AbstractThis mixed-method study aimed to explore the psychological predictors of long-term adherence to healthy diet and physical activity (PA) recommendations in a community-based lifestyle modification program among Hong Kong Chinese overweight and obese adults. Chinese overweight and obese adults newly enrolled in a self-financed, culturally appropriate lifestyle modification program in Hong Kong were recruited between April 2014 and May 2015. Quantitative data on psychological factors (knowledge, self-efficacy, motivation and stage of change) were collected at baseline and 10-month using validated questionnaires. Adherence to healthy diet and PA recommendations at 10-month were assessed using dietary and PA records. Qualitative data on their experience and opinions towards the program were collected by means of semi-structured interviews and observation. A total of 140 and 26 participants completed the quantitative and qualitative studies, respectively. They reported an overall high level of dietary adherence but low PA adherence. Multivariate analyses revealed that changes in nutrition knowledge and diet stage of change were significant predictors of dietary adherence while changes in PA self-efficacy and PA stage of change were significant predictors of PA adherence. The qualitative findings suggested that the support from therapists enhanced participants’ knowledge and self-efficacy. Participants with high adherence adopted the diet and PA recommendations in their daily lives. The findings of this study help to fill in the knowledge gap of factors related to long-term maintenance of lifestyle changes. On the practical level, the findings have important implications for health care professionals offering individualized lifestyle advice for weight management.
