Importance of physical health and health-behaviors in adolescence for risk of dropout from secondary education in young adulthood: an 8-year prospective study

Education and health constitute two interlinked assets that are highly important to individuals. In Iceland, prevalence of dropout from secondary education poses a considerable problem. This 8-year prospective study assesses to what extent poor physical health and negative health-behaviors of Icelandic adolescents predict increased odds of dropout from secondary education. The sample included n = 201 Icelandic children who participated at age 15 (baseline) and again at age 23 (follow-up). Data included objective measurements of physical health and questionnaires assessing health-behaviors, education status, parental education, neighborhood characteristics, self-esteem, and depression. Independent t-tests and chi-square were used to assess differences in physical health and health-behaviors at follow-up stratified by education status. Ordinal regression models were conducted to assess whether physical health and health-behaviors at age 15 predicted increased odds of dropout from secondary education at age 23, independent of gender, parental education and psychological factors. At age 23, 78 % of girls and 71 % of boys had completed a secondary education. Completion of a secondary education was associated with significant health benefits, especially among women. Women without a secondary education had lower fitness, more somatic complaints, higher diastolic blood pressure, less sports participation, and poorer sleep, whilst men without a secondary education watched more television. In logistic regression models somatic complaints during adolescence were associated with 1.09 (95 % CI: 1.02-1.18) higher odds of dropout from secondary education in young adulthood, independent of covariates. Health-behaviors associated with higher dropout odds included smoking (3.67, 95 % CI: 1.50-9.00), alcohol drinking (2.57, 95 % CI: 1.15-5.75), and time spent watching television (1.27, 95 % CI:1.03-1.56), which were independent of most covariates. Finally, mother's higher education was strongly associated with significantly lower dropout odds (OR 0.54, 95 % CI: 0.34-0.88) independent of father's education and psychological factors, whilst high self-esteem was independently associated with lower dropout odds (OR 0.91, 95 % CI: 0.85-0.98). Completion of a secondary education yields substantial physical health benefits for young women, but not for men. Importantly, somatic complaints and negative health-behaviors among adolescent boys and girls adversely impact their educational outcomes later in life, and may have widespread consequences for their future prospects.Peer Reviewe

Type D personality is associated with impaired psychological status and unhealthy lifestyle in Icelandic cardiac patients: a cross-sectional study.

To access publisher's full text version of this article. Please click on the hyperlink in Additional Links field.Type D (distressed) personality has been associated with adverse cardiac prognosis and poor emotional well-being in cardiac patients, but it is still unclear what mechanisms link Type D personality with poor clinical outcomes in cardiac patients. In the present cohort of Icelandic cardiac patients, we examined potential pathways that may explain this relationship. The objectives were to examine 1) the association between Type D personality and impaired psychological status, and to explore whether this association is independent of disease severity; and 2) the association between Type D personality and an unhealthy lifestyle. A sample of 268 Icelandic coronary angiography patients (74% males (N = 199); mean age 62.9 years (SD 10.5), range 28-85 years) completed the Type D Scale (DS14), Hospital Anxiety and Depression Scale (HADS), and Perceived Stress Scale (PSS) at hospitalization. Health-related behaviors were assessed 4 months following angiography. Clinical data were collected from medical files. Type D personality was associated with an increased risk of anxiety (OR 2.97, 95% CI:1.55-5.69), depression (OR 4.01, 95% CI:1.42-11.29), and stress (OR 5.99, 95% CI:3.08-11.63), independent of demographic variables and disease severity. Furthermore, fish consumption was lower among Type Ds, as 21% of Type Ds versus 5% of non-Type Ds consumed fish < 1 a week (p < 0.001). Type D patients were also more likely to smoke at follow-up (22% versus 10%, p = 0.024) and to use antidepressants (17% versus 9%, p = 0.049) and sleeping pills (49% versus 33%, p = 0.019) compared to non-Type Ds. Type D personality was not associated with other health-related behaviors, aside from trends towards less fruit and vegetable consumption, and more weight gain. Type D personality was associated with psychological distress and an unhealthy lifestyle in Icelandic cardiac patients. Future studies should further investigate the association between Type D personality and health-related behaviors.Rannis Icelandic Centre for Research (Reykjavik, Iceland) Landspitali-Hospital Research Found (Reykjavik, Iceland) Netherlands Organisation for Scientific Research (The Hague, The Netherlands) VICI 453-04-004 Landspitali-University Hospita

Different factors associate with body image in adolescence than in emerging adulthood: A gender comparison in a follow-up study

Background Body image dissatisfaction has been linked with a range of adverse psychosocial outcomes in both genders and has become an important public health issue. Across all ages, women have reported being more dissatisfied with their bodies than men. The aim of the current study was to examine if fitness and physical activity associate with body image satisfaction differently across gender and age, measured in the same participants. Participants and procedure Participants were measured initially at age 15 years (N = 385) and again at age 23 years (N = 201). Structural equation modelling was used to examine the association between body image satisfaction, fitness, and physical activity. Covariates included skinfold thickness, body mass index, socioeconomic status, anxiety, and depression. Results Fitness and physical activity declined during the study period, body mass index increased, but no changes were found in body image satisfaction, depression, anxiety, or skinfold thickness. For women at ages 15 and 23 years, self-reported fitness and depression were found to be related to body image satisfaction, including body mass index at the age of 23 years. For 15-year-old men, skinfold thickness and aerobic fitness related to body image satisfaction, whereas skinfold thickness, depression, body mass index, and self-reported fitness did so at age 23 years. Conclusions Results suggest that different approaches are needed across gender to improve body image in adolescence whereas more similar ones can be used in emerging adulthood.Background Body image dissatisfaction has been linked with a range of adverse psychosocial outcomes in both genders and has become an important public health issue.

Different cardiorespiratory fitness expressions based on the maximal cycle ergometer test show no effect on the relation of cardiorespiratory fitness to the academic achievement of nine-year-olds

The relationship between cardiorespiratory fitness and academic achievement has been inconclusive. The results may depend on how cardiorespiratory fitness is expressed. The aim of this study is to explore the impact of different cardiorespiratory fitness expression methods, measured by the maximal cycle ergometer test, on the relationship between cardiorespiratory fitness and academic achievement. A cross-sectional study consisting of 303 Icelandic 4th grade students (163 girls) was conducted. Cardiorespiratory fitness was assessed using a graded maximal cycle ergometer test and scores of standardized tests in Icelandic and math obtained from the Icelandic National Examination Institute. Cardiorespiratory fitness was measured as absolute power output in watts in a maximal progressive cycle ergometer test. To adjust for different body sizes, the power output was scaled to body weight, body height, body surface area, and allometrically expressed body weight. In addition, linear regression scaling was also used to adjust for different body sizes. No significant relationship was found between any of the cardiorespiratory fitness expressions and academic achievement, using both univariate and multivariate linear regression analyses. The use of different methods to express cardiorespiratory fitness does not significantly affect the association with the academic achievement of fourth grade students.The Icelandic Centre for Research (RANNIS) funded this study, along with the Ministry of Education, Science and Culture, and The Icelandic Primary Health Care Research Fund.

Organized leisure-time sport participation and academic achievement in preadolescents

Publisher's version (útgefin grein)Aims: The aims of this study were to study the correlation between lifestyle-related factors, such as organized leisure-time sport participation (OLSP), cardiorespiratory fitness, and adiposity, and academic achievement among preadolescents. Methods: A cross-sectional study involving 248 nine-year-old school children was carried out. OLSP was self-reported with parental assistance, categorized as ≤ 1× a week, 2–3× a week, and ≥ 4× times a week or more. Academic achievement was estimated with results from standardized test scores in Icelandic and math. Cardiorespiratory fitness was estimated using a maximal cycle ergometer test. The sum of four skinfolds was used to estimate adiposity. Results: Tests of between-subjects effect indicated that OLSP significantly correlated with achievement in math only (F(2,235) = 3.81, p = 0.024). Further analysis showed that the two less active groups had significantly lower scores in math compared to the most active group with OLSP ≥ 4× times a week or more (2–3× times a week, unstandardized coefficient (b) = –4.08, 95% confidence interval (CI) [–7.09, –1.07]; ≤ 1× a week, b = −3.84, 95% CI [–7.59, –0.08]), independent of sex, age, maturity level (age to/from peak height velocity), family structure, and parental education. Neither cardiorespiratory fitness nor adiposity significantly correlated with academic achievements. Conclusions: The study’s result indicates that frequent (four times per week or more often) sport participation is not harmful but may be beneficial to learning. However, further intervention-based study of this topic is needed to determine if this relationship is causal.The Icelandic Centre for Research (RANNIS) funded this, along with the Ministry of Education, Science and Culture, and The Icelandic Primary Health Care Research FundPeer Reviewe

Online writing about positive life experiences reduces depression and perceived stress reactivity in socially inhibited individuals

Therapeutic writing can enhance psychological and physical health. Recent studies have suggested that these kinds of interventions can be effective when delivered online. The present study investigated whether positive emotional writing online can influence psychological and physical health in individuals reporting high levels of negative affectivity, who are most likely to benefit from psychological intervention (N = 72, Mage = 28.5, SDage = 8.7), and further, to investigate the potential moderating role of social inhibition. Participants completed self-report measures of physical symptoms, perceived stress, perceived stress reactivity, depression and generalised anxiety, before completing either i) positive emotional writing, or ii) a non-emotive control writing task on an online portal, for 20 minutes per day over three consecutive days. State anxiety was measured immediately after each writing session, and self-report questionnaires were again administered four weeks post-writing. Socially inhibited individuals exhibited significant reductions in depression and perceived stress reactivity four weeks following positive emotional writing, relative to writing about a neutral topic. The present study supports the efficacy of online therapeutic writing in individuals who, due to their socially inhibited nature, are most likely to benefit from online interventions which avoid interaction with a therapist or other clients

Comparing methods for assessment of facial dynamics in patients with major neurocognitive disorders

International audienceAssessing facial dynamics in patients with major neurocogni-tive disorders and specifically with Alzheimers disease (AD) has shown to be highly challenging. Classically such assessment is performed by clinical staff, evaluating verbal and non-verbal language of AD-patients, since they have lost a substantial amount of their cognitive capacity, and hence communication ability. In addition, patients need to communicate important messages, such as discomfort or pain. Automated methods would support the current healthcare system by allowing for telemedicine, i.e., lesser costly and logistically inconvenient examination. In this work we compare methods for assessing facial dynamics such as talking, singing, neutral and smiling in AD-patients, captured during music mnemotherapy sessions. Specifically, we compare 3D Con-vNets, Very Deep Neural Network based Two-Stream ConvNets, as well as Improved Dense Trajectories. We have adapted these methods from prominent action recognition methods and our promising results suggest that the methods generalize well to the context of facial dynamics. The Two-Stream ConvNets in combination with ResNet-152 obtains the best performance on our dataset, capturing well even minor facial dynamics and has thus sparked high interest in the medical community

Validity of Type D personality in Iceland: association with disease severity and risk markers in cardiac patients

Type D personality has been associated with poor prognosis in cardiac patients. This study investigated the validity of the Type D construct in Iceland and its association with disease severity and health-related risk markers in cardiac patients. A sample of 1,452 cardiac patients completed the Type D scale (DS14), and a subgroup of 161 patients completed measurements for the five-factor model of personality, emotional control, anxiety, depression, stress and lifestyle factors. The Icelandic DS14 had good psychometric properties and its construct validity was confirmed. Prevalence of Type D was 26–29%, and assessment of Type D personality was not confounded by severity of underlying coronary artery disease. Regarding risk markers, Type D patients reported more psychopharmacological medication use and smoking, but frequency of previous mental problems was similar across groups. Type D is a valid personality construct in Iceland, and is associated with health-related risk markers, but not cardiac disease severity
