Background: The effects of early exposure to television remain poorly defined. Although some have speculated that television may be habit-forming, evidence is lacking especially in young children.

Objective: To test the hypothesis that television viewing in the first 4 years of life is associated with protesting having the television turned off at age 6.

Methods: We used data from the National Longitudinal Survey of Youth. Parents reported how much television their children watched before the age of 4. They also reported how often their children protested having the television turned off at age 6. Their responses to this question were dichotomized to almost never vs other. Multivariate logistic regression was used to test the independent association of early television watching with subsequent protest at turning off the television, controlling for externalizing behavior scores at age 6, parenting style, and other covariates.

Results: Data were available for 1331 children. Sixty-three percent of children protested having the television turned off at age 6. In a logistic regression model, hours of television viewed per day before age 4 was associated with increased odds of protesting at age 6 (1.08 [1.02-1.15]).

Conclusion: Early television exposure is associated with resistance to turning off the television at school age.

Objective. Cross-sectional research has suggested that television viewing may be associated with decreased attention spans in children. However, longitudinal data of early television exposure and subsequent attentional problems have been lacking. The objective of this study was to test the hypothesis that early television exposure (at ages 1 and 3) is associated with attentional problems at age 7.

Methods. We used the National Longitudinal Survey of Youth, a representative longitudinal data set. Our main outcome was the hyperactivity subscale of the Behavioral Problems Index determined on all participants at age 7. Children who were 1.2 standard deviations above the mean were classified as having attentional problems. Our main predictor was hours of television watched daily at ages 1 and 3 years.

Results. Data were available for 1278 children at age 1 and 1345 children at age 3. Ten percent of children had attentional problems at age 7. In a logistic regression model, hours of television viewed per day at both ages 1 and 3 was associated with attentional problems at age 7 (1.09 [1.03-1.15] and 1.09 [1.02-1.16]), respectively.

Conclusions. Early television exposure is associated with attentional problems at age 7. Efforts to limit television viewing in early childhood may be warranted, and additional research is needed.

Objective. To test the hypothesis that late adolescent drinking behavior (ages 17--20) is associated with harmful and binge drinking in early adulthood (ages 30--31).

Methods. We used the National Longitudinal Survey of Youth (NLSY), a nationally representative longitudinal data set. We used harmful and binge drinking at ages 17 to 20 to predict harmful and binge drinking at ages 30 to 31, stratifying for gender and controlling for confounders.

Results. Data were available on harmful drinking at both the adolescent and the early adult age period for 3790 individuals and on binge drinking for 2387 individuals. Harmful drinking during adolescence was significantly associated with harmful drinking at ages 30 to 31 for men only. Among male adolescents, 14% of harmful drinkers continued harmful drinking at ages 30 to 31, compared with 4% of nonharmful drinkers who became harmful drinkers. In Poisson regression models, binge drinking during adolescence was associated with binge drinking at ages 30 to 31 for both men and women, generating relative risks of 2.3 (95% confidence interval: 1.8--3.0) and 3.0 (95% confidence interval: 2.4--4.8), respectively. Half of binge-drinking male adolescents and one third of binge-drinking female adolescents engaged in binge drinking into early adulthood, compared with 19% for non--binge-drinking male adolescents and 8% of non--binge-drinking female adolescents.

Conclusions. Problem drinking during adolescence is associated with problem drinking in early adulthood. Efforts to prevent and treat adolescent problem drinking could have an impact on the progression of alcohol-related disease. [ABSTRACT FROM AUTHOR]

This study examined the association between early emotional support provided by parents and child internalizing and externalizing problems, using a nationally representative, longitudinal sample of 1361 children. Parental emotional support was assessed using the Home Observation for the Measurement of the Environment, incorporating both parent report and interviewer observation. We found that, controlling for child externalizing problems at age 6 years, parental emotional support at age 6 years was negatively related to child externalizing problems at age 8 years. A developmental model that assessed the timing of the emergence of this relationship was then analyzed by including parental emotional support at ages 2, 4, and 6 years as predictors of child externalizing problems at age 8 years. The developmental model suggested that less parental emotional support as early as age 2 years is associated with later externalizing problems in children. This study discusses the importance of very early parental emotional support in promoting positive child development.

Objective: To test the independent effects of television viewing in children before age 3 years and at ages 3 to 5 years on several measures of cognitive outcomes at ages 6 and 7 years.

Design: Using data from a nationally representative data set, we regressed 4 measures of cognitive development at ages 6 and 7 years on television viewing before age 3 years and at ages 3 to 5 years, controlling for parental cognitive stimulation throughout early childhood, maternal education, and IQ.

Results: Before age 3 years, the children in this study watched an average of 2.2 hours per day; at ages 3 to 5 years, the daily average was 3.3 hours. Adjusted for the covariates mentioned earlier, each hour of average daily television viewing before age 3 years was associated with deleterious effects on the Peabody Individual Achievement Test Reading Recognition Scale of 0.31 points (95% confidence interval [CI], –0.61 to –0.01 points), on the Peabody Individual Achievement Test Reading Comprehension Scale of 0.58 points (95% CI, –0.94 to –0.21 points), and on the Memory for Digit Span assessment from the Wechsler Intelligence Scales for Children of –0.10 points (95% CI, –0.20 to 0 points). For the Reading Recognition Scale score only, a beneficial effect of television at ages 3 to 5 years was identified, with each hour associated with a 0.51-point improvement in the score (95% CI, 0.17 to 0.85 points).

Conclusions: There are modest adverse effects of television viewing before age 3 years on the subsequent cognitive development of children. These results suggest that greater adherence to the American Academy of Pediatrics guidelines that children younger than 2 years not watch television is warranted.

Prior studies have consistently found the occurrence of depression to be higher among persons with lower socio-economic status (SES), but causal mechanisms for this relationship are often not well understood. For example, while depression has been shown to increase during spells of unemployment, little work has been done on job attributes that may be related to depression among employed people early in their careers. This study links the 1992 wave of the National Longitudinal Survey of Youth 1979 cohort, which included Depression symptom scores on the Center for Epidemiologic Studies Depression (CES-D) instrument, to the US Department of Labor's new occupational characteristics O*Net dataset. The resulting dataset includes information regarding depression, SES, and specific attributes of jobs held by the young adult respondents. Job attributes included measures of social status, interpersonal stressors, and physical conditions. Multivariate analysis revealed that for young men, higher job status is associated with lower CES-D scores. Higher scores on the opposition scale, which measures the extent to which employees are obliged to take a position opposed to others, is associated with higher CES-D scores. For young women, physically uncomfortable or dangerous jobs are associated with more depressive symptoms. Results are stratified by race/ethnicity. For Black men, unlike for White men or Latinos, job security is associated with fewer depressive symptoms; and for Latino men, but not for Black or White men, physically uncomfortable or dangerous jobs are associated with more depressive symptoms. For Black women, job status is associated with fewer depressive symptoms. We conclude that part of the SES-depression relationship may arise from the psychosocial aspects of jobs, which we have found to be significantly and meaningfully associated with depressive symptoms among employed young adults.

BACKGROUND: Bullying is a major public health issue, the risk factors for which are poorly understood.

OBJECTIVE: To determine whether cognitive stimulation, emotional support, and television viewing at age 4 years are independently associated with being a bully at ages 6 through 11 years.

METHODS: We used multivariate logistic regression, using data from the National Longitudinal Survey of Youth, to adjust for multiple confounding factors.

RESULTS: Parental cognitive stimulation and emotional support at age 4 years were each independently protective against bullying, with a significant odds ratio of 0.67 for both variables associated with a 1-SD increase (95% confidence interval, 0.54-0.82 for cognitive stimulation and 0.54-0.84 for emotional support). Each hour of television viewed per day at age 4 years was associated with a significant odds ratio of 1.06 (95% confidence interval, 1.02-1.11) for subsequent bullying. These findings persisted when we controlled for bullying behavior at age 4 years in a subsample of children for whom this measure was available.

CONCLUSION: The early home environment, including cognitive stimulation, emotional support, and exposure to television, has a significant impact on bullying in grade school.
