“…A large and growing body of research has suggested that in utero and childhood risk factors may contribute to health in later life. These risk factors, including poor health in childhood ( Gong et al, 2015 ; Kendig et al, 2017 ; Wang & Shen, 2016 ; Wang et al, 2018a ), limited access to healthcare ( Zeng et al, 2007 ), low parental socioeconomic status ( Zhang & Crimmins, 2018 ), childhood adversities ( Tian et al, 2019 ; Yang & Lou, 2016 ), low residential mobility ( Xu et al, 2019 ), malnutrition ( Zhang et al, 2018a ), lack of social support ( Zhang et al, 2018 ), low education and cognitive stimulation ( Langa & Larson, 2014 ), unfavorable sibling sex-composition such as daughters growing up in families with sons ( Huang & Elo, 2009 ), and negative parent-child relationship ( Zhang et al, 2018 ), have been found to contribute to individuals’ susceptibility to mental health problems, chronic diseases, functional and cognitive impairment, and premature death in China. The association between mid-life lifestyle factors and late-life physical and mental health status has also been established ( Lafortune et al, 2016 ; Sun et al, 2009 ; Tyas et al, 2003 ).…”
