Brief Summary

This project will assess the feasibility of a 12-week physical activity program developed specifically for females exposed to a known occupational carcinogen - shiftwork. Physical activity has been shown to decrease cancer risk, but the investigators research has found that female shift workers face unique barriers to participating in physical activity. This project will use a combination of telephone-based behavioural counseling sessions with a physical activity coach, and innovative web-based physical activity tracking software using a Fitbit and website or smartphone app to address commonly reported barriers to physical activity in female shift workers.

Outcome Measures

Primary Outcomes (1)

• Feasibility: A composite outcome of overall feasibility will be assessed as the primary outcome.

  We will consider the intervention to be feasible if all of the following conditions are met: 1) Achieve a recruitment goal of 20 participants in three months; 2) Achieve a retention rate of 80% of enrolled participants; 3) Achieve \> 80% adherence to behavioral counseling sessions; and 4) \>80% of participants rank their satisfaction with the study as "Satisfied" (4) or "Very Satisfied" (5) on a five-point Likert scale.

  Baseline, 12 weeks

Secondary Outcomes (4)

• Physical Activity (MET hours per week)

• Sedentary Time

• Sleep quantity and quality

Exercise

EXPERIMENTAL

The behaviour change intervention to promote an increase in moderate-vigorous physical activity (to meet the cancer prevention guidelines of 150 min/week) will be guided by the Health Action Process Approach (HAPA) model. This model aims to promote behaviour change through increasing self-efficacy for intention, planning and maintenance of physical activity. As a compliment to the behavioural counseling sessions, participants will be asked to track their physical activity using the FitBit, a wrist-worn activity monitor (www.fitbit.com) which monitors step counts, distance covered, and active minutes and also tracks sleep. The FitBit synchronizes wirelessly to the participants' computer and/or smartphones, thus minimizing the need for daily data entry tracking by participants.
