Undiagnosed hypertension in a rural community in Sudan and association with some features of the metabolic syndrome: how serious is the situation?

BACKGROUND: Hypertension is the leading risk factor for death and disability globally. Its prevalence is increasing worldwide especially in low and middle income countries. It is considered a silent killer because it has no specific symptoms and thus can go unnoticed for many years, only presenting for the first time with serious complications. The situation of undiagnosed hypertension in Sudan has not been fully investigated before. OBJECTIVE: To determine the prevalence of undiagnosed hypertension in the rural communities of River Nile State (RNS), Sudan and to assess the associated risk factors. METHODS: A cross-sectional community-based study, in which 1099 volunteer adult participants from the rural communities in RNS, not known to be hypertensive, were included. Blood pressure was measured as well as anthropometric measurements. The WHO stepwise approach for non-communicable diseases surveillance was used for data collection. A p value below 0.05 was considered statistically significant. RESULTS: There were 461 males (41.9%) and 683 females (58.1%). The male to female ratio was 1:1.4. The age range was 18-90 years, with a mean age of 39.6 (STD ± 15.9). The prevalence of undiagnosed hypertension was 38.2%, with a prevalence of 36.7% among males and 39.3% among females. There were significant associations between undiagnosed hypertension and increasing age, obesity, illiteracy and diabetes mellitus (p < 0.05). CONCLUSION: This study uncovers a hidden epidemic of a silent killer in the rural communities of RNS. Urgent interventions are required to address this serious health epidemic.

Knowledge and Awareness of Mothers of Asthmatic Children and Its Impact on Asthma Control: A Cross-Sectional Study From Qassim Region, Saudi Arabia.

Introduction Asthma, a common chronic airway disorder, presents challenges in diagnosis and management, particularly in children. Triggers include allergens and pollutants, necessitating lifestyle modifications and pharmacological treatments. Severe cases require tailored management. International guidelines provide stepwise approaches, while the Saudi Thoracic Society offers comprehensive recommendations, emphasizing gradual treatment phases and thorough clinical assessment. This study aimed to evaluate the knowledge and awareness levels among mothers of asthmatic children in Qassim region, Saudi Arabia. Methodology This cross-sectional study was conducted among 422 mothers with asthmatic children at primary healthcare centers in Qassim, Saudi Arabia. Mothers' knowledge of asthma was assessed using an online questionnaire. Participants were selected via a convenient non-probability sampling technique. Data was cleaned in Excel and analyzed using IBM SPSS Statistics for Windows, Version 29 (Released 2023; IBM Corp., Armonk, New York, United States). Participants were selected via a convenient non-probability sampling technique. Necessary statistical tests like Chi-square and Fisher's exact test were applied. Results Our study involved 422 mothers of asthmatic children in Saudi Arabia. Most participants were aged 35-44 years (50.7%) and Saudi nationals (92.2%), with 88.2% having one asthmatic child. Regarding awareness, exposure to air pollution (97.9%) and cigarettes (93.4%) were well-recognized factors. Pediatricians (50.5%) and family physicians (42.2%) were primary information sources. Concerning attitudes, most mothers disagreed with the harmful effects of inhalers (82.5%-92.7%) and advocated for avoiding smoking near asthmatic children (94.8%). Our study revealed that 94.5% of mothers of asthmatic children possessed a good level of knowledge about asthma in their children, while 5.5% demonstrated a low level of knowledge. Notably, mothers with good knowledge levels reported fewer emergency room visits (p=0.011) and hospitalizations (p=0.001). Predictors of good-level knowledge included higher education (adjusted odds ratio (AOR) =4.080, p=0.007) and absence of smoking relatives (AOR =0.222, p=0.005), while pet ownership was associated with lower knowledge (AOR =0.257, p=0.030). Conclusion Our study underscores the importance of maternal knowledge in pediatric asthma management. Good awareness levels were observed regarding key risk factors and appropriate attitudes toward medication use. Higher education and absence of smoking relatives were significant predictors of mothers' knowledge of the disease.

Job Satisfaction and Associated Factors Among Primary Healthcare Workers: A Cross-Sectional Study From Qassim Region, Saudi Arabia.

Background The healthcare sector is one of the most important sectors in any country. Any disruption in the productivity of the workforce majorly affects healthcare entities. Job satisfaction directly interferes with the individual's productivity. Hence, the job satisfaction of healthcare workers (HCWs) is a fundamental issue to discuss, investigate, and study to improve the outputs to their maximal levels, especially if limited studies are done in this regard. Methodology A descriptive, cross-sectional, facility-based study was conducted among 302 HCWs in 30 primary healthcare centers (PHCCs) in the Qassim region, Saudi Arabia, using a pretested, validated, electronically self-administered "Satisfaction of Employees in Health Care" (SEHC) questionnaire. Our sample included physicians, nurses, pharmacists, dental workers, and lab and radiology technicians. Data were analyzed using SPSS version 29 (IBM Corp., Armonk, NY). Results The mean score of the overall perception of job satisfaction in primary healthcare staff was 3.9 (±1.01) out of one to five scale questions. This implies a high satisfaction in 71.2% (n = 215) of the sample. Nurses expressed the highest satisfaction with their roles, comprising 26.5% (n = 80) who reported high satisfaction. Second in line were physicians, demonstrating high satisfaction levels with 14.2% (n = 43). The third place was for lab technicians, 4.6% (n = 14) of whom expressed high satisfaction. Many factors were found to be significantly statistically associated with job satisfaction, including gender (p = 0.015), age (p = 0.001), job rank (p = 0.027), number of patients seen per day (p = 0.002), type of primary healthcare duty (p = 0.042), and health workers' years of experience (p = 0.000). Conclusion The study revealed that HCWs at primary healthcare facilities in the Qassim region, Saudi Arabia, were highly satisfied with their jobs. Significant statistical relationships were found between job satisfaction and factors such as years of experience, type of duty in PHCCs, and number of attendees per day. To improve HCWs' job satisfaction, we recommend that they receive additional organizational support and response to feedback, a reduced workload achieved through increased staffing, and flexible work shifts. We also recommend investigating satisfaction in the private healthcare sector.

Parenting Style Frequency and Their Sociodemographic Determinants in Buraidah City, Qassim, Saudi Arabia.

Background Three parenting styles still form the foundation for today's research into childhood development. The natural mode of parenting falls somewhere among Baumrind's parenting styles (authoritative, authoritarian, and permissive). Due to the lack of research that integrates the relationship between parenting styles and socioeconomic status in Saudi Arabia, we decided to study different types of parenting styles and their relationship with sociodemographic status. Objective This study aimed to estimate the frequency of parenting styles among adolescent children's parents in Buraidah City, Qassim, during the year 2021. Methods A descriptive cross-sectional community-based study was conducted among 496 parents. A structured questionnaire was used to collect data. The Parenting Style Dimension Questionnaire (PSDQ) was used to identify the parenting style of each participant. Data were analyzed using the Epi Info software version 7.2.5 (Centers for Disease Control and Prevention, Atlanta, GA, USA). Results Among the surveyed parents, there were 250 (50.4%) males, and the mean age was 36.7 (±10.6) years. The majority (390, 78.6%) live in a nuclear family with a family size ranging from four to six members (285, 57.5%). A total of 451 (90.9%) parents were educated in secondary school and above. In this study, the common parenting style was the authoritative style (380, 76.6%). The two sociodemographic factors found to be statistically correlated with authoritative style were big family size (P=0.014) and the husband's income (P=0.012). Conclusion The study revealed that the authoritative parenting style was the dominant type among younger parents. However, no factors affect the parents' style except family size and the husband's income. It is important to develop parenting education programs to provide parents with the necessary skills and abilities to deal with their children.

Foot care knowledge, attitude and practices of diabetic patients: A survey in Diabetes health care facility.

Background: Among diabetes complications, diabetic foot disease (DFD) is the most common and the most preventable complication. This study aimed to assess the level of knowledge, attitude and practice of foot care among type two diabetes mellitus (DM) patients attending the Diabetic and Endocrine Center at King Fahad Specialist Hospital in Buraydah-Qassim region, Saudi Arabia. Methods: A descriptive cross-sectional facility-based study was conducted randomly among type two diabetic patients; respondents were 260 patients. Participants were interviewed using a pretested semi-structured questionnaire. Results: Of the total studied patients, 54.2% were males with median age of 58 years. Majority 56.5% of patients had good knowledge and 56.9% had good practices regarding diabetic foot care. The mean knowledge score was 4.0 (±1.86) out of 6. About 39.2% of participants received advice regarding foot care from their physicians. Only 41.5% of the patients examined their feet daily, 41.9% carefully dried between the toes after washing, and 40.8% were walking barefooted at home. About 68.5% of the participants had a history of diabetic foot complications. A significant statistical association was found between the good knowledge and patients' age, educational level, family monthly income, duration of diabetic illness and having prior knowledge regarding foot care (P-value <0.05). While, good practice of the participants towards the diabetic foot care was found to be statistically associated with the family monthly income and the prior knowledge regarding diabetic foot care (P-value <0.05). Conclusion: Our study revealed that more than half of the participants had good knowledge and practices of diabetic foot care. However, the role of physicians and medical staff in annual foot examination and health education is crucial. An awareness program implementation for diabetic foot care is highly needed.

Online family medicine training amid the COVID-19 crisis in KSA: A mixed-method study.

Objective: Literature on the perceptions and experiences of postgraduate trainees and trainers regarding online methods of learning is scarce. We aimed to assess the perceptions and experiences of family medicine trainees and trainers regarding online learning during the novel coronavirus (COVID-19) pandemic in Qassim, KSA. Methods: This was a mixed-method study involving trainees and trainers at the Family Medicine Academy, Qassim. Quantitative data were collected using structured questionnaires from 36 trainees and 26 trainers. Qualitative data were collected through in-depth interviews with trainees (n = 4) and trainers (n = 3). Descriptive analysis was performed on the quantitative data, while thematic analysis was performed on the qualitative data. Results: Among the trainees, 39% perceived online learning to be less effective than traditional classroom learning. Moreover, 61% and 64% of the respondents were concerned about the motivation and quality of online learning, respectively. Lack of direct contact with other students was the most commonly perceived concern among 80% of trainees. Among the trainers, the majority were either dissatisfied or neutral about participation and interaction, speakers' and students' motivation, the quality of online learning, and the online teaching experience. Qualitative data showed that online methods provide the advantages of learning from other institutions and flexibility, as well as a viable alternative during crises. However, there were issues with interaction, participation, and trainers' online teaching skills. Conclusion: Online learning has provided an opportunity to continue training during the COVID-19 crisis. However, there are widespread concerns regarding its effectiveness among trainees and trainers. There is a need to train trainers in online teaching and adopt interactive methods to increase trainees' interaction, motivation, and participation.

Impact of COVID-19 on Antenatal Care Utilization Among Pregnant Women in Qassim, Saudi Arabia.

Background and objectives Coronavirus disease 2019 (COVID-19) pandemic has affected routine service delivery which might affect antenatal care (ANC) utilization among pregnant women. This study aimed to assess the proportion of missed appointments among pregnant women in the Qassim region of Saudi Arabia during the COVID-19 pandemic. Methods A facility-based cross-sectional survey was conducted among pregnant women admitted for delivery in Maternity and Children Hospital (MCH), Buraidah. Data were collected on socio-demographics, obstetric history, missed appointments and reasons for missing the appointment. Analysis was carried out in Statistical Package for the Social Sciences (SPSS), version 21.0 (IBM Corp., Armonk, NY). Medians with interquartile range (IQR) were presented for continuous variables and frequency and proportions for categorical variables. Logistic regression was used to assess the factors associated with the missed appointment. Results A total of 400 women were included in the study. About one-third (30%) of the women had missed at least one ANC appointment in their current pregnancy. The most common reasons for missing the appointments in primary care and hospitals, respectively, were: fear of infection 52% and 47%, facility not working usual 25% and 7.5%, fear of infection to child 19% and 17%. Family size and gravidity were the significant factors associated with missed appointments in our study. Conclusions Nearly one-third of women missed their ANC appointments during the COVID-19 pandemic. Major reasons were related to COVID-19 fear and its effect on services. This calls for proper health communication in the general population and delivering routine care with evidence-based guidelines to maintain continuity of care.

Satisfaction Of Trainees With Family Medicine Training Program: A Cross Sectional Study From Qassim, Saudi Arabia.

BACKGROUND: Focus on quality of postgraduate training has increased. One of the quality indicators is satisfaction of trainees with the residency programs. We aimed to assess the level of satisfaction of Saudi Board family medicine trainees with training program in Qassim. METHODS: Anonymized online survey, using a structured questionnaire, was conducted among the current family medicine residents (n=60) in Qassim in 2019. Descriptive analyses were carried out to calculate frequencies of the responses. Satisfaction level was compared between basic (R1, R2) and advance (R3, R4) levels using Chi-square test. RESULTS: About 67% (40) were basic level trainees. A higher proportion (>80%) of trainees was satisfied with the program director. Satisfaction with trainers ranged 45% to 85% for different items. About 79% of the trainees were satisfied with the training program organization. In the domain of training processes higher proportion (73-83%) was satisfied with supervision and feedback while a lower proportion (63- 68%) was satisfied with evaluations. Proportion of satisfied trainees in the domain of hospital rotations was lowest (43%) for academic activities in the hospitals. About family medicine rotations, a higher proportion (75%) was satisfied with academic activities. Higher proportion of trainees (78-86%) was satisfied with research facilitation and supervision. Mean score for overall satisfaction was 7.63 out of 10. CONCLUSIONS: The results of this study would help focus on certain domains to improve the quality of program. We recommend family medicine programs to regularly carry out such surveys for continuous quality improvement.

An outbreak of measles in gold miners in River Nile State, Sudan, 2011.

BACKGROUND: Despite the wide use of vaccination, measles outbreaks still occur. AIMS: This study assessed cases notified during a measles outbreak in northern Sudan in 2011 and the response of the health authorities to contain the outbreak. METHODS: The records of all measles cases reported to the River Nile State health ministry in 2011 from the Abu Hamad locality, a gold-mining area, were reviewed together with the actions of the health authorities at the time of the outbreak. Seventeen gold-mining clusters were included. Data on demographic, clinical, geographic and chronological characteristics of the cases were extracted. RESULTS: The outbreak occurred from 27 January to 3 May 2011 with the peak in epidemiological week 9. A total of 445 measles cases were recorded, giving an incidence of 27.1 per 10 000 of the mining and resident population. Most cases (87.4%) were aged between 15 and 34 years. High fever was the most common symptom (99.3% of the cases), followed by conjunctivitis (80.4%); haemorrhage was recorded in 29.4%. Most cases (84.9%) were unvaccinated. Six deaths occurred (case fatality: 1.3%); two from cerebral coma and four from haemorrhagic shock. Severity of disease was significantly associated with place of origin of the cases (P = 0.003). CONCLUSION: The measles outbreak in the gold-mining areas in Abu Hamad had serious consequences attributed to poor environmental conditions, overcrowding, poor nutrition and lack of vaccination. The health authority response helped end the outbreak. The local health authority should consider the gold-mining areas as a potential risk to public health in their future plans.

An outbreak of cutaneous leishmaniasis among a displaced population in North Sudan: Review of cases.

BACKGROUND: Human cutaneous leishmaniasis (CL) is an endemic disease in many parts of Sudan. OBJECTIVE: To document an outbreak of CL among internally displaced people (IDP) in north Sudan. METHODS: A household survey was conducted in the rural region of New Manasir, at El Damer Locality in north Sudan during the year 2013. All villagers were screened for recent and old skin lesions in addition to other urgent medical problems. Written consent was obtained from each participant before data collection. A pretested, interviewer-administered questionnaire was used to collect the socio-demographic and clinical characteristics of participants. The diagnosis of CL was based on clinical findings and/or identification of the amastigotes on skin smears. RESULTS: Out of the 1,236 individuals enrolled in this survey, 688 were diagnosed as cases of CL, giving an infection rate of 55.7%. Children constituted 244 (35.5%) of infected cases. Majority of skin lesions were found in the Extremities 524 (76.2%). The average duration of skin lesions was 3.6 months (±1.6). CONCLUSION: This outbreak among IDPs affected a large proportion of inhabitants of the newly established villages in north Sudan. Preventive measures might have help control such outbreaks.

Comparison of serum lipid profile in type 2 diabetes with and without adequate diabetes control in Sudanese population in north of Sudan.

BACKGROUND: Diabetes mellitus (DM) is a major health problem in Sudan and is a leading cause of morbidity and mortality. Dyslipidemia is a major complication of diabetes and an important risk factor for cardiovascular disease (CVD). The objective of this study was to determine the prevalence of dyslipidemia and its co-relation with the glycemic control in individuals with diabetes in River Nile State, Sudan. METHODS: Individuals with diabetes attended, Naserudin Karamalla Diabetic (NKDM) Centre, in Atbara teaching hospital during study period, who volunteered to participate were included. Only those on treatment for DM for at least one year were included. Venous samples were collected for cholesterol, triglycerides, HDL, LDL, blood glucose and Glycosylated hemoglobin. Participants were interviewed using standardized pretested questionnaire to record medical history and sociodemographic characteristics. Blood pressure, body mass index (BMI) and waist circumference were measured. RESULTS: A total of 188 individuals were included. The mean age was 49.5 + 13.9 and (128) 68.1% were females. Most patients were having DM for at least 3-5 years 69 (36.7%). Poor diabetes control (HbA1c >7) was recorded in 87.2%, hypercholesterolemia, hypertriglyceridemia and high LDL were identified in 36.6%, 27.7% and 26.6% respectively. In addition, HDL was low in 61.2% of patients. CONCLUSION: Low HDL is a prominent feature in two thirds of individuals with diabetes, while high cholesterol and high triglyceride were seen in over one quarter.

Prevalence and determinants of undernutrition among children under 5-year-old in rural areas: A cross-sectional survey in North Sudan.

BACKGROUND: Child malnutrition is a major public health problem in developing countries. Therefore, the aim of this study was to estimate the prevalence of undernutrition among children <5 years in River Nile state (RNS) in North Sudan. SUBJECTS AND METHODS: A cross-sectional household survey was done in four localities in RNS. Using Multistage Cluster sampling, 1635 under 5 years' children had participated. Pretested questionnaire and anthropometric measures were used during data collection. The analysis was done using SPSS software program version 21 and World Health Organization (WHO) Anthro 2005 software. Indices were reported in z-scores and compared with the WHO 2005 reference population to determine the nutritional status of children. RESULTS: Among 1,447 surveyed children, the prevalence of stunting, underweight, and wasting were 42.5%, 32.7%, and 21%, respectively. Stunting was highest among the 48-60 months of age group (82.5%). Boys had poorer indicators of undernutrition in comparison to girls. Geographically stunting was more prevalent in Berber locality. Infectious diseases (gastroenteritis and respiratory symptoms) and incomplete vaccination were significantly associated with wasting (P = 0.007, P = 0.013, and P = 0.008). Poor socioeconomic status (P = 0.043), poorer household sanitation (P = 0.022), large family size, lack of family spacing, and infants weaned suddenly were regarded as risk factors for undernutrition. CONCLUSION: There was a high prevalence of undernutrition in the 4th and 5th year of life in RNS population, with significant gender imbalance. Our survey highlighted the importance of urgent need to improve child health in this region.

Sugar intake in Sudanese individuals was associated with some features of the metabolic syndrome: Population based study.

AIM: The aim of this study was to assess the level of sugar intake among Sudanese individuals. MATERIALS AND METHODS: A cross-sectional study with 323 participants. Respondents were grouped by the total intake of added sugars into two groups, one group with sugar intake more than 200 calories per day and other group with sugar intake less than 200 calories per day. Demographic data were collected with anthropometric measurements like body mass index (BMI) and waist circumference. Chi square, T-Tests and stepwise logistic regression were used (a p-value <0.05 was considered significant). RESULTS: High sugar intake was noted among 74.6% participants and among overweight, normal weight, followed by obese (p<0.015) and then individuals with diabetes and hypertension (p <0.000 and 0.038 respectively).High sugar intake was also associated with abdominal obesity (p<0.016), mean age of 33 years old (p<0.00) and being married and single(p<0.003). Stepwise logistic regression showed diabetes and BMI<25 were absolute predictors for sugar consumption with p value of 0.001 and 0.039 respectively. Individuals with diabetes have more than five times probability to consume large amount of sugar (Odd ratio 5.6), while those with BMI<25 have two times risk of consuming more sugar compared to those with BMI>25 group (Odd ratio 2.1). CONCLUSION: A large percentage of Sudanese population uses a high amount of sugar. High sugar intake was associated with normal weight, overweight, abdominal obesity, diabetes and hypertension. Absolute predictors of high sugar intake were diabetes and normal body weight.

Low levels of physical activity in Sudanese individuals with some features of metabolic syndrome: Population based study.

BACKGROUND: The aim of this study was to evaluate the level of physical activity among Sudanese population. METHODS: A descriptive cross sectional study composed of 323 participants from Khartoum state, Sudan. Data collected using pretested designed questionnaire based on previously validated Global Physical Activity Questionnaire. The demographic and physical measurement including blood glucose, anthropometric and blood pressure. RESULTS: The Mean age of participants was 35.5. Males were 59.9% and females 47.1% and the prevalence of inactivity was 53.8%. Despite the fact that males are more active than females (P<0.000) physical activity tends to decrease with age but this not statistically significant. Physical activity is significantly decreased with obesity, higher education and doing sedentary jobs (P<0.018, P<0.000 and P<0.000 respectively). While majority of individuals with hypertension and pre-hypertension tend to do less physical activity (P<0.045 and P<0.008 respectively). Logistic regression analysis shown that gender is absolute risk factor for physical activity. Males have more than three times probability of being physically active than women OR3.82 (1.91-7.30). In this study, physical activity was not affected by central obesity (P<0.497), diabetes (P<0.378) and being married or not (P<0.135). CONCLUSION: Physical activity in Sudanese women was significantly decreased in comparison with men.

Prevalence of tuberculosis among children in North Sudan: Are we only seeing the tip of the iceberg?

INTRODUCTION: Tuberculosis (TB) is a significant cause of morbidity and mortality among children. The vague symptoms, the uncertain diagnostic tests and lack of adequate awareness among families all contributed in masking the actual prevalence of the disease. The objective of this study was to describe the epidemiology of childhood TB in River Nile State (RNS), North Sudan. METHODS: All registered cases of TB aged 15 years and below, at the 13 management units in RNS during 3 years, 2011-2013 were included. The records included epidemiological, clinical, and microbiological data. RESULTS: Out of the 1221 total TB notified cases, children were 187 (15.3%); almost equally distributed across the 3 years of the study period. Males were 56.7%. Most of the cases (89.9%) were newly diagnosed; among them, pulmonary TB (PTB) constituted 61.5%. Sputum specimen was tested in 59.4% (111/187) of cases, and only 15.3% (17/111) of specimens were sputum smear positive for new cases. The cure rate was (76.5%), and the treatment success rate was (88.2%). The death rate was 6.1% among PTB cases and 5.6% among extra-pulmonary cases. All the 20 (10.7%) children tested for HIV were negative. CONCLUSION: TB is under-reported in RNS and treatment outcomes are sub-optimal. Strategies to identify the active case-detection among children are recommended.

Diabetes complications in Sudanese individuals with type 2 diabetes: Overlooked problems in sub-Saharan Africa?

BACKGROUND: Diabetes mellitus (DM) is a major health problem in Sudan and is a leading cause of morbidity and mortality. The objective of this study is to determine the prevalence of complications of type 2 diabetes across different cities in the country. METHODS: Individuals with type 2 diabetes, who have been on treatment for DM for at least one year and volunteered to participate, were selected from two diabetes centers in Sudan (Khartoum and Atbara). Participants were interviewed using standardized pretested questionnaire to record medical history, socio-demographic, life style characteristics and presence of complications of diabetes. RESULTS: Four hundred and twenty four individuals with T2DM were included in this study (50.7% males and 49.3% females). Good glycemic control (HbA1c <7) was found in 15.7%. Hypertension was reported in 39.9% and myocardial infarction in 5.9%, while high cholesterol and triglyceride noted in 59.9%, 32.5% respectively. Low HDL was noted in 52.6%. Other complications like peripheral neuropathy, retinopathy and diabetic foot were observed in 68.2%, 72.6% and 12.7% respectively. Factors significantly associated with these complications were longer duration of diabetes (P<0.001), and living in urban areas (P<0.004). CONCLUSION: High prevalence of complications of type 2 diabetes were observed especially in those with longer duration of diabetes and poor control.

A preliminary survey of un-diagnosed hypertension among Nubians and Coptics in Atbara and Eldamer Cities, Sudan: does ethnicity affect prevalence?

INTRODUCTION: Hypertension is a non-communicable disease of increasing importance in developing countries. Due to its silent nature and serious complications, active screening is essential in case detection. The aim of this study was to determine the prevalence of undiagnosed hypertension and to find out whether there are ethnic variations in prevalence between two Sudanese ethnicities. METHODS: This is a cross-sectional community-based study in which 100 subjects from Nuba tribe and 70 Coptics not previously known to have hypertension volunteered to participate. Blood pressure was measured and a questionnaire delineating demographic, clinical and social data was obtained from each participant. RESULTS: Female to male ratio was 2:1. The mean age was 39.5 ± 8 years for Nubians and 40.5 ± 5.5 years for Coptics. High blood pressure was detected in 48% of Nubians and 24.3% of Coptics (p>0.001). The prevalence of stage II hypertension was higher in Nubians compared to Coptics (25% vs. 3.8%; p<0.001). Besides the ethnic variation, other significant differences between the two groups were illiteracy and alcohol consumption, both of which were significantly commoner among Nubians. CONCLUSION: Undiagnosed high blood pressure is common in our local community, with some variations in prevalence and severity among different ethnic groups. Key words: Coptics; Nubians; River Nile State; Sudan; Undiagnosed hypertension.
