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:
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,...
Bioavailability Study Design: Healthy Subjects Versus Patients01:15

Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
Surveys02:16

Surveys

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.
Models of Health Promotion and Illness Prevention II01:18

Models of Health Promotion and Illness Prevention II

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results from...

Summary

This study examined the health of immigrants in Ireland between 1996 and 2008. Limited evidence supports a

Area of Science:

  • Sociology
  • Public Health
  • Demography

Background:

  • Ireland experienced significant economic and social changes from 1996-2008.
  • A major shift occurred from net emigration to substantial net immigration.
  • Little research exists on immigrant health status in Ireland, unlike in other major immigrant-receiving nations.

Purpose of the Study:

  • To investigate the health status of immigrants in Ireland.
  • To determine if a 'healthy immigrant' effect is present in the Irish context.
  • To explore factors influencing immigrant health in Ireland.

Main Methods:

  • Utilized microdata from a 2007 nationally representative population survey.
  • Analyzed health status of immigrants compared to native-born individuals.

  • Considered the duration of stay in Ireland.
  • Main Results:

    • Found only limited evidence supporting a 'healthy immigrant' effect in Ireland.
    • The Irish immigration experience differs from that of countries with established 'healthy immigrant' research.
    • Distinctive features of the Irish immigrant population may influence findings.

    Conclusions:

    • The 'healthy immigrant' effect is not strongly evident in Ireland.
    • Further research is needed to understand immigrant health in Ireland.
    • Specific characteristics of Irish immigration may account for the observed results.
