Previous research has suggested that cesarean section may be associated with an increased risk of developing obesity in childhood, adolescence and adulthood. Yet, previous studies have been small or unable to differentiate between elective and non-elective cesarean section. Therefore, using a population-based cohort the purpose is to examine the associations between vaginal delivery, elective and non-elective cesarean section on the risk of developing obesity in young adulthood among Swedish young singleton males. Using the Swedish medical birth registry, the recorded mode of delivery and indication of delivery which will be matched to those males who perform military conscription, where their body mass index is recorded. The investigators hypothesize that there will be an elevated risk of obesity in those born with non-elective cesarean section, as a function of confounding, while those born with elective cesarean section will not have a higher risk of obesity than those born with vaginal delivery.
Categories of body mass index [ Time Frame: Measured at conscription (~18 years of age) ]
World health organisation categories of body mass index: underweight BMI<18.5, normal weight BMI 18.5-24.9, overweight BMI 25-29.9 and obese BMI>30. Weight at conscription was measured using standardized scales and height was assessed using stadiometers in a standardized manner.
Secondary Outcome Measures :
Continuous body mass index [ Time Frame: Measured at conscription (~18 years of age) ]
