Teenage pregnancy and premarital sex can pose health risks for both mother and baby. Babies born to teenage mothers have an increased risk of low birth weight, premature birth, and developmental issues. Teen mothers also have higher risks of social and economic problems like lower educational attainment and income levels. While rates of teen pregnancy have declined in Canada and the US due to better access to contraception and sex education, it remains a complex issue with medical, social and moral dimensions. Abstinence, contraceptive use, and comprehensive sex education are discussed as ways to further reduce unintended teen pregnancies.
