Purpose: Recent studies suggest that 24-h urine osmolality (UOsm) for optimal water intake should be maintained < 500 mmol·kg. The purpose of this study was to determine the total water intake (TWI) requirement for healthy adults to maintain optimal hydration as indicated by 24-h urine osmolality < 500 mmol·kg.
Methods: Twenty-four-hour UOsm was assessed in 49 men and 50 women residing in the United States (age: 41 ± 14 y, body mass index: 26.
The purpose of this investigation was to assess the validity and reliability of a seven-day water frequency questionnaire (TWI-FQ) to estimate daily total water intake (TWI) in comparison to a water turnover objective reference value via deuterium oxide (DO). Data collection occurred over 3 weeks, with a wash-out period during week two. Healthy adults ( = 98; 52% female; 41 ± 14 y; BMI, 26.

Furthermore, a low water intake is associated with increased health risks, such as CKD. These issues are especially pressing in Mexico where SSB intake is high.

Subjects/methods: One hundred and one healthy adults (females n = 52, 40 ± 14 y, 1.70 ± 0.
Background: Bariatric surgery before pregnancy can result in improved maternal fertility. However, long-term data on the consequences at childhood age are currently lacking.
Methods: EFFECTOR is a prospective cohort study of children (aged 4 to 11 years) born to mothers who underwent bariatric surgery (BS) before pregnancy (n = 36), controls with overweight/obesity (OW/OB) matched on pre-pregnancy BMI (n = 36) and normal weight controls (NL) (n = 35).
