High Intake of Nonmilk Extrinsic Sugars Is Associated With Protein and Micronutrient Dilution in Home-Dwelling and Institutionalized Older People.

BACKGROUND: High dietary sugar intake may compromise protein and micronutrient intakes in people with low energy intakes. The results of micronutrient dilution studies in older people have been few and conflicting. We examined the nutritional status and nutrient intakes associated with nonmilk extrinsic sugars (NMES) intakes in older people representing a broad spectrum of both healthy and vulnerable older populations.

DESIGN AND PARTICIPANTS: This cross-sectional study combined five Finnish data sets covering home-dwelling (n = 526) and institutionalized (n = 374) older people. Their nutritional status was assessed using Mini Nutritional Assessment (MNA) and nutrient intakes retrieved from 1- to 3-day food records. The participants were divided into quartiles corresponding to the proportions of energy received from NMES. Energy, nutrient, and fiber intakes were classified according to the NMES quartiles, and the participants were divided according to their places of residence (home, institution).

RESULTS: High NMES intakes were associated with older age, female sex, poor cognition, low MNA scores, immobility, and institutionalization. In all, 90% of the participants in the highest NMES quartile (Q4) were institutionalized. In the institutionalized individuals, low protein and micronutrient intakes were observed in both those with low energy intake (Q1) and in those with very high NMES intakes (Q4). In home-dwelling individuals, the nutrient intakes tended to decline linearly with increasing NMES intakes in protein and most micronutrients.

CONCLUSIONS: Institutionalized older people consumed diets high in NMES, compared with those living at home, and their low energy and high NMES intakes were associated with low protein and micronutrient intakes.
