Abstract
Body Mass Index and Growth Spurt in School Teenagers (13-18 years) of Atse Zerea Yaekob
Primary Full Cycle School and Basso General and Preparatory School in Debre Berhan, Central
Ethiopia by Meklit Trsitewold,Addis Ababa University in 2018.
Body mass index is a value derived from the mass and height of an individual and calculated by
the body mass divided by the square of body height and its value categorized based on CDC
standard under normal weight, overweight, underweight and obesity. Growth spurts are when a
lot of growing takes place in a short period of time. A rapid rise in height and weight are most
visible in the first year of life and around puberty, both periods when a tremendous amount of
growth takes place in a short time. And to determine the percentage increment, percentage
difference of height, weight and BMI under the age group 13 to 18 years in both sexes. The
apparatus used to measure Height and weight was height measuring board mounted to weight
measuring in standing position following the standard steps. Across-sectional design method was
used and the data collected from direct measuring of the height and weight with bare foot and
light cloth.
The sample 400 students’ (equal proportion of males and females) were included in the study. The
results showed that the highest percentage increase of height for females (2.5%) was observed
during the transition between age 17 and18 while the lowest was (0.65%) which was observed
during the transition between age 15 and 16. For males, the highest height increase was 3.92%
during the transition between 14 and 15 year and the lowest was 1.26% observed between 15 and
16 year olds. The highest increment of bodyweight for females was 12.87% during the transition
between 13 and 14 years and the lowest was 0.2% between 15 and 16 year olds. For males, the
highest body weight increase was 8.54% between 14 and 15 years and the lowest was 2.07%
between 17 and 18 years. In females, BMI ranged from 18.15kg/m2 913 year old) to 22.59kg/m2
(17 year old). The highest percentage increment of BMI in female recorded between 13 and 14
years (10.83%) while the lowest was 0.1% recorded between 15 and 16 years. In males the
respective values were 6.2% (16 to 17 Years) and -1.1% (14 to 15 years).
The results compared to other studies with similar objectives and scope, the students from the
present study had significantly lower body weight than those from a private school in Addis
Ababa. However, based on their BMI values, all age categories of both sexes in the present study
fall under the normal weight category.
The final Conclusion of this study showed that there was no significant difference in height,
weight, and BMI between male’s females and all age groups of both sexes fall under the normal
weight category based on their mean BMI
