Background Nutrition care can positively affect multiple aspects of patient’s health; outcomes are commonly
evaluated on the basis of their impact on a patient’s (i) illness-specific conditions and (ii) health-related quality of life
(HRQoL). Our systematic review examined how HRQoL was measured in studies of nutritional interventions. To help
future researchers select appropriate Quality of Life Questionnaires (QoLQ), we identified commonly-used instruments
and their uses across populations in different regions, of different ages, and with different diseases.
Methods We searched EMCare, EMBASE, and Medline databases for studies that had HRQoL and nutrition intervention
terms in the title, the abstract, or the MeSH term classifications “quality of life” and any of “nutrition therapy”, “diet
therapy”, or “dietary supplements” and identified 1,113 studies for possible inclusion.We then reviewed titles, abstracts,
and full texts to identify studies for final inclusion.
Results Our review of titles, abstracts, and full texts resulted in the inclusion of 116 relevant studies in our final
analysis. Our review identified 14 general and 25 disease-specific QoLQ. The most-used general QoLQ were the Short-
Form 36-Item Health Survey (SF-36) in 27 studies and EuroQol 5-Dimension, (EQ-5D) in 26 studies. The European
Organization for Research and Treatment of Cancer Quality of life Questionnaire (EORTC-QLQ), a cancer-specific
QoLQ, was the most frequently used disease-specific QoLQ (28 studies). Disease-specific QoLQ were also identified
for nutrition-related diseases such as diabetes, obesity, and dysphagia. Sixteen studies used multiple QoLQ, of which
eight studies included both general and disease-specific measures of HRQoL. The most studied diseases were
cancer (36 studies) and malnutrition (24 studies). There were few studies focused on specific age-group populations,
with only 38 studies (33%) focused on adults 65 years and older and only 4 studies focused on pediatric patients.
Regional variation in QoLQ use was observed, with EQ-5D used more frequently in Europe and SF-36 more commonly
used in North America.
Conclusions Use of QoLQ to measure HRQoL is well established in the literature; both general and disease-specific
instruments are now available for use. We advise further studies to examine potential benefits of using both general
and disease-specific QoLQ to better understand the impact of nutritional interventions on HRQoL.
