To ask the Scottish Executive what the rates of (a) overweight and (b) obesity have been amongst (i) children under 11 years, (ii) children aged between 11 and 18 and (iii) adults in each year since 1997.
The Scottish Executive does not collect information on obesity and overweight in the age bands specified. Information on rates of overweight and obesity amongst children is collected through the Child Health Surveillance Programmes for school-aged and pre-school aged children. Information is collected for school-aged children in Primary 1 (four to five years), Primary 7 (11 to 12 years) and S3 (14 to 15 years). Pre-school information is collected during the 39 to 42 month child health review when children are approximately three to three and a half years old. This information is provided below. These systems are not yet fully implemented across Scotland and so data is provided for the ten NHS board areas currently available.
The most reliable figures on adult obesity are published in the Scottish Health Survey. Surveys have been conducted in 1995, 1998 and 2003. The most recent figures from the 2003 Scottish Health Survey are provided at Table 3.
(i) Table 1a shows, for those ten NHS board areas available, the levels of overweight and obesity in children who have received a 39 to 42 month pre-school review (aged approximately three and a half years).

2. Includes overweight, obese and severely obese children (i.e. all children >= 85th centile).
Table 1b shows, for those NHS board areas available, the levels of overweight and obesity amongst those children who have received a Primary 1 and Primary 7 review (aged approximately four to five and 11 to 12 years respectively).

Notes relating to tables 1 and 2:
1. Data presented were extracted from the Child Health Surveillance Programmes – Pre School (CHSP-S) and School systems.
2. The CHSP-PS system was introduced in 1991 and now covers 10 NHS boards (Argyll and Clyde, Ayrshire and Arran, Borders, Dumfries and Galloway, Fife, Forth Valley, Greater Glasgow, Lanarkshire, Lothian and Tayside).
3. The CHSP-S system was introduced in 1995 and now covers 10 NHS Boards (Argyll and Clyde, Borders, Dumfries and Galloway, Fife, Forth Valley, Grampian, Lanarkshire, Lothian, Tayside and Western Isles). However, some have been introduced to the system fairly recently and therefore this analysis has concentrated on Argyll and Clyde, Borders, Fife, Lanarkshire, West Lothian NHS Trust and Tayside.
4. The surveillance systems routinely collect data on height and weight. These data can be used to calculate body mass index (BMI) and estimate the prevalence of over and under-nutrition in Scottish children.
5. BMI is a simple ratio of weight adjusted for height (weight(kg)/height(m)2) which provides an index of fatness or thinness. The prevalence of over and under-nutrition in a population of children relative to the UK 1990 population can be estimated by comparing the distribution of this ratio.
6. For the purposes of this analysis, those children who are on and above the 85th centile are defined as overweight. Those on or above the 95th centile are defined as obese.
(iii) Table 3 shows rates of overweight and obesity in Scottish adults based on data from the 2003 Scottish Health Survey.
