Study Notes
### What is Nutritional Assessment?
- Nutritional assessment is the very first step in the Nutrition Care Process
- The process involves gathering, analyzing and interpreting information to understand if a person or group is well-nourished or malnourished
- Data can come directly from individuals through interviews, observations, and measurements
- Data for populations is gathered from surveys, epidemiological and research studies
Data Collection for Nutritional Assessment
- The data gathered for nutritional assessment depends on the setting where it's being performed
Nutritional Assessment Applications
- Assessment is used in schools to identify students needing supplementary feeding
- The military uses it to identify those 'fit' for service
- It's now a common practice in both community and clinical settings
### Nutritional Assessment Methods
- Nutritional assessments can be direct or indirect
- Direct methods use body dimensions, nutrient tissue or fluid concentrations, dietary intake, and clinical signs of nutritional deprivation (ABCDS)
### Direct Nutritional Assessment (ABCDS) Methods
- A= Anthropometry: Measuring body dimensions and proportions
- B= Biochemical/Biophysical: Assessing nutrient levels in body fluids, tissues, and excreta
- C= Clinical: Observing the signs and symptoms related to nutritional deficiencies
- D= Dietary: Determining dietary intake through interviews, food records, and dietary analysis
Indirect Methods of Nutritional Assessment (Ecological)
- Indirect methods assess food and nutrition situations in a specific area
- They use data related to malnutrition or that are aggravated by malnutrition
- These include:
- Cause-specific mortality rates
- Age-specific mortality rates
- Health service statistics
- Rates of nutritionally relevant infections
- Meteorological data, such as rainfall
- Production patterns and distribution patterns
- Income levels
- Food market prices
- Prevalence of cash crops
Anthropometric Assessments
- Anthropometry literally means "the measurement of humans"
- Anthropometric measurements can be used in both clinical and field settings
- It is the assessment of physical dimensions and body composition
- Anthropometric measurements can be used to assess:
- Post-operative patients
- Chronically sick medical patients
- Severely malnourished patients
- To assess the impact of nutritional interventions
### Purposes of Anthropometric Measurements
- Children: To assess physical growth
- Adults: To assess changes in body composition or weight
### Anthropometric Measurements of Growth
- Growth is a key indicator of nutritional status in children
- Children's growth performance often reflects underlying nutritional problems
- Chronic nutritional deficits can lead to reduced growth rates or a complete cessation of growth
### Child Growth
- Growing children are healthy children
- Optimal growth requires adequate food, absence of illness, caring environment, and social support
- The most rapid growth period is the first year of life
- Weight and height are commonly used to measure growth
- Weight gain is one of the most accurate and sensitive measures of growth
### Head Circumference (HC)
- Head circumference is measured with a flexible measuring tape to the nearest millimeter
- The tape is placed around the head, measuring the supra-orbital ridge anteriorly and the occipital prominence posteriorly
- HC is useful for assessing chronic nutritional problems in children under two
- After two years it is less reliable because brain growth slows down significantly
Length
- Length is measured in a supine position using a measuring board
- It is used to determine physical growth in children under two
- Height is used for children over two years old
- Length and height are important for tracking growth and identifying growth problems
