The purpose of this study was to describe the relative frequency, pattern, and mechanism of surfing injuries. Descriptive data of surfing injuries was collected by using a Web site-based interactive multiple choice survey. Data was collected from May 1998 to August 1999. Completed surveys were obtained from 1,348 individuals reporting 1,237 acute injuries and 477 chronic injuries. Lacerations accounted for 42% of all acute injuries, contusions 13%, sprains/strains 12%, and fractures 8%. Thirty-seven percent of acute injuries were to the lower extremity, and 37% to the head and neck. Fifty-five percent of injuries resulted from contact with ones own board, 12% from another surfer's board, and 17% from the sea floor. Sixty-seven percent of acute surfing injuries are caused by board contact. Older surfers, more expert surfers, and those surfing large waves have a higher relative risk for significant injury. Equipment modifications are suggested that may decrease the risk for injury.
Background We report on the associations between the intake of certain foods and beverages and the incidence of gastric cancer in a cohort of 11 907 randomly selected Japanese residents of Hawaii (6297 women and 5610 men). MethodsThe daily intake of six beverages, cigarettes and alcohol and the weekly frequency of intake of 13 foods and food groups was estimated with a short food frequency questionniare. Over an average follow-up period of 14.8 years, 108 cases of gastric cancer (44 women, 64 men) were identified via linkage to the Hawaii Tumor Registry. ResultsIn gender-combined proportional hazards analyses, the consumption of fresh fruit seven or more times per week was associated with a significantly reduced risk of gastric cancer, compared to lower levels of consumption (relative hazard (RH): 0.6, 95% confidence interval (CI) : 0.4-1.0, P = 0.03). The combined intake of fresh fruit and raw vegetables was inversely associated with the risk of gastric cancer in the total cohort, and among the men (P < 0.05). No significant relationships were found between gastric cancer incidence and the intake of pickled vegetables, miso soup, dried or salted fish, or processed meats among either gender. Compared to non-drinkers, men who drank one cup of coffee per day had a significantly elevated risk of gastric cancer (RH: 2.5, 95% CI: 1.0-6.1, P= 0.05), but there was no evidence of a dose-response relationship. Cigarette smoking and consumption of alcohol were not related to gastric cancer, in analyses restricted to the men. Conclusions The results related to fruit and vegetable intake are consistent with an antinitrosating effect of these foods, while the unexpected association between coffee consumption and gastric cancer is difficult to explain and may represent a chance finding.
The associations between cigarette smoking history and later cognitive performance were examined among 3,429 Japanese-American participants of the Honolulu Heart Program (HHP) and its extension, the Honolulu-Asia Aging Study (HAAS). Cognitive performance was measured by the Cognitive Abilities Screening Instrument (CASI), administered as part of HAAS (mean age at HAAS exam (standard deviation (SD)): 77.7 (4.6) years). Information on smoking history was collected during the first and third HHP exams (mean age (SD) at Exam III: 58.6 (4.7) years). Compared with never-smokers, those who had smoked continuously between Exams I-III and those who had quit smoking during that period had significantly lower CASI scores, after adjustment for age, education, Japanese acculturation, and Exam III alcohol intake. In multiple logistic regression controlling for the above covariates, a significantly higher risk of cognitive impairment (CASI score < 82) was associated with continuous smoking (odds ratio (OR) = 1.36, 95% confidence interval (CI) 1.10-1.69) and quitting between Exams I-III (OR = 1.36, 95% CI 1.03-1.80) compared with never smoking. This excess risk of cognitive impairment among continuous smokers and Exam I-III quitters was slightly diminished by further adjustment for body mass index and several vascular covariates. Additional analyses suggested a reduced risk of cognitive impairment among the longer-term quitters. This study suggests a positive association between smoking during middle age and later risk of cognitive impairment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
