Nutritional state, food consumption and lifestyle of pupils in Campinas-SP The present work tried to analyze the nutritional state, the food consumption and the lifestyle of kids and teenagers within the relatively most developed urban center in Sao Paulo State. These pupils' access to food services available at the learning centers (Brazilian School Meal Program-PNAE and the school canteens/cafeterias) was also investigated. For so, a transversal-nature study was performed, having as base a 324-student sampling, aged between 6 and 14, enrolled in six schools in the Campinas public learning network, in Sao Paulo State. Along with the students, an anthropometric evaluation was performed and, for determining the nutritional state, the Zscores for age-ZAI-and the Body Mass Index percentage distribution-IMC-were calculated and analyzed, adopting two pre-established parameters (one international and one national), based on reference populations. The food consumption was identified by using a 24-hour recordkeeper and the pieces of information related to the lifestyle and the adhesion to the services available at the units were evaluated through specifically-elaborated questionnaires. With parents and guardians, we obtained information related to the pupils' socioeconomic condition. As far as the nutritional state is concerned, we highlight the small proportion (1.6%) of students classified as having a height deficit for their age (ZAI <-2). Regarding the IMC, proportions of 5.6%, 79.0% and 15.4% were identified for low weight (3 rd P ≤ IMC), eutrophia (5 th P ≤ 85 th < P) and overweight (IMC ≥ 85 th P), respectively, adopting an international references. Prevalence of 2.8% (underweight), 77.4% (eutrophia) and 19.8% (overweight) were observed using national references. The latter was more in agreement with the process of nutritional transition happening in the country: tendency of reduction in the serious forms of malnutrition and increase on the prevalence of overweight. Regarding the food consumption, 65% of the students' diets are inadequate in terms of participation of at least one of the energy macronutrients. An expressive share of the students revealed a reduced intake of energy, fibers, vitamin A, folic acid, pantothenic acid, calcium, phosphorus, magnesium and potassium. High cholesterol and sodium consumption were observed for a substantial proportion of students. The analysis on the participation of food groups in the Total Energy Value-VET-revealed that the basic, vegetal foods contributed with 38.6% of the diet's energy contents, highlighting the expressive participation (31.7%) of the animal ones. As far as the lifestyle is concerned, 29.6% of the girls and 19.0% of the boys were considered sedentary. The adhesion of students to the school food services was considered expressive: 75.3% consumed the meals provided by the PNAE, being 51.0% effective eaters (between 4 and 5 days a week). Circa 76% of the students adhered to the school cafeterias, being the highest proportion (52.1%) bought food sporadically (...
