概括
规避性/限制性食物摄入障碍 (ARFID) 可能与体重驱动的限制同时发生,挑战当前的诊断标准. 这项研究表明,DSM-5-TR可能无法完全捕捉成年人ARFID症状,影响诊断和护理.
科学领域:
- 精神病学是一个精神病学.
- 临床心理学 临床心理学
- 饮食障碍 研究 研究 研究
背景情况:
- 目前的DSM-5-TR预防性/限制性食物摄入障碍 (ARFID) 的诊断标准排除了与涉及身体形象障碍的饮食障碍的联合诊断,例如神经性厌食症 (AN) 和神经性 булимия (BN).
- 这种排除可能不准确地反映了临床实践和新兴研究中观察到的复杂症状.
- 需要调查ARFID成年人体重和/或形状驱动的限制 (WSR) 的同时发生情况,以告知诊断标准的潜在修订.
研究的目的:
- 为了调查体重和/或形状驱动的限制 (WSR) 在成年人中同时发生的情况,这些成年人对ARFID的查结果呈阳性.
- 提供证据,以告知对ARFID的DSM-5-TR诊断标准的潜在修订.
- 根据WSR的存在和同时出现的饮食障碍,检查ARFID症状严重程度的差异.
主要方法:
- 分析了5,747名成年人中的一个大样本,这些成年人对ARFID呈阳性查.
- 参与者被分为四组:有AN的ARFID,有BN的ARFID,有WSR的ARFID (不符合AN/BN标准) 和没有WSR的ARFID.
- 用了通用线性模型来比较ARFID和饮食障碍症状测量 (NIAS,PARDI-AR-Q,EDE-Q) 的组.
主要成果:
- 只有ARFID症状的组 (ARFID-nWSR) 在大多数ARFID维度上报告得分较低,而与同时出现AN,BN或WSR的组相比.
- 在ARFID-nWSR组中,满足与减肥,营养不足和心理社会干扰有关的核心DSM-5-TRARFID标准的几率较低.
- 混合表型,结合ARFID和WSR特征,与更严重的ARFID症状有关.
结论:
- 这些发现表明,目前的DSM-5-TR标准可能无法充分捕捉成年人ARFID症状的全谱,特别是当与WSR同时发生时.
- 排除患有WSR的个体可能会导致严重ARFID症状的人的诊断不足和治疗不足.
- 修订诊断标准以适应ARFID和WSR的同时发生是有必要的,以提高诊断准确性和患者护理.

Binge Eating Disorders
168
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Anorexia Nervosa
191
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Bulimia Nervosa
194
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Regulation of Food Intake
450
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Obesity
615
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Taste Buds and Receptors
2.8K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
