Aims: Intrauterine growth is a relevant component of the window of opportunity for health promotion comprising the first 1,000 days of life. The present analysis describes fetal biometrical parameters according to international standards and their associations with maternal sociodemographic characteristics.
Methods: 481 women attending primary healthcare units in the urban area of Cruzeiro do Sul, Acre state, Brazilian Amazon, contributed with an ultrasound examination during their second trimester of pregnancy. Z scores by gestational age were calculated for fetal head circumference (HC), abdominal circumference (AC), and femur length (FL), according to the Intergrowth-21st Project standards. Each parameter was categorized into <–1 or ≥–1 Z for estimating prevalence ratios (PR) and 95%CI with Poisson regression models adjusted for maternal age, skin color, education, and parity.
Results: Mean (SD) gestational age at the ultrasound examination was 20.5 (2.8) weeks. Participants were 25.1 (6.4) years old, 81.1% brown/black, 23.3% had <9 years of education, and 43.0% were in their first pregnancy. Mean Z scores of biometric parameters were HC: –0.52 (0.75), AC: –0.10 (1.23), and FL: –0.21 (0.81). HC, AC, and FL were <–1 Z among 26.2%, 24.1% and 16.0% of the fetuses. In adjusted models, AC and FL <–1 Z were associated, respectively, with non-brown/non-black mothers (PR 1.51; 95%CI: 1.07, 2.14) and being in the first pregnancy (PR 2.10; 95%CI: 1.23, 3.45).
Conclusions: Maternal skin color and parity were factors associated with lower AC and FL Z scores in the second trimester according to international fetal growth standards.
