Nutrition and Isolation in a Rural US Population over 80 Years Old: A Descriptive Analysis of a Vulnerable Population

Area of Science:

• Gerontology
• Community Health
• Nutritional Science

Background:

• Factors influencing thriving in rural, community-dwelling individuals aged 80 and above are understudied.
• Social isolation poses a significant risk to this elderly demographic.
• Understanding cohabitation's impact on health is crucial for targeted interventions.

Purpose of the Study:

• To investigate the relationship between cohabitation status and nutritional/health indicators in rural elderly.
• To identify factors contributing to well-being in the 80+ population.
• To inform strategies for improving health outcomes in older adults.

Main Methods:

• Prospective survey of 167 community-dwelling individuals aged 80+.
• Data collected on age, gender, cohabitation (self, spouse, family), and location (suburban, rural, isolated).
• Mini-Nutritional Assessment Short Form (MNA-SF) and Body Mass Index (BMI) were assessed.

Main Results:

• The study population (n=167) was predominantly female (71.9%) with an average BMI of 26.5 (overweight) and MNA-SF score of 11.8 (low-normal).
• Most participants lived alone (49.7%), followed by with a spouse (31.7%) or family (18.6%).
• Living alone correlated with lower MNA-SF scores (p=0.02), while family cohabitation was linked to normal BMI (OR=0.90) and spousal cohabitation to nourished MNA-SF scores (OR=1.69).

Conclusions:

• Self-habitation among rural elderly is associated with increased vulnerability to obesity and malnutrition.
• Spousal and family cohabitation appear protective, correlating with better nutritional status and BMI.
• Interventions should focus on maintaining independence while enhancing the positive effects of cohabitation on nutrition for older adults.
