What is the poverty obesity paradox?
An seemingly contradictory phenomenon has taken hold in the US: the simultaneous prevalence of obesity and hunger in our population, especially among low-income Americans.
What are some explanations for the obesity paradox?
The obesity paradox may be partly explained by the lack of the discriminatory power of BMI to differentiate between lean body mass and fat mass. Higher mortality in the low BMI categories may be due to the sarcopenic obesity that is characterized by low muscle mass (48).
How does poverty affect obesity?
How is poverty linked to obesity? It has been suggested that individuals who live in impoverished regions have poor access to fresh food. Poverty-dense areas are oftentimes called “food deserts,” implying diminished access to fresh food (7).
What is the obesity paradox in older adults?
Abstract. The prevalence of overweight and obesity in the elderly has become a growing concern. Recent evidence indicates that in the elderly, obesity is paradoxically associated with a lower, not higher, mortality risk.
Are obese people food insecure?
Among the 12 states, the prevalence of obesity was 27.1% overall, 25.2% among food secure adults, and 35.1% among food insecure adults. Food insecure adults had 32% increased odds of being obese compared to food secure adults. … One in three food insecure adults were obese.

Does the obesity paradox exist?
Obesity paradox in overweight and obese patients with coronary heart disease. Ten years ago, Gruberg and coworkers observed better outcomes in overweight and obese patients with coronary heart disease undergoing percutaneous coronary intervention compared with their normal-weight counterparts.
Can obesity be protective?
Despite the known association between obesity and mortality in the general population,8 numerous studies have reported that obesity confers a survival advantage among patients with cardiovascular disease, cancer, diabetes, respiratory disease, and renal disease, among other conditions.
How does poverty contribute to disease?
Overcrowded and poor living conditions can contribute to the spread of airborne diseases such as tuberculosis and respiratory infections such as pneumonia. Reliance on open fires or traditional stoves can lead to deadly indoor air pollution. A lack of food, clean water and sanitation can also be fatal.
Why does poverty cause obesity and life long problems?
Instead of large supermarkets, poor neighborhoods have a disproportionate number of fast food chains and small food stores providing cheap, high-fat foods. Economic insecurity – such as trouble paying bills or rent – leads to stress, and people often cope by eating high-fat, sugary foods.

Obesity is generally caused by eating too much and moving too little. If you consume high amounts of energy, particularly fat and sugars, but do not burn off the energy through exercise and physical activity, much of the surplus energy will be stored by the body as fat.
Why is obesity undesirable in the elderly?
Obesity puts people at risk for heart disease, type 2 diabetes, high blood pressure, stroke, and some types of cancer. In patients over 65, the increase in chronic diseases associated with aging reduces physical activity and exercise capacity, making it more difficult for elderly persons to lose weight.
What is Sarcopenic obesity?
Sarcopenia is defined as the age-related loss of muscle mass and strength or physical performance. Increased amounts of adipose tissue often accompany sarcopenia, a condition referred to as sarcopenic obesity. The prevalence of sarcopenic obesity among adults is rapidly increasing worldwide.
