If expectant mothers are exposed to stress their child can develop behavioural problems – but this is less often the case for children with siblings 妊婦がストレスにさらされると、子どもが問題行動を起こす可能性がある-ただし、きょうだいのいる子どもはその可能性が低い

ライプチヒ大学とマックスプランク進化人類学研究所のフェデリカ・アミーチは、「これらの結果は、軽い胎内ストレスであっても、数年後には子供の行動に悪影響を及ぼす可能性があるというこれまでの知見を裏付けるものであり、母親の幸福感を高め、妊娠中にすでに母親のストレスのリスクを軽減する早期介入政策の重要性を強調する」と説明している。
さらに、この研究では、年上の兄弟がいる子どもは、行動上の問題が少ないことも明らかになった。LINA研究のコーディネーターであるヘルムホルツ環境研究センターのグンダ・ヘルバース氏は、「家庭に兄や姉がいる子どもは問題を起こす可能性が低く、子どもの健全な成長を促進するために兄姉が重要であることを示唆しています」と説明している。

Abstract
Background
In the first years of their lives, children develop the cognitive, social and emotional skills that will provide the foundations for their lifelong health and achievements. To increase their life prospects and reduce the long-term effects of early aversive conditions, it is therefore crucial to understand the risk factors that negatively affect child development and the factors that are instead beneficial. In this study, we tested (i) the effects of different social and environmental stressors on maternal stress levels, (ii) the dynamic relationship between maternal stress and child behavior problems during development, and (iii) the potential promotive (i.e. main) or protective (i.e. buffering) effect of siblings on child behavior problems during development.
Methods
We used longitudinal data from 373 mother–child pairs (188 daughters, 185 sons) from pregnancy until 10 years of age. We assessed maternal stress and child behavior problems (internalizing and externalizing) with validated questionnaires, and then used linear mixed models, generalized linear mixed models and longitudinal cross-lagged models to analyze the data.
Results
Our results showed that higher maternal stress levels were predicted by socio-environmental stressors (i.e. the lack of sufficient social areas in the neighborhood). Moreover, prenatal maternal stress reliably predicted the occurrence of behavior problems during childhood. Finally, the presence of older siblings had a promotive function, by reducing the likelihood that children developed externalizing problems.
Conclusions
Overall, our results confirm the negative effects that maternal stress during pregnancy may have on the offspring, and suggest an important main effect of older siblings in promoting a positive child development.
