Seasonal variation of diet quality in a large middle-aged and elderly Dutch population-based cohort

PURPOSE: Several studies have reported seasonal variation in intake of food groups and certain nutrients. However, whether this could lead to a seasonal pattern of diet quality has not been addressed. We aimed to describe the seasonality of diet quality, and to examine the contribution of the food groups included in the dietary guidelines to this seasonality.METHODS: Among 9701 middle-aged and elderly participants of the Rotterdam Study, a prospective population-based cohort, diet was assessed using food-frequency questionnaires (FFQ). Diet quality was measured as adherence to the Dutch dietary guidelines, and expressed in a diet quality score ranging from 0 to 14 points. The seasonality of diet quality and of the food group intake was examined using cosinor linear mixed models. Models were adjusted for sex, age, cohort, energy intake, physical activity, body mass index, comorbidities, and education.RESULTS: Diet quality had a seasonal pattern with a winter-peak (seasonal variation = 0.10 points, December-peak) especially among participants who were men, obese and of high socio-economic level. This pattern was mostly explained by the seasonal variation in the intake of legumes (seasonal variation = 3.52 g/day, December-peak), nuts (seasonal variation = 0.78 g/day, January-peak), sugar-containing beverages (seasonal variation = 12.96 milliliters/day, June-peak), and dairy (seasonal variation = 17.52 g/day, June-peak).CONCLUSIONS: Diet quality varies seasonally with heterogeneous seasonality of food groups counteractively contributing to the seasonal pattern in diet quality. This seasonality should be considered in future research on dietary behavior. Also, season-specific recommendations and policies are required to improve diet quality throughout the year.

The diuretic action of weak and strong alcoholic beverages in elderly men

With ageing, there is a greater risk of dehydration. This study investigated the diuretic effect of alcoholic beverages varying in alcohol concentration in elderly men. Three alcoholic beverages (beer (AB), wine (AW), and spirits (S)) and their non-alcoholic counterparts (non-alcoholic beer (NAB), non-alcoholic wine (NAW), and water (W)) were tested in a diet-controlled randomized crossover trial. For the alcoholic beverages, alcohol intake equaled a moderate amount of 30 g. An equal volume of beverage was given for the non-alcoholic counterpart. After consumption, the urine output was collected every hour for 4 h and the total 24 h urine output was measured. AW and S resulted in a higher cumulative urine output compared to NAW and W during the first 4 h (effect size: 0.25 mL p < 0.003, effect size: 0.18 mL, p < 0.001, respectively), but not after the 24h urine collection (p > 0.40, p > 0.10). AB and NAB did not differ at any time point (effect size: -0.02 mL p > 0.70). For urine osmolality, and the sodium and potassium concentration, the findings were in line. In conclusion, only moderate amounts of stronger alcoholic beverages, such as wine and spirits, resulted in a short and small diuretic effect in elderly men.

Population differences in completeness and reliability of Dutch COVID-19 registry data

During the COVID-19 pandemic, the bidirectional relationship between policy and data reliability has been a challenge for researchers of the local municipal health services. Policy decisions on population specific test locations and selective registration of negative test results led to population differences in data quality. This hampered the calculation of reliable population specific infection rates needed to develop proper data driven public health policy. https://doi.org/10.1007/s12508-023-00377-y

The role of the dietitian in the management of malnutrition in the elderly

Aim: The prevalence of age‐related malnutrition is increasing in almost all Western countries. Because of their expertise, dietitians should have a central role in the management of malnutrition. This review aimed to synthesise the literature on the role of the dietitian in the management of malnutrition in the elderly in comparison with other health professionals. Methods: In November 2018, a search of Embase, Medline Ovid, Cinahl Ebscohost, Cochrane Central, Web of Science and Google Scholar was undertaken using ‘dietitian’, ‘elderly’ and ‘malnutrition’ as the main search terms. Qualitative and quantitative empirical research studies that focussed on the role of dietitians as the (main) subject of the study were included. Data extraction and data synthesis were performed by the three authors using a thematic synthesis approach. Results: Three themes emerged from the coding and synthesis of the 21 included studies. The first theme demonstrates that other health professionals' time for, and knowledge of, screening policies negatively affects the role of the dietitian. The second theme demonstrates that the importance of nutritional care is acknowledged. However, this does not always imply familiarity with dietetics nor does it always mean that other health professionals think involving dietitians is worth the effort. The third theme demonstrates that issues of workload appeared to be especially important in crossing or guarding role boundaries. Conclusions: The role of dietitians in managing age‐related malnutrition is not always clear and coherent. Therefore, how dietitians shape their role to provide optimal management of malnutrition in the elderly is open to debate. https://doi.org/10.1111/1747-0080.12546 LinkedIn: https://www.linkedin.com/in/matthijs-fleurke-66279110/ https://www.linkedin.com/in/dorien-voskuil-9b27b115/

The Role of the Social Network in Access to Psychosocial Services for Migrant Elderly

Background: Despite high prevalence of mental problems among elderly migrants in The Netherlands, the use of psychosocial care services by this group is low. Scientific evidence points at the crucial role of social support for mental health and the use of psychosocial services. We therefore explored the role of social networks in the access to psychosocial care among elderly migrants in The Netherlands. Methods: A qualitative study was conducted using semi-structured group interviews and individual interviews. The eight group and eleven individual interviews (respectively n = 58 and n = 11) were conducted in The Netherlands with Turkish, Moroccan, Surinamese, and Dutch elderly. The data were analysed through coding and comparing fragments and recognizing patterns. Results: Support of the social network is important to navigate to psychosocial care and is most frequently provided by children. However, the social network of elderly migrants is generally not able to meet the needs of the elderly. This is mostly due to poor mental health literacy of the social network, taboo, and stigma around mental illness and the busy lives of the social network members. Conclusions: Strategies to address help-seeking barriers should consider mental health literacy in elderly migrants as well as their social networks, and counteract taboos and stigma of mental health problems.
