"wearable activity trackers increased step counts on average by around 1800 steps per day, walking time by approximately 40 min per day, and moderate-to-vigorous physical activity (MVPA) by around 6 min per day." "effects were in favourable directions (ie, negative effects suggesting improvement in BMI, blood pressure, cholesterol, glycosylated haemoglobin, and waist circumference and bodyweight, and positive effects suggesting improvement in aerobic capacity)" "strong effects on step counts at 4–6 months (increase of 1127 [95% CI 710–1543] steps per day), [...smaller effect on] step counts up to 4 years (an increase of 494 [251–738] steps per day), [...another found] small but non-significant beneficial effects up to 1–2 years (BMI –0·21 kg/m², 95% CI –1·06 to 0·65).
