(DES)INFORMAÇÃO Nunca antes houve um acesso tão facilitado à informação e a uma quantidade astronómica da mesma. Por um lado, a facilitação deste acesso contribuiu para a democratização do conhecimento, o que pode ser visto como positivo, ao possibilitar aos cidadãos o acesso a conhecimento relacionado com comportamentos promotores de saúde. No entanto, a crescente divulgação de informação, nomeadamente nos mei...
This study verified the accuracy of the international BMI references and the allometric BMI reference to diagnose obesity in children and adolescents from the USA. Data from 17 313 subjects were obtained from the National Health and Nutrition Examination Survey between the years 1999-2006 and 2011-2018. Fat Mass Index, Allometric Fat Mass Index and fat mass/fat-free mass were calculated. Receiver operating char...
Objective: To estimate, in a cohort of young Portuguese adults, the environmental impact (greenhouse gas (GHG) emissions, land use, energy used, acidification and potential eutrophication) of diet according to adherence to the Mediterranean Diet (MD). Methods: Data from 1554 participants of the Epidemiologic Health Investigation of Teenagers in Porto (EPITeen) were analysed. Food intake and MD adherence were de...
BACKGROUND AND OBJECTIVES: Evidence is scarce on the clustering patterns of disordered eating dimensions or symptoms and their effects on future cardiometabolic health. This study examines associations of disordered eating trajectory profiles (from 13 to 21 years), with BMI and related cardiometabolic features at ages 21, 24 and 27. METHODS: Participants are from the Epidemiological Health Investigation of Teen...
Objectives To develop an allometric body mass index (ABMI) reference that adjusts the weight in relation to height, taking into account the changes during development (MULT ABMI reference), and to compare it with international BMI references. Methods The MULT ABMI reference was constructed through the LMS method, calculated with 65 644 ABMI observations of 17 447 subjects aged 5–22 years, from the United Kingdo...
Background: Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods: We used data from 3663 population-based studies with 222 million participants that...
This study aimed to examine diet tracking from childhood to adolescence, using 4 time-points, and the influence of socioeconomic and individual characteristics in this transition. The sample included 6893 children from the Portuguese birth cohort Generation XXI with complete information on Food Frequency Questionnaire in at least one of the considered follow-ups. A Healthy Eating Index (HEI), previously develop...
Average adult height is an indicator of population health and a marker of socioeconomic inequalities. This study aimed to assess how socioeconomic differences affect intergenerational height increase between adults born in 1990 and their parents. Data from a population-based cohort of subjects born in 1990 (EPITeen) were analysed. Participants’ adult height was objectively measured. Parental height, education, ...
Children are massively exposed to food marketing through television and other forms of media. Marketing strategies promote unhealthy eating behaviours and contribute to childhood obesity. The main aim of this study was to assess the potential exposure and power of food advertisements aimed at children, broadcasted on Portuguese television. Television data was recorded for two weekdays and two weekend days betwe...
Background and aims: Increased screen exposure is associated with unhealthy eating behaviours and obesity. Screen time (ST) changes from pre-school to school age, and associations with dietary patterns (DP) and obesity remain unknown. We, therefore, analysed ST changes from 4 to 7 years of age, associated factors, and the relation with DP and obesity.Methods and results: We included 4531 children evaluated at 4...
