This study examines anthropometrically assessed nutritional status of the Bayash, the Roma population from the eastern Croatian region of Baranya, and compares it to the non-Roma general population of eastern Croatia. The analysis of nutritional status and diets is a segment of multidisciplinary anthropological and epidemiological survey of the Roma minority population in Croatia began in 2005. The Bayash are an ethnic group that arrived to Croatia from Romania most likely in the 19th century and speaks a distinct archaic dialect of the Romanian language. The Roma population of Baranya approximates 1,000 according to the 2001 census. The Bayash sample comprised 227 adults aged 18-65yrs. The women fall below the Croatian 10th percentile for stature and men track about the 10th percentile. Both sexes approximate the 25th percentile for body weight. Despite their diminutive size, the Bayash appear to have adequate nutritional status until the age of 35yrs after which their average BMI exceeds the value of 25 kg/m(2) and falls in the overweight category. However, 8% of Bayash are underweight (BMI<18.5) in contrast to 1% of the majority population in the region. Underweight rates are especially high in women (11%) compared to men (4%). The prevalence of overweight (BMI 25.0 to 29.9) of 30% is considerably lower than in the majority population (42%) while the prevalence of obesity (BMI>or=30.0) of 23% is approximately equal. Overall unsatisfactory nutritional status of the Bayash merits attention. It appears to be the product of unhealthy dietary habits and their socio-economic deprivation that resulted from their poor education and extremely high unemployment. 相似文献

The Roma (Gypsy) are the largest European minority population characterized by poverty, social exclusion as well as by numerous life-style and cultural specificities, which all could have an adverse impact on their cardiovascular health. This study assesses the prevalence of cardiovascular diseases (CVD) risk factors in community-based sample of 430 adult Roma, living in rural area of Croatia, by providing the actual and age-adjusted estimates using the European standard population. The most prominent classical CVD risk phenotypes (blood pressure, obesity, smoking, glucose and lipid profile) were selected, and the standard risk cut-offs were applied. The study has shown that compared to general population of Croatia, the Roma population bears a high CVD risk factors load related to smoking and high glucose level. The CVD risk factors prevalence in Roma also showed important sex and age patterns, the most imposing of which are the findings of higher prevalence of CVD risks in women (especially obesity and triglyceride levels) and the trend of higher body mass index (BMI) level in younger age group (18–34 years) which both stand in contrast to the trends characterizing the general population of Croatia. These findings are complemented by the trend of decreased risk in the oldest age group (65+ years) for all investigated CVD risk factors (with exception of triglycerides level) compared to the 50–64 age group. We conclude that the age and sex CVD risks pattern point to the health transition of this rural Roma population. As we expect the proportion of CVD in the Roma minority of Croatia to increase in the future along with further modernization of their lifestyle, the CVD prevention measures in this population are urgent and should be primarily targeted at women and at the younger segment of this population. 相似文献

A multidisciplinary anthropological and epidemiological pilot field study of the Bayash population living in 6 villages of the eastern Croatian region of Baranya has been performed in 2005/06. The Bayash (or Boyash) belong to the Roma minority population speaking a distinct archaic dialect of the Romanian language. Since the bone mineral density values in the Roma have not been explored so far and the prevalence of osteoporosis is unknown for this ethnic minority group a screening by means of the Sahara Hologic clinical bone sonometer has been performed on 232 voluntary participants (73 males and 159 females). The prevalence of osteoporosis (T-score <-2.5) in the Bayash aged 50 and older is found to be 9.1% in males and 34.4% in females, which is substantially higher than in the general population of Croatia. The prevalence of T-values ranging from -1 to -2.5 indicating osteopenia is found to be 63.6% in males and 45.3% in females, while T-values within the normal range are found only in 27.3% males and 20.3% females. In addition to the low bone mass in older subjects, the mean estimated bone mineral density in all age groups of Bayash men and women was lower in comparison to the manufacturer's reference ranges for European population of the same age. Since body size effects could not be declined, the reference values that would be appropriate for the Roma population should be further explored. The high estimated prevalence of developed osteoporosis calls for attention and the survey should also be extended to exploring the association of low bone mineral density with particular life style and reproductive factors present in this semi-sedentary Roma population. 相似文献

Cardiovascular disease (CVD) is a major cause of death around the world, with highest prevalence reported in minority Roma/Gypsy populations living in developed countries. Whether these differences are caused by unhealthy lifestyles or genetic factors remain unknown. The aim of our study was to examine the genotype frequencies of the rs10757274 polymorphism in the 9p.21 locus within ANRIL (antisense non-coding RNA in the INK4 locus), a long non-coding RNA located in the vicinity of the CDKN2A/2B inhibitors loci. ANRIL is understood to be the strongest genetic determinant of CVD in Caucasians. Using PCR-RFLP, we analysed the ANRIL rs10757274 polymorphism in 298 non-Roma (50% male) and 302 Roma/Gypsy (50% male) adult (39.5 ± 15.1 years and 39.2 ± 12.8 years, respectively) subjects. We found that frequencies of the ANRIL GG, GA and AA genotypes were 20.1%, 52.4% and 27.5% in the majority population and 32.9%, 47.9% and 19.2% in Roma/Gypsy subjects, respectively. The distribution of genotypes was deemed significantly different at P < 0.001. Within the Roma/Gypsy population, we detected increased prevalence of the CVD-associated GG genotype. Increased prevalence of CVD among Roma/Gypsies subjects may be significantly linked to genetic background. 相似文献

The objective of this study was to analyse the association between socioeconomic indicators and cardiovascular disease risk factors in adult residents of Rio de Janeiro city, Brazil. Data were obtained by direct interview and physical examination in a population-based cross-sectional study in the city of Rio de Janeiro, 1995-96. Subjects were selected by two-stage random sampling and information was collected on socioeconomic, anthropometric and demographic characteristics, as well as on existing risk factors for cardiovascular disease. An index to express the risk of cardiovascular disease (CVD) was built, based on the presence of two or more of the following risk factors: overweight (measured by the body mass index, BMI), fat location (measured by the waist-hip ratio index, WHR), smoking, hypertension, sedentary lifestyle and alcohol consumption. The association between this risk index and the socioeconomic variables level of schooling, per capita income and residence location (slum vs non-slum) was evaluated through logistic regression models that controlled for the age of the subjects. Two separate models were built, according to the gender of the subjects. Complete data were collected for 1413 males and 1866 females over the age of 20 years (82% of the intended sample). In the studied population, a considerable prevalence of risk for CVD was found: 42.2% among males and 65.4% among females. For males, the socioeconomic and demographic indicators retained in the logistic model were age (OR 1.01, 95% CI 1.00-1.01), level of schooling (1.77, 95% CI 1.39-2.26) and per capita income (OR 0.77, 95% CI 0.61-0.97). For females, the indicators retained were age (OR 1.02, 95% CI 1.01-1.02) and level of schooling (OR 2.26, 95% CI 1.84-2.77). The findings indicate that cardiovascular disease risk is already an alarming problem in the urban populations of developing countries, and that educational level is the most important socioeconomic factor associated with its presence. 相似文献

The metabolic syndrome, an assemblage of risk factors, viz., obesity, dyslipidemia, carbohydrate intolerance, and hypertension, associated with development of cardiovascular diseases and Type 2 diabetes, has become a major public health problem in the developed countries. However, data on its prevalence in worldwide populations, particularly in non-industrialized societies is sparse. We report the prevalence of metabolic syndrome in an island population of the eastern Adriatic coast of Croatia, a distinctly homogenous population living in relative isolation with a traditional way of life style pattern. The participants consist of 381 unrelated individuals (136 males, 245 females) from the island of Hvar, age 19 and above. Hvar is among the most populated Croatian islands with a total population of 11,459 individuals according to the 1991 census. Metabolic syndrome was assessed following the National Cholesterol Education Program (NCEP) criteria, with the exception of using body mass index and waist hip ratio as the predictors of obesity. Overall age-adjusted prevalence of metabolic syndrome is 26% (32% in males and 24% in females) with body mass index, and 42% (57% in males and 36% in females) with waist hip ratio as the measures of obesity. Pairwise correlations of the age and sex-adjusted individual components show that with the exception of fasting plasma glucose, the other components of metabolic syndrome are significantly associated with each other, suggesting their co-morbidity. In spite of adherence to a relatively traditional life-style pattern together with a "Mediterranean diet" and rural habitat, the prevalence of metabolic syndrome is substantially high in the population of Hvar. It is likely that factors other than nutritional practices, that might include genetic susceptibility, could potentially be important in predisposition to metabolic syndrome. 相似文献

Background
Black Caribbean women have a higher burden of cardiovascular disease (CVD) risk factors than their male counterparts. Whether this results in a difference in incident cardiovascular events is unknown. The aim of this study was to estimate the 10 year World Health Organization/International Society for Hypertension (WHO/ISH) CVD risk score for Jamaica and explore the effect of sex as well as obesity, physical activity and socioeconomic status on these estimates.Methods and Findings
Data from 40–74 year old participants in the 2007/08 Jamaica Health and Lifestyle Survey were used. Trained interviewers administered questionnaires and measured anthropometrics, blood pressure, fasting glucose and cholesterol. Education and occupation were used to assess socioeconomic status. The Americas B tables were used to estimate the WHO/ISH 10 year CVD risk scores for the population. Weighted prevalence estimates were calculated. Data from 1,432 (450 men, 982 women) participants were analysed, after excluding those with self-reported heart attack and stroke. The women had a higher prevalence of diabetes (19%W;12%M), hypertension (49%W;47%M), hypercholesterolemia (25%W;11%M), obesity (46%W;15%M) and physical inactivity (59%W;29%M). More men smoked (6%W;31%M). There was good agreement between the 10-year cardiovascular risk estimates whether or not cholesterol measurements were utilized for calculation (kappa –0.61). While 90% had a 10 year WHO/ISH CVD risk of less than 10%, approximately 2% of the population or 14,000 persons had a 10 year WHO/ISH CVD risk of ≥30%. As expected CVD risk increased with age but there was no sex difference in CVD risk distribution despite women having a greater risk factor burden. Women with low socioeconomic status had the most adverse CVD risk profile.Conclusion
Despite women having a higher prevalence of CVD risk factors there was no sex difference in 10-year WHO/ISH CVD risk in Jamaican adults. 相似文献8.

Numerous studies have consistently shown an association between blunted sleep-time relative blood pressure (BP) decline (non-dipping) and increased cardiovascular disease (CVD) risk in hypertension. Normotensive persons with a non-dipper BP profile also have increased target organ damage, namely, increased left ventricular mass and relative wall thickness, reduced myocardial diastolic function, increased urinary albumin excretion, increased prevalence of diabetic retinopathy, and impaired glucose tolerance. It remains a point of contention, however, whether the non-dipper BP pattern or just elevated BP, alone, is the most important predictor of advanced target organ damage and future CVD events. Accordingly, we investigated the role of dipping status and ambulatory BP level as contributing factors for CVD morbidity and mortality in the MAPEC (Monitorización Ambulatoria para Predicción de Eventos Cardiovasculares, i.e., Ambulatory Blood Pressure Monitoring for Prediction of Cardiovascular Events) study. We prospectively studied 3344 individuals (1718 men/1626 women), 52.6?±?14.5 (mean?±?SD) yrs of age, during a median follow-up of 5.6 yrs. BP was measured by ambulatory monitoring (ABPM) for 48?h at baseline, and again annually or more frequently (quarterly) if treatment adjustment was required in treated hypertensive patients. At baseline, those with ABPM-substantiated hypertension were randomized to one of two treatment-time regimen groups: (i) ingestion of all prescribed hypertension medications upon awakening or (ii) ingestion of the entire dose of ≥1 of them at bedtime. Those found to be normotensive at baseline were untreated but followed and evaluated by repeated ABPM like the hypertensive patients. Participants were divided into four investigated categories on the basis of dipping status and ambulatory BP: (i) dipper vs. non-dipper, and (ii) normal ambulatory BP if the awake systolic (SBP)/diastolic (DBP) BP means were <135/85?mm Hg and the asleep SBP/DBP means were <120/70?mm Hg, and elevated ambulatory BP otherwise. Cox survival analyses, adjusted for significant confounding variables, documented that non-dippers had significantly higher CVD risk than dippers, whether they had normal (p?=?.017) or elevated ambulatory BP (p?<?.001). Non-dippers with normal awake and asleep SBP and DBP means, who accounted for 21% of the studied population, had similar hazard ratio (HR) of CVD events (1.61 [95% confidence interval, CI: 1.09–2.37]) as dippers with elevated ambulatory BP (HR: 1.54 [95% CI: 1.01–2.36]; p?=?.912 between groups). These results remained mainly unchanged for treated and untreated patients analyzed separately. Our findings document that the risk of CVD events is influenced not only by ambulatory BP elevation, but also by blunted nighttime BP decline, even within the normotensive range, thus supporting ABPM as a requirement for proper CVD risk assessment in the general population. The elevated CVD risk in “normotensive” individuals with a non-dipper BP profile represents a clear paradox, as those persons do not have “normal BP” or low CVD risk. Our findings also indicate the need to redefine the concepts of normotension/hypertension, so far established on the unique basis of BP level, mainly if not exclusively measured at the clinic, independently of circadian BP pattern.

The rs9939609 SNP located in the first intron of the fat mass and obesity associated gene (FTO) has been found to be associated with common obesity mainly in populations of European descent. The Roma/Gypsy population as an ethnic minority of Asian Indian origin is well known for its adverse health status with a high prevalence of obesity. The main aim of this study was to examine the contribution of the rs9939609 FTO polymorphism to the high prevalence of obesity in the Roma/Gypsy population. Following a number of anthropometric measurements, the FTO rs9939609 polymorphism was genotyped in 312 Roma/Gypsy individuals. We observed significant differences in body mass index (BMI), waist circumference, and waist-to-hip ratio between different genotypes (P = 0.003, P = 0.012, and P = 0.03, respectively). The waist circumference in the subjects with AA genotype was about 7.1 cm larger than in those with TT genotypes (P = 0.005). However, the strongest association of minor allele A of the rs9939609 FTO polymorphism was found with BMI (odds ratio, 1.55; 95% confidence interval, 1.129-2.128; P = 0.007), even after adjusting for age, sex, and smoking status. This study provides the first report of allele and genotype frequencies for the rs9939609 polymorphism and also the first evidence of the association of the FTO variant with obesity in the Roma/Gypsy population. 相似文献

The aim of study was to compare the impact of coronary risk factors on the incidence of acute myocardial infarction (MI) between Croatia, Central and Eastern Europe, and the rest of the world. As a part of the large international INTERHEART case-control study of acute MI in 52 countries (15,152 cases and 14,820 controls) we have investigated the relationship between several known risk factors (smoking, history of hypertension or diabetes, waist/hip ratio, dietary patterns, physical activity, consumption of alcohol, blood apolipoproteins, and psychosocial factors) and MI among patients without previously known coronary heart disease in Southern Croatia. The main identified MI risk factors in Southern Croatia were heavy smoking (>20 cig/day; OR 3.86; 95% CI 2.31-6.46), diabetes mellitus (OR 2.83; 95% CI 1.58-5.23), abnormal ratio of B-100 and A-1 apolipoproteins (OR 2.23; 95% CI 1.28-3.89), elevated waist to hip ratio (OR 1.96; 95% CI 1.21-3.18), and arterial hypertension (OR 1.68; 95% CI 1.15-2.45). Protective was moderate alcohol consumption (OR 0.63; 95% CI 0.40-0.99). The prevalence of major MI risk factors in Croatia is similar to that in the surrounding countries and in the world, accounting for over 90% of the population attributable risk. However, physical activity, dietary and psychosocial factors are seemingly less important in this country, while moderate alcohol consumption is more protective than regionally or globally. 相似文献

Background
Surveys measuring effectiveness of public awareness campaigns in reducing cardiovascular disease (CVD) incidence have yielded equivocal findings. The aim of this study was to describe cardiovascular risk factors (CVRFs) changes over the years in an untreated population-based study.Methods
Between 2007 and 2012, we conducted a screening campaign for CVRFs in men aged 40 to 65 yrs and women aged 50 to 70 yrs in the western suburbs of Paris. Data were complete for 20,324 participants of which 14,709 were untreated.Results
The prevalence trend over six years was statistically significant for hypertension in men from 25.9% in 2007 to 21.1% in 2012 (p=0.002) and from 23% in 2007 to 12.7% in 2012 in women (p<0.0001). The prevalence trend of tobacco smoking decreased from 38.6% to 27.7% in men (p=0.0001) and from 22.6% to 16.8% in women (p=0.113). The Framingham 10-year risk for CVD decreased from 13.3 ± 8.2 % in 2007 to 11.7 ± 9.0 % in 2012 in men and from 8.0 ± 4.1 % to 5.9 ± 3.4 % in women. The 10-year risk of fatal CVD based on the European Systematic COronary Risk Evaluation (SCORE) decreased in men and in women (p <0.0001).Conclusions
Over a 6-year period, several CVRFs have decreased in our screening campaign, leading to decrease in the 10-year risk for CVD and the 10-year risk of fatal CVD. Cardiologists should recognize the importance of community prevention programs and communication policies, particularly tobacco control and healthier diets to decrease the CVRFs in the general population. 相似文献12.
Risk factors for cardiovascular disease (CVD), such as obesity, diabetes, hypertension and physical inactivity, are common in Australia, but the prevalence varies according to cultural background. We examined the relationship between region of birth, measures of acculturation, and CVD risk profiles in immigrant, compared to Australian-born, older Australians. Cross-sectional data from 263,356 participants aged 45 and over joining the population-based 45 and Up Study cohort from 2006–2008 were used. Prevalence ratios for CVD risk factors in Australian- versus overseas-born participants were calculated using modified Poisson regression, adjusting for age, sex and socioeconomic factors and focusing on Asian migrants. The association between time resident in Australia and age at migration and CVD risk factors in Asian migrants was also examined. Migrants from Northeast (n = 3,213) and Southeast Asia (n = 3,942) had lower levels of overweight/obesity, physical activity and female smoking than Australian-born participants (n = 199,356), although differences in prevalence of overweight/obesity were sensitive to body-mass-index cut-offs used. Compared to Australian-born participants, migrants from Northeast Asia were 20–30% less likely, and from Southeast Asia 10–20% more likely, to report being treated for hypertension and/or hypercholesterolaemia; Southeast Asian migrants were 40–60% more likely to report diabetes. Northeast Asian-born individuals were less likely than Australian-born to have 3 or more CVD risk factors. Diabetes, treated hypertension and hypercholesterolaemia occurred at relatively low average body-mass-index in Southeast Asian migrants. The CVD risk factor profiles of migrants tended to approximate those of Australian-born with increasing acculturation, in both favourable (e.g., increased physical activity) and unfavourable directions (e.g., increased female smoking). Minimizing CVD risk in migrant populations may be achieved through efforts to retain the healthy facets of the traditional lifestyle, such as a normal body mass index and low prevalence of smoking in women, in addition to adopting healthy aspects of the host country lifestyle, such as increased physical activity. 相似文献

ABSTRACT: BACKGROUND: Arterial hypertension (AH) is a main risk factor for the risk from cardiovascular (CVD) and stroke mortality. Only few data was published on prevalence, awareness and management of AH in Lithuania. Development of objective approaches to the treatment and control of AH reduces the risk of mortality. The aim of this study was to evaluate time trends, the prevalence, awareness, treatment and control of AH and risk of mortality among Lithuanian urban population aged 45--64 years during the period of 1983--2009. METHODS: Time trends of AH and risk of mortality were examined in three MONICA health surveys in 1983, 1986, 1992, and in one health survey according to MONICA protocol in 2002 included randomly recruited of 2,218 men and 2,491 women. AH was defined as systolic blood pressure (BP) [GREATER-THAN OR EQUAL TO]140 mmHg and/or diastolic BP of [GREATER-THAN OR EQUAL TO]90 mmHg or current use of antihypertensive medication. The main outcome measures were all-cause mortality, mortality from CVD, coronary heart disease (CHD) and stroke. The mean duration of follow-up was 11.8 [PLUS-MINUS SIGN] 9.2 years. All survey periods were age standardized to the year 2006 of Kaunas population. The estimates of hazard ratio and 95% confidence interval were based on the multivariate Cox proportional hazards regression. RESULTS: In men during 1983--2002 period hypertension prevalence was 52.1--58.7% and did not significantly change whereas in women decreased from 61.0 to 51.0%. There was a significant increase in hypertension awareness among hypertensive men and women (45.0 to 64.4% and 47.7 to 72.3%, respectively) and in treated hypertensives (55.4 to 68.3% in men and 65.6 to 86.2% in women). Adjusted Cox proportional hazard regression analyses revealed a strong dose--response association between blood-pressure level and all-cause, CVD, CHD and stroke-mortality risk in both men and women groups. CONCLUSION: In Lithuanian urban population the prevalence of hypertension remains high. Despite positive changes in hypertension awareness and treatment, hypertension control remains poor. A strong dose--response association between the level of BP and all-cause, CVD, CHD and stroke mortality risk was indicated. 相似文献

The Bayash are a branch of Romanian speaking Roma living dispersedly in Central, Eastern, and Southeastern Europe. To better understand the molecular architecture and origin of the Croatian Bayash paternal gene pool, 151 Bayash Y chromosomes were analyzed for 16 SNPs and 17 STRs and compared with European Romani and non-Romani majority populations from Europe, Turkey, and South Asia. Two main layers of Bayash paternal gene pool were identified: ancestral (Indian) and recent (European). The reduced diversity and expansion signals of H1a patrilineages imply descent from closely related paternal ancestors who could have settled in the Indian subcontinent, possibly as early as between the eighth and tenth centuries AD. The recent layer of the Bayash paternal pool is dominated by a specific subset of E1b1b1a lineages that are not found in the Balkan majority populations. At least two private mutational events occurred in the Bayash during their migrations from the southern Balkans toward Romania. Additional admixture, evident in the low frequencies of typical European haplogroups, J2, R1a, I1, R1b1b2, G, and I2a, took place primarily during the early Bayash settlement in the Balkans and the Romani bondage in Romania. Our results indicate two phenomena in the Bayash and analyzed Roma: a significant preservation of ancestral H1a haplotypes as a result of considerable, but variable level of endogamy and isolation and differential distribution of less frequent, but typical European lineages due to different patterns of the early demographic history in Europe marked by differential admixture and genetic drift. 相似文献

OBJECTIVES: Only 193 people from Pitcairn Island, all descended from 9 'Bounty' mutineers and 12 Tahitian women, moved to the uninhabited Norfolk Island in 1856. Our objective was to assess the population of Norfolk Island, several thousand km off the eastern coast of Australia, as a genetic isolate of potential use for cardiovascular disease (CVD) gene mapping. METHODS: A total of 602 participants, approximately two thirds of the island's present adult population, were characterized for a panel of CVD risk factors. Statistical power and heritability were calculated. RESULTS: Norfolk Islander's possess an increased prevalence of hypertension, obesity and multiple CVD risk factors when compared to outbred Caucasian populations. 64% of the study participants were descendents of the island's original founder population. Triglycerides, cholesterol, and blood pressures all had heritabilities above 0.2. CONCLUSIONS: The Norfolk Island population is a potentially useful genetic isolate for gene mapping studies aimed at identifying CVD risk factor quantitative trait loci (QTL). 相似文献

The sex difference in the prevalence rates of diabetes and cardiovascular diseases (CVDs) among the middle-aged population in China remain largely unknown. Therefore, we analyzed differences in the prevalence of diabetes, self-reported CVDs, and some CVD risk factors among men and women in the middle-aged population (30–49 years) and in individuals aged 50 years and older using data from the China National Diabetes and Metabolic Disorders Study of 2007–2008. Middle-aged men appeared to have significantly a higher prevalence of diabetes and self-reported CVDs than middle-aged women (8.07% vs 5.06% for diabetes, P < 0.001; 0.64% vs 0.22% for CVDs, P < 0.001). Men also showed higher rates of central obesity, hypertension, and dyslipidemia than women (all P < 0.01). Compared with women, men were more likely to drink alcohol and smoke cigarettes but less likely to be under diet control. The sex-specific differences in prediabetes, CVD, and CVD risk factors between men and women were diminished or even reversed in the population aged 50 years and older. No sex-specific differences were found in the prevalences of a family history of diabetes, coronary heart disease, and hypertension (P > 0.05) in middle-aged population. Specific strategies to reduce modifiable risk factors for the prevention and control of diabetes and CVD may be warranted in this population. 相似文献

The burden of cardiovascular risk associated with obesity disproportionately affects African Americans and little is known about ethnic/racial differences in the relationship of obesity to cardiometabolic risk. This report assesses whether obesity is similarly associated with cardiometabolic risk factors in African Americans and whites of European ancestry. Cross‐sectional observational data from the Jackson Heart Study (JHS) and the Framingham Heart Study (FHS) were compared. This analysis uses participants aged 35–74 years with BMI >18.5 kg/m2, and free of prevalent cardiovascular disease (CVD), from the initial JHS clinical examination (2000–2004) and the FHS Offspring (1998–2001) and Third Generation (2002–2005) cohorts. Participants were evaluated for the presence of lipid abnormalities, hypertension, and diabetes. Overall, 4,030 JHS (mean age 54 years, 64% women) and 5,245 FHS (mean age 51 years, 54% women) participants were available for analysis. The prevalence of all risk factors except high triglycerides and low high‐density lipoprotein (HDL) was substantially higher in JHS (all P < 0.001) and BMI was associated with increasing prevalence of most CVD risk factors within each race. For diabetes mellitus, hypertension, and low HDL, steeper relationships to BMI were observed in FHS than in JHS (P values <0.001–0.016). There were larger proportional increases in risk factor prevalence with increasing BMI in whites than in African Americans. The higher prevalence rates of cardiometabolic risk factors at nearly all levels of BMI in African Americans, however, suggest that additional factors contribute to the burden of CVD risk in African Americans. 相似文献

Background
Previous studies indicated that lifestyle-related cardiovascular risk factors tend to be clustered in certain individuals. However, population-based studies, especially from developing countries with substantial economic heterogeneity, are extremely limited. Our study provides updated data on the clustering of cardiovascular risk factors, as well as the impact of lifestyle on those factors in China.Methods
A representative sample of adult population in China was obtained using a multistage, stratified sampling method. We investigated the clustering of four cardiovascular disease (CVD) risk factors (defined as two or more of the following: hypertension, diabetes, dyslipidemia and overweight) and their association with unhealthy lifestyles (habitual drinking, physical inactivity, chronic use of non-steroidal anti-inflammatory drugs (NSAIDs) and a low modified Dietary Approaches to Stop Hypertension (DASH) score).Results
Among the 46,683 participants enrolled in this study, only 31.1% were free of any pre-defined CVD risk factor. A total of 20,292 subjects had clustering of CVD risk factors, and 83.5% of them were younger than 65 years old. The adjusted prevalence of CVD risk factor clustering was 36.2%, and the prevalence was higher among males than among females (37.9% vs. 34.5%). Habitual drinking, physical inactivity, and chronic use of NSAIDs were positively associated with the clustering of CVD risk factors, with ORs of 1.60 (95% confidence interval [CI] 1.40 to1.85), 1.20 (95%CI 1.11 to 1.30) and 2.17 (95%CI 1.84 to 2.55), respectively. The modified DASH score was inversely associated with the clustering of CVD risk factors, with an OR of 0.73 (95%CI 0.67 to 0.78) for those with modified DASH scores in the top tertile. The lifestyle risk factors were more prominent among participants with low socioeconomic status.Conclusion
Clustering of CVD risk factors was common in China. Lifestyle modification might be an effective strategy to control CVD risk factors. 相似文献19.

In resistant hypertension, ingesting one or more blood pressure (BP)-lowering medications at bedtime is associated with significant reduction of sleep-time BP, a sensitive prognostic marker of cardiovascular disease (CVD) risk. This randomized trial investigated if bedtime therapy with at least one hypertension medication exerts better BP control and CVD risk reduction than conventional, morning-time therapy with all medications. We conducted a prospective, open-label, blinded-endpoint trial on 776 patients (387 men/389 women) with resistant hypertension, 61.6?±?11.2 (mean?±?SD) yrs of age. Patients were randomized to ingest all their prescribed hypertension medications upon awakening or ≥1 of them at bedtime. BP was measured by ambulatory monitoring for 48?h at baseline, and again annually or more frequently (quarterly) if treatment adjustment was required. After a median follow-up of 5.4 yrs (range, .5–8.5 yrs), participants ingesting ≥1 hypertension medications at bedtime showed a significantly lower hazard ratio (HR) of total CVD events (adjusted by age, sex, and diabetes) than those ingesting all medications upon awakening (.38 [95% CI: .27–.55]; number of events 102 vs. 41; p?<?.001). The difference between groups in the adjusted HR of major CVD events (a composite of CVD death, myocardial infarction, ischemic stroke, and hemorrhagic stroke) was also statistically significant (.35 [95% CI: .18–.68]; number of events 32 vs. 12; p?=?.002). At the last evaluation, patients treated with the bedtime versus awakening-time-treatment regimen showed significantly lower sleep-time systolic/diastolic BP mean values (121.6/65.4 vs. 113.0/61.1?mm Hg; p?<?.001) and higher prevalence of controlled ambulatory BP (61% vs. 46%; p?<?.001). The progressive decrease in the sleep-time systolic BP mean during follow-up was the most significant predictor of event-free survival (15% risk reduction per 5?mm Hg decreased asleep systolic BP mean). Among patients with resistant hypertension, ingestion of at least one hypertension medication at bedtime, compared with all medications upon waking, resulted in improved ambulatory BP control and fewer hard and soft CVD events.
