Total cholesterol ≥222 mg/dL was associated with an increased risk of developing hypertension compared to ≤167 mg/dL in working-age Japanese men (HR 1.28; 95% CI 1.06-1.56).

Does dyslipidemia increase the risk of developing hypertension in a working-age male population?
Elevated total cholesterol, LDL-C, non-HDL-C, and both low and high HDL-C levels are independently associated with an increased risk of developing hypertension in working-age men.
Effect estimate: HR 1.28 (95% CI 1.06-1.56)
BACKGROUND: Hypertension is one of the main comorbidities associated with dyslipidemia. This study aimed to examine the extent to which dyslipidemia increases the risk of developing hypertension in a Japanese working-age male population. METHODS AND RESULTS: We analyzed data from 14 215 nonhypertensive male workers (age 38±9 years) who underwent annual medical checkups. Subjects were followed up for a median of 4 years to determine new-onset hypertension, defined as blood pressure (BP) ≥140/90 mm Hg or use of antihypertensive medication. The associations between serum lipid levels and development of hypertension were examined. During the follow-up period, 1483 subjects developed hypertension. After adjusting for age, body mass index, impaired fasting glucose/diabetes, baseline BP category, alcohol intake, smoking, exercise, and parental history of hypertension, subjects with a total cholesterol (TC) level ≥222 mg/dL were at a significantly increased risk of developing hypertension (hazard ratio: 1.28; 95% CI: 1.06-1.56) compared to subjects with a TC level ≤167 mg/dL. Similar results were observed for subjects with high low-density lipoprotein cholesterol (LDLC) and non-high-density lipoprotein cholesterol (HDLC) levels. A U-shaped relationship was found between HDLC level and risk of hypertension; compared to the third quintile, the multiadjusted hazard ratio was 1.22 (95% CI: 1.03-1.43) in the lowest quintile and 1.34 (95% CI: 1.12-1.60) in the highest quintile. CONCLUSIONS: Elevated serum levels of TC, LDLC, and non-HDLC were associated with an increased risk of hypertension in working-age Japanese men. For HDLC, risk of hypertension was increased at both low and high levels.
Otsuka et al. (Wed,) conducted a cohort in Dyslipidemia (n=14,215). Total cholesterol ≥222 mg/dL vs. Total cholesterol ≤167 mg/dL was evaluated on New-onset hypertension (blood pressure ≥140/90 mm Hg or use of antihypertensive medication) (HR 1.28, 95% CI 1.06-1.56). Total cholesterol ≥222 mg/dL was associated with an increased risk of developing hypertension compared to ≤167 mg/dL in working-age Japanese men (HR 1.28; 95% CI 1.06-1.56).
