Biopsychosocial Determinants of Sleep and Wellbeing for Teens in FFCWS

Principal Investigators: Lauren Hale and Orfeu Buxton

Funder: National Institutes of Health (5R01HD073352)

Approximately 1,000 teens completing phone surveys during the Year 15 follow-up wave of FFCWS wore wrist and hip actigraphs for a one-week period following the home visit.  This actigraphic data allowed researchers to directly monitor sleep timing, duration, and quality in addition to physical activity. During this same week, participants provided a one-week multimedia exposure diary. Together, these measures will allow researchers to study the biopsychosocial (e.g., socioeconomic status, neighborhood factors, genetic) determinants of adolescent sleep patterns and their associations with biological (i.e., obesity) and psychological (i.e., depression) outcomes.  Researchers will also be using this data to study the direct and indirect effects of physical activity and screen time exposure on adolescent sleep, health, and wellbeing. 

Adolescent Wellbeing and Brain Development

Principal Investigators: Colter Mitchell, Christopher Monk, and Luke Hyde

Funder: National Institutes of Health (5R01MH103761)

Following the completion of the Year 15 core home visit activities, teens in the FFCWS sample cities of Detroit and Toledo were asked to participate in a ½ day session of additional activities at the University of Michigan, including brain scan, measurement of cortisol reactivity, collection of hair, blood spots, and saliva, as well as clinical interviews and videotaping.  Researchers are studying the relationship between poverty-related stress and affective function at four levels of analysis: brain, physiological, behavioral, and self/parent report measures.  A major aim of this research is better characterize mental health conditions that result from poverty-related stress -- by identifying the mechanisms through which this stress alters brain and hypothalamic-pituitary-adrenal (HPA) axis function. 

Adolescents underwent 1) functional MRI to assess activation and connectivity during an emotional faces task, a monetary reward task, and rest, and 2) diffusion MRI to measure structural connectivity. For the emotional faces task, participants viewed angry, fearful, happy, sad, and neutral faces and indicated the gender of the face while pressing a button. For the monetary reward task, participants quickly responded to a visual stimulus to gain or avoid losing money, allowing measurement of anticipation, response, and outcome to monetary incentive. This data can be accessed through the NIMH Data Archive.  


Principal Investigators: Rachel Goldberg and Marta Tienda

Funder: The Center for Health and Wellbeing, Princeton University

The mDiary study followed a subsample of teens who have completed core surveys in the Year 15 follow-up of FFCWS.  Teens used a smart phone application or a web browser to complete bi-weekly surveys, which ask about family, peer group, and romantic relationships. There were also questions about the teen’s mood, school experiences, substance and time use, and expectations for the future.

The Fragile Families Challenge: A Scientific Mass Collaboration to Improve the Lives of Disadvantaged Children in the United States

Principal Investigator:  Matthew Salganik

Funder:  Russell Sage Foundation

This project assembled a multidisciplinary pool of hundreds of social scientists and computer scientists to work independently and in teams to build statistical models to predict a set of policy-relevant adolescent and family outcomes (including grit, GPA, material hardship, eviction, job layoff, and job training) measured from the Year 15 wave of the Fragile Families and Child Wellbeing Study. Over 150 research teams from 68 institutions in 7 countries used rich survey data covering 2,121 training observations on 12,942 variables to produce predictive models that together set a benchmark of predictive performance for outcomes identified by social scientists as important factors in the status attainment process.

Parental Resources and Child Wellbeing

Principal Investigators: Christina Paxson, Robert Whitaker, Robert Kahn, Sara McLanahan, Anne Case

Funder: National Institutes of Health-SEED

The overall aim of this project is to study how parental resources affect children’s wellbeing, as measured by children’s health status and their cognitive, social, and emotional development. Our approach will be to examine how three broadly defined aspects of parental resources – economic status, family structure, and parental health (both mental and physical) – are related to each other. We will then examine how these parental resources affect the quality of parenting (discipline, warmth, supervision, and cognitive stimulation) and material resources (e.g., home learning materials, food security, neighborhood safety, and access to medical care) that children receive. Finally we will define how all of these “inputs,” in turn, affect children’s outcomes. As a specific “case study” we will study determinants of childhood obesity, a preventable child health outcome that is the precursor of adult obesity. The study utilizes data collected from FFCWS, from birth to age four. A key advantage of this survey is that it tracks and collects information from fathers, including those who do not live with their children. Using FFCWS data, we studied the role of fathers in children’s health and developmental outcomes. FFCWS data will be supplemented with data from the Panel Study of Income Dynamics and the National Health Interview Survey. The results of this research will provide valuable information on the determinants of children’s wellbeing, and the mechanisms through which parental resources affect children’s outcomes.

Economic Status, Public Policy and Child Neglect

Principal Investigators: Christina Paxson, Jeanne Brooks-Gunn, Jane Waldfogel, Neil Guterman
(funds the In-Home Longitudinal Study of Pre-School Aged Children)

Funders: Eunice Kennedy Shriver National Institute of Child Health & Human Development and National Institute of Mental Health

The aim of this project is to study the relationships between economic factors and child neglect. The research will investigate how parental resources, in the form of parental presence or absence, time, and money, affect both physical and emotional neglect of children under the age of five. The work will also examine how parental resources interact with other factors that affect child neglect, including parental stress and depression, and community characteristics such as community poverty, neighborhood cohesion, social control and violence. A major focus of the research will be the effects on neglect of public policies, such as welfare programs and child support enforcement, which influence parental resources. A special neglect module was added to the in-home assessments of FFCWS when the children under study were 30 and 60 months old. The assessments provide first-hand information on the child's physical environment and the quality of parenting and parent-child interactions. The information from the neglect module, when combined with the extensive socioeconomic data from FFCWS will be a unique and valuable resource for the study of child neglect.

Fatherhood and Incarceration in FFCWS

Principal Investigator: Bruce Western

Funder: Mott Foundation

Previous research often finds that incarceration reduces male earnings. But the estimated magnitudes of the effect vary widely and the causal mechanisms are not well understood because of the inadequacy of existing data. The two strongest national data sources for studying the impact of incarceration on employment do not provide detailed and accurate information. The main survey source, the NLSY, has not accurately measured incarceration over time. The main administrative data source, the FPSSIS, contains little demographics or labor market information about offenders. What is needed are data that provide: 1) a population based sample with a large sample of ex-convicts, 2) detailed information about labor market status and its demographic and ecological determinants, and 3) detailed information about contact over time with the criminal justice system. The FFCWS already meets the first two criteria. We added a criminal justice history module to the first three follow-up interviews in the study and conduct analyses with these data to obtain improved estimates of the magnitude of the labor market penalty for incarceration and a better understanding of the causal mechanisms.

Child Care & Parental Employment in FFCWS

Principal Investigators: Jeanne Brooks-Gunn, Deborah Phillips, and Sara McLanahan

Funder: Eunice Kennedy Shriver National Institute of Child Health & Human Development

This project added a child care module to the FFCWS. Using a sample of 2,176 children from 18 cities across the country, we included child care observations and interviews with providers and parents when the children are 33-months of age. We also assessed child cognitive, social and emotional development, as well as parental practices and behaviors during home visits at 30- and 60-months. This project involved contacting teachers across all 18 cities to obtain information regarding the children's kindergarten experiences. Our specific aims are to: (1) describe parental employment and child care patterns in a diverse sample of low-income families; (2) assess the relative influences of employment, child care, and family context on child well-being; (3) augment these models by examining possible moderating child and family factors; and (4) see whether changes in employment, child care, and family context predict changes in children's cognitive, social, and emotional well-being.

FFCWS and Public Policy: Fathers' Ties to Unmarried Mothers and Their Children*

Principal Investigator: Maureen Waller

Funder: PPIC

This project uses information from FFCWS and qualitative interviews conducted with African American, white, and Hispanic parents who participated in the Oakland survey to examine early relationships in fragile families. The study's aim was to describe the dynamics of relationships between unmarried parents and between unmarried fathers and their children during the first years of the children's lives. This analysis focused on the obstacles parents experience in forming stable romantic and parenting relationships and how social policies are related to decisions about cohabitation, marriage, and paternal involvement.

*The sample for this study is Oakland, California

Religion and Relationships in Urban America

Principal Investigators: W. Bradford Wilcox and Byron Johnson

Funder: The Center for Research on Religion and Urban Civil Society (CRRUCS) at the University of Pennsylvania

Religious behavior and religious beliefs are associated with higher levels of relationship quality and stability in the population at large. But we know little about how religion influences the relationships of romantically-involved, cohabiting, and married couples in urban America. This project investigated the effect of religion on union formation, relationship quality, union stability, and domestic violence. This project also focused on the ways in which particular relationship-related beliefs and practices mediate the associations between religion and relationships.

Fragile Families and Child Health

Principal Investigators: Nancy Reichman and Julien Teitler

Funder: Eunice Kennedy Shriver National Institute of Child Health & Human Development

Child health is the product of a complex web of socio-demographic, prenatal, family and neighborhood factors. Yet few nationally representative datasets contain measures from all of these domains. We proposed to augment the national FFCWS data with medical records information and neighborhood measures to create an unparalleled resource for addressing important questions about the health of children, particularly those in high-risk families. We used the enhanced data to describe infant and child health in the United States and construct risk profiles highly associated with poor child health.

Couple Dynamics & Fathers' Investments in Children: A Qualitative Addition

Principal Investigators: Kathryn Edin and Paula England

Funder: MacArthur Foundation

The TLC3 project conducted qualitative in-depth interviews with a subset of parents from the FFCWS sample. These data enabled us to analyze why some couples with very young children break up while others remain together, why some fathers remain actively involved in their parent role while others do not, and how couple and parenthood dynamics early in a child's life affect that child's development.

Transitions to Adulthood

Principal Investigator: MacArthur Network on Young Adult Transitions

Funder: MacArthur Foundation

The Transitions to Adulthood project added new questions to FFCWS. These new questions will extend our information on (1) race, ethnicity, and nationality, (2) access to community programs that support new parents, (3) knowledge of public policies such as TANF, childcare, child support, (4) fertility histories, and (5) family of origin histories. The new questions will make the data more useful for studying how "high risk" parents cope (successfully and unsuccessfully) with the transition to parenthood under difficult conditions, and how individual, couple, family, and environmental factors promote or retard successful development.

Mexican American Child Health: Birth to Early Childhood

Principal Investigator: Yolanda C. Padilla

Funder:  Eunice Kennedy Shriver National Institute of Child Health & Human Development 

In spite of the relatively favorable birth outcomes among Mexican Americans in comparison to other US racial and ethnic groups, a growing body of evidence indicates that Mexican American children experience disproportionately higher rates of health problems and developmental deficiencies during their early years of life. Known as the epidemiologic paradox, the phenomenon of relatively healthy birth outcomes among Mexican Americans, in spite of high poverty rates and low levels of prenatal care utilization, has been extensively studied, but very little research on this population has been extended to early childhood health and development outcomes. Few researchers have looked beyond birth outcomes to the effects of current social risk factors that include social environment and access to adequate health care, on early childhood health and development among Mexican Americans. One important reason for this gap in knowledge has been the lack of detailed data to simultaneously consider the wide range of potential explanatory variables across time. Therefore, the overall goal of this project is to identify the factors that influence the health and development of Mexican American children from birth through age 5 and to do so in a comparative context with the non-Hispanic white and non-Hispanic black populations. A particular goal of this study is to investigate how hypothesized protective factors present during pregnancy may or may not continue to sustain the health and development of Mexican American children beyond birth. We will examine three sets of outcomes: (a) birth outcomes, (b) child health and well-child health care, and (c) child development. Although we expect that the determinants of each of the outcomes are related, the analyses will be based on relevant conceptual models applicable to each specific outcome. Our statistical analyses will also allow us to consider the interconnections between birth outcomes, health and health care, and development in the course of early childhood. We used national- level data from FFCWS to conduct these analyses. FFCWS is a large, nationally representative longitudinal survey of a birth cohort of approximately 4800 children, including approximately 750 Mexican Americans, with births to unmarried parents substantially over-sampled. The data are exceptionally rich in comparison to others which have been used to study Mexican American child health and development, allowing us a unique opportunity to more fully understand the range of factors that influence child well being within this rapidly growing population.

Childcare Centers and Social Capital

Principal Investigator: Mario Luis Small

Funders: Princeton University and Eunice Kennedy Shriver National Institute of Child Health & Human Development

This study examined whether and how childcare centers, as neighborhood institutions, help low-income parents gain access to social capital. The study examined whether and how the poor use centers to develop social support networks; to buffer against the effects of joblessness or underemployment; and to gain access to health care, dental care, and various subsidized services through the centers’ inter-organizational networks. The project combined qualitative and quantitative methods and collects data at the center and individual levels. The study includes four major data sources: (1) FFCWS, to which questions were added on networks, resources, and childcare centers; (2) a random telephone survey of 293 private and public childcare centers in New York City; (3) an in-depth field study of 24 childcare centers in four New York City neighborhoods: one poor and predominantly black, one poor and predominantly white, one poor and predominantly Latino, and one upper-middle class; and (4) an in-depth interviews with approximately 70 parents in a selection of the centers.

Family Structure, Parenting and Child Wellbeing

Principal Investigator: Marcia J. Carlson

Funder: K01 grant from the Eunice Kennedy Shriver National Institute of Child Health & Human Development

This 5-year project uses data from FFCWS to examine linkages among family structure, mother-father relationships, father involvement, and child wellbeing for a cohort of children born outside of marriage. Sometimes referred to as "fragile families," these parents and children are at greater risk of poverty and family dissolution than families in which childbearing is preceded by marriage. This study was designed to provide new information about family relationships and dynamics among unmarried parents and their children in order to strengthen programs and public policy.

Effects of Child Health on Family Resources

Principal Investigators: Nancy E. Reichman, Hope Corman, and Kelly Noonan

Funder: Eunice Kennedy Shriver National Institute of Child Health & Human Development

This project used augmented data from the national FFCWS sample of mostly unwed parents to estimate the effects of poor infant and child health on a broad array of family, financial, and community resources available to the child (parental relationships, household composition, subsequent fertility, parents' employment, child care arrangements, subsequent education, receipt of public assistance, child support, use of pediatric health care, and the child's participation in preschool programs). It also compared resources available to children with and without serious health problems and compare health outcomes of children at age 5 by both their health status in infancy and the resources they received during their first 5 years.

Effects of Prenatal Care on Pediatric Health Care

Principal Investigator: Nancy E. Reichman 

Funder: Eunice Kennedy Shriver National Institute of Child Health & Human Development

Most research on the effectiveness of prenatal care has focused on birth outcomes--usually birthweight or infant mortality--and has found small or no effects. However, the focus on birth outcomes represents a relatively narrow view of the potential of prenatal care. To more fully assess the benefits of prenatal care, it is necessary to consider longer-term impacts. Very little is known about the effects of prenatal care on pediatric health care utilization, health-related parenting behaviors, or child health outcomes. The few existing studies do not address the potential endogeneity of prenatal care use. These knowledge gaps are being addressed in this research project.
