In our recent COVID-19 survey, we asked participants several questions about their exposure to the COVID-19 virus. Most participants reported not having been diagnosed with COVID-19, with very few participants reported having household and/or family members diagnosed with COVID-19. However, 42.69 participants reported knowing at least one friend (and/or classmate) who was diagnosed with COVID-19. More than a quarter (26.03) of the participants reported knowing at least one person from work (co-worker, client, and/or patient) who was diagnosed with COVID-19.
Heritability of affectionate communication: A twins study
Floyd K, York C, Ray CD.
In response to the COVID-19 pandemic, many social restrictions have been put in place in the hopes to slow down the spread of the virus. As a result, many of us have had to make changes in our daily lives accordingly. We examined whether self-perceived change in the amount of physical activity and sleep is associated with mental health.
We were interested in examining the extent to which the COVID-19 pandemic affects mental health. Participants were asked to respond to a number of survey items designed to assess depression, stress, and anxiety.
Neighborhood Deprivation Moderates Shared and Unique Environmental Influences on Hazardous Drinking: Findings from a Cross-Sectional Co-Twin Study.

This research study is being done to examine the impact of COVID-19 on daily activities such as sleep and physical activity. In addition to the risk of COVID-19 infection, statewide restrictions such as stay-at-home orders have resulted in drastic impacts to people’s daily lives. We will collect one week of data 10 times over a 20-month period to measure sleep, daily activities, diet, and emotions. Data collected will allow us to see how COVID-19 impacts life on a day-to-day basis, and how this changes behaviors over time.
In March 2020 we developed a survey to collect information about COVID-19 from all adult members enrolled in the Washington State Twin Registry. The first survey completed is the baseline survey, and a follow-up survey will be sent out beginning in April 2020.
Purpose of the study
In light of the impact of the COVID-19 pandemic and the corresponding social restrictions to society, we aimed to examine the extent to which participants in WSTR are impacted by the recent events. Here is a brief summary of selected results. We would also like to thank the WSTR twins for participation and their continued support of the WSTR.

The contact information update form sent out during the 2018 thank you mailing received many responses from twins indicating that they wanted an event where they could meet other twins and learn about research being done by the WSTR. On June 19, 2019 we held the first Twins Get Together event at WSU Everett. 47 twins (21 complete pairs) attended this free evening event. Food was provided, and twins had the chance to talk with other twins and read about our research studies. We gave a short presentation about why twin studies are important, our past and present research, and addressed some of the frequently asked questions that we receive from twins, such as questions about zygosity (whether twins are identical or fraternal). Finally, we played a fun game of twin-themed BINGO which led into time for the twins to share stories with each other about their unique experiences as a twin.
We received positive feedback and will be planning similar get togethers for twins living near other WSU campuses. We are also in the early planning stages of a large celebration of twins to take place in the summer of 2020.
Not only is it the end of 2019, it’s also the end of a decade of incredible growth for the Washington State Twin Registry (formerly the University of Washington Twin Registry). Below we summarize some highlights of the past 10 years, as well as the past year.

Decade in Review
On September 30, 2009, the University of Washington Twin Registry was awarded a large economic recovery grant which provided funding to increase the size of the Registry and available data. Over the past decade, the Registry has nearly tripled in size, adding over 6,000 new pairs of twins. In 2013, we modified our procedures to allow volunteers and twin children to join. In 2014, we held our first TwinFest event at the University of Washington. In 2015, the Registry moved from the University of Washington to Washington State University and became the Washington State Twin Registry (WSTR). Today, there are 9,761 twin pairs in the WSTR — 8,980 pairs are still actively participating. Our members reside in all 50 US states plus the District of Columbia, and around the world.
Year in Review
In 2019, we added 198 new pairs of twins. We had 6 active studies, and 1,407 unique twin pairs participated in those studies. 14 peer-reviewed publications were accepted. Our website had 171,537 visits from 151,838 users, and our Facebook page has 1,329 likes. We held a small get together at WSU Everett in June, which gave local twins the opportunity to meet other twins and learn about our research.
Coming in 2020!
Our second TwinFest event will be held August 8, 2020 in Everett, Washington. As we have updates, they will be posted on our website and on the Facebook event page. If you and/or your business would be interested in contributing, please send an email to Ally Avery.
As always, thank you for your continued support of and participation
in the Washington State Twin Registry!
