"sleep and obesity during pregnancy: impacts on breastfeeding success among Indiana's rural mothers"

About the Project

Project Time & Type:
Fall 2014 - DURI
Research area(s):
Basic Science, clinical and translational Research
Project Description:
Breastfeeding rates among rural and urban dwelling families found that low-income women in rural areas were less likely to initiate breastfeeding than women living in urban areas. Approximately 1.8 million people live in rural communities in Indiana, making it the 14th most rurally populated state. These facts support a clear need for increased emphasis on breastfeeding interventions in rural communities of Indiana so that the health of our entire state is enhanced. Our long term goal is to identify factors that prevent successful breastfeeding and to develop behavioral interventions to increase rates of adequate breastfeeding (i.e. exclusive breastfeeding for 6 months, and continued for at least one-year). A longitudinal observational prospective cohort study will be used to determine the relationship of circadian patterns of sleep, activity and salivary melatonin and cortisol during pregnancy to timing to onset of lactation and breastfeeding duration in 50 women (body mass index, BMI>18, but <40). Specific aims of this proposal includes collecting preliminary data to test our hypothesis and answer the following questions: What is the retention rate of the proposed study population?, What is subject compliance rate of the proposed sampling protocol? And what is the efficacy of approach to data collection and statistical analysis? We envision that disruption of the circadian system interferes with initiation of lactation, and thus hypothesize delayed onset of lactation is due in-part to disruption of the mother's circadian system.
Expected Student Contributions:
The student will participate in developing online surveys for mothers recruitment and follow up, monitor mothers data online and contact mothers for some surveys. Students also will participate in data entry and analysis.
