Asthma, obesity, and eating behaviors according to the Diagnostic and Statistical Manual of Mental Disorders IV in a large population-based sample of adolescents
ABSTRACT Obesity is related to asthma, but factors influencing this relation have not been clearly defined.
This study was designed to assess the role of eating behaviors and weight concerns in the association between obesity and asthma.
A population-based sample of 11,710 adolescents, recruited from 186 secondary schools of 8 educational districts in France, completed a self-administered standardized questionnaire including DSM IV (Diagnostic and Statistical Manual of Mental Disorders) questions on eating disorders.
Obesity (body mass index >/=95th percentile according to age and sex) was associated with asthma in girls (odds ratio: 1.48; 95% CI: 1.05, 2.08) but not in boys (odds ratio: 1.07; 95% CI: 0.75, 1.54). Both obese and asthmatic adolescents were more likely to have abnormal eating behaviors and weight concerns (P < 0.05). In an adjusted polytomous logistic model with 4 categories based on the presence and/or the absence of asthma and obesity as the dependent variable, the odds ratio for weight concerns increased from a minimum value for asthmatic nonobese adolescents (odds ratio: <1.5; P < 0.03) to a maximum value for asthmatic obese adolescents (odds ratio: >6.3; P < 0.001) with nonasthmatic, nonobese adolescents as the reference group. Similar patterns were observed for overweight.
Our data suggest that, besides well-known factors such as genetic background, direct mechanical effects, and reduced physical activity, abnormal eating behaviors and weight concerns might intervene in the relation between obesity and asthma. Psychosocial dimension has to be considered to disentangle the complex relation between obesity and asthma in adolescence in view of prevention.

ABSTRACT: Despite well-documented evidence that physical activity is beneficial to children, average fitness levels of US children have declined. Lack of physical activity has been associated with childhood obesity. We evaluated the effects of a physical activity program in the elementary school classroom on health outcomes. Three schools in the Independence School District in Independence, Missouri, were assigned to receive the ABC (Activity Bursts in the Classroom) for Fitness program, and 2 comparable schools served as controls. The program, led by classroom teachers, provides multiple, brief, structured physical activity breaks throughout the day. Baseline data for the study were collected in September 2007, and follow-up data were collected in April 2008. Physical fitness measures of upper-body strength, abdominal strength, and trunk extensor improved (P <.001). Medication use for asthma (P = .03), attention-deficit hyperactivity disorder (P = .07), or either medication combined (P = .005) decreased. The effects of the program on daily physical activity, fitness, and measures of health are beneficial.Preventing chronic disease 07/2010; 7(4):A82. · 1.96 Impact Factor

ABSTRACT: The purpose of this study was to investigate body weight satisfaction, eating attitudes and dietary intake related to eating disorders of female junior high school students in Taiwan. In a cross-sectional survey, 835 female junior high school students participated in this study. The questionnaire items included respondents' demographic information as well as weight and body image concerns. Developmental and attitudinal scales such as the body shape-related teasing scale, Pubertal Development Scale, Eating Attitudes Test-26 (EAT-26) and 24-hour dietary recall were also used to collect data. Data were analyzed using a Student's t test, chi-square test and logistic regression. Disturbed eating attitudes and behaviors were found in 10.4 % of participants (measured by EAT-26?20). The multivariate logistic regressions showed that disturbed eating attitudes and behaviors were associated with weight/shape-related teasing experiences and dissatisfaction with body weight. The reported intakes of energy, protein, fat, carbohydrate, cholesterol, zinc and vitamins B-6, B-12, were significantly lower in participants with disturbed eating patterns than in participants without disturbed eating. Conversely, participants with disturbed eating patterns had higher dietary and crude fiber intake than participates without disturbed eating. Disturbed eating behaviors exist among female adolescents in Taiwan, and these behaviors jeopardize their necessary dietary intake requirements. More research using the EAT-26 as a measure to predict the quality and quantity of food intake among female adolescents warrants further study.Asia Pacific Journal of Clinical Nutrition 01/2011; 20(2):196-205. · 1.36 Impact Factor

ABSTRACT: Various factors have been reported to influence lipid metabolism and cause metabolic syndrome. However, the influence of allergy on the liver that plays important role of lipid metabolism has not been clarified. The aim of this study was to examine the influence of allergy on lipid metabolism of liver. A model of atopic dermatitis was developed in the NC/Nga mouse using picryl chloride to induce allergy. Lipid metabolism parameters were measured and the mechanism of changes in these parameters was examined using DNA microarray analysis and quantitative reverse transcriptase PCR. Triacylglycerol accumulation was promoted in the liver in the mouse atopic dermatitis model despite reductions in food intake, body weight gain, and serum glucose. As this mechanism, it was thought that atopic dermatitis caused the suppression of fatty acid β-oxidation. These results suggest that atopic dermatitis causes lipid accumulation in the liver.Journal of Clinical Biochemistry and Nutrition 03/2012; 50(2):152-7. DOI:10.3164/jcbn.11-29 · 2.29 Impact Factor
