Key characteristics to successful nutritional interventions
• tailoring interventions to specific minority ethnic groups;• understanding the lifestyles of different minority ethnic groups
and targeting sub-groups;• recognising the relationships between individuals, families and
households;• reinforcing changes in knowledge, behaviours and attitudes by
using a variety of activities;• involving a trusted and recognised community worker health
professionals from the same ethnic background;• using approaches such as community development and peer
education which have proven relatively successful.
