Effects Of Home Environment On Physical Activities With Different Intensity In High School Students

Except school, home is the second largest place for students to encounter their daily lives, so physical and social environment of the family can contribute either positively or negatively to lifestyle behaviors of students. PURPOSE: This paper will quantitatively study the effects of home environment on different physical activities (PA) of high school students. METHODS: We conducted the research on 314 Chinese high school students and their parents. The home environment survey includes 39 items divided into four scales (PA availability,PA accessibility,Parental role modelling of PA,Parental policies to support PA).The PA of students divided into three different intensity (Sedentary Behavior, Light intensity,Moderate and Vigorous intensity) were measured by Actigraph GT3X+ device. The data was analyzed using the multiple linear regression. RESULTS: A one standard deviation (SD) increase in PA accessibility, mother role modelling of PA, mother policies to support PA was associated with a reduction in SB (minutes/week) by 65.44 (p < 0.05), 116.87 (p < 0.01) and 175.42 (p < 0.01) respectively. A one SD increase in PA accessibility, mother policies to support PA was associated with an increase in LPA (minutes/week) by 12.65 (p < 0.01) and 16.91 (p < 0.01) respectively; an increase MVPA (minutes/week) by 81.11 (p < 0.01) and 52.21 (p < 0.05) respectively. CONCLUSIONS: With the development of PA accessibility, the modeling and supportive policies of mother, the SB of high school students can be reduced significantly.And the PA accessibility and supportive policies of mother can evidently improve students’ LPA and MVPA.
