Incidence of Childhood and Adolescent Melanoma in the United States: 1973–2009
Incidence of Childhood and Adolescent Melanoma in the United States: 1973–2009
Source: Pediatrics
OBJECTIVE:
Childhood and adolescent melanoma is rare but has been increasing. To gain insight into possible reasons underlying this observation, we analyzed trends in melanoma incidence diagnosed between the ages of 0 and 19 years among US whites by gender, stage, age at diagnosis, and primary site. We also investigated incidence trends by UV-B exposure levels.
METHODS:
By using Surveillance, Epidemiology, and End Results (SEER) program data (1973–2009), we calculated age-adjusted incidence rates (IRs), annual percent changes, and 95% confidence intervals for each category of interest. Incidence trends were also evaluated by using joinpoint and local regression models. SEER registries were categorized with respect to low or high UV-B radiation exposure.
RESULTS:
From 1973 through 2009, 1230 children of white race were diagnosed with malignant melanoma. Overall, pediatric melanoma increased by an average of 2% per year (95% confidence interval, 1.4%–2.7%). Girls, 15- to 19-year-olds, and individuals with low UV-B exposure had significantly higher IRs than boys, younger children, and those living in SEER registries categorized as high UV-B. Over the study period, boys experienced increased IRs for melanoma on the face and trunk, and females on the lower limbs and hip. The only decreased incidence trend we observed was among 15- to 19-year-olds in the high UV-B exposure group from 1985 through 2009. Local regression curves indicated similar patterns.
CONCLUSIONS:
These results may help elucidate possible risk factors for adolescent melanoma, but additional individual-level studies will be necessary to determine the reasons for increasing incidence trends.
Food-Related Parenting Practices and Adolescent Weight Status: A Population-Based Study
Food-Related Parenting Practices and Adolescent Weight Status: A Population-Based Study
Source: Pediatrics
OBJECTIVE: To examine food-related parenting practices (pressure-to-eat and food restriction) among mothers and fathers of adolescents and associations with adolescent weight status within a large population-based sample of racially/ethnically and socioeconomically diverse parent-adolescent pairs.
METHODS: Adolescents (N = 2231; 14.4 years old [SD = 2.0]) and their parents (N = 3431) participated in 2 coordinated population-based studies designed to examine factors associated with weight status and weight-related behaviors in adolescents. Adolescents completed anthropometric measurements and surveys at school. Parents (or other caregivers) completed questionnaires via mail or phone.
RESULTS: Findings suggest that the use of controlling food-related parenting practices, including pressure-to-eat and restriction, is common among parents of adolescents. Mean restriction levels were significantly higher among parents of overweight and obese adolescents compared with nonoverweight adolescents. However, levels of pressure-to-eat were significantly higher among nonoverweight adolescents. Results indicate that fathers are more likely than mothers to engage in pressure-to-eat behaviors and boys are more likely than girls to be on the receiving end of parental pressure-to-eat. Parental report of restriction did not differ significantly by parent or adolescent gender. No significant interactions by race/ethnicity or socioeconomic status were seen in the relationship between restriction or pressure-to-eat and adolescent weight status.
CONCLUSIONS: Given that there is accumulating evidence for the detrimental effects of controlling feeding practices on children’s ability to self-regulate energy intake, these findings suggest that parents should be educated and empowered through anticipatory guidance to encourage moderation rather than overconsumption and emphasize healthful food choices rather than restrictive eating patterns.

OBJECTIVES: Recorded music risks overstimulation in NICUs. The live elements of music such as rhythm, breath, and parent-preferred lullabies may affect physiologic function (eg, heart and respiratory rates, O2 saturation levels, and activity levels) and developmental function (eg, sleep, feeding behavior, and weight gain) in premature infants.
METHODS: A randomized clinical multisite trial of 272 premature infants aged ≥32 weeks with respiratory distress syndrome, clinical sepsis, and/or SGA (small for gestational age) served as their own controls in 11 NICUs. Infants received 3 interventions per week within a 2-week period, when data of physiologic and developmental domains were collected before, during, and after the interventions or no interventions and daily during a 2-week period.
RESULTS: Three live music interventions showed changes in heart rate interactive with time. Lower heart rates occurred during the lullaby (P < .001) and rhythm intervention (P = .04). Sucking behavior showed differences with rhythm sound interventions (P = .03). Entrained breath sounds rendered lower heart rates after the intervention (P = .04) and differences in sleep patterns (P < .001). Caloric intake (P = .01) and sucking behavior (P = .02) were higher with parent-preferred lullabies. Music decreased parental stress perception (P < .001).
CONCLUSIONS: The informed, intentional therapeutic use of live sound and parent-preferred lullabies applied by a certified music therapist can influence cardiac and respiratory function. Entrained with a premature infant’s observed vital signs, sound and lullaby may improve feeding behaviors and sucking patterns and may increase prolonged periods of quiet–alert states. Parent-preferred lullabies, sung live, can enhance bonding, thus decreasing the stress parents associate with premature infant care.
Developmental Trends in Peer Victimization and Emotional Distress in LGB and Heterosexual Youth
Developmental Trends in Peer Victimization and Emotional Distress in LGB and Heterosexual Youth
Source: Pediatrics
OBJECTIVES: This study had 2 objectives: Our first objective was to provide the first evidence of developmental trends in victimization rates for lesbian, gay, and bisexual (LGB)- and heterosexual-identified youth, both in absolute and relative terms, and to examine differences by gender. Our second objective was to examine links between victimization, sexual identity, and later emotional distress.
METHODS: Data are from a nationally representative prospective cohort study of youth in England were collected annually between 2004 and 2010. Our final analytic dataset includes 4135 participants with data at all 7 waves; 4.5% (n = 187) identified as LGB. Analyses included hierarchical linear modeling, propensity score matching, and structural equation modeling.
RESULTS: LGB victimization rates decreased in absolute terms. However, trends in relative rates were more nuanced: Gay/bisexual-identified boys became more likely to be victimized compared with heterosexual-identified boys (wave 1: odds ratio [OR] = 1.78, P = .011; wave 7: OR = 3.95, P = .001), whereas relative rates among girls approached parity (wave 1: OR = 1.95, P = .001; wave 7: OR = 1.18, P = .689), suggesting different LGB–heterosexual relative victimization rate trends for boys and girls. Early victimization and emotional distress explained about 50% of later LGB–heterosexual emotional distress disparities for both boys and girls (each P < .015).
CONCLUSIONS: Victimization of LGB youth decreases in absolute, but not necessarily relative, terms. The findings suggest that addressing LGB victimization during adolescence is critical to reducing LGB–heterosexual emotional distress disparities but additional support may be necessary to fully eliminate these disparities.
Early Adolescent Music Preferences and Minor Delinquency
Early Adolescent Music Preferences and Minor Delinquency (PDF)
Source: Pediatrics
OBJECTIVES:
To test Music Marker Theory (MMT) positing that early adolescents’ preferences for nonmainstream types of popular music indicate concurrent and later minor delinquency.
METHODS:
MMT was tested in a 4-year longitudinal study (n = 309).
RESULTS:
The results showed that early fans of different types of rock (eg, rock, heavy metal, gothic, punk), African American music (rhythm and blues, hip-hop), and electronic dance music (trance, techno/ hardhouse) showed elevated minor delinquency concurrently and longitudinally. Preferring conventional pop (chart pop) or highbrow music (classic music, jazz), in contrast, was not related to or was negatively related to minor delinquency.
CONCLUSIONS:
Early music preferences emerged as more powerful indicators of later delinquency rather than early delinquency, indicating that music choice is a strong marker of later problem behavior. The mechanisms through which music preferences are linked to minor delinquency are discussed within the framework of MMT. Pediatrics 2013;131:1–10
Clinical Report: Organic Foods: Health and Environmental Advantages and Disadvantages
Clinical Report: Organic Foods: Health and Environmental Advantages and Disadvantages
Source: Pediatrics
The US market for organic foods has grown from $3.5 billion in 1996 to $28.6 billion in 2010, according to the Organic Trade Association. Organic products are now sold in specialty stores and conventional supermarkets. Organic products contain numerous marketing claims and terms, only some of which are standardized and regulated.
In terms of health advantages, organic diets have been convincingly demonstrated to expose consumers to fewer pesticides associated with human disease. Organic farming has been demonstrated to have less environmental impact than conventional approaches. However, current evidence does not support any meaningful nutritional benefits or deficits from eating organic compared with conventionally grown foods, and there are no well-powered human studies that directly demonstrate health benefits or disease protection as a result of consuming an organic diet. Studies also have not demonstrated any detrimental or disease-promoting effects from an organic diet. Although organic foods regularly command a significant price premium, well-designed farming studies demonstrate that costs can be competitive and yields comparable to those of conventional farming techniques. Pediatricians should incorporate this evidence when discussing the health and environmental impact of organic foods and organic farming while continuing to encourage all patients and their families to attain optimal nutrition and dietary variety consistent with the US Department of Agriculture’s MyPlate recommendations.
This clinical report reviews the health and environmental issues related to organic food production and consumption. It defines the term “organic,” reviews organic food-labeling standards, describes organic and conventional farming practices, and explores the cost and environmental implications of organic production techniques. It examines the evidence available on nutritional quality and production contaminants in conventionally produced and organic foods. Finally, this report provides guidance for pediatricians to assist them in advising their patients regarding organic and conventionally produced food choices.

Policy Statement: Cheerleading Injuries: Epidemiology and Recommendations for Prevention
Source: Pediatrics
Over the last 30 years, cheerleading has increased dramatically in popularity and has evolved from leading the crowd in cheers at sporting events into a competitive, year-round sport involving complex acrobatic stunts and tumbling. Consequently, cheerleading injuries have steadily increased over the years in both number and severity. Sprains and strains to the lower extremities are the most common injuries. Although the overall injury rate remains relatively low, cheerleading has accounted for approximately 66% of all catastrophic injuries in high school girl athletes over the past 25 years. Risk factors for injuries in cheerleading include higher BMI, previous injury, cheering on harder surfaces, performing stunts, and supervision by a coach with low level of training and experience. This policy statement describes the epidemiology of cheerleading injuries and provides recommendations for injury prevention.
Background Television in the Homes of US Children
Background Television in the Homes of US Children
Source: Pediatrics
OBJECTIVE: US parents were surveyed to determine the amount of background television that their children are exposed to as well as to isolate demographic factors associated with increased exposure to background television. After this, we ask how certain home media practices are linked to children’s background television exposure.
METHODS: US parents/caregivers (N = 1454) with 1 child between the ages of 8 months and 8 years participated in this study. A nationally representative telephone survey was conducted. Parents were asked to report on their child’s exposure to background television via a 24-hour time diary. Parents were also asked to report relevant home media behaviors related to their child: bedroom television ownership, number of televisions in the home, and how often a television was on in the home.
RESULTS: The average US child was exposed to 232.2 minutes of background television on a typical day. With the use of multiple regression analysis, we found that younger children and African American children were exposed to more background television. Leaving the television on while no one is viewing and children’s bedroom television ownership were associated with increased background television exposure.
CONCLUSIONS: Although recent research has shown the negative consequences associated with background television, this study provides the first nationally representative estimates of that exposure. The amount of exposure for the average child is startling. This study offers practitioners potential pathways to reduce exposure.
The Role of Herd Immunity in Parents’ Decision to Vaccinate Children: A Systematic Review
The Role of Herd Immunity in Parents’ Decision to Vaccinate Children: A Systematic Review
Source: Pediatrics
BACKGROUND AND OBJECTIVE: Herd immunity is an important benefit of childhood immunization, but it is unknown if the concept of benefit to others influences parents’ decisions to immunize their children. Our objective was to determine if the concept of “benefit to others” has been found in the literature to influence parents’ motivation for childhood immunization.
METHODS: We systematically searched Medline through October 2010 for articles on parental/guardian decision-making regarding child immunization. Studies were included if they presented original work, elicited responses from parents/guardians of children <18 years old, and addressed vaccinating children for the benefit of others.
RESULTS: The search yielded 5876 titles; 91 articles were identified for full review. Twenty-nine studies met inclusion criteria. Seventeen studies identified benefit to others as 1 among several motivating factors for immunization by using interviews or focus groups. Nine studies included the concept of benefit to others in surveys but did not rank its relative importance. In 3 studies, the importance of benefit to others was ranked relative to other motivating factors. One to six percent of parents ranked benefit to others as their primary reason to vaccinate their children, and 37% of parents ranked benefit to others as their second most important factor in decision-making.
CONCLUSIONS: There appears to be some parental willingness to immunize children for the benefit of others, but its relative importance as a motivator is largely unknown. Further work is needed to explore this concept as a possible motivational tool for increasing childhood immunization uptake.
A Systematic Review of Vocational Interventions for Young Adults With Autism Spectrum Disorders
A Systematic Review of Vocational Interventions for Young Adults With Autism Spectrum Disorders
Source: Pediatrics
BACKGROUND AND OBJECTIVE: Many individuals with autism spectrum disorders (ASDs) are approaching adolescence and young adulthood; interventions to assist these individuals with vocational skills are not well understood. This study systematically reviewed evidence regarding vocational interventions for individuals with ASD between the ages of 13 and 30 years.
METHODS: The Medline, PsycINFO, and ERIC databases (1980–December 2011) and reference lists of included articles were searched. Two reviewers independently assessed each study against predetermined inclusion/exclusion criteria. Two reviewers independently extracted data regarding participant and intervention characteristics, assessment techniques, and outcomes, and assigned overall quality and strength of evidence ratings based on predetermined criteria.
RESULTS: Five studies were identified; all were of poor quality and all focused on on-the-job supports as the employment/vocational intervention. Short-term studies reported that supported employment was associated with improvements in quality of life (1 study), ASD symptoms (1 study), and cognitive functioning (1 study). Three studies reported that interventions increased rates of employment for young adults with ASD.
CONCLUSIONS: Few studies have been conducted to assess vocational interventions for adolescents and young adults with ASD. As such, there is very little evidence available for specific vocational treatment approaches as individuals transition to adulthood. All studies of vocational approaches were of poor quality, which may reflect the recent emergence of this area of research. Individual studies suggest that vocational programs may increase employment success for some; however, our ability to understand the overall benefit of supported employment programs is limited given the existing research.

Male circumcision is a common procedure, generally performed during the newborn period in the United States. In 2007, the American Academy of Pediatrics (AAP) formed a multidisciplinary task force of AAP members and other stakeholders to evaluate the recent evidence on male circumcision and update the Academy’s 1999 recommendations in this area. Evaluation of current evidence indicates that the health benefits of newborn male circumcision outweigh the risks and that the procedure’s benefits justify access to this procedure for families who choose it. Specific benefits identified included prevention of urinary tract infections, penile cancer, and transmission of some sexually transmitted infections, including HIV. The American College of Obstetricians and Gynecologists has endorsed this statement.
Weight Status Among Adolescents in States That Govern Competitive Food Nutrition Content
Weight Status Among Adolescents in States That Govern Competitive Food Nutrition Content
Source: Pediatrics
OBJECTIVES:
To determine if state laws regulating nutrition content of foods and beverages sold outside of federal school meal programs (“competitive foods”) are associated with lower adolescent weight gain.
METHODS:
The Westlaw legal database identified state competitive food laws that were scored by using the Classification of Laws Associated with School Students criteria. States were classified as having strong, weak, or no competitive food laws in 2003 and 2006 based on law strength and comprehensiveness. Objective height and weight data were obtained from 6300 students in 40 states in fifth and eighth grade (2004 and 2007, respectively) within the Early Childhood Longitudinal Study–Kindergarten Class. General linear models estimated the association between baseline state laws (2003) and within-student changes in BMI, overweight status, and obesity status. Fixed-effect models estimated the association between law changes during follow-up (2003–2006) and within-student changes in BMI and weight status.
RESULTS:
Students exposed to strong laws at baseline gained, on average, 0.25 fewer BMI units (95% confidence interval: −0.54, 0.03) and were less likely to remain overweight or obese over time than students in states with no laws. Students also gained fewer BMI units if exposed to consistently strong laws throughout follow-up (β = −0.44, 95% confidence interval: −0.71, −0.18). Conversely, students exposed to weaker laws in 2006 than 2003 had similar BMI gain as those not exposed in either year.
CONCLUSIONS:
Laws that regulate competitive food nutrition content may reduce adolescent BMI change if they are comprehensive, contain strong language, and are enacted across grade levels.
Physical Punishment and Mental Disorders: Results From a Nationally Representative US Sample
Physical Punishment and Mental Disorders: Results From a Nationally Representative US Sample (PDF)
Source: Pediatrics
BACKGROUND: The use of physical punishment is controversial. Few studies have examined the relationship between physical punishment and a wide range of mental disorders in a nationally representative sample. The current research investigated the possible link between harsh physical punishment (ie, pushing, grabbing, shoving, slapping, hitting) in the absence of more severe child maltreatment (ie, physical abuse, sexual abuse, emotional abuse, physical neglect, emotional neglect, exposure to intimate partner violence) and Axis I and II mental disorders.
METHODS: Data were from the National Epidemiologic Survey on Alcohol and Related Conditions collected between 2004 and 2005 (N = 34 653). The survey was conducted with a representative US adult population sample (aged ≥20 years). Statistical methods included logistic regression models and population-attributable fractions.
RESULTS: Harsh physical punishment was associated with increased odds of mood disorders, anxiety disorders, alcohol and drug abuse/dependence, and several personality disorders after adjusting for sociodemographic variables and family history of dysfunction (adjusted odds ratio: 1.36–2.46). Approximately 2% to 5% of Axis I disorders and 4% to 7% of Axis II disorders were attributable to harsh physical punishment.
CONCLUSIONS: Harsh physical punishment in the absence of child maltreatment is associated with mood disorders, anxiety disorders, substance abuse/dependence, and personality disorders in a general population sample. These findings inform the ongoing debate around the use of physical punishment and provide evidence that harsh physical punishment independent of child maltreatment is related to mental disorders.
Injuries Associated With Bottles, Pacifiers, and Sippy Cups in the United States, 1991–2010
OBJECTIVE:To describe the epidemiology of injuries related to bottles, pacifiers, and sippy cups among young children in the United States.METHODS:A retrospective analysis was conducted by using data from the National Electronic Injury Surveillance System for children <3 years of age treated in emergency departments (1991–2010) for an injury associated with a bottle, pacifier, or sippy cup.RESULTS:An estimated 45 398 (95% confidence interval: 38 770–52 026) children aged <3 years were treated in emergency departments for injuries related to these products during the study period, an average of 2270 cases per year. Most injuries involved bottles (65.8%), followed by pacifiers (19.9%) and sippy cups (14.3%). The most common mechanism was a fall while using the product (86.1% of injuries). Lacerations comprised the most common diagnosis (70.4%), and the most frequently injured body region was the mouth (71.0%). One-year-old children were injured most often. Children who were aged 1 or 2 years were nearly 2.99 times (95% confidence interval: 2.07–4.33) more likely to sustain a laceration compared with any other diagnosis. Product malfunctions were relatively uncommon (4.4% of cases).CONCLUSIONS:This study is the first to use a nationally representative sample to examine injuries associated with these products. Given the number of injuries, particularly those associated with falls while using the product, greater efforts are needed to promote proper usage, ensure safety in product design, and increase awareness of American Academy of Pediatrics’ recommendations for transitioning to a cup and discontinuing pacifier use.
Pharmacy Communication to Adolescents and Their Physicians Regarding Access to Emergency Contraception
Pharmacy Communication to Adolescents and Their Physicians Regarding Access to Emergency Contraception (PDF)
Source: Pediatrics
OBJECTIVE: Emergency contraception (EC) is an effective pregnancy prevention strategy. EC is available without a prescription to those aged 17 years or older. The objective of this study was to assess the accuracy of information provided to adolescents and their physicians when they telephone pharmacies to inquire about EC.
METHODS: By using standardized scripts, female callers telephoned 943 pharmacies in 5 US cities posing as 17-year-old adolescents or as physicians calling on behalf of their 17-year-old patients. McNemar tests were used to compare outcomes between adolescent and physician callers.
RESULTS: Seven hundred fifty-nine pharmacies (80%) indicated to adolescent callers, and 766 (81%) to physician callers, that EC was available on the day of the call. However, 145 pharmacies (19%) incorrectly told the adolescent callers that it would be impossible to obtain EC under any circumstances, compared with 23 pharmacies (3%) for physician callers. Pharmacies conveyed the correct age to dispense EC without a prescription in 431 adolescent calls (57%) and 466 physician calls (61%). Compared with physician callers, adolescent callers were put on hold more often (54% vs 26%) and spoke to self-identified pharmacists less often (3% vs 12%, P < .0001). When EC was not available, 36% and 33% of pharmacies called by adolescents and physicians respectively offered no additional suggestions on how to obtain it.
CONCLUSIONS: Most pharmacies report having EC in stock. However, misinformation regarding who can take EC, and at what age it is available without a prescription, is common. Such misinformation may create barriers to timely access.

Stair-Related Injuries to Young Children Treated in US Emergency Departments, 1999–2008
Source: Pediatrics
OBJECTIVE: The objective of this study was to investigate the epidemiologic characteristics and secular trends of stair-related injuries among children aged <5 years treated in US emergency departments.
METHODS: A retrospective analysis was conducted of data from the National Electronic Injury Surveillance System of the US Consumer Product Safety Commission from 1999 through 2008 by using sample weights to estimate national numbers and rates of stair-related injuries.
RESULTS: An estimated 931 886 children aged <5 years were treated for stair-related injuries from 1999 through 2008, averaging 93 189 injuries per year and 46.5 injuries per 10 000 population annually. The number of injuries per year decreased significantly by 11.6% from 1999 to 2008. The rate of stair-related injuries also decreased significantly from 53.0 to 42.4 per 10 000 population from 1999 to 2008. Soft tissue injuries accounted for 34.6% of cases. Approximately three-fourths (76.3%) of children had injuries to the head and neck region, and 2.7% of patients were hospitalized. Children who were being carried at the time of injury accounted for 24.5% of injuries among children <1 year and were more than 3 times more likely to be hospitalized than children injured by other mechanisms.
CONCLUSIONS: Stair-related injuries are on the decline but still represent an important source of injury to young children. Increased prevention efforts are needed, including parental education and improved stairway design, to decrease stair-related injuries among young children.

Contemporary Ethical Issues in Human Milk-Banking in the United States
Contemporary Ethical Issues in Human Milk-Banking in the United States
Source: Pediatrics
Donor human milk has been used in the United States for >90 years, but recent advances in human milk science and laboratory techniques have led to increasing use of this resource. Pediatricians began using donor human milk in the 1900s in response to anecdotal observation that premature infants had better health outcomes when receiving their own mothers’ milk. Since then, a formalized human milk-banking system developed in the mid-1980s and distributed >1 million ounces of pasteurized donor human milk in 2008. Despite growth in the use of pasteurized donor human milk, there is little discussion in the medical literature regarding the ethical considerations of collection and use of this resource. Key ethical considerations include issues surrounding medical decision-making and informed consent, increasing the limited supply of human milk, how ethically to allocate this scarce resource, and concerns linked to the marketing of a human milk.

Temperature of Foods Sent by Parents of Preschool-aged Children (PDF)
Source: Pediatrics
Objective: To measure the temperatures of foods in sack lunches of preschool-aged children before consumption at child care centers.
Methods: All parents of 3- to 5-year-old children in full-time child care at 9 central Texas centers were invited to participate in the study. Foods packed by the parents for lunch were individually removed from the sack and immediately measured with noncontact temperature guns 1.5 hours before food was served to the children. Type of food and number of ice packs in the lunch sack were also recorded. Descriptive analyses were conducted by using SPSS 13.0 for Windows.
Results: Lunches, with at least 1 perishable item in each, were assessed from 235 parent-child dyads. Approximately 39% (n = 276) of the 705 lunches analyzed had no ice packs, 45.1% (n = 318) had 1 ice pack, and 88.2% (n = 622) of lunches were at ambient temperatures. Only 1.6% (n = 22) of perishable items (n = 1361) were in the safe temperature zone. Even with multiple ice packs, the majority of lunch items (>90%) were at unsafe temperatures.
Conclusions: These results provide initial data on how frequently sack lunches sent by parents of preschool-aged children are kept at unsafe temperatures. Education of parents and the public must be focused on methods of packing lunches that allow the food to remain in the safe temperature zone to prevent foodborne illness.
Profanity in Media Associated With Attitudes and Behavior Regarding Profanity Use and Aggression
Profanity in Media Associated With Attitudes and Behavior Regarding Profanity Use and Aggression (PDF)
Source: Pediatrics
Objective: We hypothesized that exposure to profanity in media would be directly related to beliefs and behavior regarding profanity and indirectly to aggressive behavior.
Methods: We examined these associations among 223 adolescents attending a large Midwestern middle school. Participants completed a number of questionnaires examining their exposure to media, attitudes and behavior regarding profanity, and aggressive behavior.
Results: Results revealed a positive association between exposure to profanity in multiple forms of media and beliefs about profanity, profanity use, and engagement in physical and relational aggression. Specifically, attitudes toward profanity use mediated the relationship between exposure to profanity in media and subsequent behavior involving profanity use and aggression.
Conclusions: The main hypothesis was confirmed, and implications for the rating industry and research field are discussed.
Policy Statement—Climatic Heat Stress and Exercising Children and Adolescents
Policy Statement—Climatic Heat Stress and Exercising Children and Adolescents (PDF)
Source: Pediatrics
Results of new research indicate that, contrary to previous thinking, youth do not have less effective thermoregulatory ability, insufficient cardiovascular capacity, or lower physical exertion tolerance compared with adults during exercise in the heat when adequate hydration is maintained. Accordingly, besides poor hydration status, the primary determinants of reduced performance and exertional heat-illness risk in youth during sports and other physical activities in a hot environment include undue physical exertion, insufficient recovery between repeated exercise bouts or closely scheduled same-day training sessions or rounds of sports competition, and inappropriately wearing clothing, uniforms, and protective equipment that play a role in excessive heat retention. Because these known contributing risk factors are modifiable, exertional heat illness is usually preventable. With appropriate preparation, modifications, and monitoring, most healthy children and adolescents can safely participate in outdoor sports and other physical activities through a wide range of challenging warm to hot climatic conditions.
