Have you ever resolved to eat healthier, only to be tempted by fast food options everywhere you look? Do you think you would exercise more if only you didn’t have to spend so much time in your car?
Many in the public health community think that factors like these play a big role in what we eat, how much we move, and what we weigh. And many communities have tried to change these factors through so-called “environmental interventions.”
Researchers from Drexel University set out to test whether these environmental interventions work in a study recently published in the journal Obesity Reviews. They conducted a systematic review looking at the impact of various environmental interventions on diet, physical activity, and obesity. Their review included 37 natural and “quasi-“ experiments. About half of these studies focused on diet.
They found that studies involving mandatory changes to the food environment—such as laws banning trans fat in restaurants or requiring healthier foods to be offered in schools—were effective in their intended outcomes. Policies that make it easier for low-income people to use their benefits to buy fruits and vegetables were also effective. Continue reading
Today, a new study found that replacing even a small amount of that sedentary time with some physical activity could reduce early death for people of all weights and waist sizes. A growing body of research is linking sedentary behavior to cancer risk.
The new analysis, published in American Journal of Clinical Nutrition, used data from over 334,000 people in the European Prospective Investigation into Cancer Nutrition (EPIC) study to determine if overweight, obesity or large waist size would affect whether reducing sedentary behavior improves survival.
The investigators compared rates of mortality over twelve years, between four levels of physical activity (inactive, moderately inactive, moderately active and active) and categorized by BMI and waist size. Continue reading
Running is a process – and a powerful one, says Scott Spitz, a cancer survivor who is currently featured on the cover of this month’s Runner’s World. A competitive runner, Scott continues to run through treatment for a rare form of abdominal cancer. We talked with Scott about why he runs and how running has helped him grapple with the physical and mental challenges of treatment.
Congratulations on winning the Runner’s World Cover Contest. Why did you decide to enter?
I was a little reluctant to enter because I didn’t want to assume my story was better than others, but I’ve heard from a lot of people who said they gained something from hearing about my experience. I’ve never won anything like this before, and I was humbled and flattered that they recognized the power of my story.
What drew you to running and why have you stuck with it?
I discovered really young that I enjoyed running and had a talent for it. I ran competitively in middle and high school, but then I didn’t run for 13 years after that. I was living in a small town and wanted a physical outlet, so I went for a run and all the experiences came rushing back. I started running regularly again and never stopped. I can cite all the health benefits of running, but ultimately I run because it gives me a sense of accomplishment that has added immeasurable value to my life. Continue reading
