Purpose
To examine the association between sociodemographic factors and preference for birth mode in nulliparous women in China.
Methods
A total of 4606 women before or in early pregnancy were recruited from 2013 to 2016 in the Shanghai Birth Cohort Study. Generalized linear regression was used to examine the association of sociodemographic characteristics with preferred birth mode and actual cesarean section (CS) without clinical indications in 2713 nulliparous women, and the changes from preference of vaginal birth to actual CS without clinical indications in 2369 nulliparous women.
Results
After controlling for potential confounders, preference for CS was associated with older maternal age [31–34 years: adjusted risk ratio (ARR) 2.73, 95% confidence interval (CI) 1.56–4.78; ≥ 35 years: 6.27, 3.28–12.01, p for trend < 0.0001] and lower level of education (below junior college vs college or above: 1.51, 1.10–2.09). Older maternal age (≥ 35 years: 3.37, 1.74–6.50), born in city or township (city vs countryside: 3.18, 1.93–5.24; township vs countryside: 1.97, 1.06–3.66), and lower level of education (below junior college vs college or above: 1.38, 1.01–1.88) were significantly associated with a CS without clinical indications. Women who preferred vaginal birth but had an actual CS without clinical indications were more likely to be older (≥ 35 years: 4.30, 1.44–12.83) and born in city (city vs countryside: 2.89, 1.33–6.30).
Conclusions
Older age, lower education level, and being born in city or township were risk factors for CS without clinical indication in China.
