In addition to tobacco and alcohol, two main risk factors with significant impacts on Thai people, , unsafe sexual intercourse is another significant risk factor, especially for women. Research indicates that in 2012 53 out of every 1,000 women (ages 15 to 19) became pregnant. In addition, there are up to 10 girls less than 15 years of age who become “child mothers” each day. Unplanned pregnancy among teenagers poses both short and long-term impacts, both to individuals and their families. The rate of sexually transmitted diseases among teenagers in Thailand is also increasing rapidly at present, rising from 62.8 cases per 100,000 in 2008 to 90.1 in 2012.
In addition to unsafe sexual intercourse, changing environments, mental health problems, stressful lifestyles, and weak consumer protection affect the health of Thai people.
