OBJECTIVE To determine the heritability of age at natural menopause from mother-daughter pairs. DESIGN Two-generation families were selected to study heritability of menopausal age. SETTING Subjects were drawn from a population-based study. PATIENT(S) One hundred sixty-four mother-daughter pairs with a natural menopausal age. INTERVENTION(S) None.(More)
OBJECTIVE To verify whether a population-based hypothesis (age at menarche and age at natural menopause have an inverse relationship) also applies at the level of the individual and to investigate what other factors predict age at natural menopause. DESIGN Prospective cohort study (the Doorlopend Onderzoek Morbiditeit/Mortaliteit [DOM] project). SETTING(More)
This meta-analysis of 161 published and unpublished manuscripts was conducted to determine whether the association between parenting and delinquency exists and what the magnitude of this linkage is. The strongest links were found for parental monitoring, psychological control, and negative aspects of support such as rejection and hostility, accounting for(More)
We investigated trajectories of adolescent delinquent development using data from the Pittsburgh Youth Study and examined the extent to which these different trajectories are differentially predicted by childhood parenting styles. Based on self-reported and official delinquency seriousness, covering ages 10-19, we identified five distinct delinquency(More)
The concurrent correlates and developmental antecedents of personality types were investigated in a sample of 305 14-19-year-old Dutch adolescents. Concurrent characteristics and developmental antecedents included adjustment and parental control. We also examined whether parental control interacted with personality type in exaggerating differences among the(More)
The present meta-analysis studies the relations of pubertal timing and status with sexual behavior and sexual risk behavior among youth aged 10.5-22.4 years. We included biological sex, age, and ethnicity as potential moderators. Four databases were searched for studies (published between 1980 and 2012) on the relation between pubertal timing or status and(More)
Using structural equation modeling, this study investigates father-child, mother-child, and father-mother transmissions on "work-as-duty" and "hedonism" across a 5-year period when children traverse late adolescence and emerging adulthood (N = 402 families). We found bidirectional father-child and child-to-mother transmissions on work-as-duty and(More)
OBJECTIVE During the central nervous system (CNS) growth spurt, rapid accretion of long chain polyunsaturated fatty acids (LCPUFA) takes place. This particularly concerns docosahexaenoic acid (DHA, 22:6n-3) and arachidonic acid (AA, 20:4n-6), which are thought to play important roles in CNS development and function. The aim of this study was to investigate(More)
Males typically surpass females in spatial performance, an outcome that may be linked to testosterone and estrogen. The authors (a) review physiological mechanisms, developmental periods, and past empirical work relevant to sex steroids' effects on human spatial performance and (b) report an experimental study of the role of actively circulating sex(More)
Despite evident heightened adolescent risk-taking in real-life situations, not all experimental studies demonstrate that adolescents take more risks than children and adults on risky decision-making tasks. In the current 4 independent meta-analyses, neurodevelopmental imbalance models and fuzzy trace theory were used as conceptual frameworks to examine(More)
