(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. Trend of PSY-HC affected mainly 15-years-olds: rates among boys varied from 29.6% to 35.9% (OR: 1.13, 95%CI: 1.02–1.25); among girls from 49.1% to 63.3% (OR: 1.56, 95%CI: 1.42–1.72). High school work pressure and poor social support play a central role in worsening well-being outcomes; (4) Conclusions: Our findings pictured a remarkable worsening trend of teenagers’ well-being, especially among 15-year-old girls. Further research will be required to investigate this breaking up of the connection between psychophysical symptomatology and cognitive perception of life satisfaction.

(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. Among 13- and 15-year-old girls, a jump from one to the other mental condition was observed in the 2014–2018 and 2010–2014 time periods, respectively; (4) Conclusions: Our findings suggest that Italian adolescents, especially older girls, have been shifting from Complete Mental Health to Incomplete Mental Illness in the last decade. Further research is needed to investigate this breaking up of the connection between psychological symptomatology and cognitive perception of life satisfaction.

(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. (3) Results: An overall declining trend in alcohol consumption was observed over time in almost all the countries. However, compared to 2014, some countries showed a new increase in 2018 and 2021/22 estimates forecast a slight increase in the majority of countries, pointing out a potential bounce after a decreasing period in frequent drinking habits. (4) Conclusions: The clusterization suggested a homogenization of consumption habits among HBSC countries. The comparison between 2022 observed and expected data could be helpful to investigate the effect of risk behaviour determinants, including the pandemic impact, occurring between the last two waves of the survey.

Background: The impact of the COVID-19 pandemic on adolescent suicidality is still controversial. The present systematic review and meta analysis aim to summarise findings from emerging literature about prevalences of the main suicidal outcomes among children and adolescents under 19 years old, and to compare them with the pre-pandemic period. Methods: Five databases (PubMed, Embase, Scopus, CINAHL and Web of Science) were systematically searched for studies published in English from January 1st, 2020 until November 3rd, 2021, reporting prevalence for suicidal ideation (SI), suicidal behaviors (SB) and suicide (S) in the general population aged <19 during the COVID-19 pandemic. Single-study prevalence data were pooled using random-effects meta-analysis. If studies reported prevalence estimates for both pre- and during-pandemic periods, prevalence ratio (PR) comparing the two periods has been computed and pooled. Results: Sixteen observational studies were selected: 10 about SI, 9 about SB and 3 about S. During the pandemic, prevalence of SI among adolescents was 21% (95% CI 12-34%) while prevalence of SB was 3% (95% CI 1-10%). Comparing pre- and during- pandemic prevalences, a significant overall increase in SB was observed (PR 1.35; 95% CI 1.06-1.72) while the prevalence rates of SI remained substantially steady (PR 0.95; 95% CI 0.64-1.39). A narrative review on the population-based data on suicide rates suggested an escalating trend since Summer 2020, after an initial stability of the phenomenon. Conclusions: During the COVID-19 pandemic SB showed a 35% increase and suicides rates escalated after a initial stability. School closures might be involved, representing an initial protective factor for suicidality, while after the reopenings we could have assisted to a suicide rebound, especially among the most vulnerable young people. Key messages: • The topic of suicidality among young people is still affected by a cultural stigma that hampers the development of both academic research, early detection and preventive policies. • The increase in suicidal behaviors among youths after the COVID-19 outbreak highlights a major public health issue that requires adequate supporting policies to control and prevent this phenomenon.

Background: Over the last decade, trends of suicidality among adolescents remain unclear. We conducted a cross-sectional study using surveillance data collected over the past 10 years in the Piedmont region, Italy, to explore temporal trends in suicidality among hospitalized adolescents. Methods: This was a retrospective study over an 11-year period of time. The target cohort was adolescents aged 13-19 discharged from inpatient/day-hospital care with at least one suicidality-related ICD9-CM code (i.e., suicidal ideation-SI, suicidal risk-SR and suspected suicide-SS) between 2011 and 2021 in Piedmont (Northwestern Italy). Social-economic related data is available from Census 2011. Yearly incidence rates (IR) were calculated based on the overall hospitals’ catchment population and by sex. Poisson regression model was estimated to evaluate the trend over time and the association with sex, and a potential effect of the COVID-19 pandemic. A non-linear trend was allowed by modelling natural splines. Results: We included 490 adolescents (median age: 15 years, IQR: 13-16), 380 girls and 110 boys, with ICD9-CM codes for SI (264; 53.9%), SR (142; 29%), SS (90; 18.4%) at first discharge. Girls showed a higher risk of repeated inpatient care than boys (19.2% vs 7.3%, p < 0.01). Since 2013, yearly suicidality IRs started increasing linearly in boys (+1.7/100,000 per year, 95%CI: 0.7-2.8). Apparently, suicidality IRs increasing in girls were observed since 2011 (+5.8/100,000 per year, 95%CI 2.8-8.9) and were significantly higher than in boys (p < 0.001). Conclusions: Suicidality among young inpatients increased in Piedmont during the last decade. Females seemed to be more affected than males. Further research is needed to better understand gender-related risk factors for suicidality. Key messages: • There has been an increase in the number of adolescents reporting suicidal ideation in the last decade, especially in girls. • Intervention strategies are urgently needed to reverse a potentially alarming trend in suicidality among young people.
