Effects of preconception counseling on maternal health care of migrant women in China: a community-based, cross-sectional survey.

Background: Migrants have long been a disadvantaged group in China's health care system, especially in terms of maternal health care. Many studies have explored the factors associated with a lack of maternal health care and found many determinants, including social, economic, behavioral, and environmental factors. However, studies focusing on factors associated with maternal health care have rarely examined preconception counseling (PCC). This study explored factors related to PCC uptake among migrant women, and investigated the association between PCC and maternal health care in migrant women.

Methods: A community-based cross-sectional study was conducted from July to December 2011, in Nanhai, Guangdong Province, and Pinghu, Zhejiang Province, China. A total of 1,012 migrant women who had their most recent pregnancy within 1 year of the survey answered a standardized interviewer-administered questionnaire about maternal health care. Descriptive statistics and multivariable logistic regression were used to analyze the data.

Results: Only 208 (20.6%, 95% confidence interval [CI]: 18.1-23.1%) of 1,012 migrant women had received PCC. Younger age, having more than one child, lack of knowledge of maternal health care and inter-province migration were predictors of a lack of PCC. PCC was associated with higher consumption of folic acid supplements during the preconception period (adjusted odds ratio [AOR] = 2.65, 95% CI: 1.66-4.23). Among migrants who were resident in Nanhai or Pinghu for less than 5 years, PCC was related to better quality prenatal care (AOR = 3.07, 95% CI: 1.79-5.24).

Conclusions: The prevalence of PCC among migrant women was low (20.6%, 95% CI: 18.1-23.1%). Positive associations were found between the receipt of PCC and preconception folic acid supplements and quality prenatal care. Future studies focusing on maternal health care should pay attention to PCC and explore the effects of PCC on maternal health care through intervention studies. Continued efforts to increase PCC in migrants should target specific age groups (20-24 years), families with more than one child, and women who have migrated between provinces, as well as provide in-depth knowledge of maternal health care.
