I described the typical causes and treatments for seasonal allergies, as well as dispelled some allergy myths, in the April 2014 issue of American Legion magazine.
Here’s the gist of the article in the magazines “Living Well” section below:
Seasonal allergies such as hay fever are the most common type of an allergy, which is an overreaction of your immune system to a foreign substance (“allergen”).
This immune overreaction can result in symptoms, such as coughing, sneezing, itchy eyes, runny nose, and scratchy throat.
In severe cases of skin, food, latex, insect, or eye allergies, it can lead to rashes, hives, lower blood pressure, difficulty breathing, asthma attacks, and even death.
Knowing exactly what you are allergic to can help you lessen or prevent exposure, and treat your reactions.
Allergy skin testing, considered the most sensitive testing method, provides rapid results.
The most common test involves pricking the skin with the extract of a specific allergen, then observing the skin’s reaction.
Blood tests can also provide similar information to allergy skin testing.
The best treatment for allergies is to avoid the offending allergens.
If you are allergic to a specific food like peanuts, remove them from your diet (be careful for hidden peanuts in foods).
That’s not so easy when you are allergic to ragweed pollen in the air.
Various over-the-counter or prescription medications can relieve the common symptoms of hay fever.
These medications counter the effects of histamine, the substance that makes your eyes water, nose itch, and causes you to sneeze.
Newer antihistamines do not cause the sleepiness that was a problem with older versions.
These anti-inflammatory sprays help decrease inflammation, swelling, and mucus production.
They work well alone or in combination with antihistamines, and are relatively free of side effects.
This nasal spray also helps stop hay fever, perhaps by blocking release of histamine and other symptom-producing chemicals.
It has few side effects.
Available in capsule and spray form, these drugs may reduce swelling and sinus discomfort.
They are intended for short-term use, and usually are used along with antihistamines.
Be aware that long-term use of decongestant sprays can make your symptoms worse.
Also known as immunotherapy, these might help if you don’t get relief with antihistamines or nasal steroids.
These shots alter the body’s immune response and help to prevent allergic reactions.
They are the only form of treatment that induces long-lasting protection.
But immunotherapy treatments are limited because of potential allergic reactions, which can be severe.
Allergy Myths and Misconceptions
Common myths and misconceptions about allergies persist due to false information in the media and online.
David Stukus, MD, an allergist at Nationwide Children’s Hospital in Columbus, OH, outlines some of the greatest myths.
1. “I’m Allergic to Artificial Dyes” – There is no scientific evidence to support a link between exposure to artificial coloring and allergies.
2. “I Cannot Have Vaccines Due to an Egg Allergy” – Egg embryos are used to grow viruses for vaccines such as the flu, yellow fever, and rabies shots. But it’s safe to get a flu shot, which can help prevent serious illness.
3. “At-Home Blood Tests Reveal All You Are Allergic To” – These tests might reveal sensitization, for example, to milk, but that doesn’t mean you are necessarily allergic to it.
4. “I’m Allergic to Cats and Dogs, but Can Have a Hypoallergenic Breed” – There is no such thing as a truly hypoallergenic cat or dog.
It’s not the fur you may be allergic to but the allergens released in saliva and glands.
5. “I’m Allergic to Shellfish and Cannot Have Iodine Imaging” – Some physicians have linked a reaction to iodine dye used in imaging tests to a shellfish allergy.
But iodine cannot be an allergen since it is found in the human body.
6. “I Can’t have Bread, I’m Allergic to Gluten” – Many people claim to have a gluten allergy.
You may have gluten intolerance, but it’s extremely rare to have a true allergy to wheat-based foods.
If you think you may have an allergy, Dr. Stukus recommends that you see a board-certified allergist for proper evaluation, testing, diagnosis, and treatment.
Weight loss and other lifestyle interventions can reduce the risk of long-term cardiovascular consequences of diabetes, according to the results of a clinical trial.
This is the first randomized clinical trial to show that lifestyle intervention in those with impaired glucose tolerance reduces all-cause and cardiovascular disease mortality.
“Lifestyle intervention delays the onset of diabetes and reduces the incidence of diabetes.
We had assessed how mortality was affected by the time free from diabetes, which was defined as the time between randomization and onset of diabetes.
We found that the increased delay in the onset of diabetes was associated with significantly lower all-cause and cardiovascular disease mortality,” said lead author Professor Guangwei Li of the China-Japan Friendship Hospital, Beijing, China.
“After inclusion of time to onset of diabetes in the multivariable models the intervention variable was no longer statistically significant, suggesting that the reduction in mortality associated with the intervention is mediated by its effect in delaying the onset of diabetes,” he noted.
The researchers published their results online on April 3, 2014 in The Lancet Diabetes & Endocrinology.
LIFESTYLE INTERVENTIONS PREVENT DEATHS
Many research studies have shown that lifestyle interventions, such as exercise programs or weight loss, in persons with impaired glucose tolerance can prevent progression to overt type 2 diabetes.
However, until now, there has been a lack of high-quality, randomized controlled trial evidence to prove that lifestyle interventions prevent deaths from cardiovascular disease, such as heart attacks and stroke, in these patients.
Dr. Li and colleagues enrolled 438 patients assigned to the intervention arm and 138 patients who were assigned to the control arm.
The study intervention lasted for 6 years, and patients were then monitored for 23 years.
At the end of the follow-up period, cumulative incidence of death from cardiovascular disease was 11.9% in the lifestyle intervention group versus 19.6% in the control group.
Death from all causes was 28.1% in the lifestyle group versus 38.4% in the control group.
The difference between groups for both outcomes was statistically significant.
“Although the association between duration of diabetes and mortality is well established, serious chronic complications and excess mortality typically only occur after at least 10 years of having diabetes,” Dr. Li said.
“In the present study, a difference in mortality between the intervention and control group started to emerge 12 years after the study began, slowly increased to a 17% difference by the 20-year follow-up, but became statistically significant only after 23 years.”
“TYPE 2 DIABETES CAN BE PREVENTED”
Dr. Li noted that a key difference between previous other studies and the Da Qing Diabetes Prevention Study is the length of follow-up.
In previous studies, the length of follow-up might have been insufficient to detect an effect of intervention on mortality.
Dr. Li’s bottom-line message: “Type 2 diabetes can be prevented.
Group-based lifestyle interventions over a 6-year period have long-term effects on prevention of diabetes beyond the period of active intervention.
The benefits of the intervention extended to a significantly favorable reduction of mortality.
These results emphasize the long-term benefits of the intervention and reinforce the overall value and importance of lifestyle interventions as public health strategies to prevent diabetes.”
If you have migraine headaches, they may increase significantly after you relax and then experience heightened stress, according to the results of a new study.
“People with migraine are thought to inherit a predisposition to headaches.
Attacks of migraine headache are initiated in vulnerable individuals when they are exposed to a broad range of triggers,” said study co-author Dawn C. Buse, PhD, Director of Behavioral Medicine, Montefiore Headache Center, and Associate Professor, Clinical Neurology, at the Albert Einstein College of Medicine in New York.
“Our study results support the ‘letdown phenomenon,’” she said.
“That is, relaxation following high perceived stress is a powerful predictor of migraine onset.”
The researchers published their results online on March 26, 2014 in the journal Neurology.
MIGRAINE DIARIES COLLECT TRIGGERS
Dr. Buse and colleagues asked 17 patients with migraine to keep electronic diaries for 3 months to examine the relationship of perceptions of stress and relaxation after stress with increased probability of a migraine attack, yielding more than 2000 diary entries, including 110 eligible migraine attacks.
Data were collected using a custom-programmed electronic diary.
Each day patients recorded information about migraine attacks, 2 types of stress ratings, and common migraine triggers.
Triggers included hours of sleep; certain foods, drinks, and alcohol consumed; and menstrual cycle.
They also recorded their mood each day, including feeling happy, sad, relaxed, nervous, lively, and bored.
“We found that a reduction in stress from one day to the next was associated with a nearly 5-fold increased risk of migraine onset within 6 hours,” Dr. Buse said.
The biology of stress is complex, including activation of both neuroendocrine and sympathetic mechanisms, she noted.
“Cortisol rises during times of stress.
If cortisol falls in periods of relaxation after stress that may contribute to the triggering of a migraine attack,” said lead author Richard B. Lipton, MD, Director, Montefiore Headache Center, and Professor and Vice Chair of Neurology and the Edwin S. Lowe Chair in Neurology at Einstein.
STRATEGIES TO REDUCE STRESS
“This study highlights the importance of stress management and healthy lifestyle habits for people who live with migraine,” Dr Buse stated.
“It is very important for people to be aware of rising stress levels and attempt to relax during periods of stress rather than allow a major buildup to occur.
Strategies to relax could include exercising, attending a yoga class, taking a walk with your dog, or simply focusing on your breath for a few minutes.”
Behavioral interventions that protect against rising levels of stress also may prevent the peak followed by the valley that leads to an increased risk of migraine attack.
“There are several approaches to stress management with strong scientific support, including cognitive behavioral therapy (CBT), biofeedback, and relaxation therapies,” Dr. Buse said.
“An additional bonus is that these techniques also have scientific evidence for migraine prevention.”
Some approaches require the guidance of a mental health care professional, such as biofeedback and CBT, and some can be self-learned, such as diaphragmatic breathing and guided visual imagery.
“Once learned these techniques can be practiced practically anywhere at any time for the rest of someone’s life,” Dr. Buse noted.
“Based on these findings, we suggest that health care professionals caring for individuals with migraine should incorporating stress management interventions into treatment plans, especially for patients for whom changes in stress levels are triggers for migraine attacks.”
Good cardiovascular health may help preserve memory and thinking skills into middle age, according to the results of a new study.
“The brain health of young adults shows benefits from cardio fitness activities.
Interestingly, for those who currently have low fitness, even activities at moderate intensity are likely to be beneficial.
For couch potatoes, it’s just getting moving,” said David R. Jacobs, Jr, PhD, Professor, School of Public Health, Division of Epidemiology & Community Health at the University of Minnesota, MN.
“The brain, like all organs, is highly vascularized,” he said.
“Factors that affect the health of the vascular system are likely to affect the health of the brain.
There is substantial evidence that many cardiovascular disease risk factors also reduce chronic low grade inflammatory conditions.”
The researchers published their results online on April 2, 2014 in the journal Neurology.
TREADMILL AND COGNITIVE TESTS
For the study, more than 2700 healthy persons, average age 25 years, underwent treadmill tests in the first year and then again 20 years later.
Cognitive tests conducted 25 years after the start of the study measured verbal memory, psychomotor speed (the relationship between thinking skills and physical movement), and executive function.
Those who had smaller decreases in their time completed on the treadmill test 20 years later were more likely to perform better on the executive function test than those who had bigger decreases.
“Of course, the executive function, memory skill, and speed of processing that we studied in relation to treadmill test–based fitness are not the same as real life situations,” said Dr. Jacobs.
“However, the standardized testing is useful and can be considered to represent ‘thinking skills.’
Other studies in older individuals have shown that these tests are among the strongest predictors of developing dementia in the future.”
Dr. Jacobs noted that many chronic diseases have their roots many years before clinical manifestation.
“It is logical that people who experience mild losses of cognitive function are at risk for dementia,” he said.
“This has been shown at older ages.
However, we do not know whether the ‘thinking skills’ that we measured will lead to the more severe manifestations that are devastating our elderly population.”
He continued: “It will take further follow-up over another 10 to 20 years to discover empirically whether the cognitive losses that we measured are in fact a risk for dementia.
DIMINISHED ‘THINKING SKILL’ IN MIDDLE AGE
At minimum, I speculate that people who suffer less ‘thinking skill’ in middle age do not function as effectively in society as people who remain sharp.”
The study pointed out how middle age (defined as age 43 to 55 years) and elderly chronic disease in the brain may have roots in lifestyle behaviors during youth.
Dr. Jacobs noted that the current study does not address whether improving fitness would reduce the loss of cognitive function.
“Fitness performance on a symptom-limited treadmill test is dependent on many factors, including vigorous activity, musculoskeletal health, general robustness, smoking, adiposity, and social participation,” he said.
“This is not the same as a group activity that requires exercising or just moving around.
However, encouraging patients to exercise and in general to maintain an active, engaged lifestyle may help forestall cognitive loss, among other benefits.”
Two new studies show the heart-healthy benefits of eating a Mediterranean diet.
One study linked the diet to a lower risk of diabetes, especially among those at high risk for cardiovascular disease.
The other study tied the eating plan to lower levels of platelets and white blood cells, 2 markers of inflammation, which has been associated with a greater risk of heart attack and stroke.
The Mediterranean diet frequently emphasizes fresh fruits and vegetables, whole grains, beans, nuts, fish, olive oil, and even a glass of red wine.
Eating an anti-inflammatory, Mediterranean style diet has been shown to not only be a delicious and enjoyable way to eat, but also is wonderful for your health.
Earlier research has shown that following the traditional Mediterranean diet also is linked to weight loss, a reduced risk of heart disease and related death, and lower blood pressure and blood cholesterol levels.
Mediterranean Diet Reduces Risk of Diabetes
In the first pooled analysis of studies evaluating the possible role of the Mediterranean diet in diabetes development, adherence to this diet was associated with a 21% reduced risk of diabetes compared with the control dietary groups.
The likelihood of developing diabetes was almost 27% less in those at high risk for cardiovascular disease than in controls.
“Adherence to the Mediterranean diet may prevent the development of diabetes irrespective of age, sex, race, or culture,” said lead investigator Demosthenes Panagiotakos, PhD, professor at Harokopio University, Athens, Greece.
“This diet has a beneficial effect, even in high risk groups, and speaks to the fact that it is never too late to start eating a healthy diet.”
Dr. Panagiotakos and colleagues systematically reviewed 19 original research studies that followed more than 162,000 participants for an average of 5.5 years.
These studies spanned European and non-European populations, which is important because most of the published studies have been European-based and there has been some question of possible confounding factors in these regions, including genetics, the environment, lifestyle, and lower stress levels.
Dr. Panagiotakos said he believes the Mediterranean diet lowers the risk of diabetes by helping guard against obesity.
He presented his study on March 27, 2014 at the American College of Cardiology’s 63rd Annual Scientific Session in Washington, DC.
Mediterranean Diet Lowers Inflammation
To understand whether a Mediterranean diet might favorably influence platelet and white blood cell levels, Italian researchers conducted an analysis of the eating habits of nearly 15,000 healthy Italian men and women aged 35 years or older as part of a large epidemiological study.
The investigators observed that consumption of the Mediterranean diet was directly related to lower levels of platelets and white blood cells, which in turn correlated to lower levels of inflammation.
Those who strictly followed a traditional Mediterranean diet were less likely to belong to study cohorts with relatively high platelet counts and were more likely to belong to cohorts with relatively low white blood cell counts.
“Because the study included healthy participants, the lower levels of platelets and white blood cells in those who were more strictly consuming a Mediterranean diet indicate that this eating plan could account for substantial changes within normal ranges of variability,” said lead author Marialaura Bonaccio, PhD.
“This is an important finding that has implications for how these anti-inflammatory markers are tracked among the general population.”
Dr Bonaccio is with the Department of Epidemiology and Prevention at the IRCCS Istituto Neurologico Mediterraneo NEUROMED in Italy.
The results of her study were published online in the March 31, 2014 issue of Blood.
A good friend of mine’s son is backing playing Ultimate frisbee, having torn up his knee last spring playing Freshman football in high school.
Reconstructive surgery repaired Sam’s two torn knee ligaments, including the anterior cruciate ligament (ACL), a critical ligament that stabilizes the knee joint.
ACL injuries are quite common among young athletes and have become more prevalent over the past decade as more youngsters participate in sports such as football, soccer, volleyball, and basketball, which are hard on the knees.
Recent research has found that screening tools, such as “hop” or isokinetic (computer/video) tests to identify neuromuscular deficits, may identify athletes more likely to suffer ACL injuries.
Biomechanical studies have led to the development of neuromuscular training programs to improve neuromuscular control and reduce ACL injury rates.
Now research led by doctors from New York-Presbyterian/Columbia University Medical Center has found that universal neuromuscular training — which focuses on the optimal way to bend, jump, land, and pivot the knee — is an effective and inexpensive way for young athletes to avoid ACL sprains and tears.
The researchers reported their results at the American Academy of Orthopedic Surgeons annual meeting on March 14, 2014.
The research team evaluated 3 strategies for young athletes: no training or screening, universal neuromuscular training, and universal screening with neuromuscular training only for identified high-risk athletes.
Risk of injury, risk reduction from training, and sensitivity and specificity of screening were based on published data from clinical trials.
Costs of training and screening programs were estimated based on existing literature.
Using a model based on data from recent clinical trials, the researchers evaluated a hypothetical group of student athletes ages 14 to 22.
They found that universal training reduced the incidence of ACL injury on average by 63% while the screening program reduced the incidence rate on average by 40%.
Of 10,000 athletes, the model predicted 300 ACL injuries in the no-screening group, 110 in the universal training group, and 180 in the universal training/screening for “at risk” group.
What’s more, by reducing the risk of ACL injury universal training would save an average of $275 per player per season.
“While we were not surprised that training was more cost effective than no intervention, we were impressed by the magnitude of the benefit,” said lead researcher Dr. Eric Swart, an orthopedic resident at New York-Presbyterian/Columbia University Medical Center.
“According to our model, training was so much less expensive and so much more effective than we anticipated.
In addition, fewer players injured means fewer surgical reconstruction procedures, which also saves money.”
He believes that widely implementing a universal training strategy could actually pay for itself in terms of injuries prevented and surgeries avoided.
And that’s doesn’t include saving youngsters from the pain and anguish of recovering from major surgery.
Neuromuscular training may be too late for Sam, who continues to do physical therapy to strengthen his leg muscles to support his rebuilt knee.
But thousands of other young athletes could certainly benefit from better training to avoid devastating knee injuries.
National Day of Unplugging starts tonight, offering us a chance to disconnect from technology and reconnect with family and friends.
Today’s guest blog comes from occupational therapist Robbie Levy, a highly respected authority in her field who has been successfully working with children since 1981.
Robbie was ahead of her time when she recognized the importance of early intervention and the need for therapeutic resources dedicated to children.
She founded Dynamic Kids, one of the leading pediatric occupational therapy practices in the New York region.
Below, she presents some cogent thoughts on why kids need to unplug, and how you can help them go about it.
There is no denying the media, the Internet, video games, and computers are all part of our daily lives.
We use these electronic devices for a variety of reasons: for work, to assist us in our everyday routines, to keep up with friends, and for play and recreation.
For the most part, technological advancements have improved society.
But what effects do these gadgets really have on young children’s’ development as they grow?
According to the American Academy of Pediatrics, children spend an average of 7 hours a day on entertainment media.
Limit Kids Screen Time
As a parent, it is crucial to limit children’s screen time and offer only educational media and non-electronic formats, such as books, board games, and sensory motor activities.
If your young child does use media, watch together and then talk about what you saw.
Or sing the songs together.
This will help guide your children to a better media experience.
In a child’s first 5 years of life, the brain grows rapidly.
Young children learn best by interacting with other people and directly from sensory and motor play with their bodies utilizing all their senses.
National Day of Unplugging from sundown on Friday, March 7th to sundown on Saturday, March 8th allows us 24 hours to reconnect with our children, family, and friends (and self) without the interference of technology.
As an Occupational Therapist and child development specialist for 33 years, I assure you this is a wonderful opportunity to unwind, de-stress, try new activities, or pick up an old one that you have forgotten.
Here are some suggestions of activities that parents CAN do with their children on this day that will have the most powerful impact on a child’s sensory and motor properties.
You don’t have to limit these suggestions to a National Day of Unplugging, so feel free to do them frequently.
You will be providing your kids with the ingredients they need to strengthen their bodies and minds.
1. Go out in nature!
Even if the weather is cold, take a walk, play in the snow, ice skate, or go sledding.
Do something physical but also talk about what you see and feel in the world, that is, the colors, textures, temperature, clouds, and animals.
2. Start a garden indoors or outdoors!
Dig, plant, hoe, spread dirt, and plant seeds.
Work with your hands and have your child get his or her hands dirty.
3. Cook together!
Especially focus on the gooey stuff, such as mixing, stirring, spreading, and pouring.
For older children, allow them to cut and chop with supervision.
4. Read together!
Tell each other stories.
Ask questions about what you are reading.
Ask your children to anticipate what they think will happen.
Ask them to make up a different ending.
Or simply tell stories to each other.
5. Play with manipulatives together!
Try various types but especially ones that require pushing and pulling.
Try pop-beads for younger hands and Zoobs for older hands.
Don’t tell your children what to make.
See what they come up with and then talk about it.
6. Make an obstacle course indoors or outdoors!
Use furniture, toys, and pillows, and then go over, under, through, and around objects.
Change directions and go the other way.
Then try crawling backwards.
Unplug and enjoy!!!!!
Be more active and sit less and you’ll improve your chances of preventing heart failure.
That’s the message of the first study to provide evidence that high levels of sedentary time, even among physically active men, places them at risk for heart failure.
“The evidence of the effects of physical activity on heart failure is developing.
Our study adds to this by examining the associations in a large racially and ethnically diverse population.
We provide even more evidence that moving more and sitting less can lead to better health,” says lead author Deborah Rohm Young, PhD, research scientist at the Kaiser Permanente Southern California Department of Research & Evaluation, Pasadena, CA.
Dr. Young and colleagues examined the electronic health records of nearly 83,000 men aged 45 years and older who were part of the California Men’s Health Study and had enrolled in Kaiser Permanente health plans in the Northern and Southern California regions.
The researchers published their results in the January 21, 2014 issue of the journal Circulation: Heart.
After monitoring these men for more than 10 years, they found that the risk of heart failure in those who reported high levels of sedentary time and low levels of physical activity was twice that in men who reported high physical activity and low sedentary time.
Although the researchers were not able to identify the types of exercise that the men did in the study, Dr. Young suggested that “brisk walking is a great form of physical activity.
It can be done almost anywhere, it does not require equipment, and most people of all ages can do it.”
She says that a brisk walk is “as if you’re in a hurry, and is defined as a 3- to 4-mile per hour pace or a 15- to 20-minute mile.”
To prevent heart disease, Dr. Young encourages men to meet the National Physical Activity Guideline—150 minutes per week of moderate intensity physical activity.
“We are still learning about the detrimental effects of high daily sedentary time,” she says.
“At this point, there is no consensus on how much sedentary time is too much.
Plus, our study only asked about sitting time outside of work.
But given the number of health benefits from being physically active, people should find ways to put physical activity into their lives and spend less time sitting.”
At Kaiser Permanente, clinicians have initiated an “Exercise Vital Sign” program in which all members are asked about their physical activity at every outpatient visit.
“The information is recorded in their electronic health record and is available for the health care providers when they see the patient.
It provides an opportunity for the provider to counsel the patient on physical activity levels,” Dr. Young says.
She suggests that primary care physicians ask their patients about their regular physical activity.
“When it’s insufficient, patients need to hear that regular physical activity is important for their health.
Physicians can be powerful advocates in helping to promote this message.”
Marriage is good for the health of some men’s bones, according to the first study to link marital history and quality of marriage to bone health.
Men who married when they were older than age 25 had greater bone strength than men who married when they were younger.
In addition, men in stable marriages or marriage-like relationships who had never previously divorced or separated had stronger bones than men whose previous marriages had failed.
Men in stable relationships also had better bone health than men who had never married.
“There is very little known about the influence of social factors, other than socioeconomic factors, on bone health,” said Carolyn Crandall, MD, Professor of Medicine in the Division of General Internal Medicine and Health Services Research at the David Geffen School of Medicine at the University of California at Los Angeles.
“Good health depends on good behaviors, such as maintaining a healthy diet and not smoking, but also on other social aspects of life, such as marital life stories and quality of relationships.”
The researchers published their results in the January 2014 issue of Osteoporosis International.
Marital History and Bone Mineral Density
Dr. Crandall and colleagues used data from 632 adult participants, about half of them men, in the Midlife in the United States Study to examine associations between marital history and bone mineral density.
They also took into consideration other factors that influence bone health, such as medications, health behaviors, and menopause.
The associations between marriage and bone health were evident in the spine but not the hip, possibly because of differences in bone composition, Dr. Crandall said.
She noted that the study did not include longitudinal assessments of bone density, and therefore the findings only suggest a correlation, not cause and effect.
The Stresses of Early Marriage
It’s possible that very early marriage may be detrimental to a man’s bone health because of the stresses of having to provide for a family.
“Men who marry before age 25 may be less educated and have more trouble making ends meet than men over age 25, who may have already been working for a few years.
So it may be that marriage is more stressful for younger men than those who marry later in life,” said Dr. Crandall.
She noted that “stressful environments are believed to activate several physiological systems, such as the sympathetic nervous system, inflammation, and the hypothalamic-pituitary-adrenal axis.
Although previous studies have not examined marital histories in relation to bone health, overactivation of those physiological systems is believed to be harmful to bone health.”
The next phase of research will examine the biological pathways that may connect bone health and marriage.
Healthy Bone Behaviors
“It’s premature to suggest doing more frequent or earlier bone density tests in men solely due to their being previously divorced, widowed, or separated, or solely due to their never having been married,” said Dr Crandall.
She suggests that men be extra vigilant about following current osteoporosis screening guidelines, and she encourages them to practice healthy bone behaviors — take in optimal amounts of calcium and vitamin D, do plenty of weight-bearing activity, such as walking, and avoid smoking as well as drinking excessive amounts of alcohol.
If you are overweight, you are at increased risk for catching the flu and other potentially serious respiratory diseases.
So say the results of a new study that adds more evidence that obesity alters the body’s immune system, leaving heavy people vulnerable to respiratory infections.
“Being sick — even if it is just a cold — is not fun, and reducing the frequency of respiratory infections is desirable for anyone.
Most obese patients are already well aware of the risk of diabetes and other chronic conditions associated with obesity, but they probably aren’t aware of the immunosuppression and increased risk of acute infections as well,” said Jeffrey Kwong, MD, from the Institute for Clinical Evaluative Sciences, Toronto, Ontario, Canada.
Earlier studies have shown that antibodies produced in response to flu shots plunge dramatically among obese people compared with those who have healthy weights.
The Heavier the Person, the Higher the Risk
Dr. Kwong and colleagues, including lead author Michael Campitelli, MPH, conducted a retrospective cohort study for a period of 13 years involving more than 100,000 persons in Ontario, Canada, who responded to population health surveys.
The researchers published their results in the January 2014 issue of the International Journal of Obesity.
They observed higher rates of outpatient visits to a physician’s office or emergency department for acute respiratory infections during the influenza season for those who were overweight and obese compared with normal weight people — even though the heavier people were more likely to be vaccinated.
The increased risk was highest among those who were the heaviest.
The rates were 20% higher in severely obese people who had a body mass index (BMI) of 35 kg/m2 or higher than in people of normal weight.
The researchers also saw lower but similar increased risks of respiratory infections among the obese people during seasons when flu was not circulating.
Increased Risk of Flu
“Obese people with a BMI of 30 or higher had more outpatient visits for acute respiratory infections during both influenza and non-influenza seasons,” said Dr. Kwong.
“This suggests that obesity not only increased the risk for influenza infection, but for other respiratory pathogens, likely both viral and bacterial.”
Deficits in the immune system can impair the response to respiratory pathogens and enhance susceptibility to infections.
“Both animal and human studies have noted immune function deficiencies among those who are obese,” Dr Kwong said.
Losing Weight Boosts the Immune System
In fact, losing weight may help boost the immune system for obese people.
“Studies of cell function in obese people have shown improvements in immune responsiveness following weight loss or dietary restriction,” Dr. Kwong said.
“For example, obese individuals showed increased T-cell responsiveness to mitogen following a weight reduction program.
Therefore, reducing weight in an obese person may help improve some of the obesity-related immune deficiencies, leading to a more robust response against respiratory pathogens.”
The bottom line is that “this represents yet another potential motivator for obese people to lose weight,” said Dr. Kwong.
