Personalised Advice for the Prevention of Metabolic Syndrome
Personalised Dietary Advice for Highly Motivated Consumers at Risk of Metabolic Syndrome - a Pilot Study
Rationale: Improving dietary behaviours in view of optimising risk factors of metabolic syndrome requires behaviour change strategies. Tailored dietary advice, i.e. recommendations offered as a guide to action, can support behaviour change. In the current study we aim to learn how to better help consumers in their daily life to make lifestyle choices that better match their personal health target than their usual choices by providing personalised advice and feedback. In this study we target consumers at risk of metabolic syndrome (MetS) that are highly motivated to change their dietary behaviour in view of improving health.
Objective: The primary objective is to investigate the potential of personalised dietary advice and feedback for initiating and maintaining dietary changes by consumers at risk of MetS. In addition we want to evaluate understanding, applicability and personal benefit of personalised dietary advice and feedback by the target population to be able to further optimize the personalisation in future studies. The secondary objective is to explore potential effects of personalised dietary advice and feedback on subjective health and metabolic health parameters.
Study design: The study follows a one group pre-test post-test design with a duration of 16 weeks after the first advice is provided to the participants.
Study population: In total 40 adult men and women at risk of metabolic syndrome will be recruited from the consumer databases of Wageningen Food & Biobased Research. Consumers are eligible for study participation when they are highly motivated to change dietary behaviour, willing to use technology, willing to share food purchase data as registered on a customer card of the supermarket, and in possession of a smart-phone.
Intervention: The intervention consists of personalised dietary advice and feedback on actual behaviour and health status that will be provided to study participants at set time points throughout the study period. The content of the advice will be generated partly automated based on dietary intake and parameters of metabolic health using knowledge rules that are developed for this study. During a consultation with the dietician, the advice is then translated in a dietary behaviour change strategy by taking into account individual preferences through motivational interviewing.
Main study parameters/endpoints: Primary outcomes of the study are the adequacy of intake of fruits, vegetables, whole grain products, dairy, fish, fats & oils, red meat, processed meat, and sweetened beverages & fruit juices as estimated by the online tool Eetscore. Furthermore consumer experiences and individual benefits of the provided personalised dietary advice are monitored on a weekly basis throughout the intervention period.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Dietary quality at baseline
Time Frame: Baseline (week 0)
|
Dietary quality was assessed by an online version of the Dutch Healthy Diet Index (DHDI) ('Eetscore', Division of Human Nutrition, Wageningen University).
The DHDI evaluates adherence to the Dutch dietary guidelines per food category (score 1-10) and a total score (score 8-80).
|
Baseline (week 0)
|
Dietary quality halfway
Time Frame: halfway (week 8)
|
Dietary quality was assessed by an online version of the Dutch Healthy Diet Index (DHDI) ('Eetscore', Division of Human Nutrition, Wageningen University).
The DHDI evaluates adherence to the Dutch dietary guidelines per food category (score 1-10) and a total score (score 8-80).

Dietary quality at study end
Time Frame: study end (week 16)

Changes in Self perceived health during study period
Time Frame: Baseline (week 0) and study end (week 16)
|
questionnaire to evaluate 1-self-perceived health status, 2-healthiness of the diet and 3-satisfaction with actual diet.
Items All items were evaluated on a 7-point scale.
For items 1 and 2, the scale ranged from 1=very unhealthy up to 7=very healthy.
For item 3, the scale ranged from 1=very unsatisfied up to 7=very satisfied
