Childhood Obesity in Wiltshire NCMP Analysis Introduction The National Child Measurement Programme (NCMP), first established in 2006, is an annual programme which measures the height and weight of children in Reception Year, (aged 4-5 years) and Year 6 (aged 10-11 years) within state maintained schools across England in order to create a body max index for the children. It is an important element of the Government s work programme to tackle childhood obesity. The NCMP data set helps to inform professional understanding of weight issues in children and provides a useful vehicle for engaging with children and families about healthy lifestyles. National data has been published for 20113/14. A single year provides robust data to make comparisons outside of Wiltshire. A number of bar graphs depicting the NCMP data in Wiltshire the South West and England from 2006/07 to 2013/14 can be found in the NCMP Wiltshire datasheet. To create robust results within Wiltshire three financial years of NCMP data has been aggregated. This reduces the impact of annual variation seen by measuring a single year at smaller geographies within Wiltshire. A number of outputs have been provided in this document based on data from 2011/12, 2012/13 and 2013/14, these are; gender, deprivation, Community Area and Children s Centre in order to identify any geographical patterns. Confidence intervals have been used to calculate significance from the Wiltshire average but have not been displayed in the graphs as error bars. Instead the colours red, amber and green have been used to donate if a figure is above, similar to, or below the Wiltshire average. Key facts Girls are less likely to be obese or obese and overweight than the Wiltshire average. Children in the most deprived quintile are more likely to be obese or obese or overweight than the Wiltshire average. Children living in Trowbridge Community Area are more likely to be obese or obese or overweight than the Wiltshire average. The area surrounding Salisbury Little Folly Children Centre has more obese or obese or overweight children than the Wiltshire average.
Results Gender Figure 1 and 2 indicate that girls are less likely to be obese than the Wiltshire average in reception year and year 6. Boys are more likely to obese in year 6 than the Wiltshire average. Figure 1 Figure 2
Figure 3 indicates that girls are less likely to be obese or overweight in reception year. However, figure 4 shows no statistically significant difference for girls or boys when looking at the percentages of obese or overweight children in year 6. Figure 3 Figure 4
Deprivation We have used the indices of multiple deprivation data to allocate a child based on where they live to a deprivation quintile within Wiltshire. Figures 5 and 6 show that for both reception and year 6 the most deprived quintile has a significantly higher percentage of obese children than the Wiltshire average. The figures also show that the percentage of obese children in the least deprived quintile for both reception and year 6 is significantly below the Wiltshire average. Figure 5 Figure 6
Figures 7 and 8 show that for both reception and year 6 the most deprived quintile has a significantly higher percentage of obese or overweight children than the Wiltshire average. The figures also show that the percentage of obese or overweight children in the least deprived quintile for both reception and year 6 is significantly below the Wiltshire average. Figure 7 Figure 8
Community Area Wiltshire has been divided into 20 community areas. Providing data at this geography enables local communities to take action. In reception Marlborough has a significantly lower percentage of obese children than the Wiltshire average (figure 9). In year 6 Marlborough, Bradford on Avon and Malmesbury have significantly lower percentages of obese children than the Wiltshire average (figure 10). Trowbridge has a significantly higher percentage of obese year 6 children than the Wiltshire average. Figure 9 Figure 10
In reception Marlborough and Pewsey have a significantly lower percentage of obese or overweight children than the Wiltshire average (figure 11). Melksham and Tidworth have a significantly higher percentage of obese or overweight children than the Wiltshire average. In year 6 Malmesbury and Bradford on Avon have significantly lower percentages of obese or overweight children than the Wiltshire average (figure 12). Trowbridge has a significantly higher percentage of obese or overweight year 6 children than the Wiltshire average. Two maps have been provided depicting the obese or overweight percentages.

Children Centres There are 30 Children Centres in Wiltshire. Providing data by Children Centres based on where a child lives allows them to accurately act to reduce obesity. Marlborough Corner House and Malmesbury Children Centre have significantly lower percentages of obese reception children (figure 13). Trowbridge Longfield, Salisbury Little Folly and Tidworth Windmill Hill Children Centre have significantly higher percentages of obese reception children. Marlborough Corner House has a significantly lower percentage of obese or overweight reception children (figure 14). Melksham Kings Park, Tidworth Windmill Hill and Trowbridge Longfield Children Centre have significantly higher percentages of obese or overweight reception children. Figure 13 Figure 14
Conclusion December 14 The local analysis highlights a number of important issues. Significant Inequalities exist between genders, deprivation quintiles, Community Areas and Children Centre areas. Girls are less likely to be obese than the Wiltshire average in reception year and year 6 (figure 1 and 2). They are also less likely to be obese or overweight in reception year (figure 3). Boys are more likely to be obese in year 6 than the Wiltshire average. The most deprived quintile for both reception and year 6 has significantly higher percentages of obese or obese or overweight children than the Wiltshire average (figure 5, 6, 7 and 8). The children in the least deprived quintile for both reception and year 6 is significantly below the Wiltshire average. Trowbridge has a significantly higher percentage of obese and obese or overweight year 6 children than the Wiltshire average. Melksham and Tidworth have a significantly higher percentage of obese or overweight children than the Wiltshire average. Trowbridge Longfield, Salisbury Little Folly and Tidworth Windmill Hill Children Centre have significantly higher percentages of obese reception children. Melksham Kings Park, Tidworth Windmill Hill and Trowbridge Longfield Children Centre have significantly higher percentages of obese or overweight reception children.
