App-based Protein Support for Older Adults; Coaching Towards Healthy Ageing

Обзор

Rationale: Sufficient dietary protein intake helps to preserve muscle mass and strength and is a key factor in healthy ageing. Achieving an increased protein intake with regular food products has shown to be a challenge for many older adults. Applying behavioural change techniques may facilitate a more sustained improvement in protein consumption over time. Objective: To investigate whether a nutritional app intervention can increase the protein intake (with the goal of 1.2 g/kg body weight/day) of older adults, using readily available food products. Secondary and tertiary objective include the effects of the intervention on body composition and muscle strength and long-term effects on protein intake.

Вмешательства

• Поведенческое Nutritional coaching via an app
  Coaching involves e-coaching via an app, supported by one telephone consultation. Within the SO-NUTS (preventing obesity, sarcopenia, and Sarcopenic Obesity in retirement through digital, personalised interventions for healthy NUTrition and physical activity for Seniors) project, BCTs are investigated that fit the older adult population. Insights gained from systematic review and focus group interviews are applied to the Eifit application.
• Поведенческое Exercise recommendations
  The objective is to adhere to the 2017 physical activity guidelines as set by the Health Council of the Netherlands i.e. "Engage in at least 150 minutes of moderate-intensity physical activity per week, perform muscle- and bone-strengthening activities at least twice a week in combination with balance exercises, and avoid prolonged periods of sitting." Participants in both groups have access to the application that contains a wide range of muscle and bone-strengthening activities, as well as bal
