Dengue fever, chikungunya fever, and zika virus infections are increasing public health problems in the world, the last two diseases having recently emerged in Brazil. This ecological study employed spatial analysis of probable cases of dengue fever, chikungunya fever, and zika virus infections reported to the National Mandatory Reporting System (SINAN) in Maranhao State from 2015 to 2016. The software GeoDa version 1.10 was used for calculating global and local Moran indices. The global Moran index identified a significant autocorrelation of incidence rates of dengue (I=0.10; p=0.009) and zika (I=0.07; p=0.03). The study found a positive spatial correlation between dengue and the population density (I=0.31; p<0.001) and a negative correlation with the Performance Index of Unified Health System (PIUHS) by basic care coverage (I=-0.08; p=0.01). Regarding chikungunya fever, there were positive spatial correlations with the population density (I=0.06; p=0.03) and the Municipal Human Development Index (MHDI) (I=0.10; p=0.002), and a negative correlation with the Gini index (I=-0.01; p<0.001) and the PIUHS by basic care coverage (I=-0.18; p<0.001). Lastly, we found positive spatial correlations between Zika virus infections and the population density (I=0.13; p=0.005) and the MHDI (I=0.12; p<0.001), as well as a negative correlation with the Gini index (I=-0.11; p<0.001) and the PIUHS by basic care coverage (I=-0.05; p=0.03). Our results suggest that several socio-demographic factors influenced the occurrence of dengue fever, chikungunya fever, and zika virus infections in Maranhao State.

“…Although Brazil has shown significant improvements in women's and children's health on a national scale, not all regions and states showed the same trend or evolved at the same pace 195 . Regional inequalities were reported in several studies included in the review, primarily through spatial analyses 124,134,138,[148][149][150]165,166 . While declining for many indicators, evidence of persistent inequali- ties between regions of the country was found in the temporal analysis of the health conditions of women and children 195 .…”

“…These are the sources used in practically all the studies grouped in the thematic line 'mortality' (n = 13). This group includes publications that have evaluated time trends 146,147 and spatial distribution [148][149][150] of mortality indicators, their determinants 151 , and risk factors 152,153 . The authors also explored inequalities 154 and death avoidability 155 , including analysis according to ethnicity/skin color 156 and the impact of economic crises on mortality 157 .…”

Resumo Revisamos a produção sobre saúde materna e de crianças menores de dez anos disseminada pela Revista Ciência & Saúde Coletiva, através de revisão sistemática de publicações dos últimos 25 anos, com foco em estudos quantitativos. Características de autores e populações sob estudo, eixos temáticos e metodologia são descritos. Foram selecionadas 170 publicações classificadas em 12 temas. Gestação, parto ou puerpério foram objeto de 47 estudos, seguidos de avaliação antropométrica (29 artigos), amamentação (24) e mortalidade (13). Os trabalhos selecionados representaram 3,5% do total de artigos originais publicados pela Revista desde 1996, com tendência crescente, constituindo cerca de 5% das publicações em 2015-2020. As principais fontes de dados foram registros de serviços de saúde, sistemas de informação e inquéritos populacionais. O delineamento transversal foi utilizado em 113 dos 170 artigos e 70% destes abrangeram apenas um município. As Regiões Sudeste e Nordeste foram alvo da maioria dos estudos, sendo a Região Norte a menos representada. As publicações refletem a complexidade de temas que perpassam a saúde materna e da criança, com especial foco na importância do Sistema Único de Saúde e demonstrando como dados em acesso aberto podem contribuir para a pesquisa em Saúde Coletiva.

“…The analysis of spatial data of the infant deaths investigated allowed the identification of a heterogeneous pattern of occurrence of mortality in children under one year old, with a higher concentration of cases in 12 out of 94 neighborhood sin Recife, with similar spatial clusters for neonatal and post-neonatal deaths. The detection of these areas reveals particularities in the distribution of deaths that may reflect inequalities in health and social conditions (Rodrigues et al, 2014;Nucci, Souccar, & Castilho, 2016;Faria, 2016;Leal, Bittencourt, Torres, Niquini, & Souza Jr, 2017) and indicates locations with greater need for investment in public policies directed at the health of women and children.…”

“…The punctual analysis of deaths by characterizing the territory in detail reveals areas with a higher concentration of deaths and indicates the presence of risk factors in certain localities (MacQuillan et al, 2017). Studies on the spatial analysis of infant mortality point to the usefulness of these approaches for the elaboration and development of policies aimed at coping with the determinants of these deaths, particularly those related to healthcare (Rodrigues et al, 2014;Faria, 2016;Rodrigues et al, 2016;Venâncio, Tuan, Vaz, & Nascimento, 2016;Leal et al, 2017). Likewise, the characterization of the epidemiological profile of infant deaths is recognized as an important tool for drawing strategies to deal with the problem, in particular, by investigating the events, because it allows a better understanding of the circumstances of their occurrence (Vanderlei & Navarrete, 2013).…”

To describe the occurrence and spatial distribution of infant deaths investigated by surveillance in Recife, state of Pernambuco, Brazil, in 2014. This is an exploratory ecological study investigating 183 infant deaths. Data from the confidential records of surveillance investigation of the infant death and the Mortality Information System were used. In order to detect spatial distribution patterns, the kernel estimation of infant, neonatal and post-neonatal mortality was used. Deaths were mainly of the neonatal type (n = 144; 78.69%), with gestational age below 37 weeks (n = 147; 80.3%) and birth weight lower than 2500 g (n = 143; 78.1%). The main causes of infant deaths were the disorders originating in the perinatal period, with emphasis on maternal hypertensive disorders (n = 31; 16.9%). The kernel map showed a higher density in 12 neighborhoods of the North (4), Northwest (2), West (3) and South (3) regions of the municipality. It was found a heterogeneous pattern in the occurrence and distribution of deaths in the territory; spatial clusters were observed in several areas of Recife with similar geographic spaces between types of death.
