Study Notes
Nutritional Assessment
- Nutritional status is influenced by food intake quality and quantity, and also by individual health.
- Nutritional assessment aims to identify nutritional problems, populations needing assistance, and evaluate the success of programs.
- Assessment targets children (preschool and school-age) and broader community needs.
- Representative sampling is sufficient; not everyone needs to be examined.
Objectives of Nutritional Assessment
- Identify community nutritional problems.
- Identify high-risk populations needing help.
- Design nutrition programs tailored to identified needs.
- Evaluate the effectiveness of nutrition programs.
- Assess malnutrition severity in children.
Methods of Nutritional Assessment
- A multifaceted approach is necessary to evaluate various stages of nutritional diseases.
Clinical Examination
- Essential for all nutritional surveys.
- It is a practical way to check nutritional status.
- Physical signs, specific and non-specific, offer valuable insights.
- Presence of multiple deficiency signs greatly enhances diagnosis.
- Signs to be evaluated include things unrelated to nutrition (alopecia, pyorrhaea, pterygium) things needing further evaluation (molar pigmentation, vascularization, geographic tongue) and specific indications (angular stomatitis, Bitot's spot, calf tenderness, beriberi, goiter).
Anthropometry
- Measures physical attributes like height, weight, head circumference, skinfold thickness, arm circumference, waist circumference.
- Track children's growth using height/length-for-age and weight/length charts.
- Specific tools include infant meters, measuring rods, stadiometers, and road to health cards.
- Skinfold thickness measurement assesses body fat using calipers.
- Waist circumference measurement (above 40 inches for men, 35 inches for women) indicates potential disease risk.
- Mid-arm circumference (MAC) is essential for growing and malnourished children.
- Head circumference is primarily for children under 3, and indicates potential non-nutritional issues.
Laboratory and Biochemical Assessment
- Hemoglobin estimation is crucial for overall nutritional status.
- Stool and urine tests used to identify intestinal parasites or other health issues.
- Biochemical tests (e.g., serum retinol, serum iron) and urine analysis (iodine) detect nutrient levels and abnormalities. – These are more time-consuming and costly than other methods, so are mainly used for specific instances.
- Dietary history, chronic dysentery, and diarrhea provide helpful information.
Assessment of Dietary Intake
- Direct assessment of food consumption through dietary surveys, either household-level or individual.
- Dietary surveys can use different methods: weighing raw or cooked foods and/or oral questionnaires. Individual responses or household-level studies are possible.
