まとめ
栄養サプリメントの使用は1999年から2012年にかけて,米国成人の間で全体的に安定した. しかし,ビタミンDや魚油などの特定のサプリメントの使用は減少した.
科学分野:
- 公衆衛生
- 栄養学的流行病学
- 健康 の 傾向
背景:
- ダイエットサプリメントは米国で大人が広く使用しています.
- 最近のサプリメント消費の傾向を理解することは 公衆衛生の取り組みにとって極めて重要です
- 米国成人のサプリメント使用パターンの進化に関するデータは限られている.
研究 の 目的:

主な方法:
- 1999年から2012年にかけての全国保健栄養調査 (NHANES) の代表的なデータを用いて,連続的な横断的な研究デザインが採用されました.
- この研究では,施設に入っていない米国の成人を対象に,7回の2年間の調査サイクルでデータを収集しました.
- 参加者は前30日間のサプリメント使用についてインタビューされ,分析は国の代表性により重み付けられ,人口統計的要因によって層分かれました.
主要な成果:
- 栄養補助食品の総摂取量は1999年から2012年の間に安定しており,2011年から2012年の間に約52%の成人が使用したと報告しています.
- 多ビタミン/多ミネラル (MVMM) の使用量は 37% から 31% に大幅に減少した.
- 同時に,ビタミンDサプリメントの使用は5.1%から19%に増加し,魚油サプリメントの使用は1.3%から12%に増加しました.
結論:
- 栄養補助食品の消費パターンは1999年から2012年まで全体的に安定した.
- マルチビタミンの使用が著しく減少した.
- 個々のサプリメントの傾向は多様で,異なる人口サブグループ間で異質性を示し,微妙な公衆衛生アプローチの必要性を強調しました.

Drug Regulation
3.2K
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...

Drug Dosing: Geriatric Patients
339
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...

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...

Pharmacodynamics in Geriatric Patients: Effects of Age
308
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

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...

Therapeutic Drug Monitoring: Affecting Factors
313
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.
