Introduction
SECONDARY, TYPE 2 DIABETES, CARDIOVASCULAR DISEASE
Sedentary behaviour in adults is linked with an increased risk of cardiovascular and all-cause mortality, type 2 diabetes, cardiovascular disease, musculoskeletal health issues, and poor mental health [Contact centres are workplaces where employees handle a high volume of incoming and/or outgoing calls for various purposes such as sales and customer service [To date, there are no published systematic reviews assessing the effectiveness of sedentary behaviour interventions in contact centres and very few interventions have been developed and evaluated in this setting [Stand Up for Health (SUH) is a complex intervention that aims to reduce sedentary behaviour in contact centres and takes into account the context and needs of employees and employers. The SUH programme was developed through a rigorous process using the 6SQuID intervention development framework, as discussed in an earlier paper [Step 5 of the 6SquID framework involves testing and adaptation of the intervention [The aim of this study was to test the acceptability and feasibility of implementing the SUH intervention in UK contact centres [Provide estimates of the variability of primary outcome (sedentary behaviour in the workplace) and secondary outcomes to inform sample size calculations for future studiesExplore experiences and acceptability of the SUH intervention activities and implementation processesUnderstand whether SUH activities worked as intended and investigate any unintended consequences of the interventionIdentify differences in delivery of the intervention, between different contact centres and the reasons for these.
