Parents' physical activity associates with their children's physical activity. Prospective designs assessing this association are rare. This study examined how parents' physical activity was associated with their children's physical activity from childhood to middle adulthood in a 30-year prospective, population-based setting.
Participants (n = 3596) were from the ongoing Cardiovascular Risk in Young Finns study started in 1980. Participants' physical activity was self-reported at 8 phases from 1980 to 2011, and their parents' physical activity at 1980. Analyses were adjusted for a set of health-related covariates assessed from 1980 to 2007.
High levels of mothers' and fathers' physical activity were systematically associated with increased levels of their children's physical activity until offspring's age of 24. Longitudinal analyses conducted from 1980 to 2011 showed that higher levels of parents' physical activity were associated with increased levels of physical activity within their offspring until midlife, but the association between parents' and their children's physical activity weakened when participants aged (P < .05). Covariate adjustment did not attenuate the association.
This study suggests that parents' physical activity assessed in their offspring's childhood contributes favorably to offspring's physical activity from childhood to middle age.
父母的身体活动与子女的身体活动相关。评估这种关联的前瞻性研究设计很少见。本研究在一项为期30年的基于人群的前瞻性研究中，考察了从童年到中年，父母的身体活动如何与子女的身体活动相关。
参与者（n = 3596）来自始于1980年的正在进行的芬兰年轻人心血管风险研究。参与者的身体活动在1980年至2011年的8个阶段进行自我报告，其父母的身体活动在1980年进行报告。分析针对1980年至2007年评估的一系列与健康相关的协变量进行了调整。
母亲和父亲的高水平身体活动与子女在24岁之前身体活动水平的增加系统相关。1980年至2011年进行的纵向分析表明，父母较高水平的身体活动与子女中年之前身体活动水平的增加相关，但当参与者年龄增长时，父母与子女身体活动之间的关联减弱（P <.05）。协变量调整并未减弱这种关联。
本研究表明，在子女童年时期评估的父母身体活动对子女从童年到中年的身体活动有积极贡献。
