MATERNAL AND CHILD NUTRITION Arifa Sultana Lecturer Daffodil International University  CHAPTER -1  NUTRITION AND FERTILITY;  NUTRITION DURING THE PRECONCEPTION PERIOD;  RECOMMENDED DIETARY INTAKE FOR PRECONCEPTION NUTRITIONAL STATUS;  NUTRITION CARE PROCESS RELATED TO THE PRECONCEPTION PERIOD  Medical conditions that affect fertility several medical conditions can cause infertility problems, such as:  1. Diabetes One of the health issues affecting fertility is diabetes. Diabetes occurs when the pancreas doesn’t produce enough insulin, commonly referred to as type 2 diabetes. On the other hand, if the pancreas doesn’t produce insulin at all, this condition is known as type 1 diabetes. Diabetes can cause menstrual disorders, changes in menstrual rhythm, and impact pregnancy success. Women with diabetes are more prone to infections and damage to reproductive organs, especially the fallopian tubes. High blood glucose levels can lead to miscarriages or birth defects in the fetus. Excessive glucose and nutrients during fetal development can result in macrosomia (large baby syndrome). Diabetes can also lower sexual desire (libido) due to fatigue, depression, and anxiety, which can reduce sexual desire. Moreover, natural vaginal lubrication is less common in people with diabetes, leading to discomfort and pain during intercourse.  2. Thyroid Disorders Thyroid disorders are another health issue that can affect fertility. Thyroid disorders cause imbalances in hormone levels. Those with excessive thyroid hormones can develop hyperthyroidism, while insufficient thyroid hormone levels can lead to hypothyroidism. Both hypothyroidism and hyperthyroidism are conditions that can impact fertility in both men and women.  3. Celiac Disease Celiac disease is a genetic autoimmune condition. This condition is triggered by consuming gluten. Eating gluten can trigger an immune response in those with celiac disease. Celiac disease is considered one of the causes of unexplained fertility issues. However, according to a study published in the journal Gastroenterology, celiac disease does not significantly increase the likelihood of fertility problems. The research found that most women with celiac disease do not have an increased risk of fertility issues  4. Polycystic Ovary Syndrome (PCOS) PCOS is one of the most common causes of fertility problems in women of reproductive age. PCOS occurs when a woman experiences disruptions in the ovulation cycle, typically characterized by irregular menstrual cycles. Polycystic ovary syndrome is caused by hormonal imbalances that occur in women of childbearing age.  5. Endometriosis Endometriosis can also be one of the health conditions that affect fertility. This condition is a disease of the female reproductive system, often referred to as a chocolate cyst. A chocolate cyst causes tissue similar to the endometrial lining to grow outside its usual location. This condition can lead to fertility issues, making it difficult for women with endometriosis to conceive. These are some health problems that can disrupt fertility. If you or your partner experience any of them, consult a doctor immediately.  Recommended Dietary Intake for Preconception Nutritional Status 1. Folic Acid: 400-800 mcg daily to prevent neural tube defects. 2. Iron: Adequate iron stores are necessary to prevent anemia and support a healthy pregnancy. 3. Calcium: 1000 mg daily to support bone health. 4. Vitamin D: 600 IU daily to enhance calcium absorption. 5. Omega-3 Fatty Acids: Essential for brain development and reducing inflammation. 6. B Vitamins: Important for energy production and reducing homocysteine levels. 7. Zinc: Vital for immune function and cell division. 8. Iodine: Essential for thyroid function, which regulates metabolism and development. 9. Protein: Necessary for tissue growth and repair. 10.Antioxidants: Vitamins C and E, selenium, and beta-carotene to protect cells from damage. A balanced diet should include a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats. Nutrition Care Process Related to the Preconception Period The Nutrition Care Process (NCP) involves a systematic approach to providing high-quality nutrition care. It includes four steps: 1.Nutrition Assessment: 1. Collecting and interpreting relevant data (dietary intake, medical history, biochemical data, and anthropometric measurements). 2. Identifying potential nutritional deficiencies or excesses. 2.Nutrition Diagnosis: 1. Identifying and labeling nutrition problems based on assessment data. 2. Examples: Inadequate folic acid intake, iron deficiency, or excessive caffeine consumption. 3.Nutrition Intervention: 1. Planning and implementing tailored nutrition strategies to address the diagnosed problems. 2. Examples: Prescribing folic acid supplements, increasing iron-rich foods, reducing caffeine intake, and providing nutrition education. 4.Nutrition Monitoring and Evaluation: 1. Tracking the individual’s progress and evaluating the effectiveness of the intervention. 2. Adjusting the nutrition care plan as needed based on follow-up assessments  PRACTICAL TIPS FOR PRECONCEPTION NUTRITION Start Early: Aim to improve nutrition at least three months before trying to conceive. Balanced Diet: Include a variety of nutrient-dense foods to cover all essential nutrients. Avoid Harmful Substances: Limit or avoid alcohol, caffeine, and foods high in trans fats and added sugars. Healthy Weight: Aim for a healthy body weight through balanced diet and physical activity. Hydration: Ensure adequate fluid intake, mainly through water. Prenatal Vitamins: Consider taking a prenatal vitamin supplement that includes folic acid, iron, and other essential nutrients. Improving nutritional status before conception can support fertility and help ensure a healthy pregnancy and baby.  HORMONES INVOLVED IN THE REGULATION OF MALE AND FEMALE FERTILITY PROCESSES  Gonadotropin-Releasing Hormone (GnRH)  Source: Hypothalamus  Effects: Stimulates the anterior pituitary gland to secrete FSH and LH, which are crucial for regulating the reproductive processes in both males and females.  Follicle-Stimulating Hormone (FSH)  Source: Anterior Pituitary Gland  Effects: In females, FSH promotes the growth and maturation of ovarian follicles. In males, it stimulates spermatogenesis by acting on the Sertoli cells in the testes.  Luteinizing Hormone (LH)  Source: Anterior Pituitary Gland  Effects: In females, LH triggers ovulation and stimulates the formation of the corpus luteum, which produces progesterone. In males, it stimulates the Leydig cells to produce testosterone.  Estrogen  Source: Ovaries (specifically the follicles)  Effects: In females, estrogen is responsible for the development of secondary sexual characteristics, regulation of the menstrual cycle, and preparation of the endometrium for potential pregnancy. In males, it helps regulate certain functions of the reproductive system, although its role is less prominent compared to females.  Progesterone  Source: Corpus Luteum (in the ovaries)  Effects: Prepares the endometrium for implantation of a fertilized egg and maintains pregnancy. It also inhibits the release of further eggs during the menstrual cycle.  Testosterone  Source: Testes (Leydig cells)  Effects: In males, testosterone is crucial for the development of secondary sexual characteristics, spermatogenesis, and libido. In females, it is produced in smaller amounts by the ovaries and adrenal glands and plays a role in ovarian function and libido. Nutrition-related factors play a significant role in the regulation of fertility in both females and males. Body Fat Content Females Low Body Fat: Can lead to amenorrhea (absence of menstruation) and anovulation (absence of ovulation), resulting in reduced fertility. High Body Fat: Associated with conditions like polycystic ovary syndrome (PCOS) and insulin resistance, which can negatively affect ovulation and menstrual regularity. Males Low Body Fat: May result in decreased sperm production and quality. High Body Fat: Linked to lower testosterone levels, reduced sperm count, and decreased sperm motility. Nutrition-related factors Iron Status Females Iron Deficiency: Can lead to anemia, which may cause irregular menstrual cycles and anovulation, thereby affecting fertility. Proper iron levels are crucial for healthy ovarian function and egg quality. Iron Overload: Less common but can potentially cause damage to reproductive organs. Males Iron Deficiency: Can affect sperm quality and motility, impacting fertility. Iron Overload: Associated with conditions like hemochromatosis, which can lead to testicular dysfunction and reduced sperm production. Nutrition-related factors Alcohol Intake Females Excessive Alcohol Intake: Can disrupt menstrual cycles, leading to anovulation and irregular periods. It may also affect hormone levels and ovarian reserve, impacting fertility. Moderate Alcohol Intake: The effects are less clear, but it is generally recommended to limit alcohol consumption when trying to conceive. Males Excessive Alcohol Intake: Linked to decreased testosterone levels, impaired sperm production, and poor sperm quality. Chronic alcohol use can lead to testicular atrophy and reduced libido. Moderate Alcohol Intake: May have less pronounced effects, but it is advisable to limit consumption for optimal reproductive health.  RELATIONSHIPS BETWEEN NUTRIENT INTAKE AND NUTRITIONAL STATUS 1. Folate/Folic Acid Nutrient Intake: Adequate intake of folate or folic acid supplements before conception and during early pregnancy. Nutritional Status: Folate status is crucial for DNA synthesis, repair, and methylation. Outcome of Pregnancy: Reduces the risk of neural tube defects (NTDs) in the developing fetus. Women with sufficient folate levels have a lower risk of NTDs such as spina bifida and anencephaly in their babies. 2. Iron Nutrient Intake: Adequate iron intake through diet or supplements. Nutritional Status: Maintains healthy hemoglobin levels and prevents anemia. Outcome of Pregnancy: Reduces the risk of preterm birth and low birth weight. Proper iron levels support the increased blood volume and oxygen transport needed during pregnancy, promoting fetal growth and development.  RELATIONSHIPS BETWEEN NUTRIENT INTAKE AND NUTRITIONAL STATUS 3. Omega-3 Fatty Acids Nutrient Intake: Consumption of omega-3 fatty acids, particularly DHA (docosahexaenoic acid), from sources like fish or supplements. Nutritional Status: Supports brain and eye development. Outcome of Pregnancy: Associated with better cognitive and visual development in the fetus. Adequate omega-3 intake is linked to a reduced risk of preterm birth and may support longer gestation periods. 4. Vitamin D Nutrient Intake: Adequate intake of vitamin D through sunlight exposure, diet, or supplements. Nutritional Status: Essential for calcium absorption and bone health. Outcome of Pregnancy: Reduces the risk of preeclampsia, gestational diabetes, and low birth weight. Proper vitamin D levels support fetal skeletal development and may reduce complications during pregnancy. Learning outcome : Learning Objectives After studying the materials in this chapter, you should be able to:. 1.
