家庭空气污染（HAP）每年导致全球350万至400万人死亡。最近的干预措施，使用改进的炉灶（ICS），以减少HAP已纳入温度传感器作为炉灶使用监测器（SUMs），以评估炉灶的使用。我们部署在45个肯尼亚农村家庭的6 ICSs的有效性研究SUMs。连续安装炉灶2周，并在每2周期间进行48小时的厨房空气监测。我们在ICS和传统炉灶（TCS）上放置了SUM，并使用算法分析了连续温度数据，以检查烹饪事件的数量，ICS的独家使用天数以及炉灶使用模式如何影响HAP。堆叠（定义为在同一天同时使用TCS和ICS）发生在40%的研究日，仅使用ICS发生在25%的研究日。当研究人员不在场时，ICS的使用下降，这可能对这些社区的长期炉灶采用产生影响。持续使用TCS也与较高的HAP水平相关。SUM是表征炉灶使用的有价值的工具，并提供额外的信息来解释ICS干预研究期间测量的HAP水平。
Household air pollution (HAP) contributes to 3.5–4 million annual deaths globally. Recent interventions using improved cookstoves (ICS) to reduce HAP have incorporated temperature sensors as stove use monitors (SUMs) to assess stove use. We deployed SUMs in an effectiveness study of 6 ICSs in 45 Kenyan rural homes. Stove were installed sequentially for 2 weeks and kitchen air monitoring was conducted for 48 hours during each 2-week period. We placed SUMs on the ICSs and traditional cookstoves (TCS) and the continuous temperature data were analyzed using an algorithm to examine the number of cooking events, days of exclusive use of ICS, and how stove use patterns affect HAP. Stacking, defined as using both a TCS and an ICS in the same day, occurred on 40% of the study days, and exclusive use of the ICS occurred on 25% of study days. When researchers were not present, ICS use declined, which can have implications for long-term stove adoption in these communities. Continued use of TCSs was also associated with higher HAP levels. SUMs are a valuable tool for characterizing stove use and provide additional information to interpret HAP levels measured during ICS intervention studies.
