Early detection allows for antenatal management for better neonatal outcomes. Your patient is 32 weeks gestation, gravida 5 para 4 and after a routine ultrasound she is told her baby is very small and has IUGR. She asks you what causes this and you tell her:
Infection
Previous preterm birth
Utero-placental insufficiency
Chronic hypertension
The Correct Answer is C
Choice A reason: Infection is not a common cause of IUGR, as most infections do not cross the placenta and affect the fetal growth. However, some infections such as cytomegalovirus, rubella, or toxoplasmosis can cause congenital anomalies and IUGR.
Choice B reason: Previous preterm birth is not a direct cause of IUGR, as it does not affect the current pregnancy. However, it may indicate an underlying maternal or fetal condition that could increase the risk of IUGR, such as cervical incompetence, placental abruption, or preeclampsia.
Choice C reason: Utero-placental insufficiency is the most common cause of IUGR, as it reduces the blood flow and oxygen delivery to the fetus. It can result from maternal factors such as hypertension, diabetes, smoking, or drug abuse, or from placental factors such as placenta previa, placental infarction, or cord compression.
Choice D reason: Chronic hypertension is a risk factor for IUGR, as it can lead to utero-placental insufficiency and fetal hypoxia. However, it is not the only cause of IUGR, as other factors can also affect the placental function and fetal growth.

Correct Answer is D
Explanation
Choice A reason: None of the above is incorrect because the other choices are not true statements about the overall number of cases of STIs.
Choice B reason: Staying about the same is incorrect because the overall number of cases of STIs is not constant. According to the World Health Organization, more than 1 million STIs are acquired every day worldwide.
Choice C reason: Going down is incorrect because the overall number of cases of STIs is not decreasing. On the contrary, some STIs such as syphilis, gonorrhea, and chlamydia are resurging in many regions due to factors such as antimicrobial resistance, lack of access to prevention and treatment services, and stigma.
Choice D reason: Rising is correct because the overall number of cases of STIs is increasing globally. The World Health Organization estimates that there were 376 million new cases of four curable STIs (chlamydia, gonorrhea, syphilis, and trichomoniasis) in 2016, up from 357 million in 2012. Additionally, there are millions of cases of incurable STIs such as herpes, HPV, and HIV that affect the health and well-being of people worldwide.
