Perceived change in physical activity and mental health during COVID-19: Findings among adult twin pairs
Between March 27 and April 5, 2020, we administered an online survey asking participants a series of questions regarding the changes of health-related behaviors and health outcomes during the early days of the COVID-19 pandemic in the US. Considering that strategies aimed to mitigate the COVID-19 pandemic, such as physical distancing and lock downs, may have unintended consequences on health behaviors (e.g., physical activity, exercise), we explored the relation between individuals’ perceived change in the amount of physical activity and mental health over the short-term.

COVID-19 Follow-up Update #3
In the follow-up survey, we asked participants to self-report the amount of moderate-to-vigorous physical activity (MVPA) they had in the past two week. We wondered if the amount of exercise people are doing during the COVID-19 pandemic was associated with several mental health indicators.

Affectionate Communication findings
We are happy to share that a manuscript using data from the affectionate communication study has been published. Within twin pairs, identical twins were more highly correlated for expressed and received affection than fraternal twins, suggesting genetic influences play a role in affection. Using an ACE model, which is used in twin studies to estimate the contribution of genetics and the environment to a given phenotype such as affection, the study authors determined that 45% of the variance in expressed affectionate communication is heritable (due to genetics), and 0% is explained by the common environment. This means that shared influences such as being raised by the same parents in the same households had no impact on expressed affection. Only 21% of the variance in received affection was heritable. Given that received affection largely depends on others, it is not surprising to see that heritability is lower for this trait. These findings suggest that greater attention should be given to communicative behaviors by considering genetic and biological influences, and not just environmental influences.

COVID-19 Follow-up Update #2
In the follow-up survey, we were interested in whether the number of individuals in a household during lock-down/shelter-in-place has an effect on people’s mental health status. We were particularly curious about whether individuals with children are more worried during this unprecedented time.

Dr. Blue studied Economics and Anthropology at Indiana University (BS, 2003), and Anthropology at the University of Utah (MS, 2005; Ph.D., 2008). Her graduate work focused on the principles of evolutionary and population genetics. She pursued training in statistical genetics as a postdoctoral fellow at the University of Washington (2008). She joined the faculty at the University of Washington in the Department of Medicine, Division of Medical Genetics (2011). She has been the chair of the Young Investigators committee of the International Genetic Epidemiology Society since 2013, joined the Statistical Genetics Program faculty in 2014, and the Institute of Public Health Genomics faculty in 2015. Dr. Blue’s research focuses on identifying genetic variants influencing complex traits, such as Alzheimer Disease and autism spectrum disorder. Her recent work has delved into the complexities of Mendelian traits as well, including oculocutaneous albinism, familial idiopathic pulmonary fibrosis, and others.

Dr. Duncan’s academic training is in physical education (BS, 1992, East Stroudsburg University of Pennsylvania) and exercise physiology (MS, 1994, Ball State University; PhD, 1997, University of Tennessee). Following graduate school, he completed postdoctoral research training (1998-2002) and then joined the faculty at the University of Florida (2002-2003), both in the Department of Medicine, Division of Endocrinology and Metabolism. He joined the Core Faculty of the Nutritional Sciences Program, Department of Epidemiology, University of Washington in July 2003. In June 2015, he accepted a position as Professor in the newly established Elson S. Floyd College of Medicine, and Chair of the Nutrition and Exercise Physiology program at Washington State University – Health Sciences Spokane, where the Washington State Twin Registry is administratively housed. His major focus is related to macro-level influences (built environment, social environment, policies) on physical activity, nutrition, and chronic disease within an ecological framework.

COVID-19 Parents of Twins Survey
This survey is being sent to parents of twins age 13 and younger. This survey will examine how the COVID-19 pandemic is impacting families.
COVID-19 Fear of Crime
The purpose of this survey study is to examine the impact of the COVID-19 pandemic and corresponding social restrictions in place on the daily life and feelings of WSTR twin pairs. Given the widespread statewide social restrictions put in place, it is possible that people’s perceptions and normal interactions within their neighborhoods may have changed. We intend to utilize the survey data to investigate the extent to which safety perception and mood may have changed as a function of the COVID-19 pandemic and the subsequent changes in their social environment. Although we are unable to determine the initial “baseline” of these perceptions, the follow-up survey in May 2021 will provide insight as to how much these perceptions may have changed as the COVID-19 pandemic ends and social restrictions are lifted.
COVID-19 Follow-up Update #1
Purpose of the study
In light of the impact of the COVID-19 pandemic and the corresponding social restrictions to society, we followed up with a sample of our participants to see how they are impacted by the recent events. We would like to thank the WSTR twins for their participation and continued support of the WSTR.
