    This cross-sectional study is aimed at assessing sodium (Na) and potassium (K) content and the molar Na:K ratios of the most commonly available ready-to-eat street foods in Tajikistan and Kyrgyzstan. Four different samples of each of these foods were collected and 62 food categories were evaluated through bromatological analysis. Flame photometry was used to quantify sodium and potassium concentrations. The results show that home-made foods can be important sources of sodium. In particular, main dishes and sandwiches, respectively, contain more than 1400 and nearly 1000 mg Na in an average serving and provide approximately 70% and 50% of the maximum daily recommended values. Wide ranges of sodium content were found between individual samples of the same home-made food collected from different vending sites from both countries. In industrial foods, sodium contents ranged from 1 to 1511 mg/serving in Tajikistan, and from 19 to 658 mg/serving in Kyrgyzstan. Most Na:K ratios exceeded the recommended level of 1.0 and the highest ratios were found in home-made snacks (21.2) from Tajikistan and industrial beverages (16.4) from Kyrgyzstan. These findings not only improve data on the nutritional composition of foods in these countries, but may also serve as baseline information for future policies and interventions. View Full-Tex

    BACKGROUND: Control of hypertension in low- and middle-income countries (LMICs) is poor, often less than 10%. A strong body of evidence demonstrates that home blood pressure management lowers blood pressure, and recent guidelines from the National Institute for Clinical Health and Excellence recommends home blood pressure monitoring. However, the preponderance of data on the benefits of home blood pressure management comes from studies in high-income countries. OBJECTIVE: The objective of the study is to examine whether an intervention of home blood pressure management is feasible in LMICs. Home blood pressure management is defined as self-monitoring of blood pressure and self-titration of antihypertensive medications. We will identify barriers and facilitators of home blood pressure management and explore unique contextual factors in LMICs that influence implementation of home blood pressure management. METHODS: Participants will be recruited from 6 sites from 2015 to 2018. Patients and health care workers will be included. We will use mixed methods including focus groups, interviews, and standardized checklists. When possible, we will adapt materials from prior successful studies so that they are culturally and contextually appropriate. RESULTS: This ongoing study is funded by the World Heart Federation. The information that is obtained will be used to develop a randomized clinical trial of home blood pressure management in LMICs. CONCLUSIONS: The data generated from this qualitative study will provide much needed information from patients and health care workers about barriers and facilitators of home blood pressure management and unique contextual factors that might influence implementation of home blood pressure management in LMICs

    Differences in socio-demographic and risk factor profile, clinical presentation, and outcomes between patients with and without RHD heart failure in Sub-Saharan Africa: results from the THESUS-HF registry

    Background: Rheumatic heart disease (RHD) was found in the THESUS-HF registry to be the third most common cause of acute heart failure (AHF) in Sub-Saharan Africa. Methods: One thousand six patients with AHF from 9 Sub-Saharan African countries were recruited in THESUS-HF, of which 143 (14.3%) had RHD-AHF. Clinical characteristics and outcomes in patients with RHD-AHF and non-RHD-AHF were compared. Kaplan-Meier plots for time to all-cause death and/or HF readmission according to the presence of RHD-AHF and non-RHD-AHF were performed and survival distributions compared using the log-rank test. Cox regression was used to determine the hazard ratio of death to day 180 and death or readmission to day 60 after adjusting for confounders. Results: Patients with RHD-AHF were younger, more often females, had higher rates of atrial fibrillation, had less hypertension, hyperlipidemia and diabetes, had lower BP, and higher pulse rate and better kidney function and echocardiographic higher ejection fraction larger left atria and more diastolic dysfunction. Patients with RHD-AHF had a numerically longer mean stay in the hospital (10.5 vs. 8.8 days) and significantly higher initial hospitalization mortality (9.1% vs. 3.4%). Conclusions: In conclusion, patients with HF related to RHD were younger, have higher rate of atrial fibrillation and have a worse short-term outcome compared to HF related to other etiologies in Sub-Saharan Afric

    Regional differences in the daily consumption of smoked and smokeless tobacco among adults (25-64 years) in Mozambique: 2005 versus 2014/2015

    Within-country differences in the prevalence of tobacco consumption may be expected in Mozambique, as determinants of tobacco use vary considerably countrywide. We compared the daily use of smoked and smokeless tobacco in 2005 and 2014/2015 across Mozambican regions. Two surveys were conducted in Mozambique, in 2005 and 2014/2015, with representative samples of the adult population, following the World Health Organization’s STEPwise Approach to NCD Risk Factor Surveillance. Prevalence estimates were computed for daily use of different types of tobacco, stratified by regions. Data from the 2014/2015 survey were compared to those from the 2005 survey, after direct age-standardization. During the 10-year period, a significant reduction was observed in the prevalence of daily tobacco smoking among women in the Northern and men in the Southern provinces, due to the decrease in the consumption of hand-rolled cigarettes among Northern women (from 9.6% to 2.3%), and manufactured cigarettes among Southern men (from 23.7% to 11.8%). In Center and Northern regions, nonsignificant increases were observed in the consumption of manufactured cigarettes among men. The consumption of smokeless tobacco among Southern women decreased (from 3.1% to 1%). There was a decrease in the daily consumption of hand-rolled cigarettes among women in the North and of manufactured cigarettes among men in the South, as well as a potential trend towards residual smokeless tobacco consumption. However, the results suggest increases in the daily consumption of manufactured cigarettes among men in the Center and Northern regions

    The causes, treatment, and outcome of acute heart failure in 1006 Africans From 9 countries

    Get PDF
    Background: Acute heart failure (AHF) in sub-Saharan Africa has not been well characterized. Therefore,wesought to describe the characteristics, treatment, and outcomes of patients admitted with AHF in sub-Saharan Africa. Methods: The Sub-Saharan Africa Survey of Heart Failure (THESUS–HF) was a prospective, multicenter, observational survey of patients with AHF admitted to 12 university hospitals in 9 countries. Among patients presenting with AHF, we determined the causes, treatment, and outcomes during 6 months of follow-up. Results: From July 1, 2007, to June 30, 2010, we enrolled 1006 patients presenting with AHF. Mean (SD) age was 52.3 (18.3) years, 511 (50.8%) were women, and the predominant race was black African (984 of 999 [98.5%]). Mean (SD) left ventricular ejection fraction was 39.5% (16.5%)... Conclusions: In African patients, AHF has a predominantly nonischemic cause, most commonly hypertension. The condition occurs in middle-aged adults, equally in men and women, and is associated with high mortality. The outcome is similar to that observed in non- African AHF registries, suggesting that AHF has a dire prognosis globally, regardless of the cause

    Corrigendum: Front Nutr. 2022 Aug 19;9:1005673. doi: 10.3389/fnut.2022.1005673. eCollection 2022FeedCities ProjectStreet food makes a significant contribution to the diet of many dwellers in low- and middle-income countries and its trade is a well-developed activity in the central Asian region. However, data on its purchase and nutritional value is still scarce. This study aimed to describe street food purchasing patterns in central Asia, according to time and place of purchase. A multicentre cross-sectional study was conducted in 2016/2017 in the main urban areas of four central Asian countries: Dushanbe (Tajikistan), Bishkek (Kyrgyzstan), Ashgabat (Turkmenistan) and Almaty (Kazakhstan). Street food markets (n = 34) and vending sites (n = 390) were selected by random and systematic sampling procedures. Data on the purchased foods and beverages were collected by direct observation. Time and geographic location of the purchases was registered, and their nutritional composition was estimated. A total of 714 customers, who bought 852 foods, were observed. Customers’ influx, buying rate and purchase of industrial food were higher in city centers compared to the outskirts (median: 4.0 vs. 2.0 customers/10min, p < 0.001; 5.0 vs. 2.0 food items/10min, p < 0.001; 36.2 vs. 28.7%, p = 0.004). Tea, coffee, bread and savory pastries were most frequently purchased in the early morning, bread, main dishes and savory pastries during lunchtime, and industrial products in the mid-morning and mid-afternoon periods. Energy and macronutrient density was highest at 11:00–12:00 and lowest at 09:00–10:00. Purchases were smaller but more energy-dense in city centers, and higher in saturated and trans-fat in the peripheries. This work provides an overview of the street food buying habits in these cities, which in turn reflect local food culture. These findings from the main urban areas of four low- and middle-income countries which are currently under nutrition transition can be useful when designing public health interventions customized to the specificities of these food environments and their customers.This work was supported by the World Health Organization Europe (WHO registration 2015/591370-0 and 2017/698514) and by the Ministry of Health of the Russian Federation.

    Projected burden and distribution of elevated blood pressure levels and its consequence among adolescents in sub-Saharan Africa

    Get PDF
    Background: There is minimal data on the number of adolescents in sub-Saharan Africa (SSA) with elevated blood pressure (BP) at increased risk of future cardiovascular events. Combining country-specific population data with data derived from two previously conducted meta-analyses (one African-specific, one based on international cohorts), we sought to address this knowledge deficit. Methods: We used meta-analysis data from 37 926 adolescents participating in 36 contemporary SSA studies to generate sex-specific proportions of adolescents aged 10–14 and 15–19 years with elevated BP. The estimates were applied to the 2021 World Bank population data for each country in SSA. We then applied the rate of cardiovascular events attributable to elevated BP levels, derived from a meta-analysis of 17 observational, longitudinal cohort studies comprising 4.5 million young adults (non-African), to determine the excess number of cardiovascular events linked to hypertension among those aged 15–19 years transitioning to adulthood. Results: The estimated prevalence of elevated BP among male and female adolescents aged 10–14 years living in SSA was 7.2% (95% confidence interval (CI) = 4.9–9.9) and 6.9% (95% CI = 4.7–9.5), respectively, which increased to 13.0% (95% CI = 10.6–15.6) and 12.5% (95% CI = 10.4–15.3) among male and female adolescents aged 15–19 years, respectively. Consequently, we estimate that 13.6/138.0 million (95% CI = 10.4–17.3) male and 12.9/135.7 million (95% CI = 9.83–16.3) female adolescents living in SSA have elevated BP. Among the estimated 16.1 million adolescents aged 15–19 years with elevated BP approaching adulthood, the projected excess in cardiovascular events attributable to hypertension (vs normotension) is 201 000 (95% CI = 115 000–322 000) to 503 000 (95% CI = 286 000–805 000) over the next 10–25 years. Conclusions: Based on the best available data, we estimate that 26.5 million adolescents living in SSA have elevated BP. If left undetected and untreated among those approaching adulthood (those aged 15–19 years), they will experience >0.5 million excess cardiovascular events associated with persistently elevated BP within the next 25 years

    Gender differences in clinical characteristics and outcome of acute heart failure in sub-Saharan Africa: results of the THESUS-HF study

    Get PDF
    Background: The impact of gender on the clinical characteristics, risk factors, co-morbidities, etiology, treatment and outcome of acute heart failure in sub-Saharan Africa has not been described before. The aim of this study was to evaluate the sex diffe rences in acute heart failure in sub-Saharan Africa using the data from The sub-Saharan Africa Survey of Heart Failure (THESUS-HF). Methods and results: 1,006 subjects were recruited into this prospective multicenter, international observational heart failure survey. The mean age of total population was 52.4 years (54.0 years for men and 50.7 years for women). The men were significantly older (p = 0.0045). Men also presented in poorer NYHA functional class (III and IV), p = 0.0364). Cigarette smoking and high blood pressure were significantly commoner in men (17.3 vs. 2.6 % and 60.0 vs. 51.0 % respectively). On the other hand, atrial fibrillation and valvular heart disease were significantly more frequent in women. The mean hemoglobin concentration was lower in women compared to men (11.7 vs. 12.6 g/dl, p ≤ 0.0001), while the blood urea and creatinine levels were higher in men (p \u3c 0.0001). LV systolic dysfunctional was also seen more in men. Men also had higher E/A ratio indicating higher LV filling pressure. Outcomes were similar in both sexes. Conclusions: Although the outcome of patients admitted for AHF in sub-Saharan regions is similar in men and women, some gender differences are apparent suggesting that in men more emphasis should be put on modifiable life risk factors, while in women prevention of rheumatic heart diseases and improved nutrition should be addressed vigorously

    This article belongs to the Special Issue Food Security, Food Intake and Eating Behaviour in Low- and Middle- Income CountriesThis study aimed to describe street food purchases in cities from Central Asia, considering customers’ characteristics and the nutritional composition of the foods and beverages. Cross-sectional studies were conducted in 2016/2017 in Dushanbe (Tajikistan), Bishkek (Kyrgyzstan), Ashgabat (Turkmenistan) and Almaty (Kazakhstan). Direct observation was used to collect data on the purchases made by street food customers, selected by random and systematic sampling. Nutritional composition was estimated using data from chemical analyses, food composition tables or food labels. A total of 714 customers (56.6% females, 55.5% aged ≥35 years, 23.3% overweight/obese) were observed, who bought 852 foods and beverages, the most frequent being savoury pastries/snacks (23.2%), main dishes (19.0%), sweet pastries/confectionery (17.9%), tea/coffee (11.3%) and soft drinks/juices (9.8%). Fruit was the least purchased food (1.1%). Nearly one-third of customers purchased industrial food items (31.9%). The median energy content of a street food purchase was 529 kcal/serving. Saturated and trans-fat median contents were 4.7 g/serving and 0.36 g/serving (21.4% and 16.5% of maximum daily intake recommendations, respectively). Median sodium and potassium contents were 745 mg/serving (37.3% of maximum recommendation) and 304 mg/serving (8.7% of minimum recommendation), respectively. In general, the purchases observed presented high contents of energy, saturated-fat, trans-fat and sodium, and low levels of potassium. Policies towards the improvement of these urban food environments should be encouraged.The FEEDCities project is funded by the World Health Organization Europe (WHO registration 2015/591370-0 and 2017/698514) and by the Ministry of Health of the Russian Federation.
