ABSTRACT Obesity is a chronic disease associated with impaired physical and mental health. A widespread view in the treatment of obesity is that the goal is to normalize the individual's body mass index (BMI). However, a modest weight loss (usually above 5%) is already associated with clinical improvement, while weight losses of 10%-15% bring even further benefits, independent from the final BMI. The percentage of weight reduction is accepted as a treatment goal since a greater decrease in weight is frequently difficult to achieve due to metabolic adaptation along with environmental and lifestyle factors. In this document, the Brazilian Society of Endocrinology and Metabolism (SBEM) and the Brazilian Society for the Study of Obesity and Metabolic Syndrome (ABESO) propose a new obesity classification based on the maximum weight attained in life (MWAL). In this classification, individuals losing a specific proportion of weight are classified as having “reduced” or “controlled” obesity. This simple classification – which is not intended to replace others but to serve as an adjuvant tool – could help disseminate the concept of clinical benefits derived from modest weight loss, allowing individuals with obesity and their health care professionals to focus on strategies for weight maintenance instead of further weight reduction. In future studies, this proposed classification can also be an important tool to evaluate possible differences in therapeutic outcomes between individuals with similar BMIs but different weight trajectories.

O número de portadores de diabetes melito tipo 1 (DM1) está aumentando globalmente, entretanto, a maior parte dos pacientes apresenta controle glicêmico insatisfatório. Esta revisão na literatura foi realizada com três questões de pesquisa: Quais as recomendações e diretrizes de educação em diabetes existentes? Existem evidências para recomendar a adaptação de determinado programa segundo a faixa etária dos pacientes? Os programas de educação são efetivos na melhora dos níveis de HbA1c? Foram revisados 40 artigos, publicados entre 2000 e 2007, sobre educação em DM1 em crianças, adolescentes, adultos e usuários de bomba de infusão contínua de insulina, além de incluir o resumo das diretrizes da IDF, da ADA, da SBD, da AADE, do IDC, e outras peculiaridades para o contexto de saúde pública e privada. O portador de diabetes e sua família devem ser treinados a fazer decisões efetivas de autocuidado em sua rotina diária. O aprimoramento do paciente no automanejo aproxima o valor da HbA1c ao adequado para sua faixa etária. A educação individual e a em grupo apresentam equivalência na melhora do controle metabólico. Existe uma correlação positiva entre o tempo de educação e o controle da glicemia.

Type 1 diabetes incidence has been increasing worldwide, however the vast majority of patients do not have a good glycaemic control. This review focuses on diabetes educational programs designed for children, young adults and their families, as well as regular pump users educational tips, collected from papers published between 2000 and 2007. A comprehensive review of the literature has identified 40 articles describing the methods and the evaluation of diabetes self-management education interventions. Three research questions are posed. First: what are the recommendations and standards for diabetes self-management education from the different diabetes institutions/associations? Second: is there sufficient evidence to recommend any adaptation of any particular program? And third: Are the educational programs effective in lowering glycated haemoglobin (HbA1c)? The patient and his family should be instructed and trained to take appropriate decisions for diabetes management regarding their daily care. Diabetes self-management education improves glicaemic control (both in an individual basis as well as in groups) in such a way that the longer the education training in diabetes the better is the effect on glycaemic control is.
