概括
从1999年至2012年,美国成年人饮食补充剂的使用总体保持稳定. 然而,多种维生素/矿物质的使用量有所减少,而维生素D和鱼油等特定补充剂的使用量有所增加.
科学领域:
- 公共卫生
- 营养流行病学
- 健康趋势
背景情况:
- 美国的成年人广泛使用食补充剂.
- 了解补充剂消费的最新趋势对于公共卫生倡议至关重要.
- 关于美国成年人饮食补充剂使用的变化模式的数据有限.
研究的目的:
- 分析和报告美国成年人饮食补充剂消费的趋势.
- 为了确定随着时间的推移使用任何补充剂,多维生素/多矿物质和个人补充剂的流行率的变化.
- 检查这些趋势在不同的人口分组中如何变化.
主要方法:
- 采用了连续的横截面研究设计,利用了1999-2012年国家健康和营养检查调查 (NHANES) 的全国代表性数据.
- 这项研究包括非住院的美国成年人,收集了七个2年调查周期的数据.
- 参与者接受了关于他们在前30天使用补充剂的采访,分析对国家代表性进行了加权,并按人口因素分层.
主要成果:
- 在1999年至2012年期间,饮食补充剂的使用总体保持稳定,约有52%的成年人报告在2011-2012年使用.
- 综合维生素/ 综合矿物质 (MVMM) 的使用量显著下降,从37%降至31%.
- 与此同时,使用维生素D补充剂 (不包括MVMM) 的比例从5.1%上升至19%,使用鱼油补充剂的比例从1.3%上升至12%.

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, 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...

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
787
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.
