BACKGROUND: Malnutrition is associated with comorbidities and functional decline among older people. Less is known about nutrient intakes across heterogeneous older populations.
OBJECTIVE: We examined nutritional status and nutrient intakes in different samples of older people representing broad spectrum of healthy and frail populations. We evaluated adequacy of their energy, protein and micronutrient intakes in comparison to recommendations.
DESIGN AND PARTICIPANTS: Cross-sectional study combined five datasets: home-dwelling older people participating in nutrition education and cooking classes (NC) [n=54], participants from Helsinki Businessmen Study [n=68], home-dwelling people with Alzheimer disease (AD) [n=99] and their spousal caregivers (n=97), participants from Porvoo Sarcopenia and Nutrition Trial (n=208), and residents of Helsinki assisted living facilities (ALF) [n=374]. Nutritional status was assessed using Mini Nutritional Assessment and nutrient intakes retrieved from 1 to 3 day food records.
RESULTS: Those suffering most from mobility limitation and cognitive decline had the poorest nutritional status (p<0.001; adjusted for age, sex, comorbidities). However, low intakes of energy, protein, and micronutrients were observed in high proportion in all groups, inadequate intakes of vitamins D, E, folate, and thiamine being most common. Protein intakes did not differ between the groups, but 77% of all participants had lower than recommended protein intake. In general, the NC group had highest micronutrient intakes and the ALF group the lowest. However, AD females had the lowest energy, protein, and vitamin C intakes.
CONCLUSIONS: Our study provides a detailed picture of risks related to nutrient intakes in various groups of older people. These findings could be used in planning tailored nutrition interventions.
