Even though children imbibe their parents' long hours in front of the television, a new study has found that parents do not need to be physically active to encourage their children into exercise or game.
The study, conducted by Dr Russell Jago and colleagues in the Department of Exercise, Nutrition and Health Sciences at the University of Bristol, was funded by a grant from the British Heart Foundation.
AdvertisementIt found that higher parental TV viewing was associated with an increased risk of high levels of TV viewing for both boys and girls.
For girls, the relative risk of watching more than four hours of TV per day was 3.67 times higher if the girl's parent watched two-four hours of TV per day, when compared to girls who watched less than two hours of TV per day.
For boys, the relative risk of watching more than four hours of TV per day was 10.47 times higher if the boy's parent watched more than four hours of TV per day when compared to boys who watched less than two hours of TV per day.
There were no associations between the time that parents and children spend engaged in physical activity.
Among children and adolescents, physical activity has been associated with a lower BMI and a reduced risk of heart disease.
Regular physical activity is also known to help to prevent the development of type 2 diabetes, obesity and some cancers and is also associated with improved mental well-being.
"Physical activity has many positive effects on children's health while TV viewing has been associated with adverse health outcomes," Dr Jago, Senior Lecturer in the Department of Exercise, Nutrition and Health Sciences, said.
"Many children do not meet physical activity recommendations and exceed TV viewing guidelines.
"Our research suggests that parents do not need to be active for their children to be active.
"Parents should therefore look at ways in which they can help to facilitate physical activity for their children such as by encouraging walking to school or promoting outdoor free-play in safe areas close to home," he said.
Dr Mike Knapton, Associate Medical Director at the BHF, said:
"Parents and children rooted to the sofa watching over four hours of television each night paints a worrying picture of kids' daily habits.
"Ideally parents and children should lead an active lifestyle together but if this isn't possible then parents need to take charge and ensure a healthier way of life for the next generation.
"It's time to switch off the box and get the nation's kids moving again," he added.ear six children and their parents were recruited from 40 primary schools in Bristol to participate in the study to examine parents and children's physical activity patterns.
Parental and child physical activity and inactive time was assessed using accelerometers. These are small devices that provide accurate and reliable indices of physical activity among both children and adults.
The study, 'Parent and child physical activity and sedentary time: Do active parents foster active children?' has been published online in BMC Public Health.
