Epidemiological investigations regarding temperature influence on human health have focused on mortality rather than morbidity. In addition, most information comes from developed countries despite the increasing evidence that climate change will have devastating impacts on disadvantaged populations living in developing countries. In the present study, we assessed the impact of daily temperature range on upper and lower respiratory infections in Cordoba, Argentina, and explored the effect modification of socio-economic factors and influence of airborne particles We found that temperature range is a strong risk factor for admissions due to both upper and lower respiratory infections, particularly in elderly individuals, and that these effects are more pronounced in sub-populations with low education level or in poor living conditions. These results indicate that socio-economic factors are strong modifiers of the association between temperature variability and respiratory morbidity, thus they should be considered in risk assessments.
关于温度对人类健康影响的流行病学调查主要集中在死亡率而非发病率上。此外，尽管越来越多的证据表明气候变化将对生活在发展中国家的弱势群体产生毁灭性影响，但大多数信息仍来自发达国家。在本研究中，我们评估了日温度范围对阿根廷科尔多瓦上呼吸道和下呼吸道感染的影响，并探讨了社会经济因素的效应修正以及空气颗粒物的影响。我们发现，温度范围是上呼吸道和下呼吸道感染入院的一个强有力的风险因素，尤其是在老年人中，而且这些影响在教育水平低或生活条件差的亚人群中更为明显。这些结果表明，社会经济因素是温度变异性与呼吸道发病率之间关联的强有力的效应修正因素，因此在风险评估中应予以考虑。
