RESUMEN
OBJECTIVE: To assess the repercussions of SARS-CoV-2 infection (suspected or confirmed) and the context of the pandemic on the birth route and humanized assistance during childbirth. METHOD: Cross-sectional epidemiological study, nested within a cohort and comparative with the research "Birth in Belo Horizonte: Survey on Childbirth and Delivery".The medical records of three reference maternity hospitals in Belo Horizonte were assessed, with a final sample of 1,682 pregnant women, in the months of May, June and July 2020. A descriptive analysis was carried out, with absolute and relative frequency, and a comparative one, with a Pearson's chi-square test. RESULTS: It was observed that 2.02% of pregnant women were infected with SARS-CoV-2.Before the pandemic, out of a total of 390 pregnant women, 74.10% gave birth vaginally.During a pandemic, among infected women, 51.61% gave birth via cesarean section and 48,39% via vaginal delivery;among uninfected, 26.99% cesarean sections and 73.01% vaginaldeliveries. CONCLUSION: There was an increase in the percentage of cesarean sections and a possible influence of the pandemic on the rates of indication of cesarean sections at the time of admission to the maternity ward.

RESUMEN
Abstract Objectives: to investigate the association between the Índice de Qualidade da Dieta Adaptado para Gestantes (IQDAG) (Quality of Diet Index Adapted for Pregnant Women) with food consumption, lifestyle and health information. Methods: cross-sectional study with 110 pregnant women assisted at a public health service. Sociodemographic, nutritional and health data were collected from medical records. Food consumption was investigated through the usual intake, for a nutritional analysis, DietPro® program version 6.1 was used. Quality ofdiet was assessed using the IQDAG. Multinomial logistic regression was used to investigate an association between food consumption and IQDAG. Results: the average total score of the IQDAG was 61.3 (±26.1), this is the best quality of the diet. After adjusting for age, schooling and physical activity, the highest consumption of vitamin A (OR=1.04; CI95% = 1.02-1.07) and B2 (OR=2.63; CI95% = 1.19-5.70) was associated with a greater chance of having a better quality of diet (3rdtertile of the IQDAG). Conclusions: pregnant women with better quality of diet had higher intakes of vitamins A and B2. However, other population-based studies are suggested to more broadly in verify its association with food consumption and its ability to identify adherence to nutritional recommendations.
Resumo Objetivos: investigar a associação entre o Índice de Qualidade da Dieta Adaptado para Gestantes (IQDAG) com o consumo alimentar e hábitos de vida e informações de saúde. Métodos: estudo transversal com 110 gestantes atendidas em um serviço público de saúde. Os dados sociodemográficos, nutricionais e de saúde foram coletados a partir dos prontuários de atendimento. O consumo alimentar foi investigado por meio do recordatório de ingestão habitual, para a análise nutricional foi utilizado o Programa DietPro® versão 6.1. A qualidade da dieta foi avaliada utilizando o IQDAG. A regressão logística multinomial foi usada para investigar a associação entre o consumo alimentar e IQDAG. Resultados: a média da pontuação total do IQDAG foi 61,3 (±26,1), isto é uma melhor qualidade da dieta. Após ajuste por idade, escolaridade e atividade física, o maior consumo de vitamina A (OR=1,04; IC95%= 1,02-1,07) e B2 (OR= 2,63; IC95%= 1,19-5,70) esteve associado a maior chance da gestante apresentar uma melhor qualidade da dieta (3º tercil do IQDAG). Conclusões: gestantes com melhor qualidade da dieta tiveram maior ingestão das vitaminas A e B2. Entretanto, sugere-se outros estudos de base populacional para verificar de forma mais ampla sua associação com o consumo alimentar e sua capacidade de identificar a adesão as recomendações nutricionais.

A new phenotype of obesity has been studied: normal-weight obesity (NWO), which describes individuals with normal-weight by BMI and excess body fat. Despite normal-weight, individuals with NWO have a higher cardiometabolic risk. There is still a gap in the literature on the subject, especially in adolescents, as studies with this population are scarce. This study aims to investigate the sociodemographic factors, family history of chronic non-communicable diseases, body perception, lifestyle and food consumption associated with NWO in adolescents. This is a cross-sectional study, with 506 normal-weight adolescents aged 1019 years, of both sexes. Weight and height were obtained, and BMI/age was calculated. Body fat analysis was performed using dual-energy X-ray absorptiometry. Sociodemographic data, level of physical activity, food consumption, body self-perception and lifestyle habits were also obtained. Logistic regression with hierarchical approach was used to analyse the associations. The odds of NWO are greater with age (OR = 1·14; 95 % CI = 1·04, 1·26), lower in male adolescents (OR = 0·21; 95 % CI = 0·11, 0·41) and higher in those with a history of familial dyslipidemia (OR = 1·81; 95 % CI = 1·01, 3·28). Adolescents satisfied with their body (OR = 0·30; 95 % CI 0·16, 0·56) and physically active (OR = 0·44; 95 % CI = 0·24, 0·81) have a lower odds of NWO, compared with the others. In addition, it was observed that the odds of NWO is greater among adolescents who use sweeteners (sugar substitutes) (OR = 3·84; 95 % CI = 1·70, 8·65). The factors associated with NWO were female sex, older age, positive family history of dyslipidemia, lower body satisfaction, lower level of physical activity and greater use of sweeteners.
RESUMEN
BACKGROUND: Normal weight obesity (NWO), which is defined by the excess of body fat in normal weight individuals, has been neglected among adolescents, due to their normal weight and young age. Few studies were carried out on the topic with adolescents. OBJECTIVE: To analyze whether the NWO is associated with cardiometabolic risk factors in adolescents. SUBJECTS/METHODS: Cross-sectional study, with 506 normal weight adolescents aged 10-19 years, selected in schools in Brazil. Weight, height, waist circumference (WC) and neck circumference were obtained and the body mass index (BMI) and waist/height ratio (WHR) were calculated. Body composition analysis was performed using dual-energy X-ray absorptiometry. The clinical evaluation included lipid and glycid profile, platelets, leukocytes, lymphocytes, monocytes, uric acid and blood pressure, as well as the presence of metabolic syndrome (MS) and its components. NWO was defined by the presence of normal weight, according to BMI for age, and excess body fat (≥25% and ≥30% in males and females, respectively). Logistic regression models were used to analyze associations between normal weight adolescents with and without the NWO phenotype. RESULTS: NWO associated positively with abdominal obesity, analyzed through WC (OR = 1.36;95%CI = 1.27-1.47), WHR (OR = 25.89;95%CI = 10.43-64.26) and android fat (OR = 1.49;95%CI = 1.36-1.63); insulin resistance (OR = 4.09;95%CI = 1.72-9.70), hyperinsulinemia (OR = 3.83;95%CI = 1.50-9.76) and the highest values of the triglycerides-glycemia index (OR = 4.28;95%CI = 1.21-15.08); uric acid (OR = 1.81;95%CI = 1.29-2.55), as well as the changes in LDL (OR = 3.39;95%CI = 1.47-7.81), total cholesterol (OR = 2.77;95%CI = 1.22-6.29), and in at least one (OR = 1.87;95%CI = 1.04-3.37) or two (OR = 6.61;95%CI = 1.45-30.19) components of MS. CONCLUSION: NWO is associated with the presence of cardiometabolic risk factors in adolescents.

We aimed to investigate the anthropometric and body composition parameters associated with the metabolically obese normal-weight (MONW) phenotype. This cross-sectional study was conducted with 506 adolescents in Brazil (aged 10-19 y). The MONW phenotype was defined as normal-weight, according to BMI/age, and at least one metabolic alteration. Anthropometric measurements were obtained and the DEXA was used for body composition analysis. Crude and adjusted Poisson regression models with robust variance were used to estimate the associations. The phenotype was positively associated with waist circumference (male: prevalence ratio (PR) = 1·05; 95% CI 1·01, 1·09; female: PR = 1·06; 95% CI 1·02, 1·09), waist:height ratio (male: PR = 1·26; 95% CI 1·07, 1·49; female: PR = 1·29; 95% CI 1·07, 1·56) and android:gynoid fat ratio (male: PR = 1·25; 95% CI 1·03, 1·51; female: PR = 1·39; 95% CI 1·20, 1·62), in both sexes. Furthermore, there was a positive association of phenotype with waist:hip ratio (PR = 1·32; 95% CI 1·06, 1·65) and trunk:arm fat ratio (PR = 1·13; 95% CI 1·02, 1·24) only in males and with trunk:leg fat ratio (PR = 2·84; 95% CI 1·46, 5·53), BAIp (PR = 1·06; 95% CI 1·01, 1·12), fat mass index (PR = 1·24; 95% CI 1·10, 1·41) and regional indices of metabolic load and capacity (PR = 1·29; 95% CI 1·09, 1·53), in females. Anthropometric and body composition parameters indicative of central and total fat are associated with the MONW phenotype.

Abstract Objectives: to investigate the relation between maternal overweight and child's anthropometric indices, identifying the interaction with the child's age. Methods: a cross-sectional study with mothers and their children under 2 years old. The mothers' body mass index (BMI), waist-to-hip ratio and waist-to-height ratio was calculated. In children, we calculated height/age (H/A), body mass index/age (BMI/A), weight/height (W/H) and weight/age (W/A) indices. The means of the anthropometric indices of children with excess weight and maternal cardiometabolic risk were compared. Mothers and children's anthropometric indices were correlated. Linear regression models were proposed. We investigated the child's age interaction with anthropometric variables of the dyad. Results: the means of BMI/A and W/H were higher in children of overweight mothers and the means of BMI/A, W/H and W/A were higher when mothers had increased risk for cardiometabolic diseases. There was an association of maternal weight and height with the W/A index; maternal BMI with W/H; maternal height with H/A; maternal weight, BMI and waist circumference with BMI/A. The children's age did not interact with the assessed parameters. Conclusion: children under 2 years of age, whose mothers are overweight, tend to show changes in weight, regardless of age.
Resumo Objetivos: investigar a relação do excesso de peso materno com índices antropométricosinfantis, identificando a interação da idade da criança. Métodos: estudo transversal com mães e seus filhos menores de 2 anos. Calculou-se o índice de massa corporal (IMC), relação cintura quadril e relação cintura estaturadas mães. Nas crianças, calculou-se os índices estatura/idade (E/I), índice de massa corporal/idade (IMC/I), peso/estatura (P/E) e peso/idade (P/I). Comparou-se as médias dos índices antropométricos das crianças com excesso de peso e risco cardiometabólico materno. Correlacionou-se índices antropométricos infantis e maternos. Modelos de regressão linear foram propostos. Foi investigada interação da idade da criança com variáveis antropométricas da díade. Resultados: as médias do IMC/I e P/E foram maiores em filhos de mães com excesso de peso e as médias do IMC/I, P/E e P/I foram maiores quando mães apresentaram risco aumentado para doenças cardiometabólicas. Verificou-se associação do peso e estatura materna com o índice P/I; do IMC materno com P/E; da estatura materna com E/I; do peso, IMC e perímetro da cintura materna com IMC/I. A idade das crianças não interagiu com os parâmetros avaliados. Conclusão: crianças menores de 2 anos, cujas mães têm excesso de peso, tendem a apresentar alteração no peso, independente da idade.

Overweight is increasing in the adolescent population and became a public health problem in the world. This study aimed to identify the body adiposity indices (BAI) with the best capacity to predict excess fat tissue and propose cut-off points for them, according to sex and adolescence period. This is a cross-sectional study. We calculated BMI, conicity index (CI), BAI, body roundness index (BRI), waist:height ratio (WtHR) and waist:hip ratio. Predictive capacity and cut-off points of adiposity indices were established by ROC (receiver operating characteristic) curves. We determined AUC-ROC and CI, stratified by sex and adolescence period. The best index to identify excess body fat in 10-13-year-old female adolescents was the WtHR (AUC = 0·92), like the BAI in girls aged from 14 to 16 years old (AUC = 0·87) and 17 to 19 years old (AUC = 0·80). In male adolescents aged from 10 to 13 years old and 14 to 16 years old, the best index was the WtHR (AUC = 0·93 and AUC = 0·8, respectively), like the BAI in boys aged from 17 to 19 years old (AUC = 0·95). The use of indices with specific cut-off points for each period of adolescence and according to sex is important for the reliable diagnosis of excess body fat. It is advisable to use indices together to obtain a more accurate assessment. Thus, the WtHR and BAI are reproducible and reliable, with high sensitivity and specificity values, and can be used together with the BMI.

AIM: To propose an equation to estimate height and evaluate it's performance in the composition of adiposity indicators in community-dwelling older adults in Brazil. METHODS: It is a cross-sectional study with 675 community-dwelling older adults (≥60 anos). Interviews and anthropometric measurements were taken at subjects' homes. Body mass index (BMI), body adiposity index (BAI), waist height ratio (WHR), and conicity index (CI) were calculated. The height estimation equation was obtained by multiple linear regression. Concordance between height and the indicators measured and estimated was evaluated by the intraclass correlation coefficient (ICC) and Cohen's Kappa and Weighted Kappa indexes. Concordance was also evaluated by the Bland and Altman graphical approach. RESULTS: Equations of height estimation composed of knee height, sex, and schooling were proposed and stratified by age group (60-74 years and ≥75 years). In both age groups, almost perfect agreement (ICC ≥ 0.915 and Kappa ≥0.81) was found between height and adiposity indicators estimated and measured. CONCLUSION: The equation proposed is suitable to estimate height of the older adults, and can be a valuable tool for the evaluation of the nutritional status of Brazilian older adults in the community.

INTRODUCTION: Skeletal muscle is the primary site of glucose uptake and its reduction would increase insulin resistance, which is a determinant factor for diseases such as type 2 diabetes mellitus, hypertension, and metabolic syndrome. However, the role of low skeletal muscle mass as a risk factor for metabolic syndrome and its association with cardiometabolic risk is still uncertain. We aimed to investigate the association between muscle mass (determined by different skeletal mass indices) and metabolic syndrome in Brazilian adults. METHODOLOGY: We conducted a cross-sectional population-based study with 689 adults of both sexes aged between 20 and 59 years. Data were collected through questionnaires and assessment of body composition through dual-energy X-ray absorptiometry and anthropometric, clinical, and biochemical measurements. RESULTS: Older individuals, obese and those with metabolic syndrome predominated in the highest tertile of skeletal mass index adjusted by height (SMIheight), whereas using skeletal mass index adjusted by weight (SMIweight) and skeletal mass index adjusted by body mass index (SMIBMI) these individuals were the majority in the lowest tertile of these indices. In men and women, the adjusted logistic regression model revealed that the highest tertile of SMIweight (odds ratio [OR]: 0.06; 95% confidence interval [CI]: 0.02-0.21 and OR: 0.27, 95% CI: 0.10-0.74) and SMIBMI (OR: 0.14, 95% CI: 0.05-0.37 and OR: 0.34, 95% CI: 0.12-0.94) were negatively associated with metabolic syndrome. On the other hand, the highest tertile of SMIheight was positively associated with metabolic syndrome in both sexes (OR: 4.17, 95% CI: 1.80-9.66 and OR: 6.15, 95% CI: 2.31-16.37, respectively in men and women). CONCLUSION: In adults, the muscle mass assessed from the skeletal mass index adjusted for body weight and body mass index is inversely associated with metabolic syndrome in both sexes.

Muscle mass may play an important role in the metabolic profile of individuals with or without excess weight. Metabolic phenotypes classify individuals as healthy or unhealthy based on certain metabolic conditions. We investigated the association between skeletal mass indices (SMI) and the metabolically unhealthy phenotype in normal-weight and overweight/obese adults. A total of 660 adults aged 20 to 59 years were assessed by a population-based cross-sectional study. Muscle mass of the limbs or appendicular lean mass (ALM) adjusted for weight (SMIweight) and BMI (SMIBMI) was used to evaluate SMI. Logistic regression was employed to estimate the association between SMIweight, SMIBMI and metabolic phenotypes of normal-weight and overweight/obese individuals. Metabolically unhealthy individuals were older in both sexes. Metabolically unhealthy men had lower SMI values and higher fat percentage than metabolically healthy men. SMIweight was inversely associated with the metabolically unhealthy phenotype, both in normal-weight men (OR 0·49, 95 % CI 0·24, 0·99, P = 0·04) and in overweight/obese men (OR 0·32, 95 % CI 0·16, 0·64, P = 0·001). SMIBMI was inversely associated with the metabolically unhealthy phenotype in overweight/obese men (OR 0·36, 95 % CI 0·18, 0·72, P = 0·004), but not in normal-weight men (OR 0·70, 95 % CI 0·34, 1·43, P = 0·33). Among women, SMI showed no significant association with the phenotypes. In conclusion, the SMI are inversely associated with the metabolically unhealthy phenotype in men, especially among overweight/obese men.

OBJECTIVE: To analyse the presence of cardiometabolic risk factors in adolescents with normal-weight obesity (NWO), as well as to investigate health behaviours related to the phenotype. DESIGN: The study was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines and the bibliographic search was carried out in the PubMed, Scielo and ScienceDirect databases. SETTING: School, university and population. PARTICIPANTS: Adolescents between 10 and 19 years old. RESULTS: A total of eight papers were included. Most studies have found a relationship between NWO and the presence of cardiometabolic risk factors, such as high waist circumference, unfavourable lipid and glycid profile. As for health behaviours, three of the eight studies included evaluated eating habits; however, the results were not conclusive. In addition, four studies analysed the practice of physical activity or physical fitness, which was lower in NWO. CONCLUSIONS: The available evidence indicates that NWO is related to the early development of cardiometabolic changes, physical inactivity and less physical fitness in adolescents. The results also reveal the importance of early detection of the phenotype, as well as the need for further research on the associated factors to prevent future diseases.

O objetivo desta pesquisa foi descrever e relacionar classificação operacional, vacinação com BCG e gênero entre casos novos de hanseníase na Colônia Padre Damião, município de Ubá, Minas Gerais, de 2000 a 2016. Os dados foram coletados a partir de fichas de notificação e entrevistas, totalizando 43 casos novos pesquisados. Gênero feminino, forma multibacilar e vacinados predominaram na análise descritiva. Além disso, observou-se diminuição na porcentagem de casos multibacilares em indivíduos com uma ou duas cicatrizes de BCG em comparação com os sem cicatriz. Em mulheres com uma cicatriz, comparadas com as sem cicatriz, ocorreu menor porcentagem de casos multibacilares. Nos homens, casos paucibacilares foram encontrados somente em indivíduos com duas cicatrizes. Portanto, a vacina BCG administrada em 1 dose está relacionada com proteção contra a forma multibacilar em mulheres. Em homens, a segunda dose é necessária para se proteger contra essa forma clínica.

The descriptive analysis indicated the predominance of the female gender, multibacillary form, and vaccinated individuals. Moreover, there was a decrease in the percentage of multibacillary cases in individuals with one or two BCG scars compared to those without scarring. In women with a scar, compared to those without a scar, there was a lower percentage of multibacillary cases. In men, paucibacillary cases were found only in individuals with two scars. Therefore, the BCG vaccine given in 1 dose is related to protection against the multibacillary form in women. In men, the second dose is required for protection against this clinical form.
RESUMEN
We analysed the coverage trend of the evaluation of the nutritional status of users of public health services registered in the Food and Nutrition Surveillance System (SISVAN) between 2008 and 2017 in seven municipalities and verified the association of the coverage trend with the socio-economic, demographic and organisational aspects of health system variables. It is an ecological time-series study performed with secondary data extracted from health information systems. Descriptive statistics, linear regression model and repeated measures analysis were performed. The coverage of evaluation of nutritional status was low over the period. Five municipalities showed a tendency to increase coverage, although small, while two remained stable. The highest annual variation in coverage increase was concentrated in the group of pregnant women and the lowest in adolescents and older adults. There was a downward trend in follow-ups from the Bolsa Family Programme and a trend towards increased follow-ups from SUS Primary Care (e-SUS AB). SISVAN coverage was positively associated with the proportion of rural population (P ≤ 0·001) and coverage of community health agents (P < 0·001); and negatively associated with total population (P < 0·001), demographic density (P = 0·006) and gross domestic product per capita (P = 0·008). Despite the tendency to increase coverage in some municipalities, SISVAN still presents low coverage of nutritional status assessment, which compromises population monitoring. Knowing the factors that influence the coverage can subsidise the elaboration of strategies for its expansion.

ABSTRACT Objective To establish percentile curves for measures and indices of body composition by age and sex and compare them with data from other ethnic groups. Subjects and methods Cross-sectional, population-based study with adults aged 20-59 years (n = 689). Percentile curves adjusted by a third degree polynomial function were constructed for skeletal mass index (SMI), fat mass index, body fat, and load-capacity metabolic indices (LCMI) based on dual-energy X-ray absorptiometry (DXA). Results SMIweight and SMIBMI showed decline from the third decade of life in both sexes, whereas SMIheight was not able to identify lean mass loss over the ages studied. There was a slight drop at the end of the fifth decade (50-59 years) in men. Among Americans and Chinese, the 50th percentile curve of SMIheight showed an earlier decline. The estimates of adiposity and LCMI curves peaked between 40-49 years and Americans and Chinese maintained an upward curve throughout adulthood. Conclusion The data and curves showed that the SMI adjusted for BMI and body weight were more adequate in detecting the decline of lean mass in adults due to aging. In contrast, SMIheight had a positive correlation with age and its curve increased throughout the evaluated age groups. The results contribute to the evaluation to the nutritional status of adults and to the prevention and treatment of outcomes related to adiposity and deficit lean mass.

OBJECTIVE: To identify the dietary patterns of children aged 4-7 years and verify their association with sociodemographic characteristics, lifestyle habits and exclusive breast-feeding (EBF). DESIGN: A cross-sectional study nested within a cohort, performed with Brazilian children aged 4-7 years. The children were re-evaluated at age 4 to 7 years and food patterns were identified a posteriori through principal component analysis. The predictive variables were related to socio-economic characteristics, lifestyle habits and duration of EBF. SETTING: Viçosa, Minas Gerais, Brazil.ParticipantsRepresentative sample of 403 children followed up by the Lactation Support Program from the Extension Program of the Universidade Federal de Viçosa during the first 6 months of life. RESULTS: Five dietary patterns were identified: 'Traditional', 'Unhealthy', 'Milk and chocolate', 'Snack' and 'Healthy'. Children who did not receive EBF until they were at least 4 months old had a higher adherence to the 'Unhealthy' and 'Snack' patterns, and older children also consumed more 'Unhealthy' foods. The highest income was associated with the highest consumption of foods of the patterns 'Unhealthy', 'Milk and chocolate' and 'Healthy'. CONCLUSIONS: In view of the results, we emphasize the importance of providing support and encouragement towards EBF in the first months of life, as it can positively influence lifelong eating habits.

OBJECTIVE: To evaluate the ability of anthropometric measurements to identify excess android fat and to propose cut-off points for excess central adiposity in children, according to age and sex. DESIGN: A cross-sectional study with children from a municipality of Minas Gerais, Brazil. Receiver-operating characteristic curve analyses were performed to evaluate waist circumference (WC), waist-to-height ratio (WHtR) and conicity index (C-index) in estimating excess android fat by dual energy X-ray absorptiometry (DXA). SETTING: Viçosa, Minas Gerais, Brazil. SUBJECTS: Children aged 4-9 years (n 788). RESULTS: Overweight prevalence was 29·1 % and android fat percentage was higher among girls. All central fat measurements were able to discriminate excess android fat in the age groups evaluated, especially WC and WHtR, with cut-off points showing good sensitivity and specificity overall. CONCLUSIONS: Because these methods are easy to obtain and inexpensive, it is possible to use WC, WHtR and C-index in population surveys to evaluate central obesity. The proposed cut-off points showed satisfactory values of sensitivity and specificity and can be used in epidemiological studies.
