RESUMEN
BACKGROUND: The consumption of ultra-processed foods (UPFs) is associated with an increased risk of noncommunicable diseases and mortality in adults. The aim of this study was to analyse the association between mealtime television (TV) watching and UPF consumption in childhood. MATERIALS AND METHODS: Participants in the SENDO project recruited in 2015-2023 were classified into three categories based on the frequency at which they watched TV during meals. Dietary information was collected with a validated 147-item semi-quantitative food frequency questionnaire. Generalized mixed models were used to compare mean UPF consumption between groups after accounting for the main confounders. The predictive margins of participants who had a free sugar intake >10% of their energy intake in each category were also calculated. RESULTS: Totally 970 subjects (482 girls) with a mean age of 5.00 years (SD = 0.85) were studied. Children who watched TV during meals ≥4 times/week consumed a mean of 4.67% more energy from UPF than those who watch TV <3 times/month. The adjusted proportions of children who had a free sugar intake >10% of their energy intake in the categories of <3 times/month, 1-3 times/week and ≥4 times/week exposure to TV during meals were 44.9%, 45.9% and 58.7%, respectively. CONCLUSION: TV watching during meals is associated with higher consumption of UPFs and a higher risk of exceeding 10% of TEI in free sugar intake in childhood.

BACKGROUND: Youth is a vulnerable period. To classify lifestyle behaviors and its relationship with health-related outcomes of Spanish children and adolescents. METHODS: Cross-sectional study including 3261 children aged 7.5-17.5 y (52.8% females). Physical activity (PA), screen-time, sleep time, adherence to Mediterranean diet (MD), weight status (WS) by validated methods. Cluster analysis was run considering chronological age. RESULTS: Six clusters were identified: C1: high screen time, low adherence to MD and sleep time (n = 431,13.20%); C2: high WS, medium adherence to MD,high sleep time, and low screen time (n = 466,14.30%); C3: young group with low screen time and high PA, adherence to MD and sleep (n = 537,16.40%); C4: worst profile regarding adherence to MD, PA, WS and sleep time (n = 609,18.70%); C5: low screen time and PA, high sleep time (n = 804,24.70%); C6: high PA and screen time, low WS (n = 414,12.70%). Mean absolute values were statistically different among PA levels, screen and sleep time, adherence to MD, age, and WS (all p < 0.001). CONCLUSIONS: The most prevalent pattern was low levels of PA, MD, and screen time, and high sleep time. The second most prevalent was characterized by very low levels of PA, sleep time, and adherence to MD, and high screen time, and WS in adolescents. IMPACT STATEMENT: The main identified lifestyle behavior was poor physical activity, low adherence to Mediterranean Diet and high screen and sleep time. Children should increase physical activity levels, adherence to Mediterranean diet, decrease screen and sleep the appropriate hours per day. Families, schools, and medical communities must work together to gloss over present and future diseases. Sleep time had not been previously included in cluster analysis with physical activity, sedentary behaviors, obesity, and nutritional status, thus the present data open a new perspective in Spanish population. Health policies should focus on promoting physical activity, Mediterranean diet, adequate sleep and reducing screen time.

The aim of this study is to evaluate if screen time and parents' education levels are associated with adherence to a Mediterranean dietary pattern. This cross-sectional study analyzed a representative sample of 3333 children and adolescents (8 to 16 years) included in the Physical Activity, Sedentarism, lifestyles and Obesity in Spanish youth (PASOS) study in Spain (which ran from March 2019 to February 2020). Data on screen time (television, computer, video games, and mobile phone) per day, Mediterranean diet adherence, daily moderate or vigorous physical activity, and parents' education levels were gathered using questionnaires. A descriptive study of the variables according to sex and parents' education level was performed. Logistic regression models (adjusted by sex and weight status) were fitted to evaluate the independent association between screen time and Kids' level of adherence to the Mediterranean diet (KIDMED) index, as well as some of its items. A greater amount of screen time was associated with worse adherence to the Mediterranean diet; a lower consumption of fruit, vegetables, fish, legumes, and nuts; and a greater consumption of fast food, sweets, and candies. A lower parents' education level was associated with worse adherence to the Mediterranean diet. It is necessary to promote the responsible, limited use of screen time, especially in children with parents with a lower education level.
RESUMEN
INTRODUCTION: Physical activity (PA) is essential to healthy mental and physical development in early life. However, the prevalence of physical inactivity, which is considered a key modifiable driver of childhood obesity, has reached alarming levels among European youth. There is a need to update the data for Spain, in order to establish if current measures are effective or new approaches are needed. METHODS AND ANALYSIS: We present the protocol for Physical Activity, Sedentarism, lifestyles and Obesity in Spanish youth (PASOS). This observational, nationally representative, multicentre study aims to determine the PA levels, sedentary behaviours and prevalence of physical inactivity (defined as <60 min of moderate to vigorous PA per day) in a representative sample of Spanish children and adolescents. The PASOS study has recruited a representative random sample of children and adolescents aged 8-16 years from 242 educational centres in the 17 'autonomous regions' into which Spain is divided. The aim is to include a total of 4508 youth participants and their families. Weight, height and waist circumference will be measured by standardised procedures. Adherence to the Mediterranean diet, quality of life, sleep duration, PA and sedentary behaviour are being measured by validated questionnaires. PA is measured by the Physical Activity Unit 7-item Screener. A representative subsample (10% of participants) was randomly selected to wear accelerometers for 9 days to obtain objective data on PA. Parents are asked about their educational level, time spent doing PA, diet quality, self-perceived stress, smoking habit, weight, height, their child's birth weight and if the child was breast fed. ETHICS AND DISSEMINATION: The study was approved by the Ethics Committee of the Fundació Sant Joan de Déu, Barcelona, Spain. Main findings of the study will be disseminated to the scientific community and to general public by media conferences, social media and a website. TRIAL REGISTRATION NUMBER: ISRCTN34251612.

BACKGROUND: Behaviour change interventions targeting physical activity, diet, sleep and sedentary behaviour of teenagers show promise when delivered through smartphones. However, to date there is no evidence of effectiveness of multicomponent smartphone-based interventions. Utilising a user-centred design approach, we developed a theory-based, multi-dimensional system, PEGASO Fit For Future (PEGASO F4F), which exploits sophisticated game mechanics involving smartphone applications, a smartphone game and activity sensors to motivate teenagers to take an active role in adopting and maintaining a healthy lifestyle. This paper describes the study protocol to assess the feasibility, usability and effectiveness (knowledge/awareness and behavioural change in lifestyle) of the PEGASO system. METHODS: We are conducting a quasi-experimental controlled cluster trial in 4 sites in Spain, Italy, and UK (England, Scotland) over 6 months. We plan to recruit 525, in a 2:1 basis, teenagers aged 13-16 years from secondary schools. The intervention group is provided with the PEGASO system whereas the comparison group continues their usual educational routine. Outcomes include feasibility, acceptance, and usability of the PEGASO system as well as between and within group changes in motivation, self-reported diet, physical activity, sedentary and sleeping behaviour, anthropometric measures and knowledge about a healthy lifestyle. DISCUSSION: PEGASO F4F will provide evidence into the cross-cultural similarities and differences in the feasibility, acceptability and usability of a multi-dimensional smartphone based behaviour change intervention for teenagers. The study will explore facilitating factors, challenges and barriers of engaging teenagers to adapt and maintain a healthy lifestyle when using smartphone technology. Positive results from this ICT based multi component intervention may have significant implications both at clinical level, improving teenagers health and at public health level since it can present an influential tool against the development of chronic disease during adulthood.

BACKGROUND: The Mediterranean diet serves as a proxy of a high-quality diet. Although several factors are known to affect a child's ability to follow a high-quality diet, no prospective data are available on factors that influence adherence to a Mediterranean diet among children. Our objective was to investigate the association of Mediterranean diet adherence with eating behaviors, lifestyle habits, and maternal education in a prospective cohort of children. METHODS: The present prospective cohort analysis included 1639 children aged 8-10 years. The study was carried out during two academic years, 2012/2014, with an average follow-up of 15 months. Eating behaviors, physical activity, and adherence to Mediterranean diet were estimated by the Dutch Eating Behavior Questionnaire for Children, the Physical Activity Questionnaire for Children, and the KIDMED index, respectively. RESULTS: Multivariate linear regression analysis adjusted for sex, age, maternal education, baseline adherence to the Mediterranean diet, and intervention group revealed a significant (pâ¯<â¯0.01) inverse association of external eating and screen time with adherence to the Mediterranean diet at follow-up (mean of 15 months). The opposite association was found for meal frequency and physical activity (pâ¯<â¯0.02). A high level of maternal education increased the odds of a child's high adherence to the Mediterranean diet (ORâ¯=â¯1.56 CI 1.13; 2.14) compared to peers whose mothers had only a primary education. CONCLUSIONS: Screen time, physical activity, meal frequency, and external eating predict adherence to the Mediterranean diet independently of baseline diet quality. Maternal education level is an important prospective determinant for the adherence to the Mediterranean diet. TRIAL REGISTRATION NUMBER: ISRCTN68403446.

Results of community-based childhood obesity intervention programs do not provide strong evidence for their effectiveness. In this study, we evaluated the effect of the Thao-Child Health Program (TCHP), a community-based, multisetting, multistrategy intervention program for healthy weight development and lifestyle choices. In four Catalan cities, a total of 2250 children aged 8 to 10 years were recruited. Two cities were randomly selected for the TCHP intervention, and two cities followed usual health care policy. Children were selected from 41 elementary schools. Weight, height, and waist circumference were measured at baseline and after a mean follow-up of 15 months. Physical activity and adherence to the Mediterranean diet were measured with validated questionnaires. Generalized estimating equations (GEE) models were fitted to determine the intervention's effect on body mass index (BMI) z-score, waist-to-height ratio, Mediterranean diet adherence, and physical activity. Fully adjusted models revealed that the intervention had no significant effect on the BMI z-score, incidence of general and abdominal obesity, Mediterranean diet adherence, and physical activity. Waist-to-height ratio was significantly lower in controls than in the intervention group at follow-up (p < 0.004). CONCLUSIONS: The TCHP did not improve weight development, diet quality, and physical activity in the short term. What is Known: ⢠There is inconsistent evidence for the efficacy of school-based childhood obesity prevention programs. ⢠There is little evidence on the efficacy of childhood obesity intervention programs in other settings. What is New: ⢠This paper contributes information about the efficacy of a multisetting and multistrategy Community Based Intervention (CBI) program that uses the municipality as its unit of randomization. ⢠This CBI had no effect on the prevention and treatment of childhood obesity in the short term.

Fundamento: El Proyecto PEGASO pretende diseñar un sistema tecnológico dirigido a adolescentes europeos para fomentar hábitos de vida saludables. El objetivo de este estudio fue explorar las percepciones de adolescentes, sus progenitores y profesores el uso de las tecnologías móviles, la salud y la influencia de las tecnologías en la promoción de estilos de vida saludables en cuanto a alimentación y actividad física. Métodos: Estudio cualitativo basado en datos primarios obtenidos mediante análisis de cuatro grupos focales (tres de adolescentes entre 13 y 15 años y uno de adultos, formado por padres y profesores) que se realizaron en abril y mayo de 2015. Las transcripciones se analizaron bajo la perspectiva del análisis del contenido. Resultados: Emergieron cuatro categorías: 1: marco social y cultural, 2: adolescentes y salud, 3: papel de la tecnología en la vida de los adolescentes y 4: uso de la tecnología para adquirir hábitos más saludables. En cada categoría se identificaron subcategorías vinculadas al nexo entre adolescentes y salud: concepto holístico de salud, identificación de salud/enfermedad con edad adulta, relación de la salud con sentirse en buena forma y aceptación social. En relación al papel que juega la tecnología en la vida de los adolescentes, las subcategorías obtenidas fueron: conexión con otros, elemento de entretenimiento/juego, uso omnipresente del móvil y riesgos asociados a la dependencia excesiva de la tecnología. Las diferencias entre adolescentes y adultos fueron mínimas. Conclusiones: Tanto adolescentes como sus progenitores y profesores consideraron que la tecnología puede ser un buen aliado para fomentar hábitos saludables. El uso de la tecnología es eficaz en la medida que les ayude a mejorar y mantener su autoestima, de forma divertida y utilizando sus propios códigos de comunicación (fundamentalmente audiovisuales), partiendo de una percepción holística e integrada de la salud (AU)
Background: The PEGASO Project aims to design a technological system aimed at European adolescents to promote healthy lifestyles. The objective was to explore teenagers and their parents and teachers perceptions with regards to mobile technology use in promoting a healthier lifestyle, in terms of food and physical activity. Methods: Qualitative study based on primary data obtained through four focus groups analysis (three teenager groups between 13 and 15 y and 1 parent/ teacher group). Verbatim transcriptions have been analysed following content analysis perspective. Results: Four different categories were identified: 1: social and cultural context, 2: adolescents and health, 3: role of technology in teenagers lives and 4: use of technology to acquire healthier habits. Each category helped to arise various subcategories linked to the relation between teens and health: holistic health concept, health/disease perception directly related with feeling physically fit and social acceptance. With regards to technology, the arisen themes were: feeling connected with others, importance of entertainment/games, omnipresent use of Smartphones and risk of excessive dependence on technology. The difference between teens and adults with regards to health and technology categories were not significant. Conclusions: Both teens and adults think that for technology to be effective in acquiring healthier habits it has to help teens to improve and maintain their self-esteem, in an entertaining way and using their own communication codes, mainly audio-visual ones, always under the umbrella of a holistic and integrated perception of health (AU)
