The effects of television form and violent content on boys' attention and social behavior.

An experiment is reported that examined the independent effects of television content (violence) and television formal features (action level) on children's attention to programs and their postviewing social behavior. Pairs of preschool boys participated in two experimental sessions in which they saw animated and live television programs that varied in violent content (high or low) and formal features (high or low action level). They then played with toys that contained cues for either aggressive or prosocial interaction. Rapid character action facilitated visual attention to the programs; violent tv content did not facilitate attention. On measures of social behavior, strong effects of toy cues were found independently of television treatment effects. Aggressive toys produced aggressive behavior, and prosocial toys produced prosocial behavior; these patterns included some nonspecific, generalized influences in addition to direct demands of the play materials. Violent tv content led to changes in subjects' style of interaction and was also associated with increases in some prosocial behaviors. Television action level had no systematic effects on subjects' behavior. Results are discussed within the theoretical frameworks of observational learning and general arousal. Implications for children's television programming are also discussed.

Television and teens: health implications. Executive summary.

Throughout the study group deliberations, there were issues that cross-cut all discussions and suggestions. While the focus of the conference was on television, it is not possible to talk about television without including advertising, cable, and independent stations as well as the networks. In addition, television cannot be discussed in isolation from movies, for with VCRs and television reruns, movies are an integral part of the television scene. A second theme that transcended most discussion was a reluctance to call upon external regulatory mechanisms to control what many see as the excesses of television. There was sensitivity and concern for striking a balance between safeguarding basic freedoms, on one hand, and assuring the health and well being of the nation on the other. In terms of specific recommendations, there were some key general agreements: 1. Need for Interdisciplinary Dialog. Repeatedly, concern was voiced on how little understanding there is among and between those who are primarily concerned with the health and development of young people and those who develop programs viewed by that population.(ABSTRACT TRUNCATED AT 250 WORDS)

Alcohol use in television programming: effects on children's behavior.

The impact of televised use of alcoholic beverages on children's behavior was evaluated in this study. Children were randomly assigned to one of three experimental conditions: (a) television with drinking depicted, (b) television without drinking, or (c) a no television control condition. Segments of the syndicated television show M.A.S.H. were used as the viewing stimulus. The impact of the various conditions was evaluated in a choice task requiring subjects to choose either martini or regular glasses of either "whiskey" or "water" to serve pictured adults and children. Results indicated that subjects who viewed television drinking were significantly more likely to choose alcoholic beverages for pictured adults but not children. No effect was found for glass preference. Results and implications of these findings and directions for future research are discussed.

Faculty perceptions of teaching on television: one school's experience.

Videoteleconferencing (or teaching on television) represents a means of growing importance for distant learners to gain greater access to nursing education. Research has identified a number of key issues for nurse educators to consider related to videoteleconferencing: teaching/evaluation strategies, faculty workload, rewards and incentives, and support structures. The authors conducted an evaluation survey using a case study approach aimed at describing the perceptions of a convenience sample of faculty members (n = 17) regarding their recent television experiences. The survey, conducted by means of a mailed questionnaire, examined perceptions centering on sources of support, reception site logistics, rewards teaching strategies, and future directions. Key findings included: overall, respondents perceived television teaching positively; reception site, administrative support, and peer support were important to faculty; additional preparation time was required for television teaching; teaching on television required changes in style and pedagogical strategies; and student-teacher interactions were affected by the medium. Findings have implications for the implementation of videoteleconferencing operations, recruitment of faculty for television teaching, and evaluation of videoteleconferencing operations.

Television viewing and forms of bullying among adolescents from eight countries.

PURPOSE: Based on theories suggesting that frequent television viewers act and react in hostile, malicious, malevolent, or verbally aggressive ways rather than being physically violent, the present study investigates relationships between television viewing and different forms of bullying. METHODS: Multilevel regression models were estimated based on cross-sectional data from 31,177 adolescents aged 11, 13, and 15 years from Canada, Estonia, Israel, Latvia, Macedonia, Poland, Portugal, and the United States who participated in the 2001-2002 Health Behavior in School-aged Children Survey. RESULTS: Although all different forms of bullying were associated with television viewing in bivariate analyses, only the verbal forms (i.e. "calling mean names" and "spreading rumors") remained significant in multiple regression models. These relationships were observed consistently in all eight participating countries. However, the association between television viewing and physical forms of bullying such as kicking, pushing, or shoving around, varied across countries. In most weekend TV viewing cultures, frequent television viewers were prone to kick or push another student in addition to verbal forms of bullying, which was not the case in weekday viewing cultures. CONCLUSIONS: These results demonstrate the importance of limiting adolescents' time engaged in unsupervised television watching, and the need to motivate adolescents to engage in joint family activities or organized after-school activities.

Television viewing and smoking volume in adolescent smokers: a cross-sectional study.

BACKGROUND: Previous research has shown a relationship between television viewing and smoking initiation. The relationship between television viewing and the amount of cigarettes consumed by adolescent smokers per time unit (day, week, month...) has not yet been studied. METHODS: A cross-sectional sample of children by means of self-reports administered by research assistants in schools was obtained. Participants were 421 smokers in a random sample of 4th year students in 15 secondary schools in Flanders, Belgium. Main outcome measures were quantifiable, closed survey questions about smoking volume, whether or not parents and friends smoked, frequency of going out and average weekly TV viewing volume. RESULTS: Television viewing was a significant predictor of smoking volume. Smokers who watch more TV smoke more. The relationship was curvilinear (quadratic). The relationship becomes stronger (curves upward) for higher levels of viewing. Those who watch 5 or more hours a day smoke between 60 and 147 cigarettes more per week than those who watch 1 h or less. CONCLUSIONS: Television viewing is significantly related to smoking volume. The content of television may glamorize smoking. Children may learn to associate smoking with viewing regardless of content. It is also possible that heavier smoking leads to more viewing or that a third variable influences both smoking volume and viewing. Regardless of the causal direction of the relationship television viewing appears to be an indicator or predictor of smoking volume. The curvilinear nature of the relationship deserves further attention.

Television viewing and low participation in vigorous recreation are independently associated with obesity and markers of cardiovascular disease risk: EPIC-Norfolk population-based study.

OBJECTIVE: This study describes the associations between sedentary behaviour (television viewing) and participation in vigorous recreational activity with obesity and with biomarkers of cardiovascular disease (CVD) risk profile. DESIGN: Cross-sectional analysis of the EPIC-Norfolk cohort study. SETTING: The study is a population-based study of participants living in Norfolk, UK. SUBJECTS: A total of 15 515 men and women aged between 45 and 74 y, recruited through General Practice lists, who completed the detailed physical activity questionnaire. RESULTS: Following exclusion of those with self-reported myocardial infarction, stroke and diabetes, 14 189 participants remained for the analysis. Self-reported television viewing was positively and participation in vigorous activity negatively associated with markers of obesity, blood pressure and plasma lipids. In multiple regression analysis, adjusting for age, alcohol, smoking, treatment for hypertension, vigorous and total physical activity, these associations remained significant. For women who participated in more than 1 h/week of vigorous activity and who watched fewer than 2 h of television each day, the adjusted mean body mass index was 1.92 kg/m(2) less than for women who reported participating in no vigorous activity and who watched more than 4 h of television each day (P<0.001). The equivalent figure for men was 1.44 kg/m(2) (P<0.001). In a similar analysis, with blood pressure as the outcome, mean diastolic blood pressure difference between the extreme groups of vigorous activity and television viewing was 3.6 mmHg in men (P<0.001) and 2.7 mmHg (P=0.001) in women. CONCLUSIONS: These data suggest that time spent participating in vigorous recreational physical activity and television viewing, an indicator of a sedentary lifestyle, are associated with obesity and markers of CVD disease risk independent of total reported physical activity. Whether these observations represent the true underlying aetiological relations or are a manifestation of the different precision with which the subdimensions of activity are measured remains uncertain.

Association of obesity with physical activity, television programs and other forms of video viewing among children in Mexico city.

OBJECTIVE: To assess the association of physical activity, television program viewing and other forms of video viewing with the prevalence of obesity among school children. DESIGN: Cross-sectional study. SUBJECTS: 712 children, 9-16 y old, from a low- and a middle-income town in the Mexico City area. MEASUREMENTS: Children completed a self administered questionnaire to assess time spent in physical activity and television viewing, and diet. Height weight and triceps skinfolds were measured. The outcome variable was obesity, and the covariates were hours of television programs and other video viewing, physical activity, energy intake, percentage of energy from fat, town of location of school, age, gender and perception of mother's weight status. RESULTS: Among 461 children with complete information, 24% were classified as obese. Children reported an average of 4.1 +/- 2.2 h/d watching television (2.4 +/- 1.5 h/d for TV programs and 1.7 +/- 1.5 h/d for video cassette recorder (VCR) or videogames), and 1.8 +/- 1.3 h/d in moderate and vigorous physical activities. Odds ratios (OR) of obesity were 12% higher for each hour of television program viewing per day (OR = 1.12, 95% confidence interval (CI) 1.02,-1.22), and 10% lower for each hour of moderate/vigorous physical activity per day (OR = 0.90, 95% CI 0.83-0.98), controlling for age, gender, town and perception of mother's weight status. Children in the middle-income town had higher adjusted odds of obesity (OR = 2.58, 95% CI 1.47-4.54). CONCLUSION: Physical activity and television viewing, but not VCR/videogames use, were related to obesity prevalence in Mexican children 9-16 y old.

Watching television is associated with childhood obesity: but is it clinically important?

OBJECTIVE: To assess the impact of television viewing during childhood and adolescence on body mass index (BMI) in children up to the age of 15 years. DESIGN: Unselected birth cohort, assessed at birth and every 2 years from age 3 to 15 years. SUBJECTS: In all, 1037 individuals were assessed at age 3 years. At age 15 years, 976 (95% of living cohort) continued to participate. MEASUREMENTS: Parental estimates of weekday television viewing between age 5 and 11 years. Self-reports of television viewing at age 13 and 15 years. Weight and height were measured at each age to calculate BMI. RESULTS: BMI and prevalence of overweight at all ages were significantly associated with mean hours of television viewing reported in the assessments up to that age. These associations were stronger in girls than boys. The associations remained significant after adjusting for parental body mass indices and socio-economic status. CONCLUSION: Time spent watching television is a significant predictor of BMI and overweight in childhood. Although the effect size appears small, it is larger than the effect sizes commonly reported for nutritional intake and physical activity. Television viewing should be regarded as an important contributing factor to childhood obesity.

Television, computer use and body mass index in Australian primary school children.

OBJECTIVE: To investigate relationships between children's body mass index (BMI) and parent reports of children's television and video game/computer habits, controlling for other potential risk factors for paediatric obesity. METHODS: Child BMI was calculated from measured height and weight collected in 1997 as part of a large, representative, cross-sectional study of children in Victoria, Australia. Parents reported the amount of time children watched television and used video games/computers, children's eating and activity habits, parental BMI and sociodemographic details. RESULTS: A total of 2862 children aged 5-13 years participated. Child mean BMI z-score was significantly related to television (F = 10.23, P < 0.001) but not video game/computer time (F = 2.23, P = 0.09), but accounted for only 1 and 0.2% of total BMI variance, respectively. When parental BMI, parental education, number of siblings, food intake, organized exercise and general activity level were included, television ceased to be independently significantly related to child BMI. Using adjusted logistic regression, the odds of being overweight and obese generally increased with increasing television viewing. No relationship was found for video game/computer use. CONCLUSIONS: A small proportion of variance in child BMI was related to television, but not video game/computer time. This was far outweighed by the influence of other variables. Causal pathways are likely to be complex and interrelated.

Comparison of television and telephone for remote medical consultation.

Television and telephone communications were randomly used to compare their effectiveness in allowing consultation between a hospital-based physician and remote nurse practitioners. Visits using television for consultation averaged 50 minutes as compared with 40 minutes for telephone. This difference was caused by longer work-ups before the consultation, longer delays after it was requested, and longer consultations, themselves, on television. However, television consultations resulted in significantly fewer immediate referrals of patients to hospital physicians: 6 plus or minus 1 as compared to 12 plus or minus 1 per cent (mean plus or minus S.E.M) OF ALL TELEPHONE CONSULTATIONS (P SMALLER THAN 0.005). Although no overall difference in satisfaction was documented between the results of television and telephone consultations, participants preferred the former for medical decision making and cited it for allowing more social interaction than telephone. These findings suggest that television may have its greatest value in remote sites where the sense of isolation is great and the need to reduce long-distance referrals offsets the costs of the system.

Cardiopulmonary resuscitation on television. Miracles and misinformation.

BACKGROUND: Responsible, shared decision making on the part of physicians and patients about the potential use of cardiopulmonary resuscitation (CPR) requires patients who are educated about the procedure's risks and benefits. Television is an important source of information about CPR for patients. We analyzed how three popular television programs depict CPR. METHODS: We watched all the episodes of the television programs ER and Chicago Hope during the 1994-1995 viewing season and 50 consecutive episodes of Rescue 911 broadcast over a three-month period in 1995. We identified all occurrences of CPR in each episode and recorded the causes of cardiac arrest, the identifiable demographic characteristics of the patients, the underlying illnesses, and the outcomes. RESULTS: There were 60 occurrences of CPR in the 97 television episodes--31 on ER, 11 on Chicago Hope, and 18 on Rescue 911. In the majority of cases, cardiac arrest was caused by trauma; only 28 percent were due to primary cardiac causes. Sixty-five percent of the cardiac arrests occurred in children, teenagers, or young adults. Seventy-five percent of the patients survived the immediate arrest, and 67 percent appeared to have survived to hospital discharge. CONCLUSIONS: The survival rates in our study are significantly higher than the most optimistic survival rates in the medical literature, and the portrayal of CPR on television may lead the viewing public to have an unrealistic impression of CPR and its chances for success. Physicians discussing the use of CPR with patients and families should be aware of the images of CPR depicted on television and the misperceptions these images may foster.

Television and delivery of health promotion programs to remote Aboriginal communities.

ISSUE ADDRESSED: To assess the effect of anti-tobacco television advertising in comparison to other anti-tobacco interventions for Aboriginal people in remote communities in the Northern Territory. METHOD: This research was carried out as part of a large study evaluating the effect of multi-component, evidence-based tobacco interventions developed in three remote communities. Community surveys (assessing changes in smoking behaviour and exposure to tobacco interventions) were used to assess exposure to and effect of television advertising, relative to other interventions over the intervention year. RESULTS: 351 community members were interviewed. Exposure to anti-tobacco television advertising was high among both smokers and non-smokers (86% vs. 85%, p = 0.78). However, those who recalled seeing anti-tobacco advertising were no more likely to have quit than those who had not (11 exposed (6%) vs. 3 non-exposed (10%), Fisher's Exact Test p = 0.42). Logistic regression showed that exposure to individual tobacco interventions was not associated with an increased chance of cessation during the intervention year. CONCLUSION: Recall of anti-tobacco television advertising was high in these remote Aboriginal communities; more Aboriginal people recalled exposure to anti-tobacco television advertising than to any other cessation intervention. Although the overall cessation rate was low, a small number of smokers had given up as a result of seeing these television advertisements.

The weighty issue of Australian television food advertising and childhood obesity.

ISSUE ADDRESSED: The aim of this paper is to provide an accessible overview of research literature on the link between childhood obesity and food advertising on Australian television. METHODS: A systematic review of current medical, public health, psychological and marketing research literature surrounding the topics of childhood obesity and television food advertising, with emphasis on Australian data. RESULTS: Childhood obesity rates have tripled since 1985, mirrored by increases in consumption of energy-dense foods. Energy-dense food advertising is ubiquitous in children's television programming, but children's ability to perceive the commercial intent of advertisements only emerges gradually as a function of age. Until such time, children are trusting, and hence vulnerable, to food advertising, influencing their desires and purchase requests to parents. There is robust evidence to suggest that television viewing and childhood obesity are related. However, the direction of causation and specific contribution of food advertising remains equivocal. Moreover, the link between television and childhood obesity is surprisingly weak, with only a small independent effect size (approximately 1%). CONCLUSIONS: Television food advertising seems to have only a very small, indirect link to childhood obesity.

Effects of visual and verbal sexual television content and perceived realism on attitudes and beliefs.

Previous studies of the effects of sexual television content have resulted in mixed findings. Based on the information processing model of media effects, I proposed that the messages embodied n such content, the degree to which viewers perceive television content as realistic, and whether sexual content is conveyed using visual or verbal symbols may influence the nature or degree of such effects. I explored this possibility through an experiment in which 182 college undergraduates were exposed to visual or verbal sexual television content, neutral television content, or no television at all prior to completing measures of sexual attitudes and beliefs. Although exposure to sexual content generally did not produce significant main effects, it did influence the attitudes of those who perceive television to be relatively realistic. Verbal sexual content was found to influence beliefs about women's sexual activity among the same group.

Direct-to-consumer drug advertisements on network television: an exploration of quantity, frequency, and placement.

Prescription and over-the-counter (OTC) drug advertisements that appear on television are among the most common forms of health communication reaching the U.S. public, but no studies to date have explored the quantity, frequency, or placement of these ads on television. We explored these questions by recording all programs and advertisements that appeared on network television in a southeastern city during a selected week in the summer of 2001 and coding each prescription and OTC drug ad for its frequency, length, and placement by time of day and television program genre. A total of 18,906 ads appeared in the 504-hour sample, including 907 OTC drug ads (4.8%) and 428 prescription (Rx) drug ads (2.3%), which together occupied about 8% of all commercial airtime. Although OTC drug ads were more common, Rx drug ads on average were significantly longer. Direct-to-consumer drug ads appeared most frequently during news programs and soap operas and during the middle-afternoon and early-evening hours. Overall, we found that direct-to-consumer drug advertisements occupy a large percentage of network television commercial advertising and, based on time and program placement, many ads may be targeted specifically at women and older viewers. Our findings suggest that Americans who watch average amounts of television may be exposed to more than 30 hours of direct-to-consumer drug advertisements each year, far surpassing their exposure to other forms of health communication.

Leisure-time physical activity, television watching, and plasma biomarkers of obesity and cardiovascular disease risk.

The benefits of physical activity in reducing cardiovascular disease (CVD) are thought to be mediated through changes in blood lipids, insulin sensitivity, and thrombogenic factors. Few studies have addressed the effects of both long-term physical activity and inactivity on these factors. The authors assessed associations between long-term leisure-time physical activity, television watching, and biomarkers of CVD risk among 468 healthy male health professionals. Prior to blood collection in 1993-1994, physical activity and television watching were assessed biennially from 1986 to 1994 by a questionnaire. Physical activity was expressed as metabolic equivalents-hours per week. Multivariate linear regression analyses showed that metabolic equivalents-hours in 1994 were significantly associated with high density lipoprotein cholesterol (HDL cholesterol) (positively) and with leptin and C-peptide (inversely). The average number of hours of television watching assessed in 1994 was significantly positively associated with low density lipoprotein cholesterol and significantly inversely associated with HDL cholesterol and apolipoprotein A1. Average hours of television watching per week assessed in 1988-1994 was positively associated with leptin levels (p < 0.01). The associations of television watching and vigorous activity with leptin and HDL cholesterol were independent of each other. In conclusion, physical activity and television watching were significantly associated with several biochemical markers of obesity and CVD risk.

Smoking scenes in popular Japanese serial television dramas: descriptive analysis during the same 3-month period in two consecutive years.

Japanese serial television dramas are becoming very popular overseas, particularly in other Asian countries. Exposure to smoking scenes in movies and television dramas has been known to trigger initiation of habitual smoking in young people. Smoking scenes in Japanese dramas may affect the smoking behavior of many young Asians. We examined smoking scenes and smoking-related items in serial television dramas targeting young audiences in Japan during the same season in two consecutive years. Fourteen television dramas targeting the young audience broadcast between July and September in 2001 and 2002 were analyzed. A total of 136 h 42 min of television programs were divided into unit scenes of 3 min (a total of 2734 unit scenes). All the unit scenes were reviewed for smoking scenes and smoking-related items. Of the 2734 3-min unit scenes, 205 (7.5%) were actual smoking scenes and 387 (14.2%) depicted smoking environments with the presence of smoking-related items, such as ash trays. In 185 unit scenes (90.2% of total smoking scenes), actors were shown smoking. Actresses were less frequently shown smoking (9.8% of total smoking scenes). Smoking characters in dramas were in the 20-49 age group in 193 unit scenes (94.1% of total smoking scenes). In 96 unit scenes (46.8% of total smoking scenes), at least one non-smoker was present in the smoking scenes. The smoking locations were mainly indoors, including offices, restaurants and homes (122 unit scenes, 59.6%). The most common smoking-related items shown were ash trays (in 45.5% of smoking-item-related scenes) and cigarettes (in 30.2% of smoking-item-related scenes). Only 3 unit scenes (0.1 % of all scenes) promoted smoking prohibition. This was a descriptive study to examine the nature of smoking scenes observed in Japanese television dramas from a public health perspective.
