Behavioural risk factors among young adults in small areas with high mortality versus those in low-mortality areas.

A community-based cross-sectional survey of behavioural risk factors for premature mortality was carried out on a group of 354 adults aged 25-44 from previously identified high-mortality 'black-spots' in Dublin who were compared with 333 others from low-mortality areas. In the black-spot areas, 50.9% of respondents were current smokers versus 28.5% in low-mortality areas and 14.6% took 'sufficient' exercise versus 31.4% in low-mortality areas. People living in black spots were also less likely to make 'healthy' dietary choices than those in low-mortality areas. There is a higher prevalence of behavioural risk factors for premature mortality among young adults living in electoral wards/district electoral divisions (DEDs) with high standardized mortality ratios (SMRs) from all causes than among those in areas with low SMRs. A health promotion programme aimed at increasing exercise levels, reducing smoking and encouraging healthy eating should be aimed at young adults in DEDs with high SMRs.
