BACKGROUND Electrophysiologic studies have found abnormalities of alpha asymmetry in depressed adults and offspring of depressed parents, which have been hypothesized to be vulnerability markers of depression. Resting electroencephalogram (EEG) was measured in grandchildren participating in a multigenerational high-risk study. METHODS Electroencephalogram from 12 electrodes at six homologous ...

A methodology is introduced for numerical evaluation, with any given accuracy, of the cumulative probabilities of the proportion of genome shared identical by descent (IBD) on chromosome segments by two individuals in a grandparent-type relationship. Programs are provided in the popular software package Maple for rapidly implementing such evaluations in the cases of grandchild-grandparent and g...

This study surveyed college-aged grandchildren as to the frequency of their communication with a grandparent using various media. Face-to-face (FtF) and telephone communication were used more frequently than written media, but all were used fairly frequently. Communication using all media was more frequent when the grandparent or grandchild initiated interaction as opposed to the parent. Relati...

This paper examines the intergenerational stake hypothesis in the grandparent-grandchild relationship. The hypothesis predicts that older generations will perceive more closeness in a relationship than younger generations. Grandparent-grandchild dyads are surveyed concerning various aspects of their relationship. Using measures of closeness and an established typology of grandparent-grandchild ...

PURPOSE This study determined the prevalence of grandparents raising grandchildren who are living in rental housing and explored the sociodemographic characteristics and challenges faced by such renters. DESIGN AND METHODS Data were obtained from the Census 2000 Supplementary Survey, a nationally representative survey of 700,000 households with a response rate of 96.8%. Frequencies and bivari...

The major purpose of this study was to identify predictors of grandparent caregiver health status. Additional purposes were to describe the physical and emotional health of grandparent caregivers and the perceived benefits of support group attendance. A convenience sample of 42 grandparents was recruited from support groups. Data were collected through telephone interviews. Grandparents who had...

Campylobacter jejuni is a major cause of bacterial food-borne infection in the industrial world. There is evidence that C. jejuni is present in eggs and hatchery fluff, opening the possibility for vertical transmission from hens to progeny. Poultry operations in Iceland provide an excellent opportunity to study this possibility, since breeding flocks are established solely from eggs imported fr...

There is limited research on the links between grandparenting and adolescents' well-being, especially from the perspective of the adolescents. The study examined whether grandparent involvement varied in two-parent biological, lone-parent, and step-families and whether this had a different contribution to the emotional and behavioral adjustment of adolescents across different family structures....
