Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Pharmacodynamics in Geriatric Patients: Effects of Age01:27

Pharmacodynamics in Geriatric Patients: Effects of Age

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...
Aging01:26

Aging

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...
Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

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...
The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
Regulation of Food Intake01:30

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Summary

A tailored nutrition intervention significantly increased fruit and vegetable (FV) intake in elderly Iranians. The program improved self-efficacy and readiness for dietary change, demonstrating the Transtheoretical Model

Area of Science:

  • Gerontology
  • Nutritional Science
  • Public Health

Background:

  • Adequate fruit and vegetable (FV) intake is crucial for elderly health.
  • Elderly populations often exhibit insufficient FV consumption.
  • Targeted interventions are needed to improve FV intake in older adults.

Purpose of the Study:

  • To assess the effectiveness of a tailored nutrition intervention.
  • To increase fruit and vegetable (FV) consumption among Iranians aged 60+.

Main Methods:

  • A quasi-experimental study conducted in Tehran, Iran (2008-2009).
  • Community-based sample of 400 elderly individuals (200 intervention, 200 control).
  • Data collected at baseline and 4-week follow-up using questionnaires on demographics, stages of change, self-efficacy, decisional balance, and FV intake.

Main Results:

  • The intervention group showed a significant increase in daily FV servings (3.08 vs. 1.79; P = 0.001).
  • Intervention participants reported higher FV intake, perceived benefits, and self-efficacy, with lower perceived barriers.
  • Significantly more individuals in the intervention group advanced through stages of change (P < 0.0001).

Conclusions:

  • A tailored nutrition intervention effectively enhanced FV intake in elderly Iranians.
  • The Transtheoretical Model is a valuable framework for promoting dietary behavior change in older adults.
  • Findings suggest applicability to similar populations and conditions globally.
