ObjectiveTo understand the current situation and needs of maternal health care under the two-child policy， and to provide possible measures for two-child maternal health care.

MethodsThe questionnaire survey on the two-child maternal health care was conducted during the initial diagnosis in the department of obstetrics， and the pregnancy outcome was investigated through medical records after delivery.

ResultsAmong 719 pregnant women， the proportion of multiparas was 28.0%. The proportion of increased age （27.4%） and cesarean section （34.0%） in the multiparas were significantly higher than those in the primiparas （6.6% and 26.1%， respectively）. The main differences in the risk assessment between multiparas and primiparas were scarred uterus and age. The most important indicator of multiparas’ caesarean section was scarred uterus. The proportions of pre-pregnancy examination （55.2%）， recording in the Shanghai Maternal Health Care System （95.3%）， and participation or willingness to participating in pregnancy school （77.2%） among primiparas were significantly higher than those among multiparas （26.3%，93.0%，and 47.4%， respectively）.

ConclusionMultiparas do not pay attention to the standard maternal health care， and are lack of knowledge about the second child birth. Maternal health care should be strengthened for multiparas by health education， such as social media， distribution of reading materials and face-to-face consultation.
