Religiosity, Acculturation, and Preterm Birth in Mexican-Origin Women: A Pilot Study

Introduction Explanations for racial disparities in preterm birth (PTB) are elusive, especially when comparing high rates in some racial groups with low rates in Mexican-immigrant women. The purpose of this study was to examine potential protective factors against PTB such as religiosity and acculturation. Methods This study was a prospective investigation of Mexican- and U.S.-born pregnant women. Women were recruited from a low-income-serving prenatal clinic in Texas. Survey instruments included socioeconomic variables, acculturation, and religiosity/spirituality (R/S). Logistic regression was used to examine the associations between acculturation, religiosity, and PTB. Because of the low prevalence of PTB in our sample, we were not able to adjust for confounding characteristics. Results Ninety-one low-income women, mostly Mexican immigrants, participated in the study. PTB in our sample was lower than the national average in the United States (5.5% vs. 9.9%) and was positively but moderately associated with high R/S. R/S scores were high, particularly for frequency of attendance, prayer, and religious coping. Women with lower acculturation had higher scores on the religiosity measures. Conclusion Further research is needed with a larger sample to include other ethnic and racial minorities to more fully understand the relationships between acculturation, religiosity, and PTB.
