Introduction: This report provides prevalence estimates of adult obesity and severe obesity during August 2021-August 2023 by age and sex, as well as obesity prevalence by education level. Trends in the prevalence of adult obesity and severe obesity over the previous 10 years are also shown.

Methods: Data from the August 2021-August 2023 National Health and Nutrition Examination Survey (NHANES) were used for prevalence estimates, incorporating examination survey sample weights into the analysis and accounting for the survey's complex, multistage probability design. Measured height and weight were used to calculate body mass index (BMI) to define obesity (BMI at or above 30) and severe obesity (BMI at or above 40). Differences between estimates overall, among subgroups, and compared with 2017-March 2020 were evaluated using t tests at the 0.05 level. Data from four NHANES cycles (2013-2014, 2015-2016, 2017-March 2020, and August 2021-August 2023) were used to assess 10-year trends. Polynomial regression was used to test the significance of linear and nonlinear 10-year trends, accounting for the unequal spacing and lengths of survey cycles.

Key findings: During August 2021-August 2023, the prevalence of obesity in adults was 40.3%, with no significant differences between men and women. Obesity prevalence was higher in adults ages 40-59 than in ages 20-39 and 60 and older. The prevalence of obesity was lower in adults with a bachelor's degree or more than in adults with less education. The prevalence of severe obesity in adults was 9.4% and was higher in women than men for each age group. From 2013-2014 through August 2021-August 2023, the age-adjusted prevalence of obesity did not change significantly, while severe obesity prevalence increased from 7.7% to 9.7%.

Objectives: This report presents 2023 data on U.S. births compared with 2022 and 2021 for several key demographic and maternal and infant characteristics.

Methods: Descriptive tabulations of data reported on the birth certificates of the 3.60 million births that occurred in 2023 are presented. Data are presented for the number of births, the general fertility rate, teenage birth rates, the distribution of births by trimester prenatal care began and the distribution of births by selected gestational age categories. Data for 2023 are compared with data for 2022 and 2021.

Results: A total of 3,596,017 births were registered in the United States in 2023, down 2% from 2022. The general fertility rate declined 3% in 2023 to 54.5 births per 1,000 females ages 15-44. Birth rates declined for females ages 15-19 (4%), 15-17 (2%), and 18-19 (5%), from 2022 to 2023. The percentage of mothers receiving prenatal care in the first trimester of pregnancy declined 1% to 76.1% in 2023 while the percentage of mothers with no prenatal care increased 5%. The preterm birth rate was essentially unchanged at 10.41% in 2023 but the rate of early term births rose 2%.

Introduction: This report presents characteristics of emergency department (ED) visits by age group, sex, race and ethnicity, payment source, and mention of COVID-19, using data from the 2022 National Hospital Ambulatory Medical Care Survey (NHAMCS).

Methods: Data for this report are from NHAMCS, an annual, nationally representative survey of nonfederal, general, and short-stay hospitals. Data analyses were performed using the statistical packages SAS version 9.4 and SAS-callable SUDAAN. Two-tailed t tests with a significance level of p < 0.05 were used to determine statistically significant differences between ED visit rates.

Key findings: The overall ED visit rate was 47 visits per 100 people in 2022, and the ED visit rates were highest for infants younger than age 1 year (99 visits per 100 infants) and adults ages 75 and older (76 per 100 adults). The ED visit rate for Black or African American non-Hispanic people (91) was the highest among the selected racial and ethnic groups. In 2022, a COVID-19 diagnosis was confirmed for 4.8% of all ED patient visits.

Introduction: This Data Brief presents trends in stroke death rates among people ages 45-64, in total and by sex, for 2002 to 2022. Trends are also presented for men and women by region (Northeast, Midwest, South, and West) from 2002 to 2022. For 2022, stroke death rates are presented for men and women by race and Hispanic origin within each region.

Methods: Mortality data for 2002-2017 are from the National Center for Health Statistics' 1999-2020 Underlying Cause of Death by Bridged-Race Categories and data for 2018-2022 are from the 2018-2022 Underlying Cause of Death by Single-Race Categories. Stroke deaths are for people ages 45-64 and are identified by International Classification of Diseases, 10th Revision underlying cause-of-death codes I60-I69. The four regions of the United States are: Northeast, Midwest, South, and West. The four race and Hispanic-origin groups in this report are: Asian non-Hispanic; Black non-Hispanic; White non-Hispanic, and Hispanic. These groups had at least 20 stroke deaths among men and women in all regions to compute reliable rates. Line trends were evaluated using the National Cancer Institute's Joinpoint Regression Program. Pairwise comparisons were tested using the z test statistic at p < 0.05.

Key findings: After declines between 2002 and 2012, stroke death rates for adults ages 45-64 increased 7% between 2012 (20.2 per 100,000) and 2019 (21.7) and an additional 12% through 2021 (24.4). Throughout the period, the highest stroke death rates for both men and women were in the South and the lowest were in the Northeast. In each region, differences in stroke death rates by race and Hispanic origin were seen, as Black men and women had rates that were at least twice those of all other groups.

Introduction: This report contains the most recent national estimates of selected characteristics of adult day services center participants.

Methods: Data are from the adult day services center component of the 2022 wave of the biennial National Post-acute and Long-term Care Study. Data analyses excluded missing data, incorporated complex survey weights, and were performed using Stata/SE version 17.0.

Key findings: In 2022, 58% of adult day services center participants were female, 40% were White non-Hispanic, and 32% were younger than age 65. Most participants were Medicaid users. About 61% of participants needed assistance with three to six activities of daily living and had two or more chronic conditions.

Introduction: This report describes the percentage of adults age 18 and older who practiced yoga, and among those, the percentage who practiced yoga to restore overall health, practice meditation, or treat and manage pain, by selected sociodemographic characteristics using data from the 2022 National Health Interview Survey.

Methods: Data from the 2022 National Health Interview Survey were used for this analysis. Point estimates and corresponding variances were calculated using SAS-callable SUDAAN software version 11.0 to account for the survey’s complex sample design. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level. Linear and quadratic trends by age group and family income were evaluated using orthogonal polynomials in logistic regression. Estimates were age adjusted to the 2000 U.S. census population using the direct method for age groups 18–44, 45–64, and 65 and older.

Key findings: In 2022, the age-adjusted percentage of adults age 18 and older who practiced yoga in the past 12 months was 16.9%, and percentages were highest among women, adults ages 18–44, Asian non-Hispanic (subsequently, Asian) adults, and those with family incomes at 400% of the federal poverty level or more. The percentage of adults who practiced meditation as part of yoga was lower among men (52.9%), adults age 45 and older, Asian (56.7%) and White non-Hispanic (54.0%) adults, and those with family incomes at 200% of the federal poverty level or more. The percentage of adults who practiced yoga to treat or manage pain decreased with increasing family income.

Oral health is associated with overall health, especially in older adults (age 65 and older). Chronic conditions in older adults may affect oral health, and poor oral health may increase the risk of certain chronic conditions (1-3). Poor oral health has also been associated with increased cardiovascular disease risk (4). Several factors, including chronic conditions, health status, race, and income have been associated with reduced dental care use among older adults (5-9). This report describes the percentage of older adults who had a dental visit in the past 12 months by selected sociodemographic characteristics and chronic conditions using the 2022 National Health Interview Survey (NHIS). .

Chronic school absenteeism can lead to poorer academic performance and school engagement for students (1). It is also a risk factor for school dropout (2,3), which is associated with many long-term health impacts (4,5). This report uses data from the 2022 National Health Interview Survey (NHIS) to describe the percentage of children ages 5‒17 who experienced chronic school absenteeism due to illness, injury, or disability by sociodemographic and health factors.

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders of childhood (1). It is characterized by a pattern of inattention, impulsivity, or hyperactivity that leads to functional impairment experienced in multiple settings (2). Symptoms of ADHD occur during childhood, and many children continue to have symptoms and impairment through adolescence and into adulthood (3). This report describes the percentage of children and adolescents ages 5-17 years who had ever been diagnosed with ADHD from the 2020-2022 National Health Interview Survey (NHIS).
