Births: Final Data for 2019.

Objectives-This report presents 2019 data on U.S. births according to a wide variety of characteristics. Trends in fertility patterns and maternal and infant characteristics are described and interpreted. Methods-Descriptive tabulations of data reported on the birth certificates of the 3.75 million births that occurred in 2019 are presented. Data are presented for maternal age, livebirth order, race and Hispanic origin, marital status, tobacco use, prenatal care, source of payment for the delivery, method of delivery, gestational age, birthweight, and plurality. Selected data by mother's state of residence and birth rates by age are also shown. Trend data for 2010 through 2019 are presented for selected items. Trend data by race and Hispanic origin are shown for 2016-2019. Results-A total of 3,747,540 births were registered in the United States in 2019, down 1% from 2018. The general fertility rate declined from 2018 to 58.3 births per 1,000 women aged 15-44 in 2019. The birth rate for females aged 15-19 fell 4% between 2018 and 2019. Birth rates declined for women aged 20-34 and increased for women aged 35-44 for 2018-2019. The total fertility rate declined to 1,706.0 births per 1,000 women in 2019. Birth rates declined for both married and unmarried women from 2018 to 2019. The percentage of women who began prenatal care in the first trimester of pregnancy rose to 77.6% in 2019; the percentage of all women who smoked during pregnancy declined to 6.0%. The cesarean delivery rate decreased to 31.7% in 2019 (Figure 1). Medicaid was the source of payment for 42.1% of all births in 2019. The preterm birth rate rose for the fifth straight year to 10.23% in 2019; the rate of low birthweight was essentially unchanged from 2018 at 8.31%. Twin and triplet and higher-order multiple birth rates both declined in 2019 compared with 2018.

Early adolescent childbearing in Colombia: time-trends and consequences / Maternidad prematura adolescente en Colombia: tendencias temporales y consecuencias / Gravidez precoce na adolescência na Colômbia: tendências temporais e consequências

Teenage childbearing has been increasing, especially among girls aged 10 to 14 years, slowing the improvements in public health and propelling social marginalization. The objective of this article is to study adolescent pregnancy in Colombia and suggest possible policy interventions. The study comprises univariate and multivariate analyses that examine trends and correlates of teenage childbirth and related infant mortality in Colombia between 2001-2011 using complete vital statistics. The study compares, by relative risk analysis as well, two groups of teenage mothers, aged 10 to 14 years and 15 to 19 years, with a reference group of mothers aged 20 to 34 years. During the study period, the average of annual birth rates increased 2.6% and 0.8% in mothers aged 10 to 14 years, and 15 to 19 years respectively, whereas it declined at an average rate of 0.2% annually for mothers aged 20 to 35 years. Simultaneously, while the overall rate declined, the infant mortality rate (IMR) of the youngest group was consistently higher during the entire period compared to the IMR of older groups. Compared with the other groups, mothers aged from 10 to 14 were more likely to be unmarried, rural, indigenous or afro-descendant, and have less access to health care. The study demonstrates that early teenage childbirth is a growing challenge at least in Colombia. These mothers are at higher risk of losing their babies while being poor and remaining poor. The study suggests the need for policy that targets appropriate education and health care to poor girls as early as age 10 and even younger.

La maternidad prematura se ha visto incrementada, especialmente entre niñas con edades comprendidas entre los 10 a 14 años, aminorando mejoras en la salud pública y propagando la marginalización social. El objetivo de este artículo es estudiar los embarazos adolescentes en Colombia y sugerir posibles políticas de intervención. El estudio abarca análisis univariados y multivariados que examinan tendencias y correlacionan el parto en la adolescencia y la mortalidad infantil relacionada, en Colombia, durante el periodo de 2001 a 2011, usando estadísticas vitales completas. El estudio compara, también, mediante un análisis de riesgos relativos, a dos grupos de madres adolescentes, con edades de 10 a 14 y edades de 15 a 19 años, con un grupo de referencia, madres con edades de 20 a 34. Durante el período de estudio, la media anual de la tasa de natalidad se incrementó un 2,6% y un 0,8% en madres con edades de 10 a 14 años, y edades de 15 a 19 años, respectivamente, mientras que decreció a una tasa media de 0,2% anualmente en madres con 20-35 años de edad. Simultáneamente, mientras disminuía en general, la tasa de mortalidad infantil (TMI) del grupo más joven fue consistentemente más alta durante todo el período que la TMI de los grupos con mayor edad. Comparadas con otros grupos, las madres con edades entre 10 a 14 años eran más propensas a no estar casadas, ser procedentes del ámbito rural, indígenas o afro-mulatas, y contar con menor acceso a servicios de salud. El estudio demuestra que la maternidad prematura en adolescentes es un desafío creciente, al menos en Colombia. Estas madres tienen un riesgo más alto de perder a sus bebés mientras están en situación de pobreza. El estudio indica la necesidad de políticas que tengan como objetivo una educación apropiada y cuidados de salud, dirigidos a niñas pobres, desde una edad tan temprana como los 10 años o incluso más jóvenes.

A gravidez na adolescência tem crescido, especialmente na faixa etária de 10 a 14 anos, freando avanços na saúde pública e impulsionando a marginalização social. O objetivo deste artigo é estudar a gravidez na adolescência na Colômbia e sugerir possíveis intervenções de políticas públicas. O estudo consiste em análises univariadas e multivariadas que examinam tendências e correlativos da gravidez na adolescência e da mortalidade infantil associada na Colômbia no período de 2001 a 2011 usando estatísticas vitais completas. O estudo compara, também por meio de análise de risco relativo, dois grupos de mães adolescentes, com idade entre 10 e 14 anos e entre 15 e 19 anos, com um grupo de referência, mães com idade entre 20 e 34 anos. Durante o período do estudo, as taxas médias anuais de natalidade aumentaram em 2,6% e 0,8% entre as mães com idade entre 10 e 14 e entre 15 e 19 anos, respectivamente, ao mesmo tempo em que sofreram uma redução, a uma taxa média anual de 0,2%, entre as mães com idade entre 20 e 35 anos. Ao mesmo tempo, a taxa de mortalidade infantil (TMI) do grupo mais jovem foi consistentemente mais alta do que a dos grupos mais velhos, ainda que tenha sofrido uma redução. Quando comparadas aos outros grupos, mães com idade entre 10 e 14 anos tinham maior probabilidade de serem solteiras, indígenas ou Afro-mulatas, viverem em áreas rurais e terem menos acesso a serviços de saúde. Este estudo demonstra que a gravidez precoce na adolescência é um desafio crescente, pelo menos na Colômbia. Essas mães têm risco maior de perderem seus bebês e, simultaneamente, de serem e permanecerem pobres. O estudo sugere a necessidade de políticas dirigidas à educação e serviços de saúde apropriados para meninas pobres a partir dos 10 anos e até mais jovens.

Births: Final Data for 2016.

This report presents 2016 data on U.S. births according to a wide variety of characteristics. Trends in fertility patterns and maternal and infant characteristics are described and interpreted.Descriptive tabulations of data reported on the birth certificates of the 3.95 million births that occurred in 2016 are presented. Data are presented for maternal age, live-birth order, race and Hispanic origin, marital status, tobacco use, prenatal care, source of payment for the delivery, method of delivery, gestational age, birthweight, and plurality. Selected data by mother's state of residence and birth rates by age also are shown. Trend data for 2010-2016 are presented for selected items. A total of 3,945,875 births were registered in the United States in 2016, down 1% from 2015. Compared with rates in 2015, the general fertility rate declined to 62.0 per 1,000 women aged 15-44. The birth rate for females aged 15-19 fell 9% in 2016. Birth rates declined for women in their 20s but increased for women intheir 30s and early 40s. The total fertility rate declined to 1,820.5 births per 1,000 women in 2016. The birth rate for unmarried women declined, while the rate for married women increased. More than three-quarters of women began prenatal care in the firsttrimester of pregnancy (77.1%) in 2016, while 7.2% of all women smoked during pregnancy. The cesarean delivery rate declined for the fourth year in a row. Medicaid was the source of payment for 42.6% of all 2016 births. The preterm birth rate rose for the second straight year, and the rate of low birthweight increased 1%. Twin and triplet and higher-order multiple birth rates declined, although the changes were not statistically significant.

Selected data by mother's state of residence and birth rates by age also are shown. Trend data for 2010 to 2017 are presented for selected items. Trend data by race and Hispanic origin are shown for 2016 and 2017. Results- A total of 3,855,500 births were registered in the United States in 2017, down 2% from 2016. Compared with rates in 2016, the general fertility rate declined to 60.3 births per 1,000 women aged 15-44. The birth rate for females aged 15-19 fell 7% in 2017. Birth rates declined for women in their 20s and 30s but increased for women in their early 40s. The total fertility rate declined to 1,765.5 births per 1,000 women in 2017. Birth rates for both married and unmarried women declined from 2016 to 2017. The percentage of women who began prenatal care in the first trimester of pregnancy rose to 77.3% in 2017; the percentage of all women who smoked during pregnancy declined to 6.9%. The cesarean delivery rate increased to 32.0% following 4 years of declines. Medicaid was the source of payment for 43.0% of all births in 2017, up 1% from 2016. The preterm birth rate rose for the third straight year, as did the rate of low birthweight. Twin and triplet and higher-order multiple birth rates were essentially stable in 2017.

Gender inequality and the 'East-West' divide in contraception: An analysis at the individual, the couple, and the country level.

Despite generally low fertility rates in Europe, contraceptive behavior varies to a substantial extent. The dichotomy between Western, and Central and Eastern European countries is particularly relevant. Whereas the former are characterized by the widespread use of modern contraception, the latter show a high prevalence of traditional methods to control fertility. The current study aims to examine whether these differences can be attributed to differences in women's individual status, and in gender inequality at the couple and the country level. We combine data from the Generations and Gender Survey (2004-2011) and the Demographic Health Survey (2005-2009), covering seventeen European countries, to perform multinomial multilevel analyses. The results confirm that higher educated and employed women, and women who have an equal occupational status relative to their partner are more likely to use modern reversible contraception instead of no, traditional, or permanent methods. Absolute and relative employment are also positively related to using female instead of male methods. Furthermore, it is shown that higher levels of country-level gender equality are associated with a higher likelihood of using modern reversible and female methods, but not sterilization. Particularly country levels of gender equality are linked to the East-West divide in type of contraceptive method used. Our findings underscore that women's higher status is closely related to their use of effective, female contraception.

Prenatal care through the eyes of Canadian Aboriginal women.

The Aboriginal Prenatal Wellness Program (APWP) in Canada represents a culturally safe approach to prenatal care. By understanding the history of colonization and residential schools and how this history has contributed to health disparities, a multidisciplinary team provides culturally competent and integrated prenatal care to Aboriginal women and their families. This article describes the APWP and discusses how increased participation in health care by historically marginalized populations can lead to better maternal and neonatal health outcomes.

Recent pregnancy trends among early adolescent girls in Japan.

AIM: The paper examines recent time trends, explores potentially influential background factors and discusses prevention strategies of pregnancy among girls under 15 years of age in Japan. METHODS: Using Japanese government data, we first analyzed time trends of early adolescence (<15 years of age) abortion, live birth and child sexual abuse from 2003 to 2010. Second, we analyzed ecological correlations of early adolescent pregnancy (abortion, live birth and stillbirth) with pregnancy in other age groups, child sexual abuse, and indicators of juvenile victimization and juvenile delinquency, using prefectural data. RESULTS: We found that rates of both abortion and live birth in early adolescents have increased since 2005 (annual percent change 5.3% and 2.3%, respectively), despite declining rates in older age groups. The abortion ratio in early adolescence remained the highest among all age groups in Japan. The early adolescent pregnancy rate showed significant correlation with the rates of juvenile victimization of welfare crimes (obscenity, alcohol drinking, smoking and drug use) (Spearman's rank correlation coefficient [rs] = 0.42, P = 0.00) and juvenile delinquency among junior high school students (12-14 years of age) (rs = 0.69, P = 0.00). CONCLUSION: The observed rise in rates of abortion, live birth and child sexual abuse among early adolescents along with strong ecological correlations of their pregnancy rate with juvenile victimization and delinquency indicators suggests that epidemiological investigation and public health programs at the individual and community levels are needed to address the complex social roots of these trends and to produce effective improvements in early adolescent reproductive health.

Prostate cancer mortality and birth or adult residence in the southern United States.

PURPOSE: Although there are few confirmed risk factors for prostate cancer (PCa), mortality rates are known to vary geographically across the United States. PCa mortality is higher among black and younger white men in a band of states spanning from Washington DC to Louisiana (the "PCa belt"). This study assessed the associations of birth and adult residence in the PCa belt with PCa mortality among black and white men and trends in these associations over time. METHODS: PCa-specific mortality rates in 1980, 1990, and 2000 for black and white men born in the continental US, aged 40-89, were calculated by linking national mortality records with population data based on birth state, state of residence at the census, race, and age. PCa belt (Washington DC, Virginia, North Carolina, South Carolina, Georgia, Mississippi, Alabama, and Louisiana) birth was cross-classified against PCa belt adult residence. RESULTS: Black men born in the PCa belt had elevated PCa mortality in 1980, 1990, and 2000. Associations were independent of adult residence in the PCa belt. For example, in 2000, black men aged 65-89 who were born in the PCa belt but no longer lived there in adulthood had an odds ratio of 1.19 (1.14-1.24) for PCa mortality compared to black men born and residing outside the PCa belt. The PCa belt was not associated with PCa mortality among whites. CONCLUSIONS: Geographically patterned childhood exposures, for example, differences in social or environmental conditions, or behavioral norms, may influence PCa mortality.

Early respiratory morbidity in a multicultural birth cohort: the Generation R Study.

Ethnic disparities in the prevalence of asthma symptoms in children have been described. We evaluated to what extent the association between ethnic background and respiratory symptoms during the first 2 years of life could be explained by the mediating effect of risk factors for respiratory morbidity. The Generation R Study is a multiethnic, population-based birth cohort study. Pre and postnatal risk factors for respiratory morbidity were prospectively assessed by questionnaires. Information about ethnicity was available for 5,684 infants. The associations between ethnic background and lower respiratory symptoms at 12 and 24 months were evaluated with log-binomial regression models. Relative risks and 95 % confidence intervals (RR [95 % CI]) were computed for Cape Verdean, Moroccan, Antillean, Surinamese and Turkish ethnicity with Dutch ethnicity as the reference category. We found an increased risk of lower respiratory symptoms at 24 months in Antillean infants (1.32 [95 % CI 1.12-1.57]) that was mediated by early postnatal exposures (pets keeping, siblings, breastfeeding, daycare attendance, smoke exposure). Turkish infants also had an increased risk of lower respiratory symptoms at 12 and 24 months (1.14 [95 % CI 1.02-1.27] and 1.21 [95 % CI 1.07-1.38], respectively), partly explained by previous morbidity (eczema, infections and upper respiratory symptoms). There were no differences for Cape Verdean, Moroccan or Surinamese, as compared to Dutch infants. Hence, ethnic background was associated with respiratory symptoms during the first 2 years of life and this association was largely explained by mediating effects of known pre and postnatal risk factors for respiratory morbidity.

The quest for equity in Latin America: a comparative analysis of the health care reforms in Brazil and Colombia.

INTRODUCTION: Brazil and Colombia have pursued extensive reforms of their health care systems in the last couple of decades. The purported goals of such reforms were to improve access, increase efficiency and reduce health inequities. Notwithstanding their common goals, each country sought a very different pathway to achieve them. While Brazil attempted to reestablish a greater level of State control through a public national health system, Colombia embraced market competition under an employer-based social insurance scheme. This work thus aims to shed some light onto why they pursued divergent strategies and what that has meant in terms of health outcomes. METHODS: A critical review of the literature concerning equity frameworks, as well as the health care reforms in Brazil and Colombia was conducted. Then, the shortfall inequality values of crude mortality rate, infant mortality rate, under-five mortality rate, and life expectancy for the period 1960-2005 were calculated for both countries. Subsequently, bivariate and multivariate linear regression analyses were performed and controlled for possibly confounding factors. RESULTS: When controlling for the underlying historical time trend, both countries appear to have experienced a deceleration of the pace of improvements in the years following the reforms, for all the variables analyzed. In the case of Colombia, some of the previous gains in under-five mortality rate and crude mortality rate were, in fact, reversed. CONCLUSIONS: Neither reform seems to have had a decisive positive impact on the health outcomes analyzed for the defined time period of this research. This, in turn, may be a consequence of both internal characteristics of the respective reforms and external factors beyond the direct control of health reformers. Among the internal characteristics: underfunding, unbridled decentralization and inequitable access to care seem to have been the main constraints. Conversely, international economic adversities, high levels of rural and urban violence, along with entrenched income inequalities seem to have accounted for the highest burden among external factors.

Aspectos demográficos e mortalidade de populações indígenas do Estado do Mato Grosso do Sul, Brasil / Demographic characteristics and mortality among indigenous peoples in Mato Grosso do Sul State, Brazil

O objetivo do estudo foi o de analisar os aspectos demográficos e o padrão de mortalidade da população indígena aldeada do Estado do Mato Grosso do Sul, Brasil, comparativamente ao da população total do estado. Foram calculados indicadores de mortalidade a partir dos dados obtidos do Sistema de Informação de Atenção à Saúde Indígena e do consolidado mensal, assim como, do módulo demográfico e do Sistema de Informações sobre Mortalidade do SUS. Observaram-se, na população indígena, comparativamente à do estado, maior proporção de indivíduos menores de 15 anos e menor de idosos e taxas mais elevadas de mortalidade em idades precoces e por doenças infecciosas e parasitárias. Os homens indígenas apresentaram taxas significativamente maiores para as causas externas, doenças do aparelho respiratório e doenças infecciosas. Entre as mulheres, apenas as causas externas e doenças infecciosas se destacaram. A grande importância dos suicídios na juventude apresentou-se como aspecto relevante. As condições de saúde da população indígena são piores que a da população total.

The present study aimed to assess mortality rates and related demographic factors among indigenous peoples in the State of Mato Grosso do Sul, Central-West Brazil, compared to the State's general population. Mortality rates were estimated based on data obtained from the Health Care Database for Indigenous Peoples and monthly patient care records as well as demographic data from the Brazilian Unified National Health System (SUS) and mortality data from the SUS Mortality Database. Compared to the overall population, among indigenous peoples there were proportionally more individuals under 15 years of age and fewer elderly, besides higher mortality rates at early ages and from infectious and parasitic diseases. Indigenous men showed significantly higher mortality rates from external causes and respiratory and infectious diseases, while among women the mortality rates from external causes and infectious diseases were higher. Suicide rates among young indigenous individuals were also particularly alarming. Indigenous people's health conditions are worse than those of the general population in Mato Grosso do Sul.

Demography and health of the Xavante Indians of Central Brazil / Demografia e saúde do povo indígena Xavante de Mato Grosso, Brasil

This study investigates the demographic and health behavior of the Xavante Indians of Mato Grosso State, Central Brazil. Data covering the period 1999 to 2004 was collected using information from household censuses and vital statistics. In addition to standard demographic analyses, survival analysis was carried out. Results show a young age structure, derived from a combination of high fertility rates (7.7 live births per woman) and declining mortality. Mortality rates, especially infant mortality (97 per thousand), remain very high, surpassing regional and national rates. Natural increase is the main contributing factor to population growth. The annual population growth rate is 4.4 percent. Results suggest that recent declines in mortality and fertility may be related to transformations in the implementation of basic health care services and internal diversity, the latter of which seems to be associated with local history and sociocultural determinants.

Este estudo investiga o comportamento demográfico dos índios Xavante de Mato Grosso, Brasil Central. Os dados foram coletados entre 1999 e 2004, a partir de censos domiciliares e da coleta de estatísticas vitais. Além das análises demográficas, realizou-se análise de sobrevida. Os Xavante apresentam uma estrutura etária jovem, típica de população em fase de recuperação populacional, com alta fecundidade (média de 7,7 nascidos vivos por mulher) e mortalidade em declínio. As taxas de mortalidade, especialmente a infantil (97 por mil), continuam a ser muito elevadas, ultrapassando as taxas regionais e nacionais. O crescimento natural é o principal fator no aumento populacional. A população cresce a uma taxa média de 4,4 por cento ao ano. Argumenta-se que não somente a recente queda da mortalidade, assim como da fecundidade, podem estar relacionadas à implementação do novo sistema de saúde voltado para os povos indígenas no Brasil a partir de 1999. Os Xavante apresentam significativa diversidade demográfica interna, que parece estar associada a histórias de contato e a determinantes socioculturais.

Recent decline in births in the United States, 2007-2009.

KEY FINDINGS: From 2007 through 2009, birth rates for women aged 15-44 (fertility rates) fell for most states and nearly all major population subgroups. Birth rates declined for all women under age 40 with some of the largest decreases for women in their peak childbearing years. Fertility rates dropped for all major racial and Hispanic groups with the largest declines among Hispanic women. Birth rates by live-birth order also fell with the largest declines for third-order births and progressively smaller declines for second- and first-order births. Fertility rates decreased or were unchanged in every state and the District of Columbia with the largest declines among western and southeastern states. The number of births in the United States reached an all-time high of 4,316,233 in 2007, but that number has since fallen. From 2007 through 2009, births fell 4 percent to 4,131,019; and the provisional count of births through June 2010 indicated continued declines. Fertility rates--which relate the number of births to women aged 15-44 (i.e., the childbearing years)--also fell during this time frame.This report takes a more detailed look at the decline in births from 2007 through 2009 by mother's age, race and ethnicity, birth order, and state. The analysis is based on a comparison of 2007 final and 2009 preliminary birth data from the National Vital Statistics System (NVSS), and are the most current detailed birth data available.

Births: final data for 2007.

OBJECTIVES: This report presents 2007 data on U.S. births according to a wide variety of characteristics; preliminary 2008 data are also referenced on key measures where available. Final 2007 data are presented for maternal demographic characteristics including age, live-birth order, race and Hispanic origin, marital status, and educational attainment; maternal lifestyle and health characteristics (medical risk factors, weight gain, and tobacco use); medical care utilization by pregnant women (prenatal care, obstetric procedures, characteristics of labor and/or delivery, attendant at birth, and method of delivery); and infant characteristics (period of gestation, birthweight, Apgar score, congenital anomalies, and multiple births). Birth and fertility rates by age, live-birth order, race and Hispanic origin, and marital status also are presented. Selected data by mother's state of residence are shown, as well as data on month and day of birth, sex ratio, and age of father. Trends in fertility patterns and maternal and infant characteristics are described and interpreted. METHODS: Descriptive tabulations are presented of data reported on the birth certificates of the 4.3 million births that occurred in 2007. Preliminary 2008 data are based on 99.9 percent of births occurring in 2008. Denominators for population-based rates are postcensal estimates derived from the U.S. 2000 census. RESULTS: A total of 4,316,233 births were registered in the United States in 2007, the largest number of births ever reported. The general fertility rate increased 1 percent to 69.5 per 1,000. Birth rates increased for women in nearly all age groups. The rate for teenagers rose 1 percent for the year and is up 5 percent from 2005. The total fertility rate increased 1 percent to 2,122.0 births per 1,000 women. Preliminary data for 2008, however, suggest a decline in the number and rate of births overall, and for most age groups under age 40 years. All measures of unmarried childbearing reached record levels in 2007. The cesarean delivery rate rose to another all-time high--31.8 percent. Preterm and low birthweight rates declined slightly, and twin and triplet and higher-order multiple birth rates were essentially unchanged. Preliminary findings for 2008 suggest that these trends continued for cesarean delivery, unmarried childbearing, and preterm births.

Births: final data for 2005.

OBJECTIVES: This report presents 2005 data on U.S. births according to a wide variety of characteristics. Data are presented for maternal demographic characteristics including age, live-birth order, race, Hispanic origin, marital status, and educational attainment; maternal lifestyle and health characteristics (medical risk factors, weight gain, and tobacco use); medical care utilization by pregnant women (prenatal care, obstetric procedures, characteristics of labor and/or delivery, attendant at birth, and method of delivery); and infant characteristics (period of gestation, birthweight, Apgar score, congenital anomalies, and multiple births). Also presented are birth and fertility rates by age, live-birth order, race, Hispanic origin, and marital status. Selected data by mother's state of residence are shown, as well as data on month and day of birth, sex ratio, and age of father. Trends in fertility patterns and maternal and infant characteristics are described and interpreted. METHODS: Descriptive tabulations of data reported on the birth certificates of the 4.1 million births that occurred in 2005 are presented. Denominators for population-based rates are postcensal estimates derived from the U.S. 2000 census. RESULTS: In 2005, 4,138,349 births were registered in the United States, 1 percent more than in 2004. The 2005 crude birth rate was 14.0, unchanged from the previous year; the general fertility rate increased slightly to 66.7. Teenage childbearing continued to decline, dropping to the lowest levels recorded. Rates for women aged 20-29 were fairly stable, whereas childbearing among women 30 years of age and older increased. All measures of unmarried childbearing rose substantially in 2005. Smoking during pregnancy continued to decline. No improvement was seen in the timely initiation of prenatal care. The cesarean delivery rate climbed to more than 30 percent of all births, another all-time high. Preterm and low birthweight rates also continued to rise; the twin birth rate was unchanged and the rate of triplet and higher order multiple births declined for the 7th consecutive year.

Births: final data for 2004.

OBJECTIVES: This report presents 2004 data on U.S. births according to a wide variety of characteristics. Data are presented for maternal demographic characteristics including age, live-birth order, race, Hispanic origin, marital status, and educational attainment; maternal lifestyle and health characteristics (medical risk factors, weight gain, and tobacco use); medical care utilization by pregnant women (prenatal care, obstetric procedures, characteristics of labor and/or delivery, attendant at birth, and method of delivery); and infant characteristics (period of gestation, birthweight, Apgar score, congenital anomalies, and multiple births). Also presented are birth and fertility rates by age, live-birth order, race, Hispanic origin, and marital status. Selected data by mother's state of residence are shown, as well as data on month and day of birth, sex ratio, and age of father. Trends in fertility patterns and maternal and infant characteristics are described and interpreted. METHODS: Descriptive tabulations of data reported on the birth certificates of the 4.1 million births that occurred in 2004 are presented. Denominators for population-based rates are post-censal estimates derived from the U.S. 2000 census. RESULTS: In 2004, 4,112,052 births were registered in the United States, less than 1 percent more than the number in 2003. The crude birth rate declined slightly; the general fertility rate increased by less than 1 percent. Childbearing among teenagers and women aged 20-24 years declined to record lows. Rates for women aged 25-34 and 45-49 years were unchanged, whereas rates for women aged 35-44 years increased. All measures of unmarried childbearing rose in 2004. Smoking during pregnancy continued to decline. No improvement was seen in the timely initiation of prenatal care. The cesarean delivery rate jumped 6 percent to another all-time high, whereas the rate of vaginal birth after previous cesarean fell by 13 percent. Preterm and low birthweight rates continued their steady rise. The twinning rate increased, but the rate of triplet and higher order multiple births was down slightly.

Births: final data for 2003.

OBJECTIVES: This report presents 2003 data on U.S. births according to a wide variety of characteristics. Data are presented for maternal demographic characteristics including age, live-birth order, race, Hispanic origin, marital status, and educational attainment; maternal characteristics (medical risk factors, weight gain, and tobacco and alcohol use); medical care utilization by pregnant women (prenatal care, obstetric procedures, complications of labor and/or delivery, attendant at birth, and method of delivery); and infant characteristics (period of gestation, birthweight, Apgar score, abnormal conditions, congenital anomalies, and multiple births). Also presented are birth and fertility rates by age, live-birth order, race, Hispanic origin, and marital status. Selected data by mother's State of residence are shown, as well as data on month and day of birth, sex ratio, and age of father. Trends in fertility patterns and maternal and infant characteristics are described and interpreted. METHODS: Descriptive tabulations of data reported on the birth certificates of the 4.09 million births that occurred in 2003 are presented. Denominators for population-based rates are derived from the U.S. 2000 census. RESULTS: In 2003 there were 4,089,950 live births reported in the United States, 2 percent more than the number in 2002. The crude birth rate (CBR) and general fertility rate (GFR) rose slightly. Childbearing among teenagers declined for the 12th straight year to another historic low. Birth rates for women aged 20-24 years also declined, whereas rates for women aged 25-44 years increased 2-6 percent, reaching highs not reported since the mid- to late 1960s. All measures of unmarried childbearing increased considerably in 2003, but smoking during pregnancy continued to decline. Timely initiation of prenatal care improved slightly. The cesarean delivery rate jumped another 5 percent to another all-time high, and the rate of vaginal birth after previous cesarean dropped 16 percent, an all-time low. Key measures of birth outcome-the percentages of preterm and low birthweight (LBW) births-rose. The twinning rate increased, but the rate of triplet and higher order multiple births was essentially stable.
