Abstract Introduction:<\b>
South African educators are at greater risk for non-communicable diseases than the general South African population. Studies show the effectiveness of SMS text message-based interventions for weight loss, physical activity (PA), glycaemic control and hypertension management. Aim: To compare effectiveness of a single tailored print communication and SMS-text messaging intervention vs standard feedback following a wellness day health risk assessment in South African educators. Methods:<\b>
Schools (N=27) were randomised into intervention (INT, N=13) or control (N=14, CTL) conditions, with 571 educators presenting for baseline assessment. The INT group (n=156) received a single printed tailored letter focused on lifestyle goals and barriers, and 8 tailored , bi-directional SMS messages over 5 months. After 5 months, 59% of educators were re-tested (N=349). The “as-per-protocol” results are reported. Results:<\b>
INT resulted in a significantly greater decrease in BMI and in the proportion educators who were overweight or obese compared to CTL (8.9% vs. 1.1%, P<0.001). PA increased in both groups, with significantly more educators meeting PA guidelines in the INT group compared to CTL (112.8% vs 58.9%, P<0.001). The prevalence of hypertension was significantly reduced in INT vs CTL groups (P<0.001). Conclusion:<\b>
A potentially scalable, tailored print communication and SMS text messaging intervention may be more effective for changing physical activity health risk behaviours, than standard feedback following health risk assessment in an “at risk” group such as South African educators.
