Background: Despite the growing interest in the relationship of diet and women’s health conditions, a limited number of Food Frequency Questionnaires (FFQs) have been specifically developed and/or validated for use among women, and those that exist have been primarily developed and validated in non-European countries. This study aimed to evaluate the reproducibility and validity of the FFQ-NutriForHer among young and older Polish women. Methods: The reproducibility and validity of the 138-item FFQ-NutriForHer were evaluated in 121 young (18–30 years) and 88 older women (70–90 years). Reproducibility was assessed using energy-adjusted Pearson and intraclass correlation coefficients (PCCs, ICCs) from two FFQ administrations. Validity was evaluated by comparing energy-adjusted and de-attenuated PCCs between FFQ-mean and 3-day dietary records. The Bland–Altman method estimated mean differences and limits of agreement. Results: The mean PCCs and ICCs for macronutrient reproducibility were 0.69 ± 0.12 and 0.69 ± 0.11 among young women and 0.67 ± 0.06 and 0.65 ± 0.11 among older women, respectively, indicating moderate correlation and reliability in both groups. For micronutrients, the mean PCCs were 0.72 ± 0.05 among young women and 0.69 ± 0.05 among older women, while ICCs were 0.71 ± 0.05 and 0.69 ± 0.09, respectively, indicating a good and moderate correlation and moderate reliability. Mean PCCs for macronutrient validity indicated good concordance with values of 0.51 ± 0.25 among young women and 0.46 ± 0.13 among older women. For micronutrients, the mean PCC for validity was 0.63 ± 0.13 among young women and 0.44 ± 0.14 among older women. Bland–Altman analysis indicated good overall agreement between methods in both groups. Conclusions: Given its high reproducibility and satisfactory validity in both age groups, the FFQ-NutriForHer is a reliable tool for assessing dietary intake and exploring its links to women’s health across different ages.

Background: The Body Roundness Index (BRI) is an emerging anthropometric measure that reflects central adiposity, particularly relevant in ageing populations where body composition and nutritional status undergo significant changes. This study aims to explore patterns linking BRI values, age, energy intake, and micronutrient adequacy using cluster analysis, with a focus on implications for older adults. Methods: Data from 1504 community-dwelling older adults (mean age 74.4 ± 10.8 years) in Poland participating in the PolSenior project were analyzed. K-means cluster analysis was applied to standardized variables (BRI, age, energy intake, and micronutrient adequacy) to identify major participant profiles. Results: The data indicate that older adults, particularly those over 75 years old, are at an elevated risk of inadequate micronutrient intake, especially for essential nutrients such as calcium, magnesium, folate and vitamin D. Three distinct clusters were identified: Cluster 1 (n = 495, 33%): oldest participants, lowest BRI, and insufficient energy and micronutrient intake, indicating a high risk of undernutrition; Cluster 2 (n = 557, 37%): average age, moderate BRI, and highest energy and micronutrient intake, suggesting a potentially excessive energy balance. Cluster 3 (n = 452, 30%): the youngest group with the highest BRI and the lowest energy and micronutrient intake, indicating early-onset central adiposity and poor dietary quality. Conclusions: Three clusters were identified that differed significantly in BRI, age, and adequacy of energy and micronutrient intake. BRI combined with dietary indicators effectively distinguishes nutritional risk profiles among older adults. A low BRI may indicate a risk of undernutrition in advanced age, whereas a higher BRI with low nutrient adequacy suggests poor diet quality, even within the older population. Age-specific and nutrition-sensitive interventions are needed to support healthy ageing.

Background/Objectives: Aging is a natural, gradual, and irreversible process associated with disruptions in homeostasis, causing several unfavorable changes, including changes in body composition. Some studies show that higher water intake can be related to a healthier body composition, but studies in older adults are rare. The aim of this study is to assess the relationship between water intake, dietary acid load, and body composition, and also to assess the interrelationship of these two factors with body composition in older women. Methods: This cross-sectional study involved 195 independently living women aged 65–84. Body composition was assessed using fan-beamed dual-energy X-ray absorptiometry (DXA). Potential renal acid load (PRAL) and water intake were evaluated using the 3-day food record method. Results: Higher water intake was associated with significantly lower android (p = 0.004), gynoid (p < 0.001), and total body fat mass (p = 0.005), as well as higher lean body mass (p = 0.021). Among the assessed anthropometric indicators, only for the appendicular lean mass (ALM) was there a significant difference between the “low-PRAL diet” compared to the “high-PRAL diet” (6.2 ± 0.8 vs. 6.0 ± 0.9 kg/m²; p = 0.045). A “low-PRAL diet” was characterized by a significantly lower energy value, lower protein intake, and a higher plant-to-animal protein ratio than a “high-PRAL diet”. Conclusions: A more acidifying diet pattern appeared to have an adverse effect on lean body mass in older women. The ratio of plant to animal protein may be crucial in this relationship.

Introduction: Dietary supplements have become a common practice, including among children. It is worth noting that supplementation can have a twofold effect: a pro-health effect – improving the nutritional status of the body, or a harmful effect – increasing the risk of nutrient overdose, such as when several preparations are used simultaneously.Objective: The aim of the study was to assess the determinants of dietary supplement consumption by children aged 3-10.Material and Methods: The study used a questionnaire method among parents of 151 children attending kindergarten and elementary schools in the Mazovia Province.Results: Dietary supplements were used by 54.3% of the children surveyed the year before the study. Women with a university education were significantly more likely to supplement their children than women with a secondary or primary education (60.6% and 42.3%, respectively). More children with normal body weight (58.6%) were given supplements than those with overweight and obesity (27.3%). The vast majority of children (66%) took one supplement daily. Concomitant use of supplements with fortified products was observed in 71.4% of respondents. The decision to use a supplement was mainly made by the parents themselves (62%).Conclusions: Educating parents about the benefits and risks of using dietary supplements is necessary. The use of such preparations should be consulted with a specialist, i.e., a doctor or dietician. It is worth noting that a well-balanced diet should provide all the nutrients, vitamins, and minerals for the child’s proper development.

Background: Dietary composition is one of the factors influencing the acid–base balance of the body by providing acid or base precursors. One of the methods for assessing the acid-forming potential of a diet is to calculate its potential renal acid load (PRAL). The aim of this study was to identify the sociodemographic, lifestyle, and health factors related to the PRAL. Methods: Dietary intake was assessed among 133 individuals aged 70+ years using the three-day record method. Results: The average PRAL value was 15.7 mEq/day (range from −42.4 to +101.7). The diets of a majority of the participants (71.4%) had acid-forming potential (PRAL > 0). From a univariate analysis, the acid-forming potential of the diets was linked mainly to women (65.3% in PRAL > 0 group vs. 10.5% in PRAL < 0 group), people using dietary supplements, those who consumed alcohol, those who assessed their health as being at least good, people with osteoporosis, those hospitalized during the previous year, and those with rather lower physical activity. Conclusions: From a multivariate analysis, gender was the strongest predictor of an acid-forming diet, but the following also contributed: an average self-rated health status (compared to good), a good health status (compared to poor), alcohol drinking, hospitalization, lack of nutritional knowledge, and, to a lesser extent, non-frail status (compared to pre-frail). Therefore, more extensive nutritional education in the identified groups is required.

The study aimed to examine socio-demographic and lifestyle determinants, including diet quality, of dietary supplement (DS) use among 2545 students who attended public universities in Warsaw. The data was collected using a self-administered health and lifestyle questionnaire and a 5-day dietary record method. Diet quality was assessed using a Mediterranean Diet Score. To determine the covariates of DS use, multivariate-adjusted logistic regression models with an estimation of odds ratios (ORs) and 95% confidence intervals (95% CIs) were used. The results showed that 41% of participants were DS users. The following predictors of DS use were identified: gender (male vs. female; OR:0.62, 95% CI:0.50–0.79), physical activity (high vs. low; OR:1.79, 95% CI:1.45–2.20), BMI (≥25 vs. 18.5–24.9 kg/m²; OR:0.77, 95% CI:0.61–0.98), cigarette smoking (yes vs. no; OR:0.67, 95% CI:0.52–0.86), and presence of chronic diseases (yes vs. no; OR:2.37, 95% CI:1.89–2.98). Moreover, higher nutritional knowledge, special diet usage, eating more meals/day, and fortified food consumption were determinants of DS use. Adherence to the Mediterranean-style diet was positively associated with DS use, a 1-score increment was associated with a 10% (p-trend = 0.011) higher probability of DS usage. Given that the use of vitamins and/or minerals is common among university students and their users are characterized by eating a higher quality diet, investigating the contribution of DS in overall dietary nutrient intake warrants further study.

Sarcopenia is characterised by a progressive loss of skeletal muscle mass and physical function as well as related metabolic disturbances. While fibre-rich diets can influence metabolic health outcomes, the impact on skeletal muscle mass and function is yet to be determined, and the moderating effects by physical activity (PA) need to be considered. The aim of the present study was to examine links between fibre intake, skeletal muscle mass and physical function in a cohort of older adults from the NU-AGE study. In 981 older adults (71 ± 4 years, 58% female), physical function was assessed using the short-physical performance battery test and handgrip strength. Skeletal muscle mass index (SMI) was derived using dual-energy X-ray absorptiometry (DXA). Dietary fibre intake (FI) was assessed by 7-day food record and PA was objectively determined by accelerometery. General linear models accounting for covariates including PA level, protein intake and metabolic syndrome (MetS) were used. Women above the median FI had significantly higher SMI compared to those below, which remained in fully adjusted models (24.7 ± 0.2% vs. 24.2 ± 0.1%, p = 0.011, η²p = 0.012). In men, the same association was only evident in those without MetS (above median FI: 32.4 ± 0.3% vs. below median FI: 31.3 ± 0.3%, p = 0.005, η²p = 0.035). There was no significant impact of FI on physical function outcomes. The findings from this study suggest a beneficial impact of FI on skeletal muscle mass in older adults. Importantly, this impact is independent of adherence to guidelines for protein intake and PA, which further strengthens the potential role of dietary fibre in preventing sarcopenia. Further experimental work is warranted in order to elucidate the mechanisms underpinning the action of dietary fibre on the regulation of muscle mass.

Ryby i owoce morza są ważnym elementem prawidłowo zbilansowanej diety, na każdym etapie rozwoju i życia człowieka. Spożywanie ryb co najmniej 2 razy w tygodniu zalecane jest przez żywieniowców na całym świecie w celu profilaktyki choroby niedokrwiennej serca i nowotworów. Jednak ze względu na istnienie ryzyka zanieczyszczenia tych produktów m.in. metylortęcią i dioksynami, dla grup wrażliwych (kobiet w ciąży, karmiących piersią oraz dzieci) wprowadzono pewne ograniczenia odnośnie ich spożycia. Jednocześnie podkreśla się, że korzyści zdrowotne wynikające ze spożycia umiarkowanych ilości ryb przez kobiety w ciąży przewyższają ryzyko. W wielu krajach podjęto działania edukacyjne w zakresie zaleceń żywieniowych, dotyczące ograniczenia spożycia określonych gatunków ryb morskich ze względu na zawartość w nich metylortęci. Istotna wydaje się być edukacja kobiet ciężarnych, karmiących piersią oraz w wieku rozrodczym dotycząca spożycia ryb, ich wartości odżywczej oraz wyboru odpowiednich gatunków.

Vitamin/mineral supplement (VMS) use has become increasingly popular in children and adolescents; however, different predictors may be associated with their usage. Therefore, the aim of this study was to compare determinants of VMS use in 1578 children and adolescents. Data was collected among parents of children (≤12 years old) and among adolescents (>12 years old) who attended public schools by a self-administered questionnaire. Multivariate-adjusted logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for determining the predictors of VMS use. In children, the following determinants of VMS use were indicated: socioeconomic status (average vs. very good/good; OR: 1.69, 95% CI: 1.16–2.48), physical activity (1–5 vs. 2; OR: 0.67, 95% CI: 0.46–0.98), and presence of chronic diseases (yes vs. no; OR: 2.32, 95% CI: 1.46–3.69). In adolescents, gender (male vs. female; OR: 0.56, 95% CI: 0.37–0.87), residential area (rural vs. urban; OR: 0.63, 95% CI: 0.40–0.99), BMI (2; OR: 0.35, 95% CI: 0.17–0.73), and health status (average/poor vs. at least good; OR: 1.96, 95% CI: 1.13–3.39) were factors of VMS use. In both groups, the mother’s higher educational level, fortified food consumption and diet modification towards better food choices were predictors of VMS use. In conclusion, most of the predictors of VMS use were different in children and adolescents.

Objectives The aim of this work was to examine the cross-sectional relationship between body composition (BC) markers for adipose and lean tissue and bone mass, and a wide range of specific inflammatory and adipose-related markers in healthy elderly Europeans. Methods A whole-body dual-energy X-ray absorptiometry (DXA) scan was made in 1121 healthy (65–79 years) women and men from five European countries of the “New dietary strategies addressing the specific needs of elderly population for a healthy aging in Europe” project (NCT01754012) cohort to measure markers of adipose and lean tissue and bone mass. Pro-inflammatory (IL-6, IL-6Rα, TNF-α, TNF-R1, TNF-R2, pentraxin 3, CRP, alpha-1-acid glycoprotein, albumin) and anti-inflammatory (IL-10, TGF-β1) molecules as well as adipose-related markers such as leptin, adiponectin, ghrelin, and resistin were measured by magnetic bead-based multiplex-specific immunoassays and biochemical assays. Results BC characteristics were different in elderly women and men, and more favorable BC markers were associated with a better adipose-related inflammatory profile, with the exception of skeletal muscle mass index. No correlation was found with the body composition markers and circulating levels of some standard pro- and anti-inflammatory markers like IL-6, pentraxin 3, IL-10, TGF-β1, TNF-α, IL-6Rα, glycoprotein 130, TNF-α-R1, and TNF-α-R2. Conclusions The association between BC and inflammatory and adipose-related biomarkers is crucial in decoding aging and pathophysiological processes, such as sarcopenia. DXA can help in understanding how the measurement of fat and muscle is important, making the way from research to clinical practice. Key Points • Body composition markers concordantly associated positively or negatively with adipose-related and inflammatory markers, with the exception of skeletal muscle mass index. • No correlation was found with the body composition markers and circulating levels of some standard pro- and anti-inflammatory markers like IL-6, pentraxin 3, IL-10, TGF-β1, TNF-α, IL-6Rα, gp130, TNF-α-R1, and TNF-α-R2. • Skeletal muscle mass index (SMI) shows a good correlation with inflammatory profile in age-related sarcopenia.
