Folic acid supplementation during pregnancy and postpartum depressive symptoms.

OBJECTIVE: To verify whether folic acid supplementation during pregnancy is associated with the occurrence of maternal depressive symptoms at three months postpartum, in the 2015 Pelotas Birth Cohort. METHODS: This study included 4,046 women, who were classified into three groups: did not use folic acid supplementation during pregnancy; used during only one trimester of pregnancy; and used for two or three trimesters. Depressive symptoms were assessed at three months postpartum using the Edinburgh Postnatal Depression Scale (EPDS), at cutoff points ≥ 10 (mild symptoms) and ≥ 13 (moderate to severe intensity). RESULTS: The overall prevalence of mild symptoms was of 20.2% (95%CI 19.0-21.5), and moderate and severe was 11% (95%CI 10.0-12.0). The prevalence of EPDS ≥ 10 was of 26.8% (95%CI 24.0-29.5) among women who did not use folic acid and 18.1% for both those who used it during one trimester of pregnancy (95%CI 16.1-20.1) and those who used it for two or three trimesters (95%CI 16.0-20.2). The prevalence of EPDS ≥ 13 was of 15.7% (95%CI 13.5-17.9) in those who did not use folic acid, 9.1% (95%CI 7.5-10.6) in those who used it for one trimester, and 9.4% (95%CI 7.8-11.0) in those who used it for two or three trimesters. In the adjusted analyses, there was no statistically significant association between the use of folic acid during pregnancy and the occurrence of depressive symptoms at three months postpartum. CONCLUSION: There was no association between folic acid supplementation during pregnancy and postpartum depression at three months.

Iron salt supplementation during gestation and gestational diabetes mellitus.

OBJETIVE: To evaluate the association between the use of iron salts during the first two trimesters of gestation in non-anemic women and the development of gestational diabetes mellitus. METHODS: The study used maternal data from the 2015 Pelotas Birth Cohort. All non-anemic women at the 24th week of gestation (n = 2,463) were eligible for this study. Gestational diabetes mellitus was self-reported by women. Crude and adjusted logistic regression were performed considering level of significance = 0.05. RESULTS: Among the women studied, 69.7% were exposed to prophylactic iron supplementation in the first two trimesters of gestation. The prevalence of gestational diabetes mellitus among those exposed was 8.7% (95%CI: 7.4­10.1) and 9.3% (95%CI: 7.4­11.6) among those who were not exposed. Iron supplementation was not associated with increased risk of gestational diabetes mellitus in crude (OR = 0.9; 95%CI: 0,7­1,3) and adjusted analysis (OR = 1.1; 95%CI :0,8­1,6). CONCLUSIONS: The results suggest that routine iron use in non-anemic pregnant women does not increase the risk of developing gestational diabetes. This evidence supports the existing national and international guidelines, in which prophylactic iron supplementation is recommended for all pregnant women as soon as they initiate antenatal care in order to prevent iron deficiency anemia.

Use of vitamins and/or minerals among adults and the elderly in urban areas of Brazil: prevalence and associated factors. / Uso de vitaminas e/ou minerais entre adultos e idosos em áreas urbanas no Brasil: prevalência e fatores associados.

The purpose of the present study was to estimate the prevalence of vitamin and/or mineral use among urban Brazilian populations aged 20 years and over and to identify associated factors. Data from the National Survey on Access, Use and Promotion of the Rational Use of Medicines in Brazil (PNAUM) were analyzed and a population-based cross-sectional study with probability sampling was performed in urban areas of Brazil's five geographic regions from September 2013 to February 2014. The estimated prevalence of vitamin and/or mineral use was 4.8% (95%CI: 4.3-5.3), higher in women 6.4% (95%CI: 5.7-7.1) and in the elderly population 11.6% (95%CI: 10.5-12.8). Vitamin and/or mineral use was associated with the following factors: women, 60 years of age or older, economic class A/B, chronic disease(s) and self-perceived health held as average and very poor/poor. Multivitamins and multiminerals were the most used ones with 24.5% (95%CI 20.1-29.4), followed by calcium and vitamin D with 23.4% (95%CI 19.7-27.5). Data suggest that elderly women should be the reference public for actions aimed at promoting rational use. Nationwide epidemiological surveys should increase monitoring of these products to support the analysis of trends.

O objetivo do estudo foi estimar a prevalência do uso de vitaminas e/ou minerais na população brasileira urbana com idade maior ou igual a 20 anos e identificar os fatores associados ao uso. Foram analisados os dados da Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM), estudo transversal de base populacional, com amostra probabilística, realizada nas áreas urbanas das cinco regiões geográficas do país entre setembro de 2013 e fevereiro de 2014. A prevalência do uso estimada foi de 4,8% (IC95% 4,3-5,3), maior no sexo feminino, 6,4% (IC95% 5,7-7,1), e na população idosa, 11,6% (IC95% 10,5-12,8). O uso de vitaminas e/ou minerais mostrou-se associado aos fatores: sexo feminino, 60 anos ou mais, classe econômica A/B, apresentar doença(s) crônica(s) e autopercepção de saúde regular e muito ruim/ruim. Os multivitamínicos e multiminerais obtiveram maior frequência de uso, 24,5% (IC95% 20,1-29,4), seguido de cálcio e vitamina D, 23,4% (IC95% 19,7-27,5). Os dados sugerem que mulheres idosas devam ser o público referencial para ações de promoção do uso racional. Recomenda-se que os inquéritos epidemiológicos de abrangência nacional possam ampliar a observação desses produtos para possibilitar a análise de tendências.

Self-medication in children aged 0-12 years in Brazil: a population-based study.

OBJETIVE: Studies have shown that the practice of self-medicating children occurs worldwide and is independent of the country's economic level, medication policies, or access to health services. This study aimed to estimate and characterize the prevalence of self-medication in the Brazilian population of children aged up to 12 years. METHODS: We analyzed the data of 7528 children aged up to 12 years whose primary caregivers responded to the National Survey on Access, Use and Promotion of Rational Use of Medicines in Brazil (PNAUM), a cross-sectional population-based study conducted in 245 Brazilian municipalities. The prevalence of self-medication was defined as the use of at least one medication without a doctor's or dentist's indication 15 days before the interview. RESULTS: The prevalence of self-medication was 22.2% and was more frequent in older children belonging to poorer families and without health insurance. The acute conditions for which there was a higher frequency of self-medication were pain, fever, and cold/allergic rhinitis. Analgesics/antipyretics stood out among the most used medications for self-medication. CONCLUSIONS: The prevalence of self-medication to treat acute conditions was high in Brazilian children sampled in PNAUM, emphasizing the management of common symptoms such as pain, fever, and cold/allergic rhinitis in this age group. These findings reinforce the need for educational actions aimed at parents and caregivers.

National Vaccine Coverage Survey 2020: methods and operational aspects.

OBJECTIVE: The national vaccination coverage survey on full vaccination at 12 and 24 months of age was carried out to investigate drops in coverage as of 2016. METHODS: A sample of 37,836 live births from the 2017 or 2018 cohorts living in capital cities, the Federal District, and 12 inner cities with 100 thousand inhabitants were followed for the first 24 months through vaccine record cards. Census tracts stratified according to socioeconomic levels had the same number of children included in each stratum. Coverage for each vaccine, full vaccination at 12 and 24 months and number of doses administered, valid and timely, were calculated. Family, maternal and child factors associated with coverage were surveyed. The reasons for not vaccinating analyzed were: medical contraindications, access difficulties, problems with the program, and vaccine hesitancy. RESULTS: Preliminary results showed that less than 1% of children were not vaccinated, full coverage was less than 75% at all capitals and the Federal District, vaccines requiring more than one dose progressively lost coverage, and there were inequalities among socioeconomic strata, favorable to the highest level in some cities and to the lowest in others. CONCLUSION: There was an actual reduction in full vaccination in all capitals and the Federal District for children born in 2017 and 2018, showing a deteriorating implementation of the National Immunization Program from 2017 to 2019. The survey did not measure the impacts of the COVID-19 pandemic, which may have further reduced vaccination coverage.

RESUMO Objetivo: Estudos têm mostrado que a prática de automedicar crianças ocorre mundialmente e independe do nível econômico do país, das políticas de medicamentos ou do acesso aos serviços de saúde. O objetivo deste estudo foi estimar e caracterizar a prevalência de uso de medicamentos por automedicação na população brasileira de crianças de zero a 12 anos de idade. Métodos: Foram analisadas informações de 7.528 crianças de zero a 12 anos cujo cuidador principal respondeu à Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM), estudo transversal de base populacional realizado em 245 municípios brasileiros. A prevalência de automedicação foi definida como o uso de pelo menos um medicamento sem indicação de médico ou dentista nos 15 dias anteriores à entrevista. Resultados: A prevalência de automedicação foi de 22,2% e foi mais frequente nas crianças mais velhas e pertencentes a famílias mais pobres e sem plano de saúde. As condições agudas para as quais houve maior frequência de automedicação foram dor, febre, resfriado e rinite alérgica. Analgésicos/antipiréticos destacaram-se entre os medicamentos mais utilizados por automedicação. Conclusões: A prevalência de automedicação no manejo de condições agudas foi elevada nas crianças brasileiras amostradas na PNAUM, com destaque para o manejo de sintomas comuns nessa faixa etária, como dor, febre, resfriado e rinite alérgica. Esses achados reforçam a necessidade de ações educativas voltadas aos pais e cuidadores.

Entre as mulheres que não fizeram uso de ácido fólico, a prevalência de EPDS ≥ 10 foi de 26,8% (IC95% 24,0-29,5) e 18,1% tanto entre as que utilizaram durante um trimestre da gestação (IC95% 16,1-20,1), quanto entre as que utilizaram por dois ou três trimestres (IC95% 16,0-20,2). Já a prevalência de EPDS ≥ 13 foi 15,7% (IC95% 13,5-17,9) entre as que não utilizaram ácido fólico, 9,1% (IC95% 7,5-10,6) entre as que utilizaram durante um trimestre e 9,4% (IC95% 7,8-11,0) entre as que utilizaram por dois ou três trimestres. Nas análises ajustadas, não houve associação estatisticamente significativa entre o uso de ácido fólico na gestação e a ocorrência de sintomas depressivos aos três meses pós-parto. CONCLUSÃO Não se observou associação entre a suplementação de ácido fólico na gestação e depressão pós-parto aos três meses.

Iron salt supplementation during gestation and gestational diabetes mellitus

ABSTRACT OBJETIVE To evaluate the association between the use of iron salts during the first two trimesters of gestation in non-anemic women and the development of gestational diabetes mellitus. METHODS The study used maternal data from the 2015 Pelotas Birth Cohort. All non-anemic women at the 24th week of gestation (n = 2,463) were eligible for this study. Gestational diabetes mellitus was self-reported by women. Crude and adjusted logistic regression were performed considering level of significance = 0.05. RESULTS Among the women studied, 69.7% were exposed to prophylactic iron supplementation in the first two trimesters of gestation. The prevalence of gestational diabetes mellitus among those exposed was 8.7% (95%CI: 7.4-10.1) and 9.3% (95%CI: 7.4-11.6) among those who were not exposed. Iron supplementation was not associated with increased risk of gestational diabetes mellitus in crude (OR = 0.9; 95%CI: 0,7-1,3) and adjusted analysis (OR = 1.1; 95%CI :0,8-1,6). CONCLUSIONS The results suggest that routine iron use in non-anemic pregnant women does not increase the risk of developing gestational diabetes. This evidence supports the existing national and international guidelines, in which prophylactic iron supplementation is recommended for all pregnant women as soon as they initiate antenatal care in order to prevent iron deficiency anemia.

Sources of medicines for hypertension and diabetes in Brazil: results from the National Health Survey.

This study aims to analyze the sources people over 18 years of age use to obtain medication for the treatment of hypertension and diabetes, according to sociodemographic characteristics from 2013 to 2019. Data from the Brazilian National Health Survey were analyzed. Most individuals with diagnosis and prescription to pharmacological treatment reported obtaining medicines exclusively from one type of source. The percentage of people who acquired hypertension medicine exclusively from public pharmacies decreased, from 24.5% in 2013 to 16.2% in 2019; while there was an increase in those obtaining from the Popular Pharmacy program, from 23.5% to 31.4%; as well as for out-of-pocket payment, which rose from 30.9% to 35.5% The percentage of people who acquired diabetes medication exclusively from public pharmacies increased from 7.4% to 18.6% and with out-of-pocket payment increased from 21.6% to 26.8%, while the percentage of those who acquired from the Popular Pharmacy program decreased from 47.2% to 36.4%. The percentage of those who acquired medication from various sources decreased for both hypertension and diabetes. For men, white, and those with higher education, the source of medication acquisition, for both conditions, was mostly by out-of-pocket payment. The high number of medicine acquisition from public sources represents an advance in Brazil's response to the treatment of these conditions, but reducing regional differences still represents a challenge to be overcome by the healthcare system.

Racial Differences in Blood Pressure Control from Users of Antihypertensive Monotherapy: Results from the ELSA-Brasil Study. / Diferenças Raciais no Controle da Pressão Arterial em Usuários de Anti-Hipertensivos em Monoterapia: Resultados do Estudo ELSA-Brasil.

BACKGROUND: It seems that the worst response to some classes of antihypertensive drugs, especially angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, on the part of the Black population, would at least partially explain the worse control of hypertension among these individuals. However, most of the evidence comes from American studies. OBJECTIVES: This study aims to investigate the association between self-reported race/skin color and BP control in participants of the Longitudinal Study of Adult Health (ELSA-Brasil), using different classes of antihypertensive drugs in monotherapy. METHODS: The study involved a cross-sectional analysis, carried out with participants from the baseline of ELSA-Brasil. Blood pressure control was the response variable, participants with BP values ≥140/90 mmHg were considered out of control in relation to blood pressure levels. Race/skin color was self-reported (White, Brown, Black). All participants were asked about the continuous use of medication. Association between BP control and race/skin color was estimated through logistic regression. The level of significance adopted in this study was of 5%. RESULTS: Of the total of 1,795 users of antihypertensive drugs in monotherapy at baseline, 55.5% declared themselves White, 27.9% Brown, and 16.7% Black. Even after adjusting for confounding variables, Blacks using angiotensin converting enzyme inhibitors (ACEI), angiotensin receptor blocker (ARB), thiazide diuretics (thiazide DIU), and beta-blockers (BB) in monotherapy had worse blood pressure control compared to Whites. CONCLUSIONS: Our results suggest that in this sample of Brazilian adults using antihypertensive drugs in monotherapy, the differences in blood pressure control between different racial groups are not explained by the possible lower effectiveness of ACEIs and ARBs in Black individuals.

FUNDAMENTO: Aparentemente, a pior resposta a algumas classes de anti-hipertensivos, especialmente inibidores da enzima conversora da angiotensina e bloqueadores de receptor de angiotensina, pela população negra, explicaria, pelo menos parcialmente, o pior controle da hipertensão entre esses indivíduos. Entretanto, a maioria das evidências vêm de estudos norte-americanos. OBJETIVOS: Este estudo tem o objetivo de investigar a associação entre raça/cor da pele autorrelatadas e controle de PA em participantes do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) utilizando várias classes de anti-hipertensivos em monoterapia. MÉTODOS: O estudo envolveu uma análise transversal, realizada com participantes da linha de base do ELSA-Brasil. O controle de pressão arterial foi a variável de resposta, participantes com valores de PA ≥140/90 mmHg foram considerados descontrolados em relação aos níveis de pressão arterial. A raça/cor da pele foi autorrelatada (branco, pardo, negro). Todos os participantes tiveram que responder perguntas sobre uso contínuo de medicamentos. A associação entre o controle de PA e raça/cor da pele foi estimada por regressão logística. O nível de significância adotado nesse estudo foi de 5%. RESULTADOS: Do total de 1.795 usuários de anti-hipertensivos em monoterapia na linha de base, 55,5% se declararam brancos, 27,9%, pardos e 16,7%, negros. Mesmo depois de padronizar em relação a variáveis de confusão, negros em uso de inibidores da enzima conversora de angiotensina (IECA), bloqueadores de receptor de angiotensina (BRA), diuréticos tiazídicos (DIU tiazídicos) e betabloqueadores (BB) in monoterapia tinham controle de pressão arterial pior em comparação a brancos. CONCLUSÕES: Os resultados deste estudo sugerem que, nesta amostra de brasileiros adultos utilizando anti-hipertensivos em monoterapia, as diferenças de controle de pressão arterial entre os vários grupos raciais não são explicadas pela possível eficácia mais baixa dos IECA e BRA em indivíduos negros.

Benzodiazepines utilization in Brazilian older adults: a population-based study.

OBJECTIVE: To evaluate the utilization of benzodiazepines (BZD) in Brazilian older adults, based on the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey of Access, Use and Promotion of Rational Use of Medicines). METHODS: The PNAUM is a cross-sectional study conducted between 2013 and 2014, representing the Brazilian urban population. In the present study, we included 60 years or older (n = 9,019) individuals. We calculated the prevalence of BZD utilization in the 15 days prior to survey data collection according to independent variables, using a hierarchical Poisson regression model. A semistructured interview performed empirical data collection (household interview). RESULTS: The prevalence of BZD utilization in the older adults was 9.3% (95%CI: 8.3-10.4). After adjustments, BZD utilization was associated with female sex (PR = 1.88; 95%CI: 1.52-2.32), depression (PR = 5.31; 95%CI: 4.41-6, 38), multimorbidity (PR = 1.44; 95%CI: 1.20-1.73), emergency room visit or hospitalization in the last 12 months (PR = 1.42; 95%CI: 1.18-1.70 ), polypharmacy (PR = 1.26; 95%CI: 1.01-1.57) and poor or very poor self-rated health (PR = 4.16; 95%CI: 2.10-8.22). Utilization was lower in the North region (PR = 0.18; 95%CI: 0.13-0.27) and in individuals who reported abusive alcohol consumption in the last month (PR = 0.42; 95%CI: 0.19-0.94). CONCLUSION: Despite contraindications, results showed a high prevalence of BZD utilization in older adults, particularly in those with depression, and wide regional and sex differences.

Prevalence of chronic respiratory diseases and medication use among children and adolescents in Brazil - a population based cross-sectional study / Prevalência de doenças respiratórias crônicas e uso de medicamentos entre crianças e adolescentes no Brasil - um estudo transversal de base populacional

Abstract Objectives: to describe the prevalence of chronic respiratory diseases and their pharmacological management in children and adolescents in Brazil. Methods: data from the Pesquisa Nacional de Acesso, Uso e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM)(National Access Survey, Use and Promotion of Rational Use of Medicines in Brazil),a population-based cross-sectional study, were analyzed. Household surveys were conducted between September 2013 and February 2014. We included the population under 20 years of age with chronic respiratory diseases. Prevalence of disease, indication of pharmacological treatment, and their use were assessed. Results: the prevalence of chronic respiratory diseases in children aged less than 6 years old was 6.1% (CI95%= 5.0-7.4), 4.7% (CI95%= 3.4-6.4) in those 6-12 years, and 3.9% (CI95%= 2.8-5.4) in children 13 years and older. Children under 6 showed a higher prevalence of pharmacological treatment indication (74.6%; CI95%= 66.0-81.7), as well as medication use (72.6%; CI95%= 62.8-80.7). Of those using inhalers, 56.6% reported using it with a spacer. The most frequent pharmacologic classes reported were short-acting β2 agonists (19.0%), followed by antihistamines (17.2%). Conclusion: children and adolescents who report chronic respiratory diseases living in urban areas in Brazil seem to be undertreated for their chronic conditions. Pharmacological treatment, even if indicated, was not used, an important finding for decision-making in this population.

Resumo Objetivos: descrever a prevalência de doenças respiratórias crônicas e seu manejo farmacológico em crianças e adolescentes no Brasil. Métodos: foram analisados os dados da Pesquisa Nacional de Acesso, Uso e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM), um estudo transversal de base populacional. As pesquisas domiciliares foram realizadas entre setembro de 2013 e fevereiro de 2014. Incluímos a população com menos de 20 anos de idade com doenças respiratórias crônicas. Foi avaliada a prevalência de doença, indicação de tratamento farmacológico e seu uso. Resultados: a prevalência de doenças respiratórias crônicas em menores de 6 anos foi de 6,1% (IC95%= 5,0-7,4), 4,7% (IC95%= 3,4-6,4) naqueles 6-12 anos e 3,9% (IC95%= 2,8-5,4) em crianças com 13 anos ou mais. Crianças menores de 6 anos apresentaram uma maior prevalência de indicação de tratamento farmacológico (74,6%; IC95%= 66,0-81,7), assim como uso de medicamentos (72,6%; IC95%= 62,8-80,7). Dos usuários de inaladores, 56,6% relataram o uso com espaçador. As classes farmacológicas mais frequentemente relatadas foram β2 agonistas de curta ação (19,0%), seguidos por anti-histamínicos (17,2%). Conclusão: crianças e adolescentes que relatam doenças respiratórias crônicas residentes em áreas urbanas no Brasil parecem ser subtratados para suas condições crônicas. O tratamento farmacológico, mesmo quando indicado, não foi utilizado em sua totalidade, um achado importante para a tomada de decisão nessa população.

O controle de pressão arterial foi a variável de resposta, participantes com valores de PA ≥140/90 mmHg foram considerados descontrolados em relação aos níveis de pressão arterial. A raça/cor da pele foi autorrelatada (branco, pardo, negro). Todos os participantes tiveram que responder perguntas sobre uso contínuo de medicamentos. A associação entre o controle de PA e raça/cor da pele foi estimada por regressão logística. O nível de significância adotado nesse estudo foi de 5%. Resultados Do total de 1.795 usuários de anti-hipertensivos em monoterapia na linha de base, 55,5% se declararam brancos, 27,9%, pardos e 16,7%, negros. Mesmo depois de padronizar em relação a variáveis de confusão, negros em uso de inibidores da enzima conversora de angiotensina (IECA), bloqueadores de receptor de angiotensina (BRA), diuréticos tiazídicos (DIU tiazídicos) e betabloqueadores (BB) in monoterapia tinham controle de pressão arterial pior em comparação a brancos. Conclusões Os resultados deste estudo sugerem que, nesta amostra de brasileiros adultos utilizando anti-hipertensivos em monoterapia, as diferenças de controle de pressão arterial entre os vários grupos raciais não são explicadas pela possível eficácia mais baixa dos IECA e BRA em indivíduos negros.

Abstract Background It seems that the worst response to some classes of antihypertensive drugs, especially angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, on the part of the Black population, would at least partially explain the worse control of hypertension among these individuals. However, most of the evidence comes from American studies. Objectives This study aims to investigate the association between self-reported race/skin color and BP control in participants of the Longitudinal Study of Adult Health (ELSA-Brasil), using different classes of antihypertensive drugs in monotherapy. Methods The study involved a cross-sectional analysis, carried out with participants from the baseline of ELSA-Brasil. Blood pressure control was the response variable, participants with BP values ≥140/90 mmHg were considered out of control in relation to blood pressure levels. Race/skin color was self-reported (White, Brown, Black). All participants were asked about the continuous use of medication. Association between BP control and race/skin color was estimated through logistic regression. The level of significance adopted in this study was of 5%. Results Of the total of 1,795 users of antihypertensive drugs in monotherapy at baseline, 55.5% declared themselves White, 27.9% Brown, and 16.7% Black. Even after adjusting for confounding variables, Blacks using angiotensin converting enzyme inhibitors (ACEI), angiotensin receptor blocker (ARB), thiazide diuretics (thiazide DIU), and beta-blockers (BB) in monotherapy had worse blood pressure control compared to Whites. Conclusions Our results suggest that in this sample of Brazilian adults using antihypertensive drugs in monotherapy, the differences in blood pressure control between different racial groups are not explained by the possible lower effectiveness of ACEIs and ARBs in Black individuals.

Sources of medicines for hypertension and diabetes in Brazil: results from the National Health Survey / Fontes de medicamentos para hipertensão e diabetes no Brasil: resultados da Pesquisa Nacional de Saúde / Fuentes de medicamentos para la hipertensión y diabetes en Brasil: resultados de la Encuesta Nacional de Salud

This study aims to analyze the sources people over 18 years of age use to obtain medication for the treatment of hypertension and diabetes, according to sociodemographic characteristics from 2013 to 2019. Data from the Brazilian National Health Survey were analyzed. Most individuals with diagnosis and prescription to pharmacological treatment reported obtaining medicines exclusively from one type of source. The percentage of people who acquired hypertension medicine exclusively from public pharmacies decreased, from 24.5% in 2013 to 16.2% in 2019; while there was an increase in those obtaining from the Popular Pharmacy program, from 23.5% to 31.4%; as well as for out-of-pocket payment, which rose from 30.9% to 35.5% The percentage of people who acquired diabetes medication exclusively from public pharmacies increased from 7.4% to 18.6% and with out-of-pocket payment increased from 21.6% to 26.8%, while the percentage of those who acquired from the Popular Pharmacy program decreased from 47.2% to 36.4%. The percentage of those who acquired medication from various sources decreased for both hypertension and diabetes. For men, white, and those with higher education, the source of medication acquisition, for both conditions, was mostly by out-of-pocket payment. The high number of medicine acquisition from public sources represents an advance in Brazil's response to the treatment of these conditions, but reducing regional differences still represents a challenge to be overcome by the healthcare system.

Este estudo buscou analisar as fontes utilizadas por pessoas com mais de 18 anos para obter medicamentos para o tratamento de hipertensão arterial e diabetes de acordo com características sociodemográficas de 2013 a 2019. Foram analisados dados da Pesquisa Nacional de Saúde. A maioria dos indivíduos com diagnóstico e prescrição para tratamento farmacológico relatou a obtenção de medicamentos exclusivamente de um tipo de fonte. O percentual de pessoas que adquiriram medicamentos para hipertensão exclusivamente de farmácias públicas diminuiu de 24,5% em 2013 para 16,2% em 2019. Por outro lado, o percentual daqueles que adquiriram pelo Programa Farmácia Popular aumentou de 23,5% para 31,4% e gastos próprios foram de 30,9% para 35,5%. O percentual de pessoas que adquiriram medicamentos para diabetes exclusivamente de farmácias públicas aumentou de 7,4% para 18,6% e gastos próprios aumentaram de 21,6% para 26,8% enquanto o percentual dos que adquiriram da Farmácia Popular diminuiu de 47,2% para 36,4%. O percentual daqueles que adquiriram medicamentos de diversas fontes diminuiu tanto para hipertensão quanto para diabetes. Homens, pessoas brancas e pessoas com Ensino Superior adquiriram medicamentos para ambas as condições principalmente por gastos próprios. O alto número de aquisições de medicamentos de fontes públicas representa um avanço na resposta do Brasil ao tratamento dessas condições, mas reduzir as diferenças regionais ainda é um desafio a ser superado pelo sistema de saúde.

El porcentaje de quienes compraban medicamentos de diferentes fuentes disminuyó tanto para la hipertensión como para la diabetes. Los hombres, los individuos de raza blanca y las personas con educación superior adquirieron medicamentos para ambas afecciones a sus expensas.. El alto número de compras de medicamentos de fuentes públicas es un avance en la respuesta de Brasil al tratamiento de estas condiciones, pero la reducción de las diferencias regionales sigue siendo un desafío para ser superado por el sistema de salud.

Benzodiazepines utilization in Brazilian older adults: a population-based study / Utilização de benzodiazepínicos em idosos brasileiros: um estudo de base populacional

ABSTRACT OBJECTIVE To evaluate the utilization of benzodiazepines (BZD) in Brazilian older adults, based on the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey of Access, Use and Promotion of Rational Use of Medicines). METHODS The PNAUM is a cross-sectional study conducted between 2013 and 2014, representing the Brazilian urban population. In the present study, we included 60 years or older (n = 9,019) individuals. We calculated the prevalence of BZD utilization in the 15 days prior to survey data collection according to independent variables, using a hierarchical Poisson regression model. A semistructured interview performed empirical data collection (household interview). RESULTS The prevalence of BZD utilization in the older adults was 9.3% (95%CI: 8.3-10.4). After adjustments, BZD utilization was associated with female sex (PR = 1.88; 95%CI: 1.52-2.32), depression (PR = 5.31; 95%CI: 4.41-6, 38), multimorbidity (PR = 1.44; 95%CI: 1.20-1.73), emergency room visit or hospitalization in the last 12 months (PR = 1.42; 95%CI: 1.18-1.70 ), polypharmacy (PR = 1.26; 95%CI: 1.01-1.57) and poor or very poor self-rated health (PR = 4.16; 95%CI: 2.10-8.22). Utilization was lower in the North region (PR = 0.18; 95%CI: 0.13-0.27) and in individuals who reported abusive alcohol consumption in the last month (PR = 0.42; 95%CI: 0.19-0.94). CONCLUSION Despite contraindications, results showed a high prevalence of BZD utilization in older adults, particularly in those with depression, and wide regional and sex differences.

RESUMO OBJETIVO Avaliar a utilização de benzodiazepínicos (BZD) em idosos brasileiros,a partir de dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM). MÉTODOS A PNAUM é um estudo transversal, conduzido entre 2013 e 2014, com representatividade da população urbana brasileira. No presente estudo, foram incluídos indivíduos com 60 anos ou mais (n = 9.019). Foi calculada a prevalência de utilização de BZD nos 15 dias anteriores à coleta dos dados da pesquisa, geral e segundo as variáveis independentes, por meio de análise bruta e ajustada, utilizando modelo hierárquico de regressão de Poisson. A coleta de dados foi realizada por meio de entrevista domiciliar. RESULTADOS A prevalência de utilização de BZD em idosos foi de 9,3% (IC95%: 8,3-10,4). Após análise ajustada, foram associados à maior utilização de BZD: sexo feminino (RP = 1,88; IC95%: 1,52-2,32), depressão (RP = 5,31; IC95%: 4,41-6,38), multimorbidade (RP = 1,44; IC95%: 1,20-1,73), visita à emergência ou internação hospitalar nos últimos 12 meses (RP = 1,42; IC95%: 1,18-1,70), polifarmácia (RP = 1,26; IC95%: 1,01-1,57) e autopercepção de saúde ruim ou muito ruim (RP = 4,16; IC95%: 2,10-8,22). A utilização foi menor na região Norte (RP = 0,18; IC95%: 0,13-0,27) e em indivíduos que relataram consumo abusivo de álcool no último mês (RP = 0,42; IC95%: 0,19-0,94). CONCLUSÃO Apesar das recomendações contrárias ao uso, os resultados demonstraram elevada prevalência de utilização de BZD em idosos, particularmente naqueles que apresentam depressão, além de amplas diferenças em relação às regiões do país e ao sexo do indivíduo.

Social Distancing, Mask Use, and Transmission of Severe Acute Respiratory Syndrome Coronavirus 2, Brazil, April-June 2020.

We assessed the associations of social distancing and mask use with symptomatic, laboratory-confirmed severe acute respiratory syndrome coronavirus 2 infection in Porto Alegre, Brazil. We conducted a population-based case-control study during April-June 2020. Municipal authorities furnished case-patients, and controls were taken from representative household surveys. In adjusted logistic regression analyses of 271 case-patients and 1,396 controls, those reporting moderate to greatest adherence to social distancing had 59% (odds ratio [OR] 0.41, 95% CI 0.24-0.70) to 75% (OR 0.25, 95% CI 0.15-0.42) lower odds of infection. Lesser out-of-household exposure (vs. going out every day all day) reduced odds from 52% (OR 0.48, 95% CI 0.29-0.77) to 75% (OR 0.25, 95% CI 0.18-0.36). Mask use reduced odds of infection by 87% (OR 0.13, 95% CI 0.04-0.36). In conclusion, social distancing and mask use while outside the house provided major protection against symptomatic infection.

Does socioeconomic inequality occur in the multimorbidity among Brazilian adults?

OBJECTIVE: To assess the prevalence of multimorbidity among Brazilian adults and its association with socioeconomic indicators. METHODS: Cross-sectional study that used data from the Pesquisa Nacional Sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM - Brazilian National Survey on Access, Use and Promotion of Rational Use of Medicines), carried out between 2013 and 2014. The definition of multimorbidity was the coexistence, in a single individual, of two or more chronic diseases, measured through a list of 14 morbidities (self-reported medical diagnosis throughout life). Economic status and educational level were the socioeconomic indicators used, being the inequalities assessed through the Slope Index of Inequality (SII) and the Concentration Index, stratified by gender. RESULTS: The study comprehended 23,329 adults (52.8% of which were women), with an average age of 37.9 years. Hypertension and high cholesterol levels were the most prevalent conditions. The prevalence of multimorbidity was of 10.9% (95%CI 10.1-11.7) representing nearly 11 million individuals in Brazil, of which 14.5% (95%CI 13.5-15.4) were women and 6.8% (95%CI 5.9-7.8) were men. The occurrence of multimorbidity was similar according to the socioeconomic indicators. In the inequality analysis, we observed absolute and relative differences in men with a higher purchasing power (SII = 3.7; 95%CI 0.3-7.0) and higher educational level (CIX = 7.1; 95%CI 0.9-14.7), respectively. CONCLUSIONS: The frequency of comorbidities in Brazilian adults is high, especially in absolute terms. We only observed socioeconomic inequalities in multimorbidities among men.

Use of drugs for gastrointestinal disorders: evidence from National Survey on Access, Use and Promotion of Rational Use of Medicines.

Objective To estimate the prevalence of use of drugs to treat gastrointestinal disorders, according to demographic, socioeconomic, and health characteristics of the Brazilian population. Methods This is a population-based survey that interviewed individuals residing in cities of the five regions in Brazil. The study sample was composed of 32,348 individuals aged 20 or more years. The profile of use of drugs for gastrointestinal disorders was evaluated considering the variables sex, age, healthcare plan, region, and number of chronic diseases. We also analyzed the frequency of individuals who declared using other drugs, besides those already employed for treatment of gastrointestinal disorders. Additionally, the estimated frequencies of the drug classes used were determined. Results The prevalence of use of drugs for gastrointestinal disorders in Brazil was 6.9% (95% confidence interval - 6.4-7.6), higher in females, among persons aged over 60 years, in those who had a private healthcare insurance, and presented with two or more chronic diseases. It was noted that 42.9% of the aged who used drugs for gastrointestinal disorders were also on polypharmacy. As to the classes of drugs, 82% corresponded to drugs for the food tract and metabolism, particularly proton pumps inhibitors. Conclusion The use of drugs for treatment of gastrointestinal disorders was significant among women and elderly. In this age group, consumption may be linked to gastric protection due to polypharmacy. This study is an unprecedented opportunity to observe the self-reported consumption profile of these drugs in Brazil and, therefore, could subsidize strategies to promote their rational use.

User evaluation of public pharmacy services in Brazil. / Avaliação dos usuários sobre as farmácias públicas no Brasil.

Objective of this article is to evaluate aspects related to the services provided in SUS pharmacies in Brazil, according to users' perception. Data from the National Survey of Access, Use and Promotion of Rational Use of Medicines carried out between 2013 and 2014 were used. Individuals who obtained drugs from public pharmacies were analyzed. To calculate prevalence estimates, the total number of users of drugs with 95%CI was used as denominator. From the age group of 20 to 24 years up to 60 to 64 years, there were significant differences between men and women in terms of use of public pharmacies. More than 30% of people from all socioeconomic classes who did not obtain drugs from SUS pharmacies never thought about this possibility. Not having to wait much time to obtain the medication and a positive evaluation of the opening hours had a strong association with the positive evaluation of users of SUS pharmacies. Opening hours and waiting time are potential barriers in SUS pharmacies. The evaluation of users of SUS was positive, but it pointed to regional differences, and the identification of the magnitude of such differences can contribute to the planning of more effective and equitable policies.

O objetivo deste artigo é avaliar aspectos relacionados aos serviços prestados nas farmácias do SUS do Brasil, segundo a percepção dos usuários. Utilizou-se dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos, realizada entre 2013 e 2014. Analisou-se indivíduos que obtiveram algum medicamento nas farmácias públicas. Para o cálculo das estimativas de prevalências, foi usado como denominador o total de usuários de medicamentos com IC95%. A partir da faixa etária de 20 a 24 anos até 60 a 64 anos observa-se diferenças significativas entre homens e mulheres, em relação ao uso de farmácias públicas. Mais de 30% das pessoas de todas as classes socioeconômica que não obtiveram medicamentos nas farmácias do SUS, nunca pensaram nessa possibilidade. Não costumam esperar para obtenção dos medicamentos e avaliação positiva do horário de funcionamento tiveram uma associação mais forte em relação a avaliação positiva dos usuários das farmácias do SUS. O horário de funcionamento e o tempo de espera são potenciais barreiras nas farmácias do SUS. A avaliação dos usuários que utilizam o SUS é positiva, mas aponta diferenças regionais e a identificação da magnitude dessas pode contribuir na formulação de políticas mais eficazes e equânimes.
