Prenatal Drinking in the Northern Plains: Differences Between American Indian and Caucasian Mothers.

ABSTRACT:

Introduction

Prenatal alcohol exposure is associated with adverse pregnancy outcomes such as fetal alcohol spectrum disorders. The study characterizes the pattern and risk factors of alcohol use during pregnancy for American Indian and Caucasian mothers in the Northern Plains.

Methods

A general population of pregnant women was recruited from 5 sites, including 2,753 Caucasians and 2,124 American Indians (2006-2017). Alcohol consumption was based on self-report using a modified Timeline Followback interview, administered 3-4 times during pregnancy and 1 month postpartum. Risk for prenatal drinking was calculated using logistic regression models after controlling for demographics, reproductive history, prenatal care, mental health, and SES. The analysis was conducted in 2019.

Results

More Caucasian mothers consumed alcoholic beverages during pregnancy than American Indians (63% vs 52%), whereas more American Indian mothers were binge drinkers than Caucasians (41% vs 28%). American Indian mothers had a lower risk of drinking in the second and third trimesters and postpartum, but a higher risk of binge drinking in the first trimester compared with Caucasians. Frequent relocation increased the risk of prenatal alcohol use among American Indian mothers, whereas age, marriage, income, parity, and fertility treatment affected the risk of prenatal drinking among Caucasian mothers.

Conclusions

Alcohol use was more prevalent among Caucasian mothers. Among those who consumed alcohol during pregnancy, American Indian mothers consumed larger quantities. Change of residence was found to be the sole risk factor for prenatal drinking among American Indian mothers, whereas different and multiple risk factors were found for Caucasian mothers.

Project description:BackgroundBreast cancer is the most common cancer in the United States and the second leading cause of death for American Indian women. American Indian women have lower rates of breast cancer screening than other racial groups, and disparities in breast cancer mortality and survival rates persist among them. To address this critical need, a culturally appropriate, accessible, and personalized intervention is necessary to promote breast cancer screening among American Indian women. This study used mobile health principles to develop a mobile web app-based mammogram intervention (wMammogram) for American Indian women in a remote, rural community in the Northern Plains.ObjectiveThis study aimed to assess the feasibility and efficacy of the wMammogram intervention, which was designed to motivate American Indian women to undergo breast cancer screening, as compared with the control group, who received an educational brochure.MethodsUsing community-based participatory research (CBPR) principles and a multipronged recruitment strategy in a randomized controlled trial design, we developed the wMammogram intervention. This study involved 122 American Indian women aged between 40 and 70 years, who were randomly assigned to either the intervention group (n=62) or the control group (n=60). Those in the intervention group received personalized and culturally appropriate messages through a mobile web app, while those in the control group received an educational brochure. We measured outcomes such as mammogram receipt, intention to receive breast cancer screening after the intervention, and participants' satisfaction with and acceptance of the intervention.ResultsA significantly higher proportion of women who received the wMammogram intervention (26/62, 42%; P=.009) completed mammograms by the 6-month follow-up than the control group (12/60, 20%). The wMammogram intervention group, compared with the control group, reported significantly higher ratings on perceived effectiveness of the intervention (t120=-5.22; P<.001), increase in knowledge (t120=-4.75; P<.001), and satisfaction with the intervention (t120=-3.61; P<.001). Moreover, compared with the brochure group, the intervention group expressed greater intention to receive a mammogram in the future when it is due (62/62, 100% vs 51/60, 85%) and were more willing to recommend the intervention they received to their friends (61/62, 98.4% vs 54/60, 90%) with statistically significant differences.ConclusionsThis study shows the feasibility and efficacy of the wMammogram intervention to promote breast cancer screening for American Indian women in a remote, rural community-based setting. Findings suggest that, with advancements in technology and the ubiquity of mobile devices, mobile web apps could serve as a valuable health intervention tool that builds upon low-cost technology and enhances accessibility and sustainability of preventive care to help reduce breast health disparities experienced in hard-to-reach American Indian populations.Trial registrationClinicalTrials.gov NCT05530603; https://clinicaltrials.gov/ct2/show/NCT05530603.
