About this study

Official title: A Blended Intervention to Promote Physical Activity, Health and Work Productivity Among Office Employees Using Intervention Mapping: A Study Protocol for a Randomized Controlled Trial

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.

Read the 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 in NCT04391270
Study groupRoleWhat they receive
web-based intervention groupExperimentalExcept "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".
Receives: Behavioral: web-based intervention
blended intervention groupExperimentalExcept 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.
Receives: Behavioral: blended intervention
Control groupNo interventionThe 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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

    Measured: baseline, 13 weeks, 25 weeks

Secondary outcomes (12)
  1. changes of self-report MVPA levels (min/week)

    To examine between-group differences in changes of self-reported MVPA levels (min/week) in different domains among the sample.

    Measured: baseline, 13 weeks, 25 weeks

  2. Height in meters

    Height will be measured to the nearest 0.1 cm using a stadiometer.

    Measured: baseline, 13 weeks, 25 weeks

  3. Weight in kilograms

    Weight will be measured to the nearest 0.1 kg on a calibrated digital balance scale (Seca, max. 200 kg, Germany) with the participants wearing lightweight clothing and no shoes.

    Measured: baseline, 13 weeks, 25 weeks

  4. Body mass index (BMI, kg/m2)

    Body mass index (BMI, kg/m2) will be calculated from weight and height.

    Measured: baseline, 13 weeks, 25 weeks

  5. Waist circumference (cm)

    Waist circumference (cm) will be measured midway between the lowest rib margin and the top of the iliac crest at the end of gentle expiration

    Measured: baseline, 13 weeks, 25 weeks

  6. %Body fat

    %BF will be assessed by a Tanita TBF-410 Body Composition Analyzer (Tanita Corporation, Tokyo, Japan) using foot-to-foot bioelectrical impedance analysis (BIA).

    Measured: baseline, 13 weeks, 25 weeks

  7. Blood pressure (mmHg)

    Blood pressure will be measured using the Omron M6 Compact (HEM-7000-E, Omron Healthcare Corporation, Kyoto, Japan) following standard measurement protocols.

    Measured: baseline, 13 weeks, 25 weeks

  8. Hemoglobin A1C (%)

    Hemoglobin A1C will be measured using the Reflotron ® Plus system (Roche Diagnostics, F. Hoffmann-La Roche Ltd., Burgess Hill, UK).

    Measured: baseline, 13 weeks, 25 weeks

  9. Depression, anxiety and stress

    Depression, anxiety and stress will be measured using the Chinese version of the Depression Anxiety Stress Scale (DASS-21)

    Measured: baseline, 13 weeks, 25 weeks

  10. Presenteeism

    It will be assessed using presenteeism questions derived from the WHO's Heath and Work Performance Questionnaire (HPO).

    Measured: baseline, 13 weeks, 25 weeks

  11. High-density lipoprotein (mmol/L)

    high-density lipoprotein will be measured using the Reflotron ® Plus system (Roche Diagnostics, F. Hoffmann-La Roche Ltd., Burgess Hill, UK).

    Measured: baseline, 13 weeks, 25 weeks

  12. Triglyceride (mmol/L)

    Triglyceride will be measured using the Reflotron ® Plus system (Roche Diagnostics, F. Hoffmann-La Roche Ltd., Burgess Hill, UK).

    Measured: baseline, 13 weeks, 25 weeks
