Substantial racial/ethnic variation in HTN prevalence, treatment, and control was found in our study population. Filipino and NHB women and men are at especially high risk for HTN and may have more difficulty in achieving adequate blood pressure control.

The relative ability of three obesity indices to predict hypertension (HTN) and diabetes (DM) and the validity of using Asian-specific thresholds of these indices were examined in Filipino-American women (FAW). Filipino-American women (n = 382), 40–65 years of age were screened for hypertension (HTN) and diabetes (DM) in four major US cities. Body mass index (BMI), waist circumference (WC) and waist circumference to height ratio (WHtR) were measured. ROC analyses determined that the three obesity measurements were similar in predicting HTN and DM (AUC: 0.6–0.7). The universal WC threshold of ≥ 35 in. missed 13% of the hypertensive patients and 12% of the diabetic patients. The Asian WC threshold of ≥ 31.5 in. increased detection of HTN and DM but with a high rate of false positives. The traditional BMI ≥ 25 kg/m2 threshold missed 35% of those with hypertension and 24% of those with diabetes. The Asian BMI threshold improved detection but resulted in a high rate of false positives. The suggested WHtR cut-off of ≥ 0.5 missed only 1% of those with HTN and 0% of those with DM. The three obesity measurements had similar but modest ability to predict HTN and DM in FAW. Using Asian-specific thresholds increased accuracy but with a high rate of false positives. Whether FAW, especially at older ages, should be encouraged to reach these lower thresholds needs further investigation because of the high false positive rates.

Healthcare providers should be concerned with improving the quality of life (QOL) of patients with heart failure (HF) because disease-specific QOL is linked to disease progression. The present study investigated the significance of elevated b-type natriuretic peptide (BNP), NYHA classification and depression to HF-related QOL to develop better management strategies. Outpatient subjects with left ventricular systolic dysfunction (n=108; mean age=64.9+/-12) completed the self-administered Minnesota Living with Heart Failure questionnaire and the Center for Epidemiologic Studies Depression Scale. Functional status was measured using the New York Heart Association Classification (NYHA) and BNP concentrations were measured in plasma samples. Multiregression analysis determined that plasma BNP levels did not contribute significantly to the total QOL score while depression (r=0.63, t ratio=7.43, P<.0001) and NHYA class (r=0.47, t ratio=3.31, P<.001) were significant contributors. NYHA III subjects exhibited worse depression scores (II 15+/-7 and III: 22+/-10, P<.001) and elevated plasma BNP (II: 2.0+/-0.5 and III: 2.4+/-0.6, P<.001). Low-cost psychological assessments are recommended to evaluate depression and suggest that those HF patients with NYHA III be closely monitored for depression and reduced QOL.
