Moderate egg consumption and all-cause and specific-cause mortality in the Spanish European Prospective into Cancer and Nutrition (EPIC-Spain) study.

PURPOSE: Dietary guidelines for egg consumption for general population differ among public health agencies. Our aim was to investigate the association between egg intake and both all-cause and specific-cause of mortality in a Mediterranean population. METHODS: The European Prospective Investigation into Cancer and Nutrition (EPIC)-Spain cohort included 40,621 men and women aged 29-69 years old in the nineties from 5 Spanish regions. After a mean of 18 years of follow-up, 3,561 deaths were recorded, of which 1,694 were from cancer, 761 from CVD, and 870 from other causes. Data on egg consumption was collected using a validated diet history at recruitment. Cox proportional hazards models, adjusted for confounders, were used in the analyses. RESULTS: The mean (standard deviation) egg consumption was 22.0 g/day (15.8) and 30.9 g/day (23.1) in women and men, respectively. No association was observed between egg consumption and all-cause mortality for the highest vs the lowest quartile (HR 1.01; 95% CI 0.91-1.11; P trend = 0.96). Likewise, no association was observed with cancer and cardiovascular diseases mortality. However, an inverse association was found between egg consumption and deaths for other causes (HR 0.76; 95% CI 0.63-0.93; P trend = 0.003), particularly for deaths from the nervous system (HR 0.59; 95% CI 0.35-1.00; P trend = 0.036). No interaction was detected with the adherence to Mediterranean diet. CONCLUSIONS: This study shows no association between moderate egg consumption, up to 1 egg per day, and main causes of mortality in a large free-living Mediterranean population.

Stabilization and reversal of child obesity in Andalusia using objective anthropometric measures by socioeconomic status.

BACKGROUND: Childhood obesity continues to be a significant public health issue worldwide. Recent national studies in Spain show a stable picture. However, prevalence and trends differ by socio-economic status, age, and region. We present the trend in childhood excess weight prevalence, aged 8-15 years, in Andalusia from 2011-2012 to 2015-2016 by socio-economic status. METHODS: Using the cross-sectional Andalusian Health Surveys, objective anthropometric measures were taken for a representative sample of 8-15 year olds in Andalusia in 2011-2012 and 2015-2016. Prevalence and changes in prevalence of excess weight (overweight plus obesity) were calculated, using both the WHO and IOTF criteria, overall and for sex, age and three different indicators of SES. RESULTS: Overall prevalence of excess weight decreased from 42.0% in 2011-2012 to 35.4% in 2015-2016. Overweight decreased from 28.2 to 24.2% and obesity from 13.8 to 11.2%. In 2011-2012 the prevalence of excess weight in boys was 46.0%and 37.9% in girls; in 2015-2016 the difference became significant with 41% of boys with excess weight compared with 30% in girls. CONCLUSIONS: Childhood excess weight prevalence in Andalusia has decreased slightly between 2011-2012 and 2015-2016. Notably, a decrease in obesity prevalence in girls aged 8-15 years was recorded. In 2011-2012 a social gradient for excess weight prevalence across three SES indicators was observed: in 2015-2016 this gradient disappeared. Nonetheless, prevalence remains too high.

Tendencia de la obesidad infantil y el bajo peso por año de nacimiento y edad en España, 1983-2011 / Trends in child obesity and underweight in Spain by birth year and age, 1983 to 2011

Introducción y objetivos: Las prevalencias de obesidad infantil y sobrepeso están en aumento en todo el mundo y representan un importante problema de salud pública, especialmente en los perfiles de riesgo cardiovascular en la edad adulta si la obesidad no se revierte. La identificación precisa de las tendencias y los subgrupos en riesgo es crucial para orientar correctamente las iniciativas de salud pública. El objetivo de este estudio es examinar los cambios en la obesidad infantil y la prevalencia del bajo peso en España desde 1983 a 2011, teniendo en cuenta la edad y el año de nacimiento. Métodos: Se utiliza una serie de estudios transversales representativos de la población pediátrica en España entre 1987 y 2011, se calcularon la prevalencia y las tendencias de exceso de peso y el bajo peso en niños de 2-14 años, a partir de las encuestas anuales y por año de nacimiento. Resultados: La prevalencia general de sobrepeso y obesidad se mantuvo relativamente estable. La prevalencia del sobrepeso en los varones de 10-14 años aumentó del 13,9 al 22,2%. La prevalencia de la obesidad disminuyó en las mujeres de 2-5 años del 30 al 19,8%, mientras que la prevalencia de bajo peso en este grupo aumentó del 13,7 al 22,6%. Conclusiones: Las tendencias de la obesidad infantil en España durante las últimas 2 décadas parecen mantenerse estables, con algunas fluctuaciones; sin embargo, las tendencias varían en función del sexo y la edad, y se han estabilizado en un nivel alto. La prevalencia de bajo peso también parece haber aumentado y debe considerarse, junto con el exceso de peso, en el diseño y la implementación de las medidas de salud y peso infantiles (AU)

Introduction and objectives: The prevalences of child obesity and overweight are increasing worldwide and are a significant public health issue, particularly in terms of long-term cardiovascular risk profiles, which continue into adulthood unless obesity is reversed. Accurately identifying trends and at-risk subgroups is crucial to correctly target public health initiatives. The objective of this study was to examine changes in the prevalences of child obesity and underweight in Spain from 1983 to 2011 taking into consideration both age and birth year. Methods: A series of cross-sectional studies representative of the pediatric population in Spain between 1987 and 2011 was used to calculate the prevalence and trends of excess weight and underweight in girls and boys aged 2 to 14 years per survey year and per birth year. Results: The overall prevalence of overweight and obesity remained relatively stable. The prevalence of overweight in boys aged 10 to 14 years increased from 13.9% to 22.2%. The prevalence of obesity in girls aged 2 to 5 years decreased from 30% to 19.8%, whereas the prevalence of underweight in this group increased from 13.7% to 22.6%. Conclusions: Child obesity trends in Spain over the last 2 decades appear to be stable with some fluctuations, but the trends differ depending on age and sex, and have stabilized at too high a level. The prevalence of underweight also appears to have increased and should be considered alongside excess weight when designing and implementing child health and weight measures (AU)

Changes in sleep duration in Spanish children aged 2-14 years from 1987 to 2011.

OBJECTIVE: Historical decreases in sleep duration in children have been documented worldwide; however, there is sparse information on sleep duration in differing cultural regions. We assess sleep duration and its trends for children in Spain from 1987 to 2011 and associated sociodemographic characteristics. METHODS: Data from eight Spanish National Health Surveys, from 1987 to 2011, were collected on parent-reported sleep duration and associated socio-demographic characteristics including age, sex, parental level of education, child body mass index (BMI), and physical activity. A total of 24,867 children aged 2-14 years were included in the final sample. RESULTS: Overall, short sleep duration increased to 44.7% from 29.8% in 1987. Decreasing sleep duration trends were found in all demographic groups, decreasing by around 20 minutes in 24 hours from 1987 to 2011; decreasing to 10 hours 16 minutes in 2- to 5-year olds, 9 hours 31 minutes in 6- to 9-year-olds, and 8 hours 52 minutes in 10- to 14-year-olds. No difference in sleep duration was found between girls and boys. Sleep duration was associated with year of survey, age, level of parental education, obesity, and exercise. CONCLUSIONS: Almost 45% of children in Spain are not sleeping the recommended amount. Regional differences in sleep attitudes and duration alongside a lack of consistency in cut-offs for age-appropriate ideal sleep in literature is a barrier for international comparison and highlights the need for research in physiological sleep requirements. With the association of short sleep duration with many different health outcomes, sleep should be considered as a modifiable lifestyle factor and a public health issue.

Factors Influencing Performance-Oriented Mobility After Hip Fracture.

OBJECTIVE: To identify the patient- and fracture-related determinants that influence performance-oriented mobility in hip fracture patients as measured by the Performance-Oriented Mobility Assessment (POMA) score. METHOD: A prospective study was conducted. Patients aged 65 or older (n = 186) were prospectively recruited. Patients were assessed for mobility (Tinetti POMA), level of independence (Modified Barthel Index), emotional distress (Goldberg General Health Questionnaire), comorbidities (Charlson Comorbidity Index), and Perceived Health (categorical scale). RESULTS: The study revealed that patient age, type of fracture, length of hospital stay, level of emotional distress, and level of independence were significant predictors of performance-oriented mobility. When combined, these factors explained 44.3% of the variance in performance-oriented mobility (r(2) = .443; r(2) adjusted = .414; F = 15.46; p < .001). DISCUSSION: Patients who are older, spend more days in hospital, have worse pre-fracture independence level or higher emotional distress levels at discharge, and sustain subtrochanteric or intertrochanteric fractures seem to have poorer performance-oriented mobility after hip fracture.

Individual, family and environmental factors associated with pediatric excess weight in Spain: a cross-sectional study.

BACKGROUND: There is a growing worldwide trend of obesity in children. Identifying the causes and modifiable factors associated with child obesity is important in order to design effective public health strategies.Our objective was to provide empirical evidence of the association that some individual and environmental factors may have with child excess weight. METHOD: A cross-sectional study was performed using multi-stage probability sampling of 978 Spanish children aged between 8 and 17 years, with objectively measured height and weight, along with other individual, family and neighborhood variables. Crude and adjusted odds ratios were calculated. RESULTS: In 2012, 4 in 10 children were either overweight or obese with a higher prevalence amongst males and in the 8-12 year age group. Child obesity was associated negatively with the socio-economic status of the adult responsible for the child's diet, OR 0.78 (CI95% 0.59-1.00), girls OR 0.75 (CI95% 0.57-0.99), older age of the child (0.41; CI95% 0.31-0.55), daily breakfast (OR 0.59; p = 0.028) and half an hour or more of physical activity every day. No association was found for neighborhood variables relating to perceived neighborhood quality and safety. CONCLUSION: This study identifies potential modifiable factors such as physical activity, daily breakfast and caregiver education as areas for public health policies. To be successful, an intervention should take into account both individual and family factors when designing prevention strategies to combat the worldwide epidemic of child excess weight.

Adiposity, mediating biomarkers and risk of colon cancer in the European prospective investigation into cancer and nutrition study.

Adiposity is a risk factor for colon cancer, but underlying mechanisms are not well understood. We evaluated the extent to which 11 biomarkers with inflammatory and metabolic actions mediate the association of adiposity measures, waist circumference (WC) and body mass index (BMI), with colon cancer in men and women. We analyzed data from a prospective nested case-control study among 662 incident colon cancer cases matched within risk sets to 662 controls. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated using conditional logistic regression. The percent effect change and corresponding CIs were estimated after adjusting for biomarkers shown to be associated with colon cancer risk. After multivariable adjustment, WC was associated with colon cancer risk in men (top vs. bottom tertile RR 1.68, 95% CI 1.06-2.65; ptrend = 0.02) and in women (RR 1.67, 95% CI 1.09-2.56; ptrend = 0.03). BMI was associated with risk only in men. The association of WC with colon cancer was accounted mostly for by three biomarkers, high-density lipoprotein cholesterol, non-high-molecular-weight adiponectin and soluble leptin receptor, which in combination explained 46% (95% CI 37-57%) of the association in men and 50% (95% CI 40-65%) of the association in women. Similar results were observed for the associations with BMI in men. These data suggest that alterations in levels of these metabolic biomarkers may represent a primary mechanism of action in the relation of adiposity with colon cancer. Further studies are warranted to determine whether altering their concentrations may reduce colon cancer risk.

Prevalencia de obesidad infantil y juvenil en España en 2012 / Prevalence of child and youth obesity in Spain in 2012

Introducción y objetivos. La obesidad es un importante factor de riesgo cardiovascular. En España son pocos los estudios que hayan realizado una medición física del peso y la estatura para estimar la magnitud del problema. El objetivo de este estudio es determinar la prevalencia de obesidad infantil y juvenil en España en 2012. Métodos. Estudio transversal sobre una muestra probabilística, representativa de la población española, de 978 niños entre los 8 y los 17 años. Se midió objetivamente el peso y la estatura del menor, junto con otras variables sociodemográficas. Se calcularon las prevalencias de sobrepeso y obesidad siguiendo criterios de la Organización Mundial de la Salud, la International Obesity Task Force y el estudio español enKid. Resultados. En el grupo de edad de 8 a 17 años, en 2012 la prevalencia de sobrepeso es del 26% y la de obesidad, del 12,6%; 4 de cada 10 jóvenes sufren exceso de peso. En el grupo comprendido entre los 8 y los 13 años, el exceso de peso supera el 45%, mientras que para el grupo de 14 a 17 años, el exceso de peso es del 25,5%. Este factor de riesgo cardiovascular aparece asociado a las clases sociales más desfavorecidas y con menos estudios. Conclusiones. La prevalencia de sobrepeso y obesidad infantil y juvenil en España sigue siendo muy alta (cercana al 40%), pero no ha crecido en los últimos 12 años (AU)

Introduction and objectives. Obesity is a major cardiovascular risk factor. In Spain, few studies have physically measured height and weight to estimate the magnitude of the problem. The aim of this study was to determine the prevalence of child and adolescent obesity in Spain in 2012. Methods. We performed a cross-sectional probability sample of 1018 children, representative of the Spanish population aged between 8 and 17 years old, with objectively measured height and weight, along with other sociodemographic variables. We calculated the prevalence of overweight and obesity according to the criteria of the World Health Organization, the International Obesity Task Force, and the enKid study. Results. In the group aged 8 to 17 years old, the prevalence of overweight and obesity was 26% and 12.6%, respectively; 4 in 10 young people were overweight or obese. Excess weight was found in 45% of the group aged 8 to 13 years and in 25.5% of that aged 14 to 17 years. This cardiovascular risk factor was associated with lower social class and lower educational level. Conclusions. The prevalence of overweight and obesity in children and adolescents in Spain remains high (close to 40%), but has not increased in the last 12 years (AU)
