This cross-sectional study was carried out to determine the prevalence of overweight and obesity among secondary school children aged 12 to 14 years in the city of Mashhad, Iran and its association with parental body mass index.
A total of 1189 secondary school children (579 males and 610 females) aged 12- 14 years old were selected through a stratified multistage random sampling. All adolescents were measured for weight and height. Household socio-demographic information and parental weight and height were self-reported by parents. Adolescents were classified as overweight or obese based on BMI-for age Z-score. Multivariable logistic Regression (MLR) determined the relationship between parental BMI and adolescent overweight and obesity.
The overall prevalence of overweight and obesity among secondary school children in Mashhad was 17.2% and 11.9%, respectively. A higher proportion of male (30.7%) than female (27.4%) children were overweight or obese. BMI of the children was significantly related to parental BMI (p<0.001), gender (p= 0.02), birth order (p<0.01), parents' education level (p<0.001), father's employment status (p<0.001), and family income (p<0.001). MLR showed that the father's BMI was significantly associated with male BMI (OR: 2.02) and female BMI (OR: 1.59), whereas the mother's BMI was significantly associated with female BMI only (OR: 0.514).
The high prevalence of overweight/obesity among the research population compared with previous studies in Iran could be related to the changing lifestyle of the population. The strong relationship with parental BMI was probably related to a combination of genetic and lifestyle factors. Strategies to address childhood obesity should consider the interaction of these factors.
本横断面研究旨在确定伊朗马什哈德市12至14岁中学生中超重和肥胖的患病率及其与父母体重指数的关联。
通过分层多阶段随机抽样选取了1189名12 - 14岁的中学生（579名男生和610名女生）。测量了所有青少年的体重和身高。父母自行报告家庭社会人口学信息以及父母的体重和身高。根据年龄别BMI Z评分将青少年分为超重或肥胖。多变量逻辑回归（MLR）确定父母BMI与青少年超重和肥胖之间的关系。
马什哈德市中学生中超重和肥胖的总体患病率分别为17.2%和11.9%。超重或肥胖的男孩比例（30.7%）高于女孩（27.4%）。儿童的BMI与父母BMI（p<0.001）、性别（p = 0.02）、出生顺序（p<0.01）、父母教育水平（p<0.001）、父亲就业状况（p<0.001）和家庭收入（p<0.001）显著相关。MLR显示，父亲的BMI与男性BMI（OR：2.02）和女性BMI（OR：1.59）显著相关，而母亲的BMI仅与女性BMI显著相关（OR：0.514）。
与伊朗以往研究相比，研究人群中超重/肥胖的高患病率可能与人群生活方式的改变有关。与父母BMI的密切关系可能与遗传和生活方式因素的综合作用有关。应对儿童肥胖的策略应考虑这些因素的相互作用。
