Multicomponent approaches to promoting healthy behaviours in people with Type 2 diabetes: an integrative review.

The progression of diabetes-related complications can be delayed with multifactorial interventions that support healthy behaviours. However, many initiatives have focused on educational or individual-level activities and observed limited or modest sustained improvements in healthy behaviours. A multicomponent approach to behaviour change, which simultaneously considers numerous social determinants of health across multiple socio-ecological model levels, may be required to achieve meaningful health outcomes for people with Type 2 diabetes. Applying a multicomponent method of inquiry, this integrative review aimed to synthesize the evidence on interventions using multifactorial interventions to promote healthy behaviours in adults with Type 2 diabetes. Interventions promoting healthy behaviours in adults with Type 2 diabetes were considered for the review. A total of 7205 abstracts retrieved from eight databases were screened for inclusion. Thirteen articles were included, of these 11 achieved statistically significant clinical and/or behavioural changes in outcomes such as glycated haemoglobin, blood pressure, cholesterol, diet and physical activity. The multifactorial components utilized included the coordination of multi-disciplinary health care teams, in-person self-care classes, group activities, incorporation of peer-leaders, the development of community partnerships, economic relief and built-environment support. The proportion of included studies published within recent years indicates a trend towards multicomponent interventions and the growing recognition of this approach in promoting public health. Our findings provide early support for the potential of extending intervention components beyond educational, individual-level and health care system-level focus to incorporate multiple socio-ecological model components that contribute to the system of influence affecting the health of people with diabetes.
