Chapter 1C
 Be able to evaluate the design of studies
used to determine health risk factors,
including sample selection and sample size
used to collect data that are both valid and
reliable.
 Know how factors such as genetics, age and
gender increase the risk of CVDs
 Sample size must be bigger (number of
people involved)
 Investigate one variable, keep other variable
constant(control).
 Some are carried out over a long time
(longitudinal study)
 Ex. Munster Heart Study – 10856 men, 36-65
ages, Europe; Framingham Study – many
similar American citizens.
 Metadata analysis - When data from all the
available studies in a particular area are
analysed
 These studies are excellent resource when
investigating whether there is a genetic factor at
work, any differences between them is
environmental.
