Summary
Malnutrition affects 35% of stroke patients early after rehabilitation, with improvements seen by 6 months. Nutritional status, particularly serum proteins and body fat, impacts recovery and outcomes in stroke survivors.
Area of Science:
- Geriatric Medicine
- Neurology
- Nutritional Science
Background:
- Nutritional status in stroke patients is under-researched, especially during late-stage home rehabilitation.
- Previous estimates indicate 15-20% malnutrition in the acute stroke phase.
- Attention to nutrition may decrease in the home environment during stroke recovery.
Purpose of the Study:
- To determine the prevalence of malnutrition in stroke patients during 6 months of rehabilitation.
- To investigate the association between nutritional status and functional recovery.
- To explore the link between nutritional status, hospital stay length, and infectious complications.
Main Methods:
- 89 ischemic stroke patients were evaluated for nutritional status at 1 week, 5 weeks, 3 months, and 6 months post-stroke.
- Nutritional assessment included body weight, BMI, MAC, TSF, serum albumin, and transferrin.
- Malnutrition was defined by two or more abnormal nutritional variables.
Main Results:
- Albumin levels significantly increased from 1 week to 6 months (P < 0.0001).
- Transferrin levels significantly increased from 5 weeks to 6 months (P < 0.05).
- Malnutrition prevalence decreased from 35% at 1 week to 22% at 6 months.
Conclusions:
- 35% of elderly ischemic stroke patients exhibited malnutrition 1 week post-stroke, affecting serum proteins and body fat.
- Nutritional status showed improvement over 6 months of rehabilitation.
- 22% of patients remained malnourished at the 6-month follow-up point.

Nursing management for a patient with arteriosclerosis involves a comprehensive approach focusing on lifestyle modification, disease monitoring, education, and symptomatic care. Here is an overview of effective nursing strategies:Assessment and Monitoring: Initial and ongoing assessments are crucial. Nurses must document the patient's medical history, including any hypertension, diabetes, hyperlipidemia, and other cardiovascular diseases. Assessments also cover family history and lifestyle...
