Plesh O, Noonan C, Buchwald DS, Goldberg J, Afari N To determine whether shared genetic influences are responsible for the association between pain from temporomandibular disorders (TMD) and migraine headache. Data were obtained from 1,236 monozygotic and 570 dizygotic female twin pairs from the University of Washington Twin Registry. TMD pain was assessed with a question […]
Schur EA, Kleinhans NM, Goldberg J, Buchwald DS, Polivy J, Del Parigi A, Maravilla KR We studied whether self-reported intent to exert cognitive control over eating was associated with differences in brain response to food cues, independent of genetic background. Subjects were ten pairs of identical twins in which one twin was a restrained eater […]
Watson NF, Buchwald D, Noonan C, Vitiello MV, Pack AI, Goldberg J We used the community-based University of Washington Twin Registry to investigate the genetic association between circadian type and sleep duration. Habitual sleep duration was obtained by self-report and circadian type was measured using a reduced 5-item Horne–Östberg Morningness–Eveningness questionnaire. Univariate and bivariate genetic […]
Schur EA, Heckbert SR, Goldberg JH We investigated the association of restrained eating with BMI and weight gain while controlling for the influence of genes and shared environment. Participants were 1,587 twins enrolled in the University of Washington Twin Registry (UWTR). Restrained eating was assessed by the Herman and Polivy Restraint Scale. Height and weight […]
Afari N, Noonan C, Goldberg J, Roy-Byrne P, Schur E, Golnari G, Buchwald D Studies have found a modest association between depression and obesity, especially in women. Given the substantial genetic contribution to both depression and obesity, we sought to determine whether shared genetic influences are responsible for the association between these 2 conditions. Data were […]
Schur E, Noonan C, Polivy J, Goldberg J, Buchwald D We examined the relative contributions of genetic and environmental influences to restrained eating. Restrained eating was assessed by the Restraint Scale in a survey mailed to all twins enrolled in the University of Washington Twin Registry. We used structural equation modeling to estimate genetic and non-genetic […]
Schur E, Noonan C, Buchwald D, Goldberg J, Afari N To determine if shared genetic or environmental vulnerabilities could underlie depression and migraine. Depression and migraine headaches frequently coexist and their comorbidity may be due to shared etiologies. Female twins in the University of Washington Twin Registry responded to a mailed survey regarding their health history. Depression […]
Afari N, Wen Y, Buchwald D, Goldberg J, Plesh O The goals of this study were to determine if symptoms of posttraumatic stress disorder (PTSD) are related to the pain of temporomandibular disorders (TMD) in a community-based sample of female twin pairs, and if so, to ascertain if the association is due to the presence […]
Duncan GE, Goldberg J, Noonan C, Moudon AV, Hurvitz P, Buchwald D The health benefits of regular physical activity are well established. However, the relative contribution of heritable and environmental factors to physical activity participation remains controversial. Using a cut-point of 60 minutes of total activity per week, data from the GenomEUtwin project revealed consistent […]
Schur E, Afari N, Goldberg J, Buchwald D, Sullivan PF Prolonged fatigue of ≥1 month duration and chronic fatigue of ≥6 months duration are both commonly seen in clinical practice, yet little is known about the etiology or epidemiology of either symptom. Chronic fatigue syndrome (CFS), while rarer, presents similar challenges in determining cause and […]
Schur E, Afari N, Furberg H, Olarte M, Goldberg J, Sullivan PF, Buchwald D Considerable overlap in symptoms and disease comorbidity has been noted among medically unexplained and psychiatric conditions seen in the primary care setting, such as chronic fatigue syndrome, low back pain, irritable bowel syndrome, chronic tension headache, fibromyalgia, temporomandibular joint disorder, major […]
Afari N, Noonan C, Goldberg J, Edwards K, Gadepalli K, Osterman B, Evanoff C, Buchwald D The University of Washington Twin Registry is a community-based registry of twins identified from the Washington State Department of Licensing. A fortuitous quirk in the Washington State drivers’ license and identification number assignment, and collaborative Washington State laws, permitted […]
Arguelles LM, Afari N, Buchwald D, Clauw DJ, Furner S, Goldberg J Previous studies of the association between posttraumatic stress disorder (PTSD) and chronic widespread pain (CWP) or fibromyalgia have not examined the role of familial or genetic factors. The goals of this study were to determine if symptoms of PTSD are related to CWP […]
Roy-Byrne P, Noonan C, Afari N, Buchwald D, Goldberg J The objective of this study was to identify genetic, familial and environmental contributions to the association between posttraumatic stress disorder (PTSD) symptoms and poor health. A community sample of 1852 twin pairs was assessed for symptoms of PTSD [with the Impact of Events Scale (IES)] and […]
Hallstrand TS, Fischer ME, Wurfel MM, Afari N, Buchwald D, Goldberg J Asthma and obesity are common conditions that are strongly associated. This association might be due to shared genetic or environmental causes. We sought to determine whether a shared genetic cause is responsible for the association between asthma and obesity and to estimate the magnitude […]
