This study assessed associations between house characteristics and mold and musty odor, using data from three consecutive (2005, 2010, and 2015) New Zealand House Condition Surveys, involving a total of 1616 timber‐framed houses. Mold, musty odor, and house characteristics were assessed by independent building inspectors. We used multivariate logistic regression analyses mutually adjusted for other house characteristics for each survey separately. Positive and independent associations were found with tenure, ventilation, insulation, and envelope condition for both mold in living and bedrooms and musty odor. In particular, we found significant dose‐response associations with envelope condition, ventilation, and insulation. Odds of mold increased 2.4–15.9 times (across surveys) in houses with the worst building envelope condition (BEC; p < 0.05–0.001 for trend); optimal ventilation reduced the risk of mold by 60% and the risk of musty odor by 70%–90% (p < 0.01 for trend). Other factors associated with mold and musty odor included: tenure, with an approximate doubling of odds of mold across surveys; and insulation with consistent dose‐response patterns in all outcomes and surveys tested (p < 0.05 for trend in two surveys with mold and one survey for odor). In conclusion, this study showed the importance of BEC, ventilation, and insulation to avoiding harmful damp‐related exposures.

房屋特征和状况决定可见霉菌和霉味的决定因素：2005、2010和2015年三项新西兰房屋状况调查的结果

这项研究使用来自连续三个（2005年，2010年和2015年）新西兰房屋状况调查的数据评估了房屋特征与霉菌和霉味之间的关联性，涉及总共1616栋木结构房屋。霉菌，霉味和房屋特性由独立的建筑检查员进行评估。对于每个调查，我们分别使用针对其他房屋特征进行相互调整的多元逻辑回归分析。在起居室，卧室和霉菌的气味和霉味方面，与保有权，通风，隔热和围护条件之间存在积极和独立的联系。特别是，我们发现与包膜状况，通风和隔热有显着的剂量反应相关性。在建筑围护条件最差的房屋中，霉菌的发生率（整个调查）增加了2.4–15.9倍（BEC； 趋势p <0.05–0.001）；最佳通风可将发霉的风险降低60％，将发霉气味的风险降低70％-90％（ 趋势p <0.01）。与霉菌和霉味相关的其他因素包括：保有权，整个调查期间霉菌几率大约翻倍；在所有结果和测试中均采用一致的剂量反应模式进行隔热（ 两次霉菌调查和一项气味调查的趋势p <0.05）。总之，这项研究表明了BEC，通风和隔热对于避免有害的潮湿相关暴露的重要性。
