Pubertal Timing and Adolescent Alcohol Use: The Mediating Role of Parental and Peer Influences

Pubertal development at age 14 is associated with male adolescents' combustible cigarette smoking and dual use, but not with e-cigarette use - Findings from the UK Millennium Cohort Study

BACKGROUND

Adolescent nicotine exposure via electronic cigarettes (e-cigarettes) is a global health concern. Pubertal development earlier than peers increases the risk of tobacco smoking compared to peers experiencing on-time or late maturation, yet relationships of pubertal timing with e-cigarettes are unknown. We examine whether early pubertal timing is associated with risk for e-cigarette use, tobacco cigarettes, or both by age 14.

METHODS

The Millennium Cohort Study follows a representative cohort of 18,552 9-month-old children born 2000-2002 in the United Kingdom. Our sample includes 11,445 adolescents (5697 boys, 5748 girls) classified at age 14 as early, on-time, or late in pubertal development timing (PDT) relative to same-age, same-sex peers using the Pubertal Development Scale. Outcomes were use of e-cigarettes, tobacco cigarettes, or both by age 14. We included childhood liability confounders and demographics measured from age 7-11.

RESULTS

For girls, no PDT differences in age 14 e-cigarette or tobacco cigarette use were observed. All relative to on-time PDT boys, early maturing boys' odds of tobacco cigarette use were 59% higher (OR=1.59, 95% confidence interval (CI)=1.08,2.35), and odds of dual-use were 49% higher (OR=1.49, CI=1.11,1.99), both compared to odds of never use. Among late PDT boys, dual-use odds were lower than never use by 35% (OR=0.65, CI=0.47,0.91) and lower than e-cigarette use only by 36% (OR=0.64, CI=0.42,0.97).

CONCLUSIONS

At age 14, PDT was not associated with e-cigarette use for either sex, yet it was linked with tobacco use and dual use among boys.

The role of parenting in developmental trajectories of risk for adolescent substance use: a bioecological systems cascade model

Parenting is a key influence and prevention target for adolescent substance use, and changes dramatically in form and function during adolescence. This theoretical synthesis reviews evidence of associations of substance use-specific parenting behaviors, dimensions, and styles with adolescent substance use, and integrates key developmental and family theories (e.g., bioecological, dynamical systems, family systems, developmental cascades) and methodological-conceptual advances to illustrate the complex role that parenting plays for the development of adolescent substance use in combination with child and contextual influences. The resulting bioecological systems cascade model centers the dynamic co-development of parenting and child influences in developmental cascades that lead to more or less risk for adolescent substance use. These trajectories are initiated by intergenerational influences, including genetics, parents' familial environments, and child-parent attachment. Culture and context influences are a holistic backdrop shaping parent-adolescent trajectories. Parenting is influences are conceptualized as a complex process by which specific parenting behaviors are informed by and accumulate into parenting dimensions which together comprise general parenting styles and are informed by the broader family context. The co-development of parenting and child biobehavioral risk is shaped by both parents and children, including by the genetics and environments they do and do not share. This co-development is dynamic, and developmental transitions of individuals and the family lead to periods of increased lability or variability that can change the longer-term trajectories of children's risk for substance use. Methodological avenues for future studies to operationalize the model are discussed.

Visualization analysis of junior school students' pubertal timing and social adaptability using data mining approaches

Pubertal timing and social adaptability are important research contents of adolescent mental health education. Traditional research methods mainly classify students based on the total score or average score of the scale, although this kind of method is simple easy to conduct, it can't make a more detailed analysis of the students. In this paper, data mining methods such as association rules and clustering are used to analyze the data of pubertal timing and social adaptability scale, some novel and meaningful conclusions are figured out from the analysis results that can't be obtained by the previous methods, and the analysis results are visualized to enhance readability. Association rule mining on basic attributes information, the pubertal timing group and the social adaptability levels were performed which can explore the relationship between the basic attributes information of the students, pubertal timing and the social adaptability. Fine-grained analysis of social adaptability by using clustering method was conducted which can divide the similar students into the same groups that is very useful for teachers to have a more in-depth, accurate and detailed understanding of students, make sure that the better classification can be obtained compared with the traditional analysis approaches. The work of this paper provides an effective guidance and a novel perspective for how to use data mining technologies to study the pubertal timing and social adaptability problems.

•

Data mining is a new way to study pubertal timing and social adaptability problems.

•

Clustering method can divide the similar students in many aspects into the same group.

•

The radar chart shows that the role of each subscale is different.

•

Data mining methods can help teachers to have detailed understanding of students.

An Intersectional-Contextual Approach to Racial Trauma Exposure Risk and Coping Among Black Youth

Black youth experience racial discrimination at higher rates than other racial/ethnic groups in the United States. To identify how racism can simultaneously serve as a risk factor for adverse childhood experience (ACE) exposure, a discrete type of ACE, and a post-ACE mental health risk factor among Black youth, Bernard and colleagues (2021) proposed the culturally informed ACEs (C-ACE) model. While an important addition to the literature, the C-ACE model is framed around a single axis of race-based oppression. This paper extends the model by incorporating an intersectional and ecodevelopmental lens that elucidates how gendered racism framed by historical trauma, as well as gender-based socialization experiences, may have implications for negative mental health outcomes among Black youth. Clinical and research implications are discussed.

"I Grew Up Amidst Alcohol and Drugs:" a Qualitative Study on the Lived Experiences of Parental Substance Use Among Adults Who Developed Substance Use Disorders Themselves

Experiencing parental substance use (PSU) has been associated with a heightened risk of developing substance use disorders (SUDs) in offspring. The primary goal of this study was to explore perspectives of adult children with lived experience of PSU who also developed SUDs themselves through first-hand experience. This study was conducted in Flanders (Belgium). A qualitative exploratory research design was applied. Seventeen semi-structured interviews were conducted with adult children of parents with SUDs (range: 29-48 years) who themselves had developed SUDs. All interviews were audio-taped and transcribed verbatim. Three overarching themes emerged through thematic analysis: 1) loneliness and neglect in childhood; 2) stigma and the self; and 3) the role of social connection in substance use and recovery. The narratives highlighted the central role of feelings of loneliness, isolation and belonging among children of parents with SUDs in childhood and adulthood. Increasing public awareness on the impact of PSU on children and accessible support is needed to overcome stigma and remove barriers to social inclusion for children of parents with SUDs. Findings may prove valuable in informing policy, program and treatment development aimed at breaking maladaptive intergenerational cycles.

The association between pubertal timing and quality of life among children and adolescents: a cross-sectional study in Chongqing, China

BACKGROUND

To determine the relationship between pubertal timing and quality of life (QOL) in children and adolescents and to provide a basis for QOL intervention in pubertal children in the future to promote good adaptation and healthy physical and mental development of children.

METHODS

The survey was conducted in one county using a stratified cluster sampling method. The five physiological change items of the Puberty Development Scale (PDS) were used to assess the timing of puberty in students. Compared to students of the same age and the same sex, students who scored higher than the mean + standard deviation (SD) of individual developmental scores were defined as an early pubertal timing group. A 39-item QOL Scale for Children in Puberty was used to assess the QOL of the respondents. Multiple linear regression models were fitted separately for boys and girls.

RESULTS

Of the 7223 students, 3754 (51.97%) were boys and 3469 (48.03%) were girls. The prevalence of early pubertal periods was 16.07%. The total QOL score in the early pubertal timing group (137.16 ± 18.67) was significantly lower than in the normal (on time) group (142.02 ± 17.98) and the late group (142.76 ± 18.35) (F = 37.311, P < 0.001). A multiple linear regression model showed that early pubertal timing was a risk factor for QOL (P < 0.0014), compared with normal and late pubertal timing.

CONCLUSIONS

The early pubertal timing was associated with poorer QOL in children and adolescents. More attention should be paid to children with early pubertal timing in intervening children's QOL during pubertal development. Future longitudinal studies are needed to confirm the association between pubertal timing and QOL.
