Columbia’s Initiatives on Obesity Prevention

Mailman School faculty continues to generate scientific knowledge on obesity through the schoolwide Obesity Prevention Initiative which puts a special emphasis on prevention. Dr. Y. Claire Wang, associate professor of Health Policy and Management, and Dr. Andrew Rundle, associate professor of epidemiology, lead this initiative with a goal of producing position papers and a vision for more effective strategies for obesity prevention. A symposium titled  “ A Smart Start: Preventing Childhood Obesity” is scheduled for April. Other upcoming events include a Grand Rounds talk by nutrition expert Dr. Marion Nestle and one on the social epidemiology of eating by the author of Why Diets Fail.

Neighborhood Park Features Associated with Body Mass Index
The size and cleanliness of a neighborhood park has a strong association with the body mass index (BMI) of the neighborhood’s residents, according to research by Dr. Andrew Rundle, Dr. Gina Lovasi, and colleagues. Findings are published online in the journal Preventive Medicine.

Teens Who Average Six Hours of Sleep a Night More Likely to Be Obese

Obesity-Attributable Absenteeism Among U.S. Workers Costs the Nation More than $8 Billion
A study by Dr. Claire Wang shows that obesity costs the U.S. $8.65 billion per year as a result of absenteeism in the workplace. The study is the first to provide state-level estimates of obesity-attributable costs of absenteeism. Findings are in the Journal of Occupational and Environmental Medicine.

Taking Antibiotics During Pregnancy Increases Risk for Child Becoming Obese
Children who were exposed to antibiotics in the second or third trimester of pregnancy had a higher risk of childhood obesity at age 7. The research led by Dr. Andrew Rundle also showed that for mothers who delivered their babies by a Caesarean section, whether elective or non-elective, there was a higher risk for obesity in their offspring.

Nutrition Intervention Led to Sustained Dietary Behavior Changes Among Latina Breast Cancer Survivors
Dr. Heather Greenlee, assistant professor of epidemiology, and colleagues in partnership with the not-for-profit Cook for Your Life initiative published the results of an intervention designed to provide Latina breast cancer survivors with the knowledge and skills needed to change and sustain dietary behaviors. The Cook For Your Life program helps survivors, who are at higher risk of obesity and low physical activity, adhere to recommended guidelines to eat a diet high in fruits and vegetables using a culturally based hands-on educational approach. The participants increased their number of fruits and vegetables servings to 6.8 per day and also lost 2.5 percent of their body weight. Read more and link for journal paper.

Markers of Obesity and Cardiovascular Risk

Dr. Ryan Demmer, associate professor of epidemiology, collaborated on research linking the markers of obesity to subclinical cardiovascular risk, as well as research regarding the role of the oral microbiome in cardiometabolic risk. Two recent papers are: “Periodontal Infection, Impaired Fasting Glucose and Impaired Glucose Tolerance: “ and “Periodontal Infection and Cardiorespiratory Fitness in Younger Adults.”

“First Steps to Healthy Living” Team Assesses Health Behaviors and Obesity Rates of Children Enrolled in NY State WIC Nutrition Program
Research by the “First Steps to Healthy Living” team, led by Dr. Sally Findley, professor of population and family health and sociomedical sciences, Dr. Mary Ann Chiasson, department of epidemiology and Dr. Jackson Sekhobo, Bureau of Nutrition, New York State Department of Health, looks into relations between eating behaviors, activity patterns, and obesity rates among infants and toddlers enrolled in the NY State WIC program.  Findings from two rounds of surveys at WIC sites statewide show that adopting the WIC-recommended lifestyle changes of breastfeeding, delayed introduction of solid foods and reduced screen time contributed to reducing sweets and sweetened drink consumption.

The “First Steps to Healthy Living” has just completed the last round of statewide surveys, supported by a grant from The Robert Wood Johnson Foundation, and Dr. Findley and colleagues will use these survey data as well as focus group data and NYS WIC data to produce a series of manuscripts over the next six months on early childhood obesity.
