Blood pressure risk in overweight children

Blood pressure risk in overweight children
Sophia Antipolis, 15 October 2010: The European Society of Cardiology (ESC) welcomes the findings of a paper presented today at the American Heart Association's High Blood Pressure Research 2010 Scientific Sessions (HBPR 2010) held in Washington, DC, USA. The paper details research into the relationship between body mass index (BMI) and blood pressure in children. It concludes that an increase in BMI in already overweight children risks a far greater rise in blood pressure than would the same increase in BMI in normal-weight children.

Commenting on the paper, ESC spokesperson Professor Jos Ramn Gonzles-Juanatey from the Hospital Clinico Universitario Santiago in Spain, said, "This study is relevant because it emphasises the relationship between BMI and blood pressure in children. It is very important for everyone, particularly the general population, to understand the significant cardiovascular risk caused by childhood obesity, and the simple fact that weight reduction and exercise can have a major and positive impact." .

Co-author of the paper is Doctor Wanzhu Tu of the Regenstrief Institute in Indianapolis. The research team tracked blood pressure, height and weight measurements from over 1,000 children for a period up to 10 years, and compared BMI to national charts adjusted for age, sex and height. Children with BMIs above the 85 percent point are considered overweight. Below this level, BMI effects on blood pressure appear fairly linear, but for those above the 85 percent point and particularly above the 90 percent point the BMI effects are noticeably stronger.........

Obesity for children neglected by parents

Obesity for children neglected by parents
Strategies for decreasing a childs risk for obesity often focus on improving eating habits and maintaining a high level of physical activity. While this is one way to address the issue, another way to reduce the risk of childhood obesity could simply come down to positive parenting, as per a Temple University study reported in the recent issue of Child Abuse & Neglect.

This is the first study to show the association between neglect in childhood and childhood obesity. Prior studies looked at maltreatment in childhood and how it affected these individuals in adulthood, said Dr. Robert Whitaker, the studys lead author and a pediatrician and professor of public health at Temple University.

Examples of neglect include a parent not showing enough affection to the child due to preoccupation with his/her own problems, not taking a child to the doctor when he/she needed it, and leaving a child at home without the proper supervision.

Data was obtained from the Fragile Families and Child Wellbeing Study, a birth cohort study of 4,898 children born between 1998 and 2000 in 20 large U.S. cities. At age 3, 2,412 of these children had their height and weight measured, and mothers answered items on the Parent-Child Conflict Tactics Scales about three types of child maltreatment in the previous year: neglect (such as not providing proper supervision for the child), corporal punishment (such as spanking the child on the bottom with a bare hand) and psychological aggression (such as threatening to spank the child but not actually doing it).........

Why I Gave Up Desserts To Become a Better Entrepreneur

Why I Gave Up Desserts To Become a Better Entrepreneur
I haven't had dessert in eight months. It sounds crazy, I know, especially given that I'm not on a diet. I've been right around 170 lbs. for the last 10 years, with the exception of a brief period where a running injury forced me to take 6 weeks off (I gained 12 pounds). I don't need to lose weight, I am simply trying to become a better entrepreneur.

It all started when research showed that self-discipline matters more than IQ for success. I wondered if that was really true, so I analyzed my own life and I looked at how many often I goof off when I should be working. For instance, I sit down to write a software spec. It should take me an hour. But first I check my email. Someone sent me an interesting link, so I visit the link. Then from there I start poking around the web. After 10 minutes, I realize I haven't started on the spec, so I shut down my browser and start writing. Then someone IMs me. I reply. For the next 20 minutes, I write a sentence or two of the spec, then respond to IM, then write, then IM. I finally realize I'm being slow and I shut down instant messenger. Then I look at what I wrote and it doesn't flow well. Of course it doesn't, because every 60 seconds I was changing context. By now, I'm thirsty, so I go get something to drink. This keeps up for two hours, and at the end of it all I'm only halfway done with the spec. I spend 2 hours doing the same thing later that day. What should have taken one hour now ends up taking four altogether. I feel like I've worked hard. After all, I just spent 4 hours writing a spec.

Time deceives. When Peter Drucker consulted with organizations, he often made executives keep a log of their time. When it was analyzed at the end of several weeks, they were usually shocked at how they really spent their time vs. how they thought they spent it.

Time management in this day and age is much harder than it used to be. Our brains are primed to pay attention to people, to communications, to whatever is going on in the lives of others. Spending a quiet hour focused on a single topic is rare. I believed that if I could spend some quiet hours working, I would get more done. But removing myself from the constant connectedness was hard. Maybe I just needed more discipline. Maybe more discipline would make me successful.

Plato wrote that "the first and best victory is to conquer the self." Warren Buffett said something to the effect of "if you have discipline in the small things you will have discipline in the large things." I've read enough about the human brain to know that if certain actions are repeatedly taken, the brain becomes used to them and they become easier. I started to wonder if I could build my overall discipline by practicing more discipline in a small area of my life. I needed something that was difficult, but not in my face every day. I decided to give up desserts. For one year.

I wasn't cutting out sugar. The definition of a dessert was anything sweet that I would eat after lunch or dinner because I was craving it. The goal was to fight the impulse, more than anything else. No ice cream, cakes, cookies, candy, brownies, pies, or anything that would typically be considered a dessert.

When I initially announced this to friends and family, the responses ranged from "yeah right" to "that sounds like a miserable year." What I learned though, is that the desire for sweets is fleeting. You want them when you want them, but an hour later, or the next day, I don't sit around and think about how I really wished I had eaten those brownies. IMs and emails and phone calls and fun websites are the same way. I don't think there is a single message I've received in the last year that couldn't have waited an hour or two for a response. But when I don't finish a software spec, or a business plan, or returning emails, or whatever it is I wanted to get done but didn't - then I do feel bad the next day.

Eight months have passed, and I've had no desserts, and there have really only been 3 or 4 occasions that I seriously struggled and thought I should give up the stupid goal. What are the results? Well, I think the past 8 months have been the single most productive period in my entire life. I still miss deadlines, forget about things, and sometimes get distracted, but not nearly as often as I used to. In other words, I think it is actually working. My ability to buckle down and focus even when I don't feel like it has increased. In the same way that lifting weights makes a 50 pound box seem lighter the next time you have to carry it, focusing on a somewhat boring task for a few hours seems much easier than it was in the past.

A nice side benefit is that I've also felt much better in general. I've had more energy, I've slept better, and I've been sick less than normal. I haven't seen any negative mental side effects such as decreased creativity, or a diminished capacity to deal with multitasking situations (although I try to avoid these when possible).

So what can you learn from this experience, other than the fact that I am indeed a strange person? I think the two key points are that self-discipline really is a major component of success, and that self-discipline can be exercised, so that it becomes stronger.

The world is an interesting place, and we live in a time that is very exciting for entrepreneurs. There are lots of cool problems to solve. Don't let a lack of self-discipline interfere with your capacity to do great things.

Good news! The Fat Doctor is back

Good news!  The Fat Doctor is back
Good news.

The Fat Doctor is back.
"Famine-resistant doctor, pastor's wife, mom to one son, companion to two dogs, Diet Cokehead, TV junkie and frustrated writer approaches middle age with as little grace as possible......"
Always one of my favourite medical websites, and much missed. Kindness and compassion. No vitriol here.

Take a look at The Fat Doctor's recent posts:

Thirty eight reasons to lose weight
  • Live until 85 without debility.
  • Play with Son without getting winded.
  • Clothes from regular stores!
  • No cankles.
  • Swimsuits without embarrassment.
  • Want a tummy tuck eventually: Pannus be gone.
  • Avoid embarrassing Son when he is old enough to be teased.
  • Airplane seatbelts............................
  • Teensy Problem
    This morning, while peeing and contemplating all of the rest I plan to get this weekend, I glanced into the tub and saw a little mouse. It furiously pawed at the sleek wall of the tub trying to get out. Three hours later, it hadn't made any progress and had pooped. A lot. I admit, mice scare me.Lazy Eye
    As a doctor, I know I'm lucky. My child is able-bodied, intelligent and, perhaps most importantly, humorous. As a mother, I'm very concerned about his lazy eye. He'll be three in August, and I know we need to jump on this early.
    Welcome back, Fat Doctor.

    Darden Restaurants Profit Slides

    Darden Restaurants Profit Slides
    Darden Restaurants Inc., the world’s largest casual dining company, quarterly profit dip more than the Wall Street’s expectations as sales fell 2.2 percent at stores open at least 16 months in its Red Lobster chain.

    Darden, which owns and operates chains like Red Lobster and Olive Garden, posted a net loss of $55.1 million, or 39 cents a share, for the quarter ended May 27, as compare to a profit of $92.3 million, or 60 cents a share year earlier.

    Apart from the loss making chains, Darden’s Smokey Bones barbecue chain makes some profit, but still could not exceed the Wall Street expectation as it earns only 67 cents a share, whereas Wall Street analysts had expected 71 cents a share.

    Although Company’s total revenue mounts by 3.2 percent, to $1.46 billion, driven primarily by strong same-restaurant sales growth and new restaurant growth at Olive Garden, but it also ditched analysts’ forecast, which were on hefty $1.54 billion.

    Darden alleges that stiff rise in the oil prices were the main profit plunder for the dining company as it eloped customers from its sale. After striking by the losses Darden has planed to locked its 56 restaurants and is offering the remaining 73 outlets for sale due to languishing sales at Smokey Bones.

    At the time, the Orlando, Florida, company said it would take a pretax charge of $260 million related to the move.

    After loss making quarter’s result, Darden’s shares slide to $44.70 in after-hours trading after closing down 0.5 percent, or 23 cents, at $46.85 on the New York Stock Exc

    Obese Patients Fair Better

    Obese Patients Fair Better
    Scientists report that for patients hospitalized with acute heart failure, a higher body mass index (BMI) was linked to a substantially lower in-hospital mortality rate. For every 5-unit increase in body mass, the odds of risk-adjusted mortality fell 10 percent. The finding held when adjusted for age, sex, blood urea nitrogen, blood pressure, and additional prognostic factors.

    IMPACT: The finding offers more insight into an observed phenomenon in chronic heart failure called the 'obesity paradox.' This is the first study to document that this inverse relationship with BMI holds in the setting of acute hospitalization for heart failure. Further study is mandatory but the finding suggests that nutritional/metabolic support may have therapeutic benefit in specific patients hospitalized with heart failure.

    BACKGROUND: The study observed that by weight category, in-hospital mortality rate was 6.3 percent for underweight, 4.6 percent for healthy weight, 3.4 percent for overweight and 2.4 percent for obese patients. "The study suggests that overweight and obese patients may have a greater metabolic reserve to call upon during an acute heart failure episode, which may lessen in-hospital mortality risk," said Fonarow. Obesity is a known risk factor for developing heart disease and heart failure and every effort should be made to avoid it, but once heart failure has manifested, this paradox seems to occur. Scientists utilized data on over 100,000 acute heart failure patient episodes, taken from the Acute Decompensated Heart Failure National Registry (ADHERE). The study and ADHERE is funded by Scios, Inc. The authors have received research grants and served as consultants for Scios.........

    Obesity Epidemics

    Obesity Epidemics
    Obesity is a major health problem in the United States. Currently over half of the total population in the United States is said to be obese or overweight. Occurence rate of obesity continue to increase in males and females. Of all U.S. women twenty years and older, more than 64 million are overweight and about 34 million are will fall in to the catagory of obese women.

    Obesity is linked to marked health risks and higher death rates. Obese individuals are more prone to develop heart disease, type 2 diabetes, hypertension, stroke and a veriety of other medical conditions. It is very important that we all eat healhy food and maintain a program of exercise througout life. To lose weight and keep it off over time, try to make long-term changes in your eating and physical activity habits and active exercise.

    Measuring the exact amount of someone's body fat is not an easy task. The most accurate measures of body fat are weighing a person underwater or in a chamber that uses air displacement to measure body volume, or to use an X-ray test called Dual Energy X-ray Absorptiometry. Body fat mesaurements need not be so complicated. There are a number of simpler methods to estimate body fat. One is to measure the thickness of the layer of fat located below the skin in several parts of the body. Another involves sending a harmless amount of electric current through a person's body. Results from these methods, however, can be inaccurate if done by an inexperienced person or on someperson with extreme obesity.........

    Exercise For Older Adults

    Exercise For Older Adults
    For many older adults, a visit to the doctor is not complete without the bestowal of at least one prescription. What if, in addition to prescribing medications as necessary, physicians also prescribed exercise? Ann Yelmokas McDermott, PhD, a researcher in the Lipid Metabolism Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University, and Heather Mernitz, PhD, now of the Nutrition and Cancer Biology Laboratory at the USDA HNRCA, propose using the familiar concept of a prescription to help physicians incorporate exercise recommendations into their routine practice. In the journal American Family Physician, McDermott and Mernitz provide clinicians with explicit guidelines for giving their older patients effective "exercise prescriptions".

    Their motto for determining an exercise prescription is 'FITT-PRO':
    • Frequency
    • Intensity
    • Type
    • Time
    • Progression


    According to FITT-PRO principles, an exercise prescription must explicitly instruct the patient regarding what type of exercise to do, how often, how hard, and for how long. The exercises must also progress over time as the patient becomes more physically fit. McDermott and Mernitz caution that, as with medicine prescriptions, these exercise parameters must be personalized to suit each patient's health status and goals.........

    The Obesity Pandemic

    The Obesity Pandemic
    Obesity is a serious health problem in North America and several European countries. Recently over half of the total population living in the United States is believed to be having either overweigt or obesity. Rate of occurence of obesity continue to increase in both males and females. Among all American women twenty years and older, about 64 million can be considered as overweight and more than 34 million could be considered as obese.

    Excessive weight is linked to significant health hazards and increase death rates. Overweight individuals are more suseptible to suffer from coronory artary disease, diabetes, hypertension, cerebrovascular events and a veriety of other medical conditions. It is imperative that we all eat healhy food and routinely maintain a program of physical activity througout our life. To control weight and keep it off over time, try making long-term modifications in your dietery and physical activity habits.

    Estimating the exact amount of a person's body fat level is not easy. Most accurate ways to measure the amount of body fat include weighing a person underwater or inside a chamber that uses the principle of air displacement to estimate body volume, or to use an X-ray technique called DEXA. Mesaurements of body fat content need not be so complex. There are simpler methods available to estimate fat content of the body. One such method is to measure the thickness of the fat layer just under the skin in various parts of the body. Another method involves passing a small amount of electricity through a person's body to measure conductivity. Results obtained from these methods, can however be, less than accurate particularly if done by an inexperienced person or on someone with high level of obesity.........

    Botox Injections May Improve Facial-wound Healing

    Botox Injections May Improve Facial-wound Healing
    Botulinum toxin, the same Botox used to treat facial wrinkles, helps facial wounds heal with less scarring, as per results of a study reported in the recent issue of Mayo Clinic Proceedings.

    David Sherris, M.D., professor and chair of the Department of Otolaryngology at the University at Buffalo is senior author on the research.

    "This study is the first blinded trial demonstrating that injecting Botox (the trademark name for botulinum toxin) when we close a facial wound results in less visible scars," said Sherris, an ear, nose and throat specialist who came to UB from the Mayo Clinic in 2004.

    "This study is the culmination of work that Dr. Holger Gassner and I started at Mayo Clinic about seven years ago. The reason this works is because wide scars are the result of the local muscles pulling the wound apart during the healing phase," he said. "Botulinum toxin temporarily weakens the surrounding muscles, thereby lessening the pull on the wound during the acute healing phase of the first 2-4 months".

    The trial involved 31 patients who had sustained wounds to the forehead or were having elective surgery to remove skin cancers of the forehead. This area was chosen because it is especially susceptible to scarring, and because using Botox in this area has been shown to be safe and effective.........

    Why Do Statistics About Overweight And Obesity Differ?

    Why Do Statistics About Overweight And Obesity Differ?
    The definitions or measurement characteristics for overweight and obesity have varied over time, from study to study, and from one part of the world to another. The varied definitions affect prevalence statistics and make it difficult to compare data from different studies. Prevalence refers to the total number of existing cases of a disease or condition in a given population at a given time. Some overweight- and obesity-related prevalence rates are presented as crude or unadjusted estimates, while others are age-adjusted estimates. Unadjusted prevalence estimates are used to present cross-sectional data for population groups at a given point or time period. For age-adjusted rates, statistical procedures are used to remove the effect of age differences in populations that are being compared over different time periods. Unadjusted estimates and age-adjusted estimates will yield slightly different values.

    Previous studies in the United States have used the 1959 or the 1983 Metropolitan Life Insurance leads tables of desirable weight-for-height as the reference for overweight.[3] More recently, many Government agencies and scientific health organizations have estimated overweight using data from a series of cross-sectional surveys called the National Health Examination Surveys (NHES) and the National Health and Nutrition Examination Surveys (NHANES). The National Center for Health Statistics (NCHS) of the Centers for Disease Control and Prevention (CDC) conducted these surveys. Each had three cycles: NHES I, II, and III spanned the period from 1960 to 1970, and NHANES I, II, and III were conducted in the 1970's, 1980's, and early 1990's. Since 1999, NHANES has become a continuous survey.........

    Is It Safe To Swim After Eating?

    Is It Safe To Swim After Eating?
    New research suggests one reason vegetables may be so good for us - a study in mice found that a mixture of five common vegetables reduced hardening of the arteries by 38 percent compared to animals eating a non-vegetable diet. Conducted by Wake Forest University School of Medicine, the research is published in the current issue of the Journal of Nutrition.

    "While everyone knows that eating more vegetables is supposed to be good for you, no one had shown before that it can actually inhibit the development of atherosclerosis," said Michael Adams, D.V.M., lead researcher. "This suggests how a diet high in vegetables may help prevent heart attacks and strokes".

    The study used specially bred mice that rapidly develop atherosclerosis, the formation on blood vessel walls of fatty plaques that eventually protrude into the vessel's opening and can reduce blood flow. The mice have elevated low-density lipoprotein ( LDL), or "bad" cholesterol, which is also a risk factor for atherosclerosis in humans.

    Half of the mice in the study were fed a vegetable-free diet and half got 30 percent of their calories from a mixture of freeze-dried broccoli, green beans, corn, peas and carrots. These five vegetables are among the top-10 vegetables in the United States based on frequency of consumption.........

    Physical Activity Key To Weight Control

    Physical Activity Key To Weight Control
    You know that physical activity is good for you. So what is stopping you from getting out there and getting at it? Maybe you believe that working out is boring, joining a gym is costly, or doing one more thing during your busy day is impossible. Physical activity can be part of your daily life. This booklet can help you get moving by offering ideas to beat your roadblocks to getting active.

    You may know that regular physical activity can help you control your weight. But do you know why? Physical activity burns calories. When you burn more calories than you eat each day, you will take off pounds. You can also avoid gaining weight by balancing the number of calories you burn with the number of calories you eat.

    Regular physical activity may also help prevent or delay the onset of chronic diseases like type 2 diabetes, heart disease, high blood pressure, stroke, and colon cancer. If you have one of these health problems, physical activity may improve your condition.* Regular physical activity may also increase your energy and boost your mood.........

    Diet Study Shouldn't Be Seen as Eat-anything Permission Slip

    Diet Study Shouldn't Be Seen as Eat-anything Permission Slip
    It was baffling, frustrating -- yet also, in a way, secretly gratifying. Last week, the largest study to follow low-fat dieters concluded there weren't any definite protective benefits.

    To the surprise of a number of scientists, the study didn't show that a lower-fat diet leads to less incidence of breast cancer, colon cancer or heart disease. In fact, one way to sum up this study is:.

    Sorry. Bad things still happen even to good dieters.

    The disappointing results of this study, which tracked nearly 50,000 women, gave all of us an excuse to duck into the nearest doughnut shop, ranting. Or at least pondering a consoling thought: Have the nation's nutritionists gone nuts? They've been exhorting us for years, after all, to eat less fat. Maybe their brains turned orange long ago from eating too a number of carrots.

    After a brief, cathartic interval of invective, though, dieters have to regroup and ask themselves: What next? Unfortunately, even though a number of Americans will carry away a definitive impression from this study, the results aren't as definite as people think.........

    Weight Loss Diets

    Weight Loss Diets
    The main goal of these diets will always be to lose weight. Weight loss diets must also be designed to take into account individual body needs for healthy nutrition. At the same time, the role of physical exercise must not be overlooked.

    There is no such thing as a "best diet" or a "miracle diet", a universal diet plan that works for everybody. Diet programs should be adapted to personal needs, while taking into account specific, individual parameters.

    People with weight problems should begin by analysing their condition. Only after that should they decide on a weight loss objective. To set realistic goals, the dieter-to-be should be aware of some facts about losing weight and weight loss diets.
    • Weight-loss and maintenance of the body weight within normal limits are essential for your general state of health.
    • Learn to analyse the parameters of your body. Try to keep them under control.
    • Do not overlook health-linked nutritional aspects in the process of losing weight.
    • It is important to prepare yourself mentally for healthy weight-loss. This involves:
      • Not expecting spectacular results in a very short period of time. Normally they do not happen. If they do it will not be on a long-term basis. Patience, at least at meal-times, should become one of your basic virtues.

    Obesity War

    Obesity War
    The obesity wars continue. They are interesting. I read the recent JAMA article (April 20 issue) and as far as I can see it is well done (eventhough I am not an expert in this particular area, I am a chronic disease epidemiologist). What the data seem to show is that the prior CDC definition of optimal weight, as measured by Body Mass Index and using risk of death as an outcome (rather than morbidity) should be redefined, moving slightly upward. The data still reveal considerable increased mortality (112,000 excess deaths) for the truly overweight (BMIs above 30).

    So why is this interesting? Because of the smarmy politics. The Right wing didn't complain much about highlighting obesity when it was conceived of as a personal failing, a lack of will-power and discipline. Obese people eat too much. But then the public health started to call attention to the structural determinants of excess caloric intake (advertising, mass marketing of unhealthy foods, easy access and marketing to school children, etc.). When the tort system became involved (obesity lawsuits against fast food chains) the Right saw an opportunity and turned against the obesity meme. Public health never had its act together because the notion that there is some personal accountability involved in excess weight is a widely shared cultural notion (I am taking no position as to its truth or falsity here). In addition there were other interests involved. The anti-smoking portion of public health was dismayed to have cigarettes displaced as the number one killer and fiercely attacked the first (and faulty) CDC study. I think it is fair to say, too, that there was more than a little hype about the dangers of obesity. This made the "obesity epidemic" a prime (and easy) target for the Right.........
