Nutrition Education with or Without Oral Nutrition Supplements Has Contrasting Effects on Nutrition Status in Older Adults: A Randomized Controlled Study

BACKGROUND:Oral nutrition supplements (ONSs) play an important role in the management of malnutrition. This aim of study was to examine whether a comprehensive intervention, combining ONSs, family-centered health education, and nutrition and medical consultations, could improve the nutrition and health status of malnourished older adults living in community dwellings.METHODS:A randomized controlled trial was conducted from October 2017 to May 2018 in Shanghai. All participants were screened using the Mini Nutritional Assessment-Short Form (MNA-SF). Participants with MNA-SF scores ≤11 and age ≥65 were selected. Participants with potential nutrition risk were randomized into two groups: intervention group (n = 101) were prescribed ONSs (400 kcal/day) and family-centered nutrition education (once every 2 weeks) and control group (n = 100) received only family-centered nutrition education. Anthropometric measurements, including weight and height, and nutrition and functional scales, including MNA-SF, grip strength, and activities of daily living scores, were collected at the beginning of the study and 12 weeks later.RESULTS:Of the 201 study participants, 182 completed the study (mean age, 75.48 ± 7.47 years). After 12 weeks, nutrient intake improvements in the intervention group (+370.6 ± 432.6 kcal/day, +17.6 ± 24.1 g/day) exceeded that of the control group (-67.5 ± 378.2 kcal/day, -0.9 ± 16.7 g/day). In addition, improvements in weight, body mass index, and handgrip strength were significantly higher in the intervention vs control group (P < .05).CONCLUSION:Comprehensive nutrition interventions improved nutrition status in malnourished older people living in community dwellings. Use of ONSs may be a good strategy to improve nutrition status and strength in community-dwelling older adults.
