Prenatal exposure to tobacco and cannabis, early cannabis initiation, and daily dual use of combustible cigarettes and cannabis during young adulthood.

Introduction: Daily combustible cigarette use is common among cannabis users, and dual use of cigarettes and cannabis is associated with detrimental outcomes. This study addresses gaps in the literature by examining data from the prenatal and adolescent phases of a prospective, longitudinal study to predict adult daily dual use.

Methods: Young adult offspring (M age = 22.

The Role of Cognitive Stimulation in the Home and Maternal Responses to Low Grades in Low-Income African American Adolescents' Academic Achievement.

Parental involvement in education has generally been shown to foster adolescent academic achievement, yet little is known about whether two important forms of parental involvement-how parents respond to academic underachievement and how parents provide cognitive stimulation in the home-are related to academic achievement for African American adolescents. This study uses two waves of data to evaluate whether these forms of parental involvement are related to future academic achievement for low-income African American adolescents and whether there are gender differences in these associations. African American mothers and adolescents (N = 226; 48% girls) were interviewed when adolescents were ages 14 and 16.

Prenatal alcohol exposure and offspring alcohol use and misuse at 22 years of age: A prospective longitudinal study.

Studies have shown that prenatal alcohol exposure (PAE) is related to drinking problems during adulthood, but the level of prenatal exposure associated with young adults' quantity and frequency of alcohol use and drinking problems has not yet been established. The relation between PAE and offspring levels of alcohol use and alcohol abuse/dependency was examined in 608 22-year-olds. Mothers were recruited in early pregnancy and maternal alcohol use data were collected for each trimester of pregnancy.

Trajectories of pre- and postnatal co-use of cannabis and tobacco predict co-use and drug use disorders in adult offspring.

Co-use of cannabis and tobacco is increasingly common among women and is associated with tobacco and cannabis dependence and poorer cessation outcomes. However, no study has examined maternal patterns of co-use over time, or the impact of maternal co-use on co-use and drug problems in adult offspring. Pregnant women (M age = 23, range = 18-42; 52% African American, 48% White) were asked about substance use during each trimester of pregnancy, and at 8 and 18 months, 3, 6, 10, 14, 16, and 22 years postpartum.

Prenatal exposures to tobacco and cannabis: Associations with adult electronic cigarette use.

Introduction: Prenatal exposures to tobacco and cannabis are associated with combustible cigarette use. This study evaluated pathways from these prenatal exposures to adult electronic cigarette use. We tested whether there were indirect effects of these prenatal exposures via childhood behavior dysregulation, early tobacco use, and adolescent tobacco dependence.

Maternal Age and Trajectories of Risky Alcohol Use: A Prospective Study.

Background: No prospective study of maternal alcohol use has focused on age at transition to motherhood as a predictor of trajectories of risky drinking. The goal of this study was to examine the impact of maternal age at first birth on trajectories of alcohol use beyond recommended levels over a 17-year span.

Methods: Pregnant women (N = 456) were recruited at an urban prenatal clinic.

Prenatal tobacco exposure, maternal postnatal nicotine dependence and adolescent risk for nicotine dependence: Birth cohort study.

Aims: The goals of this study are to determine if there is (a) a threshold effect for prenatal tobacco exposure (PTE) on adolescent risk for nicotine dependence, and (b) an additive effect of PTE and maternal postnatal nicotine dependence on adolescent risk for nicotine dependence.

Methods: Pregnant women were recruited in their 4th or 5th gestational month and asked about cigarette use during the first trimester. Mothers reported on third trimester cigarette use at delivery.

Maternal trajectories of cigarette use as a function of maternal age and race.

Background: Patterns of smoking vary as a function of age and race. The goals of this study were to identify trajectories of maternal cigarette use over a 17-year span, and to determine if maternal age at first birth and race were associated with smoking trajectories.

Methods: Pregnant women (N=690) were recruited at an urban prenatal clinic.

Gestational Alcohol Exposure and Other Factors Associated With Continued Teenage Drinking.

Purpose A longitudinal cohort of adolescents who initiated drinking before age 15 were studied to determine which factors distinguished between early initiators who continued to drink (persisters) from those who stopped drinking (desisters). There were 308 early initiators in the total sample (n = 917); 247 were persisters, and 61 were desisters. Method A stepwise discriminant analysis identified differences between the two groups.

Adverse Environmental Exposures During Gestation and Childhood: Predictors of Adolescent Drinking.

Adverse conditions, including exposures to drugs and other environmental influences during early development, may affect behaviors later in life. This study examined the role of environmental influences from the gestation and childhood on adolescent drinking behavior. 917 mother/offspring dyads were followed prospectively from pregnancy to a 16-year follow-up assessment.

Abusive Experiences and Young Women's Sexual Health Outcomes: Is Condom Negotiation Self-Efficacy a Mediator?

Context: Intimate partner violence and reproductive coercion are associated with unintended pregnancies and STDs. Greater condom negotiation self-efficacy among young women may mediate these associations.

Methods: A sample of 841 female adolescents (aged 16-19) and 1,387 young adult women (aged 20-24) recruited from 24 family planning clinics in western Pennsylvania in 2011-2012 reported on intimate partner violence, reproductive coercion, condom negotiation self-efficacy and sexual health outcomes at baseline and four- and 12-month follow-ups.

Prenatal alcohol and other early childhood adverse exposures: Direct and indirect pathways to adolescent drinking.

We examined direct and indirect pathways between adverse environmental exposures during gestation and childhood and drinking in mid-adolescence. Mothers and their offspring (n=917 mother/child dyads) were followed prospectively from second trimester to a 16-year follow-up assessment. Interim assessments occurred at delivery, 6, 10, and 14years.

Family Resources as Protective Factors for Low-Income Youth Exposed to Community Violence.

Exposure to community violence is a risk factor for internalizing and externalizing problems; however, resources within the family can decrease the likelihood that adolescents will experience internalizing and externalizing problems as a result of such exposure. This study investigates the potential moderating effects of kinship support (i.e.

Maternal age and trajectories of cannabis use.

Background: Becoming a mother is a developmental transition that has been linked to desistance from substance use. However, timing of motherhood may be a key determinant of cannabis use in women, based on preliminary evidence from teenage mothers. The goal of this study was to identify trajectories of maternal cannabis use, and to determine if maternal age was associated with different trajectories of use.

Socioemotional Adjustment as a Mediator of the Association between Exposure to Community Violence and Academic Performance in Low-Income Adolescents.

Objective: This study examines whether exposure to community violence is indirectly related to academic performance through anxious/depressed symptoms and delinquent behaviors.

Methods: Three hundred eighteen mothers and adolescents who participated in a longitudinal investigation were interviewed when adolescents were age 10, 14, and 16.

Results: Community violence exposure at age 14 was significantly related to anxious/depressed symptoms and delinquent behaviors.

Maternal drinking and risky sexual behavior in offspring.

Teenage mothers are more likely to use drugs, and their children are more likely to use substances and become pregnant during adolescence. Teenage mothers' substance use may play a role in the intergenerational risk for adolescent pregnancy. Pregnant adolescents (12-18 years) were seen during pregnancy and postnatal years 6, 10, 14, and 16 (n = 332).

Maternal patterns of marijuana use and early sexual behavior in offspring of teenage mothers.

Teenage mothers use marijuana more frequently than older mothers, and marijuana use may predict HIV risk behavior in offspring. Our goals were to (1) describe trajectories of marijuana use in teenage mothers and (2) determine if these trajectories were associated with early sexual behavior in their offspring. Pregnant adolescents (12-18 years) were recruited at a prenatal clinic and interviewed during pregnancy, at delivery, and during follow-up visits when offspring were 6, 10, 14 and 16 years old.

Economic hardship and adolescent problem drinking: family processes as mediating influences.

Alcohol is the most commonly used substance among adolescents in the United States, and adolescent drinking is associated with various health risk behaviors. Given the prevalence and consequences of adolescent drinking, understanding family factors that contribute to adolescent drinking is an important area for research. This study used three waves of data to evaluate a family stress model in which economic hardship is indirectly related to adolescent problem drinking through maternal psychological distress, parenting behaviors, and adolescent externalizing behaviors.

The dysregulation profile predicts cannabis use in the offspring of teenage mothers.

Background. Offspring of teenage mothers are at greater risk of early drug use. Research has identified a child behavior checklist (CBCL) profile for children with high levels of comorbid behavior problems, the dysregulation profile (DP), as another risk factor for drug use.

Prenatal cigarette smoking: Long-term effects on young adult behavior problems and smoking behavior.

We examined the long-term effects of prenatal cigarette smoke exposure (PCSE) on the behavior problems and smoking behavior of 22-year-old offspring. The mothers of these offspring were interviewed about their tobacco and other drug use during pregnancy at the fourth and seventh gestational months, and at delivery. Data on the offspring are from interviews at age 22 (n=608).

Prenatal cigarette smoke exposure and early initiation of multiple substance use.

Introduction: Earlier studies have shown a relation between prenatal cigarette smoke exposure (PCSE) and offspring initiation of tobacco use. No prior study has examined the association between PCSE and early initiation of multiple substances (EIMS) including marijuana and alcohol in addition to tobacco. We investigated the association between PCSE and multiple substance use during adolescence.

Long-term effects of prenatal cigarette smoke exposure on behavior dysregulation among 14-year-old offspring of teenage mothers.

In this prospective study, we examined the long-term effects of prenatal cigarette smoke exposure (PCSE) on behavioral dysregulation (BD) in the offspring of adolescent mothers. The adolescent mothers (mean age = 16; range = 12-18; 70% African American) were interviewed about their tobacco use during pregnancy. Offspring were followed to age 14 years (n = 318).

Pubertal timing and early sexual intercourse in the offspring of teenage mothers.

Early puberty is associated with stressful family environments, early sexual intercourse, and teenage pregnancy. We examined pubertal timing and sexual debut among the 14-year-old offspring of teenage mothers. Mothers (71% Black, 29% White) were recruited as pregnant teenagers (12-18 years old).
