Substance Use & Misuse
|March 28, 2008
Summary
Younger age of first alcohol use in Navajo adults is linked to higher risks of alcohol dependence and polysubstance use. This trend has been observed over the past 50 years in southwestern United States populations.
Area of Science:
- Public Health
- Epidemiology
- Substance Abuse Research
Background:
- Substance use, including alcohol and other drugs, poses significant public health challenges within Indigenous communities.
- Understanding the historical trends and risk factors associated with substance use is crucial for developing targeted interventions.
Purpose of the Study:
- To investigate the age of first alcohol use among Navajo Indians.
- To determine the relationship between the age of first alcohol use and the risk of alcohol dependence and polysubstance use.
- To analyze trends in the age of first alcohol use over the past 50 years within this population.
Main Methods:
- Utilized the Diagnostic Interview Schedule for data collection between 1993 and 1995.
- Surveyed 1,086 Navajo individuals residing on or near their reservation in the southwestern United States.
- Employed bivariate and multivariate statistical analyses to assess risk factors and trends.
Main Results:
- A significant decline in the age of first alcohol use was observed over the preceding 50 years.
- Earlier initiation of alcohol use was identified as a significant risk factor for developing alcohol dependence.
- Age of first alcohol use was also found to be a significant predictor of polysubstance use.
Conclusions:
- The findings highlight a concerning trend of earlier alcohol initiation among Navajo individuals.
- Early alcohol use is a critical risk factor for subsequent substance use disorders in this population.
- Further research and culturally appropriate interventions are needed to address these public health issues.

01:24Drug Toxicity: Risk factors
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
01:16Drug toxicity: Idiosyncratic Reactions
Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...
01:15Drug Abuse and Addiction: Pharmacological Phenomena
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...
01:29Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu
Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...
01:27Principles of Pharmacogenetics: Types of Genetic Variants
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...
01:17Drug Dependence
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...
