Association between early childhood caries and nutritional status in children in a peruvian social program: a cross-sectional study / Asociación entre caries de la primera infancia y estado nutricional en niños de un programa social peruano: un estudio transversal

Introduction: Early childhood caries is still very prevalent, mainly in developing countries, and it is related to the quality of life of children due to early tooth loss. Objective: The study objective was to determine the association between dental caries and its clinical consequences on nutritional status in children of the "Vaso de Leche (Glass of Milk)'' social program, in Puno City, Peru, during the year 2020. Materials and Methods: An observational, descriptive-correlational, cross-sectional study; the sample consisted of 740 children between 1 and 5 years old who met the selection criteria; the clinical consequences of untreated dental caries were evaluated using the PUFA index and the prevalence of caries with def-t; the nutritional status was determined by the weight and height of the child according to protocols (NTS No. 357 - MINSA /2017/ DGIESP); the data were analyzed with the SPSS-v25 program, the association between variables was evaluated with the chi-square test, Mann-Whitney U test and Spearman's Rho test, considering significance at a p-value <0.05. Results: No significant relationship was found when dental caries was evaluated with the nutritional condition (p<0.05). However, when the def-t index values were related to the nutritional condition of the children, a significant difference was found (p<0.05). There was no significant difference with the PUFA index (p>0.05). Conclusions: There is no association between early childhood caries and nutritional status in children aged between 3 and 5 years; however, a significant relationship was found between the values of the def-t index and the nutritional status of the children.

Introducción: La caries infantil temprana sigue siendo muy prevalente, principalmente en los países en desarrollo, y está relacionada con la calidad de vida de los niños debido a la pérdida temprana de dientes Objetivo: El objetivo del estudio fue determinar la asociación entre la caries dental y sus consecuencias clínicas sobre el estado nutricional en niños del programa social "Vaso de Leche", en la ciudad de Puno, Perú, durante el año 2020.

Resultado: No se encontró relación significativa cuando se evaluó la caries dental con la condición nutricional (p<0,05). Sin embargo, cuando los valores del índice d-t se relacionaron con la condición nutricional de los niños, se encontró una diferencia significativa (p<0,05). No hubo diferencia significativa con el índice PUFA (p>0,05). Conclusión: No existe asociación entre caries de la primera infancia y el estado nutricional en niños de 3 a 5 años; sin embargo, se encontró una relación significativa entre los valores del índice d-t y el estado nutricional de los niños.

Nasolabial anthropometry using 3D computed tomography scan reconstruction: baseline study for nasolabial correction in Indonesian children with cleft lip and palate / Antropometría nasolabial mediante reconstrucción con tomografía computarizada 3D: estudio de referencia para la corrección nasolabial en niños Indonesios con fisura labiopalatina

Background: The normal nasolabial structure of infants and chil-dren from East Asian, specifically Indonesian, descent groups has been less explored in the literature. This anthropometric study is used as a guide in lip repair in patients with clefts. This retrospective study used archived CT images from the Indonesian population. Materials and Methods: Computed tomography records of children under 5 years of age were extracted from a provincial hospital. The images were then filtered based on the inclusion and exclusion criteria and then the 2D slices were reconstructed using the open source software Invesalius. Twenty-five variable nasolabial parameters of the nasolabial structure were then measured in the 3D rendering mode. Images with craniofacial dysmorphism or cannulas that passed over the nasolabial structure were excluded. Results were summarized using descriptive statistics. Results: Fourteen of 128 CT images were included in this study. The samples were divided into two age groups: 0-12 months and 25-54 months. There were moderate to strong, positive correlations between age and all nasolabial variables, which were statistically significant (p<0.05) except for nasal length, nares circumference, columella width, superior philtrum width, philtrum column height, and cutaneous upper lip height. Conclusions: This study described anthropometric measurements of normal nasolabial structures as a reference point for lip correction surgery. However, to obtain more accurate anthropometric guidelines, further studies with larger sample sizes are desirable. Although surgical repair of the lip is usually performed within the first year of life, some cases of surgery are performed after infancy.

Antecedentes: La estructura nasolabial normal de bebés y niños de grupos de ascendencia de Asia oriental, específicamente de Indonesia, ha sido menos explorada en la literatura. Este estudio antropométrico se utiliza como guía en la reparación del labio en pacientes con fisuras. Este estudio retrospectivo utilizó imágenes de tomografía computarizada archivadas de la población indonesia. Materiales y Métodos: Se extrajeron los registros de tomografía computarizada de niños menores de 5 años de un hospital provincial. Luego, las imágenes se filtraron según los criterios de inclusión y exclusión y luego se reconstruyeron los cortes 2D utilizando el software de código abierto Invesalius. Luego se midieron veinticinco parámetros nasolabiales variables de la estructura nasolabial en el modo renderizado 3D. Se excluyeron imágenes con dismórfica craneofacial y cánula que pasa sobre la estructura nasolabial. Los resultados se resumen mediante estadística descriptiva. Resultado: En este estudio se incluyeron catorce de 128 imágenes de TC. Las muestras se dividieron en dos grupos de edad: 0-12 meses y 25-54 meses. Hubo una correlación positiva de moderada a fuerte entre la edad y todas las variables nasolabiales, que fueron estadísticamente significativas (p<0,05) excepto la longitud nasal, la circunferencia de las narinas, el ancho de la columela, el ancho del filtrum superior, la altura de la columna del filtrum y la altura cutánea del labio superior. Conclusión: Este estudio describió las medidas antropométricas de estructuras nasolabiales normales como base para la cirugía de corrección de labios. Sin embargo, para obtener directrices antropométricas más precisas, son deseables más estudios con tamaños de muestra más grandes. Aunque la reparación quirúrgica del labio normalmente se realiza dentro del primer año de vida, en algunos casos la cirugía se realiza después de la infancia.

The main clinical manifestations were abdominal pain（20/31，64.52%），vomiting（11/31，35.48%），hematochezia（7/31，22.58%），and diarrhea（7/31，22.58%）.The children with eosinophilic duodenitis and eosinophilic colitis were more likely to have abdominal pain, with an incidence of 83.33%(10/12)（ P<0.05）. Eosinophilia increased in 70.97%（22/31）of children，which was more common in children >3 years of age（88.24% vs. 50.00%， P<0.05）.Anemia was seen in 29.03%（9/31）of the patients，and it was more common in children under 3 years of age（50.00% vs. 11.76%， P<0.05）.Hypoalbuminemia was found in 22.58%（7/31）of patients. Specific IgE（sIgE）was positive in 73.33%（22/30）of children. Milk，egg，and wheat were the most common allergens. Gastrointestinal endoscopy showed mucosal edema（29/31，93.55%），erythema（26/31，83.87%），roughness（12/31，38.71%），ulcer（10/31，32.26%），et al.All children were treated with the elimination diet. Besides,10 cases were treated with omeprazole, 16 cases were treated with montelukast, and 17 cases were treated with glucocorticoid. The incidence of relapse or steroid resistance was 32.26%（10/31），and 70.00%（7/10）of them occurred within one year of treatment. Conclusion:Eosinophilic gastroenteritis in children under 6 years of age may involve single or multiple sites.Abdominal pain is the most common clinical manifestation. Children may have elevated peripheral blood eosinophils，anemia，or hypoalbuminemia.Most children have food allergens. Nearly one-third of children experience relapse or steroid resistance.

A study of the sleep status of preschool children with a coordination development disorder / 中华物理医学与康复杂志

Objective:To investigate the sleep status of preschool children with a coordination development disorder (DCD).Methods:Implementing stratified cluster sampling, 38, 900 questionnaires were distributed in 1000 classes of 200 kindergartens randomly selected in 11 prefecture-level cities of China′s Zhejiang Province. A total of 35, 464 valid responses were returned. On the basis of the responses, 2251 of the children were of (6.35%) were deemed DCD-positive, while the rest formed a DCD-negative group. The Children′s Family Social Environment and Sleep Health Questionnaire (1-6 years old) and the children′s sleep habits questionnaire were employed to investigate their sleep status.Results:①Regular sleeping time and duration, and falling asleep within 20 minutes were significantly less common in the DCD-positive group. In the negative group, shifting sleep place at night, finding it hard to sleep in strange environments, waking up ≥2 times a night, being awoken by others in the morning, difficulty in waking up and getting up in the morning, and bad mood after waking were significantly less frequent. ②In addition to delayed bedtime, the incidence of refusal to go to bed, fear of sleeping in the dark or alone, bedwetting, restless sleep, sleepwalking, talking in sleep, being awakened by nightmares, teeth grinding, loud snoring, apnea, dyspnea, crying and sweating after waking up at night, and insufficient sleep were all significantly higher in the DCD-positive group. ③The DCD-positive group also reported more sleeping in the daytime on weekends, more time on playing electronic products along with shorter sleep duration at night. There was, however, no significant difference between the two groups in sleep duration on school days and all day on weekends.Conclusion:Preschool children with a DCD have different sleep habits from those developing normally. They are more likely to suffer from sleep problems which affect their sleep duration.

Status quo of screen exposure and its determinants in 3- to 6-year-old children in Minhang district, Shanghai / 中国儿童保健杂志

【Objective】 To investigate the screen exposure status in 3- to 6-year-old children in Minhang district and to analyze its determinants, so as to provide a basis for scientific intervention of screen exposure in children. 【Methods】 A total of 1 035 children aged 3 to 6 years were selected from 30 classes in 10 kindergartens in Minhang district by multi-stage cluster sampling in October 2022. An online questionnaire survey was conducted by their parents. Screen exposure was difined as spending more than one hour on video products per day. Multivariate Logistic regression model was adopted to analyze the determinants of children screen exposure. 【Results】 Among 1 035 children, 730 experienced screen exposure (70.53%). The average time of daily screen exposure was (1.67±0.98)h. The daily screen exposure time of children aged 3, 4, 5 and 6 years at weekends was (1.77±1.13), (1.76±1.04), (1.98±1.10)h and(2.08±1.22)h, respectively, and the difference was statistically significant (F=3.98, P2hours/day (OR=2.10, 95%CI:1.35 - 3.27) when accompanying children, parents supporting children using video products(OR=1.59, 95%CI:1.17 - 2.15), children using video products before bedtime(OR=1.94, 95%CI:1.32 - 2.86), and unsupervised use of video products for children(OR=1.94, 95%CI:1.36 - 2.77) were independent risk factors for children′s screen exposure(P<0.05). Father′s education level of bachelor(OR=0.61,95%CI:0.43 - 0.89), master and above(OR=0.49, 95%CI:0.34 - 0.73) was a protective factor for children′s screen exposure(P<0.05). 【Conclusions】 Attention should be paid to the problem of screen exposure of 3 -to 6 - year-old children. Targeted efforts should be made to popularize the knowledge of the harm of early screen exposure to children among caregivers, caregivers are advocated for the rule formulation of screen behavior, scientifically regulate children′s screen exposure behaviors, and increase parent-child communication, so as to reduce the adverse effects of screen exposure on children′s health.

Reference values for inspiratory muscle related indexes of preschool children in Nanjing / 中国儿童保健杂志

【Objective】 To generate reference values for inspiratory muscle of preschool children in Nanjing, so as to provide a reference index for evaluating children′s lung function and exercise performance. 【Methods】 A total of 236 preschool children were selected from the main urban area of Nanjing by stratified cluster sampling.The inspiratory muscles were evaluated by breath link respiratory function evaluation system to obtain the maximum inspiratory pressure (MIP) and inspiratory peak flow rate.Pearson analysis was used to determine the correlation of MIP and inspiratory peak flow rate with gender, age, height and weight.Multiple linear stepwise regression analysis was used to obtain the formula of MIP and inspiratory peak flow rate. 【Results】 Differences in MIP and peak inspiratory flow rate were not significant between boys and girls (P>0.05), but were statistically significant among different age groups and showed an increasing trend with age (F=13.660, 33.581, P<0.001).MIP and peak inspiratory flow rate were positively correlated with children′s age, height and weight (P<0.001).The regression model, proved to be statistically significant(F=12.913、22.398, P<0.08), indicated that height was the best predictor of MIP and age was the best predictor of inspiratory peak flow rate. 【Conclusions】 This study is the first study on the predicted value of inspiratory muscle in preschool children in China.The predicted value formula can provide a reference for clinical inspiratory muscle evaluation.

Characteristics of sensory integration in static balance of 4 - to 5-year-old children / 中国儿童保健杂志

【Objective】 To analyze the sensory integration characteristics of 4- to 5-year-old preschool children while maintaining static balance, in order to provide reference for promoting the development of motor development. 【Methods】 A total of 128 preschool children were randomly selected in this study from a public kindergarten in Suzhou. Wearable sensor were worn at the center of mass(COM) position for four tests: T1 standing with eyes open, T2 standing with eyes closed, T3 standing with eyes open on a sponge pad, and T4 standing with eyes closed on a sponge pad. The angular velocity modulus(ω) of COM shaking was extracted, the Romberg quotient(RQ), vestibular Romberg quotient(VRQ), and the rate of increase in body stability when integrating different sensations were calculated. The contribution weights and sensory integration characteristics of visual, proprioceptive, and vestibular sensations to static balance were analyzed. Independent sample t-test was used to analyze the differences between different gender and age groups. 【Results】 The RQ was 1.20, and the VRQ was 1.58. The contribution rates of visual, proprioceptive, and vestibular senses to body balance were approximately 9.28%, 28.19% and 62.53%, respectively. The difference in the rate of increase in body stability between integrated vision and integrated proprioception with normal vestibular perception was statistically significant(P0.05) and the difference in half year old age was not statistically significant(P>0.05). 【Conclusions】 When preschool children aged 4 - 5 maintain static balance, the contribution of vestibular integration proprioception to body stability is greater than that of vestibular integrate vision. The contribution of vestibular and visual integrate proprioception to body stability is greater than that of vestibular and proprioception integrate vision. The sensory integration characteristics between boys and girls, as well as half year old children, are basically the same.

Then the prevalence rate of overweight and obesity was determined by physical measurements. A case-control study was conducted with a questionnaire survey of 3 786 children(1 893 in the obesity group and 1 893 in the control group) to analyze the factors influencing preschool obesity. 【Results】 1) The overall detection rates of overweight among preschool children in Suzhou was 14.8%(boys 14.6%, girls 15.0%). The overall detection rates of obesity was 7.9%(boys 8.7%, girls 7.1%), with a statistically significant difference between boys and girls(χ2=19.828, P<0.01). 2) There was statistically significant difference in the detection rates of obesity among different age groups(χ2=98.415, P<0.01), with the lowest rate in the 3 - 4 years old group(5.8%) and the highest rate in the 6 - 7 years old group(11.8%). 3) The overall detection rates of mild, moderate and severe obesity was 4.8%, 2.6% and 0.5%, respectively. The proportion of moderate and severe obesity significantly increased with age(χ2=57.275, P<0.01). 4) Risk factors for preschool obesity included birth weight >4 000g, cesarean section, parental overweight/obesity, strong appetite of children, eating speed <10min/meal, high frequency of fried food consumption(>1time/week), eating while watching television, sedentary behavior >2h/d, insufficient exercise endurance, screen time >1h/d, and late bedtime(after 21∶30)(P<0.05). Protective factors for preschool obesity included larger breakfast consumption, fruits and vegetables as regular snacks, and physical activity after meals(P<0.05). 5) Factors influencing the degree of preschool obesity included paternal overweight(OR=1.33, 95%CI:1.06 - 1.65), paternal obesity(OR=1.91, 95%CI:1.46 - 2.49), maternal overweight(OR=1.25, 95%CI:1.01 - 1.54), maternal obesity(OR=1.94, 95%CI:1.40 - 2.69), low education level of father(junior high school or below)(OR=1.57, 95%CI:1.25 - 1.96), strong appetite of children(OR=1.72, 95%CI:1.41 - 2.11), eating speed <10min/meal(OR=1.29, 95%CI:1.05 - 1.57), sedentary behavior >2h/d(OR=1.51, 95%CI:1.24 - 1.85), insufficient exercise endurance(OR=1.56, 95%CI:1.12 - 2.19), and screen time>1h/d(OR=1.42, 95%CI:1.16 - 1.75). 【Conclusions】 The detection rates of overweight and obesity among preschool children in Suzhou are relatively high, and the detection rate and severity of obesity increase with age. In addition to genetic factors, preschool obesity are also associated with pregnancy and birth history, as well as unhealthy lifestyle after birth.

Effect of intervention on the perception of body weight among parents of preschool children / 中国儿童保健杂志

【Objective】 To explore the effect of health education intervention measures on improving parents′ perception of their children′s weight, so as to provide scientific basis for intervention in preschool obese children. 【Methods】 Children from 7 kindergartens in Luohu district were randomly selected in this study in October 2020, and were divided into intervention group and control group. The intervention group consisted of 1 318 children and parents from 3 kindergartens, and the control group consisted of 1 546 children and parents from 4 kindergartens. Parents in the intervention group received combination of online and offline health education intervention measures for 2 months, while parents in the control group received no intervention measures. Logistic regression analysis was used to evaluate the effect of parents′ perception of their children′s weight in intervention group and control group. 【Results】 After controlling for imbalanced variables such as parents′ education level, total monthly family income, and parents′ perception of their children′s weight, there was a statistically significant difference in the improvement of parents′ perception of their children′s weight status between two groups after intervention(OR=2.175, 95%CI: 1.536 - 3.080, P0.05). Regardless of whether the child′s weight status was normal or not, parents in the intervention group showed better improvement in their perception of their children′s weight status than the control group(OR=1.558, 6.111, 95%CI:1.025 - 2.368, 2.811 - 13.287, P<0.05). 【Conclusion】 Health education measures can improve the perception bias of parents towards their preschool children′s weight, and the intervention effect varies among children of different genders and weight states.

Hotspots and trends of nutrition research in global preschool children from 2012 to 2022 based on Citespace visual analysis / 中国儿童保健杂志

【Objective】 To review the scientific research advances in the field of preschool children′s nutrition from 2012 to 2022, in order to provide reference for relevant policy formulation and further scientific exploration in this area. 【Methods】 High-quality literature published both domestically and internationally between 2012 and 2022 was retrieved through Web of Science (WOS) and China National Knowledge Infrastructure (CNKI) database. Excel and CiteSpace software were applied to visualize the research hotspots and frontier trends. 【Results】 A total of 1 816 English articles and 110 Chinese articles were included in the analysis. The cooperation network density of research institutions and authors was found to be low. Excluding the search terms, the top three English keywords were vitamin A (0.74), intervention (0.67), obesity prevention (0.55); the top three Chinese keywords were "anemia" (0.41), "obesity" (0.38), and "nutritional status" (0.18). In Chinese and English clusters, "anemia" and "physical activity" ranked first, respectively. The latest burst words identified were "dietary pattern" and "diet quality". 【Conclusions】 The number of English literature published in the field of preschool children′s nutrition is increasing, but it has shown a downward trend in the past three years in China. There are few studies in this field in China. The research hotspots primarily focus on the nutritional status of preschool children, with less attention paid to intervention research and methodological exploration. Further research in the field of preschool children′s nutrition in China may need to focus on the external determinants of preschool children′s nutrition, such as parental education, diet and food supply.

【Objective】 To investigate the distribution of body mass index(BMI) among preschool children in Jingzhou City and its correlation with family conditions and feeding practices, so as to provide scientific basis for the health management of overweight and obesity in children. 【Methods】 In August 2022, a cross-sectional study was conducted in Jingzhou City using stratified cluster random sampling. Data on the height, weight, family conditions and feeding practices of children aged 3 - 6 years attending kindergartens were collected. Then BMI was calculated, and multivariate linear regression analysis was performed for data analysis. 【Results】 A total of 14 237 preschool children were surveyed. The overall average BMI was (16.40±3.40) kg/m2. Among them, the porpotion of children whose BMI were in lower, lower-middle, middle, upper-middle and upper range was 0.05%, 1.95%, 86.49%, 4.83% and 6.67%, respectively. Multivariate linear regression analysis revealed that factors such as cesarean birth(β=0.17), paternal smoking(β=0.13), maternal smoking(β=0.39), being female(β=-0.22), total pre-tax family income(β=-0.13), private kindergartens (β=0.22) and a diet pattern primarily consisting of fried chicken, burgers, fries, carbonated drinks, and fruit juices (β=0.46) were linearly correlated with children′s BMI(P<0.05). 【Conclusions】 Overweight and obesity are prevalent among preschool children in Jingzhou City, with a higher proportion of BMI in the upper-middle and upper ranges. Parents and society should collaborate and take appropriate measures to ensure the healthy growth of children.

Association between screen time and psychological behaviors of preschool children in Lanzhou City / 中国儿童保健杂志

Analysis of recessive infection of hand, foot and mouth disease and associated risk factors among healthy children and guardians in Qingdao / 中国学校卫生

Objective@#To investigate the recessive infection rate of healthy children and guardians in different epidemic periods of hand, foot and mouth disease (HFMD) in Qingdao, analyze the risk factors affecting recessive infection, so as to provide the basis for HFMD prevention and control.@*Methods@#In the nonepidemic period of 2022, the random cluster sampling method was used to selected 546 children and guardians from 4 childcare institutions in Laoshan District and Pingdu City. In the epidemic period of 2023, 690 children and guardians were selected from 6 childcare institutions in Shibei District, Laoshan District and Pingdu District. A questionnair survey was conducted in the epidemic period. Logistic regression analysis was used to analyze the factors affecting the recessive infection. Dominance analysis was used to explore the relative importance of the risk factors affecting recessive infection.@*Results@#The results showed that the recessive infection rates of healthy children and guardians in the epidemic period were 18.84% and 13.62%, respectively; the recessive infection rates were 9.09% and 4.44% in the nonepidemic period, respectively. The results of multivariate Logistic analysis showed that rural areas (OR=4.71, 95%CI=2.57-8.61) and recessive infection of guardians (OR=18.62, 95%CI=7.45-46.56) were positively correlated with recessive infection of HFMD in healthy children (P<0.05). Washing hands (OR=0.09, 95%CI=0.04-0.20), using towels alone (OR=0.17, 95%CI=0.07-0.40), and EV71 vaccination (OR=0.42, 95%CI=0.20-0.87) were negatively correlated with recessive infection of HFMD in healthy children (P<0.05). Public toilets (OR=3.02, 95%CI=1.50-6.09) and drying bedding once per quarter (OR=3.89, 95%CI=1.75-8.68) were positively correlated with recessive infection of HFMD in healthy guardians. Housing with good lighting (OR=0.31, 95%CI=0.12-0.79), and tableware disinfection (OR=0.31, 95%CI=0.15-0.65) were negatively correlated with recessive infection of HFMD in healthy guardians (P<0.05). The results showed that recessive infection of guardians was relatively the most important for healthy children (41.51%), and tableware disinfection was relatively the most important for recessive infection of guardians (28.87%).@*Conclusions@#The recessive infections of HFMD are common among healthy populations in Qingdao, and the recessive infection rate among children during the epidemic period is relatively higher. Guardians play an important role in the recessive infection of healthy children. Therefore, healthy education should be strengthened for key populations, especially to enhance parents awareness of prevention and control to reduce the occurrence of recessive infections of hand, foot and mouth disease in children and guardians.
