Q

Cross-sectional/prevalence study

A

A study that examines the relationship between diseases (or other health characteristics) and other variables of interest as they exist in a defined population at one particular time

Q

Case control study

A

A study in which a series of persons with a disease (cases) are compared to a group without the disease (controls) as to characteristics (exposure or risk factors) which might predict or cause the disease

Q

Cohort study

A

A study in which persons who are initially free of the disease or outcome condition under study, but who vary related to one or more factors (exposure or risk factors) are followed over a period of time (longitudinal) and observed for the occurrence of the disease or condition

17
Q

Experimental/quasi-experimental study

25
Q

26
Q

Types of measures of rates

A

  2. Prevalence rate
  3. Crude rates
  4. Characteristic of specific rate
  5. Adjusted or standardized rate
27
Q

Incidence rate

A
  • Rate of change from non-diseased state to the diseased state among persons at risk
  • Numerator is only new cases
  • Denominator is restricted to those at risk of becoming a new case
28
Q

Prevalence rate

A
  • Proportion of the population that has a condition at some given time
  • Numerator is number of existing cases at a given point in time
  • Denominator is the best estimate of the population at risk at the same point in time
29
Q

Crude rates

A

Summary rate based in the actual number of events in a total population over a given time

30
Q

Adjusted or standardized rate

A

Summary rates that have undergone statistical transformation to permit fair comparison between groups differing in some characteristic that may affect the risk of disease

31
Q

Types of measures of association

A
  1. Rate ratio
  2. Odds ratio
  3. Prevalence rate ratio
  4. Pearson product moment correlation
32
Q

Rate ratio

A
  • RR
  • aka relative risk or risk ratio
  • RR= incidence exposed/ incidence unexposed
33
Q

Odds ratio

A
  • OR

- aka relative odds, cross product ratio

34
Q

Odds

A

The probability of occurrence of an event to that of nonoccurrence

35
Q

Disease odds ratio

A

The ratio of the odds in favor of disease among the exposed to the odds in favor of disease among the unexposed

36
Q

Prevalence rate ratio

A
  • PRR

- PRR= prevalence exposed/ prevalence unexposed

37
Q

Pearson Product Moment Correlation

A

Estimate of the relationship between variable scores based on scores for those two variables for the sample

38
Q

40
Q

Why conduct research

A
  1. To prevent occupational illnesses, injuries and disability
