NUTR2005: Lifespan Nutrition Assessment 1 Part A Workbook Activities

This document presents a student's complete response to the NUTR2005 Lifespan Nutrition Assessment 1 Part A workbook, which focuses on nutritional needs across the lifespan. The assignment includes four key activities. Activity 1 involves a nutritional assessment of a 35-year-old male, calculating his estimated energy requirements using the Schofield equation, comparing his anthropometric measurements and dietary intake to Australian guidelines, and providing an evidence-based assessment of his health status. Activity 2 explores nutrition in male and female preconception, focusing on the importance of iron supplementation for female fertility. Activity 3 examines nutrition in pregnancy, addressing the trimester of pregnancy, energy requirements, dietary recommendations, and supplement suggestions. Finally, Activity 4 analyzes a childhood nutrition case scenario, assessing a 1-year-old's growth using a WHO chart and providing dietary recommendations for her parents. The student provides detailed calculations, comparisons, and evidence-based recommendations throughout the workbook.

Assessment 1 Part A Workbook
Activities.
NUTR2005 Lifespan Nutrition
Activity 1: Nutritional Assessment Case study (approx. 200 words)
Mark is a 35-year-old male in a sedentary job. He weighs 105kg and is 1.73m tall with a waist
measurement of 101cm. He walks to and from work every day (20 minutes) and plays golf on the
weekend. Mark’s 24-hour recall diet is as follows:
Breakfast: 3 x Wheat Bix with a cup of full cream milk
Morning Tea: Large flat white with 1 sugar
Lunch: Ham (2 slices) and cheese (2 slices, full fat) sandwich (white bread) with lettuce (1piece)
Afternoon tea: Large flat white with 1 sugar. Large blueberry muffin.
Dinner: Spaghetti Bolognaise (1 cup mince, 1 cup pasta, passata and herbs). 2 x Beers.
Supper: 2 scoops of vanilla ice cream
Case study Questions:
a) Calculate Mark’s Estimated Energy Requirement using the Schofield equation. In your
answer, indicate how you calculated this.
The estimated energy requirement for Mark is 2078 kcal/day and 167 kcal could be +/-
according to his sedentary lifestyle. This result was calculated with the help of Schofield
equation and the equation for the age group of Mark is BMR = 11.472 x (wt kg) + 873.1 SEE
= 167.
b) Compare Mark’s anthropometrical measurements to the Australian Guidelines.
The anthropometrical measurement of Mark shows that his weight is 105 kg, his height is
1.73 meter, and his waist measurement is 101 cm. According to the Australian guidelines the
recommendation for males is less than 94 cm, which shows that they are not at risk. More
than 94 cm shows increased risk (Goh et al., 2014).
c) Compare Mark’s dietary intake of food groups against Australian recommendations.
According to Australian recommendations the ideal serving for men between the ages of 19-
50 is 6 for vegetables and legumes, 2 for fruits, 6 for cereals, 3 for lean meat, 2.5 for milk
products, and 0-3 for additional food groups. The dietary intake of Mark consists of refined
sugar and cereals, and it deprived of fruits and vegetables, which is not recommended for his
condition as he is overweight (Fayet-Moore, Baghurst & Meyer, 2015).

d) Based on your previous answers, make a short evidence-based assessment on Mark’s
current health status.
Mark’s current health status is not favourable as his anthropometric measurement shows that
he is at risk. His diet consist of unhealthy and sugary foods, which is not required for his
condition at the moment. He is overweight and that can lead to several chronic lifestyle
diseases (Robertson et al., 2015).
Activity 2: Nutrition in Male and Female Preconception (200 words)
Choose one of the following topics and briefly discuss its importance/ use in relation to male and
female fertility / preconception, referring to the evidence.
1. Folic acid in Female preconception OR
2. Iron in Female preconception OR
Iron is an essential nutrient that is needed for healthy pregnancy and a normal delivery. Low
levels of iron are linked to several deficiency diseases such as anaemia that also elevates the
chances of parasitic infections such as malaria, schistosomiasis and hookworm. These
diseases increase the complications during pregnancy and that is the reason for consuming an
optimum amount of iron during pregnancy. An estimation by WHO shows that 38.2% of
pregnant woman all around the world suffer from anaemia during pregnancy. During the
stages of preconception, iron supplements should be included in the diet to reduce the chances
of anaemia. Negligible amount of iron content leads to poor maternal and infant outcome,
which makes it necessary to keep an optimum iron store during menstruation so that there are
no complications in the reproductive age. It leads to a low birth weight and premature
delivery including low milk production after delivery and causing tiredness. The major reason
for post natal depression is micronutrient deficiency and it majorly includes iron because it
causes anaemia in woman and also the foetus if iron supplements are not taken during the
preconception stage. Tissue oxygenation happens due to metabolic processes, which happens
with the help of iron as it is the reason for haemoglobin production (Nguyen et al., 2016).
3. Zinc in Male preconception OR
4. CoQ10 in Male preconception
Activity 3: Nutrition in Pregnancy (approx. 200 words)
Watch the case study excerpt video, available in the Assessment Information area.
Case study Questions:
a) Which trimester of pregnancy is Pam currently in?
Page 2 of 6

Pam is in her 2nd trimester because she is in the 15th week.
b) Should Pam be eating for two? How much extra energy (in Kilojoules) does Pam need from
her diet in her current trimester of pregnancy?
It is not necessary to eat for two during pregnancy because it can cause weight gain after
delivery and it can become difficult to lose weight after that. During second trimester 1400 kJ
is recommended as an energy intake. This will be the extra energy utilized from the diet in the
second trimester by Pam (Malek et al., 2016).
c) To give Pam examples of what your increase in energy might look like, create three
examples of well-balanced meals / snacks that will help Pam achieve her increase in energy
recommendation per day (Use Foodworks (xyris.com.au), Foodzone (foodzone.com.au) or
Nutritics (en-au.nutritics.com) to create accurate recommendations)
1. Eggs Benedict
2. Mashed potatoes with butter
3. Walnut and banana smoothie
d) What are the current recommendations regarding fish intake in pregnancy?
Fish with high levels of mercury are not recommended for pregnancy such as sharks,
swordfish, ling and orange roughy. Fish with low levels of mercury are suitable for them such
as salmon, prawns, lobsters and canned tuna. The recommended allowance is one serving
(150g) every fortnight (Starling et al., 2015).
e) Make a recommendation of one supplement for Pam. Please justify your answer pointing to
research.
Pam already takes folic acid supplements and vitamin B-12 works the best with this because
it helps in preventing complications and birth defects in the foetus. The focused area
includes the baby’s brain and spinal cord, which affects the neurological development of the
child. One of the sources of vitamin B12 is fortified cereals.
Activity 4: Nutrition in Childhood case scenario (approx. 200 words)
Emily is a 1-year-old toddler. Her weight has been recorded as:
Age Weight
Birth 3.2 kg
1 month 4.1 kg
3 months 5.9 kg
6 months 7.2 kg
9 months 9.8 kg
12 months 11.5 kg

a) Plot Emily’s growth using the WHO weight-for-age growth chart and attach it to this
workbook. The chart can be found in the assessment information area.
The chart is given in the end of the assignment.
b) At what age did Emily’s weight start changing percentiles?
During her birth the weight percentile was 0 and it started changing in the 1st month as it was
54.
c) Make an assessment on Emily’s weight over time and discuss possible reasons for these
changes.
Emily’s weight started changing over time as the months started increasing. Initially her
growth percentile was 0 but in the 1st month it increased to 54. This showed that her growth
and development was taking place as usual just like other kids of her age. The possible reason
for the changes is her dietary intake that has been helping her growth in every month (Marks
et al., 2015)
d) What recommendations would you make for Emily’s parents?
The recommendations should be given to her parents that the dietary allowance should be
followed suitable for a 1 year old toddler. The recommended allowance suggests that starchy
food should be given 5 times a day, fruits and vegetables 5 times a day, dairy food 3 times a
day, protein rich food 2 times a day (Lumeng et al., 2018).
