    Correct

    • Regarding listeria infection during pregnancy, what is the fetal case mortality rate?

      Your Answer: 25%

      Explanation:

      Listeria Monocytogenes is a cause of congenital infection. The most common source of the bacteria is food, especially unpasteurised milk. Congenital listeriosis can lead to spontaneous abortions, premature birth and chorioamnionitis. At birth, neonates may present with septicaemia, respiratory distress and inflammatory granulomatosis. The case mortality rate for listeriosis is thought to be between 20-30%.

    Incorrect

    • A 29 year old patient presents due to the sensation of reduced fetal movements (RFM). From what gestation is CTG assessment of RFM advised?

      Your Answer: 18+0 weeks

      Correct Answer: 28+0 weeks

      Explanation:

      The cardiotocograph (CTG) is a continuous tracing of the fetal heart rate used to assess fetal wellbeing. The Doppler effect detects fetal heart motion and allows the interval between successive beats to be measured, thereby allowing a continuous assessment of fetal heart rate. The mother perceives the fetal movement by the 18-20 week of gestation and these increase until the 32 week. A mother should under go CTG if the fetal movements are reduced by the 28 week of gestation.

    Incorrect

    • Which of the following is regarded as the current Gold standard in the diagnosis of Polycystic Ovary Syndrome?

      Your Answer: NICHD

      Correct Answer: Rotterdam

      Explanation:

      The Rotterdam criteria was developed and expanded by the European Society of Human Reproduction and Embryology/American Society for Reproductive Medicine Rotterdam consensus (ESHRE/ASRM) in 2003 and is now the Gold standard in the diagnosis of PCOS. The criteria requires two of three features: anovulation, hyperandrogenism, and polycystic ovaries seen on ultrasound.

      The National Institute of Child Health and Human Development (NICHD) attempted to define PCOS in 1990 but omitted ultrasonographic evidence of polycystic ovaries which is considered to be diagnostic of PCOS.

      The Androgen Excess Society (AES) served to confirm hyperandrogenism as the central event in the development of PCOS.

      The ROME III criteria is used for Irritable Bowel Disease and is therefore not applicable to PCOS.

    Correct

    • A 25-year-old Aboriginal woman at ten weeks of gestation presents with a 2-week history of nausea, vomiting and dizziness. She has not seen any doctor during this illness.

      On examination, she is found to be dehydrated, her heart rate is 135 per minute (sinus tachycardia), blood pressure 96/60 mm of Hg with a postural drop of more than 20 mm of Hg systolic pressure and is unable to tolerate both liquids and solids.Urine contains ketones and blood tests are pending.

      How will you manage this case?

      Your Answer: Give metoclopramide and intravenous normal saline

      Explanation:

      Analysis of presentation shows the patient has developed hyperemesis gravidarum.
      She is in early shock, presented as sinus tachycardia and hypotension, with ketonuria and requires immediate fluid resuscitation and anti-emetics. The first line fluid of choice is administration of normal saline 0.9%, and should avoid giving dextrose containing fluids as they can precipitate encephalopathy and worsens hyponatremia.

      The most appropriate management of a pregnant patient in this situation is administration of metoclopramide as the first line and Ondansetron as second line antiemetic, which are Australian category A and B1 drugs respectively. The following also should be considered and monitored for:
      1. More refractory vomiting.
      2. Failure to improve.
      3. Recurrent hospital admissions.

      Steroids like prednisolone are third line medications which are used in resistant cases of hyperemesis gravidarum after proper consultation.

    Incorrect

    • A 28-year-old woman at 35 weeks gestation who is gravida 2 para 1, presented to the labour and delivery department since she has been having regular, painful contractions over the past 3 hours. Upon interview and history-taking, it was noted that the patient has had no prenatal care during this pregnancy. She also has no chronic medical conditions, and her only surgery was a low transverse caesarean delivery 2 years ago.

      Upon admission, her cervix is 7 cm dilated and 100% effaced with the fetal head at +2 station. Fetal heart rate tracing is category 1.
      Administration of epidural analgesia was performed, and the patient was relieved from pain due to the contractions. There was also rupture of membranes which resulted in bright-red amniotic fluid.

      Further examination was done and her results were:
      Blood pressure is 130/80 mmHg
      Pulse is 112/min

      Which of the following is most likely considered as the cause of the fetal heart rate tracing?

      Your Answer: Intraamniotic infection

      Correct Answer: Fetal blood loss

      Explanation:

      Fetal heart rate tracings (FHR) under category I include all of the following:
      – baseline rate 110– 160 bpm
      – baseline FHR variability moderate
      – accelerations present or absent
      – late or variable decelerations absent
      – early decelerations present or absent

      The onset of fetal bleeding is marked by a tachycardia followed by a bradycardia with intermittent accelerations or decelerations. Small amounts of vaginal bleeding associated with FHR abnormalities should raise the suspicion of fetal haemorrhage. This condition demands prompt delivery and immediate reexpansion of the neonatal blood volume.

    Correct

    • A 53-year-old lady had mild vaginal bleeding for the previous 18 hours following sexual engagement. It's been a year since she had her last menstrual cycle. Her previous cervical screening test was 12 months ago, and everything came back normal. For the past year, she had not engaged in any sexual activity. She wasn't on any hormone replacement treatment at the time.

      Which of the following is the most likely cause of her symptoms?

      Your Answer: Atrophic vaginitis

      Explanation:

      Postmenopausal haemorrhage has started in this patient. Menopause is defined as the permanent cessation of menstruation and fertility that occurs 12 months after the previous menstrual period.

      Atrophic vaginitis caused by oestrogen insufficiency is the most likely reason for this woman’s postmenopausal haemorrhage. It can also induce vaginal dryness and soreness during sexual intercourse.

      Endometrial hyperplasia is unlikely to develop without hormone replacement therapy or oestrogen stimulation of the endometrium.

      Similarly, endometrial cancer is a less likely cause of this patient’s post-menopausal bleeding.

      A year ago, this woman received a normal cervical screening test. Cervical cancer is extremely unlikely to occur. After 12 months of no oestrogen, it’s also unlikely that you’ll have any irregular periods.

    Correct

    • A 23-year-old pregnant woman, in her 19 weeks of pregnancy, presents to your office complaining of increased frequency and urgency along with dysuria.

      Further investigations established the diagnosis of urinary tract infection and the culture results are pending. The patient also mentioned a history of allergic reaction to penicillin which manifest as a rash.

      For treating this patient, which one of the following would be the antibiotic of choice?

      Your Answer: Cephalexin

      Explanation:

      The best antibiotic of choice for empirical treatment of a urinary tract infection (UTI) during pregnancy is cephalexin. Nitrofurantoin and amoxicillin-clavulanate are second and third in-line respectively.
      Patients allergic to penicillin, which is manifested as a rash can also be safely treated with cephalexin. But cephalosporins are not recommended if the presentation of allergic reaction to penicillin was anaphylactic, instead they should be treated with nitrofurantoin.

      NOTE– Asymptomatic bacteriuria, such as >10 to power of 5 colony count in urine culture of an asymptomatic woman in pregnancy, should best be treated with a one week course of antibiotics, followed by confirming the resolution of infection via a urine culture repeated 48 hours after the completion of treatment.

      Amoxicillin without clavulanate is recommended only in cases were the susceptibility of the organism is proven.

      Macrolides like clarithromycin are usually not recommended for the treatment of UTI.

      Aminoglycosides are coming under category D drugs should be avoided during pregnancy, unless there is a severe indication of gram negative sepsis.

      Tetracycline, due to their potential teratogenic effects, are contraindicated in pregnancy.

    Correct

    • A 32-year-old mother with a 9-year-old child is considering having a second child. Her first pregnancy was complicated by puerperal psychosis. Following electroconvulsive therapy (ECT), she promptly recovered and has been well until now. She is in excellent health and her husband has been very supportive. According to patient files, she was noted to be an excellent mother.

      What would be the most appropriate advice?

      Your Answer: There is a 15-20% chance of recurrence of psychosis postpartum.

      Explanation:

      Puerperal psychosis seems to be mainly hereditary and closely associated with bipolar disorder especially the manic type, rather than being a distinct condition with a group of classical symptoms or course. Postpartum psychoses typically have an abrupt onset within 2 weeks of delivery and may have rapid progression of symptoms. Fortunately, it is generally a brief condition and responds well to prompt management. If the condition is threatening the mother and/or baby’s safety, hospital admission is warranted. A patient can present with a wide variety of psychotic symptoms ranging from delusion, passivity phenomenon, catatonia, and hallucinations. While depression and mania may be the predominating features, it is not surprising to see symptoms such as confusion and stupor. Although the rate of incidence is about 1 in 1000 pregnancies, it is seen in about 20% of women who previously had bipolar episodes prior to pregnancy. It has not been shown to be linked with factors such as twin pregnancies, stillbirth, breastfeeding or being a single parent. However, it might be more commonly seen in women who are first-time mothers and pregnancy terminations.

      The risk of recurrence is 20%. Unfortunately, there is no specific treatment guideline but organic causes should first be ruled out. First generation/typical anti-psychotics are often associated with extrapyramidal symptoms. Nowadays, atypical antipsychotics such as risperidone or olanzapine can be used along with lithium which is a mood stabiliser. As of now, there hasn’t been any significant side effects as a result of second generation antipsychotic use in pregnancy. While women are usually advised to stop breast-feeding, it might be unnecessary except if the mother is being treated with lithium which has been reported to cause side effects on the infants in a few instances. ECT is considered to be highly efficacious for all types of postpartum psychosis and may be necessary if the mother’s condition is life-threatening to herself or/and the baby. If untreated, puerperal psychosis might persist for 6 months or even longer.

      The options of saying ‘in view of her age and previous problem, further pregnancies are out of the question’ and so is ‘By all means start another pregnancy and see how she feels about it. If she has misgivings, then have the pregnancy terminated.’ are inappropriate.

      As mentioned earlier, considering there is a 20% chance of recurrence it is not correct to say that since she had good outcomes with her first pregnancy, the risk of recurrence is minimal.

      Anti-psychotics are not recommended to be used routinely both during pregnancy and lactation due to the absence of long-term research on children with intrauterine and breastmilk exposure to the drugs. Hence it is not right to conclude that ‘if she gets pregnant then she should take prophylactic antipsychotics throughout the pregnancy’ as it contradicts current guidelines. Each case should be individualised and the risks compared with the benefits to decide whether anti-psychotics should be given during pregnancy. It is important to obtain informed consent from both the mother and partner with documentation.

      Should the mother deteriorates during the pregnancy that she no longer is capable of making decisions about treatment, then an application for temporary guardianship should be carried out to ensure that she can be continued on the appropriate treatment.

    • Which of the following is the most appropriate for diagnosis of Bacterial Vaginosis (BV)?

      Your Answer: Gardnerella vaginalis wet prep culture

      Correct Answer: Amsel's criteria

      Explanation:

      Diagnosis can be made using the Amsel’s criteria:
      1. Presence of clue cells on microscopic examination (these cells are epithelial cells covered with the bacteria).
      2. Creamy greyish discharge.
      3. Vaginal pH of more than 4.5.
      5. Positive whiff test – release of fishy odour on addition of alkali solution. Other criteria include the nugent score and the Hay/Ison criteria. The Nugent score estimates the relative proportions of bacterial morphotypes to give a score between 0 and 10 (<4 = normal, 4-6 = intermediate, >6 = BV)
      The Hay/Ison criteria
      Grade 1 (Normal): Lactobacillus morphotypes predominate
      Grade 2 (Intermediate): Mixed flora with some Lactobacilli present, but Gardnerella or Mobiluncus morphotypes also present
      Grade 3 (BV): Predominantly Gardnerella and/or Mobiluncus morphotypes. Few or absent Lactobacilli.

    Correct

    • You are asked to assess a patients perineal tear following labour by vaginal delivery. You note a laceration that extends approximately a quarter of the thickness through the external anal sphincter. How would you classify this tear?

      Your Answer: 3a

      Explanation:

      1. First-degree trauma corresponds to lacerations of the skin/vaginal epithelium alone.
      2. Second-degree tears involve perineal muscles and therefore include episiotomies.
      3. Third-degree extensions involve any part of the anal sphincter complex (external and internal sphincters):
      i Less than 50 per cent of the external anal
      sphincter is torn.
      ii More than 50 per cent of the external anal
      sphincter is torn.
      iii Tear involves the internal anal sphincter
      (usually there is complete disruption of the
      external sphincter).
      4. Fourth-degree tears involve injury to the anal sphincter complex extending into the rectal mucosa.

    Correct

    • Regarding fertilization & implantation:

      Your Answer: The sperm head penetrates through the corona radiata & zona pellucida while the tail remains outside

      Explanation:

      During fertilization, a sperm must first fuse with the plasma membrane and then penetrate the female egg cell to fertilize it. Fusing to the egg cell usually causes little problem, whereas penetrating through the egg’s hard shell or extracellular matrix can be more difficult. Therefore, sperm cells go through a process known as the acrosome reaction, which is the reaction that occurs in the acrosome of the sperm as it approaches the egg. The acrosome is a cap-like structure over the anterior half of the sperm’s head. Upon penetration, if all is normally occurring, the process of egg-activation occurs, and the oocyte is said to have become activated. This is thought to be induced by a specific protein phospholipase c zeta. It undergoes its secondary meiotic division, and the two haploid nuclei (paternal and maternal) fuse to form a zygote. To prevent polyspermy and minimize the possibility of producing a triploid zygote, several changes to the egg’s cell membranes render them impenetrable shortly after the first sperm enters the egg.

    • A 23 year old patient presents to the emergency department with sudden onset of severe lower abdominal and pelvic pain. History reveals she normally has regular 28 day cycles but she missed her last period. Past medical history reveals 2 termination of pregnancy procedures in the past 3 years. The most recent one 6 months ago. She smokes 5 cigarettes per day.

      Your Answer: Ectopic pregnancy

      Explanation:

      This patient is most likely to have a ruptured ectopic pregnancy. The history of multiple TOPs suggests her contraceptive methods are not reliable and her missed period is suggestive she may currently be pregnant. There is no temperature or vaginal discharge to suggest PID though this is of course possible as is appendicitis. The last termination was 6 months ago so endometritis is unlikely.

    Correct

    • Hirsutism can be found in all of the following conditions, EXCEPT:

      Your Answer: Patient on oral contraceptive pills

      Explanation:

      Classically, hirsutism has been considered a marker of increased androgen levels in females from increased production of androgens (i.e. testosterone) either by the adrenals or due to an ovarian disease. The ovarian causes for hyperandrogenism are polycystic ovarian syndrome (PCOS) and ovarian tumours. Adrenal causes include Cushing’s syndrome, androgen-producing tumours, and congenital adrenal hyperplasia (CAH), most commonly due to 21-hydroxylase deficiency. Less common causes include the hyperandrogenic-insulin resistant-acanthosis nigricans syndrome (HAIRAN). Hyperprolactinemia by increasing adrenal dehydroepiandrosterone sulphate (DHEA-S) production may cause hirsutism. Androgenic drugs are also an important cause of hirsutism. About 20% of the patients may present with idiopathic hirsutism (IH) with normal androgen levels and ovarian function. The cause of increased hair in these women is thought to be related to disorders in peripheral androgen activity. Onset of IH occurs shortly after puberty with slow progression. PCOS and IH account for 90% of the hirsutism in women. Hirsutism can also occur in some premenopausal women and continue for a few years after menopause. This is due to decrease in ovarian oestrogen secretion with continuous androgen production.

    Incorrect

    • A 50-year-old third-generation Australian woman presents with intermittent lower abdominal pain. An abdominal ultrasound was performed and showed a probable malignancy involving the left ovary. The report suggests that the ovarian lesion may represent a metastatic disease.

      Which one of the following is the most appropriate investigation that will likely show the site of the primary tumour?

      Your Answer: Computed tomography (CT) of the abdomen.

      Correct Answer: Colonoscopy.

      Explanation:

      This woman presents with a metastatic tumour of the ovary. Being from Australia is a hint in this question as the likely site of the primary tumour can vary depending on the country the patient is in and the availability of screening mammography. In underdeveloped countries, breast cancer is usually diagnosed later in life as screening mammography is generally not available, making the most likely site of the primary tumour in the breast. In Japan, where the incidence of stomach cancer is much higher than in western countries, the most likely primary site would be the stomach with a Krukenberg tumour in both ovaries. In Australia, mammographic screening is recommended every other year for all women over the age of 50, and so the most likely primary site would be the colon.

      The most appropriate work-up to find the primary tumour in this patient would be performing a colonoscopy. A computed tomography (CT) of the abdomen may miss a small tumour, and an ultrasound examination would not be able to diagnosis a colon cancer. Mammography would be the correct response in under-developed countries. A lung malignancy would be detectable by chest X-ray, but would rarely cause a metastasis in the ovary.

    • A patient arrives on labour ward she is 37 weeks pregnant. Her last pregnancy ended with delivery via uncomplicated lower segment C-Section 4 years ago. Contractions are 5 minutes apart and on examination the cervix is 5cm dilated. What is the risk of uterine rupture with vaginal delivery?

      Your Answer: 25 per 10,000

      Explanation:

      Consideration of the risk of scar rupture is probably the most important consideration when determining whether delivery should be by elective Caesarean section or by trial of vaginal delivery.
      Most published studies do not differentiate between scar dehiscence and rupture, however, analysis of observational and comparative studies indicates that the excess risk of uterine rupture following trial of labour compared with women undergoing repeat elective Caesarean section is considerably lower than 1 per cent (25/10000); indeed, some studies do not demonstrate any increased risk.

      Your Answer: Amniocentesis

      Correct Answer: Chorionic Villous Sampling

      Explanation:

      Chorion villus sampling is an invasive procedure which aims to collect the rapidly dividing cells in the placenta.

    Correct

    • A 25-year-old woman presents to your clinic for her routine annual check-up and Pap smear. She has a single partner who uses condoms during contraception. Her menstrual cycle is regular and around four weeks long. Her last menstrual period was 2 weeks ago. She is otherwise healthy with no symptoms suggesting a problem with her genital tract. Per vaginal examination is performed revealing a 4 cm cystic swelling in the right ovary. What would be the best next step of management?

      Your Answer: See her again in six weeks and arrange an ultrasound examination if the cyst is still present.

      Explanation:

      Because of the high possibility of spontaneous resolution and the fact that if the cystic mass was verified ultrasonically, a conservative policy would almost probably be proposed for at least another six weeks, an ultrasound examination is not necessary at this time. If the cyst is still present at the six-week check, an ultrasound examination is required, as it is likely that the cyst is a benign tumour or possibly endometriosis. It’s quite improbable that it’s cancer.
      Additional tests, such as computed tomography (CT) examination and potentially surgical removal or drainage, may be required in the future, although not at this time.
      This cyst in a young lady is almost probably of physiological origin, especially given its size. The woman should be informed, but a follow-up examination is required. The most suitable next action is to return in six weeks, as the cyst is most likely physiologic and will most likely dissipate naturally by then. The following appointment should not take place during the same menstrual cycle.

    Incorrect

    • How long does involution of the uterus take after parturition?

      Your Answer: 1-2 weeks

      Correct Answer: 4-6 weeks

      Explanation:

      In the period immediately after the delivery of the placenta, known as the puerperium, the female reproductive system begins to undergo some physiological changes to return to a non-pregnant state. One of these changes is uterine involution. The myometrium contracts, constricting blood vessels which impedes blood flow. It is thought that the uterine tissues then undergo apoptosis and autophagy. It takes about 4-6 weeks for the uterus to decrease is size from about 1 kg to 60 grams.

      Which of the following best characterizes the incontinence she's dealing with?

      Your Answer:

      Correct Answer: Stress incontinence

      Explanation:

      Overflow incontinence typically presents with continuous urinary leakage or dribbling in the setting of incomplete bladder emptying. Associated symptoms can include weak or intermittent urinary stream, hesitancy, frequency, and nocturia. When the bladder is very full, stress leakage can occur or low-amplitude bladder contractions can be triggered resulting in symptoms similar to stress or urgency incontinence.

      Women with urgency incontinence experience the urge to void immediately preceding or accompanied by involuntary leakage of urine

      Individuals with stress incontinence have involuntary leakage of urine that occurs with increases in intraabdominal pressure (e.g., with exertion, sneezing, coughing, laughing) in the absence of a bladder contraction.

      Your Answer:

      Correct Answer: Measuring absorption from two different XRAY beams with different energy peaks at the same site

      Explanation:

      DEXA works by passing two low dose XRAY beams with different energy peaks at the patient’s bone. Some of the XRAY radiation will be absorbed (the greater the density the greater the absorption) whilst some will pass through to a detector. Soft tissue absorption is subtracted out and the BMD can be determined from the absorption of each beam. It is important to realise that two beams are used at each site when measuring bone density (hence ‘dual’). Although two sites are typically used (spine and femoral neck) when measuring bone density this is not why the term dual is used Computer analysis of multiple X-ray beams taken from different angles and geographical digital processing are features of CT scanning

    Incorrect

    • A 20-year-old nulligravid woman comes to the office for a routine checkup, as she is concerned about having gained 4.5 kg over the last year. She believes that the gain is related to her oral contraceptive pills. 

      Patient takes low-dose ethinyl estradiol
      orethindrone daily. Prior to starting the pills, she had regular but heavy periods lasting for 4-5 days.  Patient used to miss her school every month, on the first day of her period, due to severe cramping. Her pain symptoms resolved 3 months after starting the pills and she takes no other medications.  Patient's coitarche was at the age of 18 and she has had 2 partners since then. Patient and her current partner use condoms inconsistently. 

      On examination her vital signs are normal, with a BMI of 27 kg/m2 and physical examination is unremarkable. 

      Among the following which is the most appropriate advice for this patient?

      Your Answer:

      Correct Answer: Reassure that the weight gain is not related to combined OCPs

      Explanation:

      Breakthrough bleeding, breast tenderness, nausea, bloating, amenorrhea, hypertension, venous thromboembolic disease, increased risk of cervical cancer with decreased risk of ovarian & endometrial cancer, liver disorders like hepatic adenoma and increase in triglycerides due to estrogen component are the common side effects & risks of using combination oral contraceptives.

      Patient in the given case mentioned symptoms of primary dysmenorrhea, which is recurrent lower abdominal pain associated with menstruation. Combination estrogen-progestin oral contraceptive pills (OCPs) are considered as the first-line treatment for dysmenorrhea in sexually active patients as OCPs help to reduce pain by thinning the endometrial lining, reducing prostaglandin release and by decreasing uterine contractions.
      Nausea, bloating and breast tenderness, are considered as the early side effects of OCPs and will usually improve with continued use. The most common side effect is breakthrough bleeding which is usually associated with lower estrogen doses and other adverse effects caused by the pills include hypertension, increased risk of cervical cancer and venous thromboembolism. Although common perception considers weight gain as a side effect, several studies have shown that no significant weight gain is associated with OCPs, particularly with low-dose formulations.  Considering this, the patient should be reassured that her weight gain is not associated with regular use of OCPs.

      In patients who are not sexually active, nonsteroidal anti-inflammatory drugs are considered as the first-line treatment for primary dysmenorrhea. As stopping contraception will increase this Patient’s risk of unintended pregnancy this is not advisable to her.

      Switching the patient to a copper intrauterine device (IUD) will decrease systemic side effects, but as its inflammatory reaction in the uterus may increase pain symptoms, copper IUD is not recommended for patients with dysmenorrhea.

      As Medroxyprogesterone will increase body fat and decrease lean muscle mass resulting in weight gain is not a good option for this patient. Also medroxyprogesterone due to its risk of significant loss of bone mineral density, is not recommended for adolescents or young women. So it can be used in this age group only if other options are unacceptable.

      Presence of estrogen component is the main reason behind the side effects of combination OCPs. Progesterone-only pills have relatively fewer side effects but as they do not inhibit ovulation, they are less effective for treating dysmenorrhea and for contraception.

      Combination oral contraceptive pills are the first-line therapy for primary dysmenorrhea in sexually active patients.  Its side effects include breakthrough bleeding, hypertension, and increased risk of venous thromboembolism. Researches proves that weight gain is usually not an adverse effect of OCPs.

      Your Answer:

      Correct Answer: 21-hydroxylase

      Explanation:

      Congenital Adrenal Hyperplasia leads to the virilization of the foetus. It occurs due to an enzyme deficiency in the corticosteroid production pathway i.e. 21-hydroxylase which converts progesterone to deoxycorticosterone. The reduced levels of corticosteroids results in the negative feedback loop that leads to adrenal hyperplasia.

      Explanation:

      There are several risk factors for gestational diabetes:
      Increasing age
      – Certain ethnic groups (Asian, African Americans, Hispanic/Latino Americans and Pima Indians)
      – High BMI before pregnancy (three-fold risk for obese women compared to non-obese women)
      – Smoking doubles the risk of GDM
      – Change in weight between pregnancies – an inter-pregnancy gain of more than three units (of BMI) doubles the risk of GDM
      – Short interval between pregnancies
      – Previous unexplained stillbirth
      – Previous macrosomia
      – Family history of type 2 diabetes or GDM – more relevant in nulliparous than parous women

      High polyunsaturated fat intake has been shown in some studies to be protective against gestational diabetes. Physical activity is also thought to be effective.
