Brief Summary
This study examines the impact of Auxilio Brasil (AB), a cash transfer program to mothers of school-age children, on resource-deprived populations in Brazil and its protective effects on child neurodevelopment and mental health. The investigators will conduct a randomized clinical trial (RCT) among those already receiving AB in which 300 families will be randomized in a 1:1 ratio to receive either a high ($40/month) or low ($2/month) supplemental transfer for 2 years. Three hundred children (index child participants; 7-10 years old) will be enrolled across both study arms. Additionally, up to 150 siblings ("sibling participants;" 7-10 years old) will be enrolled. Eligible families who decide to participate will sign a study-specific informed consent (mother) and assent (child) form. The UNIFESP team will conduct the respective assessments at baseline, approximately 8- and 16- months, 24-months and approximately 6-months post-RCT. Aim 1: Determine the impact of high vs low cash transfers on children's exposure to adversities (ACEs) and neurodevelopment. Aim 2: Determine the impact of cash transfers on children's inflammatory markers and HPA activity/cortisol. Exploratory Aim: The investigators will explore (i) whether sex/gender of the children moderates the pathways in the above mediation model; and (ii) whether cash transfer-related effects persist 6 months post-RCT.

Access to health care
The assessment will be based on maternal report about each child's health care utilization history including primary care, urgent care, and hospital care. Primary care visits will be classified by purpose: vaccination, routine check-up, or sick visits. Similar procedures to the ones in place in our ongoing study will be used to obtain child medical records in the primary care unit.
