Predicting human adiposity - sometimes - with food insecurity: Broaden the model for better accuracy

Area of Science:

• Nutrition Science
• Epidemiology
• Human Health

Background:

• Food insecurity is increasingly recognized as a significant public health issue.
• Obesity rates have risen globally, necessitating research into contributing factors.
• The relationship between food access and body weight requires further investigation.

Purpose of the Study:

• To examine the role of food insecurity as a contemporary risk factor for overweight and obesity.
• To evaluate the insurance hypothesis regarding food insecurity and adiposity in adult women.
• To explore additional factors influencing adiposity patterns across different populations and species.

Main Methods:

• Literature review and analysis of existing data on food insecurity and obesity.
• Statistical analysis of data from adult women in high-income countries.
• Comparative analysis of adiposity patterns across species and human contexts.

Main Results:

• Conditional support for the insurance hypothesis was found among adult women in high-income countries.
• Food insecurity is identified as a relevant risk factor for overweight and obesity.
• Variation in adiposity patterns may be influenced by multiple factors beyond food insecurity.

Conclusions:

• Food insecurity plays a role in contemporary overweight and obesity trends.
• The insurance hypothesis offers a partial explanation for observed weight patterns in specific populations.
• Further research is warranted to understand the complex interplay of factors affecting adiposity.
