Nutritional Status

• Good nutritional status is characterized by:
  • An alert and good-natured personality
  • A well-developed body with normal weight for height
  • Well-developed and firm muscles
  • Healthy skin with reddish-pink eyelids and oral membranes
  • Good appetite and excellent general health
  • Stamina for work, normal elimination, and resistance to disease

Nutritional Assessment

• The purpose of nutritional assessment is to:
  • Identify individuals or populations at risk of malnutrition
  • Identify individuals or populations who are malnourished
  • Develop healthcare programs that meet community needs based on assessment findings
  • Measure the effectiveness of nutritional programs

Methods of Nutritional Assessment

• Direct Methods:

  • Clinical Examination: Assess health levels in relation to food consumption. It is an essential part of nutritional surveys and helps identify malnutrition and micronutrient deficiencies.
  • Anthropometric Examination: Measures body height, weight, and proportions. Crucial for assessing infants, children, and pregnant women. It evaluates under and overnutrition, reflecting current nutritional status, but doesn't differentiate between acute and chronic changes.
  • Biochemical Examination: Includes initial and specific lab tests:
    • Initial Lab Tests:
      • Hemoglobin: Assessment is vital in nutritional surveys, acting as an index for overall nutrition and indicating protein and trace element levels.
      • Stool: Detects intestinal parasites.
      • Urine: Examines for albumin and sugar.
    • Specific Lab Tests:
      • Measuring individual nutrients in body fluids: (e.g., serum retinol, serum iron, urinary iodine, vitamin D)
      • Detecting abnormal metabolites in urine: (e.g., urinary creatinine/hydroxyproline ratio)
      • Analyzing hair, nails, and skin for micronutrients.
  • Dietary Examination: Supplements nutritional assessment by assessing food consumption. Methods include:
    • Recall: Usually a 24-hour recall, sometimes 3 days. It is straightforward, quick, and cost-effective for large samples. Limitations include relying on memory, kitchen/serving literacy, and not being suitable for children under 7 years old.
    • Food Frequency Questionnaire: Covers a longer period and isn't influenced by short-term changes. However, it reflects desire rather than reality, lacks precision, and is not suitable for children.

• Indirect Methods:

  • The Study of Vital Statistics: Involves mortality and morbidity data to identify high-risk groups and the extent of the risk within the community. Mortality data might not be sufficient, but morbidity data from hospitals or community health and morbidity surveys reveals insights into protein-energy malnutrition, anemia, and vitamin A deficiency.
  • Analysis of Ecological Factors: Collects background information on a community to provide a comprehensive assessment. Ecological factors related to malnutrition include:
    • Conditioning Influences: Bacterial, viral, and parasitic agents
    • Cultural Influences: Food habits, practices, cooking beliefs, child-rearing practices, feeding of pregnant or lactating mothers
    • Socio-economic Factors: Family size, occupation, education, income, housing, food expenditure

Nutrition Overview

• Definition of Food: Products derived from plants or animals that provide energy and nutrients for life, growth, and health. It encompasses anything eaten or drunk, meeting the body's needs for energy, building, regulation, and protection.
• Definition of Nutrition: The science that studies food and its effects on the body's health. It explores the processes of consuming, digesting, metabolizing, and storing nutrients, as well as their impact on the body. It also focuses on factors influencing eating patterns, providing dietary recommendations, maintaining food safety, and addressing global food supply issues.
• Diet: The foods and beverages a person consumes daily, encompassing habitual diets, group diets (e.g., hostel diets), and therapeutic diets for specific health conditions.
• Malnutrition: Results from a lack, excess, or imbalance of nutrients in the diet. It includes undernutrition and overnutrition.
  • Undernutrition: Insufficient supply of essential nutrients. It can be primary (due to insufficient supply) or secondary (resulting from metabolic errors, nutrient interactions, or drug interactions).
  • Overnutrition: Excessive intake of one or more nutrients, causing stress on bodily functions.

Assessment of Nutritional Status

• Nutritional status is the state of the body resulting from food intake and its utilization. It can be good, fair, or poor.
