This study will be investigating whether a theory-based physical activity intervention can maintain/improve moderate to vigorous intensity physical activity measured via accelerometry of new parents over the eight months of having a child compared to a control group of new parents.
Hypothesis: The theory-based condition will change salient underlying motives (theory of planned behaviour constructs) for physical activity. Health-related fitness and quality of life will also be higher for this condition in comparison to the control condition. (Note: improvements in both groups of mothers may occur due to recovery from pregnancy, but our hypotheses will still hold). All outcomes will remain significantly higher at eight months in the theory-based condition compared to the standard condition

|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||152 participants|
|Intervention Model:||Parallel Assignment|
|Official Title:||First-time Parents Physical Activity Intervention|
|Actual Study Start Date :||March 2014|
|Actual Primary Completion Date :||December 2018|
|Actual Study Completion Date :||December 2018|
Experimental: Theory-based group
The theory-based intervention group will receive strategies based on the Theory of Planned Behaviour to help increase physical activity among couples. Parents will receive materials on how to work together.
Behavioral: Theory-based group
Workbooks and mini-counselling sessions will be provided to participants in this group.
No Intervention: Information group
The information group will serve as the control group and will receive informational materials on the benefits of physical activity.
- Change in Objective and Self-report Physical activity [ Time Frame: Baseline, 6 weeks, 3.5 months, and 6 months ]Physical activity will be measured objectively for 7 consecutive days using the wGT3X-BT Activity Monitor combined with self-report of PA using the Godin Leisure-Time Exercise Questionnaire (LSI) at each time period.
- Demographic information [ Time Frame: Baseline ]Basic information on gender, age, ethnicity, income, education level will be gathered.
- Health measures [ Time Frame: Baseline and 6 months ]Information on leave status, child care status, diet, sleep (Pittsburgh sleep quality index) and breastfeeding status, smoking, alcohol consumption will be included in this assessment.
- Motivation for physical activity [ Time Frame: Baseline, 6 weeks, 3.5 months, 6 months ]Motivation will be measured using the constructs of the theory of planned behaviour. Items will measure all components of the model (affective attitude, instrumental attitude, injunctive norm, descriptive norm, perceived control, planning) including behavioural, normative, and control beliefs.
- Health related quality of life/psychosocial distress [ Time Frame: Baseline, 6 weeks, 3.5 months, 6 months ]This will be assessed with parents using the Satisfaction with Life Scale. In addition, we will assess depressive and anxiety symptoms with the Hospital Anxiety and Depression Scale (HADS), which also has sound reliability and validity compared to similar instruments.
- Health related fitness [ Time Frame: Baseline and 6 months ]We will assess the key components of health-related physical fitness including body composition, aerobic fitness and musculoskeletal fitness which are valid for males and females.
