Swedish National study on Aging and Care in Kungsholmen (SNAC-K) COVID-19 Study
These data are collected from 1428 older adults aged 60 and above. The project is embedded in the ongoing Swedish National Study on Aging and Care in Kungsholmen (SNAC-K), a population-based study with regular health assessments since 2001. https://www.snac-k.se/
The SNAC-K COVID-19 study aims to: 1) Estimate the short-term collateral damage on older adults’ health during the first months of the COVID-19 outbreak; 2) Detect the long-term collateral repercussions on older adults health up to two years after the first outbreak; 3) Identify the risk profiles for such collateral damage by integrating the ongoing interview with additional SNAC-K data and registries.
The questionnaire explicitly focuses on the changes in the participants’ health and lives, i.e. collateral damage, since the onset of the pandemic (March 2020). Depending on the interview date, collateral damage is investigated in up to four different time periods: March 2020-June 2020, July 2020-September 2020, October 2020-December 2020, January 2021-present.
The questionnaire is administered via telephone interviews conducted by trained SNAC-K personnel. As of April 2021, the first interview has been conducted with 1428 participants and a follow-up interview has been conducted with 105 of them. 934 follow-up interviews are scheduled to be conducted between April 2021 and August 2021 and an additional 167 by the end of 2021.
