目的评估儿童肥胖与其父母的关系，并确定从童年到成年的肥胖跟踪是否根据父母的体重指数（BMI）而变化。方法：采用1958年英国出生队列研究的纵向数据（6540名男性和6207名女性）。研究对象在7岁、11岁、16岁、23岁（自我报告）和33岁时测量身高和体重。父母在孩子11岁时自我报告身高和体重。这些儿童被分为六个父母BMI（体重/身高）组。结果：在随访的各个年龄段，儿童的平均BMI随父母BMI的增加而增加。在父母超重或肥胖的儿童中，成年（33岁）肥胖的风险更高：父母都肥胖的子女（与父母体重指数正常的子女相比）的几率分别为8.4和6.8。父母都肥胖的孩子在7岁到33岁之间的BMI追踪也最强（r = 0.46, 0.54，分别为儿子和女儿）。结论：肥胖和超重父母的孩子患肥胖症的风险增加。父母双方都肥胖的受试者在童年时期更胖，并且从童年到成年也表现出更强的追踪模式。随着父母肥胖在普通人群中的患病率增加，从儿童到成人跟踪BMI的程度可能会加强。
Objectives-To assess relations between the adiposity of children and their parents and to establish whether tracking of adiposity from childhood to adulthood varies according to the parental body mass index (BMI).Methods-Longitudinal data from the 1958 British birth cohort study were used (6540 men and 6207 women). The height and weight of the study subjects were measured at 7, 11, 16, 23 (self reported), and 33 years. Parental height and weight were self reported when their children were 11 years old. The children were classified into six parental BMI (weight/height(2)) groups.Results-At each age of follow up the mean BMI of the children increased as the parental BMI increased. Higher risks of adult (33 year) obesity were evident among children with overweight-or obese parents: the odds for sons and daughters with two obese parents (compared with those with both parents of normal BMI) were 8.4 and 6.8, respectively. The children of two obese parents also showed the strongest child to adult tracking of BMI as indicated by the correlation between ages 7 and 33 (r = 0.46, 0.54, sons and daughters, respectively).Conclusions-The children of obese and overweight parents have an increased risk of obesity. Subjects with two obese parents are fatter in childhood and also show a stronger pattern of tracking from childhood to adulthood. As the prevalence of parental obesity increases in the general population the extent of child to adult tracking of BMI is likely to strengthen.
