Indicadores antropométricos para identificar síndrome metabólica e fenótipo cintura hipertrigliceridêmica: uma comparação entre as três fases da adolescência

Abstract

OBJECTIVE: To determine the prevalence of metabolic syndrome (MS) and the hypertriglyceridemic waist phenotype (HW) in a representative adolescent sample; as well as to establish which anthropometric indicator better identifies MS and HW, according to gender and adolescent age. METHODS: This cross sectional study had the participation of 800 adolescents (414 girls) from 10-19 years old. Anthropometric indicators (body mass index, waist perimeter, waist/stature ratio, waist/hip ratio, and central/peripheral skinfolds) were determined by standard protocols. For diagnosis of MS, the criteria proposed by de Ferranti et al. (2004) were used. HW was defined by the simultaneous presence of increased waist perimeter (>75th percentile for age and sex) and high triglycerides (>100 mg/dL). The ability of anthropometric indicators was evaluated by Receiver Operating Characteristic curve. RESULTS: The prevalence of MS was identical to HW (6.4%), without differences between genders and the adolescence phases. The waist perimeter showed higher area under the curve for the diagnosis of MS, except for boys with 17-19 years old, for whom the waist/stature ratio exhibited better performance. For diagnosing HW, waist perimeter also showed higher area under the curve, except for boys in initial and final phases, in which the waist/stature ratio obtained larger area under the curve. The central/peripheral skinfolds had the lowest area under the curve for the presence of both MS and HW phenotype. CONCLUSIONS: The waist perimeter and the waist/stature showed a better performance to identify MS and HW in both genders and in all three phases of adolescence.

Development of a Computational Model to Predict Excess Body Fat in Adolescents through Low Cost Variables

“…Adolescence is a stage of physical and intellectual changes [2,59] where there is intense body growth that interferes with the accumulation and distribution of body fat [44]. It is therefore seen as one of the most critical periods for the development of obesity [17].…”

“…In contrast to the anthropometric indicators, waist circumference is already a consolidated index for the analysis of central fat and cardiovascular risk [37,38,39]. In addition, the circumference of the arm, hip, and calf are used to assess the nutritional status and population health [22,23,25,40,41,42,43,44,45,46]. Other factors were considered, such as low cost, reproducibility, and accessibility to the entry attributes, especially if the method is used in remote places.…”

Hypertriglyceridemic Waist and Associated Factors in Children and Adolescents With Type 1 Diabetes Mellitus

“…In a cohort with students from a city in Bahia involving children and adolescents, Costa et al 12 found a prevalence of 10.6%. In studies conducted by Pereira et al 11 and Conceição-Machado et al, 8 the phenotype was prevalent only in adolescents, with 6.4 and 7.2%, respectively. These differences in prevalence can be explained by the different cut-off points adopted to classify WC and TG, and subsequent definition of the HTGW phenotype.…”

“…9 In 2000, Lemieux et al developed one of the first studies involving HTGW with a sample of Canadian male adults, finding high agreement between this index and the atherogenic metabolic triad. 10 Nevertheless, despite the lack of studies involving individuals with T1DM nationwide, the literature has presented research with several populations, including children 11 and adolescents, 8,12 indicating a scenario in which CVDs represent the main cause of morbidity and mortality, affecting increasingly younger individuals and significantly reducing productive life. Thus, this study aimed to evaluate the frequency of the HTGW phenotype and its associated factors in children and adolescents with T1DM.…”

Conhecimento de adolescentes acerca dos benefícios do exercício físico para a saúde mental

“…It is conceptualized as a phase of several structural and behavioral transformations, especially in the psychic, physical, biological and social aspects 2 . For statistical data, we can divide it into three stages: initial adolescence (10-13 years), intermediate adolescence (14-16 years) and final adolescence (17)(18)(19) years) 3 .…”
