As the cost of air travel has decreased substantially in the USA and Europe over the past few decades, leisure travel to vacation destinations during the winter months has expanded significantly. This trend has probably increased the incidence of significant ultraviolet radiation exposure and sunburn in a broader population who could not previously afford this kind of travel. The purpose of this study was to analyse the correlation between increasing accessibility to air travel and melanoma incidence. This ecological study surveyed air travel patterns and melanoma incidence over the past three decades. Melanoma age-adjusted incidence was obtained from the United States Surveillance, Epidemiology, and End Results 9 Registry Database, 1975-2000, and the Cancer Registry of Norway, 1965-2000. United States mean inflation-adjusted airfare prices for four airports linked to leisure destinations (Miami, Los Angeles, San Diego, Phoenix) were compared with melanoma incidence. Parallel analyses were performed using annual domestic passenger-kilometres and melanoma incidence in Norway. Declining United States leisure-specific airfares corresponded strongly with increasing melanoma incidence (r = 0.96, r = 0.92, P
To discover whether the number of fatal alcohol peaks during festivities characterized by unrestrained drinking and relates to sales of alcoholic beverages.
Time-series and cross-sectional.
Fatal alcohol poisonings and retail alcohol sales in Finland in 1983-99.
Fatal alcohol poisonings were found to peak during weekends and in the May Day, Midsummer Day and Christmas celebrations. Regression analysis of quarterly series lead to a model showing that 1% increase in the sales of spirits increases the number of fatal alcohol poisonings by 0.4%.
At the population level, increases in the sales of spirits and periods of hard drinking seem to increase deaths from alcohol poisoning. The findings could be of use in efforts to decrease hard drinking.
Alcohol consumption is known to increase during Christmas time and excessive alcohol consumption has been proven to be associated with gastrointestinal bleeding and certain vitamin deficiencies. While food fortification is well known and practiced in most countries, food or beverages fortified with medicine has never been practiced on a wider scale, just as alcohol rarely is fortified. In this article it is speculated how alcohol fortified with proton pump inhibitor and vitamin B would effect alcohol-related morbidity.
Attendance at summer outdoor mass gatherings may lead to heat- and sun-related illness. The purposes of this study were: (1) to estimate the proportion of people in attendance at the 2003 Canada Day celebration in the National Capital Region who used sun and heat protective items; (2) to identify factors associated with the utilization of these protective items; and (3) to provide research data to public outdoor event organizers when developing evidence-based plans for safer events. A naturalistic observational cross-sectional method was used to gather information at the 2003 Canada Day celebration in the National Capital Region on attendees' demographics, the sun and heat protective items they used and the protective resources available at the event sites. Of the 398 observed attendees, the proportion using any one of the protective items ranged from 3 percent (an open umbrella) to 51.5 percent (sunglasses). Females were more likely to use protective items more than males, and adults more likely than children. Planners of public outdoor events should consider the factors that influence the utilization of sun and heat protective behaviours and the environmental modifications that would allow participants to make safe choices.
The aim of this study was to investigate admittance rates and doctors workload during Christmas. In addition, we examined if admittance data supports the common notions that overeating during Christmas results in increased rate of admittances for abdominal problems and that there is an increase in admittance of the elderly at the end of Christmas (i.e. "granny dumping").
A retrospective study analyzing data from the database of the hospital units of Sydvestjysk Sygehus was performed. Data covered admittance in the months spanning from November through January in 1994-2010. Data from Christmas was compared with data from adjacent months.
During Christmas more patients with abdominal complaints were admitted to the hospital (p
Alcohol is a major risk factor for liver cirrhosis. Recently, it was proposed that colder climate might causally lead to increased consumption of alcohol.
We performed an ecologic study, using monthly updated data on mean temperature, sunlight hours and alcohol consumption from ten regions in Sweden, using publicly available data. A generalised additive model, adjusted for region, was applied to examine the association between mean temperature and mean sunlight hours with mean alcohol consumption.
We found a non-linear inverse association between mean monthly temperature and mean alcohol consumption, suggesting that warmer temperature was associated with increased alcohol consumption and colder temperature with a decreased consumption. We found no association between mean sunlight hours and alcohol consumption. Consumption was highest during public holidays.
We found no association between a colder climate and increased alcohol consumption. Socio-economic factors are likely to explain the suggested association.
