Well-being and environmental quality: Does pollution affect life satisfaction?

PURPOSE: We aimed to explore the effect of ambient air pollution on individual persons' levels of subjective well-being. Our research question was: to what extent is an individual's life satisfaction shaped by exposure to PM10? METHODS: We used regression models to analyse data on subjective well-being indicators from the last two waves of the European social survey (ESS) and detailed information on local levels of the air pollutant PM10. RESULTS: An increase in PM10 annual concentrations by 1 µg/m(3) was associated with a significant reduction in life satisfaction of .017 points on the ESS 10-point life satisfaction scale. CONCLUSIONS: Our findings suggest that even in cases of relatively low levels of PM10 air pollution (mean annual concentration of 8.3 ± 3.9 µg/m(3)), in addition to the effects on physical health, exposure negatively affects subjective assessments of well-being.

Estonian National Mental Health Study: Design and methods for a registry-linked longitudinal survey.

OBJECTIVES: The Estonian National Mental Health Study (EMHS) was conducted in 2021-2022 to provide population-wide data on mental health in the context of COVID-19 pandemic. The main objective of this paper is to describe the rationale, design, and methods of the EMHS and to evaluate the survey response. METHODS: Regionally representative stratified random sample of 20,000 persons aged 15 years and older was drawn from the Estonian Population Register for the study. Persons aged 18 years and older at the time of the sampling were enrolled into three survey waves where they were invited to complete an online or postal questionnaire about mental well-being and disorders, and behavioral, cognitive, and other risk factors. Persons younger than 18 years of age were invited to fill an anonymous online questionnaire starting from wave 2. To complement and validate survey data, data on socio-demographic, health-related, and environmental variables were collected from six national administrative databases and registries. Additionally, a subsample was enrolled into a validation study using ecological momentary assessment. RESULTS: In total, 5636 adults participated in the survey wave 1, 3751 in wave 2, and 4744 in wave 3. Adjusted response rates were 30.6%, 21.1%, and 27.6%, respectively. Women and older age groups were more likely to respond. Throughout the three survey waves, a considerable share of adult respondents screened positive for depression (27.6%, 25.1%, and 25.6% in waves 1, 2, and 3, respectively). Women and young adults aged 18 to 29 years had the highest prevalence of depression symptoms. CONCLUSIONS: The registry-linked longitudinal EMHS dataset comprises a rich and trustworthy data source to allow in-depth analysis of mental health outcomes and their correlates among the Estonian population. The study serves as an evidence base for planning mental health policies and prevention measures for possible future crises.

Relationship between low depressiveness and domain specific physical activity in women.

In this study we investigated how different domains of physical activity are associated with depressiveness among women, and how individual variables moderate this relationship. Participants were 956 women, and the data were collected by mail-out survey using the Global Physical Activity Questionnaire, Beck Depression Inventory, and International Personality Item Pool. Lower depressiveness was related to higher leisure time physical activity and to lower occupational physical activity. Income, health problems, level of neuroticism, and extraversion had strong effects on depressiveness, and mediated the link between the leisure and occupational activities and depression.

Comparative Analysis of Gut Microbiota in Centenarians and Young People: Impact of Eating Habits and Childhood Living Environment.

The composition of centenarians' gut microbiota has consistently been used as a model for healthy aging studies. However, there is an incomplete understanding of how childhood living conditions and eating habits affect the development and composition of gastrointestinal microbiota in centenarians with good cognitive functions. We compared the gut microbiota as well as the living and eating habits of the oldest-old group and the young people group. The richness and diversity of microbiota and the abundance of hereditary and environmental microbes were higher in people with longevity than young people. People with longevity ate more potatoes and cereal products. In their childhood, they had more exposure to farm animals and did not have sewers compared with young people. Young people's gut microbiota contained more butyrate-producing bacteria and bacteria that characterized an animal-based Western diet. These results expand our understanding of the effects of childhood environment and diet on the development and stability of the microbiota in people with longevity.

The prevalence and patterns of exposure to interpersonal violence among men and women in Estonia.

BACKGROUND: To understand better the total burden of interpersonal violence on society, it is useful to assess the prevalence of interpersonal violence among both, men and women. Exposure to multiple forms of interpersonal violence, referred to as polyvictimization, has been associated with more severe health consequences than exposure to any form separately. The aims of this study were to assess the prevalence of emotional, physical and sexual interpersonal violence in childhood, adulthood and at both childhood and adulthood among men and women in Estonia, analyze the patterns of interpersonal violence and socio-demographic correlates of polyvictimization in adulthood by gender. METHODS: The analysis was based on two population-based, cross-sectional, self-administered surveys carried out among men and women in Estonia in 2014. In both surveys, the NorVold Abuse questionnaire was used to measure exposure to interpersonal violence. Men and women aged 18-44 were included to the analysis. RESULTS: Among men 66.6% and among women 54.2% had been exposed to at least one form of interpersonal violence during lifetime. Men had been more often exposed to isolated physical interpersonal violence, among women the distribution of different forms of interpersonal violence was more even and exposure to sexual violence was more common. The prevalence of polyvictimization in adulthood was two times higher among women compared to men and more socio-demographic correlates, were associated with it. Exposure to violence in childhood was associated with polyvictimization in adulthood across gender. CONCLUSIONS: The prevalence of interpersonal violence in Estonia is high among men and women. The most prevalent forms and patterns of interpersonal violence, however, differ by gender, as do the socio-demographic correlates. Screening for interpersonal violence, in childhood and adulthood, and gender-specific interventions are needed, especially for high-risk groups identified in this study. Primary prevention of childhood violence should be a priority, as it was associated with higher risk for exposure to violence later in life across gender.

Vulnerable adolescent participants' experience in surveys on sexuality and sexual abuse: ethical aspects.

OBJECTIVE: The aim of this research was to study the discomfort experienced by adolescents when answering questions in a survey about sexuality and sexual abuse and to investigate factors that may determine possible experience of discomfort. The research focused particularly on vulnerable adolescents-sexually abused and sexually inexperienced. METHOD: Adolescents in their final year of high school in Estonia (n=1,334) and Sweden (n=3,401) who had completed a survey about experiences of sexuality and sexual abuse answered additional questions about experiences of discomfort related to the survey questions. RESULTS: A majority of the participants did not feel discomfort when completing the survey. This was also the case for the two vulnerable groups. Experience of penetrating sexual abuse, sexual inexperience, mental health problems, rape myth acceptance, gender, immigrant background, and country were included in a structural equation model. Experience of penetrating sexual abuse was not significantly related to discomfort in the final model, while sexual inexperience was associated with increased discomfort (standardized coefficient .20) and rape myth acceptance was the strongest indicator of discomfort (.27). The total amount of explained variance was 17%. CONCLUSIONS: Our data do not support the view that adolescents in general or vulnerable subgroups such as sexually abused or sexually inexperienced adolescents experience discomfort when answering a survey about sexuality and sexual abuse. As discomfort ratings were not highly related to any of the predictors further research is needed that includes other factors. It is important to follow existing ethical guidelines since there may always be some individuals who feel discomfort.
