教育越低, 血壓稍高 - 30年追蹤研究發現

123Go

最近發表一份統計研究指出, 教育程度越低, 平均血壓越高,
其中女性更顯著,  高出 3.26 mmHg ..... 男性為 2.26 mmHg.
Result :  3.26 mmHg, 95% CI: 1.46, 5.05 in females, 2.26 mmHg, 95% CI: 0.87, 3.66 in males).

Framingham Offspring Study
BMC Public Health 2011

Mixed linear models demonstrated that mean systolic blood pressure (SBP) over 30 years was higher for participants with .12 vs. .17 years education after adjusting for age (3.26 mmHg, 95% CI: 1.46, 5.05 in females, 2.26 mmHg, 95% CI: 0.87, 3.66 in males). Further adjustment for conventional covariates (antihypertensive medication, smoking, body mass index and alcohol) reduced differences in females and males (2.86, 95% CI: 1.13, 4.59, and 1.25, 95% CI: -0.16, 2.66 mmHg, respectively).

Additional analyses adjusted for baseline SBP, to evaluate if there may be educational contributions to post-baseline SBP. In analyses adjusted for age and baseline SBP, females with .12 years education had 2.69 (95% CI: 1.09, 4.30) mmHg higher SBP
over follow-up compared with .17 years education. Further adjustment for aforementioned covariates slightly reduced effect strength (2.53 mmHg, 95% CI: 0.93, 4.14). Associations were weaker in males, where those with .12 years education had 1.20 (95% CI: -0.07, 2.46) mmHg higher SBP over follow-up compared to males with .17 years of education, after adjustment for
age and baseline blood pressure; effects were substantially reduced after adjusting for aforementioned covariates (0.34 mmHg, 95% CI: -0.90, 1.68). Sex-by-education interaction was marginally significant (p=0.046).

CONCLUSION: Education was inversely associated with higher systolic blood pressure throughout a 30-year life course span, and associations may be stronger in females than males.

點解會咁呢？

孤寂如雲

我嘗試用常理解釋一下。

學歷越低，越難進入高收入行業。而低收入行業很多都是體力勞動。
經常做體力勞動，例如運動員和清潔工，因為需氧量較高，血壓會高於常人，以獲得更多的血液供應。

而女性血壓高，我覺得和體質也有很大關係。
