Preeclampsia research presentation

  1. 1. IS THERE A LINK BETWEEN THE DIET OF PREGNANT WOMEN AND THE RISK OF DEVELOPING PREECLAMPSIA?
  2. 2. AIMS <ul><li>No specific aetiology has been discovered for preeclampsia. </li></ul><ul><li>This study aims to identify whether there is a link between overall diet and the risk of developing preeclampsia </li></ul>
  3. 3. WHAT IS PREECLAMPSIA? <ul><li>Affects between 3% and 10% of pregnant women </li></ul><ul><li>hypertension (≥ 140/90 mmHg) with proteinuria (≥ 1+ on urine dipstick) after 20 weeks of gestation </li></ul>
  4. 4. WHAT ARE THE DANGERS? <ul><li>Perinatal Mortality </li></ul><ul><li>Intrauterine growth restriction of the fetus </li></ul><ul><li>Preterm labour </li></ul><ul><li>In the developed world there is a fivefold increase of </li></ul><ul><li>perinatal mortality of infants born to preeclamptic </li></ul><ul><li>mothers </li></ul><ul><li>Maternal Death </li></ul><ul><li>One of the leading causes </li></ul><ul><li>Responsible for 10-15% of maternal deaths in </li></ul><ul><li>the developed world </li></ul><ul><li>Responsible for 20-80% of maternal deaths in </li></ul><ul><li>the developing world </li></ul>
  5. 5. RISKS OF PREECLAMPSIA <ul><li>There are defined independent risks for preeclampsia </li></ul><ul><ul><li>hypertension </li></ul></ul><ul><ul><li>obesity </li></ul></ul><ul><ul><li>diabetes </li></ul></ul><ul><ul><li>DIET? </li></ul></ul>
  6. 6. METHODOLOGY <ul><li>This will be a descriptive quantitative study to identify whether there is a link between the diet and nutritional supplements of pregnant women (prior to and throughout their pregnancy) and the occurrence of preeclampsia. </li></ul>
  7. 7. METHODS <ul><li>Sample – 1,000 women from a variety of maternity settings </li></ul><ul><li>Inclusion criteria – women that fit the definition of pre-eclampsia </li></ul><ul><li>Exclusion criteria – women who have pre-determined risk factors to pre-eclampsia </li></ul><ul><li>Instrument – food frequency questionnaire </li></ul><ul><li>Data collection – education by research assistants 4 weeks after birth </li></ul>
  8. 8. EXAMPLES OF QUESTIONS
  9. 9. DATA ANALYSIS <ul><li>Questionnaire to be coded to enable data analysis </li></ul><ul><li>Interpretation – to include frequency distribution </li></ul><ul><li>Multivariate pattern analysis </li></ul><ul><li>Cluster analysis </li></ul>
  10. 10. EXPECTED OUTCOMES <ul><li>This study may bring to light food groups that are risk factors for preeclampsia </li></ul><ul><li>Subsequent risk could be reduced by implementing valid and researched nutritional advice based on this research </li></ul><ul><li>This in turn could reduce neonatal and maternal mortality rates </li></ul>
