Can certified health professionals treat obesity in a community-based programme? A quasi-experimental study

Baukje Miedema et al. BMJ Open. .

Abstract

Objective: To test the effectiveness of a non-pharmaceutical programme for obese participants in a rural Eastern Canadian Province using certified health professionals.

Design: A prospective quasi-experimental design with repeated premeasure and postmeasure.

Participants: 146 participants with obesity (body mass index >30 kg/m(2)) from rural and urban communities in an Eastern Canadian Province were divided into four groups.

Intervention: A 6-month intensive active community-based lifestyle intervention (InI) delivered by Certified Exercise Physiologists, Certified Personal Trainers and Registered Dietitians, followed by 6 months of self-management. A second intervention (InII) was nested in InI and consisted of group-mediated cognitive-behavioral intervention (GMCBI) delivered by an exercise psychologist to two of the four InI groups.

Outcomes: (1) Improving health outcomes among the participants' preactive and postactive 6-month intervention and self-management period, (2) Documenting the impact of InII (GMCBI) and location of the intervention (urban vs rural).

Results: The 6-month active InI significantly improved cardiovascular health for participants who completed the intervention. InII (GMCBI) significantly lowered the attrition rate among the participants. The self-management period was challenging for the participants and they did not make further gains; however, most were able to maintain the gains achieved during the active intervention. The location of the intervention, urban or rural, had little impact on outcomes.

Conclusions: A community-based programme utilising healthcare professionals other than physicians to treat obese patients was effective based on premeasure and postmeasure. During the self-management phase, the participants were able to maintain the gains. Psychological support is essential to participant retention.
