Introduction: childhood obesity is a major public health problem, affecting children even at early ages. Objective: to assess the impact of dietary intervention and relatively simple physical activity on the nutritional state of preschoolers. Method: this was an intervention study in public daycare centers targeting children from 2 to 4 years of age, in the State of São Paulo. The sample consisted of 9 daycare centers covering 578 children, with 264 children in the intervention group (IG) and 314 in the comparison group (CG). Intervention was focused on modifications in diet and physical activity, avoiding overloading the routine of daycare centers, for duration of one year. A zBMI score > 1 (zBMI) and < 2 was considered risk of being overweight, and > 2 zBMI was considered excess weight (overweight and obese). Analysis was done by frequency calculations, comparisons of proportions by χ2, mean comparisons by t-student and calculations according to Pearson’s correlation coefficient. Results: IG showed an inverse correlation between the initial zBMI of the children and the difference with the zBMI at the end of the intervention (rP = -0.39, p <0.0001). The mean difference of zBMI of the overweight children in IG between the beginning and the end of the study period was negative (-0.46 z score), indicating weight reduction, while the children in the CG was positive (+0. 17 z score) (p = 0.0037). Conclusion: intervention in diet and physical activity in overweight preschool children in daycare centers could have a favorable impact on the evolution of their nutritional state.

In Brazil, smoking incidence varies between 9.5% and 21.2% and it is more common among men. In college students incidence can reach 14% depending on the region, which is quite disturbing. Joining college is a crucial period for the commencement or maintenance of smoking. The Knowledge among college students about tobacco use is critical to devise strategies for intervention in this population. The objectives were to establish the occurrence of smoking and risk factors, nicotine dependence in college students and college goers. We interviewed students, teachers and administrative personnel from the Philosophy and Science School at UNESP at Marilia, from both sexes, regardless their age, which visited the First Week Against Tobacco event. The sociodemographic data, smoking status, time as a smoker, cigarettes smoked, date when they started smoking, history of smoking in the family, friends or associates were questioned. We also assessed the degree of motivation to quit smoking and the degree of nicotine dependence. Data were presented using descriptive statistics. Comparisons between categorical variables were made using the chi-square test (p <0.05). A total of 432 people, 180 men and 252 women, average aged 22.6 ± 6.9 years were researched. From the volunteers studied, 267 (61.8) had tried cigarettes and 171 of them (64%) reported that they were offered by friends. As a whole, 79 (18.3%) of these people were smokers, 52 (65.8%) reported intending to quit smoking and in 37 of them (46.8%), the degree of nicotine dependence was very low. Of all the smokers, 63 had smokers in the family and all of them had friends who smoked. 28.9% of all men were smokers and 10.7%of all women. The occurrence of smoking was 18.3% and the risk factor associated to smoking habit is related to friendship and family, and very low nicotine dependence.
