Brief Summary

The primary objective of this study is to examine between-group differences in changes of objectively measured MVPA levels (min/week) among a randomly selected sample of office employees who are physically inactive in Hong Kong.

Detailed Description

Regular participation in moderate-to-vigorous physical activity (MVPA) is related to decreased risk of morbidity and mortality. Among working populations, lack of MVPA may also be a risk factor for absenteeism and presenteeism. Both traditional workplace-based and web-based interventions have been suggested as being effective in promoting participation MVPA, health-related outcomes, and work-related productivity. However, several challenges limit their application in real world contexts. A 'blended' intervention approach combining the two intervention strategies is proposed to overcome these limitations. The proposed intervention aims to utilize the blended approach to increase participation in MVPA, health-related outcomes, and work productivity among inactive workers.

Methods: The study will comprise of a three group cluster randomized controlled trial (cluster-RCT), comprising a three-month actual intervention and a nine-month behavioral follow-up period. The three groups will be: a web-based intervention group, a blended intervention group combining the web-based components with face-to-face workshops, and a control group. Physically inactive office employees (N = 141) from will be recruited and randomly assigned to the three groups by cluster randomization. The intervention mapping (IM) framework will be used for selecting and applying effective health behavioural theories and behavioural change techniques (BCTs) to the development, implementation and assessment of the intervention, which will be personally tailored. The primary outcome variable will be objectively measured MVPA using an accelerometer. Secondary outcomes will consist of indices of health including adiposity, blood pressure, blood sugar, blood lipids, self-reported depression, anxiety, stress, and health-related quality of life, and work-related variables including absenteeism and presenteeism.

Study Groups

web-based intervention group

Except "Library", the participants in this group will also have access to the "Intervention" sub-section of the website. It will consist of six sessions delivered every two weeks following the same time schedule as the essay delivery in "Library".

Group Type: EXPERIMENTAL

web-based intervention

Intervention Type: BEHAVIORAL

A web-based intervention only referred to the use of internet without traditional face-to-face workshops and posters

blended intervention group

Except visiting "Library" and "Intervention" of the website, the participants in this group will also receive three face-to-face workshops (40 min per session) held at their workplaces.

Group Type: EXPERIMENTAL

blended intervention

Intervention Type: BEHAVIORAL

A blended intervention group combining the web-based components with face-to-face workshops and posters

Control group

The participants in the control group will have access to the "Library" sub-section of the website. General information of MVPA, health and work productivity will be provided with 18 short essays, which can be downloaded and printed out. The information will be factual and non-personally tailored.

Group Type: NO_INTERVENTION

No interventions assigned to this group
