Type and timing of ultra-processed foods consumption and its association with dietary intake and physical activity in women with obesity living in poverty.

BACKGROUND: The present study aimed to investigate the type and timing of ultra-processed foods (UPF) consumption and its association with dietary intake (DI) and physical activity (PA) in women with obesity living in poverty. METHODS: A cross-sectional study was employed. Obesity was defined by at least two criteria (body mass index, waist circumference or % fat mass). Poverty was defined as the three lowest classes of the Brazilian Economic Classification Criterion. PA was measured with triaxial accelerometers and DI was assessed with three 24-h dietary recalls. Foods were categorised according to the NOVA classification, with UPF classified into five subgroups, as well as the timing of consumption into six meals. RESULTS: In total, 56 adult women were included. Overall energy intake was 1653.21 (503.22) kcal/day. UPF intake was 21.62% (11.94%) kcal/day, being higher at breakfast (4.91% kcal/day), afternoon snack (5.39% kcal/day) and dinner (5.01% kcal/day). Only UPF subgroup 4 (sandwich biscuits, sweets, or treats) showed a positive association with energy intake (ß = 54.40 [27.6, 81.10] kcal/day) and a negative association with protein intake (ß = -0.31% [-0.48%, -0.14%] kcal/day). UPF consumption in morning (ß = -0.41% [-0.79%, -0.02%] kcal/day) and afternoon (ß = -0.18% [-0.33%, -0.04%] kcal/day) snacks was associated with lower protein intake. Furthermore, lunchtime UPF consumption was positively associated with walking time (ß = 0.16% [0.02%; 0.30%]) and steps/hour (ß = 8.72 [1.50; 15.94] steps/h). CONCLUSIONS: Women with obesity living in poverty consume more UPF during breakfast, afternoon snack and dinner. Physical activity is positively associated with UPF consumption at lunch. UPF, such as sandwich biscuits, sweets or treats, contribute to increasing energy intake and reducing protein intake.

The Double Burden of Malnutrition is Associated with Continued Breastfeeding and Early Consumption of Ultra-Processed Drinks in Socially Vulnerable Brazilian Children.

This study aimed to assess the association between the double burden of malnutrition (DBM) with continued breastfeeding and the early introduction of ultra-processed drinks in children living in situations of social vulnerability. This cross-sectional population-based study was carried out in a capital city in the Northeast of Brazil, which included 561 children. It was observed that introducing soft drinks into the child's diet during the first year of life was directly associated with DBM but indirectly with continuous breastfeeding for 12 or more months. These results indicate paths that can be followed to reverse the current scenario.

Type 2 diabetes mellitus is associated with food addiction in Brazilian women living in poverty.

Food addiction (FA) has been widely investigated. For the first time, two studies reported its association with type 2 diabetes mellitus (DM2) in the general population and populations with mental disorders and undergoing bariatric surgery. However, the relationship between FA and DM2 needs to be better explored in different social contexts and population groups. Given this, the present study aims to evaluate whether DM2 diagnosis is associated with FA diagnosis in women living in poverty. This is a cross-sectional, population-based study conducted in a Brazilian capital city. FA was assessed by the modified Yale Food Addiction Scale (mYFAS) 2.0, and DM2 diagnosis was assessed by self-reporting of previous medical diagnosis. The association was assessed by multivariable Poisson regression with robust variance estimation adjusted for age, poverty situation, race/skin colour, physical activity and BMI. A total of 1878 women were included, of whom 15·1 % had FA and 3·2 % had a medical diagnosis of DM2. In the multivariable analysis, the medical diagnosis of DM2 was associated with FA (prevalence ratio, PR: 2·18; 95 % CI (1·26, 3·76)). The DM2 diagnosis was also identified to be associated with role interference (PR: 1·93; 95 % CI (1·01, 3·67)) symptom of FA. In conclusion, a positive association between FA and DM2 in women living in poverty was observed, information that adds to the current evidence already available in the literature, pointing to a new line of research and integrated care.

Early introduction of ultra-processed foods is associated with overweight and anaemia in socially vulnerable Brazilian children.

This study aimed to evaluate the early introduction of ultra-processed foods (UPF) and identify its association with overweight and anaemia in Brazilian children living in a situation of social vulnerability. A population-based cross-sectional study was conducted in a Brazilian capital. Children aged 12-59 months were included. The presence of overweight and anaemia was evaluated, as well as the introduction of twelve different UPF in children's first year of life. Association analysis was performed using Poisson regression, with robust estimates of variances. A total of 561 children were studied; 85·5 % had consumed at least one UPF evaluated in the first year of life; 19·1 % were overweight and 52·0 % were anaemic. Adjusted multivariate analyses identified that the early introduction of soft drinks (Prevalence Ratio (PR) = 1·18, 95 % CI (1·02, 1·38)), packaged snacks (PR = 1·17, 95 % CI (1·05, 1·30)) and powdered soft drinks (PR = 1·36, 95 % CI (1·16, 1·60)) increased the likelihood of children being overweight, and the early introduction of chocolate drink (PR = 1·25, 95 % CI (1·02, 1·53)) increased the likelihood of them being anaemic, when comparing children who consumed these UPF before reaching 1 year of age with those who consumed these foods at 12 months of age or older. From the results found, one can see the existing relationship between the early introduction of UPF with overweight and anaemia, being necessary to intensify public health policies to combat malnutrition, focusing on the promotion of proper and healthy eating, especially during the phase of food introduction, focusing on the population living in socially vulnerable situations.

Longitudinal estimates of resting energy expenditure using predictive equations in individuals with excess weight after weight loss: A systematic review with meta-analysis.

BACKGROUND & AIMS: To determine which resting energy expenditure (REE) predictive equation has the lowest bias in the aggregate level in individuals with excess weight during weight loss interventions. METHODS: Searches were performed in MEDLINE, Web of Science, Scopus, CENTRAL and gray literature databases. Longitudinal studies on weight loss interventions which evaluated REE by predictive equations compared to that measured by indirect calorimetry in adults with excess weight at different follow-up times were included. Meta-analyses were performed with the differences between biases of predictive equations of the REE at the different follow-up times of weight loss. RESULTS: Of the total of 2178 occurrences found in the databases, only eight studies were included. The Harris-Benedict (1919) equation showed the smallest differences between bias up to the third month (MD = 103.33 kcal; 95%CI = -39.01; 245.67), in the sixth month (MD = 59.16 kcal; 95%CI = 8.74; 109.57) and at the 12th month (MD = -71.41 kcal; 95%CI = -150.38; 7.55) of weight loss follow-up. Weight loss does not seem to have an effect on bias at different follow-up times. CONCLUSION: Harris-Benedict (1919) equation seems to be the most adequate to assess the REE of individuals with excess weight during weight loss. However, the finding of large estimated predictive intervals may indicate that predictive equations may not be handy tools for individuals losing and regaining weight due to changes other than body weight.

Effects of SARS-CoV-2 infection on health and functional capacity in institutionalized older adults.

OBJECTIVE: To assess the effect of SARS-CoV-2 infection on the health conditions and functional capacity of older adults living in long-term care units in Maceió City - Alagoas State. METHODS: A prospective cohort was conducted with institutionalized older adults of both sexes. Older adults were assessed for clinical conditions (diagnosis of chronic diseases and biochemical tests), functional capacity, and nutritional status. All assessments were repeated on two occasions, maintaining a 6-month interval between them. RESULTS: The sample was composed of 289 older adults. Of the total, 98 (33.9%) were positive for COVID-19 and eight died (2.8%). Men were more likely to have COVID-19 (OR = 3.50; p < 0.01). It was observed that the disease contributed to increasing the frequency of dependent older adults after six months (OR = 1.38; p-interaction < 0.01). It was also observed that after six months of positive diagnosis for COVID-19, there was greater weight loss (p < 0.01), reduced BMI (p < 0.01), increased mean SBP (p = 0.04), and DBP (p = 0.03). CONCLUSION: Effects of COVID-19 in institutionalized older adults go beyond acute complications and compromise blood pressure control, functional capacity, and favor weight loss.

Adequacy of the "pocket formulas" for measuring total energy expenditure in healthy women compared with the new DRI equation: A doubly labeled water study.

OBJECTIVES: "Pocket formulas" are practical alternatives for calculating an individual's total energy expenditure (TEE). Typically, more sophisticated predictive equations are used, such as the new equations proposed in the Dietary Reference Intakes (DRI). Nevertheless, these new equations necessitate estimating physical activity levels (PALs). The aim of this study was to compare the use of pocket formulas (kcal/kg of body weight) with the new predictive equations for energy expenditure proposed by the DRI (2023) in healthy women and with the doubly labeled water (DLW) method to predict TEE. METHODS: The TEEs of healthy adult women were measured by DLW and calculated using the pocket formulas (× 20, × 25, × 30, and × 35 kcal/kg of body weight) and the new DRI equation. PALs by triaxial accelerometers were also collected. RESULTS: The study included 55 women. For the entire sample, the × 30 pocket formula had the lowest bias (-6%; limits of agreement [LOAs]: -39.8; 27.5; root mean square error: 373.4) and the highest precision (42%). The pocket formulas showed reasonable agreement in the different body mass index categories compared with the results found by the 2023 DRI proposal. For individuals with normal weight, the agreement was × 35 kcal/kg: bias (%) = -4.8; LoA = -41.5; 31.8, with overweight, it was × 30 kcal/kg: bias (%) = -2.2; LoA = -25.1; 20.6, and with obesity, it was × 30 kcal/kg: bias (%) = 4.2; LoA = -21.1; 29.4. CONCLUSION: Pocket formulas provide a reasonable agreement with TEE in healthy, sedentary, or low-active adult women, which may be a more simplistic strategy when there is no PAL data for calculating the DRI equations.

Use of the activPAL® triaxial accelerometer to estimate total energy expenditure in low-income women: differences between body mass index classifications.

Objective: This study aimed to assess the agreement between the total energy expenditure (TEE) estimated by the activPAL® triaxial accelerometers (ACC) and the TEE measured by the doubly labeled water method (DLW), as well as to assess if these values differ between the classifications of body mass index (BMI). Materials and methods: This is a cross-sectional study. Low-income adult women (19-45y) with BMI ≥ 18.5 kg/m2 were included. Accelerometry data (activPAL® ) were collected over 7 consecutive days, which were used to calculate TEE-ACC and compared with DLW data. The Bland-Altman method, concordance correlation coefficient and root mean square error were used to assess agreement between methods. Results: The sample consisted of 55 women with a mean age of 31 ± 5 years. The agreement between TEE-ACC and TEE-DLW showed a bias of -142.5 kcal (-7.1%). Among the BMI classifications, participants with normal weight show a bias of -417.1 kcal (-21.0%), participants with overweight, -87.5 kcal (-3.9%) and participants with obesity, 97.5 kcal (4.3%). Furthermore, the bias between the methods showed a significant and positive correlation with the body weight (r = 0.49; p < 0.01). Conclusion: The TEE-ACC estimates from activPAL® were reasonably accurate when compared to the TEE-DLW, especially in women with overweight and obesity, being much less accurate in individuals with normal weight.

Commentary on "Food addiction, orthorexia nervosa and dietary diversity among Bangladeshi university students: a large online survey during the COVID-19 pandemic".

The food addiction construct is receiving increasing attention from researchers and clinicians worldwide. Given its rise, scientific production on the subject is increasingly abundant. Conducting studies evaluating food addiction in emerging countries is of great importance, given that most scientific production comes from high-income countries. A recent study aimed to explore the prevalences of orthorexia nervosa and food addiction and their associations with dietary diversity in university students in Bangladesh during the COVID-19 pandemic. This correspondence presents questions about using the older version of the modified Yale Food Addiction Scale to assess food addiction. It also highlights issues related to the prevalence of food addiction observed in the study.

Association between food addiction with ultra-processed food consumption and eating patterns in a Brazilian sample.

The study objectives were to determine whether consumption of ultra-processed foods (UPF) and eating patterns are associated with food addiction (FA) in a Brazilian sample. This is a cross-sectional study. The Brazilian Food and Nutrition Surveillance System tool assessed food consumption markers and dietary patterns. The modified Yale Food Addiction Scale 2.0 was used to determine FA. 5946 participants were included with a mean age of 24 ± 6 years, and 4371 (73.5%) were female. After statistical adjustments for confounders, individuals with FA had lower consumption of fresh fruits (PR: 0.88; 95%CI: [0.79; 0.97]), vegetables (PR: 0.87; 95%CI: [0.79; 0.97]), and beans (PR: 0.85; 95%CI: [0.77; 0.95]). They also had higher consumption of UPF: hamburgers/sausages (PR: 1.15; 95%CI: [1.04; 1.27]), instant noodles, packaged snacks, and/or salty cookies (PR: 1.27; 95%CI: [1.13; 1.42]), and sandwich cookies, sweets, and/or treats (PR: 1.26; 95%CI: [1.14; 1.40]). Positive associations between FA and having meals in front of the screen (PR: 1.48; 95%CI: [1.28; 1.71]) and having a late-night snack (PR: 1.24; 95%CI: [1.11; 1.39]) remained. The negative association between FA and skipping breakfast (PR: 0.76; 95%CI: [0.68; 0.85]) also remained. These eating patterns may contribute to FA, which could be potential targets for clinical intervention.

Estimation of the availability of iron in the school meals of Municipal Centers for Early Childhood Education of a capital city in northeastern Brazil.

The final stage of Fe deficiency is Fe deficiency anaemia, with repercussions for human health, especially in children under 5 years of age. Studies conducted in Brazilian public daycare centres show high prevalence of anaemia. The present study aims to evaluate the availability of Fe in the meals of the Municipal Centers of Early Childhood Education in Maceió. The experimental design comprises selection of algorithms, menu evaluation, calculation of the estimates, comparison between the estimates obtained and the recommendations, and analysis of correlation between meal constituents, and of the concordance between the absorbable Fe estimates. Four algorithms were selected and a monthly menu consisting of 22 d. The correlation analysis showed a moderate positive correlation to animal tissue (AT) v. non-heme iron (r = 0·42; P = 0·04), and negative to AT v. Ca (r = -0·54; P = 0·09) and Ca v. phytates (r = -0·46, P = 0·03). Estimates of absorbable Fe ranged from 0·23 to 0·44 mg/d. The amount of Fe available, unlike the total amount of Fe offered, does not meet the nutritional recommendations on most school days. The Bland-Altman analysis indicated that the Monsen and Balinfty and Rickard et al. showed greater agreement. The results confirm the need to adopt strategies to increase the availability of Fe in school meals.

[Assessment of food insecurity in the context of COVID-19: association with emergency aid and collecting food donations among the socially vulnerable population of a capital in Northeastern Brazil]. / Avaliação da insegurança alimentar no contexto da COVID-19: associação com o auxílio emergencial e recebimento de doação de alimentos na população em vulnerabilidade social de uma capital do Nordeste do Brasil.

The scope of this study was to investigate the prevalence of food insecurity in the context of COVID-19 and its association with the emergency aid income-transfer program and the collecting of food donations by the population in a situation of social vulnerability. A cross-sectional study was carried out with socially vulnerable families eight months after confirming the first case of COVID-19 in Brazil. A total of 903 families, living in 22 underprivileged communities of Maceió, in the state of Alagoas, were included. Sociodemographic characteristics were evaluated, and the Brazilian Food Insecurity Scale was applied. The association of food insecurity with the variables studied was performed using Poisson regression with robust variance estimation, considering α = 5%. Of the total sample, 71.1% were food insecure, a situation associated with receiving food donations (PR = 1.14; 95%CI: 1.02; 1.27) and being a beneficiary of emergency aid (PR =1.23; 95%CI: 1.01; 1.49). The results show that the population in a situation of social vulnerability was strongly affected by food insecurity. On the other hand, the population group in question benefited from actions implemented at the outset of the pandemic.

Do total da amostra, 71,1% estavma em insegurança alimentar, situação que se associou com o recebimento de doação de alimentos (RP = 1,14, IC95%: 1,02; 1,27) e ser beneficiário do Auxílio Emergencial (RP = 1,23, IC95%: 1,01; 1,49). Os resultados mostram que a população em vulnerabilidade social foi fortemente afetada pela insegurança alimentar. Em contrapartida, essa população foi beneficiada por ações que foram implementadas no início da pandemia.

Food frequency questionnaires developed and validated for pregnant women: Systematic review.

OBJECTIVES: Assessing food intake of pregnant women is extremely important, because maternal dietary patterns can influence fetal development as well as have either positive or negative effects on both the mother and fetus. Thus, the aim of the present study was to carry out a systematic review of the literature on food frequency questionnaires developed and validated for pregnant women, in order to assess their methodological quality and validation process. METHODS: A systematic review of studies focused on validating food frequency questionnaires for pregnant women was carried out in the PubMed, Embase, Scopus, LILACS, and OpenGrey databases. The selected studies were assessed based on their correlation coefficient in validation and reproducibility analyses, whereas their methodological quality was assessed based on the scoring system proposed by the EURopean micronutrient RECommendations Aligned Network of Excellence. RESULTS: In total, 10 965 articles were identified in these databases; among them, 14 studies, with sample sizes ranging from 46 to 221 participants, and with participants (pregnant women) at a mean age of 28.68 ± 4.34 y, were selected. Most of the included studies used the 24-h food recall as the method for developing the food list (n = 6), with composition ranging from 46 to 255 items. With respect to the methodological assessment of the selected articles, half of the assessed tools were classified as having excellent methodological quality; their validation and reproducibility correlation coefficients were classified as moderate and high (r ≥ 0.40). CONCLUSIONS: Food frequency questionnaires developed for pregnant women appear to be reliable tools to assess food intake by this group. Overall, they had good methodological quality and adequate correlation coefficients compared with reference methods.

Prevalence of food addiction determined by the Yale Food Addiction Scale in Latin America: A systematic review with meta-analysis.

OBJECTIVE: Food addiction (FA) has been extensively investigated worldwide; however, the prevalence of FA in the Latin American population has yet to be established and past work has largely neglected the specificities of this region, that includes the most significant economic disparities in the world. Thus, the objective of this study was to assess the prevalence of FA measured by the Yale Food Addiction Scale in Latin America. METHOD: The search was performed on MEDLINE, ScienceDirect, LILACS, IBECS, SciELO, PsycArticles, CENTRAL, and the gray literature. FA prevalence data were collected, and random effects meta-analyses were performed to calculate the overall weighted prevalence, the prevalence by country, and by clinical and non-clinical samples. RESULTS: A total of 10,082 occurrences were identified through database searches, and 23 studies were included (Mexico = 9; Brazil = 7; Chile = 4; Argentina = 1; Peru = 1; Uruguay = 1). The prevalence of FA found in clinical samples was 38% (95% CI: 16%-63%; I2  = 98.67%; 8 studies), while in non-clinical samples, it was 15% (95% CI: 10%-21%; I2  = 98.51%; 15 studies). DISCUSSION: The average prevalence of FA in the Latin American countries included here was in accordance with that reported in other regions worldwide. It is noteworthy that the studies were conducted only in six countries, which are among those with the highest income in the region and do not represent the situation in native populations or those with lower purchasing power. This gap in the data also reflects the effects of economic disparities on the availability of empirical data in the region. PUBLIC SIGNIFICANCE: The prevalence of food addiction in Latin America was similar to that reported in other regions. It was higher among individuals with overweight, whether or not undergoing bariatric surgery, than in non-clinical samples. These findings contribute to aggregate information about this condition that has drawn the attention of clinicians and researchers.

OBJETIVO: La adicción a la comida (FA, por sus siglas en inglés) ha sido ampliamente investigada en todo el mundo; sin embargo, la prevalencia de la FA en la población latinoamericana aún no se ha establecido y el trabajo previo ha descuidado en gran medida las especificidades de esta región, que incluye las disparidades económicas más significativas del mundo. Por lo tanto, el objetivo de este estudio fue evaluar la prevalencia de FA medida por la Escala de Adicción a la Comida de Yale en América Latina. MÉTODO: La búsqueda se realizó en MEDLINE, ScienceDirect, LILACS, IBECS, SciELO, PsycArticles, CENTRAL y la literatura gris. Se recopilaron datos de prevalencia de FA y se realizaron metanálisis de efectos aleatorios para calcular la prevalencia ponderada general, la prevalencia por país y por muestras clínicas y no clínicas. RESULTADO: Se identificaron 10 082 casos mediante búsquedas en bases de datos y se incluyeron 23 estudios (México = 9; Brasil = 7; Chile = 4; Argentina = 1; Perú = 1; Uruguay = 1). La prevalencia de FA encontrada en muestras clínicas fue del 38% (IC95%:16%; 63%; I2 = 98,67%; 8 estudios), mientras que en muestras no clínicas, fue del 15% (IC del 95%: 10%; 21%; I2 = 98,51%; 15 estudios). DISCUSIÓN: La prevalencia promedio de FA en los países latinoamericanos incluidos aquí estuvo de acuerdo con la reportada en otras regiones del mundo. Cabe destacar que los estudios se realizaron solamente en seis países, que se encuentran entre los de mayores ingresos de la región y no representan la situación de las poblaciones nativas o de menor poder adquisitivo. Esta brecha en los datos también refleja los efectos de las disparidades económicas en la disponibilidad de datos empíricos en la región.
