室内环境与高龄者血压的关联性——以大连市供暖季为例

对中国大连市供暖季住宅室内环境与高龄者血压的关联性进行了调查研究，具体包括住宅热湿环境（温度、相对湿度）、化学污染（CO₂、CO、甲醛和TVOC）、物理污染（PM_2.5）和生物污染（附着真菌）与高龄者血压的关联性.研究表明，城市和农村住宅供热方式不同是导致住宅室内热环境舒适度差异的主要原因.在大连农村，处于室外的厕所与室内形成的大温差使得农村高龄者患心血管疾病的诱发风险比城市更高.城市高龄者的平均血压比农村低且波动小.城市住宅室内温湿度与血压均存在关联（P<0.01），农村室内温湿度对血压的影响程度不如城市明显.另外，室内空气质量参数并未发现与血压存在显著关联.

Association between indoor environment and blood pressure in the elderly——A pilot study in Dalian during heating season

This study investigated the association between elder dwellers' blood pressure and indoor environment conditions including dwellings' thermal and humid environment (temperature, relative humidity), chemical pollution (CO₂, CO, formaldehyde and TVOC), physical pollution (PM_2.5) and biological pollution (adherent fungi) during a heating season in Dalian, China. The results showed that the heating type was the main factor causing the difference of indoor thermal comfort between urban and rural dwellings. In rural Dalian, the large temperature step-changes between outdoor and indoor in toilets made the risk of cardiovascular disease higher for elder dwellers' than that for urban elder dwellers. The mean blood pressure of urban elderly was lower than that of rural areas with smaller variation. There was a significant correlation between indoor temperature and humidity in urban dwellings and elder dwellers' blood pressure (P<0.01). The influence of indoor temperature and humidity on blood pressure in rural area was less obvious than that in urban area. In addition, no significant correlation was found between indoor air quality parameters and blood pressure.
