The nutritional intakes of the Spanish child and adolescent population are presented, as well as the population at risk of inadequate nutrient status. A random sample of 3534 people aged 2 -24 years were interviewed between 1998 and 2000. Interviews included two 24 h recalls and a general questionnaire and anthropometric evaluations for the entire sample. After excluding under-reporters (18·7 %), the final sample was 2855 individuals (1348 males and 1507 females). The average intake of energy was 9543 kJ in males and 7804 kJ in females, with important variations seen by age group. Energy intake increased with age in both sexes until 14 -17 years, which also applied to almost all of the nutrients studied, with the exception of vitamin C. A decreasing trend in the percentage of energy from carbohydrates was seen in both sexes. At the low socioeconomic level, it was observed that all nutrient intakes were less favourable when compared with higher socioeconomic levels. Nutrients with associated intakes below one-third of the Spanish recommended nutrient intake (RNI) included vitamin D (42 % of the sample) and folate (10 % of females), and the percentages falling below two-thirds of the RNI corresponded to: vitamin D (97 %), vitamin A (60 %), vitamin E (54 %), folate (58 % of females), Fe (23 % of females), vitamin C (8 %), Mg (4·5 %), Ca (5 % of females) and vitamin B 6 (5 % of females). Adolescents aged between 14 and 17 years was the group with the highest nutritional risk, especially among girls. Nutritional adequacy in Spanish children was, in general, adequate, although it is necessary to analyse the implications of high inadequate intakes of vitamins D, E and A, which means that the current recommended intakes should be reconsidered. It should be noted that folate levels should be doubled in the near future.Nutrient adequacy: Recommended nutrient intake: Children: Adolescents: Nutrition survey: SpainThe assessment of nutritional status in childhood and adolescence is critical to understanding the scientific basis of this priority public health issue, and thus in the development of coherent and appropriate policies. However, the majority of dietary information utilized in Spain comes from household or national availability surveys, which means that information for children and adolescents cannot be categorized. Moreover, the majority of nutrition surveys carried out at the regional level in Spain exclude this population group. With the exception of certain studies conducted in communities or cities, detailed information on dietary habits and nutritional status of children and adolescents does not exist in Spain. The enKid Study in Spain was designed and carried out with the aim of filling the gap for this target population. Its rigorous methodology has yielded results (Aranceta et al.

Energy Balance (EB) is an important topic to understand how an imbalance in its main determinants (energy intake and consumption) may lead to inappropriate weight gain, considered to be “dynamic” and not “static”. There are no studies to evaluate EB in Spain, and new technologies reveal themselves as key tools to solve common problems to precisely quantify energy consumption and expenditure at population level. The overall purpose of the ANIBES (“Anthropometry, Intake and Energy Balance”) Study was to carry out an accurate updating of food and beverage intake, dietary habits/behaviour and anthropometric data of the Spanish population (9–75 years, n = 2009), as well as the energy expenditure and physical activity patterns. Anthropometry measurements (weight, height, body mass index, waist circumference, % body fat, % body water) were obtained; diet was evaluated throughout a three-day dietary record (tablet device) accompanied by a 24 h-dietary recall; physical activity was quantified by questionnaire and accelerometers were also employed. Finally, information about perception and understanding of several issues related to EB was also obtained. The ANIBES study will contribute to provide valuable useful data to inform food policy planning, food based dietary guidelines development and other health oriented actions in Spain.

Obesity is considered a major Public Health issue in most developed countries nowadays for its wide spread across population groups, as well as its contribution to the development of chronic diseases, particularly cardiovascular diseases and diabetes. Available population data in Spain from the SEEDO'2000 study show a prevalence of obesity (BMI > or = 30 kg/m(2)) of 14,5% in adults aged 25-60 years, estimates based on individual measurement of body weight and height. Obesity rates are higher among women aged 45 years and older, low social class, living in semi-urban places. Geographical distribution of the problem shows a trend for higher rates towards the South- SouthEast of the country, i.e. Andalucía, Murcia and the Canary Islands. Population data for Spanish children and young people based on the enKid study--cross-sectional study on a random national sample of the population aged 2-24 years--estimate a prevalence of obesity of 13.9% for the whole group. Geographical distribution draws a similar pattern to that described for adults. Higher peaks of the problem are identified between 9-13 years among boys from a low socioeconomical background. The analysis of determinants of obesity in Spanish children and young people show that overweight and obesity is related to absence of breastfeeding, low consumption of fruit and vegetables; high consumption of cakes and buns, soft drinks and butchery products, low physical activity levels and a positive association with time spent watching TV. The joint consensus document produced by the Spanish Association of Pediatrics (AEP), Spanish Society of Community Nutrition (SENC) and Spanish Society for the Study of Obesity (SEEDO) considers a global strategy for the prevention of obesity from early stages in life. The important role of the family and the school setting as well as the responsibility of the Health Administration and Pediatric care in the prevention of obesity is highlighted in the document.
