Scaling hypertension treatment in 24 low-income and middle-income countries: economic evaluation of treatment decisions at three blood pressure cut-points.

OBJECTIVE: Estimate the incremental costs and benefits of scaling up hypertension care in adults in 24 select countries, using three different systolic blood pressure (SBP) treatment cut-off points-≥140, ≥150 and ≥160 mm Hg. INTERVENTION: Strengthening the hypertension care cascade compared with status quo levels, with pharmacological treatment administered at different cut-points depending on the scenario. TARGET POPULATION: Adults aged 30+ in 24 low-income and middle-income countries spanning all world regions. PERSPECTIVE: Societal. TIME HORIZON: 30 years. DISCOUNT RATE: 4%. COSTING YEAR: 2020 USD. STUDY DESIGN: DATA SOURCES: Institute for Health Metrics and Evaluation's Epi Visualisations database-country-specific cardiovascular disease (CVD) incidence, prevalence and death rates. Mean SBP and prevalence-National surveys and NCD-RisC. Treatment protocols-WHO HEARTS. Treatment impact-academic literature. Costs-national and international databases. OUTCOME MEASURES: Health outcomes-averted stroke and myocardial infarction events, deaths and disability-adjusted life-years; economic outcomes-averted health expenditures, value of averted mortality and workplace productivity losses. RESULTS OF ANALYSIS: Across 24 countries, over 30 years, incremental scale-up of hypertension care for adults with SBP≥140 mm Hg led to 2.6 million averted CVD events and 1.2 million averted deaths (7% of expected CVD deaths). 68% of benefits resulted from treating those with very high SBP (≥160 mm Hg). 10 of the 12 highest-income countries projected positive net benefits at one or more treatment cut-points, compared with 3 of the 12 lowest-income countries. Treating hypertension at SBP≥160 mm Hg maximised the net economic benefit in the lowest-income countries. LIMITATIONS: The model only included a few hypertension-attributable diseases and did not account for comorbid risk factors. Modelled scenarios assumed ambitious progress on strengthening the care cascade. CONCLUSIONS: In areas where economic considerations might play an outsized role, such as very low-income countries, prioritising treatment to populations with severe hypertension can maximise benefits net of economic costs.

Maintenance of Normal Blood Pressure From Middle to Older Age: Results From the Atherosclerosis Risk in Communities Study.

BACKGROUND: It is unknown whether maintaining normal blood pressure (BP) from middle to older age is associated with improved health outcomes. METHODS: We estimated the proportion of Atherosclerosis Risk in Communities study participants who maintained normal BP from 1987 to 1989 (visit 1) through 1996 to 1998 and 2011 to 2013 (over 4 and 5 visits, respectively). Normal BP was defined as systolic BP <120 mm Hg and diastolic BP <80 mm Hg, without antihypertensive medication. We estimated the risk of cardiovascular disease, dementia, and poor physical functioning after visit 5. In exploratory analyses, we examined participant characteristics associated with maintaining normal BP. RESULTS: Among 2699 participants with normal BP at baseline (mean age 51.3 years), 47.1% and 15.0% maintained normal BP through visits 4 and 5, respectively. The hazard ratios comparing participants who maintained normal BP through visit 4 but not visit 5 and through visit 5 versus those who did not maintain normal BP through visit 4 were 0.80 (95% CI, 0.63-1.03) and 0.60 (95% CI, 0.42-0.86), respectively, for cardiovascular disease, and 0.85 (95% CI, 0.71-1.01) and 0.69 (95% CI, 0.54-0.90), respectively, for poor physical functioning. Maintaining normal BP through visit 5 was more common among participants with normal body mass index versus obesity at visit 1, those with normal body mass index at visits 1 and 5, and those with overweight at visit 1 and overweight or normal body mass index at visit 5, compared with those with obesity at visits 1 and 5. CONCLUSIONS: Maintaining normal BP was associated with a lower risk of cardiovascular disease and poor physical functioning.

ACHIEVE conference proceedings: implementing action plans to reduce and control hypertension burden in Africa.

The prevalence of hypertension, the commonest risk factor for preventable disability and premature deaths, is rapidly increasing in Africa. The African Control of Hypertension through Innovative Epidemiology, and a Vibrant Ecosystem [ACHIEVE] conference was convened to discuss and initiate the co-implementation of the strategic solutions to tame this burden toward achieving a target of 80% for awareness, treatment, and control by the year 2030. Experts, including the academia, policymakers, patients, the WHO, and representatives of various hypertension and cardiology societies generated a 12-item communique for implementation by the stakeholders of the ACHIEVE ecosystem at the continental, national, sub-national, and local (primary) healthcare levels.

Role of Diuretics in Cardiovascular Events and Mortality in Systolic Blood Pressure Intervention Trial: A Post Hoc Analysis.

BACKGROUND: In a post hoc analysis, we examined whether postrandomization diuretics use can explain and/or mediate the beneficial effects of intensive systolic BP lowering on cardiovascular disease and all-cause mortality in the Systolic Blood Pressure Intervention Trial (SPRINT). METHODS: SPRINT was a randomized, controlled trial of 9361 participants comparing the effects of intensive (systolic BP target <120 mm Hg) versus standard (systolic BP target <140 mm Hg) BP control on a primary composite cardiovascular end point in participants aged 50 years or older with systolic BP of 130-180 mm Hg. In time-varying multivariable Cox analyses, we assessed hazard ratios (HRs) of cardiovascular end points and all-cause mortality in participants on thiazide type, loop and/or potassium (K) sparing, or no diuretics. We also conducted mediation analysis to formally assess the role of diuretics in the effects of intensive systolic BP lowering. RESULTS: At baseline, diuretics were prescribed in 46% and 48% of participants in standard and intensive systolic BP-lowering groups, respectively, and in 46% and 74% in the corresponding groups during the trial. The lower risk of cardiovascular end points in the intensive group (HR, 0.75; 95% confidence interval [CI], 0.64 to 0.89) persisted after adjustment for postrandomization time-varying diuretics use (HR, 0.74; 95% CI, 0.62 to 0.89). Across the entire study population, time-varying diuretics use was not associated with cardiovascular end points (compared with no diuretics, HR for thiazide type, 0.89; 95% CI, 0.73 to 1.10, and loop/K sparing, 1.29; 95% CI, 0.97 to 1.73). However, thiazide-type diuretics were associated with lower risk of cardiovascular end points in the intensive (HR, 0.62; 95% CI, 0.46 to 0.85) but not in the standard (HR, 1.07; 95% CI, 0.82 to 1.39) group. In mediation analysis, HRs for total effect, direct effect (not mediated through diuretics use), and indirect effect (mediated through diuretics) of the intervention on cardiovascular end points were 0.66 (95% CI, 0.54 to 0.79), 0.67 (95% CI, 0.54 to 0.81), and 0.98 (95% CI, 0.88 to 1.10), respectively. The results were largely similar for all-cause mortality. CONCLUSIONS: The favorable effects of intensive systolic BP lowering on cardiovascular end points and all-cause mortality in SPRINT were independent of and not mediated by time-varying diuretics use. However, thiazide-type diuretics use associated with benefit if intensive systolic BP lowering was targeted.

Effect of Intensive Blood Pressure Control on Kidney Outcomes: Long-Term Electronic Health Record-Based Post-Trial Follow-Up of SPRINT.

BACKGROUND: Intensive BP lowering in the Systolic Blood Pressure Intervention Trial (SPRINT) produced acute decreases in kidney function and higher risk for AKI. We evaluated the effect of intensive BP lowering on long-term changes in kidney function using trial and outpatient electronic health record (EHR) creatinine values. METHODS: SPRINT data were linked with EHR data from 49 (of 102) study sites. The primary outcome was the total slope of decline in eGFR for the intervention phase and the post-trial slope of decline during the observation phase using trial and outpatient EHR values. Secondary outcomes included a ≥30% decline in eGFR to <60 ml/min per 1.73 m 2 and a ≥50% decline in eGFR or kidney failure among participants with baseline eGFR ≥60 and <60 ml/min per 1.73 m 2 , respectively. RESULTS: EHR creatinine values were available for a median of 8.3 years for 3041 participants. The total slope of decline in eGFR during the intervention phase was -0.67 ml/min per 1.73 m 2 per year (95% confidence interval [CI], -0.79 to -0.56) in the standard treatment group and -0.96 ml/min per 1.73 m 2 per year (95% CI, -1.08 to -0.85) in the intensive treatment group ( P < 0.001). The slopes were not significantly different during the observation phase: -1.02 ml/min per 1.73 m 2 per year (95% CI, -1.24 to -0.81) in the standard group and -0.85 ml/min per 1.73 m 2 per year (95% CI, -1.07 to -0.64) in the intensive group. Among participants without CKD at baseline, intensive treatment was associated with higher risk of a ≥30% decline in eGFR during the intervention (hazard ratio, 3.27; 95% CI, 2.43 to 4.40), but not during the postintervention observation phase. In those with CKD at baseline, intensive treatment was associated with a higher hazard of eGFR decline only during the intervention phase (hazard ratio, 1.95; 95% CI, 1.03 to 3.70). CONCLUSIONS: Intensive BP lowering was associated with a steeper total slope of decline in eGFR and higher risk for kidney events during the intervention phase of the trial, but not during the postintervention observation phase.

The HEARTS partner forum-supporting implementation of HEARTS to treat and control hypertension.

Cardiovascular diseases (CVD), principally ischemic heart disease (IHD) and stroke, are the leading causes of death (18. 6 million deaths annually) and disability (393 million disability-adjusted life-years lost annually), worldwide. High blood pressure is the most important preventable risk factor for CVD and deaths, worldwide (10.8 million deaths annually). In 2016, the World Health Organization (WHO) and the United States Centers for Disease Control (CDC) launched the Global Hearts initiative to support governments in their quest to prevent and control CVD. HEARTS is the core technical package of the initiative and takes a public health approach to treating hypertension and other CVD risk factors at the primary health care level. The HEARTS Partner Forum, led by WHO, brings together the following 11 partner organizations: American Heart Association (AHA), Center for Chronic Disease Control (CCDC), International Society of Hypertension (ISH), International Society of Nephrology (ISN), Pan American Health Organization (PAHO), Resolve to Save Lives (RTSL), US CDC, World Hypertension League (WHL), World Heart Federation (WHF) and World Stroke Organization (WSO). The partners support countries in their implementation of the HEARTS technical package in various ways, including providing technical expertise, catalytic funding, capacity building and evidence generation and dissemination. HEARTS has demonstrated the feasibility and acceptability of a public health approach, with more than seven million people already on treatment for hypertension using a simple, algorithmic HEARTS approach. Additionally, HEARTS has demonstrated the feasibility of using hypertension as a pathfinder to universal health coverage and should be a key intervention of all basic benefit packages. The partner forum continues to find ways to expand support and reinvigorate enthusiasm and attention on preventing CVD. Proposed future HEARTS Partner Forum activities are related to more concrete information sharing between partners and among countries, expanded areas of partner synergy, support for implementation, capacity building, and advocacy with country ministries of health, professional societies, academy and civil societies organizations. Advancing toward the shared goals of the HEARTS partners will require a more formal, structured approach to the forum and include goals, targets and published reports. In this way, the HEARTS Partner Forum will mirror successful global partnerships on communicable diseases and assist countries in reducing CVD mortality and achieving global sustainable development goals (SDGs).

Alcohol Intake and Blood Pressure Levels: A Dose-Response Meta-Analysis of Nonexperimental Cohort Studies.

BACKGROUND: Alcohol consumption may increase blood pressure but the details of the relationship are incomplete, particularly for the association at low levels of alcohol consumption, and no meta-analyses are available for nonexperimental cohort studies. METHODS: We performed a systematic search of longitudinal studies in healthy adults that reported on the association between alcohol intake and blood pressure. Our end points were the mean differences over time of systolic (SBP) and diastolic blood pressure (DBP), plotted according to baseline alcohol intake, by using a dose-response 1-stage meta-analytic methodology. RESULTS: Seven studies, with 19 548 participants and a median follow-up of 5.3 years (range, 4-12 years), were included in the analysis. We observed a substantially linear positive association between baseline alcohol intake and changes over time in SBP and DBP, with no suggestion of an exposure-effect threshold. Overall, average SBP was 1.25 and 4.90 mm Hg higher for 12 or 48 grams of daily alcohol consumption, compared with no consumption. The corresponding differences for DBP were 1.14 and 3.10 mm Hg. Subgroup analyses by sex showed an almost linear association between baseline alcohol intake and SBP changes in both men and women, and for DBP in men while in women we identified an inverted U-shaped association. Alcohol consumption was positively associated with blood pressure changes in both Asians and North Americans, apart from DBP in the latter group. CONCLUSIONS: Our results suggest the association between alcohol consumption and SBP is direct and linear with no evidence of a threshold for the association, while for DBP the association is modified by sex and geographic location.

[Association between population hypertension control and ischemic heart disease and stroke mortality in 36 countries of the Americas, 1990-2019: an ecological studyAssociação entre controle populacional da hipertensão e mortalidade por doença cardíaca isquêmica e acidente vascular cerebral em 36 países das Américas, 1990-2019: um estudo ecológico]. / Asociación entre el control de la hipertensión arterial en la población y la mortalidad por cardiopatía isquémica y accidente cerebrovascular en 36 países y territorios de la Región de las Américas, 1990-2019: un estudio ecológico.

Objective: To quantify the association between the prevalence of population hypertension control and ischemic heart disease (IHD) and stroke mortality in 36 countries of the Americas from 1990 to 2019. Methods: This ecologic study uses the prevalence of hypertension, awareness, treatment, and control from the NCD-RisC and IHD and stroke mortality from the Global Burden of Disease Study 2019. Regression analysis was used to assess time trends and the association between population hypertension control and mortality. Results: Between 1990 and 2019, age-standardized death rates due to IHD and stroke declined annually by 2.2% (95% confidence intervals: -2.4 to -2.1) and 1.8% (-1.9 to -1.6), respectively. The annual reduction rate in IHD and stroke mortality deaccelerated to -1% (-1.2 to -0.8) during 2000-2019. From 1990 to 2019, the prevalence of hypertension controlled to a systolic/diastolic blood pressure ≤140/90 mmHg increased by 3.2% (3.1 to 3.2) annually. Population hypertension control showed an inverse association with IHD and stroke mortality, respectively, regionwide and in all but 3 out of 36 countries. Regionwide, for every 1% increase in population hypertension control, our data predicted a reduction of 2.9% (-2.94 to -2.85) in IHD deaths per 100 000 population, equivalent to an averted 25 639 deaths (2.5 deaths per 100 000 population) and 2.37% (-2.41 to -2.33) in stroke deaths per 100 000 population, equivalent to an averted 9 650 deaths (1 death per 100 000 population). Conclusion: There is a strong ecological negative association between IHD and stroke mortality and population hypertension control. Countries with the best performance in hypertension control showed better progress in reducing CVD mortality. Prediction models have implications for hypertension management in most populations in the Region of the Americas and other parts of the world.

O controle populacional da hipertensão apresentou associação inversa com mortalidade por DCI e AVC, respectivamente, em toda a região, e em todos os 36 países, com a exceção de três. Em toda a região, para cada 1% de aumento no controle populacional da hipertensão, nossos dados previram uma redução de 2,9% (−2,94 a −2,85) nos óbitos por DCI por 100 000 habitantes, equivalente à prevenção de 25 639 óbitos (2,5 óbitos por 100 000 habitantes), e de 2,37% (−2,41 a −2,33) nos óbitos por AVC por 100 000 habitantes, equivalente à prevenção de 9 650 óbitos (1 óbito por 100 000 habitantes). Conclusão: Existe forte associação ecológica negativa entre mortalidade por DCI e AVC e controle populacional da hipertensão. Os países com o melhor desempenho no controle da hipertensão mostraram melhor progresso na redução da mortalidade por doenças cardiovasculares.

[RESUMEN]. Objetivo. Cuantificar la asociación entre la prevalencia de control de la hipertensión arterial a nivel poblacional y la mortalidad por cardiopatía isquémica y accidente cerebrovascular en 36 países y territorios de la Región de las Américas entre 1990 y el 2019. Métodos. Este estudio ecológico emplea la prevalencia de la hipertensión, la concientización, el tratamiento y el control de la hipertensión arterial en la población producidos por la Colaboración sobre Factores de Riesgo de las Enfermedades No Transmisibles (NCD-RisC, por su sigla en inglés) y estimaciones de mortalidad por cardiopatía isquémica y accidente cerebrovascular del estudio sobre la carga mundial de enfermedad del 2019. Se realizó un análisis de regresión para evaluar las tendencias temporales y la asociación entre el con- trol de la hipertensión arterial en la población y la mortalidad. Resultados. Entre 1990 y el 2019, las tasas de mortalidad estandarizadas por edad a causa de cardiopatía isquémica y accidente cerebrovascular disminuyeron en 2,2% (intervalos de confianza de 95%: –2,4 a –2,1) y 1,8% (–1,9 a –1,6) anual, respectivamente. La tasa de reducción anual de la mortalidad por cardiopatía isquémica y accidente cerebrovascular se redujo a –1% (–1,2 a –0,8) entre el 2000 y el 2019. Del 1990 al 2019, la prevalencia de hipertensión arterial controlada definida como presión arterial sistólica/diastólica ≤140/90 mmHg aumentó anualmente en 3,2% (3,1 a 3,2). Se observó una relación inversa entre el control poblacional de la hipertensión y la mortalidad por cardiopatía isquémica y por accidente cerebrovascular, respectivamente, en toda la Región y en los 36 países, a excepción de tres. En toda la Región, por cada aumento de 1% en el control de la hipertensión arterial en la población, nuestros datos predijeron una reduc- ción de 2,9% (–2,94 a –2,85) en las muertes por cardiopatía isquémica por 100 000 habitantes, equivalente a 25 639 muertes evitables (2,5 muertes por 100 000 habitantes) y de 2,37% (–2,41 a –2,33) en las muertes por accidente cerebrovascular por 100000 habitantes, equivalente a 9 650 muertes evitables (una muerte por 100 000 habitantes). Conclusiones. Existe una sólida asociación ecológica negativa entre la mortalidad por cardiopatía isquémica y accidente cerebrovascular y el control de la hipertensión arterial en la población. Los países con mejor resultado en el control de la hipertensión mostraron un mayor progreso en la reducción de la mortalidad por enfermedad cardiovascular. Los modelos de predicción tienen implicaciones en el manejo de la hipertensión en la mayoría de los grupos poblacionales de la Región de las Américas y otras partes del mundo.

Estimated Population Health Benefits of Intensive Systolic Blood Pressure Treatment Among SPRINT-Eligible US Adults.

BACKGROUND: The Systolic Blood Pressure Intervention Trial (SPRINT) demonstrated an intensive (<120 mm Hg) vs. standard (<140 mm Hg) systolic blood pressure (SBP) goal lowered cardiovascular disease (CVD) risk. Estimating the effect of intensive SBP lowering among SPRINT-eligible adults most likely to benefit can guide implementation efforts. METHODS: We studied SPRINT participants and SPRINT-eligible participants in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study and National Health and Nutrition Examination Surveys (NHANES). A published algorithm of predicted CVD benefit with intensive SBP treatment was used to categorize participants into low, medium, or high predicted benefit. CVD event rates were estimated with intensive and standard treatment. RESULTS: Median age was 67.0, 72.0, and 64.0 years in SPRINT, SPRINT-eligible REGARDS, and SPRINT-eligible NHANES participants, respectively. The proportion with high predicted benefit was 33.0% in SPRINT, 39.0% in SPRINT-eligible REGARDS, and 23.5% in SPRINT-eligible NHANES. The estimated difference in CVD event rate (standard minus intensive) was 7.0 (95% confidence interval [CI] 3.4-10.7), 8.4 (95% CI 8.2-8.5), and 6.1 (95% CI 5.9-6.3) per 1,000 person-years in SPRINT, SPRINT-eligible REGARDS participants, and SPRINT-eligible NHANES participants, respectively (median 3.2-year follow-up). Intensive SBP treatment could prevent 84,300 (95% CI 80,800-87,920) CVD events per year in 14.1 million SPRINT-eligible US adults; 29,400 and 28,600 would be in 7.0 million individuals with medium or high predicted benefit, respectively. CONCLUSIONS: Most of the population health benefit from intensive SBP goals could be achieved by treating those characterized by a previously published algorithm as having medium or high predicted benefit.

Editors' Commentary on the 2023 ESH Management of Arterial Hypertension Guidelines.

Clinical practice guidelines are ideally suited to the provision of advice on the prevention, diagnosis, evaluation, and management of high blood pressure (BP). The recently published European Society of Hypertension (ESH) 2023 ESH Guidelines for the management of arterial hypertension is the latest in a long series of high BP clinical practice guidelines. It closely resembles the 2018 European Society of Cardiology/ESH guidelines, with incremental rather than major changes. Although the ESH guidelines are primarily written for European clinicians and public health workers, there is a high degree of concordance between its recommendations and those in the other major BP guidelines. Despite the large number of national and international BP guidelines around the world, general population surveys demonstrate that BP guidelines are not being well implemented in any part of the world. The level of BP, which is the basis for diagnosis and management, continues to be poorly measured in routine clinical practice and control of hypertension remains suboptimal, even to a conservative BP target such as a systolic/diastolic BP <140/90 mm Hg. BP guidelines need to focus much more on implementation of recommendations for accurate diagnosis and strategies for improved control in those being treated for hypertension. An evolving body of implementation science can assist in meeting this goal. Given the enormous health, social, and financial burden of high BP, better diagnosis and management should be an imperative for clinicians, government, and others responsible for the provision of health care services. Hopefully, the 2023 ESH will help enable this.

African Control of Hypertension through Innovative Epidemiology and a Vibrant Ecosystem (ACHIEVE): novel strategies for accelerating hypertension control in Africa.

Hypertension is a leading preventable and controllable risk factor for cardiovascular and cerebrovascular diseases and the leading preventable risk for death globally. With a prevalence of nearly 50% and 93% of cases uncontrolled, very little progress has been made in detecting, treating, and controlling hypertension in Africa over the past thirty years. We propose the African Control of Hypertension through Innovative Epidemiology and a Vibrant Ecosystem (ACHIEVE) to implement the HEARTS package for improved surveillance, prevention, treatment/acute care of hypertension, and rehabilitation of those with hypertension complications across the life course. The ecosystem will apply the principles of an iterative implementation cycle by developing and deploying pragmatic solutions through the contextualization of interventions tailored to navigate barriers and enhance facilitators to deliver maximum impact through effective communication and active participation of all stakeholders in the implementation environment. Ten key strategic actions are proposed for implementation to reduce the burden of hypertension in Africa.

Concordance between clinical outcomes in the Systolic Blood Pressure Intervention Trial and in the electronic health record.

BACKGROUND: Randomized trials are the gold standard for generating clinical practice evidence, but follow-up and outcome ascertainment are resource-intensive. Electronic health record (EHR) data from routine care can be a cost-effective means of follow-up, but concordance with trial-ascertained outcomes is less well-studied. METHODS: We linked EHR and trial data for participants of the Systolic Blood Pressure Intervention Trial (SPRINT), a randomized trial comparing intensive and standard blood pressure targets. Among participants with available EHR data concurrent to trial-ascertained outcomes, we calculated sensitivity, specificity, positive predictive value, and negative predictive value for EHR-recorded cardiovascular disease (CVD) events, using the gold standard of SPRINT-adjudicated outcomes (myocardial infarction (MI)/acute coronary syndrome (ACS), heart failure, stroke, and composite CVD events). We additionally compared the incidence of non-CVD adverse events (hyponatremia, hypernatremia, hypokalemia, hyperkalemia, bradycardia, and hypotension) in trial versus EHR data. RESULTS: 2468 SPRINT participants were included (mean age 68 (SD 9) years; 26% female). EHR data demonstrated ≥80% sensitivity and specificity, and ≥ 99% negative predictive value for MI/ACS, heart failure, stroke, and composite CVD events. Positive predictive value ranged from 26% (95% CI; 16%, 38%) for heart failure to 52% (95% CI; 37%, 67%) for MI/ACS. EHR data uniformly identified more non-CVD adverse events and higher incidence rates compared with trial ascertainment. CONCLUSIONS: These results support a role for EHR data collection in clinical trials, particularly for capturing laboratory-based adverse events. EHR data may be an efficient source for CVD outcome ascertainment, though there is clear benefit from adjudication to avoid false positives.

It is strongly recommended to not conduct, fund, or publish research studies that use spot urine samples with estimating equations to assess individuals' sodium (salt) intake in association with health outcomes: a policy statement of the World Hypertension League, International Society of Hypertension and Resolve to Save Lives.

Spot urine samples with estimating equations have been used to assess individuals' sodium (salt) intake in association with health outcomes. There is large random and systematic error in estimating sodium intake using this method and spurious health outcome associations. Substantial controversy has resulted from false claims the method is valid. Hence, the World Hypertension League, International Society of Hypertension and Resolve to Save Lives, supported by 21 other health organizations, have issued this policy statement that strongly recommends that research using spot urine samples with estimating equations to assess individuals' sodium (salt) intake in association with health outcomes should not be conducted, funded or published. Literature reviews on the health impacts of reducing dietary sodium that include studies that have used spot and short duration timed urine samples with estimating equations need to explicitly acknowledge that the method is not recommended to be used and is associated with spurious health outcome associations.
