Psychological factors of diet quality among rural populations of Latin America during the COVID-19 pandemic: a cross-sectional study.

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.

Educational attainment and mental health conditions: a within-sibship Mendelian randomization study.

Importance: Observational studies have demonstrated consistent protective effects of higher educational attainment (EA) on the risk of suffering mental health conditions (MHC). Determining whether these beneficial effects are causal is challenging given the potential role of dynastic effects and demographic factors (assortative mating and population structure) in this association. Objective: To evaluate to what extent the relationship between EA and various MHC is independent from dynastic effects and demographic factors. Design: Within-sibship Mendelian randomization (MR) study. Setting: One-sample MR analyses included participants' data from the Trøndelag Health Study (HUNT, Norway) and UK Biobank (United Kingdom). For two-sample MR analyses we used summary statistics from publicly available genome-wide-association-studies. Participants: 61 880 siblings (27 507 sibships). Exposure: Years of education. Main outcomes: Scores for symptoms of anxiety, depression and neuroticism using the Hospital Anxiety Depression Scale (HADS), the 7-item Generalized Anxiety Disorder Scale (GAD-7), the 9-item Patient Health Questionnaire (PHQ-9), and the Eysenck Personality Questionnaire, as well as self-reported consumption of psychotropic medication. Results: One standard deviation (SD) unit increase in years of education was associated with a lower symptom score of anxiety (-0.20 SD [95%CI: -0.26, -0.14]), depression (-0.11 SD [-0.43, 0.22]), neuroticism (-0.30 SD [-0.53, -0.06]), and lower odds of psychotropic medication consumption (OR: 0.60 [0.52, 0.69]). Estimates from the within-sibship MR analyses showed some attenuation, which however were suggestive of a causal association (anxiety: -0.17 SD [-0.33, -0.00]; depression: -0.18 SD [-1.26, 0.89]; neuroticism: -0.29 SD [-0.43, -0.15]); psychotropic medication consumption: OR, 0.52 [0.34, 0.82]). Conclusions and Relevance: Associations between EA and MHC in adulthood, although to some extend explained by dynastic effects and demographic factors, overall remain robust, indicative of a causal effect. However, larger studies are warranted to improve statistical power and further validate our conclusions.

The double burden of malnutrition and gross motor development in infants: A cross-sectional study.

OBJECTIVE: The objective of the present work was to study the relationship between the double burden of malnutrition and gross motor development in infants. METHOD: ology: Sample included 5900 infants under 24 months of age, participants of the ENSANUT-ECU study. To evaluate nutritional status, we calculated z-scores for body mass index/age (BAZ) and height/age (HAZ). Six gross motor milestones were considered: sitting without-support, crawling, standing and walking with-support, standing and walking without-support. Data was analysed using logistic regression models in R. RESULTS: Independently form age, sex and other socio-economic factors, the probability of achieving three gross motor milestones was significantly lower among chronically undernourished infants compared to their peers: sitting without-support, crawling, and walking without-support. Compared to no malnourished infants the probability of sitting without-support at six months was 10% lower for chronically undernourished infants (0.70, 95%CI [0.64-0.75]; 0.60, 95%CI [0.52-0.67]; respectively). The probability of crawling at eight months and walking without-support at 12 months were also significantly lower among chronically undernourished infants (0.62, 95%CI [0.58-0.67]); 0.25, 95%CI [0.20-0.30]; respectively) in comparison to no malnourished infants (0.67, 95%CI [0.63-0.72]); 0.29, 95%CI [0.25-0.34]; respectively). Obesity/overweight was not associated with the achievement of gross motor milestones, except for sitting without-support. Chronically undernourished infants with low or high BMI/age were generally delayed in the achievement of gross motor milestones than their peers. CONCLUSIONS: Chronic undernutrition is related to delayed gross motor development. Public health measures are needed to be implemented to prevent the double burden of malnutrition and its detrimental effects on infant development.

An exploratory assessment of human and animal health concerns of smallholder farmers in rural communities of Chimborazo, Ecuador.

BACKGROUND: Livestock play important economic and cultural roles in smallholder communities of Ecuador, yet they also serve as potential sources of zoonotic infections. Understanding the animal and human health concerns of smallholder farmers is important in guiding strategies for improvement of the health and livelihoods of these resource-poor farmers. Therefore, the objectives of this study were to: (a) assess the health concerns of smallholder farmers; (b) explore animal and waste management practices; and (c) identify predictors of pediatric and livestock diarrhea on smallholder farms in Ecuador. METHODS: This is a cross-sectional survey of 58 smallholder farmers in three communities of Chimborazo province, Ecuador. Data were collected on household demographics, smallholding characteristics, type of animals owned, human-animal interactions, health concerns, and 30-day occurrence of human as well as animal diarrhea. Summary statistics were computed and logistic models used to investigate predictors of pediatric and animal diarrhea. RESULTS: All respondents reported keeping animals. Animals kept included cattle, pigs, poultry, dogs, guinea pigs, cats, sheep, horses, rabbits, donkeys, or other livestock. More than half of the respondents named diseases as their greatest personal (55.2%) or family (58.6%) health concern, while an even greater percentage (60.3%) reported physiological stress as the primary health concern for their animals. Occurrence of diarrhea in the 30 days prior to the study was reported by 12.1% of the respondents. Additionally, 15.2% and 55.2% of the households reported diarrhea among children and animals, respectively. The majority (65.5%) of the households had toilets, while the remainder had either latrines (27.6%) or no sanitation facilities (6.9%). However, only 9.1% of the smallholdings had either a toilet (3.6%) or a latrine (5.5%) onsite and yet the farmers tended to spend most of the day at the smallholdings. Potential exposures to gastrointestinal pathogens included food- or water-borne sources (93.5% of children; 91.4% of adults) and blood-borne or fecal sources (80.4% of children; 100% of adults). Although 98.3% of the respondents kept cattle, only 27.6% had animal enclosures and even fewer (15.5%) had animal waste management plans. The odds of animal diarrhea were significantly higher (Odds Ratio [OR] = 8.7; 95% Confidence Interval [1.0-75.0]; p = .049) among households that had animal waste management plans compared to those that did not. None of the variables investigated were significant predictors of pediatric diarrhea. CONCLUSIONS: Ongoing surveillance is needed to develop estimates of diarrhea incidence among smallholder families and their livestock. The impact of different animal management strategies on the potential pathogen exposure of smallholders warrants further investigations. Improving sanitation infrastructure and animal waste management strategies is recommended.

Stress and Diet Quality Among Ecuadorian Adults During the COVID-19 Pandemic. A Cross-Sectional Study.

Background: Stress has been associated with food habits. Stress changes eating patterns and the salience and consumption of hyperpalatable foods. During the lock-down due to the COVID-19 pandemic, stress was very common. Objective: We investigated the association between stress and diet quality in Ecuadorian adults during the COVID-19 pandemic. Design: A cross-sectional study. Setting: Data was collected using a self-administered online survey. Stress was measured using the Perceived Stress Scale (PSS-14), and diet quality was evaluated using the Global Diet Index (GDI). A linear regression model with restrictive cubic splines was used to investigate the association between stress and diet quality. Participants: Participants were recruited by convenience sampling, including a total of 2602 individuals. Most participants were female (68.57%) and had university education (78.52%), with a median age of 25 (IQR: 25, 37). Results: Stress was reported by 26.06% of participants. The majority of individuals (75.79%) reported having a diet that needed changes or an unhealthy diet. Independently from biological sex, age, level of education, people/room ratio, economic allowance, and expenses for food, stress was statistically significantly associated with diet quality (p = 0.035). The association between stress and diet quality was inverse and non-linear; higher stress levels were associated with poorer diet quality. The consumption of palatable foods was not statistically significant associated with stress. Conclusions: Stress is associated with poorer diet quality. Public health measures to improve the mental health and lifestyle of the population are needed during the lock-down of the pandemic.

Cognitive function and vitamin B12 and D among community-dwelling elders: A cross-sectional study.

BACKGROUND & AIMS: Little is know on the association between mild or sub-clinical vitamin B12 or D deficiencies and cognitive decline. The objective of the present work was to evaluate the association between vitamin B12 and D levels, and cognitive function in community-dwelling elders. METHODS: Cross-sectional study that included data from elders who participated in the SABE study, a population-based study that was carried out in Ecuador. Participants of SABE were selected by probabilistic sampling from the whole country. Vitamin B12 and D were measured in blood and cognitive status was assessed using an abbreviated version of the minimental state examination (MMSE). RESULTS: The sample included 1733 elders from whom 936 (54.01%) were female. Independently from sex, age, years of education, ethnicity, socioeconomic status and geographical zone of residence, we found that vitamin B12 levels were associated to MMSE scores and that this relationship changed depending on age. In this way, we observed that from 75 years of age, drop of cognitive function was particularly steep in individuals with low levels of vitamin B12. We did not find evidence to support an association between vitamin D levels and cognitive function. CONCLUSIONS: Low levels of vitamin B12 but not of vitamin D are associated with low cognitive functioning in a sample of community-dwelling elders.

Mobility restrictions and mental health among young adults during the COVID-19 pandemic in Ecuador.

OBJECTIVE: To study the association between mobility restriction and mental health outcomes among Ecuadorian young adults. METHOD: The present is a cross-sectional study that included a non-probabilistic sample of mostly highly educated young adults. Socio-demographic and mental health data were collected through an online survey, between May and June 2020, when confinement was mandatory in Ecuador. Data on mobility was extracted from Google Community Mobility Reports. Four aspects of the participants' mental health were evaluated: eating behavior (emotional eating), depression, sleep quality and sense of coherence as a proxy of resilience, using previously validated instruments. Data were analyzed using multiple linear regression models in R. RESULTS: Sample included 8426 young adults, with a mean age of 22.85 (standard deviation: 4.43), most of whom were women (n=5943, 70.53%). During mandatory confinement, in Ecuador mobility in general was reduced by nearly 50% in comparison to January/February, 2020. Less healthy eating behavior, depression, worse sleep quality and lower sense of coherence were associated with higher mobility restriction to workplaces and groceries/pharmacies. Women and youngsters more often showed depression, less healthy eating behavior, worse quality of sleep and lower sense of coherence in comparison with men and older respondents. CONCLUSIONS: Mobility restrictions during COVID-19 pandemic were associated with worse self-reported mental health in a sample of young highly-educated Ecuadorian adults. Women and youngsters were the most affected. Our findings highlight the need of implementing health promotion measures directed to ameliorate the effects of confinement on mental health, focusing on women and youngsters.

Relationship between perceived stress and emotional eating. A cross sectional study.

BACKGROUND AND AIMS: Stress-related to self-isolation during the COVID-19 pandemic has shown a strong correlation with issues in the diet and health of the population. In this study, we aimed to relate the perceived stress of a group of Ecuadorian adults with emotional eating. METHODS: Cross-sectional design study. We applied validated questionnaires of perceived stress and emotional eating to adults of both sexes who virtually completed a form between the months of January and March 2021. The analyzes were carried out using Chi2 statistical tests, Student's t-tests and a multiple linear regression model., the analyzes were performed using the statistical software R. RESULTS: The sample was composed of 2333 participants, the median age was 25 years (interquartile range 21-37 years). Females reported more perceived stress than males (77.91% vs. 22.09%). Nearly 64% of participants who displayed perceived stress were emotional eaters. A statistically significant association was found between the emotional eating score and perceived stress (p < 0.001), the effect was an elevation of 0.44 points in the emotional eating score for each stress point perceived. For each unit increase in BMI the emotional eating score increased 0.26 units (p < 0.001) and for each unit increase in age the emotional eating score decreased by 0.27 units (p = 0.03). CONCLUSIONS: It is concluded that stress is associated to emotional eating. Dietary intake that responds to emotions and not to physiological hunger may have long-term problems related to unhealthy diet. It is recommended to consider stress and emotional eating in the nutritional care process of people.

Bodyweight change and its association with food and beverage consumption at the beginning COVID-19 confinement.

OBJECTIVES: SARS-CoV-2, a newly identified coronavirus responsible for the COVID-19 pandemic, has challenged health services and profoundly impacted people's lifestyles. The objective of the present study was to evaluate the effect of confinement during the COVID-19 pandemic on food consumption patterns and body weight in adults from 12 Ibero-American countries. METHODS: Multicentric, cross-sectional study. Data was collected using an online survey disseminated by social networks. The sample included 10 552 people from Spain and 11 Latin American countries who were selected by snowball sampling. RESULTS: While 38.50% of the sample reported weight gain, 16.90% reported weight lost. Weight change was associated with sex, age, country of residence, and education level. People who were not confined more often reported having maintained their weight in comparison to people who were confined. All Latin American countries showed an increased consumption of sweetened drinks, pastry products, fried foods, and alcoholic beverages during confinement. Consumption of eggs and dairy products was independent from body weight change. People who consumed more fruits and vegetables during confinement more often reported having lost weight. In contrast, body weight gain during confinement was associated with increased intake of sugary drinks, baked goods and pastries, pizza, fried foods, and alcoholic beverages. CONCLUSION: During COVID-19 confinement, the Latin American countries included in this study showed a change in their consumption patterns toward less healthy diets, which in turn was associated with an increase in the body weight of their population.

Quality of the diet during the COVID-19 pandemic in 11 Latin-American countries.

BACKGROUND AND OBJECTIVES: The confinement by COVID-19 has affected the food chain and environments, which added to factors such as anxiety, frustration, fear and stress have modified the quality of the diet in the population around the world. The purpose of this study was to explore diet quality during the COVID-19 pandemic in 11 Latin American countries. METHODOLOGY: Multicentric, cross-sectional study. An online survey was applied to residents of 11 Latin-American countries, during April and May 2020, when confinement was mandatory. Diet quality was evaluated using a validated questionnaire. RESULT: 10,573 people participated in the study. The quality of the food by country shows that Colombia presented the best quality, while Chile and Paraguay presented the lowest. When comparing the overall results of diet quality by gender, schooling and age, women, people with more schooling and people under 30 years of age, presented better diet quality. The regression model showed that the variables associated with diet quality were: age (df = 3, F = 4. 57, p < 0.001), sex (df = 1, F = 131.01, p < 0.001), level of education (df = 1, F = 38.29, p < 0.001), perception of weight change (df = 2, F = 135.31, p < 0.001), basis services (df = 1, F = 8.63, p = 0.003), and quarantine (df = 1, F = 12.14, p = 0.001). CONCLUSION: It is necessary for governments to intervene to reverse these indicators, considering that inadequate feeding favors the appearance of no communicable diseases, which favor a higher risk of infection and worse prognosis with COVID-19.

[Socio-demographic determinants of violence in older people in Ecuador]. / Determinantes sociodemográficos de violencia en adultos mayores ecuatorianos.

BACKGROUND AND OBJECTIVE: Older adults are at increased risk of violence. In order to prevent this, it is necessary to identify associated risk factors. The objective of the present study was to determine the association between violence and various socio-demographic factors (age, gender, ethnic group, level of education, and place of residence) in older adults. MATERIAL AND METHODS: Cross-sectional study that included participants from the SABE-Ecuador study, who were selected through probabilistic sampling and came from all over the national territory. Data were analysed with R using ordinal logistic regression models. RESULTS: Sample included 4321 older adults, women (52%) and men (48%), with a mean age of 72 years (SD 8). Having suffered violence was reported in 21.3% (n = 922) of older adults. It was observed that the odds of suffering violence was lower in men than in women (OR = 0.753, p< .001), decreased as age increased (OR = 0.989, p = .012) and decreased as level of education increased (primary vs. no education OR = 0.866, p = .001; secondary vs. no education OR = 0.622, p = .003; higher vs. no education OR = 0.323, p< .001). CONCLUSIONS: Being a woman and having a low level of education is associated with an increased risk of violence in older adults. Reducing gender gap and improving access to education for older adults could reduce their risk of violence.

Sleep quality does not mediate the negative effects of chronodisruption on body composition and metabolic syndrome in healthcare workers in Ecuador.

BACKGROUND AND AIMS: The objective of the present work was to determine to what extent sleep quality may mediate the association between chronodisruption (CD) and metabolic syndrome (MS), and between CD and body composition (BC). METHODOLOGY: Cross-sectional study which included 300 adult health workers, 150 of whom were night shift workers and thereby exposed to CD. Diagnosis of MS was made based on Adult Treatment Panel III criteria. Sleep quality was measured using the Pittsburgh Sleep Quality Index. Body mass index (BMI), fat mass percentage, and visceral fat percentage were measured as indicators of body composition (BC). Data were analyzed using logistic, linear regression and structural equation models. RESULTS: The odds of health workers exposed to CD to suffer MS was 22.13 (IC95 8.68-66.07) when the model was adjusted for age, gender, physical activity and energy consumption. CD was also significantly associated with an increase in fat mass and visceral fat percentages, but not to BMI. Surprisingly, there was not enough evidence supporting the hypothesis that sleep quality contributes to the association between CD and MS or between CD and BC. CONCLUSIONS: Sleep quality does not mediate the negative effects of CD on MS nor on BC.

[Estimation of weight based on age in Ecuadorian boys and girls: a validation of the APLS formula]. / Estimación del peso conforme a la edad en niños y niñas ecuatorianos: validación de la ecuación APLS.

INTRODUCTION: Introduction: in children the use of therapeutic interventions, which includes the administration of medications, is based on body weight. Objective: to validate the equations proposed by "Advanced Pediatric Life Support - APLS" in 2011 (APLS 1) and 2001 (APLS 2) to estimate weight in Ecuadorian girls and boys, considering their ethnic diversity and age groups. Methods: a cross-sectional study which included 21,735 girls and boys belonging to three ethnic groups: mestizo, indigenous, and other (white, black, and mulatto), with ages between 0 and 12 years, who participated in the ENSANUT-ECU study. Differences, Spearman's correlation, Bland-Altman graphs, and percentage error (PE) were calculated. Data were processed and analyzed using R. Results: APLS 1 tends to overestimate weight whereas APLS 2 underestimates it. The estimated weight bias was greater for the classical equation. The indigenous and "other" ethnic groups presented the highest differences with respect to measured weight. The differences between estimated weight and measured weight increased progressively with age. With APLS 1, the percentage of individuals with a PE > 10 % was greater than with APLS 2. Conclusions: APLS does not accurately estimate weight in the Ecuadorian pediatric population. The difference between estimated weight and measured weight is sensitive to ethnic and age differences.

Objetivo: validar las ecuaciones propuestas por "Advanced Pediatric Life Support ­ APLS" en 2011 (APLS 1) y 2001 (APLS 2) para estimar el peso de las niñas y niños ecuatorianos, considerando la diversidad étnica y los grupos de edad. Métodos: estudio transversal que incluyó 21.735 niñas y niños pertenecientes a tres grupos étnicos ­mestizo, indígena y otro (blancos, negros y mulatos)­ con edades comprendidas entre 0 y 12 años y que habían participado en el estudio ENSANUT-ECU. Se calcularon las diferencias, la correlación de Spearman, los gráficos de Bland-Altman y el porcentaje error (PE). Los datos se procesaron y analizaron usando R. Resultados: la APLS 1 tiende a sobrestimar el peso mientras que la APLS 2 lo subestima. El sesgo del peso estimado fue mayor para la ecuación clásica. Los grupos étnicos indígena y otro presentaron las diferencias más altas con respecto al peso medido. Las diferencias de peso estimado con respecto al medido aumentaron progresivamente con la edad. Con la APLS 1, el porcentaje de individuos con un PE > 10 % fue mayor que con la APLS 2. Conclusiones: la APLS no estima con exactitud el peso en la población pediátrica ecuatoriana. La diferencia entre el peso estimado y el peso medido es sensible a las diferencias étnicas y de edad.

Blood Pressure in Andean Adults Living Permanently at Different Altitudes.

Vinueza Veloz, Andrés Fernando, Aymaru Kailli Yaulema Riss, Chris I. De Zeeuw, Tannia Valeria Carpio Arias, and María Fernanda Vinueza Veloz. Blood pressure in Andean adults living permanently at different altitudes. High Alt Med Biol. 21:360-369, 2020. Aims: To estimate the association between blood pressure (BP) and chronic exposure to altitude in nonhypertensive Andean adults, while taking ethnicity into consideration. Materials and Methods: Sample included 10,041 nonhypertensive adults with indigenous or mixed ethnic background (the latter also referred to as mestizos), who permanently lived at different altitudes. BP was measured following international recommendations. Altitude was measured in meters above the sea level (masl) using a global positioning system. Data were analyzed through linear regression models with restricted cubic splines. Results: A significant nonlinear relation between altitude and systolic blood pressure (SBP) as well as diastolic blood pressure (DBP) was found (both p < 0.001). BP described a j-shaped curve, where the minimum was observed between 750 and 1250 masl, from where both SBP and DBP rose as altitude increased. These associations were independent from sex, age, index of economic wellbeing, body mass index, and years of education. Interestingly, at all altitudes indigenous people had lower SBP and DBP in comparison to mestizos (both p < 0.001). Conclusions: Living permanently at altitudes ≥750 masl is associated with higher SBP and DBP in Andean dwellers and this association is modulated by their ethnic background.

Genetic risk for Alzheimer disease in children: Evidence from early-life IQ and brain white-matter microstructure.

It remains unclear whether the genetic risk for late-onset Alzheimer disease (AD) is linked to premorbid individual differences in general cognitive ability and brain structure. The objective of the present study was to determine whether the genetic risk of late-onset AD is related to premorbid individual differences in intelligence quotient (IQ) and characteristics of the cerebral white-matter in children. The study sample included children of the Generation R Study from Rotterdam, The Netherlands. IQ was measured using a well-validated Dutch nonverbal IQ test (n = 1908) at ages 5 to 9 years. White-matter microstructure was assessed by measuring fractional anisotropy (FA) of white-matter tracts using diffusion tensor imaging (DTI) (n = 919) at ages 9 to 12 years. Genetic risk was quantified using three biologically defined genetic risk scores (GRSs) hypothesized to be related to the pathophysiology of late-onset AD: immune response, cholesterol/lipid metabolism and endocytosis. Higher genetic risk for late-onset AD that included genes associated with immune responsivity had a negative influence on cognition and cerebral white-matter microstructure. For each unit increase in the immune response GRS, IQ decreased by 0.259 SD (95% CI [-0.500, -0.017]). For each unit increase in the immune response GRS, global FA decreased by 0.373 SD (95% CI [-0.721, -0.026]). Neither cholesterol/lipid metabolism nor endocytosis GRSs were associated with IQ or cerebral white-matter microstructure. Our findings suggest that elevated genetic risk for late-onset AD may in part be manifest during childhood neurodevelopment through alterations in immune responsivity.

Objetivo: Estudiar la asociación entre la restricción de movilidad y la salud mental en personas adultas jóvenes de Ecuador. Método: Estudio transversal que incluyó una muestra no probabilística de personas adultas jóvenes con alto nivel de educación. Los datos sociodemográficos y de salud mental se recolectaron entre mayo y junio de 2020, cuando el confinamiento fue obligatorio, usando una encuesta en línea. Los datos sobre movilidad se extrajeron de Google Community Mobility Reports. Se evaluaron cuatro aspectos de la salud mental: alimentación emocional, depresión, calidad de sueño y sentido de coherencia como proxy de resiliencia, usando instrumentos previamente validados. Los datos se analizaron con modelos de regresión lineal múltiple usando R. Resultados: La muestra incluyó 8426 jóvenes, con una edad media de 22,85 años (desviación estándar: 4.43), mujeres en su mayoría (n = 5943, 70.53%). Durante el confinamiento obligatorio, la movilidad se redujo aproximadamente un 50%. Comportamientos alimentarios menos saludables, depresión, peor calidad del sueño y menor sentido de coherencia se asociaron con mayor restricción de movilidad a lugares de trabajo y pequeños comercios o farmacias. Mujeres y jóvenes mostraron con mayor frecuencia depresión, conductas alimentarias menos saludables, peor calidad del sueño y menor sentido de coherencia. Conclusiones: Las restricciones de movilidad durante la pandemia de COVID-19 se asociaron con una peor salud mental en personas adultas jóvenes con alto nivel de educación. Mujeres y jóvenes fueron los más afectados. Es necesario implementar medidas de promoción de la salud dirigidas a paliar los efectos del confinamiento en la salud mental, especialmente en mujeres y jóvenes. (AU)

SLC26A11 (KBAT) in Purkinje Cells Is Critical for Inhibitory Transmission and Contributes to Locomotor Coordination.

Chloride homeostasis determines the impact of inhibitory synaptic transmission and thereby mediates the excitability of neurons. Even though cerebellar Purkinje cells (PCs) receive a pronounced inhibitory GABAergic input from stellate and basket cells, the role of chloride homeostasis in these neurons is largely unknown. Here we studied at both the cellular and systems physiological level the function of a recently discovered chloride channel, SLC26A11 or kidney brain anion transporter (KBAT), which is prominently expressed in PCs. Using perforated patch clamp recordings of PCs, we found that a lack of KBAT channel in PC-specific KBAT KO mice (L7-KBAT KOs) induces a negative shift in the reversal potential of chloride as reflected in the GABAA-receptor-evoked currents, indicating a decrease in intracellular chloride concentration. Surprisingly, both in vitro and in vivo PCs in L7-KBAT KOs showed a significantly increased action potential firing frequency of simple spikes, which correlated with impaired motor performance on the Erasmus Ladder. Our findings support an important role for SLC26A11 in moderating chloride homeostasis and neuronal activity in the cerebellum.

METHODS: a cross-sectional study which included 21,735 girls and boys belonging to three ethnic groups: mestizo, indigenous, and other (white, black, and mulatto), with ages between 0 and 12 years, who participated in the ENSANUT-ECU study. Differences, Spearman's correlation, Bland-Altman graphs, and percentage error (PE) were calculated. Data were processed and analyzed using R. RESULTS: APLS 1 tends to overestimate weight whereas APLS 2 underestimates it. The estimated weight bias was greater for the classical equation. The indigenous and "other" ethnic groups presented the highest differences with respect to measured weight. The differences between estimated weight and measured weight increased progressively with age. With APLS 1, the percentage of individuals with a PE > 10 % was greater than with APLS 2. CONCLUSIONS: APLS does not accurately estimate weight in the Ecuadorian pediatric population. The difference between estimated weight and measured weight is sensitive to ethnic and age differences

Anthropometry, dietetic habits and sleepiness in Ecuadorian adults

The reduction of hours of sleep affects the physical and mental health of people. Having unhealthy sleep habits are associated with a greater occurrence of daytime sleepiness, which in turn has been related to poorer nutritional status. The objective of this study was to relate food intake, anthropometric measurements, and daytime sleepiness in Ecuadorian adults. Non-experimental, cross-sectional study, the sample included 400 men and women between 18 and 65 years of age, who attended an outpatient consultation of general medicine, family medicine, and traumatology services of a public hospital in Quito-Ecuador. Anthropometric and body composition measurements were measured using tetrapolar bio-impedance, following the recommendations of the International Society for the Advancement of Anthropometry (ISAK). Caloric intake was measured using a 24-hour recall and for daytime sleepiness (DS) the Epworth questionnaire was used. Statistical analyzes were performed using R. From the sample 56.5% presented DS, which affected women more frequently compared to men (p < 0.05). Differences were found between body measurements and dietary intake between groups of people with and without DS. Caloric intake, waist circumference, percentage of fat mass were higher in people with DS (p < 0.05), while muscle mass was higher in subjects without DS (p <0.05). No differences were found concerning visceral fat. We conclude that SD is related to less healthy values in terms of dietary intake and anthropometric measures(AU)

La reducción de las horas de sueño afecta la salud física y mental de las personas. Tener hábitos de sueño poco saludables se asocia a una mayor ocurrencia de somnolencia diurna, lo que a su vez se ha relacionado con un peor Estado Nutricional. El objetivo de este estudio fue relacionar la ingesta de alimentos, las medidas antropométricas y la somnolencia diurna en adultos ecuatorianos. Estudio no experimental, transversal n=400 hombres y mujeres entre 18 y 65 años, que acudieron a consulta externa de los servicios de medicina general, medicina familiar y traumatología de un hospital público de Quito, Ecuador tomado como referencia. Se tomaron medidas antropométricas siguiendo las recomendaciones de la Sociedad Internacional para el Avance de la Antropometría (ISAK) y de composición corporal a través de la bioimpedancia tetrapolar. La ingesta calórica se midió mediante un recordatorio de 24 horas y para somnolencia diurna (SD)se utilizó el cuestionario de Epworth. Los análisis estadísticos se realizaron utilizando el software R. 56,5% de la muestra presenta SD, que afectó con mayor frecuencia a las mujeres en comparación con los hombres (p <0,05). Se encontraron diferencias entre las medidas corporales y la ingesta dietética entre grupos de personas con SD y sin ella. La ingesta calórica, la circunferencia de la cintura, el porcentaje de masa grasa fue mayor en personas con SD (p <0.05), mientras que la masa muscular fue mayor en sujetos sin SD (p <0.05). No se encontraron diferencias en relación con la grasa visceral. Concluimos que SD está relacionada con valores menos saludables en cuanto a ingesta dietética y medidas antropométricas(AU)
