Outcome measures
Primary outcome
Health of an ageing population including e.g.: (risk factors of) diabetes,
cardiovascular diseases, asthma and COPD, osteoporosis, physical and cognitive
functioning, incontinence, perceived health and loneliness
Secondary outcome
Not applicable
Background summary
Health at old age is the result of the lifelong exposure to and interplay of
genetics, lifestyle factors, biological risk factors and environmental factors.
In order to study determinants of healthy ageing, cohort studies are needed
with the following characteristics: 1. large and representative, 2. inclusion
from a relative young age, 3. long term follow-up measurements, 4. measurements
on all relevant parameters: life style (e.g. diet, physical activity), risk
factors (e.g. obesity, blood pressure, cholesterol), several common diseases
and quality of life.
Study objective
The general objective of the Doetinchem Cohort Study is to contribute to the
answering of public health questions, now and in the future, by providing basic
data on developments in lifestyle and health problems in the general Dutch
population.
Study design
The Doetinchem Cohort Study presents already 25 years of data collection among
a population cohort of originally 20-59 years of age, and is becoming a unique
source for scientists to study the determinants of old age. The study started
in 1987-1991 and every 5 years participants were measured, with the current
fifth round of measurements ending this year (2012) with full measurement of ca
4500 participants. A sixth round will be carried out in 2013-2017.
Study burden and risks
Earlier participants will be invited for participation in the 5th round.
Participation includes: sending back a response card, having telephone contact
for making an appointment at the local health service in Doetinchem, filling
in questionnaires and a physical examination of 1.5 hours including:
measurement of length, weight, waist and hip circumference, lung function,
blood pressure of arm and ankle, calcaneal quantitative ultrasound measurement,
physical functioning (muscle strenght, balans, chairtest), collection of blood
(for glucose and cholesterol and future research) and a cognitive function
test. Under restriction of additional funding also the following measurements
will be added to the protocol: AGES (skin autofluorescence), hearing tests
(frequency and/or background noise), accelerometer (objective measurement of
physical activity)
