RESUMO
Background and Aim: Literature suggests that individuals who have recovered from COVID-19 may experience post-COVID conditions, including sleep problems and alterations in smell or taste. Thus, this study aims to compare the sleep quality, diet quality, and weight change between COVID-19-recovered patients and healthy controls. Methods: A matched case-control study involving young adults aged 18-30 years was conducted in the Klang Valley of Malaysia. The young adults were matched in a 1:1 ratio based on their sociodemographic characteristics, including gender, age, marital status, ethnicity, educational attainment, employment status, and monthly earned income. The Pittsburgh Sleep Quality Index was utilized to evaluate sleep quality, and the Diet Quality for Malaysia was used to determine the diet quality of all young adults. The young adults retrospectively recalled their prepandemic body weight in February 2020, while their current body weight in February 2023 was measured using a TANITA HD-314 digital weighing scale. Results: Emerging findings suggest that sleep quality and weight change were comparable between COVID-19-recovered patients and healthy controls. However, healthy controls were reported to have a more diversified diet than COVID-19-recovered patients. Nevertheless, no significant main effects or interaction effects of sleep and diet quality on weight change were observed in COVID-19-recovered patients or healthy controls. In this study, young adults also reported suffering from sleep deprivation and deficiency due to the pandemic. Conclusion: Intervention programs that emphasize avoiding stimulants before bedtime for healthy controls, promoting the importance of having a diversified and balanced diet among the COVID-19-recovered patients, and achieving an ideal body weight for all young adults should be conducted after the COVID-19 pandemic.
RESUMO
Introduction: Research exploring factors that may influence the diet quality of adolescents in the Middle East are very limited. We aimed to investigate factors associated with diet quality and the weight status of adolescents in Saudi Arabia. Methods: A cross-sectional study that included 638 healthy adolescents aged between 11 and 18 years who were randomly recruited from 16 private and public middle- and high-schools located in two Saudi cities (Jeddah and Madinah). All participants were given an envelope for parents to collect socioeconomic data. Diet quality and anthropometric data of adolescents were evaluated at school. Results: Median diet quality score was higher among males compared to female adolescents (10.00 (8.00-11.00) vs. 9.00 (8.00-10.0), respectively, p = 0.018). Median diet quality score was significantly higher among adolescents residing in Jeddah compared to adolescents residing in Madinah (10.00 (9.00-11.0) vs. 9.00 (8.00-10.0), respectively, p = 0.002). Stepwise linear regression analysis indicated that city of residence (B = -0.53, SE = 0.16 [95% CI: -0.83 to -0.22]), and child's sex (B = -0.34, SE = 0.15 [95% CI: -0.64 to -0.05]) were associated with diet quality scores of adolescents in Saudi Arabia. Discussion: Future longitudinal research should be directed to further investigate other possible factors influencing the diet quality of adolescents and individuals from other age groups in Saudi Arabia.

Diet plays an essential role in health and disease. Therefore, its determination is an important component of many investigations. The aim of the study was to evaluate the effect of a nutritional intervention on the urinary metabolome in children aged 6-12 years. Also, it was intended to identify biomarkers of diet quality and dietary intake. A 2-month, randomized, controlled, parallel trial was conducted in Spanish children. The analyses focused on the ALINFA group, which followed a full-fixed meal plan including healthy products, ready-to-eat meals, and healthy recipes. Diet quality was assessed by the KIDMED index and dietary intake by a food frequency questionnaire. Untargeted metabolomic analysis on urine samples was carried out, and multivariate analyses were performed for pattern recognition and characteristic metabolite identification. PLS-DA and Volcano plot analyses were performed to identify the discriminating metabolites of this group. 12 putative metabolites were found to be the most relevant to this intervention. Most of them were products derived from protein and amino acid metabolism (N-Ribosylhistidine, indolacrylic acid, and peptides) and lipid metabolism (3-oxo-2-pentylcyclopentane-1-hexanoic acid methyl, Suberoyl-L-carnitine, and 7-Dehydrodichapetalin E). All these metabolites decreased after the intervention, which was mainly associated with a decrease in the consumption of fatty meat and total fat, especially saturated fat. In turn, N-Ribosylhistidine and Suberoyl-L-carnitine were negatively associated with diet quality, as well as able to predict the change in KIDMED index. In conclusion, the changes observed in urinary metabolome demonstrate the effectiveness of the ALINFA nutritional intervention.
RESUMO
PURPOSE: Use qualitative and quantitative methods to explore factors influencing the adoption of guideline-based physical activity (PA) and dietary recommendations among participants enrolled in a lifestyle intervention during and after chemotherapy for breast cancer. METHODS: Among women with stage I-III breast cancer who participated in the intervention arm of the Lifestyle, Exercise, and Nutrition early after diagnosis (LEANer) trial, we used stratified, purposeful sampling to interview women who met both, one, or neither intervention goal after the 1-year intervention: (1) 150 min/week moderate-to-vigorous intensity exercise via a self-reported PA questionnaire and (2) improved self-reported diet quality measured by the Healthy Eating Index-2015. Semi-structured interviews were audio-recorded, transcribed verbatim, and analyzed using thematic content analysis. RESULTS: The 29 women interviewed were 52 ± 11 years old on average, with a mean body mass index of 29.6 ± 7.7 kg/m2. Three themes emerged regarding aspects of the LEANer intervention that facilitated behavior change: (1) providing a conduit of trustworthy, timely, and personalized support and education; (2) shifting mindsets and enhanced understanding of the benefits of PA and nutrition during chemotherapy; and (3) fostering a sense of control and alternative focus. Factors described as hindering adoption of goals included: (1) adverse effects of chemotherapy and (2) competing priorities. CONCLUSIONS: Women reported the external support, tailored education, and experiencing the physical and mental benefits of the LEANer intervention facilitated the adoption of the interventions' behavioral goals. Addressing chemotherapy-related symptoms and competing priorities may facilitate adherence to lifestyle interventions during chemotherapy for breast cancer.

OBJECTIVE: To explore the relationship between dietary quality and metabolic syndrome(MS) in the population aged 45 to 59 in Zhejiang Province. METHODS: Selecting the 45-59 year old population as the research object from the 2022 nutrition and health monitoring data of residents in Zhejiang Province. Dietary data was obtained by the 24-hour dietary review method on 3 consecutive days and the weighing method of household cooking oil and condiments, and dietary quality was evaluated using the China health diet index(CHDI), which was categorized into four groups according to quartiles of CHDI scores. Multivariate logistic regression model was used to analyze the relationship between different CHDI score groups and MS and its components. RESULTS: A total of 1421 study participants were included, with a mean CHDI score of(56.83±11.80) and a prevalence of MS of 24.5%. After adjusting for gender, age, smoking, and physical activity, the Q4 group with the highest CHDI score had a decreased risk of developing MS(OR=0.57, 95%CI 0.40-0.82), hypertension(OR=0.60, 95% CI 0.44-0.81), and elevated fasting blood glucose(OR=0.41, 95%CI 0.26-0.65) compared to the Q1 group with the lowest CHDI score. After conducting gender subgroup analysis, it was found that: the risk of developing MS, hypertension and high triglycerides was decreased in the Q4 group of CHDI scores in females compared with the Q1 group(P<0.05), whereas in males only high CHDI scores were found to be a protective factor for elevated fasting blood glucose(P<0.05). CONCLUSION: The quality of diet is negatively associated with the risk of MS, hypertension and hyperglycemia in people aged 45-59 years in Zhejiang Province, and there are gender differences in the relationship between CHDI and MS and its components.

This study aimed to investigate the change in diet quality in addition to dietary adherence to the planetary health diet during night shifts in healthcare workers. This observational follow-up study involved 450 healthcare workers working night shifts (327 females, 123 males). A survey form requesting sociodemographic information (gender, age, marital status), job title, sleeping duration during the night shift, 24 h dietary records for pre-night-shift, during night shift, and post-night-shift, and anthropometric measurements (body weight and height) was applied. The scores of the Planetary Health Diet Index (PHDI) and the Healthy Eating Index 2020 (HEI-2020) were calculated according to the dietary records. The total HEI-2020 and PHDI scores decreased significantly (p < 0.05) during the night shift (44.0 ± 8.8 and 48.3 ± 13.2, respectively) compared to pre-night-shift (46.1 ± 9.2 and 51.9 ± 13.4, respectively) and increased post-night-shift (44.7 ± 9.9 and 50.6 ± 14.9, respectively), with no statistically significant difference between pre- and post-night-shift. There was a significant main effect of night shift working on total PHDI (F(896, 2) = 8.208, p < 0.001, ηp2 = 0.018) and HEI-2020 scores (F(894, 2) = 6.277, p = 0.002, ηp2 = 0.014). Despite healthcare workers' knowledge of health factors, night shifts lead to poor dietary choices. To improve diet quality and sustainability, it is crucial to enhance access to healthy food options in their work environment.

OBJECTIVES: We hypothesized that a low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet may be associated with the disease severity of ulcerative colitis (UC). Therefore, this cross-sectional study was undertaken to assess the association between FODMAP score and UC severity. METHODS: In this study, 158 patients with UC were enrolled. The disease severity was designated using the Mayo score. The diet relation information was obtained using the 160-item food frequency questionnaire. To calculate the FODMAP score, the consumption of all food items was converted to a gram per day and multiplied by the FODMAP factor. The FODMAP factor was obtained from the application developed by Monash University (Melbourne, Victoria, Australia). The association between disease severity (dependent factor) and FODMAP score tertiles (independent factors) was assessed by logistic regression adjusted for different covariates. RESULTS: In the present study, the age range of participants was 18 to 64 y old, and 46.2% of patients had moderate or severe disease activity. There were significant differences in sex, body mass index, and supplement use across different tertiles of FODMAP score. There was no significant association between the FODMAP score tertiles and disease severity in the crude model and adjusted models. CONCLUSIONS: The results of the present study showed that there was no significant association between the FODMAP score and UC severity. However, considering the limitations of the study, more studies with prospective and interventional designs using more accurate methods of dietary assessments are needed to confirm these preliminary results.
RESUMO
Objective: To examine geographic disparities in the nutritional quality of food purchases during the COVID-19 public health crisis in North Carolina (NC). Methods: Using shopper-level longitudinal transaction records between October 2019- and December 2020 from NC's largest grocery retailer, we fit mixed-effect models to examine disparities in the nutritional quality of food purchases among shoppers in counties with different levels of socioeconomic development and how such disparities changed after March 2020, accounting for other observed and contextual factors. Results: Shoppers in counties with lower development levels purchased a larger share of calories from least healthy foods and a smaller share from healthier foods compared to shoppers in counties with higher development levels. These disparities were slightly attenuated for the least healthy foods and did not change for healthier foods after the onset of the COVID crisis. Conclusion: Despite existing nutritional disparities among shoppers in counties with different levels of socioeconomic development, we did not observe a large-scale accentuation of inequities in dietary quality during the COVID-19 crisis. This pattern may have resulted from programmatic responses to mitigate the adverse effects of the COVID crisis on vulnerable populations. Future work should further explore the role of such responses.
RESUMO
BACKGROUND: Depression is a common mental health disorder. OBJECTIVE: The objective of this study was to explore the association between diet quality, as measured by the Healthy Eating Index (HEI-2020), and depression symptoms among US adolescents and young adults, 12-29 years. DESIGN: The study design was a cross sectional secondary data analysis. PARTICIPANTS: Data from the first 24-hour dietary recall for adolescents and young adults 12-29 years in the National Health and Nutrition Examination Survey 2015-March 2020 (n=4750) were analyzed. MAIN OUTCOME: Depression was defined as a score ≥10 from the Patient Health Questionnaire reflecting moderate or severe symptoms in the previous 2 weeks. STATISTICAL ANALYSES PERFORMED: HEI-2020 total (range 0-100) and component scores were calculated for those with and without depression. Predicted HEI-2020 scores were estimated from linear regression models, adjusting for age, gender, race and Hispanic origin, family income, and seeing a mental health professional in the past year. Statistical analyses accounted for the complex sample design. RESULTS: The prevalence of depression among adolescents and young adults was 7.8% (95% confidence interval (CI) 6.3-9.5%). Total HEI-2020 score was 45.9 (95% CI 45.0-46.7) out of 100 on a given day during 2015-March 2020. Among young people with depression, total HEI-2020 score was lower than among those without depression (41.7 versus 46.2, p<0.001). After adjustment for covariates, the difference was attenuated but remained significant. In adjusted analyses, HEI-2020 component scores were lower for those with depression compared to those without depression for the adequacy components: Total Fruits (1.4 vs. 1.7 p=0.03), Whole Fruits (1.2 vs. 1.7 p<0.01), Total Vegetables (2.1 vs. 2.6 p<0.01), Greens and Beans (0.8 vs. 1.2 p<0.01), and Total Protein foods (3.6 vs. 4.0 p=0.02) out of maximum scores of 5. There were no statistically significant differences observed for Whole Grains, Dairy, Seafood and Plant Proteins, Fatty Acids, Saturated Fats, Refined Grains, Sodium, or Added Sugars. CONCLUSION: Overall diet quality is low among young people. Diet quality, especially consumption of fruits, vegetables, and protein foods was lower among young people with depression compared to those without depression.
RESUMO
OBJECTIVE: The aim was to examine the association between social frailty and diet quality in adults over 65 years of age, and whether results differed by sex. DESIGN: Population-based cross-sectional study using data from the Spanish National Health Survey. PARTICIPANTS: 5,071 community-dwelling people ≥65 years from Spain. MEASUREMENTS: Social frailty was deemed to exist when the person both lived alone and had low social support, measured with the Duke-UNC scale. Diet was assessed with the Spanish Healthy Eating Index (S-HEI), ranging from 0 to 100 points (highest diet quality). Means and 95% confidence intervals of the S-HEI score for each social frailty group were calculated using linear regressions, with socially robust people as reference. Analyses were adjusted for main confounders, including sociodemographic, lifestyle and morbidity variables. RESULTS: There were no differences in the S-HEI adjusted mean of socially frail (74.3 points, 95%CI: 73.4-75.2) compared to socially robust older adults (75.4 points; 95%CI: 75.1-75.7). In sex-stratified analyses, the S-HEI adjusted mean of socially frail men (71.9 points; 95%CI: 70.6-73.2) was lower than robust men (74.8 points; 95%CI: 74.4-75.3). Specifically, social frailty was associated with lower consumption of vegetables, fruits, dairy and lower diet variety in men. Differences were not observed according to social frailty among older women. CONCLUSIONS: Social frailty was associated with poor diet quality in community-dwelling older men, but not in women in Spain. Gender differences in self-care could partly explain this association. Sex-specific interventions are required to minimize the impact of social frailty on diet quality.
RESUMO
In Canada, unhealthy dietary patterns comprise diets with poor nutrient density and are associated with chronic conditions. Plant-based diets have gained popularity due to their ability to provide a nutritionally adequate healthy diet. This study aims to compare sociodemographic, socioeconomic, and health characteristics, and diet quality between Canadian adults following plant-based and omnivore diets as well as assess the extent to which key nutrient intakes are of public health concern among Canadians following plant-based diets. The study used nationally representative nutritional data from the 2015 Canadian Community Health Survey and descriptive statistics were computed. The analysis determined that Canadians following strict plant-based diets (1% of total population) were significantly more likely to be an immigrant to Canada, less likely to meet national physical activity guidelines, and less likely to be overweight, compared to Canadians following omnivore diets. Compared to omnivore diets, plant-based diets were nutritionally superior according to the Nutrient-Rich Food index. Continued knowledge translation on what comprises healthy plant-based diets, public guidance on the intersection between diet and health, and the completion of prospective cohort studies are needed. To conclude, the research suggests well-planned plant-based diets, in comparison to omnivore diets, offer a nutrient-dense diet.

The main objective of this study was to examine the actor and partner effects between Perceived Workplace Support for Families (PWSFs) and family support (PFS), diet quality, and satisfaction with food-related life (SWFoL) in households with both parents working and adolescents, along with the role of the three family members' diet quality as a mediator. During the second year of the pandemic in Chile, 860 dual-earner parents of different sexes and their adolescent child (average age 13 years, with 50.7% being male) were recruited from two cities. Parents responded to a measure of PWSFs and the Perceived Family Support Scale. Mothers, fathers, and adolescents answered the Adapted Healthy Eating Index (AHEI) and the satisfaction with food-related life Scale. The examination employed the mediation Actor-Partner Interdependence Model and structural equation modeling for the analyses. Results showed that mothers' PWSFs improved their and their teenage children's SWFoL, while fathers' PWSFs only improved their SWFoL. The mothers' PFS improved their and the fathers' diet quality while enhancing their SWFoL and the adolescents' SWFoL. The fathers' PFS enhanced their and the adolescents' SWFoL. The mothers' PFS also indirectly enhanced their and the fathers' SWFoL via each parent's diet quality. Each family member's diet quality was positively related to their SWFoL, while mothers' diet quality was positively related to the fathers' SWFoL. These results imply that resources obtained by parents from PFS positively impact the SWFoL of the three family members through different mechanisms. They also highlight the importance of maternal family support for SWFoL during the pandemic.

(1) Background: Although daily time-use is associated with diet quality and cardiorespiratory fitness (CRF) in children, their interdependence remains unexplored. This study first examined the associations between reallocating daily movement time and diet quality and CRF, and second the mediating role of diet quality in the relationship between daily time-use and CRF. (2) Methods: This study included 1131 Chinese children (aged 8 to 10 years; median [interquartile range]: 8.5 [8.3, 8.8]) at baseline (September 2022) and 1268 children at the 9-month follow-up (June 2023) from the OptiChild study. Daily durations of moderate-to-vigorous physical activity (MVPA), sleep, and sedentary behavior (e.g., screen time) were self-reported or proxy-reported by parents. Diet quality was assessed via the Diet Quality Questionnaire (DQQ), which uses a 24 h dietary recall and is categorized according to the Global Dietary Recommendations (GDR) score and Food Group Diversity Score (FGDS). The CRF was measured using VO2max after the 20 m shuttle run test. Longitudinal associations between daily time-use, diet quality, and CRF were calculated using isotemporal substitution models. Mediation analyses were used to determine whether diet quality mediated the associations between daily time-use and CRF. (3) Results: Reallocation of 30 min from screen time to MVPA resulted in significant improvements in the GDR score (ß baseline = 0.11, p = 0.024; ß follow-up = 0.26, p < 0.001), FGDS (ß baseline = 0.11, p = 0.006; ß follow-up = 0.19, p < 0.001), and CRF (ß baseline = 0.40, p < 0.001; ß follow-up = 0.26, p = 0.001). Diet quality partially mediated the associations between MVPA, screen time, and CRF. Substituting 30 min of screen time for MVPA led to diet quality mediating a proportion of the association with CRF (GDR score: 11.4%, FGDS: 6.6%). (4) Conclusions: These findings underscore the importance of optimizing daily time-use of MVPA and screen time and improving diet quality to promote physical fitness in school-aged children.

Recent studies suggest that shift working may trigger health issues through disrupted circadian rhythms and altered eating habits. This study aimed to examine the possible associations of shift work with sleep quality, diet quality and obesity-related parameters. This study was conducted with 150 males (75 shift and daytime workers) aged 24-50 years. Dietary intake was determined using the 24-hour recall method, and dietary quality was evaluated using the Healthy Eating Index-2010 (HEI-2010). Anthropometrical measurements and body composition were assessed. The Pittsburgh Sleep Quality Index was used to evaluate sleep quality. Fasting and postprandial glucose and insulin, and fasting lipid levels were analyzed. HOMA-IR was calculated, and blood pressure was measured. The total HEI-2010 score of shift workers (52.6 [45.4-58.8]) was lower than the daytime workers (55.9 [49.1-64.9]) (p = 0.016). Among individuals with good sleep quality, the total HEI-2010 score, seafood and plant proteins, fatty acids, and sodium scores were lower in shift workers compared to others (p < 0.05 for each). Non-obese shift workers had higher body weight, waist circumference, waist/hip ratio, VLDL-cholesterol, triglyceride, postprandial glucose, and insulin levels compared to daytime workers (p < 0.05 for each). This study demonstrates that shift working is associated with lower diet quality independent of sleep quality.
RESUMO
BACKGROUND: Child diet can impact risk for obesity and other related noncommunicable diseases. Few studies have used the Healthy Eating Index (HEI)-Toddlers-2020 to assess diet quality among toddlers (children aged 12-23.9 months). OBJECTIVE: The aim of this study was to examine diet quality among toddlers participating in the Feeding Infants and Toddlers Study (FITS), 2016 and determine differences by sociodemographic characteristics. Caregiver perception of how their toddler's diet aligns with HEI-Toddlers-2020 diet quality scores was also assessed. DESIGN: This cross-sectional study used 24-hour dietary records collected in 2016. PARTICIPANTS/SETTING: Data were collected on 12- to 23.9-month-old toddlers (n = 1,133) participating in the FITS 2016. MAIN OUTCOME MEASURE: Diet quality was assessed using the HEI-Toddlers-2020. STATISTICAL ANALYSES PERFORMED: The population ratio method was used for all analyses using weighted data to estimate HEI-Toddlers-2020 scores overall and within subgroups. To determine significant differences of the HEI-Toddlers-2020 score between subgroups, pairwise t-tests were used. Statistical significance at p<.05 was used as a cutoff for all two sided p-values. RESULTS: Average HEI-Toddlers-2020 score among 12-23.9-month-olds participating in FITS 2016 was 71.2 out of a possible 100. Total scores varied by race and ethnicity with Hispanic toddlers having higher scores compared to non-Hispanic White toddlers (76.4 (2.5) vs. 69.0 (1.2), p=.03) and by federal poverty level with those >200% of the poverty level having higher scores compared to those <100% of the poverty level (74.7 (1.5) vs. 67.0 (2.6), p=.01). CONCLUSIONS: Opportunities for improvement in dietary intake were identified using the new HEI-Toddlers-2020 to assess diet quality among 12-23.9-month-olds. Scores were indicative of toddlers consuming excess added sugars and lower than recommended amounts of seafood and plant proteins, greens and beans, whole grains, and vegetables. Interventions to improve diet quality in toddlers may benefit from focusing on foods children should eat more of along with foods to consume in moderation.
RESUMO
BACKGROUND & AIMS: The double burden of malnutrition compels us to reconsider macronutrients from a diet quality perspective. The Macronutrient Quality Index (MQI) has been designed to reflect overall macronutrient quality and is based on three sub-indexes: the carbohydrate quality index (CQI), the healthy plate protein quality index (HPPQI) and the fat quality index (FQI). Nutritional adequacy is an essential aspect of diet quality that should be captured by reliable dietary indexes. METHODS: We analyzed the association between the Macronutrient Quality Index (MQI) and micronutrient adequacy. Participants were children aged 4 and 5 years, recruited in the SENDO cohort. Baseline information was collected through a self-administered online questionnaire, which included information on sociodemographic, dietary, and lifestyle variables. Dietary information was obtained using a 147-item validated semi-quantitative food frequency questionnaire. Participants were categorized into tertiles based on their MQI score. We evaluated the intake of 20 micronutrients and assessed the probability of micronutrient adequacy using the Estimated Average Requirement cut-off point. RESULTS: Children in the highest tertile of MQI had 0.33-fold lower odds (95%CI 0.17-0.66) of having ≥3 inadequate micronutrient intakes than their peers in the lowest tertile, after adjusting for potential confounders. The adjusted proportions of children with inadequate intake of ≥3 micronutrients were 18%, 14% and 11% in the first, second, and third tertiles of MQI respectively. The MQI appears to be capable of capturing nutrient adequacy in children, although our results suggest that a modified MQI, with eggs and dairy products weighted positively, might be more adequate for the pediatric population.
RESUMO
BACKGROUND: Limited information exists linking food habits, diet quality, and lifestyle scores with anthropometric indices and happiness levels. Our aim was to examine the association between food habits, diet quality, and lifestyle scores with anthropometric indices and happiness levels in the Iranian population. METHODS: This cross-sectional study included 200 students randomly selected from a university in Iran. Dietary intakes, physical activity (PA), and happiness levels of study participants were assessed using validated questionnaires. The anthropometric indices examined in this study included the body shape index (ABSI), body roundness index (BRI), and abdominal volume index (AVI). Multiple logistic regression models were used to examine the association between food habits, diet quality, and lifestyle scores with anthropometric indices and happiness levels. RESULTS: The mean age and body mass index (BMI) of study participants were 23.5 years ± 4.52 and 23.8 kg/m2 ± 3.17, respectively. In the study population, no significant association was seen between ABSI, BRI, AVI and happiness with food habits, diet quality, and lifestyle scores respectively. After adjusting for potential confounders (age, energy intake, marital status, education, smoking, physical activity, gender, and BMI), the association remained not significant for ABSI and food habits, diet quality, and lifestyle scores respectively (OR: 0.56, 95% CI (0.25-1.34), P = 0.193; OR: 0.59, 95% CI (0.22-1.57), P = 0.413; OR:1.19, 95%CI (0.54-2.63), P = 0.652), BRI and food habits, diet quality, and lifestyle scores respectively (OR:1.98, 95% CI (0.41-9.49), P = 0.381; OR: 0.57, 95%CI (0.12-2.74), P = 0.512; OR: 1.19, 95% CI (0.3-4.71), P = 0.811), AVI and food habits, diet quality, and lifestyle scores (OR:1.15, 95% CI (0.53-2.48), P = 0.743, OR:1.01, 95% CI (0.47-2.18), P = 0.965; OR: 1.3, 95% CI (0.64-2.65), P = 0.465) and happiness and food habits, diet quality, and lifestyle scores respectively (OR:0.3, 95%CI (0.07-1.25), P = 0.972; OR: 0.77, 95%CI (0.18-3.19), P = 0.724, OR: 0.3, 95% CI (0.07-1.25), P = 0.083). CONCLUSIONS: No significant association was detected between food habits, diet quality, and lifestyle scores with anthropometric indices and happiness levels. However, longitudinal studies are required to confirm these findings.
RESUMO
Background: Various food quality indicators have been proposed as tools for predicting metabolic syndrome (MetS). This study investigated the association between global diet quality score (GDQS) and the risks of developing MetS and its components. Methods: In this secondary analysis, we included elective adult participants (n=4,548) from the Tehran Lipid and Glucose Study. Dietary data were collected by a valid and reliable semi-quantitative food frequency questionnaire. MetS was defined according to the Iranian modified National Cholesterol Education Program. Multivariable Cox proportional hazard regression models were used to estimate the incidence of MetS in association with GDQS. Results: This study involved 1,762 men and 2,786 women with a mean±standard deviation age of 38.6±14.3 and 35.9±11.8 years, respectively. A total of 1,279 subjects developed MetS during the mean follow-up of 6.23 years. Incidence of MetS was associated with GDQS (hazard ratio [HR], 1; 0.90 [95% confidence interval, CI, 0.82 to 0.98]; 0.84 [95% CI, 0.76 to 0.91]; 0.80 [95% CI, 0.73 to 0.89]; P for trend <0.001) after adjusting for confounding variables. The healthy food group component of GDQS was related to MetS incidence. GDQS in the range of 12%-17% in the fourth quartile was associated with a decrease in incidence of MetS components. Both healthy and unhealthy food group components of the GDQS decreased the incidence of high triglycerides, high blood pressure, and high fasting blood glucose. Conclusion: Higher GDQS was associated with a lower risk of the incidence of MetS or its components among Tehranian adults. Higher intake of healthy food group components and lower consumption of unhealthy food group components of the GDQS predicted lower MetS incidence and risk factors.
RESUMO
Childhood eating behaviors are associated with weight status and laboratory assessments of dietary intake. However, little is known about how eating behaviors relate to the eating patterns and diet quality of children from marginalized populations when assessed in their natural environments. Therefore, we examined the association of food avoidant (e.g., food fussiness and satiety responsiveness) and food approach (e.g., food responsiveness and enjoyment of food) eating behaviors with children's meal size, eating frequency, and diet quality. We analyzed data from 61 predominately low-income Hispanic/Latinx preschool-aged children. Caregivers completed the Childhood Eating Behavior Questionnaire and two 24-h dietary recalls. From the recalls, we calculated meal size, eating frequency, and modified Diet Quality Index Scores (DQIS), and evaluated associations with eating behaviors using multivariable linear models. We also explored the relationship between eating behaviors and DQIS components. Food-avoidant subscales were associated with smaller meals and satiety responsiveness were associated with decreased snack frequency. Food approach subscales were not associated with meal size or eating frequency. Both food-avoidant and food-approach behaviors were associated with components of diet quality and caloric beverages outside of meal and snacks. These findings can inform future research on the relationship between child eating behaviors and dietary intake so that we can develop more tailored and effective interventions to promote healthy eating habits for low-income, Hispanic/Latinx preschool-aged children.
