RESUMO

INTRODUCTION: The first 1000 days of life could contribute to individual susceptibility to the later development of chronic non-communicable diseases. Nutrition in early life appears to be an important determinant factor for a sustainable child's health. In this study, we propose to investigate the impact of exclusive breast feeding on gut health in children. METHODS AND ANALYSIS: A prospective cohort of newborns (n=350) will be recruited at birth and followed up to 4 years of age. The main objective is to evaluate the link between exclusive breast feeding for at least 3 months and the gut health of the child at 4 years. The primary endpoint of assessment of gut health will be based on the non-invasive measurement of faecal secretory IgA (sIgA) as a sensitive biomarker of the intestinal ecosystem. The presence of gastrointestinal disorders will be defined according to the clinical criteria of Rome IV. Information on parent's nutritional habits and life style, breastfeeding duration and child's complementary feeding will be collected along the follow-up. Cord blood cells and plasma at birth will be purified for further analysis. The meconium and stools collected at birth, 6 months, 2 years and 4 years of age will allow sIgA analysis. ETHICS AND DISSEMINATION: This clinical study has obtained the approval from the national ethical committee. We plan to publish the results of the study in peer-review journals and by means of national and international conference. TRIAL REGISTRATION NUMBER: NCT04195425.

RESUMO

AIM: The present study examined the predictive factors for the survival prognosis in older adults. METHODS: The subjects were 431 patients (75-99 years old) who visited our hospital between April 2016 and March 2019. Multivariate analyses were conducted to clarify the survival prognosis (P <0.05). RESULTS: In a Cox regression analysis, the significant factors for the survival were the age (hazard ratio [HR] 1.050, 95% confidence interval [CI] 1.014-1.087), Charlson comorbidity index (CCI) (low vs. medium: HR 0.106, 95% CI 0.032-0.353; low vs. high: HR 0.244, 95% CI 0.150-0.398; low vs. very high: HR 0.514, 95% CI 0.326-0.809), pre-hospitalized gait (HR 1.861, 95% CI 1.158-2.988), sitting at discharge (HR 0.429, 95% CI 0.277-0.663), subcutaneous adipose tissue index (SATI) (HR 0.988, 95% CI 0.979-0.997) and modified controlling nutritional status (m-CONUT) (normal vs. light: HR 0.114, 95% CI 0.042-0.311; normal vs. moderate: HR 0.235, 95% CI 0.110-0.502; normal vs. severe: HR 0.351, 95% CI 0.166-0.741). In decision tree analyses, the significant factors for the 1-year survival were a CCI of low >medium >high-very high, body mass index of >20.7 kg/m2, m-CONUT of normal-light >moderate-severe and sitting at discharge, and those for the 2-year survival were sitting at discharge, a SATI of >43.9 cm2m-2, a CCI of low-medium >high-very high, male moderate-severe. CONCLUSIONS: High SATI and body mass index values appeared to be associated with better survival outcomes.

RESUMO

Background: Adolescence is a highly vulnerable period of human life characterized by substantial physiological and cognitive changes for which adequate nutrition is crucial. To date, evidence on determinants, prevalence, and trends of undernutrition and anemia for the entire West and Central African region is missing. This paper provides evidence on trends and levels of adolescent anemia and undernutrition in West and Central Africa. Methods: We pooled all Demographic and Health Surveys (DHS) for West and Central African countries that were conducted between 1986 and 2017 to analyze levels and trends of adolescent anemia and undernutrition. We investigated the association of adolescent undernutrition and anemia within this region with World Bank income level classification of the country. Results: Our findings suggest that the regional prevalence of adolescent anemia and undernutrition remained high at 45% and 19% respectively over the last 20 years. Anemia increased in about one third of countries and undernutrition in about two thirds over the studied period. On the aggregated level, these trends are largely masked and both levels remained stable in the entire region between the years 1998 and 2017. The results of the multivariable regression analysis indicate an association of adolescence with undernutrition and anemia, which was independent of socio-economic factors such as income, education, and place of residence. Conclusion: We conclude that levels of adolescent undernutrition and anemia remain high with little progress over the last 20 years and that adolescence is a significant correlate of both anemia and undernutrition. Given the recognition of the international community that adolescent nutrition is an important public health concern in resource-poor settings, there is an urgent need to improve data availability, quality, and use for decision-making and to design successful high-impact interventions to combat adolescent malnutrition in low- and middle-income countries.

RESUMO

BACKGROUND: The controlling nutritional status (CONUT) score has been widely used to evaluate the nutritional and immunological status. Clinical value of postoperative CONUT (PoCONUT) score in hepatocellular carcinoma (HCC) remains unknown. This study assessed whether PoCONUT score could serve as a useful predictor of survival for patients with small HCC. METHODS: 547 consecutive patients with small HCC who underwent liver resection between February 2007 and December 2015 were included in this retrospective case-control study. Patients were categorized into two groups: low PoCONUT group (PoCONUT score ≤ 2, n = 382) and high PoCONUT group (PoCONUT score ≥ 3, n = 165). Propensity score matching (PSM) analysis was applied to balance the bias in baseline characteristics. A cumulative survival curve was established by the Kaplan-Meier method, and differences in OS and RFS among CONUT score groups were determined by the log rank test. Cox proportional hazard regression analysis was used to evaluate the association of PoCONUT score and overall survival (OS) and recurrence-free survival (RFS), with calculation of hazard ratios (HRs) and 95 % confidence intervals (95 % CIs). RESULTS: Cox proportional hazard regression analysis suggested that the PoCONUT score was an independent risk factor for both OS and RFS in patients with small HCC before and after PSM. CONCLUSIONS: High PoCONUT score helps to predict worse OS and RFS in patients with small HCC who underwent liver resection.

RESUMO

Introduction: different studies have shown a relationship between depression and nutrition, but there seems to be no consistent consensus on this. This study therefore investigated the relationship of nutrition status and depression among workers in tertiary educational institutions in Southwestern Nigeria. Methods: this was a cross-sectional study conducted among 399 members of staff of three tertiary educational institutions in Osun State, Southwestern Nigeria. Depression was assessed using the Patient Health Questionnaire-9 (PHQ-9), while nutritional status was assessed using the body mass index (BMI), waist circumference and waist hip ratio (WHR). The respondents were selected using multi-stage sampling technique, and data were collected using pre-tested structured questionnaires. Analysis was done using IBM SPSS. Results: the mean age of the respondents was 45.8 ± 10.4 years. The prevalence of depression was 23.8%. Concerning the nutritional status of respondents, 2.3% were underweight and 69.7% were overweight/obese. There were statistically significant associations between depression and the nutritional status of the respondents using BMI (p = 0.001), WHR (p = 0.015) and waist circumference (p = 0.036). After controlling for other factors, only the BMI was still significantly associated with depression, such that those underweight were more likely to be depressed (Odds ratio: 7.9; p-value: 0.009). Conclusion: the prevalence of depression among the respondents was relatively high, and this was significantly associated with the BMI, even after controlling for co-founders.

RESUMO

The article presents methodological aspects of anthropometric assessment of nutritional status in children under five years of age and their biological mothers. It discusses the strategies used for training and data collection in the Brazilian National Survey on Child Nutrition (ENANI-2019). ENANI-2019 is a population-based household survey conducted in 123 municipalities in Brazil's 26 states and the Federal District. The anthropometric measurements were body mass and length/stature. The equipment was purchased according to its measurement capacity and precision, portability, and cost-benefit ratio after an extensive market search. The study used internationally established procedures described in manuals, videos, and support material developed for the study by a group of experts. The interviewers were trained to perform the anthropometric measurements and were assessed according to technical measurement error, which was considered adequate (0.30cm) for the children's length/stature measurements. Measurement errors were identified, and the interviewers were retrained when necessary. Of the 14,558 children in the sample, body mass and length/stature measurements were taken in duplicate in 13,835 and 13,693 children, respectively. The standardized methodological aspects will be helpful in future population studies and were essential for obtaining greater reliability in the data for generating current evidence on the anthropometric assessment of the nutritional status of Brazilian children under five years of age, allowing new perspectives for public policy development.

RESUMO

This article aims to present methodological aspects on the collection, analyses, coverage, challenges, and the lessons learned from laboratory assessment of micronutrients on the Brazilian National Survey on Child Nutrition (ENANI-2019). This is a household survey on a probability sample of children under five years of age from 123 Brazilian municipalities in all 26 states and the Federal District. Blood samples were drawn by venipuncture at the homes of children 6 to 59 months of age. This procedure was performed by experienced phlebotomists from the laboratories located in the selected municipalities and scheduled in advance. Blood and serum levels were measured for biomarkers of nutritional status, using the services of a clinical test laboratory with nationwide coverage, for the following micronutrients: iron (hemoglobin and ferritin), zinc, selenium, folic acid, and vitamins A, B1, B6, B12, D, and E. C-reactive protein was analyzed as a marker of inflammation. A barcode identifier was used to track the blood samples and to link the biochemical test results to the other data collected in the survey. A total of 14,558 children were studied. Of the 12,598 eligible children, 8,829 (70.1%) had blood samples drawn. Of the total number of children who had samples drawn, 91.8% (n = 8,025) have results for at least nine of the 12 analyses performed. Coverage of the analysis varied from 95% (for vitamins A and E) to 84.2% (for folic acid). Aliquots of whole blood and serum were stored in a biorepository for future analyses. The results of this pioneering study in the country will back the formulation and, when necessary, the reorientation of public policies in food and nutrition.

RESUMO

INTRODUCTION: Malnutrition and kala-azar (or visceral leishmaniasis) are significant public health problems in different parts of the world. Immunity and susceptibility to infectious and parasitic diseases are directly linked to the host's nutritional state, but little is known about the interaction between nutrition and kala-azar. This study aimed to evaluate nutritional status with kala-azar and correlate these findings with the clinical and laboratory manifestations of the disease, and zinc and retinol levels. METHODS: This was a cross-sectional study of 139 patients with kala-azar. Nutritional status classification was performed according to international recommendations. Parametric or nonparametric tests were applied whenever indicated in a two-sided test with a 5% significance level. RESULTS: Weight loss and malnutrition were more frequent in adults. Body mass index-for-age, fat area of the arm, and upper arm muscle area were significantly associated with probability of death. The presence of human immunodeficiency virus, hepatomegaly, and splenomegaly was correlated with nutritional assessment. Blood leukocyte and lymphocyte, serum creatine, and vitamin A levels were significantly higher in adult men. Vitamin A levels were highly associated with the level of hemoglobin and C-reactive protein (CRP) in multivariate analysis. All patients had reduced plasma zinc levels, but this finding had no association with the outcome variables. CONCLUSIONS: Malnutrition was correlated with severe disease and was more prevalent in older people with kala-azar. Vitamin A deficiency was associated with hemoglobin and CRP. Zinc levels were reduced in patients with kala-azar.

RESUMO

ABSTRACT: Severity of illness, age, malnutrition, and infection are the important factors determining intensive care unit (ICU) survival.The aim of the study is to determine the relations between Geriatric Nutritional Risk Index (GNRI), C-reactive protein/albumin (CAR), and prognosis-mortality of geriatric patients (age of ≥65 years) admitted to intensive care unit.The study with 10/15/2020, 697 approval date, and number retrospectively registered. Between January 1, 2018 and December 31, 2019, 413 geriatric patients admitted to ICU. The patients were divided into three groups according to their age.The age group, gender, Charlson comorbidity index, intensive care scores (Acute Physiology And Chronic Health Evaluation II and Sequential Organ Failure Assessment), the infection markers (white blood cell, procalcitonin, CAR levels), malnutrition tools for each patient (body mass index, Nutrition Risk in Critically ill score, and GNRI scores) were analyzed retrospectively. Also length of stay (LOS) ICU, length of stay hospital, and 30-day mortality were recorded.Geriatric patients number of 403 was included in the study. Forty-nine (12.3%) patients had a history of malignancy, 272 (67.5%) patients had Chronic Obstructive Pulmonary Disease comorbidity. There was no difference in mortality between age groups.In patients with mortality, body mass index, had being Chronic Obstructive Pulmonary Disease history, GNRI, length of stay hospital, and albumin were significantly lower; malignancy comorbidity rate, inotrope use, modified Nutrition Risk in Critically ill score, mechanical ventilation duration, LOS ICU, Sequential Organ Failure Assessment, Acute Physiology And Chronic Health Evaluation II, Charlson comorbidity index, C-reactive protein, procalcitonin, and CAR were significantly higher.Both malnutrition and infection affect mortality in geriatric patients in intensive care. The GNRI is better than CAR at predicting mortality.

RESUMO

BACKGROUND: The focus of care has shifted from institutional care to home care. Family caregivers provide the majority of home care that allows an opportunity for their care recipients to live at home and avoid costly institutional care. The aim of this study is to describe the nutritional status, oral health, and quality of life of family caregivers over the age of 65 and their care recipients, and to evaluate the impact of individually tailored diet and oral health advice to their nutritional status and oral health. METHODS/DESIGN: Altogether, 250 family caregivers aged 65 or over, and their care recipients are studied in this prospective randomized population-based multidisciplinary 6-month intervention study. Participants are randomly allocated to the intervention groups or the control group. Data collection is performed at three time-points: at baseline and 6 months and after a 6-month follow-up at 12 months. Caregivers' and their care recipients' nutritional and oral health status as a primary outcome, and functional ability, cognitive status, quality of life, depression symptoms, sense of coherence, morbidity, and medication of family caregivers as secondary outcomes will be measured using validated self-administered questionnaires and clinical examinations. DISCUSSION: To our knowledge, this is the first experiment to determine whether caregivers and their care recipients benefit from individual nutritional intervention and oral health intervention in terms of nutrition status, oral health status, and quality of life. TRIAL REGISTRATION: ClinicalTrials.gov NCT04003493 . Registered on June 28, 2019.

RESUMO

PURPOSE: To analyze the nutritional status of patients with malignant oral and maxillofacial neoplasms complicated with diabetes mellitus during perioperative period. METHODS: Sixty-four patients with malignant oral and maxillofacial neoplasms complicated with diabetes mellitus were collected. Fasting venous blood of patients was extracted on the morning of the day before surgery and then at the 1st, 3rd and 7th day after surgery, respectively. The hemoglobin (Hb), total protein (TP), pre-albumin (PA), lymphocyte count (L), creatinine (Scr), uric acid (UA), urea nitrogen (BUN), glomerular filtration rate (EGFR_EPI_C), white blood cells (WBC) of the patients were detected. The intake of enteral nutrition on the 7th day after operation was investigated. The correlation between nutritional status and the length of stay was analyzed. SPSS 23.0 software package was used for statistical analysis. RESULTS: Compared with the indicators before surgery, the values of TP, ALB, PA, Hb were decreased significantly after surgery in all groups(P<0.05). The level of TP on postoperative day 7 was significantly higher than that on postoperative day 1 and postoperative day 3(P<0.05). The PA level on the third day after surgery was significantly lower than that on the first day after surgery(P<0.05). The Hb level on the 7th and 3rd day after surgery was significantly lower than that on the 1st day after surgery (P<0.05). The level of L decreased significantly in each group after surgery compared with the level before surgery(P<0.05), and gradually increased in each group after surgery, with significant difference among each two groups (P<0.05). Compared with preoperative value, blood Scr was significantly decreased in all groups after surgery (P<0.05), the UA level after surgery was significantly lower than the preoperative level in all groups(P<0.05), and at the 3rd day after surgery was significantly lower than at the 1st day after surgery(P<0.05). After surgery, the eGFR_EPI_c level was significantly higher than the level before surgery in all groups (P<0.05), and at the 7th day after surgery was significantly higher than at the 1st day after surgery (P<0.05). The level of WBC in all patients after surgery was significantly higher than that before surgery(P<0.05), and the level at the 3rd and 7th day after surgery was significantly higher than that at the 1st day after surgery(P<0.05). At the 7th day after surgery, the energy and protein intakes of the patients were significantly lower than the recommendations. There was positive correlation between preoperative BMI and TP, ALB levels at the 1st postoperative day and the TP level at 3rd postoperative day(P<0.05). There was no direct correlation between preoperative BMI and the length of postoperative hospital stay (P>0.05). The length of postoperative hospital stay was negatively correlated with the age and negatively with TP and ALB levels at the 1st postoperative day(P<0.05). CONCLUSIONS: Early postoperative nutritional status of patients with malignant oral and maxillofacial neoplasms complicated with diabetes mellitus decreased significantly. The energy and protein intakes of the patients are significantly lower than the recommendations. The length of postoperative hospital stay is negatively correlated with early postoperative nutritional status and age.

RESUMO

The aim of the present study was to investigate the prevalence of excess weight and associated factors in women of reproductive age living in a low-income community. A cross-sectional study was conducted with a sample of 663 women 15 to 49 years of age residing in the neighborhood of Coelhos in the city of Recife, Brazil. Body mass index (BMI)-for-age was used to classify the nutritional status of the adolescents (15 to 19 years of age), adopting Z-score of ≥+1 for the definition of overweight. For the adults, BMI≥25.0 kg/m² was considered indicative of overweight. Socioeconomic, demographic and reproductive variables were analyzed as possible factors associated with overweight. The prevalence of excess weight was found in two thirds of the sample. The results of the Poisson multiple regression analysis showed a significantly higher prevalence of excess weight with the advance in age, among those with a younger menarche age, those who had three or more pregnancies, those living with their partner and those self-declared black or white. Multiparity was the only factor associated with excess weight that could be modified, which underscores the importance of prenatal and family planning services to its prevention and control.

RESUMO

The scope of this article is to associate breakfast consumption (BC) with moderate to vigorous physical activity (MVPA) intensity and the nutritional status of children aged 9-11. The sample consisted of 432 children from São Caetano do Sul participating in the International Study of Childhood Obesity Lifestyle and the Environment. Data were collected between 2012 and 2013. The weekly BC was obtained using the self-reported method. To measure MVPA, children used accelerometers and were classified into two groups (<60 versus ≥60 min/day). The nutritional status was presented by body mass index (BMI). Logistic regression models were used, adjusted for gender, age, race, parental educational level and eating score. The mean BC was 5.25 (CI95%: 5.1-5.4) days/week and the MVPA was 59.29 (CI95%: 57.3-61.7) min/day. In the total sample, 55.8% of the children did not perform ≥60 min/day of MVPA and 50.2% were overweight or obese. The daily BC was not associated with MVPA, however, it reduced the odds of children being overweight or obese (OR: 0.51; CI95%: 0.34-0.76; p=0.001). Daily BC reduced the odds of excess weight or obesity in children, though it did not increase the chances of children meeting the recommendations of MVPA. Public policies should encourage daily BC to prevent excess weight or obesity.

RESUMO

Over the course of the past few decades, the scientific rationale on nutrition has consolidated, intensifying the dissemination of dietary norms that dictate what and when to eat to guarantee good health. There is an increase in the interconnection between dietary norms and sociocultural norms. This study seeks to understand this link through the analysis of discourses of Brazilian, Spanish and French dietitians and laywomen. With this in mind, the sociocultural and dietary norms related to the midday meal were analyzed. Comparative and qualitative synchronous methodology, based on 131 semi-structured individual interviews, was used. The discourses of the informants were cross-checked with the public health messages on nutrition of each country. The analyses revealed that each nationality has particular codes that define the specifics of each meal, from the sociocultural and dietary point of view. The definition of a "healthy" meal depends on factors ranging from the nutritional and physiological to the social, cultural and symbolic dimensions linked to each meal model, determining the rituals, frequency, use and classification of food products. Thus, the norms that define what is perceived as healthy similarly result from sociocultural normative systems.

RESUMO

The article describes methodological aspects in defining the study population, sampling plan, and sample weigthing and calibration of effective sample of the Brazilian National Survey on Child Nutrition (ENANI-2019). This population-based household survey assessed breastfeeding and dietary intake, anthropometric assessment of nutritional status, and micronutrient deficiencies by blood biomarkers in children under five years of age. The data were obtained with a probability sample, with stratification by the five geographic regions in the country and clustering by census enumeration areas (CEAs). The sample was calculated at 15,000 households distributed in 1,500 CEAs, with 300 allocated in each of Brazil's five major geographic regions and 10 eligible households per CEA, sampled using inverse sampling. The required population parameters were thus estimated to reach the study's objectives. The basic sampling design weights were calculated as the inverse probabilities of the households' inclusion in the study. Imputation was used to compensate for non-response to items in the target variables, except for data on the blood biomarkers. Finally, calibration used population totals of children in 60 post-strata, defined by cross-classification of the following variables: major geographic region, sex, and age. The final sample included 14,558 children residing in 12,524 households, distributed in 1,382 CEAs in the 26 states of Brazil and the Federal District. The data from the ENANI-2019 survey will support strategies for the promotion and implementation of public policies for children under five years of age.

RESUMO

Nowadays alimentary dystrophy (dystrophia alimentaris), which can develop for a variety of reasons, remains an urgent problem in modern medicine, particularly in patients with head and neck tumors. Several methods of experimental food deprivation are known today (Kosmatykh T.A. et al. 2001, Khoroshykh N.V. 2010, Gembarovskyi M.V. 2013, Koropetska N.Yu. et al., 2015) but all of them have certain limitations which make impossible the comparison between the experimental study results and clinical data. The aim of the study was to develop an experimental rat model of alimentary dystrophy based on partial food deprivation which would allow to identify the limits and levels of compensated states of dystrophy with possible restoration of protein metabolism. Influence of complete and partial alimentary deprivation on animals' physical condition was experimentally studied on 40 male rats divided into four groups. Group I included rats kept on complete food deprivation; group II - rats on partial deprivation (1/2 of daily diet); group III - rats receiving 1/3 of daily diet; group IV - intact rats (control group) on regular daily diet. Changes in animals' weight during study period were assessed. After completion of food deprivation period, behavioral activity of the animals was registered using the standard open field test; ambulation and emotional status of subjects were studied. After withdrawal of the subjects from experiment, biochemical parameters of blood (albumin, total protein, glucose levels) were evaluated as indicators of general condition of the animals. An optimal model of alimentary dystrophy has been developed which seems to be beneficial in studying various schemes of supplementary nutrition. It is hoped that the results of this study could be used in developing management strategy for correction of supplementary nutrition in case of alimentary dystrophy.

RESUMO

BACKGROUND: A previous study suggested an association between low caloric intake(CI), negative nitrogen balance, and poor outcome after subarachnoid hemorrhage(SAH). Objective of this multinational, multicenter study was to investigate whether clinical outcomes vary by protein intake(PI) or CI in SAH patients adjusting for the nutritional risk as judged by the modified NUTrition Risk in the Critically Ill (mNUTRIC) score. METHODS: The International Nutrition Survey(INS) 2007-2014 was utilized to describe the characteristics, outcomes and nutrition use. A subgroup of patients from 2013 and 2014(when NUTRIC score was captured) examined the association between CI and PI and time to discharge alive(TTDA) from hospital using Cox regression models, adjusting for nutrition risk classified by the mNUTRIC score as low(0-4) or high(5-9). RESULTS: There were 489 SAH patients(57% female with a mean ± SD age 57.5 ± 13.9 years, BMI of 25.9 ± 5.3 kg/m2 and APACHE-2 score 19.4 ± 7.0. Majority(85%) received enteral nutrition(EN) only, with a time to initiation of EN of 35.4 ± 35.2 hours. 64% had EN interrupted. Patients received a CI of 14.6 ± 7.1 calories/kg/day and PI 0.7 ± 0.3 grams/kg/day corresponding to 59% and 55% of total prescribed CI and PI respectively. In the 2013 and 2014 subgroup there were 226 SAH patients with a mNUTRIC score of 3.4 ± 1.8. Increased CI and PI were associated with faster TTDA among high mNUTRIC patients(HR per 20% of prescription received = 1.34[95% CI,1.03 -1.76] for CI and 1.44[1.07 -1.93] for PI), but not low mNUTRIC patients(CI: HR = 0.95[0.77 -1.16] PI:0.95[0.78 -1.16]). CONCLUSIONS: Results from this multicenter study found that SAH patients received under 60% of their prescribed CI and PI. Further, achieving greater CI and PI in hi risk SAH patients was associated with improved TTDA. mNUTRIC serves to identify SAH patients that benefit most from artificial nutrition and efforts to optimize protein and caloric delivery in this subpopulation should be maximized.

RESUMO

This article aims to present general methodological aspects of the Brazilian National Survey on Child Nutrition (ENANI-2019), from the conception of the study design to details of the data collection. This is a household-based population survey with a sample calculated at 15,000 households to identify children under five years of age, conducted in 123 municipalities in Brazil's 26 states and the Federal District. ENANI-2019 includes data on breastfeeding and dietary intake; anthropometric nutritional status of all children and their biological mothers; and nutritional status concerning the following micronutrients: iron (hemoglobin and ferritin), zinc, selenium, and vitamins A, B1, B6, B12, D, E, and folic acid of children from 6 to 59 months of age. A total of 193,212 households were visited, of which 19,951 were eligible, and 12,524 were included in the study. A total of 14,558 children were studied, of whom 13,990 (96.1%) and 13,921 (95.6%) had their body mass and length/stature measured, respectively, and 14,541 (99.9%) underwent 24-hour dietary recalls (24HR). Of the 12,598 children eligible for blood sample collection, 8,739 (69.3%) had at least one laboratory parameter measured. Data were collected from February 2019 to March 2020, when the survey was interrupted due to the COVID-19 pandemic. The evidence produced by the ENANI-2019 survey can back the formulation, follow-up, and/or reorientation of food and nutrition policies such as the promotion of breastfeeding and healthy eating and the prevention and control of different forms of malnutrition.

RESUMO

Objective: To study and explore the prevalence, characteristics, preliminary risk factors, as well as their relationship with nutritional scores in liver cirrhotic patient with chronic periodontitis. Methods: 163 patients with liver cirrhosis who were hospitalized in the Hepatology Division, Department of Internal Medicine at Tianjin Third Central Hospital from June to September 2018 were enrolled as the case group, while the control group consisted 140 healthy individuals enrolled during the same period. Periodontal examination, biochemical examination and oral hygiene habits were investigated. The prevalence of periodontitis in the two groups was compared, and the risk factors of severe periodontitis were conducted by multivariate regression analysis. Results: The prevalence of chronic periodontitis was significantly higher in patients with liver cirrhosis than healthy control population, and the differences were statistically significant (P < 0.05). The prevalence of severe periodontitis and full edentulous jaws was significantly higher in patients with liver cirrhosis than healthy control group, and the differences were statistically significant (P < 0.05 and P < 0.001). Compared with the healthy control group, the depth of periodontal pocket and the degree of attachment loss were significantly increased in the liver cirrhosis group (P < 0.001). Multivariate regression analysis showed that liver cirrhosis was the independent risk factors for both groups of patients with severe periodontitis (χ (2) = 11.046, P < 0.001). Univariate and multivariate regression analysis showed that toothbrushing frequency, nutritional risk score, prealbumin level and Child-Pugh grade were independent risk factors for occurrence of severe periodontitis in liver cirrhotic patient (χ (2) = 5.252, P = 0.022; χ (2) = 24.162, P < 0.001; χ (2) = 4.159, P = 0.041; χ (2) = 9.249, P = 0.002). Conclusion: The prevalence of periodontitis is significantly higher in patients with liver cirrhosis than healthy individuals, and liver cirrhosis is an independent risk factor for the occurrence of severe periodontitis. Toothbrushing frequency, nutritional risk score, prealbumin level and Child-Pugh grade are risk factors for severe periodontitis in patients with liver cirrhosis.
