Cross-sectional but not Longitudinal Measures of Food Insecurity are Associated with the Rate of Weight Gain during Pregnancy in Northern Uganda

Food insecurity (FI) during pregnancy may lead to adverse health outcomes for affected women. However, little is known on whether such effects are due to short-term within person changes (longitudinal effects) in FI or long-term between person differences (cross-sectional effects) in this exposure. Therefore, the aim of this study was to assess whether differences in cross-sectional measures of FI between women (defined as the mean prenatal IFIAS score) and/or longitudinal changes in FI within women

Progression of antepartum depression differs by level of perceived social support and food insecurity

Antepartum depression (AD) is a risk factor for adverse pregnancy outcomes and may be worsened by food insecurity (FI) and lack of social support (SS). We studied the progression of AD from mid gestation to term and examined whether such progression differed by measures of SS and longitudinal measures of FI

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

Published: April 2016 Authors: Barnabas Natamba, Jia-Sheng Wang, Sera Young, Shibani Ghosh, Jeffrey Griffiths Publisher: FASEB
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.

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

Published: April 2016 Authors: Barnabas Natamba, Shibani Ghosh, Jeffrey Griffiths Publisher: FASEB
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. All HIV-positive women received HIV antiretroviral therapy for free from Continue reading →

Building Strategic Capacities to Strengthen the Enabling Environment for Nutrition Policies and Programs in Four African Countries

Published: August 2015 Authors: David Pelletier, Barnabas Natamba, Dia Sanou, Jackson Tumwine Publisher: European Journal of Nutrition and Food Safety
Undernutrition has received significant attention at global and national levels in recent years but translating this attention into effective action at the country and district levels poses many challenges. We describe the observed national environments that support and challenge actors in moving national multisectoral nutrition policies and plans forward and how this on-going action research (AR) project seeks to strengthen strategic capacities and leadership in Burkina Faso, Mali, Ethiopia and Uganda.

Alcohol Use Among Pregnant Ugandan Women of Mixed HIV Status is Associated with Social Environment and Food Insecurity

Published: July 2015 Authors: Shalean Collins, Barnabas Natamba, Angela Arbach, Elizabeth Widen, Pooja Desai, Hijab Khan, Jeffrey Griffiths, Sera Young Publisher: FASEB
Antenatal alcohol use (AAU) is associated with poor health outcomes in maternal-infant dyads. However, AAU prevalence and risk factors are poorly understood, particularly in low-income settings. Therefore we studied correlates of any AAU among pregnant women receiving antenatal care in Gulu, Uganda.
