title: [Laryngotracheitis, recurrent laryngotracheitis and asthma in children: features of ontogenesis and feeding in the first months of life].
abstract: Objective of research was to study features of ontogenesis and feeding in the first months of life in children with laryngotracheitis (LT), recurrent laryngotracheitis (RLT) and asthma.
  
  
  METHODS
  Questionnaire-based survey was performed to collect data on anamnesis of 1004 children aged 6-14 years (575 children with a history of LT, 60 children with asthma, and 369 children of control group) pertaining to preeclampsia in mothers, history of birth asphyxia, preterm birth and feeding during the first months of life in children. Children with LT were divided into two groups: 458 children with 1-3 episodes of LT and 117 children with RLT (4 or more episodes of LT).
  
  
  RESULTS
  The frequency of preeclampsia among mothers of children with RLT exceeded the corresponding frequency among mothers of children with 1-3 episodes of LT and children of control group in 2.1 and 2.8 times, respectively. The frequency of birth asphyxia or preterm birth among children with RLT exceeded the corresponding frequency among children with 1-3 episodes of LT and children of control group by a factor of 2. The frequency of breastfeeding initiation after 24 hours of birth among children with asthma or RLT exceeded the corresponding frequency among children with 1-3 episodes of LT (in 1.4 and 1.5 times, respectively) and among children of control group (in 2.4 and 2.6 times, respectively).
  
  
  CONCLUSIONS
  The frequency of preeclampsia in mothers, birth asphyxia, preterm birth and late initiation of breastfeeding among children with RLT exceeded the corresponding frequency among children with 1-3 episodes of LT and children of control group. There was no significant difference between the frequency of preeclampsia in mothers, birth asphyxia, initiation of breastfeeding among children with RLT and children with asthma. Formula feeding in the first months of life was equally often observed among children with LT, RLT and asthma and significantly exceeded the corresponding percentage among children in control group.
