In the most deprived 15% of areas in Scotland, though, men could only expect 57.3 years of healthy life and women 59 years. More babies born to mothers living in the most deprived fifth of areas have a low birth weight than those born to mothers living in the most affluent areas: 9% compared to 5%. People struggling with poverty and low income have poorer mental health and wellbeing than those with higher incomes or who find it easy to manage financially. There are large and increasing inequalities in deaths amongst young adults due to drugs, alcohol, violence and suicide. Equally Well 2008
