MULT: An allometric body mass index (ABMI) reference to assess nutritional status of multiethnic children and adolescents.

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 Kingdom, Ethiopia, India, Peru, Vietnam, Portugal, and Brazil. The M, S, and L curves of the MULT ABMI reference were compared with the curves of the MULT, World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), International Obesity Task Force (IOTF), and Dutch Growth Study (DUTCH).

Reference growth curves of anthropometric markers in Brazilian children and adolescents aged 7-14 years from southern Brazil.

Reference growth curves are viable tools for monitoring somatic growth. Therefore, the objective of this study was to develop reference growth curves for body mass, height, body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR) in Brazilian children and adolescents aged 7-14 years. The reference growth curves were constructed from a cross-sectional panel study using data from four surveys conducted in 2002, 2007, 2012/2013 and 2018/2019, with 9675 children and adolescents aged 7-14 years, of both sexes from Florianopolis, Southern Brazil.

[The quality of the anthropometric data on children under five years of age in information systems in the State of São Paulo, Brazil].

This paper involves the analysis of the quality of anthropometric data on children under five years of age in two information systems in the State of São Paulo. The sample included 2,117,108 children from the Food and Nutrition Surveillance System (SISVAN), and 748,551 from the State Milk Project (VIVALEITE). Initially, we evaluated the frequency of missing values and others outside the equipment spectrum and calculated the digit-to-weight preference index.

[Quality of anthropometric data of children under 5 years in the Brazilian National Food and Nutrition Surveillance System, 2008-2020].

The planning, monitoring, and evaluation of food and nutrition actions depend on reliable estimates based on adequate anthropometric data. The study aimed to analyze the quality of anthropometric data of children aged under 5 years in the Brazilian National Food and Nutrition Surveillance System (SISVAN) from 2008 to 2020. The sample comprised 23,453,620 children aged under 5 years.

Frequency of anthropometric implausible values estimated from different methodologies: a systematic review and meta-analysis.

Context: Poor anthropometric data quality affect the prevalence of malnutrition and could harm public policy planning.

Objective: This systematic review and meta-analysis was designed to identify different methods to evaluate and clean anthropometric data, and to calculate the frequency of implausible values for weight and height obtained from these methodologies.

Data Sources: Studies about anthropometric data quality and/or anthropometric data cleaning were searched for in the MEDLINE, LILACS, SciELO, Embase, Scopus, Web of Science, and Google Scholar databases in October 2020 and updated in January 2023.

The scope of this work was to assess the association between the duration of remote work and a positive diagnosis of COVID-19 among individuals employed in Brazil. Data from the PNAD COVID19 (2020) survey were consulted. The variables in the work situation described included: absence from work due to physical distancing, work segment (work sector and formality: formal or informal private, military, statutory civil servant, CLT public sector, informal public sector, employer, self-employed/unpaid worker) and duration of remote work (no remote work for 1-2 months, 3-4 months, 5-7 months, respectively).

MULT: A new BMI reference to assess nutritional status of multi-ethnic children and adolescents.

Objectives: To develop a new Body Mass Index (BMI) reference (MULT) based on longitudinal data of multi-ethnic populations and to compare it to international BMI references.

Undernutrition and obesity trends in Brazilian adults from 1975 to 2019 and its associated factors.

Nutritional status has evolved in a dual trend worldwide: underweight has become a minor or local issue while overweight or obesity has risen to play a major role in the global burden of disease. In 2014, Brazil was ranked as the third country with the highest absolute number of obese men. Our aim was to estimate trends of underweight and obesity among Brazilian adults using a comprehensive set of surveys from 1974 to 2019.

Design: This is a cross-sectional study with data from Demographic and Health Surveys programme conducted in Bolivia, Brazil, Colombia, Peru and the Dominican Republic between 1990 and 2013. The median duration of breast-feeding was estimated by survival analysis.

Body phenotypes and sexual maturation in Brazilian and US adolescents: evidence for a change in BMI category.

Objective: Our study aimed to describe body phenotypes (BP) estimated by multivariate analysis and their association with body mass.

Design: BP were defined based on demographic variables, anthropometric data (body mass, height, skinfolds and circumferences), body composition (phase angle measured by bioelectrical impedance analysis), biochemical parameters (TAG, glucose, total cholesterol ratio/LDL, Hb and sexual maturation (pubic hair and breasts or gonads). ANOVA was performed to verify the differences between skin colour and the stages of pubertal development, BP, body composition, anthropometric and biochemical variables.

[Intra-family and school violence scale using the Item Response Theory].

Violence is a global public health problem and may be of a physical, sexual, or psychological nature, or due to negligence. In order to evaluate this situation, instruments are needed that can assess this widely diverse scenario. The scope of this research was to develop a scale to evaluate intra-family and school violence.

[Body phenotypes in adolescence: is it necessary to adjust body mass index according to sexual maturation stages?].

This study aimed to analyze the effect of sexual maturation on body phenotypes, based on multivariate analysis of adolescents' nutritional status. This was a cross-sectional study with a sample of 833 adolescent schoolchildren 10 to 15 years of age, selected by complex sampling in Piracicaba, São Paulo State, Brazil. Body phenotypes were defined by principal components analysis (PCA), based on age, anthropometric data (body mass, height, skinfolds, and waist circumference), body composition (phase angle measured by bioelectrical impedance), and biochemical parameters (triglycerides, glucose, total cholesterol/LDL ratio, hemoglobin).
