Promoting Sustainable and Active Mobility Among Employees and Students (DiNaMo-active)

Impact of Physically Active Versus Passive Way to Work on Physical and Mental Aspects of Health in Members at Hannover Universities: an Observational Study

The aim of the study is to assess health data (heart rate variability, blood pressure, blood glucose, particulate matter pollution) and travel characteristics (length, duration and type of commute) on the way to and from work from members of the universities in Hannover (Germany).

Study Overview

• Status: Recruiting
• Conditions: Mobility on the Way to Work and Health-related Outcomes

Detailed Description

Active mobility, (i.e. moving around using the own physical strength) has positive sustainability effects. The physically active way to and from college is a great untapped resources for health promotion. The aim of this sub-project is to examine the way to university in order to assess its effect on individual health depending on the means of transport.

In order to determine the status quo and changes in mobility behavior the investigators will use movement trajectories using smartphone apps or inexpensive trackers in a larger cohort, as well as more specified health measures including overweight status, blood pressure, blood glucose concentration, lack of exercise, particulate matter and risk of accidents in a smaller sub-cohort.

By linking this data with the personal characteristics surveyed in other sub-projects, an evaluation of the individual health status and the expected health benefits depending on the route to work can be created. This represents the database for identifying certain groups of people or status groups who could particularly benefit from targeted promotion of an active commute.

Cohorts and Interventions

Group / Cohort
Long-term group; University members who use mainly one transport mode to get to the work place
Short-term group; University members who alternate their transport habits between physically active and passive commuting

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Heart rate variability (HRV)	HRV measured by a wearable activity tracker	24 hours on two separate days for the short-term subgroup, and 7 consecutive days for the long-term subgroup

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Blood glucose concentration	Intraindividual difference in blood glucose concentration between active and passive commuting as assessed with continuous blood glucose monitoring (Freestyle Libre 3)	24 hours on two separate days for the short-term subgroup
Work-Ability-Index	Interindividual difference between work ability as assessed with the Work-Ability-Index-Questionnaire. By adding up the points obtained from the questionnaire, scores can range from 7 to 49 points. The lower the score, the greater the discrepancy between the job demands placed on the respondent and their individual ability to cope with them.	Once at baseline for both study subgroups
24 hour blood pressure	Intraindividual difference in 24 hour arterial blood pressure between active and passive commuting as assessed with 24 hour systolic and diastolic blood pressure monitoring (Boso TM-2450)	24 hours on two separate days for the short-term subgroup
Daily moderate to vigorous physical activity (MVPA) duration	Interindividual difference in MVPA as assessed with a wearable activity tracker (Garmin Smartwatch Forerunner 55)	7 consecutive days for the long-term subgroup
Health-related quality of life	Interindividual difference between health-related quality of life as assessed with the Short Form 36 questionnaire. The possible score ranges from 0 to 100 points, with 0 points representing the greatest health impairment, while 100 points indicate no health impairment.	Once at baseline for both study subgroups
Particulate matter	Intraindividual difference in particulate matter concentration between active and passive commuting as assessed with a particulate matter measuring module	24 hours on two separate days for the short-term subgroup
