Children in low-income Hispanic families are at high risk of obesity and are more likely to live with grandparents than their non-Hispanic white counterparts. We aimed to determine if grandparent coresidence (prenatal through age 2 years) was associated with: 1) obesogenic feeding practices; and 2) child weight outcomes from birth to three years. We analyzed data from 267 low-income, Hispanic mother-infant pairs in the control group of an obesity prevention trial in New York City. Linear and logistic regression tested differences in obesogenic feeding practices and weight outcomes at 2 and 3 years, dependent upon grandparent coresidence. Multilevel modeling tested associations between grandparent coresidence and WFAz over time. Persistent grandparent coresidence (vs none) was associated with putting cereal in the bottle (adjusted odds ratio [aOR] 3.46; 95% confidence interval [CI] 1.43, 8.40). Persistent grandparent coresidence (vs none) was associated with higher mean WFAz (2 years: B 0.83; 95% CI 0.41, 1.25; 3 years: B 0.79; 95% CI 0.32, 1.25) and higher odds of child overweight/obesity risk (2 years: aOR 4.38; 95% CI 1.64, 11.69; 3 years: aOR 3.15; 95% CI 1.19, 8.36). In multilevel models, more occasions of grandparent coresidence were associated with higher WFAz. Grandparent coresidence may be associated with higher risk of child overweight/obesity in low-income, Hispanic families. Further research is needed to elucidate mechanisms of these associations and to inform obesity prevention strategies in the context of multigenerational families.

纽约市低收入西班牙裔家庭的祖父母同居和幼儿超重和肥胖的风险


低收入西班牙裔家庭的儿童肥胖的风险很高，并且比非西班牙裔白人儿童更有可能与祖父母住在一起。我们的目的是确定祖父母同住（产前至 2 岁）是否与以下因素相关：1）导致肥胖的喂养方式； 2) 从出生到三岁的儿童体重结果。我们分析了纽约市一项肥胖预防试验对照组中 267 对低收入拉美裔母婴的数据。线性和逻辑回归测试了 2 和 3 岁时肥胖喂养方式和体重结果的差异，具体取决于祖父母同住。多层次模型测试了祖父母同居与 WFAz 之间随时间变化的关联。持续与祖父母同住（对比没有）与将麦片放入瓶中有关（调整后的比值比 [aOR] 3.46；95% 置信区间 [CI] 1.43, 8.40）。持续与祖父母同住（与无祖父母同住）与较高的平均 WFAz（2 年：B 0.83；95% CI 0.41, 1.25；3 年：B 0.79；95% CI 0.32, 1.25）和儿童超重/肥胖风险较高的几率相关（ 2 年：aOR 4.38；95% CI 1.64，11.69；3 年：aOR 3.15；95% CI 1.19，8.36。在多层次模型中，祖父母同住的次数越多与 WFAz 越高相关。在低收入西班牙裔家庭中，祖父母同住可能与儿童超重/肥胖的风险较高有关。需要进一步的研究来阐明这些关联的机制，并为多代家庭背景下的肥胖预防策略提供信息。
