Impact of body mass index levels on lipid abnormalities in Chinese Asians, American Blacks and American Whites: the People's Republic of China (PRC) and Atherosclerosis Risk in Communities (ARIC) Studies. Atherosclerosis 2011; 218:517-23. [PMID: 21802083 PMCID: PMC3234685 DOI: 10.1016/j.atherosclerosis.2011.06.052] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2010] [Revised: 06/07/2011] [Accepted: 06/30/2011] [Indexed: 10/18/2022]
Abstract
BACKGROUND Several researchers have reported that Chinese adults may have a greater chronic disease burden than Whites, especially at lower body mass index (BMI) levels. OBJECTIVES To compare the incidence of lipid abnormalities in Chinese (n=5303), White (n=10,752) and Black (n=3408) middle-aged adults and the effect of BMI on these incidences. METHODS Data were from the People's Republic of China (PRC) and the Atherosclerosis Risk in Communities (ARIC) studies. In each ethnic group, we calculated the adjusted cumulative incidence for high total cholesterol (≥240mg/dL), LDL-cholesterol (≥160mg/dL), and triglycerides (≥200mg/dL) and low HDL-cholesterol (≤40 in men and ≤50mg/dL in women) adjusted for age, gender, education, field site, smoking and drinking status. Risk differences associated with BMI (referent=18.5-22.9kg/m(2)) were calculated using weighted linear regression and slopes compared using the Wald test. RESULTS Chinese had lower incidence of abnormal total cholesterol, LDL-cholesterol and triglycerides than Whites in most BMI groups and had lower incidence of abnormal HDL-cholesterol and triglycerides than Blacks. Across the range of 18.5 to <30, BMI was more strongly associated with the incidence of having high total cholesterol in Chinese and Whites than in Blacks. Similar trends were seen for LDL-cholesterol and triglycerides, but were not always statistically significant. In contrast, BMI was more highly associated with incidence of low HDL-cholesterol in Whites than in Chinese or Blacks. CONCLUSION Although differences in the incidence of lipid abnormalities and the impact of BMI were identified, results varied by lipid type indicating no consistent ethnic/national pattern.

Abstract
OBJECTIVE The relationship between body mass index (BMI) and stroke incidence and mortality remains controversial, particularly in Asian populations. METHODS We conducted a prospective cohort study in a nationally representative sample of 169,871 Chinese men and women age 40 years or older. Data on body weight was obtained at baseline examination in 1991 using a standard protocol. Follow-up evaluation was conducted in 1999 to 2000, with a response rate of 93.4%. RESULTS After excluding those participants with missing body weight or height values, 154,736 adults were included in the analysis. During a mean follow-up of 8.3 years, 7,489 strokes occurred (3,924 fatal). After adjustment for age, gender, physical inactivity, urbanization, geographic variation, cigarette smoking, diabetes, and education, compared with participants of normal weight (BMI 18.5-24.9), relative hazard (95% confidence interval) of incident stroke was 0.86 (0.80-0.93) for participants who were underweight (BMI < 18.5), 1.43 (1.36-1.52) for those who were overweight (BMI 25-29.9), and 1.72 (1.55-1.91) for those who were obese (BMI > or = 30). The corresponding relative hazards were 0.76 (0.66-0.86), 1.60 (1.48-1.72), and 1.89 (1.66-2.16) for ischemic stroke and 1.00 (0.89-1.13), 1.18 (1.06-1.31), and 1.54 (1.27-1.87) for hemorrhagic stroke. For stroke mortality, the corresponding relative hazards were 0.94 (0.86-1.03), 1.15 (1.05-1.25), and 1.47 (1.26-1.72). Linear trends were significant for all outcomes (p < 0.0001). INTERPRETATION These results suggest that elevated BMI increases the risk of both ischemic and hemorrhagic stroke incidence, and stroke mortality in Chinese adults.

Abstract
BACKGROUND Observational studies suggest that moderate alcohol consumption may lower risk of myocardial infarction (MI) and coronary heart disease (CHD); yet, evidence for this comes almost entirely from Western populations. METHODS We conducted a prospective cohort study in 64,597 Chinese men aged > or = 40 years who were free of clinical CHD at baseline examination. Data on frequency and type of alcohol consumed were collected at the baseline examination in 1991 using a standard protocol. Follow-up evaluation was conducted in 1999-2000, with a response rate of 94%. RESULTS Over 494,084 person-years of follow-up, we documented 725 (361 fatal) incident MI and 976 (588 fatal) incident CHD events. After stratification by province to account for multi-stage sampling design and adjustment for age, education, physical activity, cigarette smoking, body mass index, systolic blood pressure, urbanization (urban vs. rural), geographic variation (north vs. south) and history of diabetes, relative risk (95% confidence interval) of MI was 0.93 (0.70-1.24) for participants consuming 1 to 6 drinks/week, 0.66 (0.54-0.82) for those consuming 7 to 34 drinks/week, and 0.58 (0.41-0.81) for those consuming > or = 35 drinks/week (p for linear trend <0.0001) compared to non-drinkers. The corresponding relative risks for CHD events were 0.99 (0.77-1.27), 0.67 (0.56-0.81), and 0.58 (0.44-0.78), respectively (p for linear trend <0.0001). CONCLUSION Alcohol consumption may be related to lower risk of MI and CHD in middle-aged and older Chinese men. However, heavy alcohol consumption may lead to increased mortality from other causes; therefore, the implications of these findings should be interpreted cautiously.

Abstract
We examined the relationship between alcohol consumption and incidence of end-stage renal disease (ESRD) in a prospective cohort of 65 601 Chinese men aged 40 years and older. Information on the amount and type of alcohol consumed was collected at a baseline examination with follow-up evaluations conducted 8-9 years later. During the 500 876 person-years of follow-up, 176 participants initiated renal replacement therapy or died from renal failure. Compared to non-drinkers, the relative risk of ESRD was 0.67 among men consuming less than 21 drinks per week and 0.52 among men consuming this amount or more after adjustment for age, geographic region, urbanization, education, body mass index, physical activity, and cigarette smoking. The inverse association between alcohol consumption and ESRD existed even after adjustment for systolic blood pressure, and history of diabetes and cardiovascular disease. Our results suggest an inverse relationship between alcohol consumption and risk of ESRD in Chinese men. Heavy alcohol consumption, however, may lead to increased risk of morbidity and mortality from other causes; therefore, the implications from these findings should be interpreted cautiously.

Abstract
BACKGROUND Most studies investigating the benefits of statins have focused on North American and European populations. This study focuses on evaluating the lipid-lowering effects of rosuvastatin and atorvastatin in Asian patients. OBJECTIVES The DIrect Statin COmparison of LDL-C Values: an Evaluation of Rosuvastatin therapY (DISCOVERY)-Asia study is one of nine independently powered studies assessing the efficacy of starting doses of statins in achieving target lipid levels in different countries worldwide. DISCOVERY-Asia was a 12-week, randomised, open-label, parallel-group study conducted in China, Hong Kong, Korea, Malaysia, Taiwan, and Thailand. RESULTS A total of 1482 adults with primary hypercholesterolaemia and high cardiovascular risk (> 20%/10 years, type 2 diabetes, or a history of coronary heart disease) were randomised in a 2 : 1 ratio to receive rosuvastatin 10 mg once daily (o.d.) or atorvastatin 10 mg o.d. The percentage of patients achieving the 1998 European Joint Task Force low-density lipoprotein cholesterol (LDL-C) goal of < 3.0 mmol/L at 12 weeks was significantly higher in the rosuvastatin group (n = 950) compared with the atorvastatin group (n = 471) (79.5 vs. 69.4%, respectively; p < 0.0001). Similar results were observed for 1998 European goals for total cholesterol (TC), and the 2003 European goals for LDL-C and TC. LDL-C and TC levels were reduced significantly more with rosuvastatin compared with atorvastatin. Both drugs were well-tolerated and the incidence and type of adverse events were similar in each group. TRIALS REGISTRATION The trial registry summary is available at http://www.clinicaltrials.gov/; ClinicalTrials.gov Identifier: NCT00241488 CONCLUSIONS This 12-week study showed that the starting dose of rosuvastatin 10 mg o.d. was significantly more effective than the starting dose of natorvastatin 10 mg o.d. at enabling patients with primary hypercholesterolaemia to achieve European goals for LDL-C and TC in a largely Asian population in real-life clinical practice. The safety profile of rosuvastatin 10 mg is similar to that of atorvastatin 10 mg in the Asian population studied here, and is consistent with the known safety profile of rosuvastatin in the white population.

Abstract
OBJECTIVE Stroke is a leading cause of death and long-term disability in China. The objective of this study was to examine the relation between alcohol consumption and risk for stroke among Chinese men. METHODS We conducted a prospective cohort study among 64,338 Chinese men aged > or = 40 years who were free of stroke at baseline. Data on frequency and type of alcohol consumed were collected at the baseline examination in 1991 using a standard protocol. Follow-up evaluation was conducted in 1999 to 2000, which included determining vital status, interviewing participants or proxies, and obtaining hospital and medical records for incident and fatal strokes. RESULTS Over the course of 493,351 person-years of follow-up, we documented 3,434 incident strokes (1,848 stroke deaths). After adjustment for age, body mass index, physical activity, urbanization (urban vs rural), geographic variation (north vs south), cigarette smoking, history of diabetes, and education, compared with nondrinkers, relative risk (95% confidence interval) of incident stroke was 0.92 (0.80-1.06) for participants consuming 1 to 6 drinks/week, 1.02 (0.93-1.13) for those consuming 7 to 20 drinks/week, 1.22 (1.07-1.38) for those consuming 21 to 34 drinks/week, and 1.22 (1.08-1.37) for those consuming 35 or more drinks per week (p for linear trend < 0.0001). The corresponding relative risks for stroke mortality were 0.93 (0.76-1.14), 0.98 (0.85-1.13), 1.15 (0.95-1.38), and 1.30 (1.11-1.52), respectively (p for linear trend = 0.0004; p for quadratic trend = 0.03). INTERPRETATION These results suggest that heavy alcohol drinking may increase the risk for stroke in Chinese men and should be the target of strategies for prevention.

Abstract
The purpose of this study was to evaluate risk pattern and mortality in a general population epidemiologic study performed by a staff of hypertension specialists working as the "good father of a family," with lifestyle and therapeutic advice and instrumental measurements. Mortality among the study population (n=856) during the 4-y study was compared with that recorded in the general population during the 4-y period before the study; those who refused to participate in the study were also recorded (n=280). Among study subjects, blood pressure decreased by 3.6/3.5 mm Hg (P<.01/P<.0001), serum total cholesterol by 3.8% (P<.0001), and low-density lipoprotein cholesterol by 10.9% (P<.01); awareness of hypertension increased by 87% (P<.0001); 20% of hypercholesterolemic patients (P<.01) and 28% of diabetic patients (P<.001) were identified; and 40% of hypertensive patients (P<.0001) were treated. Overall 4-y mortality was 12.5% in study subjects, 36.6% in renitent subjects (P<.0001 vs enrolled), and 19.9% during the period preceding the study (P<.0001 vs enrolled); cardiovascular mortality rates were 5.8%, 18.6% (P<.0001), and 11.4% (P<.0001), respectively. In particular, the frequency of fatal stroke was 0.06%, 3.8% (P<.0001), and 2.5% (P<.0001), respectively, and that of fatal coronary events was 3.4%, 7.5% (P<.0001), and 4.6% (P<.0001), respectively. In conclusion, when an epidemiologic professional staff member approaches patients in a manner similar to that of the "good father of a family," a better risk pattern and lower mortality rates (particularly cerebrovascular and coronary) are seen in those who are receptive to the care provided; those who decide not to participate in health care opportunities do not benefit.
