 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.
