The aim of the work was to assess the nutritional status in people dwelling in the country in Lower Silesia and Opole voivodships, including gender and age.

Material and methods:
The research was done among 315 people dwelling in villages of provinces: Lower Silesian and Opole. The measurements of body mass, as well as its content, were made using the analyzer of the body content. Thanks to the examination there were gathered information about the content of adipose and lean body tissue, bone mass, muscles mass, and total amount of water, including intracellular and extracellular water.

Results:
Over 50% of the examined people had incorrect body mass. The problem was more common in men than women. Every fourth respondent was characterized by too much fat in the body, and every sixth too low content of water. Abdominal obesity was more common in the studied men than in women.

It is advisable to monitor the nutritional status in order to evaluate the effectiveness of the activities carried out to promote a healthy lifestyle and physical activity and the possibility of better planning for further prevention.
