What age group has the highest rates of STD infection?

Choice A reason: Using male condoms is one of the most effective ways to prevent the transmission of STDs, especially those caused by viruses or bacteria. However, condoms are not 100% foolproof and may not protect against some STDs that can be spread by skin-to-skin contact, such as herpes or HPV.

Choice B reason: Having multiple sex partners increases the risk of getting an STD, as it exposes the person to more potential sources of infection. The more partners a person has, the more likely they are to encounter someone who has an STD or does not know their status.

Choice C reason: Delaying sexual relations as long as possible is another way to lower the risk of getting an STD, as it reduces the number of sexual exposures and the chances of encountering an infected partner. Young people are especially vulnerable to STDs, as they may have less knowledge, experience, or access to preventive measures.

Choice D reason: All of the above choices are valid ways to lower the risk of getting an STD, but none of them are sufficient on their own. The best way to prevent STDs is to practice abstinence or be in a mutually monogamous relationship with a tested and uninfected partner. Additionally, regular testing, screening, and treatment are essential for detecting and curing STDs before they cause serious complications.

Choice A reason: Congenital anomalies of the central nervous system are not a common complication of GDM, as they usually occur in the first trimester, before GDM develops. However, GDM can increase the risk of other congenital anomalies, such as cardiac defects or neural tube defects.

Choice B reason: Preterm birth is a possible complication of GDM, as it can be caused by maternal hypertension, preeclampsia, or placental abruption. However, it is not the most likely complication, as GDM can also delay the onset of labor and prolong the pregnancy.

Choice C reason: Low birth weight is not a typical complication of GDM, as it is more associated with intrauterine growth restriction (IUGR), which is caused by placental insufficiency. GDM can cause the opposite problem, which is excessive fetal growth.

Choice D reason: Macrosomia is the most common complication of GDM, as it is defined as a birth weight of more than 4,000 grams (8.8 pounds). It is caused by the excess glucose crossing the placenta and stimulating the fetal insulin production, which leads to increased fat deposition and organ enlargement. Macrosomia can increase the risk of birth trauma, shoulder dystocia, and neonatal hypoglycemia.
