Despite growing interest in placental epigenetics, the combined impact of prenatal stress and socioeconomic status on placental methylation is still largely understudied. We conducted a study to examine the associations of prenatal stress and socioeconomic factors (household income, Hollingshead socioeconomic index) with placental methylation.…

High-risk sexual behaviors (HRSBs; e.g., having sex without protection against pregnancy or sexually transmitted infections) are a public health problem. HRSBs disproportionally impact college students and are associated with numerous negative outcomes, such as unwanted pregnancies. Alcohol use has been strongly linked to HRSBs in college…

This study examined the development of caregiver mind-mindedness--defined as the propensity to see one's child as an agent with an independent mind--across the first 1,000 days of life. At four timepoints (i.e., third trimester of pregnancy, 4, 14, and 24 months postpartum), 384 first-time mothers (M[subscript age] = 32.55, SD = 3.63 years) and…

We estimated risk factors associated with suspected neuropsychomotor developmental delay at age 2 years, in a birth cohort in the Brazilian Amazon. The Maternal and Child Health and Nutrition in Acre (MINA-Brasil) study is a population-based birth cohort involving children born between July 2015 and June 2016 in the municipality of Cruzeiro do…

Objective: Numerous studies have examined the effectiveness of graphic health warnings on different population segments, including male and female smokers, in an effort to reduce health disparities in Europe and the USA. However, research exploring the impact of gender-specific tobacco control interventions on Asian smokers is lacking. This study…

Although Ghana's comprehensive sexuality education (CSE) program has been lauded, no study has examined its association with the sexual health outcomes of Ghanaian youth. Using data collected from 2,982 in-school youth (male = 1,820 and female = 1,162) aged 15 to 17 years in three administrative regions of the country, we applied discrete-time…

A better understanding of the social influences, self-efficacy, and communication with parents, peers, and teachers associated with teenage pregnancy is required owing to the consequences of teenage pregnancy. This article aimed to determine the prevalence of teenage pregnancy and to understand the association between social influences,…

Background: The purpose of this study was to assess the protective influence of individual, family, and community assets from the initiation of sexual intercourse (ISI) for adolescents living in one-parent households compared with adolescents living in two-parent households. Methods: Five waves of data were collected annually over a 4-year period…

A systematic literature review was conducted to assess the utility of Positive Youth Development (PYD) concepts in promoting positive sexual health behaviors in young minority adolescents (n = 12 studies). Interventions reported significant associations between PYD-focused interventions and ever having sex, sexual partners in the last 30 days,…

Clinically meaningful behavior problems are thought to be present beginning in the early toddler years, yet few studies have investigated correlates of behavior problems assessed before age 2 years. The current study investigated the direct and interactive contributions of early infant and caregiver characteristics thought to play an important…

Maternal cortisol levels (at 15, 19, 25, 31 and 37 weeks' gestation) and fetal movement response to vibroacoustic stimulation (VAS; at 25, 31 and 37 weeks) were assessed in 190 mother-fetus pairs. Fetuses showed a response to the VAS at 25 weeks and there was evidence of increasing maturation in the response at 31 and 37 weeks. Early elevations in…

The study examined the relationship between young adolescents' sources of information on sex and precursors to sexual activity. Surveys were conducted with 3,940 Latino sixth grade students.

Data from 1,087 adolescent participants in three waves of the National Longitudinal Study of Adolescent Health were used to examine the effects of peer selection and socialization processes in adolescence on later reports of sexually transmitted infections (STI) and unintended pregnancies. Friends' attitudes and behavior were assessed with…

We contribute to research on the relationships between gender, work, and health by using longitudinal, theoretically driven models of mothers' diverse work pathways and adjusting for unequal selection into these pathways. Using the National Longitudinal Study of Youth-1979 (N = 2,540), we find full-time, continuous employment following a first…

Despite recent declines, Latinas bear a disproportionate burden of teen births. Understanding social, cultural, and demographic factors underlying pregnancy desire among Latino adolescents is needed to design effective teen pregnancy prevention interventions. A questionnaire was completed by 794 Latino youth including a "pregnancy wantedness…
