Trends in growth and obesity in ethnic groups in Britain

AIM: To estimate trends in growth for 5 to 11 year old ethnic minority and inner city children and comparative representative samples from 1983 to 1994. DESIGN: Mixed longitudinal. SUBJECTS: At each of six surveys, more than 2000 inner city white, 1500 Urdu or Punjabi speaking, 5000 English representative white, 3000 Scottish representative white, and around 1000 Afro-Caribbean, 500 falling to 300 Gujarati speaking, and 260 increasing to 300 other Indian children. MAIN OUTCOME MEASUREMENTS: Height, weight for height, and triceps skinfold thickness. RESULTS: Height increased in all inner city groups by approximately 1.5 cm, but group differences were maintained. Trends in triceps skinfold varied, but increased by 4-12% in Indian subcontinent girls. Weight for height increased generally. Inner city white children showed conflicting trends in weight for height and fatness. CONCLUSIONS: Afro-Caribbean children are maintaining their tall, slim build, but other groups emphasise the diversity of obesity patterns in a multi-ethnic society, with a predominant trend towards greater obesity. Monitoring of these groups should continue.
