REVIEW…

CROSS-SECTIONAL STUDY

19

Quasi-experimental (ie: control is relevant to outside factors)

Looks at exposure of interest and disease outcome at same point in time

Study on the prevalence of hypertension around the world.

Survey results: 26% of adults have hypertension, with similar proportions for men and women.

The prevalence of hypertension increases strongly with age, especially for women.

Worldwide, the number of adults with hypertension is predicted to increase from 972 million in 2002 to 1,560 million in 2025, as the proportion of elderly people increases.

LONGITUDINAL

20

A study in which the same group of people is studied on 2 or more occasions so that the incidence can be assessed

Requires at least 2 series of measurements among same people at different times to determine progress of the condition over specified time period

Example: Canadian Longitudinal Study on Aging (CLSA) which is designed to examine health patterns and trends among aging Canadians

Examples: Survival rage of women who have undergone breast cancer treatment – study may last 10 years so that success of treatment can be tracked

PROSPECTIVE

21

Planning of entire study is completed BEFORE data is collected and analyzed

Outcomes are then compared

Population is followed through time to see which members develop the disease

Subjects who presently have a certain condition and receive treatment are followed over time and compared with another group who are not affected by the condition

It is an example of analytical research

Example: Smokers vs non-smokers

RETROSPECTIVE

22

Carry out an investigation using observations/data that was collected in the PAST

Used to study rare conditions

“ex post facto” – “after the fact study”

Eg: Case Control Study ie: compare individuals with disease and individuals without disease - look back to determine if variables are related to present differences

An example of analytical research

An epidemiologic study design that assembles study groups after disease occurrence

A design in which factors are derived from data relating to experiences in the past

Example: skin cancer

ANALYTIC STUDY

23

• Study designs that examine groups of individuals in order to make comparisons and associations and to determine causal relationships

ECOLOGIC STUDY

24

Data for exposures and outcomes come from population level rather than from individual

Example: study addressing the question of whether water fluoridation is related to hip fracture

ANSWER

• A) A screening test result that is negative when the individual actually has the disease of interest

• Remember - False-positive test – a screening test result that is positive when the individual does not have the disease of interest
