The current situation in dietary habits, nutritional status and physical activity levels in school population determine the risk of future chronic diet-related diseases. The actual descriptive research aimed to identify the dietary habits, physical activity levels and nutritional status in a school population group of 80 children between 9 and 11 years old. Nutritional assessment performed under BMI showed that 18% of children were overweight and 19% were at risk for stunting. The level of physical activity assessed by the IPAQ-C questionnaire, found that 50.9% of children do not practice physical activity in the week. 29.7% practice moderate physical activity and 23% practice intense physical activity. 79% of the population spends between 1-4 hours a day to watch television or play video games. In dietary habits, the consumption of food within a frequency from 2 to 6 times/week corresponded to: fruit (3.7%), vegetables (2.5%), sugary drinks (20%), whole milk (28%), buttermilk (40%), beef (65%), and potato (44%). White rice (54%) within a frequency from 2 to 5 times/day and water (63%). The most common of food preparation for consumption was boiled (48%). In conclusion, the low consumption of fruits and vegetables and sedentary activities, are conceived as risk factors to develop chronic diseases transmittable at a Young age, in this important stage for fomenting nutrition and a healthy life style.
