Study: How to save money while preventing childhood obesity

By Posted on 1 Comment on Study: How to save money while preventing childhood obesity

Taxes on sugary drinks and unhealthy food advertising to kids may save more than $30 in health care costs for every dollar spent to implement, suggests a new study published this month.

Childhood obesity rates are nudging upwards, which means more kids are at risk for obesity in adulthood. With this extra weight comes increased risk for cancer, heart disease, and diabetes, as well as the high costs of health care that come with these diseases.

The new study used previous research to analyze the cost effectiveness and impact on childhood obesity of 7 proposed interventions. Six of the interventions aimed to prevent weight gain in youth while one involved surgical treatment of obesity. With the help of policy makers and other experts, study authors estimated the the effect of each intervention among the US population over the 10 years spanning 2015 to 2025.

Overall, five strategies were found to decrease incidence of childhood obesity (see chart) with three saving more in healthcare costs than they cost to implement.

Obesity cost effectivenesssOne strategy was a tax on sugary beverages. The proposed tax, translating to 12 cents for a can of soda, would prevent an estimated 576,000 children from being obese and save $30 for every dollar it cost to enact.

Another effective strategy was to create nutrition standards for school snacks, fundraisers and other foods sold outside of school meals. This would prevent an estimated 345,00 cases of childhood obesity, saving about $4.50 for every dollar it costs.

Nutrition standards for school meals was found to prevent the most cases of childhood obesity — approximately 1.8 million cases — yet this strategy cost about 60 cents more to implement than it would save in healthcare costs.

These results demonstrate the importance and feasibility of prevention measures to reduce childhood obesity, note the authors. The sugar sweetened beverage tax and taxing advertising would also provide revenue that would offset the costs of other prevention efforts, such as nutrition standards for school meals. Future studies are needed to assess the cumulative impact and costs of these interventions.

This study was funded by The JPB Foundation, The Robert Wood Johnson Foundation, the Donald and Sue Pritzker Nutrition and Fitness Initiative, and the Centers for Disease Control and Prevention.

Study: Kids’ peers may help them eat more veggies

Kid eating carrotsWhat kids think their peers are eating may matter for how many vegetables they’re eating, suggests a new study. The study was published in the International Journal of Behavioral Nutrition and Physical Activity and could have an impact for cancer prevention decades later. Healthy eating habits can reduce risk of kids being overweight adults, and excess body fat is a cause of ten cancers for adults.

For this small study, 143 children ages 6-11 were recruited from North-West England and brought in individually for what they thought was a study of game-playing ability.

Children were shown a participant information sheet of six fictitious previous participants that included general information as well as the amount of carrots each child ate during the session. The carrots column either read “all” (high intake group), “none” (low intake group); the column was blank or omitted in two control groups. Children were also presented with a bowl. The bowl contained one carrot in the high intake group, was nearly full of carrots in the low intake group, and was filled with pens for the control groups.

How can bariatric surgery and a mom’s smartphone link to reduced cancer risk?

These studies were among the winners of the AICR research poster competition, announced yesterday at the annual Obesity Week conference. Obesity is associated with increased risk of a number of cancers, including ovarian, endometrial, and colorectal. The winners, awarded support by AICR, included three early investigators and two student prizes.

In no particular order, here are highlights of this year’s winners for outstanding posters. Congratulations to all. Note: these poster findings are not yet published and have not yet gone through the peer-reviewed process.

Ǻsa Anveden, MD PhD University of Gothenburg, Sweden

AvendenBariatric surgery is one obesity-treatment option and previous research suggests decreased risk of cancer following surgery. This surgery may reduce the risk of cancer in obese women, suggests the finding of this study.

Anveden and her team followed over 4,000 obese people (70% women) for up to 26 years to look for cancer incidence. About half the participants had undergone bariatric surgery, and they were matched to a group of obese controls who received usual care.
