Mealtimes in long-term care (LTC) homes provide social engagement and nutritional intake to residents. Psychosocial challenges may detract from the mealtime experience, resulting in low food intake and increased risk of malnutrition. This study explores the independent effects of psychosocial factors on energy intake among LTC residents. Secondary data (Making the Most of Mealtimes [M3]) from residents in 32 Canadian LTC homes were analyzed. Data included 3-day weighed food intake, mealtime care actions taken by staff, loss of appetite, eating challenges, and other resident characteristics. Psychosocial factors (i.e., social engagement, depression, and aggressive behaviours) were measured using standardized scales. The independent effects of psychosocial factors on energy intake were tested using bivariate and linear regression analyses adjusted for loss of appetite, eating challenges, and demographic characteristics. The final sample included 604 residents (mean age = 86.8 ± 7.8 years; 31.8% male). Of the three psychosocial factors, only social engagement was associated with energy intake. Low social engagement was associated with cognitive and functional challenges, malnutrition risk, more task-focused mealtime actions by staff, and lower energy intake. Simple regression analysis revealed that individuals with low social engagement ate 59.6 kcal less per day (95% CI = -111.2, -8.0). This significant association remained when adjusting for loss of appetite, but was no longer significant when adjusting for eating challenges. Low social engagement occurs concurrently with physical and functional challenges among LTC residents, affecting both the nutritional and social aspects of mealtimes. Emphasis on socializing during mealtimes, especially for those with eating challenges (e.g., requiring assistance), may contribute to improved resident appetite and quality of life.
疗养院的用餐时间为居民提供了社交机会和营养摄入。心理社会挑战可能会影响用餐体验,导致食物摄入量减少和营养不良风险增加。本研究探讨了心理社会因素对疗养院居民能量摄入的独立影响。对来自加拿大 32 家疗养院的 32 名居民的二级数据(充分利用用餐时间 [M3])进行了分析。数据包括 3 天的称重食物摄入量、员工采取的用餐时间护理措施、食欲不振、进食挑战以及其他居民特征。使用标准化量表测量心理社会因素(即社交参与度、抑郁和攻击性行为)。使用双变量和线性回归分析测试心理社会因素对能量摄入的独立影响,调整了食欲不振、进食挑战和人口统计学特征。最终样本包括 604 名居民(平均年龄 86.8 ± 7.8 岁;31.8%为男性)。在这三个心理社会因素中,只有社交参与度与能量摄入有关。社交参与度低与认知和功能挑战、营养不良风险、员工更多以任务为中心的用餐时间护理措施以及能量摄入较低有关。简单回归分析显示,社交参与度低的人每天少吃 59.6 卡路里(95%CI=-111.2,-8.0)。当调整食欲不振时,这种显著关联仍然存在,但当调整进食挑战时,这种关联不再显著。低社交参与度与疗养院居民的身体和功能挑战同时发生,影响用餐时间的营养和社交方面。在用餐时间强调社交,特别是对于那些有进食挑战的人(例如需要帮助),可能有助于改善居民的食欲和生活质量。
