Social Transfers for Exclusive Breastfeeding in Brazil: Protocol for a Randomized Controlled Trial

Social Transfers for Exclusive Breastfeeding in Brazil: Protocol for a Randomized Controlled Trial

Brazil has one of the highest levels of economic and health inequalities globally [28]. Most of Brazil’s wealth is held by 1% of the population, demonstrating the extreme disparities faced in the country [29,30]. To reduce these prominent wealth and health gaps, Brazil implemented a national conditional cash transfer program called Bolsa Família in 2003, which provides financial incentives to families from low-income communities to help support and improve child health and education [31,32].

Intention to Use Pre-Exposure Prophylaxis Among Age Groups of Brazilian Men Who Have Sex With Men: National Cross-Sectional Study

Intention to Use Pre-Exposure Prophylaxis Among Age Groups of Brazilian Men Who Have Sex With Men: National Cross-Sectional Study

We hypothesized that there are differences in the factors associated with Pr EP intention among MSM of different age groups residing in Brazil. This is a cross-sectional online survey study that includes MSM throughout Brazil, aged 18 years and older, from January 2020 to May 2021. A sample size calculation was performed using G*Power software (version 3.1.9.7; Heinrich Heine University Düsseldorf) to determine the sample size needed for the study.

Balancing Human Mobility and Health Care Coverage in Sentinel Surveillance of Brazilian Indigenous Areas: Mathematical Optimization Approach

Balancing Human Mobility and Health Care Coverage in Sentinel Surveillance of Brazilian Indigenous Areas: Mathematical Optimization Approach

Motivated by this, we integrated human mobility data with Indigenous population coverage to refine sentinel site selection in Brazil. The boundaries between wild landscapes and human settlements have been increasingly blurred by climate change, agricultural and urban expansion, deforestation, and landscape fragmentation. These compounding factors heighten Indigenous communities’ vulnerability to infectious disease spillover, which can rapidly spread to urban areas [17].
