Trial Outcomes & Findings for The Impact of Real-time Feedback on Physical Activity Patterns in Flemish Employees (NCT NCT01432327)

NCT ID: NCT01432327

Last Updated: 2015-03-13

Results Overview

To account for differences in body size and composition, the 24-hour energy requirement (kcal/day) is expressed as a multiple of the basal metabolic rate per 24 hours by using the PAL value (PAL = total energy expenditure/basal metabolic rate). A desirable PAL includes the regular practice of physical activity at work or in spare time with an intensity and duration that will reduce the risk of becoming overweight and developing a variety of non-communicable chronic diseases usually associated as co-morbidities with obesity. This corresponds to PAL values of 1.75 and higher.

Participant Flow

August 2010 - May 2010: recruitement of employees. Method: flyering at Pharmacists, word of mouth, information session at companies in and around the region of Antwerp

Students and seniors were excluded from the study. Participants with an average Physical Activity Level above 1.71 times their resting metabolic rate were excluded from the trial

PRIMARY outcome

Timeframe: One year

Population: Intention to treat analysis was used and analyses data from all participants, including those who did not complete the study

SECONDARY outcome

Timeframe: One year

Minutes of physical activity. Activities can be classified as moderate-intensity, vigorous-intensity or very vigorous-intensity activities based upon the amount of energy used by the body while doing the activity.

SECONDARY outcome

Timeframe: One Year

According to The Stages of Motivational Readiness for Change Model (SOC), individuals move through a series of stages as they adopt and maintain a new habit(Prochaska \& DiClemente, 1983). Specifically, the stages include Precontemplation, Contemplation, Preparation, Action, and Maintenance.The relevant variables were assessed in a self-administered questionnaire.
