  6. INTRODUCTION 4. ... arised: agricultural airborne pesticide sprays do attain inhabited areas (no report) Highly significant associations with health endpoints NCPH NIEH NPHMOS

  7. OBJECTIVE To evaluate the associations of pesticide sprays with respiratory symptoms - of 7–11 year old children - in 40 villages of an area of Heves county - in 2001 NCPH NIEH NPHMOS

  8. METHODS 1. Allergic symptoms - house dust - pollen - animal hair, feather - food - medicine - other - diagnosis: by a doctor? NCPH NIEH NPHMOS

  11. METHODS 4. Bronchitic symptoms regular cough - in autumn-winter - mornings - days/nights - daily, >3 months - with sputum NCPH NIEH NPHMOS

  12. METHODS 5. Asthmatic symptoms - in the last 12 months - wheezing - dry cough at night - asthma - ever diagnosed by a doctor NCPH NIEH NPHMOS

  23. DISCUSSION 1. Whether it is really possible? - to check retrospectively - flight documentations - to check prospectively - biological monitoring NCPH NIEH NPHMOS

  24. DISCUSSION 2. Chance - high p-values! Bias - recall bias? Confounding - not probable NCPH NIEH NPHMOS

  25. SUMMARY 1. - Pesticide sprays do attain inhabited areas - Respiratory symptoms - 7–11 y children - N=1819 survey questionnaires NCPH NIEH NPHMOS

  26. SUMMARY 2. - allergic and neurotic symptoms - prevalences: 21.8%, 20.3% - pesticide sprays attaining inhabited areas: 9% - odds ratios: 2.13*** (2.23***), 2.19*** (2.33***) NCPH NIEH NPHMOS

  27. SUMMARY 3. - head mucosal, bronchitic, asthmatic sy.-s - prevalences: 46.3%, 15.5%, 14.1% - odds ratios: 1.51*, 1.93**, 1.82* NCPH NIEH NPHMOS
