The association of television and video viewing with fast food intake by preschool-age children.

OBJECTIVE: To examine the extent to which television (TV) and video viewing is associated with consumption of fast food by preschool-age children. RESEARCH METHODS AND PROCEDURES: In a cross-sectional study of 240 parents of children ages 2.0 to 5.9 years, parents reported the number of hours their child watched TV/videos on an average weekday and weekend day in the past month; a daily, weighted average of TV/video viewing was then calculated. The main outcome was parents' report of their children's fast food intake, using the question, "How many times a week does your child eat at fast food restaurants such as McDonald's, Burger King, or Kentucky Fried Chicken?" dichotomized to (never/<1 vs. > or =1 time/wk). The association of TV/video viewing with fast food intake was evaluated by multiple logistic regression before and after adjusting for several potential confounders. RESULTS: Twenty-two percent of parents reported that their child ate at fast food restaurants at least once per week. After adjusting for parents' age, race/ethnicity, and household income as well as child's age and sex, for each 1-hour increase of TV/video watched per day, the odds ratio (OR) for consuming fast food > or =1 time per week was 1.60 (95% confidence interval, 1.03 to 2.49). After further adjustment for socio-environmental factors that might serve as proxies for the availability of healthy food options, such as parental time constraints and the availability and high cost of fresh fruits and vegetables in their neighborhoods, the OR for consuming fast food > or =1 time per week was minimally attenuated (OR, 1.55; 95% confidence interval, 1.04 to 2.31). DISCUSSION: TV/video viewing was correlated with fast food consumption among preschool children in this study. Our findings raise the possibility that greater exposure to TV and videos may influence preschool children's consumption of unhealthful foods.

The role of closed circuit television in the teaching of operative dentistry.

Closed circuit television has been used in the Department of Operative Dental Surgery of the University of Newcastle-upon-Tyne since 1966. The medium has played an increasingly important role in the teaching of technique courses, especially after 1978 when the large 80-place teaching laboratory of the newly-built Dental School was commissioned.

Positive responses to televised beer advertisements associated with drinking and problems reported by 18 to 29-year-olds.

AIMS: To examine the nature of the relationships between responses to alcohol advertisements and drinking behaviour and related problems. To examine the role of positive and negative beliefs about drinking as intervening variables. DESIGN: Survey utilizing a CATI (computer-assisted telephone interviewing) system, involving interviews with 1012 randomly selected respondents. SETTING: Respondents were randomly selected from throughout New Zealand. PARTICIPANTS: Eighteen to twenty-nine-year-old New Zealanders. MEASUREMENTS: Response to specific alcohol advertisements was measured by recalled exposure (how often they recalled having seen the advertisements) and liking (a measure of positive response). FINDINGS: An exploratory non-recursive structural equation model, based on 791 drinkers provided tentative support for the hypothesis that positive responses to televised beer advertisements (as measured by liking) contributed to the quantity of alcohol consumed on drinking occasions, which in turn contributed to the level of alcohol-related problems. The model, which provided a good fit to the data, was consistent with the hypothesis that liking of beer advertisements had both a direct influence on quantities of alcohol consumed and an indirect influence, via its influence on positive beliefs. These effects were present after controlling for reciprocal effects, none of which were significant. The data did not support the hypothesis that the quantities of alcohol consumed would influence the respondent's liking of beer advertisements. Recalled exposure was not a significant influence on the quantities consumed. CONCLUSIONS: The results are consistent with a number of theoretical perspectives and with a growing body of research that are suggestive of alcohol advertising having some influence on the consumption of younger people.

Physical signs associated with excessive television-game playing and sleep deprivation.

BACKGROUND: To elucidate significance of physical signs seen in excessive television-game (TVG) players complaining of unexplained persistent symptoms, a cross-sectional cohort study was designed. METHODS: A total of 1143 school children, aged between 6 and 11-years-old, and their parents were included in the study. Questionnaires were sent to guardians asking the number of hours that their children watched TV, TVG, and slept. All children were examined to check for three physical signs, black rings in the skin under the eye (BR), muscle stiffness in the shoulder (MS), and displacement of the scapula associated with muscle stiffness in the shoulder (DS/MS) by inspection and palpitation. RESULTS: The three signs, BR, MS and DS/MS, were present in 165 (14.4%), 229 (20.0%) and 72 (6.2%) children, respectively. Boys had greater frequencies of two signs than girls (BR, 19.6% vs 8.9%, P<0.01; MS, 26.1% vs 13.6%, P<0.01), respectively. Boys spent more time on TVG playing than girls (1.1+/-0.7 h/day vs 0.4+/-0.6 h/day, P<0.0001), respectively. Excessive TVG players, who spent > or = 1 h/day for TVG had greater frequencies of two signs, BR and MS, than those of non-TVG-players (18.9% vs 13.0%, P<0.05; 25.6% vs 14.4%, P<0.01), respectively. The TVG playing time correlated with two signs, BR (P=0.0143) and MS (P=0.0048). Furthermore, sleep deprivation related to three signs, BR (P=0.0078), MS (P<0.0001) and DS/MS (P=0.0290). CONCLUSIONS: Excessive TVG playing links to the occurrence of BR and MS. Other factors, which cause sleep deprivation, may underlie in the occurrence of the three signs. The amount of time spent on TVG playing should be regulated to < 1.0 h/day.

[A pair of spectacles to improve the information from the x-ray photograph and from the radioscopy on the television screen (author's transl)].

Here a pair of spectacles is introduced which, in screening the lateral incidence of light and in variably cross fading the risual point eliminates the contrast-diminishing intraocular proceeding stray light. It helps to achieve an improvement of the contrast by considering the x-ray photograph or television image. The result is that details are easier perceptible.

Violence, television and the health of American youth.

In 1973, 18,032 young Americans, 15 to 24 years of age, died in motor-vehicle accidents, 5182 were murdered, and 4098 committed suicide. The death rate, for this age group, was 19 per cent higher in 1973-74 than it had been in 1960-61, owing entirely to deaths by violence. The largest rise in deaths from homicide during the past two decades was at the ages of one to four. For a considerable proportion of American children and youth, the "culture of violence" is now both a major health threat and a way of life. One contributing factor is television's massive daily diet of symbolic crime and violence in "entertainment" programs. After numerous studies of televsion influence on real-life violence, including two major government commissions, the industry is experimenting with a 7 to 9 p.m. "Family Hour" (6 to 8 p.m. Central Time) from which violence, along with sex, has been largely banished. Three industry unions claim censorship and are suing. The medical profession is urged to concern itself with this serious and complex health hazard.

The impact of suicide in television movies. Evidence of imitation.

Increasing evidence suggest that imitative behavior may have a role in suicide among teenagers. We studied the variation in the numbers of suicides and attempted suicides by teenagers in the greater New York area two weeks before and two weeks after four fictional films were broadcast on television in the fall and winter of 1984-1985. The mean number of attempts in the two-week periods after the broadcasts (22) was significantly greater than the mean number of attempts before the broadcasts (14; P less than 0.05), and a significant excess in completed suicides, when compared with the number predicted, was found after three of the broadcasts (P less than 0.05). We conclude that the results are consistent with the hypothesis that some teenage suicides are imitative and that alternative explanations for the findings, such as increased referrals to hospitals or increased sensitivity to adolescent suicidal behavior on the part of medical examiners or hospital personnel, are unlikely to account for the increase in attempted and completed suicides.

Television viewing behaviour and associations with food habits in different countries.

OBJECTIVE: Several environmental factors influence adolescents' food habits and television (TV) viewing is thought to be one of these factors. The purpose of the present study was to describe sociodemographic differences in TV viewing and to examine associations of TV viewing with the consumption of sweets, soft drinks, fruit and vegetables in different countries. METHODS: Data were collected from 162,305 young people completing the 2001/02 Health Behaviour in School-Aged Children survey, a World Health Organization cross-national study on health and health behaviours among 11-, 13- and 15-year-old school pupils. Analyses of variance were used to examine sociodemographic differences in TV viewing and logistic regression analyses to examine associations between TV viewing and food habits. RESULTS: Large differences were found between countries in reported daily TV viewing time, from an average of 2.0 h in Switzerland to 3.7 h in Ukraine. The results indicate that those most likely to watch TV are boys, 13-year-olds and pupils of lower socio-economic status. Those who watched more TV were more likely to consume sweets and soft drinks on a daily basis and less likely to consume fruit and vegetables daily, although the latter associations were not so apparent among Central and Eastern European countries. CONCLUSIONS: Given the high TV viewing rates among adolescents and the association with less healthy food options, many young people are at increased risk of overweight or obesity. Interventions to modify TV viewing behaviour are needed. The findings underscore the importance of tackling socio-economic differences.

Television advertising and children: lessons from policy development.

AIM: To conduct a policy review of the regulations related to food advertising on television aimed at children. DESIGN: The study consisted of documentary analysis of relevant legislation and policy documents related to children's advertising from both industry and non-governmental organisations at a global level and in 20 countries. This was supported with semi-structured telephone interviews with individuals from 11 countries. RESULTS: The initial findings resulted in a listing of regulatory impacts from which we developed a taxonomy of regulatory schemes. There was a tension between the development of legislation to cover this area and the use of voluntary agreements and codes. This tension represents a food industry/civic society split. The food and advertising industries are still engaged in a process of denying the impact of advertising on food choice and children as well as commissioning their own research. Outright bans are unusual, with most countries addressing the situation through voluntary agreements and self-regulation. We found a deep division over the way forward and the role and place of legislation. Policy-makers expressed concerns that national legislation was increasingly less relevant in dealing with broadcast media transmitted from outside national boundaries and therefore not subject to the receiving countries' laws but to the laws of the country from which they were transmitted. CONCLUSIONS: The options for the regulation of advertising targeted at children range from (1) a complete ban on advertising as in the case of Sweden, through (2) partial restrictions on advertising by type of food, target group or limits on the amount of advertisements or times shown, to (3) continuation of self-regulation by the advertising and food industries. There is a global dimension to regulation that needs to be built in, as national frontiers are no barriers to broadcast media and public health nutrition needs to ensure that its concerns are heard and addressed.

Associations between television viewing and consumption of commonly advertised foods among New Zealand children and young adolescents.

OBJECTIVES: To explore how time spent watching television (TV) is associated with the dietary behaviours of New Zealand children and young adolescents. DESIGN: Secondary data analysis of a nationally representative, cross-sectional survey. SETTING: In homes or schools of New Zealand school students. PARTICIPANTS: In total, 3275 children aged 5 to 14 years. RESULTS: The odds of being overweight or obese increased with duration of TV viewing for children and adolescents when controlling for age, sex, ethnicity, socio-economic status and physical activity. Children and adolescents who watched the most TV were significantly more likely to be higher consumers of foods most commonly advertised on TV: soft drinks and fruit drinks, some sweets and snacks, and some fast foods. Both children and adolescents watching two or more hours of TV a day were more than twice as likely to drink soft drinks five times a week or more (P = 0.03 and P = 0.04, respectively), eat hamburgers at least once a week (both P = 0.02), and eat French fries at least once a week (both P < 0.01). CONCLUSIONS: These findings suggest that longer duration of TV watching (thus, more frequent exposure to advertising) influences the frequency of consumption of soft drinks, some sweets and snacks, and some fast foods among children and young adolescents. Efforts to curtail the amount of time children spend watching TV may result in better dietary habits and weight control for children and adolescents. Future studies examining the impact of advertising on children's diets through interventions and international comparisons of legislation would provide more definitive evidence of the role of advertising in child and adolescent obesity.

Electrodermal responses to implied versus actual violence on television.

The electrodermal response (EDR) of children watching a violent show was measured. Particular attention was paid to the type of violence (actual or implied) that prompted an EDR. In addition, the impact of the auditory component (sounds associated with violence) of the show was evaluated. Implied violent stimuli, such as the villain's face, elicited the strongest EDR. The elements that elicited the weakest responses were the actual violent stimuli, such as stabbing. The background noise and voices of the sound track enhanced the total number of EDRs. The results suggest that implied violence may elicit more fear (as measured by EDRs) than actual violence does and that sounds alone contribute significantly to the emotional response to television violence. One should not, therefore, categorically assume that a show with mostly actual violence evokes less fear than one with mostly implied violence.

Impact of television news exposure on children's perceptions of violence in Northern Ireland.

The present study assessed the impact of television news exposure on Irish children's perceptions of the level of violence in their neighborhoods. Estimates from children (N = 570) of the local levels of violence in three areas (high-, low-, and no-violence) were subjected to a four-way analysis of variance (Area x Sex x Age x News Exposure) that showed a main effect for area and sex with respect to the high-violence area and boys. Two two-way interactions also reached statistical significance. The first suggested that the perception of lower levels of violence by girls was confined to the high- and low-violence areas. The second concerned the level of actual violence and the amount of reported news exposure. Only in the high-violence area were these two variables related: Accurate estimates of actual violence levels were associated with more frequent news exposure.

Prosocial effects of entertainment television in India.

The study examines the prosocial effects of Hum Log (We People), India's 1st long running television soap opera. Hum Log was a prosocial TV program that was designed to promote women's status in Indian society. Regression analysis was used to measure the degree to which exposure to Hum Log affected viewers' (1) awareness of certain prosocial beliefs promoted by the series, (2) level of TV dependency, (3) involvement with the characters of Hum Log, and (4) adherence to 3 prosocial beliefs promoted by Hum Log. Exposure to Hum Log was positively associated with viewer's awareness of the program's prosocial messages, TV dependency, and involvement with TV characters in the series. Viewers who were more exposed to Hum Log were also more likely to believe in women's equality and women's freedom of choice, but not in family planning. The implications of these findings are discussed in terms of present and future research on the use of prosocial TV programs for development in Asia.

Introduction of high definition television system to neurosurgical documentation.

The high definition television (HDTV) system is introduced to microneurosurgery. Five cases with intracranial lesions: three cerebral aneurysms (giant aneurysms of the anterior communicating artery and internal carotid artery, aneurysm of the basilar artery), one acoustic neurinoma and one skull base meningioma, were operated on under the microscope using the HDTV system. The surgical procedures of each case were relayed and recorded by the system. In two of the five cases, we used two sets of HDTV system to produce stereoscopic projection. The HDTV system provided us with images of superior quality with a distinctly greater resolution than ordinary video systems.

Two-way television: an experiment in interactive programming for the elderly.

This study was conducted to 1) assess the effectiveness of an experimental two-way cable TV system in reaching the older people for whom it was designed, and 2) assess the attraction of this locally-based age-targeted system for its viewers. The study evaluates the system's effectiveness in reaching its target audience by examining information about the types of viewers--both younger and older--who have been attracted to the system. In addition, differences in factors that predict viewing frequency for younger and older people are used to illuminate life stage differences in people's attraction to locally-based TV programming. Findings show that the system had successfully reached its target audience within two years of inception. Watching the interactive TV programs because of the system's provision of information about local events and because of the senior citizens' focus strongly predicted viewing frequency for both older and younger respondents. The ability of locally-based interactive TV programming to serve social and informational needs of older people which are unmet by traditional broadcast television is discussed.

Can a television series change attitudes about death? A study of college students and Six Feet Under.

This study examined the effects of viewing 10 episodes of the television series Six Feet Under to assess whether such programming could influence college students' attitudes about death and dying. Students were administered the Death Attitude Profile--Revised, the Multidimensional Fear of Death Scale, and the short version of the Threat Index, prior to and after viewing. Significant changes were found on a number of measures. These results are similar to the effects of didactic death education courses.
