Why social determinants?
“Social justice is a matter of life and death. It affects the way people live, their consequent chance of illness and their risk of premature death”
--WHO Commission on Social
Determinants of Health, 2008

“We are at a crucial juncture….action on social determinants of health is not only vitalfor health equity but has other highly desirable societal outcomes including social cohesion, reduction of crime and civil unrest, a more educated workforce and the freedom for people to lead lives they have reason to value.
(Marmot, Bull WHO 2011)

care

Indicators of “absolute” poverty
– Low educational status– Low income–Hunger– Low material possessions
Is there an association between depression and
absolute poverty?• 115 studies• Most studies showed
statistically significant association* between indicators of poverty and depression
• Poverty strongly associated with higher rates of depression across age ranges in rural and urban areas
• Poverty associated with:– Increased prevalence– Increased severity– Longer course and worse
outcome * (p<.05; OR with
95%CI>1)
13
Other mental disorders
• Similarly strong associations between absolute poverty and a range of other mental disorders and disabilities, notably:– Chronic psychoses– Substance use disorders– Developmental disabilities

How living in poverty can lead to mental ill-health
• Material stressors, e.g. hunger, indebtedness• Noisy, crowded, polluted and unsafe living
conditions• Higher burden of physical ill-health• Inadequate access to good health care• Impairment of early child development due to
malnutrition• Insecurity and humiliation of living in poverty
19
The humiliation of living in poverty
“There’s nothing to eat. We’re constantly hungry. There’s nothing to wear. There’s no money to buy the child boots, or notebooks, pens or book bag. My life is just grief. I gave birth to these kids and I have to raise them. But if I didn’t I would have put a rope around my neck and hung myself a long time ago.” (woman, Ukraine)
-from: Narayan et al, Voices of the Poor, OUP 2000
20
The insecurity of the poor
“…the employer can keep you up to three months on a temporary contract without signing a permanent contract. At the end of the third month, he just says ‘go away’ without explaining how and why... If you say anything he says there are thousands like you waiting for your position.” (a man, Plovdiv, Bulgaria)
(from ‘Voices of the Poor’, OUP 2000)

• Difficult to draw clear conclusions
27
Results: Review 2
• 9 studies: China (3), India (2), Iran (1), Nigeria (1), Thailand (1), Uganda (1)
• Of 19 associations tested:– 10 showed a significant positive effect on economic
status– 9 showed a non-significant yet positive effect
• Benefits for individuals and households/families
