Background: Active commuting to school has declined over time, and interventions are needed to reverse this trend. The main objective was to investigate the effects of a school-based intervention on active commuting to school and health-related fitness in school-age children of Southern Spain.Methods: A total of 494 children aged 8 to 11 years were invited to participate in the study. The schools were non-randomly allocated (i.e., school level allocation) into the experimental group (EG) or the control group (CG). The EG received an intervention program for 6 months (a monthly activity) focused on increasing the level of active commuting to school and mainly targeting children's perceptions and attitudes. Active commuting to school and health-related fitness (i.e., cardiorespiratory fitness, muscular fitness and speed-agility), were measured at baseline and at the end of the intervention. Children with valid data on commuting to school at baseline and follow-up, sex, age and distance from home to school were included in the final analysis (n = 251). Data was analyzed through a factorial ANOVA and the Bonferroni post-hoc test.Results: At follow up, the EG had higher rates of cycling to school than CG for boys only (p = 0.04), but not for walking to school for boys or girls. The EG avoided increases in the rates of passive commuting at follow up, which increased in the CG among girls for car (MD = 1.77; SE = 0.714; p = 0.010) and bus (MD = 1.77; SE = 0.714; p = 0.010) modes. Moreover, we observed significant interactions and main effects between independent variables (study group, sex and assessment time point) on health-related fitness (p < 0.05) over the 6-month period between groups, with higher values in the control group (mainly in boys).Conclusion: A school-based intervention focused on increasing active commuting to school was associated with increases in rates of cycling to school among boys, but not for walking to school or health-related fitness. However, the school-based intervention avoided increases in rates of passive commuting in the experimental group, which were significantly increased in girls of the control group.

Background: Our aim is to conduct an exploratory study to provide an in-depth characterization of a neighborhood's social and physical environment in relation to cardiovascular health. A mixed-methods approach was used to better understand the food, alcohol, tobacco and physical activity domains of the urban environment.Methods: We conducted this study in an area of 16,000 residents in Madrid (Spain). We obtained cardiovascular health and risk factors data from all residents aged 45 and above using Electronic Health Records from the Madrid Primary Health Care System. We used several quantitative audit tools to assess: the type and location of food outlets and healthy food availability; tobacco and alcohol points of sale; walkability of all streets and use of parks and public spaces. We also conducted 11 qualitative interviews with key informants to help understanding the relationships between urban environment and cardiovascular behaviors. We integrated quantitative and qualitative data following a mixed-methods merging approach.Results: Electronic Health Records of the entire population of the area showed similar prevalence of risk factors compared to the rest of Madrid/Spain (prevalence of diabetes: 12 %, hypertension: 34 %, dyslipidemia: 32 %, smoking: 10 %, obesity: 20 %). The food environment was very dense, with many small stores (n = 44) and a large food market with 112 stalls. Residents highlighted the importance of these small stores for buying healthy foods. Alcohol and tobacco environments were also very dense (n = 91 and 64, respectively), dominated by bars and restaurants (n = 53) that also acted as food services. Neighbors emphasized the importance of drinking as a socialization mechanism. Public open spaces were mostly used by seniors that remarked the importance of accessibility to these spaces and the availability of destinations to walk to.Conclusion: This experience allowed testing and refining measurement tools, drawn from epidemiology, geography, sociology and anthropology, to better understand the urban environment in relation to cardiovascular health.

Background: The importance of a healthy diet in relation to cardiovascular health promotion is widely recognized. Identifying specific dietary patterns related to early atherosclerosis would contribute greatly to inform effective primary prevention strategies.Objectives: This study sought to quantify the association between specific dietary patterns and presence and extent of subclinical atherosclerosis in a population of asymptomatic middle-aged adults.Methods: The PESA (Progression of Early Subclinical Atherosclerosis) study enrolled 4,082 asymptomatic participants 40 to 54 years of age (mean age 45.8 years; 63% male) to evaluate the presence of subclinical atherosclerosis in multiple vascular territories. A fundamental objective of this cohort study was to evaluate the life-style-related determinants, including diet, on atherosclerosis onset and development. We conducted a cross-sectional analysis of baseline data, including detailed information on dietary habits obtained as part of the overall life-style and risk factor assessment, as well as a complete vascular imaging study that was performed blinded to the clinical information.Results: Most PESA participants follow a Mediterranean (40% of participants) or a Western (41%) dietary pattern. A new pattern, identified among 19% of participants, was labeled as a social-business eating pattern, characterized by a high consumption of red meat, pre-made foods, snacks, alcohol, and sugar-sweetened beverages and frequent eating-out behavior. Participants following this pattern presented a significantly worse cardiovascular risk profile and, after adjustment for risk factors, increased odds of presenting subclinical atherosclerosis (odds ratio: 1.31; 95% confidence interval: 1.06 to 1.63) compared with participants following a Mediterranean diet.Conclusions: A new social-business eating pattern, characterized by high consumption of red and processed meat, alcohol, and sugar-sweetened beverages, and by frequent snacking and eating out as part of an overall unhealthy life-style, is associated with an increased prevalence, burden, and multisite presence of subclinical atherosclerosis.

INTRODUCTION: High cardiorespiratory fitness (CRF) is strongly associated with longer life among older adults. CRF can be assessed by exercise-based methods, which are not feasible in most clinical settings. Thus, nonexercise algorithms to estimate CRF have been developed, but whether they predict mortality in older adults is uncertain. METHODS: A cohort of 1470 men and 1460 women, representative of the Spanish population age ≥60 yr, was established in 2000/2001 and followed up prospectively through 2011. At baseline, nonexercise CRF was estimated with the sex-specific algorithms developed by Jackson et al. Analyses were performed with Cox regression and adjusted for the main confounders. RESULTS: During an average follow-up of 9.4 yr, 570 (38.8%) deaths occurred in men and 295 (20.2%) in women. Among men, no association was observed between nonexercise CRF and all-cause mortality. Compared with women in the lowest quartile of CRF, the hazard ratio (95% confidence interval) for all-cause death was 0.81 (0.62-1.06) in the second quartile, 0.68 (0.48-0.95) in the third quartile, and 0.56 (0.36-0.87) in the highest quartile (P for trend = 0.004). Results held regardless of age, body mass index, waist circumference, HR, subjective health, functional limitations, and disease status. CONCLUSIONS: Higher nonexercise CRF was related to lower risk of death in older women but not in men. Because previous research does not support clear sex-specific association, further research is required to assess whether nonexercise CRF predicts mortality in older adults or new algorithms should be developed for this population, with special attention to older men.

The healthy properties and antioxidant activity of smoked paprika in healthy male non-smoking students (age 20.6 ± 1.7 years), from Universidad de Extremadura (Spain), who consumed (2 g/day, 20 times, over 30 days) smoked (La Vera, Extremadura, Spain) or non-smoked (Novelda, Alicante, Spain) paprika were investigated. Anthropometric and cardiovascular measurements and blood and urine samples were taken from overnight fasted subjects for biochemical, hematological, and immunological measurements. The ingestion of smoked paprika increased the urinary excretion of 1-hydroxypyrene (from 38.6 ± 24.9 to 109.2 ± 85.6 nmol/mol; p < 0.05). Plasma triglyceride and total cholesterol levels were significantly (p < 0.05) reduced after the consumption of either smoked or non-smoked paprika. Plasma lipoperoxidation levels measured both as thiobarbituric acid (3.1 ± 0.5 versus 2.7 ± 0.5 μmol/L; p < 0.05) and as malonaldehyde (0.9 ± 0.4 versus 0.6 ± 0.3 μmol/L; p < 0.01) were reduced after consuming smoked paprika. Plasma levels of carotenoids, lycopenes, vitamin C, vitamin E, and selenium were similar after the ingestion of smoked or non-smoked paprika. The smoked paprika from La Vera seems to produce an antioxidant effect by enhancing the activity of the endogenous antioxidant defenses. [ABSTRACT FROM AUTHOR]
