Insights
In 1998, most U.S. children had good health, but 12% lacked health insurance and 6% had no regular doctor. Asthma, learning disabilities, and Attention Deficit Disorder affected millions of kids.
Area of Science:
- Pediatric Health Statistics
- Public Health Surveillance
- Childhood Health Disparities
Background:
- The National Health Interview Survey (NHIS) provides crucial data on the health of U.S. children.
- Understanding children's health status is vital for public health policy and resource allocation.
Purpose of the Study:
- To present 1998 statistics on selected health measures for U.S. children under 18.
- To analyze health data by demographic and socioeconomic factors, including insurance, family structure, and health conditions.
Main Methods:
- Utilized data from the 1998 National Health Interview Survey (NHIS).
- NHIS is a representative multistage probability sample survey of the U.S. civilian noninstitutionalized population.
- Data collected via face-to-face interviews with proxy respondents for children.
Main Results:
- 84% of U.S. children under 18 reported excellent or very good health in 1998.
- 12% of children were uninsured, and 6% lacked a usual source of medical care.
- Prevalence estimates included 12% ever diagnosed with asthma, 8% with learning disabilities, and 6% with Attention Deficit Disorder (ADD).
Conclusions:
- Despite overall good health, significant portions of children lacked health insurance and consistent medical care access.
- Children in single-mother families showed higher emergency room utilization compared to those in two-parent or single-father families.
- Findings highlight persistent disparities in child health and healthcare access in the U.S.
Objectives:
This report presents statistics from the 1998 National Health Interview Survey (NHIS) on selected health measures for children under 18 years of age, classified by sex, age, race/ethnicity, family structure, parent's education, family income, poverty status, health insurance coverage, place of residence, region, and current health status. The topics covered are asthma, allergies, learning disabilities, Attention Deficit Disorder, use of medication, respondent-assessed health status, school-loss days, usual place of medical care, time since last contact with a health care professional, selected health care risk factors, and time since last dental contact.
Source Of Data:
The NHIS is a multistage probability sample survey conducted annually by interviewers of the U.S. Census Bureau for the National Center for Health Statistics, Centers for Disease Control and Prevention, and is representative of the civilian noninstitutionalized population of the United States. Data are collected during face-to-face interviews with adults present at the time of interview. Information about children is collected for one randomly selected child per family in face-to-face interviews with an adult proxy respondent familiar with the child's health.
Highlights:
In 1998 most U.S. children under 18 years of age enjoyed excellent or very good health (84%). However, 12% of children had no health insurance coverage, and 6% of children had no usual place of medical care. Twelve percent of children had ever been diagnosed with asthma. An estimated 8% of children 3-17 years of age had a learning disability, and an estimated 6% of children had Attention Deficit Disorder (ADD). Lastly, 11% of children in single mother families had two or more visits to an emergency room in the past year compared with 6% of children in two-parent or single-father families.
