Objective:The aim
of this study was to evaluate the
effects of 6 months of balanced
caloric moderately deficit diet
program combined with individualized
moderate Physical exercise on the
body weight, body composition and
fat distribution of adolescent
girls.
Subjects & methods
:It was a longitudinal survey
comprised 1244 adolescent girls,
aged from 14 to 18 years. Their body
weight and height were measured, and
the BMI was calculated.
Results Of the
total sample, only one hundred and
eleven girls (8.9%), with mean age
was 15.82+ 0.75 years, were
suffering from obesity based on
their body mass index; which is
greater than the 95th percentile for
age and gender based Egyptian Growth
Reference Charts. These obese girls
were undergoing nutritional
intervention (specific dietary
program, nutritional education and
exercise) for 6 months. At the start
of this program, the obese girls
were assessed for their
anthropometric measures: the body
weight, body height (or stature),
body mass index (BMI), waist and hip
circumferences, waist/hip ratio,
skin folds thickness at 5 sites and,
according to BIA, their body
composition. This assessment was
repeated after 6 months. Only thirty
eight girls completely finished the
program till the end. Results: The
current study showed that after
following the dietary program and
physical activity, there were highly
significant reduction in waist
circumference, the skin fold
thickness at the 5 sites (triceps,
biceps, sub scapular, suprailiac and
abdominal), peripheral and central
adiposity, and fat mass, and
significant reduction in body
weight, hip circumference and
fat%.The change in BMI was not
significant. On the other hand,
there was a highly significant
increase of the total body water and
Basal metabolic rate after following
the dietary program and physical
activity.
Conclusion: The
nutritional intervention program was
succeeded in 38 obese adolescent
girls. These girls show highly
significant reduction in body
composition and body fat
distribution.This revealed that the
combined program of diet restriction
and exercise is necessary
