Abstract

to assess the severity of obesity in children and adolescents through the presence of comorbidities and the potential indication of bariatric surgery. we conducted a cross-sectional study with clinical and laboratory data of the first consultation of patients at the childhood obesity clinic at a tertiary hospital from 2005 to 2013. We divided the patients into groups with or without potential indication for surgery, and recorded age, gender, birth weight, age of obesity onset, BMI Z score, presence of acanthosis nigricans, blood pressure, total cholesterol and fractions, triglycerides, blood glucose and fasting insulin, HOMA1-IR, CRP and ESR. The group with potential indication for surgery included: BMI > 40 or between 35-40 with comorbidities (Triglycerides >130mg/dl, glucose levels >100mg/dl, HOMA1-IR >3.16, Total Cholesterol >200mg/dl, LDL >130mg/dl and HDL <45mg/dl), regardless of age, epiphysis consolidation and previous treatment. of the 296 patients included in the study, 282 (95.3%) were younger than 16 years. The most frequent change was the HDL (63.2%), followed by HOMA1-IR (37.5%). Of the group of 66 patients with potential indication for surgery (22.3%), only ten (15.1%) had more than 16 years. Acanthosis nigricans, the average HOMA1-IR, insulin, CRP, ESR, age, BMI Z score and systolic and diastolic blood pressure were significant in the group with potential surgical indication. bariatric surgery might be indicated by BMI and comorbidities in children and adolescents under 16 years. avaliar a gravidade da obesidade em crianças e adolescentes pela presença de comorbidades e pela potencial indicação de cirurgia bariátrica. estudo transversal com dados clínicos e laboratoriais da primeira consulta de pacientes do ambulatório de obesidade infantil em um hospital terciário no período de 2005 a 2013. Os pacientes foram divididos em grupos com ou sem potencial indicação cirúrgica, e associados com idade, sexo, peso de nascimento, idade de início da obesidade, escore z de IMC, presença de acantose nigricans, pressão arterial, colesterol total e frações, triglicérides, glicemia e insulina de jejum, HOMA1-IR, PCR e VHS. O grupo com potencial indicação cirúrgica incluiu: IMC >40 ou IMC entre 35-40 com comorbidades (Triglicérides >130mg/dl, Glicemia >100mg/dl, HOMA1-IR >3,16, Colesterol total >200mg/dl, LDL >130mg/dl e HDL <45mg/dl), independente da idade, consolidação das epífises e tratamento prévio. de 296 pacientes incluídos no estudo, 282 (95,3%) tinham menos de 16 anos. A alteração mais frequente foi a do HDL (63,2%), seguido do HOMA1-IR (37,5%). Do grupo de 66 pacientes com potencial indicação cirúrgica (22,3%), apenas dez (15,1%) tinham mais de 16 anos. Acantose nigricans, as médias de HOMA1-IR, insulina, PCR, VHS, idade, escore z de IMC e pressões sistólica e diastólica foram significantes no grupo com potencial indicação cirúrgica. os resultados sugerem que a cirurgia bariátrica, poderia estar indicada pelo IMC e presença de comorbidades, em crianças e adolescentes com menos de 16 anos.

Highlights

  • In the last 50 years, there have been changes in the profile of health problems in children and adolescents and, in this context, obesity has emerged as a pandemic disease of high prevalence and morbidity[1]

  • This study aims to assess the severity of obesity in children and adolescents referred to the outpatient clinic of a tertiary hospital, through the presence of comorbidities and the potential for bariatric surgery indication

  • We found that the average age (p=0.006), the body mass index (BMI) Z score (p=0.005) and the systolic and diastolic blood pressure (BP) measurements (p=0.000) were significant in the group with potential surgical indication, as well as the presence of acanthosis nigricans (p=0.006)

Summary

Introduction

In the last 50 years, there have been changes in the profile of health problems in children and adolescents and, in this context, obesity has emerged as a pandemic disease of high prevalence and morbidity[1]. After nearly three decades of alarming increase in its prevalence in the world, the latest studies in developed countries show a trend of stabilization, but with worsening severity[2,3,4]. In some developing communities, where we observe the coexistence of growth delay and obesity, it is believed that this population is changing from malnutrition to excess weight, without going through eutrophy[5]. The latest data show increased prevalence in all age groups, a little lower in children under five years, and in both genders[6,7]
