Aim of the study: Analysis of nutrition disorders, learning about eating habits and characterising physical activity among primary school children at the age of 6–13, living in the rural areas of Silesia and Opole Provinces in Poland. Material and methods: The study included the parents of children at the age 6–13 attending selected primary schools and living in rural areas of Silesia (Wielowieś, Boruszowice, Wojska, Potępa, Świerklaniec) and Opole (Kielcza) Provinces. The research group comprised 410 pupils: 217 boys (52.93%) and 193 girls (47.07%). On the basis of obtained data, BMI index was calculated and a nutritional level was assessed. Moreover, the statistical analysis of dietary habits and physical activity of studied children was also performed. Results: Nearly 38% of studied children are overweight or obese. Furthermore, 17% are malnourished. Every second child has a proper number of meals per day. Above 60% of pupils eat first and second breakfast every day. Merely 3.66% of children eat five or more portions of fruit and vegetables daily. Less than 62% of students declare to drink milk or eat dairy products. Over 83% of the respondents declare that their children eat meat several times a week. Over 28% of children have sweets or salty snacks every day. As for physical activity, about 59% of children prefer spending free time outdoors but approximately 22% of pupils practise sport regularly. Conclusion: This study revealed that students attending primary schools in selected rural areas are characterised by improper dietary habits. Their way of eating is not balanced in a right way – it is mainly based on meat and snacks like sweets. Furthermore, children eat few fruit and vegetables, highfibre products and drink little milk. Behaviours connected with physical activity are also inappropriate – children dedicate too little time to physical activity a week.
