RESUMEN

Endometriosis is a chronic gynecological disorder affecting millions of women worldwide, causing chronic pelvic pain, dyspareunia, dysmenorrhea, and infertility, and severely impacting their quality of life. Treatment primarily involves hormonal therapies and surgical excision, but high recurrence rates and the economic burden are substantial. With these challenges, significant discussion surrounds the potential role of dietary patterns in managing endometriosis, making it necessary to bridge this critical gap. This review investigates the current scientific evidence on the dietary patterns (eg, Mediterranean, vegetarian, anti-inflammatory, low-fermentable oligosaccharides, disaccharides, monosaccharides, and polyols [low-FODMAP], and Western-style diets) associated with endometriosis and provides a concise, yet thorough, overview on the subject. In addition, antioxidants, microbiota, and artificial intelligence (AI) and their potential roles were also evaluated as future directions. An electronic-based search was performed in MEDLINE, Embase, Cochrane Library, CINAHL, ClinicalTrials.gov, Scopus, and Web of Science. The current data on the topic indicate that a diet based on the Mediterranean and anti-inflammatory diet pattern, rich in dietary fiber, omega-3 fatty acids, plant-based protein, and vitamins and minerals, has a positive influence on endometriosis, yielding a promising improvement in patient symptoms. Preclinical investigations and clinical trials indicate that dietary antioxidants and gut microbiota modulation present potential new approaches in managing endometriosis. Also, AI may offer a promising avenue to explore how dietary components interact with endometriosis. Ultimately, considering genetic and lifestyle factors, a healthy, balanced, personalized approach to diet may offer valuable insights on the role of diet as a means of symptom improvement, facilitating the utilization of nutrition for the management of endometriosis.

RESUMEN

The systematic review aimed to investigate the associations between index-based dietary patterns and the risk and severity of periodontitis. Four public databases were searched for relevant published articles. Two independent researchers conducted the study selection, quality assessment, and data extraction. Methodological quality of the selected studies was evaluated using Joanna Briggs Institute Checklists. The review was registered with PROSPERO (CRD42023395049). Twenty-five studies were eligible for this review, including 23 cross-sectional studies and two prospective cohort studies. The most utilized dietary indices were the Healthy Eating Index (HEI), the Mediterranean Diet Score (MDS), and the Dietary Inflammatory Index (DII). The results indicated a positive association between higher diet quality (i.e., higher HEI and MDSs and lower DII scores) and healthier periodontal status. Subgroup meta-analysis for four studies utilizing HEI and CDC/AAP case definition indicates the protective effect of higher HEI scores on the risk of periodontitis (OR [95% CI] = 0.77[0.68, 0.88]) with statistical significance (Z = 3.91 [p < 0.0001]). Dietary assessment was conducted by validated food frequency questionnaires (FFQ) in 52% of the studies and 24-h dietary recalls in 36% of the studies. One study utilized a validated 15-item questionnaire to measure patients' adherence to the Mediterranean Diet (QueMD). The quality assessment showed that all studies were of high quality. High HEI and MDSs and low DII scores were associated with a low risk of periodontitis and better periodontal conditions. The standardized and repeatable diet guidelines might be provided for preventing periodontitis. Future prospective studies and clinical trials are needed to confirm this causal association.

RESUMEN

BACKGROUND: Little is known on the prospective associations between an empirically derived dietary pattern (DP) and life satisfaction among adolescents. This PUTRA-Adol follow-up study aimed to assess the prospective associations between the empirically derived DP and life satisfaction during adolescence. METHODS: A total of 585 and 262 adolescents participated in the baseline PUTRA-Adol study in 2016 and PUTRA-Adol follow-up study in 2019-2020, respectively. These adolescents were recruited from three southern states in peninsular Malaysia, namely Negeri Sembilan, Melaka and Johor. Dietary assessments were estimated using a validated food frequency questionnaire (FFQ) while a Multidimensional Students' Life Satisfaction Scale (MSLSS) was used to measure life satisfaction at baseline in 2016 as well as at follow-up in 2019-2020. A DP characterised by foods high in free sugar and energy dense was identified using reduced rank regression (RRR), cross-sectionally at baseline and was reported elsewhere. Similar RRR analysis was used to find a DP that best explained the variation in response variables linked to poorer life satisfaction, including dietary energy density (DED), fiber density, and percentage of energy from total fat and sugar at the PUTRA-Adol follow-up study. Prospective relationship between adherence to the identified DPs and overall life satisfaction scores as well as its domains between 2016 and 2019-2020 were evaluated using generalized estimating equation models (GEE). RESULTS: A DP characterized by high intakes of percentage energy from sugar, fibre and low in DED and percentage energy from total fat was identified at the 2019-2020 follow-up. The identified DP explained 11% of total variations in the response variables and was characterized by high intakes of sweets, sugar sweetened beverages (SSB) and fruits. Female adolescents [67.6(8.9)] had a mean (SD) of life satisfaction that was higher than male adolescents [67.5(10.8)] p < 0.05 in 2019-2020. Prospective analysis found a significant positive association between the identified DP and school domain, in male adolescents (ß = 0.117; 95% CI 0.001, 0.234) and an inverse relationship between the DP z-score and self-domain in all adolescents (ß = - 0.060; 95% CI - 0.115, - 0.005) from 2016 to 2019-2020. CONCLUSIONS: An increasing score for the predominant 'High sugar and High fibre' DP was prospectively associated with increasing life satisfaction score for the school domain in male adolescents and decreasing score for self-domain in both male and females during adolescence. A lifestyle intervention targeting reduced dietary intakes, particularly sugar, may improve life satisfaction in adolescents and promote healthier future without compromising dietary intakes for chronic disease prevention later in life.

RESUMEN

BACKGROUND: College students are vulnerable to high perceived stress (PS) and emotional eating (EE) levels, which are associated with their food consumption. In this study, we aimed to examine the links between perceived stress, emotional eating, and adherence to a healthy eating index. Furthermore, we aimed to test whether sociodemographic data and health measures, including body mass index and physical activity, are associated with perceived stress, emotional eating, or healthy eating index. METHODS: This study included students from King Abdulaziz University. The participants completed validated perceived stress, emotional eating, and short healthy eating index surveys via an online questionnaire from September to December 2022. Univariate linear regression analysis was performed to examine the association between perceived stress, emotional eating, and adherence to healthy eating index using the short healthy eating index. RESULTS: Of 434 students (49.8% male, mean age 21.7 ± 3.0 years), 11.3% had low, 72.0% moderate, and 16.7% high perceived stress. Students with moderate perceived stress had the highest short healthy eating index score (P = 0.001), outperforming those with low and high perceived stress for fruit juice (P = 0.002), fruits (P[Formula: see text]0.001), vegetables (P=0.03), greens and beans (P<0.001), whole grains (P=0.009), and seafood/plant proteins (P = 0.001) consumption. Also, emotional eating was significantly associated with short healthy eating index score (P = 0.04), fruit juice (P = 0.01) fruit consumption (P<0.001), added sugar (P=0.02) and saturated fatty acids (P = 0.03). Academic major was associated with perceived stress (P = 0.006) and emotional eating (p=0.04). Higher physical activity levels were associated with low perceived stress levels (P<0.001) and high short healthy eating index score (P=0.001), while high body mass index was associated with high emotional eating score (P<0.001). CONCLUSIONS: The findings confirmed that students are highly vulnerable to moderate and high perceived stress levels. Furthermore, high perceived stress is inversely associated with adherence to a healthy eating index, especially for fruits, vegetables, greens and beans, whole grains, and seafood and plant proteins consumption. Emotional eating, also, associated with students dietary pattern. Physical activity will be beneficial for reducing the level of perceived stress and improving overall dietary patterns.

RESUMEN

BACKGROUND: The global population is aging rapidly, leading to an increase in the prevalence of cardiometabolic multimorbidity (CMM). This study aims to investigate the association between dietary patterns and CMM among Chinese rural older adults. METHODS: The sample was selected using a multi-stage cluster random sampling method and a total of 3331 rural older adults were ultimately included. Multivariate logistic regression analysis was used to examine the association between the latent dietary patterns and CMM. RESULTS: The prevalence of CMM among rural older adults was 44.64%. This study identified four potential categories: "Low Consumption of All Foods Dietary Pattern (C1)", "High Dairy, Egg, and Red Meat Consumption, Low Vegetable and High-Salt Consumption Dietary Pattern (C2)", "High Egg, Vegetable, and Grain Consumption, Low Dairy and White Meat Consumption Dietary Pattern (C3)" and "High Meat and Fish Consumption, Low Dairy and High-Salt Consumption Dietary Pattern (C4)". Individuals with a C3 dietary pattern (OR, 0.80; 95% CI, 0.66-0.98; p = 0.028) and a C4 dietary pattern (OR, 0.70; 95% CI, 0.51-0.97; p = 0.034) significantly reduced the prevalence of CMM compared with the C1 dietary pattern. CONCLUSIONS: Rural older adults have diverse dietary patterns, and healthy dietary patterns may reduce the risk of CMM.

RESUMEN

Metabolic syndrome has become a significant public health concern. This study aims to investigate the impact of dietary patterns on metabolic syndrome in young adults and how physical activity modulates this effect. A cross-sectional study was conducted at a health management center in Tianjin, China, from September 2022 to March 2023. Participants aged 18-35 years were recruited using convenience sampling. Dietary intake was assessed using a validated food frequency questionnaire. Logistic regression models evaluated associations between these patterns and metabolic syndrome, adjusting for potential confounders. Among 442 participants, four dietary patterns were identified: Legume-Nut, Alcohol-Meat, Sugar-Processed, and Egg-Vegetable. The Legume-Nut dietary pattern was associated with a higher risk of metabolic syndrome (OR = 2.63, 95% CI: 1.08-6.37), while the Egg-Vegetable dietary pattern was associated with a lower risk (OR = 0.26, 95% CI: 0.10-0.70). No significant associations were found for the Sugar-Processed and Alcohol-Meat patterns. Subgroup analysis revealed that the Legume-Nut pattern increased the risk of metabolic syndrome among those with irregular physical activity, whereas the Egg-Vegetable pattern decreased the risk. These findings highlight the significant influence of dietary patterns on the risk of metabolic syndrome in young adults and the modifying effect of regular physical activity, underscoring the need for targeted dietary and lifestyle interventions to prevent metabolic syndrome in this population.

RESUMEN

Study objective: The aim was to quantify and compare the environmental and financial impact of two diets: a heart-healthy Australian diet (HAD) and the typical Australian diet (TAD). Design: The study involved a secondary analysis of two modelled dietary patterns used in a cross-over feeding trial. Setting: The evaluation focused on two-week (7-day cyclic) meal plans designed to meet the nutritional requirements for a reference 71-year-old male (9000 kJ) for each dietary pattern. Main outcome measures: The environmental footprint of each dietary pattern was calculated using the Global Warming Potential (GWP*) metric, taking into account single foods, multi-ingredient foods, and mixed dishes. Prices were obtained from a large Australian supermarket. Results: The HAD produced 23.8 % less CO2 equivalents (CO2e) per day (2.16 kg CO2e) compared to the TAD (2.83 kg CO2e per day). Meat and discretionary foods were the primary contributors to the environmental footprint of the TAD, whereas dairy and vegetables constituted the largest contributors to the HAD footprint. However, the HAD was 51 % more expensive than the TAD. Conclusion: Transitioning from a TAD to a HAD could significantly reduce CO2 emissions and with benefits for human health and the environment. Affordability will be a major barrier. Strategies to reduce costs of convenient healthy food are needed. Future studies should expand the GWP* database and consider additional environmental dimensions to comprehensively assess the impact of dietary patterns. Current findings have implications for menu planning within feeding trials and for individuals seeking to reduce their carbon footprint while adhering to heart-healthy eating guidelines.

RESUMEN

Background: Iron deficiency and iron deficiency anemia cause a huge disease burden worldwide. Diet is an important factor affecting the iron levels. This study aims to explore the dietary patterns of school-aged children in rural areas of Guangzhou and their association with iron deficiency. Methods: Data on dietary surveys, lifestyle, demographic and laboratory tests were gathered from rural school-age children in Guangzhou. Factor analysis was applied to derive dietary patterns. Robust Poisson regression and subgroup analysis were used to analyze the association between dietary patterns and iron deficiency. Results: A total of 2,530 children and adolescents aged 9-17 years were enrolled. The prevalence of iron deficiency was 13.36%. Four dietary patterns were identified including snack and fast-food pattern, fruit and vegetable pattern, cereal and tuber pattern and meat and offal pattern. Both children and adolescents in the Q4 group (the highest propensity) of snack and fast-food pattern and cereal and tuber pattern had a higher risk of iron deficiency than the Q1 group (the lowest propensity). Both children and adolescents in the Q4 group of meat and offal pattern and fruit and vegetable pattern had a lower risk of iron deficiency than the Q1 group. The results of stratified analysis showed the negative effect of snack and fast-food pattern and the protective benefits of meat and offal pattern are more obvious for boys, and the negative effect of cereal and tuber pattern were obvious for girls. The negative effect or protective benefits of the four dietary patterns were obvious for children aged 9-13. Conclusion: Females, older children, and those with shorter sleep duration are at higher risk of iron deficiency. Snack and fast-food pattern and cereal and tuber pattern are risk factors for iron deficiency, and fruit and vegetable pattern and meat and offal pattern are protective factors for iron deficiency. The impact of diet on body iron levels is more obvious in boys and younger children. The findings of this study can provide evidence for formulating prevention and control measures on children and adolescents iron deficiency and iron deficiency anemia.

RESUMEN

OBJECTIVES: During the life cycle of a woman, pregnancy is the period when she is most open to changing her behaviour and lifestyle for the benefit of the child's development. Lifestyle changes include also the diet correction. The objective of the study was to assess, through identified dietary patterns, the diets of women in the second and third trimester of pregnancy in relation to their nutritional status before and during pregnancy. MATERIAL AND METHODS: The study was conducted among pregnant women, participants of childbirth education classes at the Institute of Mother and Child, based on food frequency questionnaire. The study involved 392 women in the age 19-40 years (first single pregnancy without complications). Dietary patterns were identified using the k-means method, based on groups of products. RESULTS: Three dietary patters were identified in the study group of women: dietary pattern 1 - cereal-milk diet, dietary pattern 2 - vegetable-fruit diet and dietary pattern 3 - cottage cheese-vegetable diet. Dietary pattern 3 occurred in 43.9% of underweight women, in 45.5% of women with normal weight and in 43.1% of women with excess body weight. Dietary pattern 1 occurred in about one third of women and dietary pattern 2 in about 20% in each group. A greater diversity in the frequency of identified dietary patterns was observed in relation to weight gain during pregnancy. The identified dietary patterns differed significantly in terms of the profile of macronutrients, most minerals and vitamins - E, C and B group vitamins. CONCLUSIONS: The identified dietary patterns and their energy and nutritional profile indicate the need for monitoring the diets and nutritional education of pregnant women.

RESUMEN

This study provides a comprehensive assessment of how urban-rural divides influence gut microbial diversity and composition across the distinct geographical landscapes of Kazakhstan, elucidating the intricate interplay between lifestyle, environment, and gut microbiome. In this prospective cohort study, we enrolled 651 participants from urban centers and rural settlements across Kazakhstan, following ethical approval and informed consent. Comprehensive demographic, dietary, and stool sample data were collected. 16S rRNA gene sequencing and shotgun metagenomics techniques were employed to delineate the intricate patterns of the gut microbiome. A rigorous statistical framework dissected the interplay between urbanization gradients, geography, dietary lifestyles, and microbial dynamics. Our findings demonstrate a stark microbial divide between urban and rural gut ecosystems. The study found significant differences in gut microbiome diversity and composition between urban and rural populations in Kazakhstan. Urban microbiomes exhibited reduced diversity, higher Firmicutes/Bacteroidetes ratios, and increased prevalence of genera Coprococcus and Parasutterella. In contrast, rural populations had greater microbial diversity and abundance of Ligilactobacillus, Sutterella, and Paraprevotella. Urbanization also influenced dietary patterns, with urban areas consuming more salt, cholesterol, and protein, while rural areas had diets richer in carbohydrates and fiber. The study also identified distinct patterns in the prevalence of antibiotic resistance genes and virulence factors between urban and rural gut microbiomes. This study sheds light on how urbanization may be deeply involved in shaping the intricate mosaic of the gut microbiome across Kazakhstan's diverse geographical and dietary landscapes, underscoring the complex interplay between environmental exposures, dietary lifestyles, and the microbial residents inhabiting our intestines. IMPORTANCE: The study examined gut microbiome composition across diverse geographical locations in Kazakhstan, spanning urban centers and rural settlements. This allows for thoroughly investigating how urbanization gradients and geographic factors shape the gut microbiome. The study's examination of the gut resistome and prevalence of virulence-associated genes provide essential insights into the public health implications of urbanization-driven microbiome alterations. Collecting comprehensive demographic, dietary, and stool sample data enables the researchers to better understand the relationships between urbanization, nutritional patterns, and gut microbiome composition. The findings have important implications for understanding how urbanization-driven microbiome changes may impact human health and well-being, paving the way for tailored interventions to restore a balanced gut microbial ecology.

RESUMEN

PURPOSE: Macronutrient intakes vary across people and economic status, leading to a disparity in diet-related metabolic diseases. This study aimed to provide insight into this by: (1) identifying dietary patterns in adults using reduced rank regression (RRR), with macronutrients as response variables, and (2) investigating the associations between economic status and macronutrient based dietary patterns, and between dietary patterns with central obesity (waist circumference) and systemic inflammation (C-reactive protein [CRP]). METHODS: 41,849 US participants from the National Health and Nutrition Examination Survey (NHANES), 1999-2018 were included. The percentages of energy from protein, carbohydrates, saturated fats, and unsaturated fats were used as response variables in RRR. Multivariable generalized linear models with Gaussian distribution were employed to investigate the associations. RESULTS: Four dietary patterns were identified. Economic status was positively associated with both the high fat, low carbohydrate [ßHighVsLow = 0.22; 95% CI: 0.16, 0.28] and high protein patterns [ßHighVsLow = 0.07; 95% CI: 0.03, 0.11], and negatively associated with both the high saturated fat [ßHighVsLow = -0.06; 95% CI: -0.08, -0.03] and the low alcohol patterns [ßHighVsLow = -0.08; 95% CI; -0.10, -0.06]. The high saturated fat pattern was positively associated with waist circumference [ßQ5VsQ1 = 1.71; 95% CI: 0.97, 2.44] and CRP [ßQ5VsQ1 = 0.37; 95% CI: 0.26, 0.47]. CONCLUSION: Macronutrient dietary patterns, which varied by economic status and were associated with metabolic health markers, may explain associations between economic status and health.

RESUMEN

There are accumulating levels of scientific knowledge concerning the dietary recommendations for the prevention of type 2 diabetes mellitus (T2DM). PURPOSE: This systematic review presents the most recent scientific knowledge concerning dietary recommendations for T2DM published in the English language by various scientific societies during the past 10 years. METHODS: The recommendations are herein presented and discussed in the light of a critical, evidence-based appraisal aiming to provide a comprehensive guide for the clinician in daily practice. RESULTS: In the case of overweight or obesity, the cornerstone of the primary prevention of T2DM is the combination of a healthy body weight (body mass index < 25 kg/m2) or a reduction of fat by at least 7% and the implementation of at least 150 min of moderate physical activity per week. Restriction of calories and of dietary fat is recommended, the latter as well as several dietary patterns providing a holistic approach to dieting and all having been correlated with decreased risk of T2DM. Among these dietary patterns are the Mediterranean diet, the DASH diet (Dietary Approaches to Stop Hypertension), the low-glycemic diet, and the HEI-Healthy Eating Index and AHEI-Alternative Healthy Eating Index. Micronutrient deficiencies of, for example, vitamin D, chromium and magnesium, may be associated with insulin resistance in T2DM. CONCLUSION: Overall, the combination of nutrition through dietary patterns that are mainly plant-based and which emphasize wholegrains, legumes, nuts, fruits, and vegetables and that include only small percentages of refined and processed foods, together with physical activity, has been associated with decreased T2DM risk.

RESUMEN

BACKGROUND & AIMS: Eating patterns significantly impact the weight loss process. This study aimed to investigate the influence of primary eating patterns on weight loss measures in overweight and obese adults using network meta-analysis. METHODS: We systematically searched PubMed, Scopus, Web of Science (WOS), and Google Scholar until May 2, 2023. Our network meta-analysis followed the PRISMA extension guidelines for Comparing Mediterranean, low carbohydrate and low fat diet effects on weight loss among overweight/obese adults. We conducted a Frequentist random-effects network meta-analysis. Summary effects were presented as mean differences (MD) along with corresponding standard deviations (SD). P-scores were used for treatment ranking within the network. RESULTS: Initial literature searches yielded 1574 citations. Ultimately, 1004 participants from 7 RCTs (or 9 trials) met inclusion criteria. All diets resulted in weight loss. Comparatively, the low-carbohydrate diet exhibited a significant decrease in weight loss compared to the Mediterranean diet (MD = -2.70 kg, 95% CI: -4.65, -0.75). Indirect evidence revealed that both the low-carbohydrate diet (MD = -6.31 kg, 95% CI: -11.23, -1.39) and the low-fat diet (MD = -5.61 kg, 95% CI: -10.61, -0.61) significantly reduced weight among overweight/obese adults compared to the standard hypolipemic diet. Rankings indicated the low-carbohydrate diet as the most effective dietary intervention for enhancing weight loss (P-score = 0.8994) and reducing body fat (P-score = 0.7060). CONCLUSIONS: Overall, a low-carb diet appears to be among the most effective approaches for weight loss and body fat reduction. However, it's essential to consider that its efficacy may vary based on factors such as age, gender, genetics, and lifestyle habits.

RESUMEN

OBJECTIVE: To assess the association between dietary patterns and glycemic control among patients with type II diabetes mellitus (T2DM). DESIGN: A cross-sectional study. SITE: The 2015-2018 National Health and Nutrition Examination Survey (NHANES). PARTICIPANTS: A total of 1646 T2DM patients were included, of whom 854 were hyperglycemia. METHODS: Main dietary patterns were identified using the sparse principal components analysis (SPCA). Logistic regression analysis was applied to investigate the association between each dietary pattern and the risk of hyperglycemia with odds ratios (OR) and 95% confidence intervals (CI). SPCA analysis yielded five significant principal components (PC), which represented five main dietary patterns. RESULTS: PC1, characterized by a high intake of sweets, red meat and processed meat, was associated with higher odds of hyperglycemia in patients who underwent hyperglycemic drug or insulin treatments (OR: 1.71, 95% CI: 1.10-2.64). PC5, characterized by high in red meat, while low in coffee, sweets, and high-fat dairy consumption. The relationship between the PC5 and hyperglycemia was marginal significance (OR: 0.63, 95% CI: 0.38-1.02). PC2 was characterized by a high consumption of green vegetables, other vegetables, and whole grains, and low intake of potatoes and processed meat. In patients with the hyperglycemic drug and insulin free, higher PC2 levels were related to lower odds of hyperglycemia (OR: 0.45, 95% CI: 0.21-0.96). CONCLUSIONS: High intake of sweets, red meat, and processed meat might be detrimental to glycemic control in patients with drug-treated T2DM. High in red meat, while low in coffee, sweets, and high-fat dairy consumption may be beneficial to glycemic control. In addition, high consumption of green vegetables, other vegetables, and whole grains, and low intake of potatoes and processed meat may be good for glycemic control in patients without drug-treated T2DM.

RESUMEN

A balanced diet is relevant for neuropsychological functioning. We aimed to analyze the association between dietary patterns and neuropsychological outcomes in a sample of healthy adolescents of the Walnuts Smart Snack (WSS) cohort from Barcelona city. We performed principal components analysis (PCA) to determine dietary patterns in the adolescent sample using a food frequency questionnaire (60 items). Multiple linear regression models were performed to analyze the association between PCA dietary patterns with neuropsychological outcomes: Strengths and Difficulties (SDQ) externalizing and internalizing scores, Attention Network Test (ANT) Impulsivity Index and Emotional Recognition Task (ERT) scores. We additionally adjusted the models for child sex, age, body mass index (BMI), physical activity and maternal education. Six dietary patterns were identified in PCA analyses. "low consumption of calorie-dense foods" dietary pattern had a negative association (protective) with the both SDQ outcomes (p value < 0.001) and "Nuts" dietary pattern showed a negative (protective) association with impulsivity index ( ß 1 = -24.60, 95% CI = -36.80, -12.41, p value < 0.001). Overall, our main results suggest that healthy dietary patterns, including higher intakes of "nuts" and a preference of "low consumption of calorie-dense foods" dietary patterns, could provide a beneficial association with neuropsychological functions during the adolescence period. The associations may include improvements of externalizing and internalizing problem symptoms, and impulsivity.

RESUMEN

Sleep apnoea is a known risk factor for cardiometabolic diseases (CMD), but it is unknown whether sleep apnoea or its symptoms contribute to increased CMD through an association with diet quality. This study assessed the association between sleep apnoea symptoms on future diet quality in the Bogalusa Heart Study (BHS). This prospective study included 445 participants who completed a sleep apnoea questionnaire in 2007-2010 and a FFQ in 2013-2016 (mean follow-up: 5·8 years; age 43·5 years; 34 % male; 71 % White/29 % Black persons). Diet quality was measured with the Alternate Healthy Eating Index (AHEI) 2010, the Healthy Eating Index (HEI) 2015 and the alternate Mediterranean diet score. Adjusted mean differences in dietary patterns by sleep apnoea risk, excessive snoring and daytime sleepiness were estimated with multivariable linear regression. Models included multi-level socio-economic factors, lifestyle and health characteristics including BMI, physical activity and depressive symptoms. Those with high sleep apnoea risk, compared with low, had lower diet quality 5·8 years later (percentage difference in AHEI (95 % CI -2·1 % (-3·5 %, -0·7 %)). Daytime sleepiness was associated with lower diet quality. After adjusting for dietary pattern scores from 2001 to 2002, having high sleep apnoea risk and excessive sleepiness were associated with 1·5 % (P < 0·05) and 3·1 % (P < 0·001) lower future AHEI scores, respectively. These findings suggest that individuals with sleep apnea or excessive sleepiness should be monitored for diet quality and targeted for dietary interventions to improve CMD risk.

RESUMEN

Suboptimal nutrition is a leading cause of cardiometabolic disease and mortality. Biological sex is a variable that influences individual responses to dietary components and may modulate the impact of diet on metabolic health and disease risk. This review describes findings of studies reporting how biological sex may associate with or affect metabolic outcomes or disease risk in response to varying dietary macronutrient content, Mediterranean diet, Western diet, and medical very low-calorie diet. Although few dietary interventions have been specifically designed to identify sex-diet interactions, future studies improving understanding how sex influences dietary responses could inform precision nutrition interventions for disease prevention and management.

RESUMEN

Inadequate adherence to a gluten-free diet in coeliac disease triggers autoimmune reactions and can reduce the quality of life. The strict diet requires constant vigilance, which can cause psychological distress. Our research aimed to assess the quality of life in adult patients with coeliac disease and to find a correlation between quality of life, dietary intervention, and adherence. The study included 51 adult patients with coeliac disease who completed a quality-of-life questionnaire. Adherence was assessed using serological tests and a dietary adherence test. The patients were divided into two groups: those on a gluten-free diet for at least three months (Group I) and newly diagnosed patients (Group II). Group I showed a significant decrease in the dysphoria subscale of the quality-of-life test between the first and last surveys. Poor quality of life was associated with worse adherence in Group II. A higher "Health concerns" quality of life subscale score was also associated with worse adherence in Group II. Our results suggest that dietetic care may be beneficial for patients with coeliac disease by reducing dysphoria. We recommend regular and long-term dietary monitoring from diagnosis to ensure adherence to a gluten-free diet and to maintain quality of life.

RESUMEN

Dietary patterns contribute to overall health and diseases of ageing but are understudied in older adults. As such, we first aimed to develop dietary indices to quantify Mediterranean Diet Score (MDS) utilisation and Ultra-processed Food (UPF) intake in a well-characterised cohort of relatively healthy community-dwelling older Australian adults. Second, we aimed to understand the relationship between these scores and the association of these scores with prevalent cardiometabolic disease and frailty. Our major findings are that in this population of older adults, (a) pre-frailty and frailty are associated with reduced MDS and increased UPF intake; (b) adherence to MDS eating patterns does not preclude relatively high intake of UPF (and vice versa); and (c) high utilisation of an MDS eating pattern does not prevent an increased risk of frailty with higher UPF intakes. As such, the Mediterranean Diet pattern should be encouraged in older adults to potentially reduce the risk of frailty, while the impact of UPF intake should be further explored given the convenience these foods provide to a population whose access to unprocessed food may be limited due to socioeconomic, health, and lifestyle factors.
