Brief Summary
This research study research is about the significance of polyunsaturated fatty acids (PUFAs) for human development. Specifically, the study team will assess the effect of docosahexanoic acid (DHA) supplementation during pregnancy on infant growth and development through a randomized controlled intervention trial in Cuernavaca, Mexico. This is a collaborative effort between the Rollins School of Public Health, Emory University, the Instituto Nacional de Salud Publica (INSP) and the Instituto Mexicano del Seguro Social (IMSS), Cuernavaca, Mexico. Pregnant women attending the IMSS General Hospital I are recruited between 18-22 weeks gestation and assigned randomly to receive either DHA (400 mg) or a placebo daily until delivery. The main study outcomes include a) birth outcomes: birth size, gestational age, cord blood levels of DHA and neurodevelopment b) maternal blood and breast milk DHA levels at 1 and 3 months post-partum, c) postnatal growth and development during the first 5 years of age and d) infant DHA status at 3, 12 and 18 months.

Outcome Measures
Primary Outcomes (9)
Birth size
Birth size will be determined by measuring the newborn, a baby's length is measured from the top of their head to the bottom of one of their heels.
Birth
Gestational age
Gestational age is measured in weeks, from the first day of the woman's last menstrual cycle to the current date.
Birth
Changes in visual evoked potentials
Visual evoked potential (VEP) is an electrical signal emanated from the brain while a visual stimulus is presented to the subject in a time locked manner. The VEP can be used as a diagnostic tool to detect ocular diseases in patients with visually impaired. VEP response can also be used to detect eye diseases like glaucoma, diabetic retinopathy, multiple sclerosis, ocular hypertension, loss of peripheral (side) vision, macular degeneration and color blindness.
3 and 6 months of age
Changes in infant weight
Infant weight is measured in kilograms (kg) and weight is measured in the hospital and at all check-ups.
Birth, months 1, 3, 6, 9, 12, 18, 24, 36 and at 4 and 5 years of age
Changes in infant height
Infants will be measured in the hospital and at all check-ups. Height is measured in centimeters (cm).
Birth, months 1, 3, 6, 9, 12, 18, 24, 36 and at 4 and 5 years of age
Changes In infant head circumference
Head circumference or OFC \[occipital frontal circumference\] is measured over the most prominent part on the back of the head (occiput) and just above the eyebrows (supraorbital ridges). This can be translated to mean the largest circumference of the head. Head circumference is measured in centimeters (cm).
Birth, months 1, 3, 6, 9, 12, 18, 24, 36 and at 4 and 5 years of age
Changes in auditory evoked potentials
A brainstem auditory evoked response (BAER) test measures how the brain processes the sounds a person hears. The BAER test records the subject's brainwaves in response to clicks or other audio tones that are played for them.
1 and 3 months of age
Changes in child development score
The Bayley Scales of Infant Development -II are used to assess child development during the first two years of life while The McCarthy Scales of Children's Abilities (MSCA) is a psychological instrument for young children that measures cognitive ability in six domain areas: Verbal, Perceptual-Performance, Quantitative, General Cognitive, Memory, and Motor at age 5 y.
1, 1.5 and 5 years of age
Changes in Hearts and Flowers Stroop Test
This tests working memory, response inhibition, and task switching/cognitive flexibility . The task requires participants to press a response button that is either on the same side (congruent) or opposite side (incongruent) of an image. When children see an image of a heart, they are instructed to press the corresponding directional arrow button on a keyboard. When children see an image of a flower, they are instructed to press the opposite directional arrow button on the keyboard . The task consists of three separate levels that contain only congruent trials (12 trials total), only incongruent trials (12 trials total), and mixed congruent and incongruent trials respectively (33 trials total). Images are presented on a computer monitor. Before both the congruent and incongruent trial blocks, a training period is administered which consists of 5 trials. The child is unable to advance to the next question until they respond correctly.
5 years of age
