The Study

Changes in diet and physical activity resulting from the Strong Hearts, Healthy Communities randomized cardiovascular disease risk reduction multilevel intervention trial

In simple terms

This study is like a fair test where two groups of women tried different ways to eat better and move more. One group got extra classes and support, and the other got just a few talks. The test showed that the group with extra classes ate more veggies — so we can say the classes probably helped with that. But when we measured how much they actually moved with special watches, there was no big difference.

What’s the bottom line?

Women in rural towns got either weekly classes on eating healthy and walking, or just a few talks. Those with weekly classes ate more fruits and veggies and said they walked more, but machines didn’t show they moved more overall.
