| Study Overview | The primary objective of the English Longitudinal Study of Ageing (ELSA) is to collect longitudinal multidisciplinary data from a representative sample of the English population aged 50 to 100 at recruitment. ELSA was developed as a companion study to the Health and Retirement Study (HRS) in the USA and documents the experience of growing old in England in the 21st century. The study collects both objective and subjective data relating to health and disability, biological markers of disease, economic circumstance, social participation, networks and well-being. The Covid-19 study is a follow-up study based on the sample of the regular ELSA study Waves to collect data from more than 10,000 ELSA participants, all aged 50 years and over, asking them about their experiences of the COVID-19 crisis. The first wave of data collection took place in June/July 2020 and the second wave started on 4th November 2020, and will be completed by mid-December and looks at changes in participants’ experiences as the COVID-19 crisis evolves. |
| #Subjects at Baseline | Sample size at recruitment: 12,099, comprising 11,391 core members, 636 partners aged <50 years and 72 new partners aged ≥50 years. |

| Key Study References | |
| Population Based Study? | Yes |

| Were participants included prior to development of MCI (may refer to controls only)? | Yes |
| How is data collected? | Face‐to‐face for core and nurse visit, face‐to‐face or telephone interview for exit interview per informant’s preference. Proxy interviews account for c. 2% of all interviews. Interviews are conducted face-to-face by an interviewer using computer-assisted interviewing (CAPI), combined with self-completion questionnaires completed using pen and paper (PAPI). A CAPI interview and collection of bio-measures by a qualified nurse have been carried for all participants at waves 2, 4 and 6 and for half of the participants in waves 8 and 9. |
| Who carries out data collection? | Interviewers and Clinical Staff: Nurses for clinical visits. |
| Does this take place in participants' homes or at a central location? | Home or a residential care home or similar establishment where a participant at the first ELSA interview has moved there. |
| Do participants take part individually or are families/partners involved? | One age‐eligible family unit is chosen per address. Interviews are sought with both members of couples in age‐eligible units (the Core member and Core Partner). |
| Dementia cases ascertained as part of study: | No |
| Diagnosis based on review of existing clinical data | No |
| Was diagnosis/primary outcomes made blind to exposure variables? | No |
| How many times followed up? | 9 |
| # Subjects at Follow-up | Wave 2: 9,432 main interviews (8780 core). Wave 3: 9,771 main interviews (8810 core). Wave 4: 11,050 main interviews (9886 core). Wave 5: 10,274 main interviews (9090 core). Wave 6: 10,601 main interviews (9169 core). Wave 7: 9666 main interviews (8249 core). Wave 8: 8445 main interviews (7223 core). Wave 9: main interviews:8736 (7289 Core) |
| Study start date | 01/01/2002 00:00:00 |
| Is study ongoing? | Yes |
| Is study still recruiting? | Those aged 50-51 at any given wave will be 52-53 by the next wave, therefore a refreshment sample of people in their early 50s will be needed if the sample is to fully represent those aged 50+. The ELSA sample has been refreshed five times now, at waves 3, 4, 6, 7 and 9 |
| Inclusion criteria | Membership of a participating private residential household in England any of the the 1998, 1999 and 2001 Health Surveys for England (HSE) in which at least one person had agreed to a follow-up and at the time of the first wave of fieldwork had an adult aged 50 years or older. Partners who were aged <50 years and those who had joined the household since HSE were invited for interview. |
| Exclusion criteria | All Core Members were eligible for subsequent Wave interview (personal or proxy) unless they had died or moved outside of Great Britain (Wales or Scotland) or had explicitly asked to not be re-contacted. |
