Adolescent Self-Reported Health in Relation to School Factors: A Multilevel Analysis.

Karina Nygren; Erik Bergström; Urban Janlert; Lennart Nygren

The aim of the study was to examine school-related determinants of self-reported health among adolescents. Questionnaire survey data comprising 4,972 students, Grades 7 through 9, from 20 schools in northern Sweden were used. Also, complimentary data about each school were collected from the Swedish National Agency for Education. Using multilevel logistic regression analyses, results showed that most variation in self-reported health was explained by individual-level differences. Truancy, bullying, and poor relations with teachers significantly increased the odds ratio of reporting poor general health, for boys and for girls. Most variables at the school level, for example, school size and student–teacher ratio, did not render significant associations with students’ self-reported health. In conclusion, this study indicates that health promotion at school, including school health services, may benefit from focusing primarily on individual-level determinants of health, that is, students’ relations to peers and teachers, without ignoring that bullying and weak student–teacher relationships also may induce school-level interventions.

Parents matter – but relations to parents do not explain gender differences in self‐reported health in adolescents

Karina Nygren; Erik Bergström; Urban Janlert; Lennart Nygren

The aim of the study was to explore whether parent-adolescent relations are associated to self-reported health of adolescents. Logistic regression analyses were performed on a cross-sectional data set consisting of 5060 adolescents, grades 7-9, from six municipalities in the northern part of Sweden. The study was approved by the Regional Ethical Review Board in Umeå, Sweden. Results showed that, in both boys and girls, experiencing low parental demands as well as perceiving the relationship quality and the communication with parents as poor were significantly associated with having poor general health, somatic complaints and feelings of stress. In general, girls scored lower on self-reported health than boys, but our findings indicate that these gender differences could not be explained by relations to parents. In conclusion, relations to parents play an important role for self-reported health of adolescents. Although no causal-effect statements can be determined in this study, it is implied that there is a need for health professionals, such as school nurses, school welfare officers, etc., to pay special attention to parent-adolescent relations in their work with adolescents.

Norm compliance and self-reported health among Swedish adolescents

Karina Nygren; Urban Janlert; Lennart Nygren

Aims: This study examines the relationship between norm compliance and self-reported health in adolescents, and how this differs between genders. Our specific aim was to investigate if extremely high norm compliance revealed any particular health patterns. Methods: This empirical study used a web-based survey from 2005, which was distributed to all students (n = 5,066) in years 7—9 of compulsory school within six municipalities in northern Sweden. The respondents answered questions about their general health as well as specific health problems such as headaches, stomach ache, sleeping difficulties and stress. Compliance was measured according to different norm-related behaviour, such as truancy, crime and use of tobacco, alcohol and narcotics. Results: The majority of respondents reported good health and norm-compliant behaviour. Girls reported more health problems than boys, a difference that increased with age. Those who were more norm compliant reported better health, fewer somatic complaints and less stress, which goes against our initial hypothesis that extremely high norm compliance and self-reported ill-health are related. There seemed to be a stronger relationship between self-reported health and norm compliance for girls than boys, in absolute terms. Conclusions: The results clearly show a relationship between norm compliance and health, and suggest inequalities between genders.

Is hypertension in adult age related to unemployment at a young age? : Results from the Northern Swedish Cohort

Karina Nygren; Weidan Gong; Anne Hammarström

Aim: The aim of this study was to analyse the relationship between early unemployment (ages 16–21 years) and adult hypertension after controlling for earlier hypertension, unemployment in adult life, risk factors for hypertension and confounders. Methods: A cohort of 927 (86.6% of the original cohort) 9th grade school-leavers was followed from 1981 until 2008. Data were collected through questionnaires, health examinations, and national registers. Univariate and multivariate logistic regression were used as primary statistical methods. Results: At ages 21 and 43, hypertension was significantly more prevalent among men than women (p < .001). Unemployment between the ages of 16 and 21 was related to hypertension at age 43 among women but not men. The odds ratio (OR) was persistently high (OR 3.16 [95% confidence interval 1.45–6.89]) after controlling for late unemployment, hypertension at age 16, risk factors for hypertension and confounders. There was no significant relationship between exposure to early unemployment and hypertension at age 21 for women or men. Conclusions: From a public health perspective, youth unemployment is a societal problem in need of more attention and intervention in order to prevent long-term adverse health outcomes.

Self-reported school demands and psychosomatic problems among adolescents – changes in the association between 1988 and 2011?:

Karina Nygren; Curt Hagquist

Aims: The aim of the present study was to examine changes over time in the relationship between self-reported school demands and psychosomatic problems, also considering the impact of student influence and teacher support. Methods: Data from a cross-sectional study (Young in Värmland) including eight data collections (1988–2011) among Swedish students aged 15–16 were used (n = 20,115). Analyses with multinomial logistic regression and descriptive statistics were applied. Results: Between 1988 and 2011, the proportions of students with a higher degree of psychosomatic problems increased, as did the proportion of students experiencing school demands that were too high. Finer-level analyses based on stratification of student groups did not show any associations at the aggregated level between increases of school demands and psychosomatic problems. Similarly, individual level analyses showed that the strength of the association between school demands and psychosomatic problems was not affected by year of investigation. Conclusions: Changes in school demands over time could not explain the increasing trend in psychosomatic problems among adolescents. Since the relationship between school demands and psychosomatic problems is strong across time, there is, however, a continued need for school-based interventions. More studies are required to gain further understanding of adolescent mental health from a trend perspective.

What Happens With Local Survey Findings? A Study of how Adolescent School Surveys are Disseminated and Utilized in Swedish Schools

Karina Nygren; Urban Janlert; Lennart Nygren

This paper aimed at examining the barriers to and facilitators of disseminating and utilizing the results of a local Swedish school survey. Interviews with 21 school district managers/principals were performed. Results showed that dissemination and utilization of local survey data appeared as two interrelated processes. With those processes, various barriers and facilitators were mentioned. The barriers and facilitators were not merely the opposites of each other; instead they qualitatively differed from each other depending on what phase in the process the manager/principal referred to. The results also showed that the dissemination phase was both a prerequisite for and interwoven with the utilization phase, e.g. dissemination efforts were important for how the survey results were utilized.
