title: Validation of an educational tool on healthy eating for schoolchildren

description: ABSTRACT Objective The purpose of this study was to validate the card game The Enigma of the Pyramid about healthy eating, using judges (expert) for the validation of content and design; and the target population (students from the 4th and 5th grades, aged 9-10 years) for the semantic validation (pilot test). Methods The Item-Level Content Validity Index was used to verify the degree of agreement among the experts’ opinions, item by item; and the Scale Level Content Validity Index to determine the arithmetic mean of the proportion of items that receive judgments of “non-disagreement” by the judges. The item that obtained Item-Level Content Validity Index greater or equal to 0.80 and Scale Level Content Validity Index greater or equal to 0.90 was considered validated, which was the coefficient of validity. The binominal test was used to select the items that should be revised/modified, using the p-value of ratio (reject H0 if p≤0.8). Items were validated at significance level of ≤0.05. Results Twenty-two judges and 12 schoolchildren participated in the study. Of the 23 items of the card game, nine were selected for review/modification, of which five were from the language component and four from the suitability component for the target population. Conclusion Once the modifications were made, they were all approved by all participating students, making this educational tool on healthy eating habits available for use with the student population.

title: Genetic control of aluminum tolerance in tropical maize germplasm

description: ABSTRACT Aluminum (Al) toxicity is the most limiting factor to maize crop productivity in acid soils. Therefore, the understanding of inheritance of Al tolerance in maize is important for the developmentof more adequate procedures for Al tolerant genotypes selection. In this sense, the objectives of this study were to determine the inheritance, and the general (GCA) and specific combining ability (SCA) for Al tolerance in tropical maize. First, we evaluated diallel crosses of maize from landrace and hybrid germplasms for Al tolerance through the minimal solution methodology. The DIF data (root growth difference) were analyzed by Griffing diallel model. Later the additive-dominant genetic model proposed by Mather and Jinks (1971) was used to estimate the genetic effects. The results of the diallel analysis showed greater variability associated with the estimates of the SCA for both germplasm. The diallel crosses involving the V 06 (Dente de Ouro 2) landrace stood out by high SCA and GCA for Al tolerance. The generation mean analysis indicated quantitative inheritance of Al tolerance in this germplasm, with most of the variance explained by the additive effects. The heritability in the narrow sense varied from 47% to 71%, indicating the possibility of genetic gain with the selection of tolerant genotypes in F2 generation. Additive gene action associated with intermediate heritability and quantitative inheritance demonstrates the possibility of genetic gains with artificial selection for Al tolerance in this maize germplasm.

title: The transnationalization of normal childbirth in Brazil: a study of the last five decades

description: Abstract In recent years, changes have taken place in Brazilian obstetrics in response to the distance between the national scenario and World Health Organization recommendations and the work of organized civil society. This indicates the need for the national and international contexts to be considered. As such, the aim here is to understand the influence of transnationalism on normal childbirth in Brazil. Documental research was conducted to trace out the development of obstetrics in the country. It was found that the historical trajectory of normal childbirth in Brazil has not necessarily been restricted to national borders, but has been influenced by transnational recommendations and standards, orienting the creation of new regulations.

title: Relative age effect, skeletal maturation and aerobic running performance in youth soccer players

description: Abstract Aims: To investigate the presence of a relative age effect (RAE) and the influence of birth quarters (BQ), semesters (S) as well as skeletal maturation on anthropometric characteristics and aerobic peak speed (PST-CAR) in youth male soccer players. Methods: One hundred players were recruited to participate in this study. Players were allocated into 4 BQ’s and 2 S. Skeletal maturity status was assessed using the Fels method. Assessments for players included determination of body size and composition and PST-CAR. Results: Overall, more players were born in BQ1 (38 %) and S1 (75%). The likelihood of players born in BQ1 and BQ2 being selected was 3.61 to 4.96 times higher than players in BQ3 and BQ4. Players in BQ4 maturing earlier were biologically older than their peers in BQ1. The players in BQ3 and S2 displayed higher PST-CAR compared with players in BQ2 and S1, respectively. However, players of contrasting skeletal maturity status did not differ in aerobic performance. Conclusion: Our findings indicate that coaches and talent scouts are systematically retaining average and early maturing players born in S1 and excluding late maturing players born in BQ4. However, aerobic performance appeared to be dependent on the relative age, but independent of skeletal maturation during puberty.

title: Indicators of Abdominal Adiposity and Carotid Intima-Media Thickness: Results from the Longitudinal Study of Adult Health (ELSA-Brazil)

description: Abstract Background: Abdominal adiposity is a risk factor for cardiovascular disease. Objective: To determine the magnitude of the association between abdominal adiposity, according to five different indicators, and the carotid intima-media thickness (CIMT). Methods: Data from 8,449 participants aged 35 to 74 years from the ELSA-Brazil study were used. The effect of waist circumference (WC), waist-to-hip ratio (WHR), conicity index (C index), lipid accumulation product (LAP) and visceral adiposity index (VAI) on CIMT were evaluated. Data were stratified by gender and analyzed using multivariate linear and logistic regressions. A significance level of 5% was considered. Results: Participants with CIMT &gt; P75 showed a higher frequency of abdominal adiposity (men &gt;72% and women &gt;66%) compared to those with CIMT &lt; P75. Abdominal adiposity was associated with the mean CIMT, mainly through WC in men (0.04; 95%CI: 0.033; 0.058). The abdominal adiposity identified by the WC, WHR, LAP, and VAI indicators in women showed an effect of 0.02 mm on the CIMT (WC: 0.025, 95%CI: 0.016, 0.035; WHR: 0.026, 95%CI: 0.016, 0.035; LAP: 0.024, 95%CI: 0.014; 0.034; VAI: 0.020, 95%CI: 0.010, 0.031). In the multiple logistic regression, the abdominal adiposity diagnosed by WC showed an important effect on the CIMT in both genders (men: OR = 1.47, 95%CI: 1.22-1.77, women: OR = 1.38; 95%CI: 1.17-1.64). Conclusion: Abdominal adiposity, identified through WC, WHR, LAP, and VAI, was associated with CIMT in both genders, mainly for the traditional anthropometric indicator, WC.

title: Distribution of depression, somatization and pain-related impairment in patients with chronic temporomandibular disorders

description: Abstract Objective the aim of this study was to describe the frequency of psychosocial diagnoses in a large sample of patients attending a tertiary clinic for treatment of temporomandibular disorders (TMD). Material and Methods six hundred and ninety-one patients who sought treatment for pain-related TMD were selected. Chronic pain-related disability (Graded Chronic Pain Scale, GCPS), depression [Symptoms Checklist-90 (SCL-90) scale for depression, DEP] and somatization levels (SCL-90 scale for non-specific physical symptoms, SOM) were evaluated through the Research Diagnostic Criteria for TMD (RDC/TMD) Axis II psychosocial assessment; TMD diagnoses were based on the Axis I criteria. Results the majority of patients presented a low disability or no disability at all, with only a small portion of individuals showing a severely limiting, high disability pain-related impairment (4.3%). On the other hand, abnormal scores of depression and somatization were high, with almost half of the individuals having moderate-to-severe levels of depression and three-fourths presenting moderate-to-severe levels of somatization. The prevalence of high pain-related disability (GCPS grades III or IV), severe/moderate depression and somatization was 14.3%, 44% and 74.1% respectively. Gender differences in scores of SCL-DEP (p=0.031) and SCL-SOM (p=0.001) scales were signficant, with females presenting the highest percentage of abnormal values. Conclusion patients with TMD frequently present an emotional profile with low disability, high intensity pain-related impairment, and high to moderate levels of somatization and depression. Therefore, given the importance of psychosocial issues at the prognostic level, it is recommended that clinical trials on TMD treatment include an evaluation of patients’ psychosocial profiles.

title: Hypertension Prevalence, Treatment and Control in Older Adults in a Brazilian Capital City

description: Abstract Background: The diagnosis, treatment and control of arterial hypertension are fundamental for a reduction in cardiovascular outcomes, especially in the elderly. In Brazil, there are few studies that specifically identified these rates in the elderly population. Objective: To verify rates of prevalence, treatment and control of hypertension in elderly people living in the urban area of a Brazilian capital city. Methods: A cross-sectional, population-based, randomized, cluster-based study with 912 non-institutionalized elderly individuals (≥ 60 years), living in urban areas in the city of Goiania, Midwest Brazil. Predictor variables were: age, gender, socioeconomic and lifestyle aspects. Blood pressure measurements were performed at home; patients were considered as having arterial hypertension when SBP and/or DBP ≥ 140/90 mmHg or when using antihypertensive drugs (dependent variable). Rates of hypertension treatment and control were evaluated. Variable association analyses were performed by multivariate logistic regression and level of significance was set at 5%. Results: The prevalence of arterial hypertension was 74.9%, being higher (78.6%) in men (OR 1.4, 95% CI: 1.04-1.92); the treatment rate was 72.6%, with higher rates being observed in smokers (OR 2.06, 95% CI: 1.28-3.33). The rate of hypertension control was 50.8%,being higher in women (OR 1.57, 95% CI: 1.19-2.08). Conclusion: The prevalence rates were high. Treatment and control rates were low and associated with gender, age and lifestyle, indicating the need for early and individual interventions.
