Why is obesity more prevalent in America now than it was 25 years ago? Ask that question to anyone you know, and their answer will likely include an explanation of how Americans are eating more now than we were then. But is there is another side to the equation? Is it possible that America’s collective weight gain has been due to a decrease in physical activity, rather than an increase in calorie intake? A new study published in The American Journal of Medicine (Ladabaum, et al, 2014) suggests that very idea, finding that while our calorie intake has remained the same over the last two decades, our physical activity has plummeted, factors that are positively associated with increased obesity.

  1. 1. OBESITY & lack of physical activity What We Already Know Increased waist circumference is an independent predictor of morbidity and mortality even in persons with a normal body mass index (BMI). For most Americans, physical activity can protect against weight gain and lowers the health related risks associated with obesity and Recently, The American Journal of Medicine® published a study titled “Obesity, Abdominal Obesity, Physical Activity and Caloric Intake in US Adults: 1988 to 2010.” Following are the study’s key findings. The average daily caloric intake in the US has not 1 significantly changed over the last 2 decades. 1988 - 2010 2524.5 2450 1724.4 1759.4 1988 2010 3000 2500 2000 Fewer Americans are engaging in leisure-time 2 physical activity. 100 80 60 40 20 While Americans are eating basically the same number of calories, the incidence of abdominal obesity is increasing, especially in younger women. 3 AVERAGE CALORIC INTAKE The Facts The average waist circumference decreased in both women and men when they increased their physical activity by 100 minutes per week.

Physical activity reduces the eect of these risks. Abdominal obesity is defined as waist circumference greater than 34 inches for women and 40 inches for men. KEY FINDINGS abdominal obesity.
