Parental imprisonment, delinquent behavior, and BMI gain in a U.S. nationally representative cohort study of adolescents and adults ages 12-32.

Children who experience parental imprisonment report greater mental and physical health adversities in adolescence and adulthood relative to comparable individuals whose parents did not serve time in prison. Research has linked BMI gain with parental imprisonment among females, but other studies have shown null or negative associations between parental imprisonment and weight increases for their offspring. Using longitudinal data from the National Longitudinal Study of Adolescent to Adult Health, this study attempts to resolve these differential findings by examining the interrelationship between delinquent behavior and BMI associated with parental imprisonment as individuals progress from adolescence into adulthood (ages 12-32). We show that higher delinquency levels are associated with lower BMI among men and women. With the transition from adolescence to adulthood, parental imprisonment is linked with increased BMI gain and obesity among females who are not delinquent. These findings highlight the need to consider how the decline in delinquent behavior and increasing health disparities between adolescence and adulthood may intersect as individuals experiencing parental imprisonment transition from adolescence to adulthood.

Parental imprisonment as a risk factor for cardiovascular and metabolic disease in adolescent and adult offspring: A prospective Australian birth cohort study.

Objectives: Parental imprisonment is linked with child health in later life. The present study provides the first prospective cohort analysis and non-U.S. based study examining parental imprisonment and cardiometabolic risk factors in adolescence and adulthood. Methods: The study followed 7,223 children born from live, singleton births from 1981 to 1984 in Brisbane, Australia. Data on parental imprisonment was collected at mother interview when the children were ages 5 and 14. Our sample analyzes offspring with biometric data collected by health professionals, including 3,794 at age 14, 2,136 at age 21, and 1,712 at age 30. Analyses used multivariate linear and logistic regression, and time-varying growth curve models. Results: Among female respondents, parental imprisonment at ages ≤5 was associated with higher body-mass index (BMI) at ages 14, 21, and 30; higher systolic blood pressure (SBP) and diastolic blood pressure (DBP) at age 30; and increased sedentary hours, larger waist circumference, and odds of a high-risk waist circumference at age 30. Parental imprisonment when the child was aged ≤14 was associated with increased BMI and SBP at age 30 for females. In growth-curve models, parental imprisonment when the child was aged ≤5 and ≤ 14 among females was linked with increased BMI; parental imprisonment when the child was aged ≤5 was associated with increased SBP and DBP. No significant associations were observed for males. Conclusions: Using prospective cohort data, our results support research showing that parental imprisonment, particularly in early childhood, is associated with increased BMI, blood pressure, sedentary hours, and waist circumference in females in early adulthood. These findings implicate parental imprisonment as a risk factor for cardiometabolic health issues in later life among females.

Assessing the relationship between parental imprisonment in childhood and risk of sexually transmitted infections: a cohort study of US adults in early adulthood.

OBJECTIVES: One in six young adults in the USA experiences parental imprisonment in childhood. Prior studies have associated parental imprisonment with risk of sexually transmitted infection (STI); however, potential data and methodological issues may have limited the reliability and accuracy of prior findings. Examining cumulative and longitudinal risk, we address several methodological limitations of prior studies and also examine comparative risk by respondent sex and ethnicity. We assess these associations using a range of control variables. DESIGN: A national cohort study from the National Longitudinal Study of Adolescent to Adult Health using (1) a cross-sectional sample of adults at ages 24-32 years and (2) a longitudinal sample between ages 18 and 32 years. Both analyses estimate ORs for STI associated with parental imprisonment and examine variation by parent/child gender and respondent ethnicity. SETTING: In-home interviews in the USA at wave 1 (1994-1995), wave 3 (2001-2003) and wave 4 (2007-2009). PARTICIPANTS: 15 684 respondents completing interviews at wave 1 (ages 12-18 years) and wave 4 (ages 26-32 years), including 8556 women, 3437 black and 2397 respondents reporting parental imprisonment. RESULTS: Father-only imprisonment is associated with 1.22 higher odds (95% CI: 1.09 to 1.37) of lifetime STI and 1.19 higher odds (95% CI: 1.01 to 1.41) of STI in the past 12 months between ages 18 and 32 years, adjusting for familial, neighbourhood, individual and sexual risk factors. Maternal imprisonment is not associated with higher risk of lifetime STI after adjusting for confounders (95% CI: 0.90 to 1.61). Examining predicted probabilities of STI, our findings show additive risks for women, black people and parental imprisonment. CONCLUSION: Adjusting for confounders, only paternal imprisonment is associated with slightly elevated risk of annual and lifetime risk of STI. Additive effects show that parental imprisonment modestly increases ethnic and female risk for STI.

Prospective Relations Between Prenatal Maternal Cortisol and Child Health Outcomes.

OBJECTIVE: The aim of the study was to investigate prospective, longitudinal associations between maternal prenatal cortisol response to an interpersonal stressor and child health for the subsequent 3 years. METHODS: One hundred twenty-three women expecting their first child provided salivary cortisol samples between 12 and 32 weeks of gestation (M (SD) = 22.4 (4.9) weeks) before and after a videotaped couple conflict discussion with their partner. Mothers reported on overall child health and several indicators of child illness (sick doctor visits, fevers, ear, and respiratory infections) when children were 6 months (n = 114), 1 (n = 116), and 3 (n = 105) years old. Associations between maternal prenatal cortisol reactivity and recovery and later child health at each of the three time points were analyzed using longitudinal regression models. RESULTS: Greater cortisol reactivity in response to the couple conflict discussion was associated with maternal self-report of better overall child health (p = .016, 95% CI = 0.06-1.30, Cohen's f = 0.045) across the study period. Greater cortisol reactivity was also associated with lower incidence rate ratios for maternal reports of sick doctor visits (incidence rate ratio 95% CI = 0.25-0.83, p = .006), fevers (95% CI = 0.25-0.73, p = .002), ear infections (95% CI = 0.25-0.58, p < .001), and respiratory infections (95% CI = 0.08-1.11, p = .073). Cortisol recovery was unrelated to study outcomes (all p's > 0.05). Maternal prenatal depressive symptoms moderated the association between cortisol reactivity and overall child health (p = .034, 95% CI = 0.07-1.87 for interaction term) but no other health outcomes (p's > 0.05). Among women with lower depressive symptoms, cortisol reactivity was not associated with overall child health; among women with higher levels of depressive symptoms, greater cortisol reactivity was associated with better overall child health. CONCLUSIONS: This study provides longitudinal evidence that greater maternal cortisol reactivity to a salient interpersonal stressor during pregnancy is associated with fewer child health problems and better maternal report of overall child health during infancy and into early childhood.

Family and Child Outcomes 2 Years After a Transition to Parenthood Intervention.

OBJECTIVE: To examine the impact from Family Foundations, a transition-to-parenting intervention, on parent and child outcomes 2 years after birth. BACKGROUND: Couples transitioning to parenthood face many stressors and challenges that are not typically addressed through commonly available childbirth preparatory classes. The Family Foundations program was designed for couples expecting their first child and addresses family stressors related to coparenting, parenting, and mental health. METHOD: The recruited sample of 399 couples expecting their first child were randomly assigned to intervention or control conditions. Data were obtained through home observation and parent surveys before and after intervention. RESULTS: Intent-to-treat analyses indicated effects on several targeted domains including coparenting, parenting, and relationship quality, as well as on child sleep habits and internalizing behavior problems at 2 years of age. Effects for several outcomes were larger for those couples at greater risk based on pretest observed negative dyadic communication styles. CONCLUSION: Longer term impact found here on parent and child outcomes provides new evidence of the effectiveness of this program for first-time parents. IMPLICATIONS: Programs directed toward broader issues related to aspects of coparenting, parenting, and mental health have the potential to have longer term positive impact on the couples and the developing child.

Trauma exposure and aggression toward partners and children: Contextual influences of fear and anger.

Trauma exposure is a consistent correlate of intimate partner aggression (IPA) and parent-to-child aggression (PCA) perpetration, and difficulties with emotions (particularly fear and anger) are hypothesized to underlie these relations. However, the absence of knowledge of the immediate, contextual influence of emotions on aggression renders existing conclusions tenuous. This study illustrates a new method for studying contextual influences on aggressive behavior. Quarterly for 1 year, 94 men and 109 women with children age 2.5 years at study commencement were interviewed to measure the sequence of behaviors during aggressive incidents as well as the intensity of their emotions immediately prior to initiation of aggression. Within aggressive incidents, the number of acts of men's PCA was predicted by men's greater fear, anger, and trauma exposure, and the positive association between men's trauma exposure and PCA perpetration was especially strong under conditions of high fear and anger. In contrast, men's IPA was predicted by greater fear and anger, but not trauma exposure. Men with low trauma exposure engaged in more IPA under conditions of high fear; among men with high trauma exposure, fear inhibited their IPA persistence. Trauma exposure and fear interacted in the same manner to predict women's IPA, but many other findings among men did not generalize to women's aggression. This study illuminates the utility of simultaneously examining aggression across genders and family dyads, and serves as a foundation for refining theories of trauma and family aggression to account for emotion as a factor that can both motivate and inhibit aggression.

Couple-Focused Prevention at the Transition to Parenthood, a Randomized Trial: Effects on Coparenting, Parenting, Family Violence, and Parent and Child Adjustment.

The transition to parenthood is a stressful period for most parents as individuals and as couples, with variability in parent mental health and couple relationship functioning linked to children's long-term emotional, mental health, and academic outcomes. Few couple-focused prevention programs targeting this period have been shown to be effective. The purpose of this study was to test the short-term efficacy of a brief, universal, transition-to-parenthood intervention (Family Foundations) and report the results of this randomized trial at 10 months postpartum. This was a randomized controlled trial; 399 couples expecting their first child were randomly assigned to intervention or control conditions after pretest. Intervention couples received a manualized nine-session (five prenatal and four postnatal classes) psychoeducational program delivered in small groups. Intent-to-treat analyses indicated that intervention couples demonstrated better posttest levels than control couples on more than two thirds of measures of coparenting, parent mental health, parenting, child adjustment, and family violence. Program effects on family violence were particularly large. Of eight outcome variables that did not demonstrate main effects, seven showed moderated intervention impact; such that, intervention couples at higher levels of risk during pregnancy showed better outcomes than control couples at similar levels of risk. These findings replicate a prior smaller study of Family Foundations, indicating that the Family Foundations approach to supporting couples making the transition to parenthood can have broad impact for parents, family relationships, and children's adjustment. Program effects are consistent and benefit all families, with particularly notable effects for families at elevated prenatal risk.

The association between the MAOA 2R genotype and delinquency over time among men: the interactive role of parental closeness and parental incarceration.

Using a panel of 6,001 males from the National Longitudinal Study of Adolescent and Adult Health, we examine potential moderation by paternal incarceration and parent-child closeness altering the relationship between the rare 2R MAOA genotype and delinquency. By jointly examining moderation patterns for both the mother and father with the transmission of the MAOA genotype from mother to son, we are able to make inferences about the specific genetic model that best explains these outcomes. In line with prior research, we find a direct relationship between the MAOA 2R genotype and delinquency, independent of parental incarceration and closeness. Examining moderation patterns, we find that delinquency risk for the 2R allele is buffered for males close to their biological or social father, but not their biological mother. We conclude that the 2R delinquency association is not due to passive gene-environment correlation but is best characterized as a social control gene-environment interaction.

Preventive Effects on Birth Outcomes: Buffering Impact of Maternal Stress, Depression, and Anxiety.

OBJECTIVE: Although maternal stress, anxiety, and depression have been linked to negative birth outcomes, few studies have investigated preventive interventions targeting maternal mental health as a means of reducing such problems. This randomized controlled study examines whether Family Foundations (FF)-a transition to parenthood program for couples focused on promoting coparenting quality, with previously documented impact on maternal stress, depression, and anxiety-can buffer the negative effects of maternal mental health problems. METHODS: To assess the effects of FF, we used a randomized block design with a sample of 259 expectant mothers assigned to FF or a control condition and analyzed using propensity score models. We examine two-way interactions of condition (intervention vs. control) with maternal mental health problems (financial stress, depression, and anxiety) on birth outcomes (birth weight, days in hospital for mothers and infants). For birth weight, we assess whether intervention effects depend on length of gestation by including a third interaction term. RESULTS: FF buffered (p < 0.05) the negative impact of maternal mental health problems on birth weight and both mother and infant length of post-partum hospital stay. For birth weight, assignment to FF was associated with higher birth weight for infants born before term. CONCLUSIONS: These results demonstrate that a psycho-educational program for couples focused on enhancing mutual coparental support, with preventive effects on maternal mental health, can reduce incidence of birth problems among women at elevated risk. Such improvements in birth outcomes could translate into substantial reductions in public and personal healthcare costs. Future work should assess mediating mechanisms of intervention impact and cost-benefit ratio of the intervention. CLINICAL TRIALS REGISTRATION: The Family Foundations follow-up intervention study is currently registered with www.clinicaltrials.gov . The study identifier is NCT01907412.

Effects of a psychosocial couple-based prevention program on adverse birth outcomes.

Although maternal stress and depression have been linked to adverse birth outcomes (ABOs), few studies have investigated preventive interventions targeting maternal mental health as a means of reducing ABOs. This randomized controlled study examines the impact of Family Foundations (FF)-a transition to parenthood program for couples focused on promoting coparenting quality, with previously documented impact on maternal stress and depression-on ABOs. We also examine whether intervention buffers birth outcomes from the negative effect of elevated salivary cortisol levels. We use intent-to-treat analyses to assess the main effects of the FF intervention on ABOs (prematurity, birth weight, pregnancy complications, Cesarean section, and days in hospital for mothers and infants) among 148 expectant mothers. We also test the interaction of cortisol with intervention condition status in predicting ABOs. FF participation was associated with reduced risk of C-section (OR .357, p < 0.05, 95 % CI 0.149, 0.862), but did not have main effects on other ABOs. FF significantly buffered (p < 0.05) the negative impact of maternal cortisol on birth weight, gestational age, and days in hospital for infants; that is, among women with relatively higher levels of prenatal cortisol, the intervention reduced ABOs. These results demonstrate that a psycho-educational program for couples reduces incidence of ABOs among higher risk women. Future work should test whether reduced maternal stress and depression mediate these intervention effects.

Long-term follow-up of a randomized trial of family foundations: effects on children's emotional, behavioral, and school adjustment.

This study examines long-term effects of a transition to parenthood program, Family Foundations, designed to enhance child outcomes through a strategic focus on supporting the coparenting relationship. Roughly 5 to 7 years after baseline (pregnancy), parent and teacher reports of internalizing and externalizing problems and school adjustment were collected by mail for 98 children born to couples enrolled in the randomized trial. Teachers reported significantly lower levels of internalizing problems among children in the intervention group compared with children in the control group and, consistent with prior findings at age 3, lower levels of externalizing problems for boys in the intervention group. Baseline level of observed couple negative communication moderated intervention effects for parent and teacher report of child adjustment and teacher report of school adjustment and adaptation. Effect sizes ranged from 0.40 to 0.98. Results indicate that relatively brief preventive programs for couples at the transition to parenthood have the capacity to promote long-term positive benefits for children's adjustment. Although we attended to missing data issues in several ways, high levels of attrition in this long-term follow-up study is a cause for caution.

Genes in the dopaminergic system and delinquent behaviors across the life course: the role of social controls and risks.

This paper examines the interaction between social control and social risk mechanisms and genes within the dopaminergic system (DAT1 and DRD2) as related to serious and violent forms of delinquent behavior among adolescents and young adults. We use nine waves of data from the National Youth Survey Family Study to examine the relevance of protective or risky social factors at four social levels including school, neighborhood, friends, and family within the gene-environment interaction framework. We extend previous work in this area by providing a testable typology of gene-environment interactions derived from current theories in this area. We find consistent evidence that the associations between putatively risky genotypes and delinquent behavior are suppressed within protective social environments. We also provide some evidence that supports the differential susceptibility hypothesis for these outcomes. Our findings largely confirm the conclusions of previous work and continue to highlight the critical role of the social environment within candidate gene studies of complex behaviors.

Measures of sexual minority status and suicide risk among young adults in the United States.

Multiple measures of sexual minority status are necessary to accurately describe the diversity of attractions, identities, and behaviors in sexual minority populations. We investigated whether four measures of sexual minority status (sexual minority attraction, sexual minority identity, sexual minority lifetime behavior, and sexual minority recent 12-month behavior) were associated with suicidal thoughts and suicide attempts among young adults ages 24 to 34 in the United States. We analyzed data from Wave IV (2007-2008) of the National Longitudinal Study of Adolescent Health. We employed logistic regression models in the analysis. Multiple sexual minority status measures had significant associations with increased suicidal thoughts among women and men. Multiple sexual minority status measures had significant associations with increased suicide attempts among women, but not among men. Diverse sexual minority populations are at increased risk for suicidal thoughts and suicide attempts. Multiple measures of sexual minority status should be utilized in future studies of sexual minority status and suicide risk. Suicide prevention programs should ensure intervention is available across diverse sexual minority populations.

Father's Incarceration and Youth Delinquency and Depression: Examining Differences by Race and Ethnicity.

This paper examines associations between biological father's incarceration and internalizing and externalizing outcomes of depression and serious delinquency, across White, Black, and Hispanic subsamples of youth in the National Longitudinal Study of Adolescent Health. Among respondents whose father was first incarcerated during childhood or adolescence, father's incarceration is found to be associated with increased depression and delinquency. On the whole, results indicate that associations between father's incarceration and depression and delinquency do not vary by race and ethnicity or gender. One exception is among Hispanic respondents, for whom having a biological father incarcerated is associated with an even higher propensity of delinquency than among White and Black respondents with incarcerated fathers.

Gene-environment interactions related to body mass: School policies and social context as environmental moderators.

This paper highlights the role of institutional resources and policies, whose origins lie in political processes, in shaping the genetic etiology of body mass among a national sample of adolescents. Using data from Waves I and II of the National Longitudinal Study of Adolescent Health, we decompose the variance of body mass into environmental and genetic components. We then examine the extent to which the genetic influences on body mass are different across the 134 schools in the study. Taking advantage of school differences in both health-related policies and social norms regarding body size, we examine how institutional resources and policies alter the relative impact of genetic influences on body mass. For the entire sample, we estimate a heritability of .82, with the remaining .18 due to unique environmental factors. However, we also show variation about this estimate and provide evidence suggesting that social norms and institutional policies often mask genetic vulnerabilities to increased weight. Empirically, we demonstrate that more-restrictive school policies and policies designed to curb weight gain are also associated with decreases the proportion of variance in body mass that is due to additive genetic influences.

Parental incarceration and gender-based risks for increased body mass index: evidence from the National Longitudinal Study of Adolescent Health in the United States.

Although recent studies suggest that 13% of young adults, including at least one-fourth of African Americans, experience parental incarceration, little research has examined links between parental incarceration and physical health. Using data from the National Longitudinal Study of Adolescent Health (1994-2008) and gender-based theories of stress, the authors examined whether parental incarceration is associated with increased body mass index among women but not men. Panel analysis spanning adolescence and adulthood, controlling for stressful life events, internalizing behaviors, and a range of individual, familial, and neighborhood characteristics, reveals that body mass index for women who have experienced parental incarceration is 0.49 units (P < 0.004) higher than that for women whose parents have never been incarcerated. This association is not evident among men. Similarly, in change score models between waves II and IV, women experiencing parental incarceration have a 0.92-unit increase in body mass index (P < 0.026) relative to women who did not have a parent undergo incarceration. In supplemental analysis examining if gender differences in incarceration stress response (externalizing vs. internalizing) explain these findings, the authors found that obesity status moderates the relation between depression and parental incarceration. Results suggest a stress internalization process that, for the first time, links parental incarceration with obesity among women.

Paternal incarceration and trajectories of marijuana and other illegal drug use from adolescence into young adulthood: evidence from longitudinal panels of males and females in the United States.

AIMS: One-eighth of young adults in the United States report that their biological father has ever been incarcerated (FEI). This study is the first to examine associations between FEI and trajectories of substance use during the transition from adolescence into young adulthood for the US population. DESIGN: Using multi-level modeling techniques, trajectories of marijuana and other illegal drug use are examined, with FEI as the primary independent variable. SETTING: Data are from the first three waves of the National Longitudinal Study of Adolescent Health, a nationally representative sample of US adolescents beginning in 1995. PARTICIPANTS: Panels of 7157 males and 7997 females followed from adolescence (7th-12th grades) into early adulthood (ages 18-27 years). MEASUREMENTS: Dependent variables included an ordinal measure of marijuana frequency of use in last thirty days, and a dichotomous measure for whether respondent had any use in the last thirty days of illegal drugs such crystal meth, cocaine, heroin, hallucinogens, PCP, LSD, speed, and ecstasy. FINDINGS: Among males and females, respectively, FEI is associated with an increased frequency of marijuana use, and increased odds of any other illegal drug use. Interactions between FEI and age further reveal that FEI is associated with an accentuated trajectory (i.e. a steeper slope) of marijuana use, and an elevated risk (i.e. higher mean level) of other illegal drug use. CONCLUSIONS: Analysis provides some of the first evidence that paternal incarceration is significantly associated with drug use among U.S. males and females, even after controlling for a number of family background, parental, and individual characteristics.

The VNTR 2 repeat in MAOA and delinquent behavior in adolescence and young adulthood: associations and MAOA promoter activity.

Genetic studies of delinquent and criminal behavior are rare in spite of the wide recognition that individuals may differ in their propensity for delinquency and criminality. Using 2524 participants in Add Health in the United States, the present study demonstrates a link between the rare 2 repeat of the 30-bp VNTR in the MAOA gene and much higher levels of self-reported serious and violent delinquency. The evidence is based on a statistical association analysis and a functional analysis of MAOA promoter activity using two human brain-derived cell lines: neuroblastoma SH-SY5Y and human glioblastoma 1242-MG. The association analysis shows that men with a 2R report a level of serious delinquency and violent delinquency in adolescence and young adulthood that were about twice (CI: (0.21, 3.24), P=0.025; and CI: (0.37, 2.5), P=0.008 for serious and violent delinquency, respectively) as high as those for participants with the other variants. The results for women are similar, but weaker. In the functional analysis, the 2 repeat exhibits much lower levels of promoter activity than the 3 or 4 repeat.

Contributions of the DAT1 and DRD2 genes to serious and violent delinquency among adolescents and young adults.

As far as we know, this is the first national study that reports compelling evidence for the main effects of genetic variants on serious and violent delinquency among adolescents and young adults. This study investigated the association between the self-reported serious and violent delinquency and the TaqI polymorphism in the DRD2 gene and the 40-bp VNTR in the DAT1 gene. The study was based on a cohort of more than 2,500 adolescents and young adults in the National Longitudinal Study of Adolescent Health in the United States. The trajectories of serious delinquency for the DAT1*10R/10R and DAT1*10R/9R genotypes are about twice as high as that for the DAT1*9R/9R genotype (LR test, P = 0.018, 2 df). For DRD2, the trajectory of serious delinquency for the heterozygotes (A1/A2) is about 20% higher than the A2/A2 genotype and about twice as high as the A1/A1 genotype, a phenomenon sometimes described as heterosis (LR test, P = 0.005, 2 df). The findings on violent delinquency closely resemble those on serious delinquency. The trajectories of violent delinquency for the DAT1*10R/9R and DAT1*10R/10R genotype are again about twice as high as that for DAT1*9R/9R (LR test, P = 0.021, 2 df). The two homozygotes of DRD2*A1/A1 and DRD2*A2/A2 scored lower (LR test, P = 0.0016, 2 df) than the heterozygotes. The findings in the models that consider DAT1 and DRD2 jointly (serious delinquency P = 0.0016, 4 df; violent delinquency P = 0.0006, 4 df) are essentially the same as those in the single-gene models, suggesting the absence of a significant correlation between the two genetic variants. These results only apply to males. Neither variant is associated with delinquency among females.
