The emergence of the cortisol circadian rhythm in monozygotic and dizygotic twin infants: the twin-pair synchrony
OBJECTIVE Studies on the influence of genetic factors on the ontogeny of cortisol circadian rhythm in infants are lacking. This study evaluated the influence of twinning and the heritability on the age of emergence of salivary cortisol rhythm. DESIGN AND SUBJECTS A longitudinal study was performed using salivary samples obtained during morning and night, at 2, 4, 8, 12, 16, 20 and 24 weeks of...
متن کاملTwin relationships in old age: A developmental perspective
The relationship development of 133 monozygotic (MZ) and 60 same-sex dizygotic (DZ) older twin pairs was studied retrospectively and contrasted with their other sibling relationships. Results indicate: (i) Since adolescence, MZ twins lived closer to one another and had more frequent contact, social support, and emotional closeness. For both MZ and DZ pairs, contact and emotional closeness decre...
متن کاملHeritability of daytime cortisol levels and cortisol reactivity in children
Individuals differ widely in cortisol output over the day and cortisol reactivity to challenge, both of which are relevant to disease risk. There is limited evidence concerning the heritability of these differences, so we evaluated the heritability of cortisol levels in the afternoon and cortisol reactivity using a twin design. The study involved 80 monozygotic (MZ) and 70 dizygotic (DZ) same-s...
متن کاملDo MZ twins have discordant experiences of friendship? A qualitative hypothesis-generating MZ twin differences study
Using a qualitative monozygotic (MZ) twin differences design we explored whether adolescent MZ twins report discordant peer relationships and, if so, whether they perceive them as causes, consequences or correlates of discordant behaviour. We gathered free-response questionnaire data from 497 families and conducted in-depth telephone interviews with 97 of them. Within this dataset n = 112 famil...
متن کاملThe influence of zygosity and chorion type on fat distribution in young adult twins consequences for twin studies.
An adverse intra-uterine environment has been associated with abdominal fat distribution in singletons. Twins often have a low birth weight and a short gestation. Therefore, they may have an increased risk to develop abdominal obesity. Furthermore, monozygotic monochorionic twins (MZ MC) have a larger intra-pair birth weight difference compared to monozygotic dichorionic twins (MZ DC). If adult...
