Association between sucrose intake and acute coronary event risk and effect modification by lifestyle factors: Malmö Diet and Cancer Cohort Study.

Previous studies have suggested that a high intake of sugar-sweetened beverages is positively associated with the risk of a coronary event. However, a few studies have examined the association between sucrose (the most common extrinsic sugar in Sweden) and incident coronary events. The objective of the present study was to examine the associations between sucrose intake and coronary event risk and to determine whether these associations are specific to certain subgroups of the population (i.e. according to physical activity, obesity status, educational level, alcohol consumption, smoking habits, intake of fat and intake of fruits and vegetables). We performed a prospective analysis on 26 190 individuals (62 % women) free from diabetes and without a history of CVD from the Swedish population-based Malmö Diet and Cancer cohort. Over an average of 17 years of follow-up (457 131 person-years), 2493 incident cases of coronary events were identified. Sucrose intake was obtained from an interview-based diet history method, including 7-d records of prepared meals and cold beverages and a 168-item diet questionnaire covering other foods. Participants who consumed >15 % of their energy intake (E%) from sucrose showed a 37 (95 % CI 13, 66) % increased risk of a coronary event compared with the lowest sucrose consumers (<5 E%) after adjusting for potential confounders. The association was not modified by the selected lifestyle factors. The results indicated that sucrose consumption higher than 15 E% (5 % of this population) is associated with an increased risk of a coronary event.

Food patterns, inflammation markers and incidence of cardiovascular disease: the Malmö Diet and Cancer study.

OBJECTIVES: To examine the associations between food patterns constructed using cluster analysis and markers of systemic and vascular inflammation, and incident cardiovascular disease (CVD) after 13 years of follow-up. DESIGN: Population-based, prospective cohort study. SETTING AND SUBJECTS: Cluster analysis identified six food patterns from 43 food group variables among 4999 subjects, aged 45-68 years, who participated in the Malmö Diet and Cancer cardiovascular programme between 1991 and 1994. Lipoprotein-associated phospholipase A(2) (Lp-PLA(2) ), C-reactive protein concentration and white blood cell (WBC) count were measured using blood samples at baseline. Incidence of CVD (coronary events and ischaemic stroke) was monitored over 13 years of follow-up. RESULTS: The fibre-rich bread pattern was associated with favourable effects on WBC count in women, and the low-fat and high-fibre pattern with favourable effects on Lp-PLA(2) mass in women, and on Lp-PLA(2) activity in men. However, the milk fat and sweets and cakes patterns were both associated with adverse effects; the former on WBC count in women and on Lp-PLA(2) mass in men, and the latter on WBC count and Lp-PLA(2) mass in women. The milk fat and sweets and cakes patterns were associated with increased CVD risk in women. CONCLUSIONS: The results of this study support the present Nordic dietary recommendations indicating that diets rich in high-fibre, low-fat and low-sugar foods are favourably associated with markers of inflammation and, potentially, with CVD risk.

A prospective Swedish study on body size, body composition, diabetes, and prostate cancer risk.

Obesity may be associated with increased risk of prostate cancer (PCa). According to one hypothesis, obesity could lower the risk of non-aggressive tumours, while simultaneously increasing the risk of aggressive cancer. Furthermore, central adiposity may be independently associated with PCa risk; it is also associated with diabetes, which itself may influence risk of PCa. We studied the associations between height, body composition, and fat distribution, diabetes prevalence and risk of total, aggressive, and non-aggressive PCa in 10,564 initially cancer-free men (aged 45-73 years) of the population-based Malmö Diet and Cancer cohort. Anthropometric and body composition measurements, including bioelectrical impedance for estimation of fat mass, were performed by study nurses. Diabetes prevalence was self-reported. Cancer cases and clinical characteristics were ascertained through national and regional registry data. Dietary and other background data were obtained through a modified diet history method and an extensive questionnaire. During a mean follow-up of 11.0 years, 817 incidental PCa cases were diagnosed. Of these, 281 were classified as aggressive. There were 202 cases occurring before 65 years of age. Height was positively associated with total and non-aggressive PCa risk. Waist-hip ratio (WHR), a measure of central adiposity, was positively associated with PCa before age 65, and less strongly, with total PCa. This association was independent of body mass index (BMI) and other potential confounders. General adiposity, expressed as BMI or body fat percentage, and prevalent diabetes were not associated with PCa risk. In this study, WHR and body height were stronger PCa predictors than general adiposity.

Serum concentrations of beta-carotene and alpha-tocopherol are associated with diet, smoking, and general and central adiposity.

BACKGROUND: Previous studies of associations between diet, obesity, and blood concentrations of alpha-tocopherol and beta-carotene have been equivocal. Furthermore, most studies used only body mass index (BMI) as an obesity measure. OBJECTIVES: Our objectives were to examine the associations between energy and nutrient intakes, alcohol consumption, tobacco use, and serum cholesterol and serum concentrations of alpha-tocopherol and beta-carotene, and to examine the associations between different measures of general and central adiposity and serum concentrations of alpha-tocopherol and beta-carotene. DESIGN: This was a cross-sectional, population-based study of 253 men and 276 women aged 46-67 y. Nutrient data were collected by a modified diet history method. Measures of obesity included BMI, percentage of body fat (impedance analysis), waist-to-hip ratio, and waist circumference. The associations between serum nutrient concentrations and the other factors were examined by multiple linear regression. RESULTS: Twenty-one percent of men and 34% of women used antioxidant supplements. The mean BMI was 26.1 in men and 25.4 in women. Serum beta-carotene concentration was positively associated with serum cholesterol concentration, fiber intake, and beta-carotene intake, and negatively associated with smoking and all measures of obesity. In men, serum beta-carotene concentration was not significantly associated with central adiposity after adjustment for body fat. Serum alpha-tocopherol concentration was positively correlated with serum cholesterol, obesity, and vitamin E intake. In women, serum alpha-tocopherol concentration was also positively associated with intakes of ascorbic acid and selenium. Serum alpha-tocopherol concentration was associated with central adiposity after adjustment for body fat. CONCLUSION: Serum beta-carotene and alpha-tocopherol concentrations have different associations with diet, smoking, general adiposity, and central adiposity.

The prevalence of anaemia and mineral supplement use in a Swedish middle-aged population. Results from the Malmö Diet and Cancer Study.

OBJECTIVE: To describe dietary habits and use of mineral supplements in relation to nutrient recommendations and anaemia. DESIGN: a population-based cohort study. SUBJECTS: 2665 men and 3878 women, born between 1926 and 1945, randomly invited and participating in the prospective 'Malmö Diet and Cancer study' during 1991-1992. METHODS: The diet was assessed using a combined 7-day menu book for hot meals, beverages and supplements and a quantitative food frequency questionnaire for other foods. Anaemia was defined as haemoglobin < or = 131 g/l for men and < or = 115 g/l for women. RESULTS: Intake of mineral supplements were reported by 19% of the men and 31% of the women. Less than 0.2% had intakes of iron and selenium above highest recommended Swedish long-term intakes. The percentage of women with intake below nutrient recommendations were: zinc and selenium (60%); magnesium (35%); calcium (21%) and iron (70%, premenopausal). The corresponding values for men were: zinc, selenium and magnesium (33-47%); calcium and iron (5%). The median contribution of calcium from supplements was less than 110 mg. Supplement users had higher intakes of fish, fruits, vegetables and tea and lower intakes of coffee and meat. The iron intake was correlated to haemoglobin levels, and iron supplementation constituted about 45% of the intake. Three per cent of premenopausal women had anaemia as did less than 2% of postmenopausal women. CONCLUSION: A substantial number had mineral intake below present recommendations despite supplement use. The nutrient content of some supplements could be improved, especially calcium. Iron supplementation among postmenopausal women and men are questionable.

Measures of birth size in relation to risk of prostate cancer: the Malmö Diet and Cancer Study, Sweden.

There is some evidence that perinatal factors, specifically birth weight (BW), may be related to the onset of prostate cancer (PRCA). This case-control study, nested within the Malmö Diet and Cancer Cohort Study, used archived birth record data from 308 incident PRCA cases diagnosed between 1991 and 2005, and 637 age-matched controls among 4781 men born (1923-1945) in Malmö and Lund, Sweden. We applied conditional logistic regression to examine the birth size-PRCA association, including tumour subtypes, adjusting for perinatal and adult factors. Compared with controls, cases had a non-significantly higher mean BW and were more likely to have high (>4000 g) BW (21% v. 18%), but did not differ in other birth size measures, nor in mean adult body mass index . We observed a non-linear association between BW and PRCA risk. Compared with BWs between 3000 and 3500 g (reference), the fully adjusted odds ratios (OR, 95% CI) were 0.55 (0.33-0.91) for <3000 g, 0.86 (0.61-1.22) for 3500-4000 g and 0.98 (0.64-1.50) for >4000 g. Among men with aggressive tumours, the reduction in risk for those with BWs <3000 g (OR 0.26, 95% CI 0.09-0.72) was stronger than the rate of risk for PRCA overall. Crude risk estimates were minimally attenuated when adjusted for gestational age, maternal age, birth order and adult factors. Birth length, head circumference and placental weight were not associated with prostate cancer. Our results indicate a protective effect of lower BW on risk of total and aggressive prostate cancer, rather than any direct effect of larger birth size.

Alcohol consumption patterns, diet and body weight in 10 European countries.

BACKGROUND/OBJECTIVES: Europe has the highest level of alcohol consumption in the world. As drinking patterns are important determinants of the beneficial and harmful effects of alcohol consumption, we investigated alcohol consumption in relation to nutrient intake, place of consumption, education and body weight in a sample of adults from 10 European countries. METHODS: A 24-h dietary recall interview was conducted on 13 025 men and 23 009 women, aged 35-74 years, from 27 centres participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Means and standard errors of alcohol consumption, adjusted for age, were calculated, stratified by gender and centre. RESULTS: In many centres, higher level drinkers (males consuming >24 g of ethanol/day, equivalent to >2 standard drinks and females consuming >12 g of ethanol/day equivalent to >1 standard drink) obtained more energy from fat and protein and less from sugar than did abstainers. The proportion of energy from starch tended to be higher for male and lower for female higher level drinkers than for abstainers. Female higher level drinkers had a lower body mass index than did abstainers, whereas male higher level drinkers generally weighed more. Male higher level drinkers were less educated than abstainers in Mediterranean countries, but were more educated elsewhere. Female higher level drinkers were usually more educated than were abstainers. Outside the home, consumption (both genders) tended to be at friends' homes, particularly among men in Northern and Central Europe, and in bars in Spain. CONCLUSIONS: This study reveals clear geographical differences in drinking habits across Europe, and shows that the characteristics of different alcohol consumption categories also vary.

Dietary intakes of retinol, beta-carotene, vitamin D and vitamin E in the European Prospective Investigation into Cancer and Nutrition cohort.

OBJECTIVES: To describe the intake of the fat-soluble nutrients retinol, beta-carotene, vitamin E and vitamin D and their food sources among 27 redefined centres in 10 countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. METHODS: Between 1995 and 2000, 36,034 subjects (age range: 35-74 years) completed a single standardized 24-h dietary recall using a computerized interview software program (EPIC-SOFT). Intakes of the fat-soluble nutrients were estimated using the standardized EPIC Nutrient Database. RESULTS: For all the nutrients, in most centres, men had a higher level of intake than did women, even after adjustments for total energy intake and anthropometric confounders. Distinct regional gradients from northern to southern European countries were observed for all nutrients. The level intake of beta-carotene and vitamin E also showed some differences by level of education, smoking status and physical activity. No meaningful differences in the nutrient intake were observed by age range. CONCLUSIONS: These results show differences by study centre, gender, age and various lifestyle variables in the intake of retinol, beta-carotene, vitamin E and vitamin D between 10 European countries.

Use of dietary supplements in the European Prospective Investigation into Cancer and Nutrition calibration study.

BACKGROUND: Dietary supplement use is increasing, but there are few comparable data on supplement intakes and how they affect the nutrition and health of European consumers. The aim of this study was to describe the use of dietary supplements in subsamples of the 10 countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). METHODS: Specific questions on dietary supplement use were asked as a part of single 24-h recalls performed on 36,034 men and women aged 35-74 years from 1995 to 2000. RESULTS: Between countries, the mean percentage of dietary supplement use varied almost 10-fold among women and even more among men. There was a clear north-south gradient in use, with a higher consumption in northern countries. The lowest crude mean percentage of use was found in Greece (2.0% among men, 6.7% among women), and the highest was in Denmark (51.0% among men, 65.8% among women). Use was higher in women than in men. Vitamins, minerals or combinations of them were the predominant types of supplements reported, but there were striking differences between countries. CONCLUSIONS: This study indicates that there are wide variations in supplement use in Europe, which may affect individual and population nutrient intakes. The results underline the need to monitor consumption of dietary supplements in Europe, as well as to evaluate the risks and benefits.

Dietary habits after myocardial infarction - results from a cross-sectional study.

OBJECTIVE: Comparing habitual nutrient intakes in persons with a history of acute myocardial infarction (AMI), and age-matched controls. Design. Cross-sectional study. Subjects. Men and women (525 cases and 1890 matched controls), aged 47-73 years, of the population-based Malmö Diet and Cancer cohort. METHODS: Nutrient intakes were assessed by a validated modified diet history method. Body fatness was assessed by bioimpedance analysis. Case ascertainment was provided by national and regional registries. Men and women were analysed separately. Median time since AMI was 5.5 years in men and 3.8 years in women. Cases reported lower energy intakes (EIs) than controls, despite having similar basal metabolic rates. After adjustment for total EI, both male and female cases had lower fat intake and higher intake of several micronutrients, such as ascorbic acid, folate, and vitamin E, than controls, the difference being largest in men. Most of the cases reporting dietary change quoted 'disease' as their main reason for change. They had lower EI and lower energy-adjusted intake of fat than other cases. CONCLUSIONS: Survivors of AMI reported dietary habits more in line with current recommendations, particularly those who afterwards reported having changed their dietary habits. The possible bias introduced by social desirability is discussed.

Usage and users of natural remedies in a middle-aged population: demographic and psychosocial characteristics. Results from the Malmö Diet and Cancer Study.

BACKGROUND: In Sweden, large amounts of money are spent annually on natural remedies (NRs), in spite of the fact that most products in this category lack scientific documentation of their efficacy and side-effects. The usage and users of natural remedies are not well defined. This paper describes NR use and NR users in a city in southern Sweden, and tests the hypothesis that the use of natural remedies is a strategy for coping with psychosocial stressors. METHODS: The study cohort consisted of 6545 men and women, aged 45-65 years, who during 1991 and 1992 participated in the Malmö Diet and Cancer Study, a large-scale prospective cohort study. Data on consumption of natural remedies were recorded during seven consecutive days, as part of a dietary assessment. Each participant also completed a questionnaire, covering education, work history, alcohol and smoking habits, perceived health, and psychosocial factors such as social network, social support, job strain and global control. Body composition was also measured. RESULTS: The prevalence of NR consumption was 26% among women and 17% among men. NR use was most common during winter and spring. The most popular products were ginseng, garlic, and various herb and plant extracts. Important determinants of NR usage were higher education, Swedish origin, and lifestyle factors like low body weight fat percentage and high alcohol consumption among women. Other determinants were higher age and non-smoking among men. None of the psychosocial factors appeared to influence the prevalence of NR consumption. CONCLUSIONS: The prevalence of NR consumption is influenced by sex, demographic factors, season of the year, and lifestyle. Use of NRs does not appear to be a common strategy for coping with psychosocial stress.

Fruit and vegetable consumption in relation to risk factors for cancer: a report from the Malmö Diet and Cancer Study.

OBJECTIVE: To examine the associations between the consumption of fruit and vegetables and other markers of cancer risk. DESIGN: A cross-sectional survey within the population-based prospective Malmö Diet and Cancer (MDC) Study. Information on food habits was collected through the modified diet history method designed and validated for the MDC Study. Data on smoking and alcohol habits, leisure time physical activity, birth country, education, socioeconomic status and cohabitation status were collected through a questionnaire. SETTING: Malmö, the third largest city in Sweden. SUBJECTS: All subjects who entered the MDC Study during winter 1991 to summer 1994 (men and women living in Malmö, aged between 46 and 68 years), with a total of 15 173. RESULTS: Women consumed more fruit and vegetables than men. Low consumption of both fruits and vegetables was associated with unfavourable nutrient profiles: higher percentage of energy from fat and lower intakes of antioxidant nutrients and dietary fibre. Low consumption was also associated with smoking, low leisure time physical activity, low education and being born in Sweden. High age was associated with low vegetable consumption in both genders. CONCLUSION: This study indicates that several established risk markers and risk factors of cancer may be independently associated with low fruit and vegetable consumption. The findings suggest that the adverse effects of factors such as smoking, low physical activity and a high-fat diet could partly be explained by low consumption of fruit or vegetables. The implied health benefits of a low or moderate alcohol consumption may be similarly confounded by high consumption of fruit or vegetables.

Consumption of vegetables, fruit and other plant foods in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohorts from 10 European countries.

OBJECTIVE: To describe and compare the consumption of the main groups and sub-groups of vegetables and fruits (V&F) in men and women from the centres participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). DESIGN: Cross-sectional analysis. Dietary intake was assessed by means of a 24-hour dietary recall using computerised interview software and standardised procedures. Crude and adjusted means were computed for the main groups and sub-groups of V&F by centre, separately for men and women. Adjusted means by season, day of the week and age were estimated using weights and covariance analysis. SETTING: Twenty-seven centres in 10 European countries participating in the EPIC project. SUBJECTS: In total, 35 955 subjects (13 031 men and 22 924 women), aged 35-74 years, randomly selected from each EPIC cohort. RESULTS: The centres from southern countries had the highest consumption of V&F, while the lowest intake was seen in The Netherlands and Scandinavia for both genders. These differences were more evident for fruits, particularly citrus. However, slightly different patterns arose for some sub-groups of vegetables, such as root vegetables and cabbage. Adjustment for body mass index, physical activity, smoking habits and education did not substantially modify the mean intakes of vegetables and fruits. CONCLUSIONS: Total vegetable and fruit intake follows a south-north gradient in both genders, whereas for several sub-groups of vegetables a different geographic distribution exists. Differences in mean intake of V&F by centre were not explained by lifestyle factors associated with V&F intake.
