概括
电视直播消费者广告 (DTCA) 与美国男性的丸激素测试和开始增加有关. 这种关联甚至在没有最近的基线测试的情况下也被观察到,突出显示了广告对治疗决定的影响.
科学领域:
- 内分泌学
- 公共卫生
- 关于健康的信息
背景情况:
- 在2000年至2013年期间,美国的激素发射量急剧增加,尤其是在缺乏明确医疗指示的男性中.
- 同时,在此期间,的直接向消费者广告 (DTCA) 显著增加.
研究的目的:
- 检查电视直播广告与美国测试率之间的关系.
- 调查DTCA与开始治疗之间的关联.
- 在没有最近的基线测试的情况下,评估DTCA是否会影响激素的启动.
主要方法:
- 采用了生态研究设计,分析了美国75个指定市场区域 (DMA) 的数据.
- 月度激素DTCA评级与商业保险索赔 (2009-2013) 中的激素水平使用数据相关.
- 用Poisson的概括估计方程来估计DTCA暴露和测试/启动之间的关联.
主要成果:
- 每个月的家庭广告曝光与新的丸激素测试 (RR, 1.006),启动 (RR, 1.007) 和没有最近测试的启动 (RR, 1.008) 的统计学显著增加相关.
- 每月每10,000名男性的平均绝对增加包括0.14个新测试,0.05个新启动和0.02个没有最近测试的启动.
- 广告的强度在地理上有所不同,在美国东南部的曝光率更高,并且随着时间的推移,从非品牌广告转向品牌广告.
结论:
- 在美国男性中,直接向消费者投放的丸激素广告与丸激素测试和启动率的增加有关.
- 这些发现表明DTCA可能有助于激素的启动,即使在最近的基线测试缺席的情况下.
- 这一关联凸显了广告对患者和医生的治疗决定的重大影响.

Testosterone: Functions and Regulation
2.7K
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...

Signs of Puberty
1.8K
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Disorders of the Male Reproductive System
5.3K
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.

Regression Toward the Mean
7.2K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Hormonal Regulation
36.5K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.
