Flashcards in WK 2- Child Nutrition Deck (20):

What is growth stunting

-stunting is low height for age
-moderate to severe stunting is below minus 2 standard deviations from median height for age of reference population
-rate of stunting in a country is a representation of that countries nutritional levels
-children who have a low nutritional intake in childhood are often shorter as adults


What are some of the effects of stunting

-traps people into a lifelong cycle of poor nutrition, illness, poverty and inequity.
-The damage to physical and cognitive development, especially during the first two years of a child’s life, is largely irreversible.
-A child’s poorer school performance results in future income reductions of up to 22 per cent on average.
-As adults, they are also at increased risk of obesity, diabetes and cardiovascular disease.


What is wasting

low height for weight
-a strong predictor of mortality among children under five. It is usually the result of acute significant food shortage and/or disease


What is iodine deficiency

-lack of iodine in diet--> largest cause of preventable mental retardation
-causes cretinism, stillbirth and miscarriage, while even mild deficiency can significantly affect the learning ability of populations.


How can iodine deficiency be prevented

by ensuring that salt consumed by households is adequately iodized


What countries are most affected by iodine deficiency

South asia and sub-Saharan Africa have large amount of households who are not consuming adequately iodized salt


What are physical signs of iodine deficiency

goitre (swelling of thyroid gland) and cretinism (stunted physical and mental growth)


What does vitamin A deficiency cause

blindness (xeropthalmia) and renders children susceptible to common childhood killers: measles, diarrhoea, malaria and pneumonia
-also helps prevent maternal mortality and may reduce mother-to-child transmission of HIV.


Who is at risk of vitamin D deficiency

•Babies of mothers with darker skin types, l
•living in high latitude
•Babies and mothers who wear concealing clothing,
•Babies and mothers who spend a lot of time indoors
-Populations who are forced to remain inside due to shelling or fighting are also at risk
-Populations living in desert areas where atmospheric dust acts as a filter for ultra-violet light are susceptible to vitamin D deficiency, particularly when people stay inside to avoid the heat of the day and wear extensive clothing.
•Babies of obese mothers (BMI >30).


What are the clinical signs of vitamin D deficiency

Rickets-> have reduced bone growth, are anaemic and prone to resp infection
-have delayed closire of the fontanelles
-squared head caused by swelling of frontal bone structure
-swollen wrists and ankles


Where is rickets most common

most Middle Eastern countries in a geographic band going from Morocco to Pakistan and can occur as far south as Ethiopia and is also common in parts of eastern Europe.


What happens to children who are undernourished in the first 2 years (1000 days)

-poor fetal growth and stunting that leads to irreversible damage-> such as shorter adult height, lower attained schooling, lower income and decreased offspring birthweight
-children will put on weight rapidly in childhood-> leads to high risk of chronic disease (like diabetes and stroke)


What are some causes of poor growth in children (organic)

-Inadequate intake –eg swallowing problem, cerebral palsy
-Malabsorption –eg cystic fibrosis, coeliac disease
-Excessive losses –eg diarrhoea, vomiting, protein loss in urine etc.
-Increased caloric requirement –chronic infection, Heart disease, etc
-Endocrine –eg Hypothyroidism
-Genetic –eg Turners Syndrome
-Fetal effects –IUGR, FASD


What are some causes of poor growth in children (non-organic)

food not available, money a problem, attachment problem, maternal depression, family violence, drug and alcohol use by carers or in household. child neglect. mental health problems in household.
-organic factors can be linked to non-organic factors (ie. Poor sanitation= diarrhoea, UTI)


How can malnutrition in children be prevented

Maternal nutrition and prevention of low birth weight
-Infant and young child feeding→ Breast feeding (1 hour of birth) and continued exclusive breast feeding for 6 months followed by continued feeding to 2 years.
-Complimentary feeding from 6 months
-Prevent micronutrient deficiency
-Prevent and treat acute severe acute malnutrition
-Sanitation and clean drinking water
-Healthy practices and use of health services.


What are the main causes of death in children globally

malnutrition, pneumonia, infection, prematurity, injuries, malaria


What is underweight measuring

weight for age


How many SD away from the mean score is 'moderate'

-2 to -3


How many SD away from the mean score is 'severe'



What is the management for acute severe malnutrition

-correct dehydration by using oral dehydration formula→ low osmolarity
-treat infection→ antibiotics and deworming
-malnutrition→ immediately give Vit A
-begin feeding slowly→ don’t want re-feeding syndrome (causes electrolyte imbalances when person who has little calorie intake suddenly gets large amount of calories)
-stimulation child to promote emotional and sensory development
-measles vaccine→ malnutritioned children are susceptible
