A comparison of energy intake and food selection during laboratory binge eating episodes in obese women with and without a binge eating disorder diagnosis

OBJECTIVE: The purpose of the study was to compare energy intake and food selection of laboratory binge eating episodes in obese women with and without binge eating disorder (BED). METHOD: Twenty women, 12 meeting BED criteria, and 8 BMI and age matched obese controls, engaged in a laboratory binge eating episode. RESULTS: BED participants consumed significantly more total food in kilocalories than the non-BED obese group and more kilocalories of fat. However, there were no differences between the groups in the proportion of calories from any macronutrient. There was a nonsignificant trend for the BED group to consume more total grams of food. During the binge, the BED group consumed more dairy products. CONCLUSION: Results of the study confirmed that women with BED consumed significantly more total food in kilocalories than the non-BED obese women when they were allowed to have a binge eating episode in a laboratory setting.     

Physical activity, cardiorespiratory fitness and body mass index as predictors of substantial weight gain and obesity: the Canadian physical activity longitudinal study

BACKGROUND: Obesity is a growing health issue in Canada and the identification of the determinants of obesity is important for the development of prevention strategies. The purpose of this investigation was to determine the relationships between physical activity, cardiorespiratory fitness, body mass index (BMI), and the development of future obesity. METHODS: The sample included 459 adults (18+ y; 223 men, 236 women) from the Canadian Physical Activity Longitudinal Study (PALS; 2002-04). Data on physical activity, smoking, alcohol consumption, BMI, and cardiorespiratory fitness (VO2max) were collected in 1981 and 1988. The mean BMI, physical activity, and VO2max were calculated across the 1981 and 1988 measures. Self-reported height and weight were collected in the 2002-04 survey, and participants were classified as overweight (BMI 25 to 29.9 kg/m2) or obese (BMI 230 kg/m2). Logistic regression was used to predict overweight, obesity or substantial weight gain (10 kg or more) in 2002-04, controlling for age, sex, smoking and alcohol use. RESULTS: Higher VO2max in 1981-88 was associated with lower odds of obesity in 2002-04 (OR = 0.87; 95% Cl: 0.76-0.99, p < 0.05), and higher BMI in 1981-88 was associated with higher odds of obesity in 2002-04 (1.84; 1.52-2.20, p < 0.0001). In women, higher VO2max (0.82; 0.72-0.93) resulted in lower odds of a 10 kg weight gain. CONCLUSIONS: The results indicate that cardiorespiratory fitness and previous BMI are important predictors of future weight gain and obesity, and should be incorporated in strategies to identify individuals at increased risk of obesity.     

Physical Activity,Cardiorespiratory Fitness,and their Relationship to Cardiovascular Risk Factors in African Americans and Non-African Americans With Above-Optimal Blood Pressure

This report describes cross-sectional associations among physical activity, cardiorespiratory fitness, dietary habits, and cardiovascular disease (CVD) risk factors in a large sample (n=810) of African Americans (n=279) and non-African Americans (n=531) with above-optimal blood pressure. Participants in PREMIER, a clinical trial for blood pressure control through lifestyle approaches, underwent baseline assessments to determine physical activity level, cardiorespiratory fitness category, dietary intake, and CVD risk factors. Mean levels of body mass index (BMI), total cholesterol, LDL cholesterol, HDL cholesterol, daily percent calories from fat and saturated fat, daily servings of fruits and vegetables, and daily fiber intake were examined across three physical activity levels and two fitness categories. Hypertension status was also assessed. Data were stratified by sex and ethnicity. For all participants, those in the low fitness category had higher BMI levels. Total cholesterol was lower in African American women in the high fitness category. Mean values of more than five daily servings of fruits and vegetables were reported by non-African American women and African American men in the high activity category. Higher intake of dietary fiber was found for non-African American women at the high activity level, with a similar trend observed for African American women. Future work examining these associations prospectively should include sufficient minority representation to enhance generalizability to all population groups and determine the beneficial effects from increased physical activity and improved cardiorespiratory fitness.Deborah Rohm Young, PhD, is Associate Professor of Kinesiology at University of Maryland, College Park, MD; Mikel Aickin, PhD, is a Senior Investigator at Kaiser Permanente Center for Health Research, Portland, OR; Philip Brantley, PhD, is Professor and Director of the Division of Educational Programs and Chief of Behavioral Medicine at Pennington Biomedical Research Center/Louisiana State University, Baton Rouge, LA; Patricia J.

Comparisons of attitudes and practices between obese and normal weight women in Taiwan

This study was designed to obtain baseline data regarding self-reported body image, attitudes toward overweight people, and dietary behaviors of normal-weight and obese women in Taiwan. Fifty obese women (BMI >= 27) and age-matched normal-weight women participated in this study. Written questionnaires were used for data collection. Simple frequency and t-test were used to analyze data. In general, the majority of normal-weight women perceived themselves as being heavier than their actual body weight. The normal-weight group had more high inaccurate images of their bodies than that of the obese group (72% vs. 24%). Obese and normal-weight women had similar attitudes to overweight people, but some of their attitudes showed significant differences. Obese women would prefer to consume more fried foods and drink sugar-containing foods than would normal-weight women (p < 0.05). Education about accurate perceptions of what is normal weight for women and adopting energy-diluted foods for obese women is needed in the future.     

The comparison in daily intake of nutrients, dietary habits and body composition of female college students by body mass index

The purpose of this study was to investigate differences in the body composition, dietary habits, daily intake of nutrients and clinical blood indices in female college students by body mass index of normal weight, overweight and obese. The subjects of this research were 141 respondents of a survey carried out on students, and subjects were given 60 minutes to answer questionnaires, by recording their own answers. The average heights and weights of subjects by BMI were 162.17 cm, 52.73 kg in normal weight group, 162.35 cm, 62.22 kg in overweight group and 161.72 cm, 69.82 kg in obesity group, respectively. As for the survey daily of meals, starving breakfast and kind of snacks of subjects were significantly different among the groups by BMI. In animal protein food intakes, meat intake was the highest ''every day'' food consumed by subjects, and there was a significant difference in distribution of BMI among subjects. Fruits, and greenish and yellow vegetables intakes were the highest ''every day'' foods indicated by the normal weight group. Consumption of carbonated beverages and juices showed a significant difference among groups by BMI. The average of total-cholesterol was the overweight group was the higher value. There was a significant difference in diastolic blood pressure and systolic blood pressure among the groups by BMI. Average daily calories intake levels were insufficient and the intake ratio of carbohydrates, protein, and fat was the normal weight group 68:17:15, the overweight group 64:18:18 and the obese group 73:14:13. Results of the daily vitamin intake analyses displayed riboflavin, niacin, vitamin C, and folic acid levels lower than the RI levels. Fe intake was the normal weight group 81%, overweight group 76%, obese group 59% of the RI level. Therefore, it is necessary for college students to establish regular meals, good quality snacks and consuming more vitamin and mineral nutritions for optimal health conditions.     

The Relationship of Body Size to Participation and Success in a Fruits and Vegetables Intervention among Low-income Women

We examined participation and dietary change among women participants in a community-based nutrition education program, to determine whether intervention results differed by participant body size. Four dietary indicators (daily servings of fruits and vegetables, total calories, calories from fat, and Healthy Eating Index score) were assessed from 24-h recalls taken before, immediately after, and 4 months after a seven-session nutritional education program, from 156 African-American women age 20–50, in Washington, D.C. public housing. Knowledge, attitudes and practices related to nutritional behavior change were collected at three timepoints as well. Random effect models were used to examine dietary patterns, and compare change by body size and class attendance. Results showed that obese women (BMI ≥ 30) had more psychosocial barriers to dietary change and poorer baseline diets, but stronger program attendance. Post-intervention, both groups consumed approximately 250 fewer calories and 2.5% fewer calories from fat. At follow-up, non-obese women consumed significantly fewer calories; obese women consumed significantly fewer calories from fat, and showed significant improvement in HEI. Given the prevalence of obesity in low resource communities, nutritional interventions should tailor strategies to participant body size and related psychosocial needs.

Knowledge,Attitudes and Provider Advice by Pre-Pregnancy Weight Status: A Qualitative Study of Pregnant Latinas With Excessive Gestational Weight Gain

Latina women are at high risk of excessive gestational weight gain (GWG) during pregnancy; yet little is known about whether factors related to GWG differ by pre-pregnancy body mass index (BMI) within this population. We conducted in-depth interviews with 62 pregnant Latina women with pre-pregnancy BMIs in the healthy, overweight, and obese ranges, gestational age ≥22 weeks, and GWG for gestational age above Institute of Medicine (IOM) guidelines. Compared to healthy weight and obese women, overweight women least often reported viewing weight as important, making efforts to control their GWG, being aware of the role of diet on GWG, and receiving GWG advice from health-care providers. Among those who received GWG advice, overweight women more often recalled a target GWG above IOM guidelines. Obese women more often reported low acceptance of their GWG, concern about GWG, having received GWG advice from providers, difficulty following providers’ dietary advice, and emotional eating as a challenge for controlling GWG. Participants welcomed practical advice to manage GWG. Future interventions to prevent excessive GWG among Latina women should consider differences among women of varying pre-pregnancy BMIs and include multi-level strategies to address psychosocial as well as provider factors.     

Obesity and leisure time physical activity among Canadians

BACKGROUND: The association between physical activity and obesity are age and sex related. METHODS: The analysis was based on data from 81,512 Canadians aged 20 to 64 years who participated in the Canadian Community Health Survey conducted in 2000-01. Information collected included body mass index (BMI:<25.0 kg/m(2) (normal weight); 25.0-29.9 kg/m(2) (overweight); and 30.0+ kg/m(2) (obese)) and energy expenditure (EE) calculated based on the frequency and duration of leisure time physical activity (LTPA) and its value of metabolic energy cost. RESULTS: Obese men and both obese and overweight women had lower EE values compared with those with normal weight. Overweight men 30 to 49 years of age were more active than men with normal weight. Average EE values decreased with age. Overall, 53.2% of men and 57.1% of women were inactive (EE<1.5 kcal/kg/day). In obese men and women, the corresponding prevalences were 59.7% and 71.4%, respectively. The prevalence of physical inactivity increased with increasing BMI in women and there was no "dose-effect" relationship in men. CONCLUSIONS: Obese Canadians are less active, but overweight men tend to be more active than those with normal weight. The variation in the associations across age and sex groups suggests that intervention program development should take age and sex into consideration.     

Cardiorespiratory fitness, weight status and objectively measured sedentary behaviour and physical activity in rural and urban Portuguese adolescents

Relationships among weight status (body mass index [BMI]), cardiorespiratory fitness (CRF) and objective measures of sedentary behaviour and physical activity (PA) were considered in a cross-sectional sample of Portuguese adolescents. The sample included 362 youth aged 13-16 years (165 males, 197 females) from urban and rural regions of the Portuguese midlands. CRF was assessed with the 20-m shuttle-run test. An uniaxial accelerometer was used to obtain five consecutive days of activity behaviours including time being sedentary. Pearson correlations and logistic regression analysis were used to examine relationships among variables. Rural adolescents were less active than their urban peers over the weekend. Both rural and urban youth with higher levels of CRF had a lower relative risk of being overweight/obese. The observations indicate important associations between weight status and CRF in both rural and urban Portuguese adolescents. In addition, place of residence has an important impact on weight status of this sample of adolescents.     

Taking control of your personal eating and exercise environment: a weight maintenance program

The current investigation examined the impact of a weight maintenance intervention (MI) designed to empower people to create a personal healthy food and physical activity environment on weight loss treatment outcomes. It was hypothesized that behavioral weight loss program (BWLP) participants who received an additional MI would evidence superior weight loss maintenance compared to participants who received a BWLP alone (no contact [NC]). Fifty-one obese adults were randomly assigned to participate in a 16-week weight loss intervention followed by NC or a 6-week MI. Thirty-eight participants completed the six-month follow-up. Body weight, percent body fat, cardiorespiratory fitness, self-reported physical activity, and self-reported diet (i.e., calories, percent daily intake of fat, protein, and carbohydrates) were assessed. Participants significantly decreased their weight, increased physical activity/fitness, and improved dietary intake (ps<.05). MI participants had significantly greater weight loss maintenance than NC participants (ps<.05). Helping obese individuals to modify their personal eating and physical activity environment in order to reduce exposure to "obesogenic" cues may contribute to long-term weight loss maintenance.     

Body Dissatisfaction,Dietary Restraint,Depression, and Weight Status in Adolescents

BACKGROUND: Adolescence may be a crucial period for developing obesity and associated mental health problems. This study examined the relationship of weight status on body image, eating behavior, and depressive symptoms in youth. METHODS: A survey was conducted on 1490 youth attending grades 7–12. Participants completed questionnaires on body image, eating behavior, and mood and were measured for height and weight to calculate body mass index (BMI). Weight classification was based on the International Obesity Task Force guidelines, whereby youth at or above the 95th BMI percentile for age and sex were classified as obese, those between 85th and 94th BMI percentile as overweight, and those between 5th and 84th BMI percentile as normal weight. Several multivariate analyses of variance (MANOVAs) were conducted to examine these relationships. RESULTS: Clear relationships emerged between body image and weight classification. Obese youth reported higher body dissatisfaction than overweight youth, who reported more body dissatisfaction than normal weight youth. These effects were independent of age and gender. A relationship was also found for dietary restraint and weight status whereby higher restraint scores were associated with greater adiposity. Similarly, obese youth reported greater depressive symptoms, including anhedonia, negative self-esteem, and higher overall depression scores compared with overweight and normal-weight youth. CONCLUSIONS: Psychopathology in obese youth is well known in clinical samples but this study suggests that obese youth in the community may be at increased risk of developing body dissatisfaction, dietary restraint, and depressive symptoms compared with overweight or normal weight youth.     

Eating frequency is higher in weight loss maintainers and normal-weight individuals than in overweight individuals

Eating frequency has been negatively related to body mass index (BMI). The relationship between eating frequency and weight loss maintenance is unknown. This secondary analysis examined eating frequency (self-reported meals and snacks consumed per day) in weight loss maintainers (WLM) who had reduced from overweight/obese to normal weight, normal weight (NW) individuals, and overweight (OW) individuals. Data collected July 2006 to March 2007 in Providence, RI, included three 24-hour dietary recalls (2 weekdays, 1 weekend day) analyzed using Nutrient Data System for Research software from 257 adults (WLM n=96, 83.3% women aged 50.0±11.8 years with BMI 22.1±1.7; NW n=80, 95.0% women aged 46.1±11.5 years with BMI 21.1±1.4; OW n=81, 53.1% women aged 51.4±9.0 years with BMI 34.2±4.1) with plausible intakes. Participant-defined meals and snacks were ≥50 kcal and separated by more than 1 hour. Self-reported physical activity was highest in WLM followed by NW, and then OW (3,097±2,572 kcal/week, 2,062±1,286 kcal/week, and 785±901 kcal/week, respectively; P<0.001). Number of daily snacks consumed was highest in NW, followed by WLM, and then OW (2.3±1.1 snacks/day, 1.9±1.1 snacks/day, and 1.5±1.3 snacks/day, respectively; P<0.001). No significant group differences were observed in mean number of meals consumed (2.7±0.4 meals/day). Eating frequency, particularly in regard to a pattern of three meals and two snacks per day, may be important in weight loss maintenance.     

Eating styles, overweight and obesity in young adult twins

OBJECTIVE: To explore the association of eating styles with overweight and obesity in young adults, controlling for identical genetic background in monozygotic twins. DESIGN: Prospective twin cohort study. SETTING: Finland, 1991-2002. SUBJECTS: Two-hundred and thirty-three women and 2060 men from the FinnTwin16 study, aged 16 years at baseline (T1), and ranging from 22 to 27 years at the time of the nutritional assessment (T4). METHODS: Eating styles (Restrictive/overeating, health-conscious, snacking, emotional and externally induced), self-reported at T4, were contrasted with body mass indices (BMIs) at T1 and T4. RESULTS: At T4, obesity (BMI>or=30Kg/m(2)) was significantly cross-sectionally associated with restrictive eating, frequent snacks, eating in the evening, avoiding fatty foods and failure to maintain healthy eating patterns. These associations were independent of BMI at T1. Obese women self-reported more vulnerability to external eating cues and comfort eating than normal-weight women. However, in a multivariable model, only restrictive/overeating and health-conscious eating styles were significant correlates of obesity at T4, independent of gender and BMI at T1. When we controlled for genetic background restricting the analysis to the 39 female and 45 male monozygotic twin pairs discordant for obesity or overweight (BMI>or=25Kg/m(2)), restrictive/overeating eating style was still statistically significantly associated with excess weight. CONCLUSIONS: The eating styles of obese young adults differ from their normal-weight counterparts: restrictive eating, overeating and fewer healthy food choices are associated with obesity. Different eating styles may partially explain weight differences in individuals with identical genetic background.     

Fitness,Food, and Biomarkers: Characterizing Body Composition in 19,634 Early Adolescents

Adolescent obesity persists as a major concern, especially in Central and Eastern Europe, yet evidence gaps exist regarding the pivotal early adolescent years. Our objective was to provide a comprehensive picture using a holistic approach of measured anthropometry in early adolescence, including body composition, cardiorespiratory fitness (CRF), and reported lifestyle characteristics. We aimed to elucidate potential sex/gender differences throughout and associations to biomarkers of disease risk for obese adolescents. Methods: Trained nurses measured 19,634 early adolescents (12–14-year-olds), we collected parental reports, and, for obese adolescents, fasting blood samples in four major Polish cities using a cross-sectional developmental design. Results: 24.7% boys and 18.6% girls were overweight/obese, and 2886 had BMI ≥ 90th percentile. With increasing age, there was greater risk of obesity among boys (p for trend = 0.001) and a decreasing risk of thinness for girls (p for trend = 0.01). Contrary to debate, we found BMI (continuous) was a useful indicator of measured fat mass (FM). There were 38.6% with CRF in the range of poor/very poor and was accounted for primarily by FM in boys, rather than BMI, and systolic blood pressure in girls. Boys, in comparison to girls, engaged more in sports (t = 127.26, p < 0.0001) and consumed more fast food (t = 188.57, p < 0.0001) and sugar-sweetened beverages (167.46, p < 0.0001). Uric acid, a potential marker for prediabetes, was strongly related to BMI in the obese subsample for both boys and girls. Obese girls showed signs of undernutrition. Conclusion: these findings show that overweight/obesity is by far a larger public health problem than thinness in early adolescence and is characterized differentially by sex/gender. Moreover, poor CRF in this age, which may contribute to life course obesity and disease, highlights the need for integrated and personalized intervention strategies taking sex/gender into account.

Cardiovascular Risk Factors and Physical Activity Behavior Among Elementary School Personnel: Baseline Results from the ACTION! Worksite Wellness Program(*)

BACKGROUND: Although the prevalence of obesity is increasing during adulthood, there have been few assessments of obesity, cardiovascular risk factors, and levels of physical activity among adult elementary school staff. METHODS: Data were collected from 745 African-American and White female school personnel in a suburban school district in southeastern Louisiana as part of the baseline assessment before implementation of a program to improve eating and physical activity behaviors. Anthropometry, blood pressure, serum lipids and lipoproteins, and glucose were measured using established protocols. Physical activity was assessed by accelerometry. RESULTS: For both White and Black females, 30% were overweight (body mass index [BMI]) ≥25 kg/m(2) but <30 kg/m(2) ). Whereas 37% of White females were obese (BMI ≥ 30 kg/m(2) ), 61% of the Black females were obese. There was a positive association between BMI and other cardiovascular risk factors except for high-density lipoprotein cholesterol, where the association was negative. The mean number of minutes of daily moderate-to-vigorous physical activity was <1 minute per day and was lower for overweight and obese women than for normal weight women. CONCLUSIONS: School personnel in the study have adverse cardiovascular risk factors, including high rates of obesity and very low levels of physical activity. Because these individuals are often called upon to promote health for children, they are an important target population for wellness interventions.     

The role of anxiety sensitivity in daily physical activity and eating behavior

Anxiety sensitivity (AS), or the fear of somatic arousal, has been linked to both maladaptive eating behavior as well as exercise avoidance in both self-report and laboratory-based experiments. The current pilot study sought to extend these finding to the naturalistic setting. A sample of 32 adults completed affect and dietary monitoring and wore actigraphs across a three-day monitoring period. Results indicated that high AS was associated with greater calorie consumption overall in women and less consumption in men, and high AS predicted an increase in calories consumed following participants' greatest increase in negative affect in both sexes. For physical activity, results indicated an AS by BMI interaction such that obese individuals with high AS engaged in less moderate-intensity physical activity, whereas the opposite was true for normal weight individuals. These results indicate that AS may represent a double-edged risk factor for obesity contributing to both exercise avoidance and calorie consumption.     

Daily physical activity,cardiorespiratory fitness,nutritional status,endothelial function,and autonomic modulation in school-age adolescents: A principal component analysis

PurposeThis study evaluated the association between cardiorespiratory fitness, abdominal obesity, blood pressure, endothelial function, and autonomic modulation in school-age adolescents exhibiting different levels of habitual physical activity and nutritional status, through a multivariate statistical approach.Methods101 adolescents aged 15–18 years (54 females) underwent assessments of daily physical activity, body mass index, cardiorespiratory fitness, reactive hyperemia, and heart rate variability. Based on BMI adjusted for age and sex (z-BMI), 21 adolescents were classified as ‘overweight’ (9 girls), and 9 as ‘obese’ (4 girls). The common variation between those variables was assessed through Principal Component Analysis (PCA).ResultsMain axis of common variation of outcomes analyzed defined four principal components (PCs) accounting for 69.7% of overall variance, related to ‘abdominal obesity and blood pressure’ (PC1; eigenvalue = 2.76), ‘cardiorespiratory fitness, endothelial function, and autonomic modulation’ (PC2, eigenvalue = 1.98), ‘cardiorespiratory fitness’ (PC3, eigenvalue = 1.21), and ‘sedentary behavior’ (PC4, eigenvalue = 1.02). Girls reported longer screen time and sedentary behavior than boys. Notwithstanding, in both sexes poorer cardiorespiratory fitness corresponded to lower reactive hyperemia and vagal modulation, irrespective of the nutritional status. Overall, adolescents classified as ‘obese’ and ‘sedentary’ exhibited poorer CRF concomitantly to autonomic and endothelial dysfunctions.ConclusionIn school-age adolescents, endothelial and autonomic dysfunctions related to poor cardiorespiratory fitness, irrespective of the nutritional status and physical activity level. However, endothelial and autonomic dysfunctions were more prevalent among adolescents combining poor cardiorespiratory fitness, reduced levels of daily physical activity, and overweight/obesity.
