Wellbeing and its determinants CSP Congress 2009 Liverpool 16 October 2009
Social circumstances and health
20 th century trends in life expectancy in Scotland and 16 other Western European countries Males Year of birth Life expectancy in years Scotland
Health Inequalities u Are they due to: –Poverty? –Diet ? –Tobacco?
Deprivation in 1981
Deprivation in 1991
Deprivation in 2001
Excess Standardised Mortality not explained by deprivation (Scotland v. E&W)
Coronary heart disease mortality Men aged years Age-standardised mortality per 100,000
World Health Organization (1997 and 2003)www.heartstats.org
Smoking prevalence - Europe Males
Smoking prevalence - Europe Females
Comparison of lung cancer mortality in West of Scotland and 3 major cohorts West of Scotland UK doctors American Cancer Society volunteers US veterans Average annual death rate /100,000
Lung cancer mortality by social class never daily cigarette consumption Rate per 10,000 manual non-manual
Risk of death - by level of hopelessness RHR Everson et al 1996
Carotid artery thickening
“.....expresses the extent to which one has a feeling of confidence that the stimuli deriving from one's internal and external environments in the course of living are structured, predictable and explicable, that one has the internal resources to meet the demands posed by these stimuli and, finally, that these demands are seen as challenges, worthy of investment and engagement." Sense of coherence....
For the creation of health the social and physical environment must be: u Comprehensible u Manageable u Meaningful
STRESS AND GRADE OF EMPLOYMENT: MEN Salivary Cortisol Time of Day Steptoe et al. 2003, Psychosomatic Medicine, 65,
Environmental determinants of inflammatory status CRP (median) mg/dl affluent deprived

Its all about the brain
All shapes and sizes!
Attachment theory “Infants develop the attachment behaviours that optimally enhance their survival in their own characteristic environments.” Crittenden, 2000
Attachment theory u Ainsworth –Deep emotional connection that infant develops with primary caregiver –Reflects an “internal working model”expressing the infant’s expectations of parental behaviour in meaningful situations –Basis for development of later relationships u Increasingly recognised as determinant of later emotional, cognitive and social outcomes
“Serve and return” “ The ‘instruction’ to attend to the primary caregiver is genetic, the outcome depends on what happens” Balbernie, 2001
Engaged to respond to danger Disengaged... Who needs to bother about differential calculus?
The Dunedin cohort u 1000 children recruited in late 1972/3 u At age 3, “at risk” children identified on the basis of chaotic circumstances, emotional behaviour, negativity and poor attentiveness u As adults, those “at risk” were more likely to : –be unemployed –have criminal convictions (especially for violence) –been pregnant as a teenager –have a substance abuse problem –exhibit signs of insulin resistance and metabolic syndrome
Telomeres u Ends of chromosomes u Sense and signal damage u Home of repair systems u Integrate energy production and utilisation u Anti-cancer Telomere length predictive for mortality
Telomere length in twins by occupation
“Physical activity” or sweaty exercise? u Are we being too modest in our aspirations for fitness? u Should we make more use of sport as a means to get people active? u By embracing “physical activity”, are we admitting defeat?
