Evaluation of buccal smear as an indicator of nutritional status

Area of Science:

• Pediatric Nutrition
• Cellular Biology

Background:

• Undernutrition affects child development globally.
• Early indicators of nutritional status are crucial for timely intervention.

Purpose of the Study:

• To investigate the correlation between buccal smear findings and the degree of undernutrition in children.
• To determine the diagnostic value of buccal smears for assessing childhood malnutrition.

Main Methods:

• A comparative study involving 148 healthy and 152 undernourished children.
• Analysis of buccal smears to identify cellular changes, specifically retrograde changes.
• Classification of children based on the severity of undernutrition.

Main Results:

• Undernourished children exhibited a higher frequency of retrograde changes in buccal smears compared to healthy children.
• However, the proportion of children without any retrograde changes was consistent across different nutritional status groups.
• The presence or absence of retrograde changes did not strongly differentiate nutritional levels.

Conclusions:

• Buccal smear analysis, particularly for retrograde changes, is not a dependable diagnostic indicator of undernutrition in children.
• Further research may be needed to identify more reliable and accessible biomarkers for childhood malnutrition.
• Clinical assessment remains paramount in diagnosing and managing undernutrition.
