You think you know him better than you know yourself, but you’re wrong. Men are worried about their health, according to a consumer poll released by LaurusHealth.com, a consumer health information Web site created by doctors and hospitals nationwide.

The poll looked at what health issues most concern men, what women believe are the major health concerns of their husbands, and what men are doing about their health concerns.

Highlights from the survey revealed:

Forty-nine percent of men surveyed said they are concerned about heart disease, but just 40 percent of female partners perceived their concern.

Women also believe men are not as concerned about prostate cancer as they really are; 46 percent of the men expressed concern about the disease, compared to 33 percent of the women. Men are less anxious about hair loss than women think they are, with only 13 percent of men identifying it as a concern, compared to 18 percent of women.

“Men are putting their concerns into action, according to the study, and this is good news,” according to Dr. Peter J. Plantes, LaurusHealth medical director.

An overwhelming majority of men say they are eating healthier (76 percent), having annual checkups (70 percent) and exercising regularly (71 percent). However, men are not taking vitamins, herbs and minerals (3 percent) to enhance their health.

The top health concerns of men, according to the survey are:

• heart disease (49 percent)
• prostate cancer (46 percent)
• weight gain (40 percent)
• skin cancer (33 percent)
• lung cancer (30 percent)

The survey showed that men are not as concerned about hair loss (13 percent), diabetes ( 6 percent) and high blood pressure (2 percent).
