Hydration status plays a key role in healthy ageing, and it is potentially affected by several factors, including drug consumption. However, research on this issue to date is scarce, especially in highly vulnerable groups, such as the elderly. We aimed to study the relationship linking hydration status, analysed by means of a validated questionnaire, 24 h urine analysis, body composition assessment, and drug consumption in a sample of old adults. A total of 144 elders were included in the study. Cardiovascular drug consumption was significantly associated with a lower water intake in men (β = −0.282, p = 0.029). Moreover, urinary analysis revealed that total drug intake as well as the consumption of diuretics and cardiovascular drugs were associated with poorer hydration status, whereas genito-urinary drugs were associated with an opposite effect, and these results were confirmed in terms of body composition. Hence, total drug consumption (β = −0.205), diuretic (β = −0.408), cardiovascular (β = −0.297), and genito-urinary drugs (β = 0.298) were significantly associated (p < 0.05) with total body water. The obtained results confirmed the impact of chronic treatment with certain drugs on hydration status. Nutritional interventions may be of great interest in certain population groups in order to prevent complications due to altered hydration status. [ABSTRACT FROM AUTHOR]

Background: Childhood overweight and obesity is a global concern and has increased in Spain over the last decades. Combinations of lifestyle behaviors (i.e., diet, sleep, and sedentarism) are highly related to weight status. Therefore, this study aimed to identify lifestyle patterns among children from Madrid City, and analyze associations with the prevalence of overweight, obesity, and abdominal obesity, considering socio-economic factors. Methods: A cross-sectional analysis was conducted on 4545 children from the ENPIMAD study with data on diet, sleep, anthropometric, and socio-economic variables. K-means cluster analysis was used to identify lifestyle clusters, and logistic regressions were used to examine the associations between socio-economic indicators and cluster membership, and between clusters and weight status. Results: Findings show three lifestyle clusters (healthy, mixed, and unhealthy), with boys and older children more represented in the unhealthy cluster. Food insecurity and low socio-economic status were associated with unhealthier clusters in boys and girls. Children in unhealthier clusters were more likely to have obesity and abdominal obesity. However, these associations disappeared in girls after controlling for food insecurity. Conclusion: These results provide insight into the combination of behaviors and socioeconomic factors associated with childhood obesity that may aid in the design of future interventions.

Proteins are macronutrients with multiple health benefits, but excessive consumption can negatively affect health. This study aimed to evaluate the characteristics of a sample of high-protein processed foods (HPPFs), describe how their consumption affects dietary balance, and acquire knowledge of the consumption patterns of these products in a Spanish population. A sample of HPPFs available in supermarkets and on websites was collected. The contribution to recommended protein intakes was calculated using national and international references and considering the single consumption of the HPPFs and the product plus 150 g of meat. Furthermore, an online survey was conducted among a convenience sample. A total of 36 enriched protein products were evaluated. The percentage of proteins in these products ranges from 10 to 88%. The contribution of the protein recommended intake was within a range of 87.4–306.6% and 66.4–232.8% (women and men, respectively), only considering the additional proteins from 150 g of meat. One hundred thirty-nine participants completed the survey; 67.6% affirmed that they had consumed HPPFs, and half consumed them without following any consumption control. Since these products are accessible to everyone in supermarkets and protein intake is generally higher than the recommended limits, regulating the mass sale of HPPFs is essential to ensure they do not lead to protein overconsumption.

Introduction: Vitamin D is a key nutrient for health. Recent research has shown that it is not only necessary for the maintenance of bone health, but also for the prevention of cardiovascular diseases, insulin resistance, respiratory diseases, infections, and cancer, among others. Solar synthesis of vitamin D is usually insufficient, so it is necessary to provide enough vitamin D through the diet in order to maintain an adequate nutritional status. Studies carried out in Spain and other countries have shown that serum levels of the vitamin were usually insufficient and that average dietary intakes were well below those marked as recommended, while the main food sources of vitamin D were fatty fish, breakfast cereals, eggs, and dairy. Food sources of vitamin D are scarce, and it is naturally located in the fatty part of foods of animal origin, and in the liver and viscera. Fortifying foods that are not natural food sources of vitamin D but are regularly consumed by a significant percentage of the population, is a strategy that could help to increase vitamin D intake. In this regard, dairy products and breakfast cereals are two of the most widely used food matrices for vitamin D fortification, and their incorporation into the usual diet has proven to be an effective strategy to improve the nutritional situation of the population in vitamin D.

Childhood obesity is an important public health problem, also in Spain. The ALADINO study, in the context of the COSI strategy of the WHO European office, monitors the weight status of Spanish schoolchildren aged 6 to 9 years, and analyzes the associated factors. Data from the 2019 wave indicate that 23.3 % of schoolchildren are overweight, and 17.3 % are obese. A high percentage of schoolchildren eat breakfast regularly, although breakfast quality can be improved. The frequency of consumption of fruits and vegetables is low, even lower than that of other countries participating in the COSI strategy. In terms of lifestyle, more than 70 % of schoolchildren are active, although this percentage is lower than the European average. Screen exposure time is also shorter than in other countries, but this habit may be improved in a high percentage of schoolchildren. There is a lower percentage of schoolchildren with obesity who have breakfast or are active compared to those of normal weight, while they are more sedentary, spend fewer hours sleeping, and are more likely to have a TV or electronic devices in their room. It is a priority to promote access to healthier diets and the promotion of more active and less sedentary lifestyles, both in the family and at school, from an early age. [ABSTRACT FROM AUTHOR]

Introduction: Choline is a critical nutrient for cognitive development, metabolism and liver function, and regulation of homocysteine metabolism. It is necessary for the synthesis of the neurotransmitter acetylcholine, the synthesis of betaine and that of phosphatidylcholine. In the perinatal stage, the contribution of choline is essential to guarantee optimal cognitive development and prevent neural tube defects. In adults and the elderly, choline intake has been associated with better performance in some cognitive functions and a lower incidence of dementia. Despite their important role in health, most groups of the population do not reach their adequate intake of choline, and even some groups, such as pregnant women or childbearing women, have a higher risk of having suboptimal intakes. The main dietary sources of choline are eggs, dairy and meats, so reducing or limiting the consumption of these foods negatively impacts on the intake of this nutrient. Given the need to improve the intake of this vitamin, it is necessary to increase the knowledge that the population has about this nutrient, raising awareness about the importance of choline for health, and its main food sources.
