Dairy Products and Prostate Cancer Risk

Differences in the frequency of consumption of 30 selected foods and in the estimated intake of total calories and selected nutrients in relation to alcohol drinking, tobacco smoking, and education were described using information obtained from 1,774 controls of a case‐control study of digestive tract cancers conducted in northern Italy. Heavy alcohol consumption, tobacco smoking, and lower level of education were associated with a diet poorer in several aspects, including lower consumption of fresh fruit and green vegetables and higher intake of specific indicator foods, such as sausages and canned meat. For instance, the mean number of portions of fresh fruit per week was 10.5 among male nondrinkers vs. 9.0 among heavy drinkers, 10.4 among male nonsmokers vs. 8.1 among heavy smokers, and 8.8 in less educated individuals vs. 10.7 among those more educated. Consequently, intake of ß‐carotene, ascorbic acid, and calcium tended to be inversely related to alcohol and tobacco and directly related to education. Most associations were stronger in males, for whom alcohol consumption was also more common in less educated individuals. Calorie intake was directly related to alcohol consumption, largely reflecting calories provided by alcohol itself. However, alcohol drinking was also directly related to fat consumption. In both sexes, there was a strong positive correlation between cigarette smoking and coffee drinking. These results provide quantitative documentation that alcohol drinking, tobacco smoking, and education, three of the major determinants of cancer risks, were also correlates of dietary patterns and, hence, may exert an important confounding or modifying effect on the diet and cancer relationship.     

Tobacco and alcohol consumption: impact on other cardiovascular and cancer risk factors in a southern European Mediterranean population

Tobacco and alcohol consumption are strongly related to other cardiovascular and cancer risk factors. The aim of the present study was to analyse the association of nutrient intake, blood lipid variables and leisure-time physical activity with tobacco and alcohol consumption status. Participants were recruited in a cross-sectional population-based survey, including cardiovascular risk factor measurements and evaluation of physical activity and diet intake in a Mediterranean population (n 1748). Multiple linear regression analysis, adjusted for several confounders, showed a direct association of saturated fatty acids (g and % total energy intake), dietary cholesterol intakes and serum triacylglycerol with smoking. An inverse association was observed for smoking and unsaturated fatty acids (% energy intake), vitamin C, alpha-tocopherol and beta-carotene intakes, leisure-time physical activity and HDL-cholesterol. These associations were not observed for alcohol drinking. After adjusting for the confounders earlier mentioned, low dietary intakes of vitamin C and dietary fibre were more likely in heavy-smokers as compared with non-smokers (odds ratio 1.74 (95 % CI 1.07, 2.73) and 1.94 (95 % CI 1.29, 2.92) of low vitamin C (<60 mg/d) and dietary fibre intakes (<10 g/d) respectively). Alcohol consumption was directly associated with HDL-cholesterol and triacylglycerol, and attenuated the effects of smoking on HDL-cholesterol. These results suggest that the dietary intake of fibre and several antioxidant components of the Mediterranean diet is reduced in smokers, who also show an adverse lipid profile. However, the worst triacylglycerol levels are associated with the combination of heavy smoking and heavy alcohol drinking. Moderate alcohol consumption was not associated with an unhealthy diet pattern or adverse lipid profile. The health benefits of the Mediterranean diet appear to be strongly counteracted by smoking.

Relationship of alcohol consumption to diet: a population-based study in Hawaii

The relationship of alcohol use to diet was examined in 2272 male and 2337 female adults aged 45 y and older who provided a quantitative diet history during 1977-1979. Mean values for each dietary variable, adjusted for smoking, ethnicity, income, and education, were compared in each sex between abstainers and drinkers and by tertile of ethanol intake. Linear relationships with extent of drinking were also sought. Drinkers were found to be less obese than abstainers. Consumption of carbohydrate, vitamins, calcium, fruits, fruit juices, and raw vegetables was greater among abstainers whereas consumption of fat (particularly polyunsaturated fatty acids), cholesterol, zinc, meat, pickled vegetables, and dried fish was greater among drinkers. Because validations of dietary questionnaires have shown that alcohol consumption is more accurately recalled than food intake, the possibility of a residual confounding effect for these dietary variables should be considered in epidemiologic studies of alcohol and health.     

The relationships among socioeconomic status, fruit and vegetable intake, and alcohol consumption

Abstract Purpose . We examined the relationships among fruit and vegetable intake, alcohol consumption, and socioeconomic status (SES). We hypothesized that fruit and vegetable consumption would be inversely associated with alcohol consumption and the relationship would differ by SES. Design . A cross-sectional analysis. Setting . Large, urban Midwestern county. Subjects . A unique, racially/ethnically diverse sample of 9959 adults (response rate: 66.3%). Measures . Fruit and vegetable intake was measured using two items that assessed servings per day. Alcohol consumption was measured in terms of volume of alcohol consumed and binge drinking. Individual measures of SES included education and household income. Analysis . Weighted multivariate linear and Poisson regression were used to estimate effects. Results . The relationship between fruit and vegetable intake and alcohol consumption varied by SES. Those with lower household incomes who consumed five or more servings of fruits and vegetables per day were less likely to engage in binge drinking relative to those consuming zero to one servings of fruits and vegetables per day (risk ratio = .66; 95% confidence interval: .46, .95). No association was observed for higher-household-income individuals. Conclusion . We observed an inverse relationship between fruit and vegetable consumption and alcohol intake in those with lower household incomes but not in those with higher household incomes. Results suggest that the relationship between diet and alcohol consumption may be more relevant in populations with more restricted economic choices. Results are, however, based on cross-sectional data.     

Cumulative Coffee Consumption and Reduced Risk of Oral and Oropharyngeal Cancer

We examined the association between coffee consumption and oral cancer in a hospital-based case-control study comprising 143 patients with oral and oropharyngeal squamous cell carcinoma attended at 3 major hospitals in São Paulo, Brazil, and 240 controls without cancer, recruited from outpatient units of the same hospitals and matched with cases by sex and age. Associations were assessed by multivariate logistic regression conditioned on sociodemographic and behavioral characteristics. Tobacco smoking, alcohol drinking, and higher intake of bacon and deep-fried foods were directly related to disease; the inverse was observed to family income and salad intake. Coffee consumption and tobacco smoking were partially correlated (Spearman correlation coefficient 0.14 among cases, 0.31 among controls). When adjusted for all covariates, a cumulative coffee consumption higher than 18.0 daily liters × year during lifetime was indicated to be protective against disease (adjusted odds ratio 0.39, 95% confidence interval 0.16–0.94, P = 0.037). This observation may have pharmacological implications for clinical medication of these cancers and is relevant to programs aimed at reducing the burden of disease.     

Descriptors of alcohol consumption among noninstitutionalized nonalcoholic elderly

This paper describes relationships between reported alcohol consumption and selected sociodemographic and health variables. Two hundred and four men and 367 women aged 60-95 years were examined as part of a nutritional status survey of elderly. Fifty-three percent of men and 44% of women reported drinking at least 2 g of alcohol per week. Men were more likely to drink than women, and the level of alcohol consumption decreased with age. Drinking was positively associated with education (p less than 0.01) and negatively associated with recent medical care (p less than 0.01), history of MI (p less than 0.05), and denture use (p less than 0.05). Among drinkers, reported alcohol intake was higher for subjects less than age 70 (p less than 0.01), males (p less than 0.01), the college educated (p less than 0.01), and smokers (p less than 0.05). Level of alcohol intake was lower for those who had received medical care in the year preceding study participation (p less than 0.05). Identical results were observed for alcohol intake expressed as percent of total calories. Intake ranged from 3.8% of total calories among subjects 80+ years old to 6.2% of total calories among 60-69-year-olds.     

Predictors of alcohol intake and heavy drinking in early adulthood: a 5-year follow-up of 15-19-year-old Finnish adolescents

Relative contributions of earlier drinking and smoking vs mental health risk factors in predicting alcohol intake and heavy drinking in young adulthood were assessed. Higher average alcohol intake and heavy drinking (13 or more drinks on one occasion) in 1995 were significantly related to male gender and earlier high scores in 1990 of relief smoking, relief drinking, and their interaction. Parental alcohol problems, social group, perceived degree of social support, trait anxiety, number of negative life events, self-esteem, grade-point average, somatic symptoms score, or immature, neurotic, or mature defence style measured in 1990 did not predict alcohol intake or heavy drinking 5 years later. The findings suggest that alcohol intake and heavy drinking in young adulthood can be predicted by earlier self-reports on relief smoking and alcohol intake in adolescence.

Prevalence of risk health behavior among members of private health insurance plans: results from the 2008 national telephone survey Vigitel, Brazil

This article aims at estimating the prevalence of adults engaging in protective and risk health behaviors among members of private health insurance plans. It was used a random sample of individuals over the age of 18 living in the Brazilian state capitals collected on 28,640 telephone interviews in 2008. The results showed that among males there was a high prevalence of the following risk factors: tobacco, overweight, low fruit and vegetable consumption, high meat with fat consumption and alcohol drinking. Among females we found a high prevalence of high blood pressure, diabetes, dyslipidemia and osteoporosis. Men were generally more physically active and women consumed more fruit and vegetables. As more educated males were lower was the prevalence of tobacco, high blood pressure, but also a higher prevalence of overweight, consumption of meat with fat, dyslipidemia and lower number of yearly check-ups done. For females, tobacco smoking, overweight, obesity, decreasing with schooling, and consumption of fruit and vegetables, physical activity, mammography and PAP test, increased with schooling. The health insurance user population constitutes about 26% of Brazilian people and the current study aims to accumulate evidence for health promotion actions by this public.     

Quitting smoking in Northern Italy: A cross-sectional analysis of 2621 subjects

To describe the relationship between sociodemographic factors, life-style habits, selected dietary indicators, smoking-related variables, and quitting smoking we analyzed data derived from the comparison group of a case-control study of colorectal and breast cancers based on a network of teaching and general hospitals in Northern Italy. A total of 2621 subjects (1215 women and 1406 men) who were ever cigarette smokers were included for analysis. Age-adjusted rates of stopping smoking (quit rates) and multivariate odds ratios (OR) of quitting smoking were computed. The overall age-adjusted quit rate was 38.6% for males and 24.9% for females, corresponding to an OR of quitting of 0.6 (95% CI: 0.5–0.7) for females vs males. The quitting rate increased with increasing age. After allowing for age, smoking cessation was more frequently reported by more educated or higher social class individuals. No relationship was present between quitting smoking and alcohol consumption, but quitting smoking was inversely related to coffee consumption. The probability of quitting smoking increased directly with number of cigarettes among males but not among females, who showed a J-shaped pattern. Older, heavy smokers were more likely to give up smoking. A general pattern of increasing rates of quitting smoking with higher consumption of vegetables and fruit, and hence -carotene, was present. This study confirms a positive association between quitting smoking and increasing age, higher education, low coffee consumption, heaviness of smoking and high consumption of vegetables and fruit.     

A prospective study linked both alcohol and tobacco to Dupuytren's disease

OBJECTIVE: To address the role of alcohol intake and tobacco smoking and the combination of the two on subsequent risk of Dupuytren's disease. STUDY DESIGN AND SETTING: Cohort study of 7,254 subjects enrolled in the Copenhagen City Heart Study (1981-1983). Both self-reported information on lifestyle and objective measures at the baseline examination were linked to presence of Dupuytren's disease at a subsequent examination (1991-1994) using multivariate logistic regression analysis. RESULTS: A total of 772 subjects had signs of Dupuytren's disease at follow-up. After adjustment for age, sex, educational level, diabetes, and either alcohol or tobacco consumption, respectively, odds ratios for having the disease increased in a dose-dependent manner with increasing levels of alcohol or tobacco intake; however, there was no statistical interaction between heavy smoking and heavy drinking. CONCLUSION: Alcohol intake and tobacco smoking are independently associated with increased risk of Dupuytren's disease, and the combination of the two conveys a very large risk.     

The relation of diet, cigarette smoking, and alcohol consumption to plasma beta-carotene and alpha-tocopherol levels

The relation of diet and nutritional supplements, cigarette use, alcohol consumption, and blood lipids to plasma levels of beta-carotene and alpha-tocopherol was studied among 330 men and women aged 18-79 years. Dietary carotene, preformed vitamin A, and vitamin E intake were estimated by a self-administered semiquantitative food frequency questionnaire. The correlation of dietary carotene with plasma beta-carotene was reduced in smokers compared with nonsmokers (r = 0.02 vs. 0.44 among men; r = 0.19 vs. 0.45 among women). Smokers had much lower plasma levels of beta-carotene than did nonsmokers (geometric mean 8.5 vs. 15.3 micrograms/dl for men; 17.3 vs. 26.3 micrograms/dl for women) despite only slightly lower intakes of carotenoids. In multiple regression analyses, men who smoked one pack per day had 72% (95% confidence interval (CI) 58-89) of the plasma beta-carotene levels of nonsmokers after accounting for dietary carotene and other variables; for women, the corresponding percentage was 79% (CI 64-99). In similar models, men drinking 20 g of alcohol per day had 76% (CI 65-88) of the beta-carotene levels of nondrinkers; women had 89% (CI 73-108) of the levels of nondrinkers. An interaction term for carotene intake and smoking was statistically significant in a model combining both sexes. These results suggest that plasma levels of beta-carotene among smokers and, perhaps, heavy consumers of alcohol may be reduced substantially below levels due to differences in diet. The correlation of calorie-adjusted intake of vitamin E with lipid-adjusted plasma levels of vitamin alpha-tocopherol was 0.53 for men (n = 137) and 0.51 for women (n = 193) and did not differ by alcohol consumption and cigarette use; these correlations were largely accounted for by use of vitamin supplements. In linear regression models, vitamin E intake and plasma lipids were significant predictors of plasma alpha-tocopherol levels.     

Alcohol drinking and tobacco smoking in gastric cancer. A case-control study

This study compares 210 cases of cancer of the stomach (138 males and 72 females) with 630 controls (414 males and 216 females) afflicted with a wide variety of diseases. All patients (cases and controls) were admitted for treatment at the University Hospital of Montevideo, Uruguay in the time period July 1985-December 1988. They were submitted to the same detailed questionnaire by 3 social workers unaware of the objectives of the study. The analysis was performed at the Louisiana State University of New Orleans, using multiple logistic regression. The variables analyzed were cigarette smoking, alcohol ingestion, salted meat intake, total vegetable consumption, total fruit consumption and "mate" ingestion. Strong positive associations were found in both sexes for low fruit and vegetable consumption, high intake of salted meat and "mate" ingestion. Only males showed significantly elevated OR's for tobacco smoking and alcohol drinking. Of the main tobacco variables, time-dependent one's (age at start, duration) displayed significant gradients of increasing risks. Thus, a prolonged exposure seems more important than the amount smoked per day for the risk of developing gastric carcinoma. Both wine and hard liquor carried increased OR's, but heavy drinkers of wine displayed a six-fold increase in risk, replicating previous reports from France.     

Cumulative coffee consumption and reduced risk of oral and oropharyngeal cancer

We examined the association between coffee consumption and oral cancer in a hospital-based case-control study comprising 143 patients with oral and oropharyngeal squamous cell carcinoma attended at 3 major hospitals in Sao Paulo, Brazil, and 240 controls without cancer, recruited from outpatient units of the same hospitals and matched with cases by sex and age. Associations were assessed by multivariate logistic regression conditioned on sociodemographic and behavioral characteristics. Tobacco smoking, alcohol drinking, and higher intake of bacon and deep-fried foods were directly related to disease; the inverse was observed to family income and salad intake. Coffee consumption and tobacco smoking were partially correlated (Spearman correlation coefficient 0.14 among cases, 0.31 among controls). When adjusted for all covariates, a cumulative coffee consumption higher than 18.0 daily liters × year during lifetime was indicated to be protective against disease (adjusted odds ratio 0.39, 95% confidence interval 0.16-0.94, P = 0.037). This observation may have pharmacological implications for clinical medication of these cancers and is relevant to programs aimed at reducing the burden of disease.     

Dietary intake and lifestyle patterns: correlates with socio-economic, demographic and environmental factors

Four lifestyle dimensions were described based on 20 dietary behaviours as well as information about smoking behaviour, alcohol consumption and physical activity levels, in a sample of about 8000 survey participants from a population-representative sample in Wales in 1990. The first lifestyle dimension, mainly described by frequent intakes of chips, pies and processed meats, Med foods, alcohol drinking and cigarette smoking, was associated with male gender, younger age and lack of University education. The second, mainly described by frequent intakes of green vegetables, fruit, fish, poultry and non-smoking, was associated with older age, social group 1 and University education. The third, mainly described by frequent intake of pasta and rice and a high activity level, was associated with younger age, University education, and being born outside the UK. The final lifestyle dimension was mainly described by frequent intake of cakes, biscuits and sweets, non-smoking, and low alcohol intake, but was only weakly associated with socio-demographic factors. Local area differences in lifestyle patterns were also found. The benefits to health promotion of considering lifestyle as a pattern of inter-related health behaviours, and addressing the underlying determinants of these behaviours at the personal, social and community levels, were reinforced by the findings of this study.     

Factors associated with the improvement of lifestyle among a middle and advanced aged male population]

Factors associated with improvement of lifestyle (diet, smoking, drinking, exercise and health check-up) were studied among 3,503 males aged 40 or more, based on data obtained by two questionnaire surveys which were conducted at about a five year interval in a mountainous area of Aichi Prefecture. Age was positively associated with the improvement of every habit except for health check-up. Developing diseases was associated with the improvement of every habit except for exercise, with strong associations existing between liver diseases and improvement in drinking habits and between diabetes and improved nutritional balance. Improved dietary habits was inversely associated with frequent use of instant foods and irregular eating habits. Moderation in eating was associated with a balanced diet, frequent intake of yellow/green vegetables, fats & oils, and non-smoking at the time of the initial survey. Cessation of smoking was positively associated with fruit intake and inversely associated with irregular meal times, number of cigarettes per day and alcohol intake at baseline. An increase in frequency of exercise was positively associated with consumptions of fruits and dairy products and inversely associated with frequent use of instant foods at time of the initial survey, while an increase in frequency of health check-up was observed among men who had a balanced diet. The improvement of each habit was associated with the improvement of one or more other habits. These results suggest that likelihood for improving lifestyle is higher among men who have a health consciousness and that improvements in these habits are independent.     

Socio-economic, demographic, lifestyle and health characteristics associated with consumption of fatty-sweetened and fatty-salted foods in middle-aged French adults

Few studies have specifically focused on characteristics associated with consumption of combined fatty-salted and fatty-sweetened foods, whereas their identification could be useful for defining effective public health measures. The aim of the present study was to investigate the association between demographic, socio-economic, lifestyle and health characteristics and consumption of these types of food in a general sample of French adults. Dietary intake was assessed using a minimum of six 24?h dietary records collected over a 2-year period in 6240 subjects aged 35-60 years who participated in the Supplémentation en VItamines Minéraux et AntioXydants cohort study. Associations of individual characteristics with high and intermediate consumption of fatty-sweetened and fatty-salted foods were assessed using multivariate polytomic logistic regression models. Risk of moderate or high consumption of fatty-salted foods decreased with increasing age. Current smokers, drinkers, individuals with overweight and with hypertension were more likely to consume moderate or high amounts of such foods. Risk of moderate or high consumption of fatty-sweetened foods decreased with increasing age. Women, individuals living as a couple, moderate drinkers and persons with low or medium physical activity level were more likely to consume moderate or high amounts of such foods. Lower educated subjects, current smokers, heavy drinkers and individuals with severe hypertriacylglycerolaemia were less likely to have moderate or high consumption. Consumption of fatty-sweetened and fatty-salted foods varied according to demographic, lifestyle and health characteristics. Common unhealthy behaviours such as smoking, low physical activity and alcohol drinking, associated with high consumption of these food groups, may help to effectively target public health efforts.     

Dietary and physical activity correlates of long-term weight loss

Covariations in body mass index (BMI), physical activity, macronutrient intake, and the frequency of consumption of specific foods were examined among 82 men and 75 women participating in a behavioral weight loss program over a period of 18 months. Results of repeated measures analyses of covariance showed that BMI change was inversely related to change in physical activity and change in frequency of vegetable consumption. BMI change was positively related to change in calorie intake from fat and change in frequency of consumption of beef, hot dogs, and sweets. Change in fat calories predicted BMI change better than change in total calories. In addition, change in the frequency of consumption of specific foods accounted for a larger percentage of the variance in BMI change than did change in macronutrients (10.4% vs. 5.2%). No differences were found between predictors of weight loss vs. weight maintenance.     

Patterns of fruit, vegetable, and milk consumption among smoking and nonsmoking female teens

BACKGROUND: The increase in teenage smoking, and the fact that concern about body weight is given as a reason for smoking initiation by girls, suggest that food intake may be compromised in female teens who smoke. Daily consumption of a variety of foods is important due to the health-protective constituents they contain. Few studies have documented how smoking and the consumption of fruits, vegetables, and milk may be associated in female teens. METHODS: This study examined the relationship of smoking and the consumption of fruit, fruit juice, vegetables, and milk in ninth- to twelfth-grade Caucasian (n=2797), African-American (n=2196), and Hispanic (n=2052) female teens. Data from the Youth Behavior Risk Survey (1999) were analyzed with SUDAAN software, using logistic regression models. RESULTS: Smoking was significantly associated with decreased odds of consuming milk at 0.74 (95% confidence interval [CI], 0.55-0.98); fruit, 0.70 (95% CI, 0.54-0.92); fruit juice, 0.74 (95% CI, 0.56-0.98); and vegetables, 0.75 (95% CI, 0.63-0.89) among Caucasian female teens, and with decreased odds of consuming fruit juice among Hispanic female teens at 0.59 (95% CI, 0.40-0.89). For each significant food variable, a dose-response relationship was detected with significantly more females consuming each food at lower smoking levels and significantly fewer doing so at the highest level (p<0.05). By contrast, African-American female teen smokers tended to consume higher levels of the specified food/beverages than nonsmokers, but this relationship was not statistically significant. IMPLICATIONS: This study establishes a smoking/food intake interaction for the specific foods tested, in an adolescent female population. Compromising the intake of healthy foods and their protective nutrients leaves young women more vulnerable to the serious health consequences of smoking. These results underscore the need for young women to be educated on the importance of eating maximum servings of fruits and vegetables and dairy products, such as milk, particularly if they smoke or are at risk for smoking initiation. The study also underscores the need to culturally tailor programs according to differences in smoking initiation and eating/dieting behaviors.
