Alcohol consumption, metabolic cardiovascular risk factors and hypertension in women

BACKGROUND: Low to moderate alcohol consumption is associated with reduced mortality, primarily due to a reduction in coronary heart disease (CHD). Conversely, heavy drinking increases mortality, mainly due to haemorrhagic stroke and non-cardiovascular diseases. It is important to identify the threshold of alcohol consumption above which the balance of risk and benefit becomes adverse. We examine the relationship between reported alcohol consumption, cardiovascular disease (CVD) risk factors, a 10-year CHD risk score and hypertension in women. METHODS: In all, 14 077 female employees aged 30-64 years, underwent screening for CVD risk factors. Information was available on a range of personal and lifestyle factors, including height, weight, blood pressure, lipids, lipoproteins, apolipoproteins and blood glucose. Age-adjusted means were computed for the risk factors in each of five groups of reported alcohol intake: <1 (non-drinkers), 1-7, 8-14, 15-21, > or = 22 units/week. The relationships between alcohol and a derived coronary risk score and hypertension were also examined. RESULTS: Increasing consumption was associated with an age-adjusted increase in high density lipoprotein cholesterol (HDL-C) and apolipoprotein A1 (both P < 0.001), a decline in body mass index, total cholesterol (TC), TC/HDL-C ratio, low density lipoprotein cholesterol (LDL-C) and apolipoprotein B (all P < 0.001), and no trend in triglycerides (P = 0.06), lipoprotein (a) (P = 0.09) or fasting glucose (P = 0.14). Except for LDL-C (P = 0.06) the relationships remained statistically significant after adjustment for possible confounders. Compared to non-drinkers, there was a decrease in 10-year CHD risk with increasing consumption, with the greatest reduction in risk in women consuming 1-7 units/week, odds ratio (OR) = 0.79, (95% CI: 0.72-0.87), and an increase in the prevalence of hypertension among those consuming 15-21 units/week, OR = 1.68, (95% CI: 1.14-2.46). CONCLUSIONS: This study provides biological support for an inverse association between alcohol intake and CHD in women, associated with favourable changes in lipid and lipoprotein risk factors. Women consuming 1-14 units/week had a reduction in CHD risk, but there was an increased prevalence of hypertension among those consuming > or = 15 units/week. These data suggest that, in terms of the reduced risk of CVD, women should be advised to restrict their alcohol consumption to < or = 14 units/week.     

浙江海岛渔民人群吸烟、饮酒与高脂血症的关系

目的 探讨渔民人群吸烟、饮酒与高胆固醇血症、高甘油三酯血症之间的关系。方法应用现况调查结合病例对照研究的方法，随机抽取115名海岛渔民，按血脂检测结果分为病例组和对照组。采用流行病学问卷调查表的形式，详细调查其个人一般情况及吸烟、饮酒史，用单因素及其统计学分析方法比较吸烟(饮酒)组与对照组间脂蛋白和载脂蛋白(apo)水平差异及吸烟和饮酒对高脂血症的OR值。结果 吸烟组的OR值为3．417(95％CI：1．132～10．308)，吸烟指数与高脂血症患病具有明显的剂量效应关系，吸烟组低密度脂蛋白胆固醇(LDL—C)和apoB的水平高于对照组。开始饮酒年龄≤20岁及年饮酒精量≥15000m者，对高脂血症的oR值分别为4．016(95％CI：1．475～10．952)及3．275(95％CI：1．249～8．580)，酗酒渔民LDL—C、apoB、总胆固醇(TC)／高密度脂蛋白胆固醇(HDL—C)水平高于对照组，吸烟且饮酒者其OR值高于单吸烟或单饮酒者。结论 吸烟和酗酒是高脂血症的重要危险因素，其主要通过影响LDL—C、apoB水平导致高脂血症发生。吸烟及酗酒对高脂血症的发生具有协同作用。     

Cheese consumption in relation to cardiovascular risk factors among Iranian adults- IHHP Study

BACKGROUND/OBJECTIVE

It is expected that dairy products such as cheeses, which are the main source of cholesterol and saturated fat, may lead to the development or increase the risk of cardiovascular and metabolic diseases; however, the results of different studies are inconsistent. This study was conducted to assess the association between cheese consumption and cardiovascular risk factors in an Iranian adult population.

SUBJECTS/METHODS

Information from the Isfahan Healthy Heart Program (IHHP) was used for this cross-sectional study with a total of 1,752 participants (782 men and 970 women). Weight, height, waist and hip circumference measurement, as well as fasting blood samples were gathered and biochemical assessments were done. To evaluate the dietary intakes of participants a validated food frequency questionnaire, consists of 49 items, was completed by expert technicians. Consumption of cheese was classified as less than 7 times per week and 7-14 times per week.

RESULTS

Higher consumption of cheese was associated with higher C-Reactive Protein (CRP), apolipoprotein A and high density lipoprotein cholesterol (HDL-C) level but not with fasting blood sugar (FBS), total cholesterol, low density lipoprotein cholesterol (LDL-C), triglyceride (TG) and apolipoprotein B. Higher consumption of cheese was positively associated with consumption of liquid and solid oil, grain, pulses, fruit, vegetable, meat and dairy, and negatively associated with Global Dietary Index. After control for other potential confounders the association between cheese intake and metabolic syndrome (OR: 0.81; 96%CI: 0.71-0.94), low HDL-C level (OR: 0.87; 96%CI: 0.79-0.96) and dyslipidemia (OR: 0.88; 96%CI: 0.79-0.98) became negatively significant.

CONCLUSION

This study found an inverse association between the frequency of cheese intake and cardiovascular risk factors; however, further prospective studies are required to confirm the present results and to illustrate its mechanisms.     

Lipoprotein profile and prevalence of cardiovascular risk factors in urban Moroccan women

OBJECTIVE: The study aimed to characterize the lipid and apolipoprotein profile and the prevalence of cardiovascular risk factors in a population of urban adult women of Morocco. DESIGN: A total of 213 women 25-55 y old were sampled from an agricultural province of Morocco: El Jadida. The following parameters of lipid and apolipoprotein profile were measured: plasma triglycerides (TG), plasma cholesterol (TC), triglyceride-rich lipoprotein triglycerides (TRL-TG), TRL-cholesterol (TRL-C), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and apolipoproteins A1, B, B48, CIII and E. Waist circumference (WC), body mass index (BMI) and blood pressure (BP) were also determined. RESULTS: The women studied showed the following pattern: elevated TC, LDL-C levels and TC/HDL-C in 10, 19.4 and in 43.8%, respectively; low HDL-C levels in 45.3% (<0.9 mmol/l) or in 95% (when the cutoff <1.3 mmol/l is used), elevated TG levels in 11.8%. Elevated TRL-C (>0.6 mmol/l) and TRL-TG (>0.8 mmol/l) were observed in 13.4%. Obesity and hypertension were highly prevalent in 23.9 and 16.5%, respectively. Plasma triglyceride concentrations were closely correlated with plasma concentrations of TRL-TG (R = 0.86, P = 0.0001), apoB (R = 0.50, P = 0.0001) and apoCIII (R = 0.52, P = 0.0001) and moderately correlated with HDL-C levels (R = -0.3, P = 0.0001) and BMI (R = 0.4, P = 0.0001). The association between BMI and systolic blood pressure was statistically significant (R = 0.3, P = 0.0001). Obesity, BP, TRL-C, TRL-TG, TG, apoB and apoCIII increased with age. CONCLUSION: There is a high prevalence of some risk factors for cardiovascular disease including altered lipid and lipoprotein profiles in the Moroccan urban women studied, some of these risk factors are associated with age.

Prospective associations between serum biomarkers of lipid metabolism and overall,breast and prostate cancer risk

Experimental studies provided evidence about mechanisms by which cholesterol, especially high density lipoprotein cholesterol (HDL-C), could influence carcinogenesis, notably through antioxidant and anti-inflammatory properties. However, prospective studies that investigated the associations between specific lipid metabolism biomarkers and cancer risk provided inconsistent results. The objective was to investigate the prospective associations between total cholesterol (T-C), HDL-C, low density lipoprotein cholesterol, apolipoproteins A1 (apoA1) and B, and triglycerides and overall, breast and prostate cancer risk. Analyses were performed on 7,557 subjects of the Supplémentation en Vitamines et Minéraux Antioxydants Study, a nationwide French cohort study. Biomarkers of lipid metabolism were measured at baseline and analyzed regarding the risk of first primary incident cancer (N = 514 cases diagnosed during follow-up, 1994–2007), using Cox proportional hazards models. T-C was inversely associated with overall (HR_{1mmol/L increment} = 0.91, 95 % CI 0.82–1.00; P = 0.04) and breast (HR_{1mmol/L increment} = 0.83, 95 % CI 0.69–0.99; P = 0.04) cancer risk. HDL-C was also inversely associated with overall (HR_{1mmol/L increment} = 0.61, 95 % CI 0.46–0.82; P = 0.0008) and breast (HR_{1mmol/L increment} = 0.48, 95 % CI 0.28–0.83; P = 0.009) cancer risk. Consistently, apoA1 was inversely associated with overall (HR_{1g/L increment} = 0.56, 95 % CI 0.39–0.82; P = 0.003) and breast (HR_{1g/L increment} = 0.36, 95 % CI 0.18–0.73; P = 0.004) cancer risk. This prospective study suggests that pre-diagnostic serum levels of T-C, HDL-C and ApoA1 are associated with decreased overall and breast cancer risk. The confirmation of a role of cholesterol components in cancer development, by further large prospective and experimental studies, may have important implications in terms of public health, since cholesterol is already crucial in cardiovascular prevention.
