Validation and calibration of the Food Consumption Frequency Questionnaire for pregnant women

ABSTRACT BACKGROUND: Few food frequency questionnaires (FFQ) have been validated for pregnant women, particularly those in small- and medium-sized cities in different regions of Brazil. OBJECTIVES: To validate and calibrate a semiquantitative FFQ for pregnant women. DESIGN AND SETTING: The study was validated with a sample of 50 pregnant women (≥ 18 years) enrolled in Brazilian prenatal services. METHODS: An FFQ and a 24-hour recall were used to evaluate dietary intake. Dietary variables were tested for normality and log-converted when asymmetrical. Pearson's Correlation Coefficient was used to validate the questionnaire. Linear regression was applied to extract calibration factors. All variables underlying the consumption analysis were adjusted for energy. RESULTS: The mean age of the pregnant women was 26 years ± 6.2 years; 58% were in their first trimester, and 30% were identified as overweight/obese. The Pearson correlation analysis results indicated that the FFQ overestimated energy and nutrient intake, whose coefficients ranged from −0.15 (monounsaturated fat) to 0.50 (carbohydrate). Adjusting for energy reduced the mean values of intake coefficients, which now ranged from −0.33 (sodium) to 0.96 (folate). The calibration analysis results indicated variation in the coefficients from −0.23 (sodium) to 1.00 (folate). Calibration produced satisfactory coefficients for the FFQ compared with the reference standard for energy, macronutrients, monounsaturated fat, cholesterol, vitamins B12/C, folate, sodium, iron, and calcium. CONCLUSIONS: After validating and calibrating tests, we observed that the FFQ was adequately accurate for assessing the food consumption of the pregnant women in this study.

Dietary patterns associated with physical activity and sedentary behavior in university students in Mexico

Dietary patterns (DPs) are conditioned by a large number of factors, including physical activity and sedentary lifestyle, however, there is limited information on their interaction. This study aimed to identify DPs and their associations with physical activity and sedentary behavior among university students from Mexico. We conducted a cross-sectional, observational and analytical study. The participants were university students from Southwest Mexico. A total of 419 participants who did not suffer from any disease that affects oral nutrition or that prevented them from performing physical activity were included. DPs were generated from a principal component analysis and associations were analyzed using a logistic regression model. Three DPs were identified: "western", "prudent" and "traditional". The traditional pattern was significantly associated with high physical activity (OR: 2.78; 95% CI: 1.34-5.75) and was a protective factor against sedentary lifestyle (OR: 0.35; 95% CI: 0.13-0.93). The results show that a high physical activity and a lower sedentary lifestyle were associated with a healthier dietary pattern in the study population. It is important to implement interventions towards nutrition, physical activity and sedentary behavior for the population being studied.

Los patrones dietéticos están condicionados por una gran cantidad de factores, entre ellos la actividad física y el sedentarismo, sin embargo, existe poca información sobre su interacción. Este estudio tuvo como objetivo identificar patrones dietéticos y sus asociaciones con la actividad física y el comportamiento sedentario entre estudiantes universitarios del suroeste de México. Se trata de un estudio transversal, observacional y analítico. Los participantes fueron estudiantes universitarios del suroeste de México. Se incluyeron un total de 419 participantes que no padecían alguna enfermedad que condicionara su nutrición oral, ni condición que les impidiera realizar actividad física. Se realizó un análisis de componentes principales para determinar los patrones dietéticos, mientras que se utilizó un modelo de regresión logística para verificar las asociaciones. Se identificaron tres patrones dietéticos: "occidental", "prudente" y "tradicional". El patrón tradicional se asoció significativamente con actividad física elevada (OR: 2,78; IC 95%: 1,34-5,75) y fue un factor protector contra el sedentarismo (OR: 0,35; IC 95%: 0,13-0,93). Los resultados muestran que una alta actividad física y un menor sedentarismo se asociaron con un patrón dietético más saludable en la población de estudio. Es importante implementar intervenciones hacia la nutrición, la actividad física y el sedentarismo para la población en estudio.

Correlation analysis between balanced diet nutrition and children's health in children aged 6-17 / 公共卫生与预防医学

Objective To understand the dietary structure and nutritional characteristics of children aged 6-17 under the mode of collective feeding and self-catering in schools, and their effects on children's health-related indicators. Methods From January to April 2022, stratified sampling method was used to select 2 collective feeding schools and 2 non-feeding schools in Baoshan District of Shanghai City, and finally 1 538 school-age children aged 6-17 were selected. Then, the “3-day 24-hour dietary review method” and “eighing method” were used to carry out the survey, and combined with the “Chinese Residents' Balanced Diet Pagoda (2016)” and “Chinese Residents' Dietary Nutrient Reference Intakes (DRIs 2013)” standards to analyze the Food intake and energy supply ratio of the three major nutrients. At the same time, on-site sampling was conducted on the last day to collect samples of children's height, weight, blood pressure, blood, etc, and analyze the changes of students' obesity, anemia, blood lipids and other routinely available indicators. Results Compared with the school group feeding mode, the students in the self-dining mode had a higher rate of insufficient intake of cereals, potatoes and vegetables; and the latter students had a higher intake of aquatic products. high (P28.0) was 3.8%, the rate of high TG was 7.3%, the rate of hypertension was 1.9%, and the rate of iron deficiency anemia was 2.6%, bone calcium loss rate was 2.8%, hyperglycemia rate was 5.1%. In addition, pearson correlation analysis showed that the intake of cereals and potatoes was positively correlated with BMI (r=0.348) and systolic blood pressure (r=0.438), and the intake of salt was also positively correlated with systolic blood pressure (r=0.472). ), while the intake of aquatic products was negatively correlated with the change of BMI value (r=-0.331). Conclusion Children aged 6-17 have insufficient intake of vegetables , aquatic products, soybeans and nuts in their diets. In addition, they need to pay attention to the intake of salt to prevent the occurrence of adverse health problems such as obesity and hyperlipidemia in children.

Dietary patterns associated with the risk of type 2 diabetes in women with and without a history of gestational diabetes mellitus: A pilot study

@#Introduction: There is limited evidence on dietary patterns and the risk of type 2 diabetes (T2D) in women with a history of gestational diabetes mellitus (GDM) compared to their non-GDM counterparts, especially in the Asian population. The pilot study investigated dietary patterns in women with a history of GDM (HGDM) and without a history of GDM (non-HGDM), and the association with T2D risk. Methods: This comparative cross-sectional study involved 64 women (32 HGDM, 32 non-HGDM). Food intake was assessed using a validated food frequency questionnaire. Principal component analysis derived the dietary patterns. T2D risk score was determined using the Finnish Diabetes Risk Score tool. Results: HGDM group had significantly higher proportion of first-degree family history of diabetes; higher risk of T2D and better diabetes knowledge; lower gestational weight gain and postpartum weight retention; and consumed more fast food than nonHGDM. ‘Rice-noodle-pasta-meat’ dietary pattern was significantly associated with increased T2D risk after adjusting for age (β=0.272, p=0.032). ‘Bread-cereals-fast food-meat’ dietary pattern was positively and significantly associated with T2D risk after adjusting for confounders, including age, education level, family history of diabetes, diabetes knowledge score, gestational weight gain, and postpartum weight retention (β=0.251, p=0.012). Conclusion: Dietary patterns high in bread, cereals and cereal products, fast food and meat, as well as rice, noodle, pasta and meat were associated with an elevated T2D risk. A more extensive study is warranted to establish the association between dietary patterns and risk of T2D, focusing on women with a history of GDM.

The contribution of prenatal care in the dietary patterns of high-risk pregnant women / A contribuição do acompanhamento pré-natal nos padrões alimentares de gestantes de alto risco

Abstract Objectives: investigate whether prenatal characteristics were associated with dietary pattern of pregnant women. Methods: we studied 200 high-risk pregnant women in Fortaleza, Ceará. The identification of dietary patterns was performed through principal component analysis with the orthogonal Varimax rotation. Poisson regression was used to estimate prevalence ratios (PR) and respective confidence intervals (CI95%). Results: three major dietary patterns were identified: 'common Brazilian', 'healthy' and 'energy-dense'. After adjustments conducted with multivariate analysis, pregnant women who had not received dietary guidance in prenatal consultations (34%) were less likely to adhere to the 'healthy' pattern (PR = 0,81; CI95%= 0,67-0,95). Pregnant women who attended an appropriate number of consultations (≥ 6 consultations) (41%) showed greater adherence to the 'healthy' pattern (PR = 1,15; CI95%= 1,01-1,32) and lower adherence to the 'energy-dense' pattern (PR = 0,85; CI95%= 0,74-0,99). Conclusion: it was observed that the high-risk pregnant women who attended an adequate number of consultations during the prenatal care had a higher chance to adhere to the 'healthy' pattern and a lower chance to adhere to the 'energy-dense' pattern. Not receiving guidelines on prenatal nutrition was inversely associated with the healthy pattern. Thus, the importance of high-risk pregnant women undergoing an appropriate prenatal care is reinforced.

Resumo Objetivos: investigar o efeito potencial das características de acompanhamento do pré-natal em padrões alimentares identificados em gestantes de alto risco. Métodos: foram estudadas 200 gestantes de alto-risco de Fortaleza, Ceará. Os padrões alimentares foram identificados pela análise de componentes principais seguida de rotação ortogonal Varimax. Utilizou-se Regressão de Poisson para estimar as razões de prevalência (RP) e os intervalos de confança (IC95%). Resultados: três padrões alimentares foram identificados: 'comum brasileiro', 'saudável' e 'denso em energia'. Após a realização de ajuste com análise multivariada, as gestantes que não receberam orientação sobre alimentação nas consultas do pré-natal (34%) apresentaram menores chances de adesão ao padrão 'saudável' (RP = 0.81, IC95%= 0.67-0.95). Aquelas que realizaram um número de consultas adequado (≥ 6 consultas) (41%) apresentaram maior adesão ao padrão 'saudável' (RP = 1.15, IC95%= 1.01-1.32) e menor adesão ao padrão 'denso em energia' (RP = 0.85, IC95%= 0.74-0.99). Conclusão: observou-se que as gestantes de alto risco que compareceram a um número adequado de consultas no pré-natal tiveram maior chance de aderir ao padrão 'saudável' e menor chance de aderir ao padrão 'denso em energia'. Não receber orientações sobre nutrição durante o pré-natal foi inversamente associado ao padrão 'saudável'. Reforçando a importância das gestantes de alto risco realizarem um pré-natal adequado.

Relação entre padrões alimentares e estado nutricional em universitários / Relationship between Food Standards and Nutritional Status in University Students / Relación entre estándares alimentarios y estado nutricional en estudiantes universitários

Introdução: A alimentação é um dos principais fatores para a promoção da saúde. Situações do meio acadêmico e estilo de vida propiciam aos universitários, dificuldades em cuidar da própria alimentação, por fatores como, omissão de refeições, alto consumo de lanches rápidos, instabilidade psicossocial, desencadeando possíveis doenças crônicas não transmissíveis nessa população. Um grupo de alimentos frequentemente consumido por uma pessoa ou população é chamado de padrão alimentar. São poucos os estudos que abordam padrões alimentares e correlacionam com o estado nutricional de universitários. Objetivo: Verificar a associação dos padrões alimentares e o estado nutricional de estudantes universitários. Metodologia: Trata-se de um estudo transversal com abordagem descritiva e analítica, realizado em uma Universidade privada em Fortaleza, Ceará. Foi realizada entrevista para coleta de dados socioeconômicos, demográficos, antropométricos e de consumo alimentar. A amostra foi composta por 150 estudantes. Resultados: Foram identificados três padrões alimentares. Mulheres mostraram maior adesão que os homens ao padrão saudável(p=0,014). A maioria dos universitários de 19 a 24 anos mostrou alta adesão ao padrão misto(p=0,012). Alunos que demonstraram excesso de peso tiveram maior adesão ao padrão misto (p=0,020). Conclusões: O padrão alimentar dos universitários possui significativa influência da idade, sexo, excesso de peso e índice de massa corporal (AU).

Introduction:Food is one of the main factors for health promotion. Academic and lifestyle situations make it difficult for university students to take care of their own food, due to factors such as omission of meals, high consumption of snacks, psychosocial instability, triggering possible chronic non-communicable diseasesin this population. A group of foods often consumed by a person or population is called a dietary pattern. There are few studies that address dietary patterns and correlate with the nutritional status of university students.Objective:To verify the association of dietary patterns and the nutritional status of university students.Methodology:This is a cross-sectional study with a descriptive and analytical approach, carried out at a private University in Fortaleza, Ceará. An interview was conducted to collect socioeconomic, demographic, anthropometric and food consumption data. The sample consisted of 150 students. Results:Three dietary patterns have been identified. Women showed greater adherence than men to the healthy pattern(p=0.014). Most university students aged 19 to 24 years old showed high adherence to the mixed pattern(p=0.012). Students who showed excess weight had greater adherence to the mixed pattern (p=0.020). Conclusions:The dietary pattern of college students has a significant influence on age, sex, overweight andbody mass index (AU).

Influence of conditional cash transfer program on prenatal care and nutrition during pregnancy: NISAMI cohort study

ABSTRACT BACKGROUND: There are few studies on the influence of a cash transfer program on nutritional outcomes from pregnancy. OBJECTIVES: To analyze how a Brazilian conditional cash transfer program (Bolsa Familia Program, BFP) was associated with changes in body mass index (BMI) and food consumption among pregnant women. DESIGN AND SETTING: Cohort study on 250 pregnant women (≥ 18 years of age) in Brazilian prenatal services. METHODS: A food frequency questionnaire was used to evaluate dietary intake. Weight was measured in each gestational trimester. Generalized estimation equations and structural equation modeling were used for statistical analyses. Correlations were analyzed using standardized coefficients (SCs). RESULTS: Women benefitting from the BFP were of greater age and had lower education. The BFP exerted a direct negative effect on the pregnant women's consumption choices regarding refined grains, regional foods, vegetable oil, sausages, salted meats and snacks (SC = -0.10) and on maternal BMI (SC = -0.12). Among the intermediate variables, we observed that the time elapsed since pregnancy and the month of prenatal onset had direct negative effects; and that the number of visits to doctors, family income and number of years of education had direct positive effects. CONCLUSIONS: Beneficiaries were less likely to increase their BMI outside of the recommended standards and had a greater tendency to receive prenatal care. Participation in the BFP had a direct negative effect on adherence to unhealthy diets.

Dietary Patterns during Pregnancy and Gestational Weight Gain: A Systematic Review / Padrões alimentares durante a gravidez e ganho de peso gestacional: Uma revisão sistemática

Abstract The present systematic review (PROSPERO: CRD42020148630) hypothesizes the association of excessive weight gain during pregnancywith dietary patterns composed of ultraprocessed foods. Thus, the objective was to investigate the association between dietary patterns after analysis and weight gain during pregnancy. The search for articles was performed in nine databases. Two reviewers selected the articles in the databases and extracted from them the data used in the review. Two scales were used to evaluate the quality of the selected studies: New Castle-Ottawa Quality Assessment for cohort-based studies and Appraisal tool for Cross-Sectional Studies (AXIS) for cross-sectional-based studies. In total, 11 studies were identified with sample size variation (n=173-5,733). Women presenting more adherence to healthy and traditional patterns (fruits, vegetables, salads, nuts, and dairy) recorded less excessive gestational weight gain (GWG). Higher intake ofmixed patterns and western patterns rich in ultraprocessed foods were associated with a higher prevalence of excessive GWG (24.48- 55.20%). Gestational dietary patterns a posteriori-derived that have presented ultraprocessed components rich in fat and sugars presented association with high GWG; healthy and traditional dietary patterns were related to better mother-child health conditions, such as adequate GWG.

Resumo A presente revisão sistemática (PROSPERO: CRD42020148630) tem como hipótese que o ganho de peso excessivo durante a gravidez está associado aos padrões alimentares compostos por alimentos ultraprocessados. Desta forma, objetivou-se investigar a associação entre o padrão alimentar a posteriori e o ganho de peso durante a gestação. A busca de artigos foi realizada em nove bases de dados. Dois revisores selecionaram os artigos nestas bases e extraíram as informações utilizadas na revisão. Duas escalas foram utilizadas para avaliar a qualidade dos estudos selecionados: Escala de Avaliação da Qualidade de New Castle-Ottawa para estudos baseados em coortes e a Ferramenta de Avaliação de Estudos Transversais (escala AXIS) para estudos transversais. No total, foram identificados 11 trabalhos com variação do tamanho amostral (n=173-5.733). As mulheres que apresentaram maior adesão aos padrões alimentares saudáveis e tradicionais (frutas, hortaliças e vegetais, nozes e laticínios) apresentarammenor ganho de peso gestacional (GPG). A maior ingestão de padrões alimentares mistos e ocidentais ricos em alimentos ultraprocessados foi associada a uma maior prevalência de GPG excessivo (24,48-55,20%). Os padrões alimentares gestacionais derivados a posteriori que apresentaram componentes ultraprocessados ricos em gordura e açúcares apresentaram associação como maior GPG; os padrões alimentares saudáveis e tradicionais foram relacionados a melhores condições de saúde maternoinfantil, como GPG adequado.

Association of dietary patterns, number of daily meals and anthropometric measures in women in age of menopause

ABSTRACT Objective: To investigate the association of dietary patterns, number of daily meals and anthropometric measures among women in age of menopause. Subjects and methods: This was a transversal study with 320 women over 50 years old from Caxias do Sul, Brazil. The outcomes were body mass index (BMI) and waist circumference (WC). Multiple linear regression was performed. Results: Three dietary patterns: regional, fruits and vegetables, and common Brazilian was identified by Principal Component Analysis. After adjustment, higher adoption of the regional dietary pattern was associated with increased BMI (β = 0.56 [CI95% = 0.03-1.08], p = 0.037) and WC (β = 1.28 [CI95% = 0.17-2,55], p = 0.047). The highest number of meals per day (>=5/day) was associated with reduced BMI (β = -1.18 [CI95% = -2.30 to -0.05], p = 0.041) and WC (β = -2.77 [CI95% = -5.41 to -0.13], p = 0.039), and a mid-afternoon snack BMI (β = -2.16 [CI95% = -3.66 to -0.65], p = 0.005) and WC (β = -5.76 [CI95% = -9.29 to -2.23], p = 0,001). The regional dietary pattern was inversely associated with have five or more meals per day (β = -0.51 [CI95% = -0.84 to -0.18], p = 0.002) and have a mid-afternoon snack (β = -0.63 [CI95% = -1.07 to -0.18], p = 0.006). The fruit and vegetables dietary pattern was positively associated with have five or more meals per day (β = 0.35 [CI95% = 0.02-0.69], p = 0.034). Conclusion: The regional dietary pattern has resulted in higher BMI and WC measures and contributes to decreased meals per day, behavior associated with higher anthropometric measures.

Variaciones en el estado nutricional, presión arterial y en los patrones dietéticos de jóvenes posterior al ingreso a la educación superior

RESUMEN El objetivo fue analizar los cambios en el estado nutricional, presión arterial y patrones dietéticos de jóvenes evaluados durante la primera semana de inducción y seis meses posterior al ingreso a la Facultad de Ciencias de la Salud de una universidad pública de Valparaíso, Chile. Estudio comparativo, con diseño longitudinal de cohorte, análisis por-protocolo. Los patrones dietéticos se determinaron mediante una Encuesta de Tendencia de Consumo Cuantificado, la evaluación antropométrica incluyó mediciones estandarizadas de peso, estatura y perímetro de cintura, la composición corporal se determinó mediante impedancia bioeléctrica, y la presión arterial con esfigmomanómetro digital. Las mediciones se realizaron al inicio y término del primer semestre de 2017 (n= 76). En ambos sexos se observó una ganancia significativa de peso corporal, IMC, masa grasa e incremento de la presión arterial sistólica, además en hombres aumentó el perímetro de cintura y la presión arterial diastólica (p<0,05). Los hombres disminuyeron significativamente el consumo de lácteos (-43,1%) y aumentaron el consumo de carnes procesadas y comida rápida (40,6%), en cambio las mujeres disminuyeron significativamente el consumo de bebidas y refrescos (-58,0%) y de alimentos con cafeína (-54,1%). No hubo cambios en el consumo de energía y macronutrientes, sin embargo, un alto porcentaje presentó un consumo deficiente de ácidos grasos poliinsaturados ω-3, fibra dietética, ciertas vitaminas y minerales, y principalmente excesivo en ácidos grasos saturados, fósforo y sodio. Se identificaron cambios negativos en el estado nutricional, presión arterial y en los patrones dietéticos posterior al ingreso a la educación superior.

ABSTRACT The objective was to analyze the changes in nutritional status, blood pressure and dietary patterns, of young people evaluated during their induction week and six months after being admitted to the Faculty of Health Sciences of a public university in Valparaiso, Chile. This was a comparative study, with a longitudinal cohort, per-protocol analysis. Anthropometric evaluation included standardized measures of weight, height and waist circumference. Body composition was determined through bioelectrical impedance, and blood pressure was measured using a digital sphygmomanometer. Dietary patterns were determined through a survey of quantified consumption trends. Measurements were taken at the beginning (n= 139) and end of the first term in 2017 (n=76). In both sexes, significant increases in body weight, BMI, fat mass and systolic blood pressure were observed. Furthermore, in men, increases in waist circumference and diastolic blood pressure (p<0.05) were observed. Men significantly decreased their dairy consumption (-43.1%) and increased their consumption of processed meats and fast-food (40.6%). Conversely, women significantly decreased their soft drink consumption (-58.0%) and caffeinated products (-54.1%). No changes in energy and macronutrient consumption were observed. A high percentage of the participants presented a deficient consumption of polyunsaturated fatty acids ω-3, dietary fiber, and certain vitamins and minerals. They also presented excessive consumption of saturated fatty acids, phosphorus and sodium. Negative changes were identified in nutritional state, blood pressure and dietary patterns when admitted in tertiary education.

Dietary patterns and sarcopenia in older adults: a cross-sectional study / 中华健康管理学杂志

Objective:Investigate the relationship between dietary patterns and sarcopenia in a Chinese elderly population.Methods:Participants in this cross-sectional study were recruited from the Tianjin Chronic Low-grade Systemic Inflammation and Health Cohort Study. The study population comprised 2 423 participants, with mean age of (67.6±5.2) years. Sarcopenia was defined based on the guidelines of the Asian Working Group for Sarcopenia. Three dietary patterns were derived by factor analysis: fruit and sweet pattern, traditional oriental pattern, and animal food pattern. The association between quartile categories of dietary pattern scores and the presence of sarcopenia was analyzed using multiple logistic regression models. Odds ratios ( OR) and 95% confidence interval ( CI) were calculated. Results:The prevalence of sarcopenia was 16.1%. After adjusting for confounding factors, compared with the lowest quartile, the adjusted OR ( 95%CI) of sarcopenia for the highest quintile of Fruit and sweet pattern score, Traditional oriental pattern score and Animal food pattern score were 1.06 (0.74, 1.50), 0.54 (0.34, 0.86), and 0.50 (0.33, 0.74), ( P for trend were 0.87,<0.01, and<0.001), respectively. Conclusions:The current study found that the traditional oriental pattern and animal food pattern has a protective relation for sarcopenia in elderly adults, which suggests its potential to attenuate or prevent the progression of sarcopenia.

Dietary patterns of Brazilian adults with neurofibromatosis type 1 / Patrones dietéticos de adultos brasileños con neurofibromatosis tipo 1

ABSTRACT Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disease characterized by multisystem involvement such as bone, muscle, endocrine, ophthalmologic, cardiovascular, central and peripheral nervous system, cognitive capacity, voice, and oral motor disorders. Nutritional studies in individuals with NF1 have been performed recently. While a previous study showed an inadequate nutrient intake in patients with NF1, the dietary patterns of this population have not yet been widely studied. This study aimed to characterize dietary patterns in Brazilian adults with NF1. Sixty NF1 individuals (51.7% women), ≥18 years of age underwent nutritional assessment including laboratory analysis, anthropometrics, and eating habits recorded on a food frequency questionnaire. Cluster analysis was used to distinguish between dietary patterns. Hypothesis tests were used to compare data. Two groups with distinct patterns were identified, "Healthy" (46.7%) and "Western" (53.3%). These groups were similar in most of the socioeconomic, anthropometric, demographic and laboratory parameters evaluated. However, the upper-arm total area and upper-arm muscle area (UAMA) were lower in the Western group than those in the Healthy group [59.8 (25.7) cm2 versus 65.6 (28.3) cm2, P=0.049; 35.6±12.4 cm2 versus 43.8±15.0 cm2, P=0.024, respectively]. In this study, most individuals with NF1 had a Western dietary pattern and this group showed a lower UAMA, which may indicate a potential contribution, even in part, of diet in the muscle phenotype in this population. This association between diet and muscle in NF1 individuals requires investigation in further studies.

RESUMEN La neurofibromatosis tipo 1 (NF1) es una enfermedad genética autosómica dominante caracterizada por la afectación multisistémica, alterando los sistemas óseo, muscular, endocrino, oftálmico, cardiovascular, nervioso central y periférico así como las capacidades cognitivas. Un estudio previo señaló una ingesta inadecuada de nutrientes en pacientes con NF1, pero los patrones dietéticos de esta población aún no han sido estudiados ampliamente. El objetivo de este est udio es caracterizar los patrones dietéticos en brasileños con NF1. Sesenta individuos con NF1 (51,7% mujeres) ≥18 años se sometieron a una evaluación nutricional que incluyeron análisis de laboratorio, antropometría y hábitos alimentarios registrados en un cuestionario de frecuencia alimentaria. El análisis de conglomerados se utilizó para distinguir los patrones dietéticos; las pruebas de hipótesis para comparar datos. Se identificaron dos grupos con patrones distintos, denominados Saludables (46,7%) y Occidentales (53,3%). Estos grupos fueron similares en la mayoría de los parámetros socioeconómicos, antropométricos, demográficos y de laboratorio evaluados. Sin embargo, las áreas total braquial (ATB) y muscular braquial (AMB) fueron menores en el grupo occidental que en el grupo sano [59,8 (25,7) cm2 y 65,6 (28,3) cm2, P= 0,049; 35,6 ± 12,4 cm2 y 43,8 ± 15,0 cm2, P= 0,024, respectivamente]. En este estudio, la mayoría de las personas con NF1 habían consumido un patrón dietético occidental y este grupo presentó un AMB menor, lo que puede indicar una contribución potencial, incluso en parte, de la dieta en el fenotipo muscular en esta población. Esta asociación entre dieta y músculo en personas con NF1 requiere investigaciones en estudios adicionales.

Relationship between dietary patterns and sleep disorders among health screening population in Changsha / 中南大学学报(医学版)

OBJECTIVES@#Sleep disorders directly affect health-related quality of life, so it is of great significance to investigate the risk factors of sleep disorders and to actively intervene. This study aims to investigate the relationship between dietary patterns and associated factors and sleep disorders among the health screening populations in Changsha.@*METHODS@#A cross-sectional study was carried out in 86 073 subjects aged 18-70 years old who underwent the health screening. The association between dietary patterns and sleep disorders was analyzed. The associated factors for sleep disorders were identified via by principal component analysis and classification tree model.@*RESULTS@#The overall prevalence of reporting sleep disorders was 18.64%. Four major dietary patterns (healthy, snacks, whole-grain, and fried food patterns) were identified. In logistic regression, snacks and fried food patterns had higher risk of sleep disorders. The whole-grain pattern was a protective factor for sleep disorders. Nine associated factors including age, susceptibility to anxiety, snacking parterns, feelings of depression, chronic pain, physical activity, educational level, gender, and weight, and 9 groups at high risk for sleep disorders were identified by classification tree model.@*CONCLUSIONS@#Sleep disorders are prevalent in the health screening population of Changsha. There is a close association between snacks dietary patterns and sleep disorders. It is necessary to promote healthy and reasonable diet, and keep good lifestyle for the prevention and control of sleep disorders. Health management after physical examination should take different health interventions for high-risk groups with different characteristics of sleep disorders.

How to reduce the risk of cervical cancer has become the focus of the efforts of researchers in this field. Dietary patterns are analyzed based on the overall dietary status, and at the same time the interaction between nutrients and food is taken into consideration. Accumulating evidence suggests that dietary patterns play an important role in the prevention of cervical cancer. This review summarizes the relationship between different dietary patterns and the incidence of cervical cancer, and aims to provide a basis for more in-depth research in the future.

Association between dietary intake and bone density among female Students at Imam Abdulrahman Bin Faisal University, Saudi Arabia

Background: Recently, new studies have shown that the prevalence of osteoporosis and related fractures has been increased among young females. This study aimed at finding out the association between dietary intake and bone mineral density (BMD) among university Saudi female students at Imam Abdulrahman Bin Faisal University.Methods: A cross sectional study was carried out on 104 females’ students aged 18-24 years taken randomly from Rakkah campus. Dual X-ray absorptiometry was used to evaluate BMD and body composition. A complete and valid questionnaire was used to collect the required information about socio-economic status, lifestyle, body measurements, health history data, and food habits as well as food frequency questionnaire was also used. The results were statically analyzed (SPSS, 2015 V, 23) and descriptive statistics Chi-square test and independent samples t- test were used for the statistical analysis.Results: The results demonstrated that the majority (65%) of students have normal body mass index (18.5-24.9 kg/m2), 58% normal BMD (>-1.0 SD) and 42% have low BMD. Among the low BMD students, 4% having osteoporosis (<-2.5 SD). In the present study, 36.5%, 30.8%, 37.5% and 36.5 % of student with high BMD consumed full fat dairy products, milk, yogurt, laben, cheese, respectively, compared with 21.2%, 19.2%, 245, 29.8% of students with low BMD.Conclusions: Higher intakes in dairy products were associated with students’ bone health. Therefore, students should be more aware of their bone health and increase their knowledge regarding protective dietary foods for bone development.

Padrões alimentares de trabalhadores bancários e sua associação com fatores socioeconômicos, comportamentais e laborais / Dietary patterns of bank employees and their association with socioeconomic, behavioral and labor factors

Resumo O presente artigo busca avaliar o consumo alimentar de trabalhadores bancários e sua associação com fatores socioeconômicos, comportamentais e laborais. Trata-se de um estudo transversal com 515 bancários. Para avaliar o consumo alimentar foi utilizado Questionário de Frequência Alimentar semiquantitativo, empregando-se a análise de componentes principais com rotação varimax para determinação dos padrões alimentares. Foram identificados três padrões alimentares: "hortaliças, frutas, cereais e tubérculos", "doces e petiscos" e "tradicional e proteico". Constatou-se que os indivíduos que não consumiam adoçantes possuíam mais chances de aderirem ao padrão "hortaliças, frutas, cereais e tubérculos" e menos chances de aderirem aos padrões "doces e petiscos" e "tradicional e proteico". Os bancários, que raramente comiam em restaurante, tinham três vezes mais adesão ao "doces e petiscos". Entretanto, os que consumiam temperos industrializados e os que relataram receber baixo apoio social tinham, respectivamente, 2,3 e 1,5 vezes mais chances de aderirem ao "tradicional e proteico". Conclui-se que o consumo alimentar de bancários não está relacionado às condições sociodemográficas destes indivíduos, estando associado a estes padrões alimentares, o comportamento e a percepção do apoio social recebido.

Abstract This paper aimed to evaluate food consumption of bank employees and its association with socioeconomic, behavioral and labor factors. This is a cross-sectional study with 515 bank employees. To evaluate food consumption, a semi-quantitative food frequency questionnaire was used. The analysis of main components with Varimax rotation was used to determine the dietary patterns. Three dietary patterns were identified: "vegetables, fruits, cereals and tubers", "sweets and snacks" and "traditional and protein". We found that individuals who did not consume sweeteners were more likely to adhere to the "vegetables, fruits, cereals and tubers" pattern and were less likely to adhere to the "sweets and snacks" and "traditional and protein" patterns. Bank employees who rarely ate in restaurants were three times more likely to adhere to the "sweets and snacks" pattern. However, those who used to consume industrialized seasoning and those who reported receiving low social support were, respectively, 2.3 and 1.5 times more likely to adhere to the "traditional and protein" pattern. We can conclude that food consumption of bank employees is not related to the sociodemographic conditions of these individuals, and behavior and perception of social support received is associated with these dietary patterns.

Associations between dietary patterns and metabolic syndrome in adolescents / Asociación entre patrones de alimentación y síndrome metabólico en adolescentes

Abstract: Objective: Evaluate association of dietary patterns with metabolic syndrome (MetS) and metabolic markers. Materials and methods: 654 adolescents from Guadalajara, Jalisco, participated in a cross-sectional study. Diet was evaluated using a food frequency questionnaire; 24 food groups were integrated, and dietary patterns were derived using cluster analysis. MetS was defined according to International Diabetes Federation (IDF), Cook and colleagues, Ford and colleagues, and de Ferranti and colleagues criteria. Results: Dietary patterns identified were: "DP1", "DP2", and "DP3". Among males, "DP3" was associated with MetS (Cook and collaborators) (OR, 12.14; 95%CI, 1.66-89.05), hypertriglyceridemia (OR, 3.89; 95%CI, 1.01-15.07), and insulin resistance (OR, 6.66; 95%CI, 1.12-39.70). "DP2" was associated with abdominal obesity (OR, 5.11; 95%CI, 1.57-16.66). Conclusions: "DP3" entertained a greater risk of MetS, hypertriglyceridemia, and insulin resistance, while "DP2" possessed a greater risk of abdominal obesity among adolescent males.

Resumen: Objetivo: Evaluar la asociación de patrones dietarios (PD) con síndrome metabólico (SM) y marcadores metabólicos. Material y métodos: Estudio transversal con 654 adolescentes. Dieta evaluada con el cuestionario "frecuencia de consumos de alimentos"; se identificaron 24 grupos de alimentos, para obtener PD mediante análisis de conglomerados. SM se definió según los criterios: Federación de Diabetes Internacional (IDF), Cook y colaboradores, Ford y colaboradores y Ferranti y colaboradores.

El patrón "PD2" se asoció con obesidad abdominal (RM, 5.11; IC95%, 1.57-16.66). Conclusiones: El patrón "PD3" aumenta el riesgo de SM, hipertrigliceridemia y resistencia a insulina y el "PD2" el riesgo de obesidad abdominal en adolescentes hombres.

Obesidade abdominal e padrões alimentares em mulheres trabalhadoras de turnos / Abdominal obesity and dietary patterns in female shift workers

Resumo Objetivou-se identificar os padrões alimentares e a associação destes com a obesidade abdominal em mulheres trabalhadoras de turnos no sul do Brasil. Para isso, realizou-se um estudo de caso-controle não pareado, incluindo um total de 541 mulheres de 18 a 53 anos de idade (215 casos; 326 controles). A presença de obesidade abdominal foi verificada pela aferição da circunferência da cintura ≥ 88 centímetros e os padrões alimentares foram obtidos por meio da análise de componentes principais de 53 itens. Os padrões foram classificados com base nos alimentos de maior carga fatorial e características nutricionais. A associação entre obesidade abdominal e os padrões foi verificada por meio de regressão logística não condicional. Três padrões alimentares foram identificados: "gordura animal/calorias", "lanches/fast-food" e "frutas/verduras". Após análise ajustada, os casos apresentaram uma maior chance de adesão ao padrão "frutas/verduras" (OR = 2,26; IC95%:1,30-3,93) e uma menor chance de adesão ao padrão "lanches/fast-food" (OR = 0,60; IC95%:0,36-1,01). Assim, identificou-se três padrões alimentares entre as trabalhadoras de turnos e verificou-se uma melhora na alimentação naquelas com obesidade abdominal, representando uma possível alteração de hábitos alimentares após sua ocorrência.

Abstract The scope of this study was to identify dietary patterns and their association with abdominal obesity in female shift workers in southern Brazil. A non-matched case-control study was conducted, including a total of 541 women aged between 18 and 53 years old (215 cases; 326 controls). The presence of abdominal obesity was assessed by measuring waist circumference ≥ 88 cm and dietary patterns were obtained by principal component analysis of 53 food items. The name of dietary patterns was assigned based on higher load factor and nutritional characteristics of foods. The association between abdominal obesity and dietary patterns was obtained by non-conditional logistic regression. Three dietary patterns were identified: "animal fat/calories," "snacks/fast-food" and "fruits/vegetables." After adjusted analysis, the cases presented a greater chance of adherence to the "fruits/vegetables" dietary pattern (OR = 2.26; 95% CI: 1.30 to 3.93) and a lower chance of adherence to the "snacks/fast food" pattern (OR = 0.60; 95% CI: 0.36 to 1.01). In conclusion, this study identified three dietary patterns in female shift workers, and there was an improvement in nutrition in workers with abdominal obesity, representing a possible change in eating habits after their occurrence.

Socioeconomic inequality in dietary intake begins before 24 months in Brazilian children

ABSTRACT OBJECTIVE: To assess dietary patterns by socioeconomic gradient of Brazilian infants and young children in 2006 and 2013. METHODS: Data from the National Demographic Survey (2006) and the National Health Survey (2013) were used. Food intake were described by wealth index, age range and survey year. Dietary patterns were defined by principal component analysis. Association of wealth index and dietary patterns were modelled using linear regression. RESULTS: Breast milk intake was higher for poor infants and young children, while fresh food intake (fruits, vegetables, meats, beans) was higher for the richer ones in 2006 and 2013. Biscuits and sweetened beverages were more consumed by rich infants and young children in 2006 and by poor and rich children in 2013. Three dietary patterns (DP1, DP2, and DP3) were identified in 2006 and four in 2013 (DP1, DP2, DP3, and DP4). DP1 was composed mainly of fresh foods, and it was positively associated with the wealth index for infants and young children in both years. DP2 was composed of biscuits, cookies and sweetened beverages, and it was positively associated with the wealth index for young children in 2006 and for poor and rich infants and young children in 2013. DP3 was composed of milk, water and porridge in both years, and it was not associated with the wealth index. DP4 was composed of breast milk and porridge, and it was negatively associated with the wealth index. CONCLUSIONS: DP1 is a characteristic pattern for richer infants and young children since 2006, while DP2 is a characteristic pattern for all infants and young children in 2013, regardless of wealth index. Dietary inequality between the poor and the rich seems to begin in childhood.

Associations between the dietary patterns of pregnant Malaysian women and ethnicity, education, and early pregnancy waist circumference: A prospective cohort study

BACKGROUND/OBJECTIVES: Little is known about the dietary patterns (DPs) of women during pregnancy. The present study aimed to identify the DPs of pregnant Malaysian women and their associations with socio-demographic, obstetric, and anthropometric characteristics. SUBJECTS AND METHODS: This prospective cohort study included 737 participants enrolled in Seremban Cohort Study between 2013 and 2015. Food consumption was assessed using a validated 126-food item semi-quantitative food frequency questionnaire (SFFQ) at four time-points, namely, pre-pregnancy and at each trimester (first, second, and third). Principal component analysis (PCA) was used to identify DPs. RESULTS: Three DPs were identified at each time point and designated DP 1–3 (pre-pregnancy), DP 4–6 (first trimester), DP 7–9 (second trimester) and DP 10–12 (third trimester). DP 1, 4, and 7 appeared to be more prudent diets, characterized by higher intakes of nuts, seeds & legumes, green leafy vegetables, other vegetables, eggs, fruits, and milk & dairy products. DP 2, 5, 8, and 11 had greater loadings of condiments & spices, sugar, spreads & creamer, though DP 2 had additional sweet foods, DP 5 and 8 had additional oils & fats, and DP 11 had additional tea & coffee, respectively. DP 3 and 6 were characterized by high protein (poultry, meat, processed, dairy, eggs, and fish), sugars (mainly as beverages and sweet foods), and energy (bread, cereal & cereal products, rice, noodles & pasta) intakes. DP 9 had additional fruits. However, DP 12 had greater loadings of energy foods (bread, cereal & cereal products, rice, noodles & pasta), sugars (mainly as beverages, and sweet foods), and good protein sources (eggs, nuts, seeds & legumes). Malays were more likely to have lower adherence (LA) for DP 1 and 10 than non-Malays. DP 2, 8, and 11 were more prevalent among Malays than non-Malays. Women with a higher education were more likely to have LA for DP 10, and women with a greater waist circumference at first prenatal visit were more likely to show LA for DP 11. CONCLUSIONS: DPs observed in the present study were substantially different from those reported in Western populations. Information concerning associations between ethnicity, waist circumference and education with specific DPs before and throughout pregnancy could facilitate efforts to promote healthy dietary behavior and the overall health and well-being of pregnant women.
