Estimation of daily sodium and potassium excretion using spot urine and 24-hour urine samples in a black population (Benin).
The 24-hour urine collection method is considered the gold standard for the estimation of ingested potassium and sodium. Because of the impracticalities of collecting all urine over a 24-hour period, spot urine is often used for epidemiological investigations. This study aims to assess the agreement between spot urine and 24-hour urine measurements to determine sodium and potassium intake. A total of 402 participants aged 25 to 64 years were randomly selected in South Benin. Spot urine was taken during the second urination of the day. Twenty-four-hour urine was also collected. Samples (2-mL) were taken and then stored at -20°C. The analysis was carried out using potentiometric dosage. The agreement between spot urine and 24-hour urine measurements was established using Bland-Altman plots. A total of 354 results were analyzed. Daily sodium chloride and potassium chloride urinary excretion means were 10.2±4.9 g/24 h and 2.9±1.4 g/24 h, respectively. Estimated daily sodium chloride and potassium chloride means from the spot urine were 10.7±7.0 g/24 h and 3.9±2.1 g/24 h, respectively. Concordance coefficients were 0.61 at d=-0.5 g, (d±2SD=-11 g and 10.1 g) for sodium chloride and 0.61 at d=-1 g, (d±2SD=-3.8 g and 1.8 g) for potassium chloride. Spot urine method is acceptable for estimating 24-hour urinary sodium and potassium excretion to assess sodium and potassium intake in a black population. However, the confidence interval for the mean difference, which is too large, makes the sodium chloride results inadmissible at a clinical level

Dietary sodium and potassium intakes: Data from urban and rural areas.
Hypertension is highly prevalent in West African populations, but little data is available on salt and potassium intake in these populations. We assumed in this study that sodium and potassium intake might be high and low, respectively, in the Beninese population in view of the emerging nutritional transition. The aim of this study was to estimate dietary sodium and potassium intakes based on 24-h urine collections.
We selected 420 individuals (ages 25-64 y), representative of the population, from urban and rural areas in Benin. Urine was collected over 24 h, and sodium, potassium, and creatinine were quantified. Blood pressure was measured on the left arm using a validated electronic oscillometric monitor.
Adequate data were available for 354 participants. Mean dietary intake of sodium and potassium were 4.4 ± 2.1 and 1.8 ± 0.9 g/24 h, respectively. High intake of sodium was associated with urban area, age <44 y, administrative occupation, higher income, body mass index (BMI) ≥25 kg/m(2), and a large waist circumference. High potassium intake was associated with male sex, administrative occupation, BMI ≥25 kg/m(2), and large waist circumference. Sodium intake was associated with high systolic and diastolic blood pressures. In multivariate analysis, only age <44 y and, marginally, BMI ≥25 kg/m(2) were associated with high sodium intake, whereas male sex and a BMI ≥25 kg/m(2) were associated with high potassium intake.
Large proportions of the population had sodium intake higher, and potassium intake lower, than dietary recommendations. These results suggest that interventions to reduce salt consumption and promote potassium-rich foods, including fruits and vegetables, are needed in Benin

Supplementary Material for: Population-Based Evidence that Survival in Amyotrophic Lateral Sclerosis Is Related to Weight Loss at Diagnosis
<p><b><i>Background/Aims:</i></b> In a population-based setting, we aimed to (i) describe weight loss (WL) of amyotrophic lateral sclerosis (ALS) patients at the time of diagnosis and (ii) evaluate the association between WL and survival. <b><i>Methods:</i></b> All patients recruited in the FRALim register (2000-2013) were considered to be included in this study. Time-to-death analyses were performed using a multivariable Cox model. Model discrimination and calibration were assessed. <b><i>Results:</i></b> Among 322 patients in the register, 261 (81%) were included. At the time of diagnosis, 50.6% of patients reported a WL of more than 5%: 14.6% with WL between 5 and 10% and 36.0% with a WL of more than 10%. WL was independently associated with survival (p = 0.002). Patients with a WL of 10% or more experienced a 45% increase in the risk of death (95% CI 6-99) with respect to patients with a WL lower than 5% or no WL. The introduction of WL significantly improved the model's discrimination achieving a survival C statistic of 79.5% (95% CI 75.6-83.5, p = 0.006) at 12 months. <b><i>Conclusion:</i></b> More than 50% of ALS patients experience a WL of more than 5% at the time of diagnosis. This finding highlights the need for randomized trials to evaluate the effect of nutritional interventions to improve ALS survival.</p
