Prevalence of Self-Reported Physically Active Adults
United States, 2007
Under the new 2008 Physical Activity Guidelines for Americans, the minimum aerobic activity required to produce substantial health benefits in adults is 150 minutes of moderate-intensity activity per week, or 75 minutes of vigorous-intensity activity per week, or an equivalent combination. These recommendations differ from those used in
Healthy People 2010. When applied to self-reported data from 2007, 64.5% of respondents met the new guidelines, whereas 48.8% met the
Healthy People objectives.

Revised Surveillance Case Definitions for HIV Infection Among Adults, Adolescents, and Children Aged <18 Months and for HIV Infection and AIDS Among
Children Aged 18 Months to <13 Years
United States, 2008
For adults and adolescents (i.e., persons aged >13 years), the human immunodeficiency virus (HIV) infection classification system and the surveillance case definitions for HIV infection and acquired immunodeficiency syndrome (AIDS) have been revised and combined into a single case definition for HIV infection. The HIV infection case definition for children aged <13 years and the AIDS case definition for children aged 18 months to <13 years also have been revised. Laboratory-confirmed evidence of HIV infection is now required to meet the case definition among adults, adolescents, and children aged 18 months to <13 years. All states and territories should begin using the 2008 surveillance case definitions immediately.

Abortion Surveillance
United States, 2005
CDC began conducting abortion surveillance in 1969 to document the number and characteristics of women obtaining legal induced abortions. This report is based on abortion data for 2005, provided voluntarily to CDC’s National Center for Chronic Disease Prevention and Health Promotion, Division of Reproductive Health.
For 2005, CDC compiled data that were voluntarily provided from 49 reporting areas in the United States: 47 states (excluding California, New Hampshire, and Louisiana), the District of Columbia (DC), and New York City (NYC). Legal induced abortion was defined as a procedure, performed by a licensed physician or someone acting under the supervision of a licensed physician, that was intended to terminate a suspected or known intrauterine pregnancy and to produce a nonviable fetus at any gestational age. The total number of legal induced abortions was available from all reporting areas; however, not all of these areas collected data on some or all characteristics of women who obtained abortions, and the availability of such data varied by reporting area. Abortion data were compiled using suggested table shells that were sent to the reporting areas. Not all reporting areas used the suggested tables.
