Overview• 2008/09 results

• Comparison between 2007/08 and 2008/09 results

• Obese prevalence –school charts

• School progress 2007/08 and 2008/09

• How we use these results- the way forward

• Summary

3


Data 2008/09• Participation rate 93% (target 85%; national 90%)

• R - 2908 children measured

• Yr 6 - 2497 children measured

• Definitions used for screening purposes

• Overweight above 85th centile of the UK1990 distribution

• Obese above 95th centile of the UK1990 distribution

4


Headline results• London had highest rate of obesity at SHA level

• In both R and Y6 Lewisham’s rate was similar to London and statistically significantly higher than England

• In R percentage of obese children rose from 10.6% (2007/08) to 12.0% (2008/09), but this is not statistically significant

• In Y6 percentage of obese children fell from 25.3% (2007/08) to 22.1% (2008/09), close to statistical significance

5


Comparative analysis• Need to remember:

• 2 years data not sufficient to determine trends

• Classes in 2007/08 and 2008/09 were different groups of children, so the analysis will not be comparing the same cohorts

• When comparing schools high proportion (percentages) do not necessarily mean large numbers if overall class size is small

Obesity prevalence -deprivation and ethnicity• Nationally strong link between deprivation and obesity prevalence in

children in both R and Y6

• In Lewisham link between deprivation and obesity observed but accounts for only about 3.3% of the variation (due to spread of deprivation in borough)

• Nationally obesity prevalence significantly higher in R and Y6 in the ethnic groups: Asian or Asian British, any other ethnic group and Black or Black British and significantly lower in R and Y6 in Chinese and White

• In Lewisham no statistically significant difference observed in prevalence of obesity between ethnic groups

Comparison of schools 2007/08 & 2008/09 • Of the 66 primary schools 42 recorded

reductions in Y6 obesity rates including all of the highest 25% in 2007/08

• There was no correlation between ranking of schools by Y6 obesity rates between 2007/08 and in 2008/09

How do we use these results?• There was no correlation between ranking of schools by Y6

obesity rates between 2007/08 and in 2008/09

• School ranking different if we look at proportions or number of children over healthy weight

- 8 schools with % over healthy weight in top 20 for both R and Y6

- 13 schools with n over healthy weight in top 20 for both R and Y6

But only 4 schools in both lists…

• Work with primary collaboratives?

24


Summary• High levels of childhood obesity in Lewisham,

12.0% of R and 22.1% of Y6 children obese 25.2% of R and 37.3% of Y6 children either overweight or

obese

• 2 years data not sufficient to determine trends

• When comparing schools, high proportion (percentages) do not necessarily mean large numbers if overall class size is small

• Sub group to meet to discuss how we use these results at school or collaborative level
