- In 2013/14, 57.6% of the adults aged 18 and over were considered overweight or obese based on their body mass index (BMI) (Fig. 7.4).
- Between 2003 and 2013/14 the proportion of adults who were overweight or obese increased by almost ten percent. The largest increase was seen among males but the increase was statistically significant among both males and females (Fig. 7.4).
The proportion of adults in Middlesex-London who were overweight or obese generally increased as age increased. The largest difference was most commonly seen between the age groups 20-44 and 45-64 (Fig. 7.5). In all adult age groups, nearly half the population or more was overweight or obese in 2013/14 (Fig. 7.5).
The Body Mass Index (BMI) is a ratio of weight to height (kg/m2) and is considered the most useful indicator of population health risk associated with both overweight and underweight.
Normal weight – BMI 18.5-24.9
Overweight – BMI 25.0-29.9
