RESUMO
Objective: To understand the association of food insecurity with sociodemographic factors in a sample population in Latin America during the COVID-19 pandemic. Methods: This was a multicenter cross-sectional study conducted in 10 countries in Latin America using an online survey through various digital platforms from October 14, 2020 to February 15, 2021. Statistical analysis of data was performed by applying descriptive statistics, chi-square test, and logistic regression analysis. Results: Of a total of 6 357 surveys, 58.2% of respondents experienced food security, 29.3% were slightly food insecure, 9.2% were moderately food insecure, and 3.3% were severely food insecure. Concerning the association food insecurity and sociodemographic variables, there is a significant association in the variables studied, including area of residence, education level, occupation, number of persons in the household, household with children younger than 10 years of age, and socioeconomic level. Conclusions: These findings indicate that sociodemographic factors associated with food insecurity during the COVID-19 pandemic in Latin America were rural residence; complete and incomplete basic and secondary schooling; occupation (homemaker, unemployed, and self-employed); low, medium-low, and medium socioeconomic level; household with more than four persons; and household with children younger than 10 years of age.
RESUMO
The intricate interplay between the gut microbiota and polyphenols has emerged as a captivating frontier in understanding and potentially harnessing the therapeutic potential of these bioactive compounds. Phenolic compounds, renowned for their antioxidant, anti-inflammatory, antidiabetic, and anticancer properties, are subject to intricate transformations within the gut milieu, where the diverse microbial ecosystem exerts profound effects on their metabolism and bioavailability. Conversely, polyphenols exhibit a remarkable capacity to modulate the composition and activity of the gut microbiota, fostering a bidirectional relationship that extends beyond mere nutrient processing. This symbiotic interaction holds significant implications for human health, particularly in cardiometabolic diseases such as diabetes mellitus, metabolic-dysfunction-associated steatotic liver disease, and cardiovascular disease. Through a comprehensive exploration of molecular interactions, this narrative review elucidates the reciprocal dynamics between the gut microbiota and polyphenols, unveiling novel avenues for therapeutic intervention in cardiometabolic disorders. By unravelling the intricate cross-talk between these two entities, this review underscores the multifaceted roles of polyphenols in overall health and the pivotal role of gut microbiota modulation as a promising therapeutic strategy in mitigating the burden of cardiometabolic diseases.

OBJECTIVE: We estimated the association between the consumption of select ultra-processed food (UPF), homemade fried food and overweight/obesity in Latin American university undergraduate students during the COVID-19 pandemic. METHODS: We conducted an analytical cross-sectional study. 4539 university students (73.6% female, mean age 22.5 ± 4.4) from 10 Latin American countries completed a self-administered online survey. UPF eating habits and homemade fried food were measured according to a validated survey. Height and body weight were self-reported. Body mass index (BMI) was calculated. A BMI ≥25 kg/m2 was categorized as overweight/obesity. Ordinal logistic regression models were applied. RESULTS: Snacks (36.2%) and homemade fried food (30.2%) had a higher prevalence of consumption than sugary drinks (22.5%) and fast food (7.2%). The greatest strength of association was found between fast food consumption [odds ratio (OR) = 2.16; 95% confidence interval (CI): 1.63-2.85], sugary drinks [OR = 2.05; CI: 1.63-2.59] and homemade fried food [OR = 1.46; CI: 1.16-1.85] with overweight/obesity. CONCLUSION: Latin American university undergraduates present risky eating behaviors associated with overweight and obesity. Effective policies to promote healthy eating should be incorporated and issued from universities to reduce the consumption of UPF and promote homemade, healthier and more natural food.

INTRODUCTION: high-calorie and sugar-sweetened food is considered more pleasant food. People with anhedonia symptoms have difficulties experiencing pleasure in daily activities. However, is still unclear if anhedonia symptomatology increases palatable food consumption in the Chilean Adults sample. OBJECTIVE: to explore food networks in the Chilean Adults sample and in people with anhedonia symptom. METHODS: the sample was recruited through digital platforms. Pregnant or lactating women and subjects under pharmacological treatment or psychotherapy were excluded. A total of 1242 subjects, 76.6% women, with a mean age of 30.7 (SD 9.3) and who were highly educated, participated in the study. Data were collected through an online survey. A questionnaire on food consumption based on daily and weekly frequency was used, as well as the Snaith-Hamilton Pleasure Scale to measure anhedonia symptoms. We employed the Gaussian graph model (GGM) to analyze food consumption as networks. We started with the total sample, and then we repeated the analysis on a subsample with anhedonia symptoms, and next on a subsample with exclusively food-related anhedonia. RESULTS: in the total sample, a positive and strong relationship was observed between fruits and vegetables, as well as a negative association with the triad of sugar-sweetened beverages, fast food, and fried food. The network in anhedonic subjects shows that "pasta, rice & potatoes" and "bread" have a stronger association and a more central place in the network compared those without anhedonia symptoms. CONCLUSIONS: Subjects with anhedonia symptoms have a more central consumption of foods with a high or medium glycemic index compared to subjects without anhedonia symptoms, which could trigger the development of chronic diet-related diseases.
RESUMO
Cancer is a process involving cell mutation, increased proliferation, invasion, and metastasis. Over the years, this condition has represented one of the most concerning health problems worldwide due to its significant morbidity and mortality. At present, the incidence of cancer continues to grow exponentially. Thus, it is imperative to open new avenues in cancer research to understand the molecular changes driving DNA transformation, cell-to-cell interaction derangements, and immune system surveillance decay. In this regard, evidence supports the relationship between chronic inflammation and cancer. In light of this, a group of bioactive lipids derived from polyunsaturated fatty acids (PUFAs) may have a position as novel anti-inflammatory molecules known as the specialized pro-resolving mediators (SPMs), a group of pro-resolutive inflammation agents that could improve the anti-tumor immunity. These molecules have the potential role of chemopreventive and therapeutic agents for various cancer types, and their effects have been documented in the scientific literature. Thus, this review objective centers around understanding the effect of SPMs on carcinogenesis and their potential therapeutic effect.

Cardiovascular disease (CVD) is a global public health issue due to its high morbidity, mortality, and economic impact. The implementation of innovative therapeutic alternatives for CVD is urgently required. Specialized proresolving lipid mediators (SPMs) are bioactive compounds derived from ω-3 and ω-6 fatty acids, integrated into four families: Lipoxins, Resolvins, Protectins, and Maresins. SPMs have generated interest in recent years due to their ability to promote the resolution of inflammation associated with the pathogeneses of numerous illnesses, particularly CVD. Several preclinical studies in animal models have evidenced their ability to decrease the progression of atherosclerosis, intimal hyperplasia, and reperfusion injury via diverse mechanisms. Large-scale clinical trials are required to determine the effects of SPMs in humans. This review integrates the currently available knowledge of the therapeutic impact of SPMs in CVD from preclinical and clinical studies, along with the implicated molecular pathways. In vitro results have been promising, and as such, SPMs could soon represent a new therapeutic alternative for CVD.

INTRODUCTION: This study aimed to determine the relationship between symptoms of anxiety and/or anhedonia (inability to feel pleasure) and diet quality during confinement due to COVID-19 in rural populations in Latin America. METHODS: This was a multicentric, cross-sectional study. An online survey was applied, which included the Beck Anxiety Inventory, Snaith-Hamilton Pleasure Scale for assessing the presence of anhedonia, the Food Intake Questionnaire and sociodemographic questions. RESULTS: The study included 10 552 people from 11 countries; 708 participants were living in rural areas. More than half of the participants were quarantined at the time of the survey. Diet quality was inversely associated with anhedonia (p<0.001) and anxiety (p=0.003). In addition, a healthier diet was associated with being female (p=0.030), having a higher level of education (p=0.008) and country of residence (p=0.001). CONCLUSION: Among the rural population during the COVID pandemic, this study found a worse diet quality was associated with symptoms of anhedonia and anxiety, as well as lower level of education and being male. Proposals to improve the quality of the diet could include interventions aimed at people's mental health.

Due to the inability to curb the excessive increase in the prevalence of obesity and overweight, it is necessary to comprehend in more detail the factors involved in the pathophysiology and to appreciate more clearly the biochemical and molecular mechanisms of obesity. Thus, understanding the biological regulation of adipose tissue is of fundamental relevance. Connexin, a protein that forms intercellular membrane channels of gap junctions and unopposed hemichannels, plays a key role in adipogenesis and in the maintenance of adipose tissue homeostasis. The expression and function of Connexin 43 (Cx43) during the different stages of the adipogenesis are differentially regulated. Moreover, it has been shown that cell-cell communication decreases dramatically upon differentiation into adipocytes. Furthermore, inhibition of Cx43 degradation or constitutive overexpression of Cx43 blocks adipocyte differentiation. In the first events of adipogenesis, the connexin is highly phosphorylated, which is likely associated with enhanced Gap Junction (GJ) communication. In an intermediate state of adipocyte differentiation, Cx43 phosphorylation decreases, as it is displaced from the membrane and degraded through the proteasome; thus, Cx43 total protein is reduced. Cx is involved in cardiac disease as well as in obesity-related cardiovascular diseases. Different studies suggest that obesity together with a high-fat diet are related to the production of remodeling factors associated with expression and distribution of Cx43 in the atrium.

BACKGROUND: Health-related quality of life (HRQoL) is an important predictor of health outcomes in chronic kidney disease (CKD) including those patients in renal replacement therapy. Its evaluation through validated questionnaires is essential for comprehensive care in people undergoing renal replacement therapy. AIM: To evaluate the quality of life in patients with CKD on peritoneal dialysis. MATERIAL AND METHODS: Descriptive cross-sectional study. The KDQOL-36 quality of life questionnaire was applied to 67 patients aged 55 ± 15 years, in peritoneal dialysis at a public hospital in Santiago. Scores range from 0 to 100, values greater than 50 represent a better HRQoL. RESULTS: The burden, symptoms, and effects of kidney disease component of the survey had scores over 50. Women, people without diabetes, those actively working and those with better incomes reported a better HRQoL. CONCLUSIONS: These patients on peritoneal dialysis report a good quality of life, especially in the specific components of kidney disease.

OBJECTIVE: To associate health anthropometric indexes with physical fitness of elderly women (EW) who participate in physical exercise workshops. MATERIALS AND METHODS: 272 Chilean women over 60 years took part in the study. The variables studied were BMI, waist circumference (WC), waist-height index (WHI) and physical fitness (PF). Correlations were made through the Pearson or Spearman coefficient, and bivariate associations using Pearson's Chi-square and the Fisher's exact test, considering p<0.05. RESULTS: 70.8% of the EW were overweight or obese; 68.8% and 96% were at cardiometabolic risk due to their WC and WHI, respectively. Their PF showed equal performance (53.5%) or higher (33.8%) according to their age and gender. Inverse correlations were found between nutritional status and cardiometabolic risk with PF tests (except for agility and dynamic balance [direct]), and direct association with back scratch test. CONCLUSIONS: Excess weight in physically active EW would not affect their physical-functional performance; however, cardiometabolic risk would be inversely associated with motor function.
OBJETIVO: Asociar los índices antropométricos de salud con la condición física de las mujeres mayores (MM) que participan en talleres de ejercicio físico. MATERIAL Y MÉTODOS: Participaron 272 mujeres chilenas mayores de 60 años. Las variables correspondieron al IMC, perímetro de cintura (PC), índice cintura estatura (ICE) y condición física (CF). Se realizaron correlaciones a través del coeficiente de Pearson o Spearman, y asociaciones bivariadas mediante ji cuadrada de Pearson y el test exacto de Fisher, considerando un p<0.05. RESULTADOS: De las MM, 70.8% alcanzó sobrepeso u obesidad; y 68.8% y 96% riesgo cardiometabólico de acuerdo con PC e ICE, respectivamente. Su CF presentó un rendimiento igual (53.5%) o superior (33.8%) según su edad y sexo. Se encontraron correlaciones inversas entre estado nutricional y riesgo cardiometabólico con las pruebas de CF (excepto la agilidad y equilibrio dinámico, en donde la relación fue directa), y asociación directa con juntar manos. CONCLUSIONES: El exceso de peso en MM físicamente activas no afecta su rendimiento físico-funcional; sin embargo, el riesgo cardiometabólico se asocia inversamente con la funcionalidad motriz.

OBJECTIVE: To determine the association between academic performance and eating behavior in university students in Chile. METHODS: A total of 680 college students, 409 (60%) women and 271 (40%) men, were randomly recruited and the mean age of the entire sample was 26. The Three-Factor Eating Questionnaire (TFEQ), which evaluates 3 dimensions of eating behavior-cognitive restriction (limiting own intake), uncontrolled eating (inclination to eat), and emotional eating (control of food intake in the context of negative emotions)-was used. Academic performance was measured by the grade point average (GPA) and was associated with eating behavior. RESULTS: Women had significantly higher scores in the "emotional eating" dimension than men (p = 0.002). The eating behavior analysis showed that female students with higher GPAs (above 5.5) had statistically significantly lower uncontrolled eating scores (p = 0.03) and higher cognitive restriction scores (p = 0.05) than women with lower academic performance (below 5.5). There were no significant associations between eating behavior and academic performance in men. CONCLUSIONS: A positive association between eating behavior and academic performance was observed in female university students in Chile. Further studies are needed to explore the causes of this association and determine how to improve the nutritional habits of this population.

BACKGROUND: The association between non-nutritive sweeteners and obesity is controversial. AIM: To determine whether the consumption of non-nutritive sweeteners is related to higher risk for overweight or obesity among university students in Chile, Panama, Guatemala and Peru. MATERIAL AND METHODS: A total of 1,224 (472 from Chile, 300 from Panama, 248 from Guatemala and 204 from Peru) male and female university students aged between 18 and 26 years participated in the study. Each student reported their food intake (frequency of weekly consumption) in a survey that contained photos of foods containing non-nutritive sweeteners adapted for each country. Anthropometry was also measured. RESULTS: More than 80% of students consumed at least one product containing non-nutritive sweeteners. Females who ate acesulfame potassium and sucralose had a lower risk of overweight or obesity with an odds ratio (OR) of 0.5 (confidence intervals (CI) = 0.3-0.9; p = 0.003) and OR = 0.4 (IC = 0.2-0.8; p = 0.01), respectively. CONCLUSIONS: In this sample of Latinamerican university students, consumption of non-nutritive sweeteners was associated with lower risk of overweight only in females.

OBJECTIVES: During the coronavirus 2019 pandemic, there had been more than 758 million COVID-19 cases as of February 13, 2023, and it is the main cause of death in many countries. Due to the variation in disease presentation, scientists determined that people living with type 2 diabetes mellitus were at higher risk of mortality. However, people living with type 1 diabetes have not been thoroughly studied, especially in extreme regions of developing countries. The objective of this study was to analyze the effects of SARS-CoV-2 pandemic restrictions on different variables in a cohort with type 1 diabetes. METHODS: This cohort-type study included pediatric and adult patients with type 1 diabetes at Regional Hospital Dr. Juan Noé Crevani in Arica, Chile. Biosocial and anthropometric factors, clinical history, self-care activities, and biochemical parameters were assessed and compared using analysis of variance and paired t tests between March 2020 and March 2021. RESULTS: A total of 150 patients were assessed during the SARS-CoV-2 pandemic in Arica, Chile. One year after the pandemic struck, the main causes for metabolic deterioration were a reduction of carbohydrate counting by an average of 8.67% (P = 0.000), a reduction of adherence to treatment by an average of 25% (P = 0.000), and a shift to telemedicine as a main health care service (P = 0.023); these factors raised hemoglobin A1c (HbA1c) levels by 1.81%, 1.78% and 0.075%, respectively. The participants' average body mass index (BMI) increased by 1.26 kg/m2 and HbA1c levels increased by 0.16% during the first year of the pandemic. Also, hospitalizations increased about 2% (P = 0.984), and there was a significant increase in carbohydrate and snack intake (P = 0.330 and P = 0.811, respectively). Children's linear growth decreased by a standard deviation of 0.035 (P = 0.648), and their physical activity decreased by 12.67% (P = 0.383). CONCLUSIONS: This study found that adherence to diabetes care was reduced during the pandemic owing to a variety of behavioral reasons and environmental changes (e.g., quarantines and food security). This affected this population's HbA1c levels, BMI, linear growth, and number of hospitalizations as main consequences. Telemedicine remains an important tool, but it must be reconsidered among all different age groups.

Although thermal treatments are beneficial for the preservation and safety of milk, they can also alter its immunogenic activity by affecting its protein components. To achieve precise results, it is essential to identify the specific proteins that cause food allergies. Therefore, investigating the possible alterations of cow's milk proteins (CMPs) resulting from thermal treatments is necessary. In this study, the Fourier transform infrared spectroscopy (FTIR) technique was used to analyze the effect of UHT thermal treatment on the secondary structures of milk casein. Using the second derivative, six characteristic peaks were identified in the Amide I region, ranging from 1700 to 1600 cm-1. It was found that thermal treatments produce shifts in absorption peaks, indicating changes in protein conformation and possibly in allergenic activity. These shifts were clearly identified in the first characteristic peak of samples M8 and M9, from 1621 to 1600 cm-1. The results suggest that thermal treatments may promote protein aggregation by increasing ß turns and reducing ß sheets and α helices, which could enhance the allergenic potential of the proteins and facilitate the formation of complexes between different milk proteins, such as ß-lactoglobulin and κ-casein. Further studies are needed to experimentally validate the allergenic activity of proteins modified by thermal treatments, as only an analytical method (FTIR) was used to evaluate the secondary structures of the proteins.
RESUMO
Positional cranial deformities are associated with prematurity evolving during the first 2 years of life due to the malleable characteristics of the skull, the first year being the main/primary therapeutic window for intervention. The objectives were (a) to describe health characteristics, peri- and postnatal pathologies, and positional cranial deformities in infants enrolled in an early intervention program and (b) to analyze the effects of a parent education-based intervention program on positional cranial deformity in premature infants. A quantitative, analytical, longitudinal study was conducted. It included 103 premature infants enrolled in an early intervention program (EIP) during the year 2017, all under 4 months of corrected age, to whom a parent education-based intervention program was applied. Cranial circumference, cranial width, diagonals, and anteroposterior diameter were measured, and the cranial asymmetry index (CAI) and cephalic index (CI) were calculated at baseline and during two subsequent evaluations separated by a 3-month period. The main results showed that 75.7% of the infants belonged to a very premature gestational age category, and 57.3% had an adequate weight for gestational age. The most frequent pathologies were premature jaundice, premature anemia, and hyaline membrane disease. The most frequent positional cranial deformity was plagiocephaly. The parent education-based intervention program resulted in (1) a significant decrease in the CAI and a significant increase in the IC, (2) plagiocephalies: an increase in the mild category and a decrease in the moderate + severe categories, (3) brachycephalies: a decrease in the absence category and an increase in the moderate + severe category, and (4) dolichocephalies: an increase in the absence category and a decrease in the mild category. In conclusion, the recommended first line of intervention was not enough for this population, and future studies should support the development of national clinical guidelines, where education is complemented with other therapeutic measures.
RESUMO
A Mediterranean diet (MedDiet) has emerged as a crucial dietary choice, not only in attenuating various adolescents' metabolic health issues but it has also been associated with improved cognitive and academic achievement. However, few studies have established patterns of food consumption linked to both cognitive and academic achievement in adolescents living in a developing country with non-Mediterranean-based food. Methods: This cross-sectional study included 1296 Chilean adolescents (50% girls) aged 10-14 years. The MedDiet Quality Index was used to assess adherence to the MedDiet in children and adolescents. Through cluster analysis, four distinct dietary patterns were identified: Western diet (WD = 4.3%); low fruit and vegetables, high-sugar diet (LFV-HSD = 28.2%); low fruit and vegetables, low-sugar diet (LFV-LSD = 42.2%); and the MedDiet (25.3%). A mixed-model analysis was conducted to compare these clusters and their relationships with cognitive and academic achievements. Principal component analysis was performed to identify four primary cognitive domains: working memory, cognitive flexibility, inhibitory control, and fluid reasoning. Academic achievement was determined with five school subjects (Language, English, Mathematics, Science, and History) and included the Academic-PISA score derived from the mean scores in Language, Mathematics, and Science. Results: A marked difference was observed between the four clusters, which was mainly related to the consumption of sugar, ultra-processed foods, fruits, and vegetables. According to cognitive performance, the MedDiet group showed higher performance across all domains than the LFV-HSD, LFV-LSD, and WD groups. Regarding academic achievement, the WD underperformed in all analyses compared to the other groups, while the MedDiet was the unique profile that achieved a positive difference in all academic subjects compared to the WD and LFV-HSD groups (p < 0.05). Conclusions: These findings suggest that higher adherence to Mediterranean-style-based patterns and better food quality choices are associated with improved cognitive and academic achievements.

BACKGROUND: The pandemic of coronavirus disease 2019 (COVID-19) pandemic confinement has an impact on stress levels, which causes changes in food purchase and consumption behaviors. The objective of this study is to associate food purchase prioritization with stress level during the COVID-19 pandemic confinement. METHODS: Multicenter, observational and cross-sectional study, an online questionnaire that included data on sociodemographic variables, stress factors and food purchase prioritization was disseminated through digital platforms and social networks. RESULTS: A number of 6357 participants were included, of whom 83.6% were female, 56.3% were from the middle socioeconomic level, 71.2% had completed higher education and 78.3% had a job. At greater stress levels it was observed a higher prioritization of canned foods (Odds ratio (OR): 1.91, 95% CI: 1.56; 2.34), sweets (OR: 1.58, 95% CI: 1.06; 2.34) and flours (OR: 1.45, 95% CI: 1.25; 1.68). While lower stress levels are associated with nuts (OR: 0.75, 95% CI: 0.66; 0.85), vegetables (OR: 0.82, 95% CI: 0.72; 0.94), and fruits (OR: 0.90, 95% CI: 0.80; 1.01), after adjusting for confounders. CONCLUSIONS: There is an association between food purchase prioritization and stress level during the COVID-19 confinement. At greater stress levels, individuals purchase more food, both healthy and unhealthy. The later may have a negative impact on people's health, leading to or further aggravating malnutrition by excess and nutrition-related noncommunicable diseases.

OBJECTIVE: To associate breakfast consumption frequency with self-reported nutritional status and dietary patterns of Latin American university students by human development. MATERIAL AND METHODS: This was a cross-sectional, multicenter observational study. University students from 11 Latin American countries (Argentina, Chile, Colombia, Costa Rica, Ecuador, Guatemala, Mexico, Peru, Paraguay, Panama and Uruguay) were invited to participate by answering an online self-administered questionnaire on food consumption and sociodemographic indicators, associations were investigated using logistic regression. RESULTS: The logistic regression analysis showed significant associations between breakfast consumption and the crude model, models 2 and 3 in countries with very high and upper-middle/high human development. However, after adjustment in the most comprehensive model, the association is no longer statistically significant. In the fully adjusted model of the variables, a significant relationship was observed between breakfast consumption and both healthy and unhealthy dietary patterns. Specifically, students who typically consume breakfast exhibit greater consumption of oatmeal and fruits, as well as healthier dinner choices. Conversely, they exhibit lower consumption of fast food, sugary drinks, and juices. In particular, in highly developed countries, along with the mentioned foods, consumption of dairy was linked to breakfast consumption in a positive way, while alcohol consumption was negatively associated. CONCLUSION: University students who eat breakfast on a regular basis maintain a healthier diet in comparison to those who do not, irrespective of their country's level of human development.

BACKGROUND: At hospital level, clinical nutritionists play a fundamental role in health recovery, contributing to shorter hospital stays and addressing hospital malnutrition. However, in Latin America no studies have been conducted on the activities of the nutritionist and the factors influencing their performance. AIMS: to describe the activities of the clinical nutritionist in public and private hospital settings in Latin America and to determine the factors associated with disciplinary practice. METHODS: A cross-sectional analytical, quantitative study was conducted. Participants consisted of hospital nutritionists from 13 Latin American countries who had participated in a previously validated online survey on the activities performed during their daily work, obtaining a Professional Activities Score (PAS). RESULTS: 1222 nutritionists participated. Of the activities associated with the professional role, the only ones who reached over 75 % of execution were: performing nutritional intervention; performing nutritional assessment and diagnosis; providing counseling and dietary prescription; developing nutritional care plans for patients with nutritional problems; and performing the monitoring and evaluation of results of priority patients. The least frequent activities were: university teaching and collaborating in research. Regarding the reasons for not performing activities: 34.0 % reported not being included in the activities, 24.5 % mentioned lack of time, and 13.6 % indicated that the activities were conducted by another professional. Variables positively associated with an increase in the PAS were: having spent more years exercising the profession (Beta: 0.028, 95 % CI: 0.004; 0.051), and having a greater number of specialties (4 or more, Beta: 2.294, 95 % CI: 1.031; 3.557). Working in lower-complexity facilities (Low: Beta: -1.037, 95 % CI: -1.443; -0.630), and having more reasons for not performing the activities (3 or more: Beta: -3.105, 95 % CI: -4.111; -2.099) were inversely associated. From the sample, 1.8 % held a doctorate in clinical nutrition, 43.9 % had a specialty, and 64.4 % had a diploma or postgraduate degree in clinical nutrition. CONCLUSION: None of the activities related to the nutritionist work was performed on a 100 % basis. In Latin America, Ministries of Health should standardize and regulate the functions of the clinical nutritionist, as well as quantifying understaffing and proposing solutions to alleviate the shortage of these professionals, acknowledging the positive impact that they have on the recovery of hospital patients.
