Salivary cortisol measures are increasingly being incorporated into large-scale, population-based, or epidemiological research, in which participants are selected to be representative of particular communities or populations of interest, and sample sizes are in the order of hundreds to tens of thousands of participants. These approaches to studying salivary(More)
In 156 older adults, day-to-day variations in cortisol diurnal rhythms were predicted from both prior-day and same-day experiences, to examine the temporal ordering of experience-cortisol associations in naturalistic environments. Diary reports of daily psychosocial, emotional, and physical states were completed at bedtime on each of three consecutive days.(More)
In a community sample of 52 adolescents, multilevel growth curve modeling was utilized to examine whether within-person changes in momentary mood states, and individual differences in trait emotional functioning, were related to adolescent cortisol levels in naturalistic settings. Salivary cortisol levels were measured seven times a day on two typical(More)
In 70 middle-class mothers of 2-year-old children, individual differences in mothers' morning cortisol levels, cortisol decreases across the day and average cortisol levels were predicted from demographic and medical control variables, maternal relationship functioning and home and work demands. For two days, salivary cortisol levels were measured in the(More)
Levels of the stress-sensitive hormone cortisol increase dramatically in the first 30-40min after waking, an effect known as the cortisol awakening response (CAR). There is considerable cross-sectional evidence that psychosocial stress is associated with an increased CAR, and the CAR has been found to be altered in the presence of stress-related diseases,(More)
Associations between demographic characteristics, school schedules, activity choices, family functioning, and sleep behaviors were estimated using nationally representative time-diary data from 2,454 children (ages 5.5 to 11.9 years) and adolescents (ages 12.0 to 19.1 years). For weekdays, African American adolescents, Asian children, and those with earlier(More)
PURPOSE To identify potential physiological pathways to racial disparities in health outcomes, this study uses cortisol data collected from a community sample of 255 adolescents to examine whether there are racial/ethnic differences in cortisol slopes and levels across the waking day in naturalistic settings. METHODS This study uses salivary cortisol data(More)
In a middle-class sample of mothers of 2-year-olds, adult attachment classifications measured in the Adult Attachment Interview (AAI) were related to maternal self-reported emotional well-being and observed parenting behavior, and the potential mediating and moderating roles of maternal emotion were tested. Mothers classified as dismissing on the AAI(More)
In identifying environmental factors affecting children’s development, researchers have typically focused on the quality of children’s home or family environments. Less attention has been paid to environmental stability as a factor influencing children’s well-being. This is partially due to outdated notions of children’s living arrangements and to the fact(More)
BACKGROUND The question of whether neighborhood environment contributes directly to the development of obesity and diabetes remains unresolved. The study reported on here uses data from a social experiment to assess the association of randomly assigned variation in neighborhood conditions with obesity and diabetes. METHODS From 1994 through 1998, the(More)
