Health impact assessment (HIA) has been widely recommended for future social policies and investment, such as housing improvement. However, concerns have been raised about the utility and predictive value of an HIA. Use of existing research data would add more weight to forecasts by an HIA. METHODS, RESULTS, and
A recent systematic review of housing intervention studies found a lack of research. The authors recommended that a broader evidence base would be needed to support HIA. In response to consultation with policymakers and HIA practitioners this paper presents a way in which research can be used to inform HIA. Based on the systematic review, the authors have developed a table of synthesised findings indicating the expected health effects of specific housing improvements. The authors also reviewed observational data of housing associated health risks to highlight the key impacts to consider when doing a housing HIA. The findings are presented and the authors discuss how they should be used to inform evidence based housing HIA. In addition to considering the existing research, HIA must consider the local relevance of research. Consultation with local stakeholders also needs to be incorporated to the final assessment. The lack of data and the difficulties in gathering and reviewing data mean that not all HIAs will be able to be informed by research evidence. Well conducted prospective validation of HIAs would contribute to the development of healthy housing investment by informing future housing HIA.
健康影响评估（HIA）已被广泛推荐用于未来的社会政策和投资，如住房改善。然而，人们对HIA的效用和预测价值提出了担忧。使用现有研究数据将增加HIA预测的可信度。
方法、结果与结论：最近一项对住房干预研究的系统评价发现研究不足。作者建议需要更广泛的证据基础来支持HIA。为回应与政策制定者和HIA从业者的磋商，本文提出了一种利用研究为HIA提供信息的方法。基于该系统评价，作者编制了一份综合研究结果表，表明特定住房改善措施预期的健康影响。作者还审查了与住房相关的健康风险的观察数据，以突出进行住房HIA时应考虑的关键影响。本文展示了研究结果，并讨论了应如何利用这些结果为基于证据的住房HIA提供信息。除了考虑现有研究外，HIA还必须考虑研究与当地的相关性。与当地利益相关者的磋商也需要纳入最终评估。数据的缺乏以及收集和审查数据的困难意味着并非所有HIA都能获得研究证据的支持。对HIA进行良好的前瞻性验证，将通过为未来的住房HIA提供信息，促进健康住房投资的发展。
