Study Notes

Assessment of Nutritional Status

Assessing nutritional status helps identify nutritional disorders, plan corrective measures, and evaluate the effectiveness of strategies.

Levels of Nutritional Assessment

Physical and physiological measurements: Include weight, height, body composition analysis (including body fat and arm muscle area), and blood pressure.
Laboratory (biochemical): Involves examining serum proteins (albumin, transferrin, prealbumin, retinol binding protein), immune markers (total leukocyte count, lymphocyte count), iron status (serum ferritin, serum iron, haemoglobin (Hb), haematocrit, mean corpuscular volume (MCV)), calcium and vitamin A status, and iodine status (serum level of thyroxine (T4)).
Physical examination (observation): Focuses on general appearance (skin, hair, nails, angles of the mouth, tongue, mucous membranes, eyes, joints, feet), and evidence of weight gain or loss. Palpation checks skin, skin folds, hair, eyes, mouth, mucous membranes, abdomen, skeletal structure, chest, pulse, and any swellings. Auscultation involves listening to chest, heart, and abdominal sounds.
Dietary and personal history: Includes diet history, 24-hour recall, food record diary, food frequency, sources and methods of food preparation, eating habits, and eating patterns.

Nutrition

Undernutrition and micronutrient deficiencies significantly impact global health.
Undernutrition and infectious diseases are interconnected and exacerbate poverty by reducing earning potential due to lost wages, increased healthcare costs, and impaired intellectual development.

Growth Monitoring

Factors influencing growth: Family genes, adequate nutrition, infectious diseases, endocrine hormones (growth hormone, pituitary), systemic diseases (diabetes), stress, abuse, effects of race/ethnicity/genetics versus nutrition/attitude, and environment.
Anthropometric indicators for growth monitoring:
- Weight-for-age: Good for assessing acute and chronic malnutrition, sensitive to small changes, objective and repeatable, easy for inexperienced health workers, not time-consuming. Disadvantages include not being sensitive to stunted children who are growing well or very tall children who may be malnourished.
- Length/Height-for-age: Good indicator of past nutrition problems, objective, repeatable, requires different techniques depending on age. Disadvantages are that changes occur slowly, need multiple techniques if including all preschoolers, and difficult for unskilled workers.
- Weight-for-length/height: Useful for distinguishing well-proportioned from thin/heavy individuals based on height, objective and repeatable. disadvantages include that weight-for-height can underestimate malnutrition if cut-offs aren't adjusted, it takes more time and training to weigh and measure, and inexperienced workers may not use it consistently.
Z-scores: Used to categorize growth based on the standard deviation. Categories include: above 3 (excellent), above 2 (good), above 1 (median), below -1, below -2 (stunted), below -3 (severely stunted), obese, overweight, underweight and wasted.
Interpreting growth trends: Observe if a child's growth line crosses a z-score line, shows a sharp incline or decline, or is flat/stagnant.
