Percentage of Women Who Gained <15 Pounds During Pregnancy, by Age Group and Race/Ethnicity of Mother --- United States, 2005		3/21/2008
The recommended amount of weight gain during pregnancy is based on a woman's height and prepregnancy weight. Maternal weight gain of <15 pounds is not recommended for women having a singleton birth, regardless of the woman's height and prepregnancy weight. Inadequate weight gain has been associated with an increased risk for intrauterine growth retardation, low birthweight, and perinatal mortality. In 2005, overall, 10% of mothers of term singletons gained <15 pounds. Differences by age and race/ethnicity were substantial. For all racial/ethnic groups, inadequate weight gain increased with age. Non-Hispanic black women of all ages were more likely than non-Hispanic white and Hispanic women to gain <15 pounds during pregnancy.

Mean Gestational Age, by Plurality --- United States, 2005		3/07/2008
Shorter gestation is associated with poorer birth outcomes, long-term morbidity, and higher infant mortality rates. The risk for shorter gestation is greater with multiple births than singleton births. In 2005, the mean gestational age for singletons was 38.7 weeks, compared with 35.2 weeks for twins, 31.9 weeks for triplets, 29.8 weeks for quadruplets, and 27.4 weeks for quintuplets and higher.

The level among men decreased from 203 mg/dL to 195 mg/dL and among women decreased from 205 to 201 mg/dL. The Healthy People 2010 objective to reduce mean serum cholesterol levels among adults to <200 mg/dL (objective 12-14) was met in 2005--2006 for the overall adult population aged >20 years and for men but not for women.

Percentage of Women Who Gained >40 Pounds During Pregnancy, by Race/Ethnicity of Mother --- United States, 1990, 2000, and 2005		2/08/2008
Since 1989, data on weight gain of women during pregnancy have been collected on U.S. birth certificates. Weight gain of >40 pounds during pregnancy is not recommended for women having a singleton birth, regardless of the woman's height and prepregnancy weight. Excessive weight gain is associated with greater risk for gestational diabetes, preeclampsia, and other adverse conditions during pregnancy and complications of delivery for both mother and infant. From 1990 to 2005, the percentage of women overall who gained >40 pounds increased from 15% to 20%; the percentage who gained >40 pounds also increased among non-Hispanic white, non-Hispanic black, and Hispanic women. Non-Hispanic white women were more likely than non-Hispanic black and Hispanic women to gain >40 pounds during pregnancy in 1990, 2000, and 2005.

Estimated Percentage of Office-Based Physicians Using Selected Electronic Medical Record (EMR) Features --- National Ambulatory Medical Care Survey, United States, 2006		2/01/2008
In 2006, approximately 29.2% of office-based physicians reported that they used an EMR system, and use of specific EMR features varied substantially. EMR features providing clinical reminders for guideline-based interventions or screening tests (13.1%) and public health reporting (6.6%) were used less than other features. Only 12.4% of physicians used EMR systems with all four of the features considered necessary for a minimally functional system (i.e., systems allowing for computerized orders for prescriptions, computerized orders for tests, electronic viewing of test results, and electronic viewing of clinical notes).

In 2004, the majority (63%) of nursing homes reported <60% employees had received an influenza shot last influenza season. In 2004, nursing homes used different strategies to promote influenza vaccination among employees. Three of these strategies (offering free vaccinations, furloughing employees with influenza-like illness, and requiring proof of vaccination) were significantly associated with staff influenza vaccination rates >60%. Only 1% of surveyed facilities did not use at least one of the strategies.

Spina Bifida and Anencephaly Rates --- United States, 1991, 1995, 2000, and 2005		1/11/2008
Neural tube defects (NTDs) are serious birth defects of the brain (anencephaly) and spine (spina bifida). Since 1992, a national health recommendation has called for women of childbearing age in the United States to consume 400 µg of folic acid daily to reduce their risk for having a pregnancy affected by NTDs. The spina bifida rate per 100,000 live births declined 25% from 1995 to 2000 and 13% from 2000 to 2005. The anencephaly rate declined 36% from 1991 to 1995 and was unchanged from 1995 to 2005. http://www.cdc.gov/nchs/deaths.htm.

Life Expectancy at Birth, by Race and Sex --- United States, 1970--2005		1/04/2008

During 2003--2005, Puerto Rican children overall had a higher prevalence of asthma than Mexican-American, non-Hispanic white, and non-Hispanic black children. Differences in poverty status did not explain the disparities for Puerto Rican and non-Hispanic black children, two populations that had higher asthma rates than non-Hispanic white and Mexican-American children regardless of poverty status. The reason for the higher rate among Puerto Rican children overall is unknown.

Prevalence of Selected Unhealthy Behavior Characteristics Among Adults Aged >18 Years, by Race --- National Health Interview Survey, United States, 2002–2004		2/02/2007
The percentage of adults with selected unhealthy behavior characteristics varied by race during 2002–2004. Blacks and Asians had the lowest prevalence of consuming five or more alcoholic drinks in a single day; Asians also had the lowest prevalence of current cigarette smoking and obesity. AIAN had among the highest prevalences of consuming five or more drinks, current smoking, and obesity. Generally, physical inactivity was the most prevalent unhealthy behavior.

Percentage of Total Births That Were Preterm, by Gestational Age --- United States, 1990 and 2005		1/19/2007
The proportion of total births that were preterm increased from 9.7% in 1990 to 11.0% in 2005. Most of the increase was among births occurring at 34--36 weeks (i.e., late preterm), which increased from 6.8% to 8.1%. Although late preterm infants are at lower risk for mortality and long-term morbidity than other preterm infants, they are at higher risk than those born later in pregnancy.

Birth Rates Among Females Aged 15--19 Years, by State --- United States, 2004		1/05/2007
Age of mother is a predictor of maternal and infant health risk. Pregnant teens aged 15--19 years are less likely to receive timely prenatal care and gain appropriate weight and more likely to smoke during pregnancy than pregnant women aged >20 years. These factors are associated with poor birth outcomes. For example, infants born to mothers who smoke during pregnancy are 65% more likely to have low birthweight and 70% more likely to die in infancy than infants born to nonsmokers. In 2004, the overall U.S. birth rate for mothers aged 15--19 years was 41.1 births per 1,000 females in that age group. Among states, rates ranged from 62.6 (Texas) to 18.2 (New Hampshire).

Age-Adjusted Death Rates for Leading Causes of Injury Death, by Year --- United States, 1979--2004		12/22/2006

In 2004, for the first time since 1968, when such data first became available, the number of reported poisoning deaths (30,308) and the age-adjusted poisoning death rate (10.3 per 1000,000 population) exceeded the number of firearm deaths (29,569) and the firearm death rate (10.0), respectively. During 1999--2004, the poisoning death rate increased 45%, whereas the firearm death rate declined 3%; during the same period, no change occurred in the rate (14.7) for motor-vehicle traffic deaths.

Reasons for No Health Insurance Coverage Among Uninsured Persons Aged <65 Years --- National Health Interview Survey, United States, 20		12/15/2006
Overall, approximately 17% (41 million) of persons aged <65 years had no health insurance at the time of interview. Of these, approximately one half did not have coverage because of cost, and one fourth did not have coverage because of loss of a job or a change in employment. Approximately 14% of uninsured persons did not have coverage because their employer did not offer it or the insurance company refused coverage, and 10% did not have coverage because of cessation of Medicaid benefits. Less than 3% of persons without health insurance did not have coverage because of a change in marital status or death of a parent.

Percentage of Men Aged >40 Years with Prostate-Specific Antigen (PSA) Levels of >2.5 and >4.0 ng/mL, by Race/Ethnicity --- National Health and Nutrition Examination Survey, United States, 2001--2004		12/08/2006
Although screening for prostate cancer using the PSA test is common, clinicians are divided over whether the screening test is effective and whether a lower PSA threshold should be used to refer patients for prostate biopsy to rule out cancer. A PSA level of >4.0 ng/mL is the common threshold; however, certain researchers have recommended lowering the level to >2.5 ng/mL. During 2001--2004, approximately 6.2% (3.6 million)of men aged >40 years in the United States had a PSA level of >4.0 ng/mL, and approximately 13.1% had a PSA of >2.5 ng/mL. Differences among racial/ethnic groups tested were not statistically significant.

During 2000--2004, American Indian/Alaska Native (AI/AN) adults were most likely to have self-assessed symptoms of serious psychological distress, and Asian adults were least likely. Overall, the percentage was highest for AI/AN women, who were at least twice as likely as white women and black women and nearly four times as likely as Asian women to have self-assessed symptoms of serious psychological distress. AI/AN men were more than three times as likely as Asian men to have symptoms.

Percentage of Older Adults Who Engaged in Regular Leisure-Time Physical Activity, by Age Group and Sex --- United States, 2000--2003		7/21/2006
During 2000--2003, men aged >55 years were more likely than women in the same age group to engage in regular leisure-time physical activity. For both men and women, prevalence of regular activity was nearly the same for adults aged 55--64 and 65--74 years, declined among those aged 75--84 years, and declined further among those aged >85 years. Among adults aged >85 years, approximately one in 10 men and one in 20 women engaged in regular leisure-time physical activity.

Percentage Change in Death Rates for the Leading Causes of Unintentional Injury, by Mechanism of Injury --- United States, 1999--2003		6/30/2006
During 1999--2003, unintentional injury mortality increased 5.4%. Increases in mortality rates from motor vehicle traffic, poisoning, and fall exceeded declines in mortality rates from suffocation/choking, fire/burn, and drowning. The 0.7% increase in the motor vehicle injury rate resulted from a 50.0% increase in motorcycle-related injury.

Infant Mortality Rates, by Maternal Race/Ethnicity --- United States, 1995 and 2003		6/23/2006
Infant mortality rates decreased significantly (p<0.05, z test) in the United States from 1995 to 2003.

Percentage of Persons Aged 18--49 Years with HIV Infection, by Age Group and Race/Ethnicity --- United States, 1999--2002		6/02/2006
During 1999--2002, the seroprevalence of HIV was 0.37% among persons aged 18--39 years and 0.54% among persons aged 40--49 years. Among persons aged 18--49 years, the highest percentage of HIV infection (3.58%) was among non-Hispanic blacks aged 40--49 years. These prevalences likely are underestimates of HIV infection because the survey sample is the U.S. household population and excluded homeless persons and those in institutions, who might be at higher risk for infection.

Since 1993--1994, the annual number of OPD visits increased by 39% to approximately 90 million during 2003--2004. Although the majority (80%) of OPD patients were seen by a physician during 2003--2004, the role of mid-level providers (e.g., physician assistants, nurse practitioners, and midwives) became more prominent. Since 1993--1994, the percentage of visits in which only a mid-level provider was seen increased from approximately 6% to 11%. During the same period, the percentage of visits in which both a mid-level provider and physician were seen did not change, and the percentage of visits in which only a physician was seen decreased by 4%, from 81% to 78%.

Health-Care Visits for Asthma, by Medical Setting and Health-Insurance Status --- United States, 2003		4/14/2006
The type of medical setting in which persons receive health care for asthma differs for those with private health insurance and those without health insurance. Approximately 30% of medical visits for asthma by persons without health insurance occurred in emergency departments, compared with only 6% of visits by those with private insurance. Asthma is a condition considered to be sensitive to effective primary care and, if controlled, would result in fewer visits to the emergency department.

Percentage of Hospital Emergency Departments (EDs) Having to Divert Ambulances, by Selected Characteristics --- United States, 20		4/72006
Ambulance diversion occurs when EDs are too crowded to handle any more critically ill or injured patients and request that ambulances bypass them for another hospital. In 2003, an estimated 45% of hospital EDs were on diversion status at some time during the previous year. Ambulance diversions were more common in EDs with larger volumes of patients and those in metropolitan areas.

Percentage of U.S.-Born and Foreign-Born Adults Aged >18 Years Reporting Selected Health Risk Factors and Conditions -- United States, 1998--2003		3/24/2006
During 1998--2003, the prevalence of obesity, smoking, hypertension, and cardiovascular disease was greater among U.S.-born adults than foreign-born adults. The foreign-born population was younger, less likely to have a high school diploma, more likely to be poor, and had less access to health care. During 1970---2002, the number of foreign-born persons in the United States increased more than threefold to 32.5 million, or 11.5% of the total U.S. population.

Total Fertility Rates, by State --- United States, 2003		12/16/2005
On the basis of 2003 birth rates, U.S. women have an average of 2.0 births during their lives. The total fertility rate (i.e., the estimated average number of births per woman in a lifetime, based on the age-specific birth rates observed in a given year) varies by state, ranging from 1.7 in Vermont to 2.6 in Utah. In 2003, the District of Columbia had the lowest rate at 1.6. Rates were lower in the northeastern states and higher in the southwestern states.
