Clinical Trial Summary

Age with Health is a longitudinal cohort study aimed to examine trajectories of health, disability and wellbeing and their determinants for Spanish ageing population. Two waves have carried out so far. Wave 1 (2011-2012) and Wave 2 (2014-2015). Wave 3 will be conducted 2018, including also a new cohort of participants (Called 2018 Cohort). The study will provide reliable measures of population ageing and adult health in Spain - and will provide the basis for cross-country comparisons with longitudinal studies conducted in other countries.

Clinical Trial Description

Study Design:

A prospective cohort general population study. Three study Waves

Sample:

Wave 1: A nationally representative sample of non-institutionalized adults aged 18 years or older from the Spanish population was collected (with an over-sampling of people aged 50+ years). A multi-stage clustered design was employed; four strata based on the number of inhabitants of the municipalities were built for each of the 17 Spanish autonomous communities. Clusters were selected within the strata with a probability of inclusion relative to their size. Within each cluster, households were randomly selected from a list of all households. In case there was more than one individual from the corresponding age group in the household, a random method was employed to select the individual participant. A total of 4,753 respondents were interviewed and signed the written consent.

Wave 2: Wave 1 sample was re-interviewed (Wave 2) in 2014-2015. The mean follow-up period was 3.5 years (SD = 0.18). A total of 2,528 individuals were re-interviewed. The response rate in the second wave was 69.5%. This cohort will be re-interviewed after 3.5 years (Wave 3).

Wave 3: Following the same sampling methods than in Wave 1 approximately 3000 participants from Madrid and Barcelona will be interviewed for the first time.

Data collection:

Face-to-face interviews by Computer-Assisted Personal Interviewing at the respondents' homes by trained interviewers. All interviewers receive a standardized training. Data quality control is also performed.

Main objective:

To assess trajectories of general health, disability and well-being in Spanish ageing population.

Secondary objectives:

To identify trajectories of healthy ageing (in terms of psychical health, mental health, functioning and well-being) in Spanish adult population as well as their determinants To analyse prevalence and impact of chronic health conditions, mental health problems, well-being and loneliness on mortality in Spanish adult population.

To determine risk factors for incidence and persistence of mental and physical health problems in Spanish ageing population.

Hypothesis:

The trajectories of health, functioning and well-being will be encompassed by relevant environmental factors such as social support, loneliness and health care utilization, personal factors (socio-demographic characteristics, healthy lifestyles, and high cognitive reserve among others) and other biological and health-related factors (weight, height, waist circumference, executive functions, blood pressure, grip strength, vision acuity, presence of mental and physical health problems and quality of life). ;
