Association between maternal aflatoxin exposure during pregnancy and adverse birth outcomes in Uganda

Publication Type

Aflatoxins are toxic metabolites of Aspergillus molds and are widespread in the food supply, particularly in low‐ and middle‐income countries (LMICs). Both in utero and infant exposure to aflatoxin B1 (AFB1) have been linked to poor child growth and development. The objective of this prospective cohort study was to investigate the association between maternal aflatoxin exposure during pregnancy and adverse birth outcomes, primarily lower birth weight, in a sample of 220 mother‐infant pairs in Mukono district, Uganda.

HIV-Infected Pregnant and Lactating Women have Higher Serum Aflatoxin levels than HIV-Uninfected Women and Aflatoxin Levels are Higher during Early Postpartum than during Pregnancy among HIV-Infected Women

Publication Type

Aflatoxins are carcinogenic and may affect linear growth. Prior cross-sectional data from Ghana have shown that aflatoxin levels are ~ 20% higher among HIV-infected than HIV-uninfected post-partum women. It is not known if HIV-infected pregnant women have elevated serum aflatoxin levels during pregnancy, or if aflatoxin levels change during the perinatal period. We therefore studied these relationships among a cohort of 246 women recruited in Gulu, Uganda, and followed through pregnancy and early infant life.

Perinatal Exposure to Aflatoxins is Associated with a Lower Rate of Weight Gain Among HIV-Infected Pregnant Women and Reduced Linear Growth of HIV-Exposed Infants

Publication Type

Aflatoxins (AF) are carcinogens associated with poor linear growth in infants. AF serum levels have been reported to be higher in HIV infected (+) women. However, it is not known if maternal AF exposure affects gestational weight gain (GWG), or if relationship between in utero AF exposure and changes in perinatal anthropometry differs by maternal HIV or infant HIV exposure status. We enrolled 403 pregnant women (33.3% HIV (+), all on anti-retroviral treatment) at the antenatal clinic of Gulu Hospital, northern Uganda.
