Data Collection Challenges

• False Answers
• Example no smoking when actually a smoker
• Ought to exaggerate negative affect on LBW for
  those in the no exposure category

• Incomplete forms/fields
• Example smoking field not completed
• If random, should be little or no effect
• If more likely in smokers, ought to decrease
  proportion of LBW births associated with tobacco
  use as well as decrease representativeness of
  LBW rates for smokers
• If more likely in non-smokers, ought to increase
  proportion of LBW births associated with tobacco
  use
