Brief Summary:
Overweight and obese men in rural Northeast Nebraska are an unrepresented, at-risk group exhibiting rising rates of cardiovascular disease, poor access to preventive care, and a rural milieu that contributes to their sedentary physical activity and unhealthy diet. This study proposes to use a pragmatic randomized controlled trial and community engaged research approaches to 1) determine the feasibility and acceptability of a commercially available, smart phone self-monitoring app (premium-version) plus text-based coaching and daily weighing via Wi-Fi scale intervention for achieving weight loss, 2) determine preliminary efficacy of this intervention group to a comparison group receiving only a self-monitoring app (basic-version) in achieving the outcomes of weight loss (kilogram) and improved dietary and physical activity behaviors (secondary) at 3 and 6 months post-baseline, and 3) determine quantitative and qualitative indicators of community capacity to support a contextually relevant weight loss intervention. Eighty men (ages 40-69) with body mass index of 28 or higher, randomly assigned (1:1 ratio) to intervention group or comparison group. Men will complete baseline assessments (weight, % body fat, body mass index height, blood pressure, health history, dietary intake, physical activity frequency/intensity) and receive orientation to the mobile technologies (app features, text messaging, Wi-Fi scale). Men will track their dietary intake, physical activity, and weight on the app for 12 weeks. After the 3-month intervention, post-measure assessments (weight, % body fat, BMI, dietary intake, PA frequency/intensity, technology usability surveys) will be collected at 3 and 6 months post-baseline. At 6 months post-baseline, two groups (n=8 each) of intervention completers will be purposively selected to share their perceptions of the intervention efficacy in an evaluative focus group. A community advisory board comprising local leaders within the men's social network, together with investigators and rural student nurses will guide community outreach efforts for study recruitment, implementation and evaluation. Study findings will be evaluated with the community to inform local dissemination, future intervention revision, and determination of community capacity for support of a larger clinical trial.

Primary Outcome Measures :
  1. Change in Weight [ Time Frame: Change from baseline weight at 6 months ]
    Weight in kilograms measured per Tanita digital scale (TBF-215 Tanita Corporation of America)

Secondary Outcome Measures :
  1. Change in Fruit and Vegetable Intake [ Time Frame: Change from baseline fruit and vegetable intake at 6 months ]
    daily fruit and vegetable servings (Brief Risk Factor Surveillance Survey written questionnaire- Fruit and vegetable dietary intake module- 6 item (scale range= 1 per day (desired outcome) to 9 (refused)

  2. Change in Beverage Intake Quality [ Time Frame: Change in baseline beverage intake quality at 6 months ]
    sugar-sweetened total beverage energy intake (Brief Questionnaire to Assess Beverage Intake- 15 item: Scale 0= never or less than 1 time per week (desired outcome) to 6= 3 or more times per day

  3. Change in Overall Diet Quality [ Time Frame: Change in baseline overall diet quality at 6 months ]
    dietary intake quality (Lose-It app automated report of dietary quality (fruits, vegetable, whole grain, milk, meat/protein servings as outlined by the 2005 Dietary Guidelines for Americans) as analyzed from self-reported dietary log input)

  4. Change in physical activity [ Time Frame: Change in baseline overall physical activity at 6 months ]
    total steps taken in 24 hour period (Automated app report of total steps measured via gyroscope on smart phone- total step count range 0-10,000 steps (higher step value represents desired outcome of 10,000 steps per day)
