Tome medidas para limitar el riesgo de enfermedad cardiovascular

(Family Features) En la última década se ha producido un aumento de factores de riesgo cardiovascular, como la hipertensión arterial no controlada, la diabetes y la obesidad, cada uno de los cuales aumenta el riesgo de desarrollar enfermedades cardíacas y accidentes cerebrovasculares. Estas tendencias están llevando a los investigadores a concluir que la prevalencia de las enfermedades cardiovasculares (ECV) seguirá aumentando.

Más del 60 % de los adultos estadounidenses tendrán algún tipo de ECV para 2050, según las proyecciones previstas de la American Heart Association, que celebra 100 años de servicio salvando vidas como la principal organización mundial sin fines de lucro dedicada a la salud del corazón y el cerebro de todos. Además, se espera que los costos totales relacionados con las ECV casi se tripliquen en ese período hasta alcanzar más de 1.8 trillones de dólares.

El aumento será impulsado por una población más anciana y diversa, pero estos factores de riesgo están aumentando incluso entre niños y adultos.

“Reconocemos que el panorama de la salud cardiovascular cambiará en las próximas tres décadas debido al tsunami que se avecina de aumentos en los costos de la atención médica, una población de mayor edad que vive más tiempo y un número cada vez mayor de personas de poblaciones de pocos recursos”, dijo la voluntaria de la American Heart Association, Karen E. Joynt Maddox, M.D., M.P.H., FAHA. “Aun así, estas siguen siendo las principales causas de muerte y discapacidad en Estados Unidos”.

Si bien se necesitan cambios sistemáticos continuos en la ciencia, las políticas y la atención de salud, la mayoría de las ECV se pueden prevenir a nivel individual. Usted puede ayudar a cambiar el rumbo de las terribles perspectivas de la ECV y, al mismo tiempo, mejorar su propia salud siguiendo y alentando a otros a seguir los “Life’s Essential 8” de la American Heart Association.

Coma mejor. Intente seguir un patrón de alimentación saludable en general que incluya alimentos integrales, frutas y verduras, proteínas magras, frutos secos, semillas y cocinar con aceite de oliva y de canola.

Manténgase activo. Los adultos deben realizar 2 horas y media de actividad física moderada o 75 minutos de actividad física vigorosa por semana. Los niños deben tener 60 minutos cada día, incluidos juegos y actividades estructuradas.

Deje el tabaco. El uso de productos que suministran nicotina por inhalación, que incluyen cigarrillos tradicionales, cigarrillos electrónicos y vaporizadores, es la principal causa de muerte evitable en los EE. UU.

Duerma bien. La mayoría de los adultos necesitan dormir entre 7 y 9 horas cada noche. Los niños de 5 años o menos necesitan entre 10 y 16 horas, incluidas las siestas; de 9 y 12 horas, en niños de 6 y 12 años, y entre 8 y 10 horas, entre los 13 y 18 años.

Controle el peso. Lograr y mantener un peso saludable tiene muchos beneficios. El índice de masa corporal es un indicador útil. El IMC óptimo es menor de 25, pero menor de 18.5 se considera bajo peso. Puede calcularlo en línea o consultar a un profesional de la salud.

Controle el colesterol. Los niveles altos de colesterol no HDL, o “malo”, pueden provocar enfermedades cardíacas. Su profesional de atención médica puede considerar el colesterol no HDL como el número preferido para monitorear, en lugar del colesterol total, porque se puede medir sin ayuno previo y se calcula de manera confiable entre todas las personas.

Controle el nivel de azúcar en sangre. La mayor parte de los alimentos que consume se convierten en glucosa (o azúcar en sangre) que su cuerpo utiliza como energía. Con el tiempo, los niveles altos de azúcar en sangre pueden dañar el corazón, los riñones, los ojos y los nervios.

Controle la presión arterial. Mantener su presión arterial dentro de rangos aceptables puede ayudarle a mantenerse saludable por más tiempo. Los niveles inferiores a 120/80 mmHg son óptimos. La presión arterial alta se define como una presión sistólica de 130 a 139 mm Hg (el número superior en una lectura) o una presión diastólica de 80 a 89 mm Hg (el número inferior).

Exercise

Everyday physical activity, like going for a short walk or playing with the kids, may provide short-term benefits for cognitive health, equivalent to reversing four years of cognitive aging. That was a key finding for my colleagues and me in our new study, which was published in the journal Annals of Behavioral Medicine.

Prior to enrollment into a study of diet and dementia risk, we asked a diverse sample of 204 middle-aged adults to check in five times per day for a period of nine days, via a smartphone application.

Each check-in involved completing a brief survey that asked about their mood, dietary choices and whether they engaged in any physical activity in the roughly three and a half hours leading up to the survey. In addition, participants completed a few brief brain games – meaning performance-based cognitive assessments that lasted about one minute each – to assess mental speed and short-term memory.

My team found that performance on our measure of cognitive processing speed improved during check-ins when participants reported being physically active in the time leading up to the survey. While we didn’t see improvements in our measure of working memory, the time taken to complete the memory task mirrored what we saw for the measure of processing speed.

We observed these improvements in speed regardless of whether the activity was lighter intensity or moderate-to-vigorous intensity. This led us to conclude that movement, whether it took the form of intentional exercise or part of a daily routine, was the essential ingredient for achieving this benefit.

Why it matters

As a rule, we get slower, both physically and mentally, as we age. While research on exercise and living a healthy lifestyle has demonstrated the long-term cognitive and brain health benefits of remaining physically active, much of this work has focused on the moderate- to vigorous-intensity physical activity – or what most of us think of as exercise – recommended by the Physical Activity Guidelines for Americans.

Still, these guidelines and other experts recommend that adults move more and sit less.

My colleagues and I are interested in understanding how moving more can improve our cognitive health or reduce our risk of dementia as we age, at what timescale these benefits show up, and what types of movement qualify. https://www.youtube.com/embed/lk3mrNqhn24?wmode=transparent&start=0 Exercise promotes blood circulation and the growth of neurons.

What still isn’t known

Our study relied on participants to report whether they had been physically active during the time between each check-in. Even though participants were provided training on how to think about the intensity levels, it’s possible that each participant had a slightly different perception of their activities.

For example, a participant may not have believed their recent walk actually qualified as a moderate-intensity activity. Physical activity monitors that can dissociate time and intensity might help future research unravel these associations more clearly.

What’s next

It isn’t yet clear whether these short-term benefits accumulate over time to result in long-term improvements in brain health and dementia risk reduction. Research efforts are underway by our team to better understand these associations over broader timescales.

My research involves data collection via smartphones and wearable devices to help us better understand how health-promoting behaviors and cognitive health interact as we age. This type of digital approach allows my team to pursue questions about how everyday behavior and experience influence cognition in daily life and represents a significant methodological advancement in the dementia risk and prevention research space.

Using these tools, we aim to better identify individuals at risk for negative cognitive outcomes and new targets for dementia prevention.

Most senior citizens get around in their daily lives by driving, walking or using public buses and subways. But many people in their 60s and 70s could potentially be interested in other options, such as cycling. At a time when cycling is growing in the U.S. and the overall population is aging, seniors’ preferences for bike designs and bike networks are very relevant.

Older people may have concerns about riding a two-wheeled bike if they are afraid of falling – a risk that increases with age and causes many seniors to become less active. Many cities and communities are working to create safer bike networks, but these are designed for young, physically fit bikers, who are less afraid to bike near cars and don’t need an occasional bathroom break.

Some seniors live in assisted living complexes or memory care facilities that have roads, sidewalks and paths for residents pushing walkers. However, these complexes don’t usually have bike storage rooms, bike loops or safe bike pathways to local parks and stores.

I am a researcher in architecture – with a focus on environment and behavior – and a senior, and I have studied bikes and bike networks for over 43 years. In my latest project, I worked with Seth Gale, a behavioral neurologist; Linda Mazie, a health and wellness coach who works with seniors; and Heidi Savage, a fitness director who also works with seniors, to learn from older people what kinds of bicycles and bike networks would help them stay active and independent through cycling. https://www.youtube.com/embed/vrrzFnzYUXI?wmode=transparent&start=0 In the Netherlands, where many people of all ages routinely ride bikes, local officials take a tour with older riders to identify spots that seniors find particularly unsafe on their route.

We found that a majority of the seniors whom we surveyed and who test-rode three bikes preferred a three-wheeled adult tricycle or a two-seat model that lets riders sit side by side. For infrastructure, their key requirements included bike loops, separation from cars and nearby bathrooms.

Benefits of biking for seniors

Many older people in the U.S. don’t get enough physical activity for healthy aging. A 2016 study by the Centers for Disease Control and Prevention found that more than one-fourth of all adults over 50 did not engage in any physical activity outside of work. This share increased with age and was higher among people with chronic diseases such as cancer, diabetes and depression. Inactivity was significantly higher among women than men, and among Black and Hispanic seniors compared with white seniors.

Biking provides many health benefits, including cardiovascular exercise, stronger muscles, better coordination and lower stress levels. It also offers benefits that are particularly relevant for seniors. For example, one study found that cycling for at least one hour per week significantly improved older people’s balance, potentially making them less vulnerable to falls.

There also are findings suggesting that exercise may help slow the progression of Alzheimer’s disease. For example, one study showed that when mice exercised on a wheel, their muscles produced irisin, a hormone that supports cognitive function. The irisin passed into their brain, improving memory and spatial awareness.

Senior-friendly bikes

For our study, we distributed surveys with pictures of senior-friendly bikes and questions about bike networks to 178 seniors in four senior communities in Massachusetts and New Hampshire. Participants ranked the pictures according to how well they liked the various bike designs and offered more comments while seeing the pictures on a large screen.

We also borrowed three senior-friendly bikes made by Van Raam, a Dutch company that designs bikes for a wide range of special needs. These models included:

• A three-wheeled bike for side-by-side riders who each have handlebars and who can pedal together while one steers.
• An adult tricycle with a back rest and low center of gravity.
• A two-wheeled bike with a low center bar that makes it easy to step through when getting on or off.

Fifty seniors at RiverWoods-Exeter, a senior living complex in New Hampshire, and Fox Hill Village, an independent living community for seniors in Westwood, Massachusetts, were invited to test-ride the three models and complete a survey about their experiences.

Designing bike networks for older riders

Based on photos, participants were most enthusiastic about the adult tricycle and also were interested in the two-seat three-wheeler. Adult tricycles are harder to pedal than bikes with two wheels, and rounding corners involves turning the handlebars without leaning, so these models have a learning curve. However, they offer stability, which clearly was important to the people in our study.

Among seniors who did test rides, the most popular model was the single-seat three-wheeled bike. Unlike a low recumbent bicycle, this bike’s seat is about as high as a chair, and unlike an adult tricycle, it has a back rest.

Participants’ second choice was the three-wheeled two-seater bike, which has seats with backs, arm rests and seat belts. Fewer participants were willing to test-ride the two-wheeled regular bike with a low center bar; those who tried it were already comfortable riding two-wheeled bikes.

Comments were enthusiastic, especially for the two-seater bike. Seniors wrote, “I like the social aspect and teamwork”; “I see this as an asset to our community”; and, simply, “Awesome!!!”

Some noted that the two-seater could work for seniors who were caregivers for their spouses. One husband wrote, “This would be great to ride with my wife, who hasn’t ridden a bike for 50 years.”

In response to survey questions about the most important features of a senior-friendly bike network, participants said they wanted to be able to bike for 30 minutes at a stretch, ride twice a week and have a bathroom available.

For a network added to their assisted living complexes, they wanted a cycling loop on-site; a route to a destination outside the complex; a smooth, flat riding surface with grass shoulders; and picnic tables and water nearby. Participants felt that cars traveled too fast in their residential complexes, so they wanted to ride on separated paths rather than on existing roads.

Our findings echo other studies that have shown that senior cyclists want to ride in protected bike lanes or separate paved paths, rather than in street traffic. Because many seniors have limited vision, another feature that can make bike paths safer for them is light-colored demarcation strips at the edges of the path to help older riders avoid veering off the main cycle path, especially at night.

Pedaling ahead

Here are the key steps that I believe would be required to develop findings like ours into scalable bicycling programs for seniors in the U.S.

Some seniors might appreciate having classes to relearn how to ride a two-wheeled bike, or to ride with another person on a two-seater model. Assisted living complexes could install bike storage sheds and buy several senior-friendly bikes for residents to ride.

Protected bike lanes could be made more senior-friendly by building them level with the adjoining sidewalk, so that a third wheel could rest on the edge of the parallel sidewalk. Lanes optimized for senior riders would be continuous and have bicycle traffic signals, raised crosswalks and nearby public bathrooms with signs leading to them.

Routes could run from residential neighborhoods to destinations such as coffee shops, post offices, grocery and drugstores, and parks. Destinations could provide space to park and lock the bikes while riders shopped or had coffee.

The U.S. has an aging population, and seniors’ health is an important concern for seniors themselves, their caregivers and taxpayers. There is strong evidence that increased bicycle use by seniors could help many people live healthier and more independent lives well into their golden years.
