Three Decades of Adolescent Health: Unveiling Global Trends Across 41 Countries in Psychological and Somatic Complaints (1994-2022).

Objectives: This study examined (non-)monotonic time trends in psychological and somatic complaints among adolescents, along with gender differences.

Methods: Repeated cross-sectional Health Behaviour in School-aged Children (HBSC) data from 1994 to 2022 covering 15-year-old adolescents from 41 countries (N = 470,797) were analysed. Three polynomial logistic regression models (linear, quadratic, cubic) were tested for best fit, including separate analyses by gender and health complaints dimension.

Stability of unilateral posterior crossbite treatment with the Function Generating Bite appliance : Association with reduction of mandibular clockwise rotation and increased maxillary transversal width measurements.

Purpose: This observational study aimed to evaluate the stability of unilateral posterior crossbite (UPXB) correction with the functional appliance function generating bite (FGB appliance) during follow-up and its effects on craniofacial growth.

Materials And Method: A total of 102 age- and gender-matched patients were included: 51 with UPXB (male [M] = 19; female [F] = 32; mean age ± standard deviation [SD] = 7.6 ± 1.

Well-being among university students in the post-COVID-19 era: a cross-country survey.

University students have to handle crucial challenges for their future lives, such as succeeding in academic studies and finding attachment figures. These processes could potentially involve their well-being and mental health, with possible sociocultural differences based on the country of study. In order to explore such potential differences, a cross-sectional, multi-center survey was performed involving students from the University of Torino (Italy), Sevilla (Spain), and Lusòfona (Portugal).

Adolescents perception of the COVID-19 pandemic restrictions and associated mental health and well-being: gender, age and socioeconomic differences in 22 countries.

Background: The COVID-19-pandemic has had a profound impact on the lives of adolescents worldwide. This study examined the subjective perception of the COVID-19 pandemic measures and its association with mental health and well-being (i.e.

Different Categories of Social Media Use and Their Association With Body Image Among Adolescents in 42 Countries.

Objectives: Social media has become integrated into adolescents' lives and influences body image perceptions. Our study examined four patterns of social media use (SMU): non-active, active, intensive, and problematic. We hypothesised that intensive SMU and problematic SMU would be associated with negative body image (negative subjective body weight) and over/underestimated body weight congruence, compared to non-active and active SMU.

Risk Behaviors among Migrant Adolescents in Italy.

Adolescence is a critical period for engaging in health risk behaviors. Migrant adolescents may face unique challenges due to acculturation stress. This study aims to monitor substance use and problem gambling among migrant adolescents living in Italy.

Who Stays, Who Moves on and the Host Population: A Picture of Adolescents' Perceived Well-Being and Risk Behaviours.

The study aims to evaluate the health profile of first- and second-generation Romanian immigrants living in Italy compared to their adolescent peers in the country of origin (Romania) and the host population (Italian-borns). Analyses were performed on the 2013/2014 Health Behaviour in School-aged Children (HBSC) survey data. Romanian natives showed lower levels of health complaints and higher life satisfaction than Romanian migrants, who were similar to the host population, especially the second-generation ones.

The wellbeing of adolescents and the role of greenness: A cross-sectional study among Italian students.

Introduction: Adolescence is a critical period of life, and the level of wellbeing acquired during this stage might have an influence on health status in adulthood. The wellbeing of adolescents is associated with both biological and environmental determinants. To date, few studies have evaluated the effect of exposure to urban green spaces (i.

The Mental Well-Being of Italian Adolescents in the Last Decade through the Lens of the Dual Factor Model.

(1) Background: In Italy, the components of adolescents' mental well-being (psychological symptomatology and cognitive perception of life satisfaction) showed different temporal trends, suggesting the adoption of a multidimensional conceptualization. We aimed to assess temporal patterns and provide additional insights into Italian adolescents' mental well-being in the last decade by adopting the Dual Factor Model; (2) Methods: We used nationally representative samples of Italian students (n = 165,000) aged 11, 13, and 15 years across the three more recent Italian Health Behaviour in School-aged Children (HBSC) surveys. Two measures of mental well-being were used: life satisfaction (LS, indicator of positive subjective well-being) and psychological health complaints (PHC, indicator of mental illness); (3) Results: Our study showed that the overall sample has been moving from a Complete Mental Health (Flourishing) to an Incomplete Mental Illness (Struggling) condition.

Forecasting Frequent Alcohol Use among Adolescents in HBSC Countries: A Bayesian Framework for Making Predictions.

(1) Aim: To summarize alcohol trends in the last 30 years (1985/6-2017/8) among 15-year-olds in Health Behaviour in School-aged Children (HBSC) countries (overall sample size: 413,399 adolescents; 51.55% girls) and to forecast the potential evolution in the upcoming 2021/22 HBSC survey. (2) Methods: Using 1986-2018 prevalence data on weekly alcohol consumption among 15-year-olds related to 40 HBSC countries/regions, a Bayesian semi-parametric hierarchical model was adopted to estimate trends making a clusterization of the countries, and to give estimates for the 2022 HBSC survey.

Mental Well-Being: 2010-2018 Trends among Italian Adolescents.

(1) Aims: To explore temporal trends 2010-2018 of well-being among Italian adolescents and to evaluate potential explanatory factors. (2) Methods: Italian nationality representative samples of students aged 11, 13, and 15 years were recruited in 2010, 2014, and 2018; Health Behaviour in School-aged Children (HBSC), for an overall number of 165,000 teenagers. Multivariable logistic regression models were performed to fit the trends over time of life satisfaction (LS), psychological (PSY-HC) and somatic health complaints (SOM-HC) considering the contextual factors: school work pressure, social support (family, school, peers), socioeconomic status, geographic area, and immigration background; (3) Results: From 2010 to 2018 while LS was steady, health complaints increased, mainly for PSY-HC, in all age and gender groups.
