Cross-sectional epidemiological study. To determine the 1-year prevalence of neck pain and low back pain in the Spanish population and their association with sociodemographic and lifestyle habits, self-reported health status and comorbidity with other chronic disorders. No recent population-based epidemiological studies have estimated the prevalence of neck and low back pain in Spain. We analyzed data obtained from adults aged 16 years or older (n = 29,478) who participated in the 2006 Spanish National Health Survey, an ongoing, home-based personal interview which examines a nation-wide representative sample of civilian noninstitutionalized population residing in main family dwellings (household) of Spain. We analyzed prevalence data of neck and low back pain and their relationship with socio-demographic characteristics (sex, age, marital status, educational level, occupational status, or monetary income), self-perceived health status, lifestyle habits (smoking habit, alcohol consumption, sleep habit, physical exercise, or obesity), and the presence of concomitant chronic diseases or symptoms. The 1-year prevalence was 19.5% (95% CI: 18.9-20.1) for neck pain and 19.9% (95% CI: 19.3-20.5) for low back pain. Both neck pain and low back pain were higher among female (26.4% and 24.5%) than male (12.3% and 15.1%). Subjects in the 31 to 50 years group were 1.5 times (95% CI: 1.3-1.8) more likely to report low back pain than participants in the 16 to 30 years group. Individuals reporting neck or low back pain showed worse self-reported health status (OR: 4.9, 95% CI: 4.5-5.3 for neck pain; OR: 4.7, 95% CI: 4.3-5.1 for low back pain) and were more likely to complain of depression (OR: 4.3, 95% CI: 3.9-4.7 or OR: 3.6, 95% CI: 3.3-3.9, respectively). Further, a strong association between neck and low back pain was found (OR: 15.6, 95% CI: 14.2-17.1). Finally, neck pain and low back pain were also associated with several other chronic conditions, particularly arthrosis (OR: 6.5, 95% CI: 6.0-7.0), and headaches (OR: 4.3, 95% CI: 3.9-4.8) for neck pain, and both arthrosis (OR: 5.7, 95% CI: 5.3-6.2), and osteoporosis (OR: 6.3, 95% CI: 5.6-7.2), for low back pain. This Spanish population-based survey showed that neck and low back pain are prevalent and highly associated between them, more frequent in female (particularly neck pain) and associated to worse self-reported health status. Individuals with neck and low back pain were more likely than those without pain to have depression and other painful conditions, including headache and osteoporosis.

Background: COPD is currently the fourth cause of morbidity and mortality in the developed world. Patients with COPD experience a progressive deterioration and disability, which lead to a worsening in their health-related quality of life (HRQoL). The aim of this work is to assess the Health-Related Quality of Life (HRQoL) of patients with stable COPD followed in primary care and to identify possible predictors of disease.Methods: It is a multicenter, epidemiological, observational, descriptive study. Subjects of both sexes, older than 40 years and diagnosed of COPD at least 12 months before starting the study were included. Sociodemographic data, severity of disease, comorbidity, and use of health resources in the previous 12 months were collected. All patients were administered a generic quality-of-life questionnaire, the SF-12, that enables to calculate two scores, the physical (PCS-12) and the mental (MCS-12) component summary scores.Results: 10,711 patients were evaluated (75.6% men, 24.4% women), with a mean age of 67.1 years (SD 9.66). The mean value of FEV₁was 35.9 ± 10.0%. Mean PCS-12 and MCS-12 scores were 36.0 ± 9.9 and 48.3 ± 10.9, respectively. Compared to the reference population, patients with COPD had a reduction of PCS-12, even in mild stages of the disease. The correlation with FEV₁was higher for PCS-12 (r = 0.38) than for MCS-12 (r = 0.12). Predictors for both HRQoL components were sex, FEV₁, use of oxygen therapy, and number of visits to emergency rooms and hospital admissions. Other independent predictors of PCS-12 were age, body mass index and educational level.Conclusion: Patients with stable COPD show a reduction of their HRQoL, even in mild stages of the disease. The factors determining the HRQoL include sex, FEV₁, use of oxygen therapy, and number of visits to emergency rooms and hospital admissions.

The aim of our study was to analyse changes in the incidence, diagnostic procedures, comorbidity, length of hospital stay, costs and in-hospital mortality of patients hospitalised for pulmonary embolism in Spain over a 10-year period.We included all patients who were hospitalised for pulmonary embolism (ICD-9-CM codes 415.11 and 415.19) as the primary diagnosis between 2002 and 2011. Data were collected from the National Hospital Discharge Database, covering the entire Spanish population.115 671 patients were admitted. The overall crude incidence increased from 20.44 per 100 000 inhabitants in 2002 to 32.69 in 2011 (p2, and in 2011 the prevalence increased to 20.8% (p<0.05). Mean length of hospital stay was 12.7 days in 2002 and decreased to 9.99 in 2011 (p<0.05). During the study period, mean cost per patient increased from €3915 to €4372 (p<0.05). In-hospital mortality decreased from 12.9% in 2002 to 8.32% in 2011 (p<0.05). The increase in the use of computed tomographic pulmonary angiography over time was associated with increased incidence and lower mortality.Our results revealed an increase in the incidence of hospitalised pulmonary embolism patients from 2002 to 2011 with concomitant increase in comorbidities and cost. However, length of hospital stay and in-hospital mortality decreased.

The aim of this study was to estimate the prevalence of migraine in the general Spanish population and its association with socio-demographic and lifestyle factors, self-reported health status, and co-morbidity with other conditions. We analyzed data obtained from adults aged 16 years or older (n = 29,478) who participated in the 2006 Spanish National Health Survey (SNHS), an ongoing, home-based personal interview which examines a nation-wide representative sample of civilian non-institutionalized population residing in main family dwellings (household) of Spain. We analyzed socio-demographic characteristics (gender, age, marital status, educational level, occupational status, and monetary monthly income); self-perceived health status; lifestyle habits (smoking habit, alcohol consumption, sleep habit, physical exercise, and obesity); and presence of other concomitant diseases. The 1-year prevalence of diagnosed migraine (n = 3,433) was 11.02% (95% CI 10.55–11.51). The prevalence was significantly higher among female (15.94%) than male (5.91%) and showed the highest value in the 31–50 years age group (12.11%). Migraine was more common in those of lower income (AOR 1.19, 95% CI 1.01–1.41) and who sleep <8 h/day (AOR 1.18, 95% CI 1.04–1.33). Furthermore, worse health status (AOR 2.04, 95% CI 1.76–2.36) and depression (AOR 1.82 95% CI 1.58–2.11) were related to migraine. Finally, subjects with migraine were significantly more likely to have comorbid conditions, particularly chronic (more than 6 month of duration) neck pain (AOR 2.31, 95% CI 1.98–2.68) and asthma (AOR 1.62, 95% 1.27–2.05). The current Spanish population-based survey has shown that migraine is more frequent in female, between 31 and 50 years and associated to a lower income, poor sleeping, worse health status, depression and several comorbid conditions, particularly chronic neck pain and asthma.

Background: Our study aimed at describing the health profiles, life styles and use of health resources by the immigrant population resident in Spain. Methods: Cross-sectional, epidemiological study from the Spanish National Health Survey (NHS) in 2003. We analysed 1506 subjects of both sexes, aged ≥16 years, resident in Spain. Results: The immigrant population present diseases that are similar to those of the autochthonous population. The autochthonous population had significantly higher values for alcohol consumption and smoking (60.8 and 39.6%) than immigrants (39.6 and 27.5%). The percentage of immigrants hospitalized in the preceding 12 months was observed to be higher than that of the Spanish population (11.4 vs. 8.2%, P < 0.05). The immigrant population consumed fewer medical drugs than the Spanish population (42.6 and 49.9%, respectively). Conclusions: Immigrants in Spain display better lifestyle-related parameters, in that they consume less alcohol and smoke less than the autochthonous population. As for the use of health-care resources, while immigrants register higher percentages of hospitalization compared with the Spanish population, there is no evidence of excessive and inappropriate use of other health-care resources.
