Obesity in adults means having too much body fat. Overweight means weighing too much. The balance between calories-in and calories-out differs for each person. Obesity occurs over time when a person eats more calories than they use. Factors that might tip the balance include genetic makeup, overeating, eating high-fat foods, and not being physically active. Being obese increases a person's risk of diabetes, heart disease, stroke, arthritis, and some cancers. If someone is obese, losing 5 to 10 percent of the weight can delay or prevent some of these diseases.
Dr. Chrostoph Correll, MD, and associates observed 272
children aged 4 to 19 taking atypical antipsychotic medication for the first
time. Drugs/Medications included olanzapine (Zyprexa), quetiapine (Seroquel),
risperidone (Risperadol) and aripiprazole (Abilify)—drugs sometimes used to
treat children with autism, schizophrenia or bipolar disorder.
Children’s weights were monitored over a 12-week period.
During the last two weeks of the study, nearly all experienced significant
weight gain. Average gain was as follows: 18.7 pounds with onanzapine, 13.7
pounds with quetiapine, 11.7 pounds with risperidone, and 9.7 pounds with
aripiprazole. Children in the control group gained less than half a pound (.44
pounds) on average.
“(E)ffects such as age-inappropriate weight gain, obesity,
hypertension, and lipid and glucose abnormalities are particularly problematic
during development because they predict adult obesity, metabolic syndrome,
cardiovascular morbidity, and malignancy,” authors of the study write.
Doctors were so concerned over weight gain in children
taking onanzapine that they stopped treatment before the study was completed.
“Each antipsychotic was associated with significantly increased fat mass and
waist circumference,” authors write. “Altogether, 10 percent to 36 percent of
patients transitioned to overweight or obese status within 11 weeks.”
As more children—some younger than 5-years-old—are diagnosed
with bipolar and “disruptive behavior” disorders (such as ADHD), there is
also a rise in atypical antipsychotic prescriptions. These medications are
generally effective for children with autism and schizophrenia, but they may
not be the best treatment for other conditions.
The authors suggest seeking alternative treatments. They
write that, in view of the negative health outcomes, the benefits of using
these medications “must be balanced against their cardiometabolic risks”, and
say the results suggest including in prescription guidelines closer monitoring
during the early months of treatment.
They also plan on researching whether or not diet
restrictions and additional medications for weight and glucose control will
help balance the potential negative effects of the drugs.
The review examined the
2007-2008 dental records of U.K. children, 211 of whom were Plymouth
five-year-olds. This number was just under the national average of 30.9
percent, but other regions were significantly worse.
The United States had similar
rates. Almost half of children ages 12 to 15 and about one in four American
children aged 2 to 5 is affected by tooth decay. Overall, it affects 4 million
children in the U.S. alone. Americans consumed an average of 23.8 pounds of
candy each in 2008, and with the
holiday season approaching, parents should be on the watch for cavities.
As Halloween approaches,
candy consumption is likely to skyrocket, but there are plenty of ways to
protect trick-or-treaters from tooth decay. Try these five tips to help reduce
the amount of sugar:
1. Choose reduced-sugar or sugar-free candies. Most stores carry equally tasty sugar-free or
reduced-sugar versions of Halloween favorites, including chocolate, peanut
butter cups and various filled or hard candies. These options won’t completely
eliminate the risk of tooth decay, but they can significantly cut sugar intake.
2. Give out unconventional goodies. When it comes to candy, sugar-free gum is your safest
bet. Candies that can melt and/or stick to teeth are the worst. Other ideas
might include stickers, press-on tattoos, plastic rings, or other small toys.
3.
Go to a Halloween program or event.
Choosing alternatives to trick-or-treating significantly cuts the candy haul.
These events are a great place for adults and children to socialize while
enjoying snacks and fun activities.
4. Set a limit. Put a limit on the amount of candy a child is allowed daily. This
helps prevent candy binges while reducing sugar consumption. Candy can also be
used as a reward for good behavior.
5. Donate excess candy. Many communities have programs that will send it to
troops or donate $1 for every pound of candy donated. Candy can also be donated
to fire stations, schools (for rewards), or other offices in the community.
Regularly brushing teeth and
reducing sugar intake can help prevent cavities. Consuming fewer sweets can
also help decrease children’s risk for obesity and diabetes. Dentists and parents
alike recommend that candy be consumed in moderation.
Forty-two percent of the
women in the study trying to conceive experienced infertility, but pregnancy
was more likely for women who became obese after age 18. The good news is,
surgical weight loss may increase fertility.
The study, the Longitudinal
Assessment of Bariatric Surgery (LABS), provided information on the fertility
of obese women considering surgical weight loss procedures.
Obesity can interfere with a
woman’s hormone levels, making it difficult to become pregnant. This also makes
vitro procedures less likely to work. Even in the event of conception, there
are major health risks to both mother and child. Not only are miscarriage rates
higher, but there are also a higher rates of premature and still-births.
Weight loss surgery, also
known as bariatric or metabolic surgery, which includes gastric bypass surgery
and lap banding, may help obese women trying to conceive. Many women don't
know that having such a procedure is an option.
Research shows that
bariatric surgery can reduce pregnancy complications for obese women, and LABS
participants were no exception. Roughly 62 percent of LABS participants who
underwent surgery who hoped to conceive experienced at least one live birth
after infertility.
After weight loss surgery,
doctors advise women to wait at least 18 months after surgery (6 months after
banding) before trying to become pregnant. They also suggest using
contraceptives while waiting for the body to become more stable.
“As the incidence of obesity
increases in the United States, women’s health care practitioners are likely to
care for a substantial number of patients who will undergo bariatric surgery,”
says Dr. William Gibbons of the American Society for Reproductive Medicine. “Studies
like this one are extremely useful to help us determine how to advise these
patients and best meet their needs.”

After menopause,
many women experience weight gain, which increases the risk of developing
metabolic conditions. For women with type 2 diabetes, weight loss and glucose
management can become extremely difficult to manage. Researchers found that
both CLA and safflower oil proved particularly beneficial to postmenopausal
women with type 2 diabetes.
CLA, conjugated
linoleic acid, is an unsaturated fatty acid found primarily in meat and dairy
products of cows, goats and sheep. CLA has been known to help people wishing to
build muscle, lose weight and prevent heart disease.
Safflower oil is a
plant-based oil similar to sunflower oil that is used in cooking oils, salad
dressings and some margarines. Safflower oil, SAF, is a colorless and
flavorless source of omega-6 fatty acids, and has been known to promote
healthier skin and hair, reduce cholesterol and boost the immune system.
Thirty-five women
completed a 36-week study comparing the effects of CLA and safflower oil on
weight and body mass. Each supplement was consumed for sixteen weeks. Participants
took roughly two teaspoons of either oil daily.
CLA began to cut
body fat and reduce BMI after just eight weeks. “This magnitude of reduction
has not been reported in an intervention that used a linoleic acid-rich oil,”
wrote lead authors Martha Belury and Leigh Norris, both from the Department of
Human Nutrition at OSU.
Safflower oil,
originally meant for baseline comparison, yielded exciting changes of its own.
Safflower oil reduced trunk mass and increased lean muscle mass, resulting in
an average loss of 6.3 percent of body fat. It also reduced insulin resistance
and fasting blood glucose levels.
“I never would have
imagined such a finding,” Belury says. “This study is the first to show that
such a modest amount of linoleic acid-rich oil may have a profound effect on
body composition in women."
Belury and
associates are pleased with the results of their study, and hope to explore the
effects further. They believe that CLA and safflower oil show great promise in
weight and glucose management for women with type 2 diabetes.
“It is possible
that further reductions in BMI are achievable with a longer length of
supplementation,” the authors wrote. “The use of lower doses of CLA over longer
durations of intervention may prove to be an effective weight-loss aid."
The study appears online in The Journal of Clinical Nutrition.
According to a report in The New England Journal of Medicine, sugar consumption has risen 30 percent over the last decade. For teens and children, soda accounts for 10-15 percent of total calories consumed. By removing just ¼ of the sugar in sweetened beverages, consumers can reduce annual caloric intake by 8,000 calories. This figure equates to roughly two pounds of weight in a year.
“Americans consume about 250 to 300 more calories daily today than they did several decades ago,” according to authors Kelly D. Brownell, Ph.D., and Thomas R. Frieden, M.D., M.P.H. “Though no single intervention will solve the obesity problem, that is hardly a reason to take no action.”
Such a high rate of sugar intake can do more than expand the waistline. It can also increase the risk of type 2 diabetes, heart disease, and other problems as a result of poor nutrition and weight gain. The objectives of those in support of a tax are twofold—to lower consumption, and to encourage soft drink producers to decrease the amount of caloric sweeteners in their products.
There are strong arguments on both sides. People arguing against the tax point out that food is necessary to survive. They believe raising prices will make it more difficult for low-income families to eat. Others argue that the poor would benefit the most. As the price of fresh produce and other healthier options goes up, soda and junk food prices are going down. People with tighter budgets consume more of the cheap but less nutritious foods and beverages.
“As Coca-Cola prices increased by 12 percent, sales dropped by 14.6 percent,” Frieden and Brownell wrote. Analysts believe that a 1 cent-per-ounce price increase could reduce consumption by as much as 10 percent. Justin Wilson, senior research analyst for the Center for Consumer Freedom, argues that such a tax is manipulation against the consumer. “The tax code should not be used as a method for social engineering, and that’s what this is,” he said. Legislators see the issue a little differently.
Higher prices have been used effectively in the past to reduce tobacco sales, and any revenue from a tax on soda could raise up to $14.9 billion per year. This money could be used to support health reforms or other programs. New Yorkers’ support rose by 20 percent when lawmakers suggested using these funds for obesity prevention programs.
UT Southwestern conducted a study on the effects of different types of fats on the hypothalamus and other parts of the brain. “Normally, our body is primed to say when we’ve had enough, but that doesn’t always happen when we’re eating something good,” said study author Dr. Deborah Clegg, assistant professor of internal medicine at UT Southwestern. What they found was that certain fatty acids blocked hormone signals from insulin and leptin, hormones that regulate weight and appetite.
The study examined the effects in rats. The animals received equal amounts of different types of fats. The first group of rats was fed a diet high in palmitic fatty acids, the second monounsaturated fatty acids, and the third with oleic fatty acids. These groups were then divided further into two groups. In the first group, fats were directly injected into the bran via the carotid artery, while the second group of rats received fats via a tube.
“We found that the palmitic acid specifically reduced the ability of leptin and insulin to activate their intracellular signaling cascades,” Dr. Clegg said. “The oleic fat did not do this. The action was very specific to palmitic acid, which is very high in foods that are rich in saturated fat.”
Oleic acids are naturally-occuring “good” fats found in foods such as olives and some types of soybeans. Palmitic acid, in contrast, is a type of saturated fatty acid typically found in foods high in animal fats, such as beef, butter, and cheese. These types of fats are intended for long-term energy storage, but when a person consumes a diet high in palmitic acid it can accelerate obesity.
“What we’ve shown in this study is that someone’s entire brain chemistry can change in a very short period of time,” Dr. Clegg said. The study showed that the effects of these types of fats can last as long as three days.
“Our findings suggest that when you eat something high in fat, your brain gets 'hit' with the fatty acids, and you become resistant to insulin and leptin,” she said. “Since you’re not being told by the brain to stop eating, you overeat.”

Gestational
diabetes had been connected to cardiovascular disease prior to this study, but
little was known of the links between minor glucose intolerance and heart
disease. Type 2 diabetes and cardiovascular disease share several
characteristics including obesity, insulin resistance and cholesterol problems.
Oftentimes, individuals with one condition will develop the other. Women with
gestational diabetes may experience similar metabolic complications as soon as
3 months after giving birth. Researchers
analyzed the medical records of all Ontario women between the ages of 20 and 49
who had given birth between April 1994 and March 1998. Participants were divided into three
groups: those who were diagnosed with gestational diabetes, those who received
an oral glucose tolerance test, and those who were not screened using oral
glucose testing. One birth was selected at random for women with multiple
deliveries; the median ages were between 29.2 and 31.1.
Women are
tested for gestational diabetes (a type of diabetes that develops when women
experience unusually high glucose levels during pregnancy) during the second
trimester of pregnancy (13-27 weeks). The first step is a glucose challenge
test, taken by measuring glucose levels one hour after ingesting a sugary
substance such as glucola. If results are abnormal (≥7.8 mmol/L), a second oral
glucose tolerance test (OGGT) is taken.
Participants
in the study were followed up until March 31, 2008, providing information
reflecting cardiovascular disease development for a median of 12.3 years after
childbirth. “If you followed 10,000 people for one year,
4.2 of them would have an event,” Dr. Shah explains. “If you followed those
10,000 people for 10 years, 42 of them would have an event…In other words, these are extremely rare events.”
Although
the differences were minor—absolute risk was 0.16% and 0.05% for women with
gestational diabetes and women who received an OGGT, respectively—the results
indicate a need for further research. "We shouldn't be ignoring these mild
abnormalities during pregnancy,” Dr. Shah says. “(They) may benefit from extra
surveillance and/or cardiovascular disease screening.”
More
information is needed to establish the exact relationship between glucose
intolerance and cardiovascular disease. In the meantime, proper nutrition and
exercise may reduce your risk for both gestational diabetes and cardiovascular
disease.

Vitamin
D deficiency can result in conditions such as rickets in children (usually
<11 ng/mL), and osteomalacia and osteoporosis in adults (typically levels
<25 ng/mL). Low levels of vitamin D also increase the risk of bone and heart
disease, and are also associated with higher blood pressure and lower calcium
and HDL cholesterol levels in later life.
Children classified as
“insufficient” had 15-29 ng/mL, while those who were classified as “deficient”
had levels of 15 ng/mLor less. Normal range, according to the National
Institute of Health, is 30-74 ng/mL.
The study is the largest of
its kind to date, gaining nationwide rather than just regional data. "We
expected the prevalence of vitamin D deficiency would be high,” says lead
author Juhi Kumar, M.D., M.P.H., of the Children's Hospital at Montefiore
Medical Center, “but the magnitude of the problem nationwide was
shocking."
Vitamin D deficiency is more
common for female children, those that are older, obese, drink less than one
glass of milk week, and those who spend four hours or greater on the computer
or watching television per day. African-American and Mexican-American children
also had a greater risk.
Melamed,
co-leader of the study, attributes part of this problem to lifestyle,
recommending parents send their children outdoors. One source of vitamin D is
UV-B sunlight, which converts cholesterol in the skin into vitamin D. She also recommends ditching
the sunscreen for a while: “Just 15 to 20 minutes a day should be enough…don't
put sunscreen on them until they've been out in the sun for 10 minutes, so they
get the good stuff but not sun damage.” Individuals with darker skin and those
who live in northern regions with less sun exposure should spend more time
outdoors.
The American Academy of Pediatrics recommends that children and teens get at least 400 IU per day, double the previous recommendation of 200IU per day. Good sources of vitamin D include fish, milk, eggs, cod liver oil, and fortified foods. Vitamin D levels can also be increased with the use of supplements.
The study's abstract is available online, and will be published in September's issue of Pediatrics.
Obese women should limit weight gain to between 11 and 20 pounds during gestation, according to an updated set of pregnancy weight gain guidelines released Thursday by the Institute of Medicine. Previously, the Institute did not recommend a specific gestational weight gain range for obese women, but the section was added in response to increasing obesity rates and high weight gain trends in pregnant women. This is the first time the Institute has issued new pregnancy weight gain guidelines in nearly 20 years.
Restless legs syndrome (RLS), a medical condition characterized by uncomfortable sensations that create an irresistible urge to move the legs during sleep, may be linked to obesity and belly flab according a study published this week in Neurology. The previously obscure neurological disorder has recently attracted attention after late-night commercials about RLS medications brought the condition into the medical limelight.About | Privacy Policy | Business Solutions | Advertise | Contact | Add Healia to your site
