Time trends in the impact factor of Public Health journals
Gonzalo López-Abente, Concha Mu?oz-Tinoco
BMC Public Health , 2005, DOI: 10.1186/1471-2458-5-24
Abstract: We used the IFs of 80 public health journals that were registered by the Science Citation Index from 1992 through 2003 and had been listed for a minimum period of the previous 3 years. Impact factor time trends were assessed using a linear regression model, in which the dependent variable was IF and the independent variable, the year. The slope of the model and its statistical significance were taken as the indicator of annual change.The IF range for the journals covered went from 0.18 to 5.2 in 2003. Although there was no statistical association between annual change and mean IF, most of the fastest growing journals registered mean IFs in excess of 1.5, and some represented emerging areas of public health research. Graphs displaying IF trends are shown.In view of the delay between the publication of IFs and that of any given paper, knowing the trend in IF is essential in order to make a correct choice of journal.Scientific journal impact factor (IF) is directly linked to the probability of a paper being cited. It is currently accepted that a higher IF indicates a better journal quality, existing a correlation among IF and quality indicators at least in some health disciplines [1]. As a result these indices are progressively becoming incorporated into researchers' curricula vitae. In Spain, publication in top-IF journals has occupational implications in terms of academic careers and obtaining research grants [2]. The most widespread and important bibliometric indicators are those referring to the repercussion of scientific activity, and among these, IF has a leading role [3].This pressure means that when it comes to having to select a journal in which to publish their studies, researchers turn to journals with IF, and assess the possibility of publishing in those that have the highest IF possible. Journals having the top IF within each medical specialty tend to be those with the greatest international prestige and highest profile, i.e., the most widely read by resea
Time trend and age-period-cohort effect on kidney cancer mortality in Europe, 1981–2000

BMC Public Health , 2006, DOI: 10.1186/1471-2458-6-119
Abstract: Kidney cancer deaths and population estimates for each country during the period 1981–2000 were drawn from the World Health Organization Mortality Database. Age- and period-adjusted mortality rates, as well as annual percentage changes in age-adjusted mortality rates, were calculated for each country and geographical region. Log-linear Poisson models were also fitted to study the effect of age, death period, and birth cohort on kidney cancer mortality rates within each country.For men, the overall standardized kidney cancer mortality rates in the eastern, western, and northern European countries were 20, 25, and 53% higher than those for the southern European countries, respectively. However, age-adjusted mortality rates showed a significant annual decrease of -0.7% in the north of Europe, a moderate rise of 0.7% in the west, and substantial increases of 1.4% in the south and 2.0% in the east. This trend was similar among women, but with lower mortality rates. Age-period-cohort models showed three different birth-cohort patterns for both men and women: a decrease in mortality trend for those generations born after 1920 in the Nordic countries, a similar but lagged decline for cohorts born after 1930 in western and southern European countries, and a continuous increase throughout all birth cohorts in eastern Europe. Similar but more heterogeneous regional patterns were observed for period effects.Kidney cancer mortality trends in Europe showed a clear north-south pattern, with high rates on a downward trend in the north, intermediate rates on a more marked rising trend in the east than in the west, and low rates on an upward trend in the south. The downward pattern observed for cohorts born after 1920–1930 in northern, western, and southern regions suggests more favourable trends in coming years, in contrast to the eastern countries where birth-cohort pattern remains upward.Kidney cancer incidence and mortality rates have increased during the last years in different

Abstract: the effect of the elevated temperatures experimented in europe during the summer 2003 on mortality was observed in several countries. this study, carried out in spain, describes the mortality between the 1st june and the 31st august and evaluates the effect of the heat wave on mortality. observed deaths were obtained from official vital registers of the capital city of the 50 provinces. deaths from 107 randomly selected rural villages were also obtained from the same source. observed deaths were compared with expected estimated applying a poisson regression model to historical mortality series adjusting for the upwards trend and seasonality observed. meteorological information was provided by the national institute of meteorology. spain experienced three heat waves. total excess deaths associated was 8% (43212 observed compared with 40046 expected). excess deaths were only observed among 65 years old and over (15%). the increased mortality was also observed in rural villages. this phenomenon is becoming an emerging public health problem because of its increasing attributable risk because of the aging of spanish population. alert and response systems based on monitoring of climate related risks, emergency rooms activity and mortality and the strengthening of social and health services response capacity should be considered.
Socio-economic class, rurality and risk of cutaneous melanoma by site and gender in Sweden
Beatriz Pérez-Gómez, Nuria Aragonés, Per Gustavsson, Virginia Lope, Gonzalo López-Abente, Marina Pollán
BMC Public Health , 2008, DOI: 10.1186/1471-2458-8-33
Abstract: A major-sized historical occupational Swedish cohort comprising 2,992,166 workers was used to estimate relative risk of cutaneous melanoma, broken down by gender and anatomical site, for occupational sectors (as a proxy of socio-economic class) and rurality. To this end, Poisson models were fitted for each site in men and women, including occupational sector and town size, with adjustment for age, period of diagnosis and geographical area as possible confounding factors.White collar workers presented a marked increased of risk in men in all melanoma cases, as well as in trunk, upper and lower limbs. This pattern was less clear for women, in which some heterogeneity appeared, as low risks in lower socioeconomic sectors in trunk, or risk excesses in white collar workers in lower limbs did not achieve statistical significance. Males also showed significant differences in risk by rural/urban distribution, but in women this association was limited to CM of lower limb. Risk of CM of head/neck did not vary by occupational sector or town size, thus depicting a specific epidemiological profile, which proved common to both sexes.While differences in risk between men and women could suggest greater homogeneity in UV-exposure behaviour among women, the uniform risk pattern in head and neck melanoma, present in both sexes, might support the coexistence of different aetiological pathways, related to anatomical site.Cutaneous melanoma (CM) is one of the neoplasms more usually associated with higher social class [1-5]. As ultraviolet radiation (UV) is the main aetiological agent for CM, this relationship has been attributed to differences in UV-exposure-related behaviour. The sun is considered responsible for almost 65% of cases [6], mainly through intermittent exposure [7] during summer holidays, something that tends to be more usual among persons having a higher socio-economic class [2] and residing in larger towns [8]. Sun-bed use [9] has also been related to increased CM risk;
Lung cancer mortality in towns near paper, pulp and board industries in Spain: a point source pollution study
Susana Monge-Corella, Javier García-Pérez, Nuria Aragonés, Marina Pollán, Beatriz Pérez-Gómez, Gonzalo López-Abente
BMC Public Health , 2008, DOI: 10.1186/1471-2458-8-288
Abstract: This was an ecological study that modelled the Standardised Mortality Ratio (SMR) for lung cancer in 8073 Spanish towns over the period 1994–2003. Population exposure to industrial pollution was estimated on the basis of distance from town of residence to pollution source. An exploratory, near-versus-far analysis was conducted, using mixed Poisson regression models and an analysis of the effect of municipal proximity within a 50-kilometre radius of each of the 18 installations.Results varied for the different facilities. In two instances there was an increasing mortality gradient with proximity to the installation, though this was exclusively observed among men.The study of cancer mortality in areas surrounding pollutant foci is a useful tool for environmental surveillance, and serves to highlight areas of interest susceptible to being investigated by ad hoc studies. Despite present limitations, recognition is therefore due to the advance represented by publication of the EPER and the study of pollutant foci.Lung cancer is the leading cause of cancer-related death among men in Spain, giving rise to 16,614 deaths in 2005, 27.4% of all male cancer-related deaths. In this same year there were 2,459 deaths among women, accounting for 7% of total female deaths and ranking lung cancer as the third leading cause of cancer-related death after breast and colon cancer [1]. The male:female ratio is 7:1. Owing to its frequency and impact, this tumour is regarded as a serious public health problem. Although the male lung-cancer mortality trend has declined in recent years, in women the trend has been rising, particularly from 1990 onwards, and is currently increasing by 2.4% per annum [2]. Despite diagnostic and therapeutic advances, the disease continues to be highly lethal, with only 12.2% of patients surviving to five years after diagnosis [3].Lung cancer displays marked geographic and temporal variability, which corresponds to the diversity and different distribution of its
Description of industrial pollution in Spain

BMC Public Health , 2007, DOI: 10.1186/1471-2458-7-40
Abstract: All information on industrial pollution discharge in 2001 was drawn from EPER-Spain public records provided by the European Commission server. We described the distribution of the number of industries and amounts discharged for each pollutant, as well as emission by pollutant group and the industrial activities associated with each pollutant. Maps of Spain were drawn up, with UTM coordinates being used to plot pollutant foci, and circles with an area proportional to the emission to depict pollution emission values.The EPER-Spain contained information on 1,437 industrial installations. The industrial plants that discharge pollutant substances into air and water above the pollutant-specific EPER threshold were mainly situated in the Autonomous Regions of Aragon, Andalusia and Catalonia and in Catalonia, the Basque Country and Andalusia respectively. Pollution released in 2001 into air approached 158 million Mt. Emissions into water were over 8 million Mt.A few single industrial plants are responsible for the highest percentage of emissions, thus rendering monitoring of their possible health impact on the surrounding population that much simpler. Among European countries Spain is the leading polluter in almost one third of all EPER-registered pollutant substances released into the air and ranks among the top three leading polluters in two-thirds of all such substances. Information obtained through publication of EPER data means that the possible consequences of reported pollutant foci on the health of neighbouring populations can now be studied.Toxic substances, which are released constantly into the environment (to both air and water) by many types of industrial activities, include a long list of products and pollutants that until now have never been quantified in Spain. Evidence as to the health risk posed by residing in the vicinity of such polluting industries is limited, with cancer and congenital malformations being the most widely studied health problems in the
Municipal mortality due to thyroid cancer in Spain
Virginia Lope, Marina Pollán, Beatriz Pérez-Gómez, Nuria Aragonés, Rebeca Ramis, Diana Gómez-Barroso, Gonzalo López-Abente
BMC Public Health , 2006, DOI: 10.1186/1471-2458-6-302
Abstract: It was possible to compile and ascertain the posterior distribution of relative risk on the basis of a single Bayesian spatial model covering all of Spain's 8077 municipal areas. Maps were plotted depicting standardized mortality ratios, smoothed relative risk (RR) estimates, and the posterior probability that RR > 1.From 1989 to 1998 a total of 2,538 thyroid cancer deaths were registered in 1,041 municipalities. The highest relative risks were mostly situated in the Canary Islands, the province of Lugo, the east of La Coru?a (Corunna) and western areas of Asturias and Orense.The observed mortality pattern coincides with areas in Spain where goiter has been declared endemic. The higher frequency in these same areas of undifferentiated, more aggressive carcinomas could be reflected in the mortality figures. Other unknown genetic or environmental factors could also play a role in the etiology of this tumor.At the European level, Spain ranks midway in terms of thyroid cancer (TC) incidence. This is a tumor that is far more frequent among women than among men. In recent years, incidence rate per 100,000 population has increased from 1.73 to 2.22 in the periods 1993–1996 [1] and 1997–2000 [2] in men, and from 3.63 [1] to 5.69 [2] per 100,000 in women. In the 1990s, mortality due to this tumor in males registered a statistically significant [2] mean annual increase of 1.21%, which in 2004 rose to a rate, standardized to the European population, of 0.33 per 100,000 population [3]. In women, however, TC mortality declined significantly by an average of 0.39% per annum [2], until reaching a rate of 0.49 per 100,000 population in 2004 [3]. Prevalence attributable to cases diagnosed in the preceding 5 years has reached a figure of 1559 cases in men and 4901 in women [4]. In Spain, TC is the tumor with the highest survival rate in women (86% at 5 years), and ranks second after testicular cancer in men (82%) [5].Most thyroid tumors are epithelial and are classified into well-dif

International Journal of Health Geographics , 2011, DOI: 10.1186/1476-072x-10-10
Abstract: This was a hospital-based case-control study covering 626 lung cancer patients and 626 controls recruited in Asturias and matched by ethnicity, hospital, age, and sex. Distances from the respective participants' residential locations to industrial facilities and city centers were computed. Using logistic regression, odds ratios (ORs) and 95% confidence intervals (95%CIs) for categories of distance to urban and industrial pollution sources were calculated, with adjustment for sex, age, hospital area, tobacco consumption, family history of cancer, and occupation.Whereas individuals living near industries displayed an excess risk of lung cancer (OR = 1.49; 95%CI = 0.93-2.39), which attained statistical significance for small cell carcinomas (OR = 2.23; 95%CI = 1.01-4.92), residents in urban areas showed a statistically significant increased risk for adenocarcinoma (OR = 1.92; 95%CI = 1.09-3.38). In the Gijon health area, residents in the urban area registered a statistically significant increased risk of lung cancer (OR = 2.17; 95%CI = 1.25-3.76), whereas in the Aviles health area, no differences in risk were found by area of exposure.This study provides further evidence that air pollution is a moderate risk factor for lung cancer.Lung cancer is the most common cause of cancer-related death. In Spain, it accounted for almost 20,000 deaths in 2007, amounting to 27% of all cancer deaths in males and 7% in females [1]. This cancer displays marked geographic variability, and Asturias, located in Northern Spain, is one of the regions registering clear excess mortality [2], with adjusted mortality rates ranking among the highest in Spain for both sexes [3]. This is a heavily industrialized area, with metal industries, coal mining facilities, and fossil-fuel-fired power plants.While tobacco use is the main risk factor for lung cancer, and available estimates attribute 80% to 90% of cases in men and 55% to 80% of cases in women to cigarette smoking [4], there are other well-kn

Abstract: We analysed 1585 cases (1333 basal cell carcinoma (BCC) and 183 squamous cell carcinoma (SCC)) and 1507 controls drawn from the Helios-I multicenter study. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using logistic regression mixed models.For NMSC as a whole (both histological types), miners and quarrymen, secondary education teachers, and masons registered excess risk, regardless of exposure to solar radiation and skin type (OR 7.04, 95% CI 2.44–20.31; OR 1.75, 95% CI 1.05–2.89 and OR 1.54, 95% CI 1.04–2.27, respectively). Frequency of BCC proved higher among railway engine drivers and firemen (OR 4.55; 95% CI 0.96–21.57), specialised farmers (OR 1.65; 95% CI 1.05–2.59) and salesmen (OR 3.02; 95% CI 1.05–2.86), in addition to miners and quarrymen and secondary education teachers (OR 7.96; 95% CI 2.72–23.23 and OR 1.76; 95% CI 1.05–2.94 respectively). The occupations that registered a higher risk of SCC (though not of BCC) were those involving direct contact with livestock, construction workers not elsewhere classified (OR 2.95, 95% CI 1.12–7.74), stationary engine and related equipment operators not elsewhere classified (OR 5.31, 95% CI 1.13–21.04) and masons (OR 2.55, 95% CI 1.36–4.78).Exposure to hazardous air pollutants, arsenic, ionizing radiations and burns may explain a good part of the associations observed in this study. The Helios study affords an excellent opportunity for further in-depth study of physical and chemical agents and NMSC based on matrices of occupational exposure.Non-melanoma skin cancer is the most frequent tumour among Caucasian populations worldwide. Nevertheless, the study of its frequency poses difficulties. As one of the basic data sources for identification of cases in population cancer registries are hospital and pathology records, the fact that non-melanoma skin cancer is often not grounds for hospital admission may well lead to under-registration of cases. Furthermore, being a disease that can progress with fe

Abstract: Cross-sectional study with personal interview of 1298 women (aged 18 to 60) randomly selected from the electoral rolls of 14 towns in Galicia, a region in the north-west of Spain. HRQL was assessed using the SF-36 questionnaire. The association between body mass index (BMI) and suboptimal scores in the different HRQL dimensions was summarised using odds ratios (ORs), obtained from multivariate logistic regression models. Separate analyses were conducted for women who had finished their education younger than 16 years old and women with secondary education to assess differences in the relationship between BMI and HRQL according to educational level.Among women with primary or lower education, obesity was associated with a higher prevalence of suboptimal values in the following dimensions: Physical functioning (OR: 1.97; 95%CI: 1.22–3.18); Role-physical (OR: 1.81; 95%CI: 1.04–3.14); General health (OR: 1.76; 95%CI: 1.10–2.81); and Role-emotional (OR: 2.52; 95%CI: 1.27–5.03). In women with higher education, physical functioning was the only dimension associated with obesity (OR: 2.02: 95%CI 0.83–4.97).The impact of obesity on women's HRQL is greater among those with a lower educational level. This group registered higher prevalence of obesity and poorer self-perceived health.Obesity is a multifactorial disorder stemming from the interaction between genetic and metabolic factors on the one hand, and nutritional lifestyles and physical activity on the other, both of which are, in turn, conditioned by social, behavioural and cultural factors. It constitutes a major and increasing public health problem worldwide [1]. In some industrialized countries such as USA [2] or Germany [3], the prevalence of obesity exceeds 25% in adults.In Spain, the percentage of self-reported obesity among persons aged 20 years and over has increased in the last decades, rising from 7.7% in 1987 to 15.25% in 2006, in men and women alike [4,5]. Moreover, socio-economic level has been inversely rel
