Adolescents are particularly vulnerable to engaging in poor skin-protection behaviors. The objective of this study was to examine use of sunscreen and indoor tanning devices among a nationally representative sample of high school students during a 10-year period (2001–2011) using data from the Youth Risk Behavior Surveillance System. The percentage of youth who reported using sunscreen declined from 67.7% in 2001 to 56.1% in 2011. The prevalence of using indoor tanning devices was highest among white females: 37.4% in 2009 and 29.3% in 2011. These findings indicate the need for prevention efforts aimed at adolescents to reduce risks for skin cancer.

Lower levels of physical activity among rural relative to urban residents have been suggested as an important contributor to rural–urban health disparity; however, empirical evidence is sparse.

To improve surveillance of vaccine-preventable diseases, like measles, mumps, and rubella, CDC uses advanced molecular detection (AMD).

CDC's Advanced Molecular Detection (AMD) initiative will enhance the ability of CDC and its state and local partners to determine what types of foods and activities make people ill from foodborne diseases.
