Physician practice patterns of obesity diagnosis and weight-related counseling

Healthcare provider accuracy at estimating women's BMI and intent to provide counseling based on appearance alone

OBJECTIVE

To assess healthcare providers' ability to estimate women's body mass index (BMI) based on physical appearance and determine the prevalence of, and barriers to, weight-related counseling.

METHODS

A web-based survey was distributed to healthcare providers ("participants") at a university-based hospital and contained photographs of anonymous women ("photographed women (PW)") as well as questions regarding participant demographics. Participants were asked to estimate BMI category based on physical appearance, state whether they would provide weight-loss counseling for each PW and identify barriers to counseling.

RESULTS

One hundred forty-two participants completed the survey. BMI estimations were poor among all participants, with an overall accuracy of only 41% and a large proportion of underestimations. Standardization of PW clothing did not improve accuracy; 41% for own clothing versus 40% for scrubs, P = 0.2. BMI assessments were more accurate for Caucasian versus African American PW (45% versus 36%, P < 0.001) and PW with normal weight (84%) and obesity III (38%) compared to PW with mid-range BMI (P < 0.001). Although the frequency of weight loss counseling was positively associated with PW BMI, participants only intended to counsel 69% of overweight and obese PW. The most commonly cited reason for lack of counseling was time constraints (54%).

CONCLUSIONS

Healthcare providers are inaccurate at appearance-based BMI categorization and thus, BMI should be routinely calculated in order to improve identification of those in need of counseling. When appropriately identified, time constraints may prevent practitioners from providing appropriate weight-loss counseling-further complicating the already difficult task of fighting obesity.

A cross-sectional study examining Australian general practitioners' identification of overweight and obese patients

BACKGROUND

Overweight and obese patients attempt weight loss when advised to do so by their physicians; however, only a small proportion of these patients report receiving such advice. One reason may be that physicians do not identify their overweight and obese patients.

OBJECTIVES

We aimed to determine the extent that Australian general practitioners (GP) recognise overweight or obesity in their patients, and to explore patient and GP characteristics associated with non-detection of overweight and obesity.

METHODS

Consenting adult patients (n = 1,111) reported weight, height, demographics and health conditions using a touchscreen computer. GPs (n = 51) completed hard-copy questionnaires indicating whether their patients were overweight or obese. We calculated the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for GP detection, using patient self-reported weight and height as the criterion measure for overweight and obesity. For a subsample of patients (n = 107), we did a sensitivity analysis with patient-measured weight and height. We conducted an adjusted, multivariable logistic regression to explore characteristics associated with non-detection, using random effects to adjust for correlation within GPs.

RESULTS

Sensitivity for GP assessment was 63 % [95 % CI 57-69 %], specificity 89 % [95 % CI 85-92 %], PPV 87 % [95 % CI 83-90 %] and NPV 69 % [95 % CI 65-72 %]. Sensitivity increased by 3 % and specificity was unchanged in the sensitivity analysis. Men (OR: 1.7 [95 % CI 1.1-2.7]), patients without high blood pressure (OR: 1.8 [95 % CI 1.2-2.8]) and without type 2 diabetes (OR: 2.4 [95 % CI 1.2-8.0]) had higher odds of non-detection. Individuals with obesity (OR: 0.1 [95 % CI 0.07-0.2]) or diploma-level education (OR: 0.3 [95%CI 0.1-0.6]) had lower odds of not being identified. No GP characteristics were associated with non-detection of overweight or obesity.

CONCLUSIONS

GPs missed identifying a substantial proportion of overweight and obese patients. Strategies to support GPs in identifying their overweight or obese patients need to be implemented.

Perceptions of Midwest rural women related to their physical activity and eating behaviors

The study aim was to describe the perceptions of 65 Midwestern rural women related to healthy eating, physical activity, and weight management. A semistructured interview guide was used to elicit data. Theory of planned behavior constructs were used to categorize the data into 4 predominant themes related to healthy lifestyle behaviors, (a) knowledge and attitudes, (b) rural cultural influences, (c) facilitators, and (d) barriers. Analyses revealed that facilitators and barriers consisted of social and environmental factors, and personal life situations. Results suggest key elements for developing and implementing effective physical activity and weight management interventions for Midwestern rural women.

Accuracy and congruence of patient and physician weight-related discussions: from project CHAT (Communicating Health: Analyzing Talk)

OBJECTIVE

Primary care providers should counsel overweight patients to lose weight. Rates of self-reported, weight-related counseling vary, perhaps because of self-report bias. We assessed the accuracy and congruence of weight-related discussions among patients and physicians during audio-recorded encounters.

METHODS

We audio-recorded encounters between physicians (n = 40) and their overweight/obese patients (n = 461) at 5 community-based practices. We coded weight-related content and surveyed patients and physicians immediately after the visit. Generalized linear mixed models assessed factors associated with accuracy.

RESULTS

Overall, accuracy was moderate: patient (67%), physician (70%), and congruence (62%). When encounters containing weight-related content were analyzed, patients (98%) and physicians (97%) were highly accurate and congruent (95%), but when weight was not discussed, patients and physicians were more inaccurate and incongruent (patients, 36%; physicians, 44%; 28% congruence). Physicians who were less comfortable discussing weight were more likely to misreport that weight was discussed (odds ratio, 4.5; 95% confidence interval, 1.88-10.75). White physicians with African American patients were more likely to report accurately no discussion about weight than white physicians with white patients (odds ratio, 0.30; 95% confidence interval, 0.13-0.69).

CONCLUSION

Physician and patient self-report of weight-related discussions were highly accurate and congruent when audio-recordings indicated weight was discussed but not when recordings indicated no weight discussions. Physicians' overestimation of weight discussions when weight is not discussed constitutes missed opportunities for health interventions.

Metabolic Syndrome and its Profound Effect on Prevalence of Ischemic Stroke

Ischemic stroke represents a leading cause of death worldwide and the leading cause of disability in the United States. Greater than 8% of all deaths are attributed to ischemic stroke. This rate is consistent with the heightened burden of cardiovascular disease deaths. Treatments for acute ischemic stroke remain limited to tissue plasminogen activator and mechanical thrombolysis, both of which require significant medical expertise and can only be applied to a select number of patients based on time of presentation, imaging, and absence of contraindications. Over 1,000 compounds that were successful in treating ischemic stroke in animal models have failed to correlate to success in clinical trials. The search for alternative treatments is ongoing, drawing greater attention to the importance of preclinical models that more accurately represent the clinical population through incorporation of common risk factors. This work reviews the contribution of these commonly observed risk factors in the clinical population highlighting both the pathophysiology as well as current clinical diagnosis and treatment standards. We also highlight future potential therapeutic targets, areas requiring further investigation, and recent changes in best-practice clinical care.

Insights from the POWER practice-based weight loss trial: a focus group study on the PCP's role in weight management

BACKGROUND

Despite U.S. Preventive Services Task Force recommendations, few primary care providers (PCPs) counsel obese patients about weight loss. The POWER practice-based weight loss trial used health coaches to provide weight loss counseling, but PCPs referred their patients and reviewed their patients' progress reports. This trial provided a unique opportunity to understand PCPs' actual and desired roles in a multi-component weight loss intervention.

OBJECTIVE

1) To explore the PCP role, inclusive of and beyond the trial's intended role, in a practice-based weight loss trial; and 2) to elicit recommendations by PCPs for wider dissemination of the successful multi-component program.

DESIGN

Qualitative focus group study of PCPs with ≥ 4 patients enrolled in trial.

PARTICIPANTS

Twenty-six out of 30 PCPs from six community practices participated between June and August 2010.

MAIN MEASURES

We used a semi-structured moderator guide. Focus groups were audio-recorded and transcribed verbatim. Two investigators independently coded transcripts for thematic content, identified meaningful segments within the responses and assigned codes using an editing style analysis. Atlas.ti software was used for organization/analysis.

MAIN RESULTS

We identified five major themes related to the PCP's role in patients' weight management: (1) refer patients into program, provide endorsement; (2) provide accountability for patients; (3) "cheerlead" for patients during visits; (4) have limited role in weight management; and (5) maintain the long-term trusting relationship through the ups and downs. PCPs provided several recommendations for wider dissemination of the program into primary care practices, highlighting the need for specific feedback from coaches as well as efficient, integrated processes.

CONCLUSIONS

Weight loss programs have the potential to partner with PCPs to build upon the patient-provider relationship to improve patient accountability and sustain behavior change. However, rather than directing the weight loss, PCPs preferred a peripheral role by utilizing health coaches.

Economic analyses of the Be Fit Be Well program: a weight loss program for community health centers

BACKGROUND

The U.S. Preventive Services Task Force has released new guidelines on obesity, urging primary care physicians to provide obese patients with intensive, multi-component behavioral interventions. However, there are few studies of weight loss in real world nonacademic primary care, and even fewer in largely racial/ethnic minority, low-income samples.

OBJECTIVE

To evaluate the recruitment, intervention and replications costs of a 2-year, moderate intensity weight loss and blood pressure control intervention.

DESIGN

A comprehensive cost analysis was conducted, associated with a weight loss and hypertension management program delivered in three community health centers as part of a pragmatic randomized trial.

PARTICIPANTS

Three hundred and sixty-five high risk, low-income, inner city, minority (71 % were Black/African American and 13 % were Hispanic) patients who were both hypertensive and obese.

MAIN MEASURES

Measures included total recruitment costs and intervention costs, cost per participant, and incremental costs per unit reduction in weight and blood pressure.

KEY RESULTS

Recruitment and intervention costs were estimated $2,359 per participant for the 2-year program. Compared to the control intervention, the cost per additional kilogram lost was $2,204 /kg, and for blood pressure, $621 /mmHg. Sensitivity analyses suggest that if the program was offered to a larger sample and minor modifications were made, the cost per participant could be reduced to the levels of many commercially available products.

CONCLUSIONS

The costs associated with the Be Fit Be Well program were found to be significantly more expensive than many commercially available products, and much higher than the amount that the Centers for Medicare and Medicaid reimburse physicians for obesity counseling. However, given the serious and costly health consequences associated with obesity in high risk, multimorbid and socioeconomically disadvantaged patients, the resources needed to provide interventions like those described here may still prove to be cost-effective with respect to producing long-term behavior change.

District nurses' self-reported clinical activities, beliefs about and attitudes towards obesity management

AIM

To describe district nurses' self-reported clinical activities, beliefs about and attitudes towards obesity management; and to examine associations between the variables.

BACKGROUND

Obesity is increasing worldwide and primary care could play a central role in the management.

METHODS

Questionnaire data were collected from 247 nurses in 33 centres.

RESULTS

The most common activities performed weekly were; advice about physical activity (40.1%) and general lifestyle advice (34.8%). However, nearly one third seldom/never performed these activities. Approximately half seldom/never performed BMI assessment and even fewer waist circumference (78.1%). Values for the factors Importance of obesity and Personal effectiveness were skewed towards a positive view and Negative view close to neutral. Multivariate analysis revealed that nurses with specialized tasks, longer working experience and higher perceived personal effectiveness performed more clinical activities.

CONCLUSION

Managers need to make efforts to engage all personnel in obesity management; and strategies to increase self-efficacy are called for.

Variations between obese Latinos and whites in weight-related counseling during preventive clinical visits in the United States

OBJECTIVE

To examine rate differences and explanatory factors for lifestyle counseling to obese Latinos versus non-Hispanic whites (NHWs) in U.S. outpatient settings.

DESIGN AND METHODS

The 2009 National Ambulatory Medical Care Survey data assessed the provision of weight-related lifestyle counseling during general medical exam visits (n = 688) by obese Latino and NHW adults. The Blinder-Oaxaca decomposition technique to identify the fraction of the overall ethnic difference in counseling rate explained by a selection of measured variables based on the Anderson-Newman-Aday behavioral model were used.

RESULTS

Although weight-related lifestyle counseling rates were low in both ethnic groups, the rate among obese Latinos (51.3%) was significantly higher than among NHWs (35.8%) (P = 0.03), with 60% of the difference explained by observed factors. Enabling factors such as provider specialty, metropolitan statistical area, practice type, and provider employment type contributed the most to higher counseling rates among Latinos, whereas geographic region, continuity of care, and health insurance were enabling factors that, along with the predisposing factor of sex, contributed the most in the opposite direction.

CONCLUSIONS

Obese Latinos are more likely to receive weight-related counseling during general medical exams than do NHWs, which is partly explained by physician practice and patient factors.

Women weigh in: obese African American and White women's perspectives on physicians' roles in weight management

BACKGROUND

There is little qualitative research on the type of weight loss counseling patients prefer from their physicians and whether preferences differ by race.

METHODS

This qualitative study used semistructured, in-depth interviews of 33 moderately to severely obese white and African American women to elucidate and compare their perceptions regarding their primary care physician's approach to weight loss counseling. Data were analyzed using a grounded theory approach and a series of immersion/crystallization cycles.

RESULTS

White and African American women seemed to internalize weight stigma differently. African American participants spoke about their pride and positive body image, whereas white women more frequently expressed self-deprecation and feelings of depression. Despite these differences, both groups of women desired similar physician interactions and weight management counseling, including (1) giving specific weight loss advice and individualized plans for weight management; (2) addressing weight in an empathetic, compassionate, nonjudgmental, and respectful manner; and (3) providing encouragement to foster self-motivation for weight loss.

CONCLUSION

While both African American and white women desired specific strategies from physicians in weight management, some white women may first need assistance in overcoming their stigma, depression, and low self-esteem before attempting weight loss.

National survey of US primary care physicians' perspectives about causes of obesity and solutions to improve care

OBJECTIVE

To describe physician perspectives on the causes of and solutions to obesity care and identify differences in these perspectives by number of years since completion of medical school.

DESIGN

National cross-sectional online survey from 9 February to 1 March 2011.

SETTING

USA.

PARTICIPANTS

500 primary care physicians.

MAIN MEASURES

We evaluated physician perspectives on: (1) causes of obesity, (2) competence in treating obese patients, (3) perspectives on the health professional most qualified to help obese patients lose or maintain weight and (4) solutions for improving obesity care.

RESULTS

Primary care physicians overwhelmingly supported additional training (such as nutrition counselling) and practice-based changes (such as having scales report body mass index) to help them improve their obesity care. They also identified nutritionists/dietitians as the most qualified providers to care for obese patients. Physicians with fewer than 20 years since completion of medical school were more likely to identify lack of information about good eating habits and lack of access to healthy food as important causes of obesity. They also reported feeling relatively more successful helping obese patients lose weight. The response rate for the survey was 25.6%.

CONCLUSIONS

Our results indicate a perceived need for improved medical education related to obesity care.

Primary care providers' communication with patients during weight counseling: a focus group study

OBJECTIVE

Primary care providers (PCPs) are encouraged to counsel their obese patients about weight loss. We used focus groups to explore how PCPs communicate with patients about weight management.

METHODS

During the summer of 2010, we conducted five focus groups of community-based PCPs who had patients enrolled in a practice-based, randomized controlled weight loss trial in Maryland. Focus groups were audio-recorded and transcribed verbatim. Two investigators independently coded transcripts for thematic content using editing style analysis.

RESULTS

Twenty-six PCPs from six different practices participated. Mean years in practice were 16.4 (SD 11.7) and 77% practiced internal medicine. We identified three communication-based themes about weight loss counseling: (1) motivating patients to lose weight, (2) partnering with the patient to achieve weight loss, and (3) handling challenges that arise during weight counseling.

CONCLUSION

PCPs use a variety of strategies to communicate with their patients about weight loss. Some PCPs already use patient-centered approaches to communicate with their patients about weight loss, suggesting that future weight counseling interventions should be tailored to build upon this strength.

PRACTICE IMPLICATIONS

PCPs' weight loss counseling may be improved by using techniques with demonstrated behavior change effectiveness such as the 5A's or motivational interviewing.

Trends in nutrition and exercise counseling among adolescents in the health care environment

PURPOSE

Obesity is a serious health threat, particularly among racial/ethnic minorities and those who are uninsured, yet little is known about the implementation of nutrition or exercise counseling or the combination of both among these groups. Trends in counseling by race/ethnicity and types of insurance were examined.

METHODS

Trend analyses were conducted with the California Health Interview Surveys among those ages 12-17 for the period 2003-2009.

RESULTS

Race/Ethnicity: Receipt of both counseling methods declined from 2003-2009 for all racial/ethnic groups, except Hispanics and Whites, for whom increases in counseling began after 2007. Hispanics and African Americans generally reported higher levels of nutrition than exercise counseling, while Whites generally reported higher levels of exercise than nutrition counseling for the study period. INSURANCE TYPE: Receipt of both counseling methods appeared to decline from 2003-2009 among all insurance types, although after 2007, a slight increase was observed for the low-cost/free insurance group. Those with private health insurance generally received more exercise counseling than nutrition counseling over the study period.

CONCLUSIONS

Counseling among all racial/ethnic groups and insurance types is warranted, but particularly needed for African Americans, American Indian/Alaska Natives, and the uninsured as they are at highest risk for developing obesity. Institutional and policy changes in the health care environment will be beneficial in helping to promote obesity-related counseling.

Racial disparities in medical expenditures within body weight categories

BACKGROUND

Despite federal guidelines calling for the reduction of obesity and elimination of health disparities, black-white differences in obesity prevalence and in medical expenditures and utilization of health care services persist.

OBJECTIVES

To examine black-white differences in medical expenditures and utilization of health care services (office-based visits, hospital outpatient visits, ER visits, inpatient stays and prescription medication) within body weight categories.

STUDY DESIGN

This study used data from the 2006 Medical Expenditures Panel Survey (MEPS) and included 15,164 non-Hispanic white and non-Hispanic black adults. We used a standard two-part econometric model to examine black-white differences in how expenditures (total annual medical expenditures and expenditures for each type of service) vary within body weight categories.

KEY RESULTS

Blacks in each weight category were less likely to use any medical care than their white counterparts, even after controlling for socio-demographic characteristics, perceived health status, health conditions and health beliefs. Among those who received medical care, there is no significant difference in the total amount spent on care between blacks and whites. Compared to whites, blacks in each body weight category were significantly less likely to use office-based visits, hospital outpatient visits, and medications. Among those who used medications, blacks had significantly lower expenditures than whites. Blacks in obese class II/III were significantly less likely to have any medical expenditures on inpatient care than their white counterparts.

CONCLUSIONS

Black-white racial differences in total medical expenditures were observed in each body weight category and were significantly different in the obese I class, overweight, and healthy weight categories. Obese blacks also spent a smaller amount than obese whites--the insignificance might be due to the smaller sample size. These differences cannot be fully explained by socio-demographics, health conditions, or health beliefs. Black-white differences in medical expenditures may be largely due to relatively inexpensive types of care (office-based visits, outpatient care, medication) rather than more costly ones (inpatient care, ER).

Weight gain prevention among black women in the rural community health center setting: the Shape Program

BACKGROUND

Nearly 60% of black women are obese. Despite their increased risk of obesity and associated chronic diseases, black women have been underrepresented in clinical trials of weight loss interventions, particularly those conducted in the primary care setting. Further, existing obesity treatments are less effective for this population. The promotion of weight maintenance can be achieved at lower treatment intensity than can weight loss and holds promise in reducing obesity-associated chronic disease risk. Weight gain prevention may also be more consistent with the obesity-related sociocultural perspectives of black women than are traditional weight loss approaches.

METHODS/DESIGN

We conducted an 18-month randomized controlled trial (the Shape Program) of a weight gain prevention intervention for overweight black female patients in the primary care setting. Participants include 194 premenopausal black women aged 25 to 44 years with a BMI of 25-34.9 kg/m2. Participants were randomized either to usual care or to a 12-month intervention that consisted of: tailored obesogenic behavior change goals, self-monitoring via interactive voice response phone calls, tailored skills training materials, 12 counseling calls with a registered dietitian and a 12-month YMCA membership.Participants are followed over 18 months, with study visits at baseline, 6-, 12- and 18-months. Anthropometric data, blood pressure, fasting lipids, fasting glucose, and self-administered surveys are collected at each visit. Accelerometer data is collected at baseline and 12-months.At baseline, participants were an average of 35.4 years old with a mean body mass index of 30.2 kg/m2. Participants were mostly employed and low-income. Almost half of the sample reported a diagnosis of hypertension or prehypertension and 12% reported a diagnosis of diabetes or prediabetes. Almost one-third of participants smoked and over 20% scored above the clinical threshold for depression.

DISCUSSION

The Shape Program utilizes an innovative intervention approach to lower the risk of obesity and obesity-associated chronic disease among black women in the primary care setting. The intervention was informed by behavior change theory and aims to prevent weight gain using inexpensive mobile technologies and existing health center resources. Baseline characteristics reflect a socioeconomically disadvantaged, high-risk population sample in need of evidence-based treatment strategies.

TRIAL REGISTRATION

The trial is registered with clinicaltrials.gov NCT00938535.

Application of the nonlinear Blinder-Oaxaca decomposition to study racial/ethnic disparities in antiobesity medication use in the United States

BACKGROUND

The nonlinear Blinder-Oaxaca (BO) decomposition method is gaining popularity in health services research because of its ability to explain disparity issues. The present study demonstrates the use of this method for categorical variables by addressing antiobesity medication use disparity.

OBJECTIVE

To examine racial/ethnic disparity in antiobesity medication use and to quantify the observed factor contribution behind the disparity using the nonlinear BO decomposition.

METHODS

Medical Expenditure Panel Survey data, 2002-2007, were used in this retrospective cross-sectional study. Adults with body mass index (BMI) >30, or BMI ≥27 and comorbidities such as hypertension, cardiovascular diseases, diabetes, or hyperlipidemia were included in the cohort (N=65,886,625). Multivariable logistic regression was performed to examine racial/ethnic disparity in antiobesity medication use controlling for predisposing, enabling, and need factors. The nonlinear BO decomposition was used to identify the contribution of each predisposing, enabling, and need factors in explaining the racial/ethnic disparity and to estimate the residual unexplained disparity.

RESULTS

Non-Hispanic Blacks were 46% (odds ratio [OR]: 0.54; 95% confidence interval [CI]: 0.35-0.83) less likely to use antiobesity drugs compared with non-Hispanic Whites, whereas no difference was observed between Hispanics and non-Hispanic Whites. A 0.22 percentage point of disparity existed between non-Hispanic Whites and Blacks. The nonlinear BO decomposition estimated a decomposition coefficient of -0.0013 indicating that the observed disparity would have been 58% higher (-0.0013/0.0022) if non-Hispanic Blacks had similar observed characteristics as non-Hispanic Whites. Age, gender, marital status, region, and BMI were significant factors in the decomposition model; only marital status explained the racial/ethnic disparity among all observed characteristics.

CONCLUSIONS

The study revealed that differences in the predisposing, enabling, and need characteristics (except marital status) did not successfully explain the racial/ethnic disparity in antiobesity medication use. Further studies examining racial/ethnic differences in individual beliefs, behavioral patterns, and provider prescription patterns are vital to understand these disparities.

Impact of physician BMI on obesity care and beliefs

Using a national cross-sectional survey of 500 primary care physicians conducted between 9 February and 1 March 2011, the objective of this study was to assess the impact of physician BMI on obesity care, physician self-efficacy, perceptions of role-modeling weight-related health behaviors, and perceptions of patient trust in weight loss advice. We found that physicians with normal BMI were more likely to engage their obese patients in weight loss discussions as compared to overweight/obese physicians (30% vs. 18%, P = 0.010). Physicians with normal BMI had greater confidence in their ability to provide diet (53% vs. 37%, P = 0.002) and exercise counseling (56% vs. 38%, P = 0.001) to their obese patients. A higher percentage of normal BMI physicians believed that overweight/obese patients would be less likely to trust weight loss advice from overweight/obese doctors (80% vs. 69%, P = 0.02). Physicians in the normal BMI category were more likely to believe that physicians should model healthy weight-related behaviors-maintaining a healthy weight (72% vs. 56%, P = 0.002) and exercising regularly (73% vs. 57%, P = 0.001). The probability of a physician recording an obesity diagnosis (93% vs. 7%, P < 0.001) or initiating a weight loss conversation (89% vs. 11%, P ≤ 0.001) with their obese patients was higher when the physicians' perception of the patients' body weight met or exceeded their own personal body weight. These results suggest that more normal weight physicians provided recommended obesity care to their patients and felt confident doing so.

Disparities in counseling for lifestyle modification among obese adults: insights from the Dallas Heart Study

Clinician counseling is a catalyst for lifestyle modification in obesity. Unfortunately, clinicians do not appropriately counsel all obese patients about lifestyle modification. The extent of disparities in clinician counseling is not well understood. Obese participants (BMI ≥30 kg/m(2), N = 2097) in the Dallas Heart Study (DHS), a probability-based sample of Dallas County residents ages 18-65, were surveyed regarding health-care utilization and lifestyle counseling over the year prior to DHS enrollment. Health-care utilization and counseling were compared between obese participants across three categories based on the presence of 0, 1, or 2+ of the following cardiovascular (CV) risk factors: hypertension, hypercholesterolemia, or diabetes. Logistic regression modeling was used to determine likelihood of counseling in those with 0 vs. 1+ CV risk factors, stratified by race, adjusting for age, sex, insurance status, and education. Among obese subjects who sought medical care, those with 0 CV risk factors, compared to those with 1 or 2+ CV risk factors, were less likely to report counseling about losing weight (41% vs. 67% vs. 87%, P trend <0.001), dietary changes (44% vs. 71% vs. 85%, P trend <0.001), and physical activity (46% vs. 71% vs. 86%, P trend <0.001). Blacks and Hispanics without CV risk factors had a lower odds of receiving counseling than whites without risk factors on weight loss (adjusted odds ratio (OR), 95% confidence interval (CI) for nonwhites 0.19, [0.13-0.28], whites 0.48, [0.26-0.87]); dietary changes (nonwhites 0.19, [0.13-0.27], whites 0.37, [0.21-0.64]); and physical activity (nonwhites 0.22, [0.16-0.32], whites 0.32, [0.18-0.57]). Lifestyle counseling rates by clinicians are suboptimal among obese patients without CV risk factors, especially blacks and Hispanics. Systematic education about and application of lifestyle interventions could capitalize on opportunities for primary CV risk prevention.

Obesity treatment for socioeconomically disadvantaged patients in primary care practice

BACKGROUND

Few evidence-based weight loss treatment options exist for medically vulnerable patients in the primary care setting.

METHODS

We conducted a 2-arm, 24-month randomized effectiveness trial in 3 Boston community health centers (from February 1, 2008, through May 2, 2011). Participants were 365 obese patients receiving hypertension treatment (71.2% black, 13.1% Hispanic, 68.5% female, and 32.9% with less than a high school educational level). We randomized participants to usual care or a behavioral intervention that promoted weight loss and hypertension self-management using eHealth components. The intervention included tailored behavior change goals, self-monitoring, and skills training, available via a website or interactive voice response; 18 telephone counseling calls; primary care provider endorsement; 12 optional group support sessions; and links with community resources.

RESULTS

At 24 months, weight change in the intervention group compared with that in the usual care group was -1.03 kg (95% CI, -2.03 to -0.03 kg). Twenty-four-month change in body mass index (calculated as weight in kilograms divided by height in meters squared) in the intervention group compared with that in the usual care group was -0.38 (95% CI, -0.75 to -0.004). Intervention participants had larger mean weight losses during the 24 months compared with that in the usual care group (area under the receiver operating characteristic curve, -1.07 kg; 95% CI, -1.94 to -0.22). Mean systolic blood pressure was not significantly lower in the intervention arm compared with the usual care arm.

CONCLUSION

The intervention produced modest weight losses, improved blood pressure control, and slowed systolic blood pressure increases in this high-risk, socioeconomically disadvantaged patient population. Trial Registration  clinicaltrials.gov Identifier: NCT00661817.

Impact of patient-doctor race concordance on rates of weight-related counseling in visits by black and white obese individuals

The objective of this study was to assess the impact of patient-provider race concordance on weight-related counseling among visits by obese patients. We hypothesized that race concordance would be positively associated with weight-related counseling. We used clinical encounter data obtained from the 2005-2007 National Ambulatory Medical Care Surveys (NAMCS). The sample size included 2,231 visits of black and white obese individuals (ages 20 and older) to their black and white physicians from the specialties of general/family practice and general internal medicine. Three outcome measures of weight-related counseling were explored: weight reduction, diet/nutrition, and exercise. Logistic regression was used to model the outcome variables of interest. Wald tests were used to statistically compare whether physicians of each race provided counseling at different rates for obese patients of different races. We did not observe a positive association between patient-physician race concordance and weight-related counseling. We found that visits by black obese patients to white doctors had a lower odds of exercise counseling as compared to visits by white obese patients to white doctors (odds ratio (OR) = 0.54; 95% confidence interval (CI): 0.31, 0.95), and visits by black obese patients to black physicians had lower odds of receiving weight-reduction counseling than visits among white obese patients seeing black physicians (OR = 0.34; 95% CI: 0.13, 0.90). Black obese patients receive less exercise counseling than white obese patients in visits to white physicians and may be less likely than white obese patients to receive weight-reduction counseling in visits to black physicians.

Obesity, stigma, and responsibility in health care: A synthesis of qualitative studies

Objective

To synthesize research findings on experiences and attitudes about obesity and stigma in health care.

Methods

We compiled qualitative studies and applied Noblitt & Hare's meta ethnography to identify, translate, and summarize across studies. Thirteen qualitative studies on experiences and attitudes about obesity and stigma in health care settings were identified and included.

Results

The study reveals how stigmatizing attitudes are enacted by health care providers and perceived by patients with obesity. Second-order analysis demonstrated that apparently appropriate advice can be perceived as patronizing by patients with obesity. Furthermore, health care providers indicate that abnormal bodies cannot be incorporated in the medical systems—exclusion of patients with obesity consequently happens. Finally, customary standards for interpersonal respect are legitimately surpassed, and patients with obesity experience contempt as if deserved. Third-order analysis revealed conflicting views between providers and patients with obesity on responsibility, whereas internalized stigma made patients vulnerable for accepting a negative attribution. A theoretical elaboration relates the issues of stigma with those of responsibility.

Conclusion

Contradictory views on patients’ responsibility, efforts, knowledge, and motivation merge to internalization of stigma, thereby obstructing healthy coping and collaboration and creating negative contexts for empowerment, self-efficacy, and weight management. Professionals need to develop their awareness for potentially stigmatizing attitudes towards vulnerable patient populations.

Primary care physician attitudes and practice patterns in the management of obese adults: results from a national survey

PURPOSE

Obesity remains a serious public health problem. The purpose of this study was to identify the current attitudes and practices of primary care physicians (PCPs) with respect to obesity.

METHODS

A survey was systematically developed and administered electronically to PCPs, who received a small honorarium for their time. Results were analyzed to identify specific attitudes and practices and their associations with each other and with demographic and other variables.

RESULTS

Physicians expressed little confidence in their ability to manage obesity. In general, however, they believed that obesity could be successfully managed. Lifestyle changes were perceived to be the most effective available method for patients to lose weight, and respondents were more likely to recommend this approach over pharmacotherapy or bariatric surgery. Respondents perceive the greatest barrier to managing obese patients to be a lack of patient motivation. Physicians were significantly more likely to initiate discussions with obese patients about their weight if they believed they had positive attitudes about and knowledge of weight management, and adequate resources to manage the problem.

CONCLUSIONS

Physicians report a lack of confidence in managing obesity. Lack of patient motivation is perceived to be the greatest barrier. Physicians with greater knowledge, more positive attitudes toward obesity management, and access to more resources are more likely to provide weight management in primary care settings.

Patient-physician gender concordance and weight-related counseling of obese patients

BACKGROUND

Obesity affects approximately one third of Americans. Patient and provider characteristics such as gender may influence obesity care. Gender concordance has been associated with clinical practice patterns in chronic conditions such as hypertension and diabetes, but its role in obesity care is unknown.

PURPOSE

The purpose of this study was to investigate the association of patient-physician gender concordance with weight-related counseling among obese adults.

METHODS

A cross-sectional study using the 2005-2007 National Ambulatory Medical Care Survey was conducted in 2010. Postvisit data from the clinical encounters of 5667 obese individuals and their physicians were analyzed to determine the association between patient-physician gender concordance (categorized using patient gender as the reference point as female gender-concordant, male gender-concordant, male gender-discordant, and female gender-discordant) and three types of weight-related counseling (diet/nutrition, exercise, and weight reduction).

RESULTS

Diet/nutrition, exercise, and weight reduction counseling was provided to 30%, 23%, and 20% of obese patients, respectively. Patients in male gender-concordant patient-physician pairs had significantly higher adjusted odds of receiving diet/nutrition (OR=1.58, 95% CI=1.05, 2.40) and exercise counseling (OR=1.76, 95% CI=1.13, 2.74) than female gender-concordant pairs. There were no significant differences in any form of weight-related counseling between female gender-concordant and gender-discordant pairs.

CONCLUSIONS

The findings of this study suggest that male patient-physician gender concordance is positively associated with diet/nutrition and exercise counseling.

Variation in Provider Identification of Obesity by Individual- and Neighborhood-Level Characteristics among an Insured Population

Objective. The purpose of this study was to examine whether neighborhood- and individual-level characteristics affect providers' likelihood of providing an obesity diagnosis code in their obese patients' claims. Methods. Logistic regressions were performed with obesity diagnosis code serving as the outcome variable and neighborhood characteristics and member characteristics serving as the independent variables (N = 16,151 obese plan members). Results. Only 7.7 percent of obese plan members had an obesity diagnosis code listed in their claims. Members living in neighborhoods with the largest proportions of Blacks were 29 percent less likely to receive an obesity diagnosis (P < .05). The odds of having an obesity diagnosis code were greater among members who were female, aged 44 or below, hypertensive, dyslipidemic, BMI >/= 35 kg/m(2), had a larger number of provider visits, or who lived in an urban area (all P < .05). Conclusions. Most health care providers do not include an obesity diagnosis code in their obese patients' claims. Rates of obesity identification were strongly related to individual characteristics and somewhat associated with neighborhood characteristics.
