AbstractSeasonal variations in blood pressure have been consistently reported. However, uncertainty remains about the size of the seasonal effect in different regions, and about factors that explain the differences observed across and within populations. Using data from a national panel study, we investigated seasonal variations in blood pressure in the South African adult population, and whether these variations differed across socioeconomic strata.We estimated age-specific seasonal effects on… 
Antihypertensive treatment and blood pressure trends among South African adults: A repeated cross-sectional analysis of a population panel survey
TLDR
It is inferred that diffusion of antihypertensive treatment contributed substantially to the downward trend in the prevalence of uncontrolled hypertension observed between 2008 and 2015 and the marked decrease in SBP and uncontrolled hypertension found among younger participants could not be explained by treatment nor by the changing distribution of the measured risk factors.
Geographical influence on the distribution of the prevalence of hypertension in South Africa: a multilevel analysis.
TLDR
There were significant differences in hypertension prevalence between districts and therefore the method of analysis and the results could be useful for more targeted preventative and control programmes.
Novel Overview of Seasonal Blood Pressure Variation: Review Article
TLDR
In both men and women, young and elderly, the seasonal change in BP appears to be a global phenomenon that has been documented in regions with varying climate conditions.
Quantile regression analysis of modifiable and non-modifiable drivers’ of blood pressure among urban and rural women in Ghana
TLDR
It was found that body mass index (BMI) had a significant positive effect on DBP and SBP in both urban and rural settings, with the largest effect occurring among women in the 75th quantile.
Seasonal variation in estimated cardiovascular risk in patients with type 2 diabetes.
Seasonal variation in blood pressure recorded in routine primary care
TLDR
Strong seasonality was detected for almost all patient subgroups studied and was greatest for older patients and for those with hypertension, the variation in BP between summer and winter should be considered by clinicians when making BP treatment decisions.
Seasonal variation in blood pressure: Evidence, consensus and recommendations for clinical practice. Consensus statement by the European Society of Hypertension Working Group on Blood Pressure Monitoring and Cardiovascular Variability.
TLDR
This Consensus Statement by the European Society of Hypertension Working Group on BP Monitoring and Cardiovascular Variability provides a review of the evidence on the seasonal BP variation regarding its epidemiology, pathophysiology, relevance, magnitude, and the findings using different measurement methods.
Seasonal blood pressure variation assessed by different measurement methods: systematic review and meta-analysis.
TLDR
The average BP decline in hot season is at about 5/3 (SBP/DBP) mmHg and appears to be larger in treated hypertensive patients and in older individuals.
Epidemiology of hypertension in Fulani indigenous populations—age, gender and drivers
TLDR
Age and gender variations in blood pressure and drivers of hypertension among rural Fulani population of Cameroon are described, with hypertension prevalence increased with age and was more prevalent among men than women.
Explaining population trends in cardiovascular risk: protocol for a comparative analysis of health transitions in South Africa and England using nationally representative survey data
TLDR
This study aims to examine the notions of epidemiological transition by identifying and quantifying the drivers of change in CVD risk in a middle-income African setting compared with a high-income European setting by using anonymised microdata originating from population surveys conducted in South Africa and England between 1998 and 2017.

Seasonal variation of blood pressure and its relationship to ambient temperature in an elderly population
TLDR
Seasonal variation of blood pressure is heightened in older adults and may partly explain the greater cardiovascular disease mortality of elderly subjects during the winter.
Relationship between blood pressure and outdoor temperature in a large sample of elderly individuals: the Three-City study.
TLDR
Outdoor temperature and blood pressure are strongly correlated in the elderly, especially in those 80 years or older, and during periods of extreme temperatures, a careful monitoring of blood pressure and antihypertensive treatment could contribute to reducing the consequences ofBlood pressure variations inThe elderly.
The effect of temperature on systolic blood pressure
TLDR
Indoor and outdoor temperature have independent effects on systolic blood pressure, and both should be controlled for in studies that measure blood pressure.
Seasonal variation in blood pressure is modulated by gender and age but not by BMI in a large Taiwanese population, 1996-2006.
Seasonality of cardiovascular risk factors: an analysis including over 230 000 participants in 15 countries
TLDR
CVRFs show a seasonal pattern characterised by higher levels in winter, and lower levels in summer, and this pattern could contribute to the seasonality of CV mortality.

Seasonal variation in blood pressure and its relationship with outdoor temperature in 10 diverse regions of China: the China Kadoorie Biobank
TLDR
Blood pressure was strongly inversely associated with outdoor temperature in Chinese adults across a range of climatic conditions, although access to home central heating appeared to remove much of the association during the winter months.
Seasonal changes in blood pressure in chronic kidney disease patients.
TLDR
The seasonal variation of blood pressure in CKD patients seemed to have no correlation with stage of CKD or change of body weight but was inversely associated with outdoor temperatures, suggesting that volume status might not be a key mechanism causing seasonal variation in blood pressure.
The effect of ambient temperature on blood pressure in a rural West African adult population: a cross-sectional study
TLDR
Higher ambient temperatures are associated with lower blood pressures, and 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.

TLDR
In rural China, lower outdoor temperature is strongly associated with higher mean blood pressure and hypertension prevalence as well as poorer hypertension control, and should be considered when conducting population-based hypertension surveys and providing treatment for hypertensive patients.
