Correcting for non-ignorable missingness in smoking trends

2015

Data missing not at random (MNAR) is a major challenge in survey sampling. We propose an approach based on registry data to deal with non-ignorable missingness in health examination surveys. The approach relies on follow-up data available from administrative registers several years after the survey. For illustration we use data on smoking prevalence in Finnish National FINRISK study conducted in 1972-1997. The data consist of measured survey information including missingness indicators, register-based background information and register-based time-to-disease survival data. The parameters of missingness mechanism are estimable with these data although the original survey data are MNAR. The u…

Tobacco Use Documenting Policy and Its Association With Pupils’ Smoking and Their Perception of the Enforcement of School Smoking Bans in Finland

2014

Finnish national data sets on schools (N = 496) and pupils (N = 74,143; 14–16 years) were used to study whether a systematic documenting policy for the violations of school smoking bans was associated with pupils’ smoking and their perceptions on the enforcement of smoking bans. Attending a school with a systematic documenting policy was associated with perceptions that smoking is prohibited and restrictions monitored, with lower levels of smoking in the vicinity of the school during the school day, but not with smoking prevalence. Findings suggest that a consistent documenting policy could be an effective tool for reducing pupils’ smoking in schools.

On-Road Study of Fatigue Management Strategies in Long-Haul Truck Drivers

2014

The current study investigated what strategies long-haul truck drivers use to mitigate fatigue at the wheel. A group of 52 truck drivers participated in the study in which drivers’ fatigue at the wheel was measured by a well-validated self-rating scale (the Karolinska Sleepiness Scale) and the use of fatigue countermeasures by a diary for a period of two consecutive workweeks including day and night-time trips. Results showed that the drivers more frequently used fatigue countermeasures while fatigued at the wheel but most of these countermeasures, with the exception of caffeine, can be regarded as inefficient (e.g., opening a window). The results indicate that long-haul truck drivers resp…

Effect of concurrent resistance and sprint training on body composition and cardiometabolic health indicators in masters cyclists

2016

In older previously sedentary individuals endurance training imposes a more effective stimulus to enhance cardiometabolic health compared with resistance or sprint training. We examined the effect of replacing a portion of endurance training with combined resistance and/or sprint training and how this influences cardiometabolic health indicators in masters endurance cyclists. Twenty-seven well-trained male road cyclists (53.7± 8.2 years) were allocated to a resistance and track sprintcycling training group (RTC, n= 10), an endurance and track sprint-cycling group (ETC, n = 7) or a control endurance group (CTRL, n = 10). Both the RTC and ETC groups completed a 12-week intervention of specifi…

User-oriented evaluation of mechanical single-channel axial pipettes.

2013

Hand tools should be designed so that they are comfortable to use, fit the hand and are user-oriented. Six different manual, single-channel axial pipettes were evaluated for such objective outcomes as muscular activity, wrist postures and efficiency, as well as for subjective outcomes concerning self-assessed features of pipette usability and musculoskeletal strain. Ten experienced laboratory employees volunteered for the study. The results showed that light and short pipettes with better tool comfort resulted in reduced muscular activity and perceived musculoskeletal strain when they were compared with a long and heavy pipette. There were no differences in the efficiency between the differ…

Ergonomic Comparison of a Sit-Stand Workstation With a Traditional Workstation in Visual Display Unit Work

2013

Purpose: To compare ergonomics of an electrically adjustable sit-stand workstation with a traditional workstation in video display unit (VDU) work. Methods: Twelve female workers (aged 27-53 years) participated in this experimental study. Electromyography, wrist postures, subjective assessments, and productivity were used to make the ergonomic comparison. Results: The muscle activity of the right trapezius (p=0.01) and left wrist extensors (p=0.02), extension of the right (p=0.05) and left (p=0.002) wrist, and perceived strain of the arms (p=0.05) were lower and productivity was better (p=0.02) when the workers used a low-sitting, high-sitting, or standing posture at the sit-stand workstati…

Physical Fitness in Young Men between 1975 and 2015 with a Focus on the Years 2005–2015

2018

Purpose: The purpose of the present study was to investigate changes in physical fitness and anthropometry of young men entering the military service in Finland during the years 1975–2015. Methods: The study included the fitness test results of 627,142 healthy young male conscripts (age 19.1 T 0.4 yr). Data included results of aerobic capacity, muscle fitness tests, and anthropometric characteristics. Results: The results show that the increase in mean body mass of young men has slowed down during the last 10 yr. However, the total increase in body mass was 6.8 kg (8.8%, P e 0.001) between 1993 and 2015. The mean distance achieved in the 12-min running test decreased by 337 m (12.2%, P e 0.…

Mental health promotion competencies in the health sector in Finland : a qualitative study of the views of professionals

2019

Aims: In this study, we aimed to investigate what competencies are needed for mental health promotion in health sector practice in Finland. Methods: A qualitative study was carried out to seek the views of mental health professionals regarding mental health promotion-related competencies. The data were collected via two focus groups and a questionnaire survey of professionals working in the health sector in Finland. The focus groups consisted of a total of 13 professionals. Further, 20 questionnaires were received from the questionnaire survey. The data were analysed using the qualitative data analysis software ATLAS.ti Scientific Software Development GmbH, Berlin. A content analysis was c…

Cognitive consequences of the timing of puberty

2018

In this paper, we use British cohort data to study the degree to which children at different stages of pubertal development at age 11 and 16 differ in their cognitive and behavioral outcomes at age 16 as well as in their completed educational attainment and adult earnings. Controlling for age 7 cognitive skills, region of birth, father's socioeconomic status and parents’ education, we show that boys’ late pubertal development is associated with lower levels of cognitive skills at 16, lower final educational attainment, and lower earnings in adulthood. For girls we find a similar negative relationship between late puberty and cognitive skills, but only imprecise relationships between the tim…
