ResumoObjetivo: Analisar a sazonalidade climática dos atendimentos ambulatoriais por doença respiratória (DR) em menores de 15 anos. Resultados: Indivíduos do sexo masculino tiveram taxa quase 50% maior (37,3/25,0) de atendimentos ambulatoriais por doenças das vias aéreas inferiores que os do sexo feminino. As taxas de atendimentos ambulatoriais por DR em menores de 15 anos apresentaram variação com o aumento da idade, passando de 457,7‰ nos menores de 1 ano de idade para 133,5‰ no grupo de 10 a 14 anos. Os atendimentos por DR foram em média 21% menos freqüentes(4.148/5.231) no período seco (p = 0,000). Observou-se picos de atendimento nos meses de março e agosto, mais acentuados em março, período chuvoso na região. Métodos Conclusão:Os atendimentos ambulatoriais por DR, especialmente por doenças das vias aéreas superiores, estão relacionados ao período chuvoso no município.J Pediatr (Rio J). 2008;84(6) AbstractObjective: To analyze the climatic seasonality of primary care visits for respiratory disease (RD) in children less than 15 years old.Methods: This was a descriptive, epidemiological study based on data from the municipal records of primary care events from basic healthcare centers for the period 2004-2005, for the municipality of Tangará da Serra (MT), Brazil. Population estimates were obtained from the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística, IGBE), and data on temperature and relative humidity of the air, from the National Meteorology Institute (Instituto Nacional de Meteorologia, INMET). Mean rates of primary care visits for RD were calculated according to sex, age group and anatomic location of complaint. The ratio of dry season to rainy season visits was calculated according to anatomic location of the RD. Data were analyzed using Epi-Info 3.2, testing differences between proportions using the chi-square test to a significance level of 5%. Results:Male children had an almost 50% greater (37.3/25.0) rate of primary care visits for diseases of the lower respiratory tract than did females. The rates of primary care visits due to RD in children under 15 years of age varied as age increased, varying from 457.7‰ of children less than 1 year of age to 133.5‰ in the 10 to 14 years-of-age group. During the dry season there were an average of 21% (4,148/5,231) fewer visits for RD (p = 0.000). Peaks in numbers of visits were observed during the months of March and August, being more accentuated in March, which is the wet season in the region. Conclusion:Primary care visits for RD, especially those due to upper airway diseases, are related to the rainy season in this municipality.J Pediatr (Rio J). 2008;84(6):543-549: Respiratory diseases, climatic seasonality, upper airway diseases, lower respiratory tract diseases climate, season.

“…Alguns estudos mostram uma relação sazonal nas hospitalizações por asma e nos atendimentos ambulatoriais pela mesma causa em várias regiões do Brasil 13,14 . No que se refere à Amazônia brasileira, vários estudos apontam a importância da associação entre a sazonalidade climática e a ocorrência de doenças respiratórias, com predominância no período de seca 15,16 .…”

Objective: To analyze the distribution of hospitalizations of children for asthma in the states comprising the Brazilian Amazon, as well as the variations of hospitalization according to climatic seasonality. Methods:A descriptive study of the distribution of hospitalizations for asthma of individuals aged 0 to 14 years living in the Brazilian Amazon, according to trend, spatial distribution, and climatic seasonality over the period from 2001 to 2007. We used the database of authorizations for hospitalizations (AIH) of the Hospital Information System (SIH/SUS) of the Brazilian Ministry of Health. Results:The spatial distribution of hospitalizations for asthma resembles the configuration of the "arc of deforestation," mainly in the states of Rondônia and Maranhão. The distribution of annual hospitalizations for asthma decreased from 8.1 to 2.6 hospitalizations/1,000 inhabitants during the period. There was a peak of hospitalizations in March and May in all states. The seasonal differences were on average 10%, with the highest rates during the rainy season. Conclusion:We concluded that hospitalizations for asthma are more frequent in the months of more intense rainfall, with greater magnitude in the states comprising the "arc of deforestation" in the Brazilian Amazon, especially Rondônia and Maranhão.J Pediatr (Rio J). 2009;85(6):541-546: Asthma, Amazon, hospitalization, children, spatial distribution. ResumoObjetivo: Analisar a distribuição das internações hospitalares por asma em crianças nos estados que compõem a Amazônia brasileira e as variações das internações segundo a sazonalidade climática. Resultados: A distribuição espacial das hospitalizações por asma assemelha-se à configuração do arco do desmatamento, com destaque para os estados de Maranhão e Rondônia. As hospitalizações anuais por asma decresceram de 8,1 para 2,6 internações por mil habitantes no decorrer do período estudado. Verifica-se um pico de internações nos meses de março e maio em todos os estados. As diferenças sazonais alcançaram em média 10% do conjunto das unidades da federação, com as maiores taxas no período chuvoso. Métodos Conclusão:Conclui-se que as hospitalizações por asma em crianças são mais frequentes nos meses chuvosos, com maior magnitude nos estados que compõem o arco do desmatamento da Amazônia brasileira, especialmente Rondônia e Maranhão.

“…12 Some studies have demonstrated a seasonal relation in terms of hospitalizations and outpatient medical visits for asthma in several regions of Brazil. 13,14 With regard to the Brazilian Amazon, several studies have highlighted the importance of the association between climatic seasonality and occurrence of respiratory diseases, mainly in the drought season. 15,16 This region is characterized by well-established drought and rainy seasons.…”
