Physical Activity Promotion

Group physical activity promotion had a 52% probability of being the most cost-effective option at £20,000 per QALY in the multiway CEAC. Physical activity promotion yielded an estimated QALY gain of 0.060. Individual physical activity promotion had an expected probabilistic intervention cost of £267. Group physical activity promotion had an expected probabilistic intervention cost of £157. Long-term evidence for physical activity promotion came from two musculoskeletal-condition studies. Many existing eHealth interventions targeting sedentary behaviour have primarily promoted physical activity. Physical activity promotion may indirectly reduce sedentary time by reallocating time away from sitting. Meeting physical activity targets may not fully offset the harms of prolonged sitting. Physical activity promotion was one of the three intervention categories that met the modelling criteria. Physical activity promotion interventions aim to increase total activity time through structured activity.
