Pregnancy loss is related to body mass index and prediabetes in early adulthood: Findings from Add Health.

Pregnancy loss, including miscarriage and stillbirth, affects 15-20% of pregnancies in the United States (US) annually. Accumulating evidence suggests that pregnancy loss is associated with a greater cardiovascular disease (CVD) burden later in life. However, few studies have evaluated the impact of pregnancy loss on CVD risk factors in early adulthood (age <35 years).

Race/Ethnicity, Gender, and Trajectories of Depressive Symptoms Across Early- and Mid-Life Among the Add Health Cohort.

While disparities in depressive symptoms by race/ethnicity and gender have been documented, left unclear is how such status characteristics intersect to influence mental health, particularly across early life and among a diverse set of population subgroups. This study investigates how intra- and inter-individual trends in depressive symptoms unfold across a 30-year span (ages 12-42) and are structured by the intersection of race/ethnicity and gender among White, Black, Hispanic, and Asian American young adults (N = 18,566). Analyses use data from the National Longitudinal Study of Adolescent to Adult Health, a nationally representative study of adolescents who have been followed through their fourth decade of life.

The Depths of Despair Among US Adults Entering Midlife.

Objectives: To test whether indicators of despair are rising among US adults as they age toward midlife and whether this rise is concentrated among low-educated Whites and in rural areas.

Methods: We used data from the National Longitudinal Study of Adolescent to Adult Health, a nationally representative study of US adolescents in 1994. Our sample was restricted to individuals who participated in 1 or more of 5 waves (1994-2017) and self-identified as non-Hispanic White, non-Hispanic Black, or Hispanic (n = 18 446).

Contraceptive Use Among Women with Prediabetes and Diabetes in a US National Sample.

Introduction: Although elevated blood glucose is associated with adverse maternal and fetal health outcomes, evidence suggests that women with diabetes may not be receiving comprehensive reproductive health care, including family planning and preconception care. Using a population-based sample, we evaluated the relationship between contraceptive use and biomarker-identified diabetes.

Methods: This cross-sectional study used data from 5548 women in the nationally representative National Longitudinal Study of Adolescent to Adult Health (Add Health) from 2007 to 2009.

Comorbid hypertension and diabetes among U.S. women of reproductive age: Prevalence and disparities.

Aims: Diabetes is associated with significant pregnancy complications, which can be further exacerbated by comorbid hypertension. Racial/ethnic differentials in the burden of comorbid hypertension and diabetes among women of reproductive age have not been described.

Methods: Using Wave IV of the nationally representative National Longitudinal Study of Adolescent to Adult Health (Add Health), we analyzed survey and biological data from 6576 non-pregnant women who were aged 24-32 in 2007-2008.

Racial/Ethnic Disparities in Diabetes Diagnosis and Glycemic Control Among Women of Reproductive Age.

Background: Types 1 and 2 diabetes mellitus complicate pregnancies and threaten the health of women of reproductive age and their children. Among older adults, diabetes morbidity disproportionately burdens racial/ethnic minorities, but diabetes emergence among younger adults has not been as well characterized. The objective of this study was to describe the distribution of diagnosed diabetes, undiagnosed diabetes, suboptimal preconception glycemic control, and prediabetes among women of reproductive age across racial/ethnic backgrounds.

Depression and Antidepressant Use Among Asian and Hispanic Adults: Association with Immigrant Generation and Language Use.

This research investigates the psychological well-being and usage of medical treatments by Asian and Hispanic immigrant descendants. Using data from all four waves of Add Health study, this paper focuses on two outcomes: (1) depression and (2) levels of antidepressant use by race/ethnicity, immigrant generation, and linguistic acculturation levels during adulthood. Findings reveal that depression is prevalent among Mexican Americans, other Hispanics, and Asian Americans.

Testing Longitudinal Relationships Between Binge Drinking, Marijuana Use, and Depressive Symptoms and Moderation by Sex.

Purpose: Both substance use and depression are common in adolescence and often comorbid. Past research has produced conflicting results on whether there is a temporal relationship, and if so, in which direction it operates and how it may vary by sex. We examined the longitudinal associations between substance use frequency and depressive symptoms from adolescence into young adulthood and whether the associations were moderated by sex.

The reliability of in-home measures of height and weight in large cohort studies: Evidence from Add Health.

Background: With the emergence of obesity as a global health issue an increasing number of major demographic surveys are collecting measured anthropometric data. Yet little is known about the characteristics and reliability of these data.

Objectives: We evaluate the accuracy and reliability of anthropometric data collected in the home during Wave IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health), compare our estimates to national standard, clinic-based estimates from the National Health and Nutrition Examination Survey (NHANES) and, using both sources, provide a detailed anthropometric description of young adults in the United States.

Blood spot-based measures of glucose homeostasis and diabetes prevalence in a nationally representative population of young US adults.

Purpose: We investigated understudied biomarker-based diabetes among young US adults, traditionally characterized by low cardiovascular disease risk.

Methods: We examined 15,701 participants aged 24 to 32 years at Wave IV of the National Longitudinal Study of Adolescent Health (Add Health, 2008). The study used innovative and relatively noninvasive methods to collect capillary whole blood via finger prick at in-home examinations in all 50 states.

Developmental transitions in presentations of externalizing problems among boys and girls at risk for child maltreatment.

The present study examined the impact of children's maltreatment experiences on the emergence of externalizing problem presentations among children during different developmental periods. The sample included 788 youth and their caregivers who participated in a multisite, prospective study of youth at-risk for maltreatment. Externalizing problems were assessed at ages 4, 8, and 12, and symptoms and diagnoses of attention-deficit/hyperactivity disorder, oppositional defiant disorder, and conduct disorder were assessed at age 14, during interviews with youth and caregivers.

Preconception stress, birth weight, and birth weight disparities among US women.

Objectives: We examined the impact of preconception acute and chronic stressors on offspring birth weight and racial/ethnic birth weight disparities.

Methods: We included birth weights for singleton live first (n = 3512) and second (n = 1901) births to White, Mexican-origin Latina, other-origin Latina, and Black women reported at wave IV of the National Longitudinal Study of Adolescent Health (2007-2008; ages 24-32 years). We generated factor scores for preconception acute and chronic stressors from wave I (1994-1995; ages 11-19 years) or wave III (2001-2002; ages 18-26 years) for the same cohort of women.

Selected preconception health indicators and birth weight disparities in a national study.

Background: This analysis explored the effect of timing, sequencing, and change in preconception health across adolescence and young adulthood on racial/ethnic disparities in birth weight in a diverse national cohort of young adult women.

Methods: Data came from Waves I (1994-1995), III (2001-2002), and IV (2007-2008) of the National Longitudinal Study of Adolescent Health. Eligibility was restricted to all singleton live births to female non-Hispanic White, non-Hispanic Black, Mexican-origin Latina, or Asian/Pacific Islander participants (n = 3,014) occurring between the Wave III (ages 18-26 years) and IV (ages 24-32 years) interviews.

Preconception health trajectories and birth weight in a national prospective cohort.

Purpose: This study was designed to assess the relationship between birth weight and prospectively measured trajectories of preconception health across adolescence and young adulthood in a diverse national cohort of young adult women.

Methods: Data came from Waves I (1994-1995), III (2001-2002), and IV (2007-2008) of the National Longitudinal Study of Adolescent Health. Eligibility was restricted to all the singleton live births (n = 3,436) to female participants occurring between the Wave III (ages 18-26 years) and Wave IV (ages 24-32 years) interviews.

Adolescent expectations of early death predict adult risk behaviors.

Only a handful of public health studies have investigated expectations of early death among adolescents. Associations have been found between these expectations and risk behaviors in adolescence. However, these beliefs may not only predict worse adolescent outcomes, but worse trajectories in health with ties to negative outcomes that endure into young adulthood.

Trajectories of maltreatment re-reports from ages 4 to 12:: evidence for persistent risk after early exposure.

This study identified trajectories of maltreatment re-reports between ages 4 and 12 for children first referred to Child Protective Services (CPS) for maltreatment prior to age 4 and either removed from the home or assessed by a CPS intake worker as moderately or highly likely to be abused/neglected in the future, absent intervention. Participants (n = 501) were children from the Southwest and Northwest sites of the Consortium for Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). During the 8-year follow-up period, 67% of children were re-reported.

Adolescent expectations of early death predict young adult socioeconomic status.

Among adolescents, expectations of early death have been linked to future risk behaviors. These expectations may also reduce personal investment in education and training, thereby lowering adult socioeconomic status attainment. The importance of socioeconomic status is highlighted by pervasive health inequities and dramatic differences in life expectancy among education and income groups.

Psychometric properties of a youth self-report measure of neglectful behavior by parents.

Objective: This study aimed to empirically assess psychometric properties of a multi-dimensional youth self-report measure of neglectful behavior by parents.

Method: Data were gathered from 593 12-year-old youth participating in the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) consortium; 272 also had data at age 14. Youth responded to a 25-item measure of their experiences of neglect.

Discordance in national estimates of hypertension among young adults.

Background: In the United States, where coronary heart disease (CHD) is the leading cause of mortality, CHD risk assessment is a priority and accurate blood pressure (BP) measurement is essential.

Methods: Hypertension estimates in the National Longitudinal Study of Adolescent Health (Add Health), Wave IV (2008)-a nationally representative field study of 15,701 participants aged 24-32-was referenced against NHANES (2007-2008) participants of the same age. We examined discordances in hypertension, and estimated the accuracy and reliability of blood pressure in the Add Health study.

Origins of disparities in cardiovascular disease: birth weight, body mass index, and young adult systolic blood pressure in the national longitudinal study of adolescent health.

Purpose: We evaluated the contributions of birth weight and current body mass index (BMI) to racial/ethnic disparities in systolic blood pressure (SBP) in the United States.

Methods: Participants were 10,046 young adults (ages 24-32) in the National Longitudinal Study of Adolescent Health. SBP, BMI, and other contemporaneous factors were assessed at Wave IV (2007-2008); birth weight and other early life factors were reported at Wave I (1994-1995).

Childhood abuse and neglect and the risk of STDs in early adulthood.

Context: Given the threat posed by STDs in young adulthood, identifying early predictors of STD risk is a priority. Exposure to childhood maltreatment has been linked to sexual risk behaviors, but its association with STDs is unclear.

Methods: Associations between maltreatment by parents or other adult caregivers during childhood and adolescence and STD outcomes in young adulthood were examined using data on 8,922 respondents to Waves 1, 3 and 4 of the National Longitudinal Study of Adolescent Health.

Perceptions of neighborhood collective efficacy moderate the impact of maltreatment on aggression.

This study examined the moderating influence of positive neighborhood factors such as social cohesion and informal social control (collective efficacy), on the relationship between child maltreatment and aggressive behavior at age 12. Caregiver (N = 861) and youth (N = 823) dyads were interviewed when youth were aged 12 as part of a longitudinal study of child abuse and neglect (LONGSCAN). Caregivers and youth provided reports of youth externalizing behaviors while caregivers provided perceptions of collective efficacy.

Importance of early neglect for childhood aggression.

Objective: The goal was to examine the association between early childhood neglect (birth to age 2 years) and later childhood aggression at ages 4, 6, and 8 years, compared with aggression's associations with early childhood abuse and later abuse and neglect.

Methods: A prospective cohort of 1318 predominantly at-risk children, recruited from 4 US cities and 1 southern state, were monitored from birth to 8 years of age. Maltreatment was determined through review of local child protective services records.

Concordance between adolescent reports of childhood abuse and Child Protective Service determinations in an at-risk sample of young adolescents.

This study examines the concordance between adolescent reports of abuse and abuse determinations from Child Protective Service (CPS) agencies. It also compares the utility of adolescent reports of abuse, relative to CPS determinations in predicting adolescent psychological adjustment. The sample included 350 early adolescents, ages 12 to 13 years, who were initially identified prior to age 2 years as being at elevated risk of maltreatment.
