• 1. Introduction
• Older adults are more likely to experience

physical illnesses, which are risk factors for depression

• Paradoxically, most research shows decreased

prevalence of depression with age

• Gender effects are unclear

3

Country Evidence that prevalence

• f depression decreases

with age in high-income countries vs middle- income countries

The Role of Setting

Rural living Some studies show increased levels of depression in seniors living in rural settings whereas others show no difference. 4

Goal

□ Understand the relationship between increased

physical comorbidities and mood in older adults

□ Compare changes in mood across gender and

geographic setting

Analyses – Men and Women

Women 1. High baseline depression 2. Improved self-rated health Men and women experienced similar decreases in depression, but women had higher depression at any given time.

Predictors of Improved Mood

Men 1. High baseline depression 2. Absence of chronic disease Income sufficiency and grip strength were not significant predictors of improved mood. 9

Participants reported fewer depressive symptoms over time despite a decline in physical health. Depression scores were higher in women and middle-income sites compared to men and high-income sites at all times. Best predictor of improved mood: high initial depression score. Physical health declined, but self-rated health increased or remained stable.

Discussion

“

Hum an happiness is a disposition

• f m ind and not a condition of

circum stances.”

• John Locke

Older adults’ improved mood suggests an ability to separate physical illness from successful aging. Low mood in older adults should be considered a red flag, not an inevitable consequence. 11
