Journal ArticleDOI

Genetic and environmental variation in educational attainment: an individual-based analysis of 28 twin cohorts.

Karri Silventoinen, +86 more
- 29 Jul 2020 - 
TL;DR: Both genetic and environmental factors shared by co-twins have an important influence on individual differences in educational attainment, and the effect of genetic factors on educational attainment has decreased from the cohorts born before to those born after the 1950s.
Journal ArticleDOI

Differences in genetic and environmental variation in adult BMI by sex, age, time period, and region: an individual-based pooled analysis of 40 twin cohorts.

Karri Silventoinen, +116 more
TL;DR: The heritability of BMI decreased and differences in the sets of genes affecting BMI in men and women increased from young adulthood to old age, despite large differences in mean BMI and variances in BMI.
Journal ArticleDOI

Association of current and former smoking with body mass index: A study of smoking discordant twin pairs from 21 twin cohorts.

Maarit Piirtola, +67 more
- 12 Jul 2018 - 
TL;DR: The net effect of smoking and subsequent cessation on weight development appears to be minimal, i.e. never more than an average of 0.7 kg/m2.
Journal ArticleDOI

The CODATwins Project: The Cohort Description of Collaborative Project of Development of Anthropometrical Measures in Twins to Study Macro-Environmental Variation in Genetic and Environmental Effects on Anthropometric Traits

Karri Silventoinen, +125 more
TL;DR: In this paper, a new research project was proposed to analyze the variation of heritability estimates of height, BMI and their trajectories over the life course between birth cohorts, ethnicities and countries, and study the effects of birth-related factors, education and smoking on these anthropometric traits and whether these effects vary between twin cohorts.
Journal ArticleDOI

Genetic and environmental influences on adult human height across birth cohorts from 1886 to 1994

Aline Jelenkovic, +109 more
- 14 Dec 2016 - 
TL;DR: The findings do not support the hypothesis that heritability of height is lower in populations with low living standards than in affluent populations, nor that herigenicity of height will increase within a population as living standards improve.
