Hoe blijf je sterk op hogere leeftijd

Herken je het ook, bij je ouders, bij cliënten op werk of wellicht ook bij jezelf? Opstaan uit de stoel wordt moeilijker, traplopen gaat haast niet meer of de deksel van de jampot openmaken blijkt onmogelijk? Het goede nieuws is dat je met veel bewegen en goede voeding veel langer sterk kunt blijven

One-Year Results of the BeweegKuur Lifestyle Intervention Implemented in Dutch Primary Healthcare Settings

Background. Lifestyle interventions focusing on healthy diet and physical activity (PA) are effective in reducing health risks in controlled research settings. The aim of this study was to investigate the one-year results of the BeweegKuur lifestyle intervention implemented nationwide in Netherlands for people with a weight-related health risk. Materials and Methods. Data were requested from all 160 locations participating in the BeweegKuur. In a one group pretest/posttest study, one-year changes in health outcome variables and time spent on physical activity were tested with dependent t-tests. Associations between one-year changes in weight and waist circumference and sociodemographic factors and uptake of the program were analysed with ANOVA. Results. Data for 517 participants from 47 locations were available for analysis. One year after the intervention, weight reduced by 2.9 kg (95% CI −3.3;, −2.5), waist circumference by 4.3 cm (−4.9; −3.7), and blood glucose by 0.5 mmol/L (−0.8; −0.3). Physical activity increased significantly. Higher uptake of the program was associated with a larger decrease in waist circumference. Conclusion. The results of the study suggest that lifestyle interventions implemented in real-life primary healthcare settings with tailor-made supervision can contribute meaningfully to primary prevention

Occupational exposure to silica and lung cancer risk in the Netherlands

Objectives: The lung cancer carcinogenicity of crystalline silica dust remains the subject of discussion. Epidemiological evidence is based on occupational cohort studies and population-based case-control studies. The aim of this study was to assess associations between male lung cancer risk and silica exposure in a population-based cohort study. Methods: The study was conducted among men aged 55-69 years (n=58 279) from the Netherlands Cohort Study, which included self-reported, life-time job histories. Job titles were linked to the occupational groups of the external Finnish Job Exposure Matrix (FINJEM), including probability and level of silica exposure, each for specific time periods. 1667 incident lung cancer cases with known silica exposure status (210 exposed) were available after 11.3 years of follow-up. Risks were estimated based on a case-cohort design, and using Cox proportional hazards models. Results: Adjusted for smoking and other confounders, elevated risks were observed for exposure duration (RR 1.65, 95% CI 1.14 to 2.41 for 26-51 years vs no exposure) and cumulative exposure (RR 1.47, 95% CI 0.93 to 2.33 for ≥3 vs <3 mg/m³.year). Associations with average exposure levels were weaker. Associations were stronger for occupations with an exposure probability of ≥90%. Adjustment for asbestos exposure slightly increased the risk. Conclusions: Results from this prospective populationbased cohort study corroborate the classification of crystalline silica as a lung carcinogen. Associations could not be explained by smoking or by asbestos exposure

Exposure profiles of pesticides among greenhouse workers: implications for epidemiological studies.

Contains fulltext : 51497.pdf (publisher's version ) (Closed access)The aim of this study was to assess exposure to pesticides for a longitudinal epidemiological study on adverse reproduction effects among greenhouse workers. Detailed information on pesticide use among greenhouse workers was obtained on a monthly basis through self-administered questionnaires and subsequent workplace surveys. Questionnaires were filled in for a whole year. Dermal exposure rankings were developed for each task using the observational method Dermal Exposure Assessment Method (DREAM). Exposure scores were calculated for each worker for each month during the year, taking into account frequency, duration and exposure intensity for each task. A total number of 116 different active ingredients were used in the population, whereas a mean number of 15 active ingredients were applied per greenhouse. DREAM observations provided insight into the exposure intensity of 12 application techniques and three mixing and loading activities. Relatively high DREAM scores were obtained for scattering, fogging, dusting, and mixing and loading of powders. Observations with DREAM indicated that application with a horizontal ground-boom, motor driven boom, and bulb shower resulted in low dermal exposure. Exposure scores showed substantial variation between workers and over the year. It can be concluded that exposure variation between- and within greenhouses is very large, both in terms of chemical composition and exposure intensity. This may be a significant contributor to the inconsistent results of studies evaluating health effects of pesticide exposure
