Factors Affecting Illness

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,...

Bias in Epidemiological Studies

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:

Longitudinal Research

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Stereotypes, Prejudice, and Discrimination

Stereotypes, Prejudice, and Discrimination

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Dimensions of Health and Illness

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

Prevalence and Incidence

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Summary

This summary is machine-generated.

Racial and ethnic older adults face higher risks of developing complex multimorbidity and mortality. Targeted interventions are crucial to prevent disease progression and improve health outcomes in these populations.

Epidemiology

Background:

Understanding the progression and changes in multimorbidity is limited.
Multimorbidity significantly impacts health outcomes in aging populations.

Purpose of the Study:

To assess changes in multimorbidity patterns among diverse middle-aged and older adults over 16 years.
To identify distinct multimorbidity trajectories and their associations with demographic factors.

Main Methods:

A prospective cohort study utilizing latent class analysis and multinomial logistic models.
Analysis of Health and Retirement Study data from 1998 to 2014 (N=17,297).
Identified latent classes based on hypertension, heart disease, lung disease, diabetes, cancer, arthritis, stroke, and depressive symptoms.

Main Results:

Three distinct multimorbidity classes were identified in 1998 and 2014.
Participants in the cardiovascular-musculoskeletal class in 1998 were more likely to develop multisystem multimorbidity by 2014.
Individuals in the cardiovascular-musculoskeletal-mental class had higher odds of mortality or loss to follow-up.
Hispanic and Black Americans showed increased likelihood of multisystem multimorbidity and mortality compared to White Americans.

Conclusions:

Racial and ethnic minority older adults experience accelerated morbidity accumulation and higher mortality rates.
Targeted prevention and intervention strategies are essential for this demographic to mitigate complex multimorbidity.
Addressing health disparities is critical for improving long-term outcomes in aging populations.
