This is why they are called “social” media! Nonlinear associations between time spent on social media and psychosocial well-being in a representative Italian sample
Associations between relative deprivation and problematic gaming in adolescence
BACKGROUND: Problematic gaming is a known risk factor for adolescent well-being. Yet, socioeconomic factors that might contribute to problematic gaming in adolescence have not been fully explored. This study examined the association between relative deprivation, defined as an individual's financial gap relative to their classmates, and problematic gaming in a representative sample of Italian adolescents. METHODS: We analysed data on family materi…
Problem gaming and adolescents’ health and well-being
Playing video games is a common leisure activity for adolescents, but a minority can develop maladaptive gaming patterns and experience impairments in various health domains. Most research has been conducted within the dichotomy of “non-problematic gaming” and “problematic gaming” with convenience and unrepresentative samples, necessitating further investigation to provide more robust and generalizable evidence. In this study, we examined the imp…
Health Profiles in Developmental Age
Background: The adoption of a healthy lifestyle and eating habits in children represents a major public health objective worldwide, with significant implications for the development of chronic non-communicable diseases in adulthood. In Italy, the "OKkio alla SALUTE" Surveillance System (National Institute of Health) has been in place since 2007 to periodically monitor the nutritional status and health-related behaviors of children aged 8 to 9 yea…
How Family Structure Can Influence Adolescents’ Eating Habits

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. Data from the 2017/18 Health Behavior in School-Aged Children survey in Italy were analyzed. The 18,794 participants included 15-year-olds, categorized as native or migrants, with ethnic background…
Trend of Correlations between Psychological Symptoms and Socioeconomic Inequalities among Italian Adolescents
Adolescence is a critical moment in life; people become individuals, create new relationships, develop social skills and learn behaviours that they will use for the rest of their lives. During this phase, adolescents establish patterns of behaviour that can protect their health. This study aims to 1. assess the presence of psychological disorders in adolescents of both genders, 2. determine their relation to socio-economic differences based on th…
Cross-national variation in the association between family structure and overweight and obesity
The study indicates that living in a one-parent family, as well as living together with grandparents, are associated with overweight and obesity among adolescents, particularly in the Nordic European region. Existing welfare policies may be insufficient to eliminate inequalities related to family structure differences
Physical Activity among Italian Adolescents
The aim of this study was to describe physical activity, both moderate-to-vigorous physical activity (MVPA) and vigorous physical activity (VPA), in a large nationally representative sample of Italian adolescents, aged 11, 13 and 15, and to evaluate if Italian adolescents were in line with the 2020 WHO recommendations. In order to assess the possible impact of physical activity on adolescent psychological and social wellbeing, the associations be…
The Effect of Problematic Social Media Use on Happiness among Adolescents
Background: Although the relationship between problematic social media use (PSMU) and happiness has been already explored, less is known about the mechanisms that translate PSMU into lower happiness through lifestyle habits. Therefore, the current study focuses on the association between PSMU and happiness, exploring a mediating effect of lifestyle habits (e.g., difficulties in getting to sleep and frequency of physical activity) among Italian ad…
Surveillance for Severe Acute Respiratory Infections among Hospitalized Subjects from 2015/2016 to 2019/2020 Seasons in Tuscany, Italy
In Italy, the influenza season lasts from October until April of the following year. Influenza A and B viruses are the two viral types that cocirculate during seasonal epidemics and are the main causes of respiratory infections. We analyzed influenza A and B viruses in samples from hospitalized patients at Le Scotte University Hospital in Siena (Central Italy). From 2015 to 2020, 182 patients with Severe Acute Respiratory Infections were enrolled…
The Contribution of Organised Leisure-Time Activities in Shaping Positive Community Health Practices among 13- and 15-Year-Old Adolescents
Background and Objective : Participation in organised out-of-school leisure-time activities (OLTAs) has been shown to have a positive impact on community health practices and to lessen inequities in social and environmental opportunities among youths. According to the social capital theory, OLTAs foster bridging ties that allow individuals to forge new, wider-ranging social connections, increasing social integration and opportunities for identity…
Being a Young Migrant in Italy

Objective The aim of the present study was to examine the prevalence and time trends in childhood overweight including obesity and obesity among Tuscan children from 2002 to 2012. Design Cross-sectional study at five time points (Tuscan Nutritional Surveillance Surveys conducted in the years of 2002, 2006, 2008, 2010 and 2012). Trained personnel directly measured the height and weight of the subjects. BMI was assessed by means of the Internationa…
Factors associated with unhealthy behaviours and health outcomes
Unhealthy behaviours are strongly related to the school environment and peer group. A negative school environment proved to have the strongest relation with poor health outcomes
Trends in thinness prevalence among adolescents in ten European countries and the USA (1998–2006)
Objective To describe the prevalence of ‘graded thinness’ in children aged 11, 13 and 15 years in eleven developed countries and to identify trends in the prevalence of ‘thinness’ (BMI 2 at age 18 years) by age and gender. Design Cross-sectional study using data collected through self-reported questionnaires. Setting Data were taken from the 1997/1998, 2001/2002 and 2005/2006 surveys of the Health Behaviours in School-aged Children (HBSC) Study. …
