Abstract:
Background: Obesity in early life has a greater tendency to follow through adulthood
and it will end up with serious medical problems, lower educational attainment and
higher rates of poverty. However there is paucity of available information regarding
the adolescents’ overweight and obesity in Ethiopia, particularly in the study area.
Objective: To determine prevalence of overweight and obesity and associated factors
among school adolescents in Jimma town. Methods: School based cross-sectional
study was conducted from March to April/2015 among 546 adolescents selected using
multi stage stratified random sampling. An interviewer administered questionnaire
was used to collect socio demographic, dietary intake, health risky behaviour, and
physical activity characteristics of the participants and weight & height were
measured using calibrated equipment’s and standardized techniques. Data were
analysed using SPSS v20 and WHO Anthro Plus. Multivariable logistic regression
was used to isolate independent predictors of overweight and obesity at 95%
confidence intervals. RESULTS: The prevalence of overweight/obesity was 13.3%
(overweight (11.8%) and obese (1.6%)). Girls are 3.57(Adjusted odd ratio(AOR=3.57
[95%; CI:1.28-9.9] times more likely to be overweight/obese, additional year in age
of the adolescents lowers the odds of overweight by 28.9% (AOR=0.71[0.53-0.95]),
private school adolescents are 7.53 times(AOR=7.53[2.51-22.3]) more likely to be
overweight/obese, Adolescents whose father did not attend formal education are 5.57
times(AOR=5.57[1.53-20.26]) more likely to be overweight/obese than whose father
attended college & above. Those from high wealth quintile households (HH) are 3
times (AOR=3[1.094-8.26]) more likely to be overweight/obese than those from
lower wealth quintile HHs. Adolescents who did not consume fruit are 5
times(AOR=5.08[1.57-16.38]) and who did not consume vegetables are 9
times(AOR=9.23[1.68-50.8]) more likely to be overweight/obese as than who
consume 5-7x/wk. and adolescent who did not consume animal source foods(ASF)
had 96.2%(AOR=0.038[0.006-0.24]) lower odds than who consume 5-7x/wk. Those
who are physically inactive are 3.7 times (AOR=3.7[1.06-13.02)]) and those involved
in sedentary behaviour for ≥3hr in day are 3.64[1.39-9.5] more likely to be
obese/overweight than their counter peers. Conclusion and recommendation:
Prevalence of overweight/obesity among Jimma town school adolescent is
considerably high. Being female, younger age, learning in private school, lower
paternal education, high HH wealth, limited fruit and vegetable consumption and
frequent ASF consumption, physical inactivity and sedentary behavior were
significantly associated with overweight/obesity and early interventions strategies that
address certain socioeconomic and life style related factors needs to be established.
