Effects of exergaming on the microcirculation of adolescents with overweight or obesity-a clinical trial efficacy.

To assess the effect of exergaming on the microcirculation function of adolescents with overweight or obesity, this non-randomized clinical trial efficacy was conducted with 61 adolescents aged between 10 and 16 years. The intervention group (n = 31) performed exergaming three times per week for 8 weeks. Both groups received guidelines for a healthy diet and staying physically active. Microcirculation was assessed using a laser Doppler flowmetry (LDF) at baseline and after intervention. Primary outcomes derived from LDF assessment included resting flow, maximum flow, maximum/resting flow ratio, area under hyperemia, and post-occlusive reactive hyperemia (PORH). Secondary outcomes were body mass index and systemic blood pressure. Unpaired Student's t test compared intergroup analyses, and paired Student's t test compared intragroup analyses. The significance was set at 5%. Statistical analysis intergroup and intragroup was done by fitting a two-way mixed effects model. Microcirculation was similar between groups. Maximum flow (109.0 ± 38.3 versus 124.6 ± 43.0, P = 0.022), area under hyperemia (1614 ± 472 versus. 1755 ± 461, P = 0.023), and PORH (2.18 ± 0.49 versus 2.01 ± 0.52, P = 0.031) were statistically different after intervention. Body mass index decreased in intervention (24.5 ± 3.8-24.1 ± 4.0 kg/m2, P = 0.002) and control (25.2 ± 3.2-25.1 ± 3.3 kg/m2, P = 0.031) groups. Systolic blood pressure decreased significantly in the intervention group (110 ± 10-106 ± 9 mm Hg; P = 0.041) but not diastolic blood pressure (66.0 ± 7-68.8 ± 8 mm Hg; P = 0.089). Exergaming for 8 weeks led to improvements in the microcirculation function in adolescents with overweighed or obesity. Clinical trials: NTC03532659.

Maternal mortality committee and death surveillance in Recife in improving information: ex-ante and ex-post evaluation / Comitê de mortalidade materna e a vigilância do óbito em Recife no aprimoramento das informações: avaliação ex-ante e ex-post

Abstract Objectives: to evaluate the contribution of the Maternal Mortality and Death Surveillance Committee for women of childbearing age (WCA) and maternal mortality in the magnitude of maternal mortality and in the qualification of the causes of death in Recife, Brazil. Methods: ex ante/ex post evaluation, ecological, of the annual indicators of mortality of WCA, maternal and case study of declared maternal deaths according to causes of death before and after surveillance. Deaths of WCA (2010 and 2017) were analyzed. The percentage of investigation of deaths of WCA was calculated; their rates and maternal mortality ratio (MMR) were estimated; the groups of causes of death, classification of death, the moment of death, the proportional variation before and after surveillance, and the relocation of the causes after this process were described. Results: 4.327 (97.0%) of deaths of WCA were investigated (increase of 40.7% of maternal deaths) and MMR of 62.9/100 thousand live births. Improved notifications of immediate/late (75.0%) and remote (300.0%) postpartum; there was a difference in direct obstetric causes, total maternal deaths and late maternal death (p<0.001). Conclusion: the surveillance and the Maternal Mortality Committee showed potential in identifying the magnitude and qualification of causes of maternal death in order to propose the interventions directed to obstetric care.

Excess Weight among Survivors of Acute Lymphoblastic Leukemia Survivors Treated at a Center in Northeast Brazil.

Therapeutic advances in the treatment of acute lymphoblastic leukemia (ALL) have increased the number of survivors but have promoted the development of long-term side effects, the best documented of which is obesity. The present retrospective case series analyzed data collected at diagnosis, end of treatment, and last follow-up visit of 210 ALL survivors treated between August 2005 and October 2014. Clinical and anthropometric data were collected from medical records. The nutritional diagnosis was based on z-scores of height-for-age (H/AZ) and body mass index-for-age (BMI/AZ) for males and females provided by the World Health Organization. H/AZ decreased and BMI/AZ increased between baseline and end of treatment, followed by H/AZ catch-up at follow-up. The prevalence of excess weight on the three occasions was 24.3%, 38.3, and 43.3%, respectively. Baseline excess weight (adjusted OR: 12.2; 95% CI: 5.5-27.0) and the ALL risk group (adjusted OR: 2.89; 95% CI: 1.1-7.6) were independently associated with excess weight at the end of treatment, whereas baseline excess weight (adjusted OR: 8.50; 95% CI: 3.93-18.40) and linear growth (adjusted OR: 2.02; 95% CI: 1.05-3.88) were independently associated with excess weight at follow-up. The frequency of excess weight had increased significantly by the end of treatment and persisted at follow-up. Baseline excess weight was the main factor associated with excess weight at the end of treatment and follow-up.

Anemia in pregnant women according to two different assessment criteria (WHO versus CDC).

OBJECTIVE: To determine the prevalence of anemia among pregnant women and the associated factors and perinatal outcomes according to two different diagnostic criteria: the WHO criterion and the US Center for Disease Control and Prevention (CDC) criterion. METHODS: Cohort study, operationalized through a database. The sample comprised 781 pregnant women who had laboratory data regarding hemoglobin levels during the second trimester of pregnancy. Anemia was diagnosed when hemoglobin was less than 11 g/dl according to WHO and less than 10.5 g/dl according to CDC. Factors possibly associated with anemia were identified by adjusting Poisson univariate and multivariate regression models. To analyze the association between perinatal outcomes and anemia, the χ2 test and Fisher exact test were performed. RESULTS: The prevalence of anemia was 22.9% according to WHO and 10.9% according to CDC. A significantly higher risk of low birth weight was found in children of women with anemia, regardless of the diagnostic criteria used, while a greater risk of having a small-for-gestational-age newborn was seen only when the CDC criterion were applied. CONCLUSION: Anemia during pregnancy remains an important public health issue, but its magnitude may be overestimated by overly sensitive assessment criteria.

Impact of COVID-19 on immunization of Brazilian infants.

OBJECTIVE: To examine recent vaccination trends among Brazilian children during their first year of life, and the impact of the coronavirus disease 2019 (COVID-19) pandemic on these trends. METHODS: Monthly vaccination and birth data from the DATASUS (Department of Informatics of the Unified Health System) database of the Ministry of Health of Brazil were obtained from January 2017 to December 2020. Interrupted time series analysis was used to compare vaccination trends before and after March 2020, when isolation measures were first implemented in Brazil. RESULTS: There was no strong evidence of a significant change in trends during the study period, or before and during the pandemic at national level. However, the mean number of vaccinations per child was 10.6, which is lower than the 13 doses expected under the immunization schedule. CONCLUSIONS: Although the pandemic did not appreciably impact on vaccinations, incomplete immunization among children aged <1 year in Brazil is cause for concern. A potential impact of the COVID-19 pandemic on specific antigens or regional and sociodemographic disparities in vaccinations cannot be ruled out without further research.

Temporal Validation of a Predictive Score for Death in Children with Visceral Leishmaniasis.

OBJECTIVES: To perform a temporal validation of a predictive model for death in children with visceral leishmaniasis (VL). METHODS: A temporal validation of a children-exclusive predictive model of death due to VL (Sampaio et al. 2010 model), using a retrospective cohort, hereby called validation cohort. The validation cohort convenience sample was made of 156 patients less than 15 years old hospitalized between 2008 and 2018 with VL. Patients included in the Sampaio et al. 2010 study are here denominated derivation cohort, which was composed of 546 patients hospitalized in the same hospital setting in the period from 1996 to 2006. The calibration and discriminative capacity of the model to predict death by VL in the validation cohort were then assessed through the procedure of logistic recalibration that readjusted its coefficients. The calibration of the updated model was tested using Hosmer-Lemeshow test and Spiegelhalter test. A ROC curve was built and the value of the area under this curve represented the model's discrimination. RESULTS: The validation cohort found a lethality of 6.4%. The Sampaio et al. 2010 model demonstrated inadequate calibration in the validation cohort (Spiegelhalter test: p=0.007). It also presented unsatisfactory discriminative capacity, evaluated by the area under the ROC curve = 0.618. After the coefficient readjustment, the model showed adequate calibration (Spiegelhalter test, p=0.988) and better discrimination, becoming satisfactory (AUROC = 0.762). The score developed by Sampaio et al. 2010 attributed 1 point to the variables dyspnea, associated infections, and neutrophil count <500/mm3; 2 points to jaundice and mucosal bleeding; and 3 points to platelet count <50,000/mm3. In the recalibrated model, each one of the variables had a scoring of 1 point for each. CONCLUSION: The temporally validated model, after coefficient readjustment, presented adequate calibration and discrimination to predict death in children hospitalized with VL.

Fat Distribution among Children Born Extremely Low Birth Weight and Very Low Birth Weight: A Cohort Study.

Background: Fat distribution is associated with chronic diseases and birth weight may influence fat distribution throughout life. Our aim was to compare fat distribution in children born extremely low birth weight (ELBW) and very low birth weight (VLBW). Methods: This retrospective cohort study evaluated children born ELBW and VLBW around the 7th year of life. Fat distribution was assessed by ultrasonography measurements of abdominal subcutaneous and visceral fat thickness. Multiple linear regression analysis was performed. Results: We studied 63 children. Visceral fat thickness but not subcutaneous fat thickness was significantly increased in children born ELBW compared with children born VLBW, respectively, 3.13 (±1.08) versus 1.86 (±0.76) mm. This result remained after adjustment for age, gender, and BMI; adjusted coefficient 0.118, 95% confidence interval 0.009-0.227, p = 0.034. Conclusion: Children born ELBW seem to have increased visceral fat thickness compared with children born VLBW.

Serial Doppler velocimetry of mesenteric and portal flow in very-low-birth-weight preterm neonates with and without patent ductus arteriosus.

BACKGROUND: Very-low-birth-weight (VLBW) preterm neonates are vulnerable to patent ductus arteriosus (PDA), which might be related to high-resistance flow in the superior mesenteric artery (SMA), with decreased diastolic flow in situations of marked intestinal hypoperfusion. No previous studies have evaluated the portal vein and superior mesenteric vein (SMV) parameters to assess the PDA hemodynamic repercussions. OBJECTIVE: To assess mesenteric and portal flow in VLBW preterm neonates with or without PDA using serial Doppler ultrasonography (US). MATERIALS AND METHODS: We conducted a prospective longitudinal study on 61 VLBW preterm neonates submitted to 161 Doppler US exams, from 2 days to 20 days of age. RESULTS: All infants exhibited a progressive daily increase in the mean of the SMA diameter and systolic velocity, the portal vein diameter, the peak velocity, the mean velocity and the flow volume and of SMV diameter (P<0.05). The incidence of PDA was 37.7% (n=23) and infants with the disease revealed a smaller diameter, greater systolic velocity, lower diastolic velocity, and higher resistivity and pulsatility indices on SMA compared to those without PDA (P<0.05). Additionally, 47.8% (n=11) of infants with PDA exhibited absent or reversed end-diastolic flow in the SMA, and its resolution was seen among 54.5% (n=6) of these. Infants with PDA also exhibited lower values of portal vein diameter and flow volume and of SMV diameter (P<0.01). CONCLUSION: Doppler US enhances the understanding of mesenteric and portal flow, including the effects of PDA. The study of SMV and portal vein flow is proposed as a new parameter in PDA evaluation.

BRAzil magnesium (BRAMAG) trial: a double-masked randomized clinical trial of oral magnesium supplementation in pregnancy.

BACKGROUND: There is conflicting evidence about the role of oral magnesium supplementation in the prevention of preterm birth and related adverse outcomes. The objective of this study was to compare magnesium citrate with placebo in the prevention of adverse perinatal and maternal outcomes among women at higher risk. METHODS: This multicenter, double-masked, placebo-controlled randomized superiority clinical trial compared oral magnesium citrate 300 mg to matched placebo, from 12 to 20 weeks' gestation until delivery. This trial was completed in three centers in northeastern Brazil. Eligible women were those with a singleton pregnancy and ≥ 1 risk factor, such as prior preterm birth or preeclampsia, or current chronic hypertension or pre-pregnancy diabetes mellitus, age > 35 years or elevated body mass index. The primary perinatal composite outcome comprised preterm birth < 37 weeks' gestation, stillbirth > 20 weeks, neonatal death or NICU admission < 28 days after birth, or small for gestational age birthweight < 3rd percentile. The co-primary maternal composite outcome comprised preeclampsia or eclampsia < 37 weeks, severe gestational hypertension < 37 weeks, placental abruption, or maternal stroke or death during pregnancy or ≤ 7 days after delivery. RESULTS: Analyses comprised 407 women who received magnesium citrate and 422 who received placebo. The perinatal composite outcome occurred among 75 (18.4%) in the magnesium arm and 76 (18.0%) in the placebo group - an adjusted odds ratio (aOR) of 1.10 (95% CI 0.72-1.68). The maternal composite outcome occurred among 49 (12.0%) women in the magnesium arm and 41 women (9.7%) in the placebo group - an aOR of 1.29 (95% CI 0.83-2.00). CONCLUSIONS: Oral magnesium citrate supplementation did not appear to reduce adverse perinatal or maternal outcomes in high-risk singleton pregnancies. TRIAL REGISTRATION: ClinicalTrials.gov NCT02032186, registered January 9, 2014.

Comparison of weight estimation methods in hospitalized Brazilian children and adolescents / Comparación de métodos de estimación del peso en niños y adolescentes brasileños hospitalizados

NTRODUCTION: in emergencies or in situations involving critically ill patients, an accurate calculation of body weight is essential to ensure adequate medical care. Generally, simple techniques are used to determine weight. AIM: to evaluate the weight estimation methods Advanced Paediatric Life Support (APLS) Update, Luscombe and Owens, Best Guess, and the Broselow tape, comparing measured weight with the weight estimated by each method in hospitalized Brazilian children and adolescents. METHODS: an observational study in which anthropometric data were collected from patients of 0-14 years of age between August 2016 and January 2017. The paired t-test was used to compare the patients' measured weight with their estimated weight. The accuracy of each method was analyzed using Bland-Altman plots and Lin's concordance correlation coefficient. RESULTS: the sample consisted of 446 patients. Most of the patients were male (58.1%), of 1-5 years of age (43%) and well nourished (85%). For those under 12 months of age, the APLS Update and Best Guess methods performed best, with the difference in means of measured weight and estimated weight being 0.4 kg (p = 0.183) and -0.2 kg (p = 0.140), respectively. In the 1-5 years of age group only the APLS Update yielded satisfactory results (0.2 kg; p = 0.200). The best agreement with measured weight, according to the Bland-Altman plots and Lin's coefficient, was found for the Broselow tape (CC = 0.96). CONCLUSION: of the estimation methods evaluated the Broselow tape was the most accurate one. Further studies are required to adapt this method for use in the Brazilian population, thus ensuring its appropriate application in this country

Visceral Adipose Tissue Depth in Early Pregnancy and Gestational Diabetes Mellitus - a Cohort Study.

Some studies have suggested that abdominal visceral adipose tissue depth (VAD) measured by ultrasound in early pregnancy, may predict the future onset of gestational diabetes mellitus (GDM). Wheter this is true, independent of pre-pregnancy body mass index (BMI), has been debated, leading the current study. A prospective cohort study was completed, in which VAD was measured at around 14 weeks' gestation. GDM was later assessed by an oral glucose tolerance test at 24 to 28 weeks, according to the IADPSG criteria. Logistic regression analysis and receiver operating curve (ROC) analysis were used to estimate the predictive value of VAD, above and beyond pre-pregnancy BMI. 627 pregnant women were enrolled, and 518 completed the study. VAD was measured at a mean of 14.4 weeks' gestation. 87 women (16.8%) subsequently developed GDM. The unadjusted odds ratio (OR) for developing GDM was 1.99 (95% CI 1.59-2.46) per 1-cm increase in VAD. After adjusting for maternal BMI and age, the OR was 2.00 (95% CI 1.61 to 2.50). The ROC under the curve for developing GDM was higher for VAD (0.70, 95% CI 0.63 to 0.75) than for pre-pregnancy BMI (0.57 95% CI 0.50 to 0.64) (p < 0.001). In conclusion, higher VAD may better predict GDM than pre-pregnancy BMI.

Physical activity pattern in early pregnancy and gestational diabetes mellitus risk among low-income women: A prospective cross-sectional study.

OBJECTIVE: Gestational diabetes mellitus is increasing worldwide, mainly in developing countries, and physical activity has not been studied in gestational diabetes mellitus prevention among low-income population. This prospective cross-sectional study assessed the gestational diabetes mellitus risk related to physical activity in early pregnancy among low-income women. METHODS: A prospective cross-sectional study with 544 low-income pregnant women was conducted at the Instituto de Medicina Integral Prof. Fernando Figueira, Brazil. Gestational diabetes mellitus was diagnosed using the International Association of Diabetes and Pregnancy Study Groups criteria. Physical activity was assessed during early pregnancy using the Pregnancy Physical Activity Questionnaire and categorized as sedentary, light, moderate, or vigorous intensity. RESULTS: Gestational diabetes mellitus occurred in 95 of 544 women (17.4%). Body mass index was higher in the gestational diabetes mellitus group. Nearly half of all pregnant women studied were physically inactive, and none of them were classified as vigorous physical active. Sedentary physical activity pattern was associated with a higher odds of gestational diabetes mellitus (odds ratio = 1.8, 95% confidence interval = 1.1-2.9), which did not change after adjusting for several covariates (odds ratio = 1.9, 95% confidence interval = 1.2-3.1). CONCLUSION: Physical inactivity in early pregnancy is associated with a higher risk of gestational diabetes mellitus among low-income women.

Estimation of the Costs of Invasive Cervical Cancer Treatment in Brazil: A Micro-Costing Study.

OBJECTIVE: The main objective of the present study was to estimate the annual treatment costs of invasive cervical cancer (ICC) per patient at an oncology center in Brazil from a societal perspective by considering direct medical, direct nonmedical, and indirect costs. METHODS: A cost analysis descriptive study, in which direct medical, direct nonmedical, and indirect costs were collected using a microcosting approach, was conducted between May 2014 and July 2016 from a societal perspective. The study population consisted of women diagnosed with ICC admitted to a tertiary hospital in Recife, state of Pernambuco, Brazil. The annual cost per patient was estimated in terms of the value of American Dollars (US$) in 2016. RESULTS: From a societal perspective, the annual ICC treatment cost per patient was US$ 2,219.73. Direct medical costs were responsible for 81.2% of the total value, of which radiotherapy and outpatient chemotherapy had the largest share. Under the base-case assumption, the estimated cost to the national budget of a year of ICC treatment in the Brazilian population was US$ 25,954,195.04. CONCLUSION: We found a high economic impact of health care systems treating ICC in a poor region of Brazil. These estimates could be applicable to further evaluations of the cost-effectiveness of preventing and treating ICC.

OBJETIVO: O objetivo principal do presente estudo foi estimar os custos anuais por paciente do tratamento do câncer do colo do útero (CCU) invasivo em um centro de oncologia no Brasil, sob a perspectiva da sociedade, considerando os custos diretos médicos, diretos não médicos e indiretos. MéTODOS: Foi realizado um estudo descritivo de análise de custos, no qual os custos médicos diretos, não médicos diretos e indiretos foram coletados por meio de uma abordagem de microcustos, realizado entre maio de 2014 e julho de 2016 sob a perspectiva da sociedade. A população do estudo foi composta por mulheres diagnosticadas com CCU invasivo internadas em um hospital terciário em Recife, PE, Brasil. O custo anual por paciente foi estimado em termos de dólares americanos (US$) para o ano de 2016. RESULTADOS: O custo anual do tratamento do CCU invasivo sob a perspectiva da sociedade foi de US$ 2.219,73 por paciente. Os custos médicos diretos foram responsáveis por 81,2% do valor total, dos quais a radioterapia e a quimioterapia ambulatorial tiveram a maior participação. Sob o pressuposto do caso base, o custo estimado para o orçamento nacional de um ano de tratamento do CCU invasivo na população brasileira foi de US$ 25.954.195,04. CONCLUSãO: Foi encontrado um alto impacto econômico dos sistemas de saúde para o tratamento do CCU invasivo em uma região pobre do Brasil. Essas estimativas poderão ser aplicáveis em avaliações adicionais do custo-efetividade da prevenção e tratamento do CCU.

Factors associated with diarrhea in children under five years old in the state of Pernambuco, according to surveys conducted in 1997 and 2006.

OBJECTIVE Describe and compare variations of the factors associated with the prevalence of diarrhea in children under five years old in the state of Pernambuco. METHODS We used the databases of two population-based surveys from the years 1997 and 2006, with 2,078 and 1,650 children, respectively, evaluated in 18 municipalities of Pernambuco (Metropolitan Region of Recife, urban and rural interior). The variables, allocated at hierarchical levels, were analyzed using prevalence and Poisson regression ratios. RESULTS Only four variables were independently associated and were included in the final hierarchical model: geographical area, number of people per room, maternal age and the age of the child. In 1997: urban interior = 1.33 (95%CI 1.06-1.66), rural interior = 1.22 (95%CI 0.97-1.53) and in 2006: urban interior = 1.87 (95%CI 1.31-2.66), rural interior = 2.07 (95%CI 1.50-2.85); number of persons per room (1997): 1 to less than 2 = 1.29 (95%CI 0.98-1.68), two or more = 1.47 (95%CI 1.11-1.95) and in 2006: 1 to less than 2 = 0.86 (95%CI 0.68-1.09), two or more = 1.29 (95%CI 0.94-1.75); maternal age (1997): 10 to 19 years = 1.48 (95%CI 1.05-2.08), 20 to 24 years = 1.23 (95%CI 0.94-1.60), 25 to 34 years = 1.01 (95%CI 0.78-1.30) and in 2006: 10 to 19 years old = 1.70 (95%CI 1.08-2.66), 20 to 24 years old = 1.64 (95%CI 1.16-2.32), 25 to 34 years = 1.20 (95%CI 0.89-1.62); and age of the child (1997): 0-11 months = 1.57 (95%CI 1.27-1.94), 12-23 months = 1.73 (95%CI 1.41-2.12) and in 2006: 0-11 months = 1.04 (95%CI 0.76-1.41), 12-23 months = 1.77 (95%CI 1.41-2.23). CONCLUSIONS There was a great variability of the conditioners of diarrhea in children between the two periods analyzed. At the public policy level, despite changes in terms of people, time sequences, and geographic spaces, diarrhea remains on an important scale in the ranking of government power.

Diarrheal diseases and hospitalization of children under five years of age according to population-based surveys in the State of Pernambuco, Brazil, in the years 1997 and 2006. / Doenças diarreicas e hospitalizações em menores de cinco anos no estado de Pernambuco, Brasil, nos anos de 1997 e 2006.

The scope of this paper was to assess the temporal and geographical trends of diarrhea and its implications on the demands of hospitalizations of children under five years of age in the state of Pernambuco in 1997 and 2006. Databases of two population-based surveys were assessed with probabilistic samples of 2078 children (1997) and 1650 children (2006) evaluated in 18 municipalities of Pernambuco, including the Metropolitan Region of Recife, Urban Interior and Rural Interior. Prevalence was considered to involve the occurrence of cases on the day or in the two weeks prior to the interview and as admissions, service cases with minimal hospital stay of 24 hours in the period, covering up to one year before the interview. The prevalence of diarrhea in Pernambuco had a statistically non-significant decline (19.8% to 18.1%; p = 0.192). However, a statistically-significant reduction was observed (16.9% to 10.5%; p = 0.003) in the Metropolitan Region of Recife. The number of admissions increased by more than double (2.7% to 5.5% in the State and from 1.6% to 3.8% within the Metropolitan Region of Recife), in contrast with national trends. Therefore, diarrhea in the State appears as the main component of the demands of pediatric hospitalizations during the period under scrutiny.

O objetivo deste estudo foi avaliar as tendências temporais e geográficas das diarreias e suas implicações nas demandas de hospitalizações de crianças menores de cinco anos no Estado de Pernambuco, nos anos 1997 e 2006. Foram usados os bancos de dados de dois inquéritos de base populacional, com amostras probabilísticas de 2078 crianças, em 1997, e 1650 crianças, em 2006, avaliadas em 18 municípios de Pernambuco, incluindo a Região Metropolitana do Recife, Interior Urbano e Interior Rural. Considerou-se como prevalência a ocorrência de casos no dia ou nas duas semanas anteriores à entrevista e como internações o atendimento de casos com internação mínima de 24 horas, cobrindo o retrospecto de 12 meses. A prevalência das diarreias em Pernambuco teve um declínio estatisticamente não significante (19,8% para 18,1%; p = 0,192); contudo, na Região Metropolitana do Recife, foi observada uma redução estatisticamente significante (16,9% para 10,5%; p = 0,003). As internações aumentaram em mais de duas vezes (2,7% para 5,5%, no estado, e de 1,6% para 3,8%, na RMR), contrapondo-se, assim, às tendências nacionais. Portanto, as diarreias no Estado passaram a figurar como o principal componente das demandas de hospitalizações pediátricas no período analisado.

Factors associated with diarrhea in children under five years old in the state of Pernambuco, according to surveys conducted in 1997 and 2006 / Fatores associados à diarreia em menores de cinco anos, no estado de Pernambuco, segundo inquéritos realizados em 1997 e 2006

ABSTRACT OBJECTIVE Describe and compare variations of the factors associated with the prevalence of diarrhea in children under five years old in the state of Pernambuco. METHODS We used the databases of two population-based surveys from the years 1997 and 2006, with 2,078 and 1,650 children, respectively, evaluated in 18 municipalities of Pernambuco (Metropolitan Region of Recife, urban and rural interior). The variables, allocated at hierarchical levels, were analyzed using prevalence and Poisson regression ratios. RESULTS Only four variables were independently associated and were included in the final hierarchical model: geographical area, number of people per room, maternal age and the age of the child. In 1997: urban interior = 1.33 (95%CI 1.06-1.66), rural interior = 1.22 (95%CI 0.97-1.53) and in 2006: urban interior = 1.87 (95%CI 1.31-2.66), rural interior = 2.07 (95%CI 1.50-2.85); number of persons per room (1997): 1 to less than 2 = 1.29 (95%CI 0.98-1.68), two or more = 1.47 (95%CI 1.11-1.95) and in 2006: 1 to less than 2 = 0.86 (95%CI 0.68-1.09), two or more = 1.29 (95%CI 0.94-1.75); maternal age (1997): 10 to 19 years = 1.48 (95%CI 1.05-2.08), 20 to 24 years = 1.23 (95%CI 0.94-1.60), 25 to 34 years = 1.01 (95%CI 0.78-1.30) and in 2006: 10 to 19 years old = 1.70 (95%CI 1.08-2.66), 20 to 24 years old = 1.64 (95%CI 1.16-2.32), 25 to 34 years = 1.20 (95%CI 0.89-1.62); and age of the child (1997): 0-11 months = 1.57 (95%CI 1.27-1.94), 12-23 months = 1.73 (95%CI 1.41-2.12) and in 2006: 0-11 months = 1.04 (95%CI 0.76-1.41), 12-23 months = 1.77 (95%CI 1.41-2.23). CONCLUSIONS There was a great variability of the conditioners of diarrhea in children between the two periods analyzed. At the public policy level, despite changes in terms of people, time sequences, and geographic spaces, diarrhea remains on an important scale in the ranking of government power.

RESUMO OBJETIVO Descrever e comparar variações dos fatores associados à prevalência de diarreia em menores de cinco anos no estado de Pernambuco. MÉTODOS Foram utilizados os bancos de dados de dois inquéritos de base populacional nos anos de 1997 e 2006, com 2.078 e 1.650 crianças, respectivamente, avaliadas em 18 municípios de Pernambuco (Região Metropolitana do Recife, interior urbano e rural). As variáveis, alocadas em níveis hierárquicos, foram analisadas por meio de razões de prevalência e regressão de Poisson. RESULTADOS Apenas quatro variáveis se mostraram independentemente associadas e constaram no modelo final hierarquizado: área geográfica, número de pessoas por cômodo, idade materna e idade da criança. Em 1997: interior urbano = 1,33 (IC95% 1,06-1,66), interior rural = 1,22 (IC95% 0,97-1,53) e em 2006: interior urbano = 1,87 (IC95% 1,31-2,66), interior rural = 2.07 (IC95% 1.50-2.85); número de pessoas por cômodo (1997): 1 a menos de 2 = 1,29 (IC95% 0,98-1,68), dois ou mais = 1,47 (IC95% 1,11-1,95) e em 2006: 1 a menos de 2 = 0.86 (IC95% 0,68-1,09), dois ou mais = 1,29 (IC95% 0,94-1,75); idade materna (1997): 10 a 19 anos = 1,48 (IC95% 1,05-2,08), 20 a 24 anos = 1,23 (IC95% 0,94-1,60), 25 a 34 anos = 1,01 (IC95% 0,78-1,30) e em 2006: 10 a 19 anos = 1,70 (IC95% 1,08-2,66), 20 a 24 anos = 1,64 (IC95% 1,16-2,32), 25 a 34 anos = 1,20 (IC95% 0,89-1,62); e idade da criança (1997): 0-11 meses = 1,57 (IC95% 1,27-1,94), 12-23 meses = 1,73 (IC95% 1,41-2,12) e em 2006: 0-11 meses = 1,04 (IC95% 0,76-1,41), 12-23 meses = 1,77 (IC95% 1,41-2,23). CONCLUSÕES Houve uma grande variabilidade dos condicionantes das diarreias em crianças entre os dois períodos analisados. Em nível de políticas públicas, apesar de mudanças em termos de pessoas, sequências temporais e espaços geográficos, as diarreias continuam em uma escala importante no elenco de prioridades do poder governamental.
