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, disability,...
Principles of Disease Surveillance01:26

Principles of Disease Surveillance

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...
Causality in Epidemiology01:21

Causality in Epidemiology

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...

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...
Bias in Epidemiological Studies01:29

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 Health01:20

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...

Summary

Urbanization in Sri Lanka is linked to increased noncommunicable diseases (NCDs) like diabetes and obesity. This study quantifies urbanicity, revealing its association with physical inactivity and higher NCD risk factors in adults.

Area of Science:

  • Public Health
  • Epidemiology
  • Urban Studies

Background:

  • Noncommunicable diseases (NCDs) pose a growing global health challenge.
  • The relationship between urbanization and NCDs is complex and requires further investigation, particularly in diverse settings like Sri Lanka.

Purpose of the Study:

  • To investigate the association between urbanization and NCDs in Sri Lanka.
  • To develop and apply a quantitative measure of urbanicity to assess its impact on chronic disease risk factors.

Main Methods:

  • Utilized data from the Sri Lankan Diabetes and Cardiovascular Study (n=4,485).
  • Constructed a 7-item "urbanicity" scale based on population size, density, access to services, economic factors, and housing quality.
  • Employed linear and logistic regression to analyze the relationship between urbanicity and NCD risk factors.

Main Results:

  • Higher urbanicity was significantly associated with increased physical inactivity in both men (OR=3.22) and women (OR=2.29).
  • Urbanicity correlated positively with high body mass index (men: OR=2.45; women: OR=2.92) and diabetes mellitus (men: OR=2.44; women: OR=2.10).

Conclusions:

  • A clear relationship exists between urbanicity and common modifiable risk factors for chronic diseases in Sri Lankan adults.
  • Urbanization is a significant factor influencing the prevalence of NCDs and their risk factors in Sri Lanka.
