Morbidity and physical functioning in old age: differences according to living area.

Area of Science:

• Gerontology
• Public Health
• Epidemiology

Background:

• Elderly populations face varying health challenges based on geographic location.
• Understanding disparities in morbidity and functional status is crucial for targeted interventions.

Purpose of the Study:

• To compare morbidity and functional status between elderly individuals in urban and rural Swedish communities.
• To identify differences in disease prevalence and disability patterns based on living area.

Main Methods:

• A prospective cohort study (Kungsholmen-Nordanstig Project) involving adults aged 75+.
• Standardized clinical examinations and direct disability assessments were conducted in urban (Stockholm) and rural (Nordanstig) areas.
• Data collected from 1,222 urban participants and 919 rural participants.

Main Results:

• Cardiovascular disease was prevalent in both areas, but stroke, diabetes mellitus, and Parkinson's disease were more common in the rural population.
• Rural elderly individuals were more likely to have multiple chronic conditions (OR=1.9).
• Significant differences in population attributable risk (PAR) for disability were observed for stroke, diabetes, fractures, and hearing impairment between urban and rural areas.

Conclusions:

• Distinct differences exist in disability, morbidity, and disease patterns between urban and rural elderly populations.
• The rural elderly cohort exhibited higher levels of disability and a greater burden of disease compared to the urban cohort.
• Area-specific PAR analysis revealed significant variations in how chronic conditions contribute to disability risk in different living environments.
