Joint associations of leisure time physical activity and screen sitting time with long-term sickness absence due to mental and musculoskeletal diseases: a registry linked follow-up study.

OBJECTIVES: To examine joint associations of leisure-time physical activity (LTPA) and screen sitting time with subsequent sickness absence among the adult population. STUDY DESIGN: Registry linked follow-up study. METHODS: A representative sample of Finnish adults (n = 10,300) were asked to fill out a questionnaire for the FinHealth 2017 survey. Self-reported LTPA was classified into three groups: inactive, moderately active, and active, and screen sitting time into two groups: 3 h or less and over three hours a day, yielding a six-category variable for the joint analyses. Questionnaire data were linked to the Finnish Social Insurance Institution's register data on sickness benefits (over 9 days), including diagnoses (follow-up 2.9 years). The analytical samples were restricted to working age (18-64 years), which included 5098 participants. Associations were examined using logistic regression analysis adjusting for covariates with SPSS 29. RESULTS: The inactive and high sitting time had a higher risk for sickness absence due to mental disorders (OR 2.07, 95% CI 1.03-4.18) compared with the physically active, low-sitting time group. Additionally, the inactive and low sitting time (OR 1.69 95% CI 1.12-2.55) and the moderately active and high-sitting time groups (OR 2.06 95% CI 1.15-3.67) had a higher risk. No significant associations were found for all-cause and musculoskeletal diseases sickness absence. CONCLUSION: Employers and policymakers could support reducing sitting in front of a screen and increase LTPA outside working hours to prevent mental health problems and related sickness absences.

Tobacco use and dental fear among 15-16 year-old adolescents in Finland.

OBJECTIVE: The aim of this cross-sectional study was to evaluate the association between tobacco use and dental fear when adjusting for gender, parent's level of education and oral health habits. MATERIAL AND METHODS: This secondary analysis used questionnaire data from 15- and 16-year-old adolescents and their parents (n=2486). Ninety-four percent of the adolescents and 73% of the parents responded. For logistic regression analysis, variables were categorized as follows: dental fear (dependent) 0=not at all to somewhat afraid, 1=quite or very afraid; tobacco use (independent) 0=never, 1=occasionally or more often; and for confounders: tooth-brushing 0=at least twice a day, 1=once a day or less often; xylitol products 0=at least three times a day, 1=two times a day or less often; and parents' occupation: 0=both low, 1=high+low, and 2=both high. RESULTS: 2223 adolescents were included in the final analyses resulting in a 89% response rate. Those using tobacco at least occasionally were more likely to have dental fear than those who reported they had never used tobacco, also when adjusting for oral health habits, gender and parents' occupation (OR=1.74, 95% CI=1.31-2.33). CONCLUSIONS: Adolescent tobacco users were more likely to have dental fear than non-users. Dental teams should consider this when meeting adolescents who have dental fear and/or are using tobacco. The possible common vulnerability factors for dental fear and tobacco use needs further study.

Difficulties in emotional regulation: association with poorer oral health-related quality of life in the general population.

Personality is one of the strongest predictors of subjective well-being and may, according to a few previous studies, affect how people report oral health-related quality of life (OHRQoL). Alexithymia, a personality trait involving difficulties in emotional regulation, is associated with poorer health-related quality of life in the general population. We studied if alexithymia is also associated with poorer OHRQoL in a general population sample of 4,460 adults. Oral health-related quality of life was measured using the 14-item Oral Health Impact Profile (OHIP-14) and alexithymia was measured using the 20-item Toronto Alexithymia Scale (TAS-20). Controlling for clinically assessed dental health, depression, anxiety, and socio-demographic variables, higher scores on the TAS-20 as well as on its three dimensions [difficulties in identifying feelings (DIF), difficulties in describing feelings (DDF), and externally oriented thinking (EOT)] were associated with higher OHIP-14 composite scores according to Poisson regression analyses. In adjusted logistic regression analyses, the TAS-20 and two of its dimensions (DIF and DDF) were positively and significantly associated with the seven OHIP-14 dimensions and the prevalence of those reporting one or more OHIP-14 items fairly often or very often. The study showed that difficulties in emotional regulation might be reflected in poorer OHRQoL, regardless of the dental health status, depression, anxiety, and socio-demographic variables.

Polycyclic aromatic hydrocarbons in Finnish sauna air.

The concentrations of polycyclic aromatic hydrocarbons (PAH) in the air of three different types of wood-heated saunas were studied. The highest concentrations were found in the smoke sauna (total PAH 170-1550 micrograms/m3, benzo[a]pyrene 4.6-20 micrograms/m3) the second highest in the preheated sauna (total PAH 50-90 micrograms/m3, benzo[a]pyrene 3.4-4.5 micrograms/m3) and the lowest concentrations in the sauna heated by continuous burning of wood (total PAH 25 micrograms/m3, benzo[a]pyrene below 0.1 micrograms/m3). The results clearly indicate that regular bathing in the smoke sauna and in the pre-heated sauna increases the intake of PAH compounds (e.g. benzo[a]pyrene and benzo[a]anthracene).
