Insights

This study identified three distinct patterns of cardiovascular disease risk factors in Iranian adults aged 40-70. Demographic factors like female gender and Fars ethnicity were associated with higher clinical and lifestyle risks.

Area of Science:

  • Public Health
  • Epidemiology
  • Cardiology

Background:

  • Cardiovascular diseases (CVDs) are a major global health concern, with a significant impact in Iran.
  • Research on modifiable CVD risk factor patterns in Iran is limited.
  • Understanding these patterns is crucial for targeted prevention strategies.

Purpose of the Study:

  • To identify distinct patterns of modifiable CVD risk factors in Iranian adults aged 40 and above.
  • To explore the associations between demographic characteristics and these identified risk factor patterns.

Main Methods:

  • Utilized data from the Kherameh cohort study, including 9,422 participants aged 40-70 without pre-existing CVDs.
  • Employed Latent Class Analysis (LCA) to identify risk factor patterns.
  • Used multinomial logistic regression to analyze the relationship between demographic variables and latent classes.

Main Results:

  • Identified three distinct latent classes: low-risk (42%), clinical-risk (52%), and lifestyle-risk (6%).
  • Female gender, older age, and rural residence were associated with an increased risk of belonging to the clinical-risk class.
  • Fars ethnicity showed a significantly higher risk for both the clinical-risk and lifestyle-risk classes.

Conclusions:

  • Distinct patterns of modifiable CVD risk factors exist within the Iranian adult population.
  • Demographic factors play a significant role in the distribution of these risk patterns.
  • Findings can inform the development of tailored preventive strategies and health protocols for CVD risk reduction.

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.

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

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...

Hazard Ratio01:12

Hazard Ratio

The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial...

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.

Assessment of the Cardiovascular System I: Subjective Data

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...
