- ACRONYM
- hypothesisIn old age, sufficient protein intake is important to preserve muscle mass and function. Around 50% of older adults (65+ y) consumes ˇÜ1.0 g/kg adjusted body weight (BW)/day (d). There is no rapid method to screen for low protein intake in old age. Therefore, we aimed to develop and validate a short food questionnaire to screen for low protein intake in community-dwelling older adults.

- Inclusion criteriaWe used data of 1348 older men and women (56-101 y) of the LASA study (the Netherlands) to develop the questionnaire and data of 563 older men and women (55-71 y) of the HELIUS study (the Netherlands) for external validation.
- Exclusion criteriaMissing values on more than 11 the FFQ questions, missing data on BMI, use of meal replacement shakes on more than two weekdays per week, and implausible energy intake (<500 kcal or >3500 kcal for women and <800 kcal or >4000 kcal for men).

- Brief summaryBackground: In old age, sufficient protein intake is important to preserve muscle mass and function. Around 50% of older adults (65+ y) consumes ≤1.0 g/kg adjusted body weight (BW)/day (d). There is no rapid method available to screen for low protein intake in old age.
Objective: We aimed to develop and validate a short food questionnaire to screen for low protein intake in community-dwelling older adults.
Design: We will use data of 1348 older men and women (56-101 y) of the LASA study (the Netherlands) to develop the questionnaire and data of 563 older men and women (55-71 y) of the HELIUS study (the Netherlands) for external validation. In both samples, protein intake was measured by the 238-item semi-quantitative HELIUS food frequency questionnaire (FFQ). Multivariable logistic regression analysis will be used to predict protein intake ≤1.0 g/kg adjusted BW/d. Candidate predictor variables are FFQ questions on frequency and amount of intake of specific foods.
Results: not yet available.
