- Objectives This study aimed to investigate the associations
of combined parental low educational level and
combined parental unemployment on the risk of preterm
birth (PTB) in Korea.
Methods Data on 427,857 singleton births were obtained
from the National Birth Registration (NBR) database in
2003 and analyzed. Parental education and parental
employment status were combined as exposure for analysis.
Place of birth, sex, marital status, parental age and
parity were included for analysis of unconditional multiple
logistic regressions. PTB was defined as birth before a
gestational age of 37 complete weeks.
Results Group of the lowest educational level, below high
school, had the highest odds of PTB in both father and
mother in multivariable analysis [odds ratio (OR) 1.15 and
1.16, respectively]. After combining parental educational
status for the multivariable analysis, the highest probability
of PTB was in families where both parents had below
college level education (OR 1.22). As for paternal
employment, the multivariable analysis showed an
increased rate of PTB occurred where the father was
unemployed (OR 1.11). After combining the employment
status of both parents, the multivariable analysis revealed
that PTB was only significant in families where both parents
were unemployed (OR 1.09).
Conclusions We found that combined parental low educational
level and combined parental unemployment increased the likelihood of preterm birth.
