In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Introduction to Epidemiology

1.8K
Epidemiology, known as the cornerstone of public health, involves studying the distribution and determinants of health-related events in defined populations and applying these insights to control health issues. This is essential for understanding how diseases spread, identifying populations at greater risk, and implementing measures to control or prevent outbreaks. Epidemiology addresses not only infectious diseases but also non-communicable conditions like cancer and cardiovascular disease,...

Causality in Epidemiology

1.6K
Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...

Study Designs in Epidemiology

967
Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...

Confounding in Epidemiological Studies

802
Confounding in statistical epidemiology represents a pivotal challenge, referring to the distortion in the perceived relationship between an exposure and an outcome due to the presence of a third variable, known as a confounder. This variable is associated with both the exposure and the outcome but is not a direct link in their causal chain. Its presence can lead to erroneous interpretations of the exposure's effect, either exaggerating or underestimating the true association. This...

Área de la Ciencia:

  • Salud ambiental
  • Oncología
  • Epidemiología

Sus antecedentes:

  • El cáncer de vejiga es una preocupación de salud mundial importante.
  • Cada vez se implican más factores ambientales, especialmente contaminantes del agua.
  • Se está investigando el doble papel del agua como portador de contaminantes y como líquido protector.

Objetivo del estudio:

  • Revisar la evidencia epidemiológica sobre exposiciones relacionadas con el agua y el riesgo de cáncer de vejiga.
  • Evaluar el papel de contaminantes específicos (arsénico, SPD, nitratos, PFAS) y la ingesta de líquidos.
  • Sintetizar hallazgos sobre plausibilidad biológica y relevancia para la salud pública.

Principales métodos:

  • Síntesis integral de estudios epidemiológicos.
  • Enfoque en las principales exposiciones relacionadas con el agua y la ingesta total de líquidos.
  • Evaluación basada en la fuerza de la asociación, la plausibilidad biológica y la relevancia para la salud pública.

Principales resultados:

  • El arsénico y los subproductos de desinfección (SPD) muestran vínculos consistentes con un mayor riesgo de cáncer de vejiga.
  • Las asociaciones con nitratos y sustancias per- y polifluoroalquiladas (PFAS) son menos consistentes.
  • Un mayor consumo de agua demuestra un efecto protector, potencialmente por dilución de carcinógenos y aumento de la micción.

Conclusiones:

  • La calidad del agua potable es un determinante modificable del cáncer de vejiga.
  • Las acciones regulatorias y las estrategias conductuales (por ejemplo, la hidratación) pueden ayudar en la prevención.
  • Se necesita más investigación sobre contaminantes emergentes y políticas globales de seguridad del agua.
