Nutritional status of the elderly in Poland

The elderly are at greater risk of underweight and the associated risk of protein and energy malnutrition. On the other hand, the lower energy requirement with an often too high intake from the diet leads to the development of overweight and obesity.

The aim of the study was to assess the prevalence of underweight, overweight and obesity, including abdominal obesity in Polish elderly.

The study included 300 men and 304 women aged 65 and over from all over the country. The nutritional status was assessed on the basis of anthropometric measurements: body height and weight as well as waist and hip circumferences. Based on BMI (Body Mass Index), the prevalence of underweight (<20.0), overweight (25.0-29.9) and obesity (≥30.0) was assessed. WHR (Waist-to-Hip Ratio) was used to assess abdominal obesity (≥1.0 in men and ≥0.85 in women). Waist circumference was also analysed with regard to increased risk of metabolic complications (≥94 cm in men and ≥80 cm in women).

Underweight was found in 1.3% of men and 4.3% of women. 55.3% of men and 40.1% of women were overweight, 20.3% and 21.7% were obese, respectively. In the case of people with excess body weight, abdominal obesity was observed in 50% of men and 70.1% of women. Waist circumference indicating an increased risk of metabolic complications was found in 44.1% of men and 67.5% of women.

The prevalence of overweight and obesity in Polish elderly was high, especially in men. Overweight and obese people often had abdominal obesity. This type of obesity was more common in women. Elderly people, especially women, often have an increased risk of metabolic complications due to high fat accumulation in the abdomen. It was even found in elderly who were not overweight nor obese. Some elderly, mostly women, were underweight which increased the risk of protein and energy malnutrition.
