Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 4
Abstract
Introduction The changes in BP with changes in weather occur through different mechanisms, in the form of increased BP during winters and decreased BP during summer. This study is planned with the objectives of assessing the seasonal variation in blood pressure and its association with nutritional status (BMI) in healthy population. Materials & Methods The study was conducted in Department of Medicine, People’s College of Medical Science & Research Center, Bhopal from December 2016 to June 2018. Normotensive individuals aged 18-80 years and giving consent were included in the study. All participants were enrolled after taking written informed consent. BP of the participants was recorded once during the predefined summer (15April-15June) and once during the winter (15December-15February) periods. BP measurement was done by Digital BP instrument (Omron) in sitting position after resting for 5 minutes. The data was compiled using Ms Excel and analysed using Epi Info 7.2 software. Observations & ResultsStatistically significant difference in mean systolic and diastolic BP during winter and summer was found (p=0.0001). Statistically insignificant association was found between BMI and SBP of winter and summer with normal (p=0.0001) and overweight (p=0.001) BMI category. Also statistically significant association was found between DBP of winter and summer with normal (p=0.067) and overweight (p=0.002) BMI category. Conclusion In hypertensive participants, significant association was found between BMI and seasonal variation in SBP and DBP in normal and overweight but no statistical association was found between BMI and SBP / DBP in underweight and obese participants.
