Background
For persons with osteoarthritis (OA), nutrition education may facilitate weight and OA symptom management.
Objective
The primary aim of this study was to determine preferred OA-related nutritional and weight management topics and their preferred delivery modality. The secondary aim was to determine if there is a disconnect between what patients want to know about nutrition and OA management, and what information healthcare professionals (HCPs) are providing to patients.
Methods
The Osteoarthritis Action Alliance surveyed individuals with OA to identify their preferences, categorized in four domains: 1) Strategies for weight management/healthy lifestyle; 2) Vitamins/minerals/other supplements; 3) Foods/nutrients that may reduce inflammation; and 4) Diets for weight loss. HCPs were provided these domains and asked which topics they discussed with patients with OA. Both groups were asked to select currently utilized or preferred formats of nutritional resources.
Results
Survey responses from 338 individuals with OA and 104 HCPs were included. Highest preference rankings in each domain were: 1) foods that make OA symptoms worse (65%), foods/nutrients to reduce inflammation (57%), and healthy weight loss (42%); 2) glucosamine (53%), vitamin D (49%), and omega-3 fatty acids (45%); 3) spices/herbs (65%), fruits/vegetables (58%), and nuts (40%); and 4) Mediterranean diet (21%), low-carbohydrate diet (18%) and fasting/intermittent fasting (15%). There was greater than 20% discrepancy between OA person-reported interests and HCP-reported discussions on: weight loss strategies, general information on vitamins/minerals, special dietary considerations for other conditions, mindful eating, controlling caloric intake or portion size, and what foods worsen OA symptoms. Most respondents preferred to receive nutrition information in a passive format and did not want information from social media messaging.
Conclusions
There is disparity between nutrition education content preferred by individuals with OA (which often lacks empirical support) and evidence-based topics being discussed by HCPs. HCPs must communicate evidence-based management of joint health and OA symptoms in patient-preferred formats.
