Dietary pattern transition and its nutrient intakes and diet quality among Japanese population: results from the 2003-2019 National Survey.

While many Asian countries undergo dietary transitions, little is known about Japan's dietary pattern changes and their impact on nutritional intake. We aimed to examine 17-year trends in dietary patterns and nutrient intakes in Japan. Principal component analysis was used to derive dietary patterns. The nutrient intake of subjects with principal component scores in the highest quartiles of each dietary pattern was assessed using the NRF9.3 which is a scale that evaluates the entire diet in terms of nutrient density. Japan. We used data from the National Survey 2003-2019 (67,066 women, 55,133 men). Two common dietary patterns were identified in both sexes: the 'Japanese style' and the 'bread and dairy' pattern. Additionally, two other patterns: 'meat and oil' and 'noodles', were pronounced in men. Over the 17 years, the scores of the 'Japanese style' pattern decreased while the 'meat and oil' and the 'bread and dairy' patterns increased. The nutrition assessment result showed that the highest quartiles of the 'Japanese style' pattern had higher NRF scores (women: 716.0, men: 670.5) (p<0.001), whereas those of the 'bread and dairy' pattern had a lower score (636.9 in women, 661.2 in men) (p<0.001). Trend analysis in this study suggests the ongoing Westernization of diet in Japan. A decreasing trend of the dietary pattern with the most preferable nutrient profile (i.e., the 'Japanese style') might indicate a potential decrease in beneficial nutrient intake and, thus, a deterioration of the nutritional status of the Japanese population.

The trend of correlation changes of macronutrient intakes among different familial pairs: a prospective study among participants of Tehran Lipid and Glucose Study

Background/AimFamilial resemblance in dietary patterns has been a subject of interest, with both genetic and environmental factors playing crucial roles. This study aims to investigate trends in macronutrient intake correlations over a 9-year period among different familial pairs, including parent-offspring, siblings, and spouses, using data from the Tehran Lipid and Glucose Study (TLGS).MethodsThis longitudinal study, conducted within the framework of the TLGS, analyzed data from 1,814 families over a 9-year period. Dietary intakes were assessed using a validated 168-item food frequency questionnaire. Macronutrient intakes were calculated and adjusted for age. Familial correlations were estimated using intraclass correlation coefficients for various familial pairs (parent-offspring, siblings, and spouses) across four consecutive surveys. Changes in correlations were analyzed over 3-year, 6-year, and 9-year intervals, as well as across all four surveys, to determine overall trends in macronutrient intake correlations.ResultsThe results revealed diverse trends in intake correlations for carbohydrates, proteins, fats, and specific fatty acids across familial relationships. Parent-offspring dyads exhibited varied patterns, with some nutrients showing regression to the mean. Sister-sister pairs demonstrated strengthening correlations for energy, carbohydrates, fats, and saturated fatty acids over time. Conversely, brother-sister pairs displayed weakening correlations for most macronutrients, particularly energy, proteins, cholesterol, and fiber. Spouse correlations tended towards regression to the mean for energy, carbohydrates, and fats, and fiber.ConclusionsThe present study illuminates the dynamic nature of familial dietary correlations over time. The contrasting trends between sister-sister and brother-sister dyads suggest a significant influence of gender on shared dietary patterns. These findings underscore the complex interplay of genetic and environmental factors in shaping family dietary behaviors and highlight the importance of considering both gender and relationship type when examining familial nutritional habits.

Caffeine intake from foods and beverages and trends among Chinese children and adolescents: 2004–2018

BackgroundThe popularity of caffeinated foods and beverages poses risks of high caffeine exposure among Chinese children and adolescents. Nevertheless, there is a lack of national assessments on their caffeine consumption. ObjectiveTo estimate daily caffeine intake and analyze time trends among Chinese children and adolescents. MethodsThe study subjects were participants of the China Health and Nutrition Survey in 2004, 2006, 2009 and 2011, and the National Food and Beverage Consumption Survey in 2014 and 2018. Caffeine content was determined using chromatographic instrument. The Monte Carlo simulation was utilized to estimate daily caffeine intake and the Kruskal-Wallis test was used to analyze differences between population characteristics. To examine yearly trends in caffeine intake from 2004 to 2018, the partial Mann-Kendall test was applied. ResultsThe median daily caffeine intake of Chinese children and adolescents was 0.17 (95%CI: 0.15–0.20) mg/kg BW/day. Main contributors were tea (55.52%), sodas (19.52%) and tea beverages (10.37%). Approximately 4.68% of individuals consumed caffeine exceeding 2.5 mg/kg BW/day. Higher caffeine intake was observed in adolescents aged 12–17 years, males, and consumers residing in northeastern China. While no significant overall yearly trends in caffeine intake were detected from 2004 to 2018, there was an increase in intake driven by beverage consumption between 2006 and 2014. ConclusionThis study provided a national assessment of caffeine consumption among Chinese children and adolescents. Caffeinated beverages like tea, soda, and tea beverages emerged as major contributors to caffeine intake. These findings could contribute to the regulation of caffeine consumption and the promotion of healthy habits among children and adolescents.

Intake of free sugar among children and adolescents in Germany declines - current results of the DONALD study.

Our recent analysis reported decreasing trends in intake of free sugar in children and adolescents in Germany. Here we set out to update this analysis with current dietary intake (until 2023) because of the strong public health nutrition interest in sugar intake. In total, 4,218 dietary records kept between 2010 and 2023 by 751 participants (46.0% females, 3-18 years) from the German Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) cohort were examined. Age and time trends in free sugar intake (%E/d) were analysed using polynomial mixed-effects regression models. Median intake data indicate a decline in the intake of free sugar between 2010/2011 (16.7%E) and 2022/2023 (11.7%E). Trend analyses confirmed, that intake of free sugars decreased continuously between 2017 and 2023 (Linear trend: β = -0.4126, p < 0.0001). In addition, free sugar intake changed significantly with age (Linear trend: β = 1.2922, p < 0.0001; quadratic trend: β = -0.08613, p = 0.0094; cubic trend: β = 0.001442, p = 0.1725), i.e. the intake of free sugars increases continuously up to early adolescence (9/10 years) and decreases again thereafter. The intake of free sugar among children and adolescents continued to decline, but still exceeded the WHO recommendations in 2023. Further measures to reduce free sugar intake would therefore be desirable, as well as continuous monitoring of sugar intake levels among this age groups.

Macronutrient and Micronutrient Intake Among US Women Aged 20 to 44 Years

Nutritional status before and during pregnancy is important for maternal health and fetal growth and development. To describe secular trends in nutrient intake from foods, beverages, and supplements among pregnant and nonpregnant women of reproductive age in the US. This was a secondary series of cross-sectional analyses of the 1999-2018 National Health and Nutrition Examination Survey (NHANES). Pregnant (n = 1392) and nonpregnant (n = 9737) women aged 20 to 44 years who provided at least 1 reliable dietary recall were included for analysis. These analyses were performed between February 2022 and July 2024. The primary outcomes included the mean usual intake of macronutrients and micronutrients, as well as the prevalence of inadequate intake of micronutrients. This representative sample included 1392 pregnant women (mean [SE] age, 28.5 [0.3] years) and 9737 nonpregnant women (mean [SE] age, 32.2 [0.1] years). Among pregnant women, a weighted mean (SE) of 27.0% (1.8%) of women were in their first trimester, and 33.8% (2.2%) were in their second trimester. Mean (SE) carbohydrate intake decreased between 1999-2000 and 2013-2018 among pregnant women (306.9 [7.6] to 274.9 [5.7] g/d; β = -2.1 [0.4]; P < .001) and between 1999-2000 and 2017-2018 among nonpregnant women (251.9 [4.9] to 216.9 [3.3] g/d; β = -1.9 [0.4]; P = .002). Between 1999-2000 and 2013-2018, the proportion of pregnant women who consumed below the Estimated Average Requirement of vitamin A increased by 10.9 percentage points (pp) (95% CI, 5.2-16.7 pp), and the proportion of pregnant women who consumed below the Estimated Average Requirement of vitamin C increased by 8.9 pp (95% CI, 3.9-14.0 pp). Similarly, the proportion of nonpregnant women with inadequate intake of vitamin A, vitamin C, and iron increased by 19.9 pp (95% CI, 12.3-27.5 pp), 11.1 pp (95% CI, 4.5-17.7 pp), and 4.9 pp (95% CI, 1.7-8.2 pp), respectively, between 1999-2000 and 2017-2018. The mean (SE) calcium intake increased from 1120.6 (41.4) to 1308.7 (49.0) mg/d for pregnant women (β = 11.7 [4.3]; P = .03) and from 849.5 (19.8) to 981.2 (27.9) mg/d for nonpregnant women (β = 6.7 [2.6]; P = .03; β2 = -1.3 [0.2]; P < .001). Among pregnant women, the prevalence of inadequate intake decreased by 16.1 pp (95% CI, 8.3-23.9 pp) for magnesium (P < .001) and 33.2 pp (95% CI, 24.0-42.4 pp) for vitamin K (P < .001); among nonpregnant women, the proportion with inadequate intake decreased by 16.1 pp (95% CI, 10.4-21.7 pp) for calcium (P < .001), 15.5 pp (95% CI, 7.3-23.6 pp) for magnesium (P < .001), and 33.3 pp (23.5-43.0 pp) for vitamin K (P < .001). This cross-sectional study of pregnant and nonpregnant women of reproductive age found that vitamin A, vitamin C, and iron intake decreased over the past 2 decades, which may have substantial maternal and fetal health implications. By identifying these nutrient gaps and trends in inadequate intake in this at-risk population, scientific, health care, and regulatory communities may be better poised to adopt recommendations to improve nutrient intake.

A longitudinal study among female college students' eating behaviors and food group intake based on the change in eating habit stages

Objectives This study aimed to longitudinally determine the eating behavior and food group intake of female students to examine the relationship between eating behaviors and intention to improve eating habits (change in eating habits stages) and help health education use the behavior change theory.Methods This one-year longitudinal study included 130 female students from Japanese colleges. The stage at which eating habits and behaviors (skipping breakfast, eating out, instant food intake, and snacking) and intake of food groups rich in protein, calcium, vitamins, minerals, carbohydrates, and fats and oils were assessed. The stages were as follows; pre-contemplation or contemplation (lower group), preparation (middle group), and action or maintenance (upper group). A self-assessment questionnaire was administered to evaluate eating behaviors and food group intake frequencies using a 5-point Likert scale. P-values of <.05 were considered statistically significant.Results A cross-sectional comparison of eating behaviors and food group intake scores demonstrated significant differences between the stages only in snacking behavior. The upper group consumed snacks significantly less frequently than the middle and lower groups. After one year, a longitudinal comparison of eating behaviors and food group intake scores revealed significant differences in the intake of food groups rich in vitamins and minerals (green and yellow vegetables), fats and oils in the pre-contemplation stage, intake of food groups rich in vitamins/minerals (green and yellow vegetables) and frequency of skipping breakfast in the preparation stage, and frequency of eating out and snacking in the action stage. Each stage demonstrated a decreasing trend in food intake and an increasing trend in the frequency of skipping breakfast, eating out, and snacking. The percentages of students whose eating habits stage dropped during the second year were 49.0%, 100%, and 77.8% in the preparation, action, and maintenance stages, respectively. This indicates that there are cases in which readiness reverses in stages with improved eating habits.Conclusion In health education on eating habits, it is vital to understand the changes in eating habit stages for each eating behavior and details of actual eating behaviors and habits. Thus, health education should align to the needs of each individual to support them in transforming and maintaining a higher stage of change in their eating habits.

Changes in nutritional status, risk factors and food intake in stroke subjects: cohort study analysis of non-communicable disease risk factors

Background: Stroke is a major cause of death and disability worldwide, affecting 15 million people annually. In Indonesia, the prevalence is 10.9%. Major risk factors include high blood pressure, obesity, inactivity, poor diet, and smoking. Objective: This study aims to analyze long-term trends in risk factors, nutritional status, and food intake among stroke patients from 2011-2021, assessing their impact on stroke incidence. Methods: Data from a longitudinal cohort study of 5,329 subjects, including 215 stroke patients, were analyzed using Microsoft Excel 2019 and SAS software. ANOVA was used to assess annual changes in risk factors, nutritional status, and food intake. Survival analysis was conducted with SAS PROC LIFETEST and PROC LIFEREG. Results: The cohort was primarily female (62.8%), aged 60 or older (57.2%), senior high school education (25.6%), civil servants (30.7%), and low income (57.2%). Significant changes were noted in BMI (p=0.037), fasting blood glucose (FBG) (p=0.001), HDL (p=0.049), abdominal circumference, smoking habits, physical activity (p&lt;0.001), protein intake (p=0.026), and intake of energy, fat, carbohydrates, and sodium (p&lt;0.001). Factors significantly associated with stroke included age, FBG, postprandial glucose, smoking (p&lt;0.0001), LDL (p=0.0380), HDL (p=0.0126), physical activity (p=0.0455), energy intake (p=0.0002), fat intake (p=0.0007), and sodium intake (p=0.0012). Conclusions: The study highlights significant changes in nutritional status, glucose levels, HDL cholesterol, physical activity, and smoking habits. These factors, along with age, cholesterol levels, and dietary intake, impact stroke incidence, underscoring the need for comprehensive stroke prevention strategies.

Assessment of Milk and Beverage Intake Trends During Preschool Age and Modeling the Nutritional Impact of Replacing Nondairy Caloric Beverages with Milk

BackgroundMilk provides essential crucial public health nutrients, including 3–4 nutrients of public health concern, yet dairy consumption has declined over time, leading most Americans to fall short of meeting Dietary Guidelines recommendations. ObjectivesTo investigate milk and beverage consumption trends in preschool-age children, along with nutrient intakes from beverages, and to analyze the potential impact of replacing nondairy beverages with milk through isocaloric substitution. MethodsData from the National Health and Nutrition Examination Survey 2001–2018 for children aged 1–5 y (n = 4696) were used, and milk and other beverages intakes were estimated from the first 24-h in-person dietary recall. Nutrient intakes were determined using the United States Department of Agriculture’s food and nutrient database for dietary studies. Changes in nutrient intakes of children aged 2–5 y were modeled assuming isocaloric substitution with milk of all nondairy beverages consumed during lunch and dinner combined. Sample-weighted analyses were performed using SAS 9.4, and significance was set at P < 0.01. ResultsWith the increasing age of children, the intake of milk decreased, whereas the intake of energy, caloric beverages excluding milk, and sugar-sweetened beverages increased. Daily intakes of energy, protein, fat, saturated fatty acids (SFA), calcium, magnesium, potassium, sodium, vitamin A, folate, vitamin B-12, and vitamin D from caloric beverages including milk decreased with age, whereas the daily intake of fiber and added sugar increased with age. With the isocaloric replacement of nondairy caloric beverages with milk at lunch and dinner among children aged 2–5 y, intake of protein, fat, SFAs, calcium, magnesium, potassium, sodium, vitamin A, folate, vitamin B-12, and vitamin D increased, whereas for intake of carbohydrate, fiber, total sugar, and added sugar decreased. ConclusionsThe current findings indicate that increased efforts are needed to reverse the decrease in milk intake over time and as preschool children age and provide additional evidence to support specific dietary recommendations for milk.

Nutrient utilization and energy balance profile in probiotic supplemented Asian elephants

Aim: A study was methodized to evaluate whether supplementation of probiotics could impact the utilization of nutrients and energy in Asian elephants. Materials and Methods: Eighteen elephants were randomly selected for 60 days experiment including five days of the digestibility trial and divided into three groups with six elephants each i.e. control with no probiotic (T1) and the other two with probiotics Lactobacillus acidophilus in T2 and Saccharomyces cerevisiae in T3 groups at 1 × 109 CFU/gm concentrate per 50 kg body weight/ day orally. Results: : The intakes of ether extract and total ash revealed significant whereas the digestibility coefficients of total ash and acid-insoluble ash exhibited a highly significant effect of treatment. However, other values of intakes and the digestibility coefficients of proximate principles and fibre fractions could not reveal any significant effect. Practical nutritional worth, plane of nutrition and energy balance profile were also found to be non significant among the groups. Increasing trend of intake and the digestibility of energy; and the relative difference was associated with increased DM intake and NDF digestibility. The mean values for TDN%, NR, digestible DM and OM intakes and TDN intake were obtained to be higher for probiotic supplemented groups than the control group. Conclusion: It is concluded that probiotic supplementation could not exhibit any significant effect on nutrients and energy utilization in elephants. However, further research is needed to examine the effects of high doses, strain and viability of the probiotics.

Dietary intake of plant polyphenols: Exploring trend in the Czech population.

This study aimed to determine trend in polyphenol consumption in the Czech Republic during the last three decades. Additionally, it provides a brief overview of the beneficial effects of polyphenols in several body systems. Data from the Phenol-Explorer 3.6, a specialized database of polyphenolic substances, were assigned to the resources of the Czech Statistical Office on the consumption of food and beverages in the Czech Republic for the years 1989-2022. The average daily intake of polyphenols was determined by multiplying the average annual consumption of each type of food by the polyphenol content obtained from the database; results were given in milligrams of polyphenols per inhabitant and day. Since the food items in the data sources are not identical, it was necessary to create an extensive model of food categories. The current value of polyphenol intake is 1,673 mg per day per inhabitant; however, this level most likely reflects methodological underestimation. The favourable increase in dietary polyphenol intake in the Czech population - doubling, to be precise - which we observed from 1989 to 2007, has been replaced by the opposite trend in the last 15 years. The current intake of polyphenols corresponds to the level that was already achieved in 2004. Hydroxycinnamic acids (from the group of phenolic acids) are the most prevalent dietary polyphenols, followed by flavanols (from the group of flavonoids). The most frequent source of polyphenols in the Czech population are non-alcoholic beverages such as coffee, tea and juices, followed by fruits, cereals, and vegetables, respectively. Current trend of dietary polyphenol intake in the Czech population is slightly decreasing. This tendency, lasting since 2008, is indisputably negative. Plant polyphenols offer opportunities for inexpensive interventions in health promotion.

#960 Trends in eGFR and ultra-processed food intake in relationship to income among United States adults

Abstract Background and Aims Ultra-processed foods (UPF) are formulations of ingredients that are mostly of exclusive industrial use and may contain additives like artificial colors, flavors, or stabilizers. The sale and consumption of these foods has been increasing despite their associations with increased risk for several non-communicable diseases including chronic kidney disease. Ultra-processed foods are widely accessible, more shelf-stable and convenient while tending to be more affordable and lower in nutritional quality. The aim of this study was to evaluate trends in kidney function and UPF intake and temporal effect of income among United States (US) adults. Method We used dietary intake data collected with 24-hour dietary recalls from 35160 US adults across 8 cycles of the National Health and Nutrition Examination Survey (NHANES) (from 2003-2004 to 2017-2018 cycles) to categorize intake using the Nova processed food classification system. Poisson regression models were used to assess the 15-year trends in populations at risk for kidney function decline (measured by estimated glomerular filtration rate [eGFR]) and higher percentage of calories from UPF (PC-UPF) consumed along with the temporal effect of income in select subpopulations and adjusted for age and gender and non-linear effects of income and age). Results Over the past 15 years eGFR, PC-UPF, and self-reported income continue to increase among US adults. However, the associations between eGFR, PC-UPF and income are quite complex, vary by subpopulation and non-linearly depend on age. Specifically, among Black adults adjusted for age (age2) and gender, eGFR was the lowest (85 mL/min/1.73 m2, 95% CI: 84.9, 85.0 mL/min/1.73 m2) among those with the lowest ($2,500) and highest ($125,000) income (p = 0.0000000579 for a quadratic term of income), respectively. Hispanic and Mexican Americans also have similar pattern eGFR with the lowest and highest income though the eGFR is consistently higher than White and Black Americans. Across cycles, White Americans with the lowest income ($2,500) have the highest PC-UPF (range: 57-62%, p &amp;lt;2e-16; mean: 59.4%, 95% CI: 59.3, 59.6%) while Black Americans with the lowest ($2,500) and highest income ($125,000) have the highest PC-UPF (range: 53-58%, p &amp;lt;2e-16; mean: 54.8%, 95% CI: 54.3, 55.4%). Income levels does not predict PC-UPF among Mexican Americans. Overall, the PC-UPF is steadily increasing in all population subgroups. Conclusion Among Non-White US adults, higher eGFR was associated with higher income until reaching a group-specific threshold when the relationship reversed. We observed a similar threshold pattern in the association between PC-UPF and income among Black and Hispanic Americans. These complex non-linear relationships between eGFR, PC-UPF and income are driven in part by age-related association and warrant further exploration.

National trends in nine key minerals intake (quantity and source) among U.S. adults, 1999 to march 2020

BackgroundChanges in economy and dietary guidelines brought a great shock to diet quality and meal behaviors, but if these transformations have extended to minerals intake and their sources was still poorly understood. It is essential to evaluate time trends in minerals intake and their sources to inform policy makers.ObjectiveTo investigate trends in minerals intake and their sources among U.S. adults.MethodsThis analysis used dietary data collected by 24-h recalls from U.S. adults (≥ 20 years) in NHANES (1999-March 2020). Minerals intake, age-adjusted percentage of participants meeting recommendations, and minerals sources were calculated among all participants and by population subgroups in each NHANES survey cycle. Weighted linear or logistic regression models were used to examine the statistical significance of time trends.ResultsA total of 48223 U.S. adults were included in this analysis. From 1999 to March 2020, intake of calcium (from 0.94 to 1.02 g/day), magnesium (from 308.07 to 321.85 mg/day), phosphorus (from 1.24 to 1.30 g/day), and sodium (from 3.24 to 3.26 mg/day) from food and beverages (FB) and dietary supplements (DSs) significantly increased, and intake of iron (from 19.17 to 16.38 mg/day), zinc (from 16.45 to 14.19 mg/day), copper (from 1.79 to 1.38 mg/day), and potassium (from 2.65 to 2.50 g/day) from FB + DSs decreased (all FDR < 0.05). Additionally, age-adjusted percentage of participants meeting recommendations for calcium, phosphorus, sodium, and selenium significantly increased, that for iron, potassium, zinc, and copper decreased (all FDR < 0.05). Minerals intake and time trends in minerals intake were highly variable depending on age, gender, race/ethnicity, education, and income. For example, white, higher socioeconomic status participants had a higher minerals intake (e.g. iron, zinc, and copper), but had a greater decrease in minerals intake. Furthermore, the percentage of minerals from milks and DSs decreased, and that from beverages increased.ConclusionFrom 1999 to March 2020, both minerals intake and their sources experienced a significant alteration among U.S. adults. Many differences in minerals intake and their food sources across sociodemographic characteristics appeared to narrow over time. Although some improvements were observed, important challenges, such as overconsumption of sodium and underconsumption of potassium, calcium, and magnesium, still remained among U.S. adults.

Evaluation of the relationship between household economic situation and food group intake in children attending nursery school

Objectives The relationship between household income and dietary intake among older children and adults in Japan has been studied. However, few studies have examined the relationship in younger children, and we believe that this should be taken into consideration from early childhood to correct health disparities. In this study, we examined the relationship between family income and dietary food group intake, and investigated the adequacy of food intake based on the Japanese Food Guide Spinning Top for young children aged 3 to 6 years attending nursery school. The goal of this study was to obtain trends in food intake that can be used to improve poor dietary intake of young children caused by socioeconomic factors.Methods A dietary survey using the food weighing or recording method and a self-administered questionnaire on dietary status were conducted on two non-consecutive days, including weekdays and weekends, from October to December 2019 or 2020. The participants were 761 young children (423 boys and 338 girls) attending nursery schools in seven cities in Japan. Equivalent income was calculated from household income and the number of family members indicated in the dietary status survey. Intake of each food group and consistency with the Japanese Food Guide Spinning Top were compared in five quintiles.Results Compared to the low equivalent income group, the high equivalent income group showed a decreasing trend in cereal intake and an increasing trend in the intake of sugar and sweeteners, green and yellow vegetables, and dairy products. The percentage of the low-income group who did not meet the definition of adequate intake using the Japanese Food Guide Spinning Top was lower for meals that include cereals and grain products, and higher for meals that include meat and fish, vegetable, milk and dairy products, and fruits.Conclusion The lower income group had higher intake of cereals and lower intake of vegetables and fruits compared to the higher income group. This finding is similar to the results of studies in adults and older children. However, based on the Japanese Food Guide Spinning Top, >90% of young children have a diet that fall below the adequate intake of meals, including vegetable dishes and even on weekdays, which suggests a general vegetable deficiency in young children. Multifaceted support is required to address this concern, including measures to correct disparities of income and to ensure desirable nutrient intake in early childhood.

Rabbit intakes and predictors of their length of stay in animal shelters in British Columbia, Canada.

Domestic rabbits (Oryctolagus cuniculus) are the fourth most common species admitted to the British Columbia Society for the Prevention of Cruelty to Animals (BC SPCA) shelter system. However, shelter data analysis has largely focused on cats and dogs and little is known about the population dynamics of rabbits in shelters. We analyzed five years of rabbit records (n = 1567) at the BC SPCA to identify trends in intake and predictors of length of stay (LOS) of rabbits. The majority of rabbits were surrendered by their owners (40.2%), with most rabbits being surrendered for human-related reasons (96.9%). Overall, rabbit intakes decreased over the study period. When analyzing by month of intake, rabbit intakes were found to be the highest in May. Most rabbits in our data were adults (46.7%), non-brachycephalic (66.7%), erect-eared (82.5%), short-furred (76.2%), and subsequently adopted (80.3%). The median LOS of rabbits was 29 days, highlighting the pressing need to improve their time to adoption. A linear model was constructed to identify predictors of LOS of adopted rabbits (n = 1203) and revealed that intake year, intake month, source of intake, age, cephalic type, and breed size significantly predicted time to adoption for rabbits (F(37, 1165) = 7.95, p < 2.2e-16, adjusted R2 = 0.18). These findings help characterize shelter population dynamics for rabbits, shed light on the challenges associated with unwanted rabbits, and offer a foundation for animal shelters to design programs and marketing strategies tailored to reduce LOS of rabbits with particular characteristics. Shelter rabbits represent an understudied population and our study highlights the importance of further research in companion rabbits.

Dietary fat intakes and food sources in early childhood: results from the Melbourne Infant Feeding, Activity and Nutrition Trial (InFANT) Program

Dietary fat is a major energy source and an essential nutrient that supports healthy growth and development in young children(1). Despite the important role of dietary fat in early childhood, our understanding of fat intake trends during this period is limited, particularly among Australian children. Insufficient evidence has led to the establishment of an Adequate Intake (AI) for infants aged 0-12 months in Australia, while no recommendation is available for children ages 1-5 years. This study aimed to comprehensively describe fat intake and major food sources in young Australian children. The data of children at ages 9 months (n = 393), 18 months (n = 284), 3.5 years (n = 244), and 5 years (n = 240) from the Melbourne InFANT Program were used(2). At each time point, child dietary intake data were collected via three 24-hour recalls. Food measurement booklets were utilised to estimate food portions. Food groups and nutrient intakes per day were calculated using the 2007 AUSNUT Food Composition Database. Daily energy (kJ/d) and fat (g/d) intake, the contribution of fat to total energy intake, and key food sources of fat intake were calculated. Descriptive statistics (mean and SD) were used to summarise all data. The mean daily energy intake increased from 3490 kJ/d at 9 months to 5889 kJ/d at 5 years. The mean (SD) fat intake (g/d) was 33.7 (8.0) (Australian AI is 30 g/d) at 9 months, 37.5 (9.5) at 18 months, 44.6 (13.4) at 3.5 years, and 49.0 (15.1) at 5 years. The WHO/FAO recommends that total fat intakes should constitute a minimum of 35% of energy (%E) for children aged 6-24 months, gradually reducing to a range of 25% to 35 %E for children aged 2 to 5 years(3). Notably, 40% of children at 9 months, 76% at 18 months, 14% at 3.5 years, and 12% at 5 years had fat intakes below the WHO/FAO recommendations. In contrast, 24% of children at 3.5 years and 28% at 5 years exceeded the recommendation. At 9 months, the primary source of fat was formula/breastmilk, while at later ages, the major sources were milk/milk products, cakes/cookies, and breads/cereals. The proportion of fat from discretionary foods, such as cakes/cookies, processed meats, butter, oil or fat spreads, increased with age. The percentage of total fat from fish, nuts, and seeds was low, contributing &lt;4 %E at all time points. The study highlights a significant proportion of children exceeding or falling below fat intake recommendations. Moreover, the results suggest low consumption of healthy fat sources such as fish, nuts, and seeds. The study findings will contribute to the refinement of fat recommendations in young Australian children and contribute to interventions that aims to improve fat intakes.

Weight, weight gain and behavioural risk factors in women attending a breast cancer family history, risk and prevention clinic: an observational study

BackgroundWeight and health behaviours impact on breast cancer risk. We describe trends in weight and health behaviours in women at entry to a specialist breast cancer family history clinic in Manchester, UK, and changes after clinic entry.MethodsQuestionnaires were completed at clinic entry (1987–2019, n = 10,920), and updated in 2010–11 (n = 3283). Clinic entry characteristics were compared between joining periods 1989–98, 1999–2008 and 2009–18. Partial Least Squares analysis characterised trends in weight, smoking and alcohol intake by age at entry, year of entry and birth year. Weight changes were compared over time, between joining periods.ResultsObesity at clinic entry increased from 10.6% in 1989–98 to 20.5% in 2009–18. Alcohol intake above recommendations and smoking prevalence decreased from 20.1% to 13.8% and 33.5% to 16.1% respectively. Weight gain was median 9.7 (IQR 1.4–20.6) % between age 20 and clinic entry (mean duration 11.9 ± 5.6 years) and a further 4.5 (0.0–12.5) % between clinic entry and 2010–11 (31.1 ± 10.4 years). Weight gain between age 20 and clinic entry was highest in the most recent joining period.ConclusionsObesity and weight gain are common in women attending a breast cancer family history clinic suggesting a need for weight management advice and support.

Trends in Calcium Intake among the US Population: Results from the NHANES (1999-2018).

Inadequate calcium intake is common in the US. Trends in calcium intake among the US population have been less studied, especially in more recent years. We used data from the National Health and Nutrition Examination Survey (NHANES) 1999-2000 to 2017-2018 to study trends in calcium derived from diet and dietary supplements among the US population aged 2 years, stratified by sex, age group, race, and ethnicity. Among the 80,880 participants included in our study, a substantial portion consistently lacked sufficient calcium intake, even when considering calcium from supplements. Concerning trends were observed over the more recent ten years (2009-2018), with decreased dietary calcium intake and no significant improvement in the prevalence of dietary calcium intake < Estimated Average Requirement (EAR) or the prevalence of taking calcium-containing dietary supplements among them. Decreasing trends in dietary calcium intake were more concerning among men, children, and non-Hispanic Whites. Attention should be given to subgroups with higher calcium intake requirements (e.g., 9-18 years and 60+ years), and subgroups with low levels of dietary calcium and a low prevalence of obtaining calcium from dietary supplements (e.g., the non-Hispanic Black subgroup). Concerning trends of calcium intake were observed among the US population from 2009 to 2018. Tailored guidance on dietary choices and dietary supplement use is required to change consumers' behaviors.

Associations of multiple metal intake with all-cause and cardiovascular mortality in US adults stratified by age and sex: A prospective cohort from the NHANES database study

Aim and objectivesThe relationship between dietary metal intake and mortality risk is controversial, and we investigated the relationship between intake of five metals (iron, copper, selenium, zinc, and magnesium) and all-cause, cardiovascular mortality in the total population, gender subgroups, and age subgroups. Materials and methods17,207 participants from the National Health and Nutrition Examination Survey (NHANES) database from 2009 to 2016 were included in this study. Kaplan-Meier survival curves, multivariate Cox proportional hazards models, and restrictive cubic spline (RCS) curves were used to explore the association between metal intake and all-cause, cardiovascular mortality. ResultsIn this study, the average dietary metal intake of men and older people was lower than that of women and younger people. The RCS curves found in the whole population that all-cause mortality was negative linearly associated with copper intakes, L-shaped with zinc and magnesium intakes. Further subgroup analyses of copper, zinc, and magnesium by age and gender revealed that only magnesium showed statistically significant differences in the age subgroups. In the 20–40 population, there was a non-linear increasing trend in magnesium intake and all-cause mortality, whereas there was a non-linear decreasing trend in the > 60 population. ConclusionThe relationship between metal intake and mortality is more than a simple linear correlation, and differences in age can affect this correlation. In metal exposure studies, different populations can be studied to better determine the effect of metal exposure on mortality.

40 years of adding more fructose to high fructose corn syrup than is safe, through the lens of malabsorption and altered gut health–gateways to chronic disease

Labels do not disclose the excess-free-fructose/unpaired-fructose content in foods/beverages. Objective was to estimate excess-free-fructose intake using USDA loss-adjusted-food-availability (LAFA) data (1970–2019) for high fructose corn syrup (HFCS) and apple juice, major sources of excess-free-fructose, for comparison with malabsorption dosages (~ 5 g-children/ ~ 10 g-adults). Unlike sucrose and equimolar fructose/glucose, unpaired-fructose triggers fructose malabsorption and its health consequences. Daily intakes were calculated for HFCS that is generally-recognized-as-safe/ (55% fructose/45% glucose), and variants (65/35, 60/40) with higher fructose-to-glucose ratios (1.9:1, 1.5:1), as measured by independent laboratories. Estimations include consumer-level-loss (CLL) allowances used before (20%), and after, subjective, retroactively-applied increases (34%), as recommended by corn-refiners (~ 2012). No contributions from crystalline-fructose or agave syrup were included due to lack of LAFA data. High-excess-free-fructose-fruits (apples/pears/watermelons/mangoes) were not included. Eaten in moderation they are less likely to trigger malabsorption. Another objective was to identify potential parallel trends between excess-free-fructose intake and the “unexplained” US asthma epidemic. The fructose/gut-dysbiosis/lung axis is well documented, case-study evidence and epidemiological research link HFCS/apple juice intake with asthma, and unlike gut-dysbiosis/gut-fructosylation, childhood asthma prevalence data spans > 40 years.ResultsExcess-free-fructose daily intake for individuals consuming HFCS with an average 1.5:1 fructose-to-glucose ratio, ranged from 0.10 g/d in 1970, to 11.3 g/d in 1999, to 6.5 g/d in 2019, and for those consuming HFCS with an average 1.9:1 ratio, intakes ranged from 0.13 g/d to 16.9 g/d (1999), to 9.7 g/d in 2019, based upon estimates with a 20% CLL allowance. Intake exceeded dosages that trigger malabsorption (~ 5 g) around ~ 1980. By the early 1980’s, tripled apple juice intake had added ~ 0.5 g to average-per-capita excess-free-fructose intake. Contributions were higher (~ 3.8 g /4-oz.) for individuals consuming apple juice consistent with a healthy eating pattern (4-oz. children, 8-oz. adults). The “unexplained” childhood asthma epidemic (1980-present) parallels increasing average-per-capita HFCS/apple juice intake trends and reflects epidemiological research findings.ConclusionDisplacement of sucrose with HFCS, its ubiquitous presence in the US food-supply, the industry practice of adding more fructose to HFCS than generally-recognized-as-safe, and increased use of apple juice/crystalline fructose/agave syrup in foods/beverages has contributed to unprecedented excess-free-fructose intake levels, fructose malabsorption, gut-dysbiosis and gut-fructosylation (immunogen burden)-gateways to chronic disease.
