Health Promotion Flashcards
what is public health?
‘the art and science of preventing disease prolonging life and promoting health trough the organized efforts of society’
It seeks to identify risks to health and find the best way to minimize them, in order to give everyone the best chance of leading a healthy life
what is the role of the midwife in public health?
Good public advice is a fundamental part of a midwife’s role. Midwives need to promote family-centred care by meaningful conversations with women around healthy lifestyle choices in pregnancy, making every contact count. The small changes that a woman makes in her lifestyle choices will increase her chances of achieving a healthy pregnancy birth and baby.
what is poverty?
‘… not being able to heat your home, pay the bills or buy the essentials for you children. It means waking up every day facing insecurity, uncertainty and impossible decisions about money.”
Poverty is a risk factor for disease and people living in poverty are more likely to have multiple morbidities and find more difficult to self-manage.
‘… the biggest driver for poor mental health’
child in poverty are more likely to what?
- Die in the first year of life
- Have a low birth weight
- Be formula fed
- Become overweight
Suffer from asthma
what is the child poverty scotland act’s aim?

Social exclusion
- Anxiety and stress
what is the impact of child poverty on health and wellbeing?
- Poor living conditions
- Unhealthy diet
Substance misuse
- Unhealthy diet
what are the benefits to referral to financial inclusion?
- Ensures families are receiving income maximization
- Debt management
- Advice on household energy suppliers, employability and training
- Help mums access sure start maternity grants and healthy start scheme and secure financial entitlements such as child benefit
- Promote people supporting each other
Neonatal expenses to assist with the challenges of sick babies in hospital.
what is the responsibility of midwives in relation to financial inclusion?

- Ensure more widely known access availability of help
Refer any women, not only those on low income, the scheme is open to all families.
- Ensure more widely known access availability of help
what is financial wellbeing?
‘feeling secure and in control. Its knowing you can pay bills today. Can deal with the unexpected and are on track for healthier financial future.’
how do you calculate units in alcoholic drinks?
volume (ml) divided by 1000 x %alcohol by volume
what does one unit of alcohol equal?
8g pure alcohol
what does the average adult women drink per week?
- Adult women drink on average 8.6 units/week. The UK Chief Medical Officer guidelines classify low risk drinking as less than 14 units a week.
what percentage of women drink above low risk level of alcohol?
- Almost 2 out of 10 adult women (16%) drink above this low risk level of 14 units a week
- A little bit more than 1 in 10 women (11.6%) had high scores in the AUDIT screening test, which indicates they have a drinking problem.
how many women will continue to drink in pregnancy?
4 in 10 in the UK
what is the estimation for every baby born with FAS?
- It is estimated that for every baby born with FAS, there will be 9-10 other babies born with other disorder of the fetal alcohol spectrum.
But also, women have lower levels of alcohol dehydrogenase, what is their role?
This enzyme is responsible for the metabolic breaking down of alcohol. If women have lower levels, they will be able to break down the alcohol more slowly than men, meaning that high alcohol levels will last longer in the bloodstream.
women have 10% more body fat than men meaning what?
Women have 10% more body fat that men, which means that with the same amount of alcohol drink, the concentration of alcohol in blood for women will be higher. But also, women have lower levels of alcohol dehydrogenase
drinking alcohol increases what?
- Macrocytic anaemia will show as increased MCV in the full blood count.
- Increase vulnerability to infection
- Higher risk of accidents
Higher rates of depression, anger, anxiety and misuse of other drugs.
Heavy alcohol intake in the mother is related with impeded absorption of folic acid, which can lead to birth defects.
when may withdraw symptoms be present?
Withdraw symptoms may be present when alcohol tolerance and dependence have been developed: (like palpitations, agitation, tremors or convulsions)
what is alcohols effect o milk production?
For breastfeeding, it is controversial if alcohol consumption is associated with shorter duration of breastfeeding. However, what it is clear is that acute alcohol consumption inhibits oxytocin secretion in the mother and hence affects the ejection reflex of breast milk with a decrease of 10% to 25% of milk production.
The following video shows you some of the long term effects of alcohol in the body
what is the impact of alcohol on blood?
- macrocytic anaemia

the fetal alcohol spectrum disorder (FASD) term cover?
- Fetal alcohol syndrome (FAS)
- Alcohol-related neurodevelopmental disorder (ARND)
- Alcohol-related birth defects (ARBD)
- fetal alcohol effects (FAE)
Partial FAS (PFAS)
as pregnancy goes on how does alcohol impact the baby?
During the 1st trimester the connections between maternal and fetal blood is quite small and the placenta is still developing. Therefore there is a small chance of alcohol passing to baby.
However, later on in pregnancy, the connection between maternal and fetal blood is bigger and the placenta is developed. And the alcohol is more likely to pass to baby.
The impact of the alcohol on the baby and development will depend on what stage she is drinking alcohol

what percentages of women are obese and overweight?
Overall, 15% of the women worldwide are obese. When looking at overweight, up to 40% of women in the world have BMI over 25.
what is obesity?
Obesity is a condition in which there is an excessive body fat accumulation, with multiple pathological consequences for the health of the person. It is usually measured and described by the body mass index (BMI).
is high BMI the only way to measure obesity?
However, it is important to notice that high BMI is not the only measurement of obesity and it needs to be interpreted with caution as it is not a direct measure of adiposity. In highly muscular adults, it may be less accurate.
in women what is a normal waist circumference?
80cm
what are the general risk of obesity to health?
- VTE (especially if BMI>40)
- Cardiac problems
- Hypertension
- Anaesthetic complications
- Low oxygenation
- Risk of gastric aspiration
- Difficult intravenous access
- Wound infection
- Longer hospital stays
- Vit D deficiency
- Mental health issues
- Infertility
maternal impacts of obesity in pregnancy?
- Gestational diabetes (BMI>30)
- Pre-eclampsia (BMI>35)
- Induction
- C-section/instrumental birth
- Labour dystocia
PPH
fetal and neonatal impacts of obesity in pregnancy?
- Miscarriage
- Premature birth
- Stillbirth
- IUGR
- Abnormal FHR patterns in birth
- Less likely to breastfeed
- Macrosomia
- Congenital anomalies (NTD and cardiac)
Admission to NNU
why is anaesthetic complications important to keep in mind with obesity in pregnancy?
- Anaesthetic complications are a very important risk to keep in mind: women with obesity have a decreased lung capacity, with leads to chronic low 02 levels. This chronic lack of oxygen can also compromise fetal oxygenation, making them more likely to experience growth restrictions and abnormal fetal heart rate during labour. Also, the increased stomach capacity and acidity of gastric contents puts them at higher risk of aspiration if they need general anaesthetic during labour. Difficult intravenous access can also difficult management of bleeding or shock in pregnancy.
what are women with a high BMI in pregnancy likely to be offered?
women with a high BMI have a higher risk of gestational diabetes. This is why GTT are offered to all women with a BMI over 30. They also have a higher risk of pre-eclampsia, and as we will see later, this may mean that women with BMI over 35 may be offered prophylactic aspirin during pregnancy.
Women with high BMI are also more likely to be offered induction, either because the increased risk of complications or because they are more likely to go post-dates.
why are women with a higher BMI less likely to breastfeed?
less likely to breastfeed, and the reasons for this can be complex and involve both physical and sociocultural factors. From a physical point of view, they may have a lower milk production, which can be related with undiagnosed thyroid problems or the same insulin-resistance metabolic problems that increase their risk of diabetes. This same insulin-resistance metabolic changes can increase the risk of fetal macrosomia, that then increases the risk of shoulder dystocia and neonatal hypoglycaemia.
what are the neonatal outcomes of babies of women with higher BMI?
neonatal outcomes we know that women of high BMI have a higher risk of miscarriage. This is probably related with the metabolic and hormonal changes related with obesity, that also increase the risk of fertility problems. Probably this is also related with the higher risk of premature birth.
Stillbirths have been explained by the higher risk of abnormal cardiovascular problems in these women, but it may also be related with the chronic low oxygenation levels we discussed in the previous slide. This also increase the risk of IUGR or abnormal FHR patters during birth.
what deficiency are women with higher BMI likely to have?
The folic acid deficiency in women with high BMI increased their risk of neural tube defects. Other congenital abnormalities are also more common, like cardiac ones, but we do not know if this is related with obesity related changes.
women with higher BMI in relation to pre-eclampsia?
- Limitations to appropriate size of cuff
- May need different location
Finally, women with high BMI have a higher risk of pre-eclampsia, but our skill to effectively screen for this condition depends on the use of appropriate equipment. Large blood pressure cuffs should have a width of 40% of the circumference of the arm. And for some women with very large BMI, the large size of standard cuffs may not be enough. Sometimes, instead of placing the cuff in the upper arm, alternative locations, such the forearm may need to be used.
what is the problem with fetal growth with women of a higher BMI?
- Inaccurate SFH measurements (BMI>35)
- Limitations of scan accuracy
When we try to monitor fetal growth: for women with BMI over 35, symphysis-fundal height (SFH) is unreliable to monitor fetal growth, so they will be offered serial growth scans. However, these scans are more likely to be underestimating or overestimating fetal measurements than in women with normal BMI. And considering that scan results are sometimes determinant to decide early induction, it is easy to understand why larger women have a higher risk of induction.
In women with very large BMI, abdominal palpation to assess fetal presentation can be very complicated or sometimes impossible, making these women more likely to require additional ultrasound exposure during pregnancy.
what does the preconceptional care for women with BMI >30 involve?
- Assess other risk factors (especially if fertility treatment)
- Diet advice
- Weight loss advice
5 mg folic acid 3 months before conception (to address their increased risk of neural tube defects)
what does preconceptional consultations for women with higher BMI involve?
Ideally, these women should have preconceptional consultations, most likely with their GP, who will risk assess for other risk factors and comorbidities and should work with them in building a diet and weight loss plan before they plan their pregnancy. Many women with high BMI will require fertility treatment, and sometimes, this risk assessment means that they may not be eligible for treatment until they have improved their health and weight.
what does antenatal care for women with a BMI >30 involve?
- 5mg folic acid up to 12 weeks
- 10mcg vit D supplement
- Review by obstetrician but can remain under midwifery care
- Exercise in pregnancy advice
- Offer dietitian referral
- GDM screening
- VTE risk assessment
Mental health risk assessment
what does antenatal care for women with a BMI >35 involve?
- Consultant-led care
- Serial growth scans
- If other PET risk factors, 150mg aspirin daily from 12 weeks
Consider serial reweighing in 3rd trimester
what does antenatal care for women with a BMI >40 involve?
- Birth in obstetric unit
- At 36 weeks or earlier
- Anaesthetist review
- Tissue viability assessment
- Manual handling assessment
what should all higher BMI take supplement wise?
All women should continue with 5 mg folic acid up to 12 weeks of pregnancy, and use 10 mcg Vit D supplements for the rest of the pregnancy and the lactation period.
in relation to weight what should we do with high BMI women?
All women should be advised about safe exercise in pregnancy and ideally offer dietitian referral. There is a lack of consensus on optimal weight gain during pregnancy, and this is why the focus should be on healthy diet more than prescribed weight gain targets. Actually, it is not uncommon for women with a high BMI to lose weight during pregnancy once.
However, women with BMI of 35 and over, especially those above 40, may be offered serial weight in the third trimester. The purpose of this is not really to improve outcomes in the mother, but to be able to have more accurate manual moving and handling assessments, that could impact the discussion around their birth options, p.e. about the use of a birthing pool.
what are the intrapartum guidelines for women with BMI >30?
- Ranitidine 8 hourly
- Active third stage
- CTG only if fetal concerns
- Encourage mobility
- Prevent pressure sores
If c-section prophylactic antibiotics at time of surgery
what are the postnatal guidelines for women with BMI >30?
- Breastfeeding support
- Continue on 10mcg vit D supplement while feeding
- Plan to restart exercise
- Mental health risk assessment
VTE risk assessment and prophylaxis if other risk factors
what are the intrapartum guidelines for women with BMI >40?
- IV access early in labour, considering sitting a second cannula
- Inform anaesthetist on admission
Birth pool usually contraindicated
what are the postnatal guidelines for women with BMI >40?
Prescribe VTE prophylaxis for 10 days
what medication should women with high BMI get in labour?
During labour, women with high BMI should be offered antiacid medication, like ranitidine every 8 hours, to reduce the risk of aspiration if GA needed.
what are the recommendation about PPH prevention for women with high BMI?
Due to the higher risk of PPH, all women should be offered active third stage. However, for women with BMI above 40, the RCOG recommends having IV access sited early in labour, considering even if second cannula may be desirable, as IV access in these women tends to be very difficult enough.
is CTG routine in labours of women with high BMI’s?
CTG should only be used if there are fetal concerns. Considering that IA may be difficult to achieve in women of very high BMI, they are more likely to be offered internal fetal monitoring during labour, but there is not really evidence to support this practice, which have other risks associated.
why is mobility important during the intrapartum period for women with high BMI’s?
Mobility is essential for these women, especially considering the increased risk of pressure sores if lying on bed for prolonged period of times. However, as we discussed before, due to concerns of moving and handling, birthing pool is usually contraindicated for women with very high BMI.
