Introduction: This report uses data from the 2022‒2023 National Survey of Family Growth (NSFG) to estimate receipt of family planning services by selected characteristics among females ages 15‒49 in the United States.

Methods: NSFG data were collected through a multi-mode design (in-person and web interviews) with a nationally representative samples of males and females ages 15-49 in the household population of the United States. This report uses data from 5,586 females who completed the survey between January 2022 and December 2023.

Key findings: During 2022‒2023, 35.7% of females ages 15‒49 received a family planning service in the past 12 months. A larger percentage of White, non-Hispanic females ages 15‒49 received a family planning service (39.7%) compared with Black, non-Hispanic (34.7%) and Hispanic (32.4%) females.

Introduction: This report presents final 2023 U.S. mortality data on deaths and death rates by variables such as sex, age, race and Hispanic origin, and cause of death.

Key findings: Life expectancy for the U.S. population in 2023 was 78.4 years, an increase of 0.9 year from 2022. The age-adjusted death rate decreased by 6.0% from 798.8 deaths per 100,000 standard population in 2022 to 750.5 in 2023. Age-specific death rates decreased from 2022 to 2023 for all age groups 5 years and older.

Methods: The data shown in this report reflect information collected by the National Center for Health Statistics for 2022 and 2023 from death certificates filed in all 50 states and the District of Columbia and compiled into national data known as the National Vital Statistics System. The race and Hispanic-origin groups shown in this report follow the 1997 Office of Management and Budget standards and differ from the bridged-race categories shown in reports for data years before 2018.

Objectives: This report presents provisional 2023 data on infant mortality rates using the U.S. linked birth/infant death files. Infant mortality rates are shown by infant age at death, maternal race and Hispanic origin, maternal age, gestational age, sex of the newborn, maternal state of residence, and the 10 leading causes of infant death.

Methods: Data are from the period linked birth/infant death files, which link infant deaths with the corresponding birth certificates. Comparisons are made between provisional 2023 and final 2022 data. The linked birth/infant files are based on 100% of birth certificates and 98%-99% of infant death certificates registered in all states and the District of Columbia. For 2023, 1.2% of infant deaths remained unlinked. Infant deaths in states with less than 100% of infant death records linked to their respective birth records are weighted.

Results: In 2023, the U.S. provisional infant mortality rate was 5.61 infant deaths per 1,000 live births, unchanged from the rate in 2022. From 2022 to 2023, changes in the neonatal mortality rate (from 3.59 to 3.65) and the postneonatal mortality rate (from 2.02 to 1.96) were not statistically significant. Changes in infant mortality rates were not significant by most of the characteristics examined: maternal race and Hispanic origin, maternal age, gestational age, sex, or the 10 leading causes of infant death. By state, infant mortality rates increased in Nevada and Washington and declined in New Mexico and West Virginia.

Introduction: This report presents prevalence of high total cholesterol and low high-density lipoprotein cholesterol (HDL-C) by sex and age group for adults age 20 and older from the August 2021-August 2023 National Health and Nutrition Examination Survey (NHANES). Trends in the prevalence of high total cholesterol and low HDL-C are also presented.

Methods: Data from the August 2021-August 2023 NHANES were used to estimate the prevalence of high total cholesterol (240 mg/dL or higher) and low HDL-C (less than 40 mg/dL). NHANES's complex, multistage probability sample is representative of the U.S. civilian noninstitutionalized population. The prevalence of high total cholesterol and low HDL-C were calculated using survey weights. Standard errors were estimated using Taylor series linearization, a method that accounts for the complex sample design. Differences between groups were tested using a t statistic at the p < 0.05 significance level. Linear trends for subgroups were tested using orthogonal contrast matrices, and linear and nonlinear trends over time were tested using JoinPoint software and linear regression, accounting for unequal duration and spacing of survey cycles.

Key findings: During August 2021-August 2023, the prevalence of high total cholesterol was 11.3% in adults, with no significant difference between men and women overall. The prevalence of high total cholesterol was higher in adults ages 40-59 (16.7%) than in adults ages 20-39 (6.0%) and 60 and older (11.3%). The prevalence was lower in adults ages 20-39 compared with adults 60 and older. The pattern by age was different in men than in women. The prevalence of low HDL-C in adults was 13.8%, was higher in men (21.5%) than in women (6.6%) overall, and declined with increasing age for both men and women. High total cholesterol prevalence declined from 1999-2000 to 2013-2014 and remained stable through August 2021-August 2023. Low HDL-C prevalence declined from 2007-2008 to August 2021-August 2023.

Objectives: This report explores changes in the overall rate of triplet and higher-order births from 1998 to 2023 by detailed plurality, maternal race and Hispanic origin, and age.

Methods: Data are from the National Vital Statistics System birth files. Triplet and higher-order birth rates (number of triplet and higher-order births per 100,000 births) from 1998 to 2023 are presented. Also presented are the number of triplet, triplet and higher-order, and quadruplet and higher-order births, and triplet and higher-order multiple birth rates by maternal race and Hispanic origin and maternal age for 1998, 2009, and 2023.

Results: From 1998 to 2023, the triplet and higher-order multiple birth rate declined 62%, from 193.5 per 100,000 total births to 73.8; the largest declines were from 2009 to 2023. The number of triplet and higher-order births declined from 7,625 to 2,653. Declines in triplet and higher-order birth rates were observed for White non-Hispanic (71%) and Hispanic (25%) mothers, while the rate for Black non-Hispanic mothers increased (25%). Triplet and higher-order birth rates declined for all age groups 20 and older from 1998 to 2023, and the largest declines were for mothers age 30 and older.

Introduction: This report describes the self-reported prevalence of daily screen time among teenagers ages 12-17 years and explores whether differences exist by selected characteristics and demographics.

Methods: Data from the July 2021-December 2023 National Health Interview Survey-Teen were used for this analysis. Point estimates and the corresponding confidence intervals were calculated using SAS-callable SUDAAN software to account for the complex sample design of NHIS-Teen. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level.

Key findings: During July 2021-December 2023, about one-half of teenagers had 4 hours or more of daily screen time (50.4%). Black non-Hispanic teenagers (60.4%) were most likely to have 4 hours or more of daily screen time compared with teenagers in other race and Hispanic origin groups. About 1 in 4 teenagers with 4 hours or more of daily screen time have experienced anxiety (27.1%) or depression symptoms (25.9%) in the past 2 weeks.

Introduction: This report describes the percentage of teenagers ages 12â17 who self-reported that they were bullied in the past 12 months, by selected characteristics.

Methods: Data between July 2021 and December 2023 from the National Health Interview SurveyâTeen were used for this analysis. Point estimates and the corresponding confidence intervals were calculated using SAS-callable SUDAAN software to account for the complex sample design of NHISâTeen. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level.

Key findings: During July 2021 to December 2023, 34.0% of teenagers were bullied in the last 12 months. Sexual and gender minority teenagers were more likely to be bullied (47.1%) than teenagers who are not a sexual or gender minority (30.0%). White non-Hispanic teenagers were more likely to be bullied compared with teenagers in other race and Hispanic-origin groups. Teenagers with a developmental disability were more likely to be bullied than teenagers without a developmental disability. Teenagers who were bullied were nearly twice as likely to experience symptoms of anxiety (29.8%) or depression (28.5%) in the last 2 weeks when compared with teenagers who were not bullied.

Introduction: This report uses data from the 2023 National Health Interview Survey to provide updated percentages of adults who experienced chronic pain and high-impact chronic pain in the past 3 months by selected demographic characteristics and urbanization level.

Methods: Point estimates and corresponding confidence intervals for this analysis were calculated using SAS-callable SUDAAN software to account for the complex sample design of the National Health Interview Survey. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level. Linear and quadratic trends by age group and urbanization level were evaluated using orthogonal polynomials.

Key findings: In 2023, 24.3% of adults had chronic pain, and 8.5% of adults had high impact chronic pain in the past 3 months. American Indian and Alaska Native non-Hispanic adults were significantly more likely to have chronic pain (30.7%) compared with Asian non-Hispanic (11.8%) and Hispanic (17.1%) adults. The percentage of adults with chronic pain and high-impact chronic pain increased with decreasing urbanization level.

Objectives: This report describes changes in total, early, and late fetal mortality between 2022 and 2023 (provisional), as well as fetal mortality by maternal race and Hispanic origin and state of residence. Comparisons are made with findings from 2021 to 2022.

Methods: Data are based on reports of fetal death filed in the 50 states and the District of Columbia and collected via the National Vital Statistics System. In this report, only fetal deaths reported at 20 weeks of gestation or more are included. Data for 2021 and 2022 are final and data for 2023 are provisional.

Results: In 2023, the overall fetal mortality rate was 5.52 fetal deaths per 1,000 live births and fetal deaths, which was not significantly different from the 2022 rate (5.48). From 2022 to 2023, the early fetal mortality rate (20-27 weeks of gestation) significantly increased by 4% to 2.89 per 1,000, while the late fetal mortality rate (28 weeks of gestation or more) was essentially unchanged at 2.64. Among the race and Hispanic-origin groups, the fetal mortality rate increased for Asian non-Hispanic women and was not significantly different for other groups. Fetal mortality rates increased in 4 states, declined in 1 state, and were not significantly different for 45 states and the District of Columbia from 2022 to 2023. In comparison, from 2021 to 2022, the fetal mortality rate declined for total, early, and late fetal deaths, as well as for White non-Hispanic women and in five states.

Introduction: This report provides final 2022 suicide numbers and age-adjusted rates, updating a provisional 2022 suicide report.

Methods: Data were analyzed using National Vital Statistics System multiple cause-of-death mortality files for 2002 through 2022, with suicide deaths identified using International Classification of Diseases, 10th Revision underlying cause-of-death codes U03, X60-X84, and Y87.0. Age-adjusted death rates were calculated using the direct method and the 2000 U.S. standard population. Pairwise comparisons were conducted using the z test with an alpha level of 0.05, and trends were assessed using the Joinpoint Regression Program (5.0.2).

Key findings: After increasing from 2002 to 2018, the age-adjusted suicide rate declined from 2018 (14.2 deaths per 100,000 standard population) through 2020 (13.5) but then increased 5%, to 14.2 in 2022. Following a period of decline between 2018 and 2020, suicide rates generally increased between 2020 and 2022 for females ages 25 and older. For males ages 10-14 and 15-24, rates decreased between 2020 and 2022, while rates for older age groups generally increased. For females in 2022, firearm-related suicide (2.0) was the leading means of suicide, with rates generally increasing since 2007. For males in 2022, firearm-related suicide (13.5) was the leading means of suicide, with rates increasing since 2006.
