Introduction: Musculoskeletal injuries (MSIs) have direct impact on occupational readiness and task performance in military populations. Until this date, no epidemiologic data have been published concerning MSI incidence in the Netherlands Armed Forces (NAF). The aim of this study was to assess the MSI incidence and related costs in the NAF.

Background: In adults, overweight is associated with reduced lung function, in children evidence on this association is conflicting. We examined the association of body mass index (BMI) and waist circumference (WC) at age 12, and of persistently (at ages 8 and 12 years) high BMI and large WC, with forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) at age 12.

Methods: Height, weight, WC and FVC and FEV1 were measured during a medical examination in 1288 12-year-olds participating in the PIAMA birth cohort study.

Objective: To prospectively study the association of night and shift work with weight change and lifestyle behaviors.

Methods: Workers participating in the Netherlands Working Conditions Cohort Study (2008 and 2009) (N = 5951) reported night and shift work, weight and height. Groups included stable night or shift work, from day work to night or shift work, from night or shift work to day work, and no night or shift work in 2008 and 2009.

Purpose: To systematically summarise the literature on the effects of interventions for ageing workers that address work-related measures of sustainable employability, i.e. (early) retirement, work ability and work productivity.

Background: Several experimental studies showed consistent evidence for decreased energy expenditure at higher ambient temperatures. Based on this, an association between thermal exposure and body weight may be expected. However, the effect of thermal exposure on body weight has hardly been studied.

We investigated associations of time in bed and multiple sleep quality characteristics with cardiometabolic markers in children. Data from the prevention and incidence of asthma and mite allergy study, a population-based prospective birth-cohort study started in 1996-1997 in the Netherlands, were analysed. In total 1481 children aged 11-12 years completed a questionnaire (including questions on sleep) and underwent a medical examination.

Objective: Childhood and adolescent overweight, defined by body mass index (BMI) are associated with an increased risk of cardiovascular disease in later life. Abdominal adiposity may be more important in associations with cardiovascular diseases but waist circumference (WC) has been rarely studied in children. We studied associations between BMI and WC and blood pressure (BP) and cholesterol in 12-year-old children and prospectively changes in BMI or WC status between age 8 and 12 years and BP and cholesterol at age 12.

Background: Body mass index (BMI) and waist circumference (WC) may be associated with lung function in children, as observed in adults.

Methods: Height, weight, waist circumference, and lung function (FVC and FEV1 ) were measured during a medical examination in 1,058 eight-year-old children participating in the Prevention and Incidence of Asthma and Mite Allergy (PIAMA) birth cohort study.

Results: After adjusting for height, age and other potential confounders large WC or high BMI (>90th percentile) were not associated with forced expiratory volume in 1 sec (FEV1) or forced vital capacity (FVC).

Previous studies have suggested possible adverse side-effects of maternal use of folic acid-containing supplements (FACSs) during pregnancy on wheeze and asthma in early childhood. We investigated the association between maternal use of FACSs and childhood respiratory health and atopy in the first 8 yrs of life. Data on maternal use of FACSs, collected during pregnancy, were available for 3,786 children participating in the Prevention and Incidence of Asthma and Mite Allergy birth cohort study.

Background: Adult cholesterol concentrations might be influenced by early-life factors, such as breastfeeding and birth weight, referred to as "early programming". How such early factors exert their influence over the life course is still poorly understood. Evidence from studies in children and adolescents is scarce and conflicting.

Objective: Most epidemiological, questionnaire-based studies collect data on body weight and height but not on waist circumference (WC), although WC is suggested to be clinically more relevant. It is unknown whether valid WC data of school-aged children can be obtained by questionnaires. In this study the agreement between parental reported and measured WC in 8-year-old children was investigated and compared with the agreement between parental reported and measured body mass index (BMI).
