What causes high blood pressure?
• Family history of high blood pressure
A family history of high blood pressure is a risk factor for you. Having one or more close family members with high blood pressure before the age of 60 means you have two times the risk of having it also. A strong family history means you have 3 or more relatives who had high blood pressure before 60. It is important to understand that a family history of high bp does not mean you will have blood pressure, but it does increase your chances. A family history of high bp has been linked to other risk factors for heart disease and stroke.
• Being overweight
The prevalence of high BP and overweight/obesity was found to be 23.05% and 9.18%, respectively. High BP was positively correlated with overweight/obesity. Being a male, currently consuming alcohol, and being overweight/obese were the risk factors for high SBP and that for high DBP was overweight/obesity.
Normally, BP in childhood and adolescence fluctuates with age, height, gender, and weight.BP is also affected by other factors such as time of the day, fasting state of the person, surrounding environment, and psychological factors, which could not be taken care of in our study. One of the reasons for the high prevalence of elevated BP found in our study was probably because the data were collected either immediately before or after board examination, wherein they might have been facing exam-related stress.
• Poor diet
As per the Fourth Report on the Diagnosis, Evaluation, and Treatment of High bp in Children and
Adolescents, hypertension is diagnosed after verifying the average SBP and/or DBP on more than three distinct
occasions, which is greater or equal to the pressure level corresponding to the 95th percentile (considering
gender, age, and height percentile) of the reference population. In the present study, only two measurements of BP were taken and the last reading was considered as being the final one for analysis.
• Too much salt
High bp is the leading risk of death in the world. Unfortunately, around the world,
blood pressure levels are predicted to become even higher, especially in developing countries. High
dietary salt is an important contributor to increased blood pressure. The present review evaluates
the association between excess dietary salt intake and the importance of a population-based
strategy to lower dietary salt, and also highlights some salt-reduction strategies from selected
countries. Evidence from diverse sources spanning animal, epidemiology and human intervention
studies demonstrate the association between salt intake and HBP.
• Drinking too much alcohol
The good news is that reducing alcohol consumption is also a reliable way of improving blood pressure. Alcohol is one of the most modifiable risk factors of hypertension, which means reducing alcohol consumption is a way of reliably tackling high blood pressure. If heavy drinkers reduce their alcohol consumption by two thirds, their average systolic blood pressure drops by -3.31mmHG, and diastolic by -2.04mmHG.7
• Cigarette smoking
Study of the effect of smoking on blood pressure in normotensive men. Though smoking has
been conclusively found to cause significant cardiovascular morbidity, the literature
on the topic of affect smoking on blood pressure seems to show contradictory results.
Objective: The aim of this study was to find out the effect of smoking on blood
pressure. In a factory in South Africa, 2190 workers were examined.
A detailed history and examination were done on all the subjects. After six months, the same
subjects were examined again.
