The present prospective study was conducted at two urban slums of Delhi, Kusumpur Pahari and Kathputly Colony, in the peak winter season from November 1994 through February 1995. We studied 642 infants to determine the incidence of acute lower respiratory infection (ALRI) and its relationship to indoor air pollution due to fuel used for cooking (wood or kerosene). In Kusumpur Pahari, there were 317 children (142 wood and 175 kerosene), including 64 controls and 78 cases of ALRI in the wood fuel group and 81 controls and 94 ALRI cases in the kerosene group (p > 0.05). Out of 316 children in Kathputly Colony (174 wood and 142 kerosene), there were 33 and 45 ALRI cases in the wood and kerosene groups, respectively (p < 0.05). Controls were children without ALRI and were used as controls in different groups. The demographic data and risk factors, namely, nutritional and immunization status, were comparable in ALRI cases and controls in both study areas. Pneumonia was the most common ailment in all the groups. Bronchiolitis was reported in 22.5% of the wood group and 27.1% of the kerosene group in Kathputly Colony versus 13.7% in the wood group and 12.1% in the kerosene group in Kusumpur Colony. Only one case of croup was reported from Kusumpur Pahari among wood users. The duration of illness was longer in the Kusumpur Pahari due to poor compliance, feeding, and child rearing habits. In conclusion, a higher incidence of ALRI was reported in kerosene users in Kathputly Colony, a high pollution area; however, the reasons for the differences observed need further elucidation.
本前瞻性研究于1994年11月至1995年2月冬季高峰期间，在德里的两个城市贫民窟库萨姆布尔·帕哈里和卡特普特利殖民地进行。我们研究了642名婴儿，以确定急性下呼吸道感染（ALRI）的发病率及其与烹饪所用燃料（木材或煤油）导致的室内空气污染的关系。在库萨姆布尔·帕哈里，有317名儿童（142名使用木材和175名使用煤油），其中木材燃料组有64名对照和78例ALRI病例，煤油组有81名对照和94例ALRI病例（p>0.05）。在卡特普特利殖民地的316名儿童（174名使用木材和142名使用煤油）中，木材组和煤油组分别有33例和45例ALRI病例（p<0.05）。对照组为无ALRI的儿童，并在不同组中用作对照。两个研究区域的ALRI病例和对照组的人口统计学数据以及危险因素，即营养和免疫状况，具有可比性。肺炎是所有组中最常见的疾病。在卡特普特利殖民地，木材组有22.5%的儿童报告患有细支气管炎，煤油组有27.1%，而在库萨姆布尔殖民地，木材组为13.7%且煤油组为12.1%。在库萨姆布尔·帕哈里，木材使用者中仅报告了1例哮吼病例。由于依从性差、喂养和育儿习惯，库萨姆布尔·帕哈里的疾病持续时间更长。总之，在高污染地区卡特普特利殖民地，煤油使用者中报告的ALRI发病率较高；然而，观察到的差异原因需要进一步阐明。
