识别关于全年中风发病率变化和大气温度的特定地区模式可能对中风护理的组织有用，特别是在低资源环境中。我们的目的是描述在莫桑比克马普托，中风住院的发病率在不同季节和短期温度变化的变化。在2005年8月1日至2006年7月31日期间，我们根据世界卫生组织的STEPwise方法在马普托居民中确定了651例中风事件。症状发作日定义为索引日期。我们用Poisson回归计算了粗发病率和调整后（湿度、降水量和温度）发病率比（IRR）和95%置信区间（CI）。中风发病率随季节（干与湿：粗IRR 5.98，95% CI：0.84 -1.15）、索引日期的气温或前2周的平均气温变化不显著。如果在过去10天内，任何连续2天之间的最低温度下降大于或等于3°C，则中风的发病率约高出30%（最低温度变化为−5.1至−3.0 vs −2.3至−.4，校正后的IRR = 1.31，95%CI：1.09-1.57）。根据最高温度的变化，没有观察到显着的关联。最低气温的突然下降与马普托中风住院率的上升有关。这提供了重要的信息，预测的时期，更高的医院富裕，因为中风，并了解潜在的触发中风事件的机制。
Identifying locale-specific patterns regarding the variation in stroke incidence throughout the year and with atmospheric temperature may be useful to the organization of stroke care, especially in low-resource settings. We aimed to describe the variation in the incidence of stroke hospitalizations across seasons and with short-term temperature variation, in Maputo, Mozambique. Between August 1, 2005, and July 31, 2006, we identified 651 stroke events in Maputo dwellers, according to the World Health Organization's STEPwise approach. The day of symptom onset was defined as the index date. We computed crude and adjusted (humidity, precipitation and temperature) incidence rate ratios (IRRs) and 95% confidence intervals (CIs) with Poisson regression. Stroke incidence did not vary significantly with season (dry versus wet: crude IRR 5 .98, 95% CI: .84-1.15), atmospheric temperature at the index date, or average atmospheric temperature in the preceding 2 weeks. The incidence rates of stroke were approximately 30% higher when in the previous 10 days there was a decline in the minimum temperature greater than or equal to 3°C between any 2 consecutive days (variation in minimum temperature −5.1 to −3.0 versus −2.3 to −.4, adjusted IRR = 1.31, 95% CI: 1.09-1.57). No significant associations were observed according to the variation in maximum temperatures. Sudden declines in the minimum temperatures were associated with a higher incidence of stroke hospitalizations in Maputo. This provides important information for prediction of periods of higher hospital affluence because of stroke and to understand the mechanisms underlying the triggering of a stroke event.
