Physical activity and nutrition program for adults with metabolic syndrome: Process evaluation

Abstract

IntroductionThe Vietnam Physical Activity and Nutrition (VPAN) program aimed to improve physical activity and nutrition for adults aged 50–65 years with Metabolic Syndrome in Vietnam. The VPAN program consisted of a range of resources and strategies, including an information booklet, resistance band, face-to-face education sessions, and walking groups. This process evaluation assessed the participation, fidelity, satisfaction, and reasons for completing and not-completing the VPAN. MethodsData were collected by mixed-methods from a sample of 214 intervention participants. Quantitative data were collected via surveys (n=163); qualitative data via face-to-face exit interviews with intervention program completers (n=10) and non-completers (n=10), and brief post education session discussions. ResultsMost participants (87%–96%) reported the program resources and strategies useful, assisting them to increase their physical activity level and improving their diet. The education sessions were the most preferred strategy (97%) with high attendance (>78% of participants). The main reasons for withdrawal were work commitments and being too busy. ConclusionThe evaluation indicated that the program reached and engaged the majority of participants throughout the six-month intervention. The combination of printed resources and face-to-face intervention components was a suitable approach to support lifestyle behavioural change in the Vietnamese population.
