NUTR 35. 210 LAB 7

OBJECTIVE: To gain experience collecting and analyzing anthropometric data for different life stages that are important in the assessment of overall nutritional status.

In some populations it is difficult to assess body composition, in particular BMI. For example in children their height and weight is very dependent on their age and gender, and a simple BMI will not be accurate. Other examples include assessing height and weight in people who are in wheelchairs or have osteoporosis.

For today’s lab you will assess growth for a newborn, an older baby, a toddler, and a wheelchair-bound elderly person. You will use dolls to measure head circumference, length, and weight and plot growth on the growth charts. Please note if your model is a boy or girl and how old they are, you will need this to complete the growth chart. For the elderly adult you will simply use yourself to assess height using arm length.

INFANTS AND CHILDREN:

For head circumference:

·  Wrap the tape snugly around the widest possible circumference - from the most prominent part of the forehead (often 1-2 fingers above the eyebrow) around to the widest part of the back of the head.

·  Try to find the widest way around the head.

·  Re measure 3 times, and take the largest number and record in raw data table.

For length:

·  Position against a flat surface.

·  Use the tape measure to calculate the distance from the top of the head to the heels. Measure length to 0.1 cm or 1/8 inch and record in raw data table.

For weight:

·  Weigh to the nearest 0.5 ounce and record in raw data table


FOR ADULTS:

Clinically, the most useful measurement for those who are bedridden, or with severe spine curvature is the demi-span. Demi-span is measured as the distance from the middle of the sternal notch to the tip of the middle finger in the coronal plane. Height is then calculated from a standard formula. You may use yourself as a model.

Lab report (Please type the final report)

Introduction:

Your introduction should include a short title for this lab.

You also need a discussion of why this lab is important, what you hope to learn from it, and what the information gathered can be used for.

Materials and Procedures:

This section should include a list of any materials or supplies you used to complete this lab.

You also need to include a Step by Step description of what you did during this lab.

Results and Analysis:

You will need to turn in your raw data tables and growth charts.

You will need to make a table that summarizes the growth information for the newborn, baby, small child, and adult.

Conclusions:

You will need to summarize the main findings and analyze what the results are telling you. Make sure to discuss if the data on the growth charts appear normal and how closely demi span estimates your height.

Conclusions Part 2

How do you diagnose “failure to thrive”?

At what age can you first diagnose someone with obesity?

How do you define obesity in children?

The WHO growth charts for boys and girls 0-24 months are here:

http://www.cdc.gov/growthcharts/who_charts.htm

You will need to find plot and find that percentile for

Head circumference AND Length for age (on the same chart)

Weight for age AND Length for weight(on the same chart)

NOTE be sure you’re using the right chart for the sex of your baby.


Instructor Signature______

Excellent (3 pts) / Good (2 pts) / Adequate (1 pts) / Needs Work (0.5 pt) / Not attempted (0)
Introduction / Includes the question or purpose to be answered by the lab, states the reason why this is important
and has a short, relevant title. / One of the "excellent" conditions is not met, two conditions met / Two of the "excellent" conditions is not met, one is met / Introduction present, no exemplary conditions met
Materials and Procedures / Description or step-by-step process is included, could be repeated by another scientist / Description included, some steps are vague or unclear / The description gives generalities, enough for reader to understand how the lab was conducted / Would be difficult to repeat, reader must guess at how the data was gathered or lab was conducted
Results and Analysis / Results and data are clearly recorded, organized so it is easy for the reader to see trends. All appropriate labels are included / Results are clear and labeled, trends are not obvious or there are minor errors in organization / Results are unclear, missing labels, trends are not obvious, disorganized, there is enough data to show the experiment was conducted / Results are disorganized or poorly recorded, do not make sense; not enough data was taken
Conclusions / 1. Summarizes data used to draw conclusions
2. Conclusions follow data (not wild guesses or leaps of logic),
3. Discusses applications or real world connections / 2 of 3 of the "excellent" conditions is met / 1 of 3 of the "excellent" conditions is met / Conclusion section is present but no conditions are met
Conclusions part 2 / Answers all additional questions required correctly. / Answers 2 or 3 additional questions correctly. / Answers 1 of 3 additional questions correctly. / Attempts to answer questions but none are correct.
