There is increasing interest in sex differences in immunity during childhood. To examine differences in hospital admission rate for infections between the sexes, we conducted a register-based cohort study of all Danish residents aged 0-14 years from 1977-2014. We examined total admission rate, rates for admission by infection category, time-period, season and duration of admission according to age and sex.
Infectious diseases are common in pediatric patients and are a major cause of pediatric hospital admissions.
The latest study that examined all infectious disease hospitalizations in the whole Danish population of children, was made over 10 years ago and examined the time trend in first-time admissions for infections in children aged 0-5 years from 1980-2003, but variations in admissions according to sex was not examined.
There is increasing interest in potential sex differences in immunity. Knowledge about how admissions for infections in the Danish population of children are distributed by sex, age and different infection categories, could be important for designing optimal preventive programs in both sexes and identifying potential fields for further research.
The primary aim of this study was to examine how the rate of hospital admissions for infections varies according to age and sex in Danish children. Secondarily, we examined if the variation in the rate of hospital admissions for infections according to age and sex was affected by season, type of infection, duration of admission and if admission rates changed over calendar years for categories of infections and duration of admission.
We identified our cohort through databases from Statistics Denmark. We identified 3,691,295 children aged 0-14 years eligible for participation. Of these, 1,296 (0.035%) were excluded due to lack of information on sex, giving us a cohort of 3,689,999 children.
