BMI vs. BAI

To use BMI or not to use BMI, that is the question!

For hundreds of years, people have been using a tool called, Body Mass Index (BMI) to measure body fat in adults.  However, it has known limitations as a useful measurement of accuracy.


A new tool could soon be replacing the traditional BMI to measure healthy body size. A recent study in Obesity (Obesity 19, 1083-1089, May 2011) found that using Body Adiposity Index (BAI) was a more precise measurement than BMI.



BAI is calculated by using height and hip circumference vs. BMI which is calculated by dividing weight by height. The problem with BMI, is that it does not distinguish between a large body size due to muscle mass or due to obesity. For years many professional athletes have had “unhealthy” BMIs, however, they are quite healthy and in top physical condition.


Another reason to use BAI, by measuring hip circumference and height, the new Body Adiposity Index (BAI) can be used to reflect percentage of body fat for adult men and women of differing ethnicities, without numerical correction or assessment of weight. BMI is measured differently for men and women. And the BAI estimates the percentage of adipose (or fat) directly. 


So, the next time you are at the doctor's office, as your healthcare provider to measure yoru BAI. This may be a better tool in helping us combat the growing obesity epidemic in the USA and the world over!

Impulsivity strongest predictor of obesity

July 18, 2011 - Article from the American Psychology Association

Personality Plays Role in Body Weight, According to Study



WASHINGTON—People with personality traits of high neuroticism and low conscientiousness are likely to go through cycles of gaining and losing weight throughout their lives, according to an examination of 50 years of data in a study published by the American Psychological Association.

Impulsivity was the strongest predictor of who would be overweight, the researchers found. Study participants who scored in the top 10 percent on impulsivity weighed an average of 22 lbs. more than those in the bottom 10 percent, according to the study.

“Individuals with this constellation of traits tend to give in to temptation and lack the discipline to stay on track amid difficulties or frustration,” the researchers wrote. “To maintain a healthy weight, it is typically necessary to have a healthy diet and a sustained program of physical activity, both of which require commitment and restraint. Such control may be difficult for highly impulsive individuals.”

The researchers, from the National Institute on Aging, looked at data from a longitudinal study of 1,988 people to determine how personality traits are associated with weight and body mass index. Their conclusions were published online in the APA’s Journal of Personality and Social Psychology.

“To the best of our knowledge, we are the first to examine whether personality is associated with fluctuations in weight over time,” they wrote. “Interestingly, our pattern of associations fits nicely with the characteristics of these traits.”


Participants were drawn from the Baltimore Longitudinal Study of Aging, an ongoing multidisciplinary study of normal aging administered by the National Institute on Aging. Subjects were generally healthy and highly educated, with an average of 16.53 years of education. The sample was 71 percent white, 22 percent black, 7 percent other ethnicity; 50 percent were women. All were assessed on what’s known as the “Big Five” personality traits – openness, conscientiousness, extraversion, agreeableness and neuroticism – as well as on 30 subcategories of these personality traits. Subjects were weighed and measured over time. This resulted in a total of 14,531 assessments across the 50 years of the study.

Although weight tends to increase gradually as people age, the researchers, led by Angelina R. Sutin, PhD, found greater weight gain among impulsive people; those who enjoy taking risks; and those who are antagonistic – especially those who are cynical, competitive and aggressive.

“Previous research has found that impulsive individuals are prone to binge eating and alcohol consumption,” Sutin said. “These behavioral patterns may contribute to weight gain over time.”

Among their other findings: Conscientious participants tended to be leaner and weight did not contribute to changes in personality across adulthood.


“The pathway from personality traits to weight gain is complex and probably includes physiological mechanisms, in addition to behavioral ones,” Sutin said. “We hope that by more clearly identifying the association between personality and obesity, more tailored treatments will be developed. For example, lifestyle and exercise interventions that are done in a group setting may be more effective for extroverts than for introverts.”

Post Traumatic Growth

Can feeling depressed actually make you healthier?

According to a 2008 CDC report, 1 in 20 Americans are reported to be depressed.  80% of them report some level of functional impairment because of their illness, 27% report it being extremely difficult to work, to get things done at home, or get along with others due to these depressive symptoms.

In 2000, almost 2/3 of the estimated $83 billion dollars which depression cost the USA, resulted in lowered productivity and workplace absenteeism.

In the USA, the prescription use of anti-depressants has doubled in the last ten years. About 10% of the adult population in the USA takes anti-depressants.  Yet, the vast majority of people take pills and do not seek the proper treatment that they may need to overcome the depression.

Now, please do not misunderstand me, I am not opposed to people taking anti-depressants. I do believe anti-depressants certainly have their place in treatment for some people. What I am opposed to, is the over-use, over-prescribing, and over-dependence on using anti-depressants while not actually facing the real issues. Anti-depressants are great at masking your symptoms, however, they do not cure you of the problem. 

I think one of the reasons why the use of medication is more popular over therapeutic treatments for depression/anxiety come down to the common attitude among Americans’: taking a pill is the easiest way to ‘cure’ what ails me.

American’s don’t like to exercise – take a pill. They don't like to eat right to get the necessary nutrients in a day – take a pill. They don’t want to cry, be sad, face their fears – take a pill.  We are even told that it is the best method for helping us - we are bombarded by anti-depressant, anti-anxiety ads on TV – so it is too easy to go into your doctor’s office, ask for them by name, and your doctor agrees to prescribe them, because they don’t have time to listen to your troubles (average office visit with a doctor 3-7 minutes).

 Another reason why it is so easy to get anti-depressants vs. seeking Cognitive Behavioral Therapy or other therapeutic treatments, is because insurance companies have made it easier to get anti-depressants and hard to get CBT treatment. We know that it takes at least 10-11 CBT sessions to have a true break-through with behavioral change. Just because someone seeks out traditional or alternative psychotherapy treatments, doesn’t mean they are truly ready to change or begin their own personal work towards change right away. So, it can take 10-11 sessions (if not more), before that “aha moment” strikes and the real change begins. Well, insurance companies think 6 sessions is more than reasonable and patients are not always keen to pay the $90-$200/hour sessions with their therapist.

Also, people feel that if they are not better after 6 sessions, then therapy must not be working. This is a complete misinterpretation of therapeutic expectations. Therapy doesn’t have to take years, but it may take longer than 6 session to see a real improvement.

There is a silver lining to depression, sadness, or the tragic events which can happen to us throughout our life. We’ve all heard of Post-Traumatic Stress Disorder (PTSD is a mental health condition that's triggered by a terrifying event. Symptoms may include flashbacks, nightmares and severe anxiety, as well as uncontrollable thoughts about the event. Definition from the Mayo Clinic Website), but have you ever heard of Post Traumatic Growth?

Post-traumatic Growth- is a positive change experienced as a result of the struggle with a major life crisis or a traumatic event. The idea that human beings can be changed by their encounters with life challenges, sometimes in radically positive ways, is not new.  This concept appears in many ancient spiritual and religious traditions, literature, and philosophy.  What is reasonably new is the systematic study of this phenomenon by psychologists, social workers, counselors, and scholars in other traditions of clinical practice and scientific investigation.

Rich Tedeschi, a professor of psychology at the University of North Carolina in Charlotte who coined the term "post-traumatic growth,” studies people who have endured extreme events such as:  combat, violent crime, natural disasters or sudden serious illness.  His research has shown that most people feel dazed and anxious in the immediate aftermath of “the event.”

They are preoccupied with the negative and with the belief that their lives have been completely negatively altered or devastated. A few are haunted (sometimes for a long period of time) afterwards by memories; they can have trouble with sleep, and even experience similar symptoms of post-traumatic stress disorder. But Tedeschi and other researchers have found that for many people—perhaps even the majority of the population—life ultimately becomes richer and more gratifying.

Posttraumatic growth tends to occur in 5 general areas:

1)      Sometimes people who must face major life crises develop a sense that new opportunities have emerged from the struggle,

a)      opening up possibilities that were not present before.

2)      A change in relationships with others.

a)      Some people experience closer relationships with some specific people, and they can also experience an increased sense of connection to others who suffer.

3)      An increased sense of one’s own strength – “if I lived through that, I can face anything”.

4)      A greater appreciation for life in general.

5)      The spiritual or religious domain is affected

a)       Some individuals experience a deepening of their spiritual lives, however, this deepening can also involve a significant change in one’s belief system.


So, life doesn’t have to be full of painful, tragic memories. How we choose to remember the event or examine our past negative events can certainly influence our future trajectory in life. Now, it’s not easy – it takes work on your part to overcome these negative feelings or memories, but there is hope. You can overcome!

In fact, depression may be our body’s natural way of telling us to stop and focus on what is troubling us, so we can move beyond it. From an evolutionary perspective – depression may lead to better mental health.  Even Aristotle wrote about this theory during his time (384 BC – 322 BC). Today there are many proponents of psychology who feel that depression should not be a “disorder” based on this evolutionary psychology perspective of humans and their emotions.  Dr. Paul Andrews (PhD) of Virginia Commonwealth University and Dr. J. Anderson Thomson (MD) of Student Health Services and Institute of Law and Psychiatry at the University of Virginia believe that depression can actually facilitate the kind of rumination one needs to help overcome tragedy. 

Most depressed individuals say they have a hard time concentrating and paying attention because they are focused solely on the problem.  Thomson feels that this perception isn’t entirely accurate. He says, “the real problem is that they can think about only one thing – the issue that’s troubling them- and that gets in the way of trying to concentrate on work or anything else.”  He references studies that show sadness can actually promote analytical thinking which may allow one to break down a complex problem into a smaller more manageable issue to solve.

There isn’t one way to overcome depression. There isn’t one sure fire “cure” – whatever your beliefs and philosophies about how to best treat your depression just remember – seek help. Whether it is from a professional or a loved one/friend/family member, depression makes us want to retreat inwards and become solitary. Yet, seeking social situations is also a necessary part to overcoming and beginning the long journey to recovery.

Information on the American Psychology Association’s  Website:
Depression is more than just sadness. People with depression may experience a lack of interest and pleasure in daily activities, significant weight loss or gain, insomnia or excessive sleeping, lack of energy, inability to concentrate, feelings of worthlessness or excessive guilt and recurrent thoughts of death or suicide.
Depression is the most common mental disorder. Fortunately, depression is treatable. A combination of therapy and antidepressant medication can help ensure recovery.

What You Can Do
Seek the right kind of social support - Social isolation increases the risk of depression. But it turns out that spending too much time discussing problems with friends could actually increase depression as well.
Exercise Helps Keep Your Psyche Fit - Exercise is an effective, cost-effective treatment for depression and may help in the treatment of other mental disorders.

Getting Help
Depression is a real illness and carries with it a high cost in terms of relationship problems, family suffering, and lost work productivity. Yet, depression is a highly treatable illness, with psychotherapy, coping and cognitive-behavioral techniques, and medication.

What You Can Do
Exercise: You don't have to knock yourself out to feel good - Even a little exercise can reduce depression and boost your energy levels.
Turning Lemons into Lemonade: Hardiness Helps People Turn Stressful Circumstances into Opportunities - Research shows hardiness is the key to the resiliency for not only surviving, but also thriving, under stress. Hardiness enhances performance, leadership, conduct, stamina, mood and both physical and mental health.
The happiness diet - Sonja Lyubomirsky argues that limiting overthinking can improve our emotional well-being.

July is Blueberry Month

Blueberries

July is National Blueberry Month and just to wet your whistle to this superfruit, here is some information and great receipes for this amazing food!



According to the US Highbush Blueberry Council website: (http://www.blueberrycouncil.org/health-benefits-of-blueberries/blueberry-nutrition/):  Blueberries are just 80 calories per cup and virtually no fat, blueberries offer many noteworthy nutritional benefits. Here’s the skinny on blueberry nutrition:

Blueberries are packed with vitamin C.

In just one serving, you can get 14 mg of Vitamin C – almost 25 percent of your daily requirement. Vitamin C aids the formation of collagen and helps maintain healthy gums and capillaries. It also promotes iron absorption and a healthy immune system.

Blueberries are dynamos of dietary fiber.

Research has shown that most of us don’t get enough fiber in our diets. Eating foods high in fiber will help keep you regular, your heart healthy and your cholesterol in check. A handful of blueberries can help you meet your daily fiber requirement. What a tasty way to eliminate this worry from your day!

Blueberries are an excellent source of manganese.

Manganese plays an important role in bone development and in converting the proteins, carbohydrates and fats in food into to energy – a perfect job for blueberries.

Blueberries are leaders in antioxidant activity.

According to the U.S. Department of Agriculture (USDA), blueberries are near the top when it comes to antioxidant activity per serving (ORAC values). Their capacity is impressive – Antioxidants work to neutralize free radicals — unstable molecules linked to the development of cancer, cardiovascular disease and other age-related conditions such as Alzheimer’s. Substances in blueberries called polyphenols, specifically the anthocyanins that give the fruit its blue hue, are the major contributors to antioxidant antioxidant activity.

Does Your Doctor Make You Feel Fat?


The article below really intrigued me. I’ve always been a big believer in being your own health advocate. Doctor’s DO NOT know everything. They are humans and they too can make mistakes.  But what are you to do if your doctor discriminates against you because of your lifestyle and therefore misses a very important diagnosis?
We still need to be our own health advocates – it’s your life and your health – but we also need to still have trust in our healthcare providers.  We need to be able to confront our healthcare providers we feel like they are not giving us the best quality of care because of being overweight.
I personally don’t like smoking and I get very irritated with smokers. But, as a healthcare provider – I wouldn’t make any preconceived notions about one of my client’s just because they smoked. Sure, it is always better from a health perspective if they quit – but is it my place and my role to tell them to quit? NO! Unless, the reason why they are coming to me is for Smoking Cessation counseling – then of course – but otherwise it truly is none of my business and it certainly should not affect the relationship and quality of care that I will provide to the individual.
Check out the article below and let me know what you think. Has anything like this ever happened to you, friend or a family member? I know it has happened to me personally – actually I wasn’t “40, fat or fertile” to meet a requirement for an illness. Turns out I lived in pain and suffered for a year – before an Emergency Room Doctor finally listened to be – just before things got really bad.

Article from Prevention Magazine July 2011
by Harriet Brown


It's not your imagination. More than half of physicians admit they think less of their overweight patients. Here's how to make sure you get the health care - and respect - you deserve.

When Anna Guest-Jelley - 26 years old at the time - badly twisted her ankle, the Nashville native went to see her doctor. "Your ankle's probably swollen”, she said, “because you’re carrying extra weight.”
            Guest-Jelley, a yoga teacher, went along with her diagnosis. When the doctor reported that Guest-Jelley’s x-ray didn’t show any fractures, she returned home with instructions to ice her foot – and an all-too-familiar feeling of humiliation at the physician’s focus on her size. “Almost every time I’ve ever gone to a doctor’s appointment, I’ve experienced some level of shaming because of my weight,” she says.
            Her experience is shockingly common. Weight stigma is on the rise in America, according to the Rudd Center for Food Policy and Obesity at Yale University, and, ironically, nowhere is it more deeply rooted than among health care providers. Multiple studies have found that doctors, med students, nurses, dietitians, and other health care professionals routinely stereotype their heavy patients. In landmark 2003 research from the University of Pennsylvania, for instance, more than half of the 620 primary-care doctors surveyed characterized their obsess patients as “awkward,” “unattractive,” “ugly,” and “noncompliant” – the latter meaning that they wouldn’t follow recommendations. More than one-third of the physicians regarded obsess individuals as “weak willed,” “sloppy” and “lazy.”
            And it’s women who bear the brunt of this characterization – even when they’re not obese. Doctors’ weight prejudices start when a female patient is as little as 13 pounds overweight – meaning her body mass index would likely be around 27 – found a 2007 study from Yale University. (BMI is a measurement that uses a ration of height to weight to categorize people as being of normal weight [18.5 to 24.9], overweight [25 to 29.9], or obese [30+],) “For men, the bias doesn’t kick in until around a BMI of thirty-five, approximately 75 pounds overweight,” says Rebecca Puhl, PhD, director of Research and Weight Initiatives at the Rudd Center. “That’s a definite gender difference.”
            This bias can have a dramatic effect on women’s health, resulting in incorrect assessments of patients’ condition and questionable recommendations. It’s impossible to know today whether Guest-Jelley’s doctor, presuming that her patient’s BMI (which was then 38.6) was responsible for her ankle pain, did not read the x-ray as carefully as she might have. But after a few weeks of icing her ankle, Guest-Jelley returned to the doctor because her condition was getting worse. Once more, the doctor focused on the scale. “She told me about how her friend had gone to Weight Watchers and had lost all this weight,” remembers Guest-Jelley. “And I said to her, I’ve been on Weight Watcher’s 5 times.”
            At Guest-Jelley’s request, the doctor reluctantly referred her to an orthopedic specialist – who took another x-ray and told her that her ankle had been broken all along. Since the fracture hadn’t been recognized and properly treated for many weeks, Guest-Jelley’s ankle never properly healed.
********
            “I hear so many stories of doctors making assumptions about patients’ health and lifestyles based on their appearance,” says Arya Sharma, MD, PhD, chair of obesity research management at the University of Alberta. “One of the key factors underlying this stereotyping Is the notion that nobody would be obese if they were eating healthy and exercising,” Dr. Sharma says. “But for every obese person I see who doesn’t exercise two hours a day or who’s drinking gallons of soda pop, I’ll treat then thin people doing exactly the same thing.”
            Many women find that no matter what their symptoms are, their physicians blame their weight. Take Parker Ross, 21, an avid walker and bicyclist who’s had asthma since childhood. Last year Ross, who weighs about 300 pounds, lost her health insurance and went without medication for a year. When her asthma got so bad that she couldn’t’ walk around the block, she saw a doctor. “I found myself being told that ‘obviously’ my weight was the big problem, and I should try to get some exercise,” says Ross.   Although, she explained that she couldn’t breathe well enough to exercise, the doctor refused to prescribe new asthma medication for and instead wrote a prescription for Zoloft – surmising that she must be too depressed to focus on weight loss or exercise.  “Everything I was trying to say to her was being just completely erased by her perception of my fat,” says Ross. “Who I was simply got erased.”  Fortunately, Ross has since found another doctor to treat her asthma.
            Mary Tretola, 52, a CPA and a mother of two who lives in Seaford, NY, had a similar experience with her doctor. Since her mid-20s, she’s had a circulation condition that makes her legs swell.  “Maybe being overweight does strain my legs, but even when I weighed sixty pounds less than I do now, I still had this problem,” points out Tretola.
            In some cases, overweight women may be refused medical treatment altogether. Liv Linhares, now a 350-pound 35-year old social worker in Portland, OR, vividly remembers going to her student health center in college for a routine pelvic exam. At the end, the doctor said, “because of your obesity, I can’t accurately feel your ovaries, so I can’t tell if there are any concerns.” He asked the then-20-year-old Linhares to sign a waiver saying that if she did turn out to have cancer, the health center wasn’t responsible.  Linhares was mortified – and terror stricken. “I thought, Oh my God, I could have cancer and not know it!” she remembers. “He didn’t ask me anything about my life, how I ate, whether I exercised, if I smoked or had unprotected sex – no other questions about my overall health.” Too unsure of herself to speak up, she simply never returned to her health center.
            This reluctance to seek medical care is an understandable response, but it can be deadly. “Obese women go less frequently for Pap tests than their thinner counterparts because of the prejudice they run into,” says Joseph Majdan, MD, a cardiologist at Jefferson Medical College who has written about how he himself was stigmatized by fellow doctors before he lost 100 pounds. Research shows that obese women typically get fewer screenings for breast and colorectal cancer too. This finding is especially chilling given the fact that women with BMIs of 30+ are more likely to die from certain cancers – endometrial, esophageal, and kidney, among them – according to a study of more than 1 million women in the United Kingdom.
********
            Doctors, of course, are expected to rise above social prejudices and treat all their patients with compassion. But physicians’ behavior often mirrors the broader culture’s attitudes. “As a society, we value thinness and hard work, so we equate being fat with being lazy,” says Mary Margaret Huizinga, MD, an assistant professor of medicine at Johns Hopkins University. Although most doctors say they show consideration for everyone they treat, no matter what, her research has found that physicians’ respect clearly diminishes as a patient’s BMI goes up.  “Till society changes, the medical profession won’t either,” she says.
            Many doctors argue that, overall, they do a good job of attending to all their patients equally. Indeed, a 2010 University of Pennsylvania study established that despite the clear weight bias among doctors, they recommended the same treatments for a specific list of conditions – including diabetes and certain cancer screenings – regardless of patient’s size or BMI. However, the study didn’t consider other complaints associated with obesity (such as joint pain and shortness of breath), and it looked mostly at older men, who are less likely to experience weight bias.
            What’s more, the study didn’t examine whether there was any difference in the way physicians communicated medical recommendations to their patients of different weights – and that may be just as key. “One of the most important parts of medical relationship is the patient feeling able to ask questions and being comfortable with the doctor’s advice,” notes Dr. Huizinga.
********
            Treating obesity, however, is uniquely challenging. 95% of people who lose weight gain it back within 3-5 years – which may leave physicians feeling frustrated and helpless and perhaps inclined to blame patients. “When a person has cancer that recurs, the physician is so empathetic,” Dr. Sharma says. “But when a person regains weight, the response is disgust. And that’s morally and professionally abhorrent.”
            When doctors take courses that emphasize “uncontrollable” causes of obesity, such as genetics or certain medications, their weight bias diminishes. But, although medical school curricula are expanding, most physicians who are practicing today received little training on weight issues.
            Patient advocacy groups such as the Association for Size Diversity and Health and the National Association to Advance Fat Acceptance argue that since obesity has been so stigmatized and is so difficult to treat, doctors should be taught to focus less on weight itself and more on other indicators of health, pointing out that even overweight people can be otherwise healthy.  They cite studies like the one published in the Journal of the American Medical Association in 2005 that found that people considered overweight (with BMIs 25-29.9) actually had lower mortality rates than those viewed as being of normal weight. And some advocates also feel that whether weight is mentioned at all should be up to the patient.
            But there are also doctors who are strongly committed to avoiding the pitfalls of obesity prejudice – while still addressing weight head-on. “The first thing that comes out of your mouth when you meet a patient can’t be ‘You’re obese,’” says Juan Rivera, MD, a preventative cardiologist and as assistant professor at Miami School of Medicine. “You have to wait for the right moment, and be prepared to work together for a long time. Fighting obesity is a marathon, not a sprint.” Above all, Dr. Rivera says, it takes sensitive, honest communication.
            For women who feel that their doctors treat them with less dignity due to their weight, experts, including Dr. Rivera, advise telling the physicians, calmly, what they perceive as biased behavior and how they feel about it. “Ultimately, both parties will benefit,” says Dr. Rivera.  “And if your physician doesn’t take the criticism well, it might be good time to switch doctors.”
            Finding a new provider can make a world of difference. After Tretola’s doctor dismissed her swollen legs, she scheduled a physical with a new practitioner. “The doctor asked if I wanted to be weighed, and I said, ‘I’d prefer not to today,’” Tretola reports. “That was fine with him. We did talk about weight, but he was very welcoming, not judgmental, and he discussed problems – such as my high cholesterol – without blaming my weight.
            “It was so refreshing.”
