“…In addition, the systolic blood pressure of male elderly was 143.90 ± 1.39 mm Hg, the diastolic blood pressure was 80.41 ± 0.83 mm Hg, and the female elderly was 143.85 ± 1.57 mm Hg (systolic) and 78.80 ± 0.76 mm Hg (diastolic). Zheng et al 40 found that when the variation in the environment is the same, the blood pressure of the male elderly is higher than that of the female elderly. A comparison of the two measurement time periods found that the blood pressure measured in the morning was higher than in the evening.…”

This study investigated the indoor environment of urban and rural elderly residential dwellings in Dalian and Beijing during the heating period in 2017–2018. Each dwelling was assessed for temperature, relative humidity, air pollution and biological pollution, as well as blood pressure parameters related to the health of the elderly. The results showed that the temperature in urban dwellings was higher and more stable than that in rural dwellings, due to the difference in heating devices. Indoor carbon dioxide (CO2) concentrations in some dwellings exceeded the limit. Indoor formaldehyde and volatile organic compounds (VOC) were lower than the limit values, while urban dwellings had more formaldehyde and total volatile organic compounds (TVOC) pollution than rural dwellings. For rural houses, indoor fuel combustion resulted in higher concentrations of particulate matter below 2.5 microns (PM2.5) and higher concentrations of carbon monoxide (CO). The biological pollution in rural areas was generally higher than in urban areas. The blood pressure of the elderly in rural areas was higher than that in urban areas, and blood pressure was found to be negatively correlated with room temperature and positively correlated with relative humidity. These results can provide an indicator for the improvement of housing environmental quality for older people in China.
