Abstract

<p> This cross-sectional study aimed to elucidate the relationship between tongue pressure and nutrient intake in adults receiving home care services.</p><p> The study population consisted of 95 adults (mean age, 84.6 years) who received home care services covered by long-term care insurance. Tongue pressure was measured using a tongue pressure measurement device. A tongue pressure <20 kPa was defined as a low tongue pressure. Daily dietary intake of the following five nutrients was estimated using a brief-type self-administered diet history questionnaire: protein, vitamin D, vitamin E, vitamin C, and folate. According to the criteria proposed by a previous study or the Recommended Dietary Allowance (RDA) / the Adequate Intake (AI) proposed by the Dietary Reference Intakes for Japanese (2015), the above five nutrients were scored as low (1 point) or acceptable (0 point). The sum of the individual scores (0–5 points) gave the quantity of nutrients with levels below the proposed criteria. Using this score as an outcome, the association between tongue pressure and nutrient intake was estimated by Poisson regression analysis.</p><p> A low tongue pressure was found to be significantly associated with nutrient levels below the proposed criteria (rate ratio = 1.8, 95% confidence interval = 1.2–2.7 for the criteria proposed by the previous study; rate ratio = 1.7, 95% confidence interval = 1.2–2.5 for the RDA or AI criteria).</p><p> These findings suggest that low tongue pressure results in insufficient nutrient intake in adults receiving home care services.</p>
