Brief 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

Condition or disease Intervention/treatment Phase
Sedentary Lifestyle Behavioral: text messages related to sedentary behaviour Not Applicable

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).

Primary Outcome Measures :
  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 ]
  5. Change in minutes spent in moderate intensity physical activity [ Time Frame: baseline, 2, 4, and 6 weeks ]

Secondary Outcome Measures :
  1. Change in self-efficacy for sedentary behaviour measured by percentage of confidence [ Time Frame: baseline, 2, 4, and 6 weeks ]
    purpose-built self-efficacy questionnaire used to rate how confident one feels in reducing sedentary behaviour
