Sugary Liquids in the Baby Bottle: Risk for Child Undernutrition and Severe Tooth Decay in Rural El Salvador

Area of Science:

• Public Health
• Pediatrics
• Nutrition Science

Background:

• Global dietary shifts towards processed foods and sugar-sweetened beverages (SSBs) exacerbate child obesity, tooth decay, and undernutrition in Latin America.
• Shared risk factors between child undernutrition and poor oral health require further investigation for effective interventions.
• Severe early childhood caries (sECC) and undernutrition present significant public health challenges in developing regions.

Purpose of the Study:

• To identify dietary, oral health, and sociodemographic risk factors for child undernutrition and sECC.
• To examine the relationship between undernutrition and sECC in Salvadoran children.
• To inform integrated health interventions for maternal and child well-being.

Main Methods:

• Convenience sample of 797 caregiver-child pairs from rural Salvadoran communities.
• Caregiver interviews collected data on child dietary and oral health practices.
• Child anthropometric measurements (height, weight) and dental examinations were performed.

Main Results:

• Caregiver use of SSBs in baby bottles was a significant risk factor for both child undernutrition (p = 0.011) and sECC (p = 0.047).
• Early childhood caries (p = 0.023) was identified as a risk factor for developing undernutrition.
• Multivariable regression analyses identified key associations between feeding practices and health outcomes.

Conclusions:

• Discouraging the use of SSBs in baby bottles is crucial for preventing undernutrition and sECC.
• Integrated maternal-child health, nutrition, and oral health programs are recommended.
• Policy advocacy to limit SSB marketing to young children and families is essential.
