Back ground: Hypertension is one of the major prevalence chronic diseases in the world and it’s greatly increase particularly in developing countries (Include Iraq) especially in women. A number of risk factors for increased the blood pressure include obesity resistance of insulin, excessive alcohol intake, elderly, sedentary life style, stress decrease intake of potassium and calcium, many of this factors are additives such as obesity and alcohol intake.
Aim of the study: The study was conducted with the aimed of determining the prevalence of Hypertension among woman and identifying life style related risk factor and we choose women because this town become endemic area with hypertension based on previous survey.
Patient: This is a randomize prospected, clinical study it was conducted in AL-Diwaniya teaching hospital, medicinal department, and emergency department. This study started at December 2015, this approved medical ethical community at AL-Kufa University.
Materials: There is considerable guidance about the range of appropriate devices for measuring blood pressure and about their maintenance and periodic recalibration local medical physics and biomedical/clinical engineering departments can often give further advice.
Methods: Sample of 60 case women in Al-Diwaniya city was chosen randomly all the women present in the hospital of AlDiwaniya Teaching Hospital at the time of visiting. Where interview according to specialise questionnaire... height.... weight; Blood pressure were measured.
Results: The prevalence lifestyle risk factor among the study population was as follow: Physical inactivity (65.4%) (Over weight 39.4%), (obesity 35.3), (OCP 16.4), (salty diet 16%), (fatty diet 13.2%) drug intake {mostly (NASIDs) 11.4}, (coffee intake 7.4%), (smoking 1.5%). A significant associated was found between some lifestyles risk factor and hypertension, these were drug intake and BMI, while no sign associated was found between other risk factor and hypertension which were, fatty diet, physical activity, coffee intake and OCP intake.
Conclusion: The prevalence of Hypertension was within the range of that reported for women in Iraq. A significant association was found between certain life style risk factor. Early detection for hypertension and education health program regarding life style behavior was high recommended.

Hypertension is one of the important preventable causes of premature mortality and morbidity in the UK. Hypertension is a main risk factor for hemorrhagic and ischemic stroke, heart failure, myocardial infarction, cognitive decline, chronic kidney disease and premature death. Hypertension left without treatment is usually associated with a progressive rise in blood pressure. The vascular and renal damage that may cause culminate in a treatment-resistant state [1]. In many people with established primary hypertension, increased total peripheral resistance accounts for the increase in pressure while cardiac output remains within normal. There is fact that some younger people with 'borderline hypertension or prehypertension' have increase cardiac output, an increase heart rate and normal peripheral resistance, called hyperkinetic borderline hypertension [2] (Table 1).
Hypertension results from a complex interaction of environmental factors and genes. Numerous common genetic variants with small influences on blood pressure have been identified as well as some rare genetic variants with large effects on blood pressure, but the genetic basis of hypertension is still poorly understood [4]. Secondary hypertension results from an identifiable cause. Kidney disease is the most common secondary cause of hypertension. Hypertension can also be caused by Endocrine conditions such as, hyperthyroidism, hypothyroidism, acromegaly, Conn’s syndrome or hyperaldosteronism, hyperparathyroidism and pheochromocytoma.
Other causes of secondary hypertension include obesity, sleep apnea, pregnancy, coarctation of the aorta, excessive liquorice consumption and certain prescription medicines, herbal remedies and illegal drugs. Arsenic exposure through drinking water has been shown to correlate with elevated blood pressure [5].
Risk Factors of Hypertension (Being overweight or obese, Too much salt (sodium) in your diet, too little potassium in your diet, not being physically active ‘drinking too much alcohol, stress‘ Non-steroidal Antiinflammatory Drugs (NSAIDs), Cough and Cold Medications, certain chronic conditions, a diet low in vitamin D [6-14].
Management of Hypertension IncludesLifestyle changes to treat high blood pressure no matter what medications your doctor prescribes to treat your high blood pressure, you'll need to make lifestyle changes to lower your blood pressure. Your doctor may recommend several lifestyle changes, including: eating a healthier diet with less salt (the Dietary Approaches to Stop Hypertension, or DASH, diet) [15].
Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Evidence suggests that reduction of the blood pressure by 5 mmHg can decrease the risk of stroke by 34%, of ischaemic heart disease by 21%, and reduce the likelihood of dementia, heart failure, and mortality from cardiovascular disease [16]. There are many classes of antihypertensive, which lower blood pressure by different means. Among the most important and most widely used drugs are thiazide diuretics, calcium channel blockers, ACE inhibitors, angiotensin II receptor antagonists (ARBs), and beta blockers [17].
Materials and MethodsThis is a randomize prospected, clinical study it was conducted in Iraqi teaching hospitals, medicinal department, and emergency department. This study started at December 2015, this approved medical ethical community at University of Kufa.
MaterialsThere is considerable guidance about the range of appropriate devices for measuring blood pressure [18]. And about their maintenance and periodic recalibration Local medical physics and biomedical/clinical engineering departments can often give further advice [19].
Mercury sphygmomanometer: The mercury sphygmomanometer has been used for the traditional measurement of blood pressure. It is reliable and provides the reference standard for indirect measurement. However it is bulky, fragile and there are particular safety and economic concerns about the toxic effects of mercury. Mercury is being phased out of clinical use and mercury sphygmomanometers have already been removed from clinical areas in hospitals and primary care. Thus, alternatives to mercury sphygmomanometer are now required for routine clinical use [20]. Non-mercury devices that operate in a similar way to the traditional mercury column devices are available and provide a suitable alternative to mercury devices when manual auscultation is required to measure blood pressure.
Aneroid sphygmomanometers: Aneroid sphygmomanometers measure pressure using a lever and bellows system. They may be less accurate than mercury sphygmomanometers and their alternatives, especially over time. Using the manual auscultation technique they are subject to the same sources of observer error [21].
Automated devices: Automated devices are increasingly being used in hospitals and primary care. All sphygmomanometers need regular maintenance. Rubber tubing can crack and leak making cuff deflation hard to control, underestimating systolic and overestimating diastolic readings. Faulty valves can cause similar problems [21].
MethodsSample of 60 case women in Al-Diwaniya city was chosen randomly all the women present in the hospital of Al-Diwaniya Teaching Hospital at the time of visiting. Where interview according to specialise questionnaire... height.... weight; Blood pressure were measured. The whole sample size was 60 participants; the only excluded character was pregnancy.
Statistical AnalysisStatistical analyses were performed using SPSS 16.0. An expert statistical advice was consulted for tests used. Data of quantitative variable were expressed as mean ± SEM. Differences in each variable through treatment intervals in the same group were compared using paired sample students test. In all tests, P < 0.05 was considering to be statistically significant unless another level were stated.
ResultsIn this table 2 below there were no significant between demographic patients with hypertension.
The Prevalence Lifestyle Risk Factor among the Study PopulationPhysical inactivity (65.4%) (Over weight 39.4%), (obesity 35.3), (OCP 16.4), (salty diet 16%), (fatty diet 13.2%) drug intake {mostly (NASIDs) 11.4}, (coffee intake 7.4%), (smoking 1.5%). A significant associated was found between some lifestyles risk factor and hypertension, these were drug intake and BMI, while no sign associated was found between other risk factor and hypertension which were, fatty diet, physical activity, coffee intake and oral contraceptive pill intake.
DiscussionHypertension is a major risk factor for stroke (ischaemic and hemorrhagic), myocardial infarction, heart failure, chronic kidney disease, peripheral vascular disease, cognitive decline and premature death. Untreated hypertension is associated a progressive rise in blood pressure, often culminating in a treatment resistant state due to associated vascular and renal damage. Blood pressure is quantified as diastolic and systolic pressures measured in millimeters of mercury (mmHg). The diastolic pressure represents the pressure during ventricular relaxation in diastole whereas the systolic pressure represents the peak pressure due to ventricular contraction during systole. Either or both pressures have specified upper limits of normal and elevation in either or both pressures are used to define hypertension [22].
Effect of Physical Inactivity on HypertensionThe present study show a significant effect of this risk factor (p-value<0.05), this findings are in agreement with results of study, which stated that people who are inactive tend to have higher heart rates [23]. The higher your heart rate, the harder your heart must work with each contraction and the stronger the force on your arteries. Lack of physical activity also increases the risk of being overweight.
Effect of Smoking on HypertensionThe result of current study show is no significant effect of smoking on hypertension, this finding are in consistency with results of study, which stated that smoking temporarily raises blood pressure and increases your risk of damaged arteries [24]. The use of tobacco can be devastating to your health, especially if you're already at risk for high blood pressure. Secondhand smoke exposure to other people's smoke increases the risk of heart disease for nonsmokers.
Effect of Overweight and Obesity on HypertensionThe present study show a significant effect of these risk factors on hypertension (p-value <0.o5), this finding are in similarity with study which stated that being overweight increases your chances of developing high blood pressure [24]. A body mass index between 25 and 30 is considered overweight. A body mass index over 30 is considered obese. About two-thirds of U.S. adults are overweight or obese. About one in three U.S. children ages 2 to 19 are overweight or obese. Excess weight increases the strain on the heart, raises blood cholesterol and triglyceride levels, and lowers HDL (good) cholesterol levels. It can also make diabetes more likely to develop. Losing as little as 10 to 20 pounds can help lower your blood pressure and your heart disease risk. To successfully and healthfully lose weight and keep it off most people need to subtract about 500 calories per day from their diet to lose about one pound per week.
Effect of Contraceptives on HypertensionThis study show no significant effect of this risk factor, this finding are in consistency with study which stated that oral contraceptive and postmenopausal therapy may be induce HTN by many mechanisms such as rennin angiotensin system increase substrate that lead to increase in amount of angiotensin and cause decrease in suppression of rennin release, sodium & water retention [25]. Numerous studies show that chronic administration of contraceptive containing estrogen & progesterone may increase blood pressure &the risk of cardiovascular.
Effect of Salt Diet Intake on HypertensionThe current study is a significant effect of this risk factor (<0.05), this finding are is similarity with study which stated that a high salt diet intake disrupts the natural balance in the body [26]. This causes fluid retention which increases the pressure against blood vessels. For every one gram cut from our average daily intake, there would approximately 6000 fewer deaths from strokes and heart attacks every year.
Effect of Fatty Diet Intake on HypertensionThe current study is no significant effect of this risk factor. This finding is in agreement with studies which stated that consumption of food that are high in fat result in increased absorption of cholesterol [27]. Fatty foods also contain high amount of triglyceride. Fat molecule is similar to cholesterol and saturated fats. Fat food restaurants are major supplier of fatty foods in United States. Fat consumption yields twice the amount of calories in comparison to protein or carbohydrate intake. Fatty foods affect blood pressure by influencing the rate of atherosclerosis (increase thickness of arterial walls that result from the accumulation of cholesterol within the arterial wall).
Effect of Drug Uses on HypertensionThe current study show a significant effect of this risk factor on hypertension (p-value <0.05), this finding are in similarity with finding of study which stated that a number of medication & other condition can causes HTN and called secondary hypertension [27]. For example cough &cold medication (including decongestant), analgesic & birth controls pill can cause blood pressure to increase.
Effect of Coffee Intake on HypertensionThe present study show no significant effect of this risk factor on hypertension, this finding are in similarity with result of study which show that according to studies take on women, the risk of hypertension may be lower in coffee abstainers [25]. Studies show that coffee intake around 5 cups per day cause small elevation in BP (approximately 2/1 mmhg) when compared to abstinence or use of decaffeinated coffee. However there are many other substance in coffee such as polyphenols, soluble fiber and potassium, which could exert a beneficial effect in the cardiovascular system. Although the precise nature of the relation between coffee and BP is still unclear, mostevidence suggest that regular intake of caffeinated coffee does not increase the risk of hypertension.
ConclusionFrom the results of this study we can conclude the following: the prevalence of Hypertension was within the range of that reported for women in Iraq. A significant association was found between certain life style risk factor. Early detection for Hypertension and education health program regarding life style behavior was high recommended.
