      While most children display a normal development, some children experience developmental delays compared to age specific development milestones assessed during school entry examination. Data exist on prevalence of delays in single areas, but there is lack of knowledge regarding the clustering patterns of developmental delays and their determinants.
    • Effect of Disease Definition on Perceived Burden of Acute Respiratory Infections in Children: A Prospective Cohort Study Based on Symptom Diaries.

      Acute respiratory infections (ARIs) are among the most frequent childhood diseases in Western countries. Assessment of ARI episodes for research purposes is usually based on parent-administered retrospective questionnaires or prospective symptom diaries. The aim of our analysis was to compare the effect of ARI definitions on the corresponding disease burden in a prospective cohort study using symptom diaries.

      Even minor abnormalities of early child development may have dramatic long term consequences. Accurate prevalence rates for a range of developmental impairments have been difficult to establish. Since related studies have used different methodological approaches, direct comparisons of the prevalence of developmental delays are difficult. The understanding of the key factors affecting child development, especially in preschool aged children remains limited. We used data from school entry examinations in Bavaria to measure the prevalence of developmental impairments in pre-school children beginning primary school in 1997-2009.
