Lipid disorders among Black Africans non-users of lipid-lowering medication.

Objective: Angola is a sub-Saharan African country where the population has scarce access to lipidlowering medication. We sought to determine the frequency of lipid disorders among Angolan nonusers of lipid-lowering medication.

Material And Methods: A cross-sectional descriptive study was carried out in a sample of 604 workers from the public sector.

Cardiovascular risk factors in pre-pubertal schoolchildren in Angola.

Methods: The incidence of obesity is increasing worldwide, especially in countries with accelerated economic growth. We determined the prevalence of and associations between overweight/obesity and cardiovascular risk factors in pre-pubertal (seven- to 11-year-old) schoolchildren (both genders, n = 198) in Luanda, Angola. Biochemical (fasting blood) and clinical examinations were obtained in a single visit.

Gender-specific determinants of blood pressure elevation in Angolan adults.

Background: Hypertension affects African-American adults more than any other ethnic group in the US. However, some of the black populations living outside Africa are well adapted to food and lifestyle. We aimed to describe the clinical characteristics underlying the gender-specific determinants of BP and the risk of hypertension in public-sector workers living in Angola.

Predictors and Reference Values of Pulse Wave Velocity in Prepubertal Angolan Children.

Carotid-femoral pulse wave velocity (PWV) has been used as the gold standard method to estimate arterial stiffness. However, its use in clinical practice is still limited because reference values for specific groups, such as black children, remain unknown. The authors aimed to investigate predictors and to propose preliminary reference values of PWV in this population.

Knowledge, attitude and behaviour regarding dietary salt intake among medical students in Angola.

Background: Levels of salt consumption and its awareness among medical students in Angola remain insufficiently studied. This study determined salt intake and assessed medical students' knowledge, attitude and behaviour regarding salt consumption.

Methods: Were collected 24-hour urine samples from a random sample of 123 undergraduate medical students aged 17-43 years who were studying at the University of Agostinho Neto in Luanda.

Prevalence of cardiovascular risk factors and socioeconomic level among public-sector workers in Angola.

Background: Cardiovascular diseases are the leading cause of death in the majority of developed and developing countries. African countries are currently facing an increase in both cardiovascular and transmitted diseases. In addition, cardiovascular risk varies among different socioeconomic groups.

Age- and gender-specific reference values of pulse wave velocity for African adults: preliminary results.

Pulse wave velocity (PWV) is an independent predictor of cardiovascular (CV) risk. Higher PWV values have been observed in Africans; however, there are no established age- and gender-adjusted reference values for this population. Therefore, PWV was measured using a validated device (Complior SP) in 544 subjects recruited from an occupational cohort of employees of a public university in Angola.

Arterial stiffness in lower limb amputees.

Background: A high carotid-femoral pulse wave velocity (PWV) has been related to increased cardiovascular morbidity and mortality, but has not been previously evaluated in amputees. The aim of this study was to compare PWV between amputees and nonamputees.

Methods: In this cross-sectional study, data were collected from 60 male lower limb amputees and 86 male age-matched nonamputees.

Correlation between the creatinine clearance in the urine collected during 24 hours and 12 hours.

Introduction: Creatinine concentration in plasma has been used to evaluate renal function. However, the endogenous creatinine clearance (CrCl) is more sensitive to this goal.

Objective: Correlate the CrCl calculated from urinary collects of 12 h and 24 h.
