To determine normal values of respiratory function for Sudanese, a randomized stratified crosssectional study was performed on 2250 healthy Sudanese aged 7-86 years in 2002-05. Data were obtained through a questionnaire, pulmonary function testing and taking anthropometric measurements. Lung function and anthropometric measurements were correlated and regression equations were derived. Sudanese of Arab ethnic background had significantly higher forced vital capacity (FVC), forced expiratory volume in 1 (first) second (FEV1) and peak expiratory flow rate (PEFR) than those of African ethnicity. In adults a positive correlation was found between lung function and height and a negative correlation with age. Gender and ethnic variations in Sudanese lung function were confirmed. Comparisons were made with data from other international studies. These values can be used as reference values in respiratory clinics in Sudan. 1Faculty of Medicine, Imam Elmahdi University, Kosti, Sudan (Correspondence to A.A. Bashir: amirali69@yahoo.com

Ideal body weight with proper physical activity and good sleep are essential parameters for good quality of life. This study is concerned with assessing the association of general obesity, physical activity and sleeping hours with hemoglobin (Hb) concentration and red blood cell (RBC) parameters in healthy adults in Sudan. In this cross sectional study, 1086 healthy adults between 20 and 60 years were included out of which 275 were males and 811 were females. A complete blood count (CBC) was performed for Hb, RBC count, PCV, MCH and MCHC using Sysmex KX-21 automated hematology analyzer. The median and 95 percentile (2.5th to 97.5th) range values for Hb and RBC count in underweight were 13.0 (Range: 9.6-16.7) g/dl and 4.6 (Range: 3.6-5.8) ×1000/µL respectively, while Hb and RBC count in obese were 13.1 (Range: 10.4-17.0) g/dl and 4.6 (Range: 3.7-5.9) ×1000/µL respectively, with no significant difference. The RBC count (p=0.004) and Hb (p≤0.001) were significantly high in physically active compared to physically inactive participants; whereas the hemoglobin concentration (p=0.047), red blood cells (p=0.007) and hematocrit (p≤0.001) values were significantly low in long-term sleep compared to normal sleeping hours. In conclusion, there were no significant differences in hemoglobin concentration, RBC count, PCV, MCH and MCHC between under weight, normal weight, overweight and obese persons. Increased physical activity was associated with higher Hb levels and RBC counts, while long-term sleep showed lower Hb and RBCs.

Background: Diabetes mellitus and thyroid diseases are the most prevalent metabolic disorders in Sudan. The value of HbA1C reflects the glycemic status over the last 2-3 months. So, in this study, an insight for thyroid hormone regulation of glucose metabolism is investigated. Is to study the association between thyroid hormones levels, fasting blood sugar (FBS) and HbA1c in healthy adults.Methods: A cross sectional study was performed in a healthy Sudanese cohort in the period between September 2017 to November 2018, involving 610 healthy adult Sudanese aged 20 to 60 years. HbA1c, fasting blood sugar (FBS), T3, T4 and TSH were measured.Results: The study results demonstrated a significant association between the median concentration of T3 and T4 with plasma level of HbA1c. A significant linear correlation between serum concentration of T3 and fasting blood sugar (FBS) was observed. Inverse correlation was detected between serum TSH and HbA1c, FBS in study population.Conclusions: The present study concluded that FBS and HbA1c levels were increased with increasing of both T3 and T4. Based on this study all the thyroid patients’ especially hyperthyroid patients should have regular checkup of their glucose levels.

Introduction: Blood pressure is one of the most often measured clinical parameters, and assessment of blood pressure has a considerable impact on diagnostic decisions. Objectives: To establish blood pressure normal reference values in Sudanese. Methods: A cross-sectional study was conducted from September 2016 to November 2018. Eight hundred eighty-eight healthy adult Sudanese between the ages of 18 and 60 (203 men and 685 women) were randomly selected from the states of Khartoum, Northern, Gezira, Red Sea, and North Darfur. Clinical, anthropometric, and blood pressure measurement data were collected. Results: The mean for all volunteers was 113.93 ± 9.917 mmHg, systolic blood pressure (SBP) and 75.29 ± 6.79 mmHg, diastolic blood pressure (DBP). SBP in men was 118.6 + 7.642 mmHg compared to 112.53 + 9.121 mmHg in women, while DBP in men was 77.51 + 5.984 mmHg compared to 74.63 + 6.844 mmHg in women. Beside the gender variations, blood pressure values also showed geographical variability. There was a positive connection between blood pressures (SBP and DBP), BMI, and age. (P < 0.05) was used for significance. Conclusion: Blood pressure of Sudanese was found to be within the normal international range with gender and geographical variability. It showed positive correlation with age and BMI.
