no effect on blood pressure and pulse rate but increased epinephrine excretion by 2.4‐fold.Discussion: A 20% lower TEF in women suggests a diminished sympathetic nervous system response to meals, because with CA, TEF increased by 29% only in women. However, this acute response may not translate into a chronic effect or a clinically significant weight loss over time.
Stigmatized Students: Age, Sex, and Ethnicity Effects in the Stigmatization of Obesity

Published: April 2008

AbstractObjective: To assess the stigmatization of obesity relative to the stigmatization of various disabilities among young men and women. Attitudes across ethnic groups were compared. In addition, these findings were compared with data showing severe stigmatization of obesity among children.Research Methods and Procedures: Participants included 356 university students (56% women; mean age, 20.6 years; mean BMI, 23.3 kg/m2; range, 14.4 to 45.0 kg/m2) who ranked six drawings of same‐sex peers in order of how well they liked each person. The drawings showed adults with obesity, various disabilities, or no disability. These rankings were compared with those obtained through a similar procedure with 458 fifth‐ and sixth‐grade children.Results: Obesity was highly stigmatized relative to physical disabilities. African‐American women liked obese peers more than did African‐American men, white men, or white women [F (1, 216) = 4.02, p < 0.05]. Overweight and obese participants were no less stigmatizing of obesity than normal weight participants. Adults were more accepting than children of their obese peers [t (761) = 9.16, p < 0.001].Discussion: Although the stigmatization of obesity was high among participants overall, African‐American women seemed to have more positive attitudes toward obesity than did white women, white men, or African‐American men. Participants’ weight did not affect their stigmatization of obesity: obese and overweight adults were as highly stigmatizing of obesity as non‐overweight adults. Such internalized stigmatization could help to explain the low self‐esteem and poor body image among obese young adults. However, adults seemed to have more positive attitudes about obesity than children. An understanding of the factors that limit the stigma of obesity among African‐American women could help efforts to reduce stigma.

Published: April 2008

AbstractObjectives: The metabolic syndrome has become a significant health problem worldwide. In this study, we investigated the relationship between the metabolic syndrome, bright liver (BL) by ultrasonography (US), and plasma alanine aminotransferase (ALT) levels among apparently healthy adults.Research Methods and Procedures: A total of 15, 430 nonalcoholic healthy adults without hepatitis B or C were recruited from four nationwide MJ Health Screening Centers in Taiwan in 2000. Metabolic syndrome was defined using the National Cholesterol Education Panel (NCEP) metabolic syndrome criteria or modified NCEP criteria. Based on liver US, subjects were classified into either having BL or not. The relationship between the metabolic syndrome, BL, and ALT levels was examined using multivariate logistic regression analysis.Results: The crude OR of the metabolic syndrome was 13.92 (12.19 using modified NCEP criteria), and the age‐BMI‐sex—adjusted OR was 3.77 (3.71 using modified NCEP criteria) in subjects with BL vs. subjects without BL, respectively. The ORs of the metabolic syndrome were significantly higher in subjects with elevated ALT levels than in those with normal ALT levels. After adjustment for age, sex, and BMI, BL and elevated ALT level were independently associated with increased risk of the metabolic syndrome.Discussion: Presence of BL and elevated plasma ALT level was independently associated with increased risk of the metabolic syndrome in adults. These factors contribute to a list of well‐known risk factors, including obesity, aging, and male sex, and thus can be applied as an additional evaluation for the metabolic syndrome in a clinical setting.

Published: April 2008

AbstractObjectives: We examined the relationship between comprehensive fitness tests and overweight using a school surveillance system in a racially diverse city in the United States.Research Methods and Procedures: Trained physical education teachers measured weight, height, and fitness annually from 2001 to 2003. We compiled data for a cross‐sectional analysis (11, 845 measurements on 6297 students, 5 to14 years of age) and a 1‐year prospective analysis (4215 measurements on 2927 students not overweight at baseline, 5 to 13 years of age). Overweight was defined as a BMI ≥95th percentile (Centers for Disease Control and Prevention 2000 growth charts), and underfit was defined as failing at least one of five fitness tests: endurance run, abdominal strength, flexibility, upper body strength, and agility (Amateur Athletic Union and Fitnessgram). Associations between fitness and overweight were examined using multivariate logistic regression models, adjusting for sociodemographic status and repeated measurements over time.Results: The mean number of fitness tests passed was lower among students with a BMI above the 80th percentile. Overweight incidence over 1 year was 7% and 2% for underfit and fit girls, respectively (odds ratio, 3.3; 95% confidence interval, 2.0 to 5.6). Not passing either the endurance run or upper body strength test was associated with overweight incidence in both boys and girls. After adjusting for baseline BMI, the endurance run remained a significant predictor of incident overweight among girls (odds ratio, 2.0; 95% confidence interval, 1.1 to 3.5).Discussion: Findings support a cross‐sectional inverse relationship between physical fitness and overweight among school‐aged children. The direction of causation between fitness and overweight is not clearly established and merits further study.
Simplified Resting Metabolic Rate—Predicting Formulas for Normal‐Sized and Obese Individuals
Authors: Livingston Edward H. , Kohlstadt Ingrid 
Published: April 2008

AbstractObjective: Resting metabolic rate (RMR) is known to be proportional to body weight and to follow allometric scaling principles. We hypothesized that RMR can be predicted from an allometric formula with weight alone as an independent variable.Research Methods and Procedures: An allometric, power‐law scaling model was fit to RMR measurements obtained from a cohort of patients being treated for weight loss. This, as well as many of the commonly used RMR‐predicting formulas, was tested for RMR prediction ability against a large publicly available RMR database. Bland‐Altman analysis was used to determine the efficacy of the various RMR‐predicting formulas in obese and non‐obese subjects.Results: Power law modeling of the RMR—body weight relationship yielded the following RMR‐predicting equations: RMRWomen= 248 × Weight0.4356− (5.09 × Age) and RMRMen= 293 × Weight0.4330− (5.92 × Age). Partial correlation analysis revealed that age significantly contributed to RMR variance and was necessary to include in RMR prediction formulas. The James, allometric, and Harris‐Benedict formulas all yielded reasonable RMR predictions for normal sized and obese subjects.Discussion: A simple power formula relating RMR to body weight can be a reasonable RMR estimator for normal‐sized and obese individuals but still requires an age term and separate formulas for men and women for the best possible RMR estimates. The apparent performance of RMR‐predicting formulas is highly dependent on the methodology employed to compare the various formulas.
Children at High Risk for Overweight: A Classification and Regression Trees Analysis Approach
Authors: Toschke André Michael , Beyerlein Andreas , Von Kries Rüdiger 
Published: April 2008

AbstractObjective: Early identification of children at high risk for childhood overweight is a major challenge in fighting the obesity epidemic. We tried to identify the most powerful set of combined predictors for childhood overweight at school entry.Research Methods and Procedures: A classification and regression trees analysis on risk factors for childhood overweight in 4289 children 5 to 6 years of age participating in the obligatory school entry health examination 2001/2002 in Bavaria, Germany, was performed. Parental questionnaires asked for children's weight at birth and 2 years, breastfeeding history, maternal smoking in pregnancy, parental education, parental overweight/obesity, nationality, and number of older siblings. Overweight was defined according to sex‐ and age‐specific BMI cut‐points proposed by the International Obesity Task Force.Results: Prevalence of overweight was 11% among the entire study population. Although high early weight gain >10, 000 grams was found in about one‐half of the overweight children, its positive predictive value reached only 25%, indicating that one of four children with a high early weight gain is overweight at school entry. The best reliable set of predictors included high early weight gain and obese parents and accounted for a likelihood ratio of 3.6, with a corresponding positive predictive value of 40%, and was found in 4% of all children.Discussion: A combination of predictors available at 2 years of age could improve predictability of overweight at school entry. However, corresponding low positive predictive values indicate a precision of the prediction that might be insufficient for targeting intervention programs for identified high‐risk children.
