The First 1000 Days Of Life: A Window Of Opportunity For Novel Interventions Of Childhood Obesity1/3/2018  Izzuddin Aris, PhD Childhood overweight/obesity remains a substantial problem globally. Rising trends in children's and adolescents' body mass index have plateaued in many high-income countries, childhood obesity rates have dramatically increased in parts of Asia over the past few decades. Mounting evidence suggests that the period between conception and age 2, otherwise known as the “first 1000 days of life”, is important in shaping a child’s future risk of obesity. While previous studies have identified numerous maternal factors that can boost subsequent childhood obesity risk (e.g., maternal obesity, diabetes, excessive weight gain during pregnancy, etc.), researchers have only considered them in isolation. Recent findings from the Project Viva and Southampton Women’s Survey cohorts have highlighted that these interlinked risk factors, both independently and cumulatively, contribute to a child's future risk of obesity.

 Jen Thompson, MPH You may have noticed that our department recently changed its name. After much debate and brainstorming, we decided to retire our old name, “Obesity Prevention Program”, and call ourselves the Division of Chronic Disease Research Across the Lifespan (CoRAL). But what prompted us to make the change?
 Peter James, MHS, ScD With the wide availability of wearable fitness trackers, people have been increasingly measuring the number of steps they take per day, striving to obtain those 10,000 steps. But what is the significance of 10,000 steps? And is counting steps really a good measure of physical activity? I recently attended the International Society for Behavioral Nutrition and Physical Activity (ISBNPA) Annual Meeting in beautiful Victoria, British Columbia where I was fortunate to gain more insight into the step counting phenomenon.
 Jason Block, MD, MPH More than 40% of all food consumed in the United States is prepared, or ready-to-eatfood. Widespread policy change is underway, including calorie labeling and enhancements to the Nutrition Facts panel, to guide customers to healthier choices when dining in restaurants or buying prepared food. But convincing customers to make changes in fast-paced settings is difficult. Price and taste often quickly overtake health concerns. Why can’t we just change the default options to be healthier?
 Sheryl Rifas-Shiman, MPH In the August 2017 issue of Pediatrics, several colleagues and I reported that mothers who consumed more sugary beverages – including sugary soda and fruit drinks – in mid-pregnancy had children with higher amounts of body fat in mid-childhood, even when we considered the children’s own intake of sugary beverages. We also examined the effect of drinking water and 100% fruit juice during the same time period, and found no associations between these drinks and children’s later body fat. We hypothesized that the second trimester of pregnancy may be a sensitive period with regards to children’s body fat deposits, and that avoiding high intake of sugary beverages during pregnancy may reduce the risk of childhood overweight and obesity.
