Obesity Opportunities to Improve Food Access

 

Local governments can address access to healthy food and transportation through policy and planning. A paper published in November is the first study to examine municipal-level transportation supports for food access. The authors found opportunities to improve food access through transportation, especially in smaller and Southern communities. The study used a nationally representative sample of US municipalities with 1,000 or more people.   Prevalence of municipal-level policies dedicated to transportation that consider food access.

In Case You Missed It   A paper published in September reported that that among 432,302 persons aged 2–19 years, the rate of body mass index (BMI) increase approximately doubled during the pandemic compared to a prepandemic period.   This Mission:Readiness podcast includes an interview with Dr. Aly Goodman, one of the paper’s authors.

Physical Activity

 

Measuring High School Students' Physical Activity

The US youth physical activity guideline recommends participation in four types of physical activity. An analysis of 10,596 US high school students found that: 15.2% met the guideline for moderate-to-vigorous intensity aerobic activity. 50.7% met the muscle-strengthening guidelines. 70.6% met the vigorous-intensity aerobic guidelines. 80.7% met the bone-strengthening guidelines. In total, 11.2% of the students met all four components. The authors concluded that, “incorporating additional measures of vigorous-intensity and bone-strengthening activities into current surveillance systems may not meaningfully impact national estimates of meeting the youth physical activity guideline.”   Surveillance of meeting the youth physical activity guideline: Impact of including vigorous-intensity and bone-strengthening activities.

Delayed Cord Clamping Varies by Hospital Location and Cesarean Birth Rate

 

Delayed cord clamping allows transfusion of placental blood to the newborn in the first minutes after birth. Of 2,042 US hospitals analyzed, 50% reported that “most” healthy newborns received delayed cord clamping. The prevalence varied by hospital location and cesarean birth rate.   For term newborns, delayed cord clamping increases hemoglobin and iron stores, preventing or delaying iron deficiency, and may improve young children's development. It is recommended by the American College of Obstetricians and Gynecologists.
