The resemblance of dietary intakes in three generations of parent-offspring pairs: Tehran lipid and glucose study

Parent–child correlation in energy and macronutrient intakes: A meta‐analysis and systematic review

“…Our findings based on a meta‐regression showed that the resemblance of dietary intake between older children and their parents was lower than their younger counterparts; some previous investigations have suggested the considerable effects of factors outside the home as reasons for these results (Beydoun & Wang, 2009 ; Hosseini‐Esfahani et al., 2022 ). As children grow older, they spend more time outside the home and are more likely to be influenced by their peers.…”

“…Table 1 shows the data on the general characteristics of the 21 included articles (Adelekan & Adeodu, 1997; Beydoun & Wang, 2009; Bogl et al., 2017; Feunekes et al., 1997; Feunekes et al., 1998; Hosseini‐Esfahani et al., 2022; Lahmann et al., 2017; Laskarzewski et al., 1980; Lee & Park, 2015; Longbottom et al., 2002; Mitchell et al., 2003; Oliveria et al., 1992; Park et al., 2004; Pérusse et al., 1988; Rossow & Rise, 1994; Shrivastava et al., 2013; Stafleu et al., 1994; Stanton et al., 2003; Vauthier et al., 1996; Wang et al., 2009; Wroten et al., 2012). These studies were conducted in the USA ( n = 7) (Beydoun & Wang, 2009; Laskarzewski et al., 1980; Mitchell et al., 2003; Oliveria et al., 1992; Stanton et al., 2003; Wang et al., 2009; Wroten et al., 2012), Netherlands ( n = 3) (Feunekes et al., 1997; Feunekes et al., 1998; Stafleu et al., 1994), Korea ( n = 2) (Lee & Park, 2015; Park et al., 2004), UK ( n = 1) (Longbottom et al., 2002), Ireland ( n = 1) (Shrivastava et al., 2013), Nigeria ( n = 1) (Adelekan & Adeodu, 1997), Iran ( n = 1) (Hosseini‐Esfahani et al., 2022), Australia ( n = 1) (Lahmann et al., 2017), Norway ( n = 1) (Rossow & Rise, 1994), Canada ( n = 1) (Pérusse et al., 1988), Finland ( n = 1) (Bogl et al., 2017), and France ( n = 1) (Vauthier et al., 1996), and published in 1980 to 2022. The sample size in qualified studies evaluating the dietary resemblance among family members ranges from 33 to 4310.…”

“…with time. The influence of other people, such as peers, and also higher autonomy in food choices are factors that cause children who live apart from their parents to make possibly more changes in their food choices than those who live at home with parents (Hosseini-Esfahani et al, 2022;Lahmann et al, 2017;Zuercher et al, 2011).…”

“…This meta‐analysis of the findings of previous studies shows that family similarities in energy and macronutrient intake in mother–daughter pairs are somewhat stronger than in other parent–child pairs. Although the reasons for these findings are not fully known, some factors can justify this interesting finding (Hosseini‐Esfahani et al., 2022 ; Park et al., 2004 ; Wang et al., 2009 ); in most societies, mothers and daughters spend more time during the day than fathers and sons in the home environment and may have a greater joint role in the process of cooking and preparing food for the family's main meals and hence their food choices may be more similar in meals throughout a day (Hosseini‐Esfahani et al., 2022 ). However, sons may spend more time outside the home environment with peers and schoolmates, and under the influence of these people, they may have different food choices than their family and parents (Hosseini‐Esfahani et al., 2022 ; Park et al., 2004 ).…”

“…The overall lower dietary correlations reported in the children not living with their parents revealed that family resemblance and heritability in dietary intakes are not considerable in offspring living apart from their parents and can weaken with time. The influence of other people, such as peers, and also higher autonomy in food choices are factors that cause children who live apart from their parents to make possibly more changes in their food choices than those who live at home with parents (Hosseini‐Esfahani et al., 2022 ; Lahmann et al., 2017 ; Zuercher et al., 2011 ).…”
