Course and outcome in individuals with atypical anorexia nervosa: Findings from the Study of Refeeding to Optimize iNpatient Gains (StRONG).

OBJECTIVE: We previously reported that participants with atypical anorexia nervosa (atypical AN) had higher historical and admission weights, greater eating disorder psychopathology, but similar rates of amenorrhea and weight suppression at baseline as compared to anorexia nervosa (AN); here, we compare 1-year outcomes. METHOD: Weight, % median body mass index (%mBMI), Eating Disorder Examination Questionnaire (EDE-Q) scores, resumption of menses, and rehospitalizations were examined at 3, 6, and 12 months post-discharge. Analyses (N = 111) compared changes in %mBMI, weight suppression, and EDE-Q scores over time between atypical AN and AN. RESULTS: Among the participants (48 atypical AN, 63 AN), both groups gained weight but those with atypical AN had lower gains than those with AN in %mBMI (p = .02) and greater weight suppression (p = .002) over time. EDE-Q scores improved over time, independent of weight suppression, with no significant difference between atypical AN and AN. Groups did not differ by rates of resumption of menses (80% atypical AN, 76.9% AN) or rehospitalization (29.2% atypical AN, 37.9% AN). Greater weight suppression predicted longer time to restore menses and more days of rehospitalization. DISCUSSION: Individuals with atypical AN regained a smaller proportion of body mass and were more weight suppressed over time. Change in eating disorder cognitions, resumption of menses, and rehospitalization rates at 1-year follow-up did not differ between groups. There was no significant difference in weight suppression between groups for those who were psychologically improved at 12 months. Findings highlight limitations in our understanding of weight recovery in atypical AN. New metrics for recovery are urgently needed. PUBLIC SIGNIFICANCE: Little is known about outcome in atypical anorexia nervosa (atypical AN). We examined recovery metrics in young people with atypical AN and anorexia nervosa (AN) 1 year after medical hospitalization. Individuals with atypical AN showed slower weight gain and remained further from their pre-illness weight. There were no differences in the rates of psychological recovery, resumption of menses, or rehospitalization. New metrics are needed to assess recovery in atypical AN.

Adolescents' Receipt of Care in a Medical Home: Results From a National Survey.

PURPOSE: Despite long-term emphasis on the medical home for children, little research focuses on adolescents. This study examines adolescent past-year attainment of medical home, its components, and subgroup differences among demographic and mental/physical health condition categories. METHODS: Utilizing the 2020-21 National Survey of Children's Health (NSCH), ages 10-17 (N = 42,930), we determined medical home attainment and its 5 components and subgroup differences utilizing multivariable logistic regression: sex; race/ethnicity; income; caregiver education; insurance; language spoken at home; region; and health conditions: physical, mental, both, or none. RESULTS: Forty-five percent had a medical home with lower rates among those who were as follows: not White non-Hispanic; lower income; uninsured; in non-English-speaking households; adolescents whose caregivers lacked a college degree; and adolescents with mental health conditions (p range = .01-<.0001). Differences for medical home components were similar. DISCUSSION: Given low medical home rates, ongoing differences and high mental illness rates, efforts are needed to improve adolescent medical home access.

Self-reported comorbid pains in severe headaches or migraines in a US national sample.

AIMS: To compare prevalence of self-reported comorbid temporomandibular joint muscle disorder-type, neck, back, and joint pains in people with severe headache or migraine; and analyze these self-reported pains in the 2000-2005 US National Health Interview Survey by gender and age for non-Hispanic whites, Hispanics, and non-Hispanic blacks (African Americans). METHODS: National Health Interview Survey data included information on gender, age, race, ethnicity, health status, and common pain types: severe headache or migraine, temporomandibular joint muscle disorder-type, neck, and low back in the last 3 months, as well as prior-month joint pains. Analyses included survey prevalence estimation and survey logistic regression to obtain odds ratios and 95% confidence intervals. RESULTS: The study included 189,967 adults: 48% males, 52% females; 73% white, 12% Hispanic, and 11% black. Of the entire sample, 29,712 (15%) reported severe headache or migraine, and 19,228 (64%) had severe headache or migraine with at least 1 comorbid pain. Two or more comorbid pains were reported in 10,200 (33%), with no gender difference, and with Hispanics (n = 1847 or 32%) and blacks (n = 1301 or 30%) less likely to report 2 or more comorbid pains than whites (n = 6747 or 34%) (odds ratio = 0.91, P = .032; OR = 0.82, P < .001, respectively). This group also reported significantly lower ratings of self-rated health (P < .001). Differences in type of comorbid pain by age patterns were found. CONCLUSIONS: Severe headache or migraine is often associated with other common pains, seldom existing alone. Two or more comorbid pains are common, similarly affecting gender and racial/ethnic groups.

Adolescent Technology-use Rules and Sleep in a Large Representative Sample.

PURPOSE: This study investigated the prevalence of technology-use rules, typical sleep habits, and associations between rules and sleep using the representative 2017-2018 California Health Interview Survey adolescent sample. METHODS: Adolescents aged 12-17 years completed the California Health Interview Survey, including queries of (1) rules at home regarding times to turn off or put away electronics and (2) school-night bedtime and rise time. Rates of rules and associations between rules and sleep were investigated using descriptive statistics and bivariate and multivariable analyses. RESULTS: Seventy-two percent reported technology-use rules. Rates were comparable across subgroups. Rules and sleep were not significantly associated after adjusting for covariates. Reported time in bed fell below National Sleep Foundation guidelines for 38% of participants. CONCLUSIONS: Most adolescents reported technology-use rules at home. Associations between rules and bedtime were mixed, suggesting that further exploration of contextual and developmental factors is needed. Many reported inadequate sleep duration, supporting sleep as a key topic in adolescent health.

Young Adult Anxiety or Depressive Symptoms and Mental Health Service Utilization During the COVID-19 Pandemic.

PURPOSE: Young adult anxiety/depression (mental health) symptoms have increased from prior to the COVID-19 pandemic. This study assessed young adult (aged 18-25 years) anxiety/depressive symptoms, mental health care utilization (prescription drug use, counseling, and/or either), and unmet counseling/therapy needs utilizing the national Household Pulse Survey data from June to July 2021. METHODS: Young adult (n = 2,809) rates and subgroup differences in mental health symptoms (Generalized Anxiety Disorder-2 and/or Patient Health Questionnaire-2) were assessed, as were mental health care utilization and unmet counseling/therapy needs. RESULTS: In total, 48% of young adults had mental health symptoms. Among those, 39% received treatment and 36% reported unmet mental health counseling/therapy needs. DISCUSSION: These findings highlight young adults' ongoing mental health needs and low services receipt. Interventions and further research to reduce barriers to seeking and utilizing mental health care and to increase the capacity of providers to deliver culturally appropriate mental health care are needed.

Renal Function in Patients Hospitalized With Anorexia Nervosa Undergoing Refeeding: Findings From the Study of Refeeding to Optimize Inpatient Gains.

PURPOSE: Among complications of malnutrition secondary to anorexia nervosa (AN) or atypical anorexia nervosa (AAN), renal impairment remains poorly elucidated. Evaluating renal function in hospitalized pediatric patients with AN and AAN undergoing refeeding will yield important information to guide clinicians in screening and managing renal dysfunction in this population. METHODS: This is a secondary analysis of data from the Study of Refeeding to Optimize Inpatient Gains trial, a multicenter randomized clinical trial comparing higher calorie refeeding versus lower calorie refeeding in 120 adolescents and young adults hospitalized with medical instability secondary to AN or AAN. Baseline disease characteristics were obtained. Vital sign measurements, weight, electrolytes, and fluid status were evaluated daily to ascertain medical stability. Renal function on admission and throughout hospitalization was quantified using daily creatinine measurement and calculation of the estimated glomerular filtration rate (eGFR) using the modified Schwartz equation. Regression analysis and mixed linear models were utilized to evaluate factors associated with eGFR. RESULTS: Of the 111 participants who completed treatment protocol, 33% had a baseline eGFR less than 90, suggesting renal impairment. Patients who experienced more rapid weight loss and more severe bradycardia were more likely to have low admission eGFR. While eGFR improved during refeeding, eGFR change by day based on refeeding treatment assignment did not reach statistical significance (95% confidence interval, -1.61, 0.15]; p = .095). DISCUSSION: Renal impairment is evident on admission in a significant number of adolescents and young adults hospitalized with AN and AAN. We demonstrate that short-term medical refeeding yields improvement in renal function.

Racial/Ethnic and gender prevalences in reported common pains in a national sample.

AIMS: To compare prevalences of self-reported temporomandibular joint and muscle disorders (TMJMD)-type pain, headaches, and neck and back pains in the 2000 to 2005 US National Health Interview Survey (NHIS) by gender and age for non-Hispanic Whites (Whites), Hispanics, and non-Hispanic Blacks (Blacks). METHODS: Data from the 2000 to 2005 NHIS included information on gender, age, race, ethnicity, and different common types of pain specifically: TMJMD-type pain, severe headaches/migraine, neck, and low back pains. RESULTS: A total of 189,992 people were included: 52% female and 48% male, 73% White, 12% Hispanic, 11% Black, and 4% "Other." The overall prevalence of TMJMD-type pain was 4.6%; severe headaches/migraine was 15.4%; neck, 14.9%; and low back, 28.0%. Survey logistic regression models estimating race-specific, age-adjusted curves revealed race by age pain differences. For TMJMD-type pain, White females presented the highest prevalence at younger ages, decreasing after age 40. Prevalences for Hispanic and Black females, although lower at younger ages, increased up to age 60 and remained higher than Whites. Males showed less racial/ethnic and age variation. Severe headaches/migraines presented an age pattern similar to TMJMD-type pain for White females and little overall variation for males, but without racial differences. Neck pain showed some similarities to TMJMD-type pain: higher in Whites at younger ages, lower at older ages, with Hispanics having the highest rates after their 60's. For low back pain, the rates peaked around the sixth decade for all racial/ethnic groups. CONCLUSION: The patterns of TMJMD-type pain varied greatly within and across racial/ethnic groups by gender and across the adult lifespan. Similarities and differences for the other pains were noted.

Temporomandibular joint and muscle disorder-type pain and comorbid pains in a national US sample.

AIMS: To compare prevalences of self-reported comorbid headache, neck, back, and joint pains in respondents with temporomandibular joint and muscle disorder (TMJMD)-type pain in the 2000-2005 US National Health Interview Survey (NHIS), and to analyze these self-reported pains by gender and age for Non-Hispanic (NH) Whites (Caucasians), Hispanics, and NH Blacks (African Americans). METHODS: Data from the 2000-2005 NHIS included information on gender, age, race, ethnicity, education, different common types of pain (specifically TMJMD-type, severe headache/migraine, neck, and low back pains), changes in health status, and health care utilization. Estimates and test statistics (ie, Pearson correlations, regressions, and logistic models) were conducted using SAS survey analysis and SUDAAN software that take into account the complex sample design. RESULTS: A total of 189,977 people (52% female and 48% males, 73% NH Whites, 12% Hispanic, 11% NH Blacks, and 4% "Other") were included. A total of 4.6% reported TMJMD-type pain, and only 0.77% overall reported it without any comorbid headache/migraine, neck, or low back pains; also 59% of the TMJMD-type pain (n = 8,964) reported ⋝ two comorbid pains. Females reported more comorbid pain than males (odds ratio [OR] = 1.41, P < .001); Hispanic and NH Blacks reported more than NH Whites (OR = 1.56, P <.001; OR= 1.38, P <.001, respectively). In addition, 53% of those with TMJMD-type pain had severe headache/migraines, 54% had neck pain, 64% low back pain, and 62% joint pain. Differences in gender and race by age patterns were detected. For females, headache/migraine pain with TMJMD-type pain peaked around age 40 and decreased thereafter regardless of race/ethnicity. Neck pain continued to increase up to about age 60, with a higher prevalence for Hispanic women at younger ages, and more pronounced in males, being the highest in the non-Whites. Low back pain was higher in Black and Hispanic females across the age span, and higher among non-White males after age 60. Joint pain demonstrated similar patterns by race/ethnicity, with higher rates for Black females, and increased with age regardless of gender. CONCLUSION: TMJMD-type pain was most often associated with other common pains, and seldom existed alone. Two or more comorbid pains were common. Gender, race, and age patterns for pains with TMJMD-type pain resembled the specific underlying comorbid pain.

Delivering Anticipatory Guidance About Technology Use to Adolescents in Primary Care: Rates in a Representative California Sample.

PURPOSE: This study aimed to investigate rates of anticipatory guidance about technology use in primary care, as recommended by the American Academy of Pediatrics Bright Futures Guidelines, in a representative sample of California adolescents. METHODS: Adolescents 12-17 years of age were interviewed as part of the California Health Interview Survey, the largest state health surveillance survey in the U.S. Participants who reported seeing a doctor for a physical examination or checkup in the prior year were asked if their doctor had talked to them about technology use. RESULTS: Overall, 29.7% of the 742 participants reported that their doctor talked to them about technology use. There were no statistically significant differences in rates by age, sex, race/ethnicity, household income, or family type. CONCLUSIONS: While the American Academy of Pediatrics recommends that providers deliver anticipatory guidance about technology use to adolescents in primary care, less than one-third of adolescents surveyed reported having conversations about this topic with their doctor. Given concerns about potential impacts of technology use on adolescent health, medical education should facilitate provider screening and counseling of adolescents about technology use in primary care settings.

Monitoring Adolescents' Receipt of Time Alone From Two National Surveys.

PURPOSE: Despite professional endorsement and research supporting time alone with a clinician for adolescents, low rates and disparities persist. The purpose of the present analysis was to provide detailed monitoring of time alone estimates in two national surveys that assess time alone for adolescents aged 12-17 years: the National Survey of Children's Health (NSCH) and the Medical Expenditure Panel Survey (MEPS). METHODS: Time alone assessments in the NSCH and the MEPS have different definitions. The NSCH assessed time alone within the most recent preventive visit, and the MEPS assessed it within the most recent health care visit. We analyzed these within the subsample of 12- to 17-year-olds who had any past-year preventive visit: MEPS 2016-2017, n = 2,689; and NSCH 2016-2017, n = 24,085. We developed time alone estimates for full and subgroup samples and conducted multivariable logistic regressions to determine differences by age, sex, race/ethnicity, income, insurance, and region. RESULTS: Overall time alone receipt was 49% (NSCH) and 29% (MEPS). Overall rates are not comparable because their definitions differ. Some subgroup differences were similar across datasets: younger adolescents (p < .01) and females (p < .05) had lower rates. CONCLUSIONS: Among adolescents with a past-year preventive visit, time alone rates are low. Lower rates for females versus males and younger versus older adolescents persist. Detailed monitoring results can help to shape promising strategies including clinic-based interventions, such as provider training and educating parents, in efforts to improve the provision of time alone in clinical practice.

Young Adult Perspectives on COVID-19 Vaccinations.

PURPOSE: Young adults have the highest cumulative incidence of COVID-19 infection in the country. Using March 2021 Household Pulse Survey data, an ongoing, cross-sectional nationally representative survey, we examined U.S. young adult intention to accept COVID-19 vaccines. METHODS: Young adult (ages 18-25 years) Household Pulse Survey participants were queried on intention to receive a COVID-19 vaccine and related perspectives (N = 5,082). RESULTS: Most unvaccinated respondents (76%) indicated an intention to become vaccinated. The most frequently cited reasons for potentially rejecting vaccination included desire to wait and see if the vaccine is safe (56%); concerns over side effects (53%); and believing others are in greater need of the vaccine (44%). CONCLUSIONS: With 24% of young adults hesitant to accept a COVID-19 vaccine, public health interventions should target reasons for hesitancy, address concerns about safety and side effects, and underscore the importance of vaccinations for this population.

Higher-Calorie Refeeding in Anorexia Nervosa: 1-Year Outcomes From a Randomized Controlled Trial.

BACKGROUND AND OBJECTIVES: We recently reported the short-term results of this trial revealing that higher-calorie refeeding (HCR) restored medical stability earlier, with no increase in safety events and significant savings associated with shorter length of stay, in comparison with lower-calorie refeeding (LCR) in hospitalized adolescents with anorexia nervosa. Here, we report the 1-year outcomes, including rates of clinical remission and rehospitalizations. METHODS: In this multicenter, randomized controlled trial, eligible patients admitted for medical instability to 2 tertiary care eating disorder programs were randomly assigned to HCR (2000 kcals per day, increasing by 200 kcals per day) or LCR (1400 kcals per day, increasing by 200 kcals every other day) within 24 hours of admission and followed-up at 10 days and 1, 3, 6, and 12 months post discharge. Clinical remission at 12 months post discharge was defined as weight restoration (≥95% median BMI) plus psychological recovery. With generalized linear mixed effect models, we examined differences in clinical remission over time. RESULTS: Of 120 enrollees, 111 were included in modified intent-to-treat analyses, 60 received HCR, and 51 received LCR. Clinical remission rates changed over time in both groups, with no evidence of significant group differences (P = .42). Medical rehospitalization rates within 1-year post discharge (32.8% [19 of 58] vs 35.4% [17 of 48], P = .84), number of rehospitalizations (2.4 [SD: 2.2] vs 2.0 [SD: 1.6]; P = .52), and total number of days rehospitalized (6.0 [SD: 14.8] vs 5.1 [SD: 10.3] days; P = .81) did not differ by HCR versus LCR. CONCLUSIONS: The finding that clinical remission and medical rehospitalization did not differ over 1-year, in conjunction with the end-of-treatment outcomes, support the superior efficacy of HCR as compared with LCR.

Short-term Outcomes of the Study of Refeeding to Optimize Inpatient Gains for Patients With Anorexia Nervosa: A Multicenter Randomized Clinical Trial.

Importance: The standard of care for refeeding inpatients with anorexia nervosa, starting with low calories and advancing cautiously, is associated with slow weight gain and protracted hospital stay. Limited data suggest that higher-calorie refeeding improves these outcomes with no increased risk of refeeding syndrome. Objective: To compare the short-term efficacy, safety, and cost of lower-calorie vs higher-calorie refeeding for malnourished adolescents and young adults with anorexia nervosa. Design, Setting, and Participants: In this multicenter randomized clinical trial with prospective follow-up conducted at 2 inpatient eating disorder programs at large tertiary care hospitals, 120 adolescents and young adults aged 12 to 24 years hospitalized with anorexia nervosa or atypical anorexia nervosa and 60% or more of median body mass index were enrolled from February 8, 2016, to March 7, 2019. The primary analysis was a modified intent-to-treat approach. Interventions: Higher-calorie refeeding, beginning at 2000 kcal/d and increasing by 200 kcal/d vs lower-calorie refeeding, beginning at 1400 k/cal and increasing by 200 kcal every other day. Main Outcomes and Measures: Main outcomes were end-of-treatment outcomes; the primary end point of this trial will be clinical remission over 12 months. Short-term efficacy was defined a priori as time to restore medical stability in the hospital, measured by the following 6 indices: 24-hour heart rate of 45 beats/min or more, systolic blood pressure of 90 mm Hg or more, temperature of 35.6 °C or more, orthostatic increase in heart rate of 35 beats/min or less, orthostatic decrease in systolic blood pressure of 20 mm Hg or less, and 75% or more of median body mass index for age and sex. The prespecified safety outcome was incidence of electrolyte abnormalities; cost efficacy was defined as savings associated with length of stay. Results: Because 9 participants withdrew prior to treatment, the modified intention-to-treat analyses included 111 participants (93%; 101 females [91%]; mean [SD] age, 16.4 [2.5] years). Higher-calorie refeeding restored medical stability significantly earlier than lower-calorie refeeding (hazard ratio, 1.67 [95% CI, 1.10-2.53]; P = .01). Electrolyte abnormalities and other adverse events did not differ by group. Hospital stay was 4.0 days shorter (95% CI, -6.1 to -1.9 days) among the group receiving higher-calorie refeeding, which was associated with a savings of $19 056 (95% CI, -$28 819 to -$9293) in hospital charges per participant. Conclusions and Relevance: In the first randomized clinical trial in the US to compare refeeding approaches in patients with anorexia nervosa and atypical anorexia nervosa, higher-calorie refeeding demonstrated short-term efficacy with no increase in safety events during hospitalization. Trial Registration: ClinicalTrials.gov Identifier: NCT02488109.

Medical Vulnerability of Young Adults to Severe COVID-19 Illness-Data From the National Health Interview Survey.

PURPOSE: COVID-19 morbidity and mortality reports in the U.S. have not included findings specific to young adults. The Centers for Disease Control and Prevention provides a list of conditions and associated behaviors, including smoking, conferring vulnerability to severe COVID-19 illness regardless of age. This study examines young adults' medical vulnerability to severe COVID-19 illness, focusing on smoking-related behavior. METHODS: A young adult subsample (aged 18-25 years) was developed from the National Health Interview Survey, a nationally representative data set, pooling years 2016-2018. The medical vulnerability measure (yes vs. no) was developed, guided by the Centers for Disease Control and Prevention medical indicators. The estimates of medical vulnerability were developed for the full sample, the nonsmoking sample, and the individual risk indicators. Logistic regressions were conducted to examine differences by sex, race/ethnicity, income, and insurance. RESULTS: Medical vulnerability was 32% for the full sample and half that (16%) for the nonsmoking sample. Patterns and significance of some subgroup differences differed between the full and the nonsmoking sample. Male vulnerability was (33%) higher than female (30%; 95% CI: .7-.9) in the full sample, but lower in nonsmokers: male (14%) versus female (19%; 95% CI: 1.2-1.7). The white subgroup had higher vulnerability than Hispanic and Asian subgroups in both samples-full sample: white (31%) versus Hispanic (24%; 95% CI: .6-.9) and Asian (18%; 95% CI: .4-.5); nonsmokers: white (17%) versus Hispanic (13%; 95% CI: .06-.9) and Asian (10%; 95% CI: .3-.8). CONCLUSIONS: Notably, lower young adult medical vulnerability within nonsmokers versus the full sample underscores the importance of smoking prevention and mitigation.

Caregiver acceptability and preferences for early childhood caries preventive treatments for Hispanic children.

OBJECTIVE: The objective of this study was to determine caregiver treatment acceptability and preferences for five preventive dental treatments for early childhood caries in young Hispanic children. METHODS: We interviewed 211 parents/caregivers of Hispanic children attending Head Start programs regarding their acceptability of, and preferences for, five standard preventive dental treatments for young children. Treatments assessed were toothbrushing with fluoride toothpaste, fluoride varnish, and xylitol in food for children, and xylitol gum and chlorhexidine rinse for mothers. The interview assessment included presentation of illustrated cards with verbal description of treatment, photograph/video clip, and treatment samples. Parents rated the acceptability of each treatment (1-5 scale) and treatment preferences within each of 10 possible pairs. Individual treatment preferences were summed to create overall preference scores (range 0-4). RESULTS: All treatments were rated as highly acceptable, however, there were differences (range 4.6-4.9; Friedman chi-square = 23.4, P < 0.001). Chlorhexidine, toothbrushing, and varnish were most acceptable, not different from each other, but more acceptable than xylitol in food (P < 0.05). Summed treatment preferences revealed greater variability (means ranged 1.4-2.6; Friedman chi-square = 128.2, P < 0.001). Fluoride varnish (2.6) and toothbrushing (2.5) were most highly preferred, and differences between preferences for xylitol in food (1.4), xylitol gum (1.5), and chlorhexidine (2.1) were all significant (P < 0.001). Preferences for chlorhexidine were also significantly greater than those for the xylitol products (P < 0.001). CONCLUSIONS: All five treatments were highly acceptable, however, when choosing among treatments overall, fluoride varnish and toothbrushing were favored over other treatments.

Developing an acceptability assessment of preventive dental treatments.

OBJECTIVES: Early childhood caries (ECC) is very prevalent among young Hispanic children. ECC is amenable to a variety of preventive procedures, yet many Hispanic families underutilize dental services. Acceptability research may assist in health care planning and resource allocation by identifying patient preferences among efficacious treatments with the goal of improving their utilization. The purposes of this study were (a) to develop a culturally competent acceptability assessment instrument, directed toward the caregivers of young Hispanic children, for five preventive dental treatments for ECC and (b) to test the instrument's reliability and validity. METHODS: An instrument of five standard treatments known to prevent ECC was developed, translated, reviewed by focus groups, and pilot tested, then tested for reliability The instrument included illustrated cards, brief video clips, and samples of the treatments and was culturally appropriate for low-income Hispanic caregivers. In addition to determining the acceptability of the five treatments individually, the treatments were also presented as paired comparisons. RESULTS: Focus groups and debriefing interviews following the pilot tests established that the instrument has good face validity. The illustrated cards, product samples, and video demonstrations of the five treatments resulted in an instrument possessing good content validity. The instrument has good to excellent test-retest reliability, with identical time 1-time 2 responses for each of the five treatments 92 percent of the time (range 87 to 97 percent), and the same treatment of the paired comparisons preferred 75 percent of the time (range 61 to 90 percent). CONCLUSIONS: The acceptability instrument described is reliable and valid and may be useful in program planning efforts to identify and increase the utilization of preferred ECC preventive treatments for target populations.

Young Adult Preventive Healthcare: Changes in Receipt of Care Pre- to Post-Affordable Care Act.

PURPOSE: Young adults have unique health and health care needs. Although morbidity and mortality stem largely from preventable factors, they lack a structured set of preventive care guidelines. The Affordable Care Act (ACA), enacted in 2010, increased young adult insurance coverage, prohibited copayments for preventive visits among privately insured and for many preventive services. The objectives were to evaluate pre- to post-ACA changes in young adults' past-year well visits and, among those using a past-year health care visit, the receipt of preventive services. METHODS: We used pooled Medical Expenditure Panel Survey data, comparing pre-ACA (2007-2009, N = 10,294) to post-ACA (2014-2016, N = 10,567) young adults aged 18-25 years. Bivariable and multivariable stratified logistic regression, adjusting for sociodemographic covariates, were conducted to determine differences in well visits and in preventive services among past-year health care utilizers: blood pressure and cholesterol checks, influenza immunization, and all three received. RESULTS: Past-year well visits increased from pre-ACA (28%) to post-ACA (32%), p < .001. Increases were noted for most demographic subgroups with greatest increases among males, Asian, and highest income subgroups. Larger pre- to post-ACA increases were found for most of the preventive services, p < .05, including the receipt of all three services (7% vs. 16%), p < .001, among past-year health care utilizers. CONCLUSION: Following ACA implementation, young adults experienced modest increases in well visit rates and larger increases in most preventive services received. Overall rates of both remain low. Building on these improvements requires concerted efforts that account for young adults' unique combination of health care issues and challenges in navigating an adult health care system.

Weight Loss and Illness Severity in Adolescents With Atypical Anorexia Nervosa.

BACKGROUND: Lower weight has historically been equated with more severe illness in anorexia nervosa (AN). Reliance on admission weight to guide clinical concern is challenged by the rise in patients with atypical anorexia nervosa (AAN) requiring hospitalization at normal weight. METHODS: We examined weight history and illness severity in 12- to 24-year-olds with AN (n = 66) and AAN (n = 50) in a randomized clinical trial, the Study of Refeeding to Optimize Inpatient Gains (www.clinicaltrials.gov; NCT02488109). Amount of weight loss was the difference between the highest historical percentage median BMI and admission; rate was the amount divided by duration (months). Unpaired t tests compared AAN and AN; multiple variable regressions examined associations between weight history variables and markers of illness severity at admission. Stepwise regression examined the explanatory value of weight and menstrual history on selected markers. RESULTS: Participants were 16.5 ± 2.6 years old, and 91% were of female sex. Groups did not differ by weight history or admission heart rate (HR). Eating Disorder Examination Questionnaire global scores were higher in AAN (mean 3.80 [SD 1.66] vs mean 3.00 [SD 1.66]; P = .02). Independent of admission weight, lower HR (ß = -0.492 [confidence interval (CI) -0.883 to -0.100]; P = .01) was associated with faster loss; lower serum phosphorus was associated with a greater amount (ß = -0.005 [CI -0.010 to 0.000]; P = .04) and longer duration (ß = -0.011 [CI -0.017 to 0.005]; P = .001). Weight and menstrual history explained 28% of the variance in HR and 36% of the variance in serum phosphorus. CONCLUSIONS: Weight history was independently associated with markers of malnutrition in inpatients with restrictive eating disorders across a range of body weights and should be considered when assessing illness severity on hospital admission.

Association Between Adolescent Preventive Care and the Role of the Affordable Care Act.

Importance: Despite decades of adolescent preventive well visit and services promotion (Guidelines for Adolescent Preventive Services and Bright Futures), rates are below recommended levels and little is known of the effect of the Patient Protection and Affordable Care Act (ACA) implementation on these care rates. Objectives: To use Medical Expenditure Panel Survey data to determine (1) whether adolescent well visit rates increased from the pre-ACA period to post-ACA period, and (2) whether caregivers' reports of past-year preventive services delivery increased from the pre- to post-ACA period among adolescents with any past-year health care visit. Design, Setting, and Participants: Secondary data analysis of 2007-2009 (before ACA implementation) and 2012-2014 (after ACA implementation) Medical Expenditure Panel Survey data on the differences in well visits and preventive services. Data were collected through computer-assisted personal interviews of caregivers of a nationally representative sample of a noninstitutionalized US population (n = 25 695 10- to 17-year-old adolescents). Main Outcomes and Measures: For objective 1, pre- to post-ACA period differences in past-year well visits: (1) stratified bivariable logistic regressions identifying subgroup rate differences and (2) multivariable analyses controlling for demographic factors. For objective 2, pre- to post-ACA period differences in caregiver reports of preventive services receipt, including time alone with clinician: (1) bivariable (year differences) and (2) multivariable logistic regressions controlling for demographic variables. Results: A total of 6279 (50.9%) and 6730 (50.8%) participating adolescents in the pre- and post-ACA period data were male, respectively. Under objective 1, we found that well-visit rates increased from 41% to 48% post-ACA implementation (odds ratio, 1.3; 95% CI, 1.2-1.5); minority and low-income groups had the greatest increases. Under objective 2, we found that among those with any past-year visit, most preventive services rates (8 of 9) increased post-ACA implementation (range, 2%-9%, absolute), with little or no change when controlling for demographic variables. Time alone with clinicians increased 1%, significant only when covariates were controlled (adjusted odds ratio, 1.2; 95% CI, 1.0-1.3). Conclusions and Relevance: Despite modest to moderate increases, with greatest gains for underserved youth, adolescent preventive care rates remain low, highlighting the need for increased efforts to bring adolescents into well care and improve clinician delivery of preventive care within their practices.

Increasing Delivery of Preventive Services to Adolescents and Young Adults: Does the Preventive Visit Help?

PURPOSE: Despite decades of emphasizing the delivery of adolescent preventive care visits and evidence that many preventive services reduce risk, little evidence links preventive visits to increased preventive service delivery. This study examined whether a preventive healthcare visit versus any nonpreventive healthcare visit was associated with higher rates of adolescent and young adult preventive services. METHODS: Analyzed Medical Expenditure Panel Survey data (2013-2015) to determine whether those with a preventive versus nonpreventive healthcare visit had higher rates of past-year preventive services receipt; adolescents (N = 8,474, ages 10-17) and young adults (N = 5,732, ages 18-25). Bivariable and multivariable analyses adjusting for personal/sociodemographic covariates tested for differences in preventive services rates between preventive versus nonpreventive care groups. Adolescent services were blood pressure, height and weight measured, and all three measured; and guidance given regarding healthy eating, physical activity, seatbelts and helmets, secondhand smoke, dental care, all six topics received, and time alone with provider. Young adult services were blood pressure and cholesterol checked, received influenza immunization, and all three services received. RESULTS: All preventive services rates were significantly higher in those attending preventive visits versus those with nonpreventive visits. Adolescent services increase ranged from 7% to 19% and young adults increase from 9% to 14% (all bivariable and multivariable analyses, p < .001). However, most rates were low overall. CONCLUSIONS: Higher rates of preventive services associated with preventive visits support its clinical care value. However, low preventive services rates overall highlight necessary increased efforts to promote preventive care and improve the provider delivery of prevention for both age groups.
