    ABSTRACT: Objective: To evaluate the relationship between the stages of somatic maturation and body composition in eutrophic female adolescents with or without excessive body fat. Methods: Cross-sectional study of 118 female adolescents, from 14 to 19 years-old, in Viçosa, Minas Gerais, Southeast Brazil. The adolescents were divided in two groups: Group 1 (G1), eutrophic with adequate body fat percentage, and Group 2 (G2), eutrophic with high body fat percentage. The somatic maturation was assessed by the formula for estimating the Peak Height Velocity (PHV). Results: The PHV had higher average score in G1 adolescents compared to G2 (0.26 versus 0.05; p=0.032). There was an association between G1, G2 and the somatic maturation (p=0.049). The female adolescents before and during PHV presented higher values of fat body BMI (p=0.034) and percentage of central fat (p=0.039) compared to the adolescents after PHV. There was a correspondence between before PHV stage and the excess of body fat (α=0.751). Conclusions: There was an association between somatic maturation and body composition in eutrophic female adolescents. Length, BMI and fat percentage were different among the somatic maturation stages. It is relevant to evaluate the somatic maturation and the changes occurring in the body composition during adolescence in order to better evaluate and manage the nutritional status and the body fat excess.

    ABSTRACT: Being a signatory to international agreements that recognize the Human Right to Adequate Food (HRAF) and having enshrined this right into its Constitution, the Brazilian state imposes a duty to provide, protect and promote the HRAF. For this it is necessary to incorporate the principles of the HRAF into the process of planning and executing the actions of Food and Nutrition Security (FNS). The objective was to analyze the process of mainstreaming of the HRAF in the new institutional design of the National School Nutrition Program (NSNP). This is in line with the principles laid down in General Comment No 12 of the Guide for Policy Analysis and Public Programs and nutritional Food Security under the Perspective of Human Rights and the Organic Law on Food and Nutrition Security (OLFNS). The results show that the new regulatory framework of the NSNP indicates a paradigm shift that is characterized by a gradual decline in the perception of NSNP as policy of a welfare nature. Concomitantly, there is an increase in the concept of the benefit of school food as a right, with the caveat that the construction of a new regulatory framework, although essential, is not sufficient for full implementation of the HRAF.

    ABSTRACT: this study was performed to determine the predictive capacity of four different bioelectrical impedance analysis (BIA) devices in the assessment of adolescents, with and without a protocol. a cross-sectional study was performed with 215 adolescents aged 10 to 14 years, of both genders, evaluated through anthropometry and body composition by dual energy X-ray absorptiometry (DXA) and by four different BIA devices, with and without a protocol. The following tests were used: Kolmogorov-Smirnov's, chi-squared, Student's t or Mann-Whitney's, Kruskal-Wallis's, Wilcoxon's, and kappa index. The ROC curves were constructed and the sensitivity, specificity, and positive and negative predictive values were calculated. of the 215 adolescents, 44.2% had excessive body fat. The tetrapolar BIA device equipped with eight tactile electrodes showed more sensitivity and results that were closer to those obtained by DXA (area under the ROC curve [AUC] = 0.964 with protocol and AUC = 0.973 without protocol, p < 0.001), as well as greater agreement (k = 0.67 with protocol and k = 0.63 without protocol, p < 0.001). The evaluation without protocol was similar to that by DXA in most investigated situations (p > 0.05). BIA is capable of predicting alterations in adolescents' body composition. When it is impossible to perform the assessment with a protocol, its results may be useful in population studies.

    ABSTRACT: OBJECTIVE To analyze methodological and ethical aspects in the sexual maturation assessment of adolescents. DATA SOURCES Books and theses, articles and legislations on the Medline, SciELO, Science Direct databases, besides institutional documents of the World Health Organization and the Pediatric Societies of Brazil and São Paulo, considering the period from 1962 to 2012. The following keywords were used in Portuguese and English: "sexual maturation", "self-assessment", "ethics", "OBJECTIVE assessment of sexual maturation", "puberty", "adolescent", and "adolescentdevelopment". DATA SYNTHESIS The sexual maturation assessment is used in populatinal studies and in clinical daily care. The direct evaluation is performed by a specialized physician, whereas the self-assessment is carried out by the adolescent. This evaluation should be carefully performed in the appropriate place, taking into account the ethical aspects. The patient should not be constrained and the physician must respect the privacy and the confidentiality. Before this evaluation and independently of the used method, the adolescent should receive information and explanation about the procedure and the tools that will be applied. Furthermore, the patient has the right to want or not an adult close to him. CONCLUSIONS Validation studies showed that self-assessment is inferior to clinical assessment and should, therefore, be performed only when the direct examination by physicians is not possible.

    ABSTRACT: To assess the factors related to the presence of polycystic ovary syndrome (PCOS) in adolescents. This was a cross-sectional study, with female adolescents from 15 to 18 years old, divided into: group 1 (with a medical diagnosis of PCOS) and group 2 (not diagnosed with PCOS). The height-for-age index and the body mass index were used for classifying the nutritional status, and a semi-structured questionnaire was applied. The Mann-Whitney test, Fisher's exact test, Spearman correlation coefficients, and logistic regression were used. This study evaluated 485 adolescents with an average age of 16.3 ± 0.9 years old. The prevalence of PCOS was 6.2%. No difference was found between the groups regarding anthropometric parameters and period of contraceptive use; however, there were differences regarding the age at menarche (p < 0.004). Older age at menarche was a protection factor against the syndrome. An association was found between younger age at menarche and the development of the PCOS in adolescents.

    ABSTRACT: The aim of this study was to analyze body fat anthropometric equations and electrical bioimpedance analysis (BIA) in the prediction of cardiovascular risk factors in eutrophic and overweight adolescents. 210 adolescents were divided into eutrophic group (G1) and overweight group (G2). The percentage of body fat (% BF) was estimated using 10 body fat anthropometric equations and 2 BIA. We measured lipid profiles, uric acid, insulin, fasting glucose, homeostasis model assessment-insulin resistance (HOMA-IR), and blood pressure. We found that 76.7% of the adolescents exhibited inadequacy of at least one biochemical parameter or clinical cardiovascular risk. Higher values of triglycerides (TG) (P = 0.001), insulin, and HOMA-IR (P < 0.001) were observed in the G2 adolescents. In multivariate linear regression analysis, the % BF from equation (5) was associated with TG, diastolic blood pressure, and insulin in G1. Among the G2 adolescents, the % BF estimated by (5) and (9) was associated with LDL, TG, insulin, and the HOMA-IR. Body fat anthropometric equations were associated with cardiovascular risk factors and should be used to assess the nutritional status of adolescents. In this study, equation (5) was associated with a higher number of cardiovascular risk factors independent of the nutritional status of adolescents.

    ABSTRACT: To analyze the process of care provided to premature infants in a neonatal intensive care unit and the factors associated with their mortality. Cross-sectional retrospective study of premature infants in an intensive care unit between 2008 and 2010. The characteristics of the mothers and premature infants were described, and a bivariate analysis was performed on the following characteristics: the study period and the "death" outcome (hospital, neonatal and early) using Pearson's chi-square test, Fisher's exact test or a chi-square test for linear trends. Bivariate and multivariable logistic regression analyses were performed using a stepwise backward logistic regression method between the variables with p<0.20 and the "death" outcome. A p value <0.05 was considered to be significant. In total, 293 preterm infants were studied. Increased access to complementary tests (transfontanellar ultrasound and Doppler echocardiogram) and breastfeeding rates were indicators of improving care. Mortality was concentrated in the neonatal period, especially in the early neonatal period, and was associated with extreme prematurity, small size for gestational age and an Apgar score <7 at 5 minutes after birth. The late-onset sepsis was also associated with a greater chance of neonatal death, and antenatal corticosteroids were protective against neonatal and early deaths. Although these results are comparable to previous findings regarding mortality among premature infants in Brazil, the study emphasizes the need to implement strategies that promote breastfeeding and reduce neonatal mortality and its early component.

    ABSTRACT: This cross-sectional study aimed to: (i) investigate whether obesity and overweight defined according to body mass index (BMI) are good predictors of body fat excess, abdominal adiposity and hypertension in 769 Brazilian children aged 6-11 years, (ii) assess the relationship between overweight/obesity and cardiovascular risk factors. Overweight and obesity were estimated using cut-off points corresponding to World Health Organization 1and 2 SD (standard deviation) scores. Based on the results of a multiple logistic regression analysis, overweight and obesity were significantly associated with body fat excess, abdominal adiposity and hypertension. The prevalence of obesity (10.7%), overweight (18.7%), abdominal adiposity (17.6%) and systolic (10.1%) and diastolic hypertension (9.3%) was high in this population of Brazilian children. The cardiovascular risk factors increased significantly according to the BMI SD scores, indicating that in epidemiologic studies, BMI may be a good indicator of risk for cardiovascular diseases.

    ABSTRACT: Objective: The present study had the objective of comparing the lipid profile, nutritional status and body composition of adolescents and their parents. Methods: A cross-sectional study was conducted with 120 adolescents from 10 to 13 years old, public schools students from the city of Viçosa, Minas Gerais, Brazil and their respective biological parents (104 mothers and 82 fathers). Data was collected regarding weight, height, waist and hip circumference, body fat, triglycerides, total and fraction cholesterol. Besides, taking the skinfold measurements (bicipital, tricipital, subscapular and suprailiac) of the adolescents; and evaluation of sexual maturity, excluding those that were in stage 1 according to Tanner. The statistical treatment includes descriptive analysis, the use of the Student's t-test, Mann Whitney, and Pearson and Spearman correlation. An Odds Ratio was conducted with a confidence interval of 95%, considering p < 0.05 significant. Results: A positive and significant correlation was seen for weight, BMI and total cholesterol between father and son; for all the variables, except body fat and wait/hip ratio between father and daughter; for weight and height between mother and son and BMI between mother and daughter. Adolescents that had both parents with hypertriglyceridemia, with inadequacies of LDL or HDL presented, respectively 19, 20 and 4 times more chances of presenting the same alterations. Conclusion: This study confirmed differences in the anthropometric measurements, body composition and lipid profile between children of overweight, eutrophic and underweight parents, as well as greater chance for the adolescent to present an altered lipid profile when the parents also have presented that alteration.

    ABSTRACT: Objective. To evaluate the effect of exclusive breastfeeding and consumption of other foods in the first six months of life in the nutritional status and body composition of children. Methods. A retrospective cohort study with 185 children aged from 4 to 7 years was monitored during the first months of life in a program of support to breastfeeding. We evaluated weight, height, waist circumference, and body composition by using DEXA. The nutritional status was assessed by the BMI/age index. The parameters of adiposity were classified by using as the cutoff point, the 85th percentile of the sample itself, according to gender and age. Confounding factors considered were variables related to maternal, pregnancy, birth, sociodemographic, health, lifestyle, and diet. Bivariate and multivariate analyses were performed, the latter by means of multiple logistic regression. Results. The median exclusive breastfeeding was 3 months. Of the children, 42.7% received cow's milk and 35.7% received infant formula. Regarding nutritional status, 21.1% of the children showed changes. The variables of infant feeding were not independently associated with nutritional status and body composition of the children and there were no differences between the groups studied. Conclusion. Breastfeeding was not a protective factor to overweight and body fat in children.

    ABSTRACT: This cross-sectional study in 2009 focused on the prevalence of underweight and overweight and associated factors in a sample of 621 elderly individuals in Viçosa, Minas Gerais State, Brazil. Data were obtained through home interviews on nutritional status and socio-demographic and health conditions. Of the total sample, 53.3% were females. Median BMI was 26.40 kg/m² (range = 15.20-46.82) and was lower for men than for women. Prevalence of overweight was high (45%; 95%CI: 40%-49%), decreased with age, was positively associated with female gender and history of arthritis/arthrosis, and was negatively associated with age 80 years or older and smoking. Prevalence of underweight was high in men (18.2%), increased with age, and was positively associated with worse self-rated health. The findings highlight the importance of health strategies that favor lifestyle changes and healthy eating habits.

    ABSTRACT: To compare prevalence of anemia and hemoglobin (Hb) levels in Brazilian pregnant women before and after flour fortification with iron. A repeated cross-sectional panel study of public health care centers of municipalities in the five Brazilian regions was conducted. Retrospective data were obtained from 12,119 medical records of pregnant women distributed in two groups: before fortification (delivery prior to June 2004) and after fortification (date of last period after June 2005). Anemia was defined as Hb<11.0 g/dl. Hb levels according to gestational age were assessed using two references from the literature. Statistical analysis was carried out using chi-squared tests, Student's t tests, and logistic regression, with a significance level of 5%. In the total sample, prevalence of anemia fell from 25% to 20% after fortification (p<0.001). However, important regional differences were evident: while significant reductions were seen in the Northeast (37% to 29%) and North (32% to 25%) regions, where pre-fortification prevalence was high, smaller reductions were seen in the Southeast (18% to 15%) and South (7% to 6%) regions, where prevalence was low. Hb levels according to gestational age were slightly higher in the first months of pregnancy and lower after the third or fourth months, depending on the reference used. Logistic regression analysis showed that group, geographic region, marital status, trimester of pregnancy, initial nutritional status, and prior pregnancy were associated with anemia (p<0.05). Prevalence of anemia decreased after fortification, but remains high in the North and Northeast regions. Although fortification may have played a role in this favorable outcome, the contribution of other public policies implemented during the studied period should also be considered.

    ABSTRACT: Excessive body fat, mainly abdominal fat, is associated with higher cardiovascular risk. However, a fat localisation measurement that would be more indicative of risk in adolescents has not yet been established. This study was conducted in order to evaluate the correlation between body fat location measurements and cardiovascular disease risk factors in female adolescents. A total of 113 girls - 38 eutrophic according to their body mass index but with a high percentage of body fat, 40 eutrophic with adequate body fat, and 35 with excessive weight - were evaluated using 15 anthropometrical measurements and 10 cardiovascular risk factors. The central skinfold was the best measurement for predicting variables such as glycaemia and high-density lipoprotein; waist circumference for insulin and homeostasis model assessment; coronal diameter for total cholesterol and low-density lipoprotein; sagittal abdominal diameter for triglycerides and leptin; hip circumference for blood pressure; and the central/peripheral skinfold ratio for homocysteine. The correlation between the measurements and the number of risk factors showed that waist circumference and the waist/stature ratio produced the best results. The results suggest that the body fat distribution in adolescents is relevant in the development of cardiovascular risk factors. Simple measurements such as waist circumference and the waist/stature ratio were the best predictors of a risk of disease and they should therefore be associated with the body mass index in clinical practice in order to identify those adolescents at higher risk.

    ABSTRACT: The purpose of this observational study, designed as a cross-sectional sample of 621 elderly residents in Viçosa, Minas Gerais state, Brazil was to evaluate the prevalence of inadequate functional ability and associated factors in Brazilian elderly. Interviews were conducted at study subjects' houses using a questionnaire focused on socio demographic information and health conditions. Elderly who reported some difficulty in performing six or more activities, or total inability to carry out at least three activities identified on the scale developed by Katz et al. (1963) and Lawton and Brody (1969) were considered to have inadequate functional ability. Data analysis included frequency distribution, bivariate and multivariate Poisson regression. The prevalence of inadequate functional ability was of 16.2% (95% CI: 13-19%) in the sample analyzed. With aging, there was a significant trend of inadequate functional ability increasing in men (χ(2) for trend=8.481; p=0.003) and women (χ(2) trend=13.667; p<0.001). Factors positively associated with inadequate functional ability were age over 80 years, low monthly income, poor self-health perception, history of hospitalization in the last year, use of 5 or more medicines in the last 15 days; history of depression, history of osteoporosis, and negatively associated to physical activity. Factors associated with inadequate functional ability highlighted in this study demonstrate the importance of health programs in Brazil focused on adults and the elderly in preventing or delaying functional decline and promote healthy aging.

    ABSTRACT: The main nutritional deficiencies during childhood, namely anemia and malnutrition, are predominantly related to socio-economic factors. Thus, as the Bolsa Família Program (BFP) is the main policy to combat poverty, it is expected that it will have an impact on child nutrition. The aim was to analyze the differences in the nutritional situation of children registered with the BFP of a municipality located in Zona da Mata of Minas Gerais state. 446 children aged between 6 and 84 months were evaluated, of which 262 were non-beneficiaries and 184 were beneficiaries. Nutritional evaluation included analysis of weight and height parameters through weight/age, weight/height, height/age and Body Mass Index/age indexes and hemoglobin levels, using the Hemocue. The prevalence of anemia, short stature and obesity were 22.6, 6.3 and 5.2%, respectively, and there were no statistical differences between beneficiaries and non-beneficiaries. The beneficiary group initially had worse socio-economic conditions, but with the BFP it managed to financially match the non-beneficiary group. It is possible that the similarity between the two groups, also in the nutritional status, can be attributed to the program benefits, due to the financial funding as well as to the nutritional monitoring required as a condition of the program.

    ABSTRACT: This study sought to evaluate sociosanitary conditions and their impact on the quality of life of the elderly living in the Teixeiras Municipality in the Southeast Region (MG) of Brazil. Two questionnaires were used: one created specifically to characterize the population in terms of sociosanitary conditions, and WHOQOL-bref, to evaluate quality of life. The correlation between the sociosanitary conditions and quality of life scores were analyzed by logistic regression analysis. Among the variables with a strong correlation with quality of life scores the following stand out: use of medication, need of medical care, lack of private health insurance, comorbidities, sleep problems, and retirement. The results of this study indicate that sociosanitary conditions are high risk factors for low quality of life scores in the elderly. This must be taken into consideration to establish health strategies and policies for this age group.

    ABSTRACT: This study aimed to assess pre-hypertension and hypertension-related factors in 1,125 seven- to-14-year-old subjects enrolled in the public school system in Salvador, Bahia State, Brazil. Exposure variables, namely body mass index, waist circumference, gender, age, physical activity, environmental and housing status, family income, diet, schooling, and maternal age were analyzed by polytomous logistic regression, and the outcome variable was categorized as normal, pre-hypertensive, and hypertensive. Prevalence of high blood pressure was 14.1%, including the prevalence of both hypertension (4.8%) and pre-hypertension (9.3%). An association was shown between pre-hypertension and overweight (OR: 3.13; 95%CI: 1.75-5.57). Hypertension was associated with overweight (OR: 3.02; 95%CI: 1.45-6.28), female gender (OR: 2.49; 95%CI: 1.24-4.98), and high-risk eating patterns (OR: 1.93; 95%CI: 1.04-3.56). In short, prevalence of pre-hypertension and hypertension in children and adolescents was higher among girls and individuals with overweight and inadequate diet.

    ABSTRACT: The association between breastfeeding and obesity is inconsistent by the literature. This study aims to assess whether obesity is associated to occurrence of breastfeeding and to duration of total and exclusive breastfeeding in Brazilian children. A cross-sectional study was conducted with 764 children enrolled in public and private schools from Viçosa, Minas Gerais, Brazil. Obesity (outcome variable) was defined as body mass index above the +2 standard deviations score using sex and age specific standards of World Health Organization. Exposure was the occurrence and duration of breastfeeding. Potential confounders were controlled by multiple logistic regression analysis and were divided in two groups: children (gender, age, birth weight, gestational age, order of birth, number of siblings, number of persons in the residence, type of school, physical activity patterns and time watching television) and mothers (age, nutritional status, level of education, weight gain during pregnancy, smokes currently and during the pregnancy). Prevalence of obesity was 10.7%; 6.8% of the children were not breastfed and 59.0% did not receive exclusive breastfeeding. After adjustment for confounding variables by logistic regression analysis, no statistically significant association was observed between obesity and the occurrence and/or duration of total and exclusive breastfeeding. There was no dose-response effect of duration of breastfeeding on prevalence of obesity. Our results do not support the hypothesis that breastfeeding promotion would reduce obesity in this population. Controversial findings regarding this association by literature indicate a need for further investigations.

    ABSTRACT: The scope of this work was to analyze the main myths and beliefs surrounding breastfeeding for the theoretical-practical perspective of the various studies extant in the literature. The studies were obtained by bibliographical surveys in the main databases (Medline, Lilacs, scielo), retrieved using the key words "Breastfeeding," "Weaning," "Myths" and "Beliefs" (and their versions in English and Spanish). Books, theories, dissertations and publications in international and national organs were also consulted. It was seen that over the centuries there have been doubts surrounding the correct form of suckling newborns based on concepts that include biological aspects and socio-cultural determinants. It was seen that various myths and beliefs surrounding suckling generate either feelings of guilt, anxiety, or feelings of trust and support in the breastfeeding mother with respect to her capacity to produce breast milk. In this respect, it is necessary for healthcare professionals to understand suckling from the maternal standpoint, dispelling myths and beliefs, altering outlooks, in such a way as to comprehend the various factors present in suckling, acting in a more effective way for prolongation and maintenance of breastfeeding.
