Measurement of the Body Mass Index (BMI) of Primary 1 pupils has been undertaken in North and South Lanarkshire since  2001/2; in Renfrewshire since 2006/7; and, in Inverclyde, Glasgow, West Dunbartonshire and East Renfrewshire since 2011/12.  In recent years, the highest level of obesity among Primary 1 children in the region has been found in Inverclyde, and the lowest in East Renfrewshire. Future data collection and analysis will cast more light on longer term trends.


Children who are in their first year of primary school (P1 pupils usually aged 4-5 years old) have their height and weight measured and results recorded on a national  child health school system. These measurements can be used to estimate the prevalence of overweight and obesity in children based on a reference population representing the normal pattern of growth for healthy children (UK 1990 growth reference standards).  A child is classified as overweight if his/her BMI is in the highest ten percent of values for boys and girls of this age and obese if his/her BMI is in the highest five per cent.  A child with a BMI  that is in the top two percent is classified as severely obese. Historically, within NHS Greater Glasgow & Clyde, data have only been collected in Renfrewshire, but the entire Board area has been covered since 2011/12.

Figures from elsewhere in Scotland can be accessed here.

Obesity has also been included in some of the reports from the Growing Up in Scotland Study - section 6.5.

Information about diet and physical activity can be found in the children's lifestyle section and the adult's lifestyle section of this site.
