The Aetna survey of 1,800 Americans ages 25-64 conducted online by Harris Interactive found after the office, the most stress people experience involves their extended family, and then their spouse or partner.
Although family is a major cause of stress, four-legged family members help reduce it. Nearly 7-in-10 people said having a cat or dog helps calm their nerves.
Almost 7-in-10 adults also said they need to lose a considerable amount of weight -- a median of 25 pounds. Baby boomers are more likely than millennials to say that "healthy" is associated with being the right weight for body type and height. Men are happier than women with their current weight and women are more likely to want to lose weight.
In addition to their different views on weight, men are more likely than women to define healthiness in terms of a major fitness event or goal, like a marathon. Upcoming events such as reunions and weddings kick-start healthier living for women more than men.
Americans give themselves fairly high marks on health status with an average score of 70.1 on a 0-100 scale, the survey found.
About a third of people said they're living healthier today than five years ago. Forty-seven percent said they were choosing side salads instead of french fries, 37 percent reduced alcohol consumption and 34 percent said they added tougher workouts as ways of living healthier lives.
The survey was conducted April 8-19. No margin of error was offered.
The findings are scheduled to be published Family Circle, Ladies' Home Journal and Fitness.
