Abstract
Obesity is one of the most serious problems in the global public health domain.
Obesity increases the risk of high blood pressure, dyslipidemia, type 2 diabetes, and
cardiovascular diseases (WHO, 2018). Obesity is preventable disease and the prevention
of obesity is easier, less expensive, and more effective than treating obesity if it has
developed (Aktar et al., 2017). A person’s unhealthy eating habits and lack of physical
activity are major contributors to becoming overweight or obese, which are linked to a
lower quality of life and an increased risk of developing life-threatening diseases
(Parkman, 2020). The rapid increase in technology has changed the way many people
perform day-to-day jobs from paying bills to purchasing books. It is no surprise that
with these increases in technology a change in attitudes towards these new tools is more
evident. Many people now prefer to use technology to facilitate their daily routine and
to change the way people deal with weight management (Pal et al., 2018). Telephonic
weight loss applications can provide an easy, safe and cheap way to overcome obesity
by ensuring a high level of usability and encouraging individuals to change their
lifestyle and become more active. Weight management applications encourage people
with obesity to be active and change their lifestyle in order to overcome obesity
(Nielsen, 2019).The aim of the study was to examine the effect of telephonic weight loss
coaching program on body composition among health field university students.Research hypotheses1. Obese students who will receive telephonic weight loss coaching program will
probably reduce fat percentage than those students who will not receive.2. Obese students who will receive telephonic weight loss coaching program will
probably reduce body mass index than those students who will not receive.Research designQuasi-experimental design (study and control group) with pre and posttest was
utilized.Study settingThe study was conducted at three health field faculties including Faculty of
Nursing, Faculty of Veterinary Medicine and Faculty of Applied Health Science
Technology in Menoufia University, Menoufia Governorate, Egypt.Study sampleA multi-stage random sampling technique was used to select the setting through:
First stage: A purposive selection of 6 faculties out of 18 faculties at Menoufia
Governorate, Menoufia University, including Faculty of Nursing, Faculty of Veterinary
Medicine, Faculty of Applied medical Science, faculty of medicine, faculty of pharmacy
and technical institute of nursing.Second stage : Three faculties were selected by simple random sample including
Faculty of Nursing, Faculty of Veterinary Medicine, Faculty of Applied medical
Science.Third stage: One academic year was selected from each faculty by simple random
sample (fourth year).Fourth stage: Systematic random sample of 200 university students of both sexes were
selected which was divided into two equal groups (study group and control group
including 100 subjects for each one).Instruments of the study:Data was collected through the following instruments:Instrument I: Structured interview questionnaire:It was developed by the researcher after reviewing the related studies. It
included demographic data, Student health habits questionnaire and Food frequency
questionnaire.Instrument II: Bio-physiological Measurement which include two parts:Weight, height, water percentage and fat percentage measurement.Instrument III: The compliance assessment likert scale:It included two parts diet compliance and exercise compliance.The main finding of the study revealed the following:There was highly statistical significance difference regarding dietary health habits
between study and control group as number of meals taken out door was decreased,
method of cooking changed to healthier method and vegetable oil was used in
cooking rather than mixed fat (p<0.0001).
There was highly statistical significance difference distribution of food items
between study and control group there was a significant higher consumption of
fruits, vegetables, fish, egg, cheese, yogurt, milk and fruit juice and lower
consumption of packaged ready foods, snacks, coffee and tea, soft fizzy drinks,pizza, bread /cereals, chips, meat products (sausages – burger), pasta /rice, cakes
and ice cream, chocolate and biscuits among study group compared with control
group(p<0.0001).There was highly statistical significance difference regarding physical exercise
between study and control group, majority of study group practiced exercise after
starting TWLC program (p<0.0001).
There was highly statistical significance difference regarding BMI, BMI reduced
among study group after intervention compared to control group (p<0.0001).
There was highly statistical significance difference regarding body fat percentage,
body fat percentage reduced among study group after intervention compared to
control group (p<0.0001)Conclusion:Based on the findings of this study, it was concluded that:After implementation of telephonic weight loss coaching program on health
field university students, there was statistically significant reduction in fat percentage
and body mass index as they decreased after the program in study group compared to
control group. Also there was statistically significant improvement in dietary and
exercise health habits in study group compared to control group.Recommendations:Based on the findings of the present study, the following recommendations were
suggested:1- The application of mobile health nursing intervention for one year to better
determine the effectiveness of mobile health application on weight loss
management.Nutritional educational programs among pre college students should be encouraged
to promote healthier eating habits and lifestyles from young age to adulthood.
3- To offer weight loss app in Arabic version to be available to person with low or
moderate educational level who cannot completely understand English language.
