Summary
Women have higher gallbladder disease (GBD) prevalence in Brazil, but men face worse outcomes. This study analyzed GBD epidemiology by gender and ethnicity in the Brazilian public health system.
Area of Science:
- Epidemiology
- Public Health
- Surgical Pathology
Background:
- Gallbladder diseases (GBD) are common conditions requiring surgical intervention.
- Sex and ethnic characteristics may influence GBD prevalence and outcomes.
- Understanding these disparities is crucial for public health strategies.
Purpose of the Study:
- To evaluate gender and ethnicity-related differences in GBD epidemiology.
- To analyze GBD prevalence and outcomes within the Brazilian public health system.
Main Methods:
- Utilized DATASUS to retrieve ICD-10 code K80 (gallbladder disease) data from 2008-2019.
- Analyzed admissions, care modality, deaths, and in-hospital mortality rates by gender and ethnic groups.
Main Results:
- Over 2.8 million GBD admissions occurred between 2008-2019, with 77.3% in females.
- Male patients had a significantly higher in-hospital mortality rate (15.9/1,000) vs. females (6.3/1,000).
- Men exhibited a higher risk of death (RR=2.5) and longer hospital stays across all ethnic groups.
Conclusions:
- Women have the highest prevalence of GBD hospital admissions in Brazil.
- Men consistently face worse outcomes, including higher mortality, irrespective of ethnicity.
- Findings highlight significant gender-based disparities in GBD epidemiology and outcomes.

The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins...

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

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:

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
