Reduced Immune Fitness and Job Performance
Reduced immune fitness can have a significant negative impact on work performance. The aim of the current study was to evaluate the impact of reduced immune fitness on job performance and associated costs for the Dutch economy. Data from n = 425 Dutch working adults (18-65 years old) who completed an online survey were analyzed to evaluate the number of days of absenteeism (not going to work) and presenteeism (working while sick) due to reduced i…
Mental Resilience, Mood, and Quality of Life in Young Adults with Self-Reported Impaired Wound Healing
The purpose of this study was to evaluate the impact of self-reported impaired wound healing on quality of life, wellbeing, and mood. It was hypothesized that individuals with impaired wound healing report significantly poorer mood compared to healthy controls. An online survey was conducted among 2173 Dutch young adults (18-30 years old) to investigate mood, neuroticism, and mental resilience. Participants were allocated to a healthy control gro…
Alcohol Consumption on the Heaviest Drinking Occasion and Hangovers during the First Dutch Covid-19 Lockdown
The purpose of this study was to compare alcohol consumption between the heaviest drinking occasion in the period before the coronavirus disease 2019 (COVID-19) lockdown (15 January-14 March 2020) and the first COVID-19 lockdown period (15 March-11 May 2020) in the Netherlands, including the presence and severity of associated hangovers. The analysis included a sub-sample from the "Corona Lockdown: how fit are you?" (CLOFIT) study, comprising N =…
Immune Fitness and the Psychosocial and Health Consequences of the Covid-19 Pandemic Lockdown in The Netherlands
This article provides an overview of the design and methodology of the “Corona lockdown: how fit are you?” (CLOFIT) study, including the questionnaires and scales that were included in the online survey. The aim of the CLOFIT study was to investigate the psychosocial and health consequences of the coronavirus disease 2019 (COVID-19) pandemic in the Netherlands. The survey was conducted among the Dutch population to collect data on immune fitness …
The Use of Single-Item Ratings Versus Traditional Multiple-Item Questionnaires to Assess Mood and Health
Collecting real-world evidence via ‘at home’ assessments in ambulatory patients or healthy volunteers is becoming increasingly important, both for research purposes and in clinical practice. However, given the mobile technology that is frequently used for these assessments, concise assessments are preferred. The current study compared single-item ratings with multiple-item subscale scores of the same construct, by calculating the corresponding Bl…
Covid-19 Lockdown-Related Changes in Mood, Health and Academic Functioning
The COVID-19 pandemic lockdowns were accompanied by an abrupt transition from face-to-face education to online education. The aim of this study was to evaluate the impact of the COVID-19 pandemic on academic functioning and mood in Dutch pharmacy students and PhD candidates. A total of n = 341 participants completed an online survey including questions on mood and academic functioning, assessed retrospectively for before and during the COVID-19 p…
Mood and Changes in Alcohol Consumption in Young Adults during Covid-19 Lockdown
The aim of this study was to explore the effects of the 2019 Coronavirus (COVID-19) lockdown on mood states, stress, alcohol consumption and perceived immune fitness in a Dutch sample. Analysis included a subsample from the "Corona Lockdown: how fit are you?" (CLOFIT) study, comprising N = 761 participants who reported consuming alcohol in 2020. Results show that, compared to pre-lockdown, the first COVID-19 lockdown (March 2020) was associated w…
Perceived Immune Fitness, Individual Strength and Hangover Severity
Various factors may contribute to alcohol hangover severity. The purpose of the current investigation was to evaluate the possible impact of alcohol consumption patterns, perceived immune status, and baseline fatigue on hangover severity. A survey was completed by a convenience sample of N = 199 Dutch students who reported on their latest past month's heavy drinking occasion, including subjective intoxication (perceived drunkenness) and next-day …
The Association between Ethanol Elimination Rate and Hangover Severity
Assessments in blood and saliva suggests that the amount of ethanol present in the first hours after alcohol consumption and into the following morning is associated with hangover severity. The current analysis determines how ethanol elimination rate is related to hangover severity reported throughout the day. n = 8 subjects participated in two studies. The first was a naturalistic study comprising an evening of alcohol consumption. Hangover seve…
Development and Validation of the Immune Status Questionnaire (ISQ)
The self-assessment of perceived immune status is important, as this subjective observation leads individuals to decide whether or not to seek medical help or adapt their lifestyle. In addition, it can be used in clinical settings and research. The aim of this series of studies was to develop and validate a short questionnaire to assess perceived immune functioning. Five surveys were conducted among Dutch and International young healthy adults (1…
Susceptibility to Alcohol Hangovers
Increasing evidence points at a role for the immune system in the genesis of the alcohol hangover. This study investigated the association between self-reported immune function and experiencing hangovers. Dutch students aged 18 to 30 years old were invited to complete an online survey. Eighteen items on immune-related complaints were completed to assess self-reported immune function. Alcohol consumption in the past month (with respect to usual co…
Differential Gender Effects in the Relationship between Perceived Immune Functioning and Autistic Traits
Altered immune functioning has been demonstrated in individuals with autism spectrum disorder (ASD). The current study explores the relationship between perceived immune functioning and experiencing ASD traits in healthy young adults. N = 410 students from Utrecht University completed a survey on immune functioning and autistic traits. In addition to a 1-item perceived immune functioning rating, the Immune Function Questionnaire (IFQ) was complet…
Dose-dependent cholesterol-lowering effects of phytosterol/phytostanol-enriched margarine in statin users and statin non-users under free-living conditions
Objective To assess the effectiveness (extent to which an intervention works in daily medical practice) of the use of phytosterol/phytostanol-enriched margarines to lower total and non-HDL cholesterol levels in users and non-users of statins. Design Retrospective cohort study. Setting Data were obtained from questionnaires on health and food intake from a population-based longitudinal cohort linked to pharmacy-dispensing records. Subjects The ana…
Years of temperature-related excess mortality in the Netherlands
Even in present-day high-income countries, there is a lot of evidence of a high degree of vulnerability of the population to both high and low outdoor temperatures. The magnitude of temperature-related mortality is strongly related to a wide variety of
Fertility of Turkish and Moroccan women in the Netherlands
The annual figures on the fertility of Turkish and Moroccan women show that the sharp decline that took place up to the mid nineties was reduced or stagnated. In this paper we use cohort data by generation for the main population groups of non-western
Socioeconomic inequalities in mortality within ethnic groups in the Netherlands, 1995–2000
Study objective: To analyse socioeconomic inequalities in mortality in Dutch, Turkish, Moroccans, Surinamese, and Antillean/Aruban men and women living in the Netherlands and to assess the contribution of specific causes of death to these inequalities. Design: Open cohort design using data from the Municipal Population Registers and cause of death registry. Setting: the Netherlands from 1995 through 2000. Participants: All inhabitants of the Neth…
Perinatal mortality in the Netherlands. Backgrounds of a worsening international ranking
