Abstract

OBJECTIVES

To examine the association between mealtime media use and non-HDL-cholesterol as well as other markers of cardiometabolic risk (CMR) in children.

DESIGN

A repeated measures study design was used to examine the association between mealtime media use and CMR outcomes. Multivariable linear regression with generalised estimating equations was used to examine the association between mealtime media use and CMR outcomes. Analyses were stratified a priori by age groups (1-4 and 5-13 years).

SETTING

The TARGet Kids! Practice-based research network in Toronto, Canada.

PARTICIPANTS

2117 children aged 1-13 years were included in the analysis.

RESULTS

After adjusting for covariates, there was no evidence that total mealtime media use was associated with non-HDL-cholesterol in 1-4 year olds (P = 0·10) or 5-13 year olds (P = 0·29). Each additional meal with media per week was associated with decreased HDL-cholesterol in 5-13 year olds (-0·006 mmol/l; 95 % CI -0·009, -0·002; P = 0·003) and log-TAG in 1-4 year olds (β = -0·004; 95 % CI -0·008, -0·00009; P = 0·04). Media use during breakfast was associated with decreased HDL-cholesterol in 5-13 year olds (-0·012 mmol/l; 95 % CI -0·02, -0·004; P = 0·002), while media during lunch was associated with decreased log-TAG (-0·01 mmol/l; 95 % CI -0·03, -0·002; P = 0·03) in children aged 1-4 years. Total mealtime media use was not associated with total cholesterol, glucose or insulin in either age group.

CONCLUSIONS

Mealtime media use may be associated with unfavourable lipid profiles through effects on HDL-cholesterol in school-aged children but likely not in pre-schoolers.

摘要

目的

研究进餐时使用媒体与非高密度脂蛋白胆固醇（non-HDL-cholesterol）及儿童心血管代谢风险（cardiometabolic risk，CMR）其他标志物之间的关系。

设计

采用重复测量研究设计，观察进餐时使用媒体与 CMR 结局之间的关系。采用广义估计方程的多变量线性回归，观察进餐时使用媒体与 CMR 结局之间的关系。根据年龄组（1-4 岁和 5-13 岁）进行预先分层分析。

地点

加拿大多伦多的 TARGet Kids！基于实践的研究网络。

参与者

2117 名 1-13 岁儿童纳入分析。

结果

在调整了协变量后，在 1-4 岁儿童（P = 0·10）和 5-13 岁儿童（P = 0·29）中，并未发现总的进餐时媒体使用与非高密度脂蛋白胆固醇有关。每周每多一顿含媒体的餐与 5-13 岁儿童的高密度脂蛋白胆固醇降低有关（-0·006 mmol/L；95 % CI -0·009，-0·002；P = 0·003），与 1-4 岁儿童的 log-TAG 降低有关（β = -0·004；95 % CI -0·008，-0·00009；P = 0·04）。在 5-13 岁儿童中，早餐时使用媒体与高密度脂蛋白胆固醇降低有关（-0·012 mmol/L；95 % CI -0·02，-0·004；P = 0·002），而在 1-4 岁儿童中，午餐时使用媒体与 log-TAG 降低有关（-0·01 mmol/L；95 % CI -0·03，-0·002；P = 0·03）。在两个年龄组中，总的进餐时媒体使用与总胆固醇、血糖或胰岛素均无关。
