    A cross-sectional study of 21,665 Japanese residents was performed to investigate the prevalence of central sensitization syndromes (CSS). CSS were assessed using the Central Sensitization Inventory (CSI-A). CSS were defined as a CSI-A score of 40 or higher. Age, sex, district, 10 CSS-related diseases (CSI-B), lifestyle, and mental factors were rated in a self-reported survey. The prevalence of CSS and its relationship with potential factors were examined by sex using descriptive and logistic regression models. The prevalence of CSS was 4.2% in all participants and was significantly higher in women (4.9%) than in men (2.7%). Adjusted odds ratios correlated with CSS for an age of 80–97 years versus 60–79 years (2.07 and 2.89), one or more CSI-B diseases (3.58 and 3.51), few sleeping hours (2.18 and 1.98), high perceived stress (5.00 and 4.91), low (2.94 and 2.71) and high (0.45 and 0.66) resilience versus moderate resilience, and exercise habits (0.68 and 0.55) in men and women (all P < 0.05). The relationship between CSS and age 20 and 59 years, ex-smokers, coffee intake, and alcohol intake differed by sex. The prevalence of CSS was estimated to be low in the healthy population. CSS correlated with CSS-related diseases and some positive and negative factors.

    I tried to find a copy of the Central Sensitization Inventory (CSI-A).
    All I could find was a general description that it's a list of symtoms with a Likert scale asking for how often patients experience each symptom. So a higher score means you report experiencing more symptoms more of the time.
    CSI-B asks patients to say which of a list of conditions they have been diagnosed with.

    CSS is just a presumed mechanism with no theoretical basis and has never been observed or demonstrated. The questions are typically about illness so all this does is "find" people who ongoing illness, absolutely zero relation to whatever CSS is supposed to be.

    Literally all they do is ask about common illness symptoms, this is weaker than homeopathic hot-dog water: https://www.pridedallas.com/wp-content/uploads/2016/04/csi_english.pdf.

    perhaps some one could create a meaningless buzzword in a parody paper and then do a trawl of papers using said buzzword a year or two later . just to show how many authors really do not have a clue about the field they work in .
