Evaluation eines online-basierten Motivations- und Dokumentationsprogramms zur Gewichtsreduktion

Abstract

Evaluation of an online-based motivation and documentation programme for weight loss. Results of a randomised controlled study Objectives: The objective of the study was to examine whether the use of an online-based motivation and documentation programme leads to weight loss within one year in overweight employees, compared to a control group. Methods: This is a randomised controlled trial conducted from 2018 to 2019 in Ludwigshafen. Members of the intervention and control groups received a measuring tape and a pedometer at the start of the study. Subjects in the intervention group also received access to a website with a motivational programme. At study inclusion, after 6 and 12 months, all study participants received a questionnaire regarding subjective assessment of fitness status, dietary behaviour, and evaluation of the website and pedometer. All study participants also received a monthly newsletter with information on health topics. Results: A total of 279 subjects participated in the study, with information on the primary study endpoint available for 165 (59 %) after 12 months. After 12 months, weight was reduced by 0.73 kg and 1.16 kg in the intervention and control group respectively (mean difference: 0.43 kg; 95% CI: –1.06 kg to 1.92 kg; p = 0.571). Abdominal circumference was reduced by 1.27 cm and 1.74 cm in the intervention and control group respectively (mean difference: 0.47 cm; 95 % CI: –0.96 cm to 1.91 cm; p = 0.521). Regarding subjective assessment of physical activity and dietary behaviour, there were also no statistically significant differences between the groups. Of those who participated in the final survey and, in relation to the website, logged in at least once, the website and pedometer were predominantly rated positively. Conclusions: The study did not show a weight-reducing effect of intervention through the online app. Further studies on digital applications (apps) with adapted or additional functions are needed to evaluate whether they can be a component on the path to desired permanent weight loss in the future.
