Objective To investigate the use of contraceptive methods， and to evaluate maternal healthcare services utilization among women within 2 years in Pudong New Area of Shanghai.

Methods A cross-sectional survey was conducted using a questionnaire for women at different postpartum periods who visited a community health clinic with their children from June to November 2021. Data were analyzed using χ² test and binary logistic regression.

Results Among the 1 946 postpartum women surveyed， 1 934 were either married or cohabiting， and 1 430 had resumed their sexual life. Among women at 4， 6， 12， 18 and 24 months postpartum， the contraceptive prevalence rates （CPR） were 92.34% （193/209）， 92.16% （235/255）， 87.31% （282/323）， 91.95% （297/323） and 90.00% （288/320）， respectively. The modern contraceptive prevalence rates （mCPR） were 87.08% （182/209）， 87.06% （222/255）， 82.04% （265/323）， 83.09% （271/323） and 85.31% （273/320）， respectively， while the unmet contraceptive needs （UMNs） were 7.66% （16/209）， 7.84% （20/255）， 11.46% （37/323）， 6.81% （22/323） and 10.00% （32/320）， respectively. The use rates of long-acting reversible contraceptive （LARC） methods among women at 6， 12， 18 and 24 months postpartum period were 0.39% （1/255）， 2.17% （7/323）， 0.31% （1/323）， and 2.81% （9/320）， respectively. Among all surveyed subjects， 32.17% （626/1 946） had received postpartum contraceptive services only once， while 27.85% （542/1 946） had not received any postpartum contraceptive services. Binary logistic regression analysis indicated that the use of contraceptive methods among postpartum women was associated with whether relevant educational services were received after childbirth and during postpartum home visits （all P<0.05）.

Conclusion Postpartum women have unmet needs for contraception. Contraceptive guidance at the 42-day postnatal healthcare visit needs to be further strengthened and postpartum contraceptive education could be integrated into the pregnancy care. The quality and effectiveness of contraceptive education during delivery and postpartum home visits， and even at the 42-day postnatal healthcare visit need to be further explored.
