OBJECTIVE: The purpose of this study was to analyze children's television viewing habits and their parents attitudes towards such viewing. DESIGN: Cross-sectional descriptive study. SETTING: Primary care. PARTICIPANTS: A survey was undertaken with 317 three to fourteen year old children and their parents as part of the primary care check-up program for healthy children. MEASUREMENTS AND MAIN RESULTS: Time devoted to television viewing was 106 +/- 50 minutes on weekdays and 141 +/- 80 minutes weekends. Despite this, 49.2% of parents thought their children saw little television, especially those with children under six (57.6%). Children of parents in highly qualified positions and of parents in the uppermost socioeconomic group saw television the least, on non-working days (70 +/- 61 minutes and 144 +/- 78 minutes respectively, p < or = 0.0001). Some 71.9% of children watched television alone and 34% did so at meal-times. Altogether 48.3% of parents were unaware as to what their children watched and some 61.5% encouraged television viewing, above all those having children of under six (76%). The youngest children preferred to watch cartoons which were generally of a violent nature. For those aged from 11 to 14, 19.5% chose as their favorite programs those having a high level of violence. CONCLUSION: Television habits are an educational problem for parents, an important shake-up in their attitudes being called for, in which pediatricians should be involved in developing health programs aimed at proper use of the television.
Two similar, but not identical, content analyses of the portrayals of men and women in French and Danish television advertisements are reported. By partially replicating and extending past investigations conducted in America, Australia, Britain, Hong Kong, Indonesia, Italy, Kenya, and New Zealand, it was predicted that there would be more gender stereotyping in French television advertisements and less gender stereotyping in Danish television advertisements. In the first study, 165 French television advertisements were analyzed by following established coding categories (A. Furnham & E. Skae, 1997; L. Z. McArthur & B. G. Resko, 1975). Contrary to prediction, the results showed that traditional gender role portrayal on French television was no different from that found in other countries. Separate statistical analyses were carried out for visually versus aurally classified central figures, yet this yielded relatively few significant differences. In the second study, a sample of 151 Danish advertisements was analyzed; results showed that Danish television was generally less gender stereotypic than French television in its portrayal of women. Exactly half (5) of the coding categories showed significant differences. Finally, an international statistical comparison between these two studies and similar research in Australia, Britain, and Italy was carried out. The methodological implications of these results are discussed as well as the theoretical issues arising from other studies of this sort.
The authors analyze some of the assumptions underlying most current research on television. They emphasize the dependence on (1) an individual rather than an institutional level of analysis; (2) a model of research utilization that pays little explicit attention to where sources of leverage lie for changes in programming; (3) extremely simple models of the selection processes associated with different levels of television viewing; and (4) uncritical appraisals of the consequences of effects that many would call small or modest. These issues are illustrated by a general discussion of the NIMH report on Television and Behavior and specific discussion of "mainstreaming" and the effects of television violence. In 1972, POQ's editors invited Leo Bogart to prepare an extended review article of the Surgeon-General's Study of Television and Social Behavior (POQ 36:491-521). When the 10-year follow-up study was released by NIMH in 1982, the editors asked Thomas D. Cook, a distinguished psychologist noted for his research on television, to perform the same function.
BACKGROUND: People who watch a lot of medical fiction overestimate the success rate of cardiopulmonary resuscitation (CPR). It has been suggested that this is because CPR is usually shown to be successful on television. This study analysed a popular Flemish medical drama series. Previous research showed that heavy viewing of this series was related to overestimation of CPR success. METHOD: Content analysis of 70 episodes of "Spoed" in the period between 2001 and the first three months of 2003. Causes and treatment of cardiac arrest and outcome of CPR were recorded in the same way as previous studies. RESULTS: CPR was performed 31 times in the 70 episodes. Only 19% of the patients survived the resuscitation attempt. Most patients were middle aged or older. Causes of arrest were different from those in British or American television series. CONCLUSIONS: The low survival rate challenges the idea that heavy viewers adopt the overestimation shown by television. Psychological research shows that people ignore base rate information in the shape of statistics, in favour of vivid, dramatic examples. Showing some impressive examples of success might therefore be more important than the overall success rate. It is suggested that the message of television fiction is that doctors are not powerless and that treatment does not stop once the heart stops beating. This helps to create what has been called an "illusion of efficacy".
The association of television viewing and obesity in data collected during cycles II and III of the National Health Examination Survey was examined. Cycle II examined 6,965 children aged 6 to 11 years and cycle III examined 6,671 children aged 12 to 17 years. Included in the cycle III sample were 2,153 subjects previously studied during cycle II. These surveys, therefore, provided two cross-sectional samples and one prospective sample. In all three samples, significant associations of the time spent watching television and the prevalence of obesity were observed. In 12- to 17-year-old adolescents, the prevalence of obesity increased by 2% for each additional hour of television viewed. The associations persisted when controlled for prior obesity, region, season, population density, race, socioeconomic class, and a variety of other family variables. The consistency, temporal sequence, strength, and specificity of the associations suggest that television viewing may cause obesity in at least some children and adolescents. The potential effects of obesity on activity and the consumption of calorically dense foods are consistent with this hypothesis.
OBJECTIVE: Elevated television (TV) viewing and physical inactivity promote obesity in children. Thus, changes in physical activity and sedentary behavior seem critical to treating childhood obesity. PRESENT STUDY: Using a randomized, 2-arm design, this pilot study tested the effects of contingent TV on physical activity and TV viewing in 10 obese children. TV viewing was contingent on pedaling a stationary cycle ergometer for experimental participants but was not contingent on pedaling for control participants. The study was conducted over 12 weeks, including a 2-week baseline period. RESULTS: Multivariate analyses indicated that the intervention significantly increased pedaling and reduced TV-viewing time. During the treatment phase, the experimental group pedaled 64.4 minutes per week on average, compared with 8.3 minutes by controls. The experimental group watched 1.6 hours of TV per week on average, compared with 21.0 hours per week on average by controls during this phase. Secondary analyses indicated that the experimental group showed significantly greater reductions in total body fat and percent leg fat. Total pedaling time during intervention correlated with greater reductions in percent body fat (r = -0.68). CONCLUSIONS: Contingencies in the home environment can be arranged to modify physical activity and TV viewing and may have a role in treating childhood obesity. Contingent TV may be one method to help achieve this goal.
CONTEXT: Television (TV) viewing is associated with obesity among school-aged children, adolescents, and adults, but this relationship has not been evaluated in preschool-aged children. OBJECTIVE: To describe the TV/video viewing habits of a multiethnic, low-income preschool population of children and to determine whether TV/video viewing is related to their adiposity. DESIGN: Cross-sectional survey of parents/guardians with measurements of children's height and weight. SETTING AND PARTICIPANTS: Two thousand seven hundred sixty-one adults with children, 1 through <5 years, from 49 New York State agencies of the Supplemental Nutrition Program for Women, Infants, and Children. OUTCOME MEASURES: Cross-sectional relationships between the amount of time the child spends viewing TV/video and the presence of a TV set in the child's bedroom, with the prevalence of overweight children (body mass index [BMI] >85th percentile) after adjustment for potential confounders. RESULTS: Mean TV/video viewing times were higher among black children and Hispanic children than white children and increased with the child's age. In multiple logistic regression, the odds ratio of children having a BMI >85th percentile was 1.06 (95% confidence interval [CI]: 1.004-1.11) for each additional hour per day of TV/video viewed, independent of child age, child sex, parental educational attainment, and race/ethnicity. Almost 40% of children had a TV set in their bedroom; they were more likely to be overweight and spent more time (4.6 hours per week) watching TV/video than children without a TV in their bedroom. In multiple logistic regression, the odds ratio of having a BMI >85th percentile was 1.31 (95% CI: 1.01-1.69) among those with a TV in their bedroom versus those without a TV, after statistical adjustment for child age, child sex, child TV/video viewing hours per week, maternal BMI, maternal education, and race/ethnicity. CONCLUSIONS: This study extends the association between TV viewing and risk of being overweight to younger, preschool-aged children. A TV in the child's bedroom is an even stronger marker of increased risk of being overweight. Because most children watch TV by age 2, educational efforts about limiting child TV/video viewing and keeping the TV out of the child's bedroom need to begin before then.
