This study aims to evaluate the association of birth weight (BW) with weight disorders in a national sample of Iranian pediatric population. This nationwide survey was conducted among 25000 student's aged 6-18 year-old students, who were selected using multistage cluster random sampling from 30 provinces of Iran in 2011-2012. Anthropometric measures were measured under standard protocols by using calibrated instruments. Abdominal obesity was defined based on waist circumference (WC) ≥90th percentile value for age and sex. The WHO criterion was used to categorize BMI. Students' BW was asked from parents using validate questionnaire and was categorized as low BW (LBW) (BW <2500 g), normal BW (NBW) (BW: 2500-4000 g) and high BW (HBW) (BW>4000 g). This national survey was conducted among 23043 school students (participation rate: 92.6%). The mean age of participants (50.8% boys) was 12.54 ± 3.31 years. Results of multivariate logistic regression show that LBW increased odds of underweight (OR [odds ratio]: 1.61; 95% CI: 1.37, 1.89) and students with HBW had decreased odds of underweight (OR: 0.74; 95% CI: 0.58, 0.93) compared to students with NBW. Students with LBW compared to student with NBW had decreased odds of overweight (OR: 0.83; 95% CI: 0.69, 0.98) and general obesity (OR: 0.73; 95% CI: 0.56, 0.95). On the other hand, HBW increased odd of overweight (OR: 1.28; 95% CI: 1.09, 1.50), generalized obesity (OR: 1.59; 95% CI: 1.29, 1.96) and abdominal obesity (OR: 1.29; 95% CI: 1.11, 1.49) compared to NBW group. BW is a determinant of weight disorders and abdominal obesity in childhood and adolescence. This finding underscores the importance of prenatal care as well as close monitoring of the growth pattern of children born with low or high BW.
本研究旨在评估伊朗儿童全国样本中出生体重（BW）与体重失调之间的关联。这项全国性调查在25000名6至18岁的学生中进行，这些学生于2011 - 2012年从伊朗30个省份通过多阶段整群随机抽样选取。人体测量指标是在标准方案下使用校准仪器测量的。腹部肥胖根据年龄和性别的腰围（WC）≥第90百分位数来定义。采用世界卫生组织标准对体重指数（BMI）进行分类。通过有效的问卷向家长询问学生的出生体重，并将其分为低出生体重（LBW）（BW <2500克）、正常出生体重（NBW）（BW：2500 - 4000克）和高出生体重（HBW）（BW>4000克）。这项全国性调查在23043名在校学生中进行（参与率：92.6%）。参与者的平均年龄为12.54 ± 3.31岁（男孩占50.8%）。多因素逻辑回归结果显示，与正常出生体重的学生相比，低出生体重增加了体重过轻的几率（比值比[OR]：1.61；95%置信区间：1.37, 1.89），而高出生体重的学生体重过轻的几率降低（OR：0.74；95%置信区间：0.58, 0.93）。与正常出生体重的学生相比，低出生体重的学生超重（OR：0.83；95%置信区间：0.69, 0.98）和总体肥胖（OR：0.73；95%置信区间：0.56, 0.95）的几率降低。另一方面，与正常出生体重组相比，高出生体重增加了超重（OR：1.28；95%置信区间：1.09, 1.50）、总体肥胖（OR：1.59；95%置信区间：1.29, 1.96）和腹部肥胖（OR：1.29；95%置信区间：1.11, 1.49）的几率。出生体重是儿童和青少年体重失调及腹部肥胖的一个决定因素。这一发现强调了产前护理以及密切监测低出生体重或高出生体重儿童生长模式的重要性。
