1. Formulas developed based on the ratio of urea nitrogen to creatinine concentrations obtained from multiple spot urine samples are acceptable to predict protein intake at group level but not at individual level

Subject:
creatinine; excretion; men; protein intake; standard deviation; t-test; urea nitrogen; urine; women; Japan
Abstract:
... In this study, we hypothesized that spot urine can be used to predict protein intake at both group and individual levels. Participants (n = 369) of this study were recruited from all 47 prefectures in Japan. Sex-specific formulas were developed based on the ratio of urea nitrogen to creatinine concentration obtained from 3 spot urine samples. Validity of the formulas was examined against two 24-ho ...

Abstract:
... The effectiveness of better nutrition knowledge and dietary behavior on healthier dietary intake is still controversial. We hypothesized that nutritional knowledge and dietary behavior are associated with sodium and potassium intake in adult women. A cross-sectional study was conducted at welfare facilities located in 20 areas of Japan. Ninety-nine female dietitians and 117 nondietitians aged 20 t ...

3. The degree of misreporting of the energy-adjusted intake of protein, potassium, and sodium does not differ among under-, acceptable, and over-reporters of energy intake

Subject:
correlation; diet history; dietary protein; energy intake; energy requirements; excretion; nutrient density; nutrients; potassium; protein intake; proteins; questionnaires; sodium; women
Abstract:
... It is unclear whether misreporting of nutrient intakes differs according to energy reporting status. We examined misreporting of dietary protein, potassium, and sodium in under-, acceptable, and over-reporters of energy intake. Our hypothesis was that degree of misreporting of these three nutrients differs among under-, acceptable, and over-reporters. Participants were 1043 Japanese women aged 18 ...

Subject:
food intake; elderly; Japanese people; urine; women; riboflavin; pyridoxine; elderly nutrition; folic acid; niacin; pantothenic acid; thiamin; excretion; ascorbic acid; Japan
Abstract:
... We hypothesized that 24-hour urinary excretion of water-soluble vitamins might correlate with their intake in free-living Japanese elderly females aged 70 to 84 years. We performed a cross-sectional study composed of 37 healthy, elderly, Japanese females living freely. All foods and the corresponding weights consumed for 4 consecutive days were recorded accurately. A 24-hour urine sample was colle ...
