“…41 On the other hand, a possible causal factor for the higher occurrence of overweight girls is early development. 42 Females experience growth spurts one to two years before males, at around 9.5 years of age, 43 and, according to Benedet et al, 44 anticipated body and sexual development is closely associated with body fat.…”

Rev. paul. pediatr.

Objective: To verify the occurrence of overweight in children and adolescents with phenylketonuria and to identify possible causal factors.Data sources: A systematic review was performed in the SciELO, PubMed and VHL databases using the descriptors "Phenylketonurias", "Overweight", "Child" and "Adolescent". Original articles conducted with children and adolescents, published between 2008 and 2018 in Portuguese, English or Spanish languages were included.Data synthesis: A total of 16 articles were identified and, after screening procedures, 6 studies were selected for the review.Overweight in children and adolescents with phenylketonuria was a frequent occurence in the studies included in this review, ranging from 7.8 to 32.6%. The female sex was the most affected by the nutritional disorder. Furthermore, a high caloric intake combined with a lack of stimuli to practice physical activities were main factors associated with the excessive weight in the population of interest.Conclusions: Excess weight can be considered a common outcome in children and adolescents with phenylketonuria. It is mainly caused by inadequate food consumption and sedentary lifestyle.The importance of early identification of nutritional disturbances in children and adolescents with phenylketonuria should be emphasized, in order to prevent associated chronic diseases and to promote health by encouraging continued healthy eating habits and the regular practice of physical exercises.Objetivo: Verificar a ocorrência de excesso de peso em crianças e adolescentes com fenilcetonúria e identificar possíveis fatores causais. Fontes de dados: Revisão sistemática realizada nas bases de dados Scientific Eletronic Library Online (SciELO), Publisher Medline (PubMed) e Biblioteca Virtual em Saúde (BVS) com os descritores "Phenylketonurias", "Overweight", "Child" e "Adolescent". Foram incluídos artigos originais sobre crianças e adolescentes, publicados entre 2008 e 2018 nos idiomas português, inglês ou espanhol. Síntese dos dados: Foram identificados 16 artigos e, após aplicação dos procedimentos de seleção, 6 estudos foram selecionados para compor a revisão. O excesso de peso em crianças e adolescentes com fenilcetonúria foi evento frequente nos estudos incluídos na presente revisão, variando de 7,8 a 32,6%. Aponta-se o sexo feminino como o grupo mais acometido pelo distúrbio nutricional.O principal fator associado ao excesso de peso na população de interesse na população de interesse foi o consumo calórico elevado aliado à falta de estímulos para a prática de atividades físicas.Conclusões: O excesso de peso pode ser considerado um desfecho comum em crianças e adolescentes com fenilcetonúria, sendo ocasionado principalmente pelo consumo alimentar inadequado e pelo sedentarismo. Salienta-se a importância da identificação precoce de agravos nutricionais em crianças e adolescentes fenilcetonúricos, a fim de prevenir doenças crônicas associadas e promover a saúde, com incentivo à manutenção de hábitos alimentares saudáveis e à prática regular de exercícios fí...

Background/Aim: The study of physical growth variables in terms of chronological age and biological maturation may provide a common reference point to reflect on the occurrence of body dimensions in and between individuals. The objectives of this study were as follows: (a) verify if the observed gender differences in the variables of physical growth by chronological age are confounded by physical maturation, (b) compare physical growth patterns with the reference of the Centers for Disease Control and Prevention (CDC)-2012, and (c) develop regional curves to assess physical growth in terms of biological maturation. Methods: Researchers studied 3,674 children and adolescents. Weight, standing height, and sitting height were measured. Biological maturation was determined by using the age of peak velocity growth. Body mass index (BMI) was calculated. Growth variables were compared with the CDC-2012 reference. Percentiles were calculated by the LMS method. The students differed in weight and BMI when compared to the reference individuals. The differences in weight, standing height, and BMI between both genders are more pronounced when they are aligned with biological age rather than chronological age. Conclusion: Weight and BMI differ from the reference. Furthermore, the assessment of the physical growth trajectory should be analyzed in terms of biological maturation. The proposed regional curves may be used in and applied to clinical and epidemiological contexts.
