Insights

Neural tube defects (NTDs) are a significant cause of infant mortality. Folic acid supplementation is recommended for women of childbearing age to prevent NTDs, yet awareness and intake remain challenges.

Area of Science:

  • Public Health
  • Obstetrics and Gynecology
  • Genetics

Background:

  • Neural tube defects (NTDs) are a major contributor to infant mortality.
  • Most NTDs result from multifactorial causes, involving both genetic and environmental factors.
  • Folic acid demonstrates a protective effect against NTD occurrence and recurrence.

Purpose of the Study:

  • To highlight the importance of folic acid in preventing neural tube defects.
  • To underscore the public health initiatives for folic acid fortification and supplementation.
  • To identify persistent challenges in ensuring adequate folic acid intake among women of childbearing age.

Main Methods:

  • Review of existing literature on neural tube defects and folic acid.
  • Analysis of public health recommendations and fortification policies in the United States.
  • Identification of barriers to adequate folic acid consumption in women of childbearing age.

Main Results:

  • Folic acid fortification of grain products is standard in the US.
  • A daily intake of 0.4 mg of folic acid is recommended for women who could become pregnant.
  • Despite these measures, suboptimal folic acid levels persist in some women.

Conclusions:

  • Continued education is crucial to improve folic acid consumption among women of childbearing age.
  • Addressing knowledge gaps and accessibility issues is key to maximizing the benefits of folic acid.
  • Public health strategies must evolve to overcome challenges in achieving adequate folic acid intake for NTD prevention.

Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Preventive Healthcare Services01:30

Preventive Healthcare Services

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:
Levels of Health Promotion and Illness Prevention01:26

Levels of Health Promotion and Illness Prevention

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...
Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...
