Associations between ambient temperature and blood pressure have been demonstrated in countries where the temperature varies between the seasons. This phenomenon has been overlooked in blood pressure surveys in sub-Saharan Africa. We assessed the effect of ambient temperature on blood pressure in an adult population in a West African country.
A cross-sectional survey was carried out on a rural Ghanaian population, investigating the effect of ambient temperature on blood pressure in 574 randomly sampled adults aged between 18 and 65 years.
There was a significant inverse relationship between ambient temperature and systolic (SBP) (p < 0.019) and diastolic blood pressure (DBP) (p < 0.036). SBP fell by 5 mmHg per 10 degrees C rise in ambient temperature.
Higher ambient temperatures are associated with lower blood pressures. To enhance comparability of data from epidemiological surveys, ambient temperature should be recorded for each blood pressure reading and findings standardised to a fixed ambient temperature.
在气温随季节变化的国家，环境温度与血压之间的关联已得到证实。撒哈拉以南非洲地区的血压调查中忽略了这一现象。我们评估了西非一个国家成年人群中环境温度对血压的影响。
对加纳农村人口进行了一项横断面调查，调查环境温度对574名年龄在18至65岁之间随机抽样成年人血压的影响。
环境温度与收缩压（SBP）（p < 0.019）和舒张压（DBP）（p < 0.036）之间存在显著负相关。环境温度每升高10摄氏度，收缩压下降5 mmHg。
较高的环境温度与较低的血压相关。为提高流行病学调查数据的可比性，每次测量血压时都应记录环境温度，并将结果标准化到固定的环境温度。
