Introduction: The HAVISA plan is a Spanish government's policy for the promotion of healthy lifestyles via health messages in television food advertisements. This study evaluated the positive or negative impact (health halo effect) of health messages on food choices and predisposition towards healthy habits of Spanish adolescents., Methods: Randomized controlled study in 11-14 years old adolescents. The intervention group watched television advertisements for unhealthy foods with HAVISA health messages, while the control group watched the same advertisements without them. A self-administered questionnaire measured participants' attitudes towards the products advertised, to diet and physical activity, and recognition of messages. Afterwards they chose between fruit and unhealthy snacks. The differences between the two groups were then compared., Results: A total of 27.2% of the control group versus 29.6% of the intervention group chose fruit (p = 0.54). Both groups displayed high desire for (7.24 vs. 7.40, p = 0.29) and intention to consume (6.67 vs. 6.73, p = 0.63) the unhealthy products advertised. There were no differences in perceived healthiness of these foods (4.11 vs. 4.19, p = 0.74), or perceived importance of a healthy diet (3.17 vs. 3.12, p = 0.55) or physical activity (4.53 vs. 4.51, p = 0.73). Desire for vegetables (2.49 vs. 2.66, p = 0.08) and fruit (3.15 vs. 3.30, p = 0.09) were higher in the intervention group, but the differences were not significant. Only 47.6% of participants noticed the presence of health messages; of these, 31% correctly recalled their content., Conclusion: HAVISA health messages changed neither the attitudes nor immediate eating behaviors of adolescents. There was no immediate healthy-lifestyle promoter or adverse health halo effect, probably due to the messages' low prominence. Further research should evaluate the long-term effect of repeated exposure to health messages., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

Objective: To systematically describe the school nutritional policies of the 17 autonomous communities of Spain., Method: Through a search of bibliographic databases, web pages and other official information systems, 183 documents of interest were identified. Information was systematically collected with the SNIPE (school nutrition index of programme effectiveness) questionnaire, adapted to Spain, and validated by reference staff of the regional government's health and education ministries., Results: The main objective of the policies is to prevent obesity and improve the nutrition of schoolchildren. The 17 autonomous communities cover the school canteen service, 11 cafeteria and vending machines, and 9 the breakfast service. All communities use the Consensus Document on School Food as a reference for the content of the menu and the nutritional quality of the products offered at the school; however, only 4 of them have regulated these aspects. The evaluation of policy objectives ranges from 58.8% of the autonomous communities for food supply to 5.9% for rotation and menu quality., Conclusion: Although all the autonomous communities have standards for the school menu, the standards for the rest of the food supply vary across them; also, evaluation of objectives is scarce and only 4 communities have approved mandatory regulations. Nutritional standards should be reviewed according to current scientific knowledge and enacted by law, in compliance with the current legislation (Act 17/2011)., (Copyright © 2019 SESPAS.

Objective: To describe the nutritional content of products offered in food and drink vending machines at secondary schools in the Madrid Autonomous Community (Spain), and to evaluate these items' adherence to the nutritional recommendations of the National Health System Consensus Document on School Food., Methods: Cross-sectional study of a sample of 330 secondary schools in Madrid across the period 2014-2015. Secondary school vending machines were identified by telephone interview. The products offered in a representative sample of six machines were identified by inspection in situ, and their nutritional composition was obtained from the labelling., Results: A total of 94.5% of the 55 products on offer failed to comply with at least one nutritional criterion of the Consensus Document on School Food. The recommendation relating to sugar content registered the highest level of non-compliance, with 52.7% of products, followed by the recommendations relating to energy (47.3%) and fats (45.5%). The mean number of unmet criteria was 2.2, with this figure being higher in foods than in drinks (2.8 versus 1; p <0.01)., Conclusion: Almost all the products on display in secondary school vending machines in Madrid were in breach of the Consensus Document on School Food, mainly due to an excess of calories, sugars and fats. Compulsory nutritional criteria and a procedure for monitoring adherence should be established, specifying those responsible for performing this task and the corrective measures to be applied in the event of non-compliance., (Copyright © 2017 SESPAS.

Background: Policies restricting access to sugary drinks and unhealthy foods in the school environment are associated with healthier consumption patterns. In 2010, Spain approved a Consensus Document regarding Food at Schools with nutritional criteria to improve the nutritional profile of foods and drinks served at schools. The objective of this study was to describe the frequency of food and drink vending machines at secondary schools in Madrid, the products offered at them and their nutritional profile., Methods: Cross-sectional study of a random sample of 330 secondary schools in Madrid in 2014-2015. The characteristics of the schools and the existence of vending machines were recorded through the internet and by telephone interview. The products offered in a representative sample of 6 vending machines were identified by in situ inspection, and its nutritional composition was taken from its labeling. Finally, the nutritional profile of each product was analyzed with the United Kingdom profile model, which classifies products as healthy and less healthy., Results: The prevalence of vending machines was 17.3%. Among the products offered, 80.5% were less healthy food and drinks (high in energy, fat or sugar and poor in nutrients) and 10.5% were healthy products., Conclusions: Vending machines are common at secondary schools in Madrid. Most products are vending machines are still less healthy.
