In order to inform clinical treatment decisions and maximize treatment outcomes, this observational study set out to examine the relationship between pathological severity and sleep quality in patients with CAG. The idea that "if the stomach is not in harmony, you will be restless" is supported by this evidence from traditional Chinese medicine. Assessing patients' knowledge and acceptance of acupuncture therapy, determining the current general trend in CAG treatment, and assessing the initial effectiveness of acupuncture therapy in treating CAG with sleep disturbances. It is envisaged that the aforementioned investigations will aid in further refining the clinical research strategy of acupuncture and moxibustion with CAG with sleep disorders, enhance the effectiveness of treatment, and offer a more cost-effective and practical choice for treating CAG with sleep disorders.

The primary research issue is: can the traditional Chinese medical notion of "restlessness due to disharmony of the stomach" be validated in order to ascertain whether there is a correlation between pathological severity and sleep quality in patients with chronic atrophic gastritis? The pathological conditions of CAG patients were gathered based on the most recent gastroscopy report within a year, and the patients' sleep quality scores from the previous month were gathered via a questionnaire.

This is a single-center, cross-sectional study

Inclusion Criteria:

1. Have been diagnosed with chronic atrophic gastritis;
2. Be between the ages of 18 and 75, with no restrictions on gender;
3. Read the informed consent form, sign it, and consent to participate in this study.

Exclusion Criteria:

1. autoimmune gastritis (chronic atrophic gastritis type A);
2. patients with gastroesophageal reflux disease (GERD) as determined by endoscopy or other examinations, or patients with high-grade intraepithelial neoplasia pathologically as determined by upper gastrointestinal endoscopy and gastric mucosal biopsy;
3. patients with confirmed or unexcluded malignant tumors, particularly esophageal and gastric cancer;patients with other upper gastrointestinal pathologies, such as Barrett's esophagus or peptic ulcer;
4. additional physical, mental, psychological, or pathological conditions that may impact sleep scores, such as the use of medications for insomnia, night shifts, jet lag, major events, severe neurosis, menopausal syndrome, uncontrolled hyperthyroidism, severe diabetic peripheral neuropathy, within a month after surgical trauma, etc.
5. People who use medicines that can make you sleepy at the same time and stop using them for less than a month;
6. People who can't finish the questionnaire because they're unconscious, can't talk regularly, or have other issues; people who don't have enough information.

This multicenter clinical investigation is coordinated by Zhejiang Chinese Medical University (ZCMU) with participant enrollment conducted at the Third Affiliated Hospital of ZCMU. To establish a conclusive diagnosis for each participant, the researchers conduct an upper gastrointestinal endoscopy screening and assess serum pepsinogen levels during recruitment, subsequently identifying and continuously enrolling all eligible patients at the aforementioned hospitals until the requisite sample size is attained.
