Eating experiences in people living with dementia: A concept analysis using Rodgers's methodology.

AIMS: To analyse the concept of eating experiences in people living with dementia. DESIGN: Rodgers' evolutionary method of concept analysis was used as a framework for the paper. DATA SOURCES: The literature was searched using electronic databases PubMed, Google Scholar, CINHAL, PsycInfo, Web of Science, Embase and Elsevier databases. These databases cover a variety of disciplines, including but not limited to nursing, medicine and occupational therapy. The relevant literature published from 1989 to April 2023 was thoroughly examined. Any quantitative or qualitative studies published in English focused on eating or dining experiences in people with dementia were included. REVIEW METHODS: Rodgers' evolutionary method for concept analysis was used. The attributes, antecedents, consequences and case examples of the concept were identified. RESULTS: Twenty-two articles met the inclusion criteria, identifying key attributes of self-connection, the special journey of life and self-interpretation. Antecedents, as framed by the socio-ecological model, were categorized to represent intrapersonal (personal preferences, individual culture, mealtime routines), interpersonal (social interaction) and environmental (dining room environment, policies) factors. Consequences were divided into external (nutritional health, physical health and quality of life) and internal (personhood, autonomy and independence, dignity and feeling valued and mental well-being) domains. CONCLUSION: A theoretical definition and conceptual model of eating experiences in people living with dementia was developed. The identified attributes, antecedents and consequences can be utilized in nursing education, research and intervention approaches. IMPACT: This article allows nurses and other healthcare professionals to better understand people living with dementia through the relationship between eating and interpersonal, intrapersonal and environmental aspects to develop personalized interventions and care strategies to achieve an optimal quality of life.

A Mobile-Based Nutrition Tracker App Enhanced Dietitian-Guided 2:1:1 Diet-Induced Weight Loss: An 8-Week Retrospective Cohort Study in Taiwan.

Effective weight management interventions involve a combination of behavioral strategies focusing on dietary changes. Tracing the change through mobile apps has been proven to be a valuable platform for facilitating weight management in many countries. However, the effectiveness of mobile app-based dietary intervention on weight management in Taiwan remains to be determined. By using the designated mobile app, this study aimed to assess the efficacy of the diet intervention, which is based on a 2:1:1 portion control plate and a flexible low-carbohydrate (FLC) diet. This 8-week retrospective cohort study involved 10,297 participants who were divided into two groups: the intervention group (joined an 8-week diet intervention program with the daily diet record assessed by registered dietitians) and the control group (voluntarily using the app without instructional materials or coaching). After eight weeks of intervention, the intervention group showed a higher weight loss percentage (-4.78% vs. -1.54%), body mass index (BMI) (-1.26 kg/m2 vs. 0.69 kg/m2), and diet record completeness (73.52% vs. 28.91%) compared with the control group. With respect to gender, male participants showed higher baseline weight and higher weight loss (-6.02%) in the intervention group. In the intervention group, 2871 participants (33.4%) lost less than 4% of their weight, 5071 participants (58.9%) lost 4-8% of their body weight, and 662 participants (7.7%) lost >8% of their weight. Compared to the low-effectiveness group (weight lost <4%), the high-effectiveness group (weight lost >8%) had a significantly higher diet record completeness (91.61 ± 15.99 vs. 55.81 ± 32.92), dietary compliance (green light %) (88.93 ± 9.9 vs. 77.75 ±17.5), protein intake % (26.34 ± 2.85 vs. 23.49 ± 3.56), and fat intake % (49.66 ± 6.36 vs. 44.05 ± 7.37). Most importantly, the high-effectiveness group had a lower carbohydrate intake % (24.1 ± 7.86 vs. 32.46 ± 9.61). The results remained significant after being stratified by gender. This study found that the use of online applications plus the intervention of dietitians is beneficial for short-term weight loss. The composition of nutrients and dietary compliance also significantly impacted weight loss.
