About six months before conception, undergo a comprehensive gynecological examination and consult your doctor about pregnancy-related matters. If using oral contraceptives, discontinue them six months prior to trying to conceive and switch to barrier methods. If you have had an abortion, wait at least six months before attempting pregnancy.
Additionally, during the six months preceding pregnancy, follow the same precautions as in early pregnancy: avoid febrile illnesses and viral infections, minimize exposure to radiation and chemical substances, refrain from dieting, ensure adequate nutritional intake through diet, and maintain mental relaxation with a positive mindset to welcome the new life.Take your basal body temperature daily before getting out of bed in the morning and record it. This provides a comprehensive understanding of your ovulation patterns and reproductive endocrine function, enabling more accurate identification of your fertile window.
Preconception Rubella Vaccination
Rubella is an acute infectious disease caused by the rubella virus. If a pregnant woman contracts rubella within the first three months of pregnancy, the virus can infect the fetus through the placenta. Rubella can occur year-round, with higher incidence in summer. Infection within the first two months of pregnancy results in a 100% rate of fetal abnormalities; infection after two months carries a 26% risk;and 4% for infections after 6 months. Rubella incidence primarily depends on the immune status of women of childbearing age and the prevalence of rubella. Protective immunity is achieved only when a pregnant woman's rubella antibody titer exceeds 1:20. Epidemiological surveys indicate that while most women of childbearing age in China test positive for rubella antibodies, few reach protective levels.
Prevention is key to avoiding rubella's harm to pregnant women and fetuses. Administering the live rubella vaccine to women of childbearing age provides direct immune protection. Post-vaccination, antibody seroconversion exceeds 95% with over 90% protection. However, pregnancy should be avoided for 3 months after vaccination. A single dose provides approximately 10 years of protection with no adverse reactions, ensuring safety and efficacy.
Timely Folic Acid Supplementation Before Pregnancy
Neural tube defects constitute a severe category of birth defects, accounting for approximately one-third of all congenital abnormalities. Medical research indicates that folic acid supplementation among women of childbearing age can prevent fetal neural tube defects. Folic acid, a water-soluble vitamin, is abundant in animal liver, kidneys, green vegetables, potatoes, and wheat bran, with leafy greens being the richest source.However, folic acid is heat-sensitive and loses about half its content during processing and storage, leading to deficiency in the human body. Currently, approximately 30% of women of childbearing age in China have insufficient folic acid levels. Pregnant women require even more folic acid, making deficiency more severe in this group.
Pregnant women require 0.4 milligrams of folic acid daily, yet dietary intake typically provides only 0.05 milligrams. Folic acid supplements offer convenient administration, meeting the increased needs of both mother and fetus during pregnancy without relying on dietary intake. This makes supplementation an appropriate method for preventing neural tube defects.
Supplementation should begin at least one month before planned conception, with one tablet taken daily. Continue until the end of the third month of pregnancy. Missed doses do not require supplementation. Taking folic acid supplements not only prevents fetal neural tube defects but also offers specific benefits against miscarriage, intrauterine growth restriction, and maternal anemia.
Iodine Supplementation Before and During Pregnancy
Iodine is an essential trace element that the human body cannot synthesize on its own. It is a primary component of thyroid hormone, which is crucial for metabolic activity and growth and development. Iodine is particularly vital for pregnant women and fetuses,It promotes cellular growth in fetuses and infants, particularly brain cell development. Iodine in nature enters the body through food, water, and air. The daily physiological requirement for iodine ranges from 100 to 200 micrograms, with a minimum of 50 micrograms essential to prevent iodine deficiency disorders.
Consuming certified iodized salt is an effective measure to prevent iodine deficiency disorders. However, due to certain issues in the distribution of iodized salt and common errors in daily cooking methods, iodine deficiency disorders still warrant our full attention.Iodized salt should be purchased fresh and consumed promptly. Avoid prolonged storage. Store in a covered container away from sunlight and moisture. Secure the bag opening with a string and keep in a cool, shaded place. Do not use salt that has been fried in oil. Add salt only after the food is fully cooked, or add it just before removing the dish from the stove.
Pregnant women require higher iodine intake due to dual maternal and fetal needs. Regularly consume seaweed, jellyfish, shrimp, oysters, yellow croaker, seaweed, dried shrimp, laver, and soy products to supplement iodine.
