Merton

• One in five children in Reception year is overweight or obese

• One on three children in Year 6 is overweight or obese

So what?• Children experience psychological effects: teasing and discrimination by

peers; low self-esteem; anxiety and depression

• Childhood obesity is associated with a higher chance of premature death and disability in adulthood from:– cardiovascular diseases – diabetes– musculoskeletal disorders– certain types of cancer (e.g. breast and colon)

• Many overweight children will become overweight adults (and parents!)

Determinants of Obesity

Source: http://www.cdc.gov/pcd/issues/2009/jul/09_0013.htm

In words:• Childhood obesity is mainly associated with unhealthy eating and low

levels of physical activity, but the problem is linked not only to children's behaviour but also, increasingly, to social and economic development and policies in the areas of agriculture, transport, urban planning, the environment, food processing, distribution and marketing, as well as education

• The problem is societal and therefore it demands a population-based multi sectoral, multi-disciplinary, and culturally relevant approach.

• Children and adolescents cannot choose the environment in which they live or the food they eat. They also have a limited ability to understand the long-term consequences of their behaviour.

Background• National Child Measurement Programme (NCMP) is a

national programme to measure the weight of children in Reception and Year 6 in English state schools

• Aim: to monitor overweight and obesity to guide effective policy making to reduce obesity

• Parents receive individual feedback about measurement• Measure used = BMI, adjusted for normal growth variation

between Reception and Year 6, and sex.

NCMP results – action

• National data for monitoring and policy

• Local feedback of measurements• to parents (NHS community services)• to headmasters (NHS Public Health)• referrals to treatment programme ‘Alive n Kicking’

What is Alive ‘N’ Kicking?• Specialist healthy weight programme for

children aged 4-19

• Physical activity sessions for children

• Interactive nutrition workshops for parents, focusing on practical ways to improve the family diet.

Group programmes for 4-6yrs, 7-11yrs, 12-15yrs and 16-19yrs, with capacity of 20 participants per group

Results so far March 2012...

• 70% of graduates reduced their BMI

• 84% of graduates reduced their waist circumference

• Average weight loss was -1.05 kg

Training: 88 local candidates trained including EY staff and Health

Completers:Jul ’09 - Mar ‘11 = 105 / yrApr’11 – June ‘12 = 161 / yr53% increase in completers

Referrals: on average 26 referrals per month

Local feedback to schools

• National guidelines: detailed school data may not be shared with schools

• We use a national but ‘Mertonised’ tool for feedback about the 2010-2011 results to Merton headmasters

• The letter will include information about local support to help children and their families to keep a healthy weight

• Participation rate Merton - England: – 87.1% Reception = lower than nationally– 91.2 % Year 6 = same as nationally
