Insights
In 2001, most U.S. children had good health, but 10% lacked health insurance and 5% had no regular doctor. Asthma, learning disabilities, and Attention Deficit Hyperactivity Disorder (ADHD) affected many children.
Area of Science:
- Pediatric Health Statistics
- Public Health Surveillance
- Child Health Outcomes
Background:
- The National Health Interview Survey (NHIS) is a key source of U.S. child health data.
- Understanding child health disparities is crucial for public health initiatives.
Purpose of the Study:
- To present 2001 NHIS statistics on child health measures.
- To analyze health data by demographic and socioeconomic factors.
Main Methods:
- Utilized data from the 2001 National Health Interview Survey (NHIS).
- Collected information via face-to-face interviews with proxy respondents for children.
- Survey data is representative of the U.S. civilian noninstitutionalized population.
Main Results:
- 84% of children under 18 reported excellent or very good health.
- 10% of children lacked health insurance; 5% had no usual source of health care.
- Prevalence rates included asthma (13%), learning disability (8%), and Attention Deficit Hyperactivity Disorder (ADHD) (6%).
Conclusions:
- Despite overall good health, significant portions of children faced challenges with health insurance and access to care.
- Specific conditions like asthma, learning disabilities, and ADHD were prevalent in U.S. children.
- Children in single-mother families showed higher emergency room utilization compared to those in two-parent families.
Objectives:
This report presents statistics from the 2001 National Health Interview Survey (NHIS) on selected health measures for children under 18 years of age, classified by sex, age, race, Hispanic origin, family structure, parent's education, family income, poverty status, health insurance coverage, residence, region, and health status. The topics covered are asthma, allergies, learning disability, Attention Deficit Hyperactivity Disorder (ADHD), prescription medication, respondent-assessed health status, school-loss days, usual place of health care, time since last contact with a health care professional, unmet dental need, time since last dental contact, and selected measures of health care access.
Source Of Data:
The NHIS is a multistage probability sample survey conducted annually by interviewers of the U.S. Census Bureau for the Centers for Disease Control and Prevention, National Center for Health Statistics, 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 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.
Selected Highlights:
In 2001, most U.S. children under 18 years of age enjoyed excellent or very good health (84%). However, 10% had no health insurance coverage, and 5% had no usual place of health care. Thirteen percent of children had ever been diagnosed with asthma. Eight percent of children 3-17 years of age had a learning disability, and 6% of children had ADHD. 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 families.
