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

Women's perceptions of body mass graphics and their preferences for weight counselling

Health care providers may lack data-driven guidance about best practises for discussing weight. We assessed women's self-perception of body mass index (BMI) and preferences for weight counselling by provider characteristics and the initiating question. A voluntary, anonymous survey was completed by 756 women (age ≥ 19 year) at our tertiary care obstetrics and gynaecology clinics in autumn 2021. The respondents' height and weight were collected before respondents selected graphics from a validated Body Image Scale that they felt best represented their current body size and which graphs should prompt weight loss or gain recommendations. Respondents were asked their preferences about provider characteristics for discussion about weight and to identify which of six initiating questions from a provider was most and least preferred. Blank responses were allowed. In 708 responses, 366 women (52%) selected the most accurate graphic that corresponded to their BMI; the selected graphic represented a lower than actual BMI in 268 women (38%) and higher in 74 women (10%). In 648 responses, 374 women (58%) preferred a female provider, but provider body shape, ethnicity/race and age were not important to most women. The most preferred question to initiate a discussion about weight was "A lot of women have trouble achieving or maintaining a healthy weight; is that something we can discuss?" in 181 of 555 women (33%), and the least preferred question was "Do you feel like you are at an appropriate weight?" in 172 of 554 women (31%). Provider knowledge about patient preferences regarding questions may facilitate the discussion about weight.

Association of race and receipt of regional anesthesia for hip fracture surgery

BACKGROUND

There is evidence suggesting clinical benefits of regional anesthesia use in the setting of hip fracture repair, including reduced risk of death, deep vein thrombosis, pulmonary complications and myocardial infarction. Thought the literature is mixed, the use of regional anesthesia in hip fracture surgery has not been studied for racial differences. We examined the association of race with neuraxial anesthesia and regional blocks in patients undergoing hip fracture surgery.

METHODS

Using American College of Surgeons National Surgical Quality Improvement Program, we identified patients ≥18 years old who were either white, black or Asian and underwent hip fracture surgery from 2014 to 2020. We reported unadjusted estimates of both regional and neuraxial anesthesia use by race and examined sociodemographic characteristics and health status differences. Two separate multivariable logistic regression models were employed to investigate the association of race with the receipt of (1) neuraxial anesthesia and (2) regional block (ie, peripheral nerve blocks, fascial plane blocks).

RESULTS

There were 104,949 patients who underwent hip fracture surgery, of whom 16,400 (15.6%) received a neuraxial anesthetic and 6264 (5.9%) received a regional block. On multivariable logistic regression analysis, compared with white patients, black patients (OR 0.67, 99% CI 0.59 to 0.75, p<0.001) had decreased odds, while Asian patients (OR 2.04, 99% CI 1.84 to 2.26, p<0.001) had increased odds for receipt of neuraxial anesthesia as a primary anesthetic. Black race (OR 1.35, 99% CI 1.17 to 1.55, p<0.001) was associated with increased odds for receiving a regional block compared with white patients.

CONCLUSIONS

The study suggests that racial differences exist with the utilization of regional anesthesia for hip fracture surgery. While the results of this study should not be taken as evidence for healthcare disparities, it could be used to support hypotheses for future studies that aim to investigate causes of disparities and corresponding patient outcomes.

A Call to Reconceptualize Obesity Treatment in Service of Health Equity: Review of Evidence and Future Directions

PURPOSE OF REVIEW

Rates of obesity and associated comorbidities are higher among Black and Latino adults compared to white adults. We sought to provide an overview of both structural and individual factors contributing to obesity inequities and synthesize available evidence regarding treatment outcomes in Black and Latino adults, with an eye towards informing future directions.

RECENT FINDINGS

Obesity disparities are influenced by myriad systemic issues, yet the vast majority of interventions target individual-level factors only, and most behavioral treatments fail to target drivers beyond eating and physical activity. Extant treatments are not equally accessible, affordable, or effective among Black and Latino adults compared with white counterparts. Asset-based, culturally relevant interventions that target the root causes of obesity and address intersectional stress-designed in partnership with intended beneficiaries-are urgently needed. Treatment trials must improve enrollment of Black and Latino adults and report treatment outcomes by race and ethnicity.

Person-centered communication about weight and weight management: Focus group discussions in a diverse sample of women with nonmetastatic breast cancer and obesity

BACKGROUND

Women with obesity are at higher risk for high-grade and/or advanced-stage breast cancer in comparison with women without obesity. Many women with a high body mass index (BMI) at breast cancer diagnosis experience further weight gain during and after treatment. This study investigated Black and White patient perspectives on conversations with their oncologists about weight and weight management.

METHODS

Focus groups using a virtual platform (Zoom) were conducted with women after primary treatment for stage I to III breast cancer who were 21 years or older and had a BMI ≥ 30 kg/m² : 2 with Black women (n = 12) and 2 with White women (n = 14).

RESULTS

Participants asked that their oncologists be "transparent" about weight gain as a potential side effect of their cancer treatment and how excess weight might affect their prognosis and survival. They asked to be "seen as an individual" to facilitate both person-centered and culturally appropriate conversations about behavioral changes needed for weight management. Participants urged clinicians to take the lead in initiating conversations about weight to underscore its importance in cancer care and survivorship. They welcomed actionable recommendations about nutrition and exercise from either the oncology clinician or a specialist. Participants offered specific suggestions on how clinicians could initiate weight-related conversations, beginning with questions eliciting patients' perspectives on their weight and lifestyle.

CONCLUSIONS

Many women with early-stage breast cancer and obesity have concerns about weight and weight gain and urge their oncologists to use an active and personalized approach in recommending and supporting efforts at weight management.

LAY SUMMARY

Focus group discussions with Black and White women with early-stage breast cancer and obesity have elicited patient perspectives on conversations with their oncologists about weight and weight management. Many patients have concerns about weight and weight gain and urge their oncologists to use an active and personalized approach in recommending and supporting efforts at weight management.

Physical Activity Health Communication for Adults With Mood Disorders in the United States

Using national representative data, this study sought to examine receipt of physical activity communication and counseling among adults with mood disorders in comparison to the general population in the United States. The sample consisted of adult primary-care visits in the National Hospital Ambulatory Medical Care and National Ambulatory Medical Care Surveys. Multivariable logistic regression was used to examine the relationship between mental health status and receipt of physical activity communication and counseling. Overall, less than 20% of visits included physical activity communication and counseling. Controlling for covariates, visits for adults with a mood disorder diagnosis were associated with an increased odds of including physical activity communication and counseling, odds ratio = 1.25, 95% confidence interval = [1.08, 1.45]. Although adults with mood disorders were more likely to receive physical activity communication and counseling, most primary-care visits for adults in the United States did not include physical activity communication and counseling.

Factors influencing U.S. physicians' decision to provide behavioral counseling

Prevention and treatment of non-communicable diseases is critical due to high costs of healthcare and increasing prevalence. Historical trends suggest physicians underperform in behavioral counseling (including exercise, diet/nutrition, or weight management). This study investigated physicians' decision-making by examining non-clinical sociological factors that influence ordering and provision of behavioral counseling. This was a retrospective multi-year cross-sectional study. Using the Eisenberg model of physician-decision making, we analyzed data from the 2005-2015 National Ambulatory Medical Care Surveys (unweighted N = 177,599). Four weighted logistic regressions were performed to examine sociological factors associated with physician prescribing or ordering of behavioral counseling. Behavioral counseling was provided at suboptimal rates. Patient age, race/ethnicity, body weight status, and reasons for a medical visit were associated with physicians' decision to provide or order behavioral counseling. There was in general a decreasing trend of odds of provision of behavior counseling from 2005 to 2015. Patients who had been seen before were more likely to receive diet/nutrition and exercise counseling. This study concluded that ordering and provision of behavioral counseling was less than optimal. Policy makers and educators can consider factors that influence physicians' decisions for behavioral counseling to improve training and site policies. Future research examining effective behavioral counseling training and strategies to promote its provision, in particular to patients of different races/ethnicities and with different medical conditions, may increase effectiveness. Integrated care with behavioral health professionals could improve rates and/or delivery of counseling. Physicians can consider providing behavioral counseling when patients present with new problems and to newly seen patients.

Impact of weight-related advice from healthcare professionals on body mass index of patients in the USA

OBJECTIVES

Healthcare professionals (HCPs) can help promote healthy eating and active living in patients. This study assessed the effects of weight-related advice from HCPs on change in body mass index (BMI) of patients in the USA.

STUDY DESIGN

A 1-year follow-up study of 20,002 adults who participated in a nationally representative survey between 2004 and 2008.

METHODS

Using the 2004-2008 Medical Expenditure Panel Survey data, 1-year BMI and weight status changes were compared between patients who did and did not report receiving advice on exercise or on restricted intake of fat and cholesterol from their HCPs.

RESULTS

Patients who received weight-related advice had a greater increase in BMI compared with those who did not receive weight-related advice. Stratified by the baseline weight status of patients (i.e. normal weight, overweight or obese), adverse direction of BMI change was only significantly associated with advice on exercise. Patients who received advice to exercise more were more likely to move to a higher weight status than remaining at the same weight status, compared with patients who did not receive advice to exercise more.

CONCLUSION

This study did not find that weight-related advice from HCPs had a positive impact on BMI loss in patients. On the contrary, patients who reported receiving weight-related advice from HCPs had worse weight outcomes 1 year later than patients who did not report receiving weight-related advice. Further research is warranted to elucidate the role of weight-related advice from HCPs on lifestyle change and obesity prevention and control.

Physicians' views and experiences of discussing weight management within routine clinical consultations: A thematic synthesis

OBJECTIVE

To systematically search and synthesise qualitative studies of physicians' views and experiences of discussing weight management within a routine consultation.

METHODS

A systematic search of four electronic databases identified 11,169 articles of which 16 studies met inclusion criteria. Quality was appraised using the Critical Appraisal Skills Programme tool and a thematic synthesis conducted of extracted data.

RESULTS

Four analytical themes were found: (1) physicians' pessimism about patients' weight loss success (2) physicians' feel hopeless and frustrated (3) the dual nature of the physician-patient relationship (4) who should take responsibility for weight management.

CONCLUSION

Despite clinical recommendations barriers remain during consultations between physicians and patients about weight management. Many of these barriers are potentially modifiable.

PRACTICE IMPLICATIONS

Improving training, providing clearer guidelines and placing a greater emphasis on collaboration within and between clinicians will help reduce barriers for both physicians and patients. In particular, there is an urgent need for more specialised training for physicians about weight management to promote knowledge and skills in behaviour change techniques and ways to broach sensitive topics without damaging patient relationships.

The Lifestyle Intervention for the Treatment of Diabetes study (LIFT Diabetes): Design and baseline characteristics for a randomized translational trial to improve control of cardiovascular disease risk factors

The prevalence of type 2 diabetes continues to increase in minority and underserved patients, who are also more likely to have poorer control of diabetes and related risk factors for complications. Although the Look AHEAD trial has demonstrated improved risk factor control among overweight or obese diabetes patients who received an intensive lifestyle intervention, translating such findings into accessible programs is a major public health challenge. The purpose of this paper is to report the design and baseline characteristics of the Lifestyle Interventions for the Treatment of Diabetes study (LIFT Diabetes). The overall goal is to test the impact of a community-based lifestyle weight loss (LWL) intervention adapted from Look AHEAD on cardiovascular disease risk at 12-months and 24-months among minority and lower income diabetes patients. Secondary outcomes include body weight, physical activity, medication use, cost, resource utilization, and safety. The primary hypothesis being tested is that the LWL will result in 10% relative reduction in CVD risk compared to the DSM. We have randomized 260 overweight or obese adults with diabetes one of two 12-month interventions: a LWL condition delivered by community health workers or a diabetes self-management (DSM) education condition. The baseline demographic characteristics indicate that our sample is predominantly female, obese, low income, and ethnic minority. Translating evidence-based, lifestyle strategies, and targeting minority and underserved patients, will yield, if successful, a model for addressing the burden of diabetes and may favorably impact health disparities.

Strong, female and Black: Stereotypes of African Caribbean women’s body shape and their effects on clinical encounters

The aim of this article is to explore how tendencies to stereotype minority ethnic groups intersect with lay discourses about them in ways that can reproduce cultural prejudices and reinforce inequalities in access to services and health outcomes. Drawing upon Black feminist and cultural studies literature, we present a theoretical examination, the stereotypes of the Black woman as ‘mammy’ and ‘matriarch’. We suggest that the influence of these two images is central to understanding the normalisation of the larger Black female body within African Caribbean communities. This representation of excess weight contradicts mainstream negative discourses of large bodies that view it as a form of moral weakness. Seeking to stimulate reflection on how unacknowledged stereotypes may shape clinical encounters, we propose that for Black women, it is the perception of strength, tied into these racial images of ‘mammy’ and ‘matriarch’ which may influence when or how health services or advice are both sought by them and offered to them. This has particular significance in relation to how body weight and weight management are/are not talked about in primary care-based interactions and what support Black women are/are not offered. We argue that unintentional bias can have tangible impacts and health outcomes for Black women and possibly other minority ethnic groups.

Racial and ethnic minority patients report different weight-related care experiences than non-Hispanic Whites

Our objective was to compare patients' health care experiences, related to their weight, across racial and ethnic groups. In Summer 2015, we distributed a written survey with telephone follow-up to a random sample of 5400 racially/ethnically and geographically diverse U.S. adult health plan members with overweight or obesity. The survey assessed members' perceptions of their weight-related healthcare experiences, including their perception of their primary care provider, and the type of weight management services they had been offered, or were interested in. We used multivariable multinomial logistic regression to examine the relationship between race/ethnicity and responses to questions about care experience. Overall, 2811 members (53%) responded to the survey and we included 2725 with complete data in the analysis. Mean age was 52.7 years (SD 15.0), with 61.7% female and 48.3% from minority racial/ethnic groups. Mean BMI was 37.1 kg/m² (SD 8.0). Most (68.2%) respondents reported having previous discussions of weight with their provider, but interest in such counseling varied by race/ethnicity. Non-Hispanic blacks were significantly less likely to frequently avoid care (for fear of discussing weight/being weighed) than whites (OR 0.49, 95% CI 0.26–0.90). Relative to whites, respondents of other race/ethnicities were more likely to want weight-related discussions with their providers. Race/ethnicity correlates with patients' perception of discussions of weight in healthcare encounters. Clinicians should capitalize on opportunities to discuss weight loss with high-risk minority patients who may desire these conversations.

•

Minority patients may desire more information about weight management.

•

Non-Hispanic whites may be more likely to avoid care due to fear of weight bias.

•

Clinicians could conduct more sensitive weight loss discussions with all patients.

Disparities in Treatment Uptake and Outcomes of Patients with Obesity in the USA

There are clear and persistent disparities in obesity prevalence within the USA. Some of these disparities fall along racial/ethnic lines; however, there are a number of other social and demographic constructs where obesity disparities are present. In addition to differing rates of obesity across groups, there is growing evidence that subgroups of patients both seek out and respond to obesity treatment differently. This review article explores the epidemiology of obesity disparities, as well as the existing evidence around how different groups may respond to behavioral, medical, and surgical therapies, and potential reasons for differential uptake and response, from culture, to access, to physiology. We find that the vast majority of evidence in this area has focused on the observation that African Americans tend to lose less weight in clinical trials compared to non-Hispanic whites and mainly pertains to behavioral interventions. Moving forward, there will be a need for studies that broaden the notion of health disparity beyond just comparing African Americans and non-Hispanic whites. Additionally, a more thorough examination of the potential for disparate outcomes after medical and surgical treatments of obesity is needed, coupled with the careful study of possible physiologic drivers of differential treatment response.

Patient-health care professional gender or race/ethnicity concordance and its association with weight-related advice in the United States

OBJECTIVE

Examine association between adult patients' and health care providers' (HCPs) gender or race/ethnicity concordance and patients' reported receiving weight-related advice from HCP's in USA.

METHODS

Using Medical Expenditure Panel Survey (MEPS) 2004-2007 data, studied prevalence of weight-related advice (on exercise and diet) given to patients and its association with patients/HCPs concordance in gender (n=9,686) and race/ethnicity (n=8,825).

RESULTS

Overall, 46% of patients received HCP advice on diet and 49% on exercise. Overweight females seeing female HCPs were more likely to receive exercise advice than those seeing male HCPs (OR=1.44 [95% CI: 1.10-1.89]). Race/ethnicity concordance was associated with lower odds of advice-receiving in certain populations (OR=0.80 [0.67-0.97] for exercise and OR=0.42 [0.19-0.91] for diet among white patients, OR=0.47 [0.23-0.98] for exercise among Hispanic overweight patients).

CONCLUSIONS

Patient/HCP gender or race/ethnicity concordance was not positively associated with HCPs providing weight-related advice. Patients with female HCPs or with racial/ethnic discordant HCPs (especially black or Asian HCPs) were more likely to receive advice.

PRACTICE IMPLICATIONS

Health care providers need be empowered, particularly white and male HCPs, to improve delivery of weight-related advice. It may reflect better of receiving weight-related advice based on patients' recall.

Enhancing the role of nutrition professionals in weight management: A cross-sectional survey

OBJECTIVE

(1) To determine the nonphysician health profession perceived as best qualified to provide weight management. (2) To examine nutrition professionals' current practice characteristics and perceived challenges and solutions for obesity care. (3) To examine the association between nutrition professionals' quality of training and self-efficacy in weight management.

METHODS

A 2014 national cross-sectional online survey of 500 U.S. nonphysician health professionals (100 from each: nutrition, nursing, behavioral/mental health, exercise, pharmacy) was analyzed.

RESULTS

Nutrition professionals most commonly self-identified as the most qualified group to help patients lose weight (92%), sentiments supported by other health professionals (57%). The most often cited challenge was lack of patient adherence (87%). Among nutrition professionals, 77% reported receiving high-quality training in weight loss counseling. Nutrition professionals who reported high-quality training were significantly more likely to report confidence (95% vs. 48%) and success (74 vs. 50%) in helping obese patients lose weight (P<0.05) than those reporting lower-quality training.

CONCLUSIONS

Across all nonphysician health professionals, nutrition professionals were identified as best suited to provide routine weight management counseling to obese patients. Yet nutrition professionals' receipt of high-quality weight management training appears critical to their success in helping patients lose weight.

The impact of physician weight discussion on weight loss in US adults

PROBLEM

The increasing prevalence of overweight and obesity in the United States and worldwide is at epidemic levels. Physicians may play a vital role in addressing this epidemic. We aimed to examine the association of a physician's discussion of patients’ weight status with self-reported weight loss. We hypothesized that physician discussion of patients’ being overweight is associated with increased weight loss in patients with overweight and obesity.

METHODS

Data analysis of participants (n = 5054) in the National Health and Nutritional Examination Survey (NHANES) in 2005-2008. The main outcome was rates of self-reported weight loss and the association with physicians’ discussion of their patients’ weight status.

RESULTS

Overweight and obese participants were significantly more likely to report a 5% weight loss in the past year if their doctor had told them they were overweight (adjusted OR (AOR) 1.88; 95% CI 1.45-2.44; AOR 1.79; 95% CI 1.30-2.46, respectively).

CONCLUSIONS

Physicians’ direct discussion of their patients’ weight status is associated with clinically significant patient weight loss and may be a targetable intervention. Further studies are needed to determine if increasing physician discussion of patients’ weight status leads to significant weight loss.

Impact of patient and navigator race and language concordance on care after cancer screening abnormalities

BACKGROUND

Patient navigation improves the timely diagnosis of cancer among minorities, but little is known about the effects of patient and navigator race and language concordance on health outcomes.

METHODS

The authors investigated the effects of patient and navigator race and language concordance on the time to diagnosis of cancer screening abnormalities among participants in the Boston Patient Navigation Research Program, a clinical effectiveness trial for women who had breast or cervical cancer screening abnormalities identified from January 1, 2007 to December 31, 2008. Hazard ratios and 95% confidence intervals were estimated using proportional hazards regression adjusting for clinical and demographic factors.

RESULTS

In total, 1257 women had breast cancer screening abnormalities (n = 655) or cervical cancer screening abnormalities (n = 602) identified, and 56% were nonwhite. Language concordance was associated with timelier resolution for all patients in the cervical cancer screening abnormalities group during the first 90 days (adjusted hazard ratio, 1.46; 95% confidence interval, 1.18-1.80), and specifically for Spanish speakers during the first 90 days (adjusted hazard ratio, 1.43; 95% confidence interval, 1.10-1.84), but no difference was observed after 90 days for women who had cervical cancer screening abnormalities or at any time for those who had breast cancer screening abnormalities. Race concordance was associated with significant decreases in the time to diagnosis for minority women with breast and cervical cancer screening abnormalities in analyses stratified by race, but no differences were observed in analyses that included all women.

CONCLUSIONS

Patient navigator race and language concordance improved the timeliness of care in a minority population. Patient navigators who are racially/ethnically diverse and multilingual may help address barriers to care and improve cancer outcomes for low-income minorities.

The effect of rising obesity on eligibility to serve in the U.S. Public Health Service Commissioned Corps

This study investigates how rising obesity has affected eligibility to serve in the United States Public Health Service Commissioned Corps (PHSCC), the uniformed service charged with protecting and promoting public health in the U.S. Data are drawn from the National Health and Nutrition Examination Surveys. Between 1959 and 2010, the percentage of eligible civilians who exceed the weight-for-height and body fat standards of the PHSCC rose from 9.05% to 18.24% among men, and from 6.13% to 23.10% among women. Simulations indicate that a further 1% increase in population body weight will result in an additional 3.42% of men and 5.08% of women exceeding PHSCC accession standards. This study documents an under appreciated consequence of the rise in obesity: fewer Americans eligible to develop and implement a public health response to obesity through the PHSCC. This illustrates how a public health problem can undermine the public health labor force, compromising a response and risking a self-reinforcing trend. These findings are timely as the Patient Protection and Affordable Care Act (ACA) calls for a major expansion of the PHSCC.

The impact of the 2007 expert committee recommendations on childhood obesity preventive care in primary care settings in the United States

OBJECTIVES

In this study we examined the impact of the Expert Committee Recommendations (ECRs) on childhood obesity preventive care during well-child visits in the United States.

METHODS

Data from the 2006-2009 National Ambulatory Medical Care Survey and National Hospital Ambulatory Care Survey-outpatient department were used to examine frequencies of diet/nutrition and exercise counseling during well-child visits by children aged 2 to 18 years. Differences in rates of the counseling before and after the ECRs were made were compared.

RESULTS

Only 37% and 22% of all patients in 2006-2007 and 33% and 18% of all patients in 2008-2009 were provided with diet/nutrition and exercise counseling, respectively. The frequencies of counseling for patients with a diagnosis of obesity showed no change. Socioeconomically disadvantaged children received counseling less frequently after the ECRs were made.

CONCLUSION

Overall, rates of obesity preventive care were low in all years, with no evidence of improvement after the ECRs were made. Systematic approaches are needed to improve delivery of obesity preventive care irrespective of the socioeconomic backgrounds of children.

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.

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.

Obesity and Black Women: Special Considerations Related to Genesis and Therapeutic Approaches

Black women in the United States are disproportionately affected by obesity, with almost two-thirds considered obese based on body mass index. Obesity has been directly linked to cardiovascular morbidity and mortality in black women. Therefore, understanding contributors to the genesis of obesity in black women is imperative. While biologic differences likely result in varying obesity prevalence across racial/ethnic groups, behaviors such as post-partum weight retention and limited leisure-time physical activity, may especially contribute to obesity in black women. Black women also appear to be particularly susceptible to cultural, psychosocial, and environmental factors that can promote weight gain. Therapeutic interventions are being tailored to specifically address these social determinants of health and to foster lifestyle modification; however, more work is needed to understand barriers to behavior change for black women. Knowledge gaps also remain in identifying mechanisms by which pharmacologic and surgical treatments for obesity modify cardiovascular risk in black women.

Impact of participant and interventionist race concordance on weight loss outcomes

OBJECTIVE

We have previously shown that racial composition of behavioral intervention groups does not affect achieved weight loss. However, it is unclear if the race of the interventionist affects intervention outcomes. The objective of this analysis is to estimate the impact of race concordance between participant and interventionist on weight change in the initial weight loss phase (phase I) of the Weight Loss Maintenance trial (WLM).

DESIGN AND METHODS

A total of 1,685 overweight or obese adults (BMI 25-45 kg/m(2) ) who were taking medication for hypertension and/or dyslipidemia participated in phase I of the WLM trial. All participants received a 6-month intensive behavioral intervention in groups of 15-20 facilitated by a trained interventionist. The main outcome is change in weight at 6 months.

RESULTS

Participants were on average 55 years of age, 67% female and 44% African American (AA). Three of seventeen interventionists were AA, 14 were non-AA. Seventy-three percent of participants shared race concordance with the interventionist. There was a small but statistically significant difference in weight change of participants who were the same race as the interventionist (-5.84 kg, s.e. 0.17) as compared with those who were not race concordant (-5.04 kg, s.e. 0.33), a difference of 0.8 kg, (P = 0.04). The impact of concordance on weight change differed by race (i.e., interaction of race and concordance was significant, P = 0.02).

CONCLUSIONS

In a post hoc analysis of a group-based behavioral intervention, race concordance for non-AA participants was associated with slightly greater weight loss. Race concordance was not associated with weight loss for AA participants.

The epidemiology of weight counseling for adults in the United States: a case of positive deviance

Weight counseling for adults is uncommonly performed by primary-care providers (PCPs), despite recommendations. In order to design effective primary-care interventions, a full understanding of the epidemiology of weight counseling in primary care is needed. Our objective was to measure the frequency of weight counseling at the level of the PCP. We performed a cross-sectional study of 21 220 US adult outpatient primary-care visits with 954 PCPs in 2007-2008, using data from the National Ambulatory Medical Care Survey (NAMCS). Most (58%) PCPs performed no weight counseling during any patient visits. A total of 85 (8.9%) PCPs provided 52% of all weight counseling and were categorized as 'positive deviant' (PD) physicians. Patients seeing PD physicians were older, less likely to be female and more likely to have hypertension, diabetes and obesity. Adjusting for patient characteristics strengthened the association between PD status and receipt of weight counseling during visits (adjusted odds ratio=13.2 (95% confidence interval 11.5-15.7)). In conclusion, a minority of PCPs provide the majority of primary-care weight counseling in the United States. Studies of these PCPs may help to identify practical methods to increase weight counseling 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.
