Indoor air pollution caused by solid fuel use for cooking affects 2.5 billion people worldwide and may elevate blood pressure (BP) and increase the burden of hypertension. Although the elderly are the most at risk of an elevated BP and hypertension, few studies have evaluated the effect of indoor solid fuel use for cooking on BP in persons over the age of 65. Therefore, in this study, we randomly selected 8067 elderly people over 65 years of age from the 2018 Chinese Longitudinal Healthy Longevity Survey to determine the impact of indoor solid fuel use on BP/hypertension. The results showed that, compared with those who cooked with clean fuel, those who cooked with solid fuel had a 1.87 mmHg higher systolic blood pressure, a 0.09 mmHg higher diastolic blood pressure, a 0.97 mmHg higher pulse pressure, and a 1.22 mmHg higher mean arterial pressure. However, we did not find any association between indoor solid fuel use and hypertension. We further observed that northern China residents, women, people aged over 90 years, hypertensive and heart patients, and those with natural ventilation in the kitchen that used indoor solid fuel experienced a greater BP impact. Replacing solid fuel with clean fuel may be an important way to lower BP. Regarding this, priority access to clean fuel should be given to the susceptible population, including the elderly aged ≥ 75 years, northern China residents, women, and hypertensive and heart patients.
室内空气污染由固体燃料烹饪引起，影响着全球 25 亿人，可能会导致血压升高，并加重高血压负担。虽然老年人面临血压升高和高血压的风险最高，但很少有研究评估烹饪用固体燃料对 65 岁以上人群血压的影响。因此，在这项研究中，我们随机选择了 2018 年中国长寿纵向研究中 8067 名 65 岁以上的老年人，以确定室内固体燃料使用对血压/高血压的影响。结果表明，与使用清洁燃料做饭的人相比，使用固体燃料做饭的人收缩压高 1.87mmHg，舒张压高 0.09mmHg，脉压高 0.97mmHg，平均动脉压高 1.22mmHg。然而，我们没有发现室内固体燃料使用与高血压之间存在任何关联。我们进一步观察到，在中国北方居住、女性、90 岁以上人群、高血压和心脏病患者以及在使用室内固体燃料的厨房中采用自然通风的人群，血压受到的影响更大。用清洁燃料代替固体燃料可能是降低血压的重要方法。关于这一点，应优先为易感人群提供清洁燃料，包括年龄≥75 岁的老年人、中国北方居民、女性以及高血压和心脏病患者。
