ABSTRACT
<b>Background: </b>Socioeconomic status (SES) is correlated with morbidity and mortality rates, in addition to people of a lower social status. Many of such people have health-related problems and do not undergo a regular health checkup or consult a medical practitioner. We investigated whether a correlation exists between SES, psychological state and the number of weeks of gestation at the time of the first examination. We clarified the influence of SES on the subjects’ life events (e.g. pregnancy and childbirth), in order to understand appropriate support measures.<br><b>Methods: </b>A total of 151 female study subjects were selected from among women hospitalized for postpartum care, who underwent prenatal checkups, and delivered their children in the study center. Questionnaire surveys, one of which involved an interview, were conducted in a cross-sectional manner for the subjects’ during their pregnancy and in the postpartum period.<br><b>Results: </b>The results show that women who perceived financial constraints showed a significantly stronger tendency to develop depression. Multiple logistic regression analysis showed that women whose partners had an educational background of junior high school level underwent their first gestational examination at week 12 or later of pregnancy (odds ratio of 10.99, P = 0.001; 95% confidence interval, 3.15–86.79).<br><b>Conclusion: </b>The present study suggests the importance of observing the correlation between SES and health among pregnant women, such that strategic interventional services can be provided to such persons.
