Objective: This report presents national estimates of contraceptive use and method choice based on the 1982, 1995, and 2002 National Surveys of Family Growth (NSFG). It also presents data on where women obtained family planning and medical services, and some of the services that they received.

Methods: Data were collected through in-person interviews with 12,571 men and women 15-44 years of age in the civilian noninstitutional population of the United States in 2002. This report is based on the sample of 7,643 women interviewed in 2002. The response rate for women in the study was about 80 percent.

Results: The leading method of contraception in the United States in 2002 was the oral contraceptive pill, used by 11.6 million women; the second leading method was female sterilization, used by 10.3 million women. The condom was the third-leading method, used by about 9 million women and their partners. The condom is the leading method at first intercourse; the pill is the leading method among women under 30; and female sterilization is the leading method among women 35 and older. More than 98 percent of women 15-44 years of age who have ever had sexual intercourse with a male (referred to as "sexually experienced women") have used at least one contraceptive method. Over the 20 years from 1982 to 2002, the percent who had ever had a partner who used the male condom increased from 52 to 90 percent. The proportion who had ever had a partner who used withdrawal increased from 25 percent in 1982 to 56 percent in 2002. Another important measure of contraceptive use is use at the first premarital intercourse: before 1980, only 43 percent of women (or their partner) used a method of birth control at their first premarital intercourse. By 1999-2002, the proportion using a method at first premarital intercourse had risen to 79 percent.

This report presents the prevalence of the leading types of dietary supplements taken during the third National Health and Nutrition Examination Survey (NHANES III), 1988-94. Approximately 40 percent of the U.S. population 2 months of age and older reported taking some type of dietary supplement in NHANES III, and the leading supplements taken were multivitamin/multiminerals (22 percent), multivitamins plus vitamin C (15 percent), vitamin C as a single vitamin (13 percent), other dietary supplements such as herbal and botanical supplements (7 percent), and vitamin E as a single vitamin (6 percent). To some extent, the leading types of supplements and order changed after stratifying the results by sex and age groups. Other major contributors were multivitamins with iron or fluoride taken by children, iron taken by adolescent and young adult females, and calcium taken by middle-aged and elderly females. There was also a high prevalence of use of potassium among middle-aged and elderly adults but this probably reflects its use as a medication rather than as a dietary supplement. Collecting information on dietary supplement use is an important part of monitoring the nutritional status of the U.S. population.

This report presents dietary intake estimates for fats and fatty acids from the National Health and Nutrition Examination Survey, 1999-2000, for the U.S. population. These include: total fat; total saturated, monounsaturated, and polyunsaturated fat; individual fatty acids; and cholesterol. Fat intakes are estimated from one 24-hour dietary recall interview. Population means, medians, and standard errors of the mean are weighted to produce national estimates and are presented by sex and age groups. Assessment of dietary intakes is an important part of monitoring the nutritional status of the U.S. population.

This report presents trends in national estimates of mean weight, height, and body mass index (BMI) from the National Health Examination and the National Health and Nutrition Examination Surveys between 1960 and 2002. The tables included in this report present data for adults by sex, race/ethnicity, and age group and for children by sex and year of age. Mean weight and BMI have increased for both sexes, all race/ethnic groups, and all ages. Among adults, mean weight increased more than 24 pounds. Although not as dramatically, mean height has also increased for most ages and for both males and females.

Objective: This report describes ambulatory care visits made to physician offices in the United States. Statistics are presented on selected characteristics of the physician's practice, the patient, and the visit. This report also highlights visits to primary care specialties.

Methods: The data presented in this report were collected from the 2002 National Ambulatory Medical Care Survey (NAMCS). NAMCS is a part of the ambulatory care component of the National Health Care Survey that measures health care utilization across various types of providers. NAMCS is a national probability sample survey of visits to office-based physicians in the United States. Sample data are weighted to produce annual national estimates. Selected trends from 1992, 1993, 1995, and 1997 are also presented.

Results: During 2002, an estimated 890 million visits were made to physician offices in the United States, an overall rate of 314.4 visits per 100 persons. From 1992 through 2002, the visit rate for persons 45 years of age and over increased by 14%, from 407.3 to 465.8 visits per 100 persons. The visit rate to physician offices in metropolitan statistical areas (MSAs) (337.3 visits per 100 persons) was significantly larger than the rate in non-MSAs (221.9 visits per 100 persons). For one-half of all office visits, regardless of specialty, physicians indicated they were the patient's primary care physician (PCP). Of the visits to physicians other than the patient's PCP, about one-third (31.1 percent) were referrals. New patients, representing 12.1 percent of the visits in 2002, are down 18% since 1992. Primary care specialists provided 90 percent of all preventive care visits. Essential hypertension, acute upper respiratory infection, diabetes mellitus, and arthropathies were the leading illness-related primary diagnoses. There were an estimated 104.0 million injury-related visits in 2002, or 36.7 visits per 100 persons. On average, 2.3 medications were ordered or provided at each office visit with any mention of a medication. The leading therapeutic class for drugs mentioned at office visits included nonsteroidal anti-inflammatory drugs (NSAIDs) (4.9 mentions per 100 visits) and antidepressants (4.5 mentions per 100 visits). Of primary care specialists, 25.8 percent reported not accepting new patients who are Medicaid enrollees.

Objective: This report presents national estimates on access to health care for five subgroups of Hispanic/Latino children in the United States: Mexican, Puerto Rican, Cuban, Central or South American, and other Hispanic. For comparison, estimates are also presented for non-Hispanic white children.

Methods: Data for persons of all ages in the U.S. civilian noninstitutionalized population are collected each year in the National Health Interview Survey (NHIS), which is conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. Each year, data are collected for approximately 100,000 persons in 40,000 households. In the 1998-2001 surveys combined, 53,510 interviews (14,284 Hispanic/Latino children) were completed by knowledgeable adults for a subsample of children under age 18 years, with an overall response rate of 80.2%.

Results: Each year, an estimated 3.0 million (25.7%) Hispanic/Latino children lacked health insurance coverage at the time of interview, 1.6 million (14.1%) had no usual place to go for health care during the past year, and 1.4 million (17.6%) experienced unmet health care needs during the past year due to cost. Of the five Hispanic/Latino subgroups, Mexican children were most likely (30.4%) to lack health insurance coverage, followed by Central or South American children (23.8%) and other Hispanic children (18.6%). The percentage of children having a usual place to go for health care was highest for Cuban children (93.5%) and lowest for Mexican children (83.3%). The percentage of children who experienced unmet medical needs due to cost in the past year was 18.3% for Mexican children, 16.3% for Puerto Rican children, 12.8% for Central or South American children, and 8.3% for Cuban children. Lack of access to health care was most prevalent among Hispanic/Latino children who had poor or near poor poverty status, whose parents had less than a high school diploma, and who were foreign born.

Conclusion: Access to health care varied among subgroups of Hispanic/Latino children. Understanding subgroup differences may help community-based programs improve access to care among Hispanic/Latino children.

Objective: This report presents selected estimates of complementary and alternative medicine (CAM) use among U.S. adults, using data from the 2002 National Health Interview Survey (NHIS), conducted by the Centers for Disease Control and Prevention's (CDC) National Center for Health Statistics (NCHS).

Methods: Data for the U.S. civilian noninstitutionalized population were collected using computer-assisted personal interviews (CAPI). This report is based on 31,044 interviews of adults age 18 years and over. Statistics shown in this report were age adjusted to the year 2000 U.S. standard population.

Results: Sixty-two percent of adults used some form of CAM therapy during the past 12 months when the definition of CAM therapy included prayer specifically for health reasons. When prayer specifically for health reasons was excluded from the definition, 36% of adults used some form of CAM therapy during the past 12 months. The 10 most commonly used CAM therapies during the past 12 months were use of prayer specifically for one's own health (43.0%), prayer by others for one's own health (24.4%), natural products (18.9%), deep breathing exercises (11.6%), participation in prayer group for one's own health (9.6%), meditation (7.6%), chiropractic care (7.5%), yoga (5.1%), massage (5.0%), and diet-based therapies (3.5%). Use of CAM varies by sex, race, geographic region, health insurance status, use of cigarettes or alcohol, and hospitalization. CAM was most often used to treat back pain or back problems, head or chest colds, neck pain or neck problems, joint pain or stiffness, and anxiety or depression. Adults age 18 years or over who used CAM were more likely to do so because they believed that CAM combined with conventional medical treatments would help (54.9%) and/or they thought it would be interesting to try (50.1%). Most adults who have ever used CAM have used it within the past 12 months, although there is variation by CAM therapy.

Objectives: This report presents national estimates of the use of non-Federal short-stay hospitals in the United States during 2002 and trend data for selected variables. Numbers and rates of discharges, diagnoses, and procedures are shown by age and sex. Average lengths of stay are presented for all discharges and for selected diagnostic categories by age and sex.

Methods: The estimates are based on medical abstract data collected through the 2002 National Hospital Discharge Survey. The survey has been conducted annually since 1965 by the National Center for Health Statistics. Diagnoses and procedures presented are coded using the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM).

Results: Trends in the utilization of non-Federal short-stay hospitals show that the average age and age distribution of inpatients has changed dramatically from 1970 through 2002. In 1970, the average age of all inpatients was 40.7 years compared with 52.1 years in 2002. The percent of discharges aged 65 years and over comprised 20 percent of hospital discharges in 1970 whereas they comprised 38 percent in 2002. During this same period, the percent of inpatients under 15 years of age declined from 13 to 8 percent and inpatients 15-44 years of age declined from 43 to 32 percent. The percent of inpatients aged 45-64 years was more stable during these 23 years. In 2002, there were an estimated 33.7 million hospital discharges, excluding newborn infants. The discharge rate was 1,174.6 per 10,000 population. The rate of respiratory disease diagnoses among persons 65 years and over was significantly higher than for other age groups and has risen since 1975. There were 42.5 million procedures performed on inpatients during 2002. About one-quarter of all procedures performed on females were obstetrical. Almost one-quarter of all procedures performed on males were cardiovascular.

This report presents dietary intake estimates for selected minerals from the National Health and Nutrition Examination Survey, 1999-2000, for the U.S. population. These minerals included: calcium, copper, iron, magnesium, phosphorus, potassium, selenium, sodium, and zinc. Mineral intakes are estimated from one 24-hour dietary recall interview. Population means, medians, and standard errors of the mean are weighted to produce national estimates, and are presented by sex and age groups. Assessment of dietary intakes is an important part of monitoring the nutritional status of the U.S. population.

Objectives: This report describes ambulatory care visits to hospital emergency departments (EDs) in the United States. Statistics are presented on selected hospital, patient, and visit characteristics. Selected trends in ED utilization from 1992 through 2002 are also presented.

Methods: The data presented in this report were collected from the 2002 National Hospital Ambulatory Medical Care Survey (NHAMCS). NHAMCS is part of the ambulatory care component of the National Health Care Survey that measures health care utilization across various types of providers. NHAMCS is a national probability sample survey of visits to emergency and outpatient departments of non-Federal, short-stay, and general hospitals in the United States. Sample data are weighted to produce annual national estimates.

Results: During 2002, an estimated 110.2 million visits were made to hospital EDs, about 38.9 visits per 100 persons. From 1992 through 2002, an increasing trend in the ED utilization rate was observed for persons over 44 years of age. In 2002, abdominal pain, chest pain, fever, and cough were the leading patient complaints accounting for nearly one-fifth of all visits. Acute upper respiratory infection was the leading illness-related diagnosis at ED visits. From 1992 through 2002, decreases in ED visit rates were observed for intracranial injuries in children, and increases were found for depression in young adults and arthropathies among middle-aged and elderly patients. There were an estimated 39.2 million injury-related visits during 2002, or 13.8 visits per 100 persons. Diagnostic/screening services, procedures, and medications were provided at 86.8 percent, 43.2 percent, and 75.8 percent of visits, respectively. In 2002, approximately 12 percent of ED visits resulted in hospital admission. On average, patients spent 3.2 hours in the ED.
