Sociodemographic, health care, family, and community attributes have been associated with increased risk for mental, behavioral, and developmental disorders (MBDDs) in children (1,2). For example, poverty has been shown to have adverse effects on cognitive, socio-emotional, and physical development (1). A safe place to play is needed for gross motor development, and accessible health care is needed for preventive and illness health care (3). Positive parenting and quality preschool interventions have been shown to be associated with prosocial skills, better educational outcomes, and fewer health risk behaviors over time (2). Protective factors for MBDDs are often shared (4) and conditions often co-occur; therefore, CDC considered MBDDs together to facilitate the identification of factors that could inform collaborative, multidisciplinary prevention strategies. To identify specific factors associated with MBDDs among U.S. children aged 2–8 years, parent-reported data from the most recent (2011–2012) National Survey of Children’s Health (NSCH) were analyzed. Factors associated with having any MBDD included inadequate insurance, lacking a medical home, fair or poor parental mental health, difficulties getting by on the family’s income, employment difficulties because of child care issues, living in a neighborhood lacking support, living in a neighborhood lacking amenities (e.g., sidewalks, park, recreation center, and library), and living in a neighborhood in poor condition. In a multivariate analysis, fair or poor parental mental health and lacking a medical home were significantly associated with having an MBDD. There was significant variation in the prevalence of these and the other factors by state, suggesting that programs and policies might use collaborative efforts to focus on specific factors. Addressing identified factors might prevent the onset of MBDDs and improve outcomes among children who have one or more of these disorders.
NSCH is a cross-sectional, nationally representative, random-digit–dialed telephone survey that collects information about U.S. children aged <18 years. The survey includes indicators of child health and well-being, access to quality health care, family characteristics, and school and neighborhood environment.* Participating parents or guardians completed interviews about one randomly selected child (N = 95,677) per household. The interview completion rates were 54.1% and 41.2% for landline and cell phone samples, respectively; the overall response rate was 23.0%.† Data were weighted to account for unequal probability of selection of each household and child and for nonresponse. Weighted estimates reflect the population of noninstitutionalized children in the United States and within each state.
Parents were asked, “Has a doctor or other health care provider ever told you that [child] had [specified disorder]?” A child was considered to have an MBDD if the parent or guardian reported any of the following: attention-deficit/hyperactivity disorder (ADHD), depression, anxiety problems, behavioral or conduct problems such as oppositional defiant disorder or conduct disorder, Tourette syndrome, autism spectrum disorder, learning disability, intellectual disability, developmental delay, or speech or other language problems.
Analyses were restricted to the 35,121 U.S. children aged 2–8 years (defined by Healthy People 2020 as “early childhood”) with data for sex and each disorder. Weighted prevalence estimates of having any MBDD, and the associations with sociodemographic, health care, family, and community factors were calculated using statistical software to account for the complex sampling. Given previously documented associations between health care, family, and community factors, an exploratory regression model was also fit to determine which of the health care, family, or community factors that were independently associated with any MBDD remained significant after adjusting for the others. Sociodemographic factors were not included in the model.
Overall, among U.S. children aged 2–8 years, 15.4% had at least one diagnosed MBDD, by parent report (Table 1). Sociodemographic factors associated with report of having an MBDD included male sex, older age (aged 4–5 or 6–8 years compared with 2–3 years), being non-Hispanic white, and living in a household with a higher poverty level (i.e., <200% of federal poverty level) or where English was the primary language spoken.
Specific factors most strongly associated with MBDDs in early childhood were fair or poor parental mental health, difficulty getting by on the family’s income, child care problems (among parents of children aged 2–3 years), and lacking a medical home. Factors with the highest prevalence among children with MBDDs included lacking a medical home, living in a neighborhood lacking am
nities, difficulty getting by on family income, and living in a neighborhood in poor condition. When adjusted for the other significant health care, family, and community factors, an exploratory multivariate model showed that only lacking a medical home and fair or poor parental mental health remained significantly associated with having an MBDD (Table 2).
The prevalence of MBDDs and health care, family, and community factors among U.S. children aged 2–8 years varied by state (supplemental table at http://stacks.cdc.gov/view/cdc/38108). Prevalence of having any disorder varied from 10.6% in California to 21.5% in Arkansas and Kentucky. More than 90% of children received preventive care (i.e., parent or guardian reported that in the past 12 months, the child saw a health care provider for preventive medical care such as a physical exam or well-child checkup at least once) in each state.
Among health care factors, inadequate insurance was highest in South Carolina (26.5%), and lacking a medical home was highest in Arizona (52.2%); Vermont had the lowest prevalence of both inadequate insurance (14.7%) and lacking a medical home (27%).
The prevalences of difficulty getting by on the family’s income and child care problems were both highest in Arizona (34.9% and 21.8%, respectively); income difficulties were lowest in North Dakota (18.5%), whereas child care problems were lowest in Nevada (2.6%§). Fair or poor parental mental health prevalence was highest in the District of Columbia (19.1%) and lowest in Kansas (6.9%).
The District of Columbia had the highest prevalence of living in a neighborhood in poor condition (46.2%) but the lowest prevalence of living in a neighborhood without all of the reported amenities (26.7%); the lowest prevalence of living in a neighborhood in poor condition was 20% in Maryland, whereas the highest prevalence of living in a neighborhood without all of the reported amenities was 67.5% in Mississippi (67.5%). Finally, reported prevalence of lack of neighborhood support was highest in Arizona (32.9%) and lowest in North Dakota (7.9%).
Discussion
Mental, behavioral, and developmental disorders identified in childhood often persist into adulthood and are associated with increased risk for poorer school outcomes and employment opportunities, other adverse health conditions, earlier mortality, and considerable costs for persons with the disorders, their families, and society (2). Children are more likely to outgrow speech or language problems or certain developmental delays than other MBDDs, particularly if they receive early intervention. In other disorders such as Tourette syndrome, some children might outgrow the condition by late adolescence but remain at increased risk for other disorders that are more likely to persist, including ADHD and obsessive-compulsive disorder. MBDDs can substantially affect health care, families, and communities. Children with MBDDs often require more health and therapy services than children without MBDDs. Families might face stress associated with the disorder itself or financial stress associated with treatment of the disorder. Communities might need to provide additional services and support for both children and families and might face lower productivity if the parent or guardian is unable to work (2). Thus, efforts to prevent the onset of MBDDs and to improve their identification and treatment in early childhood might improve health and well-being throughout the lifespan, with the potential to translate into cost savings and overall population health improvements (2).
The data in this report included a number of sociodemographic factors associated with MBDDs, including poverty and living in a primarily English-speaking household. Household language might be reflective of increased access to health care (and thus increased likelihood of being diagnosed) or the level of acculturation, a factor that has been associated with risk behaviors and poorer health outcomes in some domains (5). The identified health care, family, and community factors associated with child MBDDs in this report have each previously been documented to be associated with poverty (6). Each significant factor might reflect the effect of insufficient parental and community resources to support optimal child development and might contribute to chronic stress. Chronic stress in early childhood can impact lifelong health. A chronically activated physiologic stress response impacts the sympathetic nervous system, metabolism, and the brain, resulting in increased risk for high blood pressure, obesity, inflammatory diseases, and mental and behavioral disorders (1). The prevalences of both poverty and MBDDs have been increasing among U.S. children,¶ underscoring the need for public health strategies to prevent and treat MBDDs (7).
The factors most strongly associated with MBDDs in early childhood were lacking a medical home, fair or poor parental mental health, and difficulty getting by on the family’s income. These and the other factors varied widely by state and might inform state-level decisions regarding allocation of resources to improve early childhood health at the population level. Strategies that address socioeconomic (e.g., poverty) and community (e.g., neighborhood condition) factors form the foundation of the health impact pyramid framework where interventions have the greatest public health impact (8), including demonstrated impacts into adulthood, and are likely to be cost-effective (2,9,10). Further analyses are needed to identify which factors might be the most effective targets to promote children’s health.
Because a large percentage of children were reported to receive preventive care, pediatric clinical settings might be one venue for identifying and possibly delivering services to children and families in need. For example, the American Academy of Pediatrics has published policy statements on screening for postpartum depression (e.g., one way to address poor maternal mental health), the medical home, recognizing social determinants of health, and partnering with public health to address child health from a population perspective (3). Increased awareness of the association of these factors with MBDDs by agencies serving children, (e.g., health departments, schools, and community organizations) might improve referrals and stimulate partnerships to address early childhood health within established community settings (3).
The findings in this report are subject to at least five limitations. First, the presence of MBDDs was based on parent report and might be subject to recall error or bias. Second, children with undiagnosed disorders were not included, and therefore, state estimates of these disorders might vary both by presence of disorders and likelihood of identification. Similarly, state data on health care, family, and community factors might be influenced by prevalence of MBDDs. Third, the cross-sectional nature of the data and reliance on parent report prevented drawing conclusions about the direction of the associations or about causality. Fourth, although the data were weighted for nonresponse, bias related to nonresponse might remain given the low response rate. Finally, a wide range of disorders were included and might be differentially related to health care, family, and community factors, and also likely vary in the extent to which they can be prevented.
These data support the Institute of Medicine recommendation that resources directed toward improving health care and supporting families and communities are needed to prevent mental, emotional, and behavioral disorders, and promote healthy development among all young children (2). Such investments would require substantial collaboration across public health, pediatric, and other agencies responsible for providing services to children, but could yield widespread benefits for early childhood and lifelong health (8).
