Smoking is known to contribute to bone loss has been threatening risk even girls who have known depression and smoking habits. At an early age, the body is building bone may be hampered by the ill effects of smoking.

Smoking habits, depression, and anxiety have been linked to lower bone density in adults. Researchers intend to determine whether the smoking habit that began in their teens have a similar effect on bone.

The researchers conducted an assessment of the adverse effects of smoking associated with depression and anxiety on bone mineral density (Bone Mineral Density / BMD) involving 262 teenage girls aged 11 to 19 years.

During the study, the girls receive annual clinical exams for three years. Each visit, the doctor using dual energy x-ray absorptiometry to measure total bone mineral content and bone mineral density of the hip and spine.

Doctors also identify whether young women also experience depression and anxiety. Every three months, the intensity and frequency of smoking peserya also dimonitori by researchers via telephone interview.

The result is known that teenage girls should have equal levels of BMD in the lumbar and hip. But over time, teenage girls who smoke, have lower BMD in certain parts of the body.

The girls who are depressed also had lower BMD at the back compared to girls who had fewer depressive symptoms. The level of anxiety did not affect BMD.

"Although girls are generally only permitted at a low level and varies throughout the month, but this has a negative effect on bone accrual," wrote the researchers at Cincinnati Children's Hospital Medical Center (CCHMC).

Bone development in young girls during the first two years around the first menstrual period, so that the habit of smoking at a young age would be very dangerous. Low BMD in smokers may increase the risk higher for osteoporosis and fractures later in life.

"This discovery is very important to encourage health care providers to be more aware of the smoking habit that began in adolescence and depression that negatively impact bone during crucial stages of bone development," said Lorah Dorn, lead investigator of the CCHMC.

The study was published on 4 December in the Journal of Adolescent Health, as quoted from MNN, Thursday (12/06/2012).
