Intensive lifestyle intervention goals can be achieved as effectively with large groups as with small groups.

Objective: The purpose of this study was to assess if group size is associated with weight loss outcomes among participants in an adapted diabetes prevention program.

Methods: Adults at high-risk (N=841) for CVD and diabetes were enrolled in the lifestyle intervention in 2011. Multiple logistic regression analyses were used to identify if group size (smaller group<16 participants; larger group ≥16 participants) was independently associated with weight loss outcomes among participants.

Implementation of diabetes prevention programs in rural areas: Montana and south-eastern Australia compared.

Objective: To identify the key elements that enabled the Greater Green Triangle Diabetes Prevention Project (GGT DPP) and the Montana Cardiovascular Disease and Diabetes Prevention (CDDP) programs successful establishment and implementation in rural areas, as well as identifying specific challenges or barriers for implementation in rural communities.

Methods: Focus groups were held with the facilitators who delivered the GGT DPP in Australia and the Montana CDDP programs in the USA. Interview questions covered the facilitators' experiences with recruitment, establishing the program, the components and influence of rurality on the program, barriers and challenges to delivering the program, attributes of successful participants, and the influence of community resources and partnerships on the programs.

Factors associated with the maintenance or achievement of the weight loss goal at follow-up among participants completing an adapted diabetes prevention program.

Aims: This study evaluated factors associated with achievement or maintenance of a 7% weight loss goal post intervention among adults at high-risk for cardiovascular disease (CVD) and diabetes who participated in an adapted Diabetes Prevention Program (DPP) intervention.

Materials And Methods: High-risk adults completed the intervention in 2008 or 2009 (N=466). In 2010, we conducted a follow-up survey of participants to assess characteristics, behaviors and barriers associated with the maintenance or achievement of the weight loss goal.
