Total energy expenditure in healthy Chinese children (7–18) and adults (30–60) measured with doubly labeled water

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This nationwide observational project will recruit healthy children aged 7–18 and adults aged 30–60 at sites in Shenzhen, Chongqing, and Haikou to measure total energy expenditure. Participants will receive standardized anthropometric assessments (height, weight, waist and hip circumferences) and have energy expenditure quantified using the doubly labeled water technique over a defined measurement period. Individuals with malnutrition, overweight or obesity, recent acute illness, chronic diseases, musculoskeletal injuries, or disabilities will be excluded to define a healthy reference group. The data will be used to characterize typical energy requirements across age groups and help inform dietary recommendations and public health planning in China.
