- Conditions
- Physically Well But Worried

- Behavioral: blended interventionBehavioral: web-based intervention
- Registration Number
- NCT04391270
- Lead Sponsor
- Hong Kong Baptist University
- 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.

Group Intervention Description blended intervention group blended intervention 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. web-based intervention group web-based intervention 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".
- Primary Outcome Measures
Name Time Method moderate-to-vigorous physical activity (MVPA) levels baseline, 13 weeks, 25 weeks 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
- Secondary Outcome Measures
Name Time Method changes of self-report MVPA levels (min/week) baseline, 13 weeks, 25 weeks To examine between-group differences in changes of self-reported MVPA levels (min/week) in different domains among the sample.
Body mass index (BMI, kg/m2) baseline, 13 weeks, 25 weeks Body mass index (BMI, kg/m2) will be calculated from weight and height.
Depression, anxiety and stress baseline, 13 weeks, 25 weeks Depression, anxiety and stress will be measured using the Chinese version of the Depression Anxiety Stress Scale (DASS-21)
Presenteeism baseline, 13 weeks, 25 weeks It will be assessed using presenteeism questions derived from the WHO's Heath and Work Performance Questionnaire (HPO).
Height in meters baseline, 13 weeks, 25 weeks Height will be measured to the nearest 0.1 cm using a stadiometer.
Weight in kilograms baseline, 13 weeks, 25 weeks 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.
Hemoglobin A1C (%) baseline, 13 weeks, 25 weeks Hemoglobin A1C will be measured using the Reflotron ® Plus system (Roche Diagnostics, F. Hoffmann-La Roche Ltd., Burgess Hill, UK).
High-density lipoprotein (mmol/L) baseline, 13 weeks, 25 weeks high-density lipoprotein will be measured using the Reflotron ® Plus system (Roche Diagnostics, F. Hoffmann-La Roche Ltd., Burgess Hill, UK).
Triglyceride (mmol/L) baseline, 13 weeks, 25 weeks Triglyceride will be measured using the Reflotron ® Plus system (Roche Diagnostics, F. Hoffmann-La Roche Ltd., Burgess Hill, UK).
Waist circumference (cm) baseline, 13 weeks, 25 weeks 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
%Body fat baseline, 13 weeks, 25 weeks %BF will be assessed by a Tanita TBF-410 Body Composition Analyzer (Tanita Corporation, Tokyo, Japan) using foot-to-foot bioelectrical impedance analysis (BIA).
Blood pressure (mmHg) baseline, 13 weeks, 25 weeks Blood pressure will be measured using the Omron M6 Compact (HEM-7000-E, Omron Healthcare Corporation, Kyoto, Japan) following standard measurement protocols.
