Abstract This longitudinal study aimed to investigate the association between self-perceived oral health, oral-health-related quality-of-life (OHRQoL), toothache, and university students’ academic performance or dropout. A cohort of 2,089 students from 64 different courses at a public university in southern Brazil was interviewed in 2016 regarding their self-perceived oral health (Locker instrument; dichotomized into good/poor), OHRQoL (Oral Impacts on Daily Performances instrument, OIDP) and having had any toothache over the last 6 months (yes/no). After three years (2020), the academic records of 1,870 of these students were assessed, their average grade over all courses evaluated, and their dropout status was determined. Multivariable linear or logistic regression adjusting for gender, skin color, age, family income and maternal education was used to associate oral health variables (self-perceived oral health, OIDP, toothache) and academic performance or dropout. In 2016, 28.6% reported negative self-perceived oral health through the Locker instrument and 31.4% had toothache in the last 6 months. Over the next three years, 36.2% had dropped out. In multivariable regression, toothache in the last 6 months had a decrease of 0.32 (β -0.32, CI95% -0.59; -0.04) points in the final grade and were 35% (OR 1.35 CI95% 1.08; 1.69) more likely to dropout than students without toothache. In conclusion, this study showed that worse oral health conditions may be associated with worse academic performance or dropping out.

Abstract Behavioral characteristics may also take part in the etiology of dental caries. Sedentary behavior, especially watching television, is associated with increased intake of foods high in fat or free sugar, which could influence the occurrence of dental caries. The aim of this study was to assess the mediating effect of eating pattern on the relationship between television exposure time and the presence of dental caries in children. A cross-sectional study was conducted with a representative sample of 580 parent-child dyads with children aged 7 to 8 years in 20 public schools in Pelotas, Brazil. Parents or legal guardians were interviewed and provided information on demographic/socioeconomic data, children’s daily television exposure time, and answered the Biological Rhythms Interview for Assessment in Neuropsychiatry for Kids (BRIAN-K-eating pattern domain). Caries was evaluated through clinical examination. The mediating effect of eating pattern on the relationship between television exposure and presence of dental caries was estimated using the parametric g-formula. Prevalence of dental caries was 63%, and 22% of children watched TV 4 or more hours per day. Television exposure had no direct effect on the dental caries experience [odds ratio (OR): 1.05 (95% confidence interval (95%CI): 0.92–1.19)]. Nevertheless, difficulty maintaining regular eating pattern mediated the natural indirect effect of television exposure time (≥ 4 hours/day) on dental caries experience [OR: 1.07 (95%CI): 1.01–1.14)]. The results of this study confirm the indirect pathway between television viewing and dental caries and the role of disordered eating patterns in this association.

The study investigated the factors associated with the self-perception safety of dental students in clinical activities during the COVID-19 pandemic. This cross-sectional study was based on a semi-structured online (google forms) self-applied questionnaire, sent by e-mail to three private Dental Schools in Brazil. The variables were: 1) sociodemographic information; 2) questions about the measures adopted by dental schools before returning to clinical activities; 3) dental students’ self-perception of security; 4) the General Health Questionnaire. Data were submitted to Fisher’s exact test (p<0.05). Of the 294 eligible students, 97% were evaluated and 100% received previous specific biosafety training predominantly theoretical (72.16%) longer than one hour (51.55%). Most students (81.44%) felt secure performing clinical care during the COVID-19 pandemic. Students undergoing specific biosafety training for longer than one hour felt safer than those perfoming training for up to 1 hour (p=0.004). Students from schools where the aerosol-producing restriction was applied felt safer than those without restrictions (p=0.016). Women reported feeling less secure than men (p=0.046), and students who submitted to COVID-19 Specific Biosafety Training felt safer in clinical activities than those submitted to theoretical training only (p=0.011). Students from private universities presenting psychosomatic changes felt less secure in practicing clinical dental care activities (p=0.006). In conclusion, time-spent training in biosafety, restriction of the use of aerosol-producing procedures, and the gender of students were associated with the self-perception safety of students. Students with practical training felt safer in clinical activities for patients with COVID-19 than those who had only theoretical training.

Abstract Objective: to analyze the consumption of healthy eating markers among adolescent students in Pelotas, Rio Grande do Sul, Brazil, in 2019. Methods: this was a cross-sectional study carried out in schools taking part in the Health at School Program. Consumption of the five markers (beans, milk, fruit, cooked vegetables and raw salads) within five days prior to the study, obtained through a self-administered questionnaire, was defined as regular. Association between demographic, socioeconomic and behavioral variables and the outcomes was analyzed using Poisson regression. Results: among the 797 respondents, 2.8% (95%CI 1.8;4.1) reported regular consumption. Beans were the most regularly consumed food (48.3%); fruit, cooked vegetables and raw salads were consumed regularly by less than 30% of the students. Doing physical activities, having breakfast and having meals with the family were associated with regular consumption of the foods assessed. Conclusion: regular consumption of healthy foods was low in this population, and was associated with behavioral factors.

Aim In Brazil, COVID-19 remains one of the epicenters of the pandemic, thus, presential educational activities are suspended. The study aimed to describe the approach of flipped classroom performed to provide social distancing and to maintain teaching activities during COVID-19-pandemic. Methods Flipped Classroom was chosen to be associated with the role-play technique as a central methodology. To bring students closer to activities performed in the non-pandemic period, some actions and assessments were also role-played by Professor simulating patients in virtual meetings. Results Although the changes in the format of the lessons, our approaches stimulated the students maintained the high frequency of students in the activities (almost 100%) providing continuity activities. Conclusions This report can reinforce that meaningful learning can be taught by using a virtual/remote approach. However, the potential positive results observed cannot be used as an excuse to maintain remote teaching activities with the objective of cost-cutting by the institutions.

Aim To verify the validity of maternal reports on the number of deciduous teeth erupted in their children. Methods This cross-sectional study was performed with children enrolled in a Birth Cohort at the age of 12 months in the first stage and 24 months in the second stage. At both stages, children were clinically examined, and mothers reported the number of teeth of their children. Comparison between groups was performed using the Mann-Whitney non-paired Wilcoxon test. Level of agreement between two methods were estimated by the Observed Agreement, Weighted Kappa and Intraclass Correlation coefficients. Results A total of 125 children were examined in the first stage, with mean number of reported teeth of 6.2. In the second stage, 149 children were examined, with mean number of reported teeth of 15.9. High level of agreement, kappa values and intraclass correlation coefficients were observed for both arches in both periods (p<0.001). Conclusions Maternal report on the number of teeth erupted in children was reliable and valid. Thus, it seems to be a useful instrument for collecting data in population-based epidemiological studies targeting young children.

Resumo O objetivo deste estudo é descrever o perfil de utilização dos serviços de atenção primária à saúde, estimado pela Pesquisa Nacional de Saúde (PNS), da população residente em domicílios cadastrados e não cadastrados na Estratégia de Saúde da Família (ESF), nos anos de 2013 e 2019. Estudo transversal realizado com microdados dos inquéritos nacionais de saúde entre 2013 e 2019. A amostra originou-se de uma amostra mestra, composta por um conjunto de unidades de áreas selecionadas em um cadastro. Variáveis sexo, idade, cor da pele, renda, escolaridade, autopercepção de saúde, domicílio cadastrado na ESF, atendimento médico no último ano, tipo de serviço que você procura quando está doente foram selecionados. As variáveis dependentes foram uso de serviços de saúde e uso de serviços públicos de saúde. As variáveis dependentes e independentes foram descritas com os respectivos intervalos de confiança e foi realizada regressão logística ajustada para cada desfecho analisado. Nos serviços públicos de saúde, menor renda, ter doenças crônicas (hipertensão arterial ou colesterol alto), estar grávida e ter uma autopercepção de saúde ruim estiveram associados à maior utilização de serviços de saúde nos dois períodos. Morar em domicílios cadastrados na ESF foi associado aos serviços de saúde mais utilizados (públicos ou privados). A estratégia de saúde da família é uma estratégia importante para expandir o acesso de forma igualitária.

Abstract The objective of this study is to describe the profile of use of primary health care services, estimated by the PNS, of the population living in households registered and not registered with the Famly Health Strategy - FHS, in the years 2013 and 2019. Cross-sectional study carried out using microdata from national health surveys 2013 and 2019. The sample originated from a master sample, consisting of a set of units from selected areas in a register..The variables sex, age, skin color, income, education, self-perceived health, home registered with the FHS, medical care in the last year, type of service you seek when you are ill were selected. The dependent variables were use of health services and use of public health services. The dependent and independent variables were described with the respective confidence interval and adjusted logistic regression was performed for each outcome analyzed. In public health services, lower income, have chronic diseases (arterial hypertension or high cholesterol), be pregnant, and having a bad self-perception of health were associated with used more health services in both periods. Living in registered households was associated with more used health services (public or private). The family health strategy is an important strategy for expanding access equally.

Resumo Objetivo Analisar a associação entre dor dentária, uso de serviços odontológicos e absenteísmo escolar em adolescentes brasileiros. Métodos Estudo transversal, sobre dados da Pesquisa Nacional de Saúde do Escolar (PeNSE 2015). A variável dependente do estudo foi o absenteísmo escolar por motivo de saúde nos últimos 12 meses. Características socioeconômicas, dor dentária e utilização de serviços odontológicos foram as variáveis independentes avaliadas. Empregou-se regressão logística, para estimar odds ratio (OR) e respectivos intervalos de confiança de 95% (IC95%). Resultados Foram incluídos 102.072 escolares. A prevalência de absenteísmo por motivo de saúde foi de 53,7% (IC95% 53,2;54,3). Pela análise ajustada, houve associação entre dor dentária e absenteísmo (OR=1,35 - IC95% 1,26;1,45), e aumento na ocorrência de absenteísmo conforme o maior número de consultas odontológicas. Conclusão Os resultados sugerem que a dor dentária e a frequência de consultas odontológicas podem estar relacionadas ao absenteísmo escolar.

Abstract Objective To analyze association between dental pain, use of dental services and school absenteeism in Brazilian adolescents. Methods This was a cross-sectional study with data from the National School Health Survey (PeNSE 2015). The study’s dependent variable was school absenteeism due to health reasons in the last 12 months. Socioeconomic characteristics, dental pain and use of dental services were the independent variables evaluated. Logistic regression was used to estimate odds ratios (OR) and respective 95% confidence intervals (95%CI). Results Data on 102,072 schoolchildren were included. Absenteeism prevalence due to health reasons was 53.7% (95%CI 53.2;54.3). In the adjusted analysis, there was association between dental pain and school absenteeism (OR=1.35 - 95%CI 1.26;1.45), and an increase in absenteeism occurrence the greater the number of dental visits. Conclusion The results suggest that dental pain and frequency of dental visits may be related to school absenteeism.

Resumo O objetivo deste artigo é descrever os motivos para participação esportiva da população adulta brasileira de acordo com sexo, idade e escolaridade. Trata-se de um estudo transversal com dados da Pesquisa Nacional por Amostras de Domicílios - 2015. Os motivos para praticar ou não esportes no ano anterior foram obtidos por questionário com respostas pré-determinadas. Todas as análises foram realizadas no software Stata 12.1 e estratificadas por gênero. As prevalências de participação em esportes para homens e mulheres foram 31,7% e 16,9%, respectivamente. Entre os homens, os motivos mais frequentes para participação em esportes foram: diversão, qualidade de vida e desempenho. Entre as mulheres, os motivos mais frequentes foram: qualidade de vida, desempenho e indicação médica. Quanto aos motivos para não praticar esportes, os mais relatados foram: falta de tempo (38,8% para os homens e 37,8% para as mulheres), não gostar (34,8% para os homens e 35,3% para as mulheres) e problemas de saúde (20,3% para os homens e 17,9% para as mulheres). O estudo mostrou os motivos mais frequentes para a prática esportiva no Brasil. Compreender esses motivos e como eles são influenciados pela idade e por nível de educação pode contribuir para melhorar estratégias para promover o esporte em países de renda média.

Abstract This article aims to describe the reasons for sport participation in the Brazilian adult population according to gender, age and schooling level. This is a cross-sectional study with data from a National Household Sample Survey - 2015. The reasons to practice or not practice sports in the previous year were obtained by questionnaire with predetermined answer options. All analyses were performed in Stata 12.1 and stratified by gender. The prevalence of sports participation for men and women were 31.7% and 16.9%, respectively. The most frequent reasons for sports participation among men were: having fun, quality of life and performance. Among women, the most frequent reasons were: quality of life, performance and medical recommendation. Regarding reasons for not practicing sports, the most reported ones were: lack of time (38.8% for men and 37.8% for women), not enjoying (34.8% for men and 35.3% for women) and health problem (20.3% for men and 17.9% for women). The study findings showed the most frequent reasons for sport participation in Brazil. Understanding these reasons and how they affect different age ranges and educational levels may contribute to improve strategic planning to promote sports in middle-income countries.

Abstract This study aimed to assess the association between oral health and rurality in an older Brazilian population. Population-based samples of 1,451 urban and 411 rural elders were obtained from two databases. Several oral health and related measures, including the number of teeth lost, use of dental prostheses, dental visits, self-reported oral health, and perceived need for a dental prosthesis, were compared. Oral health-related information was obtained by a trained research team with interviews conducted in the individuals’ homes. Regression models were used to verify the association between living in rural areas and oral health outcomes after adjusting for possible confounding factors. The elderly population mostly comprised of women in rural or urban areas, and the mean age was 70 years in both locations. Less-educated individuals (without or with complete elementary schooling) were more common in rural regions than in urban areas. After adjustment for socioeconomic characteristics, living in rural areas was associated with a lower perceived need for dental prostheses (PR 0.68, 95% CI 0.56–0.84), poor self-reported oral health (OR 1.24; 95% CI 1.05–1.46), and having fewer teeth (β -1.31; 95% CI -2.18 to -0.45). The place of residence had a significant impact on oral health indicators, with rurality negatively influencing oral health. These findings suggest that preventive and curative strategies for dental services may be needed for the Brazilian rural population.

RESUMO: Objetivos: O objetivo do presente estudo foi descrever o impacto da pandemia de covid-19 na Atenção Primária à Saúde (APS) Brasileira. Métodos: Estudo ecológico retrospectivo realizado com dados de municípios brasileiros, obtidos nos sistemas de informação do Sistema Único de Saúde (SUS). Os desfechos do estudo foram as consultas médicas, procedimentos de pré-natal e tratamento de diabetes. A exposição foi a ocorrência da pandemia de covid-19, a partir do primeiro caso notificado no Brasil. Regressões binomiais negativas de efeitos mistos multinível foram utilizadas para analisar a associação entre o número de procedimentos por 10.000 habitantes e a pandemia de covid-19. Resultados: Dados de 5.564 municípios brasileiros foram incluídos no presente estudo. Em relação à consulta médica, a maior redução devido à pandemia em curso ocorreu em maio (IRR = 0,27, IC95% 0,24 - 0,30). Para os procedimentos de pré-natal, a redução foi de 65% (IRR = 0,35, IC95% 0.32 - 0.38), também em maio. Ainda assim, os procedimentos de tratamento do diabetes tiveram maiores reduções em abril (IRR = 0,24, IC95% 0,11 - 0,53) e maio (IRR = 0,19, IC95% 0,09 - 0,43) de 2020. De fevereiro a dezembro de 2020, a pandemia de covid-19 impactou significantemente o total de procedimentos avaliados. Conclusão: Os achados mostraram uma redução de procedimentos de pré-natal, diabetes e consultas médicas realizadas na Atenção Primária à Saúde (APS) do Brasil, após o início da pandemia de covid-19.

ABSTRACT: Objectives: The purpose of this study was to describe the impact of the COVID-19 pandemic on Primary Health Care in Brazil. Methodology: This retrospective ecological study was carried out using Brazilian municipality data obtained from the information systems of the National Public Health System. The outcomes were medical appointments, prenatal procedures and diabetes care. The exposure variable was the occurrence of the COVID-19 pandemic, based on the first case reported in Brazil. Multilevel mixed-effects negative binomial regression was used to analyze the association between the number of procedures per 10,000 inhabitants and COVID-19. Results: Data from 5,564 Brazilian municipalities were included in the present study. Regarding medical appointments, the largest reduction occasioned by the pandemic occurred in May (IRR = 0.27, 95%CI 0.24 – 0.30). Prenatal procedures were reduced by 65% (IRR = 0.35, 95%CI 0.32 – 0.38), also in May. In addition, diabetes care saw the biggest reductions in April 2020 (IRR = 0.24, 95%CI 0.11 – 0.53) and May 2020 (IRR = 0.19, 95%CI 0.09 – 0.43). From February to December 2020, the pandemic had a significant effect on the total number of procedures evaluated. Conclusion: The findings showed a reduction in prenatal procedures, diabetes and medical consultations performed in Brazil's Primary Health Care, following the onset of the COVID-19 pandemic.

Abstract: The present study aimed to estimate the impact of the COVID-19 pandemic on dental care procedures in the Public Health System in Brazil. A retrospective, ecological study was carried out, comprising 5,564 Brazilian municipalities. The number of dental procedures (per 100,000 inhabitants) performed in the Brazilian Public Health System (SUS) was the outcome. The impact of the pandemic was estimated by comparing the rate of procedures for each month of 2020 with the rates observed in the equivalent months in 2019, considering the period from March to August. Regulatory legislation regarding restrictions on dental care, issued by the state governments of 27 Brazilian federative units, was used for mediation analysis. A 55% reduction was observed in March for all procedures (IRR = 0.45, 95%CI 0.39–0.51), while in the other months, the rate of reduction remained ≥ 88%. The biggest decrease was observed in collective preventive procedures (reduction ≥99%) between April and August. Procedures that were less likely to generate aerosols (tooth extraction and prosthetic) and emergencies showed the smallest reduction. The reduction was not mediated by the restrictions imposed by state governments (p>0.05). The impact of the COVID-19 pandemic was noteworthy in terms of the decrease in the number of dental procedures carried out in the Brazilian Public Dental Service. The lack of access, the delay of elective procedures and the lack of preventive collective procedures could result in an overburdened system, post-Pandemic.

RESUMO Objetivo O objetivo deste estudo foi investigar o impacto de lesões dentais traumáticas severas na Qualidade de Vida Relacionada à Saúde Bucal (QVRSB) de crianças pré-escolares. Métodos Estudo transversal realizado com crianças de 2 a 5 anos e suas mães, na cidade de Pelotas / RS. A escala Early Childhood Oral Health Impact Scale (ECOHIS) foi aplicada para avaliar a percepção das mães sobre a QVRSB das crianças. O exame de saúde bucal incluiu traumatismo dentário, classificado como ausente / leve (fratura de esmalte apenas) ou severo, o número de dentes decíduos cariados, ausentes ou restaurados (ceo-d) e a presença de mordida aberta anterior. O impacto do traumatismo dentário severo na QVRSB foi avaliado por meio de análise de regressão logística (P <0,05). Resultados Foram incluídos 599 pré-escolares e 7,4% sofreram traumatismo dentário severo. Destes, 73,3% apresentaram impacto negativo na QVRSB (p = 0,044). Após ajustes, as crianças com traumatismo dentário severo tiveram um impacto na QVRSB 110% maior do que aquelas sem trauma / com trauma leve (OR: 2,10, IC 95% 1,01-4,35). Traumas dentais graves causaram impacto negativo nos domínios sintomas orais (OR: 2,13, IC 95% 1,10-4,14), domínio psicológico (OR: 2,13, IC 95% 1,10-4,13) e função familiar (OR: 2,79, IC 95% 1,17-6,61). Conclusão A presença de traumatismo dentário severo impacta a QVRSB de crianças pré-escolares e suas famílias.

ABSTRACT Objective: The aim of this study was to investigate the impact of severe traumatic dental injuries on the Oral Health related Quality of Life (OHRQoL) of preschool children. Methods: This cross-sectional study was conducted with children aged 2 to 5 years and their mothers, in Pelotas/ Brazil Southern. The Early Childhood Oral Health Impact Scale (ECOHIS) was applied to assess the perception of mothers about children’s OHRQoL. Oral examination included dental trauma, categorized as absent/mild (enamel fracture only) or severe, the number of decayed, missing or restored primary teeth (dmft), and presence of anterior open bite. The impact of severe dental trauma on OHRQoL was evaluated using logistic regression analysis (P<0.05). Results: A total of 599 preschool children were included and 7.4% had severe dental trauma. Of these 73.3% showed negative impact on OHRQoL (p= 0.044). After adjustments, children with severe dental trauma had an impact in OHRQoL 110% higher than those without/with mild trauma (OR: 2.10, 95% CI 1.01-4.35). Severe dental injuries caused negative impact on the oral symptoms (OR: 2.13, 95% CI 1.10-4.14), psychological (OR: 2.13, 95% CI 1.10-4.13) and family function (OR: 2.79, 95% CI 1.17-6.61) domains. Conclusion: The presence of severe dental trauma impacts the OHRQoL of preschool children and their families.

RESUMO OBJETIVO Revisar sistematicamente as evidências da associação entre consumo de alimentos de acordo com o processamento e fatores cardiometabólicos em adultos e idosos. MÉTODOS Dois avaliadores independentes analisaram as bases de dados eletrônicas PubMed, Web of Science e Lilacs até dezembro de 2018. Os seguintes termos foram utilizados: (convenience foods OR food processing OR highly-processed OR industrialized foods OR minimally-processed OR prepared foods OR processed foods OR ultra-processed OR ultraprocessed OR ultra processed OR unprocessed) AND (metabolic syndrome OR hypertension OR blood pressure OR diabetes mellitus OR glucose OR glycaemia OR insulin OR cholesterol OR triglycerides OR blood lipids OR overweight OR obesity) AND (adult OR adults OR adulthood OR aged OR elderly OR old). Nos estudos incluídos foram avaliadas as qualidades metodológica e de evidência, além de extraídas informações para a síntese qualitativa. RESULTADOS Dos 6.423 estudos identificados após a remoção das duplicatas, onze preencheram os critérios de elegibilidade. A principal classificação de alimentos utilizada foi a Nova. O consumo de alimentos ultraprocessados foi positivamente associado com excesso de peso e obesidade, hipertensão arterial e síndrome metabólica. Todos os artigos incluídos preencheram mais de 50% dos critérios de qualidade metodológica. A qualidade de evidência foi considerada moderada para o desfecho excesso de peso e obesidade e fraca para hipertensão arterial e síndrome metabólica. CONCLUSÕES A classificação de alimentos Nova se destaca na área da epidemiologia nutricional ao avaliar os efeitos do processamento de alimentos sobre desfechos em saúde. Embora seja necessária prudência na interpretação, os resultados indicam que o consumo de alimentos ultraprocessados pode ter impacto desfavorável sobre a saúde dos indivíduos.

ABSTRACT OBJECTIVE To systematically review the evidence for the association between food consumption according to processing and cardiometabolic factors in adults and/or the elderly. METHOD Two independent evaluators analyzed the electronic databases PubMed, Web of Science and Lilacs until December 2018. We used the following terms: (convenience foods OR food processing OR highly-processed OR industrialized foods OR minimally-processed OR prepared foods OR processed foods OR ultra-processed OR ultraprocessed OR ultra processed OR unprocessed) AND (metabolic syndrome OR hypertension OR blood pressure OR diabetes mellitus OR glucose OR glycaemia OR insulin OR cholesterol OR triglycerides OR blood lipids OR overweight OR obesity) AND (adult OR adults OR adulthood OR aged OR elderly OR old). We assessed methodological and evidence qualities, and also extracted information for the qualitative synthesis from the selected studies. RESULTS Of the 6,423 studies identified after removing duplicates, eleven met the eligibility criteria. The main food classification we used was Nova. The consumption of ultra-processed foods was positively associated with overweight and obesity, high blood pressure and metabolic syndrome. All articles included met more than 50% of the methodological quality criteria. The quality of evidence was considered moderate for the outcome overweight and obesity and weak for hypertension and metabolic syndrome. CONCLUSIONS The Nova food classification stands out in the area of nutritional epidemiology when assessing the effects of food processing on health outcomes. Although caution is required in the interpretation, the results indicated that the consumption of ultra-processed foods can have an unfavorable impact in the health of individuals.

Resumo Este artigo avalia o conhecimento dos agentes comunitários de saúde em alimentação complementar e sua associação com características sociodemográficas, rotinas de trabalho e descreve os recursos disponíveis nas unidades básicas de saúde para que tenham domínio neste tema. Foi aplicado um questionário ao responsável do serviço de saúde e outro aos agentes comunitários de saúde, este último composto pelo teste de conhecimento que permitiu o cálculo de escores conforme o número de acertos em questões de múltipla escolha. Houve associação positiva com idade, tempo de profissão, visitas domiciliares a crianças com até 24 meses, realizar orientações e buscar informações sobre alimentação complementar com o conhecimento em alimentação nos primeiros 24 meses de vida. Evidenciou-se desacordo entre as respostas do serviço de saúde e dos agentes comunitários de saúde quanto a treinamentos, materiais governamentais e acompanhamento do crescimento infantil. Verificou-se maior domínio em aleitamento materno em relação à alimentação complementar, portanto, a unidade básica de saúde deve oferecer respaldo e recursos que ampliem o conhecimento em alimentação complementar, mediante treinamentos e acesso facilitado aos materiais governamentais.

Abstract This paper evaluates the knowledge of community health workers in complementary feeding and their association with sociodemographic characteristics, work routines and describes the resources available in primary care facilities to master this topic. We applied questionnaires to the responsible for health services and to community health workers, the latter consisting of a knowledge test that allowed the calculation of scores according to the number of correct answers in multiple-choice questions. There was a positive association with age, length of service, home visits to children under 24 months, providing guidance or seeking information about complementary feeding with the knowledge in feeding in the first 24 months of life. There were discrepant responses by health services and the community health workers regarding training, government materials and child growth monitoring. Greater mastery was noted in breastfeeding in relation to complementary feeding. Therefore, primary care facilities should provide support and resources to increase knowledge in complementary feeding through training and access to government materials.
