Overview of the one-year intervention programme. Note: +2w = 2 weeks from baseline, +3 of +6 m = 3 or 6 months from baseline. Solid bars represent intervention modules that were sent to the intervention group over the course of the 12 m intervention period. No additional information related to diet, exercise or a healthy weight was provided between 12 m - 24 m follow-up period. Both intervention and control group received general newsletters (NL) to increase compliance at 24 m follow up.
