Abstract
BackgroundWhether children born prematurely are at a high risk of depression is still unknown. The present study examined the risk of depression in children who were born prematurely, by analyzing a national cohort in Taiwan. MethodsAll premature births between January 1, 2000, and December 31, 2010, by using the Taiwan National Health Insurance Research Database. A total of 21,478 preterm children and 85,903 full-term children were enrolled in this study. Sex, level of urbanization of residential area, and parental occupation were considered. We included participants who received a diagnosis of depression in more than two clinical visits or were hospitalized due to depression. ResultsPreterm children had a 2.75-fold higher risk of depression than full-term children (95% confidence interval [CI] = 1.58–4.79, p < 0.001). Sex was not likely to be associated with depression in this study (p = 0.95). The lowest level of urbanization significantly contributed to the risk of depression in preterm children (adjusted hazard ratio = 6.8, 95% CI = 1.63–28.46, p < 0.01). Regarding parental occupation, preterm children whose parents had blue-collar and other occupations had a 3.4- and 6.06-fold higher risk of depression, respectively, compared with other children (blue-collar occupations: 95% CI = 1.04–11.15, p < 0.05; other occupations: 95% CI = 1.71–21.49, p < 0.01). ConclusionsPreterm children had a 2.7-fold higher risk of depression than children born full-term. Early identification, timely psychiatric care, intervention strategies, and support for their families may reduce the complications of mental illness in preterm children.
