Abstract
「高血圧の人」という一語が指す人の割合が、線の高さ(140/90 か 130/80 か)と、血圧を下げる薬を飲んでいる人の数え方でどれだけ動くかを、2023 年(令和5年)の国民健康・栄養調査の表(第22表の1・2、第23表の1・3、第56表)の人数で確かめた。表どうしの人数は一致する(服薬しない人 1577 人+服薬者 774 人=2351 人、測った値で 140/90 以上の 651 人=収縮期だけ 439 人+拡張期 90 以上 212 人)。 20 歳以上(男女計)で、「高血圧の人」の割合は、測った値 140/90 以上なら 27.6 %、140/90 か服薬(調査の定義)なら 47.6 %、測った値 130/80 以上なら 54.6 %、130/80 か服薬なら 64.2 % で、2.32 倍動く。線を 130/80 に下げて増える分と、服薬中の人を数えて増える分は年齢で入れ替わり、20〜49 歳では 15.4 ポイント対 2.6、70 歳以上では 12.7 対 33.3 である。服薬中の人の 60.6〜61.1 % は、測った値が 140/90 未満である。140/90 を越えたのがどちらの値かも年齢で違い、20〜49 歳では拡張期だけが 40.0 %、70 歳以上では収縮期だけが 83.8 % である。 本稿は公開の集計データの数の形を述べる構造的解釈であり、医学的な助言・診断・治療の推奨ではない。著者は医師ではない。個人の健康に関する判断は医師・医療機関に相談すること。査読を経ていないプレプリントである。新しい数学定理も新しい法則も主張しない。どの線引きが正しいかは論じない。一人の血圧が高いかどうかを判断するものではない。割合は調査の対象者のもので、国の人口の年齢構成にはそろえていない。都道府県や地域は比べない。出典:国民健康・栄養調査(e-Stat)を加工して作成。 作成にあたって:本稿の着想と内容は、著者自身の考察に基づくものです。文章の構成整理や英訳、数式の確認には AI(大規模言語モデル)の助力を得ました。最終的な内容の解釈や誤りがあれば、それらはすべて著者の責に帰します。お気づきの点があれば、ご教示いただければ幸いです。 ----- This paper checks how much the share of people meant by the one phrase "people with hypertension" moves with the height of the line (140/90 or 130/80) and with how people taking blood-pressure-lowering medication are counted, using the counts in the tables of the 2023 National Health and Nutrition Survey (Tables 22-1 and 22-2, 23-1 and 23-3, and 56). The counts agree across tables (1577 people not on medication + 774 on medication = 2351; the 651 measured at 140/90 or above = 439 systolic only + 212 with diastolic 90 or above). For adults aged 20 and over (both sexes), the share of "people with hypertension" is 27.6% if measured 140/90 or above, 47.6% if 140/90 or on medication (the survey's definition), 54.6% if measured 130/80 or above, and 64.2% if 130/80 or on medication — a 2.32-fold range. What lowering the line to 130/80 adds and what counting people on medication adds swap with age: 15.4 points against 2.6 at 20–49, and 12.7 against 33.3 at 70+. 60.6–61.1% of people on medication measure below 140/90. Which value crosses 140/90 also differs by age: at 20–49, 40.0% crossed on the diastolic value alone; at 70+, 83.8% on the systolic alone. This paper is a structural interpretation of the shape of numbers in public aggregate data; it is not medical advice, not a diagnosis, and not a treatment recommendation. The author is not a physician. Decisions about individual health should be discussed with a physician or a medical institution. This is a preprint that has not been peer reviewed. No new mathematical theorem and no new law are claimed. It does not argue which definition is right. It does not judge whether one person's blood pressure is high. The shares are those of the survey participants and are not aligned to the national age composition. Prefectures and regions are not compared.

Assistance from an AI (a large language model) was used for structuring, English translation, and checking the algebra. Any remaining errors or misinterpretations are solely the author's. Feedback and corrections are sincerely appreciated.
