  • moderate-to-vigorous physical activity (MVPA) levels

    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

    baseline, 13 weeks, 25 weeks

Secondary Outcomes (12)

  • changes of self-report MVPA levels (min/week)

    baseline, 13 weeks, 25 weeks

  • Height in meters

    baseline, 13 weeks, 25 weeks

  • Weight in kilograms

    baseline, 13 weeks, 25 weeks

  • Body mass index (BMI, kg/m2)

    baseline, 13 weeks, 25 weeks

  • Waist circumference (cm)

  • +7 more secondary outcomes

Study Arms (3)

web-based intervention group

EXPERIMENTAL

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".

Behavioral: web-based intervention

blended intervention group

EXPERIMENTAL

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.

Behavioral: blended intervention

Control group

NO INTERVENTION

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.

Interventions

blended interventionBEHAVIORAL

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