Nutritional Risk in Community-dwelling Older Men: The Manitoba Follow-up Study

Abstract

Purpose: The role of nutrition in older men’s health and successful aging has been inadequately studied. We examined the relationships among nutritional risk, self-rated health, and successful aging in community-dwelling Canadian older men.
Methods: The surviving cohort of the Manitoba Follow-up Study (n=690, mean age = 86.8 years) were sent a selfadministered nutrition survey in December 2007. The survey consisted of the Seniors in the Community: Risk Evaluation for Eating and Nutrition, version II (SCREEN II), a validated tool for assessing nutritional risk of cognitively intact community-living older adults, and questions about successful aging and health.
Results: Of the 553 surveys returned (80% response), 522 with complete SCREEN II data were included in the analysis. Forty-four percent of respondents were at high nutritional risk, 24% were at moderate risk, and 32% were at low risk. Significant relationships were found between nutritional risk and self-rated health (P<0.0001) and successful aging (P=0.008), with greater nutritional risk associated with lower self-ratings of health and successful aging. Higher use of prescription medication was related to greater nutritional risk (P=0.004).
Conclusions: Nutritional screening programs for communitydwelling older men are warranted as two-thirds of the study participants were at nutritional risk. Identifying older men at nutritional risk is a critical step in the process of nutritional assessment, and subsequent nutrition interventions and followup are required to prevent further health decline.

Résumé

Objectif: Le rôle de la nutrition dans la santé et le vieillissement sain des hommes âgés n’a pas été étudié adéquatement. Nous avons examiné les liens entre le risque nutritionnel, l’état de santé autoévalué et le vieillissement sain chez des hommes canadiens âgés vivant dans la communauté.
Méthodes: Les membres encore en vie de la Manitoba Followup Study [étude de suivi du Manitoba] (n = 690, âge moyen = 86,8 ans) ont reçu un sondage autogéré sur la nutrition en décembre 2007. Le sondage comprenait 1) le Seniors in the Community: Risk Evaluation for Eating and Nutrition [Aînés dans la communauté: évaluation du risque nutritionnel], version II (SCREEN II), un outil validé servant à évaluer le risque nutritionnel d’adultes âgés sans troubles cognitifs vivant dans la communauté et 2) des questions sur le vieillissement sain et la santé.
Résultats: Des 553 sondages retournés (taux de réponse de 80%), les 522 comprenant la totalité des données SCREEN II ont été inclus dans l’analyse. Quarante-quatre pour cent des répondants présentaient un risque nutritionnel élevé, 24%, un risque modéré et 32%, un risque faible. Une relation significative a été établie entre le risque nutritionnel et l’état de santé autoévalué (p < 0,0001) et le vieillissement sain (p = 0,008), et le risque nutritionnel le plus élevé était associé à une autoévaluation moindre de l’état de santé et du vieillissement sain. Par ailleurs, une utilisation accrue de médicaments sur ordonnance était liée à un risque nutritionnel plus élevé (p = 0,004).
Conclusions: Il serait justifié de mettre en place des programmes de dépistage nutritionnel à l’intention des hommes âgés vivant dans la communauté puisque les deux tiers des participants à l’étude présentaient un risque nutritionnel. Identifier les hommes âgés présentant un risque nutritionnel est une étape critique du processus de l’évaluation nutritionnelle. De plus, des interventions nutritionnelles subséquentes et des suivis sont nécessaires afin de prévenir une détérioration additionnelle de la santé.
