Tween sex differences in snacking preferences during television viewing.

Television viewing is associated with an increased risk in childhood obesity. Research surrounding food habits of tweens largely bypasses snacking preferences while watching television in the home. The aim of this cross-sectional study was to describe snacking prevalence by tween sex and to describe parental rules surrounding snacking while watching television at home. Survey data were obtained in 2008 from 4th- through 6th-grade students (n=1,557) who attended 12 New England schools. Complete self-reported measures (n=1,448) included demographics, household and bedroom television ownership, television watching frequency, snacking prevalence, snacking preferences, and parental rules regarding snacking while watching television. Comparisons were generated using χ(2) analyses. Overall, the majority of children (69.2%) snacked "sometimes" or "always" during television viewing, with the majority of responses (62.9%) categorized as foods. The most popular food snacks for both sexes in this sample were salty snacks (47.9%), with fruits and vegetables ranking a distant second (18.4%). Girls (22.6%) selected fruits and vegetables more frequently than boys (14.7%) (P=0.003). Of those drinking beverages (n=514), boys selected sugar-sweetened beverages more often than girls (43.5% vs 31.7%; P=0.006), and girls chose juice more often than boys (12.3% vs 6.1%; P=0.02). Overall, approximately half (53.2%) of the students consumed less-healthy snacks while watching television. Interventions for parents and both sexes of tweens focusing on healthy snacking choices may have long-term beneficial outcomes.
