Intrauterine growth of live-born Tanzanian infants
Insights
This study presents intrauterine growth curves for Tanzanian infants, revealing reduced fetal weight gain from 28-34 weeks but increased velocity later. Findings highlight differences compared to Caucasian standards, informing low birthweight infant research.
Area of Science:
- Obstetrics and Gynecology
- Pediatrics
- Public Health
Background:
- Low birthweight (LBW) is a significant global health concern.
- Intrauterine growth retardation (IUGR) impacts infant anthropometry and long-term health.
- Establishing local growth standards is crucial for accurate assessment.
Purpose of the Study:
- To establish local intrauterine growth curves for weight, length, and head circumference in Dar es Salaam, Tanzania.
- To analyze the effect of IUGR on anthropometric measurements in this population.
- To compare Tanzanian fetal growth patterns with Caucasian standards.
Main Methods:
- Development of intrauterine growth curves for weight, crown-heel length, and head circumference.
- Calculation of body measurement ratios (weight/length, weight/head circumference).
- Comparative analysis with established Caucasian growth standards.
Main Results:
- Reduced fetal weight gain observed between 28 and 34 weeks of gestation in Dar es Salaam.
- Fetal length and head circumference were less affected during this period.
- An increased intrauterine growth velocity was noted from 34 to 38 weeks of gestation.
Conclusions:
- Tanzanian fetal growth patterns differ from Caucasian standards, particularly in weight gain during mid-gestation.
- Local growth curves are essential for accurate diagnosis and management of IUGR in Dar es Salaam.
- Findings underscore the impact of socio-economic and nutritional factors on fetal development.
Abstract:
The incidence of low birthweight infants, the effect of intrauterine growth retardation on anthropometric measurements, and local standards of intrauterine growth curves for weight, crown-heel length and head circumference together with curves of body measurement ratios of weight/length, weight/head circumference and weight/length x head circumference are presented for the population of Dar es Salaam (Tanzania). Acomparison is made with a standard composed for a Caucasian community with completely different socio-economic and nutritional status. From 28 to 34 weeks of gestation weight gain in Dar es Salaam foetuses was reduced, while length and head circumference were relatively less affected. However, an increased intrauterine growth velocity was recorded from 34 to 38 weeks of gestation.
