on the following:
1. Dietary intake and snack consumption
2. Anthropometric measurements and
biochemical markers
3. Exercise patterns
2
Participant Recruitment
• Campus wide e-mail
• Table tents around the cafeteria, computer labs
and library

4
Total Study Subjects
Subjects were required to complete the following:
Survey 1:
- Completion of 22 question survey pertaining
to student status, demographics, health status
and exercise habits
Survey 2:
- Completion of 19 question food intake
questionnaire focusing on food preferences, meal
patterns, cultural habits and changes in food habits
Health Assessment:
- Collection of anthropometric measurements, lipid
values, blood pressure and InBody assessment
5
Data Collection Tools:
6
Data Collection Adherence for Accuracy
• Students were assigned measurement stations
• Height and waist circumference were read on two
separate occasions for accuracy
• Blood Pressure was taken after student was resting in
a chair for >5minutes where 10 separate readings were
taken(5 per arm).
7
Data Collection Instrument:
Block Fat Screener
• A means of providing a brief and inexpensive method of determining
fat intake.
• The block fat screener contains 17 food items that are typically
high in fat.
• Each food item was given a score 1-5 based on how often the
participant consumed these food items.
• The fat score was calculated as the sum of the numerical values
of all 17 food items.
• The fat score was utilized in mathematical equations to calculate
total fat(grams), percent total fat, saturated fat (grams), and
cholesterol intake (milligrams).
• 150 participants completed the Block Fat Screener.
8
Data Collection Instrument:
Fruit-Vegetable-Fiber Screener
• Inexpensive method of determining fruit, vegetable
and fiber intake.
• Screener includes 10 items:
o the first seven determine fruit servings using USDA
Food Pyramid definitions of servings.
o The last 3 items determine average grams of fiber
consumed on a given day.
• Predictive equations provide estimates for fruit and
vegetable servings, vitamin C(mg), Magnesium(mg),
potassium(mg) and dietary fiber(g)
• Data collection was done online as part of a second
survey.
9
Data Collection Instrument: Godin
Leisure-Time Questionnaire (GLTQ)
• An inexpensive method to measure the frequency and
intensity of exercise, and frequency of leisure time
physical activity (LTPA) of a 7 day period. This
questionnaire is comprised of two questions.
• GLTQ was Included in online survey 1
• Results (Self reported)
– Frequency
of weekly LTPA (often, sometimes, or rarely/never).
– Reported frequency of each intensity of exercise was used to
calculate total
•
METs (metabolic equivalents) for each; strenuous,
moderate, and mild METs.
• Total Godin Score
– Calculated for each subject.
– Used to represent the sum of total weekly METs.

What the Literature Says:
• Many studies have shown a dietary pattern of snack consumption
among the college population (1,2,3).
• A recent study in 2009, had findings that university students from
Scotland (a more western country) consumed more chocolate, bars and
crisps (p<0.05) when compared to university students from Greece (a
country considered to be transitioning from a traditional diet) (3).
• A study in 2010, found that U.S. born Mexicans reported eating
significantly more non-Mexican fast food, snacks, desserts candy and
sugars compared to Foreign born Mexicans (p<0.001) (4).
• Another study in 2010, found high-acculturated Korean Americans ate
more western foods and significantly more raw vegetable salad (p<.027)
compared to low-acculturated Korean American college students (5).

Cakes, 5) Ice Cream, 6) Potato Chips or Other Chips, 7) Personally
Prepared foods (Traditional), 8) Juice, 9) Snack Bars, 10) Breads or
Cereals, 11) Nuts 12) Candy, 13) Pizza/Hamburger and 14)
Sandwich.
Frequencies of Variables
The top three snack food preferences that had the greatest frequency of

Snack Foods among Ethnicities
Significant Findings:
•
Among those responding “yes” to the consumption of Fruits and Vegetables
as snacks, ethnic groups with the highest intake were White (83.3% of
respondents, n=60) and White (Middle Eastern) (85.7% of respondents,
n=12).
•
Among those responding “yes” to the consumption of Traditional Foods
(personally prepared) as snacks, ethnic groups with the highest intake were
Asian Indian and Chinese (36.8% of respondents, n=14).
•
Among those responding “yes” to the consumption of Candy as snacks, ethnic
groups with the highest intake were Asian Indian and Chinese (42.1% of
respondents, n=16).
•
Among those responding “yes” to the consumption of Pizza/Hamburger as
snacks, ethnic groups with the lowest intake were White (6.9% of
respondents, n=5) and Hispanic or Latino(7.7% of respondents, n=1).
•
Among those responding “yes” to the consumption of Sandwich as snacks,
ethnic group with the lowest intake is White (19.4% of respondents, n=14).

Snack Foods among Generations
Significant findings:
•
Among those responding “yes” to the consumption of Fruits and
Vegetables as snacks, generations with the highest intake were 5th
generation (87% of respondents, n=40) and 4th (84.6% of respondents,
n=11). Among those responding “yes,” the intake increased with
each generation from 1st to 5th generation.
•
Among those responding “yes” to the consumption of Traditional
Foods (personally prepared) as snacks, generations with the highest
intake were 1st (22.6% of respondents, n=7), 2nd (35.9% of
respondents, n=14), and 3rd (22.2% of respondents, n=2). Among
those responding “yes,” the intake declined in the 4th and 5th
generation.
•
Among those responding “yes” to the consumption of Sandwich as
snacks, generations with the highest intake were 2nd (46.2% of
respondents, n=18), 1st (38.7% of respondents, n=12), and 3rd (33.3%
of respondents, n = 3). Among those that responded “yes,” the
generations after the 3rd decline in their intake of Sandwiches as a
snack.
Ho3: There is no relationship between how
snacks are obtained and student’s ethnicity
Rejected. A significant interaction was found
(χ2(4)= 13.71, p=0.008, eta = 0.251).
Significant Findings:
Among those that responded as “varies” to obtaining snacks,
the ethnicity with the highest response, is White (Middle
Eastern) (78.6% of respondents, n=11). The White (Middle
Eastern) is also the ethnicity that had 0 responses to “prepared
at home” to obtaining snacks (0% of respondents, n=0) and the
ethnicity with the lowest response to “prepared at home” is
Asian Indian and Chinese (2.6% of respondents, n=1)
Ho4: There is no relationship between how
snacks are obtained and student status.
Accepted.
No significant relationship was found (χ2(2)= 1.52,
p=0.462, eta = 0.11). How snacks are obtained and
student status appears to be independent.
Snack Consumption Conclusions
• From all 14 snack foods that were compared to
ethnicities, 5 snack foods (fruits or veg., traditional
foods, candy, pizza/hamburger and sandwiches) were
found to have a significant relationship to ethnicities.
• Fruits or vegetables snack foods have a significant
relationship to generations. The intake increased with
each generation from 1st to 5th generation.
• Traditional (personally prepared) snack foods and
sandwiches as snacks have a significant relationship to
generations. The intake of both the snack foods
declined in the 4th and 5th generations.
Snack Consumption Conclusions
• How snacks are obtained (prepared at home,
purchased, or varies) and a student’s ethnicity has
a significant relationship N=137.
• How snacks are obtained has no significant
relationship to student status (part time or full time)
N=127.

Benefits of Physical Activity
• Physical activity (PA) can help prevent a variety of
chronic illnesses, that have become prevalent in
westernized society.
• PA has been shown to have many positive effects on
a variety of metabolic health factors.
o
Decreasing triglyceride total cholesterol, and LDL levels.
 Protective against CVD and metabolic syndrome.
o
Increasing HDL levels.
 Protective against CVD and metabolic syndrome.
o
Decreasing BMI and PBF.
 Protective against obesity, diabetes, HTN, CVD, metabolic
syndrome.
 Aids in weight loss/weight management.

La Forge R, 2002
Physical Activity Guidelines for Adults
At least 150 minutes of moderate intensity physical
activity or 75 minutes of strenuous intensity aerobic
physical activity per week for significant health benefits.
Strenuous Exercise
• Jogging/running
• Swimming laps
• Singles tennis
Department of Health and Human Services, 2009
Moderate Exercise
• Walking fast
• Water aerobics
• Doubles tennis.
33
Previous Research
• Physical Activity and College Students:
o
As freshman, 29% of students did not exercise regularly;
by senior year the amount of physically inactive did not
change.
o
More than 50% of undergraduates were sedentary or
exercised on an irregular basis.
o
29% of college students living on campus and 28% living
off campus reported being sedentary or lightly active.

Previous Research
Physical Activity and Acculturation:
• Foreign born Mexicans participated in fewer weekly bouts of
low intensity physical activity compared to U.S. born
Mexicans.
o
Inactivity and low intensity physical activity increased with
generation of residence in the United States among Mexicans and
Cubans.
• Studies on Arabic women in America suggest that physical
inactivity is more common than American women.

Trends
• Low risk TC and PBF categories had higher mean strenuous METs
and Total Godin Score.
• Low risk HDL cholesterol category had higher mean strenuous
METs.
• Low risk LDL and TG categories had higher mean strenuous,
moderate, and mild METs.
• Overweight BMI category had higher mean mild and moderate METs
and Total Godin Score.
• The more LTPA reported the higher mean BMI and TGs.
• The more LTPA reported the lower mean HDL.
55
Conclusions
• BMI is higher with more LTPA, Moderate METs, Mild METs and
higher Total Godin Score.
o Muscle mass increases weight; may be contributing to
higher BMI in individuals.
o May not be the best tool to use alone to determine disease
risks.
• Higher Total Godin Score in low risk TC, LDL and HDL
cholesterol, TG, and PBF categories.
o Supports research on the benefits of exercise on these
metabolic risk factors.
• Significant difference between LTPA frequency and ethnicity.
o Displays a need to emphasize the importance of exercise to
college students of various ethnic backgrounds.

Anthropometrics
Elizabeth Chlopek
57
What the Literature Says:
• Of the methods used to measure body fat and its distributions,
anthropometric measurements play an important role in clinical practice.
• The risk for overweight and obesity has shown to be independently
associated with excess abdominal fat. (1)
• Body mass index (BMI) is most widely used to measure total adiposity and
to categorize obesity, while waist circumference (WC) is an alternate
marker for abdominal adiposity. (1)
o
Some research shows BMI as a indicator for man of overweight/obese
status. With women, waist to hip ratio and waist circumference was a better
indicator of overweight/obesity status. (2)
• Some research has shown WC as a better indicator of abdominal obesity
(1)
• More research is needed to determine what anthropometric measures
perform the best in assessing obesity related health risks and what cut-off
points should be used in clinical settings.
o
Also, related ethnic differences need to be better understood. (1)

than is recommended.
• Over half of female college students tend to
underestimate fat content in foods and dietary fat
intake.
• Minority ethnic groups tend to have a higher dietary fat
intake.
• Improper fat intake (diets high in saturated fat) places
individuals at increased risk for cardiovascular disease
as lipid serum levels are increased.

Conclusions
• There are significant differences in total fat and saturated fat
intake between males and females. Males are shown to
consume on average more saturated fat than women and less
total fat than woman.
• There is a significant difference between saturated fat intake
and total HDL levels.
• There are no significant differences across ethnicity, BMI
categories, and percent body fat categories when compared
total fat intake and saturated fat intake.
• There are no significant differences with total cholesterol,
triglycerides, LDLs when compared to total fat intake and
saturated fat intake.
• All 150 participants who completed the block fat screener were
shown to have a fat intake above the recommended daily
allowance of <30% fat.
Fruit Vegetable & Fiber
Melinda Hamilton-Smith
What the Literature Says:
• Different forms of antioxidants present in fruits and
vegetables as well as the fiber content and the rich
amount of vitamins, minerals, and trace elements
provide health benefits.
• The benefits of antioxidants have been shown to
include; reducing LDL oxidation, altering cholesterol
metabolism, and lowering of blood pressure
• Fruit, vegetable, fiber and fat intake are most closely
associated with morbidity and mortality
What the Literature Says:
•
Outpatient controlled study: increased their overall fruit vegetable and fiber
consumption over a 10 day period. Total cholesterol decreased by 16%,
LDL decreased by 22%, VLDL decreased by 35%, fasting insulin
decreased 68%. fasting glucose decreased 5% but was not statistically
significant.
•
Cross-sectional study of 422 males self reported intake found associations
between intake of fiber-rich foods, and alcohol to be large determinants of
cardiovascular disease risk factors including increases in serum lipid
levels, waist circumference, and blood pressure.
•
Eighty-eight healthy subjects randomly assigned to a control group with
high fiber plant foods, fruits, berries, vegetables, whole grains, rapeseed
oil, nuts, fish and low-fat milk products, while avoiding salt and added
sugars or saturated fats. Significant lowering of plasma levels of
cholesterol, LDL-C, HDL-C, apoA1, ApoB, ApoB/ApoA1 ratio, and
LDL/HDL ratio.

Conclusion:
• Fruit, vegetable, and fiber intake was not found to be significantly
affected by ethnic background.
• A statistically significant difference was found in fiber intake. Males
were found to consume more fiber on a daily bases averaging
23.34g of fiber/day where females average intake was only
19.22g/day. Further, 52.9% of males were found to meet the dietary
recommendations for fiber and only 47.1% of females met these
same recommendations.
• The amount of fiber, fruits and vegetables consumed by the
students did not show any significant difference in their blood lipid
levels (TC, LDL, HDL, and TG) or BMI category.
