Abstract

OBJECTIVES

To investigate the impact of grandparent's co-residence and dietary knowledge on the overweight and obesity risk among school-age children in China.

METHODS

Data of 790 children aged 7-15 years were retrieved from the China Health and Nutrition Survey (CHNS). Co-residential status was evaluated using household and individual ID. Dietary knowledge was assessed using 17 dietary statements, which was scored by participants. Three principal factors were extracted by factor analysis. Logistic regression analysis was applied to examine the influence of grandparent's co-residence and dietary knowledge on the weight status of the child.

RESULTS

The overweight and obesity incidence of the children increased significantly when they co-reside with two grandparents (OR=1.447, 95CI: 1.001-2.090, p=0.049). Mother's dietary knowledge regarding to protein-related food choices (PT) scored higher was associated with the increased risk (OR=1.270, 95CI: 1.059-1.523, p=0.010). For grandmother's dietary knowledge, the higher score in balanced food consumption (BF) was associated with the decreased overweight and obesity risk (OR=0.456, 95CI: 0.294-0.706, p<0.001). Grandfather's dietary knowledge in BF showed the similar result (OR=0.454, 95CI: 0.271-0.759, p=0.003).

CONCLUSIONS

Living with two grandparents is associated with higher overweight and obesity risk, but grandparents with an adequate knowledge in the balanced food consumption may decrease the risk.

摘要

目的

研究祖辈共同居住和饮食知识对中国学龄儿童超重和肥胖风险的影响。

方法

从中国健康与营养调查（CHNS）中检索到 790 名 7-15 岁儿童的数据。使用家庭和个人 ID 评估共同居住状况。饮食知识通过 17 项饮食陈述进行评估，参与者对其进行评分。通过因子分析提取三个主要因子。应用逻辑回归分析来检验祖辈共同居住和饮食知识对儿童体重状况的影响。

结果

当孩子与两位祖辈共同居住时，其超重和肥胖发生率显著增加（OR=1.447，95CI：1.001-2.090，p=0.049）。母亲关于蛋白质相关食物选择（PT）的饮食知识得分越高，风险越高（OR=1.270，95CI：1.059-1.523，p=0.010）。对于祖母的饮食知识，平衡食物消费（BF）的高分与超重和肥胖风险降低相关（OR=0.456，95CI：0.294-0.706，p<0.001）。祖父在 BF 方面的饮食知识也显示出类似的结果（OR=0.454，95CI：0.271-0.759，p=0.003）。
