America's Children: Data on Child Well-Being, 2010
Learn more about the most recently available major federal statistics on children and youth in these areas: family and social environment, economic circumstances, health care, physical environment and safety, behavior, education, and health.
This feature highlights data from the Physical Environment and Safety section of America's Children in Brief: the percentage of children with specified blood cotinine levels during selected years from 1988 to 2008. Continine, a breakdown product of nicotine, is a marker for recent exposure to secondhand smoke. As the number of public places allowing smoking has declined, so has the percentage of children with detectable blood continine levels.3 In 2007–2008, 53 percent of children ages 4–11 had detectable blood continine levels (at or above 0.05 ng/mL), down from 64 percent in 1999–2000 and 88 percent in 1988–1994. The percentage of children with blood continine levels above 1.0 ng/mL, which indicates high levels of secondhand smoke exposure at home or other places, declined from 26 percent in 1988–1994 to 18 percent in 1999–2000.4 The percentage did not change significantly from 1999–2000 to 2007–2008.
America's Children In Brief: Key National Indicators of Well-Being, 2010 was compiled by the Federal Interagency Forum on Child and Family Statistics, a working group of 22 federal agencies that collect, analyze, and report data on issues related to children and families. The report groups the most recently available major federal statistics on children and youth under several domains: family and social environment, economic circumstances, health care, physical environment and safety, behavior, education, and health. The purpose of the report is to provide statistical information on children and families in a nontechnical, easy-to-use format in order to stimulate discussion among data providers, policymakers, and members of the public.
Children's exposure to indoor air pollutants can have a substantial impact on their health.1 Exposure to secondhand smoke increases the probability of lower respiratory tract infections, asthma, other respiratory conditions, and sudden infant death syndrome (SIDS).2
NOTE: "Any detectable continine" indicates blood continine levels at or above 0.05 nanograms per milliliter (ng/mL), the detectable level of continine in the blood in 1988–1994. continine levels are reported for nonsmoking children only. The average (geometric mean) blood continine level in children living in homes where someone smoked was 1.0 ng/mL in 1988–1994 and in 2003–2006.
