Stability of morningness/eveningness and changes in sleep and mental health during mid-adulthood.

: A change toward Eveningness in circadian sleep-wake behavior is generally seen from childhood to adolescence, but less is known about circadian changes during adulthood. Circadian changes during mid-adulthood are of high interest, since Eveningness associates with a range of health-related problems, including psychological symptoms and mental disorders. In this study, we examined the circadian stability across 10 years, from 42 to 52 years of age, and how it is associated with sleep and mental health in a Finnish general population cohort follow-up-based ( = 976).

Life-Course Associations Between Smoking and Depressive Symptoms. A 30-Year Finnish Follow-up Study.

Introduction: Relatively little is known about whether the association between smoking and depressive symptoms changes with age and how the trajectories of smoking and depressive symptoms are intertwined during the life course. In this population-based study, these associations were examined from young adulthood to middle age.

Methods: Participants of a Finnish cohort study (N = 1955) were assessed at the ages of 22, 32, 42, and 52 using questionnaires covering daily smoking (yes/no) and the short 13-item Beck Depression Inventory.

Development of Body Dissatisfaction in Women and Men at Different Educational Levels During the Life Course.

Background: Our study examines the rarely investigated associations between body dissatisfaction and educational level over the life course in women and men.

Methods: A Finnish cohort (N = 1955) was followed by questionnaires at ages 22, 32, 42, and 52. Body dissatisfaction was measured by asking the respondents to evaluate their appearance using five response options.

Stress-induced eating and drinking and their associations with weight among women and men during 30-year follow-up.

Background: Stress is associated with obesity through several mechanisms, including coping methods used in stressful situations. However, long-term prospective studies investigating stress-induced eating and drinking in parallel and their relationships with weight are scarce.

Purpose: We examined the prevalence of stress-induced eating and drinking and their associations with body mass index (BMI) among women and men during a 30-year follow-up, as well as BMI trajectories from early adulthood to middle age.

Risk factors in adolescence as predictors of trajectories of somatic symptoms over 27 years.

Background: Somatic symptoms among adolescents are common, yet little is known about long-term trajectories of somatic symptoms and the factors in adolescence that shape them. We examined individual, family and school-based factors at age 16 as predictors of trajectories of somatic symptoms over 27 years.

Methods: Participants from the Northern Swedish Cohort (n = 1001) responded to questions about individual factors (e.

Stress, development and mental health study, the follow-up study of Finnish TAM cohort from adolescence to midlife: cohort profile.

Purpose: This cohort profile describes the Stress, development and mental health study (TAM), which is a cohort study investigating risk and protective factors as well as longitudinal associations regarding mental health and well-being from adolescence to midlife. This interdisciplinary cohort study operates, for example, in the fields of public health, social medicine, psychiatry and the life course perspective.

Participants: In 1981 (n=2242, 98.

Associations between relationship status and mental well-being in different life phases from young to middle adulthood.

The aim of this study was to assess the associations between relationship status and mental well-being in four different phases during the life course, and to identify whether relationship quality moderated these associations. We used a broader concept of relationship status (instead of marital status) and also included the positive dimension of mental health. Participants in a Finnish cohort study were followed up at ages 22 (N = 1,656), 32 (N = 1,471), 42 (N = 1,334), and 52 (N = 1,159).

The contribution of drinking culture at comprehensive school to heavy episodic drinking from adolescence to midlife.

Background: The school context is associated with adolescent alcohol use, but it is not clear whether this association continues into adulthood. This study examined whether exposure to drunkenness oriented drinking culture in 9th grade school class is associated with individuals' heavy episodic drinking (HED) from adolescence to midlife.

Methods: Participants in the 'Northern Swedish Cohort' study aged 16 years in 1981 were followed-up when aged 18, 21, 30 and 43 (N = 1080).

Poor peer relations in adolescence, social support in early adulthood, and depressive symptoms in later adulthood-evaluating mediation and interaction using four-way decomposition analysis.

Purpose: Supportive social relations are associated with good mental health, yet few studies have considered the prospective importance of adolescent peer relations for adult mental health and the potential mechanisms involved.

Methods: Participants (n = 941) were sourced from the Northern Swedish Cohort, a prospective study comprising school students aged 16 years in 1981. Integrating life course epidemiology with four-way decomposition analysis, this paper considers the controlled direct effect of poor peer relations at age 16 years on depressive symptoms at age 43 years, the pure indirect effect mediated by the availability of social support at age 30 years, and potential interactions between the exposure and the mediator.

Group activity participation at age 21 and depressive symptoms during boom and recession in Sweden: a 20-year follow-up.

Background: Organized group activities (e.g. sports or arts clubs) have long been noted as important developmental settings for youth, yet previous studies on the relationships between participation and mental health outcomes have focused on short-term effects among school-aged adolescents.

Social relationships in adolescence and heavy episodic drinking from youth to midlife in Finland and Sweden - examining the role of individual, contextual and temporal factors.

Background: Applying the Process-Person-Context-Time (PPCT) model of the bioecological theory, this study considers whether proximal processes between the individual and the microsystem (social relationships within family, peer group and school) during adolescence are associated with heavy episodic drinking (HED), from youth to midlife, and whether the macro level context (country) plays a role in these associations.

Methods: Participants of two prospective cohort studies from Finland and Sweden, recruited in 1983/1981 at age 16 (n = 2194/1080), were followed-up until their forties using postal questionnaires. Logistic regression analysis was used to examine associations between social relationships at age 16 and HED (at least monthly intoxication or having six or more units of alcohol in one occasion) at ages 22/21, 32/30 and 42/43.

Longitudinal prospective associations between psychological symptoms and heavy episodic drinking from adolescence to midlife.

Aim: This study examined whether development of psychological symptoms (PS) differed between persons with different longitudinal profiles of heavy episodic drinking (HED) from adolescence to midlife. In addition, the reciprocal associations between PS and HED were studied.

Methods: Participants of a Finnish cohort study in 1983 at age 16 ( N = 2194) were followed up at ages 22 ( N = 1656), 32 ( N = 1471), and 42 ( N = 1334).

Associations between unemployment and heavy episodic drinking from adolescence to midlife in Sweden and Finland.

Background: Unemployment and alcohol use have often been found to correlate and to act as risk factors for each other. However, only few studies have examined these associations at longitudinal settings extending over several life phases. Moreover, previous studies have mostly used total consumption or medical diagnoses as the indicator, whereas subclinical measures of harmful alcohol use, such as heavy episodic drinking (HED), have been used rarely.

Pathways from problems in adolescent family relationships to midlife mental health via early adulthood disadvantages - a 26-year longitudinal study.

Poor childhood family conditions have a long-term effect on adult mental health, but the mechanisms behind this association are unclear. Our aim was to study the pathways from problematic family relationships in adolescence to midlife psychological distress via disadvantages in early adulthood. Participants of a Finnish cohort study at the age of 16 years old in 1983 were followed up at ages 22, 32 and 42 years old (N = 1334).

Interpersonal Conflicts and Development of Self-Esteem from Adolescence to Mid-Adulthood. A 26-Year Follow-Up.

This study investigated the association between interpersonal conflicts and the trajectory of self-esteem from adolescence to mid-adulthood. The directionality of effects between self-esteem and interpersonal conflicts was also studied. Participants of a Finnish cohort study in 1983 at age 16 (N = 2194) were followed up at ages 22 (N = 1656), 32 (N = 1471) and 42 (N = 1334) using postal questionnaires.

A 26-year follow-up study of heavy drinking trajectories from adolescence to mid-adulthood and adult disadvantage.

Aims: The aim of the study was to identify heavy drinking trajectories from age 16 to 42 years and to examine their associations with health, social, employment and economic disadvantage in mid-adulthood.

Methods: Finnish cohort study's participants who were 16 years old in 1983 were followed up at age 22, 32 and 42 (n = 1334). Heavy drinking was assessed at every study phase and based on these measurements trajectories of heavy drinking were identified.

Effects of media exposure on adolescents traumatized in a school shooting.

This study analyzes the impact of the media on adolescents traumatized in a school shooting. Participants were trauma-exposed students (n = 231) and comparison students (n = 526), aged 13-19 years. A questionnaire that included the Impact of Event Scale and a 36-item General Health Questionnaire was administered 4 months after the shooting.
