The EAT-Lancet diet associated cardiovascular health parameters: evidence from a Brazilian study.

BACKGROUND: The EAT-Lancet diet is a diet aimed at promoting population and planetary health from the perspective of sustainable diets in terms of environmental and health aspects. This study aimed to assess the association between adherence to the EAT-Lancet diet and cardiometabolic risk factors among adults and elderly individuals in a capital city in the northeastern region of Brazil. METHODS: This is an analytical cross-sectional observational study from a population-based sample conducted between 2019 and 2020, involving 398 non-institutionalized adults and elderly people, of both sexes from "Brazilian Usual Consumption Assessment" study (Brazuca-Natal). There was a 38% response rate due to the suspension of data collection due to the covid-19 pandemic, but According to the comparative analysis of socioeconomic and demographic variables between the surveyed and non-surveyed sectors, losses were found to be random (p = 0.135, Little's MCAR test). Socioeconomic and lifestyle data, anthropometric measurements, and dietary consumption were collected. We used the Planetary Health Diet Index (PHDI) and the Cardiovascular Health Diet Index (CHDI) for cardiovascular health to assess adherence to the diet's sustainability. The evaluated cardiometabolic parameters included fasting blood glucose, triglycerides, total cholesterol, HDL-C, LDL-C, and systolic and diastolic blood pressure measurements. We also assessed the presence of type 2 diabetes mellitus, arterial hypertension, and dyslipidemia. For the data analyses, sample weights and the effect of the study design were taken into account. Pearson's chi-square test was used to evaluate the statistical significance of frequencies. Multiple linear regression models assessed the associations between PHDI and CHDI and its components and the cardiometabolic parameters. RESULTS: The mean PHDI was 29.4 (95% CI 28.04:30.81), on a total score ranging from 0 to 150 points and the mean CHDI was 32.63 (95% CI 31.50:33.78), on a total score ranging from 0 to 110 points. PHDI showed a significant positive association with the final CHDI score and components of fruits, vegetables, and legumes, and a negative association with Ultra-processed Food (UPF) (p < 0.05). Notably, among the most consumed UPF, the following stand out: "packaged snacks, shoestring potatoes, and crackers" (16.94%), followed by margarine (14.14%). The PHDI exhibited a significant association with diabetes and dyslipidemia, as well as with systolic blood pressure, total cholesterol, and LDL-C. CONCLUSIONS: The results suggest that adopting the EAT-Lancet diet is associated with the improvement of key cardiovascular health indicators.

One-Piece Versus Two-Piece Abutments for Single Crowns in the Esthetic Zone: A Clinical Trial.

OBJECTIVE: To evaluate whether a two-piece abutment is equivalent to a one-piece in peri-implant esthetics, patients' satisfaction, and oral health-related quality of life (OHRQOL) for implant-supported anterior single crown placement. MATERIAL AND METHODS: Thirty implants were allocated sequentially: 15 in the one-piece abutment group (OP) and 15 in the two-piece abutment group (TP). Peri-implant esthetics were evaluated by the pink esthetic score (PES) at temporary crown insertion (T1), after tissue conditioning (T2), and at 30 days after the final crown insertion (T3). OHRQOL was measured using the OHIP-14 and satisfaction was evaluated using the visual analog scale (VAS) at baseline, T1, and T3. Treatment was considered equivalent if the 95% coefficient interval (CI) for mean difference in PES was between -1.5 and +1.5 points. Statistical analysis was performed using Mann-Whitney, SPANOVA, and Student's t-test, with Sidak's posttest, adopting p < 0.05. RESULTS: No differences were found between the groups for any variable and during follow-up. A significant increase in OHRQOL and satisfaction was observed at T3, when compared to baseline (p < 0.05) for both groups. Significant improvements in peri-implant esthetics were also observed throughout the treatment, particularly after tissue conditioning (p < 0.05). Primary and secondary outcomes were evaluated for equivalence, and both abutment types were considered equivalent following the insertion of the temporary crowns. CONCLUSIONS: Two-piece abutment was equivalent to one-piece abutment for peri-implant esthetics, quality of life, or the satisfaction of patients rehabilitated with metal-free single crowns. Tissue conditioning and final crown insertion appear to play a role in improving these outcomes.

Oral health approach in universal health coverage.

OBJECTIVE: This study aimed to map how oral health is addressed within the universal health coverage (UHC). METHODS: This scoping review followed the Joanna Briggs Institute methodology. Searches included the WHO Library and PubMed, Scopus, Embase, LILACS, and Cochrane databases. Quantitative and qualitative studies were included without publication date and language restrictions. RESULTS: A total of 486 studies were retrieved, of which 292 were excluded in the title and abstract screening phase; 121 full-texts were assessed. After the removal of duplicates and unavailable documents, 50 studies were included in the review and categorized according to the level of scientific evidence. CONCLUSION: Few studies discussed oral health within the UHC, mostly because this coverage does not include oral health adequately. When offered, oral health packages are limited and include specific populations. Access and use of oral health services remain guided by economic factors, exposing the theoretical financial protectionism that perpetuates health inequalities.

Development and Validation of the Epidemiological Diagnostic Instrument for Temporomandibular Disorders.

BACKGROUND: Temporomandibular disorders (TMD) are a highly misreported health problem. Its diagnosis is complex and requires the use of valid and reliable instruments. OBJECTIVE: To develop and validate the Epidemiological Diagnostic Instrument for TMD (EDI/TMD). METHODS: Content validity (CV), response process (RP), construct validity (EFA), reliability (inter and intraobserver consistency), and convergence validity of the EDI/TMD were assessed and compared to the Diagnostic Criteria for TMD (DC/TMD). RESULTS: An instrument composed of a 9-question questionnaire and a 12-step clinical protocol was developed. CV analysis reduced the instrument to a 5-question and 7-step clinical protocol (CVI = 0.93). Some instructions were included after the RP. The EFA found three factors: myogenous TMD, arthrogenous TMD, and differential diagnosis. The reliability scores ranged from substantial to excellent. When compared to the DC/TMD, the EDI/TMD total score indicated that this instrument is valid and provides satisfactory diagnostic criteria (Kappa = 0.906; p < 0.001), and can distinguish non-TMD and TMD individuals, with a cut-off point of 4.9 (Sensitivity = 1.0; Specificity = 1.0; AUC = 1.0). For individuals who had both myogenous and arthrogenous TMD, the cut-off point was 14 or higher (Sensitivity = 0.8; Specificity = 1.0; AUC = 0.987). For individuals who had either myogenous TMD (Sensitivity = 1.0; Specificity = 0.88; PPV = 0.89; NPV = 1.0) or arthrogenous TMD (Sensitivity = 0.95; Specificity = 0.87; PPV = 0.83; NPV = 0.96), the cut-off point was between 5 and 13.9, with the highest EFA score being the determinant factor for final diagnosis. CONCLUSION: Based on its psychometric properties, the EDI/TMD is a valid and reliable assessment tool that is capable of diagnosing TMD and classifying its subtypes.

Validation of self-reported measures of nutritional status: a study based on the PNS 2019.

The aim of this study was to analyze the validity of self-reported anthropometric measurements (weight and height) for classifying the nutritional status of Brazilian adults and elderly people using data from the 2019 National Health Survey (PNS). The PNS sample is made up of permanent private households from all of Brazil's federative units and this is a cross-sectional study in which 6,571 records were identified with measured and reported data, with no missing data for one variable being identified when in the presence of another. Validation was carried out with 6,381 data after removing atypical data. The variables used for stratification were: gender, age, race/color, schooling, and income, and the weighted Kappa Coefficient and the Intraclass Correlation Coefficient (ICC) were used to analyze agreement between the nutritional status categories. Accuracy was analyzed based on sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). For construct validity, a Poisson regression was performed for each outcome (measured and self-reported), with the independent variables "gender", "color/race", "schooling", and "family income". All the analyses showed positive results for validation. There was greater reproducibility among adults (18 to 59 years old) compared to the elderly and among men compared to women. This validation indicates a concrete possibility of carrying out an association of observational studies using reported nutritional status as the outcome variable, as an efficient strategy which could minimize the operational difficulties often encountered.

Biomechanical factors associated with patellofemoral pain in children and adolescents.

To investigate the biomechanical factors associated with patellofemoral pain in children and adolescents. A cross-sectional, population-based study conducted in Brazil from 2019 to 2023, involving students from public schools. Adjusted prevalence ratios and their respective 95% confidence intervals for the outcome in relation to independent variables were calculated for association analysis, adopting a significance level of 5%. Out of the total of 283 students, 152 were female and 182 were aged between 16 and 18 years old. A positive association was observed between the presence of patellofemoral pain and a poor movement quality in both lower limbs (right side: p = 0.04 and left side: p = 0.04) as well as with dynamic valgus of the left lower limb (p < 0.01). Patellofemoral pain in children and adolescents is associated with poor movement quality in the lower limbs and dynamic valgus of the left lower limb. Actions targeting these biomechanical factors may be crucial for early diagnosis and clinical treatment of this disfunction.

Congenital syphilis, syphilis in pregnancy and prenatal care in Brazil: An ecological study.

The aim of this research was to evaluate the incidence of congenital syphilis and the ratio between congenital syphilis and syphilis in pregnant women in Brazil according to socioeconomic indicators (inadequate water supply and sanitation; illiteracy at 15 years of age or older; household income per capita; proportion of poor people; Gini index; human development index; and average health expenditure per inhabitant by the health system) and prenatal quality-of-care indicators. We conducted an ecological study using a sample composed of 257 municipalities, each with ≥ 100,000 inhabitants. Data was collected from four public databases: the Brazilian Institute of Geography and Statistics, comprising socioeconomical data from the 2010 census; and the data of 2019 available in the databases of the Department of Informatics of the Brazilian Health System, Information and Management of Primary Care, and the Electronic Citizen Information System. Descriptive analysis of dependent and independent variables and bivariate analysis by Negative Binomial regression were carried out. The mean incidence of congenital syphilis was 38% higher in municipalities with a Human Development Index up to 0.785 (ratio of means [RM] = 1.38; p = 0.049) and 57% higher among populations where less than 50% of primary healthcare services provided a rapid test for syphilis (RM = 1.57; p < 0.001). The ratio between congenital syphilis and syphilis in pregnant women was 29% higher in municipalities with a low household income per capita (RM = 1.29; p < 0.001) and 28% higher in locations where less than 50% of the primary healthcare services provided a rapid test for syphilis (RM = 1.28; p < 0.001). There was no statistical significance of the quality of prenatal care compared to the outcomes. This result underscores the challenges in detecting syphilis infections among pregnant women during prenatal care, consequently increasing the risk of vertical transmission of the disease to the fetus. Traits of inequality in the occurrence of congenital syphilis also draw attention to strategies to reduce health inequities and improve prenatal care.

Patellofemoral pain syndrome in children and adolescents: A cross-sectional study.

OBJECTIVES: To assess the prevalence and associated factors of Patellofemoral Pain Syndrome (PFPS) in children and adolescents. METHOD: A population-based cross-sectional study was conducted with children and adolescents aged 10 to 18 years, who presented a history of peripatellar and/or retropatellar pain, attending elementary or high school in urban public schools in Natal, Brazil. The sample size was calculated based on a minimum outcome prevalence of 22%. RESULTS: A prevalence of 24.7% of PFPS was found. There was a positive association of PFPS with active students (p < 0.01; PR: 2.5; CI: 1.4-4.5), low functional capacity (p < 0.01; PR: 8.0; CI: 5.0-12.8), and those classified as pubertal (p < 0.03; PR: 1.8; CI: 1.0-3.2). CONCLUSION: There was a considerable prevalence of PFPS in children and adolescents, as well as an association between the level of sexual maturation and adjustable determinants, such as the level of physical activity and low functional capacity in this group.

Time living with food insecurity and socio-demographic factors: longitudinal analysis in a city in the semi-arid region of Northeast Brazil.

OBJECTIVE: Food insecurity (FI) is the lack of daily access for everyone to quality food in sufficient quantity. In many populations, it presents as a chronic and persistent condition. This study analysed the association between the length of time living with FI and socio-demographic conditions in households in a semi-arid municipality in the Brazilian Northeast between 2011 and 2019. DESIGN: This is a population-based cohort study among families in the municipality in Northeast Brazil (2011, 2014 and 2019). FI was estimated through the Escala Brasileira de Insegurança Alimentar (EBIA, Brazilian Household Food Insecurity Measurement Scale), and the longitudinal category of time of living with FI was adopted to classify them according to the time they remained in FI during the cohort. The association with the socio-demographic profiles of the population was verified through multinomial logistic regression. SETTING: Households in semi-arid, Northeast of Brazil. PARTICIPANTS: Household respondents interviewed in 2011, 2014 and 2019 (n 274). RESULTS: Sixty-seven percentage (67 %) of families lived in FI in this period. Rural residence, low monthly per capita income and low schooling of the household reference person increased the chances of these families living longer in FI. These overlapping conditions increased the odds of FI in the household. CONCLUSIONS: Coping with FI requires intersectoral intervention that improves the socio-demographic conditions of the population.

Evaluation of properties of concrete coating composites based on polyurethane and reinforcing fibers.

The objective of this study is to evaluate the effect of Fiber-Reinforced Polymer (FRP) coatings on the mechanical properties of concrete structures, especially those used in the production of power distribution poles. These coatings consist of carbon, glass, hybrid, and aramid fibers embedded within a polyurethane matrix. Aramid fabrics from discarded ballistic garments were used to produce FRP. To achieve this, flexural, Charpy impact, and adhesion tests were conducted on the FRP-reinforced concrete. Additionally, Scanning Electron Microscopy (SEM) analyses were performed on the fracture regions of materials tested for impact resistance. The results indicated that all fabrics utilized in the study enhanced the mechanical properties of the concrete specimens in terms of flexural strength and toughness. The observed differences between the fiber types can be attributed to the unique chemical structures of each fiber and their respective interactions with the PU matrix at the interface. These findings suggest that such coatings can significantly improve the mechanical performance of concrete structures.

Advancements and Prospects in Perovskite Solar Cells: From Hybrid to All-Inorganic Materials.

Hybrid perovskites, materials composed of metals and organic substances in their structure, have emerged as potential materials for the new generation of photovoltaic cells due to a unique combination of optical, excitonic and electrical properties. Inspired by sensitization techniques on TiO2 substrates (DSSC), CH3NH3PbBr3 and CH3NH3PbI3 perovskites were studied as a light-absorbing layer as well as an electron-hole pair generator. Photovoltaic cells based on per-ovskites have electron and hole transport layers (ETL and HTL, respectively), separated by an ac-tive layer composed of perovskite itself. Major advances subsequently came in the preparation methods of these devices and the development of different architectures, which resulted in an efficiency exceeding 23% in less than 10 years. Problems with stability are the main barrier to the large-scale production of hybrid perovskites. Partially or fully inorganic perovskites appear promising to circumvent the instability problem, among which the black perovskite phase CsPbI3 (α-CsPbI3) can be highlighted. In more advanced studies, a partial or total substitution of Pb by Ge, Sn, Sb, Bi, Cu or Ti is proposed to mitigate potential toxicity problems and maintain device efficiency.

Validation of self-reported measures of nutritional status: a study based on the PNS 2019 / Validação de medidas autorreferidas para estado nutricional: estudo a partir da PNS 2019

ABSTRACT The aim of this study was to analyze the validity of self-reported anthropometric measurements (weight and height) for classifying the nutritional status of Brazilian adults and elderly people using data from the 2019 National Health Survey (PNS).

RESUMO Este estudo tem o objetivo de analisar a validade da autorreferência de medidas antropométricas (peso e altura) para a classificação do estado nutricional de adultos e idosos brasileiros a partir dos dados da Pesquisa Nacional de Saúde (PNS), edição de 2019. A amostra da PNS é constituída por domicílios particulares permanentes de todas as unidades federativas do Brasil e este é um recorte transversal no qual foram identificados 6.571 registros com dados aferidos e referidos, não sendo identificados dados perdidos para uma variável quando na presença de outra. A validação foi realizada com 6.381 dados após a retirada de dados atípicos. As variáveis utilizadas para estratificação foram: sexo, idade, raça/cor, escolaridade e renda e, para analisar a concordância entre as categorias do estado nutricional, foram utilizados o Coeficiente Kappa ponderado e o Coeficiente de Correlação Intraclasse (CCI). A acurácia foi analisada com base nos valores de sensibilidade, especificidade, valor preditivo positivo (VPP) e valor preditivo negativo (VPN). E para a validade de constructo, foi realizada uma regressão de Poisson para cada desfecho (aferido e autorreferido), com as variáveis independentes "sexo", "cor/raça", "escolaridade" e "renda familiar". Todas as análises mostraram resultados positivos para a validação. Houve uma maior reprodutibilidade entre adultos (18 a 59 anos) quando comparados às pessoas idosas e entre homens quando comparados às mulheres. Esta validação indica uma possibilidade concreta de realizar estudos observacionais de associação tendo como variável de desfecho o estado nutricional referido, como uma estratégia eficiente, podendo minimizar as dificuldades operacionais frequentemente encontradas.

Indices for measurement of sustainable diets: A scoping review.

INTRODUCTION: The current food system is associated with negative impacts on health, food insecurity and environmental harm. Sustainable diets have attracted increasing interest and novel proposals with a global scope have emerged. This scoping review aims to give an overview of the analysis of all the available evidence related to the sustainable diet indices that have been developed based on the EAT-Lancet Commission. METHODS: Searches were conducted in the PubMed, Embase, Web of Science, Scopus and Science Direct databases. This review was conducted following the PRISMA-ScR guidelines. The target population were studies addressed the use of an index or metric for assessing sustainable diets based on the EAT-Lancet Commission Summary Report were included. PCC acronym was used in the design of the study to describe eligibility criteria: P (Population)-Indexes; C (Concept)-Sustainable diets; C (Context)-Knowledge on the structure and applicability of measurement indices of sustainable diets based on EAT-Lancet recommendations available in the literature. Study eligibility criteria were restricted to papers published in English, from January 2019 through October 2022, with no population restriction. RESULTS: A total of 1,458 papers were retrieved, 14 of which were included in the review. Seven measures of sustainable diets were identified as follow: EAT-Lancet diet score (ELD-I), New EAT-Lancet diet score (EAT), Planetary Health Diet Index (PHDI), Sustainable Diet Index (SDI), Sustainable-HEalthy-Diet (SHED), novel Nutrient-Based EAT index (NB-EAT) and World Index for Sustainability and Health (WISH). Most studies were conducted in developed countries, where greater adherence to this type of diet was found. Estimated greenhouse gas emissions was the most reported indicator of sustainability, followed by diet quality and the benefits of sustainable diets with regards to health outcomes. DISCUSSION: We identified barriers that hinder progress towards sustainable diets, including the difficulty of comparing different indices and the tendency to neglect social aspects and the lack of common definitions and metrics. Despite being challenge, we highlight the importance of using indices that assess sustainable diets that harmonize various indicators, as recommended by the EAT-Lancet Commission, in order to promote positive changes towards a more sustainable future.

Cervical ultrasound for endotracheal intubation confirmation in dogs by veterinary students: a cadaveric study.

Although endotracheal intubation is usually a simple and fast procedure in dogs, some situations can be challenging and lead to the risk of tube misplacement in the esophagus-a life-threatening complication. Hence, confirming intubation is a cornerstone whenever this procedure is performed. Methods such as direct visualization or capnography present limitations insofar as they may be unreliable or unavailable under some circumstances. Ultrasound has emerged as a promising tool to confirm intubation in medicine. However, so far little research has been done on the subject in veterinary medicine. This study's main goal was to investigate ultrasound performed by veterinary students as a confirmation method for intubation in canine cadavers after a brief training session (25 minutes). A total of 160 exams were performed with a microconvex probe by 20 students in 11 different cadavers on left and right recumbencies. Overall accuracy was 70.6% with a median success rate of 75% and a median time to diagnosis of 25 seconds. The number of correct diagnoses was statistically higher than the wrong ones (p<0.05) without difference between recumbencies. Sensitivity, specificity, and positive and negative predictive values were 72.5%, 68.8%, 69.9%, and 71.4%, respectively. The fastest diagnosis was performed in just 4 seconds, and among the top-performers, one student had 100% accuracy with a mean time to diagnosis of 16.8 seconds, and four students had approximately 88% accuracy. This study showed for the first time that even inexperienced veterinary students can have acceptable accuracy in confirming endotracheal intubation in dogs after a brief training session.

Apesar de a intubação endotraqueal em cães ser frequentemente um procedimento simples e rápido, algumas situações podem ser desafiadoras e levar ao risco de posicionamento da sonda no esôfago - uma grave complicação. Portanto, a confirmação da intubação é uma etapa crucial sempre que o procedimento for realizado. Métodos como visualização direta ou capnografia apresentam limitações e podem ser pouco confiáveis ou indisponíveis sob certas circunstâncias. A ultrassonografia surgiu como uma ferramenta promissora para confirmação da intubação na medicina. Contudo, até o momento pouco foi estudado na veterinária. O objetivo deste estudo foi investigar a ultrassonografia realizada por estudantes de veterinária como método de confirmação para a intubação em cadáveres caninos após um breve treinamento (25 minutos). Foram realizados 160 exames com transdutor microconvexo por 20 estudantes em 11 cadáveres nos decúbitos direito e esquerdo. A acurácia geral foi 70.6% com medianas de taxa de sucesso de 75% e de tempo para diagnóstico de 25 segundos. O número de diagnósticos corretos foi estatisticamente superior aos errados (p<0.05) sem diferença entre decúbitos. Sensibilidade, especificidade, valor preditivo positivo e negativo foram, respectivamente: 72.5%; 68.8%; 69.9% e 71.4%. O diagnóstico mais rápido se deu em 4 segundos e entre os estudantes com melhor performance, um se destacou com 100% de acurácia e tempo médio para diagnóstico de 16.8 segundos enquanto quatro outros obtiveram 88% de acurácia. Este estudo demonstrou pela primeira vez que mesmo estudantes de veterinária inexperientes podem atingir uma acurácia aceitável na confirmação da intubação endotraqueal em cães após um breve treinamento.

Factor analysis and cronbach's alpha for studying the knowledge of adolescents on HIV/AIDS: a construct validation study

To analyze the efficacy and psychometric properties of the Knowledge, Attitudes, and Practices Questionnaire when applied to adolescents. It was a cross-sectional construct validation study. Ten questions on the knowledge of HIV/AIDS were selected from the questionnaire for further data analysis and applied to 623 adolescents attending high school. The Statistical Package for the Social Sciences (SPSS) 25.0™ and Stata 14.0 software processed the data. Cronbach's Alpha verified the reliability of items, and the mean of each value ranged from 0.198 to 0.379. Factor analysis assessed the structure of correlations between variables. The resulting factors were lifestyle/habits, preventive actions, and endogenous and exogenous transmission. The scale was reliable for the studied population, ensuring the quality of the instrument.

Dietary and Nutritional Profiles among Brazilian Adolescents.

(1) Background: The present study analyzed the prevalence of dietary and nutritional profiles among Brazilian adolescents and their associations with social determinants of health. (2) Methods: A population-based survey was administered to 16,409 adolescents assessed by the 2015 National School Health Survey. A multivariate model of dietary and nutritional profiles was estimated from correspondence analysis. (3) Results: The dietary and nutritional profiles more prevalent among Brazilian adolescents were "lower nutritional risk dietary pattern and eutrophic" (42.6%), "lower nutritional risk dietary pattern and overweight" (6.8%), and "higher nutritional risk dietary pattern and overweight" (6.0%). Healthier profiles were associated with less urbanized territories, health-promoting behaviors, and families with worse material circumstances. The less healthy profiles were associated with more urbanized environments, health risk behaviors, and families with better material circumstances. (4) Brazilian adolescents have different dietary and nutritional profiles that are characterized by sociopolitical and economic contexts, family material and school circumstances, and the behavioral and psychosocial health factors of the individuals. All of this points to the social determination of these health problems among adolescents in Brazil.

Chronic diseases and emotional disorders are associated with low perception of quality of life in food insecurity/security.

Understanding individual perception of Quality of Life (QoL) can help combat social and health inequalities. We aimed to identify factors associated with Low Perceived Quality of Life (LPQoL) in 295 adults and older adults with food security and food insecurity, in the city of Natal, Brazil. A cross-sectional study was conducted from June to December 2019, with collection of data on socioeconomic demographic status, lifestyle information, non-communicable diseases (NCDs) and risk factors, emotional disorders, food (in) security and quality of life. To assess food insecurity, the Brazilian Scale of Food Insecurity-EBIA was used, and the WHOQOL-Bref questionnaire was used to assess quality of life. Poisson's Regression was used to verify associations between variables and LPQoL, stratifying the sample into food secure (FS) and food insecure (FI) groups. In the FI group, being overweight, older adult, having no partner, drinking alcoholic beverages twice a week or more, and not having daily availability of water were associated with LPQoL, and in the FS group, having diabetes, monthly family income in the 1st and 2nd tertiles, and never having studied was associated with LPQoL. Reporting emotional disorders and sleeping < 7 h/day were associated with LPQoL in both FI and FS groups. LPQoL was associated with the occurrence of NCDs and risk factors, and emotional disorders, regardless of the food security measure. However, the lack of adequate access to water highlights the social vulnerability of the FI group.

Social determinants of health associated with the experience of hunger among Brazilian adolescents. / Determinantes sociais em saúde associados à vivência da fome entre adolescentes do Brasil.

The aim of this study was to identify social determinants of health associated with the experience of hunger among school-age adolescents in Brazil. We conducted a cross-sectional study with a sample of 16,526 adolescents using data from the 2015 National School-based Student Health Survey. Experience of hunger was determined based on the answer to the question "In the last 30 days, how often have you been hungry because there wasn't enough food at home?" The social determinants of health were analyzed using Poisson regression with robust variance. The prevalence of the experience of hunger was 22.8% (95%CI: 21.9-23.7). The experience of hunger was directly associated with being male (PR = 1.12; 95%CI: 1.07-1.16); not being overweight (PR = 1.08; 95%CI: 1.04-1.13 ); irregular consumption of beans (PR = 1.20; 95%CI: 1.13-1.26), vegetables (PR=1.16; 95%CI: 1.09-1.22) and fruit (PR = 1.19; 95%CI: 1.13-1.24); body dissatisfaction (PR = 1.26; 95%CI: 1.18-1.35); and not regularly eating lunch or dinner with parents or guardians (PR = 1.41; 95%CI: 1.32-1.52). An inverse association was found between the experience of hunger and maternal education level and living in the Mid-West, Southeast and South. The findings show that the experience of hunger among Brazilian adolescents coexists with risky eating behaviors, body dissatisfaction, and social inequality.

Objetivou-se identificar determinantes sociais em saúde associados à vivência da fome entre adolescentes escolares brasileiros. Foi realizado um estudo transversal com microdados de 16.526 adolescentes da Pesquisa Nacional de Saúde do Escolar 2015. A vivência da fome foi estimada considerando a frequência com que o adolescente havia ficado com fome por não ter comida suficiente em casa no mês anterior à pesquisa. Para a análise dos determinantes sociais em saúde foi realizada Regressão de Poisson com variância robusta. Verificou-se, no Brasil, que a vivência da fome foi de 22,8% (IC95%: 21,9-23,7) entre adolescentes. Essa associou-se diretamente ao sexo masculino (RP=1,12; IC95%: 1,07-1,16), a não ter excesso de peso (RP=1,08; IC95%: 1,04-1,13), ao consumo irregular de feijão (RP=1,20; IC95%: 1,13-1,26), de legumes e verduras (RP=1,16; IC95%: 1,09-1,22) e de frutas (RP=1,19; IC95%: 1,13-1,24), à insatisfação corporal (RP=1,26; IC95%: 1,18-1,35) e ao consumo irregular de almoço ou jantar com os responsáveis (RP=1,41; IC95%: 1,32-1,52); e inversamente ao gradiente de escolaridade materna, e às macrorregiões do complexo Centro-Sul. Os resultados indicam a coexistência da fome, comportamentos alimentares de risco nutricional, insatisfação corporal e condições de iniquidade social entre adolescentes brasileiros.

Social Determinants of Obesity and Stunting among Brazilian Adolescents: A Multilevel Analysis.

(1) Background: The purpose of this study was to identify the prevalence of obesity and stunting among Brazilian adolescents and its associations with social determinants of health (individual, family, and school), grounded on the necessity of investigating the determinants of nutritional problems within this population. (2) Methods: A population-based survey was administered to 16,556 adolescents assessed by the 2015 National School Health Survey. Multivariate models of obesity and stunting were estimated from Multilevel Poisson Regressions. (3) Results: The prevalence of obesity among Brazilian adolescents (10.0%; 95% CI: 9.4-10.6) was associated directly with indifference or dissatisfaction with body image, with eating breakfast four or fewer days a week, living with up to four people in the household, studying in private schools, and being from the South region, and was inversely associated with being female, 15 years old or older, with having the highest nutritional risk eating pattern, dining at fast-food restaurants, and eating while watching television or studying. The prevalence of stunting (2.3%; 95% CI: 2.0-2.8) was directly associated with the age of 15 years or older, and inversely associated with the lower number of residents living in the household, maternal education-decreasing gradient from literate to college level education, studying in urban schools, and being from the South and Central-West regions. (4) Conclusions: Obesity in adolescence presented behavioral determinants. Stunting and obesity have structural social determinants related, respectively, to worse and better socioeconomic position among Brazilian adolescents.
