SAP is an open access publisherOBJECTIVES: The multicultural study aims at examining Physical Activity Change of English, French and Chinese speaking immigrants in Ottawa and Gatineau, Canada, and identifying demographic factors that correlate with the change and impact the change. METHODS: 810 immigrants of three language sub-groups were recruited by purposive-sampling. Using self-reports, respondents answered questions regarding Physical Activity Change and Demography in Multicultural Lifestyle Change Questionnaire of English, French or Chinese version. Data were analyzed statistically in percentage, correlation, regression and factor analysis. RESULTS: Immigrants of different gender, language and category sub-groups exhibited different rates in Physical Activity Change, and different language sub-groups displayed different Physical Exercise Items rates after immigration, but no statistical difference between the rates. Physical Activity Change (Physical Activity Behavior Change + Physical Activity Belief Change) was negatively correlated with Gender, Category of Immigration, Employment Status and Primary Occupation. Physical Activity Behavior Change was negatively correlated with Age, Gender, Category of Immigration, Employment Status and Primary Occupation. Age, Gender, Category of Immigration and Employment Status significantly impacted Physical Activity Change. Mother Tongue, Age, Gender, Category of Immigration and Employment Status significantly impacted Physical Activity Behavior Change. Two factors (factor one: physical activity behavior change factor and factor two: physical activity belief change factor) influenced significantly Physical Activity Change. Factor one exposed more significant effect than factor two. CONCLUSIONS: Different immigrant sub-groups experienced different Physical Activity Change and three language sub-groups presented different physical activity patterns after immigration. Age, Gender, Category of Immigration, Employment Status and Primary Occupation were main factors impacting significantly Physical Activity Change. Mother Tongue was an important factor influencing significantly Physical Activity Behavior Change. Culture and acculturation were relating contributing factors. Data may provide evidence and implication for physical exercising policy-making and policy-revising in Canada
