Health Psychology features research from Add Health

Using data from the National Longitudinal Study of Adolescent to Adult Health, researchers explored the link between socioeconomic adversity during childhood and teenage years and cardio-metabolic disease risk in young adulthood. They also focused on how psychosocial resources—such as self-esteem, personality, and education— might contribute to this disease risk. Kandauda Wickrama, Catherine Walker O’Neal, Tae-Kyoung Lee, and Thulitha Wickrama found that those who experienced socioeconomic adversity (low parental education, receiving social service benefits) in early life had a higher cardio-metabolic disease risk as a young adult; for women, having impaired psychosocial resources increased this risk. These findings show that early interventions are needed for children experiencing socioeconomic adversity in order to reduce the risk of health problems later in life.

Abstract

Purpose

To estimate smoking progression probabilities from adolescence to young adulthood and to estimate long-term health and medical cost impacts of preventing smoking in today’s adolescents.

Methods

Using data from the National Longitudinal Study of Adolescent Health (Add Health), we first estimated smoking progression probabilities from adolescence to young adulthood. Then, using the predicted probabilities, we estimated the number of adolescents who were prevented from becoming adult daily smokers as a result of a hypothetical 1 percentage point reduction in the prevalence of ever smoking in today’s adolescents. We further estimated lifetime medical costs saved and quality-adjusted life years (QALYs) gained as a result of preventing adolescents from becoming adult daily smokers. All costs were in 2010 dollars.

Results

Compared with never smokers, those who had tried smoking at baseline had higher probabilities of becoming current or former daily smokers at follow-up regardless of baseline grade or sex. A hypothetical 1 percentage point reduction in the prevalence of ever smoking in 24.5 million students in 7th–12th grades today could prevent 35,962 individuals from becoming a former daily smoker and 44,318 individuals from becoming a current daily smoker at ages 24–32 years. As a result, lifetime medical care costs are estimated to decrease by $1.2 billion and lifetime QALYs is estimated to increase by 98,590.

Conclusions

Effective smoking prevention programs for adolescents go beyond reducing smoking prevalence in adolescence; they also reduce daily smokers in young adulthood, increase QALYs, and reduce medical costs substantially in later life. This finding indicates the importance of continued investment in effective youth smoking prevention programs.

Add Health Study: Teens who skimp on sleep now have more drinking problems later

Using data from the National Longitudinal Study of Adolescent to Adult Health, researchers from Idaho State University examined the connections between poor adolescent sleep and substance-related problems. The research team of Maria M. Wong, Gail C. Robertson, and Rachel B. Dyson assessed sleep difficulties among teenagers as predictors of problems such as binge drinking, alcohol-related interpersonal problems, regretted sexual activities, illicit drug use, and drunk driving. They found that teens in middle and high school that had trouble sleeping were more likely to have substance-related problems a year later, and those who slept poorly during that second year also had a higher chance of substance-related problems when they were between 18 and 24 years old.

Read the NPR story here: Teens who skimp on sleep now have more drinking problems later (released on January 16, 2015 by Maanvi Singh).

Excerpt: “Researchers have known for a while that lack of sleep and alcohol use are related, says Maria Wong, a psychologist at Idaho State University who led the study. ‘This study shows that sleep issues can actually precede and even predict alcohol use later on.’

And the influence of sleep on drinking behaviors can be dramatic…. In the study, each extra hour of sleep the teens got corresponded with a 10 percent decrease in binge drinking.”

Add Health Study: The relationship between skin tone and school suspension for African Americans

Using data from the National Longitudinal Study of Adolescent to Adult Health and the National Longitudinal Survey of Youth, a research team from Villanova University and the University of Iowa examined the links between skin tone and school suspension. They found that, for African American girls, having darker skin significantly increased odds of suspension. In fact, girls with the darkest skin tone were three times as likely to be suspended compared to those with the lightest skin.

Read the New York Times story here: Schools’ Discipline for Girls Differs by Race and Hue (released on December 10, 2014 by Tanzina Vega).

Excerpt: “There are different gender expectations for black girls compared with white girls, said Lance Hannon… And, he said, there are different expectations within cross-sections of black girls. ‘When a darker-skinned African-American female acts up, there’s a certain concern about their boyish aggressiveness,’ Dr. Hannon said, ‘that they don’t know their place as a female, as a woman.’”

Add Health study recognized in the Journal of General Internal Medicine for comprehensive incarceration questions

 

In a review in the Journal of General Internal Medicine, the Add Health study was described as a leading source of “high-impact incarceration-related health research” among 36 major data sets related to incarceration. The Add Health survey employed a comprehensive approach which asked participants about incarceration status and detailed incarceration history in a manner that was appropriate for analysis by other researchers. Add Health also gathered valuable information about year, length, and family history of incarceration. This detailed information about incarceration is valuable in informing policy related to the growing cost of health care and incarceration.

Health Outcomes in Young Adults From Foster Care and Economically Diverse Backgrounds

Using data from both the National Longitudinal Study of Adolescent to Adult Health and the Midwest Evaluation of the Adult Functioning of Former Foster Youth, researchers explored the risk of health problems in former foster children. Kym R. Ahrens, Michelle M. Garrison, and Mark E. Courtney examined  whether young adults with a foster or economically insecure background had a greater risk of developing chronic health conditions, such as hypertension and diabetes, than young adults from economically secure backgrounds.  They found that those from an economically secure background had the lowest risk of chronic disease, and former foster children had the highest risk, even beyond  what could be attributed to  financial insecurity.  Former foster children and economically insecure young adults were also less likely to  have health insurance when compared to the economically secure group.

Washington Post & ABC News feature Add Health research on network ecology and adolescent social structure

Using longitudinal friendship data from the National Longitudinal Study of Adolescent to Adult Health, as well as individual classroom data from the Classroom Engagement Study, researchers explored social network differences among schools. The research team of Daniel A. McFarland, James W. Moody, David Diehl, Jeffrey A. Smith, and Reuben J. Thomas developed a theory of network ecology in order to explore how the features of a school environment, such as size and demographic composition, may influence the formation of social networks. They found that in larger schools the student body tends to be more segregated than in smaller schools, with higher prevalence of social hierarchies and clustering.  Social exclusion has a higher cost for students in smaller schools, and thus it happens less frequently. In larger schools, this exclusion cost is lower because there are more peers to form relationships with.

Read the ABC News story here: See If Your Kids’ School Is at Risk for Cliques (released on November 11, 2014 by Genevieve Shaw Brown).

Excerpt from The Washington Post: “At large schools where the student body is more diverse, students are compelled by a mixture of freedom and uncertainty to cluster into groups with others like themselves, an instinct called ‘homophily.’ At smaller schools, there’s a higher cost to excluding people because fewer students mean fewer potential friends, so cliques are less common.

But small schools and less choice isn’t necessarily better, McFarland cautioned: ‘What may work well for a shy child may not work well for a gregarious one, and neither solution may prepare them well for the realities of adulthood. We just need to study it and see.’”
