The primary purpose of the current study was to determine whether a text message intervention would increase break frequency and length of break from sitting, time spent standing, and time spent in light and moderate intensity physical activity in university students

Sedentary behaviour (SB) has been linked to many health problems (e.g., type 2 diabetes, heart disease). Interventions aimed at office workers, overweight and obese individuals have proven successful in reducing SB; however, no studies have examined university students.Text message-based interventions have succeeded to aid in smoking cessation and increase both physical activity and healthy eating, but have not been shown to reduce SB. Eighty-two university students were randomized into intervention (SB related text messages) or control (text messages unrelated to SB) groups. Participants received daily text messages and reported various SBs (i.e., breaks from sitting, standing, light and moderate intensity physical activity) at four time points (baseline, 2, 4 and 6 weeks).
