Outcome measures
Primary outcome
The primary parameters are objective and subjective indicators of physical,
emotional, cognitive and social functioning. These indicators include among
others: self-reported functional limitations, depressive symptoms, loneliness,
thinking about or planning the end of life, and general cognitive functioning.
Secondary outcome
A broad range of paramaters will be included in the data collection. These
paramaters can be used in specific data analyses as outcomes, as confounding
variables or as mediating or moderating factors. For a more elaborate list of
measurements we refer to the LASA Cohort Profile (Huisman et al., 2011), which
is included as an attachment. A new element in the follow-up measurements is a
daily calendar with questions about pain, wellbeing, sleep and appetite.
Background summary
Important shifts in social circumstances, developments in medical care and in
the welfare state have a major impact on the way that people grow old and
influence their functioning in old age. Because of such shifts it remains of
great importance to investigate trajectories of functioning in older Dutch
adults. It can be expected that there is large heterogeneity in these
trajectories and longitudinal observational research is needed to identify the
trajectories of functioning and the consequences of these trajectories in terms
of welbeing and care use of older adults.
Study objective
The aim of the study is to expand an existing infrastructure for scientific
research, i.e. a longitudinal observational study, for investigating physical,
emotional, cognitive and social trajectories of functioning, their determinants
and their consequences.
Study design
Observational cohort study
Study burden and risks
Data collection consists of an interview that is administered by trained
interviewers in the house of the respondent. The interview consist of validated
questionnaires and tests for physical and cognitive functioning. The interview
will take on average 1 hours to complete. In addition, respondents are asked to
fill-out a daily calendar for a week, with questions about the amount of pain,
the quality of sleep, wellbeing and appetite the respondent experienced.
We consider the most burdensome aspects of the data collection to be the
general cognitive tests and questions about planning and thinking about the end
of life, because these may be confronting to some respondents.
Our measurements are observational and non-invasive. In general the risks
associated with participation in the study will be minimal but for frail older
adults the data collection may be more burdensome. To avoid the burden of a
full data collection in these respondents, we offer as alternatives for these
respondents to participate in a short telephone interview, to have a proxy
participate in a short telephone interview, or to skip one follow-up
measurement alltogether. All respondents have participated in the LASA study
previously and are used to the data collection and procedures of the research.
There will be no specific therapeutic effects for the respondents of
participating in the study.

Inclusion criteria
This study is a follow-up study among respondents who participated in the LASA study before. The original selection of these respondents is based on a random sample of: a) respondents aged 55-84 years at baseline in 1992, and b) respondents aged 55-64 years at baseline in 2002. The sample was drawn from 9 municipalities across the Netherlands. For the current study, all respondents who were born in 1941 or in previous birthyears and who remain in the LASA study will be included for additional and more frequent LASA follow-up measurements.
Exclusion criteria
