Adverse parental life-style habits are associated with offspring adiposity, but it is unclear how changes in these habits affect offspring adiposity. Thus, the aim of this study was to assess how parental change in body weight, smoking habits and levels of physical activity were associated with adiposity in their children.
The study population consisted of 3 681 adolescents and their parents from the Nord-Trøndelag-Health-Study (HUNT). The parents participated in the two first waves of HUNT (HUNT-1:1984-86, HUNT-2:1995-97), where information on anthropometry, smoking habits and physical activity were obtained. The adolescents participated in the Youth-Part of HUNT-2. We used logistic regression to calculate odds-ratios (ORs) for adolescent offspring overweight according to parental change in body-weight, smoking habits and physical activity, adjusting for these factors in both parents, as well as for socioeconomic status and adolescent age and sex.
Children of parents who changed weight from normal weight to overweight from HUNT-1 to HUNT-2 had higher OR for overweight in adolescence than children of parents who remained normal weight (mothers: 1.9 [95% CI: 1.4,2.5], fathers: 2.2 [95% CI: 1.5,3.0]). Children of mothers who reduced their weight from overweight to normal weight had no higher OR for overweight in adolescence than mothers who remained normal weight (OR: 1.0; 95% CI: 0.2, 4.7). Children of mothers who quit smoking (OR: 0.5; 95% CI: 0.3, 0.8) had lower OR for overweight in adolescence than children of mothers who persisted in smoking.
Healthy changes in parental life-style during childhood are associated with lower occurrence of offspring overweight in adolescence.
父母不良的生活方式习惯与子代肥胖有关，但尚不清楚这些习惯的改变如何影响子代肥胖。因此，本研究的目的是评估父母体重、吸烟习惯和身体活动水平的变化与子女肥胖之间的关联。
研究人群包括来自北特伦德拉格健康研究（HUNT）的3681名青少年及其父母。父母参与了HUNT的前两波调查（HUNT-1：1984 - 1986年，HUNT-2：1995 - 1997年），在这两轮调查中获取了人体测量、吸烟习惯和身体活动方面的信息。青少年参与了HUNT-2的青少年部分。我们使用逻辑回归，根据父母体重、吸烟习惯和身体活动的变化，计算青少年子代超重的比值比（OR），同时对父母的这些因素、社会经济地位以及青少年的年龄和性别进行校正。
从HUNT-1到HUNT-2体重从正常变为超重的父母，其子女在青春期超重的OR高于体重保持正常的父母的子女（母亲：1.9 [95% CI：1.4, 2.5]，父亲：2.2 [95% CI：1.5, 3.0]）。体重从超重减至正常的母亲，其子女在青春期超重的OR并不高于体重保持正常的母亲（OR：1.0；95% CI：0.2, 4.7）。戒烟母亲的子女在青春期超重的OR低于持续吸烟母亲的子女（OR：0.5；95% CI：0.3, 0.8）。
儿童时期父母生活方式的健康改变与青春期子代超重发生率较低有关。
