Objectives-To trace patterns of health and health behaviour in those with ancestry in the Indian subcontinent (British Asians) compared with the general population of their age (1) in the younger generation age 14-15 mainly born in the UK and (2) in the older mainly migrant generation. Design-Cross sectional random sample surveys of two age groups in Glasgow. (J Epidemiol Community Health 1998;52:558-563) The health behaviour of British Asians (those with ancestry in the Indian subcontinent) is generally thought to be advantageous for health. Even allowing for variations within heterogeneous British Asian communities, the general picture is favourable whether in regard to smoking, drinking or diet, 1 2 and only exercise levels seem to be unfavourable.

3However, the health of these communities does not seem to have benefited as much as it should from their generally exemplary behaviour. Low levels of lung cancer are not matched by low levels of heart disease, and respiratory health too does not seem to show the advantages that might be expected from such low smoking levels, particularly among women. It is true that while migrant women of South Asian descent show a number of health disadvantages, migrant men show a number of advantages in relation to the majority of population, and this is evident both in studies of mortality, 4 5 and morbidity. 6 The male advantage, however, tends to be put down to positive selection for health at the time of migration, though this has been assumed rather than tested.It would be tempting, in this situation, for the younger generation of British Asians to conclude that good behaviour does not pay; and certainly the health record does not provide much counterweight to the powerful pressures drawing them towards conformity with the norms of their peers in the majority population. Although earlier studies have shown health behaviour in young British Asians that continues to diVer from the patterns of the majority population in broadly similar ways to that of their parents, 7 it has not been possible without more accurate comparisons to assess how far these diVerences are eroding. Meanwhile little is known of the general health of young British Asians, or, consequently, of whether their health is as unrelated to their health behaviour as it is in the migrant generation.An opportunity to explore these issues is provided by a school-based study of 14-15 year olds from the British Asian and general populations, nearly all born in the UK, which asked similar questions on health and health behaviour to a community survey of migrant South Asians and the general population aged 30-40, both studies taking place in the same city. This report considers the following questions:(1) What pattern of health advantages and disadvantages do young British Asians show compared with the majority population?(2) What patterns of health behaviour do they show compared with the majority population, at the age when addictive behaviours tend to be tried out?
