Cut-off points in the waist:height ratio for the prediction of insulin resistance, second stage of sexual maturation in Brazilian adolescents.

The objective of this study was verify the best waist:height ratio (WHtR) cut-off points for the prediction of insulin resistance (IR) according to stage of sexual maturation in Brazilian adolescents. Data were analysed from 37 759 adolescents between 12 and 17 years of age, of both sexes, participating in the ERICA study on cardiovascular risk factors in adolescents ('Estudo de Riscos Cardiovasculares em Adolescentes - ERICA'). The following variables were included sex, age and sexual maturity according to the Tanner stage, waist circumference, height, WHtR, fasting insulin and fasting blood sugar so as to obtain the homeostasis model assessment-estimated insulin resistance (HOMA-IR). We constructed an Receiver Operating characteristic (ROC) curve for each group in order to determine the best WHtR cut-off points for the sample stratified by sex and stratified by sex and sexual maturation stage. The female sex corresponded to 60% of the sample, with a mean age of 14·7 years (sd ± 0·08 years) and 13·1 % had IR. The prediction of IR through the WHtR indicator was better for boys, where all the areas under the ROC curve were superior to 0·70. When stratifying by sex alone, the best WHtR cut-off points found were equal to 0·45 for girls and 0·44 for boys. When stratifying by Tanner maturation stages, the cut-off points were reduced with advancing sexual maturation in the male group, while the opposite occurred in the female group. Among Brazilian adolescents, WHtR is a good predictor of IR evaluated by HOMA-IR, but different cut-off points should be adopted according to sex and sexual maturation stage.

A new combination rule for Spatial Decision Support Systems for epidemiology.

BACKGROUND: Decision making in the health area usually involves several factors, options and data. In addition, it should take into account technological, social and spatial aspects, among others. Decision making methodologies need to address this set of information , and there is a small group of them with focus on epidemiological purposes, in particular Spatial Decision Support Systems (SDSS). METHODS: Makes uses a Multiple Criteria Decision Making (MCDM) method as a combining rule of results from a set of SDSS, where each one of them analyzes specific aspects of a complex problem. Specifically, each geo-object of the geographic region is processed, according to its own spatial information, by an SDSS using spatial and non-spatial data, inferential statistics and spatial and spatio-temporal analysis, which are then grouped together by a fuzzy rule-based system that will produce a georeferenced map. This means that, each SDSS provides an initial evaluation for each variable of the problem. The results are combined by the weighted linear combination (WLC) as a criterion in a MCDM problem, producing a final decision map about the priority levels for fight against a disease. In fact, the WLC works as a combining rule for those initial evaluations in a weighted manner, more than a MCDM, i.e., it combines those initial evaluations in order to build the final decision map. RESULTS: An example of using this new approach with real epidemiological data of tuberculosis in a Brazilian municipality is provided. As a result, the new approach provides a final map with four priority levels: "non-priority", "non-priority tendency", "priority tendency" and "priority", for the fight against diseases. CONCLUSION: The new approach may help public managers in the planning and direction of health actions, in the reorganization of public services, especially with regard to their levels of priorities.

Methylation profile of the ADRB3 gene and its association with lipid profile and nutritional status in adults.

BACKGROUND: Defects in DNA methylation have been shown to be associated with metabolic diseases such as obesity, dyslipidemia, and hypercholesterolemia. To analyze the methylation profile of the ADRB3 gene and correlate it with lipid profile, lipid intake, and oxidative stress based on malondialdehyde (MDA) and total antioxidant capacity (TAC), homocysteine and folic acid levels, nutritional status, lifestyle, and socioeconomic variables in an adult population. A cross-sectional epidemiological study representative of the East and West regions of the municipality of João Pessoa, Paraíba state, Brazil, enrolled 265 adults of both genders. Demographic, lifestyle, and socioeconomic questionnaires and a 24-h recall questionnaire were applied by trained interviewers' home. Nutritional and biochemical evaluation (DNA methylation, lipid profile, MDA, TAC, homocysteine and folic acid levels) was performed. RESULTS: DNA hypermethylation of the ADRB3 gene, analyzed in leukocytes, was present in 50% of subjects and was associated with a higher risk of being overweight (OR 3.28; p = 0.008) or obese (OR 3.06; p = 0.017), a higher waist-hip ratio in males (OR 1.17; p = 0.000), greater intake of trans fats (OR 1.94; p = 0.032), higher LDL (OR 2.64; p = 0.003) and triglycerides (OR 1.81; p = 0.031), and higher folic acid levels (OR 1.85; p = 0.022). CONCLUSIONS: These results suggest that epigenetic changes in the ADRB3 gene locus may explain the development of obesity and non-communicable diseases associated with trans-fat intake, altered lipid profile, and elevated folic acid. Because of its persistence, DNA methylation may have an impact in adults, in association with the development of non-communicable diseases. This study is the first population-based study of the ADRB3 gene, and the data further support evaluation of ADRB3 DNA methylation as an effective biomarker.

Online participatory intervention to promote and support exclusive breastfeeding: Randomized clinical trial.

The support offered to mothers after hospital discharge can be decisive in maintaining exclusive breastfeeding during the first 6 months post-partum. The objective of this study was to assess the impact on the duration of exclusive breastfeeding of a participatory intervention using an online social network. A randomized clinical trial was performed involving 251 mother-child pairings in a university hospital in the Northeast of Brazil, 123 of which assigned to the intervention group and 128 to the control group. After hospital discharge, the intervention group was followed through a closed group of an online social network, where weekly posters were published on topics related to breastfeeding and an active communication was established with the mothers. The groups were interviewed monthly over the phone until the child reached 6 months of age. The duration of exclusive breastfeeding was calculated through survival analysis, and the effect of the intervention was estimated through the Cox regression model. The exclusive breastfeeding frequencies were higher in the intervention group in all follow-up months, reaching 33.3% in the sixth month versus 8.3% in the control group. The median exclusive breastfeeding duration was 149 days (95% CI [129.6, 168.4]) in the intervention group and 86 days (95% CI [64.9, 107.1]) in the control group (P < 0.0001). The proportional risk of early interruption of exclusive breastfeeding was 0.38 (95% CI [0.28, 0.51], P < 0.0001). This intervention had a positive impact on the duration and frequency of exclusive breastfeeding.

Decrease of the DNA methylation levels of the ADRB3 gene in leukocytes is related with serum folate in eutrophic adults.

BACKGROUND: DNA methylation has been evidenced as a potential epigenetic mechanism related to various candidate genes to development of obesity. Therefore, the objective of this study was to evaluate the DNA methylation levels of the ADRB3 gene by body mass index (BMI) in a representative adult population, besides characterizing this population as to the lipid profile, oxidative stress and food intake. METHODS: This was a cross-sectional population-based study, involving 262 adults aged 20-59 years, of both genders, representative of the East and West regions of the municipality of João Pessoa, Paraíba state, Brazil, in that were evaluated lifestyle variables and performed nutritional, biochemical evaluation and DNA methylation levels of the ADRB3 gene using high resolution melting method. The relationship between the study variables was performed using analyses of variance and multiple regression models. All results were obtained using the software R, 3.3.2. RESULTS: From the stratification of categories BMI, was observed a difference in the average variables values of age, waist-to-height ratio, waist-to-hip ratio, waist circumference, triglycerides and intake of trans fat, which occurred more frequently between the categories "eutrophic" and "obesity". From the multiple regression analysis in the group of eutrophic adults, it was observed a negative relationship between methylation levels of the ADRB3 gene with serum levels of folic acid. However, no significant relation was observed among lipid profile, oxidative stress and food intake in individuals distributed in the three categories of BMI. CONCLUSIONS: A negative relationship was demonstrated between methylation levels of the ADRB3 gene in eutrophic adults individuals with serum levels of folic acid, as well as with the independent gender of BMI, however, was not observed relation with lipid profile, oxidative stress and variables of food intake. Regarding the absence of relationship with methylation levels of the ADRB3 gene in the categories of overweight, mild and moderate obesity, the answer probably lies in the insufficient amount of body fat to initiate inflammatory processes and oxidative stress with a direct impact on methylation levels, what is differently is found most of the times in exacerbated levels in severe obesity.

The Study of Cardiovascular Risk in Adolescents--ERICA: rationale, design and sample characteristics of a national survey examining cardiovascular risk factor profile in Brazilian adolescents.

BACKGROUND: The Study of Cardiovascular Risk in Adolescents (Portuguese acronym, "ERICA") is a multicenter, school-based country-wide cross-sectional study funded by the Brazilian Ministry of Health, which aims at estimating the prevalence of cardiovascular risk factors, including those included in the definition of the metabolic syndrome, in a random sample of adolescents aged 12 to 17 years in Brazilian cities with more than 100,000 inhabitants. Approximately 85,000 students were assessed in public and private schools. Brazil is a continental country with a heterogeneous population of 190 million living in its five main geographic regions (North, Northeast, Midwest, South and Southeast). ERICA is a pioneering study that will assess the prevalence rates of cardiovascular risk factors in Brazilian adolescents using a sample with national and regional representativeness. This paper describes the rationale, design and procedures of ERICA. METHODS/DESIGN: Participants answered a self-administered questionnaire using an electronic device, in order to obtain information on demographic and lifestyle characteristics, including physical activity, smoking, alcohol intake, sleeping hours, common mental disorders and reproductive and oral health. Dietary intake was assessed using a 24-hour dietary recall. Anthropometric measures (weight, height and waist circumference) and blood pressure were also be measured. Blood was collected from a subsample of approximately 44,000 adolescents for measurements of fasting glucose, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides, glycated hemoglobin and fasting insulin. DISCUSSION: The study findings will be instrumental to the development of public policies aiming at the prevention of obesity, atherosclerotic diseases and diabetes in an adolescent population.

Costs of obesity attributable to the consumption of sugar-sweetened beverages in Brazil.

Excess sugar is considered one of the primary factors contributing to overweight status. In Brazil, sugar-sweetened beverages (SSBs) contain a significant amount of this nutrient and are consumed excessively. These beverages are associated with adverse health outcomes and impose costs on the healthcare system. The literature currently lacks studies that aim to attribute specific nutrients or foods as causes of diseases and also evaluate their economic impact, especially in middle- and low-income countries. This study aims to estimate the direct and indirect costs of obesity, stratified by sex and age group, resulting from the excessive consumption of sugar-sweetened beverages in Brazil from 2008 to 2020, and to project these costs for the year 2036. The estimation of obesity costs attributable to excessive consumption of SSBs was based on relative risks and the population prevalence of obesity, considering expenditures on hospitalizations and outpatient procedures in the Unified Health System (SUS). Cost information was obtained from the health information systems available at SUS. The highest burden attributable to the consumption of SSBs was observed among younger individuals and progressively decreased with advancing age. The total direct costs in the period between 2008 and 2020 amounted to approximately US$ 6.33 million, 87% of which was related to expenses for females. Additionally, deaths resulting from the consumption of SSBs cost the economy US$ 40 million due to the premature loss of productivity. The total costs of obesity attributable to the consumption of SSBs are substantial, impacting public spending and generating social and productivity losses that burden the economy. It is crucial to develop and implement cost-effective fiscal and regulatory policies aimed at preventing and combating obesity.

Predicting the prevalence of type 2 diabetes in Brazil: a modeling study.

Aims: We adopted a modeling approach to predict the likely future prevalence of type 2 diabetes, taking into account demographic changes and trends in obesity and smoking in Brazil. We then used the model to estimate the likely future impact of different policy scenarios, such as policies to reduce obesity. Methods: The IMPACT TYPE 2 DIABETES model uses a Markov approach to integrate population, obesity, and smoking trends to estimate future type 2 diabetes prevalence. We developed a model for the Brazilian population from 2006 to 2036. Data on the Brazilian population in relation to sex and age were collected from the Brazilian Institute of Geography and Statistics, and data on the prevalence of type 2 diabetes, obesity, and smoking were collected from the Surveillance of Risk and Protection Factors for Chronic Diseases by Telephone Survey (VIGITEL). Results: The observed prevalence of type 2 diabetes among Brazilians aged over 25 years was 10.8% (5.2-14.3%) in 2006, increasing to 13.7% (6.9-18.4%) in 2020. Between 2006 and 2020, the observed prevalence in men increased from 11.0 to 19.1% and women from 10.6 to 21.3%. The model forecasts a dramatic rise in prevalence by 2036 (27.0% overall, 17.1% in men and 35.9% in women). However, if obesity prevalence declines by 1% per year from 2020 to 2036 (Scenario 1), the prevalence of diabetes decreases from 26.3 to 23.7, which represents approximately a 10.0% drop in 16 years. If obesity declined by 5% per year in 16 years as an optimistic target (Scenario 2), the prevalence of diabetes decreased from 26.3 to 21.2, representing a 19.4% drop in diabetes prevalence. Conclusion: The model predicts an increase in the prevalence of type 2 diabetes in Brazil. Even with ambitious targets to reduce obesity prevalence, type 2 diabetes in Brazil will continue to have a large impact on Brazilian public health.

Evaluation of participant satisfaction with community therapy: a mental health strategy in primary care.

Actions aimed at health promotion and disease prevention must prioritize the entry point to the health system. In this sense, it is proposed that Community Therapy (CT) be inserted as a mental health care tool in Primary Care. The purpose of this study is to assess user satisfaction with CT in Primary Care. It is assessment, cross-sectional study with a representative sample of users of CT services in Primary Care in the municipality of João Pessoa, Paraiba, Brazil. Of the 198 interviewees, 165 (83.3%) of the sample reported that they were always respected, evidenced by aspects of respect and dignity; 109 (55.1%) individuals stated they were listened to, revealing internal consistency of 0.7187, and in turn, exhibiting the true validity of the user satisfaction construct with respect to CT. Thus, users displayed positive satisfaction, reflected by respect, dignity, receptiveness, resolution, listening and comprehension received at CT, where empathy is exhibited and mental suffering is relieved. Moreover, CT is an important mental health tool in primary care.

Effects of the economic recession on suicide mortality in Brazil: interrupted time series analysis.

OBJECTIVES: to analyze trends in suicide rates in Brazil in the period before and after the start of the economic recession. METHODS: interrupted time series research using national suicide data recorded in the period between 2012 and 2017 with socioeconomic subgroups analyses. Quasi-Poisson regression model was employed to analyze trends in seasonally adjusted data. RESULTS: there was an abrupt increase in the risk of suicide after economic recession in the population with less education (12.5%; RR = 1.125; 95%CI: 1.027; 1.232) and in the South Region (17.7%; 1.044; 1.328). After an abrupt reduction, there was a progressive increase in risk for the black and brown population and for those with higher education. In most other population strata, there was a progressive increase in the risk of suicide. CONCLUSIONS: the Brazilian economic recession caused different effects on suicide rates, considering social strata, which requires health strategies and policies that are sensitive to the most vulnerable populations.

Care actions for newborns and factors associated with longitudinality in the follow-up care in the neonatal period: Care actions for the newborn.

As newborns are highly vulnerable, they require essential care for adequate child development. This study aimed to assess the care provided to newborns during the first 28 days of life and identify factors associated with adequate care. This was a longitudinal study conducted with 415 mothers and full-term newborns from 4 public maternity hospitals in Natal, Brazil, in 2019. Assistance, socioeconomic, and demographic data were collected 3 times: 48 hours, 7 days, and 28 days after birth. Pearson's chi-square and Poisson regression tests were used with a confidence interval of 95%. Most mothers were between 20 and 29 years old (46.5%), had a high school or higher education (65.3%), a partner (79%), an income of ≤ 1 minimum wage (64, 6%), and were multiparous (62.9%). A total of 29 actions performed in maternity hospitals and 11 in primary healthcare were evaluated. Among the first, 8 (27.6%) were satisfactory; 11 (37.9%), partially satisfactory; and 10 (34.5%), unsatisfactory. In primary care, 2 actions (18.2%) were considered satisfactory; 3 (27.3%) partially satisfactory; and 6 (54.5%) unsatisfactory. In the multivariate analysis of the composite indicators related to adequacy of care, women undergoing vaginal delivery, those who are multiparous, and maternity hospitals at usual risk were associated with better adequacy of care indicators (P ≤ .05). Maternity hospitals accredited to the Baby-Friendly Hospital Initiative had lower chances of the adequacy of promotion to exclusive breastfeeding. The sample loss rate was 13.7% in the first week and 16.6% at the end of the study period. There was inadequacy in the performance of care actions for newborns regarding access and comprehensiveness of care. These weaknesses highlight the need for reassessing skills and coordinating actions in the child's healthcare network.

Tracking of Dietary Patterns in the Secondary Prevention of Cardiovascular Disease after a Nutritional Intervention Program-A Randomized Clinical Trial.

Individuals with a history of previous cardiovascular events have an increased risk of mortality and morbidity, so adherence to a healthy dietary pattern is essential. We aimed to evaluate and compare dietary patterns between the control and the experimental group from the BALANCE Program. A total of 2360 individuals aged 45 years or older with previous cardiovascular disease were included. The individuals were randomized into two groups: intervention (dietary prescription with nutritional recommendations, nutritional education program based on playful strategies, suggestions of typical and accessible Brazilian foods and intensive monitoring) and control (conventional nutritional counseling). The dietary patterns were identified using factor analysis with the principal component extraction method, and the t-Student tests and ANOVA test were performed to evaluate the associated factors. Four dietary patterns were identified for both groups: "Traditional", "Snack", "Western", "Cardioprotective". There was an increase in the variances of the "Cardioprotective" pattern in both groups. Regarding the "Western" pattern, there was a significant reduction in the variances of the experimental group (10.63% vs. 8.14%). Both groups had improvements in eating habits, especially in the first year of follow-up. The greater increase in adherence to the traditional and cardioprotective pattern in the experimental group justifies the initiative of the BALANCE program.

Methodology and indicators for NBCAL monitoring in stores and health services: a multicenter study (Multi-NBCAL). / Metodologia e indicadores para monitoramento da NBCAL em estabelecimentos comerciais e serviços de saúde: estudo multicêntrico (Multi-NBCAL).

The Brazilian Code of Marketing of Infant and Toddlers Food, Nipples, Pacifiers and Baby Bottles (NBCAL), in force in Brazil since 1988, is still systematically violated, exposing mothers and family members to illegal marketing of products that compete with breastfeeding. This study aimed to describe a multicenter study methodology and propose standardized indicators for NBCAL monitoring. This is a Multicenter Study for NBCAL Compliance Assessment (Multi-NBCAL) conducted in seven Brazilian cities: Rio de Janeiro, São Paulo, Ouro Preto (Minas Gerais State), Florianópolis (Santa Catarina State), Brasília (Federal District), João Pessoa (Paraíba State), and Belém (Pará State). Assessment tools were adapted from NetCode/WHO and IBFAN Brazil (International Baby Food Action Network) to conduct two evaluations: (1) evaluation of NBCAL compliance in stores, and NBCAL knowledge and practices of store managers; (2) evaluation of the interaction between the baby food industry and health professionals and post-partum mothers in maternity hospitals. Five indicators were developed to assess NBCAL compliance in stores; seven indicators to assess the knowledge and practices of store managers; five indicators to assess the provision of incentives to maternity hospitals, health professionals, and mothers by sectors; and five indicators to assess NBCAL knowledge and practices of health professionals. The NBCAL assessment methodology with the proposal of standardized indicators allows comparability of studies about this theme. Using these indicators in periodic national or regional investigation can help monitor the level of NBCAL implementation in Brazil.

A Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância, Bicos, Chupetas e Mamadeiras (NBCAL), vigente no Brasil desde 1988, ainda é sistematicamente infringida, expondo mães e familiares ao marketing ilegal de produtos que competem com o aleitamento materno. O objetivo foi descrever metodologia de estudo multicêntrico e propor indicadores padronizados para monitoramento da NBCAL. Estudo Multicêntrico para Monitoramento da NBCAL (Multi-NBCAL) conduzido em sete cidades brasileiras: Rio de Janeiro; São Paulo; Ouro Preto (Minas Gerais); Florianópolis (Santa Catarina); Brasília (Distrito Federal); João Pessoa (Paraíba) e Belém (Pará). Instrumentos de avaliação foram adaptados do NetCode/WHO e da IBFAN Brasil (Rede Internacional em Defesa do Direito de Amamentar) para condução de dois inquéritos: (1) avaliação do cumprimento da NBCAL em estabelecimentos comerciais e das práticas e conhecimento dos seus gerentes sobre a NBCAL; (2) avaliação em maternidades da interação da indústria de alimentos infantis com profissionais de saúde e mães. Foram elaborados cinco indicadores para avaliação do cumprimento da NBCAL em estabelecimentos comerciais; sete indicadores para avaliar conhecimentos e práticas dos seus responsáveis; cinco indicadores para avaliar a oferta de incentivos a maternidades, profissionais de saúde e mães pelas indústrias e cinco indicadores para avaliar conhecimento e práticas de profissionais de saúde quanto à NBCAL. A metodologia de avaliação da NBCAL, com a proposta de indicadores padronizados, permite a comparabilidade de estudos sobre o tema. A utilização desses indicadores em inquéritos periódicos, nacionais ou regionais, pode contribuir para monitorar o grau de implementação da NBCAL no Brasil.

La Norma Brasileña de Comercialización de Alimentos para Lactantes y Niños en la Primera Infancia, Tetillas, Chupetes y Biberones (NBCAL), vigente en Brasil desde 1988, todavía es sistemáticamente infringida, exponiendo a madres y familiares al marketing ilegal de productos que compiten con la lactancia materna. El objetivo fue describir la metodología de estudio multicéntrico y proponer indicadores estandarizados para el monitoreo de la NBCAL. Estudio Multicéntrico para Monitoreo de la NBCAL (Multi-NBCAL) llevado a cabo en siete (7) ciudades brasileñas: Río de Janeiro; São Paulo; Ouro Preto (Minas Gerais); Florianópolis (Santa Catarina); Brasilia (Distrito Federal); João Pessoa (Paraíba) y Belém (Pará). Se adaptaron instrumentos de evaluación del NetCode/OMS y de la IBFAN Brasil (Red Internacional de Acción por la Alimentación Infantil)para la realización de dos encuestas: (1) evaluación del cumplimiento de la NBCAL en establecimientos comerciales y de las prácticas y conocimiento de sus gerentes sobre la NBCAL; (2) evaluación en maternidades de la interacción de la industria de alimentos infantiles con profesionales de salud y madres. Se elaboraron cinco indicadores para la evaluación del cumplimiento de la NBCAL en establecimientos comerciales; siete indicadores para evaluar conocimientos y prácticas de sus responsables; cinco indicadores para evaluar la oferta de incentivos a maternidades, profesionales de salud y madres por las industrias y cinco indicadores para evaluar el conocimiento y prácticas de profesionales de salud, respecto a la NBCAL. La metodología de evaluación de la NBCAL, con la propuesta de indicadores estandarizados, permite la comparabilidad de estudios sobre el tema. La utilización de estos indicadores en encuestas periódicas, nacionales o regionales, puede contribuir a monitorear el grado de implementación de la NBCAL en Brasil.

[Factors associated with the incidence and mortality from COVID-19 in the autonomous communities of Spain]. / Factores asociados a la incidencia y la mortalidad por COVID-19 en las comunidades autónomas.

OBJECTIVE: Analyze the evolution of the epidemic of COVID-19 after the alarm state and identify factors associated with the differences between the autonomous communities. METHOD: Ecological study that used epidemiological, demographic, environmental and variables on the structure of health services as explanatory variables. The analysis period was from March 15th (the start of the alarm state) until April 22nd, 2020. Incidence and mortality rates were the main response variables. The magnitude of the associations has been estimated using the Spearman correlation coefficient and multiple regression analysis. RESULTS: Incidence and mortality rates at the time of decree of alarm status are associated with current incidence, mortality and hospital demand rates. Higher mean temperatures are significantly associated with a lower current incidence of COVID-19 in the autonomous communities. Likewise, a higher proportion of older people in nursing homes is significantly associated with a higher current mortality in the autonomous communities. CONCLUSION: It is possible to predict the evolution of the epidemic through the analysis of incidence and mortality. Lower temperatures and the proportion of older people in residences are factors associated with a worse prognosis. These parameters must be considered in decisions about the timing and intensity of the implementation of containment measures. In this sense, strengthening epidemiological surveillance is essential to improve predictions.

Differences in quality of life and food insecurity between men and women living with HIV/AIDS in the state of Paraíba, Brazil. / Diferenças na qualidade de vida e insegurança alimentar entre homens e mulheres vivendo com HIV/Aids no estado da Paraíba, Brasil.

A prevalence study was conducted to compare quality of life and food insecurity in men and women living with HIV/AIDS. The sample comprised 481 HIV-infected individuals undergoing antiretroviral therapy at a referral hospital in the State of Paraíba, Brazil. Food insecurity and quality of life were assessed using the Brazilian Household Food Insecurity Scale and WHOQOL-HIV Bref, respectively. The results were presented as absolute and relative frequencies and gender differences were tested using the chi-squared test adopting a significance level of 0.05. The findings showed that 40.1% of the sample were women. A higher percentage of women than men had a low income and low education level (65.8% and 72.5%, respectively). Prevalence of food security was lower in women than in men (29.0% compared to 42.7%), and a higher percentage of women than men reported below average quality of life (54.9% compared to 44.4%). The findings reveal that, besides the usual difficulties faced by HIV-infected patients, this group showed a significant level of gender inequality. The management of HIV patient care should consider these important findings, promoting access to care and support services and gender equality so that women can live fairer and more equal lives.

Estudo de prevalência realizado com pessoas vivendo com HIV/Aids, em terapia antirretroviral, com o objetivo de comparar a qualidade de vida e a insegurança alimentar entre homens e mulheres. Foram incluídos aleatoriamente quatrocentos e oitenta e um indivíduos que buscaram atendimento hospitalar. A insegurança alimentar foi avaliada pela Escala Brasileira de Insegurança Alimentar e a qualidade de vida pelo instrumento WHOQOL-HIV-Bref. Os resultados foram apresentados em frequência absoluta e relativa e as diferenças entre os sexos foram testadas com o teste qui-quadrado, considerando significância de 5%. Do total da amostra, 40,1% eram do sexo feminino e essas apresentaram piores condições de renda (65,8%), baixa escolaridade (72,5%), menor prevalência de segurança alimentar (29,02%) e qualidade de vida abaixo da média (54,9%), comparadas com os homens (44,4%). Os resultados do estudo mostram que além das dificuldades enfrentadas pelos portadores do vírus HIV, este grupo apresenta uma importante desigualdade de gênero e a gestão do cuidado voltado a estas pessoas deve considerar este importante achado, promovendo o acesso a políticas sociais e promovendo a isonomia entre os gêneros, em prol de uma vida feminina mais justa e igualitária.

Coronary heart disease and stroke mortality trends in Brazil 2000-2018.

OBJECTIVE: To analyse the mortality rate trend due to coronary heart disease (CHD) and stroke in the adult population in Brazil. METHODS: From 2000 to 2018, a time trend study with joinpoint regression was conducted among Brazilian men and women aged 35 years and over. Age-adjusted and age, sex specific CHD and stroke trend rate mortality were measured. RESULTS: Crude mortality rates from CHD decreased in both sexes and in all age groups, except for males over 85 years old with an increase of 1.78%. The most accentuated declining occurred for age range 35 to 44 years for both men (52.1%) and women (53.2%) due to stroke and in men (33%) due to CHD, and among women (32%) aged 65 to 74 years due to CHD. Age-adjusted mortality rates for CHD and stroke decreased in both sexes, in the period from 2000 to 2018. The average annual rate for CHD went from 97.09 during 2000-2008 to 78.75 during 2016-2018, whereas the highest percentage of change was observed during 2008 to 2013 (APC -2.5%; 95% CI). The average annual rate for stroke decreased from 104.96 to 69.93, between 2000-2008 and 2016-2018, and the highest percentage of change occurred during the periods from 2008 to 2013 and 2016 to 2018 (APC 4.7%; 95% CI). CONCLUSION: The downward trend CHD and stroke mortality rates is continuing. Policy intervention directed to strengthen care provision and improve population diets and lifestyles might explain the continued progress, but there is no room for complacency.

[Infant mortality in the Brazilian countryside: a proposal to overcome epidemiological and demographic invisibility]. / Mortalidade infantil no contexto da ruralidade brasileira: uma proposta para a superação da invisibilidade epidemiológica e demográfica.

The study aimed to compare two concepts of rurality, one proposed by the Brazilian Institute of Geography and Statistics (IBGE) and the other by the World Bank, to determine which is better fitted to the territory's reality, besides analyzing the infant mortality profile of rural municipalities (counties) in the state of Paraíba, Brazil, according to the best criterion for rurality. This was an observational epidemiological study conducted in the state of Paraíba. The method for analyzing rural/urban typologies was based on data mining, using the Apriori algorithm of association. Infant mortality was analyzed with descriptive statistics. The data were obtained from the Mortality Information System of the Brazilian Ministry of Health, from 2007 to 2016, and municipal indicators were from IBGE. The World Bank definition of rurality showed kappa = 0.337, compared to the IBGE definition, with kappa = 0.616. Among the 223 municipalities that were analyzed, the World Bank classified 130 (65.66%) correctly, and the IBGE 183 (82.06%). The predominant epidemiological profile of infant mortality in rural municipalities in Paraiba state was male gender (57.4%), brown skin color (61.1%), age from 0 to 7 days (52.4%), low birthweight (44%), and gestational age less than 37 weeks (43.2%). Underlying cause of death was classified as avoidable death via interventions by the Brazilian Unified National Health System (65.2%). The urban/rural typology adopted by the IBGE was better than the World Bank at classifying the municipalities in Paraiba state. This classification allowed studying the infant mortality profile in rural municipalities, which was similar to the overall profile, except for maternal schooling.

O estudo teve como objetivo comparar duas propostas de ruralidade, do Instituto Brasileiro de Geografia e Estatística (IBGE) e do Banco Mundial, respondendo qual delas melhor adéqua-se à realidade no território e conhecer o perfil da mortalidade infantil nos municípios rurais da Paraíba, Brasil, segundo o critério de ruralidade melhor avaliado. Trata-se de um estudo epidemiológico observacional, realizado no Estado da Paraíba. O método de análise das tipologias rural/urbano baseou-se na mineração de dados, com base no algoritmo de associação Apriori. Para a análise do óbito infantil, utilizou-se a estatística descritiva. Considerou-se os dados do Sistema de Informações sobre Mortalidade do Ministério da Saúde do Brasil, no período de 2007 a 2016, e indicadores municipais do IBGE. A tipologia de ruralidade do Banco Mundial apresentou kappa = 0,337 e a do IBGE kappa = 0,616. Entre os 223 municípios analisados, a tipologia do Banco Mundial classificou corretamente 130 (65,66%) e a do IBGE 183 (82,06%). O perfil epidemiológico predominante nos municípios rurais paraibanos foi sexo masculino (57,4%), cor parda (61,1%), idade entre 0 e 7 dias (52,4%), com baixo peso ao nascer (44%) e idade gestacional menor que 37 semanas (43,2%). A causa básica da morte foi classificada como morte evitável por intervenções do Sistema Único de Saúde (65,2%). A tipologia urbano/rural apresentada pelo IBGE classificou melhor os municípios paraibanos que a do Banco Mundial. Essa classificação possibilitou o estudo do perfil do óbito infantil nos municípios rurais, por meio do qual verificou-se, exceto pela escolaridade da mãe, similaridade com o perfil geral.

El objetivo del estudio fue comparar dos propuestas de ruralidad, la del Instituto Brasileño de Geografía y Estadística (IBGE) y la del Banco Mundial, respondiendo cuál de ellas se adecua mejor a la realidad en el territorio, así como conocer el perfil de mortalidad infantil en municipios rurales de Paraíba, Brasil, según el criterio mejor evaluado de ruralidad. Se trata de un estudio epidemiológico observacional, realizado en el estado de Paraíba. El método de análisis de las tipologías rural/urbana se basó en la mineración de datos, a partir del algoritmo de asociación Apriori. Para el análisis del óbito infantil, se utilizó la estadística descriptiva. Se consideraron los datos del Sistema de Informaciones de Mortalidad del Ministerio de Salud de Brasil, durante el período de 2007 a 2016, así como indicadores municipales del IBGE. La tipología de ruralidad del Banco Mundial presentó kappa = 0,337 y la del IBGE kappa = 0,616. Entre los 223 municipios analizados, la tipología del Banco Mundial clasificó correctamente 130 (65,66%) y la del IBGE 183 (82,06%). El perfil epidemiológico predominante en los municipios rurales paraibanos fue: sexo masculino (57,4%), color pardo (61,1%), edad entre 0 y 7 días (52,4%), con bajo peso al nacer (44%), edad gestacional menor de 37 semanas (43,2%). La causa básica de la muerte fue clasificada como muerte evitable por intervenciones del Sistema Único de Salud (65,2%). La tipología urbano/rural, presentada por el IBGE, clasificó mejor los municipios paraibanos que la del Banco Mundial. Esta clasificación posibilitó el estudio del perfil del óbito infantil en los municipios rurales, a través del cual se verificó, excepto por la escolaridad de la madre, similitud con el perfil general.

Social determinants of health and COVID-19 infection in Brazil: an analysis of the pandemic.

OBJECTIVE: To analyze the influence of socioeconomic, demographic, epidemiological factors, and the health system structure in the evolution of the COVID-19 pandemic in Brazil. METHODS: Ecological study with variables extracted from databases, having the incidence and mortality by COVID-19 until August 23, 2020, in Brazilian states, as response variables. The magnitude of the associations was estimated using Spearman's correlation coefficient and multiple regression analysis. RESULTS: In the Brazilian states, 59.8% of variation in the incidence of COVID-19 was justified by income inequality, significant home densification, and higher mortality. In the case of mortality, those same variables explained 57.9% of the country's variations in federal units. CONCLUSION: Our results indicate that socioeconomic factors influenced the evolution and impact of COVID-19 in Brazil. Thus, we suggest comprehensive actions to ensure economic conditions and strengthening of health networks for populations with socioeconomic vulnerability.

[Relationship between the supply of syphilis diagnosis and treatment in primary care and incidence of gestational and congenital syphilis]. / Relação entre oferta de diagnóstico e tratamento da sífilis na atenção básica sobre a incidência de sífilis gestacional e congênita.

Brazil has reported an increase in the incidence of both gestational and congenital syphilis, posing a serious public health problem in the country. The study aimed to analyze the relationship between the supply of syphilis diagnosis and treatment in primary care and the incidence rates of gestational and congenital syphilis. An ecological study analyzed these incidence rates and the coverage of diagnostic and therapeutic measures in primary care. The study sample consisted of municipalities (counties) with population over 20,000, with coverage by primary care over 50%, and where the majority of the teams were assessed in the second cycle of the National Program for Improvement of Access and Quality of Basic Care. Analysis of the effectiveness of detection and treatment measures was based on the development of the Index of Variation in Vertical Syphilis Transmission. The administration of penicillin and application of the rapid test in these municipalities showed median rates of 41.9% and 67.14%, respectively, with regional differences. Median incidence of gestational syphilis was 6.24 (IQR: 2.63-10.99) in municipalities with a higher supply of the rapid test and 3.82 (IQR: 0.00-8.21) in those with a lower supply, indicating an increase in detection capacity. Municipalities with a reduction in vertical transmission showed higher median rates of teams with supply of rapid testing and (83.33%; IQR: 50.00-100.00) and administration of penicillin (50.00%; IQR: 11.10-87.50), demonstrating a relationship between these measures and the reduction in congenital syphilis. The findings indicate the need to expand these services and to reinforce the importance of reducing vertical transmission.

O Brasil tem registrado aumento nas incidências de sífilis gestacional e congênita, revelando-se como um importante problema de saúde pública no país. O trabalho teve como objetivo analisar a relação entre as ofertas de diagnóstico e tratamento da sífilis na atenção básica e as incidências de sífilis gestacional e congênita. Foi realizado estudo ecológico analisando as incidências desses agravos e a cobertura de ações diagnósticas e terapêuticas na atenção básica. A amostra do estudo foi composta por municípios com população acima de 20.000 habitantes, com cobertura da atenção básica superior a 50% e nos quais a maioria das equipes foi avaliada no segundo ciclo do Programa de Melhoria do Acesso e da Qualidade na Atenção Básica. Para analisar a efetividade das ações de detecção e tratamento foi desenvolvido o Índice de Variação da Transmissão Vertical de Sífilis. A administração da penicilina e a realização de teste rápido nesses municípios obtiveram medianas iguais a 41,9% e 67,14%, respectivamente, com diferenças regionais. A mediana da incidência de sífilis gestacional foi 6,24 (IIQ: 2,63-10,99) em municípios com maior oferta de teste rápido, e de 3,82 (IIQ: 0,00-8,21) naqueles com oferta inferior, apontando aumento na capacidade de detecção. Municípios com redução da transmissão vertical apresentavam maiores medianas dos percentuais de equipes com oferta dos testes rápidos (83,33%; IIQ: 50,00-100,00) e realização de penicilina (50,00%; IIQ: 11,10-87,50), demonstrando relação entre estas ações e a redução de sífilis congênita. Os achados indicam a necessidade de ampliação dessas ofertas e reforça a importância na redução da transmissão vertical.
