A hybrid group education and mHealth intervention yielded a non-significant increase in physical activity at 12 months versus routine care (difference 0.95 mg; 95% CI -0.46 to 2.37).

Does a hybrid lifestyle intervention (group education and mHealth) improve physical activity in women with a history of gestational diabetes?
A hybrid group education and mHealth intervention did not significantly increase objectively measured physical activity at 12 months in women with prior gestational diabetes, though it improved self-efficacy, quality of life, and anxiety.
Effect estimate: Difference 0.95 mg (95% CI -0.46 to 2.37)
AIMS: Assess effectiveness of a hybrid intervention targeting physical activity in women with prior gestational diabetes. METHODS: Randomised controlled trial with parallel arms. 293 women (35.1 ± 5.1 years; 40% ethnic minority) recruited from two hospitals and randomised to routine care or hybrid lifestyle intervention comprising two group sessions and access to a mobile web app. Primary outcome was a change in objectively measured physical activity at 12 months. Secondary outcomes included self-efficacy for exercise, quality of life and anxiety and depression. Linear regression compared outcome measures between groups. RESULTS: 83% of intervention participants attended at least one group session, of who 66% registered to use the app. There was a non-significant increase in physical activity at 12 months (between-group difference of 0.95 mg 95% CI: -0.46 to 2.37), equivalent to approximately 500 steps per day. Intervention participants reported higher self-efficacy for exercise (0.54, 95% CI: 0.05 to 1.102; p = 0.029), lower anxiety (-0.91, 95% CI: -1.74 to -0.09; p = 0.031), and higher quality of life (0.05, 95% CI: 0.004 to 0.09; p = 0.032), compared to controls. CONCLUSIONS: The intervention improved confidence in exercise and quality of life. Further research is needed to improve participant engagement with physical activity interventions in multi-ethnic populations with a history of gestational diabetes.
Khunti et al. (Sun,) conducted a rct in History of gestational diabetes (n=293). Hybrid lifestyle intervention (group education and mHealth app) vs. Routine care was evaluated on Change in objectively measured physical activity at 12 months (Difference 0.95 mg, 95% CI -0.46 to 2.37). A hybrid group education and mHealth intervention yielded a non-significant increase in physical activity at 12 months versus routine care (difference 0.95 mg; 95% CI -0.46 to 2.37).
