ABSTRACT BACKGROUND: Few food frequency questionnaires (FFQ) have been validated for pregnant women, particularly those in small- and medium-sized cities in different regions of Brazil. OBJECTIVES: To validate and calibrate a semiquantitative FFQ for pregnant women. DESIGN AND SETTING: The study was validated with a sample of 50 pregnant women (≥ 18 years) enrolled in Brazilian prenatal services. METHODS: An FFQ and a 24-hour recall were used to evaluate dietary intake. Dietary variables were tested for normality and log-converted when asymmetrical. Pearson's Correlation Coefficient was used to validate the questionnaire. Linear regression was applied to extract calibration factors. All variables underlying the consumption analysis were adjusted for energy. RESULTS: The mean age of the pregnant women was 26 years ± 6.2 years; 58% were in their first trimester, and 30% were identified as overweight/obese. The Pearson correlation analysis results indicated that the FFQ overestimated energy and nutrient intake, whose coefficients ranged from −0.15 (monounsaturated fat) to 0.50 (carbohydrate). Adjusting for energy reduced the mean values of intake coefficients, which now ranged from −0.33 (sodium) to 0.96 (folate). The calibration analysis results indicated variation in the coefficients from −0.23 (sodium) to 1.00 (folate). Calibration produced satisfactory coefficients for the FFQ compared with the reference standard for energy, macronutrients, monounsaturated fat, cholesterol, vitamins B12/C, folate, sodium, iron, and calcium. CONCLUSIONS: After validating and calibrating tests, we observed that the FFQ was adequately accurate for assessing the food consumption of the pregnant women in this study.

ABSTRACT BACKGROUND: Weight retention during the post-partum period is associated with excessive weight gain. OBJECTIVES: To investigate factors associated with maternal weight retention at six months post-partum (PPWR). DESIGN AND SETTING: A prospective cohort study was conducted with 127 women monitored using prenatal services. METHODS: The outcome variable was represented by post-partum maternal weight retention and calculated as the difference between the mother’s weight at sixth month post-partum and her pregestational weight. RESULTS: The mean age of the pregnant women was 26.7 ± 5.25 years old, and the post-partum maternal weight retention was 46.5%. The proximal determinants showed a direct association with PPWR after adjusting for the distal and intermediate variables: excessive gestational weight gain (odds ratio [OR]:3.34; confidence interval [CI]:1.16–9.59), greater adhesion to dietary intake pattern 2 (composed of red meats and derivatives, eggs, industrialized foods, and coffee) (OR:2.70; CI:1.16–6.32), and the absence of exclusive maternal breastfeeding in the first month (OR:3.40; CI:1.27–9.12), as well as primiparity (OR:2.36; CI:1.00–5.55), an intermediate determinant. Insufficient weight gain in pregnancy was inversely associated with the outcome (OR:0.35; CI:0.31–0.93). CONCLUSIONS: Among the hierarchical determinants, proximal factors were interrelated with maternal weight retention, indicating that excessive total weight gain, an inadequate dietary intake pattern, and the absence of exclusive maternal breastfeeding in the first month of life work as dampeners of the return to pre-gestational weight. Prepartum and post-partum care interventions can contribute to reducing excess weight in women. BACKGROUND postpartum post partum OBJECTIVES PPWR. .

Objective: To analyze temporal trends and spatial patterns of mortality from neglected tropical diseases (NTD) in Piauí, 2001-2018. Methods: Mixed ecological study, with hazard ratio (RR) calculation,spatio- temporal trend analysis, Poisson regression with inflection points, using data from the Mortality Information System. Results: There were 2,609 deaths due to NTD in the period (4.60/100,000 inhabitants), 55.2% due to Chagas disease. There was a higher risk of death in men (RR=1.76 – 95%CI 1.25;2.46), aged ≥60 years (RR=40.71 – 95%CI 10.01;165.53), municipalities with vulnerability average social (RR=1.76 – 95%CI 1.09;2.84), smaller population size (RR=1.99 – 95%CI 1.28;3.10) and Cerrados macro-region (RR=4.51-95%CI 2.51;8.11). There was an upward trend in mortality rates from 2001-2008 and a reduction from 2009- 2018. Conclusion: Mortality due to NTD in Piauí remains high, particularly due to Chagas disease, among groups with greater vulnerability, with concentration of higher rates in the southwest of the semi-arid macro-region, northeast and south of the Cerrados.

Caracterizar a magnitude das internações hospitalares e custos por doenças tropicais negligenciadas, suas tendências temporais e padrões espaciais no Piauí, Nordeste do Brasil, 2001-2018. Estudo ecológico misto, com cálculo de risco relativo (RR) e análise de tendência temporal por regressão de Poisson, pontos de inflexão, utilizando-se dados de Autorizações de Internações Hospitalares por doenças tropicais negligenciadas via Sistema de Informações Hospitalares do Sistema Único de Saúde (SIH/SUS). Verificaram-se 49.832 internações hospitalares por doenças tropicais negligenciadas (taxa: 86,70/100 mil habitantes; IC95%: 83,47; 89,93) no período, principalmente dengue (78,2%), leishmanioses (8,6%) e hanseníase (6,4%). O custo total foi de R$ 34.481.815,43, sendo 42,8% de média complexidade. Maiores riscos de hospitalizações ocorreram em: pessoas ≥ 60 anos (RR = 1,8; IC95%:1,5; 2,2), etnia/cor parda (RR = 1,7; IC95%: 1,1; 2,4), residentes em municípios de média vulnerabilidade social (RR = 1,5; IC95%: 1,3; 1,6) e porte populacional (RR = 1,6; IC95%: 1,4; 1,9). A tendência temporal foi de redução nas taxas de internações hospitalares por doenças tropicais negligenciadas, 2003-2018 (variação percentual anual - APC: -10,3; IC95%: -14,7; -5,6). O padrão espacial apresentou aglomerados com maiores taxas de internações hospitalares nos municípios limítrofes ao sul da macrorregião Meio-norte, norte do Semiárido e sul dos Cerrados. O Piauí persiste com elevadas taxas de hospitalizações e custos por doenças tropicais negligenciadas. Apesar da redução nas tendências temporais, o conhecimento de sua carga, seus grupos populacionais e municípios de maior risco e vulnerabilidade reforçam a importância do monitoramento e fortalecimento das ações de controle para manutenção na redução da carga e custos de internações hospitalares por doenças tropicais negligenciadas no estado.

To characterize the magnitude of hospital admissions and costs of patients with neglected tropical diseases, their time trends, and spatial patterns in Piauí, in the Northeast Region of Brazil, in 2001-2018. Ecological study of mixed designs, with calculation of relative risk (RR), time-trend analysis by Poisson regression, and inflection points, using data from neglected tropical diseases Hospital Admission Authorizations available in the Hospital Information System of the Brazilian Unified National Health System (SIH/SUS). Data showed 49,832 hospital admissions due to neglected tropical diseases in the period (rate: 86.70/100,000 inhabitants; 95%CI: 83.47; 89.93); of these, dengue (78.2%), leishmaniasis (8.6%), and leprosy (6.4%). The total cost was BRL 34,481,815.43, 42.8% of which referred to medium complexity cases. Higher risks of hospitalization occurred among people ≥ 60 years (RR = 1.8; 95%CI: 1.5; 2.2), mixed race/color (RR = 1.7; 95%CI: 1.1; 2.4), residents of municipalities presenting medium social vulnerability (RR = 1.5; 95% CI: 1.3; 1.6), and population size (RR = 1.6; 95%CI: 1.4; 1.9). The time trend showed a reduction in hospital admissions due to neglected tropical diseases, 2003-2018 (annual percent change - APC: -10.3; 95%CI: -14.7; -5.6). The spatial pattern showed clusters with higher rates of hospital admission in border municipalities located south of the Mid-north macroregion, north of the Semiarid macroregion, and south of the Cerrados macroregion. Piauí remains with high hospital admission rates and costs for neglected tropical diseases. Despite the reduction in time trends, knowledge burden, population groups, and municipalities at greater risk and vulnerability reinforce the importance of monitoring and strengthening control actions to maintain the reduction of the burden and costs of hospital admission due to neglected tropical diseases in the state.

Abstract Objetive To analyze temporal trends and spatial patterns of mortality due to neglected tropical diseases (NTDs) in Piauí, Brazil, 2001-2018. Methods This was a mixed ecological study, with risk ratio (RR) calculation, spatiotemporal trend analysis, Poisson joinpoint regression, using data from the Mortality Information System. Results There were 2,609 deaths due to NTDs in the period (4.60/100,000 inhabitants), 55.2% were due to Chagas’ disease. There was a higher risk of death in male (RR=1.76; 95%CI 1.25;2.46), being aged ≥60 years (RR=40.71; 95%CI 10.01;165.53), municipalities with medium vulnerability social (RR=1.76; 95%CI 1.09;2.84), smaller population size (RR=1.99; 95%CI 1.28;3.10) and the Cerrados macro-region (RR=4.51; 95%CI 2.51;8.11). There was an upward trend in mortality rates from 2001-2008 and a falling trend from 2009-2018. Conclusion Mortality due to NTDs in Piauí remains high, particularly due to Chagas’ disease, among groups with greater vulnerability, with concentration of higher rates in the southwest of the Semiarid macro-region and the northeast and south of the Cerrados macro-region.

ABSTRACT Drought is a natural and recurrent phenomenon. It is considered ‘a natural disaster’ whenever it occurs in an intensive manner in highly populated regions, resulting in significant damage (material and human) and loss (socioeconomic). This paper presents the efforts developed to monitor the impact of drought in the semiarid region of Northeast Brazil. In this scope, information from different sources is compiled to support the evaluation and identification of impacted municipalities, with the main objective of supporting emergency actions to mitigate their impact. In the semiarid region of Brazil there are frequent occurrences of dry periods during the rainy season, which, depending on the intensity and duration, can cause significant damage to family-farmed crops, with a farming system characterized by low productivity indices. However, rain-fed agriculture has great economic expression and high social importance due to the region is densely occupied, and contributes to the establishment of communities in the countryside. Specifically, in the present study, the methodology adopted to monitor the impact of agricultural droughts, including an analysis of the hydrological year 2015-2016, is presented, considering different water stress indicators for the identification of the affected municipalities and assessment of the methods and tools developed.

ABSTRACT This study discusses the climatological aspects of the most severe drought ever recorded in the semiarid region Northeast Brazil. Droughts are recurrent in the region and while El Nino has driven some of these events others are more dependent on the tropical North Atlantic sea surface temperature fields. The drought affecting this region during the last 5 years shows an intensity and impact not seen in several decades in the regional economy and society. The analysis of this event using drought indicators as well as meteorological fields shows that since the middle 1990s to 2016, 16 out of 25 years experienced rainfall below normal. This suggests that the recent drought may have in fact started in the middle-late 1990s, with the intense droughts of 1993 and 1998, and then the sequence of dry years (interrupted by relatively wet years in 2007, 2008, 2009 and 2011) after that may have affected the levels of reservoirs in the region, leading to a real water crisis that was magnified by the negative rainfall anomalies since 2010.

Introduction: the nutritional panorama in Brazil indicates that the dietary patterns of the population is characterized by the increasing inclusion of saturated and trans fats, sodium, sugars, soft drinks. This epidemiological and nutritional challenges reflects in the patterns of illness and death. Objective: this study aims to identify patterns of food consumption and dietary changes in the first and third trimester of pregnancy. Methodology: this is a prospective cohort study involving 185 pregnant women in the State of Bahia, from 2012 to 2013. We used a food frequency questionnaire to assess dietary intakes. To identify the dietary pattern, the principal components factor analysis was adopted. We used the Pearson correlation test to identify the correlation between the patterns extracted in each trimester. Results: four patterns of food consumption during pregnancy were identified. We observed changes in the eating patterns over the trimesters evaluated, especially for the food groups of fruit, coffee, fats, fried snacks, sugar and sweets. Discussion: these dietary changes throughout the pregnancy accompany the physiological changes of each period of the pregnancy. In the first trimester, symptoms of nausea and vomiting are common, whereas in the same period cravings is reported, which may justify the consumption of a larger quantity of food deemed unhealthy. Conclusion: it was observed that there were changes in the adoption of dietary pattern throughout the evaluated trimesters of pregnancy, especially for the groups of fruit, coffee, fats, fried snacks and sugar and sweets.

Introducción: las perspectivas de crecimiento en Brasil indican que los patrones dietéticos de la población se caracterizan por el aumento del consumo de grasas saturadas y trans, sodio, azúcares y refrescos. Este punto de vista epidemiológico y nutricional refleja el cambio en el patrón de la enfermedad y la muerte. Objetivo: este estudio tiene como objetivo identificar los patrones de consumo de alimentos y los cambios en la dieta en el primer y tercer trimestres del embarazo. Metodología: se trata de un estudio de cohorte prospectivo de 185 mujeres embarazadas del Estado de Bahía, a partir de 2012 a 2013. Se utilizó el cuestionario de frecuencia de alimentos para evaluar la ingesta alimentaria. Para identificar la norma alimentaria se adoptó el análisis factorial de componentes principales. Se utilizó la prueba de correlación de Pearson para identificar la correlación entre los patrones extraídos en cada trimestre. Resultados: se identificaron cuatro patrones de consumo de alimentos durante el embarazo. Hemos observado cambios en los patrones de alimentación durante los trimestres evaluados, especialmente para los grupos de frutas, café, grasas, frituras, azúcar y dulces. Discusión: estos cambios en la dieta durante el embarazo acompañan a los cambios fisiológicos de cada embarazo. En el primer trimestre son síntomas comunes las náuseas y los vómitos; por otro lado, también se manifiesta antojos en el mismo periodo, lo cual puede justificar el consumo de mayor cantidad de alimentos considerados saludables. Conclusion: se observaron cambios en el patrón alimentario a lo largo de los diversos trimestres del embarazo examinados, especialmente para los grupos de frutas, café, grasas, frituras, azúcar y dulces.

OBJETIVO: Descrever e comparar a percepção materna e a autopercepção da criança/adolescente do seu estado nutricional, identificando fatores associados a erro na percepção. MÉTODOS: Estudo transversal realizado em Salvador (BA) com 1.741 estudantes entre 6 e 19 anos, classificados de acordo com os percentis do índice de massa corporal (IMC) em baixo peso (IMC < p5), eutróficos (p5 ≤ IMC < p85), risco para sobrepeso (p85 ≤ IMC < p95) e sobrepeso (IMC > p95). Perguntas acerca da percepção do peso, padrão de atividade física e realização de dieta foram respondidas por alunos e genitoras. Foram avaliados, através de análise multivariada, fatores associados a erro na autopercepção e percepção materna. RESULTADOS: Houve acerto de 64,7% para a autopercepção e de 75,3% para a percepção das genitoras. O principal fator associado a erro na autopercepção foi a faixa etária entre 6 e 9 anos (OR = 1,59; IC95% 1,15-2,20). Entre as meninas, ter excesso de peso e fazer atividade física foram as características associadas à melhor percepção. Para os meninos, a presença de excesso de peso resultou em maior risco de erro na autopercepção. Entre as genitoras, filho com excesso de peso (OR = 3,02; IC95% 2,05-4,46) e faixa etária de 6 a 9 anos (OR = 1,88; IC95% 1,28-2,76) foram os fatores associados a erro na percepção. CONCLUSÃO: A falta de percepção adequada do peso ocorreu com muita freqüência entre as crianças e suas genitoras, em especial quando havia excesso de peso, fatores que podem representar obstáculos ao correto reconhecimento de alterações nutricionais.

OBJECTIVE: To describe and compare maternal perception and the self-perception of children/adolescents of their nutritional status, identifying factors associated with incorrect perceptions. METHODS: Cross-sectional study carried out in Salvador, BA, Brazil with 1,741 students aged 6 to 19 years, classified according to body mass index (BMI) percentiles as underweight (BMI < p5), well-nourished (p5 ≤ BMI < p85), at risk of overweight (p85 ≤ BMI < p95) or overweight (BMI > p95). Students and their mothers answered questions on perception of weight, patterns of physical exercise and dieting. By means of multivariate analysis, factors associated with incorrect maternal and self- perceptions were analyzed. RESULTS: Self-perceptions were correct in 64.7% of cases and 75.3% of maternal perceptions were correct. The principal factor associated with incorrect self-perception was age between 6 and 9 years (OR = 1.59; 95%CI 1.15-2.20). Among girls, being overweight and practicing physical exercise were characteristics associated with better perception. For boys, the presence of overweight resulted in an increased risk of incorrect self-perception. Among mothers, having an overweight child (OR = 3.02; 95%CI 2.05-4.46) and a child aged from 6 to 9 years (OR = 1.88; 95%CI 1.28-2.76) were associated with incorrect perception. CONCLUSIONS: A failure to correctly perceive weight was very frequent among children and their mothers, especially when children were overweight. These factors could represent obstacles to correctly recognizing nutritional abnormalities.
