Difference between preconception and premarital health care Preconception health care is a health service concept currently adopted in most countries around the world. The goal is to provide health education and preventive health services to women of childbearing age and their families to reduce risk factors that may cause adverse pregnancy outcomes (e.g., miscarriage, preterm birth, stillbirth, fetal growth disorders or delays, congenital malformations, and severe maternal pregnancy complications). Analysis of the reproductive life cycle shows that a woman enters puberty straight through menopause for up to 30 years, and during this long period, if unprotected sex occurs. The possibility of pregnancy is present at any time. Premarital care is limited to the period of preparation for marriage, while preconception care is continuous for decades. The population of preconception care can be divided into two major parts, the basic part of which is the entire population of childbearing age, and the other part is called the relevant population, which refers to the family, friends, classmates, colleagues of women of childbearing age, and especially the spouse or sexual partner of women of childbearing age. Fertility is not only a woman’s business, but also a group of people who may influence the outcome of pregnancy through various ways, ideas, habits and behaviors. This is why women of childbearing age and their associates need knowledge and information about reproductive health, as well as counseling on social adjustment and psychological adjustment. In other words, preconception health care is broader and more comprehensive than premarital health care, and preconception health care is more extensive and social than premarital health care.
