Child injury is a significant global health issue that contributes to both morbidity and mortality in children. Children with developmental disabilities are at a high risk for injuries due to a combination of environmental barriers and health conditions. However, little research has assessed the prevalence of injuries among this population in China.

Background: Due to a more stringent disability definition used for eligibility redetermination at age 18, individuals with disabilities may lose eligibility for the Supplement and Nutrition Assistance Program (SNAP).

Objective: This study examines how the transition to adulthood may affect the association between food security and self-rated health and healthcare needs for individuals with disabilities.

Methods: The study uses five years of data (2011-2015) from the National Health Interview Survey (NHIS).

Background: Pre-ACA, less than 6% of children with disabilities were uninsured, compared with more than 42% of young adults with disabilities ages 19-25. Individuals with disabilities face greater barriers to health care access upon transition into adulthood.

Objectives: We examined whether the ACA dependent coverage provision and Medicaid expansion improved the transition from pediatric to adult healthcare systems by reducing the gap in insurance coverage and access to care between teens and young adults with disabilities.

Introduction: This study examines how the transition to adulthood may affect food security for individuals with disabilities and estimates the effects of SNAP participation on their food security during the transition.

Methods: The study uses a repeated cross-sectional design with five years of data (2011-2015) from the National Health Interview Survey (NHIS) in the US. The difference-in-difference approach is applied to compare individuals with and without disabilities regarding their food security status in adolescence and young adulthood.

Beginning in 2010 the Affordable Care Act (ACA) allowed young adults (ages 19-25) to remain on their parents' private health insurance plans, even if they were not full-time students. This study investigated the impact of the ACA on health insurance coverage for young adults with disabilities, comparing their experience with that of young adults without disabilities and that of a group of older adults (ages 26-34) with disabilities. We analyzed the periods 2006-09 and 2011-14, which were before and after implementation of the dependent coverage provision in the ACA, respectively.

Having a child with a disability is considered a barrier to self-sufficiency among welfare recipients. This study examines the impact of children's educational disability on single-mother families' welfare exits and re-entries for a cohort of children in a metropolitan region in Missouri, who were born between 1982 and 1994, and received AFDC/TANF at least once from 1990 through 2008 (N=4,928). A semiparametric proportional hazards model for recurrent events is used to analyze the relationship between a child's educational disability and family welfare exit and re-entry.

Objective: We examined key factors that affect out-of-pocket medical expenditures per $1000 of household income for children with special health care needs (CSHCN) with a broad range of conditions, controlling for insurance type and concentrating on the potentially moderating role of the medical home.

Methods: A Heckman selection model was used to estimate whether the medical home influenced out-of-pocket medical costs per $1000 of household income for children covered by either private or public health insurance. Data from the 2005-2006 National Survey of CSHCN (N = 31,808) were used.

Objective: The purpose of this study was to examine the prevalence of unmet mental health needs in children identified by parents as having long-term emotional and behavioral problems, to identify the characteristics of these children, and to evaluate the influence of health insurance status and type on the odds of reporting unmet mental health needs.

Methods: We used the National Survey of Children with Special Health Care Needs (NSCSHCN) to estimate the prevalence of unmet mental health needs among children with long-term emotional/behavioral conditions. Using logistic regression models, we also assessed the independent impact of insurance status and type on unmet needs.

Objectives: We examined the association between several variables and the use of specialist physician services, developmental therapies, and prescription medications among children with special health care needs (N=38866).

Methods: We used a bivariate probit model to estimate whether a given child needed specialized services and whether that child accessed those services; we controlled for activity limitations and severity of special needs. Variables included family income, mother's (or other caregiver's) educational level, health insurance coverage, and perceived need for specialized services.

This study presents data from the first large-scale longitudinal study to track the involvement of children reported for maltreatment in both the special education and child welfare systems. A range of state and local administrative databases were combined and cross-sector service histories were established for 7,940 children who had received Aid to Families With Dependent Children between 1993 and 1994. The authors address the following questions: (a) Is maltreatment associated with entry into special education after controlling for other factors? (b) among maltreated children, does maltreatment type or child welfare service use predict special education eligibility? and (c) what is the relationship between maltreatment type and type of educational disability? Results indicate that child maltreatment system involvement generally predates special education entry and is predictive of entry even after controlling for other factors.
