Harada T, Yamauchi T, Miyawaki D, et al. - Researchers performed a cross‐sectional study to clarify how features of anorexia nervosa restricting type (AN‐R) changed over 30 years. They studied 996 female treatment‐seeking patients with AN‐R in Japan from 1988 to 2018. Demographics, BMI, and Eating Disorder Inventory scores were contrasted among three groups according to time of initial consultation: Group 1 (1988–1998), Group 2 (1998–2008), Group 3 (2008–2018). Data reported that the mean BMI at the initial consultation declined significantly by 0.6 kg/m² (from 14.0 kg/m² in Group 1 to 13.4 kg/m² in Group 3). There were significantly higher scored for drive for thinness, interpersonal distrust, and interoceptive awareness in Groups 2 and 3 vs Group 1. Over time, the range of age of onset is wider and the number of late‐onset AN‐R with prolonged delay in treatment has increased. This research demonstrates that, in Japan, the physical and psychopathological severity of AN-R has risen over the past 30 years. Interdisciplinary research is required to clarify the link between AN‐R and time trend.
