Our findings show that the prevalence of hypertension in Mozambique is among the highest in developing countries, both in adults and adolescents, portraying an ample margin for reduction of the morbidity and mortality burden because of high blood pressure.

This study aimed to evaluate the urinary excretion of sodium and potassium, and to estimate the main food sources of sodium in Maputo dwellers. A cross-sectional evaluation of a sample of 100 hospital workers was conducted between October 2012 and May 2013. Sodium and potassium urinary excretion was assessed in a 24-h urine sample; creatinine excretion was used to exclude unlikely urine values. Food intake in the same period of urine collection was assessed using a 24-h dietary recall. The Food Processor Plus® was used to estimate sodium intake corresponding to naturally occurring sodium and sodium added to processed foods (non-discretionary sodium). Salt added during culinary preparations (discretionary sodium) was computed as the difference between urinary sodium excretion and non-discretionary sodium. The mean (standard deviation) urinary sodium excretion was 4220 (1830) mg/day, and 92% of the participants were above the World Health Organization (WHO) recommendations. Discretionary sodium contributed 60.1% of total dietary sodium intake, followed by sodium from processed foods (29.0%) and naturally occurring sodium (10.9%). The mean (standard deviation) urinary potassium excretion was 1909 (778) mg/day, and 96% of the participants were below the WHO potassium intake recommendation. The mean (standard deviation) sodium to potassium molar ratio was 4.2 (2.4). Interventions to decrease sodium and increase potassium intake are needed in Mozambique.

Most Mozambicans were aware that high salt intake can cause health problems, but the self-reported salt intake and behaviors for its control show an ample margin for improvement. This study provides evidence to guide population level salt-reducing policies.

Objective:The ongoing demographic, nutritional and epidemiological transitions in sub-Saharan Africa highlight the importance of monitoring overweight and obesity. We aimed to assess the prevalence of overweight and obesity in Mozambique in 2014/2015 and compare the estimates with those obtained in 2005.Design:Cross-sectional study conducted in 2014/2015, following the WHO Stepwise Approach to Chronic Disease Risk Factor Surveillance (STEPS). Prevalence estimates with 95 % CI were computed for different categories of BMI and abdominal obesity, along with age-, education- and income-adjusted OR. The age-standardized prevalence in the age group 25–64 years was compared with results from a STEPS survey conducted in 2005.Setting:Mozambique.Participants:Representative sample of the population aged 18–64 years (n 2595).Results:Between 2005 and 2014/2015, the prevalence of overweight and obesity increased from 18·3 to 30·5 % (P < 0·001) in women and from 11·7 to 18·2 % (P < 0·001) in men. Abdominal obesity increased among women (from 9·4 to 20·4 %, P < 0·001), but there was no significant difference among men (1·5 v. 2·1 %, P = 0·395). In 2014/2015, the prevalence of overweight and obesity was more than twofold higher in urban areas and in women; in the age group 18–24 years, it was highest in urban women and lowest in rural men.Conclusions:In Mozambique, there was a steep increase in the prevalence of overweight and obesity among adults between 2005 and 2014/2015. Overweight and obesity are more prevalent in urban areas and among women, already affecting one in five urban women aged 18–24 years.

Objective:To assess the Na content and price of bread available in bakeries in the city of Maputo in 2018 and describe trends since 2012.Design:Cross-sectional evaluation of bread sold in twenty bakeries in the city of Maputo. Three loaves of white and three loaves of brown bread were collected from each bakery when available, and Na contents were quantified by flame photometry. To assess trends, samples of white bread collected in 2012 and analysed using the same methodology were compared with samples of white bread collected in 2018 from the same bakeries.Setting:City of Maputo, capital of Mozambique.Results:In 2018, the mean (range) Na content in mg/100 g of white and brown breads were 419·1 (325·4–538·8) and 389·8 (248·0–609·0), respectively. Non-compliance with Na targets in bread according to the South African regulation (<380 mg/100 g) was observed in 70 % of white and 43 % of brown bread samples. A total of twelve bakeries had samples evaluated in both 2012 and 2018; among these, the mean Na content in white bread decreased by just over 10 % – the mean difference (95 % CI) was 46·6 mg/100 g (1·7, 91·5); and there was a significant increase of 3·7–5·4 meticais in the mean price per 100 g of white bread.Conclusions:The Na content of bread available in bakeries in the city of Maputo decreased in recent years despite the absence of a specific regulation in Mozambique.

Aims The relationship between N‐terminal pro‐brain natriuretic peptide (NT‐pro‐BNP) and galectin‐3 and outcomes has not been studied in African patients with acute heart failure (AHF). The current analysis sought to describe the association between plasma levels of NT‐pro‐BNP and galectin‐3 and cardiovascular (CV) death or heart failure (HF) hospitalization, as well as their associations with symptoms and echocardiography markers of left and right ventricular remodelling among AHF patientsv in sub‐Saharan Africa. Methods and results In a subset of 80 patients with complete data in a study assessing the effects of hydralazine and nitrates in patients with AHF (BAHEF trial; NCT01822808), NT‐pro‐BNP and galectin‐3 analyses were performed, and the association with various characteristics and outcome measures assessed. The mean age of the patients for whom the aforementioned biomarkers were measured was 52.6 years, with 52.5% women. Galectin‐3 at baseline predicted changes (Week 24 to baseline) in left ventricular ejection fraction, left ventricular end‐systolic diameter, left ventricular end‐diastolic diameter, and tricuspid annular plane systolic excursion. Biomarkers and their changes were not associated with changes in 6 min walk test at 24 weeks. Baseline galectin‐3 and change in NT‐pro‐BNP were associated with improvements in dyspnoea at 24 weeks. Nine patients had an HF readmission or died of CV causes through 24 weeks (11.6%). Both biomarkers at baseline predicted combined CV death or HF hospitalization through Week 24 (P‐values = 0.0328 and 0.0001, respectively). Conclusions In a cohort of patients with AHF from sub‐Saharan Africa, NT‐pro‐BNP and galectin‐3 at baseline and their changes were associated with some changes in dyspnoea, echocardiographic remodelling, and CV death or HF hospitalization through Week 24. These tests have potential of being used for risk stratification of AHF patients in sub‐Saharan Africa where resources are scarce.
