Prevalence and trends in child PA and SB Flashcards
What are the UK recommendations for PA and SB for children <5
those capable of walking should do at least 3 hours of PA, spread evenly through the day
should minamise the amount of time spent sedentary for prolonged periods
what are the UK recommendations for PA and SB for children aged 5-18
engage in at least 60 mins MVPA, up to several hours per day
vigorous intensity activity, including that which strengthens muscle, should be incorporated at least 3 times a week
minimise time spent sedentary for extended periods
Give some findings of note from the millennium cohort study
what is the strength of this study
50% or 7year olds were meeting the PA recommendations
generally more boys than girls met them
lowest ethnic group meeting guidelines by % was south Asian
Was good because it was accelerometry data and so was objective
what is the trend in the annual decline in levels of PA
rate of decline was greater for the last decade than for the previous two
a greater increase in the rate of decline was seen for girls
Give some findings of note from the International Children’s Accelerometry Database
at 9-7 boys were slightly more active than girls
as they get older, the difference between them increases
overall level of activity decreases for both sexes with age
a very small portion of children met guidelines on everyday measured
Give some encouraging findings from the international study of childhood obesity, lifestyle and the environment
despite not meeting the guidelines, most children did enough PA to be very close
so overall, picture not as bad as data of % of children meeting the guideline would suggest
what are the trends seen for PE time and outdoor play in the UK
PE time reducing
also no longer compulsory to do 2hrs per week
37% decline in ourdoor play between 1997 and 2003
decline in % of children doing some activity
increase in % doing no activity
Give some possible reasons for the decline in PA and the increase in SB
decline in active transport
changing leisure activities, more are now screen based
change in parental attitudes towards PA
labour saving devices
less safe for children to go out
society discourages outdoor play
what trends are seen in childhood SB
% of time spent sedentary increases with age
throughout childhood, girls are more sedentary that boys
children are more likely to spend a large amount of time being sedentary at the weekend
extreme levels of SB (>6hrs) is more prevelent in boys
How has children’s exposure to screen based technologies changed with time
TV consistent
computers and game consoles in slight decline
tablet computer use/ownership rapidly increasing
(% of children owning a tablet increases with age)
Smartphone ownership is also increasing
self-reported media exposure steadily increasing between 1960-2000
rate of increase much greater after 2000
when children’s PA and SB was compared to that of children in a traditional community, what was found
traditional children had more overall activity, particually at high and moderate intensities
but was no real difference in SB, bc children were still at school for long periods etc
why has it been said that surveillence of PA in the UK is flawed?
original questionnaire used until 2008 was flawed
found to over-estimate MVPA when compared to accelerometer data
give three factors which can explain why child travel behaviour has changed in recent years
development of a car orientated environment
increase in number of mothers at work
change in attitude towards children’s independent mobility
what is the difference in terms of definition and in terms of energy expenditure between free play and organised play
free play = just going outside to play
organised play = clubs, football practice etc
organised play generally doesn’t have as much overall energy expenditure because children are driven there
what’s the association between car ownership and amount of walking a child does
more car ownership = less child walking
car use is method of transport for over 50% of child journeys
