Fatherhood has traditionally been viewed as part of a “package deal,” where a father’s relationship with his child is contingent upon his relationship with the mother. We evaluate the accuracy of this hypothesis in light of the high rates of multiple-partnered fertility among unmarried parents using the Fragile Families and Child Wellbeing Study, a recent longitudinal survey of nonmarital birth...

Unlike the deoxyribonucleic acid (DNA)-deficient minicells produced by F(-) parents, minicells produced by plasmid-containing strains contain significant amounts of plasmid DNA. We examined the ability of plasmid-containing minicells to synthesize ribonucleic acid (RNA) and protein. In vivo, minicells produced by F(-) parents are unable to incorporate radioactive precursors into acid-insoluble ...

PURPOSE The aim of this study was to evaluate the association of three single nucleotide polymorphisms (SNPs, rs11712066 and rs573872 near MBNL1, rs29784 near NKX2-5) with infantile hypertrophic pyloric stenosis (IHPS) in Chinese Han population. METHODS A total of 47 family trios consisting of infants with IHPS and their healthy biological parents were recruited for this study. Genotypes were...

The Minnesota Twin Family Study is a longitudinal study of 11-year-old and 17-year-old twins and their parents designed to examine factors related to the etiology of substance abuse and related problems. At study intake, the twins and their parents participate in a day-long assessment in our laboratory that includes measures of endophenotypes (e.g., event-related potentials, EEG, autonomic nerv...

Little research has examined the transition to parenthood among couples who adopt through the child welfare system. The current qualitative study of 84 individuals within 42 couples (17 lesbian, 13 gay, and 12 heterosexual), who were placed with a child via foster care three months earlier, examined perceived changes in their intimate relationship. Findings indicated that, like heterosexual bio...

Although an extensive literature has shown that family structure is linked with child well-being, less well understood is how the dynamics within families affect children, in particular the extent to which positive mother-father relationship quality is linked with children's outcomes. In this study the authors used data from the Fragile Families and Child Wellbeing Study (N = 773) to examine ho...

Do adults’ perceptions of their mothers’ and fathers’ parenting practices in childhood vary by their mothers’ employment status? Among adults in the Survey of Midlife Development in United States who lived with 2 biological parents until the age of 16 years (N 1⁄4 2,246), those who had employed mothers during most or all of their childhood reported less support and less discipline from both par...

Many studies have explored the links between family structure, parental religiosity, and youth religiosity, but results across studies have been inconsistent and have largely ignored new diverse family forms. Using data on 2,320 youth and their parents from the National Study of Youth and Religion, this study focused on whether and why religious transmission from parents to youth varies among d...

BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) predisposes to drug abuse (DA) and twin studies suggest shared genetic effects. We here seek to determine, using adoption and adoption-like samples, the magnitude of the cross-generational transmission from DA in parents to ADHD in their children and clarify the degree to which this arises from genetic v. rearing effects. METHOD We as...

Gender-typed behaviors and interests were investigated in 26 girls, aged 2-10 years, affected with congenital adrenal hyperplasia (CAH) and in 26 unaffected girls matched for age. Girls with CAH were more interested in masculine toys and less interested in feminine toys and were more likely to report having male playmates and to wish for masculine careers. Parents of girls with CAH rated their ...
