Funding Information:
This study is funded by a five-year National Institute of Nursing Research, National Institutes of Health grant (grant no 1R01NR010589), with supplemental funding approved from a RSF grant from The Nebraska Medical Center and the University of Nebraska Medical Center, Omaha, Nebraska, for lipid and glucose testing, and from The Hygenic Corporation Thera-Band Academy for elastic bands. These funding bodies did not have any input into the design of the study, the collection or analysis of data, the preparation of this manuscript, or the decision to submit this manuscript for publication. The authors thank Matt Gotschall, President, Central Community College-Columbus, NE for agreeing to provide physical space for the project and to Deepak Khazanchi, Associate Dean, College of Information Science and Technology, University of Nebraska-Omaha, Omaha, NE for agreeing to design the intervention website and the data base.

N2 - Background: Weight loss is challenging and maintenance of weight loss is problematic among midlife and older rural women. Finding effective interventions using innovative delivery methods that can reach underserved and vulnerable populations of overweight and obese rural women is a public health challenge. Methods/Design. This Women Weigh-In for Wellness (The WWW study) randomized-controlled trial is designed to compare the effectiveness of theory-based behavior-change interventions using (1) website only, (2) website with peer-led support, or (3) website with professional email-counseling to facilitate initial weight loss (baseline to 6 months), guided continuing weight loss and maintenance (7-18 months) and self-directed weight maintenance (19-30 months) among rural women ages 45-69 with a BMI of 28-45. Recruitment efforts using local media will target 306 rural women who live within driving distance of a community college site where assessments will be conducted at baseline, 3, 6, 12, 18, 24 and 30 months by research nurses blinded to group assignments. Primary outcomes include changes in body weight, % weight loss, and eating and activity behavioral and biomarkers from baseline to each subsequent assessment. Secondary outcomes will be percentage of women achieving at least 5% and 10% weight loss without regain from baseline to 6, 18, and 30 months and achieving healthy eating and activity targets. Data analysis will use generalized estimating equations to analyze average change across groups and group differences in proportion of participants achieving target weight loss levels. Discussion. The Women Weigh-In for Wellness study compares innovative web-based alternatives for providing lifestyle behavior-change interventions for promoting weight loss and weight maintenance among rural women. If effective, such interventions would offer potential for reducing overweight and obesity among a vulnerable, hard-to-reach, population of rural women. Trial Registration. ClinicalTrials.gov: NCT01307644.
