About this study
Official title: Association Between Helicobacter Pylori Infection and Metabolic Syndrome: A Retrospective Cross-Sectional Study
This retrospective cross-sectional study evaluates the association between Helicobacter pylori infection and metabolic syndrome using health examination data from 5,218 adults at Nanjing First Hospital. Participants are divided into H. pylori-positive and negative groups based on urea breath test results. The primary outcome is metabolic syndrome prevalence (CDS 2020 criteria). Multivariable logistic regression will be used to assess the independent association, with subgroup analyses by age and sex.

What is being measured
The primary outcome is the main question the study is designed to answer.
Prevalence of Metabolic Syndrome
Metabolic syndrome is defined according to the Chinese Diabetes Society (CDS) 2020 criteria. Participants meeting three or more of the following five criteria are classified as having metabolic syndrome: (1) central obesity: waist circumference ≥90 cm in males or ≥85 cm in females; (2) hyperglycemia: fasting blood glucose ≥6.1 mmol/L or previously diagnosed diabetes on treatment; (3) hypertension: blood pressure ≥130/85 mmHg or previously diagnosed hypertension on treatment; (4) hypertriglyceridemia: fasting triglycerides ≥1.70 mmol/L; (5) low HDL-cholesterol: fasting HDL-cholesterol <1.04 mmol/L.
Measured: Baseline

Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Prevalence of Metabolic Syndrome (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
