Higher energy efficient homes are associated with increased risk of doctor diagnosed asthma in a UK subpopulation.

摘要: Abstract Introduction The United Kingdom (UK) has one of the highest prevalence asthma in world, which represents a significant economic and societal burden. Reduced ventilation resulting from increased energy efficiency measures acts as modifier for mould contamination risk allergic diseases. To our knowledge no previous study combined detailed asset management property health data together to assess impact household (using UK Government's Standard Assessment Procedure) on outcomes an adult population residing social housing. Methods Postal questionnaires were sent 3867 housing properties collect demographic, environmental information all occupants. Detailed data, residency periods, indices multiple deprivation (IMD) ratings also investigated. Logistic regression was used calculate odds ratios confidence intervals while allowing clustering individuals coming same location. Results Eighteen percent target recruited into study. Adults had mean age 59 (SD ± 17.3) years there higher percentage female (59%) single occupancy (58%) respondents. Housing demographic characteristics representative homes. A unit increase Procedure (SAP) rating associated with 2% current asthma, greatest homes SAP > 71. We assessed exposure found that presence mouldy/musty odour two-fold (OR 2.2 95%; CI 1.3–3.8). led 4–5% reduction visible growth odour. Discussion In contrast research, we report efficient may asthma. is agreement existing knowledge. Exposure could not fully explain association between Our findings be explained by provision inadequate heating, ventilation, concentrations other biological, chemical physical contaminants. This likely modified complex interaction occupant behaviours changes built environment. confounded response rate, behavioural differences those low versus high homes, use self-reported exposures outcomes. Conclusion Energy significantly growth, although further research needed investigate characteristic factors, especially fuel poverty indoor Study implications multidisciplinary approach required prior delivery interventions aimed at improving Policy incentives are address issues alongside achieve 71 or greater, must delivered adequate heating strategies minimise dampness.
