With big handbags becoming a key fashion accessory(配饰) for working women, health experts are warning they can also become a key health concern.

Bags for women have become bigger and heavier as designers combine briefcases with handbags and straps have become longer, resulting in many users complaining of neck, shoulder and back problems.

“I see so many women with neck pains and headaches and what I usually do is look for their purse and pick it up,”said Jane Sadler, a family practice physician at Baylor Medical Center in Garland, Texas.“We take it over to the scale and weigh it and usually they’re anywhere from 7 to 10 pounds. We’re really going to see women with more and more problems later on if we continue the big purse craze.”

William Case, a physical therapist(临床医生)in private practice in Houston, Texas, urged designers“to place a cute, educational caution tag(标签) on all bags to inform buyers of potential neck and shoulder dangers.”Above all, he suggested correct posture while carrying big purses, keeping the head and shoulders upright. Patients should also often change the size and weight of purses carried.

“The extra-large purses are quite extraordinary. They look beautiful when the women wear them, but I don’t know how aware they are of the potential problems,”Case said.

Placing objects on one shoulder was one of the least efficient(高效率的) ways of carrying a load, according to a professor from Cornell University in New York State.“This causes a great imbalance,”he said.“If a big bag is a fashion accessory, then occasional and symbolic use is fine. If not, then keep it light.”
