Focus Groups
A total of 4.9% (16/325) men and 1.6% (2/129) women from the intervention arm, with a mean age of 62.4 (SD 10.3) years, participated in the focus groups after completing the 6-month program. Thematic analysis demonstrated that participants identified 5 enablers in the program: active reminders to lead a healthy lifestyle, encouragement of dietary changes, encouragement of more physical activity, the ability to share the messages with friends and family, and the feeling of support that the program offered. There was consensus that the content of the messages was appropriate and pitched at the right level. The content on physical activity and diet was considered particularly helpful. Responses illustrating these themes are provided in Table S3 in
