Key result
Winter season was associated with a mean increase in systolic and diastolic blood pressure of 11.07 and 6.79 mm Hg, respectively, compared with summer (P < .001).
Why the study?
Seasonal changes in blood pressure among normotensive women aged 18 to 40 years and their associations with environmental and physiological factors were not well quantified.
Does season affect blood pressure in normotensive women aged 18 to 40 years?
Observational (n=132)
No
Does season affect blood pressure in normotensive women aged 18 to 40 years?
Blood pressure significantly increases during winter compared to summer in normotensive young women, highlighting the need to account for seasonal variation during clinical evaluation.
Answers are grounded in this paper and cite their sources.
Seasonal BP variation in young women should not change practice; leaves open whether targeted interventions improve outcomes.
Season is one of the factors affecting blood pressure. The objectives of this study are to quantify the magnitude of seasonal changes in blood pressure among normotensive women aged 18 to 40 years and to find out the association of blood pressure variation between winter and summer with body mass index, temperature, humidity, day length, and salt intake. The study was carried out on 132 women, included 4 home visits during the seasons of spring, summer, autumn, and winter. Mean increase in systolic blood pressure (SBP)/diastolic blood pressure (DBP) in winter was 11.07/6.79 mm Hg during summer (P < .001). No significant relationship in blood pressure variation with change in environmental variables was observed. Mean increase in SBP/DBP in winter was more among underweight than individuals who were normal/overweight/obese (P < .05). There was significant increase in SBP/DBP during winter compared with summer. This seasonal factor should be considered while evaluating individual blood pressure and comparing community studies.

Sinha et al. (2009) conducted an observational in Normotensive (n=132). Winter season vs. Summer season was evaluated on Mean increase in systolic and diastolic blood pressure (MD 11.07/6.79 mm Hg, p=< .001). Winter season was associated with a mean increase in systolic and diastolic blood pressure of 11.07 and 6.79 mm Hg, respectively, compared with summer (P < .001).
