Absenteeism due to mental and behavioral disorder in employees of a federal university.

Introduction: Mental and behavioral disorders (MBD) are one of the main causes of absence from work in Brazil and worldwide. Objectives: To analyze the prevalence of absence from work according to the International Classification of Diseases, 10th revision, with stratification of disease defined as "Mental and Behavioral Disorders", in permanent employees of the Federal University of Ouro Preto and its relationships with sociodemographic and occupational determinants, during the period from 2011 to 2019. Methods: An epidemiological, descriptive, and analytical study, with a cross-sectional design and quantitative approach was conducted using primary and secondary data. The population consisted of federal public sector workers who were granted ML to treat their own health during a 9-year period. Analyses were performed using descriptive and bivariate statistics. The Wilcoxon (Mann-Whitney) and Poisson tests were used to assess the existence of associations between variables. Results: 733 medical records of employees eligible according to the inclusion criteria were analyzed. There was a rising trend in ML rates over the 9-year period. Of the sample, 23.2% (n = 170) were absent from work due to mental and behavioral disorders - females accounted for 57.6% and administrative technicians in education for 62.3%. In the multivariate analysis (Poisson test), only the outcome "time of first ML due to mental and behavioral disorders" was associated with the variable "time working at the Universidade Federal de Ouro Preto". Conclusions: The high prevalence of mental and behavioral disorders found in this investigation is an alert to the magnitude of the problem, highlighting the urgency of implementing measures to detect psychosocial risk factors, whether associated with work or not.

Introdução: Os transtornos mentais e comportamentais (TMC) configuram como uma das principais causas de afastamento do trabalho no Brasil e no mundo. Objetivos: Analisar a prevalência do afastamento do trabalho de acordo com a Classificação Internacional de Doenças e Problemas Relacionados à Saúde - 10ª Revisão, com estratificação da doença definida como "Transtornos Mentais e Comportamentais" dos servidores efetivos da Universidade Federal de Ouro Preto e sua relação com os determinantes sociodemográficos e ocupacionais, no período de 2011 a 2019. Métodos: Estudo epidemiológico com delineamento transversal e abordagem quantitativa, realizado a partir de dados primários e secundários. A população foi composta por servidores públicos federais com licenças médicas para tratamento da própria saúde no período de 9 anos. A análise foi realizada por meio de estatística descritiva e bivariada. Utilizou-se o teste de Wilcoxon (Mann-Whitney) e de Poisson para avaliação de existência de associação entre as variáveis. Resultados: Foram analisados 733 prontuários de servidores elegíveis nos critérios de admissão. A tendência das taxas de afastamento foi de crescimento no período de 9 anos. Na amostra, 23,2% (n = 170) apresentaram afastamento do trabalho por transtornos mentais e comportamentais - o sexo feminino apresentou 57,6%, e os técnicos administrativos em educação apresentaram 62,3%. Na análise multivariada (teste de Poisson), apenas o desfecho "momento do primeiro afastamento por transtornos mentais e comportamentais" apresentou associação com a variável tempo de Universidade Federal de Ouro Preto. Conclusões: A alta prevalência de transtornos mentais e comportamentais encontrada nesta investigação alerta para a magnitude do problema, evidenciando-se a urgência da implantação de medidas de detecção de fatores psicossociais de risco associados ou não ao trabalho.

A High-Fat Diet Exacerbates the Course of Experimental Trypanosoma cruzi Infection That Can Be Mitigated by Treatment with Simvastatin.

The protozoan Trypanosoma cruzi is responsible for triggering a damage immune response in the host cardiovascular system. This parasite has a high affinity for host lipoproteins and uses the low-density lipoprotein (LDL) receptor for its invasion. Assuming that the presence of LDL cholesterol in tissues could facilitate T. cruzi proliferation, dietary composition may affect the parasite-host relationship. Therefore, the aim of this study was to evaluate myocarditis in T. cruzi-infected C57BL/6 mice-acute phase-fed a high-fat diet and treated with simvastatin, a lipid-lowering medication. Animals (n = 10) were infected with 5 × 103 cells of the VL-10 strain of T. cruzi and treated or untreated daily with 20 mg/kg simvastatin, starting 24 h after infection and fed with a normolipidic or high-fat diet. Also, uninfected mice, treated or not with simvastatin and fed with normolipidic or high-fat diet, were evaluated as control groups. Analyses to measure the production of chemokine (C-C motif) ligand 2 (CCL2), interferon- (IFN-) γ, interleukin- (IL-) 10, and tumor necrosis factor (TNF); total hepatic lipid dosage; cholesterol; and fractions, as well as histopathological analysis, were performed on day 30 using cardiac and fat tissues. Our results showed that the high-fat diet increased (i) parasite replication, (ii) fat accumulation in the liver, (iii) total cholesterol and LDL levels, and (iv) the host inflammatory state through the production of the cytokine TNF. However, simvastatin only reduced the production of CCL2 but not that of other inflammatory mediators or biochemical parameters. Together, our data suggest that the high-fat diet may have worsened the biochemical parameters of the uninfected and T. cruzi-infected animals, as well as favored the survival of circulating parasites.

Atuação de nutricionistas responsáveis técnicos pela alimentação escolar de municípios de Minas Gerais e Espírito Santo / Actions of nutritionists as the technicians responsible for school food in municipalities in the states of Minas Gerais and Espírito Santo

Resumo O nutricionista é responsável pela promoção da segurança alimentar e nutricional na alimentação escolar, contribuindo para a construção de práticas alimentares saudáveis. Neste estudo buscou-se conhecer a atuação de nutricionistas responsáveis técnicos da alimentação escolar em municípios de Minas Gerais e Espírito Santo. Foi realizado estudo de corte transversal com participação de 77 nutricionistas, incluindo análises descritivas; univariadas e análises de regressão de Poisson com variância robusta. Constatou-se o descumprimento pela maioria dos nutricionistas de diversas atribuições essenciais do programa, previstas em Lei, como produção do plano anual de trabalho, análise da composição nutricional de cardápios, elaboração de fichas técnicas de preparação, utilização do Manual de Boas Práticas de Fabricação e realização do teste de aceitabilidade. Os modelos de regressão mostraram que nutricionistas que desenvolviam plano de trabalho, avaliação nutricional e teste de aceitabilidade apresentaram maior ocorrência de realização de ações de Educação Alimentar e Nutricional. Ressalta-se necessidade imediata de adequação dos municípios à legislação vigente e implementação de ações corretivas.

Abstract The nutritionist is responsible for promoting eating and nutritional security in school food, thereby contributing to the adoption of healthy eating habits. The scope of this study was to assess the actions of nutritionists as the technicians responsible for school food in the states of Minas Gerais and Espírito Santo. A cross-sectional study was conducted with the participation of 77 nutritionists, and included descriptive, univariate, multivariate and Poisson regression analysis with robust variance. The results revealed non-compliance by the majority of nutritionists with various fundamental attributions of the program as required by law. These include the compilation of the annual work plan, analysis of the nutritional composition of menus, elaboration of technical procedures for food preparation, use of the Good Preparation Practices Manual and conducting the test of acceptability. The regression models showed that nutritionists who prepared a work plan, performed nutritional assessment and conducted tests of acceptability, perform more Food and Nutrition Education actions. These findings highlight the urgent need to bring the municipalities into line with prevailing legislation and implement corrective actions.

Estrutura da vigilância alimentar e nutricional na atenção básica em saúde no estado de Minas Gerais / Structure of the food and nutrition surveillance system in primary health care in the Minas Gerais state

A Vigilância Alimentar e Nutricional-VAN visa a monitorar o estado alimentar e nutricional da população com o propósito de prover informação contínua sobre as condições alimentares e nutricionais e seus fatores determinantes para tomada de decisão pelos gestores. As ações para sua operacionalização devem ser promovidas no âmbito da Atenção Básica do Sistema Único de Saúde, utilizando a estrutura disponível desse nível de atenção, incluindo os recursos humanos, financeiros, físicos e materiais. Este trabalho objetivou identificar e descrever a estrutura organizacional para a realização de ações de vigilância alimentar e nutricional em nível municipal, por meio de questionário estruturado, enviado aos 853 municípios de Minas Gerais, Brasil. Participaram da pesquisa 432 municípios, nos quais foi observado que a estrutura para a realização de ações de alimentação e nutrição avançou, desde a implantação da Vigilância Alimentar e Nutricional, no Sistema Único de Saúde, mas carece de adequações que possibilitem qualificar as ações de alimentação e nutrição realizadas, bem como aumentar a cobertura populacional.

The aim of the Food and Nutrition Surveillance is to monitor the food and nutritional status of the population, for decision making by managers. This enables continuous collection of information regarding food and nutritional conditions and their determining factors. To implement this system, programs should be promoted within the basic care provided by the Unified Health System (SUS) by using the structure available at this level of care that includes human, financial, and material resources. With the aid of a structured questionnaire sent to 853 municipalities in Minas Gerais, the aim of this study was to identify and describe the structure available at the municipal level for the implementation of food and nutrition surveillance programs. Around 432 municipalities participated in the survey, revealing that their structure for the implementation of food and nutrition programs, in terms of the availability of human, financial, and material resources, requiring adaptations and greater consideration by the administration.

Determinants of Iron Deficiency Anemia in a Cohort of Children Aged 6-71 Months Living in the Northeast of Minas Gerais, Brazil.

Iron deficiency anemia is one of the most common nutritional disorders worldwide. The aim was to identify the prevalence and incidence of anemia in children and to identify predictors of this condition, including intestinal parasites, social, nutritional and environmental factors, and comorbidities. A population-based cohort study was conducted in a sample of 414 children aged 6-71 months living in Novo Cruzeiro in the Minas Gerais State. Data were collected in 2008 and 2009 by interview and included socio-economic and demographic information about the children and their families. Blood samples were collected for testing of hemoglobin, ferritin and C-reactive protein. Anthropometric measurements and parasitological analyses of fecal samples were performed. To identify risk factors associated with anemia multivariate analyses were performed using the generalized estimating equations (GEE). In 2008 and 2009, respectively, the prevalence rates of anemia were 35.9% (95%CI 31.2-40.8) and 9.8% (95%CI 7.2-12.9), the prevalence rates of iron deficiency were 18.4% (95%CI 14.7-22.6) and 21.8% (95%CI 17.8-26.2), and the incidence rates of anemia and iron deficiency were 3.2% and 21.8%. The following risk factors associated with anemia were: iron deficiency (OR = 3.2; 95%CI 2.0-.5.3), parasitic infections (OR = 1.9; 95%CI 1.2-2.8), being of risk of or being a low length/height-for-age (OR = 2.1; 95%CI 1.4-3.2), and lower retinol intake (OR = 1.7; 95%CI 1.1-2.7), adjusted over time. Nutritional factors, parasitic infections and chronic malnutrition were identified as risk factors for anemia. These factors can be verified in a chronic process and have been classically described as risk factors for these conditions.

Prevalence of iron-deficiency anemia in children aged less than 60 months: A population-based study from the state of Minas Gerais, Brazil / Prevalência de anemia ferropriva em crianças menores de 60 meses: estudo de base populacional no Estado de Minas Gerais, Brasil

OBJECTIVE: To identify the prevalence of iron-deficiency anemia in children aged less than 60 months and the conditioning factors in Minas Gerais, Brazil. METHODS: This cross-sectional study conducted from February 2007 to July 2008 in Minas Gerais included a random sample of 725 male and female children aged less than 60 months. A household survey was administered to the children's parents or guardians to collect socioeconomic, demographic, food security, and the child's anthropometric data. The hemoglobin level was determined by a portable hemoglobinometer. Anemia was considered present when hemoglobin levels were below 11.0 g/dL. Statistical analyses estimated the prevalence of anemia and its association with socioeconomic, demographic, and food security-related variables. The model was adjusted by multivariate logistic regression. The significance level was set at 5% (p<0.05). RESULTS: The prevalence of anemia was 37.4%. The greatest prevalence occurred in the age group 6 to 24 months (43.0%). The associated variables were being female (PR=1.43; p<0.026); age (PR=1.53; p<0.024); and not frequenting a daycare center (PR=2.41; p<0.001). In the multivariate regression model, the variables being female and not frequenting a daycare center remained in the model. CONCLUSION: The present population-based study found that in Minas Gerais, one-third (37.5%) of the children aged less than 60 months have iron-deficiency anemia. The results show that not frequenting a daycare center and being female are risk factors for anemia. .

OBJETIVO: Identificar a prevalência de anemia em crianças menores de 60 meses e seus fatores condicionantes, em Minas Gerais. MÉTODOS: Estudo transversal com amostra probabilística de 725 crianças menores de 60 meses de idade, de ambos os sexos, realizado entre fevereiro de 2007 e julho de 2008, em Minas Gerais. Por meio de inquérito domiciliar aplicado aos responsáveis pelas crianças, foram obtidas informações sobre as condições socioeconômicas, demográficas e situação de segurança alimentar, bem como obtidas as medidas antropométricas. A dosagem de hemoglobina foi analisada em hemoglobinômetro portátil, considerando-se como anemia valor <11,0 g/ dL. A análise estatística estimou a prevalência da anemia e sua associação com condições socioeconômicas, demográficas e segurança alimentar. O modelo foi ajustado por regressão logística multivariada. Adotou-se p<0,05 como nível crítico para definir significância estatística. RESULTADOS: A prevalência de anemia foi de 37,4%. A maior prevalência ocorreu na faixa etária de 6 a 24 meses (43,0%). As variáveis associadas foram: sexo feminino (RP=1,43; p<0,026); idade (RP=1,53; p<0,024) e não frequentar creche (RP=2,41; p<0,001). No modelo de regressão multivariada, permaneceram as variáveis sexo feminino e não frequentar creche. CONCLUSÃO: O presente estudo, de base populacional, mostrou que em Minas Gerais um terço das crianças (37,5%) com menos de 60 meses de idade apresentava anemia ferropriva. Os resultados revelaram que não frequentar creche e ser do sexo feminino configuram situações de risco à ocorrência de anemia. .

Metabolic syndrome components can predict C reactive protein concentration in adolescents.

BACKGROUND: Metabolic syndrome (MS) is suggested to be associated with a low grade inflammation state, but the relationship between inflammation biomarkers and the components of metabolic syndrome in adolescents are still lacking. OBJECTIVE: To investigate the association between C-reactive protein (CRP) serum concentrations and metabolic syndrome components in adolescents. METHODS: A cross-sectional population based study was conducted. Anthropometric, biochemical and clinical data were collected from 524 adolescents (11-15 years old) randomly sampled from school population of Alegre city, Espírito Santo, Brazil. Data were analyzed by STATA version 9.0. RESULTS: Adolescents with higher values for BMI (p = 0.001) and higher body fat percentage (p = 0.003) had higher CRP concentrations than those with lower BMI and body fat percentage. CRP concentrations was directly correlated with BMI (r = 0.17, p = 0.0001), waist circumference (r = 0.15, p = 0.0005), HDL-c (r = 0.13, p = 0.003), fasting insulin (r = 0.12, p = 0.003) and systolic blood pressure (r = 0.11, p with = 0.01). In the multiple linear regression analysis BMI (r = 0.05, p = 0.002), fasting glucose (r = -0.01, p = 0.003) and HDL-c (r = 0.017, p < 0.001) were associated to CRP concentrations after adjusting for the other components of MS. CONCLUSION: The association found between individual components of MS and CRP concentrations suggests that inflammation might be an early event in the development of metabolic disorders in adolescents.

Antecedentes: El síndrome metabólico (SM) se sugiere que está asociada con un estado de inflamación crónica de bajo grado, pero la relación entre biomarcadores de inflamación crónica de bajo grado, pero la relación entre biomarcadores de inflamación y los componentes del síndrome metabólico en adolescentes son escasos. Objetivo: Investigar la asociación entre las concentraciones séricas de proteína C reactiva (CRP) y los componentes del síndrome metabólico en adolescentes. Metodología: Hemos realizado una población basada en estudio de corte transversal. Los datos antropométricos, bioquímicos y clínicos se obtuvieron de 524 adolescentes (11-15 años de edad) seleccionados al azar de la población escolar de la ciudad Alegre, Espírito Santo, Brasil. Los datos fueron analizados por STATA versión 9.0. Resultados: Los adolescentes, con valores más altos de IMC (p = 0,001) y mayor porcentaje de grasa corporal (p = 0,003) tuvieron mayores concentraciones de PCR que aquellos con menor IMC y porcentaje de grasa corporal. Las concentraciones de PCR se correlacionó directamente con el IMC (r = 0,17, p = 0,0001), la circunferencia de la cintura (r = 0,15, p = 0,0005), HDL-c (r = 0,13, p = 0,003), la insulina en ayunas (r = 0,12, p = 0,009) y la presión arterial sistólica (r = 0,11, p = a 0,01). En el análisis de regresión lineal múltiple IMC (r = 0,05, p = 0,002), la glucosa en ayunas (r = -0,01, p = 0,003) y HDL-c (r = 0,017, p < 0,001) se asociaron a las concentraciones de PCR después de ajustar por los otros componentes de SM. Conclusión: La asociación encontrada entre los componentes individuales de SM y las concentraciones de PCR sugiere que la inflamación podría ser un evento temprano en el desarrollo de trastornos metabólicos en los adolescentes.

[Iodine deficiency and associated factors in infants and preschool children in an urban community in the semiarid region of Minas Gerais State, Brazil, 2008]. / Deficiência de iodo e fatores associados em lactentes e pré-escolares de um município do semiárido de Minas Gerais, Brasil, 2008.

The aim of this study was to evaluate the prevalence of iodine deficiency in children aged 6 to 71 months in Novo Cruzeiro, Minas Gerais State, Brazil. A total of 475 children, allocated by stratified probability sampling, were analyzed with respect to the iodine concentrations in the salt consumed by the family and urinary iodine. Iodine deficiency was verified in 34.4% of the children, of which 23.5% showed slight deficiency, 5.9% moderate and 5% serious deficiency. A difference in the distribution of iodine deficiency was observed between the urban and the rural environments (p < 0.001) where average urinary iodine concentrations of 150.8 and 114.3µg/L respectively were found. A greater proportion of iodine deficiency was observed among children where the proportion of iodine in the salt consumed was below the recommended level. Although expressive, iodine deficiency in Novo Cruzeiro is not a public health problem according to World Health Organization (WHO), The limitrophe distribution of the urinary iodine associated with low iodine levels in salt suggests that efforts to control this deficiency are not yet complete.

Concentração de sódio e glicose em soro de reidratação oral preparado por Agentes Comunitários de Saúde / Sodium and glucose concentration in therapeutical solution for oral rehydration prepared by Community Health Agents

A diarreia infantil é importante causa de morbimortalidade, sendo indicativo para terapia de reidratação oral (TRO). Este estudo objetivou avaliar o teor de sódio e glicose em soro de reidratação oral preparado por Agentes Comunitários de Saúde (ACS) que atuam em Unidades Básicas de Saúde (UBS), caracterizando o perfil e o conhecimento destes sobre a TRO. Após responderem questionário com informações profissionais e sobre a TRO, os ACS a prepararam por três métodos. O teor de glicose e de sódio das TRO foi determinado e comparado ao proposto pela OMS. Na análise estatística foram utilizados ANOVA, Tukey e odds ratio. Participaram do estudo 52 ACS, majoritariamente mulheres e com ensino médio completo (90,4 por cento). A adequação da TRO foi de 3,9; 9,8 e 28,9 por cento para a colher caseira, colher medida e punhado pitada, respectivamente. O preparo da TRO com a colher caseira resultou em 88,0 por cento das amostras com teor de sódio perigoso à saúde (>101 mmol/L). Entre os ACS, 38,5 por cento tinham menos de 2 anos de trabalho, com risco 4,8 vezes maior de preparar TRO inadequada em sódio. Os ACS referiram indicar a TRO no tratamento da diarreia infantil, desconhecendo efeitos colaterais do preparo inadequado. A composição da TRO produzida pelos ACS foi inadequada em todos os métodos. É recomendável treinamento dos ACS no preparo da TRO.

Infant Diarrhea is a major cause of morbidity and mortality in children and oral rehydration therapy (ORT) is required. This study evaluates the composition of ORT prepared by Community Health Agents (CHAs) working in Basic Health Units, assessing their profile and knowledge about ORT. After the CHAs answer specific questions, they are invited to prepare ORT using three methods. Glucose and sodium levels were then quantified and compared with WHO recommendations. ANOVA, Tukey and odds ratio were used for statistical analysis. 52 CHAs participated, mainly females, and 90.4 percent with full high school education. The adequacy of the ORT was 3.9; 9.8 and 28.9 percent for table spoon, measuring spoon and pinch and scoop, respectively. The ORT preparation by table spoon resulted in 88 percent of samples with dangerous levels of sodium (>101mmol/L). 38.5 percent of the CHAs had less than 2 years experience, leading to a 4.8 times greater risk of preparing ORT with high sodium. The CHAs indicated ORT as a treatment for diarrhea, though they were unaware of the side effects of inadequate preparation. The composition of the ORT produced by the CHAs was inadequate in all methods tested. The CHAs revealed a lack of knowledge of the side effects iof ORT with inadequate salt levels. The recommendation is to train the CHAs in ORT preparation.

O objetivo do estudo foi avaliar a prevalência de deficiência de iodo em crianças de 6 a 71 meses em Novo Cruzeiro, Minas Gerais, Brasil. Foram analisadas 475 crianças alocadas por amostragem probabilística estratificada em relação às concentrações de iodo no sal de consumo familiar e excreção urinária de iodo. Observou-se excreção deficiente de iodo em 34,4 por cento das crianças; entre as quais, 23,5 por cento apresentaram deficiência leve; 5,9 por cento, moderada; e 5 por cento, grave. Diferença na distribuição da deficiência de iodo urinário foi constatada entre o meio urbano e rural (p < 0,001), registrando concentrações medianas de iodúria de 150,8µg/L e 114,3µg/L, respectivamente. Observou-se alta proporção de deficiência entre crianças cujo teor de iodo no sal de consumo encontrava-se abaixo da recomendação. A deficiência de iodo em Novo Cruzeiro não constitui problema de saúde pública segundo a Organização Mundial da Saúde (OMS), embora apresente prevalência ainda expressiva. A distribuição limítrofe de iodúria associada a baixos níveis de iodo no sal sugere que as ações de controle dessa carência ainda não são completas no país.

The aim of this study was to evaluate the prevalence of iodine deficiency in children aged 6 to 71 months in Novo Cruzeiro, Minas Gerais State, Brazil. A total of 475 children, allocated by stratified probability sampling, were analyzed with respect to the iodine concentrations in the salt consumed by the family and urinary iodine. Iodine deficiency was verified in 34.4 percent of the children, of which 23.5 percent showed slight deficiency, 5.9 percent moderate and 5 percent serious deficiency. A difference in the distribution of iodine deficiency was observed between the urban and the rural environments (p < 0.001) where average urinary iodine concentrations of 150.8 and 114.3µg/L respectively were found. A greater proportion of iodine deficiency was observed among children where the proportion of iodine in the salt consumed was below the recommended level. Although expressive, iodine deficiency in Novo Cruzeiro is not a public health problem according to World Health Organization (WHO), The limitrophe distribution of the urinary iodine associated with low iodine levels in salt suggests that efforts to control this deficiency are not yet complete.

[Sodium and glucose concentration in therapeutical solution for oral rehydration prepared by Community Health Agents]. / Concentração de sódio e glicose em soro de reidratação oral preparado por Agentes Comunitários de Saúde.

Infant Diarrhea is a major cause of morbidity and mortality in children and oral rehydration therapy (ORT) is required. This study evaluates the composition of ORT prepared by Community Health Agents (CHAs) working in Basic Health Units, assessing their profile and knowledge about ORT. After the CHAs answer specific questions, they are invited to prepare ORT using three methods. Glucose and sodium levels were then quantified and compared with WHO recommendations. ANOVA, Tukey and odds ratio were used for statistical analysis. 52 CHAs participated, mainly females, and 90.4% with full high school education. The adequacy of the ORT was 3.9; 9.8 and 28.9% for table spoon, measuring spoon and pinch and scoop, respectively. The ORT preparation by table spoon resulted in 88% of samples with dangerous levels of sodium (≥101 mmol/L). 38.5% of the CHAs had less than 2 years experience, leading to a 4.8 times greater risk of preparing ORT with high sodium. The CHAs indicated ORT as a treatment for diarrhea, though they were unaware of the side effects of inadequate preparation. The composition of the ORT produced by the CHAs was inadequate in all methods tested. The CHAs revealed a lack of knowledge of the side effects iof ORT with inadequate salt levels. The recommendation is to train the CHAs in ORT preparation.

Association between nutritional status, environmental and socio-economic factors and Giardia lamblia infections among children aged 6-71 months in Brazil.

A cross-sectional study was conducted on a randomised sample of 405 children aged 6-71 months in Brazil to investigate the association between nutritional status, environmental and socio-economic factors and Giardialamblia infection. Data collection entailed an interview, anthropometric measurements and the collection of faeces and venous blood samples. The analysis was performed using multivariate logistic regression. The prevalence rate for G. lamblia was 26.3%. Nutritional status evaluation showed that 7.9% of the children had chronic malnutrition and 11.1% had acute malnutrition. The risk factors associated with infection by G. lamblia were an age of 2 years or older [odds ratio (OR)=2.4], living in a two-bedroom house or smaller (OR=2.3), living among a family of five or more people (OR=2.4) and living in a house without access to a sewerage system (OR=2.1). Non-participation in the social service programme was associated with a lower risk of infection (OR=0.2). The model adjusted for age, including only biochemical and nutritional variables, showed weak associations with G. lamblia infection for two variables: inadequate animal protein intake according to the Dietary Reference Intake recommendation and low haemoglobin concentration. The sociodemographic and environmental risk factors classically described were associated with G. lamblia infection, but nutritional variables were only weakly associated with it.
