Trends in Sugar From Packaged Foods and Beverages Purchased by US Households Between 2002 and 2020

BackgroundExcess sugar consumption is a public health concern in the United States. How sugar purchases have changed over time, whether there are disparities across subpopulations, and the contribution of various food groups are unclear. ObjectiveTo assess trends in sugar from packaged foods and beverages purchased by US households between 2002 and 2020. DesignThis is an open cohort study. Participants/SettingWe obtained data from the NielsenIQ U.S. Homescan Consumer Panel, which collects data on household purchases of all consumer packaged goods in 52 metropolitan and 24 non-metropolitan markets across the United States. We assessed data on food and beverage purchases for 1,163,447 household-years. Main Outcome MeasuresThe primary outcomes are the total sugar in grams purchased per capita per day and percentage of calories from sugar, by sociodemographic group. Statistical Analyses PerformedWe used linear regression to estimate trends in total grams of sugar per capita per day, percentage of calories from sugar, and percentage of total sugar purchases by food or beverage group. We estimated means for select years and tested for significance compared with 2002 and with the previous timepoint and calculated the overall P-value for the linear trend using time series regression. ResultsTotal sugar purchases decreased over the study period, both in absolute terms (−37.2 g/capita/day; 95% confidence interval [CI], −38.7, −35.6) and as a percentage of total calories purchased (−5.3 percentage points; 95% CI, −5.5, −5.2). Sugar purchases declined for all sociodemographic groups, but disparities have persisted or widened, particularly among individuals who are non-Hispanic Black, low-income, and with lower educational attainment. Beverages’ contributions to sugar purchases decreased 8.1 percentage points (95% CI, −8.4, −7.8). ConclusionIn the United States, purchases of sugar declined, but disparities by socioeconomic status and race or ethnicity persisted or widened. Policies to further reduce sugar consumption and the burden of diet-related disparities are needed.

Associations between nutritional intake, stress and hunger biomarkers, and anxiety and depression during the treatment of anorexia nervosa in adolescents and young adults

Adolescents and young adults (AYA) with anorexia nervosa (AN) frequently have co-occurring anxiety and depression, which can negatively impact prognosis. To inform treatment of co-occurring anxiety and depression, we assessed the association of nutritional intake and hunger/stress hormones on anxiety and depression using a six-month longitudinal study of 50 AYA females receiving care for AN. At baseline and six months, we measured anxiety (Spielberger State/Trait Anxiety Inventory [STAI]), depression (Beck Depression Inventory [BDI]), body mass index (BMI), 3-day dietary intake (total calories and proportion of fat, carbohydrate, protein), and serum cortisol, leptin, and adiponectin. We performed mixed effects linear regression analyses, adjusting for age, duration of AN, and percentage of median BMI (%mBMI). At baseline, median age was 16.3 (interquartile range [IQR] = 2.5) years, duration of AN was 6 (IQR = 8.8) months and %mBMI was 87.2 (IQR = 10.5)%. Fifty-six percent had clinically significant anxiety; 30 % had depression. Over 6 months, participants had significant improvements in %mBMI (+2.2[IQR = 9.2]%, p < .01), STAI (−9.0[IQR = 25.0], p < .01), and BDI (−5.0[IQR = 13.8], p < .01) scores. Participants with larger improvements in caloric intake had greater improvements in STAI (p = .03) and BDI scores (p = .04). Larger improvement in BDI was significantly associated with increased fat intake (p < .01), but not carbohydrate or protein intake. Change in STAI was not associated with changes in fat, carbohydrate, or protein intake. Changes in STAI or BDI scores were not associated with changes in cortisol, leptin, or adiponectin. Increased caloric intake may augment treatment of co-occurring anxiety and depression, and increased fat intake may improve depression for AYA with AN.

Effectiveness of dietary intervention among people with diabetes mellitus: A quasi-experimental study

Abstract Background This study was aimed to evaluate the impact of intervention based on the behaviour change theory on dietary practices among patients with T2DM living in rural areas. Methods A quasi-experimental study was carried out in a rural area of district Fatehgarh Sahib of Punjab, North India. A total of 700 people with T2DM was screened for the eligibility from the randomly selected rural health centeres. The baseline survey included a total of 584 eligible T2DM patients (283 in the intervention and 291 in the control arms), whereas the endline survey included a total of 479 participants (242 in the intervention and 237 in the control arms). A prevalidated and structured food frequency questionnaire at baseline and at the end of 6 months of follow-up. The outcomes of study were mean changes in the total calorie intake from carbohydrate and fat, salt intake, fiber intake and biochemical measurements namely fasting plasma blood glucose, and proportion of population having HbA1c ≤ 7%. Difference in difference analysis (DiD) using Generalized Estimating Equation (GEE) model was applied to adjust for confounders. Statistical significance was considered p &amp;lt; 0.05. Results DiD suggested a significant decrease in mean: total calorie intake (-857 kcal/day; 95% CI -1115 - -599, p &amp;lt; 0.001), calorie intake from carbohydrates (-569 kcal/day; 95% CI -729 - -410, p &amp;lt; 0.001), calories intake from fat (-329 kcal/day; 95% CI -438 - -220, p &amp;lt; 0.001) and dietary salt intake (-5 gm/day; 95% CI -7 - -3, p &amp;lt; 0.001). There was also a significant increase in the mean dietary fiber intake (4 gm/day; 95% CI 0.82 - 7, p = 0.01), a decrease in the mean FPBG (-42 mg/dl; 95%CI: -55 - -29, p &amp;lt; 0.001) and a significant increase in proportion of participants having HbA1c within range (≤7%), (8%; 95%CI:1% - 14%, p = 0.01). Conclusions Study suggested dietary interventions based on the behaviour change theory helped to achieve optimal dietary habits and glycemic stability among patients with T2DM living in rural areas. Key messages • This study emphasised the advantage of behaviour change interventions implementation based on behaviour change theories among patients with T2DM. • T2DM patients can be encouraged to follow healthy dietary habits by using tailored instructions.

Rastame Bar Formulation made from Black Rice Flour and Red Bean Flour as An Alternative to Emergency Food

Geographically and demographically, Indonesia is an area that is prone to natural objects. The National Disaster Management Agency (BNPB) recorded 3,431 natural disasters that have hit various regions in Indonesia from early January to December 2022. Emergency Food Product (EFP) is a product that is designed and used in emergencies without having to go through various cooking processes so that it can be directly consumed. EFP is designed to meet the caloric needs of 233-250 kcal / 50 grams of ingredients. One example of an emergency food product is a snack bar or food bar. This type of research uses the Hedonic Scale Test, which is in the manufacture of Black Rice Flour and Red Bean Flour Rastame Bar products with a Complete Randomized Design (RAL) research design with 3 formulations and 2 repetitions. The organoleptic test was carried out by panelists with a total of 25 moderately trained panelists who were students of the Cirebon Nutrition Study Program level II and III by obtaining the best nutritional content formulation (energy, protein, fat, and carbohydrates) Bar Rastame using the Indonesian Food Composition Table (TKPI) 2017. The treatment used was the ratio of black rice flour to red bean flour respectively by F1 (40%:5%), F2 (35%:10%), and F3 (30%:15%). The selected snack bar is a ratio of 35% black rice flour and 10% red bean flour. The nutritional content of 50 grams of Rastame Bars with a protein content of 5.3 grams, fat content of 4 grams, carbohydrate content of 21.8 grams, and total calories of 143.6 kcal. The characteristics of selected Rastame Bars are a slightly faded blackish color, skimmed milk aroma but not too smelly, hard texture but soft inside, and less sweet taste.

Does nutrition knowledge training improve dietary diversity and nutrition intake? Insights from rural China

AbstractImproving dietary diversity and nutrition intake among rural households is essential to promote sustainable rural development. In this study, we examine whether nutrition knowledge training increases rural households' dietary diversity, nutrition intake, and total calorie intake. We consider three macronutrients (proteins, fats, and carbohydrates) and three micronutrients (vitamin C, iron, and zinc) to capture nutrition intake. The doubly robust inverse probability weighted regression adjustment estimator is employed to estimate survey data of 765 rural households collected by the Institute of Food and Nutrition Development, Ministry of Agriculture and Rural Affairs of China. The results show that nutrition knowledge training enhances household dietary diversity, improves the intake of macronutrients in terms of proteins and fats and micronutrients in terms of zinc, and increases total calorie intake. In addition, the intake of nutrients and calories of males responds to nutrition knowledge training while that of females does not. The dietary diversity of females increases with nutrition knowledge training, whereas that of males is unaffected. {EconLit Citations: I12, I18, Q12, E24}.

The impact of old‐age pension on nutritional outcomes: Evidence from Kyrgyzstan

AbstractExtensive studies have discussed the economic and welfare effects of social pensions worldwide, while scant attention has been paid to their nutritional effects, especially in emerging economies. Using multitopic longitudinal survey data of households and individuals in Kyrgyzstan covering four waves of 2012, 2013, 2016, and 2019, this study aims to examine the impact of an old‐age pension on the nutritional outcomes of the elderly and shed light on their underlying mechanisms. Our empirical identification rests on a propensity score matching with difference‐in‐differences estimation design to address the endogeneity problem of receiving an old‐age pension. Overall, the results indicate that receiving an old‐age pension has a significant and negative impact on body mass index and the probability of being overweight for males, while no significant impact of the old‐age pension has been observed for females. Receiving an old‐age pension has no significant effect on expenditure of food consumption, calorie intake, and macronutrient intake, while it significantly reduces the ratio of protein intake to total calorie intake. We also observe significant heterogeneity in the nutritional effect of an old‐age pension across various education levels and income levels; the negative nutritional effect is more salient for elderly individuals who are relatively poor or who have lower education. Our findings provide profound implications for policies targeting improving the nutritional status of rural residents in emerging economies through the implementation of the old‐age pension [EconLit Citations: H55, I15, I38].

Dietary Sugar Intake Associated with a Higher Risk of Dementia in Community-Dwelling Older Adults.

We have limited evidence for the relationship of high sugar intake with dementia risk. To determine whether high sugar intake is associated with an increased risk of dementia in community-dwelling older adultsMethods:This study included 789 participants of the Rush Memory and Aging Project (community-based longitudinal cohort study of older adults free of known dementia at enrollment), with annual clinical assessments and complete nutrient data (obtained by validated food frequency questionnaire). Clinical diagnosis of dementia is based on the criteria of the joint working group of the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association. We used Cox proportional hazard models. 118 participants developed dementia during 7.3±3.8 years of follow-up. Those in the highest quintile of total sugar intake were twice as likely to develop dementia than those in the lowest quintile (Q5 versus Q1:HR=2.10 (95% CI: 1.05, 4.19) when adjusted for age, sex, education, APOEɛ4 allele, calories from sources other than sugar, physical activity, and diet score. Higher percent calories from sugar were positively associated with dementia risk (β=0.042, p = 0.0009). In exploratory analyses, the highest versus lowest quintile of fructose and sucrose in the diet had higher dementia risk by 2.8 (95% CI: 1.38, 5.67) and 1.93 (95% CI: 1.05, 3.54) times, respectively. A higher intake of total sugar or total calories from sugar is associated with increased dementia risk in older adults. Among simple sugars, fructose (e.g., sweetened beverages, snacks, packaged desserts) and sucrose (table sugar in juices, desserts, candies, and commercial cereals) are associated with higher dementia risk.

FRI006 Appetite And Food Intake-regulating Hormones In Patients With Craniopharyngioma

Abstract Disclosure: C.S. Martins: None. M.C. Nogueira: None. A. Bueno: None. A.S. Berbel-Júnior: None. A.C. Moreira: None. S.R. Antonini: None. M. De Castro: None. Purpose: In patients with adamantinomatous craniopharyngiomas (aCP), hypothalamic obesity may occur due to hypothalamic involvement by the tumor or therapeutic interventions. Studies on appetite sensations and modulation of orexigenic and anorexigenic hormones may contribute to understand the pathogenesis of obesity in aCP patients. Patients and Methods: Fifteen patients (9F, 6M; 31.1±12.0 years) presenting aCP submitted to surgical resection and 15 controls paired by sex, age (31±11.7 years) and Body Mass Index (BMI) were evaluated. Leptin and adiponectin were measured in basal conditions, whereas glucose, insulin, GLP-1, PYY and ghrelin levels were assessed in basal conditions and 30, 60, 120 and 180 minutes after a standard meal test consisted by 70 g of hyposodic soy protein isolate-based powder diluted in 250 mL water to be consumed in up to 10 minutes, resulting in a drink of 315 Kcal with 44.1 g carbohydrate, 10.5 g fat, and 11.0 g protein (56%, 30%, and 14% of total calories, respectively). At the same time points, sensations of hunger, fullness and prospective food consumption were measured by a Visual Analogic Scale (VAS) composed of horizontal lines. Individuals were asked to mark across the line the point correspondent to their sensations, and the distance to the left end of the line was quantified. The term “hunger” was evaluated by the question “How much hunger do you feel?” The answers at the VAS were “I’m not hungry at all” and “I’ve never been so hungry.” The feeling of fullness was evaluated by the question “How satisfied are you?” and the answers were “I am completely empty” and “I am completely full.” Prospective consumption was evaluated by the question “How much do you think you can eat?” and the answers were “nothing” and “too much”. Results: Patients’ BMI were 30.9 ± 7.6 kg/m2. In aCP patients, differently from controls, the decrease of hunger from baseline to 60 minutes after the meal was not observed, demonstrating a more transient reduction in the sensation of hunger. In addition, a decrease of fullness sensation from 30 to 120 minutes (p=0.03) was observed, demonstrating a less durable sensation of fullness. There was a tendency towards higher fasting leptin concentrations in patients with aCP (p=0.06), while adiponectin levels were lower in patients (p=0.002). Insulin (p=0.01) and HOMA-IR (p=0.001) were higher in aCP patients compared to controls at 3 hours after meal, whereas GLP-1 (P=0.03) and PYY (p=0.02) were higher at 2 hours after the meal. PYY and ghrelin showed earlier postprandial rise and fall, respectively, in aCP patients. Conclusions: After the test, aCP patients exhibited more transient reduction in the sensation of hunger and less durable sensation of fullness than controls. Changes in appetite sensations and unregulated secretion of orexigenic and anorexigenic hormones may contribute to increased food intake and to the pathogenesis of obesity in aCP patients.

Assessment of the severity and incidence of Septoria tritici blotch (Zymoseptoria tritici) of wheat in Northwestern Ethiopia

Wheat is a global staple crop, which contributes 20% of the total dietary proteins and calories. Despite its importance, wheat production and productivity are affected by various biotic and abiotic stresses. Septoria leaf blotch is one of the biotic stresses that decreases production and grain quality. A field survey was conducted in twenty-four districts of Northwestern Ethiopia to figure out its distribution, incidence, severity, and association with agronomic practices and agroecological factors. Logistic regression models were used to figure out associations of the disease intensity with independent variables. The highest mean disease incidence and severity were 90.7 and 46.67%. High severity and incidence were associated with early planting, milk growth stage, and vertisol soil type. This shows that Septoria leaf blotch is a major biotic constraint for the study area. Therefore, effective, and suitable disease management options should be developed to improve the productivity of the crop in Northwestern Ethiopia.

Sleep Variability, Eating Timing Variability, and Carotid Intima-Media Thickness in Early Adulthood.

Background Day-to-day variability in sleep patterns and eating timing may disrupt circadian rhythms and has been linked with various adverse cardiometabolic outcomes. However, the extent to which variability in sleep patterns and eating timing relate to atherosclerotic development in subclinical stages remains unclear. Methods and Results Generally healthy adults (N=62, 29.3±7.3 years, 66% female) completed 14 days of sleep and dietary assessments via wrist accelerometry and photo-assisted diet records, respectively. Variability in sleep duration, sleep onset, eating onset (time of first caloric consumption), eating offset (time of last caloric consumption), and caloric midpoint (time at which 50% of total daily calories are consumed) were operationalized as the SD across 14 days for each variable. Separate regression models evaluated the cross-sectional associations between sleep and eating variability metrics with end-diastolic carotid intima-media thickness (CIMT) measured via ultrasonography. Models adjusted for age, sex, systolic blood pressure, sleep duration, and total energy intake. Each 60-minute increase in sleep duration SD and sleep onset SD were associated with a 0.049±0.016 mm (P=0.003) and 0.048±0.017 mm (P=0.007) greater CIMT, respectively. Variability in eating onset and offset were not associated with CIMT; however, each 60-minute increase in caloric midpoint SD was associated with a 0.033±0.015 mm greater CIMT (P=0.029). Exploratory post hoc analyses suggested that sleep duration SD and sleep onset SD were stronger correlates of CIMT than caloric midpoint SD. Conclusions Variability in sleep patterns and eating timing are positively associated with clinically relevant increases in CIMT, a biomarker of subclinical atherosclerosis, in early adulthood.

Elektrostimülasyon ve Zumba Egzersizinin Sedanter Kadınlarda Bazı Fiziksel ve Fizyolojik Parametreleri Üzerine Etkilerinin Karşılaştırılması

The aim of this study is to compare the effects of Electrostimulation (EMS) exercise, which is a popular research topic recently, whose effectiveness and benefits are frequently stated in the literature, and zumba exercise, which is also a popular type of exercise, on some physical and physiological parameters in healthy sedentary women. A total of 30 women (35.8 ± 1.4 years) volunteered for this study. The participants were randomly divided into EMS (n:15) and Zumba (n:15) groups. Then, for a total of 6 weeks, the EMS group performed EMS exercise two days a week, and the Zumba group performed Zumba exercise two days a week. The body composition, blood pressure, maximal oxygen consumption (VO2max), strength performance and determined blood parameters of the participants were evaluated at the beginning and end of the study. Each exercise session was followed by heart rate monitoring system in order to evaluate the participants' maximal, average heart rate and total calories burned. Moreover, rate of perceived exertion was recorded at the end of each exercise with the Borg scale. When intergroup comparison performed, a statistically significant difference was found in favor of the Zumba group in the values of body weight, body mass index (BMI), body fat percentage and. VO2max There was no statistically significant difference between the groups in strength and blood lipid parameters. It can be said that both EMS and zumba practices have positive effects on body composition, strength and blood lipid levels when the duration of each session and the total duration of the exercises as well as intra-group changes are evaluated.

Higher consumption of ultra-processed food is associated with cardiovascular risk in Korean adults: KNHANES 2016–2018

BackgroundExcessive consumption of ultra-processed foods (UPFs) has been linked to an increased risk of cardiovascular disease. We aimed to investigate the association between the percentage of energy intake from UPFs and the American Heart Association’s cardiovascular health (CVH) metrics in Korean adults.MethodsThis study analyzed adults aged 40 years and older using data from the Korean National Health and Nutrition Examination Survey 2016–2018 (n = 9,351). All foods or beverages reported in a 24-h dietary recall were categorized using the NOVA system, and the percentage of energy from UPFs was calculated. Each CVH metric was scored 0–2 (poor, intermediate, ideal). The sum of six component scores was classified as inadequate, average, or optimum. Multinomial logistic regression models were used to estimate the covariate-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for inadequate and average CVH versus optimum CVH.ResultsThe mean percentage of energy from UPFs was 24.2%. After adjusting for covariates, participants in the highest UPF quartile had 26% higher odds of having inadequate CVH than those in the lowest quartile (OR 1.26, 95% CI 0.94–1.69, P-trend = 0.03). The percentage of energy from UPFs was positively associated with current smoking, physical inactivity, body mass index, and total cholesterol and was inversely associated with blood pressure and fasting glucose.ConclusionThe percentage of energy from UPFs accounted for one-fourth of total calorie intake in Korean adults aged 40 years and older. Higher UPF consumption was associated with poorer CVH, underscoring the potential of limiting UPF consumption as a preventative measure for cardiovascular diseases.

The diet quality of well adolescents: Do they really eat poorly?

BackgroundA common assumption is that adolescents have poor eating habits. However, there is minimal data regarding adolescents’ intake of macronutrients (i.e. protein, carbohydrate, and fats) and micronutrients (i.e. vitamins and minerals). In addition, few studies have used the Healthy Eating Index-2010 (HEI-2010) to assess diet quality of well adolescents. ObjectiveTo determine diet quality among patients presenting for well care by using NDSR (Nutrition Data Systems for Research) nutrition analysis software and by calculating HEI-2010 scores. MethodsA convenience sample of adolescents presenting to clinic for well care was recruited. Participants completed a 24 hour dietary recall using the multiple pass method, a validated interviewing technique. Results for each participant were entered into NDSR version 2014, which provides a detailed nutrition analysis, and these results were also used to calculate a HEI-2010 score, which measures how well dietary intake conforms to the Dietary Guidelines for Americans in terms of amounts consumed from each food group. ResultsData from 48 adolescents (30 female, 18 male; mean age 16.5, range 12–20 years; 18 Hispanic, 11 Black, 5 White, 14 other) were analyzed. Body-mass-index (BMI) ranged from 16.0 to 38.1. Average total calories were 2054 (but there was a wide range of 683 to 4801 calories). Average calories for females and males were 1723 and 2604, respectively. Average percentages of calories from macronutrients were 33.2% from fat, 50.5% from carbohydrate, and 16.3% from protein. Micronutrient content was very low (< 53% of recommended Daily Values) for vitamins E and D; moderately low (61–76%) for zinc, magnesium, potassium and copper; minimally low (86–97%) for calcium, iron and vitamin B12; and normal (≥100%) for thiamin, riboflavin, niacin, folic acid, phosphorus, manganese, selenium and vitamins C, K, and B6. HEI scores were <50 (“poor”) for 20 subjects and 51–79 (“needs improvement”) for 13 subjects. Calorie consumption was insufficient to calculate an HEI score for 15 subjects and no subjects had an HEI score >80 (“good”). ConclusionOn some measures (distribution of macronutrients, intake of most vitamins and minerals), the adolescents in this study had sufficient diets by NDSR calculations. However, no subject had an HEI score indicative of good diet quality. It is possible that adolescents are consuming adequate macro- and micronutrients in the setting of processed, fortified foods, but that optimal consumption from each food group is lacking, resulting in lower diet quality scores on the HEI.

School-Level Socioeconomic Status and Nutrient Content of Outdoor Food/Beverage Advertisements.

We examined if areas around schools with more students of lower socioeconomic status (SES) have more total food/beverage advertisements and/or more advertisements with poorer nutritional content as compared to areas around schools with fewer students with lower SES. All outdoor food/beverage advertisements within a half-mile radius of 47 middle and high schools in the United States were objectively documented in 2012 and coded for nutritional content. The total number of advertisements and the macronutrient and micronutrient contents (total calories, fat (g), protein (g), carbohydrate (g), sugar (g), and sodium (mg)) of food and beverage items depicted in the advertisements were calculated. In total, 9132 unique advertisements were recorded, with 3153 ads displaying food and beverages that could be coded for nutrient content. Schools located in areas of lower SES (≥60% students receiving free/reduced-price lunch) had significantly more advertisements displaying food and beverages that could be coded for nutrient content (z = 2.01, p = 0.04), as well as advertisements that contained more sodium (z = 2.20, p = 0.03), as compared to schools located in areas of higher SES. There were no differences in calorie, fat, protein, carbohydrate, or sugar content. Policies to reduce the prevalence of outdoor food and beverage advertising are warranted.

Association of free-living diet composition with plasma lipoprotein(a) levels in healthy adults

BackgroundLipoprotein (a) [Lp(a)] is an apoB100-containing lipoprotein with high levels being positively associated with atherosclerotic cardiovascular disease. Lp(a) levels are genetically determined. However, previous studies report a negative association between Lp(a) and saturated fatty acid intake. Currently, apoB100 lowering therapies are used to lower Lp(a) levels, and apheresis therapy is FDA approved for patients with extreme elevations of Lp(a). The current study analyzed the association of free-living diet components with plasma Lp(a) levels.MethodsDietary composition data was collected during screening visits for enrollment in previously completed lipid and lipoprotein metabolism studies at Columbia University Irving Medical Center via a standardized protocol by registered dietitians using 24 hour recalls. Data were analyzed with the Nutrition Data System for Research (Version 2018). Diet quality was calculated using the Healthy Eating Index (HEI) score. Fasting plasma Lp(a) levels were measured via an isoform-independent ELISA and apo(a) isoforms were measured using gel electrophoresis.ResultsWe enrolled 28 subjects [Black (n = 18); Hispanic (n = 7); White (n = 3)]. The mean age was 48.3 ± 12.5 years with 17 males. Median level of Lp(a) was 79.9 nmol/L (34.4–146.0) and it was negatively associated with absolute (grams/day) and relative (percent of total calories) intake of dietary saturated fatty acids (SFA) (R = -0.43, P = 0.02, SFA …(% CAL): R = -0.38, P = 0.04), palmitic acid intake (R = -0.38, P = 0.05), and stearic acid intake (R = -0.40, P = 0.03). Analyses of associations with HEI score when stratified based on Lp(a) levels > or ≤ 100 nmol/L revealed no significant associations with any of the constituent factors.ConclusionsUsing 24 hour recall, we confirm previous findings that Lp(a) levels are negatively associated with dietary saturated fatty acid intake. Additionally, Lp(a) levels are not related to diet quality, as assessed by the HEI score. The mechanisms underlying the relationship of SFA with Lp(a) require further investigation.

Influence of HIV/AIDS Infection on Immunological and Nutritional Status in Adults and Older Adults: A Cross-Sectional Study in Kingdom of Bahrain.

Background and Objectives: HIV infection is a global public health problem that can lead to the progression of AIDS. Nutritional status and biochemical markers can significantly contribute to the progression of AIDS in HIV/AIDS patients. The main objective of this study is to examine the association between nutritional and biochemical markers as well as BMI in HIV/AIDS patients in the kingdom of Bahrain. Methods: A retrospective cohort study, including 300 patients (248 males and 52 females) with HIV/AIDS in Bahrain, was carried out. Various biochemical markers were collected from patients' medical records, including CD4+ T cell count, albumin, Hb, HCT, MCV, WBCs, and creatinine. A semi-structured questionnaire using a standardized food frequency questionnaire (FFQ) was used, from which total energy and total macronutrients were calculated. Results: The mean BMI of the participants was 27.20 kg/m2, and none of the participants had a BMI lower than 18.5 kg/m2 (underweight). The majority of patients' dietary intake of macronutrients and total calorie intake were either within or above the recommended RDA levels. The results also showed that all of the mean values of the nutritional and biochemical markers (CD4+ T cell count, albumin, Hb, HCT, MCV, WBCs, and creatinine) were within the normal reference ranges. A significant positive correlation between CD4+ T cell count, Hb, HCT, and albumin at the <0.05 level was found. There was no significant correlation between CD4+ T cell count and MCV, WBCs, and creatinine. A positive significant correlation was found between BMI, CD4+ T cell count, and WBCs at the <0.01 level. Conclusion: The BMI values were significantly correlated with the biochemical markers of AIDS progression. The dietary patterns of the participants were undiversified, with a high prevalence of obesity and overweight. Malnutrition among this study population was not present.

Diet and mitonuclear haplotype interactions affect growth rate in a slime mould.

Trait expression in metazoans is strongly influenced by the balance of macronutrients (i.e. protein, carbohydrate and fat) in the diet. At the same time, an individual's genetic background seems to regulate the magnitude of phenotypic response to a particular diet. It needs to be better understood whether interactions between diet, genetic background and trait expression are found in unicellular eukaryotes. A protist-the slime mould, Physarum polycephalum can choose diets based on protein-to-carbohydrate (P:C) content to support optimal growth rate. Yet, the role of genetic background (variation in the mitochondrial and nuclear DNAs) in mediating growth rate response to dietary P:C ratios in the slime mould is unknown. Here, we studied the effects of interactions between mitochondrial and nuclear DNA haplotypes and diet (i.e. G × G × E interactions) on the growth rate of P. polycephalum. A genetic panel of six distinct strains of P. polycephalum that differ in their mitochondrial and nuclear DNA haplotypes was used to measure growth rate across five diets that varied in their P:C ratio and total calories. We first determined the strains' growth rate (total biomass and surface area) when grown on a set menu with access to a particular diet. We then assessed whether the growth rate of strains increased on a buffet menu with access to all diets. Our findings show that the growth rate of P. polycephalum is generally higher on diets containing more carbohydrates than protein and that total calories negatively affect the growth rate. Three-way interactions between mitochondrial, nuclear haplotypes and dietary P:C ratios affected the strains' surface area of growth but not biomass. Intriguingly, strains did not increase their surface area and biomass when they had access to all diets on the buffet menu. Our findings have broad implications for our understanding of the effect of mitonuclear interactions on trait expression across diverse eukaryotic lineages.

Food consumption and adherence to dietary guidelines among Jordanian children and adolescents

Background: To evaluate the energy and macronutrient intake of Jordanian children and adolescents, and how closely they adhere to dietary recommendations. Methods: This cross-sectional study used data from Jordan's Population-based Food Consumption Survey, a household population-based study that was conducted in Jordan between 2021-2022 (561 children and adolescents 8-19 years). Dietary intake was assessed using the two non-consecutive 24-hour dietary recall method (24-h DR). The estimated food group and nutrient intakes were compared to nutritional recommendations, including MyPlate dietary guidelines. Results: The prevalence of overweight/obese individuals based on body mass index (BMI) was 44%, and the average waist-to-height ratio (WHtR) was 24.7%. Compared to MyPlate dietary guidelines, children and adolescents had a higher added sugar intake (57g/day). Also, the consumption of vegetables, fruits, and dairy fell short of MyPlate dietary guidelines. The total discretionary calorie intake in children and adolescents was approximately one-third of the total energy intake. Conclusion: The food consumption of Jordanian children and adolescents includes high intakes of discretionary calories, with a low intake of fruits, vegetables, and dairy products. The prevalence of overweight/obesity was elevated compared to international norms.

Abstract 107: Longitudinal Associations Of Dietary Fructose And Psychological Stress With Vascular Aging Index And Incident Cardiovascular Disease Among Us Black And White Adults In The CARDIA Study

Background: Cardiovascular diseases (CVD) is the leading cause of death and disability worldwide. CVD risk increases exponentially with age, largely due to pathophysiological changes within the vasculature. As per AHA’s Life’s Essential 8, modifiable lifestyle factors such as diet and psychological stress are important predictors of CVD. We designed this study to assess how dietary behaviors, specifically sucrose, fructose and sodium, and endured psychological stress in young adult men and women impact the vascular aging index (VAI) and CVD risk by mid-life. Methods: All data were obtained from the Coronary Artery Risk Development in Young Adults (CARDIA) Study. We used the data from black and white men and women (n=2656) who had undergone carotid artery ultrasound Doppler scans at visit 7 (year 20 of follow-up) and used these measures to calculate the VAI, as shown previously. Baseline demographics, dietary data and stress/depression measures (CES-D scores) were obtained from visits 1 (at enrollment, year 0) and 7 and compared (men vs. women) with Kruskal-Wallis and Pearson’s chi-square tests. Regression analyses were used to assess the predictive value of these variables on VAI. Cox regression analyses were conducted to assess the risk of fatal and non-fatal CVD, hypertensive CVD, and stroke. Results: Significant associations were found for fructose intake (expressed as percent total calories, P=0.042) and BP &gt;30/80 mmHg (P=0.025) at baseline with VAI in men but not women. Conversely, CES-D scores at baseline were significantly associated with VAI in women (P=0.014) but not men. On Cox regression analyses, baseline BMI was significantly associated with the incidence of any CVD (HR=1.065, P &lt;0.001), hypertensive CVD (HR=1.083, P&lt;0.001) and stroke (HR=1.068, P=0.002) 30 years later. Dietary fructose intake recorded in mid-life was significantly associated with the incidence of any CVD (HR=1.041, P=0.044), and having BP &gt;130/80 mmHg at baseline was associated with stroke (HR=1.996, P=0.029). No sex differences were noted in the Cox regression analyses. Conclusion: Our results suggest that in young adult black and white men but not women BMI and fructose consumption, but not sodium are associated with increased VAI and incidence of CVD by mid-life.

EFFECT OF LATE-NIGHT EATING ON HEALTH: A SURVEY FROM UNIVERSITY STUDENTS

Late night eating is characterized by eating after 10 pm or eating 2 hours before sleep at least 3 times per week, it is also characterized by the number of late-night eating episodes and the proportion of total daily calories consumed during the eating episode. This cross-sectional study aimed to investigate the association between late-night eating habits and various health issues among individuals from multiple universities in Pakistan. Data was collected from over 15 universities, including the University of Lahore, Comsats University, Bahria University, Punjab University, Karachi University, and de Montmorency College of Dentistry. A non-probability convenient sampling technique was employed to select more than 150 participants for data collection. Participants were evaluated using a pre-tested questionnaire. Dietary choices, circadian rhythms, psychological stress, and social influences are just a few of the things that have an impact on late-night eating habits and the health problems that go along with them. The results of the study indicated that a significant proportion of the participants experienced health issues as a result of their late-night eating habits. Among the observed health issues, headache was the most prevalent, affecting 75% of the participants, followed by sleep disorders (66%), depression (63%), and acidity (59%). In contrast, a lower percentage of individuals reported issues such as diarrhea (29%), vomiting (25%), and piles (21%). For late night eating, majority of the participants approximately 95 % were preferring consuming meals, fried foods and confectionary items for late night snacking and the least consumption was observed of corn and popcorn that accounted for 60 %.and 57 % respectively. It was concluded that late night eating is associated with many digestive, metabolic and psychological issues that have a negative impact on overall health of an individual. The increase in frequency and size of late-night eating in adolescence and adulthood will lead them towards an unhealthy aging.
