The home environment is likely to influence children's diet and activity patterns and ultimately, their weight trajectories. Identifying family characteristics associated with a more 'obesogenic' home can provide insight into the determinants, and has implications for targeting and tailoring strategies to promote healthier lifestyles. The present study examined maternal characteristics associated with a more obesogenic home environment in 1113 families with preschool children. Primary caregivers (99% mothers) from the Gemini cohort completed the Home Environment Interview (HEI) when their children were 4 years old. Maternal demographics and BMI were assessed in the Gemini baseline questionnaire when the children were on average 8 months old. Maternal eating style was assessed when the children were on average 2 years old, using the Dutch Eating Behaviour Questionnaire (DEBQ). Responses to the HEI were standardised and summed to create a composite score of the obesogenic quality of the home; this was categorised into tertiles. Multivariate ordinal logistic regression showed that mothers who were younger (adjusted OR; 95% CI = 0.96; 0.94-0.98), less educated (1.97; 1.40-2.77), and had lower incomes (1.89; 1.43-2.49) at baseline were more likely to live in an obesogenic home environment at 4 years, as were mothers who scored higher on the DEBQ External Eating scale (1.40; 1.16-1.70) at 2 years, and had a higher baseline BMI (1.05; 1.02-1.08). Using a novel, composite measure of the home environment, this study finds that families who are more socio-economically deprived, and where the mothers are themselves heavier and have a more food responsive eating style, tend to provide a home environment with the hallmarks of a higher risk of weight gain.
家庭环境可能会影响儿童的饮食和活动模式，并最终影响他们的体重轨迹。识别与更具“致肥胖性”家庭相关的家庭特征，可以深入了解其决定因素，并对制定和调整促进更健康生活方式的策略具有启示意义。本研究调查了1113个有学龄前儿童家庭中与更具致肥胖性家庭环境相关的母亲特征。双子座队列中的主要照料者（99%为母亲）在其孩子4岁时完成了家庭环境访谈（HEI）。当孩子平均8个月大时，在双子座基线问卷中评估母亲的人口统计学特征和体重指数（BMI）。当孩子平均2岁时，使用荷兰饮食行为问卷（DEBQ）评估母亲的饮食风格。对HEI的回答进行标准化并求和，以创建家庭致肥胖性质量的综合得分；该得分被分为三个等级。多变量有序逻辑回归显示，基线时年龄较小（调整后的比值比；95%置信区间=0.96；0.94 - 0.98）、受教育程度较低（1.97；1.40 - 2.77）、收入较低（1.89；1.43 - 2.49）的母亲，在孩子4岁时更有可能生活在致肥胖性家庭环境中，2岁时在DEBQ外部饮食量表上得分较高（1.40；1.16 - 1.70）以及基线BMI较高（1.05；1.02 - 1.08）的母亲也是如此。通过使用一种新颖的家庭环境综合测量方法，本研究发现，社会经济条件较差、母亲自身体重较重且饮食风格对食物反应性更强的家庭，往往提供具有体重增加风险较高特征的家庭环境。
