Food and beverage cues in UK and Irish children—television programming

Objectives Increased time in which children spend watching television is a well-described contributor to paediatric obesity. This study investigated the frequency and type of food and beverage placement in children-specific television broadcasts and compared data from UK (UK) and Irish television stations. Design Content analysis, totalling 82.5 h, reflecting 5 weekdays of children-specific television broadcasting on UK and Irish television channels was performed. To allow comparison between UK and Irish food and beverage cues, only broadcasts between 06.00 and 11.30 were analysed. Data were coded separately by two analysts and transferred to SPSS for analyses. Food and beverage cues were coded based on type of product, product placement, product use, motivation, outcome and characters involved. Results A total of 1155 food and beverage cues were recorded. Sweet snacks were the most frequent food cue (13.3%), followed by sweets/candy (11.4%). Tea/coffee was the most frequent beverage cue (13.5%), followed by sugar-sweetened beverages (13.0%). The outcome of the cue was positive in 32.6%, negative in 19.8%, and neutral in 47.5% of cases. The most common motivating factor associated with each cue was celebratory/social (25.2%), followed by hunger/thirst (25.0%). Comparison of UK and Irish placements showed both to portray high levels of unhealthy food cues. However, placements for sugar-sweetened beverages were relatively low on both channels. Conclusions This study provides further evidence of the prominence of unhealthy foods in childrens programming. These data may provide guidance for healthcare professionals, regulators and programme makers in planning for a healthier portrayal of food and beverage in childrens television.

The Development of Activity Profiles in Adolescent Females and their Association with Adiposity

OBJECTIVES This study aims to (1) use the objective activPAL activity monitor to assess physical activity behaviors, including sitting/lying, standing, and both light (LIPA) and moderate-to-vigorous physical activity (MVPA); (2) to develop distinct activity profiles based on time spent in each behavior in a sample of adolescent females; and (3) examine whether levels of adiposity differ across these activity profiles. METHODS Female adolescents (n = 195; 14-18 y) had body mass index (median = 21.7 [IQR = 5.2] kg/m2) and 4-site skinfold thickness (median 62.0 mm; IQR = 37.1) measured. Physical activity behaviors were measured using the activPAL. Hierarchical cluster analysis grouped participants into activity profiles based on similar physical activity characteristics. Linear mixed models explored differences in body composition across activity profiles. RESULTS Three activity profiles were identified, a low (n = 35), moderate (n = 110), and a high activity profile (n = 50). Significant differences across activity profiles were observed for skinfold thickness (p = .046), with higher values observed in the low activity profile compared with the high activity profile. CONCLUSIONS Profiling free-living activity using behaviors from across the activity intensity continuum may account for more of the variability in energy expenditure then examining specific activity intensities, such as MVPA alone. The use of activity profiles may enable the identification of individuals with unhealthy activity behaviors, leading to the development and implementation of more targeted interventions.

Exercise portrayal in children’s television programs: analysis of the UK and Irish programming

Background Television watching is obesogenic due to its sedentary nature and programming content, which influences children. Few studies have examined exercise placement within children-specific programming. This study aimed to investigate the frequency and type of exercise placement in children-specific television broadcasts and to compare placements on the UK and Irish television channels. Methods Content analysis for five weekdays’ worth of children-specific television broadcasting totaling 82.5 hours on both the UK (British Broadcasting Corporation) and Irish (Radió Teilifís Éireann) television channels was performed. For the purposes of comparing the UK and Irish placements, analysis was restricted to programming broadcast between 6 am and 11.30 am. Exercise placements were coded based on type of activity, activity context, activity motivating factors and outcome, and characters involved. Results A total of 780 cues were recorded during the total recording period. A wide variety of sports were depicted, but dancing-related cues were most commonly seen (n=163, 23.3%), with the majority of cues being of mild (n=365, 65.9%) or moderate (n=172, 31.0%) intensity. The majority of cues were associated with a positive outcome (n=404, 61.4%), and social motivations were most commonly seen (n=289, 30.3%). The Irish and the UK portrayals were broadly similar. Conclusion This study highlights the wide variety of sports portrayed and the active effort undertaken by television stations to depict physical exercise and recreation in a positive light.

Children in hospital in Ireland - what do they eat and what do they weigh: a cross-sectional study

BackgroundOverweight and obesity is a growing problem in Ireland. Many parents are unaware when their child is overweight or obese. Our objectives were to examine parents’ perceptions of a healthy diet and their children’s BMI; and to evaluate the food offered to children in our paediatric in-patient unit.FindingsA retrospective questionnaire was distributed to 95 patients and their families admitted over one month. Seventy-eight had BMI values calculated (42 males, 36 females). Twenty-one children (26.9%) were overweight/obese: 14/21 parents (66.7%) thought their child had a normal weight. Sixty percent of children served dinner in the hospital were given fried potatoes. Four had fruit/vegetables. Forty-six parents brought food into hospital, of these 14 brought purchased food.ConclusionsThis study highlights the problem of child obesity in Ireland and parental underestimation of this problem. The nutritional value of food served to children in hospital needs to be improved and hospital admissions used as opportunities to promote healthy eating habits.
