The prevalence of overweight and obesity among children and adults has risen in Canada. Studies suggest that parent obesity is a risk factor for overweight and obesity in children. This analysis examines associations between biological parent and child body mass index (BMI) in a nationally representative sample of Canadian children.
The analysis is based on data collected for 1,563 children aged 6 to 10 in the first three cycles of the Canadian Health Measures Survey (2007 to 2013). BMI was calculated using measured height and weight. Pearson correlation, logistic, and linear regression analyses examined associations between biological parent and child BMI and obesity status, controlling for other risk factors.
Biological parent and child BMI were correlated. When risk factors were taken into account, a child's average BMI increased as their parent's BMI increased. Parent BMI explained 2% of the variance in boys' BMI and 12% of the variance in girls' BMI. Boys and girls with a biological parent who was obese were at increased risk of being overweight or obese. Girls were also at increased risk of being overweight or obese if a biological parent was overweight.
Children's body weight status is associated with that of at least one of their biological parents. Having an obese parent increases the risk of overweight or obesity among children in Canada.
在加拿大，儿童和成年人超重和肥胖的患病率有所上升。研究表明，父母肥胖是儿童超重和肥胖的一个风险因素。本分析研究了在加拿大具有代表性的儿童样本中，亲生父母和儿童的身体质量指数（BMI）之间的关联。
该分析基于在加拿大健康衡量调查（2007 年至 2013 年）的前三个周期中收集的 1563 名 6 至 10 岁儿童的数据。BMI 是通过测量身高和体重计算得出的。采用皮尔逊相关、逻辑和线性回归分析，在控制其他风险因素的情况下，检验了亲生父母和儿童 BMI 与肥胖状况之间的关联。
亲生父母和儿童的 BMI 呈正相关。当考虑到风险因素时，儿童的平均 BMI 随父母 BMI 的增加而增加。父母 BMI 解释了男孩 BMI 方差的 2%和女孩 BMI 方差的 12%。亲生父母肥胖的男孩和女孩超重或肥胖的风险增加。如果亲生父母超重，女孩超重或肥胖的风险也会增加。
儿童的体重状况与其至少一位亲生父母的体重状况有关。在加拿大，肥胖父母会增加儿童超重或肥胖的风险。
