Ethnic background and television viewing time among 4-year-old preschool children: the generation R study.

OBJECTIVE: Children's television viewing has been associated with an increased risk of overweight and obesity. This study aims to assess the associations of ethnic background and acculturation characteristics with television viewing time in 4-year-old preschool children.
METHOD: The authors analyzed data from 3452 preschool children and their parents enrolled in the Generation R Study, a large, multiethnic, prospective birth cohort study in Rotterdam, the Netherlands. Multivariable logistic regression models were used to estimate odds ratios of watching television ≥2 hours/day and ≥1 hour/day for Turkish, Moroccan, and Surinamese children (reference group: native Dutch children), adjusted for family socioeconomic position. Effect modification by family socioeconomic position was also assessed.
RESULTS: After adjustment for family socioeconomic position, Turkish children (adjusted odds ratio [aOR], 2.27; 95% confidence interval [CI], 1.56-3.30), Moroccan children (aOR, 1.68; 95% CI, 1.03-2.76), and Surinamese children (aOR, 3.12; 95% CI, 2.16-4.50) were significantly more likely to watch television ≥2 hours/day compared with native Dutch children. Stratified analyses showed greater disparity between ethnic minority groups and native Dutch children at higher educational levels. There were no significant associations between acculturation characteristics (i.e., generational status, age at immigration, and Dutch language skills) and children's television viewing time.
CONCLUSION: Children from ethnic minority groups are at an increased risk for high levels of television viewing compared with native Dutch children, independent of family socioeconomic position. Interventions aimed to reduce television viewing time should target all children from ethnic minority groups.
