Incidence of pediatric narcolepsy diagnosis and management: evidence from claims data.

STUDY OBJECTIVES: To characterize the incidence of pediatric narcolepsy diagnosis, subsequent care, and potential sociodemographic disparities in a large US claims database. METHODS: Merative MarketScan insurance claims (n=12,394,902) were used to identify youth (6-17 years) newly diagnosed with narcolepsy (ICD-10 codes). Narcolepsy diagnosis and care 1-year post-diagnosis included polysomnography (PSG) with Multiple Sleep Latency Test (MSLT), pharmacological care, and clinical visits. Potential disparities were examined by insurance coverage and child race and ethnicity (Medicaid-insured only). RESULTS: The incidence of narcolepsy diagnosis was 10:100,000, primarily type 2 (69.9%). Most diagnoses occurred in adolescents with no sex differences, but higher rates in Black versus White youth with Medicaid. Two-thirds had a prior sleep disorder diagnosis and 21-36% had other co-occurring diagnoses. Only half (46.6%) had a PSG with MSLT (± 1-year post-diagnosis). Specialty care (18.9% pulmonary, 26.9% neurology) and behavioral health visits were rare (34.4%), although half were prescribed stimulant medications (51.0%). Medicaid-insured were 86% less likely than commercially insured youth to have any clinical care and 33% less likely to have a PSG with MSLT. CONCLUSIONS: Narcolepsy diagnoses occurred in 0.01% of youth, primarily during adolescence, and at higher rates for Black versus White children with Medicaid. Only half had evidence of a diagnostically required PSG with MSLT, underscoring potential misdiagnosis. Many patients had co-occurring conditions, but specialty and behavioral health care were limited. Results suggest misdiagnosis, underdiagnosis, and limited narcolepsy treatment, as well as possible insurance-related disparities. Results highlight the need to identify determinants of evidence-based pediatric narcolepsy diagnosis and management.

Caregiver Preferences for Primary Care Clinic-Based Food Assistance: A Discrete Choice Experiment.

OBJECTIVE: The American Academy of Pediatrics recommends that pediatric providers screen families for food insecurity and connect them to appropriate resources. However, it is unclear how clinics can best provide families with resources consistent with their needs and preferences. In this study, we elicited caregiver preferences for clinic-based food assistance. METHODS: We conducted a cross-sectional discrete choice experiment in which caregivers at 2 pediatric primary care clinics were asked to choose between hypothetical food programs. Programs varied across 4 categories: 1) resources provided (eg, food delivery, food in clinic, assistance enrolling in benefits); 2) support staff providing resources (eg, social worker, community health worker, physician, or nurse); 3) outreach modality (eg, phone, email, text); and 4) outreach frequency. Multinomial logistic regression was used to assess caregiver preferences within each category and the relative importance of each category to caregiver decisions. RESULTS: We surveyed 142 caregivers who were predominantly Black (87%) and Medicaid-insured (90%). Caregiver preferences for food programs were most strongly influenced by the food resources provided. Caregivers preferred food delivery over other forms of food supports, such as food provided in clinic. They preferred assistance from a benefits enrollment specialist, community health worker, or social worker to assistance from a physician or nurse. CONCLUSIONS: Pediatric clinics serving families at risk of food insecurity should use caregiver preferences to inform the design of family-centered interventions. Clinics should consider connecting caregivers with food delivery programs, and pediatric payors should adopt reimbursement models that support multidisciplinary team-based care to address food insecurity.

Communication and Birth Experiences Among Black Birthing People Who Experienced Preterm Birth.

PURPOSE: Physically or psychologically distressing birth experiences can influence postpartum health, parenting efficacy, and future pregnancy plans. Communication deficits contribute to negative birth experiences. This qualitative analysis explored themes related to communication and negative birth experiences among Black birthing people who experienced preterm birth. METHODS: We conducted qualitative interviews with non-Hispanic Black, English language-proficient birthing people with Medicaid-insured preterm infants. Interviews were designed to explore experiences with health care access and well-being after birth. Interviews were audio recorded, transcribed, and coded following an integrated approach where we applied a priori codes and captured emergent themes from the data. RESULTS: We interviewed 30 participants from October 2018 to July 2021. Median gestational age at birth was 30 weeks (range 22-36 weeks). Interviews occurred a median of 7 months postpartum (range 2-34 months). Themes emerged related to negative birth experiences and communication: (1) communication gaps during urgent or emergent intrapartum procedures contributed to negative birth experiences; (2) postpartum opportunities to share birth experiences, particularly with peers, sometimes mitigated the psychological consequences of negative birth experiences; (3) participants did not consistently discuss concerns about future pregnancy risk related to negative birth experiences with clinical teams. CONCLUSIONS: Themes from this sample of Black birthing people who experienced preterm birth suggest 3 ways health systems might intervene to improve communication to mitigate the consequences of negative birth experiences. Improvement efforts in these areas may improve postpartum health, future pregnancy outcomes, and long-term health.

Continuous Eligibility And Coverage Policies Expanded Children's Medicaid Enrollment.

We examined children's Medicaid participation during 2019-21 and found that as of March 2021, states newly adopting continuous Medicaid coverage for children during the COVID-19 pandemic experienced a 4.62 percent relative increase in children's Medicaid participation compared to states with previous continuous eligibility policies.

Trends and Persistent Disparities in Child Obesity During the COVID-19 Pandemic.

The COVID-19 pandemic has been associated with increases in pediatric obesity and widening pre-existing disparities. To better understand the pandemic's long-term impacts, we evaluated trends in obesity across different demographic groups during the pandemic through December 2022. Using a retrospective cohort design, we analyzed electronic health record data from a large pediatric primary care network. Logistic regression models fit using generalized estimating equations estimated odds ratios (ORs) for changes in the level and trajectory of obesity across 2-year month-matched periods: prepandemic (June 2017 to December 2019) and pandemic (June 2020 to December 2022). Among a cohort of 153,667 patients with visits in each period, there was a significant increase in the level of obesity at the pandemic onset [OR: 1.229, 95% confidence interval (CI): 1.211-1.247] followed by a significant decrease in the trend for obesity (OR: 0.993, 95% CI: 0.992-0.993). By December 2022, obesity had returned to prepandemic levels. However, persistent sociodemographic disparities remain.

A Qualitative Study of Perspectives of Black Women on Autonomy and Motivational Interviewing.

Purpose: Motivational interviewing (MI) is an evidence-based strategy to modify health behaviors, including some risk factors for adverse birth outcomes. Black women, who have disproportionately high rates of adverse birth outcomes, have reported mixed preferences on MI. This study explored the acceptability of MI among Black women who are at high risk for adverse birth outcomes. Methods: We conducted qualitative interviews with women with a history of preterm birth. Participants were English-language proficient and had Medicaid-insured infants. We purposively oversampled women whose infants had medical complexity. Interviews explored experiences with health care and health behaviors after birth. The interview guide was iteratively developed to obtain specific reactions to MI by including videos demonstrating MI-consistent and MI-inconsistent counseling. Interviews were audio recorded, transcribed, and coded following an integrated approach in which we applied a priori codes related to MI and allowed themes to emerge from the data. Results: We interviewed 30 non-Hispanic Black women from October 2018 to July 2021. Eleven viewed the videos. Participants emphasized the importance of autonomy in decision-making and health behavior. Participants expressed a preference for MI-consistent clinical approaches, including autonomy support and building rapport, considering them respectful, nonjudgmental, and likely to support change. Conclusions: In this sample of Black women with a history of preterm birth, participants valued an MI-consistent clinical approach. Incorporating MI into clinical care may improve the experience of health care among Black women, thus serving as one strategy to promote equity in birth outcomes.

Inequities in Time Spent Coordinating Care for Children and Youth With Special Health Care Needs.

OBJECTIVE: In the United States, caregivers of children and youth with special health care needs (CYSHCN) must navigate complex, inefficient health care and insurance systems to access medical care. We assessed for sociodemographic inequities in time spent coordinating care for CYSHCN and examined the association between time spent coordinating care and forgone medical care. METHODS: This cross-sectional study used data from the 2018-2020 National Survey of Children's Health, which included 102,740 children across all 50 states. We described the time spent coordinating care for children with less complex special health care needs (SHCN) (managed through medications) and more complex SHCN (resulting in functional limitations or requiring specialized therapies). We examined race-, ethnicity-, income-, and insurance-based differences in time spent coordinating care among CYSHCN and used multivariable logistic regression to examine the association between time spent coordinating care and forgone medical care. RESULTS: Over 40% of caregivers of children with more complex SHCN reported spending time coordinating their children's care each week. CYSHCN whose caregivers spent ≥ 5 h/wk on care coordination were disproportionately Hispanic, low-income, and publicly insured or uninsured. Increased time spent coordinating care was associated with an increasing probability of forgone medical care: 6.7% for children whose caregivers spent no weekly time coordinating care versus 9.4% for< 1 hour; 11.4% for 1 to 4 hours; and 15.8% for ≥ 5 hours. CONCLUSIONS: Reducing time spent coordinating care and providing additional support to low-income and minoritized caregivers may be beneficial for pediatric payers, policymakers, and health systems aiming to promote equitable access to health care for CYSHCN.

Access to What for Whom? How Care Delivery Innovations Impact Health Equity.

Achieving health equity (where every person has the opportunity to attain their full health potential) requires the removal of obstacles to health, including barriers to high-quality medical care. Innovations in service delivery can inadvertently maintain, worsen, or introduce inequities. As such, implementation of innovations must be accompanied by a dual commitment to evaluate impact on marginalized groups and to restructure systems that obstruct people from health and healthcare. Understanding the impact innovations have on access to high-quality care is central to this effort. In this Perspective, we join conceptual models of healthcare access and quality with health equity frameworks to conceptualize healthcare receipt as a series of interactions between people and systems unfolding over time. This synthesized model is applied to illustrate the effects of telemedicine on patient, population, and system outcomes. Telemedicine may improve or worsen health equity by altering access to care and by altering quality of care once it is accessed. Teasing out these varied effects is complex and requires considering multilevel influences on the outcome of a care-seeking episode. This synthesized model can be used to inform research, practice, and policy surrounding the equity implications of care delivery innovations more broadly.

Cost-effectiveness of a motivational interviewing obesity intervention versus usual care in pediatric primary care offices.

OBJECTIVE: This study aimed to assess the incremental cost-effectiveness ratio (ICER) of a 2-year motivational interviewing (MI) intervention versus usual primary care. METHODS: A national trial was implemented in the Pediatric Research in Office Settings (PROS) network of the American Academy of Pediatrics to evaluate MI versus usual care for children (2-8 years old; baseline BMI 85th-97th percentiles). Health care use, food costs, provider fees, and training costs were assessed, and sensitivity analyses were conducted. Primary outcome was the ICER, calculated as cost per unit change in BMI percentile for intervention versus usual care. RESULTS: At 2 years, 72% of enrolled parent/child dyads were retained; 312 children were included in the analysis. Mean BMI percentile point change was -4.9 and -1.8 for the intervention and control, respectively, yielding an incremental reduction of 3.1 BMI percentile points (95% CI: 1.2-5.0). The intervention cost $1051 per dyad ($658 for training DVD development). Incorporating health care and non-health care costs, the intervention ICER was $363 (range from sensitivity analyses: cost saving, $3159) per BMI percentile point decrease per participant over 2 years. CONCLUSIONS: Training pediatricians, nurse practitioners, and registered dietitians to deliver MI-based interventions for childhood obesity in primary care is clinically effective and acceptably cost-effective. Future work should explore this approach in broader dissemination.

Associations Between Food Insecurity and Neighborhood Safety, Social Cohesion, Social Control, and Crime Among Mothers of Preschool-Aged Children.

Food insecurity has myriad associations with poor health, and low-income communities have higher than average prevalence of food insecurity. Living in a supportive neighborhood social environment may protect against food insecurity, while adverse neighborhood social conditions, such as crime, may increase the likelihood of food insecurity. To examine associations between food insecurity and neighborhood social factors among families with young children, we administered a cross-sectional survey to 300 mothers and female caregivers of Medicaid-enrolled two- to four-year-old children in Philadelphia. We used multivariable regression to examine associations between food insecurity and perceived neighborhood safety, social cohesion, informal social control, and crime, adjusted for demographics, socioeconomic status, and neighborhood characteristics. Lower food insecurity prevalence was associated with higher perceived neighborhood safety and social cohesion, and lower police-recorded violent crime rates. Future work to increase food security among low-income households may benefit from targeting the neighborhood social environment.

Autism Spectrum Disorder Screening During the COVID-19 Pandemic in a Large Primary Care Network.

OBJECTIVE: To assess the impact of the COVID-19 pandemic on screening for autism spectrum disorder (ASD) and screening equity among eligible children presenting for well-child care in a large primary care pediatric network, we compared rates of ASD screening completion and positivity during the pandemic to the year prior, stratified by sociodemographic factors. METHODS: Patients who presented for in-person well-child care at 16 to 26 months between March 1, 2020 and February 28, 2021 (COVID-19 cohort, n = 24,549) were compared to those who presented between March 1, 2019 and February 29, 2020 (pre-COVID-19 cohort, n = 26,779). Demographics and rates of completion and positivity of the Modified Checklist for Autism in Toddlers with Follow-up (M-CHAT/F) were calculated from the electronic health record and compared by cohort using logistic regression models. RESULTS: Total eligible visits decreased by 8.3% between cohorts, with a greater decline in Black and publicly insured children. In the pre-COVID-19 cohort, 89.0% of eligible children were screened at least once, compared to 86.4% during the pandemic (P < 0.001). Significant declines in screening completion were observed across all sociodemographic groups except among Asian children, with the sharpest declines among non-Hispanic White children. Sociodemographic differences were not observed in screen-positive rates by cohort. CONCLUSIONS: Well-child visits and ASD screenings declined across groups, but with different patterns by race and ethnicity during the COVID-19 pandemic. Findings regarding screen-completion rates should not be interpreted as a decline in screening disparities, given differences in who presented for care. Strategies for catch-up screening for all children should be considered.

Association of Neighborhood Social Context and Perceived Stress Among Mothers of Young Children.

BACKGROUND: Chronic parental stress may negatively impact health among both parents and children. Adverse neighborhood social conditions like crime may increase stress while a supportive neighborhood may buffer stress and promote well-being. Our objective was to examine associations between neighborhood social factors and stress among mothers of young children. METHODS: We surveyed 300 mothers/female caregivers of Medicaid-enrolled 2 to 4-year-old children in Philadelphia. Maternal stress was measured via the 10-item Perceived Stress Scale (range 0-40). Mothers' perceived neighborhood safety and collective efficacy were assessed using validated scales. Addresses were geocoded to link census tract-level violent crime rates. We used multivariable linear regression to examine associations of neighborhood safety, collective efficacy, and crime with maternal stress, adjusted for demographics, household socioeconomic status, and neighborhood poverty. RESULTS: Among mothers (mean age 31, 60% Black/African American), higher perceived neighborhood safety and collective efficacy were associated with lower stress scores after adjustment for covariates. Each 1-point increase (on a 5-point scale) in perceived neighborhood safety was associated with a 2.30-point decrease in maternal stress (95% CI: -3.07, -1.53). Similarly, each 1-point increase in perceived collective efficacy was associated with a 3.08-point decrease in maternal stress (95% CI: -4.13, -2.02). Police-recorded violent crime rates were not associated with maternal stress. CONCLUSION: Mothers of young children who perceive their neighborhood social environment more favorably report less stress compared to those who feel their neighborhood environment is less safe and cohesive. Future work is warranted to investigate whether interventions that increase perceived neighborhood safety and collective efficacy reduce stress.

COVID-19 and Adolescent Depression and Suicide Risk Screening Outcomes.

BACKGROUND: Mental health concerns increased during the coronavirus disease 2019 pandemic, but previous studies have not examined depression screening in pediatric primary care. We aimed to describe changes in screening, depressive symptoms, and suicide risk among adolescents during the coronavirus disease 2019 pandemic. METHODS: In a repeat cross-sectional analysis of electronic health record data from a large pediatric primary care network, we compared the percentage of primary care visits where adolescents aged 12 to 21 were screened for depression, screened positive for depressive symptoms, or screened positive for suicide risk between June and December 2019 (prepandemic) and June and December 2020 (pandemic). Changes were examined overall, by month, and by sex, race and ethnicity, insurance type, and income. Modified Poisson regression was used to calculate prevalence ratios (PRs) for the prepandemic to pandemic changes. RESULTS: Depression screening at primary care visits declined from 77.6% to 75.8% during the pandemic period (PR: 0.98, 95% confidence interval [CI]: 0.90-1.06). The percentage of adolescents screening positive for depressive symptoms increased from 5.0% to 6.2% (PR: 1.24, 95% CI: 1.15-1.34), with greater increases among female, non-Hispanic Black, and non-Hispanic white adolescents. Positive suicide risk screens increased from 6.1% to 7.1% (PR: 1.16, 95% CI: 1.08-1.26), with a 34% relative increase in reporting recent suicidal thoughts among female adolescents (PR: 1.34, 95% CI: 1.18-1.52). CONCLUSIONS: Results suggest that depression and suicide concerns have increased during the pandemic, especially among female adolescents. Results underscore the importance of consistent depression and suicidality screening.

Association of WIC Participation and Electronic Benefits Transfer Implementation.

Importance: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is an important source of nutritional support and education for women and children living in poverty; although WIC participation confers clear health benefits, only 50% of eligible women and children currently receive WIC. In 2010, Congress mandated that states transition WIC benefits by 2020 from paper vouchers to electronic benefits transfer (EBT) cards, which are more convenient to use, are potentially less stigmatizing, and may improve WIC participation. Objective: To estimate the state-level association between transition from paper vouchers to EBT and subsequent WIC participation. Design, Setting, and Participants: This economic evaluation of state-level WIC monthly benefit summary administrative data regarding participation between October 1, 2014, and November 30, 2019, compared states that did and did not implement WIC EBT during this time period. Difference-in-differences regression modeling allowed associations to vary by time since policy implementation and included stratified analyses for key subgroups (pregnant and postpartum women, infants younger than 1 year, and children aged 1-4 years). All models included dummy variables denoting state, year, and month as covariates. Data analyses were performed between March 1 and June 15, 2020. Exposures: Statewide transition from WIC paper vouchers to WIC EBT cards, specified by month and year. Main Outcomes and Measures: Monthly number of state residents enrolled in WIC. Results: A total of 36 states implemented WIC EBT before or during the study period. EBT and non-EBT states had similar baseline rates of poverty and food insecurity. Three years after statewide WIC EBT implementation, WIC participation increased by 7.78% (95% CI, 3.58%-12.15%) in exposed states compared with unexposed states. In stratified analyses, WIC participation increased by 7.22% among pregnant and postpartum women (95% CI, 2.54%-12.12%), 4.96% among infants younger than 1 year (95% CI, 0.95%-9.12%), and 9.12% among children aged 1 to 4 years (95% CI, 3.19%-15.39%; P for interaction = .20). Results were robust to adjustment for state unemployment and poverty rates, population, and Medicaid expansion status. Conclusions and Relevance: In this study, the transition from paper vouchers to WIC EBT was associated with a significant and sustained increase in enrollment. Interventions that simplify the process of redeeming benefits may be critical for addressing low rates of enrollment in WIC and other government benefit programs.

Perspectives of Urban Adolescent Black Males and Their Parents on Well Care.

OBJECTIVE: Adolescents have fewer well-care visits than all other age groups. Males and ethnic minorities are seen least often. We elicited from Black adolescent males and their parents key drivers of teen well-care seeking. METHODS: We conducted separate semistructured interviews with Black adolescent males and their parents. We recruited parent-teen dyads from West Philadelphia. Eligible teens were age 13 to 18, with no complex chronic health conditions. We purposively sampled teens who had not received preventive care in at least 2 years, some of whom had since returned to care and some not. Interviews were recorded, transcribed, and coded by 2 coders using the constant comparative method, resolving discrepancies by consensus. Interviews continued until thematic saturation. RESULTS: We interviewed 23 Black adolescent males (mean age 15) and 22 parents (20 mothers). Participants understood that teens should routinely receive preventive care. Four themes emerged: receiving preventive care is important to knowing teens are mentally and physically well; remembering to schedule/attend visits is challenging - participants find appointment reminders helpful; mothers noted that males of all ages are generally disengaged from health care; teens and parents felt that a "good" parent ensures teens receive preventive care. CONCLUSIONS: Black adolescent males and their parents value regular preventive care as an opportunity to ensure the teen is physically and mentally well, but competing priorities interfere with care receipt. Results support testing the impact of reminders on receipt of care in this population. These reminders may be most effective if directed at mothers and focused on "good parenting."

The Future(s) of Pediatric Primary Care.

Pediatric primary care (PPC) arose in the early 20th century as the fusion of acute and chronic pediatric illness care with preventive elements borrowed from public and maternal and child health. Well-established and thriving by the 1930s, PPC saw major changes in childhood morbidity and mortality in the latter half of the 20th century with the recognition of the "new morbidity" of school, behavior, and social problems. At the same time, PPC experienced changes in its workforce, which became increasingly female and added nurse practitioners and physician assistants as practitioners. Independent practice, previously the dominant business model, decreased in prominence at the end of the 20th century as health systems bought practices and other sites morphed into federally qualified health centers. In the present century, electronic health records (EHRs) have brought profound changes in PPC workflows and practitioner experience. In addition, disruptive market competition such as retail clinics and corporate telemedicine providers coupled with changes in health insurance from fee-for-service to value-based payment further challenge the care model and economics of PPC. Finally, recognition of family social circumstances as major determinants of children's health presents another challenge to the status quo. As such, although one PPC future may resemble its present state, a more innovative future is likely to include clinics and practices more oriented toward and linked to communities and directed at the social determinants of health. In addition, the rise in physical, behavioral, and social problems in practice call for a growing focus on wellness, including sleep, nutrition, and activity, that promises to reorient the PPC future in productive new directions. The half-way technology of current EHR systems will ideally be spun into electronic hubs that facilitate teamwork between PPC, specialists, and community groups. Research and practice improvement strategies including involvement in "learning health systems" will be critical to making PPC effective in an evolving society. Although threatened by 21st century forces and hard-to-anticipate change, PPC is ideally positioned to build upon its core functions to create multidisciplinary teams that reach into the community, promoting a holistic wellness for children consistent with the broadest definition of health.

Reducing Antibiotic Prescribing in Primary Care for Respiratory Illness.

BACKGROUND: One-third of outpatient antibiotic prescriptions for pediatric acute respiratory tract infections (ARTIs) are inappropriate. We evaluated a distance learning program's effectiveness for reducing outpatient antibiotic prescribing for ARTI visits. METHODS: In this stepped-wedge clinical trial run from November 2015 to June 2018, we randomly assigned 19 pediatric practices belonging to the Pediatric Research in Office Settings Network or the NorthShore University HealthSystem to 4 wedges. Visits for acute otitis media, bronchitis, pharyngitis, sinusitis, and upper respiratory infection for children 6 months to <11 years old without recent antibiotic use were included. Clinicians received the intervention as 3 program modules containing online tutorials and webinars on evidence-based communication strategies and antibioti c prescribing, booster video vignettes, and individualized antibiotic prescribing feedback reports over 11 months. The primary outcome was overall antibiotic prescribing rates for all ARTI visits. Mixed-effects logistic regression compared prescribing rates during each program module and a postintervention period to a baseline control period. Odds ratios were converted to adjusted rate ratios (aRRs) for interpretability. RESULTS: Among 72 723 ARTI visits by 29 762 patients, intention-to-treat analyses revealed a 7% decrease in the probability of antibiotic prescribing for ARTI overall between the baseline and postintervention periods (aRR 0.93; 95% confidence interval [CI], 0.90-0.96). Second-line antibiotic prescribing decreased for streptococcal pharyngitis (aRR 0.66; 95% CI, 0.50-0.87) and sinusitis (aRR 0.59; 95% CI, 0.44-0.77) but not for acute otitis media (aRR 0.93; 95% CI, 0.83-1.03). Any antibiotic prescribing decreased for viral ARTIs (aRR 0.60; 95% CI, 0.51-0.70). CONCLUSIONS: This program reduced antibiotic prescribing during outpatient ARTI visits; broader dissemination may be beneficial.

Clustering of unhealthy behaviors in a nationally representative sample of U.S. children and adolescents.

Poor diet, low physical activity, sedentary behavior and smoking are modifiable risk factors for chronic diseases that often develop early in life. An improved understanding of how unhealthy behaviors co-occur within individual children across childhood and adolescence could inform the development of more effective prevention approaches. Using data from the 2011-2016 National Health and Nutrition Examination Survey, we calculated weighted prevalence of five unhealthy behaviors - excessive screen time, poor diet quality, low physical activity, fast food consumption, and smoking (adolescents only) - alone and in combination among U.S. children and adolescents, stratified by age group (2-5, 6-11, 12-15, and 16-19 years). Multivariable logistic regression was used to estimate associations between health behavior clustering (≥2 unhealthy behaviors) and sociodemographic characteristics by age group. Among 7714 children and adolescents, the most prevalent behaviors were excessive screen time and poor diet quality. Unhealthy behavior clustering increased significantly with age (from 29.0% for ages 2-5 to 73.9% for ages 16-19 years, p-trend: <0.0001). The most common health behavior combination was excessive screen time and poor diet (from 14.4% prevalence for ages 2-5 to 45.3% for ages 16-19 years). Smoking prevalence was low, but 97% of smokers had ≥1 other unhealthy behavior. Unhealthy behavior clustering was significantly more prevalent among black than white children (ages 2-5 and 6-11) and less prevalent among Hispanic older adolescents (age 16-19). Associations with household characteristics varied by age group. These results provide a population-level understanding of the extent to which unhealthy behaviors co-occur in U.S. children and adolescents.
