Study summary

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

Read the detailed description

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).

What researchers measure

Primary outcomes

  1. Change in length of break from sitting in minutes

    Time frame: baseline, 2, 4, and 6 weeks

  2. Change in frequency of break from sitting in minutes

    Time frame: baseline, 2, 4, and 6 weeks

  3. Change in minutes spent standing

    Time frame: baseline, 2, 4, and 6 weeks

  4. Change in minutes spent in light intensity physical activity

    Time frame: baseline, 2, 4, and 6 weeks

    Time frame: baseline, 2, 4, and 6 weeks

Secondary outcomes

  1. Change in self-efficacy for sedentary behaviour measured by percentage of confidence
