Annual summary of vital statistics: 2012-2013.

The number of births in the United States declined by 1% between 2012 and 2013, to a total of 3 932 181. The general fertility rate also declined 1% to 62.5 births per 1000 women, the lowest rate ever reported. The total fertility rate was down by 1% in 2013 (to 1857.5 births per 1000 women). The teenage birth rate fell to another historic low in 2013, 26.5 births per 1000 women. Birth rates also declined for women 20 to 29 years, but the rates rose for women 30 to 39 and were unchanged for women 40 to 44. The percentage of all births that were to unmarried women declined slightly to 40.6% in 2013, from 40.7% in 2012. In 2013, the cesarean delivery rate declined to 32.7% from 32.8% for 2012. The preterm birth rate declined for the seventh straight year in 2013 to 11.39%; the low birth weight (LBW) rate was essentially unchanged at 8.02%. The infant mortality rate was 5.96 infant deaths per 1000 live births in 2013, down 13% from 2005 (6.86). The age-adjusted death rate for 2013 was 7.3 deaths per 1000 population, unchanged from 2012. Crude death rates for children aged 1 to 19 years declined to 24.0 per 100 000 population in 2013, from 24.8 in 2012. Unintentional injuries and suicide were, respectively, the first and second leading causes of death in this age group. These 2 causes of death jointly accounted for 45.7% of all deaths to children and adolescents in 2013.

Five-year follow-up of Community Pediatrics Training Initiative.

OBJECTIVE: To compare community involvement of pediatricians exposed to enhanced residency training as part of the Dyson Community Pediatrics Training Initiative (CPTI) with involvement reported by a national sample of pediatricians. METHODS: A cross-sectional analyses compared 2008-2010 mailed surveys of CPTI graduates 5 years after residency graduation with comparably aged respondents in a 2010 mailed national American Academy of Pediatrics survey of US pediatricians (CPTI: n = 234, response = 56.0%; national sample: n = 243; response = 59.9%). Respondents reported demographic characteristics, practice characteristics (setting, time spent in general pediatrics), involvement in community child health activities in past 12 months, use of ≥1 strategies to influence community child health (eg, educate legislators), and being moderately/very versus not at all/minimally skilled in 6 such activities (eg, identify community needs). χ(2) statistics assessed differences between groups; logistic regression modeled the independent association of CPTI with community involvement adjusting for personal and practice characteristics and perspectives regarding involvement. RESULTS: Compared with the national sample, more CPTI graduates reported involvement in community pediatrics (43.6% vs 31.1%, P < .01) and being moderately/very skilled in 4 of 6 community activities (P < .05). Comparable percentages used ≥1 strategies (52.2% vs 47.3%, P > .05). Differences in involvement remained in adjusted analyses with greater involvement by CPTI graduates (adjusted odds ratio 2.4, 95% confidence interval 1.5-3.7). CONCLUSIONS: Five years after residency, compared with their peers, more CPTI graduates report having skills and greater community pediatrics involvement. Enhanced residency training in community pediatrics may lead to a more engaged pediatrician workforce.

Annual summary of vital statistics: 2010-2011.

The number of births in the United States declined by 1% between 2010 and 2011, to a total of 3 953 593. The general fertility rate also declined by 1% to 63.2 births per 1000 women, the lowest rate ever reported. The total fertility rate was down by 2% in 2011 (to 1894.5 births per 1000 women). The teenage birth rate fell to another historic low in 2011, 31.3 births per 1000 women. Birth rates also declined for women aged 20 to 29 years, but the rates increased for women aged 35 to 39 and 40 to 44 years. The percentage of all births to unmarried women declined slightly to 40.7% in 2011, from 40.8% in 2010. In 2011, the cesarean delivery rate was unchanged from 2010 at 32.8%. The preterm birth rate declined for the fifth straight year in 2011 to 11.72%; the low birth weight rate declined slightly to 8.10%. The infant mortality rate was 6.05 infant deaths per 1000 live births in 2011, which was not significantly lower than the rate of 6.15 deaths in 2010. Life expectancy at birth was 78.7 years in 2011, which was unchanged from 2010. Crude death rates for children aged 1 to 19 years did not change significantly between 2010 and 2011. Unintentional injuries and homicide were the first and second leading causes of death, respectively, in this age group. These 2 causes of death jointly accounted for 47.0% of all deaths of children and adolescents in 2011.

A new framework for childhood health promotion: the role of policies and programs in building capacity and foundations of early childhood health.

Although the connection between early life experiences and later health is becoming increasingly clear, what is needed, now, is a new organizing framework for childhood health promotion, grounded in the latest science. We review the evidence base to identify the steps in the overall pathway to ensuring better health for all children. A key factor in optimizing health in early childhood is building capacities of parents and communities. Although often overlooked, capacities are integral to building the foundations of lifelong health in early childhood. We outline a framework for policymakers and practitioners to guide future decision-making and investments in early childhood health promotion.

Annual summary of vital statistics: 2009.

The number of births in the United States decreased by 3% between 2008 and 2009 to 4 130 665 births. The general fertility rate also declined 3% to 66.7 per 1000 women. The teenage birth rate fell 6% to 39.1 per 1000. Birth rates also declined for women 20 to 39 years and for all 5-year groups, but the rate for women 40 to 44 years continued to rise. The percentage of all births to unmarried women increased to 41.0% in 2009, up from 40.6% in 2008. In 2009, 32.9% of all births occurred by cesarean delivery, continuing its rise. The 2009 preterm birth rate declined for the third year in a row to 12.18%. The low-birth-weight rate was unchanged in 2009 at 8.16%. Both twin and triplet and higher order birth rates increased. The infant mortality rate was 6.42 infant deaths per 1000 live births in 2009. The rate is significantly lower than the rate of 6.61 in 2008. Linked birth and infant death data from 2007 showed that non-Hispanic black infants continued to have much higher mortality rates than non-Hispanic white and Hispanic infants. Life expectancy at birth was 78.2 years in 2009. Crude death rates for children and adolescents aged 1 to 19 years decreased by 6.5% between 2008 and 2009. Unintentional injuries and homicide, the first and second leading causes of death jointly accounted for 48.6% of all deaths to children and adolescents in 2009.

Annual summary of vital statistics: 2008.

The number of births in the United States decreased between 2007 and 2008 (preliminary estimate: 4 251 095). Birth rates declined among all women aged 15 to 39 years; the decrease among teenagers reverses the increases seen in the previous 2 years. The total fertility rate decreased 2% in 2008 to 2085.5 births per 1000 women. The proportion of all births to unmarried women increased to 40.6% in 2008, up from 39.7% in 2007. The 2008 preterm birth rate was 12.3%, a decline of 3% from 2007. In 2008, 32.3% of all births occurred by cesarean delivery, up nearly 2% from 2007. Twin and triplet birth rates were unchanged. The infant mortality rate was 6.59 infant deaths per 1000 live births in 2008 (significantly lower than the rate of 6.75 in 2007). Life expectancy at birth was 77.8 years in 2008. Crude death rates for children aged 1 to 19 years decreased by 5.5% between 2007 and 2008. Unintentional injuries and homicide were, respectively, the first and second leading causes of death in this age group. These 2 causes of death jointly accounted for 51.2% of all deaths of children and adolescents in 2008. This annual article is a long-standing feature in Pediatrics and provides a summary of the most current vital statistics data for the United States. We also include a special feature this year on the differences in cesarean-delivery rates according to race and Hispanic origin.

In the shadow of academic medical centers: a systematic review of urban health research in Baltimore City.

The city of Baltimore is a typical, large, urban center in the United States with several major academic medical institutions surrounded by disadvantaged neighborhoods with multiple poor health indices. In order to understand the extent to which academic research agendas reflect the health concerns of Baltimore's local population, a systematic review was conducted to identify research about four key, health-related topic areas. We classified papers on: disease prevalence and health status, utilization of health services, population-based interventions, and the unmet health needs of Baltimore City residents. Approximately 4,150 citations were identified in the search and two levels of screening yielded a total of 288 papers. The majority of articles (n = 189) examined prevalence of health conditions such as Human Immunodeficiency Virus (HIV), mental health and mental disorders, and sexually transmitted diseases. Papers about specific target populations focused primarily on adults, African Americans, and females. Despite a significant body of research concerning several health conditions and priority populations, significant gaps in knowledge about health services utilization, community interventions, unmet health needs, and the prevalence of specific health issues remain. This review provides valuable insight into the extent of health research conducted about the city of Baltimore and whether community health priorities have been investigated. It provides a basis for examining the potential directions of academic research centers to effectively identify and address collective, urban health priorities of the communities in which they reside.

Effectiveness of an educational intervention on complementary feeding practices and growth in rural China: a cluster randomised controlled trial.

OBJECTIVE: Inappropriate complementary feeding is one of the major causes of malnutrition in young children in developing countries. We developed an educational intervention, delivered by local health-care providers, aimed at improving complementary feeding practices and child nutrition. DESIGN: Eight townships in Laishui, a rural area in China, were randomly assigned to the educational intervention or control group. A total of 599 healthy infants were enrolled at age 2-4 months and followed up until 1 year of age. In the intervention group, educational messages and enhanced home-prepared recipes were disseminated to caregivers through group trainings and home visits. Questionnaire surveys and anthropometric measurements were taken at baseline and ages 6, 9 and 12 months. Analysis was by intention to treat. RESULTS: It was found that food diversity, meal frequency and hygiene practices were improved in the intervention group. Infants in the intervention group gained 0.22 kg more weight (95 % CI 0.003, 0.45 kg, P = 0.047) and gained 0.66 cm more length (95 % CI 0.03, 1.29 cm, P = 0.04) than did controls over the study period. CONCLUSIONS: Findings from the study suggest that an educational intervention delivered through local health-care providers can lead to substantial behavioural changes of caregivers and improve infant growth.

Annual summary of vital statistics: 2007.

The number of births in the United States increased between 2006 and 2007 (preliminary estimate of 4,317,119) and is the highest ever recorded. Birth rates increased among all age groups (15 to 44 years); the increase among teenagers is contrary to a long-term pattern of decline during 1991-2005. The total fertility rate increased 1% in 2007 to 2122.5 births per 1000 women. This rate was above replacement level for the second consecutive year. The proportion of all births to unmarried women increased to 39.7% in 2007, up from 38.5% in 2006, with increases noted for all race and Hispanic-origin groups and within each age group of 15 years and older. In 2007, 31.8% of all births occurred by cesarean delivery, up 2% from 2006. Increases in cesarean delivery were noted for most age groups and for non-Hispanic white, non-Hispanic black, and Hispanic women. Multiple-birth rates, which rose rapidly over the last several decades, did not increase during 2005-2006. The 2007 preterm birth rate was 12.7%, a decline of 1% from 2006. The low-birth-weight rate also declined in 2007 to 8.2%. The infant mortality rate was 6.77 infant deaths per 1000 live births in 2007, which is not significantly different from the 2006 rate. Non-Hispanic black infants continued to have much higher rates than non-Hispanic white and Hispanic infants. States in the southeastern United States had the highest infant and fetal mortality rates. The United States continues to rank poorly in international comparisons of infant mortality. Life expectancy at birth reached a record high of 77.9 years in 2007. Crude death rates for children aged 1 to 19 years decreased by 2.5% between 2006 and 2007. Unintentional injuries and homicide were the first and second leading causes of death, respectively, accounting for 53.7% of all deaths to children and adolescents in 2007.

Early childhood health promotion and its life course health consequences.

OBJECTIVE: To explore whether health promotion efforts targeted at preschool-age children can improve health across the life span and improve future economic returns to society. METHODS: We selected 4 health topics to review-tobacco exposure, unintentional injury, obesity, and mental health-because they are clinically and epidemiologically significant, and represent the complex nature of health problems in this early period of life. The peer-reviewed literature was searched to assess the level of evidence for short- and long-term health impacts of health promotion and disease prevention interventions for children from before birth to age 5. This review sought to document the monetary burden of poor child health, the cost implications of preventing and treating child health problems, and the net benefit of the interventions. RESULTS: The evidence is compelling that these 4 topics-tobacco exposure, unintentional injury, obesity, and mental health-constitute a significant burden on the health of children and are the early antecedents of significant health problems across the life span. The evidence for the cost consequences of these problems is strong, although more uneven than the epidemiological data. The available evidence for the effectiveness of interventions in this age group was strongest in the case of preventing tobacco exposure and injuries, was limited to smaller-scale clinical interventions in the case of mental health, and was least available for efforts to prevent obesity among preschoolers. CONCLUSIONS: Currently available research justifies the implementation of health interventions in the prenatal to preschool period-especially to reduce tobacco exposure and prevent injuries. There is an urgent need for carefully targeted, rigorous research to examine the longitudinal causal relationships and provide stronger economic data to help policy makers make the case that the entire society will benefit from wise investment in improving the health of preschool-age children and their families.

Risk factors for unintentional injuries in children: are grandparents protective?

OBJECTIVE: We sought to identify sociodemographic and familial correlates of injury in children aged 2 to 3 years. METHODS: The Healthy Steps data set describes 5565 infants who were enrolled at birth in 15 US cities in 1996-1997 and had follow-up until they were 30 to 33 months of age. Data were linked to medical claims reporting children's medically attended office visits by age 30 to 33 months. Each claim was accompanied by a reason for the visit. An analytical sample of 3449 was derived from the children who could be effectively followed up and linked to medical charts. Missing data were imputed by using multiple imputation with chained equations. The analytical sample showed no systematic evidence of sample selection bias. Multivariate logistic regression was used to determine the odds ratios of injury events. RESULTS: Odds of medically attended injuries were decreased for children who received care from grandparents. Odds were increased for children who lived where fathers did not co-reside or in households where the parents never married. Statistical results were robust to the addition of a variety of covariates such as income, education, age, gender, and race. CONCLUSIONS: Children are at higher risk for medically attended injury when their parents are unmarried. Having grandparents as caregivers seems to be protective. Household composition seems to play a key role in placing children at risk for medically attended injuries.

Breastfeeding in rural China: association between knowledge, attitudes, and practices.

Breastfeeding rates have decreased in the past decade in China. This study identifies psychosocial and sociodemographic factors associated with breastfeeding practices. A total of 599 mothers of infants 2 to 4 months old were interviewed using a structured questionnaire. Nearly all infants (95.5%) were breastfed, but only 4.2% were exclusively breastfed, and 48.7% were fully breastfed. Mothers' intention to breastfeed (odds ratio [OR] = 1.67, 95% CI: 1.39-2.01) and social support (OR = 1.22, 95% CI: 1.002-1.50) were associated with full breastfeeding. Full breastfeeding prevalence decreased with children's age (OR = 0.79, 95% CI: 0.63, 0.98). Girls were more likely to be fully breastfed than boys (OR = 1.46, 95% CI: 1.06, 2.02). This study found that optimal breastfeeding practices during the first 4 months of life are not universal in rural China. Health care providers should be more actively involved in educating and motivating mothers and their family members to adopt optimal breastfeeding practices.

The changing pattern of doctoral education in public health from 1985 to 2006 and the challenge of doctoral training for practice and leadership.

We examined trends in doctoral education in public health and the challenges facing practice-oriented doctor of public health (DrPH) programs. We found a rapid rise in the numbers of doctoral programs and students. Most of the increase was in PhD students who in 2006 composed 73% of the total 5247 current public health doctoral students, compared with 53% in 1985. There has also been a substantial increase (40%) in students in DrPH programs since 2002. Challenges raised by the increased demand for DrPH practice-oriented education relate to admissions, curriculum, assessment processes, and faculty hiring and promotion. We describe approaches to practice-based doctoral education taken by three schools of public health.

Annual summary of vital statistics: 2006.

US births increased 3% between 2005 and 2006 to 4,265,996, the largest number since 1961. The crude birth rate rose 1%, to 14.2 per 1000 population, and the general fertility rate increased 3%, to 68.5 per 1000 women 15 to 44 years. Births and birth rates increased among all race and Hispanic-origin groups. Teen childbearing rose 3% in 2006, to 41.9 per 1000 females aged 15 to 19 years, the first increase after 14 years of steady decline. Birth rates rose 2% to 4% for women aged 20 to 44; rates for the youngest (10-14 years) and oldest (45-49) women were unchanged. Childbearing by unmarried women increased steeply in 2006 and set new historic highs. The cesarean-delivery rate rose by 3% in 2006 to 31.1% of all births; this figure has been up 50% over the last decade. Preterm and low birth weight rates also increased for 2006 to 12.8% and 8.3%, respectively. The 2005 infant mortality rate was 6.89 infant deaths per 1000 live births, not statistically higher than the 2004 level. Non-Hispanic black newborns continued to be more than twice as likely as non-Hispanic white and Hispanic infants to die in the first year of life in 2004. For all gender and race groups combined, expectation of life at birth reached a record high of 77.9 years in 2005. Age-adjusted death rates in the United States continue to decline. The crude death rate for children aged 1 to 19 years decreased significantly between 2000 and 2005. Of the 10 leading causes of death for children in 2005, only the death rate for cerebrovascular disease was up slightly from 2000, whereas accident and chronic lower respiratory disease death rates decreased. A large proportion of childhood deaths, however, continue to occur as a result of preventable injuries.

Healthy Steps for Young Children: sustained results at 5.5 years.

OBJECTIVE: We sought to determine whether Healthy Steps for Young Children has sustained treatment effects at 5.5 years, given early findings demonstrating enhanced quality of care and improvements in selected parenting practices. METHODS: Healthy Steps was a clinical trial that incorporated developmental specialists and enhanced developmental services into pediatric care in the first 3 years of life. A total of 5565 children were enrolled at birth and followed through 5.5 years. Healthy Steps was evaluated at 6 randomization and 9 quasi-experimental sites. Computer-assisted telephone interviews were conducted with mothers when Healthy Steps children were 5.5 years of age. Outcomes included experiences seeking care, parent response to child misbehavior, perception of child's behavior, and parenting practices to promote development and safety. Logistic regression was used to estimate overall effects of Healthy Steps, adjusting for site and baseline demographic characteristics. RESULTS: A total of 3165 (56.9%) families responded to interviews (usual care: n = 1441; Healthy Steps: n = 1724). Families that had received Healthy Steps services were more satisfied with care (agreed that pediatrician/nurse practitioner provided support, 82.0% vs 79.0%; odds ratio: 1.25 [95% confidence interval: 1.02-1.53]) and more likely to receive needed anticipatory guidance (54.9% vs 49.2%; odds ratio: 1.33 [95% confidence interval: 1.13-1.57]) (all P < .05). They also had increased odds of remaining at the original practice (65.1% vs 61.4%; odds ratio: 1.19 [95% confidence interval: 1.01-1.39]). Healthy Steps families reported reduced odds of using severe discipline (slap in face/spank with object, 10.1% vs 14.1%; odds ratio: 0.68 [95% confidence interval: 0.54-0.86]) and increased odds of often/almost always negotiating with their child (59.8% vs 56.3%; odds ratio: 1.20 [95% confidence interval: 1.03-1.39]). They had greater odds of reporting a clinical or borderline concern regarding their child's behavior (18.1% vs 14.8%; odds ratio: 1.35 [95% confidence interval: 1.10-1.64]) and their child reading books (59.4% vs 53.6%; odds ratio: 1.16 [95% confidence interval: 1.00-1.35]). There were no effects on safety practices. CONCLUSIONS: Sustained treatment effects, albeit modest, are consistent with early findings. Universal, practice-based interventions can enhance quality of care for families with young children and can improve selected parenting practices beyond the duration of the intervention.

Rising infant mortality in Delaware: an examination of racial differences in secular trends.

OBJECTIVES: Recent increases in the Delaware Infant Mortality Rate (IMR) have been attributed to a rise in the mortality of very low birth weight (VLBW, <1500 g) infants born to mothers of higher socioeconomic status. This study examines whether the determinants of infant mortality trends in Delaware vary by race. METHODS: Linked birth/infant death cohort files for the two periods 1993-1997 and 1998-2002 were used to evaluate the determinants of infant mortality trends separately for White and Black racial groups. Kitagawa analyses determined the components of race-specific infant mortality trends attributable to changes in both the birthweight distribution and birthweight-specific mortality rates. Maternal characteristics were examined to identify factors associated with IMR changes. RESULTS: Between the two time periods, infant mortality increased 23% among White infants and 17% among Black infants. For both races, the infant mortality increase was explained by increases in the incidence and mortality of VLBW infants, specifically below <500 grams for Blacks and <1,000 grams for Whites. The increased incidence of VLBW deliveries was statistically significant only among Whites, almost 40% of which was explained by an increase in multiple births. For both Whites and Blacks, the increase in VLBW mortality occurred mainly among births to more traditionally advantaged women who were twenty or older, at least high school educated, married, privately insured, had received first trimester prenatal care, and those who delivered multiple births. CONCLUSIONS: These findings suggest that conventional strategies of increasing access to prenatal care among disadvantaged women may be insufficient to reverse recent IMR increases in Delaware, irrespective of race. Future efforts should focus on understanding the causes of the increased infant mortality associated with higher socioeconomic status, including changes in assisted reproductive technology utilization, maternal health status, and obstetric practice.

Annual summary of vital statistics: 2005.

The general fertility rate in 2005 was 66.7 births per 1000 women aged 15 to 44 years, the highest level since 1993. The birth rate for teen mothers (aged 15 to 19 years) declined by 2% between 2004 and 2005, falling to 40.4 births per 1000 women, the lowest ever recorded in the 65 years for which there are consistent data. The birth rates for women > or = 30 years of age rose in 2005 to levels not seen in almost 40 years. Childbearing by unmarried women also increased to historic record levels for the United States in 2005. The cesarean-delivery rate rose by 4% in 2005 to 30.2% of all births, another record high. The preterm birth rate continued to rise (to 12.7% in 2005), as did the rate for low birth weight births (8.2%). The infant mortality rate was 6.79 infant deaths per 1000 live births in 2004, not statistically different from the rate in 2003. Pronounced differences in infant mortality rates by race and Hispanic origin continue, with non-Hispanic black newborns more than twice as likely as non-Hispanic white and Hispanic infants to die within 1 year of birth. The expectation of life at birth reached a record high in 2004 of 77.8 years for all gender and race groups combined. Death rates in the United States continued to decline, with death rates decreasing for 9 of the 15 leading causes. The crude death rate for children aged 1 to 19 years did not decrease significantly between 2003 and 2004. Of the 10 leading causes of death for 2004 in this age group, only the rates for influenza and pneumonia showed a significant decrease. The death rates increased for intentional self-harm (suicide), whereas rates for other causes did not change significantly for children. A large proportion of childhood deaths continue to occur as a result of preventable injuries.
