Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

94.8K
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...

Pharmacodynamics in Geriatric Patients: Effects of Age

175
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Drug Dosing: Geriatric Patients

209
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

215
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

208
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

217
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Summary

Ageism is prevalent among older adults in Mexican prisons, affecting over 20%. Factors like older age, illness, and violence increase discrimination risk, highlighting the need for age-inclusive prison policies.

Area of Science:

  • Gerontology
  • Criminology
  • Public Health

Background:

  • Ageism is a significant issue in correctional facilities, particularly for vulnerable incarcerated populations.
  • Understanding age-based discrimination among older adults in prisons is crucial for developing targeted interventions.

Purpose of the Study:

  • To examine the prevalence and determinants of age-based discrimination among incarcerated older adults in Mexico.
  • To identify factors associated with experiencing ageism within the prison system.

Main Methods:

  • Analysis of the 2021 National Survey of Incarcerated People, focusing on adults aged 50 and older (n=8,116).
  • Descriptive statistics to determine prevalence and reasons for discrimination.
  • Multinomial logistic regression to identify associated factors.

Main Results:

  • 21.4% of incarcerated older adults reported discrimination, with age cited as the primary reason by 11.6%.
  • Older women faced nearly double the likelihood of reporting ageism compared to men.
  • Discrimination was strongly associated with older age, hypertension, other illnesses, disability, perceived insecurity, and prior violence exposure.

Conclusions:

  • Age-based discrimination is a substantial and intersectional vulnerability for older adults in correctional settings.
  • Findings emphasize the necessity of age-responsive prison policies to ensure safety, equity, and dignified aging for this population.
