 Wei Perng, PhD, MPH Sitting the month. Most women of Asian or Middle Eastern descent can rattle off a list of things a new mother must not do in the month following delivery. The most common examples include: taking a bath, washing her hair, drinking cold beverages or foods, touching cold water, washing dishes, lifting heavy items (probably an all-around good idea anyway), sitting in front of a fan… and heaven forbid, do not even think about leaving the house. In Mandarin, we call this “sitting the month.” The motivation behind these rules, which have been featured on NPR, is to protect the recuperating mother from environments that may leave her vulnerable to chronic conditions later on. As wacky as these ideas seemed to me as a child, I recently began to wonder whether the postpartum period is, indeed, a sensitive period for a new mother’s future well-being. While there is little scientific research on this topic, the postpartum period is undoubtedly a time of rapid change in hormones, weight, and lifestyle that could set the tone for health down the road.

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.
 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?
 Karen Switkowski, MPH, PhD Most parents, nutritionists and educators will agree that it’s not easy to get kids to eat fruits and vegetables, especially in school. In this earlier blog post, Dr. Jenn Woo explained the importance and effects of improved school meal standards, which have since been changed again by the Trump administration. It is well-established that providing nutritious, affordable school meals is important in controlling childhood obesity and there is broad support for this initiative from physicians, and former First Lady Michelle’s Obama’s Let’s Move campaign. However, the best way to implement improved standards is controversial. There’s also the important question, raised in Dr. Woo’s post, of whether kids will actually eat these healthier meals and learn to appreciate fresh, nutritious food.
