Abstract
To assess the short term health effects of improving housing. Randomised to waiting list. 119 council owned houses in south Devon, UK. About 480 residents of these houses. Upgrading houses (including central heating, ventilation, rewiring, insulation, and re-roofing) in two phases a year apart. All residents completed an annual health questionnaire: SF36 and GHQ12 (adults). Residents reporting respiratory illness or arthritis were interviewed using condition-specific questionnaires, the former also completing peak flow and symptom diaries (children) or spirometry (adults). Data on health service use and time lost from school were collected. Interventions improved energy efficiency. For those living in intervention houses, non-asthma-related chest problems (Mann-Whitney test, p = 0.005) and the combined asthma symptom score for adults (Mann-Whitney test, z = 2.7, p = 0.007) diminished significantly compared with control houses. No difference between intervention and control houses was seen for SF36 or GHQ12. Rigorous study designs for the evaluation of complex public health and community based interventions are possible. Quantitatively measured health benefits are small, but as health benefits were measured over a short time scale, there may have been insufficient time for measurable improvements in general and disease-specific health to become apparent.Keywords
