Abstract
BACKGROUND The dietary factors associated with the high burden of hypertension among indigenous Africans remain poorly understood. We assessed the relationship between dietary patterns and hypertension among indigenous Africans. METHOD In this study, 1550 participants with hypertension matched (for age: ± 5 years, sex and ethnicity) with 1550 participants without hypertension were identified from the stroke-free population in the Stroke Investigative Research and Educational Network study in Ghana and Nigeria. Food consumption was assessed using a food frequency questionnaire, and dietary information was summarized using principal component analysis to identify seven dietary patterns. Conditional logistic regression was applied to compute the odds ratio (OR) and 95% confidence interval (CI) for the risk of hypertension by tertiles of dietary patterns adjusting for age, education, income, smoking, alcohol use, physical inactivity, family history of cardiovascular diseases, obesity and salt intake at a two-sided P less than 0.05. RESULTS Multivariable-adjusted OR [95% confidence interval (CI)] for risk of hypertension by second and third tertiles [using the lowest (first) tertile as reference] of dietary patterns were 0.62 (0.48-0.80), 0.70 (0.54-0.90) for whole grains and fruit drinks; 0.87 (0.68-1.12), 0.83 (0.64-1.08) for fruits; 0.85 (0.65-1.10), 0.97 (0.75-1.26) for vegetables, legumes and potatoes; 0.78 (0.60-1.00), 0.84 (0.65-1.08) for fried foods and sweetened drinks; 1.13 (0.88-1.45), 0.80 (0.62-1.03) for poultry product and organ meat; 1.11 (0.86-1.43), 0.88 (0.68-1.14) for red meat; and 1.14 (0.88-1.48), 1.09 (0.84-1.43) for processed foods ( P < 0.05). CONCLUSION A higher adherence to dietary consumption of whole grains and fruits was inversely associated with low odds of hypertension in this population.

J Hum Hypertens 2024; 38:352-364. [PMID: 35430612 PMCID: PMC11001577 DOI: 10.1038/s41371-022-00688-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Revised: 02/16/2022] [Accepted: 03/30/2022] [Indexed: 12/16/2022]
Abstract
Urbanisation is considered a major contributor to the rising prevalence of hypertension in West Africa, yet the evidence regarding rural-urban differences in the prevalence of hypertension in the region has been mixed. A systematic literature search of four electronic databases: PubMed, Embase, African Journals Online, and WHO's African Index Medicus; and reference lists of eligible studies was carried out. Original quantitative studies describing the rural-urban difference in the prevalence of hypertension in one or more countries in West Africa, and published in English language from the year 2000 to 2021 were included. A random effects meta-analysis model was used to estimate the odds ratio of hypertension in rural compared to urban locations. A limited sex-based random effects meta-analysis was conducted with 16 studies that provided sex-disaggregated data. Of the 377 studies screened, 22 met the inclusion criteria (n = 62,907). The prevalence of hypertension was high in both rural, and urban areas, ranging from 9.7% to 60% in the rural areas with a pooled prevalence of 27.4%; and 15.5% to 59.2% in the urban areas with a pooled prevalence of 33.9%. The odd of hypertension were lower in rural compared to urban dwellers [OR 0.74, 95% CI: 0.66-0.83; p < 0.001]. The pooled prevalence of hypertension was 32.6% in males, and 30.0% in females, with no significant difference in the odds of hypertension between the sexes [OR 0.91, 95% CI: 0.8-1.05, p = 0.196]. Comprehensive hypertension control policies are needed for both rural, and urban areas in West Africa, and for both sexes.

Estimation of 24-hour urinary sodium and potassium excretion among Chinese adults: a cross-sectional study from the China National Nutrition Survey. Am J Clin Nutr 2024; 119:164-173. [PMID: 38176776 DOI: 10.1016/j.ajcnut.2023.09.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 09/01/2023] [Accepted: 09/12/2023] [Indexed: 01/06/2024] Open
Abstract
BACKGROUND High-sodium intake is one of the most important risk factors for hypertension and cardiovascular disease, yet reliable national estimates of sodium intake in Chinese adults have not been reported. OBJECTIVES We estimated 24-h urinary sodium and potassium excretion and population daily sodium and potassium intake of Chinese adults for the first time at a national level. METHODS A nationally representative cross-sectional survey was conducted to collect 24-h urine specimens from Chinese adults aged ≥18 y as part of the China National Nutrition Survey 2015. Finally, 10,114 participants (4932 males and 5182 females) with complete 24-h urine specimens were included in the analysis. Estimates of mean urinary electrolyte excretion and demographic, socioeconomic, and health characteristics were used with weighted coefficients that accounted for sample selection probabilities, poststratification weighting, and nonresponse rates. RESULTS The estimation of overall weighted mean 24-h urinary sodium excretion was 4121 mg (95% confidence interval [CI]: 3993, 4250), 4155 mg (95% CI: 3993, 4317) in males and 4081 mg (95% CI: 3953, 4209) in females (P for sex difference = 0.36). Overall mean 24-h urinary potassium excretion was 1534 mg (95% CI: 1492, 1577), 1468 mg (95% CI: 1424, 1513) in males and 1614 mg (95% CI: 1569-1660) in females (P for sex difference <0.001). Mean 24-h urinary sodium excretion was significantly higher in rural adults (4350 mg; 95% CI: 4217, 4483) than in urban residents (3909 mg; 95% CI: 3739, 4080; P < 0.001), and in northern residents (4388 mg; 95% CI: 4237, 4539) than in southern residents (3998 mg; 95% CI: 3832, 4163; P = 0.002). CONCLUSIONS The first nationwide survey with 24-h urine collection confirmed that mean sodium intake in Chinese adults was more than twice the upper limit, whereas mean potassium intake was <60% of the lower limit, recommended by the World Health Organization. Urgent measures should be taken to reduce sodium intake and increase potassium intake in China.

Stakeholder perspectives on Nigeria's national sodium reduction program: Lessons for implementation and scale-up. PLoS One 2023; 18:e0280226. [PMID: 36638099 PMCID: PMC9838847 DOI: 10.1371/journal.pone.0280226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Accepted: 12/26/2022] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND To reduce excess dietary sodium consumption, Nigeria's 2019 National Multi-sectoral Action Plan (NMSAP) for the Prevention and Control of Non-communicable Diseases includes policies based on the World Health Organization SHAKE package. Priority actions and strategies include mandatory sodium limits in processed foods, advertising restrictions, mass-media campaigns, school-based interventions, and improved front-of-package labeling. We conducted a formative qualitative evaluation of stakeholders' knowledge, and potential barriers as well as effective strategies to implement these NMSAP priority actions. METHODS From January 2021 to February 2021, key informant interviews (n = 23) and focus group discussions (n = 5) were conducted with regulators, food producers, consumers, food retailers and restaurant managers, academia, and healthcare workers in Nigeria. Building on RE-AIM and the Consolidated Framework for Implementation Research, we conducted directed content qualitative analysis to identify anticipated implementation outcomes, barriers, and facilitators to implementation of the NMSAP sodium reduction priority actions. RESULTS Most stakeholders reported high appropriateness of the NMSAP because excess dietary sodium consumption is common in Nigeria and associated with high hypertension prevalence. Participants identified multiple barriers to adoption and acceptability of implementing the priority actions (e.g., poor population knowledge on the impact of excess salt intake on health, potential profit loss, resistance to change in taste) as well as facilitators to implementation (e.g., learning from favorable existing smoking reduction and advertising strategies). Key strategies to strengthen NMSAP implementation included consumer education, mandatory and improved front-of-package labeling, legislative initiatives to establish maximum sodium content limits in foods and ingredients, strengthening regulation and enforcement of food advertising restrictions, and integrating nutrition education into school curriculum. CONCLUSION We found that implementation and scale-up of the Nigeria NMSAP priority actions are feasible and will require several implementation strategies ranging from community-focused education to strengthening current and planned regulation and enforcement, and improvement of front-of-package labeling quality, consistency, and use.

Sodium Content and Labelling of Packaged Foods and Beverages in Nigeria: A Cross-Sectional Study. Nutrients 2022; 15:nu15010027. [PMID: 36615685 PMCID: PMC9823880 DOI: 10.3390/nu15010027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 12/11/2022] [Accepted: 12/12/2022] [Indexed: 12/24/2022] Open
Abstract
Increased consumption of unhealthy processed foods, particularly those high in sodium, is a major risk factor for cardiovascular diseases. The nutrition information on packaged foods can help guide consumers toward products with less sodium and support government actions to improve the healthiness of the food supply. The aims of this study were to estimate the proportion of packaged foods displaying nutrition information for sodium and other nutrients specified by Nigerian nutrition labelling regulations and to determine the amount of sodium in packaged foods sold in Nigeria using data from the nutritional information panel. Data were collected from November 2020 to March 2021 from in-store surveys conducted in supermarkets in three states. A total of 7039 products were collected. Overall, 91.5% (n = 6439) provided only partial nutrition information, 7.0% (n = 495) provided no nutritional information, and only 1.5% (n = 105) displayed a nutrient declaration that included all nutrients specified by 2019 Nigerian regulations. Some form of sodium content information was displayed for 86% of all products (n = 6032), of which around 45% (n = 2689) expressed this as 'salt' and 59% (n = 3559) expressed this as 'sodium', while a small number of food products had both 'salt' and 'sodium' content (3.6%). Provision of sodium or salt information on the label varied between food categories, ranging from 50% (vitamins and supplements, n = 2/4) to 96% (convenience foods, n = 44/46). Food categories with the highest median sodium content were 'meat and meat alternatives' (904 mg/100 g), 'sauces, dressings, spreads, and dips' (560 mg/100 g), and 'snack foods' (536 mg/100 g), although wide variation was often observed within categories. These findings highlight considerable potential to improve the availability and consistency of nutrition information on packaged products in Nigeria and to introduce further policies to reduce the amount of sodium in the Nigerian food supply.
