Participant Flow

Spanish general adult population non-institutionalized; aged 18+ years with oversampling of those aged 50+ years and those 80+ years); multi-stage stratified sampling; representative sample.

Respondents unable to undertake the interview because of severe cognitive or physical impairment were administered a shorter version of the questionnaire to a proxy respondent.

Construct: Level of physical activity Scale: Global Physical Activity Questionnaire version 2 (GPAQ v2); It collects information on physical activity participation in three settings (or domains) and sedentary behavior. The responses given by the participants have been converted to Metabolic Equivalent to Task (MET) values. Applying MET values to activity levels allows for calculating total physical activities. Values: Three values of physical activity can be obtained 3=High physical activity 2=Moderate physical activity 1=Low physical activity

Cohort 2011
n=4753 participants at risk
The data comprising the 2011 reference cohort were collected as part of the Collaborative Research on Ageing in Europe (COURAGE in Europe) project between July 2011 and May 2012. It consisted of a representative sample of the Spanish adult population over 50 years of age, with an oversampling of older people and a representative comparison sample of individuals aged 18-49 years. Potential respondents were selected using a stratified, multistage, stratified probability design, by clustered areas without replacement, according to Spanish regions and population size. The primary sampling unit consisted of municipalities. A number of census units (the secondary sampling unit) were chosen from each of them. Age strata were then used to randomly select 10 households within each census unit (the tertiary sampling unit). Finally, a list of household occupants was drawn up, from which one participant was randomly selected following age quotas. Institutionalized persons were not included in the initial interviews. At baseline, 4,753 participants were interviewed, of which 2,528 were interviewed in the second wave (2014-2015), 1,577 in the third wave (2010-2021) and 963 in the fourth wave (2022-2023).
Cohort 2019
n=3002 participants at risk
The sample of the 2019 cohort is a new representative refreshment sample from the provinces of Barcelona and Madrid, to compensate for attrition (e.g., deaths, dropouts) from the 2011 cohort. Household selection was also multistage. At the primary sampling unit level, households were defined using predefined routes and an omission factor. Households were assigned to one of two age groups (i.e., household aged 18-49 years or household aged 50 years or older) and interviewers hand-delivered the invitation letter to the selected households. All residents in the eligible age group were invited to participate in the survey. In this first wave, 3 002 participants joined and in 2022 the second selection of participants for the 2019 cohort was conducted, of which 1 037 participants were interviewed.
