Weight Reduction Behaviors Among European Adolescents : Changes From 2001/2002 to 2017/2018

Purpose The purpose of this study was to analyze changes in the prevalence of weight reduction behaviors (WRBs) among European adolescents from 26 countries between 2001/2002 and 2017/2018. The impact of the perception of body weight on WLB was also analyzed, with particular attention being paid to overestimation. Methods The data of 639,194 European adolescents aged 11, 13, and 15 years who participated in the Health Behaviour in School-aged Children survey were analyzed. Age-standardized prevalence rates of WRB were estimated separately by survey round and gender for each country, using the overall 2017/2018 Health Behaviour in School-aged Children study population as the standard.

Does health literacy explain the link between structural stratifiers and adolescent health?

Abstract Background The concept of health literacy (HL) may help us to better understand the mechanisms leading to health disparities, and to focus on the factors that can be influenced. However, not much is yet known about how HL is related to health disparities, or whether the association exists among adolescents. The aim of the study was to examine the associations between structural stratifiers, HL and health indicators among adolescents. Methods The nationally representative Finnish Health Behaviour in School-aged Children survey data (n=3833) were collected from 13- and 15-year-old pupils in the spring of 2014. Pearson correlation coefficients were calculated, and separate path models…

Breakfast consumption and its socio-demographic and lifestyle correlates in schoolchildren in 41 countries participating in the HBSC study

Objective: To investigate associations of daily breakfast consumption (DBC) with demographic and lifestyle factors in 41 countries. Methods: Design: Survey including nationally representative samples of 11–15 year olds (n = 204,534) (HBSC 2005–2006).

The Associations between Physical Activity and Body-Esteem in 15-Year-Old Adolescents : A Cross-Sectional Study from Finland

Purpose: Physical activity promotes a positive physical self-image, but less is known about whether the positive effect covers the general self-evaluation of adolescent appearance.

Cross-national time trends in adolescent body weight perception and the explanatory role of overweight/obesity prevalence

Introduction Body weight perception (BWP) is associated with health behaviors. Current evidence points to an increase over time in both actual and perceived weight status among adolescents, however there is limited evidence on time trends in BWP in cross-national samples of adolescents. Therefore, the aims of this study were to examine time trends in BWP between 2002 and 2018 among adolescents from 41 countries and regions, including gender and country differences and to explore the role of changes over time in country-level overweight/obesity prevalence in these trends. Methods Data were used from five cycles (2002, 2006, 2010, 2014, 2018) of the repeated cross-sectional Health Behavior in…

Problematic Social Media Use and Health among Adolescents

1) Background: The use of social media has become an integral part of adolescents’ daily lives. However, the intensive use of social media can develop into a health-threatening addiction, but unfavourable health consequences can occur even with less use. Social media user groups categorized as no-risk, moderate risk (of developing problematic behaviour), and problematic use were examined with reference to their prevalence, their associations with individual determinants and health, and the increased health risk between groups. (2) Methods: The Finnish nationally representative HBSC data (persons aged 11, 13, and 15, n = 3408) and descriptive and binary logistic regression analysis were appl…

In recent years, social inequalities in food habits have been attracted particular governmental interest and several initiatives addressing the socioeconomic gradient in food habits have been highlighted. However, few internationally published studies have evaluated how trends in adolescents' food habits develop in the context of Nordic nutrition policy, or have compared differences bet…

LIITU 2018 -tutkimus : liikunnan merkitysten kirjo on kaventunut

Hieman reilu kolmasosa suomalaislapsista ja -nuorista liikkui suosituksen mukaan – toimintarajoitteita kokevista joka neljäs. Lasten ja nuorten liikunnalle antamien merkitysten kirjo oli kaventunut ja esteet vahvistuneet, vaikka koettu pätevyys ja liikuntamotivaatio olivat korkealla. Suurin osa lapsista ja nuorista kannatti urheilun eettisten sääntöjen noudattamista. Säännöllinen liikkuminen oli myönteisesti yhteydessä koettuun terveyteen. Säännöllisesti liikkuvilla oli myös vähemmän yksinäisyyden kokemuksia. nonPeerReviewed

Tyttöjen painonpudottaminen, painonhallintakeinot ja liikunta-aktiivisuus

Tutkimuksessa selvitettiin, kuinka yleisesti 13- ja 15-vuotiaat suomalaistytöt ilmoittavat pudottavansa painoaan, millaisena he kokevat painonsa ja millaisia painonhallintakeinoja he ilmoittavat käyttävänsä. Lisäksi tutkittiin, eroavatko aktiivisesti liikkuvat tytöt painoindeksin, painon kokemisen, painonpudottamisen tai painonhallintakeinojen suhteen vähemmän liikuntaa harrastavista. Tutkimuksen aineisto on koottu WHO-Koululaistutkimuksen vuoden 2002 kyselystä, jonka otos edustaa koko Suomen seitsemäs- (N = 853) ja yhdeksäsluokkalaisia (N = 875) tyttöjä.
