Association of Current and Former Smoking With Body Mass Index: a Study of Smoking Discordant Twin Pairs From 21 Twin Cohorts
(Public Library Science, 2018-07-12)
Background
Smokers tend to weigh less than never smokers, while successful quitting leads to an increase in body weight. Because smokers and non-smokers may differ in genetic and environmental family background, we ...
Birth size and gestational age in opposite-sex twins as compared to same-sex twins: An individualbased pooled analysis of 21 cohorts
(Nature Publishing, 2018-04-19)
It is well established that boys are born heavier and longer than girls, but it remains unclear whether birth size in twins is affected by the sex of their co-twin. We conducted an individual-based pooled analysis of 21 ...
Associations Between Birth Size and Later Height From Infancy Through Adulthood: an Individual Based Pooled Analysis of 28 Twin Cohorts Participating in the Codatwins Project
(Elsevier Ireland, 2018-05)
Background: There is evidence that birth size is positively associated with height in later life, but it remains unclear whether this is explained by genetic factors or the intrauterine environment.
Aim: To analyze the ...
Genetic and environmental factors affecting birth size variation: a pooled individual-based analysis of secular trends and global geographical differences using 26 twin cohorts
(Oxford University Press, 2018-05-19)
Background: The genetic architecture of birth size may differ geographically and over
time. We examined differences in the genetic and environmental contributions to birthweight,
length and ponderal index (PI) across ...
Association between birth weight and educational attainment: an individual-based pooled analysis of nine twin cohorts
(BMJ Publishing Group, 2018-05-30)
Background There is evidence that birth weight is
positively associated with education, but it remains
unclear whether this association is explained by familial
environmental factors, genetic factors or the intrauteri ...
