Pediatricians’ Own Weight: Self‐perception,Misclassification, and Ease of Counseling

Objectives: Pediatricians underdiagnose overweight and feel ineffective at counseling. Given the relationship between physicians’ health and health habits and counseling behaviors, we sought to determine the 1) percentage of pediatricians who are overweight; 2) accuracy of pediatricians’ own weight status classification; and 3) relationship between weight self‐perception and perceived ease of obesity counseling. Research Methods and Procedures: This study was a cross‐sectional, mail survey of North Carolina pediatricians that queried about their weight status and ease of counseling. Accuracy of pediatricians’ self‐classification of weight status was compared with BMIs derived from self‐reported height and weight. Using logistic regression, controlling for potential confounding variables, we examined the association between weight perception and ease of counseling. Results: The unadjusted response rate was 62%, and the adjusted response rate was 71% (n = 355). Nearly one‐half (49%) of overweight pediatricians did not identify themselves as such. Men had greater adjusted odds of misclassifying overweight than women [odds ratio (OR), 3.61; 95% confidence interval (CI) = 1.81, 7.21]. Self‐classified “thin” pediatricians had nearly six times the odds of reporting more counseling difficulty as a result of their weight than “average” weight pediatricians (OR = 5.69; 95% CI = 2.30, 14.1), and self‐identified “overweight” pediatricians reported nearly four times as great counseling difficulty as “average” weight physicians (OR = 3.84; 95% CI = 1.11, 13.3), after adjustment for self‐reported BMI weight status and other potential confounders. Discussion: The roles that physician weight misclassification and self‐perception potentially play in influencing rates of obesity counseling warrant further research.     

Management of Obesity in Primary Care

SIMKIN-SILVERMAN, LAUREY R, RENA R WING. Management of obesity in primary care. Obesity is one of the most common presenting chronic medical conditions in primary care, yet it is not adequately treated. Physicians are often reluctant to counsel patients because of their limited training in treating chronic weight problems and negative attitudes toward obese patients. This study evaluated the feasibility of training physicians to provide weight control counseling to their patients. Eleven physicians were randomly assigned to either an obesity-counseling skills training group or to a control group. Physicians in the counseling skills group received training in behavioral and motivational weight control techniques using a five-step patient-centered model; they were also given patient materials for use in their practice. To evaluate pretraining to posttraining changes in physician counseling behavior, independent samples of patients with obesity were surveyed immediately after their visit to the physician's office. Physicians in both the counseling skills training and the control groups discussed weight with 42% to 47% of their patients at baseline. This increased to 89% in physicians who received training, whereas it remained at 42% in control physicians. Scores on a counseling measure also significantly increased from a mean of 2. 7 to 9. 9 in the counseling group, whereas scores in the control group remained low and stable (2. 3 and 1. 9, respectively). The training program was effective in improving the frequency and quality of counseling that physicians delivered to their patients with obesity. Future research is needed to evaluate the effect of physician counseling on the weight and physical activity level of their patients.     

Family Physicians' Practices and Attitudes Regarding Care of Extremely Obese Patients

Despite the growing epidemic of extreme obesity in the United States, weight management is not adequately addressed in primary care. This study assessed family physicians' practices and attitudes regarding care of extremely obese patients and factors associated with them. A cross‐sectional, self‐administered survey was mailed to 500 family physicians in New Jersey (NJ) during March–May 2008. Measures included knowledge, weight management approaches, attitudes toward managing obesity, challenges with examinations, availability of supplies, and strategies to improve care. Response rate was 53% (N = 255). Bariatric surgery and weight loss medications were infrequently recommended, particularly in physicians with higher volume of extremely obese patients (odds ratio (OR) 0.38; 95% confidence interval (CI) 0.23, 0.62 and OR 0.51; 95% CI 0.31, 0.85 for surgery and medications, respectively). Higher knowledge was associated with increased frequency of recommendations of weight loss medications (P < 0.0001) and bariatric surgery (P < 0.0001). There was a high prevalence of negative attitudes, particularly in younger physicians and those with lower patient volume. Increased knowledge of weight‐loss diets was associated with less dislike in discussing weight loss (P < 0.0001), less frustration (P = 0.0001), less belief that treatment is often ineffective (P < 0.0001), and less pessimism about patient success (P = 0.0002). Many providers encountered challenges performing examinations on extremely obese patients. More education of primary care physicians, particularly on bariatric surgery, specific examination techniques, and availability of community resources for obese persons is needed. Further research is needed to determine if interventions to increase knowledge of physicians will lead to less negative attitudes toward weight loss and extremely obese patients.     

Primary Care Physicians’ Attitudes about Obesity and Its Treatment

Objective: This study was designed to assess physicians’ attitudes toward obese patients and the causes and treatment of obesity. Research Methods and Procedures: A questionnaire assessed attitudes in 2 geographically representative national random samples of 5000 primary care physicians. In one sample (N = 2500), obesity was defined as a BMI of 30 to 40 kg/m², and in the other (N = 2500), obesity was defined as a BMI > 40. Results: Six hundred twenty physicians responded. They rated physical inactivity as significantly more important than any other cause of obesity (p < 0.0009). Two other behavioral factors—overeating and a high‐fat diet—received the next highest mean ratings. More than 50% of physicians viewed obese patients as awkward, unattractive, ugly, and noncompliant. The treatment of obesity was rated as significantly less effective (p < 0.001) than therapies for 9 of 10 chronic conditions. Most respondents (75%), however, agreed with the consensus recommendations that a 10% reduction in weight is sufficient to improve obesity‐related health complications and viewed a 14% weight loss (i.e., 78 ± 5 kg from an initial weight of 91 kg) as an acceptable treatment outcome. More than one‐half (54%) would spend more time working on weight management issues if their time was reimbursed appropriately. Discussion: Primary care physicians view obesity as largely a behavioral problem and share our broader society's negative stereotypes about the personal attributes of obese persons. Practitioners are realistic about treatment outcomes but view obesity treatment as less effective than treatment of most other chronic conditions.     

Management of Obesity: A Challenge for Medical Training and Practice

Health‐care providers are in a unique position to encourage people to make healthy lifestyle choices. However, lifestyle modification counseling is a complex task, made even more so by the cultural and socioeconomic diversity of patient populations. The objective of this study is to evaluate the prevalence and predictors of attending and physician‐in‐training weight control counseling in an urban academic internal medicine clinic serving a unique low‐income multiethnic high‐risk population. In 2006, patients (n = 256) from the Associates in Internal Medicine clinic (Division of General Medicine at the New York Presbyterian Hospital, Columbia University Medical Center, New York, NY) were recruited and completed a questionnaire, which assessed demographic variables, health conditions, access to health‐care services, physician weight control counseling, and weight loss attempts. Seventy‐nine percent of subjects were either overweight or obese. Only 65% of obese subjects were advised to lose weight. Attending physicians were more likely than physicians‐in‐training to counsel subjects on weight control (P < 0.01). Factors that were significantly (P < 0.05) associated with different types of weight control counseling included obesity, cardiovascular disease (CVD) risk factors, female gender, nonblack race, college education, married status, and attending physician. Subjects advised to lose weight were more likely to report an attempt to lose weight (P < 0.01). Rates of weight control counseling among physicians are suboptimal, particularly among physicians‐in‐training. Training programs need to promote effective clinical obesity prevention and treatment strategies that address socioeconomic, linguistic, and cultural factors.     

Recognition of Childhood Overweight during Health Supervision Visits: Does BMI Help Pediatricians?

Objective: To assess, in diverse pediatric practices, the frequency of overweight/obesity (OW/OB) identification during health supervision visits and its association with BMI curve use. Research Methods and Procedures: Pediatricians in public and private practice in St. Louis, MO, participated in a study of the care of chronic conditions during health supervision visits. Requested information from 30 visits per pediatrician of children 6 to 17 years of age included the visit note, the growth chart, and a one‐page questionnaire about patient demographics and visit content. Pediatricians indicated the presence and discussion of common chronic conditions, including OW/OB. Identification was compared with patient BMI category, and associations between identification and patient and visit characteristics, including BMI curve use, were examined. Results: Twenty‐one (40%) of contacted pediatricians returned information from 557 visits. Pediatricians identified OW/OB in 27% of children with a BMI at the 85th to 94th percentile and 86% of children with a BMI at or above the 95th percentile. Identification was higher in adolescents but was not associated with patient sex or race, practice setting, insurance type, or visit length. Only 41% of growth charts were current, and 6.1% had BMI plotted. BMI plotting was associated with OW/OB identification when the BMI was at the 85th to 94th percentile but not when the BMI was at or above the 95th percentile. After controlling for BMI percentile, OW/OB identification was significantly associated with diet counseling (odds ratio, 7.46; 95% confidence interval, 3.42 to 16.24) and exercise counseling (odds ratio, 5.57; 95% confidence interval, 2.61 to 11.90). Discussion: Despite low BMI curve use, pediatricians recognized most overweight/obese children with a BMI at or above the 95th percentile. BMI plotting may increase recognition in mildly overweight children.     

Association of maternal lifestyles including smoking during pregnancy with childhood obesity

Objective: To examine the extent to which maternal smoking during early pregnancy and other prepregnancy lifestyle habits are associated with obesity and overweight in 5‐year‐old Japanese children. Research Method and Procedures: We studied 1417 mother‐child pairs enrolled in Project Enzan—a prospective cohort study. The dependent variables, childhood overweight and obesity, were defined with an international cut‐off value. Maternal smoking during early pregnancy and other prepregnancy lifestyle habits were used as independent variables. Results: Maternal smoking habits were associated with overweight in the 5‐year‐old children [adjusted odds ratio (OR): 2.15; 95% confidence interval (CI): 1.12 to 4.11]. Maternal sleep duration of ≥8 h/d negatively affected childhood overweight (adjusted OR: 0.71; 95% CI: 0.49 to 1.04). Children whose mothers skipped breakfast were likely to become overweight (adjusted OR: 1.78; 95% CI: 1.14 to 2.77). The results of childhood obesity analysis were similar to those of childhood overweight analysis. Discussion: The results of this study suggest that there are effects of smoking during early pregnancy and other maternal lifestyle habits on the onset of childhood obesity in Japan. Therefore, interventions in maternal lifestyle habits are required to prevent childhood obesity, and these interventions should be initiated before pregnancy.     

Adherence to vitamin supplementation following adolescent bariatric surgery

Objective: Adolescents with extreme obesity, who have undergone bariatric surgery, must adhere to many lifestyle and nutritional recommendations, including multivitamin therapy. Little is known about multivitamin adherence following adolescent bariatric surgery. Design and Methods: The present study aims to document self‐reported and electronically‐monitored adherence to multivitamins, determine convergence between self‐report and electronic monitoring adherence for multivitamins, and identify barriers to multivitamin adherence for adolescents who have undergone bariatric surgery. Results: The study used a prospective, longitudinal observational design to assess subjective (self‐reported) and objective (electronic monitors) multivitamin adherence in a cohort of 41 adolescents (Mean age = 17.1 ± 1.5; range = 13‐19) who have undergone bariatric surgery at Cincinnati Children's Hospital Medical Center. Mean adherence as derived from electronic monitoring for the entire 6‐month study period was 29.8% ± 23.9. Self‐reported adherence was significantly higher than electronically monitored adherence across both the 1 and 6‐month assessment points (z = 4.5, P < 0.000 and z = 4.0, P < 0.0001, respectively). Forgetting and difficulty swallowing multivitamins were the two primary barriers identified. While there are no established data regarding best practice for multivitamins following bariatric surgery, high rates of nonadherence to multivitamin therapy were observed in adolescents who had undergone bariatric surgery with forgetting and difficulty swallowing pills as reported barriers to adherence. Conclusion: These high rates of nonadherence to multivitamin therapy should be considered when devising treatment and family education pathways for adolescents considering weight loss surgery.     

Utility of Childhood BMI in the Prediction of Adulthood Disease: Comparison of National and International References

Objective: 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.     

Stigmatizing attitudes toward obesity in a representative population-based sample

Objective: The aim of this study was to determine stigmatizing attitudes toward obesity in the population, and its related psychological and sociodemographic determinants. Methods and Procedures: In a representative population‐based survey (N = 1,000), computer‐assisted telephone interviewing was used to assess stigmatizing attitudes toward obesity, causal attributions of obesity, the labeling of obesity as an illness, perceptions about prevalence, severity, and chronicity of obesity, support of obesity prevention, and sociodemographic characteristics. Results: Of the 1,000 participants, 23.5% (n = 235) had stigmatizing attitudes toward obesity, 21.5% (n = 215) did not have stigmatizing attitudes toward obesity, and 55.0% (n = 550) had attitudes that were undetermined with respect to stigmatization. Predictors of greater stigmatization were more causal attributions of obesity to individual behavior, less education, and older age, while causal attributions of obesity to heredity and labeling obesity as an illness predicted less stigmatization. Stigmatizing attitudes were significantly associated with stronger overall support of obesity prevention, but less readiness to support prevention financially. Discussion: Our results indicate that stigmatizing attitudes toward obesity are prevalent in the population. Information about the etiology of obesity and the clinical relevance of this condition could prove useful for destigmatization efforts.     

Race, childhood insulin, childhood caloric intake, and class 3 obesity at age 24: 14-year prospective study of schoolgirls

The prevalence of Class 3 obesity (BMI ≥40 kg/m²) has more than doubled in the past 25 years. In a 14‐year prospective study from age 10 to 24 of a biracial schoolgirl cohort (293 black, 256 white), we assessed childhood correlates of Class 3 BMI at age 24. Of 42 girls with Class 3 BMI at age 24, 36 (86%) were black. By logistic regression, significant explanatory variables of Class 3 BMI at age 24 included top decile waist circumference at age 11 (odds ratio (OR) 5.7, 95% confidence interval (CI) 2.3–13.9, P = 0.0002), age 10 BMI ≥ the Center for Disease Control (CDC) 2000 top 15% (OR 7.0, 95% CI 2.5–19.3, P = 0.0002), and a three‐way interaction between race, childhood insulin, and average caloric intake from age 10 to age 19 (for each unit increase, OR 1.7 95% CI 1.3–2.2, P = 0.0003). Age 10 BMI, age 11 waist circumference, and interaction of race, childhood insulin, and childhood caloric intake predict Class 3 obesity in young adulthood, facilitating childhood identification of girls at high risk for developing Class 3 obesity.     

Trust in scientific experts on obesity: implications for awareness and behavior change

Objective: To explore the relationship between public trust in scientific experts on obesity and public attention to nutrition recommendations, to investigate trust as a predictor of weight‐related behaviors, and to identify the sociodemographic characteristics associated with high and low trust in scientific experts on obesity. Research Methods and Procedures: This analysis used survey data from two sources: 1) a 2005 Harvard School of Public Health Obesity Survey (N = 2033), and 2) the 2004 General Social Survey (N = 2812). Five outcome measures were used. Three were used to explore trust as a predictor of attention and weight‐related behaviors. Two were used to identify the sociodemographic predictors of trust. Logistic regression analysis was used to model the outcome variables. Results: Trust in scientific experts was the strongest predictor of public attention to nutritional recommendations from scientific experts, but it was not directly related to weight‐related behaviors. Public attention was significantly associated with two weight‐related behaviors: tracking fruit and vegetable intake and exercise. Women and more educated individuals had significantly higher odds of trusting scientific experts. Characteristics associated with distrust in scientific experts included Hispanic race and older age (over 50). Discussion: Public health experts should work toward building trust as an important step in stemming the obesity epidemic. Further, more research is necessary to better understand the factors driving trust in scientific experts on obesity. A deeper insight in this area will certainly be of great benefit to obesity‐related risk communication and potentially lead to positive behavior change.     

Additive Interactions of Maternal Prepregnancy BMI and Breast‐feeding on Childhood Overweight

Objective: To examine the interactions of maternal prepregnancy BMI and breast‐feeding on the risk of overweight among children 2 to 14 years of age. Research Methods and Procedures: The 1996 National Longitudinal Survey of Youth, Child and Young Adult data in the United States were analyzed (n = 2636). The weighted sample represented 51.3% boys, 78.0% whites, 15.0% blacks, and 7.0% Hispanics. Childhood overweight was defined as BMI ≥95th percentile for age and sex. Maternal prepregnancy obesity was determined as BMI ≥30 kg/m². The duration of breast‐feeding was measured as the weeks of age from birth when breast‐feeding ended. Results: After adjusting for potential confounders, children whose mothers were obese before pregnancy were at a greater risk of becoming overweight [adjusted odds ratio (OR), 4.1; 95% confidence interval (CI), 2.6, 6.4] than children whose mothers had normal BMI (<25 kg/m²; p < 0.001 for linear trend). Breast‐feeding for ≥4 months was associated with a lower risk of childhood overweight (OR, 0.6; 95% CI, 0.4, 1.0; p = 0.06 for linear trend). The additive interaction between maternal prepregnancy obesity and lack of breast‐feeding was detected (p < 0.05), such that children whose mothers were obese and who were never breast‐fed had the greatest risk of becoming overweight (OR, 6.1; 95% CI, 2.9, 13.1). Discussion: The combination of maternal prepregnancy obesity and lack of breast‐feeding may be associated with a greater risk of childhood overweight. Special attention may be needed for children with obese mothers and lack of breast‐feeding in developing childhood obesity intervention programs.     

Racial and ethnic differences in pediatric obesity-prevention counseling: national prevalence of clinician practices

Objective: To assess the frequency of clinician‐reported delivery of obesity‐prevention counseling (OPC) at well‐child visits; evaluating for racial/ethnic discrepancies. Methods and Procedures: Combined, weighted well‐child visit data from the National Ambulatory Medical Care Survey (NAMCS) and National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2001 to 2004 were analyzed for patients aged 4–18 years. Obesity‐prevention counseling was defined as the combined delivery of diet/nutrition and exercise counseling. Patients receiving over‐ or underweight related diagnoses were excluded. Counseling frequencies were calculated. Multivariate logistic regression models examined the relationship of OPC with race, ethnicity, region, provider, sex, age, and payor type. Results: Of 55,695,554 (weighted) visits, 24.4% included OPC (90.8% of these from NAMCS). 15.4% of Hispanic patients received OPC compared to 28.8% of non‐Hispanics. Frequencies were similar between Whites and Blacks (25.0 and 27.1%). Patients with private insurance received more counseling (26.9%) than Medicaid (19.1%) or self‐pay (15.1%). In logistic regression models, non‐Hispanics were more likely to receive OPC (odds ratio (OR) = 1.94; confidence interval (CI) = 1.13–3.32), and patients in the West were less likely to receive OPC (OR = 0.39; CI = 0.18–0.85). Payor type was not predictive in regression analysis. Patients in hospital‐based practices received less OPC (11.9% vs. 25.7% with OR = 0.40; CI =0.22–0.74). Discussion: Obesity prevention, like treatment, is a complex and multifactorial process. With the documented racial and ethnic disparities in rates of pediatric obesity, reasons for discrepancies in the provision of OPC must be further investigated as preventive strategies are formulated.     

Disparity in Physician Perception of Patients' Adherence to Medications by Obesity Status

Physician perception of medication adherence may alter prescribing patterns. Perception of patients has been linked to readily observable factors, such as race and age. Obesity shares a similar stigma to these factors in society. We hypothesized that physicians would perceive patients with a higher BMI as nonadherent to medication. Data were collected from the baseline visit of a randomized clinical trial of patient–physician communication (240 patients and 40 physicians). Physician perception of patient medication adherence was measured on a Likert scale and dichotomized as fully adherent or not fully adherent. BMI was the predictor of interest. We performed Poisson regression analyses with robust variance estimates, adjusting for clustering of patients within physicians, to examine the association between BMI and physician perception of medication adherence. The mean (s.d.) BMI was 32.6 (7.7) kg/m². Forty‐five percent of patients were perceived as nonadherent to medications by their physicians. Higher BMI was significantly and negatively associated with being perceived as adherent to medication (prevalence ratio (PrR) 0.76, 95% confidence interval (CI): 0.64–0.90; P = 0.002; per 10 kg/m² increase in BMI). BMI remained significantly and negatively associated with physician perception of medication adherence after adjustment for patient and physician characteristics (PrR 0.80, 95% CI: 0.66–0.96; P = 0.020). In this study, patients with higher BMI were less likely to be perceived as adherent to medications by their providers. Physician perception of medication adherence has been shown to affect prescribing patterns in other studies. More work is needed to understand how this perception may affect the care of patients with obesity.     

Major Increase in Prevalence of Overweight and Obesity between 1987 and 2001 among Danish Adults

Objective: The aim of the study was to examine the secular trends in the prevalence of obesity (BMI ≥ 30.0 kg/m²) and overweight (25.0 ≤ BMI < 30.0 kg/m²) in Danish adults between 1987 and 2001. Research Methods and Procedures: The study included self‐reported weight and height of 10, 094 men and 9897 women 16 to 98 years old, collected in a series of seven independent cross‐sectional surveys. Prevalence and changes in prevalence of obesity and overweight stratified by sex and age groups were determined Results: The prevalence of obesity more than doubled between 1987 and 2001, in men from 5.6% to 11.8% [odds ratio (OR) = 2.3, 95% confidence interval (CI) = 1.9 to 2.8, p < 0.0001] and in women from 5.4% to 12.5% (OR = 2.6, 95% CI = 2.1 to 3.2, p < 0.0001), with the largest increase among the 16‐ to 29‐year‐old subjects (men, from 0.8% to 7.5%, OR = 10.2, 95% CI = 4.1 to 25.3, p < 0.0001; women, from 1.4% to 9.0% OR = 7.0, 95% CI = 3.5 to 14.1, p < 0.0001). Between 1987 and 2001, the prevalence of overweight increased from 34% to 40% in men and from 17% to 27% in women. Discussion: The prevalence of overweight and obesity in Denmark has increased substantially between 1987 and 2001, particularly among young adults, a development that resembles that of other countries. There is clearly a need for early preventive efforts in childhood to limit the number of obesity‐related complications in young adults.     

Diet and Physical Activity Behaviors among Americans Trying to Lose Weight: 2000 Behavioral Risk Factor Surveillance System

Objective: To examine the prevalence and correlates of trying to lose weight among U.S. adults, describe weight loss strategies, and assess attainment of recommendations for weight control (eating fewer calories and physical activity). Research Methods and Procedures: This study used the Behavioral Risk Factor Surveillance System, a state‐based telephone survey of adults ≥18 years of age (N = 184, 450) conducted in the 50 states, the District of Columbia, and Puerto Rico in 2000. Results: The prevalence of trying to lose weight was 46% (women) and 33% (men). Women reported trying to lose weight at a lower BMI than did men; 60% of overweight women were trying to lose weight, but men did not reach this level until they were obese. Adults who had a routine physician checkup in the previous year and reported medical advice to lose weight vs. checkup and no medical advice to lose weight had a higher prevalence of trying to lose weight (81% women and 77% men vs. 41% women and 28% men, respectively). The odds of trying to lose weight increased as years of education increased. Among respondents who were trying to lose weight, ～19% of women and 22% of men reported using fewer calories and ≥150 min/wk leisure‐time physical activity. Discussion: A higher percentage of women than men were trying to lose weight; both sexes used similar weight loss strategies. Education and medical advice to lose weight were strongly associated with trying to lose weight. Most persons trying to lose weight were not using minimum recommended weight loss strategies.     

Disability,Arthritis, and Body Weight among Adults 45 Years and Older

Objectives : To examine the association between body weight and disability among persons with and without self‐reported arthritis. Research Methods and Procedures : Data were analyzed for noninstitutionalized adults, 45 years or older, in states that participated in the Behavioral Risk Factor Surveillance System. Self‐reported BMI (kilograms per meter squared) was used to categorize participants into six BMI‐defined groups: underweight (<18.5), normal weight (18.5 to <25), overweight (25 to <30), obese, class 1 (30 to <35), obese, class 2 (35 to <40), and obese, class 3 (≥40). Results : Class 3 obesity (BMI ≥ 40) was significantly associated with disability among participants both with and without self‐reported arthritis. The adjusted odds ratio (AOR) for disability in participants with class 3 obesity was 2.75 [95% confidence interval (CI) = 2.22 to 3.40] among those with self‐reported arthritis and 1.77 (95% CI = 1.20 to 2.62) among those without self‐reported arthritis compared with those of normal weight (BMI 18.5 to <25). Persons with self‐reported arthritis who were obese, class 2 (BMI 35 to <40) and obese, class 1 (BMI 30 to <35) and women with self‐reported arthritis who were overweight (BMI 25 to <30) also had higher odds of disability compared with those of normal weight [AOR = 1.72 (95% CI = 1.47 to 2.00), AOR = 1.30 (95% CI = 1.17 to 1.44), and AOR = 1.18 (95% CI = 1.06 to 1.32), respectively]. Discussion : Our findings reveal that obesity is associated with disability. Preventing and controlling obesity may improve the quality of life for persons with and without self‐reported arthritis.     

Meal Frequency and Childhood Obesity

Objective: Previous studies have demonstrated an inverse association between meal frequency and the prevalence of obesity in adulthood. The aim of this study was to assess the relationship between meal frequency and childhood obesity. Research Methods and Procedures: Stature and weight of 4370 German children ages 5 to 6 years were determined in six Bavarian (Germany) public health offices during the obligatory school entry health examination in 2001/2002. An extensive questionnaire on risk factors for obesity was answered by their parents. Obesity was defined according to sex‐ and age‐specific BMI cut‐off points proposed by the International Obesity Task Force. The main exposure was daily meal frequency. Results: The prevalence of obesity decreased by number of daily meals: three or fewer meals, 4.2% [95% confidence interval (CI), 2.8 to 6.1]; four meals, 2.8% (95% CI, 2.1 to 3.7); and 5 or more meals, 1.7% (95% CI, 1.2 to 2.4). These effects could not be explained by confounding due to a wide range of constitutional, sociodemographic, and lifestyle factors. The adjusted odds ratios for obesity were 0.73 (95% CI, 0.44 to 1.21) for four meals and 0.51 (95% CI, 0.29 to 0.89) for five or more meals. Additional analyses pointed to a higher energy intake in nibblers compared with gorgers. Discussion: A protective effect of an increased daily meal frequency on obesity in children was observed and appeared to be independent of other risk factors for childhood obesity. A modulation of the response of hormones such as insulin might be instrumental.     

Stigmatized Students: Age,Sex, and Ethnicity Effects in the Stigmatization of Obesity

Objective: 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.
