Muscle and bone have been considered a functional unit that grows together early in life, deteriorates with aging, and can cause osteosarcopenia. Due to its importance in public health, detecting risk factors in early life is desirable. This study examined whether birth weight (BW) was associated with muscle–bone unit using dual energy X-ray absorptiometry (DXA) parameters in young women from the Nutritionists’ Health Study (NutriHS), a cohort study of undergraduates and Nutrition graduates. This cross-sectional analysis included 170 young healthy women who answered early life events-questionnaire, and had anthropometric, muscle tests and DXA-determined body composition and bone densitometry (iDXA-Lunar®). A blood sample was obtained for a subsample of 148 participants. Appendicular skeletal muscle mass index (ASMI) was calculated. BW was categorized in quartiles (BWq) and variables of interest compared by ANOVA. Associations of BWq with calf circumference (CC), handgrip, muscle performance tests, ASMI, bone mineral density and content (BMD and BMC), and plasma glucose, lipids, insulin, and 25-hydroxyvitamin D were performed using multiple linear regression and directed acyclic graph-recommended adjustments. Mean values of age, body mass index, and BW were 23.0 years (20.0–28.0), 22.9 ± 2.9 kg/m2, and 3199 ± 424 g, respectively. Comparing variables across BWq, significant differences in CC, handgrip, ASMI, and total body BMC were detected. Regression models adjusted for confounders showed associations of BWq with CC (β = 0.72, p = 0.005), handgrip (β = 1.53, p = 0.001), ASMI (β = 0.16, p = 0.022), total body BMC (β = 64.8, p = 0.005), total femur BMC (β = 0.70, p = 0.041), total body BMD (β = 0.02, p = 0.043), and lumbar spine BMD (β = 0.03, p = 0.028). We conclude that BW is associated with muscle–bone unit using DXA-parameters in Brazilian young healthy women from the NutriHS, suggesting a role for intrauterine environment for musculoskeletal health.

Objective:To investigate the association between maternal pre-pregnancy BMI and offspring body composition in adulthood.Design:Retrospective cohort. Undergraduates of nutrition or nutritionists were recruited at the baseline of the Nutritionists’ Health Study between 2014 and 2017. Maternal pre-pregnancy BMI and current life aspects were self-reported through online questionnaires. Three body compartments were dual-energy x-ray absorptiometry-determined. The following variables were obtained: body fat (%), fat mass index (FMI) (kg/m2), android-to-gynoid fat ratio, visceral adipose tissue (VAT) (cm3), appendicular skeletal muscle mass index (ASMI) (kg/m2), total bone and femur mineral content (g) and density (g/cm2). Linear regression adjusted according to directed acyclic graphs recommendation was performed.Setting:São Paulo, Brazil.Participants:Healthy non-pregnant women (aged 20–45 years) (n 150).Results:Median age and BMI were 22 years (IQR = 20, 29) and 22·3 kg/m2 (IQR = 20·4, 25·3), respectively. Pre-pregnancy BMI ≥ 25 kg/m2 was reported by 14·7 % of mothers. In fully adjusted models, maternal pre-pregnancy BMI was associated with their daughters’ body fat % (β = 0·31; 95 % CI 0·0004, 0·63), FMI (β = 0·17; 95 % CI 0·03, 0·30), android-to-gynoid ratio (β = 0·01; 95 % CI 0·004, 0·02) and VAT (β = 0·09; 95 % CI 0·02, 0·16), but not with total bone density (β = 0·001; 95 % CI –0·003, 0·006) and content (β = 7·13; 95 % CI –4·19, 18·46). Direct association with ASMI was also detected, but lost statistical significance when participants whose mothers were underweight were excluded.Conclusions:Maternal pre-pregnancy BMI was directly associated with offspring general and visceral adiposity but seems not to be associated with bone mass. Results reinforce importance of avoiding excess of maternal adiposity, as an attempt to break the vicious cycle of obesity transmission.

Objective: To compare components of glycemic and energy homeostasis in women with metabolically healthy normal weight (MHNW) and metabolically unhealthy (MUNW), metabolically unhealthy overweight/obese (MUO) and metabolically healthy (MHO) phenotypes. Methodology: Cross-sectional study with 104 women (18-45 years): 30 MHNW, 17 MUNW, 27 MHO, 30 MUO. Overweight was considered BMI ≥ 25 kg/m² and metabolic health without of changes in blood pressure, glycemic, lipemic levels and cardiovascular disease. The standard mixed meal tolerance test and indirect calorimetry were performed (assessments at -15, 0, 30, 60, 120 and 180 min). The quantifications were: areas under the curve (AUC) for glucose, insulin, C peptide, glucagon and GLP-1; insulin sensitivity (IS) by oral glucose insulin sensitivity index; energy expenditure, respiratory quotient, and carbohydrate and lipid oxidation rate were measured at rest and after oral stimulation. Results: The groups did not differ regarding age and HbA1c levels. IS was decreased in MUO compared to MHNW and MHO (p Conclusion: In young and normoglycemic women, there was lower IS and insulin secretion for the MUO phenotype. The greater rate of lipid oxidation in this group compared to the lean ones may be a reflection of the lower IS, and the inability to switch the use of energy substrate to the higher carbohydrate availability after oral stimulation. BMI is not an ideal indicator of the presence or absence of metabolic health. However, even in MHO individuals’, physiological adaptations may happen to maintain the metabolic parameters within normal range. Disclosure F.B. Ribeiro: None. I. Solar: None. R.G. Freitas: None.

Introduction: Many studies report that environmental factors occurring in childhood may modulate the composition of the gut microbiota in adulthood, which in turn, produces short chain fatty acids (SCFA) with metabolic effects on inflammatory cascades associated with glycemic homeostasis. Objective: This study aims to analyze associations between type of delivery (vaginal/cesarean section), type of breast-feeding (maternal/artificial) and solid food introduction (start and quality) with fecal SCFA concentrations in women. Method: A cross-sectional study including 106 women, 28±5 years old and BMI 25±5 kg/m2, a questionnaire regarding from birth until the first year of life. For quantification of acetate, butyrate and propionate it was used gas chromatography-mass spectrometry in fecal samples. Results: Of the women surveyed 63% were cesarean delivered and 93% received maternal breast milk at some point. There was no correlation between SCFA concentration and type of delivery (p>0.05). Positive correlation was found between breastfeeding time and butyrate (r=0.24; p=0.02), there was a tendency with propionate (r=0.20; p=0.06). There was no correlation between time received infant formula and SCFA. There was a tendency of correlation between butyrate and beginning of cow’s milk intake (r=0.194; p=0.052). Age at solid food introduction correlates with propionate (r=0.22; p=0.026) and butyrate (r=0.25; p=0.012), and report a tendency with the acetate (r=0.18; p=0.07). In the first year of life, individuals who prefer salty crackers and pasta/potatoes had less concentration of propionate and acetate, respectively (p=0.026). Conclusion: The type of delivery was not associated with SCFA, but there was a favorable association with prolonged breastfeeding, late beginning of cow’s milk intake, introduction of solids starting after 6 months of age and lower intake of refined cereals.

A obesidade e caracterizada por uma doenca cronica nao transmissivel, podendo resultar em diferentes fenotipos metabolicos. Um dado de extrema importância para um bom planejamento na pratica clinica do nutricionista e o gasto energetico de repouso, podendo ser estimado por equacoes preditivas ou mensurado pela calorimetria indireta, metodo padrao-ouro. O presente trabalho e um estudo transversal, parte do Nutritionists Health Study - NutriHS, que teve como objetivo comparar o gasto energetico de repouso estimado por 12 equacoes preditivas versus o mensurado por calorimetria indireta em 78 jovens mulheres agrupadas em quatro diferentes fenotipos metabolicos e de adiposidade corporal. Para os quatro grupos estudados, foi possivel observar que a equacao com melhor acuracia individual e populacional foi a de Owen 2, que leva em consideracao a composicao corporal do individuo. A maioria das equacoes comumente utilizadas superestimaram o gasto energetico de repouso em mais de 50%, sugerindo que sua utilizacao na pratica clinica e em pesquisa deve ser feita com cautela.

A obesidade e uma doenca multifatorial associada a diversas comorbidades. Com prevalencia crescente, torna-se fundamental a avaliacao nutricional nestes individuos. Novos indices para avaliacao da adiposidade corporal tem sido propostos como ferramentas de baixo custo, eficacia e praticidade¹²³. Objetivou-se avaliar se os indices de adiposidade corporal (IAC), de forma corporal (IFC), e massa gorda relativa (MGR) diferem dos marcadores antropometricos tradicionais (indice de massa corporal- IMC, circunferencia de cintura- CC e relacao cintura quadril- RCQ) na identificacao de um perfil metabolico desfavoravel e na avaliacao da adiposidade corporal em mulheres.

BACKGROUND/OBJECTIVES We investigated if breastfeeding duration and current dietary patterns (DP) were associated with glucose and lipid metabolism biomarkers in women from the Nutritionist's Health Study. SUBJECTS/METHODS This is a cross-sectional analysis of 200 healthy undergraduates and nutrition graduates aged ≤45 years. Total [

Background: Association of excessive visceral adipose tissue(VAT) with cardiometabolic risk in middle-aged adults has been recognized. VAT determined by dual-x-ray absorptiometry(DXA) is an accurate measurement but its usefulness for early detection of cardiovascular risk at a younger age is less investigated. The NutriHS has examined several cardiometabolic markers in undergraduates and graduates from Nutrition courses in Brazil. Aim: To evaluate whether DXA-VAT is associated with cardiometabolic markers in young adults with a normal cardiovascular risk profile. Methods: In this cross-sectional analysis, 177 NutriHS participants(90% women, 70% Caucasians) underwent clinical examination, body composition(iDXALunarGE®) and blood sampling. Associations of DXA-VAT(exposure) with blood pressure(BP), waist and neck circumferences(WC and NC), BMI, triglycerides(TG), HDL-c, non-HDL-c, uric acid, fasting glucose, insulin, HOMA-IR and inflammatory biomarkers(outcomes) were tested by multiple linear regression, adjusted according to the directed acyclic graphs. Results: Mean values of age, BMI and FG were 25.8±8.0years, 23.5±4.3kg/m2 and 83±9mg/dL, respectively. DXA-VATs were 693.6±640.3g for men and 235.7±322.6g for women. In regression models, DXA-VAT was directly associated with NC(r2 0.62, p Conclusion: Such associations of DXA-VAT with traditional and novel risk markers suggest that this method may be useful to identify those at an increased risk even in a selected sample of low-risk healthy individuals. Our follow-up is necessary to confirm the hypothesis raised in this study. Disclosure A.M.M. Valente: None. B. Almeida-Pititto: None. A.A. Ferraro: None. L. Folchetti: None. I.T. Silva: None. S.R.G.

Due to immunomodulatory properties, vitamin D status has been implicated in several diseases beyond the skeletal disorders. There is evidence that its deficiency deteriorates the gut barrier favoring translocation of endotoxins into the circulation and systemic inflammation. Few studies investigated whether the relationship between vitamin D status and metabolic disorders would be mediated by the gut microbiota composition.We examined the association between vitamin D intake and circulating levels of 25(OH)D with gut microbiota composition, inflammatory markers and biochemical profile in healthy individuals.In this cross-sectional analysis, 150 young healthy adults were stratified into tertiles of intake and concentrations of vitamin D and their clinical and inflammatory profiles were compared. The DESeq2 was used for comparisons of microbiota composition and the log2 fold changes (log2FC) represented the comparison against the reference level. The association between 25(OH)D and fecal microbiota (16S rRNA sequencing, V4 region) was tested by multiple linear regression.Vitamin D intake was associated with its concentration (r=0.220, p=0.008). There were no significant differences in clinical and inflammatory variables across tertiles of intake. However, lipopolysaccharides increased with the reduction of 25(OH)D (p-trend0.05). Prevotella was more abundant (log2FC 1.67, p0.01), while Haemophilus and Veillonella were less abundant (log2FC -2.92 and -1.46, p0.01, respectively) in the subset with the highest vitamin D intake (reference) than that observed in the other subset (first plus second tertiles). PCR (r=-0.170, p=0.039), E-selectin (r=-0.220, p=0.007) and abundances of Coprococcus (r=-0.215, p=0.008) and Bifdobacterium (r=-0.269, p=0.001) were inversely correlated with 25(OH)D. After adjusting for age, sex, season and BMI, 25(OH)D maintained inversely associated with Coprococcus (β=-9.414, p=0.045) and Bifdobacterium (β=-1.881, p=0.051), but significance disappeared following the addition of inflammatory markers in the regression models.The role of vitamin D in the maintenance of immune homeostasis seems to occur in part by interacting with the gut microbiota. The attenuation of association of bacterial genera by inflammatory markers suggests that inflammation participate in part in the relationship between the gut microbiota and vitamin D concentration. Studies with appropriate design are necessary to address hypothesis raised in the current study.

Introduction Non-communicable chronic diseases (NCCDs) represent a burden for public health. Alongside the established cardiometabolic risk factors such as high blood pressure and disorders of glucose and lipid metabolism, living habits and nutritional status at different stages of life are seen as contributors to this scenario. Gut microbiota composition and subclinical inflammation have been pointed out as underlying mechanisms of NCCDs. Studies involving health professionals have brought relevant contributions to the knowledge about risk factors. Technological advances facilitate data collection and analysis for big samples. A web-based survey addressed to collect data from a cohort study, which is able to identify NCCDs risk factors, is highly desirable. The objective of the Brazilian Nutritionists’ Health Study (NutriHS) is to gather online information on early life events, daily habits, emergent cardiometabolic risk factors and health outcomes of a specific subset of the Brazilian population. Methods and analysis NutriHS, developed at the School of Public Health—University of Sao Paulo, Brazil, is a research initiative that enrols undergraduates of nutrition courses from Brazilian universities and graduated volunteers. A web-based self-administered system was designed to collect health-related data. After fulfilling online questionnaires (socioeconomic, early life events and lifestyle data), participants are invited to a clinical visit for physical examination and laboratory procedures (blood sampling, faeces collection and body composition). At a 3-year interval, they will be invited to repeat similar procedures. Ethics and dissemination The NutriHS research protocol was approved by the Institutional Ethics Committee and is providing promising data which contribute to the understanding of pathophysiological links between early life events, body composition, gut microbiota, and inflammatory and metabolic risk profile. The combination of a friendly tool with the innovative purposes of NutriHS offers a remarkable resource for testing hypotheses about mechanisms of nutrition-related diseases and further planning of preventive programmes in public health.

Objectives Associations of leisure-time physical activity (LTPA), commuting and total physical activity with inflammatory markers, insulin resistance and metabolic profile in individuals at high cardiometabolic risk were investigated. Design This was a cross-sectional study. Methods A total of 193 prediabetic adults were compared according to physical activity levels measured by the international physical activity questionnaire; p for trend and logistic regression was employed. Results The most active subset showed lower BMI and abdominal circumference, reaching significance only for LTPA (p for trend = 0.02). Lipid profile improved with increased physical activity levels. Interleukin-6 decreased with increased total physical activity and LTPA (p for trend = 0.02 and 0.03, respectively), while adiponectin increased in more active subsets for LTPA (p for trend = 0.03). Elevation in adjusted OR for hypercholesterolemia was significant for lower LTPA durations (p for trend = 0.04). High apolipoprotein B/apolipoprotein A ratio was inversely associated with LTPA, commuting and total physical activity. Increase in adjusted OR for insulin resistance was found from the highest to the lowest category of LTPA (p for trend = 0.04) but significance disappeared after adjustments for BMI and energy intake. No association of increased C-reactive protein with physical activity domains was observed. Conclusions In general, the associations of LTPA, but not commuting or total physical activity, with markers of cardiometabolic risk reinforces the importance of initiatives to increase this domain in programs for the prevention of lifestyle-related diseases.

OBJETIVO: Este estudo comparou parâmetros antropométricos e de resistência à insulina de indivíduos sem e com síndrome metabólica (SM), subestratificados pela presença de anormalidades glicêmicas. SUJEITOS E MÉTODOS: Foram incluídos 454 indivíduos (66% mulheres, 54% brancos), sendo 155 alocados para o grupo 1 (sem SM, sem anormalidade glicêmica), 32 para o grupo 2 (sem SM, com anormalidade glicêmica), 104 no grupo 3 (com SM, sem anormalidade glicêmica) e 163 no grupo 4 (com SM e anormalidade glicêmica). Os grupos foram comparados por ANOVA. RESULTADOS: Os grupos com SM (3 e 4) apresentaram os piores perfis antropométrico e lipídico; no grupo 2, apesar de glicemias significantemente mais elevadas, as médias das variáveis antropométricas e lipídicas não diferiram do grupo 1. Os maiores valores médios de HOMA-IR foram encontrados nos grupos com SM, enquanto o grupo 2 apresentou o menor HOMA-β. A trigliceridemia foi a variável metabólica com coeficientes de correlação mais elevados com a antropometria. Porém, as correlações mais fortes foram da circunferência da cintura (r = 0,503) e da razão cintura-altura (r = 0,513) com o HOMA-IR (p < 0,01). CONCLUSÃO: Nossos achados revelam que, em amostra da população brasileira, qualquer das medidas antropométricas identifica indivíduos com SM, mas não parece capaz de diferenciar aqueles com distúrbio glicêmico. Reforçamos a relação mais forte das medidas de adiposidade central com resistência à insulina, sugerindo utilidade da razão cintura-altura. É possível que componente autoimune contribua para o comprometimento do metabolismo glicídico dos indivíduos do grupo 2.

Objective This study aimed to compare the effects of two lifestyle intervention programs for type 2 diabetes mellitus (T2DM) prevention – traditional or interdisciplinary psychoeducation-based intervention – in daily habits and cardiometabolic risk factors and investigate the role of the psychoeducational approach for the retention of individuals in the program. Subjects and methods Between 2008 and 2010, in a public health service, 183 pre-diabetic individuals were allocated to two 18-month interventions involving diet and physical activity. Physical activity, diet, quality of life (QOL) and depression and biochemical measurements were obtained. Linear mixed-effect models were used to assess the effect of the interventions. A student t test was used to compare dropouts versus non-dropouts. Results Improvements in energy intake and physical activity were greater in the interdisciplinary than the traditional intervention. A decrease in fat mass and blood pressure was more pronounced with interdisciplinary intervention. Dropouts from the traditional intervention only had higher BMI and lower fiber intake and QOL than non-dropouts. Conclusion The interdisciplinary psychoeducation-based intervention revealed useful for reducing cardiometabolic risk and retaining individuals with worse health profiles. This approach represents a feasible strategy for motivating high-risk individuals to adopt a long-term healthy lifestyle.

This study describes a web-based system developed to gather online information on health of college students and graduates in nutrition, the e-NutriHS. The Nutrititionist Health Study – NutriHS is planned to be a cohort study aiming to collect health-related data at a 3-year interval. The e-NutriHS consists of 6 questionnaires regarding demographic and socioeconomic data, dietary habits, physical activity, alcohol and tobacco uses, anti-fat attitudes and personal and family histories. Validated and internationally recognized lifestyle instruments were used. Our software and respective database are hosted in the School of Public Health server; the software is based on free programming languages. e-NutriHS data obtained from questionnaires can be transferred to excel format. An e-NutriHS prototype was created preceding online attachment. An improved version of website was released based on 20 volunteers’ opinions. 503 users were already registered. Our initiative of building a website designed for collecting data for epidemiological studies, tailored to our local reality, is innovative under the perspective of the health informatics available in the developing world. Considering that web-based systems produce reliable data, are easy to use, less costly and less time-consuming, we conclude that our experience deserves to be shared, particularly with middleincome economy countries.

We investigated whether diet quality was associated with leisure-time physical activity (LTPA) and television viewing and the associations of these variables with traditional cardiovascular risk factors and novel biomarkers in individuals at cardiometabolic risk.A total of 193 prediabetic adults (63.7% women, mean age 54.1 years), screened for a diabetes prevention program in Brazil, participated in this cross-sectional study. Clinical data and blood samples were collected for several determinations. Twenty-four-hour recalls were used to calculate the Healthy Eating Index (HEI) adapted to Brazilian dietary habits and the International Physical Activity Questionnaire to assess physical activity level. Analysis of covariance with adjustments for age and body mass index (BMI) was employed to test associations across categories of LTPA and television viewing.Stratifying according to LTPA categories, the most active subset (≥150 minutes/week) showed better HEI scores after adjustments (64.6 ± 11.0, 65.1 ± 10.3, and 68.6 ± 10.8, p = 0.02) and significant higher values of dark green and orange vegetables but not of whole grains (p = 0.06). Active individuals had lower BMI, waist circumference, inflammatory markers, and better insulin sensitivity (p0.05). Individuals at the highest category of television viewing had higher age-adjusted BMI (32.0 ± 6.2, 30.7 ± 6.0, and 28.8 ± 4.7 hours/week; p = 0.01) than the others. Time watching television was inversely associated with homeostasis model assessment (HOMA-IR) and C-reactive protein (CRP; p0.01) after adjustments but not with lipids and HEI score. Comparisons of individuals with healthy habits (better diet and higher physical activity [PA]), with those with unhealthy habits revealing better anthropometric and cardiometabolic profiles in the former group.Diet quality assessed by the HEI adapted for Brazilian eating habits attained significance in differentiating more active from inactive at-risk individuals during leisure time. Time watching television, as a surrogate of sedentary behavior, is not useful to detect unhealthy diet quality. LTPA is indicative of better cardiometabolic profile reflected by lipid and inflammatory markers and index of insulin resistance.

Background Dietary guidelines of 5 servings per day of fruits and vegetables (FV) offer a reasonable amount of vitamins to control organic processes, which may contribute to a favorable cardiometabolic profile. This study aimed at investigating whether the intake of the FV group as well as pro-vitamin A carotenoids and vitamins C and E were associated with circulating markers of oxidative stress, inflammation and insulin resistance in Brazilians individuals at cardiometabolic risk. Methods This cross-sectional study included 205 individuals screened for diabetes prevention program in a healthcare center from the School of Public Health, University of São Paulo, conducted in 2008. Possible associations of consumption of FV group, as well as pro-vitamin A carotenoids and vitamins C and E, with circulating markers of oxidative stress (superoxide dismutase – SOD and oxidized LDL – oxLDL), inflammation (C reactive protein, TNF-α and adiponectin) and insulin resistance (HOMA-IR) were investigated. Pearson correlation coefficient, ANOVA and multiple linear regression were employed. Results The sample (64.7% women) had a mean age of 54.1 ± 12.7 years and body mass index of 30.7 ± 5.7 kg/m2. Dietary, physical activity, anthropometric and laboratory data were obtained. Participants consumed a mean of 3.8 servings/day of FV; their FV intake was categorized into three groups: 5.0 servings/day. Significant trends for lower waist circumference (103.4 ± 13.6 vs. 100.1 ± 12.2 vs. 98.2 ± 12.7 cm, p-trend

Background/objectives Cardioprotective effects of Mediterranean-style diet have been shown. Instead of excluding foods, replacement or addition may facilitate compliance with impact on glucose metabolism of individuals at cardiometabolic risk. This study investigated the effect of changing selected nutrients intake on glucose metabolism during a lifestyle intervention tailored to living conditions of prediabetic Brazilians. Subjects/methods 183 prediabetic adults treated under the Brazilian public health system underwent an 18-month intervention on diet and physical activity. Dietary counseling focused on reducing saturated fat replaced by unsaturated fatty acids. Data were collected at baseline and after follow-up. ANOVA and multiple linear regression were used to test association of changes in nutrients intake with changes in plasma glucose. Results Changes in fasting and 2-h plasma glucose but not in weight, HOMA-IR or C-reactive protein decreased after intervention across tertiles of MUFA changes (p-trend 0.017 and 0.024, respectively). Regression models showed that increase in MUFA intake was independently associated with reduction in fasting (β -1.475, p = 0.008) and 2-h plasma glucose (β -3.321, p = 0.007). Moreover, increase in soluble fibers intake was associated with decrease in fasting plasma glucose (β -1.579, p = 0.038). Adjustment for anthropometric measurements did not change the results but did after including change in insulin in the models. Conclusions Increases of MUFA and soluble fibers intakes promote benefits on glucose metabolism, independently of adiposity, during a realistic lifestyle intervention in at-risk individuals. Mechanisms mediating these processes may include mainly insulin sensitivity improvement.
