Non-occupational risk factors for adult soft-tissue sarcoma in northern Italy

The role of socioeconomic and anthropometric indicators, tobacco, alcohol consumption, dietary habits, and medical history in the etiology of soft-tissue sarcoma (STS) was examined in a hospital-based case-control study, conducted in the Friuli-Venezia Giulia region of northeast Italy, between 1985 and 1990. A total of 88 STS cases (53 males and 35 females; median age: 52 years) and of 610 controls (306 males and 304 females; median age: 54 years) were interviewed. There were significant excess risks associated with a history of herpes zoster infection (odds ratio [OR]=2.4,95 percent confidence interval [CI]=1.1–5.3), chicken pox (OR=2.2, CI=1.2–4.3) and mumps in childhood (OR=2.0, CI=1.1–3.9). History of diabetes was also linked to a nonsignificant increase in STS risk (OR=1.8, CI=0.6–5.4), whereas exposure to radiation for diagnostic or therapeutic purposes was not related to the probability of developing STS. None of the investigated socioeconomic and anthropometric indicators seemed to affect STS risk; neither did tobacco smoking, nor consumption of alcohol, coffee, and tea beverages. Conversely, among the dietary habits investigated, a significant positive association emerged with an increasing frequency of consumption of dairy products (% MathType!MTEF!2!1!+-% feaafeart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn% hiov2DGi1BTfMBaeXafv3ySLgzGmvETj2BSbqefm0B1jxALjhiov2D% aebbfv3ySLgzGueE0jxyaibaiiYdd9qrFfea0dXdf9vqai-hEir8Ve% ea0de9qq-hbrpepeea0db9q8as0-LqLs-Jirpepeea0-as0Fb9pgea% 0lrP0xe9Fve9Fve9qapdbaqaaeGacaGaaiaabeqaamaabaabcaGcba% Gaae4XdmaaCaaaleqabaGaaGOmaaaaaaa!3DA2!\[{\rm{\chi }}^2\]for trend=6.8, P<0.01) and oil (% MathType!MTEF!2!1!+-% feaafeart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn% hiov2DGi1BTfMBaeXafv3ySLgzGmvETj2BSbqefm0B1jxALjhiov2D% aebbfv3ySLgzGueE0jxyaibaiiYdd9qrFfea0dXdf9vqai-hEir8Ve% ea0de9qq-hbrpepeea0db9q8as0-LqLs-Jirpepeea0-as0Fb9pgea% 0lrP0xe9Fve9Fve9qapdbaqaaeGacaGaaiaabeqaamaabaabcaGcba% Gaae4XdmaaCaaaleqabaGaaGOmaaaaaaa!3DA2!\[{\rm{\chi }}^2\]for trend=4.3, P<0.05), while a negative association was seen for intake of whole grain bread and pasta (OR for highest cf lowest tertile=0.4, CI=0.2–0.9).Support for this project was contributed by the Italian Association for Cancer Research, Milan, and the Italian National Research Council (CNR Applied Project Oncology, Contract 87.01544.44).

Influence of Hypertension, Lipometabolism Disorders, Obesity and Other Lifestyles on Spontaneous Intracerebral Hemorrhage

Objective To investigate whether hypertension, abnormal lipometabolism, obesity, cigarette smoking and alcohol drinking affect the intracerebral hemorrhagic volumes (IHV) in patients with spontaneous intracerebral hemorrhage (SIHP), and to explore the roles of these factors in spontaneous intracerebral hemorrhage (SIH). Methods Five hundred patients with acute SIH and 200 healthy adult volunteers (HAV) were enrolled in a study of independently randomized controlled design, in which the levels of systolic pressure (SP) and diastolic pressure (DP), and total cholesterol (TCH), triacylglycerols (triglycerides, TG), high density lipoprotein cholesterol (HDL-CH), low density lipoprotein cholesterol (LDL-CH) in serum as well as the level of erythrocytic membrane cholesterol (EM-CH) were measured, and the body mass index (BMI), daily cigarette smoking consumption (DCSC) and daily pure alcohol consumption (DPAC) were calculated. Results Compared with the average parameters in the HAV group, those of SP, DP, TG,     

Tobacco, alcohol use, and risks of laryngeal and lung cancer by subsite and histologic type in Turkey

Effects of tobacco smoking and alcohol use on risks of cancers of thelarynx and lung have been evaluated extensively in industrialized countries.Few studies on the effect of these risk factors have been reported fromdeveloping countries. We conducted a case-control study to evaluate risks oflaryngeal and lung cancers in men by subsite and cell type in relation tosmoking and alcohol drinking in Turkey, a country where smoking and alcoholconsumption patterns are different from those in industrialized countries. Weidentified 832 laryngeal and 1,210 lung cancer cases and 829 controls withinformation on smoking and alcohol use (amount and duration) and histologiccell type from an oncology treatment center of a Social Security Agencyhospital in Istanbul, Turkey, admitted between 1979 and 1984. Both laryngealand lung cancer showed significant associations with smoking and alcoholdrinking, but no monotonic dose-response was obtained for alcohol drinking.Among smokers, the highest risks were observed in the supraglottis region ofthe larynx (odds ratio [OR] = 4.1) after adjustment for age and alcohol use.Among alcohol drinkers, the highest risks were observed in the glottis regionof the larynx (OR = 1.7) after adjustment for age and smoking. In theanalysis by the cell type of lung cancer among ever-smokers, small cell typeshowed the highest risk (OR = 5.4), while it showed no association withalcohol drinking. Cumulative cigarette use (pack-years) and number ofcigarettes per day showed stronger associations than years smoked for bothcancer sites. The relative risks of joint exposure to smoking and alcoholwere 12.2 for laryngeal cancer and 14.1 for lung cancer among heavy smokersand heavy alcohol drinkers. This study provides epidemiologic evidence fromTurkey that smoking and alcohol use are associated with risks of cancers ofthe larynx and lung.     

Frequency and Correlates of Substance Use among Preadolescents and Adolescents in a Swiss Epidemiological Study

Alcohol use and nicotine use were investigated in a representative sample of 1110 study participants aged 10 to 17 years. In addition to questions on substance use, the participants responded to questionnaires covering behavior and emotions, life events, self-related cognitions, coping capacities, perceived parental behavior, perceived school environment, and the social network. The gender gap in substance use tended to close with increasing age. Parental substance use served as a model for substance use in the participants. Substance users had more abnormal scores on almost all variables as compared to abstaining controls. Lack of acceptance and control, pressure to achieve at school, and life events significantly predicted substance use. The latter served as a moderating risk variable for delinquent behavior under stress.     

Risk Factors for Male Breast Cancer (United States)

Objectives: The etiology of male breast cancer is obscure, although an excess risk has been associated with Klinefelter syndrome, testicular disorders, benign breast disease including gynecomastia, use of exogenous estrogens, radiation, and a family history of male or female breast cancer. We conducted a case-control study to investigate risk factors further for breast cancer in men.Methods: Based on data from the 1986 National (United States) Mortality Followback Survey (NMFS) of almost 20,000 deceased adults (age 25 years or over), we compared information obtained from next-of-kin interviews of 178 men who died of breast cancer with that of 512 male controls who died of other causes. Information was obtained on selected demographic and other factors, including diet, exercise, occupation, height and weight, and use of tobacco and alcohol.Results: Increased risks were found for men who were described by their next-of-kin as very overweight (odds ratio [OR] = 2.3, 95 percent confidence interval [CI] = 1.1-5.0). The risks associated with the three upper quartiles of body mass index (BMI) (wt/ht²) were 1.3, 1.6, and 2.3, respectively, with a significant dose-response relationship (P < 0.01). An excess risk was also associated with limited exercise (OR = 1.3, CI = 0.8-2.0). Consumption of red meat was associated with an increased risk, and consumption of fruits and vegetables with a decreased risk, although the trends were not significant. No association was found for tobacco or alcohol use, but an excess risk was associated with higher levels of socioeconomic status (SES) (OR = 1.8, CI = 1.1-3.0).Conclusions: Our study suggests that obesity increases the risk of male breast cancer, possibly through hormonal mechanisms, while dietary factors, physical activity, and SES indicators also deserve further investigation.
