Insights
Peruvian infants showed lower stunting rates than expected, with growth influenced by factors like age, sex, birth measurements, breastfeeding, and maternal origin altitude.
Area of Science:
- Pediatric Growth and Development
- Human Nutrition
- Anthropometry
Background:
- Previous Peruvian child growth studies indicated high stunting rates.
- Limited data existed on Peruvian infant body composition.
Purpose of the Study:
- Characterize anthropometric measures in Peruvian infants (0-12 months).
- Compare infant measures against international growth references.
- Identify biological, environmental, and socioeconomic influences on infant growth.
Main Methods:
- Longitudinal study of 232 infants in Lima, Peru (1995-1997).
- Collected anthropometric data from mothers and infants from birth to 12 months.
- Conducted weekly morbidity and dietary intake surveillance during the second half of infancy.
Main Results:
- Stunting, underweight, and wasting prevalence were below 4% using WHO growth references.
- Infants of mothers from high-altitude regions exhibited larger chest circumference and length.
- Key growth predictors included age, sex, birth anthropometry, breastfeeding, maternal factors, primiparity, diarrhea prevalence, and maternal region altitude.
- Maternal education, asset ownership, sanitation, and hygiene were not associated with growth.
Conclusions:
- Peruvian infants in this urban cohort demonstrated lower-than-anticipated stunting rates.
- Proximal and familial factors significantly impacted infant growth throughout the first year.
Background:
Previous growth studies of Peruvian children have featured high stunting rates and limited information about body composition.
Objective:
We aimed to characterize anthropometric measures of Peruvian infants 0 to 12 months of age in relation to the international growth references and biological, environmental, and socioeconomic factors.
Methods:
Infants (n = 232) were followed longitudinally from birth through 12 months of age from a prenatal zinc supplementation trial conducted in Lima, Peru, between 1995 and 1997. Anthropometric measures of growth and body composition were obtained at enrollment from mothers and monthly through 1 year of age from infants. Weekly morbidity and dietary intake surveillance was carried out during the second half of infancy.
Results:
The prevalence rates of stunting, underweight, and wasting did not exceed 4% based on the World Health Organization growth references. Infants of mothers from high-altitude regions had larger chest circumference (p = .006) and greater length (p = .06) by 12 months. Significant predictors of growth and body composition throughout infancy were age, sex, anthropometric measurements at birth, breastfeeding, maternal anthropometric measurements, primiparity, prevalence of diarrhea among children, and the altitude of the region of maternal origin. No associations were found for maternal education, asset ownership, or sanitation and hygiene factors.
Conclusions:
Peruvian infants in this urban setting had lower rates of stunting than expected. Proximal and familial conditions influenced growth throughout infancy.
