RESUMO

PURPOSE: To describe adherence to sustainable healthy diets among a sample of 958 Chilean pre-schoolers (3-6 years) and explore associations between adherence and child and maternal sociodemographic and anthropometric characteristics. METHODS: Children's adherence to sustainable healthy diets was calculated from single multiple-pass 24-h dietary recalls using the Planetary Health Diet Index for children and adolescents (PHDI-C). Higher PHDI-C scores (max score = 150 points) represent greater adherence. Adjusted linear regression models were fitted to explore associations between PHDI-C scores and child and maternal characteristics. RESULTS: Children obtained low total PHDI-C scores (median 50.0 [IQR 39.5-59.8] points). This resulted from low consumption of nuts & peanuts, legumes, vegetables, whole cereals, and vegetable oils; a lack of balance between dark green and red & orange vegetables, inadequate consumption of tubers & potatoes and eggs & white meats, and excess consumption of dairy products, palm oil, red meats, and added sugars. Mean PHDI-C total score was significantly higher (50.6 [95%CI 49.6, 51.7] vs 47.3 [95%CI 45.0, 49.5]) among children whose mothers were ≥ 25 years compared to those with younger mothers. Positive associations were observed between scores for fruits and maternal education, vegetables and maternal age, added sugars and child weight status, while negative associations were observed between fruits and child age, and vegetable oils and maternal education. Scores for dairy products PHDI-C component were lower among girls. CONCLUSION: Adherence to sustainable healthy diets was low among this sample of Chilean children and was significantly associated with maternal age, being lower among children whose mothers were younger.

RESUMO

Background: Iron deficiency is one of the leading causes of anaemia, with those most affected being children and women of childbearing age, in Brazil there is a scarcity of studies involving the local prevalence of anaemia. Aim: To evaluate anaemia and associated factors in schoolchildren in Santa Cruz do Sul through the analysis of biochemical and haematological markers and parasitological examination of faeces. Subjects and methods: School children from 10 to 12 years of age were evaluated through complete blood count, serum ferritin, C-reactive protein and stool parasitological examination, as well as socio-demographic characteristics and prophylaxis with ferrous sulphate in childhood. Results: It was found that 13.0% of the population was anaemic, girls were very slightly overrepresented among the anaemic children. Only 5.3% had altered haematocrit levels; 26.6% had low Mean Corpuscular Volume levels; 18.4% had low ferritin levels; 2.4% had increased C-reactive protein levels, and 21.7% had altered eosinophils. As for the socioeconomic level, classes A2 and D presented lower haemoglobin levels, as well as class D presenting lower ferritin levels, although without statistical significance. Only 6.0% of the population presented iron-deficiency anaemia and 46.0% of the schoolchildren had used ferrous sulphate supplementation in childhood. Conclusion: The prevalence of anaemia in the studied municipality is low, probably due to the high municipal human development index. Epidemiological studies are essential to characterise the population in a systematic form, to prevent future problems.

RESUMO

In recent years, some new concepts have been added to asthma treatment such as "anti-inflammatory reliever" (ß2-agonist use associated to an inhaled corticosteroid (ICS) as a reliever treatment) that combines the benefits of both therapies and provides short- and long-term benefits for treatment in asthma patients. Robust evidence has been presented in patients over 12 years, and the main changes in the international guidelines for asthma treatment were originally made in this age group. However, a few suggestions have been added to treatments in younger patients, in part because of the scarce evidence that exists in this group. We aim to analyze the information regarding the utilization of ICS + fast-acting beta-agonist (FABA) combination in children between 6 and 11 years. Although up until today only three published trials exist (two studies use beclomethasone + albuterol and one study uses budesonide + formoterol), they provide significant information on the benefits of ICS + FABA use in this population.

RESUMO

Introduction: Leprosy, an infectious disease caused by Mycobacterium leprae, remains a public health concern in endemic countries, particularly in Brazil. In this study, we conducted an active surveillance campaign in the hyperendemic city of Castanhal in the northeastern part of the state of Pará using clinical signs and symptoms combined with serological and molecular tools to diagnose new cases and to identify drug resistance of circulating M. leprae strains and their distribution in the community. Methods: During an active surveillance of one week, we enrolled 318 individuals using three different strategies to enroll subjects for this study: (i) an active survey of previously treated cases from 2006 to 2016 found in the Brazil National Notifiable Disease Information System database (n = 23) and their healthy household contacts (HHC) (n = 57); (ii) an active survey of school children (SC) from two primary public schools in low-income neighborhoods (n = 178), followed by visits to the houses of these newly diagnosed SC (n = 7) to examine their HHC (n = 34) where we diagnosed additional new cases (n = 6); (iii) and those people who spontaneously presented themselves to our team or the local health center with clinical signs and/or symptoms of leprosy (n = 6) with subsequent follow-up of their HHC when the case was confirmed (n = 20) where we diagnosed two additional cases (n = 2). Individuals received a dermato-neurological examination, 5 ml of peripheral blood was collected to assess the anti-PGL-I titer by ELISA and intradermal earlobe skin scrapings were taken from HHC and cases for amplification of the M. leprae RLEP region by qPCR. Results: Anti-PGL-I positivity was highest in the new leprosy case group (52%) followed by the treated group (40.9%), HHC (40%) and lowest in SC (24.6%). RLEP qPCR from SSS was performed on 124 individuals, 22 in treated cases, 24 in newly diagnosed leprosy cases, and 78 in HHC. We detected 29.0% (36/124) positivity overall in this sample set. The positivity in treated cases was 31.8% (7/22), while in newly diagnosed leprosy cases the number of positives were higher, 45.8% (11/23) and lower in HHC at 23.7% (18/76). Whole genome sequencing of M. leprae from biopsies of three infected individuals from one extended family revealed a hypermutated M. leprae strain in an unusual case of primary drug resistance while the other two strains were drug sensitive. Discussion: This study represents the extent of leprosy in an active surveillance campaign during a single week in the city of Castanhal, a city that we have previously surveyed several times during the past ten years. Our results indicate the continuing high transmission of leprosy that includes fairly high rates of new cases detected in children indicating recent spread by multiple foci of infection in the community. An unusual case of a hypermutated M. leprae strain in a case of primary drug resistance was discovered. It also revealed a high hidden prevalence of overt disease and subclinical infection that remains a challenge for correct clinical diagnosis by signs and symptoms that may be aided using adjunct laboratory tests, such as RLEP qPCR and anti-PGL-I serology.

RESUMO

Objective: To analyze the agreement between body mass index (BMI) and waist-to-height Ratio (WHtR) to identify preschool and school children with cardiovascular risk factors (CRFs). Methods: Three-hundred-twenty-one kids were divided into preschool (3-5 years) and school children (6-10 years). BMI was used to classify children as overweight or obese. Abdominal obesity was defined with a WHtR ≥0.50. Fasting blood lipids, glucose and insulin were measured, and the homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. The presence of CRFs and multiple non-waist circumference (non-WC) metabolic syndrome factors (MetS-Factors) [high HOMA-IR, high triglycerides and low high-density lipoprotein cholesterol (HDL-C)] were analyzed. Results: One-hundred-twelve preschool and 209 school children were evaluated. WHtR ≥0.50 classified abdominal obesity in more than half of the preschool children, exceeding those classified with overweight+obesity by BMI (59.5% vs. 9.8%; p<0.001). There was no agreement between WHtR and BMI to identify preschool kids with CRFs and multiple non-WC MetS-Factors (kappa: 0.0 to 0.23, p>0.05). There were similar proportions of school children classified with abdominal obesity by the WHtR and overweight+obesity by the BMI (18.7% vs. 24.9%; p>0.05). There was substantial agreement between WHtR and BMI to identify school children with high total cholesterol values, low-density lipoprotein cholesterol (LDL-C), triglycerides, non-HDL-C, insulin, HOMA-IR, low HDL-C values, and the presence of multiple non-WC MetS-Factors (kappa: 0.616 to 0.857, p<0.001). Conclusion: In preschool children WHtR ≥0.5 disagree with BMI results, but in school kids, it has good agreement with the BMI to classify the children´s nutritional status and to identify those with CRFs.

Objetivo: Analizar el grado de acuerdo entre el índice de masa corporal (IMC) y la relación/cintura estatura (rCE) para identificar niños con factores de riesgo cardiovascular (FRC). Métodos: Estudio transversal analítico con 112 niños preescolares (3-5 años) y 209 escolares (6-10 años). El sobrepeso y la obesidad se clasificaron con el IMC y la obesidad abdominal con la rCE ≥0.50. Se tomaron muestras sanguíneas en ayuno para análisis de glucosa, insulina, lípidos y cálculo del índice HOMA-IR. Se analizó la presencia de FRC y de múltiples factores del síndrome metabólico (Factores-SinMet) diferentes a la cintura [HOMA-IR elevado, triglicéridos elevados y colesterol de alta densidad (HDL-C) bajo]. Resultados: rCE ≥0.50 clasificó con obesidad abdominal a más de la mitad de los niños preescolares, excediendo el número de niños clasificados con sobrepeso+obesidad por IMC (59.5% vs 9.8%; p<0.001). No hubo acuerdo entre el IMC y la rCE para identificar niños preescolares con FRC o múltiples Factores-SinMet diferentes a la cintura (kappa: 0.0 a 0.23, p>0.05). Fueron similares las proporciones de niños escolares clasificados con obesidad abdominal por la rCE o con sobrepeso+obesidad por el IMC (18.7% vs. 24.9%; p>0.05). Hubo acuerdo sustancial entre la rCE y el IMC para identificar niños escolares con valores elevados de colesterol total, colesterol de baja densidad, triglicéridos, colesterol no-HDL, insulina, HOMA-IR, valores bajos de HDL-C y la presencia de múltiples Factores-SinMet diferentes a la cintura (kappa: 0.616 a 0.857, p<0.001). Conclusión: En niños preescolares la aplicación de rCE ≥0.5 no presenta acuerdo con el IMC, pero en escolares presenta un acuerdo sustancial con el IMC en la clasificación del estado nutricional y en la identificación de niños con FRC.

RESUMO

PURPOSE: The benefits of a healthy diet on children´s cognition have been described in several studies. However, many previous studies have analyzed the effect on general cognitive domains (e.g. intelligence), used measures based almost exclusively on local examinations, and rarely consider social context. OBJECTIVE: The objective of the present study was to examine the relationship between two diet patterns and contextualized cognitive performance measures of children aged 6-8 years from low-average income neighborhoods in Montevideo, Uruguay. METHODS: 270 first-grade children with complete data participated in the study. Consumption of foods was determined via two averaged 24-h dietary recalls with the mother. Two dietary patterns were identified via principal component analysis: "processed (high calorie) foods" and "nutrient dense". Children´s cognitive performance, including general cognitive abilities, achievement in mathematics and reading, and discrepancy scores between predicted and actual achievement was assessed with the Woodcock-Muñoz Cognitive and Achievement scales. The association of dietary patterns and cognitive endpoints was analyzed in multilevel models, clustered by children´s school. Sociodemographic and biological variables were used as covariates. RESULTS: The nutrient dense foods pattern, characterized by higher consumption of dark leafy and red-orange vegetables, eggs, beans & peas, potatoes, was associated with better performance in reading, with beta coefficient 3.28 (95% CI 0.02, 6.54). There was also an association between the nutrient dense foods factor and the Discrepancy in reading, 2.52 (0.17, 4.87). Processed (high calorie) foods pattern, characterized by higher consumption of breads, processed meats, fats and oils, sweetened beverages, and sweetened yogurt/dairy products; reduced intake of milk, pastries and pizza dinners was not associated with cognitive performance. CONCLUSIONS: Nutrient dense food pattern was positively associated with children's reading achievement. A nutrient-rich diet may benefit written language acquisition at the beginning of schooling.

RESUMO

BACKGROUND: Previous studies found high prevalence of inadequate intakes of vitamins E, D and K, calcium and potassium among Brazilian pre-school children, with suboptimal consumption of dairy products. Dietary modelling was applied to determine the theoretical impact of improving dairy products consumption on nutrient adequacy in 4-5-year-old Brazilian children. METHODS: Adherence to the dairy recommendation of two servings/day was calculated using data from the Brazil Kids Nutrition and Health Study (KNHS) (n = 228). Two modelling scenarios were applied to test the impact on nutrient intakes of (1) adding one or two servings of a frequently consumed cow's milk or a widely available fortified alternative: pre-school children milk (PCM), and of (2) substituting the current milk consumed by PCM. Mean nutrient intakes and percentage of children adhering to the nutrient recommendations were determined at baseline and after applying modelling scenarios. RESULTS: Seventy-six percent (n = 174) of children did not meet the recommended daily two servings of dairy products, 56% had less than one serving of dairy products on the day of recall. The mean consumption of whole milk (fortified and unfortified) was 147 g/d, yoghurt 114 g/d and cheese 34 g/d. The addition of one serving of cow's milk demonstrated a 17% reduction in calcium inadequacy, 18% reduction in vitamin A and 3% reduction in zinc inadequacy. Adding one serving of PCM further reduced calcium inadequacy from 87 to 41%, vitamin E from 81 to 37%, and zinc inadequacy by 10%. Replacing the child's current milk with a PCM resulted in further reduction of micronutrient inadequacies, including calcium, vitamin D and vitamin E. CONCLUSIONS: Dairy products consumption in pre-school children should be encouraged to reduce nutrient inadequacies. In particular, consumption of PCM would help to reduce calcium, vitamin D and vitamin E inadequacy, nutrients of concern in this population.

RESUMO

Eighty-five percent of the studies of patients with congenital hypothyroidism (CH) treated with Levothyroxine (L-T4) report neuropsychological sequelae throughout life. In neonates and infants, there is a deficit in sensorimotor skills (impaired balance). In preschool and elementary school children and adolescents, there are alterations in intellectual quotient (low scores), language (delayed phonological acquisition), memory (visual, verbal, visuospatial, visuoconstructive, autobiographical, and semantic), sensorimotor skills (impaired fine and gross motor control), and visuoconstructive-visuospatial domain (low scores in spatial location, block design, and object assembly). These neuropsychological domains are also affected in young adults, except for language (adequate verbal fluency) and visuoconstructive-visuospatial domain (no data). The onset and severity of neuropsychological sequelae in patients with treated CH depend on several factors: extrinsic, related to L-T4 treatment and social aspects, and intrinsic, such as severity and etiology of CH, as well as structural and physiological changes in the brain. In this review, we hypothesized that thyroid hormone hyposensitivity (THH) could also contribute to neuropsychological alterations by reducing the effectiveness of L-T4 treatment in the brain. Thus, further research could approach the THH hypothesis at basic and clinical levels to implement new endocrinological and neuropsychological therapies for CH patients.

RESUMO

El inicio de buenos hábitos alimenticios en el aspecto nutricional contribuye en el desarrollo del niño escolar, evitando con ello, la anemia la cual se estima que posee un impacto a nivel mundial de 600 millones de niños que padecen de esta enfermedad según datos registrados por la Organización Mundial de la Salud. Con este estudio se busca demostrar los hábitos alimenticios, calidad nutricional y concentración de hierro sérico en estudiantes con anemia por deficiencia de hierro en el Cantón Jipijapa en Ecuador. La metodología empleada en el análisis del estudio fue de tipo descriptiva observacional, de corte transversal. Para ello, se aplicó un muestreo no probabilístico voluntario, se contó con la participación de 63 escolares del Cantón con previa autorización. Entre los resultados se encontraron que en los 63 escolares predomina el consumo diario (76,4%) en los hábitos alimenticios, mientras tanto que en la calidad nutricional se observó poco saludable (24 y 37 ME) en ciertos alimentos necesarios para el consumo estudiantiles en los rangos establecido, en la anemia se obtuvo un resultado de (10,2%) de escolares con anemia, mientras que para la deficiencia de hierro el (11,1%) de los niños. Se concluye que en los escolares es prevalente los malos hábitos alimenticios, sin embargo, hay casos en los que escolares muestran anemia con deficiencia de hierro y escolares sin anemia con déficit del mismo lo que es elemental las practicas alimenticia tanto en los hábitos como en la calidad nutricional.

The initiation of good nutritional eating habits contributes to the development of school children, thus avoiding anemia, which is estimated to have a worldwide impact of 600 million children suffering from this disease according to data recorded by the World Health Organization. This study seeks to demonstrate the dietary habits, nutritional quality and serum iron concentration in students with iron deficiency anemia in the Jipijapa Canton in Ecuador. The methodology used in the analysis of the study was descriptive observational, cross-sectional. For this purpose, a voluntary non-probabilistic sampling was applied, with the participation of 63 schoolchildren from the Canton with previous authorization. Among the results, it was found that in the 63 schoolchildren there was a predominance of daily consumption (76.4%) in eating habits, while in nutritional quality, unhealthy was observed (24 and 37 ME) in certain foods necessary for student consumption in the established ranges, in anemia a result of (10.2%) of schoolchildren with anemia was obtained, while for iron deficiency (11.1%) of the children. It is concluded that bad eating habits are prevalent in schoolchildren, however, there are cases in which schoolchildren show anemia with iron deficiency and schoolchildren without anemia with iron deficiency, which is elementary in the nutritional habits as well as in the nutritional quality.

RESUMO

Although the interaction between anxiety and attention is considered crucial for learning and performance in mathematics, few studies have examined these cognitive and affective predictors in a single framework or explored the role of sustained attention in promoting children's arithmetic performance, using traditional linear analyses and latent profile analysis (LPA). In this paper, state anxieties (in a math test and in an attention test situation), general anxiety traits, sustained attention (performance-based test and attention deficit/hyperactivity disorder (ADHD) self-ratings) and math achievement of 403 fourth and fifth graders (55.8% girls) were assessed. A negative correlation between state anxiety prior to the math test and arithmetic achievements was identified, even when controlling for other non-math related state anxieties and general anxiety. Sustained attention was a strong predictor of arithmetic achievement and functioned as a moderator in the anxiety-performance link. LPA identified six distinct profiles that revealed a complex relationship with arithmetic fluency. The weakest achievement was found for a specific math anxiety subgroup. The findings highlight the important role of the interaction of anxiety and sustained attention in children's ability to perform math and enable new conclusions about the specific nature of math anxiety. Implications for future research are discussed.

RESUMO

Overweight and obesity in Mexican elementary school children increased ten percentage points in the last 30 years; one of the factors attributed is inadequate dietary quality. The objective of this study was to evaluate the association of monounsaturated fat intake with abdominal obesity and nutrient intake and obesity and overweight with dietary quality of elementary school children from Northwest Mexico. A cross-sectional study was conducted with 218 first grade elementary school children. A socioeconomic survey and two nonconsecutive 24-HR were applied, and anthropometric measurements were taken. Dietary quality was evaluated and classified as: healthy, medium and poor. Children consumed fewer servings of fruits, vegetables, legumes, dairy products and water than recommended by the Mexican food guidelines. A negative association was found among monounsaturated fat intake and abdominal obesity (p = .032). Only 1.4% of the children presented healthy dietary quality, 44.5% showed a medium dietary quality, and 54.1% had poor dietary quality. Poor dietary quality was associated with a lower intake of fiber (p = .002), protein (p = .002), potassium (p = .001) and vitamin E (p = .002). Elementary school children from Northwest Mexico have inadequate dietary quality that compromises their nutritional and health status, while monounsaturated fat intake could be a protective factor for abdominal obesity.

RESUMO

Recent findings on the negative impacts of math anxiety (MA) have raised questions for educational and clinical research regarding effective intervention programs. One basic approach for developing intervention programs in the field of cognitive behavioral therapy is to gain an in-depth understanding of the cognitive beliefs of children with a specific mental problem. By applying latent profile analysis (LPA), the present study aimed at identifying different patterns of MA and providing further insights into its cognitive phenomenology. For this purpose, trait-MA, state-MA, attitudes toward math, academic self-concepts, fixed/growth mindsets, executive functions, and math performance of 475 fourth and fifth graders (48.2% girls) were assessed. LPA indicated seven distinct profiles characterized by different dimensions and patterns of state-MA, trait-MA, and core beliefs toward math. Furthermore, the profiles showed clearly different math performances. The weakest performances were found for a profile with highest state-MA, high trait-MA, and negative cognitive beliefs toward math and a profile with average state-MA, high trait-MA, and negative cognitive beliefs toward math, whereas the highest achieving profile had no state-MA, high trait-MA, and very positive cognitive beliefs toward math. The findings underline the complexity of MA and emphasize the necessity to develop interventions with careful consideration of the heterogeneous patterns.

RESUMO

Abstract Present study was conducted among school children to recognize the prevalence of IPIs in rural communities of district Dir Lower, Pakistan. A sum of 324 samples of stool were collected (210 boys and 114 girls). Used direct smear method and formol ether sedimentation concentration technique for processing the samples. The result shows that 82% (n=266) were found infected comprised 64.8% male and 35.1% females. Children of the age group 10 to 12 years were found extremely infected 94.2% while 4-6 year age group were having minimum ratio of infection 72%. Current study shows mono parasitism in 50.6% of the students while 22.2% were infected with 2 species and 7.40% were infected with three species of parasites. Seven species of intestinal parasites were reported include Ascaris lumbricoid in male (n=122) 58.0% and in female (n=65) 57.0% followed by Hook worm (n=88) 41.9% and (n=44) 38.5%; Tania saginata (n=44) 20.9% and (n=24) 21.0%; Entrobius vermicularis (n=32) 15.2% and (n=16) 14.0%; Trichuris trichura (n=25) 11.9% and (n=22) 19.2%; Hymenolepis nana (n=24) 11.4% and (n=18) 15.7% and Entameoba histolytica (n=16) 7.61% and (n=14) 12.2% in male and females respectively. The study indicates that most occurring intestinal parasite in the current study were Ascaris lumbricoides 58.0% (n=122) followed by hookworms 41.9% (n=88). Male students were more infected than females in the present study.

RESUMO

Abstract Tapeworms of zoonotic importance have been described as a leading public health problem. Current research was aim to assess the prevalence of tapeworms among 5-12years school children residing in district Lower Dir, Pakistan from January 2019-December 2019. The wet mount preparation in saline/iodine/methods were used for stool examination. Data was analyzed using appropriate descriptive, static methods. Of the 400 children studied 71.7% were infected with one or more species of intestinal parasites. Single infection of cestode species was found in 69 individuals with 17.2% prevalence and multiple parasitic infections were identified in 19.7% (n=79/400) individuals. The multiple infection were comprised as 10% (n=40) double, 6.75% (n=27) triple and 3% (n=12) quadruple. A total of 9 species of helminths and one species of protozoan infection. Among the helminths Ascaris lumbricoides was the most prevalent 33.1% (n=95), Taenia saginata 22.6% (n=65), hookworm 19.8% (n=57), Hymenolepis nana 18.8% (n=54), Enterobius vermicularis and Hymenolepis diminuta 1.39% (n=4each), Trichuris trichura 1.04% (n=3), Toxocara spp 0.69% (n=2) and Schistosoma japonicum 0.34% (n=1) were reported. One protozoan species was Cryptosporidium spp 0.69% (n=2) in current study. In case of A.lumbricoides, hookworm, E.vermicularis, T.trichura, T.saginata, H.nana and H.diminuta the male children of below 8 years of age were highly infected. Other infections are reported in the same prevalence with slight difference if any. We conclude that there is a need for mass scale campaigns to create awareness regarding health and hygiene in children and the need for development of effective poverty control programs because deworming alone is not adequate to control parasitic infections.

RESUMO

SUMMARY: Prevention and correction of overweight in children and adolescents is also very important for many reasons. According to previous research, the problem tends to vary according to sex, and different ages and the lifestyle in rural and urban areas has changed drastically in recent years and decades. Regarding the above-mentioned, the main goal of this research was to determine the nutritional status of young school children in urban and rural areas of Montenegro in relation to sex and age. The sample in this research has consisted of children aged 6 and 9 (younger school age). The total sample in this research is 800 male and female children who belong to the urban and rural areas of Montenegro. The sample of variables used in this study was: body mass index-percentile values (BMI), and waist circumference and body height ratio (WHtR) which were used as indicators to assess nutritional status. Based on obtained results it could be generally concluded that there are no statistically significant differences in nutritional status between primary school children from urban and rural areas of Montenegro, which is the opposite of what was expected based on previous research, but also which is very important since all subjects in the future can be treated as homogeneous groups when it comes to the impact of environment and lifestyle on the nutrition status of younger school children. On the other hand, it is important to emphasize that the main limitation of this research is that measurements were carried out in the middle of the COVID-19 pandemic, and the recommendation could be that after the end of the pandemic, special "COVID teams" should be formed, which would consist of experts from various fields of physical culture, sports, and medicine, all with the aim of influencing possible problems with nutritional status and physical activity of young school children caused by a pandemic.

RESUMEN: La prevención y corrección del sobrepeso en niños y adolescentes es muy importante por muchas razones. Según investigaciones previas, el problema tiende a variar según el sexo, las diferentes edades y el estilo de vida en las zonas rurales y urbanas ha cambiado drásticamente en los últimos años y décadas. Con respecto a lo mencionado anteriormente, el objetivo principal de esta investigación fue determinar el estado nutricional de los niños pequeños en edad escolar en áreas urbanas y rurales de Montenegro en relación con el sexo y la edad. La muestra en esta investigación ha estado compuesta por niños de 6 y 9 años (menor edad escolar). La muestra total en esta investigación fue de 800 niños y niñas que pertenecían a las zonas urbanas y rurales de Montenegro. La muestra de variables utilizadas en este estudio fue: índice de masa corporal-valores percentiles (IMC), circunferencia de la cintura y relación talla corporal (RCCE), los cuales se utilizaron como indicadores para evaluar el estado nutricional. Sobre la base de los resultados obtenidos, se pudo concluir en general que no existen diferencias estadísticamente significativas en el estado nutricional entre los niños de primaria de las zonas urbanas y rurales de Montenegro, que es lo contrario de lo que se esperaba en base a investigaciones anteriores, pero que también es muy importante, ya que todos los temas en el futuro pueden ser tratados como grupos homogéneos en lo que respecta al impacto del medio ambiente y el estilo de vida en el estado nutricional de los niños en edad escolar más pequeños. Por otro lado, es importante recalcar que la principal limitación de esta investigación fue que las mediciones se realizaron en plena pandemia de COVID-19, y la recomendación podría ser que luego de finalizada la pandemia, equipos especiales "COVID", que estaría integrado por expertos de diversas áreas de la cultura física, el deporte y la medicina, todo ello con el objetivo de incidir en los posibles problemas del estado nutricional y de actividad física de los jóvenes escolares provocados por una pandemia.
