  3. PCOS BASICS • Prevalence of PCOS is 7% -and rising Norman et al ,Lancet 2007 • Increases risk of cardiometabolicdisturbances • Insulinresistance • Dyslipidaemia • Diabetes Ehrmann et al, JCEM 2006 • Obesity present in 50-70% of cases Azziz et al, JCEM 2004

  4. Lecture Summary Why consider lifestyle? Which interventions? Outcomes Conclusions

  5. Endocrine Impact of Obesity • Obesity associated with increased insulin resistance • High serum insulin may drive increased androgen production • Insulin resistance associated with suppression of SHBG Women with PCOS and obesity have higher T4 than PCOS alone Peripubertal obesity associated with 2 fold increase in T4 levels Hoeger K, Clin Obstet Gynecol, 2007

  6. Impact of obesity of clinical, hormonal and metabolic features of PCOS Hoeger K, Clin Obstet Gynecol, 2007

  10. Risks of Infertility Treatment in the Obese Patient • Difficulty in ultrasound monitoring • Complications during oocyte retrieval • Difficult embryo transfer • Increased risk thromboembolic complications

  12. Meta-analysis: 720 women with PCOS vs 4505 controls OR 95% CI Gestational Diabetes: 2.94 1.70-5.08 Pregnancy induced hypertension: 3.67 1.98-6.81 pre-eclampsia 3.47 1.95-6.17 Pre-term birth 1.75 1.16-2.62 Peri-natal mortality 3.07 1.03-9.21

  13. SO: WHAT SHOULD WE DO ABOUT IT? ..and why bother?

  15. Which diet? 12 week energy restriction diet Randomised to high or low protein diet RESULTS: Both interventions improved cyclicity, lipid profile and IR : Mean weightloss 7.5% LP diet: HDLs decreased 10% : FAI increased 44% CONCLUSIONS: Both diets work! High protein diet may have slight advantages

  16. Diet or Exercise- or both?

  17. Why Bother? Hoeger K, Clin Obstet Gynecol, 2007

  18. Moment of caution…

  19. 10 women, 18-40 years, BMI >28, indication for IVF Diet from day14 or day 21 of previous cycle to day of OPU 4 patients withdrew Mean duration of diet: 27-41 days Weight loss: 5.3-8.2 kg (mean 6.3% of body weight) 3 patients : total fertilization failure Tsegareli et al 2006 Fertil Steril

  20. Do womenwith PCOS have poorerpericonceptionaldiet? • Cross-sectional study in patients about to undergo IVF • 25 women with PCOS and 222 control women. • Linear regression analysis of validated dietary questionnaire Brussel, ter Schouw, Macklon

  21. Do womenwith PCOS have poorerdiet in general? • Case control study in 84 cases versus 79 age matched controls • Linear regression analysis of validated dietary questionnaire PCOS Controls p Age 47 48 NS BMI 32 29 0.004 Fasting Insulin (uIU/ml) 17.8 14.7 0.006 Energy intake (kcal) 1754 1762 NS Protein(g) 66 63 NS CHO(g) 205 211 NS Fat(g) 75 73 NS Ever smoker 48% 48% NS Wright et al, Int J Obesity 2004

  22. CONCLUSIONS 1

  23. CONCLUSIONS 2

  24. ´Before any intervention is initiated, preconceptional counselling should be provided emphasizing the importance of life style, especially weight reduction and exercise in overweight women, smoking and alcohol consumption´.

  25. CONCLUSIONS 3 • Larger RCTS needed to assess impact • of interventions. • 2. MORE EMPHASIS ON PREVENTION: • focus on lifestyle and diet in adolescent girls • 3. Build lifestyle interventions into reproductive treatment pathways • 4. Invest effort and money into lifestyle programs
