The women were asked to identify the health issues they were concerned about from a list of 20 problems.
The survey showed many women thought they should be slimmer, with more than 80% saying they were overweight.
But just 43% said they were exercising at least three times a week, and 11% played team and individual sports. And less than two-thirds of all women said they get an annual physical.
"These findings should be a wake-up call to American women everywhere to make their yearly checkups without fail and make their own personal health a top priority," said Diane Salvatore, editor in chief of Ladies' Home Journal, which is published by Meredith Corp.
While the majority of women said they were overweight, 68% said they were satisfied with their "identity and development as an individual".
But 40% said it was wrong for a man to tell a woman she was overweight.
To improve their health, 26% of women said they took natural herbs and supplements, while 25% bought or adopted a pet, according to the survey.
Four percent visited a spiritual or religious leader and one percent went to a hypnotist.
