Insights

Preventable infant deaths are linked to prematurity for newborns and low maternal education for post-neonatal deaths. Identifying these factors is crucial for targeted interventions to reduce infant mortality.

Area of Science:

  • Public Health
  • Epidemiology
  • Demography

Background:

  • Infant mortality remains a significant public health concern globally.
  • Understanding factors contributing to preventable infant deaths is essential for developing effective interventions.

Purpose of the Study:

  • To identify specific factors associated with preventable infant deaths.
  • To differentiate between neonatal and post-neonatal preventable mortality factors.

Main Methods:

  • An epidemiological, population-based study utilizing 2020 data.
  • Employed data from the Mortality Information System (MIS).
  • Used a preventability classification from the Brazilian Health System List of Causes of Deaths Preventable by Interventions.

Main Results:

  • Preventable neonatal deaths were associated with prematurity, residence in North/Northeast regions, and in-home deaths.
  • Preventable post-neonatal deaths were linked to out-of-hospital deaths, low maternal education, and specific child race/color (brown or yellow).

Conclusions:

  • Prematurity is the primary risk factor for preventable neonatal deaths.
  • Low maternal education and out-of-hospital deaths are key factors for preventable post-neonatal deaths.

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Factors Affecting Illness01:18

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Lifestyle Factors and Health

Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.
Benefits of Physical Activity
Physical activity, whether through structured exercise or casual activities like walking, biking, or dancing, is a cornerstone of a...

Relative Risk01:12

Relative Risk

Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...
