Rates of teenage pregnancies are higher in societies where it is traditional for girls to marry young and where they are encouraged to bear children as soon as they are able. For example, in some sub-Saharan African countries, early pregnancy is often seen as a blessing because it is proof of the young woman's fertility.  Countries where teenage marriages are common experience higher levels of teenage pregnancies. In the Indian subcontinent, early marriage and pregnancy is more common in traditional rural communities than in cities.  The lack of education on safe sex, whether it is from parents, schools, or otherwise, is a cause of teenage pregnancy. Many teenagers are not taught about methods of birth control and how to deal with peers who pressure them into having sex before they are ready. Many pregnant teenagers do not have any cognition of the central facts of sexuality. 
There has been a very large amount of research on the causes of health inequalities in the world but less evidence on how to reduce, tackle or bring it to a stop. The major aim of tackling health inequalities is to build a more equal distribution of health between the social groups so that every individual gets to benefits. Health inequalities were known in the UK after the Black Report was published. The Black Report showed that there had been an improvement in health across social classes with the help of National Health Scheme (NHS). It is clear that the simplest way to tackle health inequalities is to improve on the social determinants of health in which the World Health Organization (WHO) defined the social determinants of health as 'the condition in which people are born, grow, adapt, work and age including the health system. The figure below shows a summary of these conditions as proposed by Dahlgren and Whitehead (1991).
A lot of it must come down to how young girls are overly sexualized by the media, and put under pressure to become sexually active at a young age. Education also puts too much emphasis on just girls, and reinforces the fact that it is the mothers that are usually blamed for teen pregnancy while the fathers often take no responsibility and get away with it. Young men need to know that they can’t behave in this way, and understand the pressures of becoming a father, while girls need to become more assertive and be able to demand the use of contraception even if they’re drunk and their partner doesn’t want to use it.
