Determinants of Infant Mortality in the Interior of the State of Rondônia: Implications for the Regional Development of the Jamari Valley
Quality of Life. Social Determinants of Health. Public Policies. Health Indicator.
Infant mortality due to preventable causes remains an important indicator of social inequalities
and weaknesses in the organization of health services, especially in Amazonian territories
marked by structural limitations in access and socioeconomic vulnerabilities. In this context,
this study aims to investigate the determinants of infant mortality in the Vale do Jamari region,
in the state of Rondônia, Brazil, relating the impacts of this indicator to regional development.
To this end, the study analyzes the evolution of preventable infant and fetal mortality between
2010 and 2025, seeking to understand how socioeconomic factors, conditions of access to
health services, and changes in the health contexto, including the effects of the COVID-19
pandemic, have influenced the occurrence of these deaths. This is a quantitative ecological
study based on secondary data obtained from the Mortality Information System (SIM), the Live
Birth Information System (SINASC), the Brazilian Institute of Geography and Statistics
(IBGE), the Primary Health Care Information System (SISAB), and the Integrated Health
Surveillance Platform (IVIS), complemented by the analysis of municipal management
documents. The dependent variables correspond to preventable infant and fetal mortality rates,
while the independent variables include per capita income, maternal education, basic sanitation
conditions, Family Health Strategy (ESF) coverage, adequacy of prenatal care, and low birth
weight. The analysis will include time series, trend tests, and correlation with social
determinants of health. The study is expected to identify differentiated patterns among
municipalities and to demonstrate associations between preventable mortality and social
vulnerabilities. By dialoguing with Target 3.2 of the Sustainable Development Goals (SDGs),
the study aims to support public policies focused on strengthening Primary Health Care and
maternal-child health care, contributing to greater equity and improved quality of life in the
Vale do Jamari region.
