Assessing neighbourhood effects on the health of older people using ELSA Iain Lang Epidemiology & Public Health Group, Peninsula Medical School
Two of ELSA’s strongest components: health/functioning and micro-economics • Neighbourhood context is associated with poor health in later life – is this simply a “compositional effect”? • Linkage of ELSA data to quintiles of the Index of Multiple Deprivation (IMD 2004) available from NatCen on request
Outcomes assessed Mobility: change in gaitspeed from Wave to Wave 2; incident self-reported walking problems Cognition: standardized cognitive function score Obesity and waist circumference Frailty: frailty index score
Potential confounders(differ by analysis) • Age, sex, rural-urban, population density, duration of residence, level of education, number of comorbidities, smoking status, BMI, level of physical activity, visual problems, hearing loss, eyesight, depressive symptoms, alcohol consumption,
Standardized cognition score by level of neighbourhood deprivation, unadjusted
Standardized cognition score by level of neighbourhood deprivation, fully adjusted, ages 70+
Rate of incident mobility problems after 2-year follow-up by level of neighbourhood deprivation, unadjusted, ages 70+
Self-reported Measured Odds ratios of having incident mobility problems after 2 years, by level of neighbourhood deprivation (adjusted)
Odds ratios of obesity and high waist circumference by level of neighborhood education deprivation
What’s going on here? Do differences by level of neighbourhood deprivation represent uncontrolled confounding by individual- or household-level differences?
What’s going on here? Do differences by level of neighbourhood deprivation represent uncontrolled confounding by individual- or household-level differences? What are the mechanisms by which neighbourhood deprivation influences individual health and well-being in older people?
