Positive youth, healthy adults: Does positive well-being in adolescence predict better perceived health and fewer risky health behaviors in young adulthood?

Lindsay T. Hoyt; P. Lindsay Chase-Lansdale; Thomas W. McDade; Emma K. Adam

PURPOSEnTo examine the prospective, longitudinal associations between positive well-being during adolescence and health outcomes in young adulthood, using a large, nationally representative sample of youth.nnnMETHODSnOn the basis of the data from the first three waves of the National Longitudinal Study of Adolescent Health, we examined positive well-being during adolescence (averaged across Waves I-II) as a predictor of perceived young adult general health and risky health behaviors (Wave III). Each model included a full set of health and demographic baseline covariates. Missing values were assigned using multiple imputation methods (n = 10,147).nnnRESULTSnPositive well-being during adolescence was significantly associated with reporting better perceived general health during young adulthood, independent of depressive symptoms. Positive well-being was also significantly associated with fewer risky health behaviors in Wave III, after adding all covariates, including depressive symptoms and baseline risky health behaviors.nnnCONCLUSIONnFew studies of adolescent health have examined positive psychological characteristics, tending to focus instead on the effect of negative mood states and cognitions on health. This study demonstrates that positive well-being during adolescence predicts better perceived general health and fewer risky health behaviors during young adulthood. Aligned with the goals of the positive youth development perspective, promoting and nurturing positive well-being during the transition from childhood to adolescence may present a promising way to improve long-term health.

Health-related behaviors in adolescence establish trajectories of risk for obesity and chronic degenerative diseases, and they represent an important pathway through which socio-economic environments shape patterns of morbidity and mortality. Most behaviors that promote health involve making choices that may not pay off until the future, but the factors that predict an individuals investment in future health are not known. In this paper we consider whether expectations for the future in two domains relevant to adolescents in the U.S.-perceived chances of living to middle age and perceived chances of attending college-are associated with an individuals engagement in behaviors that protect health in the long run. We focus on adolescence as an important life stage during which habits formed may shape trajectories of disease risk later in life. We use data from a large, nationally representative sample of American youth (the US National Longitudinal Study of Adolescent Health) to predict levels of physical activity, fast food consumption, and cigarette smoking in young adulthood in relation to perceived life chances in adolescence, controlling for baseline health behaviors and a wide range of potentially confounding factors. We found that adolescents who rated their chances of attending college more highly exercised more frequently and smoked fewer cigarettes in young adulthood. Adolescents with higher expectations of living to age 35 smoked fewer cigarettes as young adults. Parental education was a significant predictor of perceived life chances, as well as health behaviors, but for each outcome the effects of perceived life chances were independent of, and often stronger than, parental education. Perceived life chances in adolescence may therefore play an important role in establishing individual trajectories of health, and in contributing to social gradients in population health.

Associations between self-reported discrimination and diurnal cortisol rhythms among young adults: The moderating role of racial–ethnic minority status

Lindsay T. Hoyt; Emma K. Adam

Discrimination is theorized to set in motion a neuroendocrine response, which includes cortisol secretion from the hypothalamic-pituitary-adrenal axis. Repeated exposure to perceived discrimination is thought to contribute to alterations in diurnal cortisol rhythms and to have implications for health. Discrimination may have particularly strong effects on racial/ethnic minority individuals, based on histories of past exposure and/or greater perceived implications of discriminatory events. Utilizing an ethnically and racially diverse sample of young adults (N=140; Mage=22.8 years) and a multiple-day naturalistic cortisol protocol, the present study examined associations between self-reported discrimination and diurnal cortisol rhythms, and whether this relation was moderated by racial/ethnic minority status. Results revealed that self-reported discrimination predicted flatter diurnal cortisol slopes for racial/ethnic minority individuals only. These findings align with theory suggesting that discrimination experiences are important among racial/ethnic minorities.

PURPOSEnTo examine the associations between adverse interpersonal relationship histories experienced during adolescence and health in young adulthood in a large, nationally representative sample.nnnMETHODSnUsing data from Waves I, II, and III of the National Longitudinal Study of Adolescent Health, multiple adverse relationship experiences were examined, including high loneliness, low perceived parental support, frequent transitions in romantic relationships (relationship instability), exposure to intimate partner violence, and loss by death of important relationship figures. These histories are assessed, both individually and in a relationship risk index, as predictors of self-reported general health and depressive symptoms at Wave III (ages, 18-27), controlling for baseline (Wave I) health and for demographic and health behavior covariates.nnnRESULTSnNet of baseline health and covariates, each type of relationship risk (experienced between Wave I and Wave III) was related to either depression or general health at Wave III, with the strongest effects seen for exposure to intimate partner violence. In addition, a cumulative relationship risk index examining the extent to which youth experienced high levels of multiple relationship risk factors revealed that each additional adverse relationship experience increased the odds of reporting worse mental and general health at Wave III, with increases occurring in an additive manner.nnnCONCLUSIONnMultiple types of adverse relationship experiences predicted increases in poorer general health and depressive symptoms from adolescence to early adulthood. Consistent with a cumulative risk hypothesis, the more types of adverse relationship a youth experienced, the worse were their young adult health outcomes.

Diurnal alpha amylase patterns in adolescents: associations with puberty and momentary mood states.

Emma K. Adam; Lindsay T. Hoyt; Douglas A. Granger

Salivary alpha amylase (sAA) has been proposed as a marker of autonomic nervous system activity. Few studies have examined sAA basal activity and reactivity in naturalistic settings, or developmental changes in sAA. In 50 adolescents, diary-reported moods and sAA levels were gathered across two typical weekdays. As in adults, basal sAA levels were low at waking and increased across the day. More advanced pubertal development was associated with higher waking sAA levels; males had smaller sAA increases across the day. High arousal positive emotions (feeling strong, active, excited) were associated with acute sAA increases; high arousal negative emotions (angry, stressed, nervous, worried) predicted sAA increases among youth with high average levels of these emotions. Findings suggest that basal sAA levels increase with puberty, and that acute sAA increases may reflect levels of emotional arousal, including high arousal positive emotions, rather than being specific to stress or emotions of negative valence.

Puberty and perimenopause: Reproductive transitions and their implications for women's health

Lindsay T. Hoyt; April Falconi

This scoping review synthesizes existing research on two major transitions in females lives: puberty and perimenopause. These two periods of vast physiological change demarcate the beginning and the end of the reproductive life cycle and are associated with major neuroendocrine reorganization across two key systems, the hypothalamic-pituitary-gonadal (HPG) axis the hypothalamus-pituitary-adrenal (HPA) axis. Despite growing evidence suggesting that the timing and experience of puberty and perimenopause are related to various physical and mental health outcomes (e.g., mood disorders, metabolism, cardiovascular health, autoimmune conditions, and cancer), these two processes are rarely examined together. In this paper, we bridge these disparate literatures to highlight similarities, isolate inconsistencies, and identify important areas for future research in womens health.

Positive and Negative Affect and Arousal: Cross-Sectional and Longitudinal Associations with Adolescent Cortisol Diurnal Rhythms

Lindsay T. Hoyt; Michelle G. Craske; Susan Mineka; Emma K. Adam

Objectives Psychobiological research with adolescent populations tends to focus on negative mood, stress, and psychopathology, but the role of positive emotions is insufficiently understood. The current study examines the relative contributions of both negative and positive affective experiences to the basal activity of the hypothalamic-pituitary-adrenal axis, measured by levels of cortisol across the waking day. Methods A sample of 315 ethnically and racially diverse high school students (mean age = 17.1 years, 73% female) completed a multiple-day naturalistic salivary cortisol protocol twice over a 5-year period. Along with each saliva sample, youth provided diary reports of their current mood states. Principal components analysis revealed four factors: high arousal positive affect (PA), low arousal PA, high arousal negative affect (NA), and low arousal NA. Results Multilevel growth curve models suggested that greater high arousal PA was associated with adaptive patterns of hypothalamic-pituitary-adrenal activity: steeper cortisol slope from waking to bedtime and lower evening cortisol, independent of NA. In addition, increases in high arousal PA over the 5-year follow-up period were associated with a steepening of the diurnal cortisol slope (&bgr; = −0.038, p = .009; negative values indicate the decrease of cortisol throughout the day) and lower evening cortisol levels (&bgr; = −0.661, p = .027) based on within-person fixed-effect regression analysis. Conclusions This study shows that high arousal PA, such as feeling alert and active, is associated with a steeper decline in cortisol throughout the day. Low arousal positive emotions did not display this relationship.

Quality of relationships with parents and friends in adolescence predicts metabolic risk in young adulthood.

Katherine B. Ehrlich; Lindsay T. Hoyt; Jennifer A. Sumner; Thomas W. McDade; Emma K. Adam

OBJECTIVEnThis study was designed to examine whether family and peer relationships in adolescence predict the emergence of metabolic risk factors in young adulthood.nnnMETHODnParticipants from a large, nationally representative cohort study (N = 11,617 for these analyses) reported on their relationship experiences with parents and close friends during adolescence. Fourteen years later, interviewers collected blood samples, as well as anthropometric and blood pressure measurements. Blood samples were analyzed for HbA1c.nnnRESULTSnOrdered logistic regressions revealed that for females, supportive parent-child relationships and close male friendships in adolescence were associated with reduced odds of having elevated metabolic risk markers in young adulthood. These effects remained significant even after controlling for baseline measures of body mass index (BMI) and health and demographic covariates. The protective effects of close relationships were not significant for males, however. Exploratory analyses with 2-parent families revealed that supportive father-child relationships were especially protective for females.nnnCONCLUSIONSnThese findings suggest that, for females, close and supportive relationships with parents and male friends in adolescence may reduce the risk of metabolic dysregulation in adulthood.

Daily life with depressive symptoms: Gender differences in adolescents' everyday emotional experiences

Allison Frost; Lindsay T. Hoyt; Alissa Levy Chung; Emma K. Adam

Depression is a prevalent and debilitating illness facing many adolescents, especially adolescent girls, whose risk for this disorder is approximately twice that of boys. Many studies have identified mechanisms that place girls at higher risk for depression during adolescence. Few, however, have examined differences in the everyday emotional experiences of boys and girls with varying levels of depressive symptoms. Using the Experience Sampling Method, this study investigated the roles of gender and depressive symptomatology in the emotional experiences of a community sample of youth (11-18 year-olds) from the Sloan 500 Family Study. Females with higher levels of depressive symptoms were more likely than females with fewer depressive symptoms and all males to experience strong negative emotions and to attribute the cause of these emotions to other people. These results suggest that emotional reactivity in interpersonal contexts is especially important to understand gender differences in the daily experience of depressive symptoms.

BACKGROUND AND OBJECTIVES: The neighborhoods in which children live, play, and eat provide an environmental context that may influence obesity risk and ameliorate or exacerbate health disparities. The current study examines whether neighborhood characteristics predict obesity in a prospective cohort of girls. METHODS: Participants were 174 girls (aged 8–10 years at baseline), a subset from the Cohort Study of Young Girls’ Nutrition, Environment, and Transitions. Trained observers completed street audits within a 0.25-mile radius around each girl’s residence. Four scales (food and service retail, recreation, walkability, and physical disorder) were created from 40 observed neighborhood features. BMI was calculated from clinically measured height and weight. Obesity was defined as BMI-for-age ≥95%. Logistic regression models using generalized estimating equations were used to examine neighborhood influences on obesity risk over 4 years of follow-up, controlling for race/ethnicity, pubertal status, and baseline BMI. Fully adjusted models also controlled for household income, parent education, and a census tract measure of neighborhood socioeconomic status. RESULTS: A 1-SD increase on the food and service retail scale was associated with a 2.27 (95% confidence interval, 1.42 to 3.61; P < .001) increased odds of being obese. A 1-SD increase in physical disorder was associated with a 2.41 (95% confidence interval, 1.31 to 4.44; P = .005) increased odds of being obese. Other neighborhood scales were not associated with risk for obesity. CONCLUSIONS: Neighborhood food and retail environment and physical disorder around a girl’s home predict risk for obesity across the transition from late childhood to adolescence.
