Living healthier for longer: comparative effects of three heart-healthy behaviors on life expectancy with and without cardiovascular disease

Background: Non-smoking, having a normal weight and increased levels of physical activity are perhaps the three key factors for preventing cardiovascular disease (CVD). However, the relative effects of these factors on healthy longevity have not been well described. We aimed to calculate and compare the effects of non-smoking, normal weight and physical activity in middle-aged populations on life expectancy with and without cardiovascular disease. Methods: Using multi-state life tables and data from the Framingham Heart Study (n = 4634) we calculated the effects of three heart healthy behaviours among populations aged 50 years and over on life expectancy with and without cardiovascular disease. For the life table calculations, we used hazard ratios for 3 transitions (No CVD to CVD, no CVD to death, and CVD to death) by health behaviour category, and adjusted for age, sex, and potential confounders. Results: High levels of physical activity, never smoking (men), and normal weight were each associated with 20-40% lower risks of developing CVD as compared to low physical activity, current smoking and obesity, respectively. Never smoking and high levels of physical activity reduced the risks of dying in those with and without a history of CVD, but normal weight did not. Never-smoking was associated with the largest gains in total life expectancy (4.3 years, men, 4.1 years, women) and CVD-free life expectancy (3.8 and 3.4 years, respectively). High levels of physical activity and normal weight were associated with lesser gains in total life expectancy (3.5 years, men and 3.4 years, women, and 1.3 years, men and 1.0 year women, respectively), and slightly lesser gains in CVD-free life expectancy (3.0 years, men and 3.1 years, women, and 3.1 years men and 2.9 years women, respectively). Normal weight was the only behaviour associated with a reduction in the number of years lived with CVD (1.8 years, men and 1.9 years, women). Conclusions: Achieving high levels of physical activity, normal weight, and never smoking, are effective ways to prevent cardiovascular disease and to extend total life expectancy and the number of years lived free of CVD. Increasing the prevalence of normal weight could further reduce the time spent with CVD in the population

The relation between non-occupational physical activity and years lived with and without disability

Objectives: The effects of non-occupational physical activity were assessed on the number of years lived with and without disability between age 50 and 80 years. Methods: Using the GLOBE study and the Longitudinal Study of Aging, multi-state life tables were constructed yielding the number of years with and without disability between age 50 and 80 years. To obtain life tables by level of physical activity (low, moderate, high), hazard ratios were derived for different physical activity levels per transition (non-disabled to disabled, non-disabled to death, disabled to non-disabled, disabled to death) adjusted for age, sex and confounders. Results: M

Physical activity and life expectancy with and without diabetes: life table analysis of the Framingham Heart Study

OBJECTIVE: Physical activity is associated with a reduced risk of developing diabetes and with reduced mortality among diabetic patients. However, the effects of physical activity on the number of years lived with and without diabetes are unclear. Our aim is to calculate the differences in life expectancy with and without type 2 diabetes associated with different levels of physical activity. RESEARCH DESIGN AND METHODS: Using data from the Framingham Heart Study, we constructed multistate life tables starting at age 50 years for men and women. Transition rates by level of physical activity were derived for three transitions: nondiabetic to death, nondiabetic to diabetes, and diabetes to death. We used hazard ratios associated with different physical activity levels after adjustment for age, sex, and potential confounders. RESULTS: For men and women with moderate physical activity, life expectancy without diabetes at age 50 years was 2.3 (95% CI 1.2-3.4) years longer than for subjects in the low physical activity group. For men and women with high physical activity, these differences were 4.2 (2.9-5.5) and 4.0 (2.8-5.1) years, respectively. Life expectancy with diabetes was 0.5 (-1.0 to 0.0) and 0.6 (-1.1 to -0.1) years less for moderately active men and women compared with their sedentary counterparts. For high activity, these differences were 0.1 (-0.7 to 0.5) and 0.2 (-0.8 to 0.3) years, respectively. CONCLUSIONS: Moderately and highly active people have a longer total life expectancy and live more years free of diabetes than their sedentary counterparts but do not spend more years with diabetes

Case studies for a new IoT programming paradigm: Fluidware

A number of scientific and technological advancements enabled turning the Internet of Things vision into reality. However, there is still a bottleneck in designing and developing IoT applications and services: each device has to be programmed individually, and services are deployed to specific devices. The Fluidware approach advocates that to truly scale and raise the level of abstraction a novel perspective is needed, focussing on device ensembles and dynamic allocation of resources. In this paper, we motivate the need for such a paradigm shift through three case studies emphasising a mismatch between state of art solutions and desired properties to achieve

Sedentary behaviors, physical activity behaviors, and body fat in 6-year-old children: The Generation R Study

Background: Childhood overweight and obesity is a major public health concern. Knowledge on modifiable risk factors is needed to design effective intervention programs. This study aimed to assess associations of children's sedentary behaviors (television viewing and computer game use) and physical activity behaviors (sports participation, outdoor play, and active transport to/from school) with three indicators of body fat, i.e., percent fat mass, body mass index (BMI) standard deviation scores, and weight status (normal weight, overweight). Methods: Cross-sectional data from 5913 6-year-old ethnically diverse children were analyzed. Children's weight and height were objectively measured and converted to BMI. Weight status was defined according to age- and sex-specific cu

Social inequalities in young children's meal skipping behaviors: The Generation R Study

Background: Regular meal consumption is considered an important aspect of a healthy diet. While ample evidence shows social inequalities in breakfast skipping among adolescents, little is known about social inequalities in breakfast skipping and skipping of other meals among young school-aged children. Such information is crucial in targeting interventions aimed to promote a healthy diet in children. Methods: We examined data from 4704 ethnically diverse children participating in the Generation R Study, a population-based prospective cohort study in Rotterdam, the Netherlands. Information on family socioeconomic position (SEP), ethnic background, and meal skipping behaviors was assessed by parent-reported questionnaire when the child was 6 years old. Multiple logistic regression analyses were performed to assess the associations of family SEP (educational level, household income, employment status, family composition) and ethnic backgr

LA INNOVACIÓN LOCAL EN LA DINAMICA DEL CONOCIMIENTO TRADICIONAL Y CIENTÍFICO DE LA COMUNIDAD DE ARTESANOS DE MADERA EN DZITYÁ, YUCATÁN

En México, como en muchos de los países en desarrollo, la capacidad de generar innovaciones parece nula, sin embargo, la innovación está presente en todo momento sólo que, en menor escala. También, se tiene la percepción que la innovación se refiere únicamente a la generación de desarrollos tecnológicos como las TIC´s o grandes maquinarias que aumentan la productividad, y también se percibe que los países desarrollados son los únicos capaces de generar innovaciones. Como consecuencia, se ha prestado poca atención a la capacidad de innovación local, así como las prácticas de gestión y técnicas desarrolladas por las comunidades y otros actores locales sobre la base de sus conocimientos tradicionales y su integración con el conocimiento científico. En este sentido, este documento no se centra en los resultados de una investigación científica sobre la existencia de sistemas de innovación, sino más bien, en cómo las comunidades locales, con el escaso acercamiento a instituciones académicas y gubernamentales, extrae conocimiento y los combina con su propio conocimiento generando innovación en sus prácticas locales. La innovación, como se explicará en este artículo, es la capacidad de los artesanos locales de madera de Dzityá, Yucatán, quienes desempeñan un papel activo en la creación de conocimientos con el fin de mejorar las prácticas artesanales de torneado de madera y su relación con la conservación del medio ambiente para así propiciar su desarrollo local con una perspectiva sustentable

Meal-Skipping Behaviors and Body Fat in 6-Year-Old Children

Objective To assess the prospective associations of breakfast, lunch, and dinner skipping at age 4 years with body fat (ie, percent fat mass, body mass index [BMI], and weight status) at age 6 years. Study design Data were analyzed from 5913 children participating in the Generation R Study, a population-based prospective cohort study in Rotterdam, The Netherlands. Meal-skipping behaviors were assessed through parent-report questionnaires. Children's weight and height were objectively measured and converted to BMI SDSs. Weight status (ie, overweight or normal weight) was defined according to age- and sex-specific cutoff points. At age 6 years, percent fat mass was assessed by dual-energy X-ray absorptiometry. Linear and logistic regression analyses were performed, adjusting for covariates and BMI at age 4 years. Results Breakfast skipping at age 4 years was associated with a higher percent fa
