气候模型预测，热浪的频率和严重程度将增加。尽管有许多关于热浪死亡率的研究，但很少有研究调查发病率。在这项研究中，我们调查了在2006年加州热浪期间，任何年龄或种族/民族组的住院和急诊（艾德）就诊率是否总体上或因选定疾病而增加。我们汇总了加州六个地理区域的县级住院和艾德就诊的所有原因和10个原因组。我们计算了热浪期间（2006年7月15日至8月1日）的超额发病率和比率（RR），并将这些数据与参考期（2006年7月8日至14日和8月12日至22日）的数据进行了比较。在热浪期间，全州发生了16,166次额外的艾德就诊和1,182次额外的住院。全州因热相关原因就诊的艾德增加[RR = 6.30; 95%置信区间（CI），5.67-7.01]，特别是在包括旧金山弗朗西斯科在内的中央海岸地区。儿童（0-4岁）和老年人（≥ 65岁）的风险最大。艾德访视也显示急性肾衰竭、心血管疾病、糖尿病、电解质失衡和肾炎显著增加。我们观察到因发热相关疾病（RR = 10.15; 95%CI，7.79-13.43）、急性肾功能衰竭、电解质紊乱和肾炎住院的RR显著升高。2006年加州的热浪对发病率产生了重大影响，包括气温相对温和的地区。这表明，人口驯化和适应能力影响风险。通过更好地了解这些影响和人口脆弱性，当地社区可以改善热浪准备，以科普全球变暖的未来。
Climate models project that heat waves will increase in frequency and severity. Despite many studies of mortality from heat waves, few studies have examined morbidity. In this study we investigated whether any age or race/ethnicity groups experienced increased hospitalizations and emergency department (ED) visits overall or for selected illnesses during the 2006 California heat wave. We aggregated county-level hospitalizations and ED visits for all causes and for 10 cause groups into six geographic regions of California. We calculated excess morbidity and rate ratios (RRs) during the heat wave (15 July to 1 August 2006) and compared these data with those of a reference period (8–14 July and 12–22 August 2006). During the heat wave, 16,166 excess ED visits and 1,182 excess hospitalizations occurred statewide. ED visits for heat-related causes increased across the state [RR = 6.30; 95% confidence interval (CI), 5.67–7.01], especially in the Central Coast region, which includes San Francisco. Children (0–4 years of age) and the elderly (≥ 65 years of age) were at greatest risk. ED visits also showed significant increases for acute renal failure, cardiovascular diseases, diabetes, electrolyte imbalance, and nephritis. We observed significantly elevated RRs for hospitalizations for heat-related illnesses (RR = 10.15; 95% CI, 7.79–13.43), acute renal failure, electrolyte imbalance, and nephritis. The 2006 California heat wave had a substantial effect on morbidity, including regions with relatively modest temperatures. This suggests that population acclimatization and adaptive capacity influenced risk. By better understanding these impacts and population vulnerabilities, local communities can improve heat wave preparedness to cope with a globally warming future.
