The association of cesarean section with overweight and neurodevelopment of Chinese children aged 1-5 months.

ObjectiveThe purpose of this survey was to explore the association of delivery mode with overweight and neurodevelopment of Chinese infants aged 1–5 months.Materials and methodsThis study was based on a cross-sectional survey. Data for this study were obtained from the Children’s Nutrition and Health System Survey in China which was conducted from 2019 to 2020. Characteristics of parents and children and the delivery mode were obtained using interview-administered questionnaires. Body mass index-for age z-score (BMI z) was calculated using World Health Organization (WHO) child growth standards. Children’s neurodevelopment was assessed by a trained child health care physician using the Child Psychological Development Scale. The association of delivery mode with infant overweight was analyzed using a multivariable logistic regression model. We conducted a multivariable linear regression model to explore the relationship between delivery modes with neurodevelopment.ResultsIn total, the present analysis included 1,347 children aged 1–5 months, 35.61% were born via cesarean section, of which 15.21% were overweight. After adjustment for infant characteristics and parental factors, the cesarean section was significantly related with the likehood of being overweight [OR = 1.95; 95% confidence interval (CI): 1.27 to 2.98]. Children born via cesarean section had a 3.41-point decrease in gross motor development (β = −3.41; 95% CI: −5.77 to −1.05), a 3.65-point decrease in fine motor development (β = −3.65; 95% CI: −6.03 to −1.28), and a 2.96-point in language development (β = −2.96; 95% CI: −5.20 to −0.73), a 1.65-point in total development (β = −1.65; 95% CI: −3.17 to −0.14) compared with those who were vaginal birth.ConclusionIn our study population, cesarean section was associated with overweight and neurodevelopment outcomes. The cesarean section might increase the likehood of infant overweight, and might decrease the developmental scores of gross motor, fine motor and language. Further studies should be conducted to verify the associations and explore the possible mechanisms.

Prevalence and associated factors for stunting, underweight and wasting among children under 6 years of age in rural Hunan Province, China: a community-based cross-sectional study

BackgroundThe existing epidemiological data cannot represent the situation of undernutrition among Chinese children, particularly those in rural China. Hence, in this community-based cross-sectional study, the prevalence and associated factors of stunting, underweight and wasting among children (age < 6 years) from rural Hunan Province were analyzed.MethodsTotally 5529 children aged 0 to 71 months and their caregivers were randomly chosen by multistage stratified cluster sampling from 72 villages from rural Hunan, which were distributed in 24 towns of 12 counties. Data about the children and their mothers, caregivers and family conditions was acquired using unified questionnaire, and the length/height and weight of each child were measured using unified instruments. The prevalence of undernutrition among children was evaluated using the length/height for age, weight for age, weight for length/height, and body mass index for age z scores, which were computed according to the 2006 and 2007 WHO Child Growth Standards.ResultsThe prevalence of stunting, underweight, and wasting among the 5529 children were 4.4% (241), 3.9% (217), and 4.0% (221), respectively. The significant associated factors on higher risks of undernutrition in the children were low birth weight, maternal gestational weight gain <10 kg (stunting); low birth weight, maternal gestational weight gain <10 kg, ethnicity of caregivers being minority, large family size (underweight); low birth weight, ethnicity of caregivers being minority, large family size (wasting). High education level of caregivers and high family food expenditure were common protective factors for all three types of undernutrition, except that high family food expenditure was not protective against wasting.ConclusionsThe prevalence of stunting, underweight and wasting is low among rural children under age of 6 years in Hunan. As for the measures, the gestational care and reasonable diet of mothers should be strengthened, and nutritional deficiency during pregnancy be avoided, which will prevent low birth weight. The local economic development and the education level of caregivers need to be further improved, especially for minorities.

Effect of Physical Activity on Adolescent Obesity Status over Time: A Latent Growth Modeling Approach.

This study aims to examine the longitudinal influence of physical activity (PA) on obesity among normal-weight adolescents in South Korea. A total of 1347 data samples from the Korean Children and Youth Panel Survey from 2011 to 2014 were used. Latent growth modeling was applied. PA was assessed by the hours spent on PA during physical education (PE) classes in the last week. Body mass index for age was considered to determine obesity status. PA during PE positively predicted the intercept of obesity status, but it was not associated with the slope of obesity status. Although a longitudinal effect of PA was not identified, PA could influence the initial status of obesity. Because obesity in early years could steadily influence future obesity status, early detection and intervention for adolescent obesity are necessary. Moreover, more studies examining the effect of PA during PE on obesity status among adolescents should be conducted to identify the association between PA during PE and obesity status over time.

Infant processed food consumption and their interaction to breastfeeding and growth in children up to six months old

BackgroundEvidences suggest that early processed food (PF) consumption may cause harm to infant health. During the first 6 months of life, it is not known whether the timing and quantity of this food group can impact breastfeeding and growth. The aim of the study was to analyze the associations between time of introduction and quantity of infant PF consumption with duration of breastfeeding and infant growth at 6 months of age.MethodsData were longitudinally collected in six interviews, from birth to 6 months, in a sample of Brazilian newborns with adverse intrauterine environments. PF consumption was calculated by gravity score of processed foods (GSPF) in relation to feeding supply quality and time. For the analysis, the scores were divided into tertiles, making scores severities: Null, Mild, Moderate, and Severe. The interaction between GSPF and breastfeeding (exclusive and non-exclusive) and growth parameters (analyzed in Z-scores, by weight for height, weight for age, and body mass index for age) was tested.ResultsA total of 236 infants were included in the study. Greater GSPF were associated with better rates of breastfeeding practices and higher growth indicators scores in the sixth month of infants. These findings were confirmed after adjustment for family income, maternal age, pre-gestational body mass index, and growth z scores at birth.ConclusionThe harms of eating PF in relation to breastfeeding and infant growth are more evident the greater and earlier they are consumed. Future studies should explore interventions to reduce and delay the consumption of these foods to prevent adverse health outcomes in later life.

Evaluation of blood and tooth element status in asthma cases: a preliminary case\u2013control study

BackgroundAsthma is a common respiratory disorder; some data were present on the correlation between increased levels of some elements and the risk of asthma development. It was aimed to evaluate the levels of 13 selected blood and tooth elements (magnesium, phosphorus, calcium, chromium, manganese, iron, copper, zinc, strontium, molybdenum, cadmium, lead, mercury) in a well-controlled asthma group and the control group.MethodsDuring the study period, 17 asthma patients and 26 age and gender-matched healthy children donated shed deciduous teeth having neither decay nor filling and enrolled for the study. The element levels in blood and teeth matrixes were analyzed with inductively coupled plasma mass spectrometry. Differences in blood and tooth elements in groups were evaluated with generalized linear models after adjusting confounding factors.ResultsAfter adjusting the child’s “z scores of body mass index for age”, history of iron deficiency anemia, and status of parental smoking, the generalized linear model revealed significantly lower tooth magnesium levels, lower blood zinc levels, and lower blood zinc/copper ratio in the asthma group than the control group (p = 0.042, p = 0.034, p = 0.002, respectively). Other studied elements for tooth and blood matrixes were similar in groups.ConclusionOur study revealed some differences in tooth and blood element levels in the asthma group. Further studies on zinc and magnesium levels of severe asthma cases are necessary for the interpretation of the results.

The Impact of Obesity on Periodontal Health Status in Adolescent Iraqi Students

Objetive: The aim of this study was to estimate the effect and association of obesity on the periodontal health status of middle school students. Materials and Methods: This study included 180 secondary school students aged 12- 15 years from Baghdad City in the survey. BMIfor-age (body mass index for age) was utilized to detect overweight and obesity. Furthermore, periodontal screening records (PSR) index was performed to evaluate the oral hygiene and periodontal condition of the subjects. Chisquare tests and two-way ANOVA were used for statistical analyses. Results: A highly significant association of BMI-for-age with periodontal health (codes 0, 1, 2, and 3) was observed. The association of gender and periodontal health was highly significant in code 3, significant in codes 0 and 1, and it was not significant in code 2. Additionally, the ANOVA test revealed that the effects of gender and BMI-for-age on periodontal health were significant. In contrast, the effect of the interaction between gender and BMI-for-age on periodontal health was not it was not significant. Conclusions: In adolescents, bad oral hygiene was correlated with extra body fat indicators. Therefore, oral health preventive schedules should take into consideration the relationship between periodontal condition and overweight/obesity in teenagers.

Toxic stress, health and nutrition among Brazilian children in shelters

BackgroundLiving in a shelter is an adverse experience that generates toxic stress. This situation can cause the dysregulation of the hypothalamic-pituitary-adrenal axis and exert a negative impact on health.The aim of the present study was to determine the association between toxic stress and social, clinical and nutritional characteristics in children at welfare institutions in a city of northeastern of Brazil.MethodsAn analytical, cross-sectional study was conducted with male and female children up to 60 months of age who live in shelters. Hair cortisol was used for the assessment of stress (immunoassay). The anthropometric data collected were height for age, body mass index for age, arm circumference for age, and head circumference for age (expressed in z-scores). We also evaluated food intake using markers proposed by the Brazilian Dietary and Nutritional Vigilance Surveillance System as well as the occurrence of dental caries and anemia.ResultsSixty-three children one to 60 months of age participated in the present study. Asthma was the most frequent disease (11.1%). The prevalence of short stature, anemia and dental caries in the sample was 22.2, 22.2 and 9.4%, respectively. Cortisol levels ranged from 0.93 pg/mg to 391.29 pg/mg (median: 6.17 pg/mg). Higher cortisol levels were found in children with illnesses (p = 0.012) and those who had been hospitalized after being admitted to the institutions (p = 0.001).ConclusionsThe majority of children had unhealthy eating behavior. The cortisol concentrations found in the present study were suggestive of dysregulation of the hypothalamic-pituitary-adrenal axis. Hypercortisolism was associated with illness and hospitalization.

The effects of nutritional support baskets on growth parameters of under five years old children with malnutrition and low socio-economic status.

Although malnutrition is globally widespread among children, there is no consensus on the most effective intervention for improving a child's growth. The present study is designed to investigate the effects of nutritional support basketson growth indices of malnourished children. This is a field trial conducted on 3667 malnourished children (0-60 months) for 9months, between 2017 and 2018, in Fars province of Iran. Weight-for-age, height-for-age, weight-for-height and body mass index-for age indices were assessed before and after the intervention with nutritional support baskets, which contains 600 kcal/day. The baseline prevalence of moderate/severeunderweight, stunting and wasting were 31.5%, 33.3% and 28.9%, respectively. After the intervention, the prevalence non-significantly reduced to 25.5%, 31.7% and 20.35%, respectively (p > 0.05). The intervention is associated with a non-significant reduction in the prevalence of underweight and wasting in 0-23 months children, and a non-significant reduction in the prevalence of underweight, stunting and wasting in 24-60 months children. Furthermore, the intervention is associated with a non-significant reduction in the prevalence of underweight, stunting and wasting in girls, and a non-significant reduction in the prevalence of underweight and wasting in boys. Nutrition support was effective in improving malnutrition indices of children; however, the results were non-significant. Further studies with longer period and control group areneeded to support the effectiveness of nutrition support in children.

The association between urinary BPA levels and medical equipment among pediatric intensive care patients

We aim to evaluate urinary total BPA (tBPA) levels and association with medical devices used on patients in pediatric intensive care units. This cross-sectional descriptive study included 117 critically ill children. Urinary tBPA levels were determined using high-performance liquid chromatography. General estimating equations with repeated measures analyzed the effect of interventions and devices on urinary BPA levels. A total of 292 urine samples taken from 117 child intensive care patients were studied. When age, sex, and body mass index-for age z-scores were controlled, cases having endotracheal intubation showed higher urinary tBPA levels (p = 0.003) and hemodialyzed patients had considerably higher urinary tBPA levels (p = 0.004). When confounding factors were controlled, cases using both multiple iv treatment and more than four medical devices showed higher urinary tBPA levels than their counterparts (p = 0.007 and p = 0.028, respectively). The use of certain medical devices and interventions could increase BPA exposure in pediatric intensive care patients.

Examination of Adolescents' Attention, Appetite and Nutritional Status

Aim: The aim of this study was to examine adolescent’s attention levels, in which mood they tend to eat, eating habits and the relationship among them.&#x0D; Methods: This study was conducted in February 2020 on 142 students in total, 69 (48.6%) of them girls and 73 (51.6%) of them boys who are studying at Süleymaniye Educational Institutions Bağlıca Secondary School in Turkey. Data were collected by a questionnaire with 38 questions and a 24-h dietary recall to determine the personal characteristics and the eating habits of adolescents; the D2 Attention Test was used to determine attention levels and the Emotional Appetite Questionnaire was used to identify appetite.&#x0D; Results: 38.7% of the participants in the study were overweight and 23.2% were obesity. The D2 Attention test found that mean TN (total number of items processed) and CP (concentration performance) scores were positively correlated with age and negatively with Body Mass Index for age. A significant and negative correlation was found between glucose intake and the TN (total number of items processed) scores.&#x0D; Conclusions: A high risk of obesity was founded in these secondary school students. At the same time, it is thought that there may be a relationship between individuals' macro and micronutrient consumption and their emotional eating tendency and attention levels. For this reason, it is important to detect and improve dietary habits of adolescence, which is a critical process for future generations.

Prevalence of Obesity/Abdominal Obesity and Related Factors in Pediatric ALL Survivors

Objective Obesity has been increasingly recognized in pediatric acute lymphoblastic leukemia (ALL) survivors. The aim of the current study was to determine the prevelance and related factors of obesity/abdominal obesity and evaluate the association between nutrition and overweight/obesity after cancer treatment in pediatric ALL survivors. Method An observational retrospective cohort study was performed among 67 volunteers (aged 5–15). Participants completed 3 consecutive days (2 weekdays and 1 weekend day) recording food consumption and physical activity simultaneously. Weight, height, and waist circumference measurements were performed in remission period, and retrospective data were obtained from patient records. We examined data at three periods: diagnosis, end of treatment, and remission. Subjects were classified into four groups according to body mass index for age z score (BAZ): underweight, normal weight, overweight, and obese. Abdominal obesity was defined waist-to-height ratio ≥ 0.5. Results Prevalence of overweight, obesity, and abdominal obesity were 25.3%, 23.9%, 38.8%, respectively in remission. BAZ at diagnosis and at treatment completion, dietary energy intake, and physical activity were associated with an increased risk of being overweight/obese in remission (p < .05). Gender, age at diagnosis, cranial radiotherapy, and treatment risk category were not significant (p > .05). Conclusions As in obesity, abdominal obesity was found an important problem in pediatric ALL survivors. Therefore, nutritional targets are needed to prevent obesity. Survivors should be closely monitored in terms of nutritional status during and after treatment and informed about and supported for healthy lifestyle (balanced and adequate nutrition, increase in physical activity).

O estado nutricional de crianças de 5 e 6 anos de idade em duas escolas públicas de Criciúma/SC

O estado nutricional de uma criança desempenha papel fundamental no crescimento progressivo e auxilia que desenvolva habilidades sociais e psicomotoras. Este estudo teve como objetivo caracterizar o estado nutricional de escolares participantes de um projeto extensionista, de uma universidade comunitária. A amostra incluiu 80 crianças, entre 5 e 6 anos de idade e matriculadas no primeiro ano do ensino fundamental em escolas públicas. Para avaliação do estado nutricional, foram coletados dados de peso e estatura, dobra cutânea tricipital e subescapular, além da idade e sexo. Para classificação do estado nutricional foi utilizado o índice de massa corporal para idade (IMC/I). Verificou-se que 17,6% da amostra apresentou índices de sobrepeso, obesidade e obesidade grave. O estudo apontou maior frequência de obesidade em escolares do sexo feminino (p = 0,034). Há prevalência de padrões eutróficos nos escolares avaliados, porém identificou nas crianças avaliadas o padrão de sobrepeso em 11,3%, obesidade em 5% e obesidade grave em 1,3%. Diante do cenário encontrado, a implantação de programas educativos com o intuito de conscientizar a comunidade escolar sobre o problema da obesidade é de suma importância, para criar soluções adequadas às diferentes populações, em prol da erradicação da obesidade infantil.

Association between Food Habits and Nutritional Status of Secondary School Students in Kuala Lumpur, Malaysia: Baseline Findings from Nuteen Project.

Dietary habits and choice of food influences nutritional status of adolescence. Malnutrition have been associated with adolescents' dietary habits that may predispose to chronic disease during their adulthood. The aim of this study is to determine the association between food habit and nutritional status of adolescents. In the baseline study, a total of 924 students from 10 secondary schools were randomly selected from a total of 62 secondary schools in Kuala Lumpur. The students were assessed on various dietary components including food habits using a structured questionnaire as well as for anthropometry measurements. All data were analyzed using SPSS 23. The prevalence of obesity was significantly higher among males compared to females (16.4% vs. 8.4%, X2=25.42, p<0.001). Food habit exhibits an inversed association with z-score of body mass index for age (β=-0.107, 95% CI=-0.053, -0.013), especially via food habits such as often eat dinner (r=-0.102, p=0.002), often have breakfast before school (r=-0.100, p=0.002), often eat cake or dessert at meal (r=-0.110, p=0.001), often drink eight glasses of water (r=0.132, p<0.001), often eat food from school canteen (r=-0.071, p=0.031) and often bring own snack from home (r=-0.112, p=0.001). This study suggested that the type of food and timing of meal should be considered to prevent obesity among adolescents.

Prevalence and factors associated with excess weight in adolescents in a low-income neighborhood - Northeast, Brazil

Abstract Objectives: to study the prevalence of excess weight and associated factors among adolescents from a low-income neighborhood located in the city of Recife, Pernambuco. Methods: cross-sectional study, in which behavioral, socioeconomic and demographic information was collected from June to December 2014. Excess weight was calculated based on body mass index for age and the cut-off points, by the World Health Organization (2007). To analyze associations between predictor variables and the outcome, multivariate data analysis was performed following the Poisson Regression (Prevalence Ratio - PR) with their respective 95% confidence intervals (95%CI). Results: twenty-five adolescents participated in the study, with a prevalence of 36.4% of excess weight: 20.4% overweight (95%CI=15.1-25.7) and 16.0% obesity (95%CI= 11.2-20.8), predominantly in female gender (42.5%; p=0.031). The outcome was associated with internet access (PR=1.20; 95%CI=1.01-1.43), the number of people in the family (PR= 1.12; 95%CI=1.01-1.28) and screen time (PR=1.13; 95%CI=1.01-1.27), but only in male gender. Conclusions: the prevalence found was higher than that of other national researches, especially for the female gender. In the male gender, not having internet access, a lesser number of family members and a longer screen time proved to be factors associated with being excess weight.

Estado Nutricional de Pacientes Pediátricos Recém-Diagnosticados com Leucemia Linfoblástica Aguda em um Instituto de Referência em Oncologia do Rio de Janeiro

Introdução: A leucemia linfoblástica aguda (LLA ) constitui a neoplasia mais comum em pediatria e a avaliação nutricional é um instrumento essencial para conhecer as condições de saúde dos pacientes. O presente estudo teve como objetivo avaliar e descrever o estado nutricional de pacientes pediátricos recém-diagnosticados com LLA e verificar a relação do índice de massa corporal para idade (IMC/I) com as demais medidas antropométricas. Método: Estudo observacional, transversal, realizado com pacientes de 1 a 18 anos, recém-diagnosticados com LLA , no período de janeiro/2004 a dezembro/2009. Os dados coletados foram idade, peso corporal, estatura, prega cutânea tricipital (PCT), circunferência do braço (CB) e circunferência muscular do braço (CMB). O IMC foi calculado e a classificação IMC/I utilizada na análise. O teste Qui-quadrado de Pearson e Exato de Fisher foram utilizados para analisar a associação entre os parâmetros antropométricos. Resultados: Foram incluídos no estudo 54 pacientes. A classificação do “estado nutricional adequado” foi a mais frequente em todos os parâmetros antropométricos. Em adição, observou-se que a associação do estado nutricional pela CMB com o IMC/I (p=0,001) demonstra que este último pode ser adequado para classificação dos pacientes pediátricos com LLA ao diagnóstico. E a concordância da CB com a CMB (p=0,01) de 43% (p=0,001) também ratifica a utilização da CB frente à CMB, por ser uma medida mais simples. Conclusão: Na população estudada, o estado nutricional encontrava-se preservado. Assim como a associação da CMB com o IMC/I, a CB demonstrou ser um parâmetro sensível para classificar eutrofia.

Tetralogy of Fallot Repair in Developing Countries: International Quality Improvement Collaborative

Isolated reports from low- and middle-income countries (LMICs) for surgical results in tetralogy of Fallot (TOF) are available. The International Quality Improvement Collaborative for Congenital Heart Disease (IQIC) seeks to improve surgical results promoting reductions in infection and mortality in LMICs. All cases of TOF in the IQIC database performed between 2010 and 2014 at 32 centers in 20 LMICs were included. Excluded from the analysis were TOF with any associated lesions. A logistic regression analysis was performed to identify risk factors for in-hospital mortality after surgery for TOF. A total of 2,164 patients were identified. There were 1,839 initial primary repairs, 200 with initial systemic-to-pulmonary artery shunt, and 125 underwent secondary repair after initial palliation. Overall mortality was 3.6% (78 of 2,164), initial primary repair was 3.3% (60 of 1,839), initial systemic-to-pulmonary artery shunt was 8.0% (16 of 200), and secondary repair was 1.6% (2 of 125; p= 0.003). Major infections occurred in 5.9% (128 of 2,164) of the entire cohort. Risk factors for death after the initial primary repair were oxygen saturation less than 90% and weight/body mass index for age below the fifth percentile (p < 0.001). The initial primary repair occurredafter age 1 year in 54% (991 of 1,839). Older age at initial primary repair was not a risk factor for death (p= 0.21). TOF patients are often operated on after age 1 year in LMICs. Unlike in developed countries, older age is not a risk factor for death. Nutritional and hypoxemic status were associated with higher mortality and infection. This information fills a critical knowledge gap for surgery in LMIC.

Maternal smoking during pregnancy and early development of overweight and growth deficit in children: an analysis of survival

Abstract Objectives: to evaluate the association between smoking during pregnancy and nutritional status. Methods: cohort study with a sample of 460 children in the baseline. The children were assessed four times, being measured for weight and length to be converted in indexes length forage (L/A) and body mass index forage (BMI/A) in Z-score. The time until occurrence of growth deficit and overweight was calculated in days and compared to maternal smoking during pregnancy. To assess the association between smoking during pregnancy and the outcomes, a Hazard Ratio by Cox regression was obtained, adjusting by confounding variables selected from Directed Acyclic Graphs (DAG). Results: the time until occurrence of growth deficit and overweight was lower in children whose mothers smoked during pregnancy. Smoking during pregnancy was a risk factor for length deficit (HR = 2.84; CI95% = 1.42 to 5.70) and for overweight (HR = 1.96; CI95% = 1, 09 to 3.53), even after the adjustment. Conclusions: maternal smoking was a changeable factor associated with anthropometric outcomes, which demonstrates the need for actions to combat smoking during pregnancy in order to prevent early nutritional deviations.

Effect of synbiotic supplementation in children and adolescents with cystic fibrosis: a randomized controlled clinical trial.

Cystic fibrosis (CF) is characterized by excessive activation of immune processes. The aim of this study was to evaluate the effect of synbiotic supplementation on the inflammatory response in children/adolescents with CF. A randomized, placebo-controlled, double-blind, clinical-trial was conducted with control group (CG, n = 17), placebo-CF-group (PCFG, n = 19), synbiotic CF-group (SCFG, n = 22), PCFG negative (n = 8) and positive (n = 11) bacteriology, and SCFG negative (n = 12) and positive (n = 10) bacteriology. Markers of lung function (FEV1), nutritional status [body mass index-for age (BMI/A), height-for-age (H/A), weight-for-age (W/A), upper-arm fat area (UFA), upper-arm muscle area (UMA), body fat (%BF)], and inflammation [interleukin (IL)-12, tumor necrosis factor-alpha (TNF-α), IL-10, IL-6, IL-1β, IL-8, myeloperoxidase (MPO), nitric oxide metabolites (NOx)] were evaluated before and after 90-day of supplementation with a synbiotic. No significance difference was found between the baseline and end evaluations of FEV1 and nutricional status markers. A significant interaction (time vs. group) was found for IL-12 (p = 0.010) and myeloperoxidase (p = 0.036) between PCFG and SCFG, however, the difference was not maintained after assessing the groups individually. NOx diminished significantly after supplementation in the SCFG (p = 0.030). In the SCFG with positive bacteriology, reductions were found in IL-6 (p = 0.033) and IL-8 (p = 0.009) after supplementation. Synbiotic supplementation shown promise at diminishing the pro-inflammatory markers IL-6, IL-8 in the SCFG with positive bacteriology and NOx in the SCFG in children/adolescents with CF.

Measuring Factors Influencing Progression across the Stages of Readiness to Lose Weight among Overweight and Obese Adolescents

Epidemic incidence of obesity has become one of the public health priorities in disease control prevention. The study aims to determine the prevalence of readiness stages to lose weight among the overweight and obese adolescents and its influencing factors. A cross-sectional study was conducted on 631 adolescents of body mass index for age with z-score > 1 SD based on World Health Organization growth reference chart. The stages of readiness to lose weight were assessed using Trans-Theoretical Model. Intrinsic and extrinsic factors were collected using self-administered questionnaire. Majority of the respondents were in the action stage (40.3%) followed by contemplation (26.5%), preparation (15.5%), maintenance (11.4%) and pre-contemplation (6.3%). Ordinal regression analysis identified significant factors influencing progression across the stages of readiness to lose weight: no junk foods sold in school canteens (p = 0.005), TV viewing time ≤2 hours (p = 0.001), high physical activity means score (p < 0.001) and family encouragement on healthy eating (p = 0.010). Majority of adolescents who were overweight and obese were at the action stage of weight reduction. Focusing on extrinsic factors help to improve the effectiveness of weight management intervention.

Maternal perception of their child's nutritional status at less than three years old.

Assessing maternal perception of their children's nutritional status and identifying associated factors. A cross-sectional study conducted in a small municipality with 342 children less than 3 years of age treated in Basic Health Units of São Paulo. Nutritional status was classified in percentiles of body mass index for age and maternal perception was assessed using the scale of verbal descriptors (very thin, thin, healthy weight, fat, very fat). Logistic regression was used to identify the associatedfactors. 44.7% of maternal perception was found to beinadequate. Mothers of overweight (OR = 11.8, 95% CI: 6.4-21.7) and underweight (OR = 5.5; 95% CI: 1.9-16.2) children had a higher chance of having inadequate perception, similar to mothers of children over 24 months of age (OR = 2.9; 95% CI: 1.4-6.0). For effective child care in primary care, healthcare professionals should consider maternal perception and helpmothers to identify the nutritional status of children in childcare consultations and growth monitoring. Avaliar a percepção materna do estado nutricional do filho e identificar os fatores associados. Estudo transversal realizado em município de pequeno porte com 342 crianças menores de 3anos atendidas em Unidades Básicas de Saúde do Estado de São Paulo. O estado nutricional foi classificado em percentis do Índice de Massa Corporalpara Idade e a percepção materna foi avaliada com escala de descritores verbais (muito magro, magro, peso adequado, gordo, muito gordo). Utilizou-se de regressão logística para identificar os fatores associados. Constatou-se 44,7% de percepção materna inadequada. Mães de crianças com excesso de peso (OR=11,8; IC95%:6,4-21,7) e com baixo peso (OR=5,5; IC95%:1,9-16,2) apresentaram mais chance de percepção inadequada, da mesma forma que mães de crianças com mais de 24 meses de idade (OR=2,9; IC95%:1,4-6,0). Para uma efetiva assistência à criança na atenção básica, profissionais de saúde devem considerar a percepção materna e auxiliar as mães na identificação do estado nutricional do filho nas consultas de puericultura e acompanhamento do crescimento.
