Q

Why does excess body fat decrease fertility?

A
  • higher estrogen, leptin, androgen (males and females and lower testosterone in males)
  • menstrual cycle irregularity (30-47%)
  • reduced sperm production and erectyle disfunction

Q

Why does inadequate body fat decrease fertility?

A
  • Weight loss exceeding 10-15% decreases estrogen, LH and FSH = amenorrhea, anovulatory cycles, short/absent luteal phases
  • Critical level of body fat (BMI>20kg/m2) REQUIRED to trigger and sustain normal reproductive functions
  • Low levels of body fat during adolescence delays onset of menstruation and reduces fertility
  • LT consequences of undernutrition revealed during famine (Dutch famine 194/5)

Q

Physiological changes during pregnancy

A
  • Weight gain: 12-15kg

  • Cardiovascular: increase in HR & BP
  • Respiratory: difficulty breathing due to pressure on lungs
  • Hematological: Increase in plasma volume and decrease in hemoglobin (RBC), iron deficiency
  • Gastrointestinal: Decreased GI motility from elevated progesterone relaxing smooth muscle and pressure on colon and rectum causing constipation (also due to iron supplements).

Q

Human Placental Lactogen (HPL)

A

Hormone produced by plancenta when pregnant.
- Decreases insulin sensitivity and glucose utilizations = raises blood glucose level for adequate fetal nutrition.
- Increases gluconeogenesis to increase glucose for availability for fetus
- Chronic hypoglycemia leads to rise in HPL.
- HPL includes lipolysis, release of FFA to fuel mother. Ketones formed by FFA can be used for fetus as well as glucose.
*these functions help to support fetal nutrition even in the case of malnutrition

64
Q

Gestational diabetes, complications for the baby

A
  • High maternal blood glucose exposes the fetus to higher glucose (placental diffusion facilitated by GLUT3 carriers) -> Increased fetal levels of insulin (insulin can not cross the placenta)

    high risk of getting type 2 diabetes later in life due to genetics (T2DM)
65
Q

68
Q

Large for gestational age (LGA)

“fetal overgrowth”
- above 90th percentile for agr
macrosomia (>4kg)
- delivery of infanct >4kg = increased risk of cecearan delivery, fetal hypoglycemia and shoulder dystocia

A

yes

76
Q

How does Toxoplasmosis occour?

A

81
Q

un necessary iron supplement use may lead to?

A
  • GI diabetes
  • oxidative stress
  • preeclampsia (high BP, fluid retention)
82
Q

What is the recommended weight gain for pre-pregnancy healthy weight women in a twin pregnancy?

A

is between 17-25 kg

83
Q

How much extra energy (dietary intake) is required per day above a singleton pregnancy for a woman carrying twins?

      Helps mother return to pre-pregnancy weight more rapidly
121
Q

What are the 10 specific steps to successful breast feeding?

A
  1. Policy communicated to all staff
    1. Train in skills to implement this policy
    2. Inform about benefits
    3. Helping mothers to initiate within first hour
    4. Showing mothers how to maintain lactation even when separated from infant
    5. Don’t feed water or food
    6. Allow to be together 24h day
    7. Encourage breast feed on demand
    8. No teats or pacifiers
      Refer to support groups upon discharge from hospital
  2. Refer mothers to support groups on hospital discharge
122
Q

Can alcohol cross easily into breast milk and to the baby?

A

yes - can remain in milk for several hours (Depends on weight and metabolism)

123
Q

Adverse effects of drinking alcohol while breast feeding?

A

Limits oxytocin causing a delay in ‘let down’ of milk and decreasing milk production.
Alcohol may remain in breast milk for several hours
Effects baby’s sleep patterns and behavior causing irritability and not feed properly.

A

greater protein content (increases overweight and obesity) *may be long term effects
formula: 2.2g / 100 cal
breast milk: 1.5g / cal

proposed to keep protien to a min of 0.45g /100kj

Lactose
- lactose intollerance is rare in infants
- primary lactase enzyme deficiency (uncommon before 2)
- Secondary lactase enzyme deficiency is more common but ST. Small bowel injury from non-IgE-mediated cows milk allergy or viral gastroenteritis
- Lactose free formula e.g. soy - contain corn-syrup as a sub
- Lactose and glucose polymers = preffered cho in formula
*Sucrose and fructose are not recommended

128

Effects of babies born to mothers from dutch fammine in their adulthood

A

More susceptible to
- Diabetes
- Obesity
- Cardiovascular disease
- Protein in urine disease (Microalbuminuria)

also epigenetic changes - them and their offspring were SMALLER

134
Q

Barker hypothesis
Fetal origins of adult disease (FOAD) / developmental origins of health and disease (DOHaD)

A

The fetal origins hypothesis states that:
Fetal under nutrition mid-late gestation which leads to disproportionate fetal growth, programmes later coronary heart disease.

  • lower birth weight - more likely to have Coronary heart disease and impaired glucose tollerance -> diabetes (T2DM)
135
Q

Infertility influences

A

Health: weight loss struggles
Health care: “white space” in clinic.
Cultural: blessings / permission from village and family
Spiritual: repent to god. “meat to me”
Socio-economic: cost of fertility treatment (ARTS)

136
Q

Pacific Strategies and recommendations

A

Family: open discussions with eachother
Community: more suppourtive e.g. social media groups
School: educated in curriculum (pacific females and PCOS
Service providers: need to be culturally appropriate when addressing and understanding pacific issues with infertility as is “white space” dominant
Research: need more around pacific by pacific for pacific

137
Q

Retinoc acid syndrome

A

birth defects from excess mounts of Retinol or retinoic acid (vitamin A) in maternal diet (>10,000IU/day or 3,000RE/day)

  • small, missing ears and ear canals
  • cv, craniofacial, small head (microcephaly) , thymus dysfunction
138
Q

Vitamin D defficency

A

Maternal: gestational dibetes and pre-eclamsia (High bp and protein in urine)
Infant: 3 times more likely to have tooth decay by 6 years old, low birth weight, dental decay, acute respiratory infections
