A new study released this week of over 30 thousand US children found that, on average, kids snack three times a day. What’s more, over half of these children snack 4 times a day. Compared with data from the 1970s which show children consuming over 400 daily calories from snacks, kids today consume nearly 600 daily calories from snack food alone. “My underlying fear is that we’re moving away from being hungry and eating for satiation to just eating,” said Dr. Barry M. Popkin, co-author of the study and director of nutrition epidemiology at the University of North Carolina. Although caloric intake from snacks have increased over time, the average child’s total daily calories have only increased by 113 calories. This means that snack calories have replaced mealtime calories, which is not a good thing since sweet snacks (cookies and cakes) and salty snacks (chips and pretzels) are the top two most consumed categories of snack.

A new study in this month’s issue of the journal Obstetrics & Gynecology demonstrates that excessive weight gain during pregnancy, especially in the first trimester, can increase a woman’s risk of developing gestational diabetes mellitus (GDM). Although it’s known that too much weight gain can lead to GDM (which is one of the reasons why doctors carefully follow a pregnant woman’s weight), results from the current study shows that women who gained more weight during pregnancy than recommended by the US Institute of Medicine were 50% more likely to develop the disorder. GDM can lead to early delivery, increased risk of c-sections, type 2 diabetes in the mother post-partum, and even increases the likelihood that the child will develop diabetes and obesity later in life.

In light of First Lady Michelle Obama’s initiative to combat childhood obesity, updated data shows that the rate of childhood obesity has, indeed, not declined. According to the most recent National Health and Nutrition Examination Survey (NHANES 2007-2008), the percentage of obese children, defined by BMI, has remained steady with nearly 17% of children having BMIs above the 95th percentile. This figure is identical to a decade ago when childhood obesity skyrocketed from approximately 5% to 17% between 1980 and 1999. Does this mean that the rate of childhood obesity has plateaued? Are we finally seeing the result of years of effort in attempting to curb childhood obesity? Perhaps, but one thing we know is that the rate has not declined and continued effort is much needed in order to reduce the future health burden obesity can confer on these children.

A study published in the latest issue of Morbidity and Mortality Weekly Report, published by the U.S. Centers for Disease Control and Prevention, examines the New York City Department of Education’s 2004 decision to eliminate whole and flavored milk from its schools. The study states the substitution of low-fat and fat-free milk for whole milk in schools can greatly reduce students’ consumption of calories and fat and help combat the childhood obesity epidemic (40% of New York City children are obese by the age of 11).  This simple change means that a milk-drinking student was exposed to 33 fewer calories and 3.4 fewer grams of fat per school day, which is equivalent to 5,960 fewer calories and 619 fewer grams of fat per year. Initially, the consumption of milk by students declined, but by 2009 had increased to 1.3% above the rate at the start of the initiative. But will decreasing caloric intake from milk reduce overall caloric intake and make a dent in the childhood obesity epidemic? It’s a great idea, but there are many more high-calorie foods out there beyond milk to contend with. [via HealthDay]

Two of the world’s foremost metropolitan cities have joined together to fight childhood obesity. In a report titled “A Tale of Two ObesCities” researchers from London Metropolitan University and City University of New York have found demographic similarities between obese children in both cities. Notably, both cities are characterized by high levels of income disparity with the poorest children having the highest rates of obesity. In London 36.3% of children are obese by the age of 11, compared with 40% in New York. The report demonstrates that the two cities can benefit from collaboration and learning from each other’s experiences in combating childhood obesity. The main recommendations of the report include:

- Build active design principles into building codes, housing strategies

-Promote and support urban agriculture as a sustainable and health promoting use of green spaces

-Promote access to places where people can by physically active and promote walking and cycling

-Implement a universal free school meal program with nutritional standards

-Promote research to help cities understand how the beat health inequalities

This past week new data suggested that some people taking the anti-obesity drug Meridia (sibutramine) are at greater risk of heart attacks and strokes than people taking a placebo. It also raised blood pressure and heart rate among users. What is interesting is how two large regulatory agencies responded to this data. The European Medicines Agency (EMEA) has already advised physicians and pharmacists to stop prescribing and dispensing the medication, while the U.S. FDA has urged pharmaceutical company Abbott Laboratories, the maker of Meridia, to place a stronger warning on the drug. The warning is to caution against the use of the drug by people who are already at increased risk of cardiovascular disease. Was the EMEA too hasty in its decision or is the FDA not forceful enough? Proponents of the drug agree that it shouldn’t be given to those with cardiovascular disease or diabetes, while critics are in favor of an overall ban. In the drug’s twelve years on the market it has been linked to more than 80 deaths, including 30 people under age 50. [via New York Times]

Researchers from the Karolinska Institute are embarking on a new paradigm in exercise physiology after publishing a paper in this month’s British Journal of Sports Medicine. The study authors argue that prolonged periods of sitting is an entity distinct from the commonly used terminology “sedentary behavior,” which means a general lack of exercise. Rather, they contend that the use of the term “muscular inactivity” more accurately describes a state of being in which people have prolonged periods when even light physical activity is not achieved. This is important because research shows that periods of prolonged sitting and lack of whole body muscular activity is strongly associated with the development of diabetes, obesity, heart disease and cancer, regardless of whether moderate or vigorous exercise was performed. This goes to show that maintaining an intermittent level of activity that involve total body muscle movement (climbing stairs, walking to run errands, taking a walking break during sedentary work) is just as important as incorporating moderate to vigorous exercise into your routine.

The American Academy of Family Physicians (AAFP) announced last month a new program called Corporate Alliance, in which the AAFP partners with interested companies to produce educational material for the general public. The first of these companies to sign on is Coca-Cola, who has donated $500,000 to the AAFP which will be used to develop consumer education content related to beverages and sweeteners. Not surprisingly, many physician-members of the AAFP have voiced strong opposition to such an alliance, especially in light of the current obesity epidemic. AAFP President-elect, Lori Heim, M.D., states the partnerships will not include an AAFP endorsement of any brand, product or service, and the Academy will maintain editorial control of all materials related to the partnerships. However, this partnership of irony calls into question the integrity of AAFP leadership, who’s efforts should be devoted to primary care and prevention, not sleeping with the enemy. [via AAFP]

Today’s Daily Dose comes from the current issue of Neurology, the medical journal of the American Academy of Neurology. Researchers found, after following over 238 thousand women over the course of 40 years, that women who had a BMI of 30 or greater at the age of 18 had more than twice the risk of developing multiple sclerosis (MS), compared to women with a BMI between 18.5 and 20.9. “Our results suggest that weight during adolescence, rather than childhood or adulthood, is critical in determining the risk of MS,” said study author Kassandra Munger, ScD, of the Harvard School of Public Health. The study authors theorize the link between obesity and MS may be that obese women tend to have lower vitamin D levels (higher vitamin D levels are thought to reduce the risk of MS). In addition, fatty tissue can produce substances thought to affect immune and cellular function which may be associated with MS. [via Medical News Today]

An article in the September 17th issue of the New England Journal of Medicine proposes that a national “soda tax” of 1 cent per ounce of soda and other sugar-laden drinks could curb the United State’s obesity epidemic while generating funds to promote obesity prevention programs. While this tax strategy has reduced cigarette and alcohol use, will it would work with food? That remains to be seen. “There are certain products which make a strong contribution to the obesity epidemic while, conversely, there is no plausible public health benefit [from them],” noted Dr. David Ludwig, senior author of the paper and associate professor of pediatrics at Harvard Medical School. Opponents of such an idea say that singling out a specific food type sends the wrong public health message. Rather, they say, the government should promote proper nutrition education. Would a heftier price stem your appetite for soda? [via BusinessWeek]
