RESUMEN
BACKGROUND: This study was operated to investigate the association between urinary albumin-to-creatinine ratio (ACR) and prehypertension among Chinese Han women. METHODS: Information on blood pressure measurement and other variables were obtained, and blood and urine samples collected in 1796 women aged ≥30 years. The association between urinary ACR and prehypertension were analyzed by using multivariate non-conditional logistic regression models. RESULTS: Average urinary ACR was higher in hypertensives than in prehypertensives (median: 15.54 vs 9.01 mg/g), and in prehypertensives than in normotensives (median: 9.01 vs 7.13 mg/g). Both systolic and diastolic blood pressures increased with urinary ACR. Compared with the lowest quartile of urinary ACR, multivariate adjusted odds ratios of prehypertension were 1.25 (95% confidence interval, 0.89-1.78), 1.95 (1.30-2.92) and 1.59 (1.02-2.48) for the second, third and fourth quartiles, respectively. After exclusion of subjects with diabetes or use of antihypertensive medication, the odds ratio of prehypertension still increased with urinary ACR levels. CONCLUSION: Increased urinary ACR was significantly and positively associated with prehypertension among Chinese Han women.

BACKGROUND: Corin has been suggested to be associated with hypertension by cell- and animal-based studies. However, the association still lacks population-based evidence which critically promotes translation from basic research to clinical and preventive practice. Here, we aimed to explore the association in a general population of China. METHODS: From January to May 2010, we conducted a cross-sectional study in 2,498 participants aged above 30 years, residing in Gusu district of Suzhou. Serum soluble corin and blood pressure were measured. RESULTS: Hypertensive participants had a higher level of serum corin than nonhypertensive participants (median (interquartile range): 1,836.83 (1,497.85-2,327.87) pg/ml vs. 1,579.14 (1,322.18-1,956.82) pg/ml, P < 0.001). Higher serum corin was positively associated with prevalent hypertension (odds ratio (OR) = 2.01, P < 0.001). In the multiple analysis, participants in the third (OR = 1.43, P = 0.007) and fourth (OR = 1.96, P < 0.001) quartiles had significantly increased odds of hypertension compared to those in the lowest quartile of serum corin. ORs of hypertension positively and significantly increased with serum corin levels (P for trend <0.001). Further subgroup analysis showed that ORs of hypertension associated with high corin (over the median level of serum corin: 1,689.20 pg/ml) were still significant in subgroups by age, body mass index, total cholesterol, low-density lipoprotein cholesterol, and fasting plasma glucose (all P < 0.05). CONCLUSIONS: Our study showed that hypertensive participants had an increased serum corin level compared to those without hypertension. This ï¬nding suggests that corin may play a role in the pathology of hypertension.

OBJECTIVE: This study was operated to investigate the association between urinary albumin-to-creatinine ratio (UACR) and physical situations as hypertension and prehypertension among women. METHODS: Blood pressure, height, weight and waist circumference were measured and factors such as cigarette smoking, alcohol intake, family history of hypertension, were investigated. Blood glucose and lipid, serum uric acid, urinary albumin and urinary creatinine were tested on 1796 women aged ≥ 30 years living in the Jinchang district of Suzhou. Associations between UACR and hypertension as well as prehypertension were analyzed, by using ordinal multinomial logistic regression models. RESULTS: The mean levels of UACR were 15.54 (7.67, 32.53), 9.01 (5.45, 18.06), 7.13 (4.60, 12.50) mg/g and the rates of higher UACR were 27.57%, 13.42%, 9.61% in hypertensive, pre-hypertensive and normotensive subjects, respectively, with significant differences noticed among the three groups (P < 0.05). The average systolic blood pressure/diastolic blood pressure appeared to be 125.3/80.9, 128.8/82.7, 130.8/84.0 and 135.1/85.9 mm Hg for participants with UACR in the first, second, third and fourth quartile, respectively. The risks of prehypertension or hypertension increased with increasing UACR levels. Dose-response relationship was seen between UACR and risks of prehypertension or hypertension. Multivariable adjusted odds ratios (95%CI) of prehypertension or hypertension in the upper quartiles of UACR were 1.32 (1.02, 1.70), 1.72 (1.32, 2.24), and 2.37 (1.80, 3.11), respectively, when compared with the lowest quartile. CONCLUSION: Elevated UACR was associated with both hypertension and prehypertension among women.

BACKGROUND: Whether hyperuricemia and microalbuminuria are separately associated with prehypertension among Chinese Han women is controversial. METHODS: Information was collected from physical examinations, personal interviews, and blood and urine samples. Associations of hyperuricemia and microalbuminuria with hypertension and prehypertension were analyzed by using multivariate nonconditional logistic regression models in 1,773 women aged ≥30 years. RESULTS: Both average systolic and diastolic blood pressure increased with uric acid and urinary albumin-to-creatinine ratio levels (all trend P values<0.001). When subjects with microalbuminuria or using antihypertensive medication were excluded, individuals with a uric acid level in the 2(nd), 3(rd), and 4(th) quartiles of uric acid were more likely to have prehypertension than those with a uric acid level in the lowest quartile [odds ratio (OR)=1.50, 95% confidence interval (CI) 1.02-2.19; OR=1.69, 95% CI 1.12-2.56; OR=2.67, 95% CI 1.57-4.53). After exclusion of subjects with diabetes or hyperuricemia or using antihypertensive medication, compared with normotensives, individuals with high blood pressure status of prehypertension were more likely to have microalbuminuria (OR=1.83, 95% CI 1.12-2.99). Additionally, microalbuminuria was positively associated with blood pressure levels (trend P value<0.001). CONCLUSIONS: Hyperuricemia and microalbuminuria are separately and independently associated with prehypertension among Chinese Han women.

OBJECTIVE: To investigate the association between serum nitric oxide (NO) and hypertension among women in Suzhou. METHODS: Blood pressure, height, weight and waist circumference (WC) were measured and factors including smoking, alcohol intake, family history of hypertension were investigated and blood glucose, blood lipid, serum NO were tested among 1453 women aged ≥ 30 years who lived in Jinchang district of Suzhou. Association between serum NO and hypertension was analyzed by univariate and multivariate methods. RESULTS: The mean levels of serum NO in hypertensive and normotensive persons were 28.17 (17.42 - 45.30) µmol/L and 27.56 (17.19 - 44.42) µmol/L, respectively, with no significant difference between the two groups (P > 0.05). RESULTS: from multivariable logistic regression analysis showed that low serum NO was not associated with hypertension, after adjustment for confounders (OR = 0.979, 95%CI: 0.747 - 1.283). The mean levels of systolic blood pressure/diastolic blood pressure were 130.1/83.3, 128.5/82.7, 129.8/83.2 and 129.1/83.3 mm Hg for whose serum NO level were in the first, second, third and fourth quartile, respectively. The risk of hypertension did not change along with the elevated serum NO levels. Compared to the first quartile of serum NO, the risks of hypertension in the second, third and fourth quartile did not change after adjustment for confounders and OR were 0.988 (0.709 - 1.377), 1.001 (0.720 - 1.390) and 1.077 (0.774 - 1.499), respectively. CONCLUSION: The serum NO level was not associated with hypertension in women in Suzhou.
