OBJECTIVE: To determine the effects of a digital voice assistant-delivered self-management program on dietary behaviours for supporting musculoskeletal health in postmenopausal women with osteoporosis.
METHODS: This was a secondary analysis of a 12-month randomised controlled feasibility trial evaluating the feasibility and effectiveness of a digital voice assistant intervention to support osteoporosis-related health behaviours, with 50 participants randomly assigned to a digital voice assistant intervention (N = 25) or control group (N = 25) for a 6-month intervention and an additional 6-month maintenance period. During the intervention period, the digital voice assistant group received videos focused on dairy foods, dairy alternatives, protein, calcium and vitamin D, via a digital voice assistant device located in their home. The control group received six emails with weblinks to osteoporosis information. Dietary intakes were assessed at baseline, 6 and 12 months via three-day food records.
RESULTS: Participants (mean age 64.3 ± 6.1 years) accessed approximately 80% of prescribed videos during the intervention. There were no significant within- or between-group changes in protein or calcium intakes at 6 or 12 months. Daily low-fat milk and egg servings increased in the digital voice assistant group compared with controls from baseline to 12 months (P = 0.02).
CONCLUSIONS: A digital voice assistant-delivered intervention, including osteoporosis-related nutrition information, resulted in small increases in the consumption of low-fat milk and eggs, but did not increase habitual protein or calcium intake in women with osteoporosis. Adequately powered trials are required to determine whether similar digital health interventions are effective for improving dietary behaviours in this population.
