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)

Poverty: a key social determinant

Lack of adequate material resources to meet basic needs such as food, shelter and health

care

“Structural determinant” rooted in unequal power relationships in society

Myths about the relationship between poverty and mental health

• Mental illness is the result of materialism and fast-paced lifestyles

• Mental health is a luxury item for poor people or for developing countries

• Isn’t misery the obvious result of poverty?

Indicators of “absolute” poverty

– Low educational status– Low income–Hunger– Low material possessions

Page 13: Poverty & Mental Disorder: Breaking the Cycle Vikram Patel, PhD Professor of International Mental Health London School of Hygiene & Tropical Medicine Sangath.

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)

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

Page 19: Poverty & Mental Disorder: Breaking the Cycle Vikram Patel, PhD Professor of International Mental Health London School of Hygiene & Tropical Medicine Sangath.

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

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)

Results: Review 1

• 4 studies (5 articles), all RCTs• Mexico, Ecuador, South Africa and Uganda• Mixed results• Conditional cash transfers and asset

promotion most clearly associated with mental health benefits

• Difficult to draw clear conclusions

Page 28: Poverty & Mental Disorder: Breaking the Cycle Vikram Patel, PhD Professor of International Mental Health London School of Hygiene & Tropical Medicine Sangath.

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

• Improvements in economic status go hand-in-hand with clinical improvements: all studies

What probably works but is very difficult to evaluate?

Poverty alleviation, promoting gender equity, and promoting

fairer income distribution may be the most powerful interventions

to promote mental ill-health
