概括
避免/限制性食物摄入障碍 (ARFID) 的DSM-5-TR标准可能无法准确地捕捉成年人的复杂症状. 与ARFID同时出现的体重和形状问题表明更严重的表现,表明需要进行诊断修订.
科学领域:
- 临床心理学 临床心理学
- 精神病学是一个精神病学.
- 饮食障碍 研究 研究 研究
背景情况:
- 精神疾病诊断和统计手册,第5版,文本修订 (DSM-5-TR) 禁止在厌食症 (AN),精神性 Bulimia (BN) 或身体形象障碍之外诊断避免/限制性食物摄入障碍 (ARFID).
- 这种诊断排除可能不反映临床实践和新兴研究中观察到的复杂症状.
- 有可能需要修订DSM-5-TR标准,以更好地涵盖ARFID陈述的范围.
研究的目的:
- 为了调查体重和/或形状激发的限制 (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.
- 提供经验证据,以告知对ARFID的DSM-5-TR诊断标准的潜在修订.
- 为了检查WSR如何影响ARFID症状的严重程度.
主要方法:
- 分析了5747名成年人中的一个大样本,这些成年人对ARFID的查结果呈阳性.
- 参与者被分为四组:有AN的ARFID (ARFID-AN),有BN的ARFID (ARFID-BN),有WSR的ARFID (ARFID-WSR) 和没有WSR的ARFID (ARFID-nWSR).
- 使用通用线性模型来比较ARFID症状严重程度测量 (NIAS,PARDI-AR-Q) 和饮食障碍检查问卷 (EDE-Q) 的分数.
主要成果:
- 与所有其他组相比,ARFID-nWSR组在ARFID维度上的得分明显较低.
- 参与ARFID-nWSR组的参与者满足DSM-5-TR标准A1至A3的几率较低,与减肥,营养不足和对营养补充剂的依赖有关.
- 与ARFID同时存在的WSR与更严重的ARFID症状有关.
结论:
- 结果表明一种混合的表型,其中ARFID特征与WSR相结合,与更严重的ARFID呈现有关.
- 当前的DSM-5-TR标准可能无法捕捉成年人真实世界ARFID症状的复杂性.
- 具有最严重症状的个体,可能包括具有同时发生的WSR的个体,可能会根据现有的标准被排除在准确诊断和必要治疗之外.

Binge Eating Disorders
403
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 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
649
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
2.2K
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
1.1K
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
4.5K
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,...
