Summary 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. Their knowledge, attitude and behaviour regarding dietary salt were surveyed. Socio-demographic, clinical and anthropometric data were collected. Results Average salt intake was 14.2 ± 5.1 g/day, without significant difference between genders (p = 0.221). In total, 96.7% consumed over 5 g/day, but only 6.5% of participants were aware of their excessive salt intake. The majority knew about salt-related health consequences and 45.5% reported they controlled their salt intake. Conclusions This study indicated a high salt intake and inadequate behaviour regarding dietary salt consumption among medical students studying at the University of Agostinho Neto. This highlights the need for nutritional education to improve their dietary habits and future role in counselling.

BACKGROUND To analyze the relationship between early-life indicators, blood pressure (BP), and arterial stiffness in childhood, in three samples with different bio-cultural characteristics. METHODS The total sample included 520 schoolchildren 9–10 years of age from Madrid (Spain), Vitória (Brazil), and Luanda (Angola). Height and weight, BP, and carotid-femoral pulse wave velocity (cf-PWV) were measured, all by one observer in each site, and body mass index (BMI) was calculated. Birth weight, gestational age, type of feeding, and age at weaning were extracted from official health cards. Data were analyzed by multiple linear regression models. RESULTS No significant differences were observed in systolic blood pressure (SBP) and diastolic blood pressure (DBP) among the samples (P = 0.107 and P = 0.808). Luanda showed the higher cf-PWV (5.7 m/s), followed by Vitória (5.3 m/s) and Madrid (4.9 m/s; P < 0.001). Explanatory factors for the observed variability in SBP, DBP, and cf-PWV, obtained by means of multiple linear regression models, were different in three samples. BMI showed a positive and significant association with SBP, DBP, and cf-PWV in three samples. In the Angolan sample, in addition to BMI, birth weight was maintained in the explanatory models of SBP and cf-PWV adjusted for BP, with a negative and significant coefficient (−0.019 and −0.019) CONCLUSIONS Higher values of BMI in childhood are related with higher values of cf-PWV, SBP, and DBP in the three samples. Children from Angola showed the highest mean value of cf-PWV, especially those who had lower birth weight, suggesting that worse conditions in fetal life may contribute to increased aortic stiffness in childhood.

- Abstract
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. Prepubertal schoolchildren (N=157; mean age, 9.36±1.41 year) from Luanda (Angola) with normal blood pressure values and without obesity were included. Mean PWV was 5.73±0.68 m/s, with no difference between the sexes. Univariate regression analysis showed a significant (P<.05) positive correlation between PWV and height, age, body weight, lean body weight, and blood pressure. In multivariate analysis, however, only height remained an independent predictor of PWV [PWV=0.018×height (cm)+3.230]. Curves of PWV percentiles as a function of height are proposed, thus identifying normal PWV in black children. [ABSTRACT FROM AUTHOR]

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. Thus, we determined the prevalence of modifiable cardiovascular risk factors in apparently healthy public-sector workers and investigated possible relationships with socioeconomic status. Methods: We employed a cross-sectional study comprising 42.2% (n = 615) of the public-sector workers at Agostinho Neto University, 48% (n = 294) male and 52% (n= 321) female, with ages between 20 and 72 years and from various socioeconomic groups. The study was conducted from February 2009 to December 2010. Personal, anthropometric, biochemical, hemodynamic, socioeconomic, and physical activity data were collected. Results: The prevalence rates of cardiovascular risk factors were as follows: hypertension, 45.2% (men 46.3%, women 44.2%, P > 0.05); hypercholesterolemia, 11.1% (men 10.5%, women 11.5%, P > 0.05); low high-density lipoprotein (HDL) cholesterol, 50.1% (men 36.9%, women 62.3%; P < 0.05); hypertriglyceridemia, 10.6% (men 12.6%, women 8.7%, P > 0.05); smoking, 7.2% (men 10.2%, women 4.4%; P < 0.05); diabetes, 5.7% (men 5.5%, women 5.9%, P > 0.05); overweight, 29.3% (men 27.3%, women 31.2%, P > 0.05); obesity, 19.6% (men 9.2%, women 29.0%; P < 0.05); sedentary lifestyle, 87.2% (men 83.0%, women 91,0%, P < 0.05); and left ventricular hypertrophy, 20% (men 32.0%, women 9.0%; P < 0.05). At least one risk factor was present in 27.7% of the sample; 15.2% had two risk factors, and 31.4% had three or more risk factors. Among the individuals with low socioeconomic status, 41.0% had three or more risk factors. Conclusions: The results of this study suggest the existence of a high prevalence of multiple risk factors for cardiovascular disease in apparently healthy public-sector workers in Angola. The workers in lower socioeconomic groups had higher incidences of hypertension, smoking, and left ventricular hypertrophy. [ABSTRACT FROM AUTHOR]

Abstract: Aims: The aim of this study was to compare esophageal motor characteristics between diabetics and healthy individuals. Methods: Esophageal manometry was performed in 34 type 2 diabetics and 32 healthy individuals. Waves were evaluated in the 3 thirds of the esophagus (P1=upper, P2=middle, and P3=distal). Results: In diabetics vs. controls, wave distribution was as follows: peristaltic waves, 83.5±22.2% vs. 96.3±4.4%, p <0.002; simultaneous waves, 3.26±5.8% vs. 0.53±1.3%, p <0.01; no transmitted waves, 10.62±20.7% vs. 2.75±3.0%, p <0.002; and retrograde waves, 2.68±4.0% vs. 0.31±1.1%, p <0.03. Wave amplitude was similar between groups. Average upstroke (mmHg/s) in diabetics vs. non-diabetics was P2, 33.8±13.9 vs. 40.2±17.7, p <0.03; and P3, 29.8±15.3 vs. 41.3±14.0, p <0.002. Conclusions: (1) Simultaneous waves, no transmitted waves, and retrograde esophageal waves were significantly more frequent in diabetics. (2) Average upstroke was significantly lower within the middle and distal esophagus of diabetic individuals. (3) Wave amplitude was similar in both groups. [Copyright &y& Elsevier]

- Abstract
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. PWV was measured noninvasively using a Complior(®) device. All participants underwent laboratory investigations and anthropometry. The difference in PWV between amputee and nonamputees was estimated. Multivariate regression was used to adjust for differences between the groups as a result of potential confounders., Results: PWV was higher in amputees than in nonamputees (10.8 ± 1.9 m/sec versus 9.9 ± 1.8 m/sec, P = 0.008, respectively). This difference remained even after adjusting for confounding factors., Conclusion: A higher PWV was demonstrated in lower limb amputees. Routine assessment of PWV may contribute to cardiovascular risk stratification in amputees.
