Elevated urinary Na/K ratio among Lebanese elementary school children is attributable to low K intake.

Purpose: To estimate total sodium (Na) and potassium (K) intake using non-fasting morning urine specimens among Lebanese elementary (6-10 year old) schoolchildren.

Method: A national cross-sectional study was conducted. A multistage cluster sampling procedure was used to select a representative sample of 1403 healthy children from the eight districts of Lebanon.

Lebanese children are iodine deficient and urinary sodium and fluoride excretion are weak positive predictors of urinary iodine.

Purpose: To assess iodine and fluoride status among Lebanese children.

Methods: A nationally representative cross-sectional study of 6- to 10-year-old schoolchildren was conducted using multistage cluster sampling. Spot urine samples were collected from 1403 children, and urinary iodine, fluoride, creatinine and sodium levels were measured.

Urinary Magnesium, Calcium, and Phosphorus to Creatinine Ratios of Healthy Elementary School Lebanese Children.

Urinary magnesium (Mg), calcium (Ca), and phosphorus (P) excretions are known to vary greatly between populations due to dietary habits, physical activity, mineral content of water, climate, genetics, and race. Thus, it is essential to determine the normal values in each population in order to assess the status as well as to diagnose any possible abnormality of metabolisms especially hypercalciuria. A study was conducted to determine urinary Mg/creatinine (Cr), Ca/Cr, and P/Cr ratios of healthy Lebanese elementary schoolchildren.

Phosphorus supplement alters postprandial lipemia of healthy male subjects: a pilot cross-over trial.

Background: Epidemiological studies have found a U-shaped relationship between serum phosphorus and cardiovascular disease (CVD). The mechanism(s) behind such a relationship are poorly understood. Phosphorus (P) is reported to improve insulin sensitivity, which is involved in lipid metabolism, and thus we were interested in determining the impact of phosphorus ingestion on postprandial lipemia, a recognized CVD risk factor.
