A Nutritional Study on Weight Status among Urban Male High School Students and Its Related Determinants in Urmia, IRAN

Several studies have so far been carried out to determine the prevalence of
overweight and obesity among Iranian children but few studies have investigated the relationship between
eating habits, socio-demographic differentials and obesity in these children. So, this study tried to assess the
body weight status among the urban high school boy students of Urmia, Iran.
Materials and Methods: In this cross-sectional study, we measured weight, height and BMI of 1026 boy
students with an age range of 15 to 19 years by multi-stage sampling. Then a questionnaire was completed
based on their dietary habits and behaviors related to their physical activity. Overweight and obesity were
defined based upon the World Health Organization’s growth charts. Statistical analysis was fulfilled by
estimating absolute and relative frequencies.
Results: Underweight prevalence in the studied population was 9.84% (95% CI: 8.49%-10.72%). The
prevalence of overweight and obesity among the studied students was 12.77% (95% CI: 11.89%-13.3%), and
5.07% (95% CI: 4.5%-5.9%), respectively. Factors significantly correlated with the participants' body weight
were the frequency of energy dense foods intake during a week (P<0.001), duration of computer use per day
(P<0.01), and the kind of their schools (P<0.05). No significant association was found between other studied
dietary variables (such as the time spent for eating over 24-hours, and breakfast eating times per week) and
overweight/obesity.
Conclusions: In the present study, we found that two changeable parameters (i.e. the number of times for
intake of energy dense foods during a week, and working with computers) could influence the 15-19 years old
school boys' body weight in the study region
