RESUMO
BACKGROUND: Anthropometric measurements can easily reflect any changes in the lipid concentration in the human body. OBJECTIVES: The present work is aimed at studying lipid profile and its relation to anthropometric measurements in college males from Riyadh, Saudi Arabia. SUBJECTS AND METHODS: This study was conducted from September 2006 to December 2008. 333 students aged 18-35 years of Riyadh College of Health Science - male section - participated in the study. Anthropometric measurements including weight, height, waist and hip circumferences were measured. Body Mass Index (BMI) was calculated. Fasting blood sugar and lipid profile including total cholesterol (TC), Low density lipoprotein cholesterol (LDL), high density lipoprotein cholesterol (HDL) and triglycerides (TG) were estimated. Socio-demographic data were collected from a questionnaire. RESULTS: Mean TC level was 4.227 ± 0.869 mmol/l, while for LDL, HDL and TG were 2.57 ± 0.724, 1.360 ± 0.545 and 1.385 ± 0.731 mmol/l, respectively. Mean TC level did not differ significantly across weight groups except among obese patients. Mean HDL, LDL and TG did not differ significantly among different groups at 5% level of significance. There was positive, statistically non-significant correlation between age and BMI. The correlation between age and all lipid parameters were statistically non-significant. There was positive correlation between BMI and TC and LDL, while there was a negative correlation between BMI and HDL. There was no correlation between BMI and triglycerides. CONCLUSION: BMI, waist and hip circumferences all increase with age. The level of TC, LDL and TG go high with increase in age and BMI.
RESUMO
We followed 565 male patients with non-Hodgkin's lymphoma (NHL) in two hospitals of Saudi Arabia. We investigated these cases for presence of hepatitis B virus (HBV) and hepatitis C virus (HCV) by determining the HBsAg and anti-HCV. Anti-HCV positive cases were confirmed by PCR. The NHL cases were classified on the basis of working formulation. The results of HBV and HCV in cases of NHL were compared with the prevalence of these viruses in healthy male blood donors. We found 11.2% of cases of NHL were positive for HBV and 16.1% for HCV, compared to 3.4% HBV and 2.9% HCV among blood donors. The highest numbers of cases (48.4% of HBV and 56% of HCV) were seen in the intermediate and low grade of NHL, respectively. Follicular small cleaved was the predominant type in both types of infection. The variation in prevalence of HBV and HCV in NHL from that of the general population was statistically significant (p<0.001). We observed that the background prevalence of HBV definitely affects the rate of infection in NHL, while infection of HCV in cases of NHL is independent of its background prevalence.
