Nudges used to promote physical activity and to reduce sedentary behaviour in the workplace: Results of a scoping review.

Physical inactivity is one of the most important risk factors for non-communicable diseases. Workplace health promotion is therefore of growing interest to support an active day using nudges. The scoping review aims to (a) analyse how frequently nudges are applied in workplace health promotion to increase physical activity and/or reduce sedentary behaviour, and (b) characterise the nudges used. A systematic database search was conducted for the period 2009 to June 2020. According to predefined inclusion and exclusion criteria, studies promoting physical activity and/or reducing sedentary behaviour using nudges were included. Nudges were classified according to MINDSPACE and TIPPME. A study protocol was previously published. Of the 256 studies identified, 26 used nudges. Most studies were conducted in Europe (n = 12) and the USA (n = 8). N = 18 studies targeted physical activity and n = 8 studies targeted sedentary behaviour. In most studies promoting physical activity, prompts were given to climb stairs (n = 11). Interventions targeting sedentary behaviour were more diverse, using digital interventions or mixed approaches (n = 8). Although nudges can help increase physical activity and reduce sedentary behaviour, there are still gaps in terms of their effective and efficient use. There is a lack of long-term studies that analyse habituation and behavioural changes beyond the intervention period. In addition, the potential of digital and mixed approaches is not yet fully exploited. Further studies from low- and middle-income countries with different climates and working conditions are needed to investigate the feasibility of approaches and advance the fight against physical inactivity.

Using nudges to promote physical activity and to reduce sedentary behaviour in the workplace: a scoping review protocol.

INTRODUCTION: Physical inactivity and sedentary behaviour are associated with numerous health problems and increasing risks of premature morbidity and mortality. Workplace health promotion with a focus on increasing physical activity (PA) and reducing sedentary behaviour is of growing interest. The concept of choice architecture with the use of nudges is a promising approach to influence decision making regarding health behaviours. It can help to understand why people often fail to act in their best interest, to follow well-informed preferences or to achieve their set goals. Nudges, the way the choice is presented, can help to overcome these challenges by using the same habits, biases or boundaries to alter our decision-making in favour of the more preferred behaviour. Aims of the scoping review will be to analyse (a) to what extent the concept of choice architecture is used in workplace health promotion to promote PA and/or to reduce sedentary behaviour and (b) which instruments (nudges) are used to archive that. METHODS AND ANALYSES: Medline, PsychInfo, Web of Science and CINHAL will be searched from 2009 until June 2020. Applying a two-level screening process, title and abstracts will be screened according to a set of predetermined inclusion and exclusion criteria. Included articles will be screened a second time to determine the extent to which choice architecture has been used. Analyses for publication year, location, setting and target group will be provided. Interventions will be analysed presenting the instruments used, number of studies per instrument, combinations of instruments and alteration of the environment. Outcome measures and results will be reported as they occur. ETHICS AND DISSEMINATION: Due to the nature of the scoping review, ethical concerns are minimal. No patient data will be included. Results are published in peer-review journals.
