  1. Interrelationships Black Obesity Caribbean S. Asian ethnicity Diabetes Cardiovascular disease Ethnic differences in obesity and overweight among British children Dr Sonia Saxena*, Dr Gareth Ambler#, Professor Tim J Cole†, Professor Azeem Majeed* *Dept. of Primary Care & Social Medicine, Imperial College London, †Dept of Epidemiology and Biostatistics Institute of Child Health, #University College London Hospital NHS Trust Aims: To determine the proportion of children and young adults who are obese or overweight within different ethnic and socio-economic groups. a Design: Secondary analysis of cross-sectional survey data from the1999 Health Survey for England Results: 23% of children (n=1311) were overweight of whom 6% (n=358) were obese. More girls than boys were overweight (24% vs. 22% respectively P=0.03). Afro-Caribbean girls were more likely to be overweight(odds ratio 1.73, 95% confidence interval 1.29 to 2.33) and Afro-Caribbean and Pakistani girls were more likely to be obese than girls in the general population (ORs 2.74, 1.74 to 4.31 and 1.71, 1.06 to 2.76 respectively). c Indian and Pakistani boys were more likely to be overweight (ORs 1.55, 1.12 to 2.17 and 1.36, 1.01 to 1.83 respectively). c There were no significant differences in the prevalence of obese and overweight children from different social classes. Subjects: 5689 children and young adults aged 2 to 20 years living in private households in England b Main outcome measures: Prevalence of overweight and obese girls and boys based on age and sex specific BMI cut off points, as defined by the International Obesity Task Force b • Key messages and further work: • Ethnicity is a strong determinant of obesity in children • British Afro-Caribbean & Pakistani girls are more likely to be obese and Indian & Pakistani boys more likely to be overweight than the general population • Social class differences are not directly associated with obesity in British children • Future studies should address the possible mechanisms for the association between ethnicity and obesity, for example differences in dietary and exercise patterns a Social class of head of household : I&II, IIIn, IIIm, IV&V. Ethnicity assigned by head of household using Census ’91 categories. See www.doh.gov.uk/HSE_99 bEstablishing a standard definition for child overweight and obesity world-wide: international survey.
