Background Awareness of cardiovascular diseases (CVDs) and risk factors has been linked to the prevalence of CVDs.
Objective The current study was conducted to compare the prevalence of CVDs risk factors among male and female populations in Arar City, Northern Saudi Arabia.
Participants and methods A cross-sectional study was carried out in three randomly chosen primary health care centers in Arar City. A total of 401 Saudi nationals were included.
Results Most (59.1%) of female and 44.5% of males did not check their blood glucose (P<0.05). The majority (61.7%) of female and 44.1% of males did not check their blood pressure (P<0.05). Most (98.7%) of females and 50.6% of male were nonsmokers. Most (82.6 and 80.5%) of males and females ate fruits less than three times per week, 69.6% of females and 53.5% of males performed light physical exercise, whereas 12.1% of males and 7.1% of females did not perform physical exercise at all (P<0.05). Between male and female, the mean BMI was 27.49±5.4 and 26.23±13.4, the mean intake of fruits per week was 2.80±1.73 and 3.77±1.99 days, and the mean vegetable intake per week was 4.19±1.97 and 5.87±1.85 days, with no significant difference (P>0.05).
Conclusion and recommendations The prevention of CVDs is based on the control of several risk factors and associated conditions. Specific studies or programs are needed to raise the awareness of what CVDs are, its risk factors, and how to control or modify it.

| Introduction|| |
Cardiovascular diseases (CVDs) are considered the first cause of mortality at the global level; each year, more people die of CVDs than from any other cause. According to a WHO report, an estimated 17.3 million people died of CVDs in 2008, constituting 30% of all global deaths; it was estimated that ∼23.6 million people will die of CVDs, mainly from heart disease and stroke, by 2030 . Owing to rapid demographic and epidemiologic transitions, life expectancy is increasing, which leads to an increased health burden of noncommunicable diseases (NCDs) .
The leading risk factors for the development of NCD are high blood pressure, increased level of cholesterol, inadequate intake of fruit and vegetables, overweight or obesity, lack of physical activity, and smoking . Hypertension affects approximately one billion people worldwide, and it is expected to increase to 1.5 billion by the year 2025 . Modern lifestyle associated with easy access to food, lack of exercise, sedentary lifestyles, calorie dense foods, and excessive television viewing contribute to development of NCDs .
CVDs are a growing health concern in the middle-eastern region and the Gulf Council Countries (GCC) ,,. Among the six GCC countries, CVD was estimated to account for 45% of deaths overall. Oman and Kuwait had the highest proportion of deaths attributed to CVD (49 and 46%, respectively); Saudi Arabia, United Arab Emirates, Bahrain, and Qatar (42, 38, 32, and 23%, respectively) also had a significant proportion of CVD deaths (WHO country profiles) .
Studies in Saudi Arabia estimated that the prevalence of hypertension is ∼49%, whereas coronary heart disease (CHD) is between 5 and 6% . Regional studies (e.g. Gulf RACE)  have identified a set of common risk factors for CVD, which include the following: hypertension, diabetes, dyslipidemia, obesity, smoking, physical activity, poor diet, and alcohol consumption.
Studies in Saudi Arabia suggest that the presence of these risk factors, particularly hypertension, obesity, and diabetes, continue to rise each consecutive year ,,. The CVD risk profile differs between men and women; for example, men are more likely to smoke but women are more likely to be obese ,. Moreover, men are more likely to have dyslipidemia, but women are more likely to have type 2 diabetes .
In the study by Khot et al. , the results showed that among patients with CHD, at least one of the four conventional risk factors was present in 84.6% of women and 80.6% of men. In younger patients (men 55 years and women 65 years) and most patients presenting either with unstable angina or for percutaneous coronary intervention, only 10–15% of patients lacked any of the four conventional risk factors. Premature CHD was related to cigarette smoking in men and cigarette smoking and diabetes in women. Smoking decreased the age at the time of CHD event (at trial entry) by nearly one decade in all risk factor combinations .

Study type and sitting
A cross-sectional study was carried out in three randomly chosen primary health care centers in Arar City, the capital of the Northern Province of KSA, during the period from 1 May to 30 October 2016.
A total of 401 Saudi nationals aged 18–93 years were included in the study.
Data were collected by means of personal interview with the sampled population using a predesigned questionnaire covering the following items:
- Sociodemographic characteristics, including age, sex, educational, marital status, and occupation.
- Smoking status and certain types of diseases that suggested to effect cardiovascular system diseases such as diabetes mellitus (DM) and hypertension, history of checking of blood pressure, history of checking of blood glucose, frequency of eating vegetables and fruits, excess coffee drinking, and performing physical exercise.
- Anthropometric examination included height and weight measurements with the use of a calibrated balance beam scale and a wall-mounted stadiometer and calculation of BMI. Normal weight was defined as BMI less than 25 kg/m2, overweight as 25 less than or equal to BMI less than 30 kg/m2, and obesity as BMI more than or equal to 30 kg/m2 .
- Blood sample is drawn under complete septic conditions to determine random blood glucose level. A person is considered diabetic if random blood sugar was more than or equal to 200 ml/dl .
This study was reviewed and approved by the Research Ethics Committee of Faculty of Medicine, Northern Border University. Participants were informed that participation is completely voluntary, and written consent was obtained from each participant before being subjected to the questionnaire and after discussing the objective with the participants. No names were recorded on the questionnaires. Adequate training of data collectors took place to ensure protection of confidentiality, and all questionnaires were kept safe.
Collected data were coded and analyzed using statistical package for the social sciences (SPSS, version 15; SPSS Inc., Chicago, Illinois, USA). The χ2-test and independent samples t-test were used as tests of significance, and differences were considered significant at P value 0.05 or less.

| Discussion|| |
Awareness of CVD risk factors has been linked to taking preventive action. CVD is a class of diseases that involve the heart or blood vessels. They are the leading cause of death globally, except in Africa . Deaths, at a given age, from CVD are more common and have been increasing in much of the developing world, whereas rates have declined in most of the developed world since the 1970s . CVD due to narrowing of blood vessels might not be diagnosed until underlying condition worsens to the point of heart attack, chest pain (angina), stroke, heart failure, or sudden cardiac death. It is therefore important to watch for cardiovascular symptoms . Among the six GCC countries, CVD was estimated to account for 45% of deaths, overall. Oman and Kuwait had the highest proportion of deaths attributed to CVD (49 and 46%, respectively); Saudi Arabia, United Arab Emirates, Bahrain, and Qatar (42, 38, 32, and 23%, respectively) also had a significant proportion of CVD deaths (WHO country profiles) .
The current study is a cross-sectional study carried out in three randomly chosen primary health care centers in Arar City, Northern Province of KSA. The study was conducted to compare the prevalence of CVDs risk factors among male and female populations in Arar District, Northern Saudi Arabia. A total of 401 Saudi nationals (61.6% males and 38.4% females) aged 18–93 years were included in the study (48.1% of them aged between 20 and 30 years). Data were collected by means of personal interview with the sampled population using a predesigned questionnaire. Of the numerous causes of CVD, the predominant ones identified are as follows: obesity, DM, and hypertension, in addition to low vegetable and fruit intake, smoking, stress exposure, and lack of physical activities. In this study, we review the contribution of each of these factors toward the existence of CVD in Saudi Arabia.
The study showed the percentages of these factors as smoking in 30.9%, no checking of blood glucose in 50.1%, no checking of blood pressure in 50.9%, obesity in 21.7%, overweight in 34.4%, hypertension in 8.7%, and DM in 11.7%. This was supported by a study conducted on urban and rural population in Tamil Nadu; it found the proportion of male and female smokers was 4.9 and 3.7%, respectively, in urban areas and 4.8 and 6.2%, respectively, in rural areas, and the proportion of overweight was 73.8 and 40.6% in urban and rural areas, respectively. Nearly 37.2 and 23.6% of the urban population and 6.9 and 9.0% of the rural population had systolic and diastolic hypertension, respectively . Our results were more or less in accordance with the results of a study conducted in the USA  that showed among 115.9 million US adults aged more than or equal to 35 years, 40% had hypertension, 20% of the patients smoked, and 11% had diabetes, all counted as risk factors of CVD. The same study also reviewed increasing blood pressure increased the risk for CVD. Our findings were also approved by a study on Asian population which revealed that the most important risk factors of CVD were hypertension, smoking, total cholesterol in serum, and finally DM . Midha et al.  reported a prevalence of hypertension of 32.8% in urban population and 14.5% in rural population. De et al.  reported a prevalence of hypertension in 52.9% of urban and 35% of rural populations. Gupta et al.  reported the prevalence of hypertension to range between 20 and 40% in urban adults and 12 and 17% among rural adults.In Saudi Arabia, studies suggest that the presence of risk factors, particularly hypertension, obesity, and diabetes, continue to rise with concomitant rise in the prevalence of different CVDs each consecutive year ,,.
In our study, between male and female populations, the mean intake of fruits per week was 2.80±1.73 and 3.77±1.99 days, and the mean vegetable intake per week was 4.19±1.97 and 5.87±1.85 days, with no significant difference (P>0.05). In urban and rural populations in Tamil Nadu, the mean intake of fruits per week was 2.70±1.95 and 3.88±2.21 days and the mean vegetable intake per week was 4.72±1.97 and 5.91±1.84 days . WHO reports the prevalence of inadequate fruits and vegetable consumption was higher among females than males in the south East Asia region .
In our results, most females (98.7) were nonsmokers as compared with 50.6% of males. Mean BMI±SD was higher in males than females (27.49±5.43 vs 26.23±13.46). In the study by Ibrahim et al. , the risk factors of CHD were compared among medical students in King Abdulaziz University, Jeddah, Saudi Arabia; it was found that the CVD risk profile differs between males and females; for example, males are more likely to smoke but females are more likely to be obese .
Conclusion and recommendations
The prevention of CHD is based on the control of several factors associated with a disease or clinical condition. Several studies have shown that good metabolic control and multifactorial risk factor reduction significantly lower the coronary risk in these patients. Specific studies or programs are needed to raise the awareness of the risk factors and what CVDs are.
