Impact of Maternal Stress on Infant Stunting

Status Completed

Clinical Trial Summary

This study takes place in rural Mam-Mayan communities of Guatemala characterized by high rates of childhood stunting. It aims to characterize women's exposure to nutrition, infection and psychosocial stressors vs. resilience factors, to evaluate the cumulative impact of maternal-level factors (nutritional, infectious, psychosocial), social factors (autonomy, social support, domestic violence), and household factors (socioeconomic status, food security) on early infant growth, and to evaluate whether maternal cortisol may be a mediator in the vertical transmission of stress.

Clinical Trial Description

Grounded in participatory action research and a socio-ecological framework, this mixed-methods, observational study enrolled a longitudinal cohort of 155 women, seen during pregnancy (6-9 mo), early (0-6 wks) and later (4-6 mo) postpartum, and two cross-sectional cohorts (60 early, 56 later postpartum).

Maternal and infant anthropometry was recorded, maternal fecal, urine and saliva samples were collected, and questionnaires were used to explore household factors (socioeconomic status, food security), social factors (autonomy, paternal/social support, domestic violence), and maternal-level factors (nutrition, infection, emotional distress).

Analyses focused on (1) characterizing women's exposure to nutrition, infection and psychosocial stressors vs. resilience factors, (2) describing the maternal diurnal salivary cortisol rhythm in pregnancy and postpartum and explore its association with psychosocial variables, (3) assessing the cumulative impact of maternal-level factors (nutritional, infectious, psychosocial), social factors (autonomy, social support, domestic violence), and household factors (socioeconomic status, food security) on early infant growth, and (4) evaluating whether maternal cortisol may be a mediator in the vertical transmission of stress.

In addition, Photovoice activities involved giving a camera to 23 women from study communities, who documented sources of stress vs. resilience for local women, and shared photo-elicited narratives through six group sessions. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
