TL;DR: For instance, the authors found that 63.0% of the US adult population in 2003 reported ever going online, with 63.7% (95% CI, 61.7%-65.8%) of the online population having looked for health information for themselves or others at least once in the previous 12 months.

TL;DR: The prevalence of diabetes continues to increase rapidly in the U.S. and will become even more common because the prevalence of obesity is also rising, and major efforts are needed to alter these trends.

TL;DR: Self-reports are reasonably accurate for certain chronic conditions and for routine screening exams and can provide a useful estimate for broad measures of population prevalence.

TL;DR: Examination of 31-year trends in CVD risk factors by annual income and educational levels among US adults found education- and income-related disparities have worsened for smoking, and increases in diabetes prevalence have occurred primarily among persons with a lower socioeconomic status.

TL;DR: The overall slowing rate of decline in smoking prevalence since 1985 may indicate success of increased tobacco advertising and promotional activities targeted at adolescents or inadequate antitobacco education efforts.
