Background and aims. Bad eating habits, physical activity low level and sedentary behavior have been associated with increased dyslipidemia, abdominal adiposity and overall cardiometabolic risk in childhood. The impact of nutritional education and intervention was evaluated on dietary habits, physical activity and cardiometabolic risk in school children.
Methods. Children (n=222), aged 7-10 years, received questionnaires on food habits and physical activity. Daily energy intake (DEI) was estimated using 24 hours recall, followed by 3 days recall and record. Children were instructed to follow-up nutritional advices at d0, d30, d90 and d180. Blood pressure and biochemical parameters were measured at d0 and d180.
Results. Children presented normal weight (NW) 63%, 19% overweight (OW), 9% obese (O) and 10% thinness (T). At d0. DEI (Kcal/d) represented 2008, 1780,, 2211, and 2567 in NW, T, OW and  O, respectively, while daily energy expenditure (DEE) was 1898, 1794, 1807 and 1989 Kcal/d,respectively.  There was no difference in proteins, lipids and carbohydrates intakes between NW, T and OW. High lipids and low carbohydrates consumption were noted in O vs NW. Blood pressure and glycemia were higher in OW and O groups than NW, whereas, no difference was observed in other parameters. At d30, decreased DEI and increases DEE were noted in NW, OW, and O, and remained unchanged at d90 and d180. Low values of total cholesterol, C-LDL, triacylglycerols and uric acid were noted in OW and O at d180.
Conclusion. Nutritional education can change positively sedentary and eating behavior, and lipid profile.
