Prescription, Nonprescription and Orphan Drugs01:02

Prescription, Nonprescription and Orphan Drugs

Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...
Vitamins01:30

Vitamins

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists01:30

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function. They...
Factors Affecting Drug Response: Overview01:21

Factors Affecting Drug Response: Overview

When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...
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...
Drug Regulation01:25

Drug Regulation

Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

Summary

Most adults use dietary supplements for overall health, not specific nutrient deficiencies. Health care providers infrequently recommend supplements, despite users often having healthier lifestyles.

Area of Science:

  • Nutritional Science
  • Public Health
  • Health Behavior

Background:

  • Dietary supplement use is prevalent among US adults.
  • Motivations for supplement use have not been extensively studied using national data.
  • Understanding these motivations is crucial for public health initiatives.

Purpose of the Study:

  • To investigate the primary motivations behind dietary supplement consumption in US adults.
  • To identify the types of supplements used for common health goals.
  • To assess the influence of healthcare providers on supplement choices.

Main Methods:

  • Analysis of data from the 2007-2010 National Health and Nutrition Examination Survey.
  • Inclusion of a nationally representative sample of 11,956 US adults (≥20 years).
  • Cross-sectional, population-based survey design.

Main Results:

  • The leading reasons for supplement use were improving (45%) or maintaining (33%) overall health.
  • Specific motivations varied by demographics: women cited bone health (calcium), men cited heart health (18%).
  • Older adults focused on site-specific health (heart, bone, eye); only 23% of use was provider-recommended.

Conclusions:

  • Adults primarily use supplements for general health rather than to compensate for dietary nutrient gaps.
  • Dietary supplement users tend to exhibit healthier lifestyle choices compared to non-users.
  • Physician recommendations play a limited role in adult dietary supplement choices.
