This study aimed to analyse hospitalisations for respiratory diseases in the Western Region of Bahia, Northeast Brazil, from 2010 to 2019, and to explore possible correlations with meteorological data.
This descriptive, epidemiological, ecological study analysed data from 37 municipalities in the Western Bahia health macro-region, defined according to geographical, administrative, demographic, epidemiological, social and cultural criteria, and accounting for availability of health resources.
Hospitalisation data for respiratory diseases, including total admissions and disease frequency, mean and prevalence, were obtained from DATASUS (Ministry of Health). The data were evaluated by sex, age group and city. Statistical tests, such as the Chi-squared test and analysis of variance, were used for data analysis. Meteorological data were compared using the t-test and Mann-Whitney test. Correlations between health indicators and weather data were assessed using the Pearson and Spearman correlation coefficients.
Over the investigated period, there were 536,195 hospitalisation records in the region, with respiratory diseases accounting for 17.1% of admissions. Notably, 40% of respiratory hospitalisations were among children aged 0-9 years. The most prevalent respiratory conditions were pneumonia and asthma, which together constituted 73% of all respiratory hospitalisations. A significant negative correlation was observed between respiratory diseases and rainfall (r = -0.70, P = 0.011).
Pneumonia and asthma remain important causes of hospitalisation among children in the Western Bahia Region. The study findings suggest that respiratory diseases are influenced by rainfall, possibly due to increased atmospheric pollutants during time of low rainfall. These findings emphasise the importance of environmental factors in the development and exacerbation of respiratory diseases.
本研究旨在分析 2010 年至 2019 年巴西东北部巴伊亚西部地区因呼吸疾病住院的情况，并探讨与气象数据的可能相关性。
这是一项描述性、流行病学、生态学研究，分析了巴伊亚西部地区卫生大区 37 个城市的数据，这些城市是根据地理、行政、人口、流行病学、社会和文化标准定义的，并考虑了卫生资源的可用性。
从 DATASUS（卫生部）获得呼吸疾病住院数据，包括总入院人数和疾病频率、平均值和患病率，按性别、年龄组和城市进行评估。使用卡方检验和方差分析等统计检验方法进行数据分析。使用 t 检验和曼-惠特尼检验比较气象数据。使用 Pearson 和 Spearman 相关系数评估健康指标与天气数据之间的相关性。
在所研究的期间内，该地区有 536195 例住院记录，其中呼吸疾病占入院人数的 17.1%。值得注意的是，40%的呼吸住院患者为 0-9 岁的儿童。最常见的呼吸疾病是肺炎和哮喘，两者合计占所有呼吸住院患者的 73%。呼吸疾病与降雨量呈显著负相关（r=-0.70，P=0.011）。
肺炎和哮喘仍然是巴伊亚西部地区儿童住院的重要原因。研究结果表明，呼吸疾病受降雨量的影响，可能是由于降雨量低时大气污染物增加所致。这些发现强调了环境因素在呼吸疾病的发展和恶化中的重要性。
