Purpose: The World Health Organization states the most crucial period for maternal and newborn survival is between labor, delivery and postnatal phases. This has drawn attention for many researchers to the weight determinants have on women accessing and utilizing care after childbirth worldwide. Every day, all around the world, close to thousands of women die from complications related to pregnancy and childbirth and 99% of maternal and newborn mortality occur in low and middle- income countries. The aim of this study is to examine the proportion of women who utilize postpartum care services and the significant factors affecting utilization of postpartum care in Marinduque, Philippines. Methods: A cross sectional, analytical study was conducted using a self-administered questionnaire among 402 women of age 15 to 49 years old who attended either of the 5 Rural Health Units (RHUs) within six municipalities located Marinduque, Philippines. Descriptive, chi-square and logistical regression analysis were used to determine which factors best explained and predicted postpartum care utilization. All the data was coded using Microsoft Excel 2010 and exported to SPSS statistical software package version 21 for analysis. Results: Among 402 participants that received postpartum care, the majority of respondents 366 (91.0%) reported the use of postpartum care services. Regarding women’s perception to receive the postpartum care, respondents who disagree with the statement that “postpartum care is not necessary if there are no perceived health problems” (OR=3.739; 95%CI=1.474-9.485) remained significant and are almost 4 times more likely to use postpartum care than those who agree. Mothers who had prenatal care in health centers (p = 0.032), those who had more than or equal to 4 prenatal care (p = 0.006), delivered in a health facility (p = 0.003), and were attended by a skilled health worker during delivery (p = 0.000) were more likely to use postpartum care services compared to other groups. Conclusion: Although the use of postpartum care services is low in the developing countries, the utilization of postpartum services is high in the Philippines. The majority of respondents identified postpartum care to be important, and utilization rates to be higher compared to other studies. However nearly (one-fourth) of those women thought that postpartum care after delivery was only necessary if pain or complications became evident. Other studies identifying determinants of postpartum utilization also reveal this concept of "perception" and how it influences whether women chose to utilize services. By recognizing these trends of perception, it presents policy and health service provider implications for women’s reproductive health knowledge and practice, for the delivery of postpartum care services, and for establishment of postpartum care guidelines. Further research on the perception of women on postpartum care may help to determine the root cause of their perceptions and be able to implement strategies to correct these perceptions.
