RESUMO
OBJECTIVES: Loss of appetite in older adults can lead to malnutrition, weight loss, frailty, and death, but little is known about its epidemiology in the United States (US). The objective of this study was to estimate the annual prevalence and incidence of anorexia in older adults with Medicare fee-for-service (FFS) health insurance. DESIGN: Retrospective and observational analysis of administrative health insurance claims data. SETTING: This study included Medicare FFS claims from all settings (eg, hospital inpatient/outpatient, office, assisted living facility, skilled nursing facility, hospice, rehabilitation facility, home). PARTICIPANTS: This study included all individuals aged 65 to 115 years old with continuous Medicare FFS medical coverage (Parts A and/or B) for at least one 12-month period from October 1, 2015, to September 30, 2021 (ie, approximately 30 million individuals each year). INTERVENTION: Not applicable. MEASUREMENTS: Anorexia was identified using medical claims with the ICD-10 diagnosis code "R63.0: Anorexia". This study compared individuals with anorexia to a control group without anorexia with respect to demographics, comorbidities using the Charlson Comorbidity Index (CCI), Claims-based Frailty Index (CFI), and annual mortality. The annual prevalence and incidence of anorexia were estimated for each 12-month period from October 1, 2015, to September 30, 2021. RESULTS: The number of individuals with anorexia ranged from 317,964 to 328,977 per year, a mean annual prevalence rate of 1.1%. The number of individuals newly diagnosed with anorexia ranged from 243,391 to 281,071 per year, a mean annual incidence rate of 0.9%. Individuals with anorexia had a mean (±standard deviation) age of 80.5±8.7 years (vs 74.9±7.5 years without anorexia; p<.001), 64.4% were female (vs 53.8%; p<.001), and 78.4% were White (vs 83.2%; p<.001). The most common CCI comorbidities for those with anorexia were chronic pulmonary disease (39.4%), dementia (38.3%), and peripheral vascular disease (38.0%). Median (interquartile range [IQR]) CCI with anorexia was 4 [5] (vs 1 [3] without anorexia; p<.001). The annual mortality rate among those with anorexia was 22.3% (vs 4.1% without anorexia; relative risk 5.49 [95% confidence interval, 5.45-5.53]). CONCLUSION: Approximately 1% of all adults aged 65-115 years old with Medicare FFS insurance are diagnosed with anorexia each year based on ICD-10 codes reported in claims. These individuals have a higher comorbidity burden and an increased risk of annual mortality compared to those without a diagnosis of anorexia. Further analyses are needed to better understand the relationship between anorexia, comorbidities, frailty, mortality, and other health outcomes.

BACKGROUND: Clinical frailty scales (CFS) predict hospital-related outcomes. Frailty is more common in areas of higher socioeconomic disadvantage, but no studies exclusively report on the impact of CFS on hospital-related outcomes in areas of known socioeconomic disadvantage. AIMS: To evaluate the association of the CFS with hospital-related outcomes. DESIGN: Retrospective observational study in a community hospital within a disadvantaged area in Australia (Social Economic Index for Areas = 0.1%). METHODS: The CFS was used in the emergency department (ED) for people aged ≥ 75 years. Frailty was defined as a score of ≥4. Associations between the CFS and mortality, admission rates, ED presentations and length of stay (LOS) were analysed using regression analyses. RESULTS: Between 11 July 2017 and 31 March 2018, there were 5151 ED presentations involving 3258 patients aged ≥ 75 years. Frail persons were significantly more likely to be older, represent to the ED and have delirium compared with non-frail persons. CFS was independently associated with 28-day mortality, with odds of mortality increasing by 1.5 times per unit increase in CFS (95% CI: 1.3-1.7). Frail persons with CFS 4-6 were more likely to be admitted (OR: 1.2; 95% CI: 1.0-1.5), have higher geometric mean LOS (1.43; 95% CI 1.15-1.77 days) and higher rates of ED presentations (IRR: 1.12; 95% CI 1.04-1.21) compared with non-frail persons. CONCLUSIONS: The CFS predicts community hospital-related outcomes in frail persons within a socioeconomic disadvantage area. Future intervention and allocation of resources could consider focusing on CFS 4-6 as a priority for frail persons within a community hospital setting.

OBJECTIVES: Health impact assessment (HIA) is a systematic process that can be used by public health professionals to examine the potential health effects of a policy, plan, program, or project that originates outside of the health sector. This article presents a case study of how an interdisciplinary team utilized an HIA to analyze the potential health impact of full-day kindergarten (FDK) on communities in Nevada. STUDY DESIGN: Case study. METHODS: With stakeholder and community engagement, we conducted a multistage HIA that included qualitative and quantitative data collection and analysis, a review of existing literature, and projections. The team considered several pathways through which FDK could impact health in Nevada: (1) school performance; (2) physical development (physical activity and nutrition education); and (3) access to school-based meals and health screenings. RESULTS: Findings indicated that access to FDK could enhance opportunities for Nevada's children to harness school-based services, increase physical activity, and promote nutrition education. In addition, based on existing research that suggests relationships between (1) FDK attendance and 3rd and 5th grade math and reading standardized test scores and (2) 3rd and 5th grade test scores and high school graduation, as well as available state and national data, we estimated that access to FDK could increase high school graduation in Nevada by 499-820 students per year. CONCLUSIONS: This HIA demonstrated that access to FDK could impact both student and adult health in Nevada. Our engagement of public health professionals along with stakeholders and the community in the HIA process demonstrated that HIAs can be an important tool for public health professionals to examine the effects on community health of policies, programs, plans or projects that arise outside of the health sector.

Current criteria identifying patients with ultra-high risk of psychosis (UHR) have low specificity, and less than one-third of UHR cases experience transition to psychosis within 3 years of initial assessment. We explored whether a Bayesian probabilistic multimodal model, combining baseline historical and clinical risk factors with biomarkers (oxidative stress, cell membrane fatty acids, resting quantitative electroencephalography (qEEG)), could improve this specificity. We analyzed data of a UHR cohort (n=40) with a 1-year transition rate of 28%. Positive and negative likelihood ratios were calculated for predictor variables with statistically significant receiver operating characteristic curves (ROCs), which excluded oxidative stress markers and qEEG parameters as significant predictors of transition. We clustered significant variables into historical (history of drug use), clinical (Positive and Negative Symptoms Scale positive, negative and general scores and Global Assessment of Function) and biomarker (total omega-3, nervonic acid) groups, and calculated the post-test probability of transition for each group and for group combinations using the odds ratio form of Bayes' rule. Combination of the three variable groups vastly improved the specificity of prediction (area under ROC=0.919, sensitivity=72.73%, specificity=96.43%). In this sample, our model identified over 70% of UHR patients who transitioned within 1 year, compared with 28% identified by standard UHR criteria. The model classified 77% of cases as very high or low risk (P>0.9, <0.1) based on history and clinical assessment, suggesting that a staged approach could be most efficient, reserving fatty-acid markers for 23% of cases remaining at intermediate probability following bedside interview.

AIM: Restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis (IPAA) is the most frequently performed operation for intractable ulcerative colitis (UC) and for many patients with familial adenomatous polyposis (FAP). It can be complicated by a functional evacuation difficulty, which is not well understood. We aimed to evaluate the role of defaecating pouchography in an attempt to assess the mechanism of evacuation difficulty in pouch patients. METHOD: All RPC patients who had had a defaecating pouchogram for evacuation difficulty at one hospital between 2006 and 2014 were retrospectively reviewed. The findings and features were correlated with the symptoms. Demographic, clinical and radiological variables were analysed. RESULTS: Eighty-seven [55 (63%) female] patients aged 47.6 ± 12.5 years (mean standard ± SD) were identified. Thirty-five had a mechanical outlet obstruction and 52 had no identified mechanical cause to explain the evacuation difficulty. The mean age of these 52 [33 (63%) female] patients was 48.2 ± 13 years. Of these 52 patients, significantly more used anti-diarrhoeal medication (P = 0.029), complained of a high frequency of defaecation (P = 0.005), experienced a longer time to the initiation of defaecation (P = 0.049) and underwent pouchoscopy (P = 0.003). Biofeedback appeared to improve the symptoms in 7 of 16 patients with a nonmechanical defaecatory difficulty. The most common findings on defaecating pouchography included residual barium of more than 33% after an attempted evacuation (46%, n = 24), slow evacuation (35%, n = 18) and mucosal irregularity (33%, n = 17). Correlation between radiological features and symptoms showed a statistically significant relationship between straining, anal pain, incontinence and urgency with patterns of anismus or pelvic floor descent or weakness seen on the defaecating pouchogram. Symptoms of incomplete evacuation, difficulty in the initiation of defaecation, high defaecatory frequency and abdominal pain were not correlated with the radiological features of the pouchogram. CONCLUSION: Defaecating pouchography may be useful for identifying anismus and pelvic floor disorders in pouch patients who have symptoms of straining, anal pain or incontinence. In patients with a high frequency of defaecation and abdominal pain it does not provide clinically meaningful information. Patients who complain of straining, incontinence, anal pain or urgency and have anismus or pelvic floor disorders may benefit from behavioural therapy.

BACKGROUND AND AIMS: Estimate costs for health and social care services in managing older people in the community who fall. METHOD AND RESULTS: Analyses of predominantly national databases using cost of illness methodologies. In Scotland, 294,000 (34%) of people over 65 years and living in the community fall at least once a year. Of these 20%, almost 60,000 people contacted a medical service for assistance. There were almost 30,000 attendances at GP practices, over 36,100 calls to the Scottish Ambulance Service and 46,816 people presenting at A&E, with 16,549 admitted, 30% with a hip fracture. Mortality was high, 7% during the hospital stay, rising to over 12% at 1 year. Over 20% of patients were unable to return to their homes. Associated costs were over £470 million, with 60% incurred by social services, mainly providing long-term care. Cost per person falling was over £1720, rising to over £8600 for those seeking medical assistance. A hip fracture admission cost £39,490, compared with £21,960 for other falls-related admissions. CONCLUSIONS: Transparent, robust cost information demonstrates the substantial burden of falls for health and social care services and should be a driver for implementing evidence-based interventions to reduce falls.

OBJECTIVE: Desmoid tumour is a common extraintestinal manifestation of patients with familial adenomatous polyposis (FAP) who have undergone prophylactic colectomy. We aimed to determine whether MRI provides equivalent or better assessment of desmoid tumours than CT, the current first-line investigation. METHODS: Following ethics approval and informed consent, FAP patients with known desmoid tumour underwent contrast-enhanced 64-slice multidetector CT (MDCT) and 1.5 T MRI (incorporating T(1) weighted, T(2) weighted, short tau inversion-recovery and T(1) weighted with contrast, axial, sagittal and coronal sequences). The number, site, size, local extent, tumour signal intensity and desmoid-to-aorta enhancement ratio were analysed. RESULTS: MRI identified 23 desmoid tumours in 9 patients: 9 intra-abdominal desmoid (IAD) tumours, 10 abdominal wall desmoid (AWD) tumours and 4 extra-abdominal desmoid (EAD) tumours. CT identified only 21 desmoids; 1 EAD and 1 AWD were not identified. The two modalities were equivalent in terms of defining local extent of desmoid. Five IAD tumours involved the bowel, six caused ureteric compression and none compromised the proximal superior mesenteric artery. There was no difference in median desmoid size: 56.7 cm(2) (range 2-215 cm(2)) on MDCT and 56.3 cm(2) (3-215 cm(2)) on MRI (p=0.985). The mean MRI enhancement ratio, at 1.12 (standard deviation 0.43), was greater than the CT enhancement ratio, which was 0.48 (0.16) (p<0.0001). High signal intensity on T(2) MRI was associated with increased MRI enhancement ratio (p=0.006). CONCLUSIONS: MRI is at least equivalent (and may be superior) to MDCT for the detection of desmoid tumours in FAP. Coupled with the advantage of avoiding radiation, it should be considered as the primary imaging modality for young FAP patients.

BACKGROUND: The risk factors for food allergy (FA) and anaphylaxis remain uncertain. OBJECTIVE: We examined the association between socio-economic status (SES), geographic remoteness and childhood FA and anaphylaxis in Australia. METHODS: Sales of infant hypoallergenic formulae (IHF; 2008-2009) and EpiPens (2006-2007) in children aged 0-4 years and hospital anaphylaxis admission rates (2002-2006) in age groups 0-4, 5-14, 15-24, 25-64 and 65+ years were used as proxy markers of FA and anaphylaxis in Australia. Government and commercially derived data were analysed by SES and geographic remoteness (very remote, remote, outer regional, inner regional and major cities). RESULTS: Annual IHF sales rates were higher in those with the greatest compared with the least socio-economic advantage (47,830 vs. 21,384 tins/100,000 population; P<0.001). EpiPen sales trends were also higher in those with the greatest socio-economic advantage in all age groups, most marked in those aged 0-4 (1713 vs. 669/100,000; P=0.002) and 5-14 years (1628 vs. 600/100,000; P=0.001). Formula sales rates were higher in major cities than remote/very remote regions (37,421 vs. 6704/100,000; P<0.001) with similar EpiPen sales trends, particularly in ages 0-4 (1166 vs. 601/100,000; P=0.045) and 5-14 years (1099 vs. 588/100,000; P<0.001). Socio-economic advantage and geographic remoteness remained statistically significant in multivariable analysis of prescription rates (P<0.01) and were unchanged by adjustment for health services access. While anaphylaxis admission rates were higher in those with the greatest compared with the least socio-economic advantage in children aged 0-4 years (129 vs. 92/100,000 population/year; P=0.03), the opposite was observed in older age groups (e.g. aged 25-64 years: 43 vs. 76, P=0.01). There was no association between geographic remoteness and anaphylaxis admissions. CONCLUSION: Socio-economic advantage and residence in major cities may be risk factors for developing childhood FA and anaphylaxis. Further study will determine the extent to which economic factors and location of residence also influence access to health services.

Tractor rollovers are the most frequent cause of death in the farm community. Rollover protection structures (ROPS) can prevent the injuries and fatalities associated with these events; however, almost half of U.S. farms lack these essential devices. One promising strategy for increasing ROPS use is social marketing. The purpose of this study was to assess the costs associated with the New York ROPS Social Marketing Campaign in relation to the cost of fatalities and injuries averted as a result of the campaign to determine whether cost savings could be demonstrated in the initial years of program implementation. A total of 524 farmers who had retrofitted a tractor through the program were mailed a survey to assess the number of rollovers or close calls that occurred since ROPS installation. Responses were obtained from 382 farmers, two of whom indicated that they had a potential fatality/injury scenario since retrofitting their tractor through the program. The cost savings associated with the intervention was estimated using a decision-tree analysis adapted from Myers and Pana-Cryan with appropriate consumer price index adjustments. The data were compared to the cost of the New York ROPS Social Marketing Campaign to arrive at an associated cost-savings estimate relative to the intervention. This study indicates that a net savings will likely be demonstrated within the third year of the New York ROPS Social Marketing initiative. These data may provide evidence for researchers hoping to generate support from state and private agencies for similar initiatives.

There is tremendous variability in flavor profiles of sharp or aged U.S. cheddar cheese due to varied practices among commercial facilities and the lack of legal definitions for these terms. This study explored U.S. consumer perception and liking of commercial sharp or aged cheddar cheese profiles. Flavor profiles of 29 representative sharp cheddar cheeses were documented by descriptive sensory analysis with a trained panel. A total of 9 representative cheddar cheeses were selected and evaluated by consumers in 3 regional locations: east coast (Raleigh, N.C.; n = 150), midwest (Champaign, Ill.; n = 75), and west coast (Pullman, Wash.; n = 100). Consumers assessed the cheeses for overall liking and other consumer liking attributes. External preference mapping revealed 5 distinct consumer segments. The segment membership distribution between east coast and midwest consumers was similar while the west coast distribution was distinct (P < 0.05). A larger proportion of west coast consumers were present in segment 3, which consisted of consumers with specific likes for cheeses characterized by intense flavors of free fatty acid, brothy, and nutty flavors and salty and sour tastes. Consumer preferences in other segments differed from segment 3 due to their liking of at least 1 sensory attribute generally associated with young or mild cheddar cheese flavor. Key drivers of liking for these segments included whey flavor for segments 1 and 4 and milkfat flavor for segment 5. Segment 2 consumers liked most of the cheeses tested except those with dominant whey flavor. A sharp or aged cheddar cheese label means different things to different consumers and liking profiles are not defined by consumer location.

OBJECTIVE: One surgical option to treat failure after restorative proctocolectomy (RPC) is indefinite diversion (ID) without excision of the pouch. The study aimed to assess the mucosal morphology of the pouch and ileoanal anastomosis (IAA) over time after ID with particular reference to inflammation, dysplasia and carcinoma. METHOD: Patients with ID were identified from the hospital's Ileal Pouch Database. Individuals were invited by mail to attend for flexible pouchoscopy and biopsy from the ileal pouch and immediately distal to the IAA. RESULTS: Of 1822 patients on the database, 28 had undergone ID. Of these, 20 patients (18 ulcerative colitis, one familial adenomatous polyposis, one pseudo-obstruction) of median age 42 (18-67) years took part. There were eight males. The median (range) intervals from diagnosis of primary disease, pouch surgery and ID to the time of study were 221 (63-410), 146 (31-314) and 44 (10-159) months respectively. One patient had dysplasia in the original resection specimen. Five patients developed type C changes in the pouch. Of these three were identified between RPC and ID, one developed between ID and the present assessment and one was identified for the first time at the present assessment. No case of dysplasia or cancer was found in any of the biopsies. Rectal mucosa was found in biopsies from the IAA in four patients (three stapled; one handsewn); this was inflamed in three patients. CONCLUSION: At a median follow-up of 12 years after RPC and 3.6 years after indefinite diversion no instance of dysplasia or carcinoma in the ileal reservoir or distal to the IAA was found in any of the 20 patients having ID. Type C changes occurred at some time in five (25%) patients, indicating the importance of continued follow up.

AIMS: To discuss the practical aspects of conducting research in a primary care setting, from the perspectives of the practitioner and the research team. METHODS: Various issues are discussed, including the relevance of research questions being generated in this setting, the advantages to both parties and the processes involved in conducting a study in specialist practice. This paper describes two recent studies (a randomized clinical trial and a qualitative study) conducted within specialist practice, to illustrate some of the potential difficulties. CONCLUSIONS: The success of conducting a study in primary care is determined by a variety of factors, including an interested specialist practitioner, motivated staff in a well-organized practice and the close support of an academic-based research team.

Our discovery of high degrees of circular polarisation in some star-forming regions provides an attractive mechanism for the origin of homochirality. The largest degrees of circular polarisation, so far observed at near-infrared wavelengths, are thought to arise from the scattering of stellar radiation from aligned dust grains and are calculated to extend down to UV wavelengths. The extent of the region where circularly polarised light (CPL) of a single handedness originates is very large, and it is likely that the whole of a planetary system would see a single handedness of CPL also. We present the observational data, models of the scattering that leads to the production of CPL, and a model for the origin of homochirality. We also discuss briefly future laboratory and space-based experiments.

The AICPA's Statement of Position (SOP) 98-2 provides guidance on how a not-for-profit entity should account for costs associated with activities that involve a fund-raising component in combination with one or more mission-related components. Costs may be allocated among the various components of such an activity as long as the activity meets certain criteria specified by SOP 98-2. These criteria are related to the activity's purpose, audience, and content. If the activity does not meet the criteria, then all costs of the activity must be shown as fund-raising costs.

BACKGROUND: Increasing attention has been paid to the role of insurance in determining quality and outcomes of care. Pressures to reduce health costs and to improve quality have prompted attempts by managed care organizations to decrease the use of the emergency department (ED) for acute asthma, but performance comparisons between insurance types remain rare. METHODS: We used prospective data from the Multicenter Airway Research Collaboration on 965 children with acute asthma presenting to 36 EDs. We compared measures of quality of pre-ED care, acute severity, and short-term outcomes (length of stay, percent relapse, and percent with ongoing symptoms) across 4 different insurance categories: managed care, indemnity, Medicaid, and uninsured. We used multivariate regression to control for differences in education, estimated income, race/ethnicity, and chronic asthma severity and acute asthma characteristics. RESULTS: Children with managed care and indemnity had similar demographic and asthma characteristics, but these children differed significantly from Medicaid and uninsured patients. Managed care and indemnity insured children had similar ratings on all 7 quality measures, with Medicaid and uninsured children ranking significantly lower on most measures, including (1) percent with primary care provider (PCP) (P <.001), (2) percent using ED as usual site of asthma care (P <.001), (3) percent using ED for prescriptions (P <.001), (4) percent with a ratio of >1 of ED visits to acute office visits within the past year (P =.003), and (5) percent visiting their PCP within the week prior to ED visit (P <.001). Children with managed care were more acutely ill than were indemnity, Medicaid, or uninsured children on presentation to the ED (pulmonary index of 4.6, 4.0, 4.2, and 3.9, respectively, P =.007). There were no significant differences in length of hospital stay, relapse, and ongoing exacerbation. CONCLUSIONS: Our results indicate similar quality of care, greater severity of acute asthma, and no worse outcomes for children with managed care compared to children with indemnity insurance. We found uninsured children to have consistently poorer quality of care than insured patients.

This article reports on a series of structured interviews with immunization program officials in all 50 states regarding the effects of changes in federal policies and funding in the 1990s on the goals, priorities, and activities of state immunization programs. The purchase of vaccines is a major component of all state immunization programs. The Vaccines for Children (VFC) program, implemented in 1994, has become the primary source of vaccine purchase support in almost all states. A concern of many state immunization programs is their ability to ensure that vaccines are available to children who are not VFC eligible.State immunization programs also are involved in a myriad of activities necessary to ensure that children are adequately and appropriately immunized (e.g. , vaccine administration, outreach to parents). Federal funding to support these activities increased significantly during the mid-1990s, but was substantially reduced beginning in 1997. Because of these funding decreases, most states had to reduce the scale and scope of their immunization activities.State-level funding support for immunization programs varies, with state governments more likely to support vaccine purchase than immunization activities. Immunization will never be completed. Along with each new birth cohort, changes to the primary immunization schedule (i.e., addition of new vaccines and expansion of existing recommendations to encompass broader target groups) create ongoing needs for vaccine purchase and other immunization activities. Long-term immunization planning must reflect these continually expanding needs.

OBJECTIVES: Selective serotonin reuptake inhibitor (SSRI) prescriptions for children and adolescents have increased greatly in recent years despite a paucity of demonstrated safety and efficacy data and a lack of clear guidelines for use. Our study sought to describe family physician and pediatrician SSRI prescribing patterns for children and adolescents, identify influences on SSRI prescription variations, and describe the use of SSRI within the overall management of depression and other mental disorders in primary care. DESIGN: A survey was mailed to all 596 active North Carolina general pediatricians and a random sample of 557 family physicians in primary care practice. Family physicians who did not see children in their practice were excluded. The survey instrument consisted of a 4-page questionnaire. Survey items included physician demographics, practice characteristics, general management, volume of pediatric patients with depressive symptoms, prescription of SSRIs for depression and other diagnoses, and potential influences on SSRI prescribing practices. The main outcomes were self-reported physician prescription of SSRIs for children and adolescents. Results were analyzed using chi(2) comparisons and logistic regression. RESULTS: The overall response rate was 66% (55% family physicians and 76% pediatricians). Of the physicians, 72% had prescribed an SSRI for a child or adolescent. Depression was the most common reason for prescribing an SSRI; over two thirds of respondents had prescribed an SSRI for depression in a child 18 years of age or younger. Over half of the physicians reported they had prescribed an SSRI for a diagnosis other than depression in a child 18 years of age or younger. Attention-deficit/hyperactivity disorder was the most frequent use cited other than depression, followed by obsessive-compulsive disorder, aggression, eating disorders, and enuresis. Primary care physicians prescribed SSRIs for adolescents more commonly than for younger children. Only 6% of the respondents had ever prescribed an SSRI for a child younger than 6 years of age. In terms of SSRI prescriptions written for depression in the last 6 months, 32% of the physicians had recently prescribed SSRIs for adolescent patients and 6% for patients younger than 12 years of age. Family physicians were more likely than pediatricians to have recently prescribed SSRIs for adolescent patients (41% vs 26%), but there was no difference in recent SSRI prescriptions for children <12 years of age by physician specialty (4% vs 6%). Prescription of SSRIs was not associated with decreased use of counseling for treatment of depression, but prescription of SSRIs was associated with decreased use of referrals (63% vs 74%). There was no difference in the use of counseling between family physicians and pediatricians (61% vs 59%). However, pediatricians were more likely to use referrals in their usual approach to depression (77% vs 48%) compared with family physicians. More family physicians had prescribed SSRIs for pediatric patients compared with pediatricians (91% vs 58%), and more family physicians had prescribed SSRIs in combination with other psychotropic medications (54% vs 31%). For the majority of respondents, SSRI prescriptions constituted most of the medications used to treat childhood depression (75% of family physicians vs 61% of pediatricians). Family physicians were more likely to report a belief in the safety (63% vs 48%) and effectiveness (40% vs 32%) of SSRIs. Only 8% of physicians reported adequate training in the treatment of childhood depression and just 16% were comfortable with the treatment of depression. There were no specialty differences in training for the treatment of childhood depression; however, more family physicians than pediatricians agreed that they were comfortable with the management of childhood depression (22% vs 11%).

OBJECTIVE: To determine whether mifepristone-misoprostol medical abortion is more acceptable to some American women than to others. METHODS: Using previously reported acceptability data from a large US multicenter study (n = 2121), we conducted a more detailed analysis to test whether characteristics such as race/ethnicity, education, age, gestational age, and geographic location affect acceptability. RESULTS: In the United States, Asian women were more than twice as likely as other women to choose this method because they believed it was safer, while white women were twice as likely to select it because they considered it more natural. More educated women were likely to select this method to show support for greater choice and were more pleased about being able to avoid surgery. Particular features of the protocol also appealed to different women. White and African-American women as well as women with more education would feel significantly more comfortable taking one or both of the drugs at home than they would in the clinic. Nearly all groups of women were equally satisfied with this method and found it highly acceptable. The data showed surprisingly few differences among women's overall satisfaction level, their willingness to choose the method again, or to recommend it to others. CONCLUSION: Mifepristone-misoprostol medical abortion has widespread appeal to a broad range of women, but different women choose and prefer this method for different reasons.
