Treatment Recommendations in Oncology Visits: Implications for Patient Agency and Physician Authority

ABSTRACT

Although oncology is a major site for clinician?patient treatment negotiation requiring a careful balance of potentially competing viewpoints, little is known about how clinicians promote their treatment recommendations to patients and what the manner of promotion tells us about the oncologist?patient relationship. Utilizing an already-established schema of coding treatment recommendations, I draw on 61 treatment recommendations to examine treatment decision-making in oncology. This paper investigates how physicians balance asserting their authority while at the same time attending to patient agency and involvement in decision-making. Taking this one step further, this paper explores how physicians negotiate decision-making with patients given that they occupy a liminal state between obligations to policy imperatives and commitments to their professional knowledge and technical expertise. How do they do this, and what accounts for this? To answer these questions, this paper analyzes the ways in which physicians present treatment recommendations and the treatment contexts in which they are made.     

Association between prognostic awareness and quality of life in patients with advanced cancer

Purpose

Despite the current guidelines supporting open communication about serious news, the evidence about the impact of prognostic awareness on the quality of life in cancer patients is not clear. The aim of this study was to assess the association between quality of life and prognostic awareness in patients with advanced cancer.

Methods

This was a cross-sectional study which involved patients (n?=?129) with incurable advanced cancer (estimated by oncologist using 12-month surprise question). Data were collected at oncology departments at 3 hospitals using structured interview in which patients were asked about their quality of life (using Integrated Palliative Outcome Scale—IPOS and a single-item global measure), prognostic awareness, information needs and demographics.

Results

Only 16% of the sample was completely aware of prognosis and 57% was partially aware. Accurate prognostic awareness was significantly associated (p?=?0.02) with lower level of quality of life between (when measured by both the IPOS and the single-item scale) patients with accurate prognostic awareness (M?=?37.1; 10.4) and partially aware (M?=?31.9; 9.1) and unaware patients (M?=?30; 7.4). Detailed analysis showed that significant difference between groups was found only for physical symptoms subscales (p?=?0.002), not for emotional and communication subscales.

Conclusion

Prognostic awareness was found to be negatively associated with physical domain of quality of life, but not with emotional and communication domains. More research is needed on personality factors that might influence the development of prognostic awareness and quality of life.

     

A pilot evaluation of the expanded prostate cancer index composite for clinical practice (EPIC-CP) tool in Ontario

Purpose

To introduce the EPIC-CP symptom screening tool in routine ambulatory cancer care, and to evaluate its acceptability and perceived usefulness from the perspective of patients and clinicians.

Methods

Eligible prostate cancer patients from four cancer centres were recruited (November 2014–June 2015) from radiation or surgical oncology clinics. A physician and/or health care professional reviewed the EPIC-CP results as part of the clinical encounter. Patient experience with the tool was evaluated using a nine-item Patient Exit Survey (PES). Clinician experience was evaluated through semi-structured qualitative interviews. Patient and clinician results were compared to identify common themes.

Results

A total of 333 patients were enrolled, of whom, 287 completed the PES. Most patients had one clinical encounter, although the number of EPIC-CP assessments ranged from 1 to 11 per patient, for a total of 937 EPIC-CP questionnaires completed. Item completion rates were high (91–100%), with items addressing sexual health among the lowest (91–92%). On the PES, most patients (70%) agreed with the item: “Completing this questionnaire helped me tell the clinicians about how I have been feeling”. Thematic analysis from clinician interviews revealed that the EPIC-CP captures essential prostate-specific effects that facilitated person-centred communication and customization of interventions. Targeted clinical education and patient resources were seen as necessary for uptake.

Conclusions

EPIC-CP was generally endorsed by clinicians and patients. The implementation of a disease-specific measure in place of a generic symptom screening tool has the potential to improve the quality of the clinical encounter and provide outcome measures for further health services research. Provincial implementation of this tool as a standard of care is recommended.

     

Smoking,Weight Loss Intention and Obesity-Promoting Behaviors in College Students

Objective: To examine whether college smoking was associated with trying to lose weight and other weight-related behaviors.

Methods: We surveyed 300 students at the University of Kansas about smoking (ever, current, and amount), weight loss intention (y/n), weight-related attitudes, and eating and exercise behavior. Weight, height, and body fat were measured.

Results: About half the students (49%) self-identified as having ever smoked while 53 (17.6%) self-identified as current smokers. After controlling for sex, age, and ethnicity, ever smoking was not related to weight loss intention but was associated with greater pressure to maintain a healthy weight (p = 0.05), and having engaged in mild exercise on more days in the previous year (p = 0.05). Compared to nonsmokers, current smokers ate more at restaurants serving high calorie foods (p < 0.05) and ate more frequently in front of the TV (p < 0.01). Amount smoked was related to diminished use of exercise facilities (p = 0.03) and more frequent eating at restaurants serving high calorie foods (p < 0.05) and in front of the TV (p = 0.01).

Conclusions: Current smoking among college students was related to weight loss intention. Despite wanting to lose weight, current smoking was concomitant with obesity-promoting behaviors such as eating higher calorie foods and eating in front of the TV. College-based interventions to prevent smoking initiation or promote smoking cessation should include a focus on healthy eating, exercise and healthful ways to lose or maintain weight.     

Determinants of adherence to physical activity guidelines among overweight and obese African American breast cancer survivors: implications for an intervention approach

Objective: Public health agencies encourage breast cancer survivors (BCSs) to follow their physical activity guidelines (PAGs). However, adherence to these guidelines is low. African American (AA) BCSs are more often overweight or obese and less likely than women of other races to report adherence to physical activity recommendations. This study examined socioeconomic, clinical, and psychosocial correlates with meeting PAGs.

Design: AA women diagnosed and treated for breast cancer and participating in a breast cancer support group (N?=?193) completed a lifestyle assessment tool capturing demographic characteristics; breast cancer diagnosis and treatment history; health-related quality of life; weight history, including body mass index and post-diagnosis weight gain; and physical activity. Logistic regressions were used to determine if these covariates were associated with meeting [>8.3 metabolic equivalent task (MET) hr/wk]; partially meeting (4.15–8.3 MET hr/wk); or not meeting (<4.15 MET hr/wk) PAGs.

Results: Only 54% of AA BCSs reported meeting current PAGs. Participants reporting weight gain of ≤5 lbs post-diagnosis, and those who received surgical treatment for breast cancer were more likely to complete at least 8.3 MET hr/wk. Better physical functioning and lesser pain intensity were associated with meeting PAGs.

Conclusion: Several factors influence physical activity behaviors and are likely to be important in developing effective interventions to assist AA survivors manage their weight. It is essential that providers and breast cancer support groups that assist survivors to remain physically active and to manage their weight should be aware of these factors. These findings may help generate hypotheses for future research to undergird efforts to increase physical activity among African American BCSs.     

Experiences of general practitioners participating in oncology meetings with specialists to support GP-led survivorship care; an interview study from the Netherlands

Background: Due to ageing, increasing cancer incidence and improved treatment, the number of survivors of cancer increases. To overcome the growing demand for hospital care survivorship by the involvement of the general practitioner (GP) has been suggested. Dutch GPs started a project to offer survivorship care to their patients with the help of monthly oncology meetings with hospital specialists.

Objectives: To evaluate the experiences of GPs with monthly oncology meetings in a GP-practice to support GP-led survivorship care of colon cancer patients.

Methods: This is a qualitative study in primary care centres in a region in the Netherlands around one hospital. GPs were recruited from practices organizing monthly oncology meetings with hospital specialists. Ten of 15 participating GPs were interviewed until saturation. The interviews were transcribed verbatim and two independent researchers analysed the data.

Results: The oncology meetings and individual care plans attributed to a feeling of shared responsibility for the patients by the GP and the specialist. The meetings helped the GPs to be informed about the patients in the diagnostic and treatment phase, which was followed by a clear moment of transfer from hospital to primary care. GPs were better equipped to treat comorbidity and were more confident in providing survivorship care. Due to lack of reimbursement for survivorship care, the internal motivation of the GP must high.

Conclusion: The oncology meetings fulfil the need for information and communication. Close cooperation between GPs and oncology specialists appears to be an essential factor for GPs to value GP-led survivorship care positively.     

Patients’ experience with cancer care: A qualitative study in family practice

Abstract

Background: Continuity is an important aspect of cancer care that is often a challenge owing to the movement of patients between family practice, cancer clinics, and hospitals.

Objectives: To investigate the experiences of cancer patients in relation to continuity of care.

Methods: A qualitative study was conducted in a family practice setting. Semi-structured interviews were used for data collection. 10 cancer patients with a wide variation in their disease duration and experiences with medical care were interviewed. Open questions were used to encourage patients to express their personal experiences with cancer care. The interviews were recorded, transcribed and analysed by three researchers using thematic analysis.

Results: Cancer patients experienced a lack of information concerning cancer and its treatment. They also perceived that the cancer treatment made them suffer. In the patients’ opinion, the family doctor has a limited role in cancer care. However, the patients felt that the family doctor should be aware of their health. The patients’ satisfaction with the oncologist's care was high. They considered that their role in cancer care was to mediate an exchange of information between the oncologist and the family doctor.

Conclusion: Cancer patients experience continuity of care in several ways: continuity in cancer care should be implemented by co-ordinating activities, such as regular check-ups, a clear timeframe and provision of adequate information. In addition, communication between the primary and secondary sector could be improved.     

Mapping oncology services in regional and rural Australia

Objective: To map clinical oncology services in regional and rural Australia. Design and setting: A self‐administered survey was sent to 161 regional hospitals administering chemotherapy (RHAC) in Australia. RHAC were categorised by state, Hospital Peer Group and the Australian Standard Geographical Classification (ASGC) Remoteness Areas classification. Main outcome measure(s): Survey data provided percentage and aggregate figures about availability of medical, radiation and surgical oncologists, chemotherapy nurses, breast cancer nurses, palliative care physicians and allied health professionals according to remoteness and state. Chemotherapy prescribing practices, adherence to occupational health and safety guidelines and availability of multidisciplinary clinics were also explored. Results: A 98% survey completion rate was achieved. Significant deficiencies in service provision were identified in RHAC. Only 21% of RHAC reported a resident medical oncology service, 7% had a radiation oncology unit, and 6% had a resident surgical oncologist. Only 24% of RHAC reported a dedicated palliative care specialist and 39% identified a dedicated oncology counselling service. Other issues included administration of chemotherapy by nurses outside a recognised facility or by nurses without recognised oncology training, limited availability of funded breast care nurses and lack of multidisciplinary clinics. Conclusion: Survey data highlight marked cancer service deficiencies in rural and regional Australia. It is not unreasonable to conclude that these deficiencies might contribute to poorer outcomes for cancer patients living in these areas. The results suggest the need for short‐ and long‐term measures to improve access to best‐practice cancer services for patients living in regional, rural and remote areas of Australia.     

Youth Preferences for Weight-Related Conversations

ABSTRACT

Little guidance is available to clinicians on how to talk about weight with their patients. The aim of this study is to explore youth preferences for weight-related conversations. Participants came from the National MyVoice Text Message Cohort. Between 7/2017 and 01/2018, 952 MyVoice participants provided open-ended responses via text message to three questions about weight-related conversations (“Has your doctor ever talked to you about weight?”, “What did he or she say?”, and “What should a doctor NOT say when talking about weight?”). The presence of themes was coded using standard qualitative methods. Of the 952 respondents, 568 (60%) reported that their doctor had talked with them about weight. Of these, 85% indicated that their doctor had notified them of their weight, BMI, or weight status and/or the need to change their body weight and 16% had doctors who provided advice about weight control. Eight themes emerged from the analysis of responses to the question “What should a doctor NOT say when talking about weight?”. The two most common themes were: (1): Avoid stigmatizing terms/language (32%); and (2) Do not shame patient for their weight (25%). Findings suggest that weight-related conversations do not reflect the preferences of the youth they are designed to benefit. Youth recommended that clinicians focus on health and sustainable behavioral solutions, avoid stigmatizing language and comparing them to others, and be aware of the potential harm associated with making assumptions that conflate weight with health behaviors, morality, or appearance.     

More Frequent Nutrition Counseling Limits Weight Loss and Improves Energy Intake During Oncology Management: A Longitudinal Inpatient Study in Taiwan

Introduction: Malnutrition increases the risk of cancer treatment-related complications. Nutritional intervention is beneficial for the outcomes of outpatients with cancer. This study investigated the impacts of nutrition consultation and care on energy intake and weight change in inpatients receiving cancer treatment.

Methods: We conducted a longitudinal study, enrolling 3221 inpatients with head and neck, lung, hepatobiliary, upper gastrointestinal, colorectal, breast, or gynecological cancer who received at least two nutrition consultations between April 2010 and July 2015. In every consultation, a dietitian calculated the total energy requirement and the actual energy intake was assessed using a 24-h dietary recall.

Results: Patients with head and neck cancer lost the most weight (1.16?kg/mo). For every consultation, a 0.03-kg weight gain per month was observed (P?=?0.001). The average energy consumption percentage (% estimated energy requirement) at the third consultation was 87.0%. After controlling for potential covariates, the energy consumption percentages at the third, fourth, fifth–seventh, eighth, and subsequent consultations were significantly higher than those at the first consultation (P?<?0.05).

Conclusion: For oncology inpatients, routine screening and at least three active nutrition consultations with dietitians effectively improved energy intake and preserved body weight.     

Measurement of Muscle Mass and Sarcopenia Using Anthropometry,Bioelectrical Impedance,and Computed Tomography in Surgical Patients with Colorectal Malignancy: Comparison of Agreement Between Methods

Abstract

Background: Low skeletal muscle index (SMI) and sarcopenia adversely affect clinical outcomes in oncology patients. Study aims were to assess the agreement of bioelectrical impedance analysis (BIA), mid-arm muscle circumference (MAMC), and computed tomography (CT) at the third lumbar vertebra (L3), for the measurement of muscle mass and identification of sarcopenia, in patients with colorectal cancer (CRC).

Method: A comparison study of low SMI and sarcopenia determined by BIA and MAMC, compared to CT. Sensitivity, specificity and area under the curve (AUC) were calculated.

Results: CT scans were obtained for 100 participants. Low SMI was identified in 29%, 57%, and 20% of participants using CT at L3, BIA, and MAMC, respectively. For low muscle mass BIA showed 60% of participants were correctly classified (AUC 0.619, sensitivity 80%, specificity 52%, kappa 0.241, P?=?0.009) and for MAMC, 73% of participants were correctly classified (AUC 0.625, sensitivity 38%, specificity 88%, kappa 0.286, P?=?0.005). There were 14%, 31%, and 10% of participants identified as having sarcopenia from CT, BIA, and MAMC, respectively.

Conclusions: Both BIA and MAMC show a poor level of agreement for measuring muscle mass compared to CT scans using L3 in patients with CRC.     

The Potential Influence of Dietary Counseling on Nutritional Status and Dietary Supplement Consumption in Breast Cancer Patients: A Pilot Study

Introduction: Cancer, in particular breast cancer, is one of the leading causes of death among women. Good nutritional status contributes to the efficacy of treatment and recovery, and nutritional interventions can minimize the adverse effects of cancer therapy.

Aim: The aim of this study was to describe the potential role of dietary counseling in breast cancer patients. The impact of nutritional advice on the nutritional status of patients, the use of dietary supplements, and the knowledge of phytoestrogens were assessed.

Materials and Methods: The study was conducted between April and July 2016 in the Lublin Oncology Center on a group of 173 female patients undergoing breast cancer treatment. The patients filled out a questionnaire containing 34 open-ended and closed-ended questions. The collected data were processed in Excel and Statistica 5.0 programs, and the results were regarded as significant at P?<?0.05.

Results: The mean age of the evaluated patients was 66.8?±?11.3 years. The duration of disease was significantly correlated with the patients’ nutritional status expressed by the body mass index (P?=?0.0368). The main sources of knowledge about nutrition in cancer care were nurses (29.71%), physicians (12.31%), and nutritionists (13.78%). Patients who received nutritional advice had significantly greater knowledge about phytoestrogens (P?=?0.0001), and they were of the opinion that a diet rich in phytoestrogens was safe (P?=?0.001). More than 85% of the polled subjects used dietary supplements during treatment, and 2/3 of them did so without professional advice. In this study, 73.07% of the respondents regularly monitored their body weight. Patients who did not receive dietary advice less frequently informed their physician about weight changes.

Conclusions: The nutritional status of patients was correlated with access to nutrition and dietary advice during illness. The risk of malnutrition was minimized when patients received and understood educational materials. The patients who did not receive dietary advice more frequently overdosed on dietary supplements. Phytoestrogens were more widely used by patients who regularly attended a dietitian.     

Was a decision made? An assessment of patient–clinician discordance in medical oncology encounters

BackgroundShared decision making is promoted to improve cancer care quality. Patients and clinicians may have different ideas about what constitutes a cancer care decision, which may limit the validity of self‐reported measures of shared decision making. We sought to estimate the extent to which patients and clinicians agree on whether a cancer care decision was made during an outpatient encounter.MethodsWe surveyed patients and clinicians immediately after an oncology encounter at a large, tertiary medical centre and calculated agreement in response to the single‐item question, ‘Was a specific decision about cancer care made during the appointment today?’ Answer options were ‘yes’ and ‘no’. Participants were 315 oncology patients, with any solid tumour malignancy and at any stage of management, and their clinicians (22 staff oncologists, nine senior fellows and five nurse practitioners).ResultsPatients and clinicians reported having made a cancer care decision in 184 (58%) and 174 (55%) of encounters, respectively. They agreed on whether a cancer care decision was made in 213 (68%) of encounters (chance‐adjusted agreement was 0.34); in 56 of the 102 discordant encounters, the patient reported making a decision while the clinician did not. We found no significant correlates with discordance.ConclusionsPatients and clinicians do not always agree on whether a cancer care decision was made. As such, measures that ask patients and/or clinicians to evaluate a decision‐making process or outcome may be methodologically insufficient when they do not explicitly orient respondents towards the thing they are being asked to assess.     

Disentangling Associations of Children's Sports Participation and Compulsive Exercise With Parenting Practices and Child Disordered Eating Behavior

PurposeExercise can enhance health and well-being. Exercise can also, when it is highly driven and compulsive, reflect eating disorder psychopathology. The present study examined associations of compulsive exercise and youth athletics with child disordered eating behaviors (overeating, binge eating, and secretive eating) and with parenting practices related to eating and weight, including how parents talk to their children about weight.MethodsParticipants were parents (N = 875) who completed an online cross-sectional survey. Parents reported whether their child was an athlete and how often their child exercised in a “driven” or “compulsive” way to control their weight. Four groups were compared: child athletes with compulsive exercise (Group AE: n = 34, 3.9%), athletes without compulsive exercise (Group A: n = 314, 35.9%), nonathletes with compulsive exercise (Group E: n = 40, 4.6%), and nonathletes without compulsive exercise (Group X: n = 487, 55.7%).ResultsThere was a significant, graded association of eating/weight-related parenting: parents of Group E children had the most negative eating/weight-related parenting, followed by parents of Group AE children, followed by both noncompulsive exercise groups (Group A and Group X). Parents reported significantly more “fat talk” in both compulsive exercise groups (Group AE and Group E) than noncompulsive exercise groups (Group A and Group X). Significantly more youth had regular disordered eating behaviors (overeating, binge eating, and secretive eating) in compulsive exercise groups (Group AE and Group E) compared with noncompulsive exercise groups (Group A and Group X).ConclusionsOverall, relatively few youth were categorized as engaging in compulsive exercise. However, compulsive exercise, particularly among nonathletes, was consistently associated with both disordered eating behaviors and eating/weight-related parenting practices. Stronger associations emerged for compulsive exercise than child athletics.     

Breast cancer and serum organochlorine residues

Background: Controversy still exists about the breast carcinogenic properties in humans of environmental xenoestrogens (organochlorines), justifying new investigations.

Aims: To compare the blood levels of total dichlorodiphenyltrichloroethane (DDT) and hexachlorobenzene (HCB) in samples collected at the time of breast cancer discovery, in order to avoid the potential consequences of body weight change (after chemotherapy or radiotherapy) on the pesticide residue levels.

Methods: Blood levels of HCB and total DDT (we calculated total DDT concentrations by adding all DDT and DDE isomers) were compared in 159 women with breast cancer and 250 presumably healthy controls. Risk of breast cancer associated with organochlorine concentration was evaluated.

Results: Mean levels of total DDT and HCB were significantly higher for breast cancer patients than for controls. No differences in serum levels of total DDT or HCB were found between oestrogen receptor positive and oestrogen receptor negative patients with breast cancer.

Conclusions: These results add to the growing evidence that certain persistent pollutants may occur in higher concentrations in blood samples from breast cancer patients than controls.

     

Association between Scored Patient-Generated Subjective Global Assessment and Skeletal Muscle Determined by Computed Tomography in Patients with Cervical Cancer

Abstract

Introduction: Myopenia is a significant problem in oncology patients and the use of reliable instruments for its identification in clinical practice is necessary.

Objective: To evaluate the association between the Scored Patient-Generated Subjective Global Assessment (PG-SGA) and skeletal muscle (SM) measured by computed tomography (CT) in patients with cervical cancer.

Methods: This is an observational, cross-sectional study which enrolled women with cervical cancer, over 20?years, who started treatment between January 2015 and September 2018. The ones who presented PG-SGA and imaging of CT with a maximum interval of 45?days between them were included. The SM index (SMI) was used to classify myopenia and a significance level of 5% was adopted.

Results: According to the PG-SGA, malnutrition was found in 56% patients and 23% were classified with myopenia by CT. The PG-SGA parameters were significantly associated with the SMI. The cutoff points that best discriminated myopenia were the PG-SGA total score ≥ 10, muscle depletion ≥ 2.0, and physical examination score ≥ 2.0.

Conclusion: The PG-SGA showed to be a useful and viable method that shows good association and correlation with the SMI.     

Comparing EQ-5D-3L and EQ-5D-5L performance in common cancers: suggestions for instrument choosing

Purpose

To compare the performance of three-level EuroQol five-dimensions (EQ-5D-3L) and five-level EuroQol five-dimensions (EQ-5D-5L) among common cancer patients in urban China.

Methods

A hospital-based cross-sectional survey was conducted in three provinces from 2016 to 2018 in urban China. Patients with breast cancer, colorectal cancer, or lung cancer were recruited to complete the EQ-5D-3L and EQ-5D-5L questionnaires. Response distribution, discriminatory power (indicator: Shannon index [H′] and Shannon evenness index [J′]), ceiling effect (the proportion of full health state), convergent validity, and health-related quality of life (HRQoL) were compared between the two instruments.

Results

A total of 1802 cancer patients (breast cancer: 601, colorectal cancer: 601, lung cancer: 600) were included, with the mean age of 55.6 years. The average inconsistency rate was 4.4%. Compared with EQ-5D-3L (average: H′?=?1.100, J′?=?0.696), an improved discriminatory power was observed in EQ-5D-5L (H′?=?1.473, J′?=?0.932), especially contributing to anxiety/depression dimensions. The ceiling effect was diminished in EQ-5D-5L (26.5%) in comparison with EQ-5D-3L (34.5%) (p?<?0.001), mainly reflected in the pain/discomfort and anxiety/depression dimensions. The overall utility score was 0.790 (95% CI 0.778–0.801) for EQ-5D-3L and 0.803 (0.790–0.816) for EQ-5D-5L (p?<?0.001). A similar pattern was also observed in the detailed cancer-specific analysis.

Conclusions

With greater discriminatory power, convergent validity and lower ceiling, EQ-5D-5L may be preferable to EQ-5D-3L for the assessment of HRQoL among cancer patients. However, higher utility scores derived form EQ-5D-5L may also lead to lower QALY gains than those of 3L potentially in cost-utility studies and underestimation in the burden of disease.

     

Nutritional Intervention for Nonsurgical Head and Neck Cancer Patients Treated with Radiation Therapy: Results from a Prospective Stepped-Wedge Clinical Protocol

Aim: To evaluate the impact on weight loss (WL) of a standardized nutritional stepped-wedge protocol on consecutive head and neck cancer (HNC) patients treated with curative radiotherapy (RT).

Methods: We prospectively collected data of patients followed by a trained dietitian and treated according to a pre-defined stepped-wedge protocol. Patients with swallowing defect at the baseline and WL >10% 3 months prior to the beginning of RT were excluded from the analysis. Nutritional status was assessed at the baseline and weekly during the course of RT. Fluid and caloric intake were assessed through a 24-h recall.

Results: Between May 2010 and March 2011, 42 patients treated were evaluated. Median overall treatment time was 52.5 days. WL per CTCAE 4.03 was G0, G1 and G2 in 23 (55%), 14 (33%) and 5 (12%) patients, respectively. Thirty-five (83%) patients did not require enteral nutrition. About 90% of patients completed RT without interruption of oral feeding.

Conclusions: Despite the high toxicity profile of curative RT in HN, we proposed a standardized stepped-wedge protocol allowing to prevent severe WL in most of our patients. Further larger prospective studies are warranted to validate our approach and to achieve consensus on nutritional intervention in this subset of patients.     

Psychosocial Concerns and Weight Control Behaviors Among Overweight and Nonoverweight Native American Adolescents

Objective To compare the psychosocial and weight-related concerns and weight control, eating, and exercise behaviors of overweight and nonoverweight Native American adolescents living on or near reservations.Study design A cross-sectional survey assessed psychosocial, health, and weight-specific concerns; disordered eating; and health-promoting behaviors.Study population The study population included 11,868 Native American youth in grades 7 through 12.Statistical analyses performed Analyses of variance and χ² tests were used to examine associations between weight status and psychosocial and weight-related concerns and behaviors. Stratified analyses were done by gender and by gender and age.Results Self-reported weights and heights indicated that 25% of the study population was overweight. Overweight youth were twice as likely to report health concerns as nonoverweight youth. Although a high percentage of nonoverweight youth expressed body- or weight-related concerns and reported engaging in disordered eating behaviors, prevalence rates for these concerns were significantly higher among overweight youth. Overweight youth were also somewhat less likely to engage in health-promoting behaviors. In contrast, differences in global psychosocial concerns were minimal.Applications Overweight Native American youth were concerned about their weight, but did not appear to have major psychosocial concerns associated with being overweight. Interventions aimed at obesity prevention and overall health promotion are essential, given the high prevalence of obesity and of psychosocial and weight-related concerns and behaviors among the study population as a whole. The challenge is to develop culturally appropriate interventions aimed at the promotion of healthful weight control behaviors that will not lead to negative psychosocial consequences.
