  4. &The quantitative data was analyzed by ANOVA (q test), while the qualitative data (mode of delivery and sex) was analyzed by χ2 test among all these four groups. S1 group: exogenous DHA-rich n-3 PUFAs supplementation at the early pregnancy (0–12 week), S2 group: exogenous DHA-rich n-3 PUFAs supplementation at the middle pregnancy (13–27 week), S3 group: exogenous DHA-rich n-3 PUFAs supplementation at the late pregnancy (> 27 week), Control group: non-exogenous DHA-rich n-3 PUFAs supplementation during the whole pregnancy
