The objective of this study was to estimate the prevalence and distribution of hypertension and to determine the status of hypertension awareness, treatment, and control in the general adult population in China. The International Collaborative Study of Cardiovascular Disease in ASIA (InterASIA), conducted in 2000–2001, used a multistage cluster sampling(More)
OBJECTIVE An extensive association analysis of PON gene cluster (PONs) with coronary heart disease (CHD) was performed in Chinese Han population. METHODS AND RESULTS Thirty polymorphisms of PON1, PON2, and PON3 gene were identified by direct sequencing of genomic DNA derived from 48 randomly selected patients. Twelve polymorphisms were additionally(More)
Serum C-reactive protein (CRP) has been strongly implicated in the pathogenesis of coronary heart disease (CHD). We report here on the association between gene coding for CRP and CHD in the ethnic Han population of China. For this purpose two polymorphisms of −717A>G and +2147A>G of the CRP gene were identified by direct sequencing of genomic DNA derived(More)
BACKGROUND Few longitudinal studies have examined ethnic and sex differences, predictors and tracking stabilities of heart rate variability (HRV) at rest and in response to stress in youths and young adults. METHODS Two evaluations were performed approximately 1.5 years apart on 399 youths and young adults (189 European Americans [EAs] and 210 African(More)
BACKGROUND We explored the relationship of genetic variants of the serotonin transporter gene SLC6A4, a key regulator of the serotonergic neurotransmission, with both depressive symptoms and plasma interleukin-6 (IL-6) levels. METHODS AND RESULTS We genotyped 20 polymorphisms in 360 male twins (mean age, 54 years) from the Vietnam Era Twin Registry.(More)
BACKGROUND Despite evidence linking obesity to impaired immune function, little is known about the specific mechanisms. Because of emerging evidence that immune responses are epigenetically regulated, we hypothesized that DNA methylation changes are involved in obesity induced immune dysfunction and aimed to identify these changes. METHOD We conducted a(More)
We tested whether the heritability of heart rate variability (HRV) under stress is different from rest and its dependency on ethnicity or gender. HRV indexed by root mean square of successive differences (RMSSD) and high-frequency (HF) power was measured at rest and during 3 stressors in 427 European and 308 African American twins. No ethnic or gender(More)
BACKGROUND Many traditional risk factors for coronary artery disease (CAD) are associated with altered autonomic function. Inflammation may provide a link between risk factors, autonomic dysfunction, and CAD. We examined the association between heart rate variability (HRV), a measure of autonomic function, and inflammation, measured by C-reactive protein(More)
BACKGROUND Behavioral alterations, including depression, are frequent in individuals with the metabolic syndrome (MetS). Recent findings suggest that chronic activation of innate immunity might be involved. The objective of this study was to examine the relationship between MetS and depressive symptoms and to elucidate the involvement of inflammation in(More)
BACKGROUND Isolated systolic hypertension (ISH), more so than any other hypertension subtype, increases the risk for stroke and coronary heart disease. The prevalence of ISH versus other hypertension subtypes in the general Chinese adult population is not known. METHODS The prevalence of isolated systolic and isolated diastolic hypertension (IDH) was(More)
