Social mobility and healthy behaviours from a gender perspective in the Spanish multicase-control study (MCC-Spain).

There is evidence for the influence of socioeconomic status (SES) on healthy behaviours but the effect of social mobility (SM) is not yet well known. This study aims to analyse the influence of origin and destination SES (O-SES and D-SES) and SM on healthy behaviours and co-occurrence, from an integrated gender and age perspective. Data were obtained from the controls of MCC-Spain between 2008-2013 (3,606 participants). Healthy behaviours considered: healthy diet, moderate alcohol consumption, non-smoking and physical activity. SM was categorized as stable high, upward, stable medium, downward or stable low. Binary and multinomial logistic regression models were adjusted. Those aged <65, with a low O-SES, D-SES and stable low SM are less likely to have healthy behaviours in the case of both women (physically active: OR = 0.65 CI = 0.45-0.94, OR = 0.71 CI = 0.52-0.98, OR = 0.61 CI = 0.41-0.91) and men (non-smokers: OR = 0.44 CI = 0.26-0.76, OR = 0.54 CI = 0.35-0.83, OR = 0.41 CI 0.24-0.72; physically active: OR = 0.57 CI = 0.35-0.92, OR = 0.64 CI = 0.44-0.95, OR = 0.53 CI = 0.23-0.87). However, for those aged ≥65, this probability is higher in women with a low O-SES and D-SES (non-smoker: OR = 8.09 CI = 4.18-15.67, OR = 4.14 CI = 2.28-7.52; moderate alcohol consumption: OR = 3.00 CI = 1.45-6.24, OR = 2.83 CI = 1.49-5.37) and in men with a stable low SM (physically active: OR = 1.52 CI = 1.02-1.26). In the case of men, the same behaviour pattern is observed in those with a low O-SES as those with upward mobility, with a higher probability of co-occurring behaviours (three-to-four behaviours: OR = 2.00 CI = 1.22-3.29; OR = 3.13 CI = 1.31-7.48). The relationship of O-SES, D-SES and SM with healthy behaviours is complex and differs according to age and gender.

Prostate cancer incidence and mortality in Navarre (Spain).

BACKGROUND: Prostate cancer is one of the most commonly diagnosed malignancies among males worldwide. In this study, overall and age-specific incidence and mortality trends are analyzed in order to present the past and current epidemiological situation of the disease in Navarre (Spain). METHODS: Population-based incidence data from the 1975-2010 period, provided by the Cancer Registry of Navarre and prostate cancer specific mortality data for 1975-2013, provided by the Spanish Statistical Office, were used in the analysis. Age-standardized incidence and mortality rates, change-points and annual percentage changes (APC) were estimated by joinpoint regression analysis. One-dimensional P-spline models were used to estimate projections up to 2016. RESULTS: Considerable increases of cancer incidence rates in men aged 45-74 years were observed, with APC of +4.5% (p<0.001), +9.5% (p<0.001) and +2.4% (p<0.05) in the 1975-1990, 1990-2000 and 2000-2010 periods, respectively. In the older than 74 age-group, an increase of incidence rates in the 1975-1999 period was registered (APC +3.3%, p<0.001), followed by a significant decrease up to 2010 (APC -4.0%, p<0.01). Mortality rates rose until 1995 (APC +2.2%, p<0.001) whereas a decline occurred afterwards up to 2013 (APC -3.4%, p<0.001). CONCLUSION: Even though overall prostate cancer incidence rates seem to have stabilized in 2002-2010 in Navarra, trends were different by age groups: increased in men 45-74 years old and decreased in the 75+ year age-group. A decline in mortality rates was observed in both age groups since about 1995. Changes in the use of prostate specific antigen test for screening in oncoming years could affect future prostate cancer trends.

Sex and age differences in the achievement of control targets in patients with type 2 diabetes: results from a population-based study in a South European region.

BACKGROUND: We aimed to determine the degree to which control targets of glycaemia and cardiovascular risk factors were achieved among patients with type 2 diabetes and to investigate sex- and age-related differences in this population. METHODS: This cross-sectional, population-based study was conducted in Spain. Glycated hemoglobin (HbA1c), blood pressure, LDL-c, HDL-c, triglycerides, BMI, and smoking history were obtained from electronic clinical primary care records (n = 32,638 cases). The proportions of patients who met control targets were determined according to sex and age groups. Comparisons between groups were conducted with t-tests for continuous variables, tests for trends in proportions for categorical and ordinal variables, and Pearson's chi-square tests and binary logistic regression models for categorical variables. RESULTS: The overall proportions of patients with type 2 diabetes who met the target objectives for HbA1c (<7 %, 53 mmol/mol), blood pressure (130/80 mmHg), and LDL-cholesterol (100 mg/dl) were 60, 40 and 41 %, respectively. Women were less likely than men to meet the control targets of HbA1c (59 vs 61 %), LDL (35 vs 45 %), and HDL (58 vs 78 %). Patients under 65 years of age presented poorer control than older age groups. Only a minority of patients with type 2 diabetes met the composite target objectives for glycemic control, blood pressure, and LDL. CONCLUSIONS: There are differential gaps in the control results of female patients and younger patients, which should prompt improvements in case management and care. There is room for further improvement in the cardiometabolic control of patients with type 2 diabetes.

Unprocessed red meat and processed meat consumption and risk of stroke in the Spanish cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC).

BACKGROUND/OBJECTIVES: High intakes of unprocessed red or processed meat may increase the risk of stroke. We aimed to examine the association between unprocessed red meat, processed meat and total red meat consumption and risk of total stroke and ischaemic stroke. SUBJECTS/METHODS: Cox proportional hazards regression analyses were conducted based on the data for 41,020 men and women aged 29-69 years at baseline. RESULTS: During a mean follow-up of 13.8 years, 674 incident cases of stroke (531 ischaemic strokes, 79 haemorrhagic strokes, 42 subarachnoid haemorrhages and 22 mixed or unspecified events) were identified. After multiple adjustment, unprocessed red meat, processed meat and total red meat consumption were not correlated with incidence of total stroke or ischaemic stroke in either men or women. The hazard ratios (HRs) for unprocessed red meat and processed meat and risk of total stroke comparing the highest with the lowest quintiles were, respectively, 0.81 (95% confidence interval (CI) 0.54-1.21; P-trend=0.15) and 0.92 (95% CI 0.64-1.32; P-trend=0.82) in men and 1.21 (95% CI 0.79-1.85; P-trend=0.10) and 0.81 (95% CI 0.51-1.27; P-trend=0.17) in women. The HRs for unprocessed red meat and processed meat and risk of ischaemic stroke were, respectively, 0.80 (95% CI 0.51-1.25; P-trend=0.51) and 0.86 (95% CI 0.57-1.29; P-trend=0.77) in men and 1.24 (95% CI 0.74-2.05; P-trend=0.13) and 0.82 (95% CI 0.47-1.42; P-trend=0.31) in women. CONCLUSIONS: In the Spanish European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, unprocessed red meat and processed meat consumption were not associated with risk of stroke in men or women.

Brain and central nervous system cancer incidence in navarre (Spain), 1973-2008 and projections for 2014.

Different studies have pointed out Navarre as one of the regions of Spain with the highest incidence rates of brain and other central nervous system (CNS) cancer. Trend analysis for cancer incidence rates for long periods of time, might help determining risk factors as well as, assessing prevention actions involved in this disease. The objective of this study was to describe the incidence of brain and CNS cancer using data from the population-based cancer registry of Navarre, (Spain) during the period 1973-2008 and provide forecast figures up to-2014. Crude and age-standardized (world population) incidence rates of brain cancer per 100,000 person-years were calculated by the direct method separately by gender, area (Pamplona and others), and age-groups. Penalized splines for smoothing rates in the temporal dimensions were applied in order to estimate and forecast cancer incidence rates. Age-adjusted incidence rates showed an increase over the study and forecast periods in both sexes more marked in women than in men. Higher incidence rates were observed in men compared with women but the differences became smaller with time. The increase was due to the rise of rates in the oldest age groups since the rates for younger age groups remained stable or decreased over time. As the entire aetiology of brain and other CNS cancer is not still clear, keep promoting healthful lifestyles for cancer primary prevention among the whole population is necessary.

Intake of total omega-3 fatty acids, eicosapentaenoic acid and docosahexaenoic acid and risk of coronary heart disease in the Spanish EPIC cohort study.

BACKGROUND AND AIMS: The evidence about the benefits of omega-3 fatty acid intake on coronary heart disease (CHD) is not consistent. We thus aimed to assess the relation between dietary intake of total omega-3 fatty acids (from plant and marine foods) and marine polyunsaturated fatty acids (PUFAs), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), on the risk of CHD in the Spanish cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC). METHODS AND RESULTS: The analysis included 41,091 men and women aged 20-69 years, recruited from 1992 to 1996 and followed-up until December 2004. Omega-3 fatty acid intake was estimated from a validated dietary questionnaire. Only participants with definite incident CHD event were considered as cases. Cox regression models were used to assess the association between the intake of total omega-3 fatty acids, EPA or DHA and CHD. A total of 609 participants (79% men) had a definite CHD event. Mean intakes of total omega-3 fatty acids, EPA and DHA were very similar in the cases and in the cohort, both in men and women. In the multivariate adjusted model, omega-3 fatty acids, EPA and DHA were not related to incident CHD in either men or women. The hazard ratios (HR) for omega-3 were 1.23 in men (95% CI 0.94-15.9, p = 0.20); and 0.77 in women (95% CI 0.46-1.30, p = 0.76). CONCLUSION: In the Spanish EPIC cohort, with a relatively high intake of fish, no association was found between EPA, DHA and total omega-3 fatty acid intake and risk of CHD.

Dietary fibre intake and ischaemic heart disease mortality: the European Prospective Investigation into Cancer and Nutrition-Heart study.

BACKGROUND/OBJECTIVES: Evidence from prospective studies is consistent in showing an inverse association between dietary fibre intake and risk of ischaemic heart disease (IHD), but whether dietary fibre from various food sources differ in their effect on IHD risk is less clear. The objective of this study was to assess the associations of total and food sources of dietary fibre with IHD mortality in the European Prospective Investigation into Cancer and Nutrition-Heart study. SUBJECTS/METHODS: Participants were 306,331 men and women from eight European countries. Dietary fibre intake was assessed using centre or country-specific diet questionnaires and calibrated using a 24-h diet recall. RESULTS: After an average follow-up of 11.5 years, there were 2381 IHD deaths among participants without cardiovascular disease at baseline. The calibrated intake of dietary fibre was inversely related with IHD mortality; each 10 g/day was associated with a 15% lower risk (relative risk (RR) 0.85; 95% confidence interval (CI): 0.73-0.99, P=0.031). There was no difference in the associations of the individual food sources of dietary fibre with the risk of IHD mortality; RR for each 5 g/day higher cereal fibre intake was 0.91 (CI: 0.82-1.01), RR for each 2.5 g/day fruit fibre intake was 0.94 (CI: 0.88-1.01) and RR for each 2.5 g/day vegetable fibre intake was 0.90 (95% CI: 0.76-1.07). CONCLUSION: A higher consumption of dietary fibre is associated with a lower risk of fatal IHD with no clear difference in the association with IHD for fibre from cereals, fruits or vegetables.

[Incidence rate trends for colorectal cancer in Navarre (North of Spain) in the 1990-2005 period]. / Tendencias en las tasas de incidencia de cáncer colorrectal en Navarra en el periodo 1990-2005.

BACKGROUND: In Spain, an increase in the incidence of colorectal cancer (CRC) has been observed in both sexes in recent years, probably due to an improved diagnostic, the westernization of dietary habits, and worse obesity levels, among others factors. In this work, the CRC incidence rate trends in different health areas in Navarre (northern Spain) are studied during the 1990-2005 period. METHODS: An estimated incidence trend curve for each health area and the corresponding confidence bands were obtained for each gender using P-spline models. RESULTS: These results show an increasing trend of CRC in most of the areas in both sexes, being less pronounced in women than in men. In the central area of Pamplona (the capital) a decreasing trend has been observed for men during the period studied. CONCLUSIONS: Primary prevention is the best strategy to change the increasing trend observed in most areas of the province of Navarre. However, a healthy lifestyle has long-term results, so it is important to have an early detection program that would serve as a short-term prevention strategy.

Alcohol intake and the risk of coronary heart disease in the Spanish EPIC cohort study.

BACKGROUND: The association between alcohol consumption and coronary heart disease (CHD) has been widely studied. Most of these studies have concluded that moderate alcohol intake reduces the risk of CHD. There are numerous discussions regarding whether this association is causal or biased. The objective of this paper is to analyse the association between alcohol intake and CHD risk in the Spanish cohort of the European Prospective Investigation into Cancer (EPIC). METHODS: Participants from the EPIC Spanish cohort were included (15 630 men and 25 808 women). The median follow-up period was 10 years. Ethanol intake was calculated using a validated dietary history questionnaire. Participants with a definite CHD event were considered cases. A Cox regression model adjusted for relevant co-variables and stratified by age was produced. Separate models were carried out for men and women. RESULTS: The crude CHD incidence rate was 300.6/100 000 person-years for men and 47.9/100 000 person-years for women. Moderate, high and very high consumption was associated with a reduced risk of CHD in men: hazard ratio 0.90 (95% CI 0.56 to 1.44) for former drinkers, 0.65 (95% CI 0.41 to 1.04) for low, 0.49 (95% CI 0.32 to 0.76) for moderate, 0.46 (95% CI 0.30 to 0.71) for high and 0.50 (95% CI 0.29 to 0.85) for very high consumers. A negative association was found in women, with p values above 0.05 in all categories. CONCLUSIONS: Alcohol intake in men aged 29-69 years was associated with a more than 30% lower CHD incidence. This study is based on a large prospective cohort study and is free of the abstainer error.

[Incidence and mortality due to cancer in Navarre, 1998-2002. Trends in the last 30 years]. / Incidencia y mortalidad por cáncer en Navarra, 1998-2002. Evolución en los últimos 30 años.

Between 1998-2002, 16,952 new cases of cancer were registered in Navarre. In men, the most frequently diagnosed cancers were in the following order: prostate, lung, colon and rectum, bladder and stomach, which accounted for 63.2%. In women, the sites were breast, colon and rectum, corpus uteri, stomach and ovary, which accounted for 57.6% of the cases. In the same period, 1998-2002, 4,127 men and 2,470 women died from cancer. Sixty percent of all deaths due to malign tumours in men were due to cancer of the lung, prostate, colon and rectum, stomach and bladder. In women this was due to cancers of colon and rectum, breast, stomach, pancreas and lung, which accounted for 49% of the cases. In men in Navarre there has been an increase in the incidence rates of cancer of the prostate, kidney and non-Hodgkin lymphoma. Avoidable cancers such as those related to smoking (lung, oral cavity and pharynx or pancreas) continue to rise, and represent a greater global risk of dying from cancer in the latest period studied than in the decades of the 1970s and 1980s. From 1995 up to the present, mortality due to cancer has moved from occupying the second place to become the first cause of death among men in Navarre. The global risk of death due to cancer in men is now equal to the first period studied, 1975-1977. Amongst women the global risk of death due to cancer fell by 25% between 1975 and 2002, basically at the cost of breast and stomach cancer. Tumours related to smoking increased both in mortality and in incidence and appear as a significant health problem amongst women in Navarre. Breast cancer has increased in incidence, with lower mortality figures than those of the first period 1975-1977. Invasive cancer of the cervix remains at very low rates in comparison with many European countries, including Spain. In both sexes colorectal and skin cancer has increased, while the incidence and mortality of stomach cancer continues to fall.

Changes in breast cancer mortality in Navarre (Spain) after introduction of a screening programme.

OBJECTIVE: The aim of this study was to assess changes in the trend of breast cancer mortality in Navarre, and the effect that a screening programme may have had on these changes. METHODS: A breast cancer screening programme targeting women aged 45-65 years was launched in Navarre in September 1990. Breast cancer deaths between 1975 and 2004 were identified from the Navarre Mortality Registry, and the date of diagnosis was obtained by linkage with the population-based Navarre Cancer Registry. We compared breast cancer mortality during the pre-screening (1987-89) and screening (2002-04) periods, and with the estimated rate in the last period calculated by a linear model with a Poisson distribution. The long-term trends (from 1975 through 2004) were described by joinpoint regression analysis. Prevalent cases (those diagnosed before 1991) were excluded to minimize dilution of the benefit in the post-screening period due to deaths from tumours diagnosed before screening began. RESULTS: The joinpoint analysis showed a rising trend in breast cancer mortality rates until 1994, followed by a continual decrease of just over 5% per year. A comparison of mortality rates between the last pre-screening and the screening periods showed a decrease of 36% (95% confidence interval [CI] 21-48%), with the largest reduction in the 50-69 years age group (52%; CI: 33-65%). In this age group, mortality in the 2002-04 period was 62% lower than that projected from extrapolation of the pre-screening trend, while in unscreened age groups (30-44 and > or =75 years), mortality was only 22% lower. When prevalent tumours were excluded, the 50-69 years age group presented a further decrease in mortality than when all tumours were considered. CONCLUSIONS: Fourteen years after the introduction of a screening programme, a major reduction in breast cancer mortality has been observed.

[Recent trends of the main causes of death in Navarre. 1995-2004]. / Tendencias recientes de las principales causas de muerte en Navarra. 1995-2004.

UNLABELLED: We present the statistics for mortality in Navarre for the 1995-2004 period by sex, age and cause of death. METHODS: The data proceeds from the statistical bulletins on death. The 1995-1999 period is compared with the 2000-2004 period, using adjusted rates to the population of Navarre for the year 2001 and the rate of potential years of life lost between 0-70 years adjusted to the European population. RESULTS: Life expectancy at birth in the 2000-2004 period was 77.9 years in men and 85 years in women, the latter being one of the highest registered at the world level. Infant mortality fell to 3.3 per 1,000 living newborn infants. The risk of death has fallen in practically all age groups, with a notable fall in mortality of 40% in the 25-34 group at the cost of AIDS. There has been a significant increase of mortality due to lung cancer amongst women under 65 years of age (46%) in the 2000-2004 period with respect to the previous five year period and a sharp fall in mortality due to breast cancer (45.4%). In both sexes there has been a continued fall of mortality due to cerebrovascular diseases, ischaemic heart diseases, cardiac failure and arteriosclerosis and of mortality due to ulcer and cirrhosis. The rates of mortality in Navarre in all the main groups of causes are lower than those of Europe, except for the rate of mortality due to external causes. CONCLUSIONS: The increase of mortality due to lung cancer and other cancers related to smoking, due to the spread of consumption in recent decades, could have a negative influence on the life expectancy of women in Navarre in coming years. The prevention of mortality due to external causes and the prevention of deaths linked to tobacco consumption are the two priorities that emerge from the data on mortality in this autonomous community.

[Study of mortality in a urban basic health area]. / Estudio de la mortalidad en una zona básica de salud urbana.

OBJECTIVE: To find the pattern of causes of mortality in the Chantrea (Navarra) Health District and the trends in main causes of death between 1987 and 1995. DESIGN: Descriptive study. SETTING: Urban primary care centre. STUDY POPULATION: Population belonging to the Chantrea Health District.Interventions. 1986 data from the Municipal Roll of inhabitants of Chantrea were crossed with the Navarra mortality figures to find the deaths occurred between 1986 and 1995. Overall mortality and mortality for the main reasons were analysed for both sexes and for the periods 1987-1990 and 1991-1995. RESULTS: Between 1991 and 1995, Chantrea had a mortality rate close to that of the European population: 711 per 100000 inhabitants for men and 403 per 100000 for women. The main causes of death were circulatory diseases, tumours, respiratory diseases and external causes. Overall mortality rates dropped by 11.8% among men and by 8% among women from the 1987-1990 period to the 1991-1995 period. Statistically significant drops in mortality were noted for circulatory diseases and for malignant oesophageal tumours in men. AIDS as cause of death increased significantly among men. CONCLUSIONS: Low rates of overall mortality in men and women of Chantrea and, in particular, mortality rates for circulatory disease were below the figures recorded in most European countries. Other causes of death, such as traffic accidents, AIDS or malignant tobacco-related tumours had moderately high rates.

[Nosocomial and community outbreak of epidemic keratoconjunctivitis in Navarra in 1996]. / Brote nosocomial y communitario de queratoconjuntivitis epidémica en Navarra en el año 1996.

BACKGROUND: Epidemic keratoconjunctivitis is an acute, generally bilateral infection, that appears sporadically or in outbreaks from a source of common infection which may be a visit to the ophthalmologist or a swimming pool. Keratitis may evolve to form sub-epithelial injuries in the cornea lasting as much as several months. METHODS: Description of an outbreak of epidemic keratoconjunctivitis that took place in Navarra (Spain) between April and August 1996 and which affected at least 266 people. RESULTS: The epidemiological research highlights the existence of two ophthalmologist consulting rooms as the transmission mechanism for the infection in 46 of the 116 patients researched. The spread of the infection in the environment of the patients was recorded in 119 cases, 62 of which are considered secondary cases. The aetiological diagnosis of the outbreak was carried out 11 days after the start of the microbiological research, isolating adenovirus in conjunctival samples of 8 of the 19 patients researched. CONCLUSIONS: The preventive measures taken to control the outbreak and their effectiveness was highlighted by the gradual reduction in cases.

[Approximation to the prevalence of heroin users in Navarre in 1990]. / Aproximación a la prevalencia de usuarios de heroína en Navarra en 1990.

Intensive multi-agency case finding is a methodology developed to make an estimation of the number and sociodemographic characteristics of known heroin users in a given community. It basically consists of collecting information from services and/or sanitary, social and penal institutions which in the course of their activities contact, or are contacted by persons who are described as heroin users. With the aim of estimating the magnitude of heroin use in Navarra, information about heroin users was requested from public treatment centers for drug-dependences, therapeutic communities, psychiatric emergencies, general hospitals, hepatitis case registry, HIV+ case registry, prisons, forensic and various social services. The study covered the whole Autonomous Community (512,512 residents) during the year of 1990. Overall 1231 persons were counted as heroin users representing a prevalence rate of 2.4 cases/1000 residents. They were mainly male (3 to 1), and a 72% of cases were aged between 20 and 29. The demographic distribution was mainly urban (3.4 to 1) and there were large differences among the different urban zones.

[Inequality before death: a comparative study between Navarra communities in the population segment from 25 to 74 years old]. / Desigualdad ante la muerte: estudio comparativo entre comunidades de Navarra en el segmento de población de 25 a 74 años.

OBJECTIVE: To identify differences in mortality between communities in function of certain socio-economic factors. Firstly, between the urban and rural population of Navarra; and secondly, among different neighbourhoods in Pamplona categorised according to their socioeconomic status. DESIGN: Descriptive study. As the instrument of comparison, the standard mortality rates (SMR) have been used with the direct method. The relationship between mortality and socio-economic status in the neighbourhoods of Pamplona has been analysed by means of lineal regression. SITE. Institute of Public Health of Navarra. PATIENTS OR OTHERS PARTICIPANTS: Those people recorded on the Municipal Censuses of Navarra in 1986, who were between 25 and 74 years old. 8,086 of these died during our period of study, which covered the five years between 1985 and 1989. MAIN MEASUREMENTS AND RESULTS: The SMRs for all causes in men (741 x 10(6)) and women (324 x 10(6)) who live in rural communities are significantly lower (p less than 0.05) than those in urban communities (863 and 390). The specific cause of death which marks the most difference between the two types of community are tumours (p less than 0.05). In the capital (Pamplona), masculine mortality was found to increase in line with the socio-economic status of the neighbourhood lived in (p = 0.017). CONCLUSIONS: There is greater mortality in urban than in rural communities; and in neighbourhoods with low socio-economic status as against those with a high status. However, in this second case, the greater mortality only applies to men.
