Background: Certain factors originating from the perinatal and childhood periods are suspected of contributing to the recent increasing trend of childhood type 1 diabetes (T1D) incidence. This study sought to investigate the relationships between various perinatal and childhood risk factors and T1D incidence in young children (<10 years). Methods: We used a nested case-control design based on 1 478 573 live births born in 200005 in Taiwan. Cases were 632 incident cases of T1D between 2000 and 2008. Ten matched controls for each case were randomly selected. Information on various perinatal risk factors was also identified from claim data. Multiple conditional logistic regression was employed to estimate odds ratio (OR) and 95 confidence interval (CI) of T1D. Results: Childhood infection was significantly associated with an increased risk of T1D (OR = 1.46, 95% CI = 1.23 1.73). Increased risk of T1D was also noted in children born to younger mothers (<25 years) (OR = 1.94, 95% CI = 1.342.81), older fathers (>30 years) (OR = 1.56 (95% CI = 1.162.10) to 1.57 (95% CI = 1.192.05), mothers with Caesarean section (CS) (OR = 2.35, 95% CI = 1.52.64), and mothers with gestational diabetes mellitus (OR = 4.36, 95% CI = 2.767.77). Fathers with T1D (OR = 7.36, 95% CI = 1.0257.21) or type 2 diabetes (OR = 1.54, 95% CI = 1.042.26) were observed to substantially increase the risk of offspring T1D. Conclusions: Certain modifiable perinatal factors such as infection and CS may predispose incidence of T1D in young children.
