Study On Family Members' PA Of 7?9-Year-Old Children And Their Influence On Healthy Fitness

ObjectiveIn this study,we studied the effects of parents' physical activity level(PA)and health fitness status on children's PA level and healthy body fitness level in different educational backgrounds and economic status families.MethodsA total of 108 subjects were selected from 36 households in Beijing(aged between 30 and 39 years old and their children aged between 7 and 9 years).Parents were tested for PA levels by wearing a 1-week accelerometer,and the child conducted a PA-level survey by completing the revised PAQ-A Chinese version of the questionnaire.Parents and children are healthy body fitness indicators of the test.The correlation analysis of the test results was carried out.Results(1)The average score of MVPA was 42.95 ± 7.84 min for father and 41.75 ± 3.72 min for mother(P>0.05),and the score of MVPA was 2.83 ± 0.60 for child.(2)The average duration of MVPA in high-income families was longer than that in low-income families(44.45 ± 6.09min,40.24 ± 5.46min.P<0.05).(3)The PA score of the PA active family was 3.02 ± 0.53,the BMI was 15.63 ±1.95kg/m2,the PA score for the PA family was 2.61 ± 0.58 and the BMI was 17.77 ±3.67kg/m2.Significant difference(P<0.05);(4)There was a positive correlation between father and child and body fat percentage and vital capacity,and the correlation coefficients were 0.422 and 0.409 respectively(P<0.05).There was a positive correlation between mother and child in the level of vital capacity(r(R =-0.301,P>0.05),and there was a negative correlation(r =-0.301,P>0.05)at 50*8 run back and forth.(R =-0.346,P<0.05).The negative correlation between the MVPA score and the 50*8 run back and forth(r =-0.346,P<0.05)(R = 0.406,P<0.05).There was a positive correlation between the time of male mother's MVPA and the flexion of the sitting body(r = 0.404(P<0.05),and there was a positive correlation between the time of MVPA and the percentage of body fat,P<0.05).Conclusion(1)MVPA in children aged 7-9 years had no significant correlation with MVPA.(2)The height,weight,body fat ratio and vital capacity of children aged 7-9 years were significantly influenced by their fathers,and the height and vital capacity were affected by their mothers.(3)The cardio respiratory endurance and flexibility of the children were affected by the mother to some extent.
