There may be differences by ethnic group in behaviour in relation to the options for healthcare.
Many factors associated with obesity at age 5 are also similar across ethnic groups such as sedentary behaviour (hours watching TV), poor health behaviours in the family (smoking and pre-pregnancy obesity), low income and education, and large birth weight.
Or do the cultural attributes of different ethnic groups affect their entrepreneurial behaviour in the media sector?
Finally, the large differences between ethnic groups in terms of behaviour change were of interest.
Customized information to ethnic groups based on sexual behaviour patterns and local determinants of transmission has rarely been given, at least not on a large scale.
Differences in health seeking behaviour between ethnic groups may impact on the results reported.
Controlled comparisons (Eggan 1954) allow the identification of differences in health knowledge and behaviour between ethnic groups, and differences within ethnic groups associated with citizenship and language.
An earlier study of dietary behaviour in ethnic groups also found an absence of cultural differences in parental perceived barriers or self-efficacy [ 25].
Resnicow et al. make a distinction between interventions and materials that fit in the language and cultural aspects of the target group ("surface structure"), and psychological and social-cultural factors that determine the behaviour of ethnic groups ("deep structure") [ 28].
Currently, there is lack of evidence on whether minority ethnic groups would respond to health behaviour interventions in a similar way to Europeans even at conventional obesity cut-offs, and nothing is known about the effectiveness of interventions if BMI thresholds to define obesity were lowered.
