Goldfarb DS, Avery AR, Beara-Lasic L, Duncan GE, Goldberg J. Background Nephrolithiasis is a complex phenotype influenced by both genetic and environmental factors. Previously we found a genetic component to stone disease using a sample of male twin pairs. We now report on the genetic contribution to stones in a sample of female and male […]
Peng H, Zhu Y, Strachan E, Fowler E, Bacus T, Roy-Byrne P, Goldberg J, Vaccarino V, Zhao J. Objective DNA methylation has been associated with both early life stress and depression. This study examined the combined association of DNA methylation at multiple CpG probes in five stress-related genes with depressive symptoms, and tested whether these […]
Silventoinen K, Jelenkovic A, Hopper JL, Busjahn A, Cozen W, Mack TM, Sumathipala A, Harris JR, Goldberg JH, Harden KP, Duncan GE, Buchwald D, Turkheimer E, Kaprio J, et al. Whether monozygotic (MZ) and dizygotic (DZ) twins differ from each other in a variety of phenotypes is important for genetic twin modeling and for inferences […]
Silventoinen K, Jelenkovic A, Cozen W, Mack T, Sumathipala A, Christensen K, Busjahn A, Duncan GE, Buchwald D, Goldberg JH, Hopper JL, Sung J, Turkheimer E, Kaprio J, et al. Background Genes and the environment contribute to variation in adult body mass index [BMI (in kg/m2)], but factors modifying these variance components are poorly understood. […]
Jelenkovic A, Sumathipala A, Christensen K, Hopper JL, Cozen W, Mack TM, Sung J, Duncan GE, Buchwald D, Harris JR, Goldberg JH, Kaprio J, Silventoinen K, et al. Human height variation is determined by genetic and environmental factors, but it remains unclear whether their influences differ across birth-year cohorts. We conducted an individual-based pooled analysis […]
Silventoinen K, Jelenkovic A, Busjahn A, Cozen W, Mack TM, Craig JM, Harden KP, Duncan GE, Buchwald D, Goldberg JH, Kaprio J, et al. Background Both genetic and environmental factors are known to affect body mass index (BMI), but detailed understanding of how their effects differ during childhood and adolescence is lacking. Objectives We analyzed […]
Jelenkovic A, Craig JM, Sumathipala A, Harden KP, Cozen W, Mack TM, Hopper JL, Duncan GE, Buchwald D, Sung J, Harris JR, Busjahn A, Goldberg JH, Kaprio J, Silventoinen K, et al. Height variation is known to be determined by both genetic and environmental factors, but a systematic description of how their influences differ by sex, age and […]
Melhorn SJ, Mehta S, Kratz M, Tyagi V, Webb MF, Noonan CJ, Buchwald DS, Goldberg J, Maravilla KR, Grabowski TJ, Schur EA Background Neural responses to highly energetic food cues are robust and are suppressed by eating. It is not known if neural responsiveness to food cues is an inherited trait and possibly even one […]
Jelenkovic A, Craig JM, Sumathipala A, Harden KP, Cozen W, Mack TM, Hopper JL, Duncan GE, Buchwald D, Sung J, Harris JR, Busjahn A, Goldberg JH, Kaprio J, Silventoinen K, et al. A trend toward greater body size in dizygotic (DZ) than in monozygotic (MZ) twins has been suggested by some but not all studies, and this difference […]
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 Silventoinen K, Craig JM, Sumathipala A, Harden KP, Cozen W, Mack TM, Hopper JL, Duncan GE, Buchwald D, Sung J, Harris JR, Busjahn A, Goldberg JH, Kaprio J, et al.

Buchwald D, Kaprio J, Hopper J, Sung J, Goldberg J, Fortier I, Busjahn A, Sumathipala A, Cozen W, Mack T, Craig J, Harris J The International Network of Twin Registries (INTR) aims to foster scientific collaboration and promote twin research on a global scale by working to expand the resources of twin registries around the […]
Myhre R, Kratz M, Goldberg J, Polivy J, Melhorn S, Buchwald D, Cummings DE, Schur EA Genetic, physiological, and psychological factors can affect food intake, but twin studies can distinguish inherited from environmental contributors. We examined the influence of attempted cognitive control of eating (“restrained eating”) on levels of appetite-regulating hormones. Sixteen female, monozygotic twin pairs, […]
Vitaliano P, Strachan E, Dansie E, Goldberg J, Buchwald D Informal caregiving can be deleterious to mental health, but research results are inconsistent and may reflect an interaction between caregiving and vulnerability to stress.We examined psychological distress among 1,228 female caregiving and non-caregiving twins. By examining monozygotic and dizygotic twin pairs discordant for caregiving, we […]
Godfrey KM, Strachan E, Dansie E, Crofford LJ, Buchwald D, Goldberg J, Poeschla B, Succop A, Noonan C, Afari N There is a dearth of knowledge about the link between cortisol and pain sensitivity. We examined the association of salivary cortisol with indices of cold pain sensitivity in 198 female twins and explored the role of […]
Barclay NL, Watson NF, Goldberg J, Buchwald D Diurnal preference changes across the lifespan. However, the mechanisms underlying this age-related shift are poorly understood. The aim of this twin study was to determine the extent to which genetic and environmental influences on diurnal preference are moderated by age. Seven hundred and sixty-eight monozygotic and 674 dizygotic […]
Watson NF, Harden KP, Buchwald D, Vitiello MV, Pack AI, Strachan E, Goldberg J We used quantitative genetic models to assess whether sleep duration modifies genetic and environmental influences on depressive symptoms. Participants were 1,788 adult twins from 894 same-sex twin pairs (192 male and 412 female monozygotic [MZ] pairs, and 81 male and 209 female […]
Strachan E, Hunt C, Afari N, Duncan G, Noonan C, Schur E, Watson N, Goldberg J, Buchwald D The University of Washington Twin Registry is a unique community-based registry of twin pairs who join specifically to participate in scientific research. It was founded in 2002 to serve as a resource for investigators throughout the scientific […]
Watson NF, Harden KP, Buchwald D, Vitiello MV, Pack AI, Weigle DS, Goldberg J To examine whether sleep duration modifies genetic and environmental influences on body mass index (BMI), investigators conducted a genotype-environment interaction twin study. the dataset included twin pairs from the University of Washington Twin Registry (1,088 pairs, 604 monozygotic, 484 dizygotic; 66% female; […]
Duncan GE, Dansie EJ, Strachan E, Munsell M, Huang R, Vernez Moudon A, Goldberg J, Buchwald D We used a classical twin design and measures of neighborhood walkability and social deprivation, using each twin’s street address, to examine genetic and environmental influences on the residential location of 1389 same-sex pairs from a US community-based twin […]
Dansie EJ, Heppner P, Furberg H, Goldberg J, Buchwald D, Afari N Data from primary care and community samples suggest higher rates of post-traumatic stress disorder (PTSD) among individuals with chronic fatigue syndrome (CFS). This study investigated the co-occurrence of CFS, PTSD, and trauma symptoms and assessed the contribution of familial factors to the association of […]
