Perinatal and parental determinants of childhood overweight in 6-12 years old children

Introduction & aims: The identification of determinants of childhood overweight is crucial to early diagnosis and prevention. The aim of this study was to assess perinatal and parental related risk factors concerning children for having excessive body weight. Methods: Cross-sectional study involving 3,101 children participating in the programme “Alimenta su salud” conducted in Castilla-La Mancha (Spain). Anthropometric and sociodemographic data were obtained from a general questionnaire. Analysed factors as potential predictors of childhood overweight were sex, age, birth weight, infant feeding, number of siblings, as well as parental marital status, educational level and obesity. Prevalence of overweight stratified by potential determinants was assessed. Univariate and multivariate logistic regression analyses were used to examine the associations between variables and the likelihood of being overweight. Results: The overweight prevalence (including obesity) was 30.3% in boys and 28.3% in girls, according to the IOTF criteria. Higher rates in younger subjects and some gender differences were observed. Parental obesity was the most important predictive variable for childhood overweight in both sexes and birth weight over 3,500 g in girls (OR 1.8, 95% CI 1.3-2.3). Having one or more siblings (OR 0.7, 95% CI 0.5-0.9) and higher paternal education (OR 0.8, 95% CI 0.6-0.9) in boys, and older age in girls (OR 0.7, 95% CI 0.5-.09), resulted protective factors against childhood overweight. No independent effects of marital status, maternal education and infant feeding patterns on childhood excess weight were identified. Conclusions: Perinatal and parental factors could contribute to predict the risk of being overweight/obese in children aged 6 to 12 years, which should be considered when formulating obesity prevention and intervention strategies, stressing the importance of targeting obese parents with young children

Parity implications for anthropometrical variables, lifestyle behaviors and dietary habits in pregnant women

Background. Maintaining an adequate health status and appropriate lifestyles during pregnancy is of great importance to prevent adverse outcomes for both mother and baby. The present study aimed to assess the nutritional status, socio-demographic features, lifestyle behaviors and dietary habits of pregnant women in Spain, and to identify the influence of parity on these profiles. Methods. This cross-sectional study included pregnant women from regions all over Spain. The information was collected through a 40 item questionnaire, previously validated, by community health professionals. Results. The 5,087 pregnant women analyzed had an average age of 31.9 years with an adequate nutritional status. The distribution of the sample was 56% nulliparous and 44% multiparous. The nulliparous reported a better self-perceived health status and nutritional balance, and a lower incidence of gestational diabetes mellitus. However, the multiparous showed healthier lifestyle habits (lower rates of smoking and alcohol consumption) and more physically active patterns. Regarding diet, nulliparous pregnant women consumed more dairy products, fresh fruit and nuts, and less bread, rice/pasta/potatoes, meat, sausage and buns/pastries than multiparous pregnant women. Conclusions. Differences between analyzed patterns were observed in anthropometrical variables, lifestyle behaviors and dietary habits, which may require different nutritional messages to nulliparous as compared to multiparous from a public health point of view.Fundamento. Durante el embarazo, el mantenimiento de un adecuado estado de salud y estilos de vida, es de gran importancia para prevenir resultados adversos tanto para la madre como para el bebé. El presente estudio tuvo como objetivos evaluar el estado nutricional, características sociodemográficas, estilos de vida y hábitos alimentarios de mujeres embarazadas en España, e identificar la influencia de la paridad sobre estos perfiles. Material y método. Este estudio transversal incluyó mujeres embarazadas de todas las comunidades autónomas de España. La información se recogió a través de un cuestionario de 40 preguntas, previamente validado, por profesionales de la salud comunitarios. Resultados. Las 5.087 mujeres embarazadas presentaron una edad media de 31,9 años y un adecuado estado nutricional. De la muestra un 56% fueron nulíparas y un 44% multíparas. Las mujeres nulíparas declararon mejor autopercepción de su estado de salud y estado nutricional, y menor incidencia de diabetes mellitus gestacional. Sin embargo, las mujeres multíparas mostraron estilos de vida más saludables (tasas de consumo de tabaco y alcohol más bajas) y un patrón de actividad física más activo. En cuanto a la dieta, las nulíparas consumieron más lácteos, fruta fresca y frutos secos, y menos pan, arroz/pasta/patatas, carne, embutidos y bollos/pasteles que las multíparas. Conclusiones. Se observaron diferencias entre los grupos analizados en cuanto a variables antropométricas, estilos de vida y hábitos alimentarios, que pueden requerir distintos mensajes nutricionales para mujeres nulíparas y multíparas, desde un punto de vista de Salud Pública

Dietary patterns and total mortality in a Mediterranean cohort: the SUN project

BACKGROUND: Different dietary patterns have been associated with several health outcomes, including morbidity and mortality. There is little evidence on the association between empirically derived dietary patterns and all-cause mortality in Southern European populations. OBJECTIVE: The aim of our study was to prospectively evaluate the association between an empirically derived dietary pattern and all-cause mortality. DESIGN: The Seguimiento Universidad de Navarra (SUN) Project is an ongoing, multipurpose, prospective and dynamic Spanish cohort. PARTICIPANTS/SETTING: Participants were a prospective cohort of 16,008 middle-aged Spanish adults. All of them were university graduates (alumni) (59.6% women, mean age 38 years). Usual diet was assessed at baseline with a validated semiquantitative food frequency questionnaire. MAIN OUTCOME MEASURES: Deaths were confirmed by review of medical records and of the National Death Index. STATISTICAL ANALYSIS: Dietary patterns were ascertained through a factor (principal component) analysis based on 30 predefined food groups. Participants were classified according to tertiles of adherence to the three main dietary patterns identified with factor analysis. Cox regression models were fitted to estimate multivariable-adjusted hazard ratios and 95% CIs for mortality. RESULTS: Three major dietary patterns were identified. They were labelled Western dietary pattern (rich in red and processed meat, potatoes, and fast food), Mediterranean dietary pattern (rich in vegetables, fish and seafood, fruits, and olive oil), and alcoholic beverages dietary pattern. During follow-up, 148 deaths were reported (mean age at death 54.5 years). After adjustment for potential confounders, the lowest risk of all-cause mortality was found in the tertile of highest adherence to the Mediterranean dietary pattern (adjusted hazard ratio for third vs first tertile 0.53, 95% CI 0.34 to 0.84) (P for trend <0.01). The Western dietary pattern and alcoholic beverages dietary pattern showed no significant association with mortality. CONCLUSIONS: Greater adherence to an empirically derived dietary pattern approaching the traditional Mediterranean diet was associated with a reduction in the risk of all-cause mortality among middle-aged Mediterranean adults

Associations between overall, healthful, and unhealthful low-fat dietary patterns and breast cancer risk in a Mediterranean cohort: The SUN project

Objectives: Dietary patterns may have a greater influence on human health than individual foods or nutrients, and they are also of substantial interest in the field of breast cancer prevention. Beyond the adequate balance of macronutrients, evidence indicates that the quality of macronutrient sources may play an important role in health outcomes. We sought to examine the relationship between healthful and unhealthful low-fat dietary patterns in relation to breast cancer. Methods: We used observational data from a Mediterranean cohort study (the Seguimiento Universidad de Navarra project). We prospectively followed 10 930 middle-aged women initially free of breast cancer during a median follow-up of 12.1 y. We calculated an overall, an unhealthful, and a healthful low-fat diet score, based on a previously validated 136-item food frequency questionnaire and grouped participants into ter- tiles. Incident breast cancer—overall and stratified by menopausal status—was the primary outcome. It was self-reported by participants and confirmed based on medical reports or consultation of the National Death Index. We used multivariable Cox regression models adjusted for potential confounders. Results: During 123 297 person-years of follow-up, 150 cases of incident breast cancer were confirmed. No signifi- cant associations were observed for overall or premenopausal breast cancer. For postmenopausal women, we observed a significant association for moderate adherence to the unhealthful low-fat dietary score and postmeno- pausal breast cancer (comparing tertile 2 to tertile 1; hazard ratio = 2.18; 95% confidence interval, 1.15 4.13). Conclusions: In conclusion, no clear associations were observed, although more research is needed to address the association between an unhealthful dietary pattern and postmenopausal breast cancer risk

Are there anthropometric differences between children with autism and healthy children?

Anthropometric development and growth were assessed in 2 groups of 6- to 9-year-olds: children with autism spectrum disorders and typically developing children. In a case-control study conducted in Valencia, Spain, we compared the body mass index (kg/m(2)) of 40 children with autism spectrum disorders (cases) and 113 typically developing children (controls) from the same area of residence. The sex- and age-adjusted odds ratios for being underweight in cases was 2.41 compared to controls. Furthermore, the body mass index distribution of the cases was significantly offset to lower values with respect to that of the controls (P = .024). In particular, 20% of the cases had a body mass index below the fifth percentile versus just 8.85% of the controls. Our data suggest that the anthropometric development of children with autism spectrum disorders should be monitored as part of routine care

Influence of parental healthy-eating attitudes and nutritional knowledge on nutritional adequacy and diet quality among preschoolers: the SENDO project

Parental nutrition knowledge and attitudes play a fundamental role in their children's food knowledge. However, little is known about their influence on their children's diet quality and micronutrient intake. Thus, we aimed to assess the association of parental nutrition knowledge and healthy-eating attitudes with their children's adherence to the Mediterranean dietary pattern and micronutrient adequacy. Parental healthy-eating attitudes and knowledge of the quality of their child's diet as well as anthropometric, lifestyle, and nutrient intake characteristics were recorded with a basal questionnaire that included a 140-item-food frequency-questionnaire. A total of 287 pre-school children were included in the analyses. Intake adequacy was defined using the Estimated Average Requirements (EAR) cut-off point method. We developed a parental nutrition knowledge and healthy-eating attitudes scores and evaluated whether they were independently associated with 1) children's inadequate intake (probability of failing to meet 3 EAR) of micronutrients, using logistic regression analyses, and 2) children's diet quality (adherence to the Mediterranean Diet according to a Mediterranean Diet Quality Index for children and adolescents, the KIDMED index), using multiple linear regression models. A higher score in the parental healthy-eating attitudes score was associated with lower risk of failing to meet 3 EAR compared with the reference category (odds ratio (OR): 0.3; 95% confidence interval (CI) 0.12-0.95; p for trend: 0.037) and a higher adherence to the Mediterranean diet in the most adjusted model ( coefficient: 0.34; 95% CI 0.01-0.67; p for trend: 0.045). Our results suggest a positive association of parental healthy-eating attitudes with nutritional adequacy and diet quality in a sample of Spanish preschoolers. Public health strategies should focus on encouraging parental healthy-eating attitudes rather than simply educating parents on what to feed their children, recognizing the important influence of parental behavior on children's practices

Consumo de jamón curado e incidencia de eventos cardiovasculares, hipertensión arterial o ganancia de peso

Fundamento y objetivo: El jamón curado es uno de los alimentos característicos de la dieta mediterránea española. Sin embargo, no existe ningún estudio epidemiológico prospectivo que haya valorado sus efectos sobre la salud humana. Nuestro objetivo fue evaluar la asociación entre el consumo de jamón curado y la incidencia de hipertensión arterial, enfermedad cardiovascular y/o ganancia de peso. Sujetos y método: En una cohorte epidemiológica prospectiva y dinámica de 13.293 graduados universitarios (Proyecto SUN) se analizó la incidencia de enfermedad cardiovascular, hipertensión arterial y la ganancia de peso a lo largo de un seguimiento máximo de 6 años. Se ajustaron modelos de regresión de Cox para estimar hazard ratios (riesgos relativos [RR]) tras ajustar por posibles factores de confusión. Resultados: El consumo de jamón en los niveles más altos (> 4 raciones/semana) no presentaba asociación con la incidencia de eventos cardiovasculares (RR=1,02; [IC 95%: 0,44-2,39]), tras ajustar por edad, sexo, ingesta energética total y patrón dietético, en comparación con los consumos inferiores a una vez por semana. Al repetir esta comparación para la hipertensión, y tras ajustar por edad, sexo, ingesta energética total e índice de masa corporal, se encontró un RR = 0.74 (IC 95%: 0.55-1.01). En la comparación del cambio de peso medio anual entre estas mismas categorías extremas de consumo (=4 raciones) se encontró una diferencia no significativa de 0,033 kg (IC 95%: -0,041 a +0,107) en la ganancia media de peso al año tras ajustar por sexo, edad, tabaco, actividad física e índice de masa corporal inicial. Conclusiones: Los resultados de esta cohorte no proporcionan evidencia de que el consumo de jamón curado se asocie a mayor riesgo cardiovascular, de hipertensión arterial o de ganancia de peso.Background and objective: Cured ham is a characteristic food in Spanish Mediterranean diet. However, no prospective epidemiologic study assessing its effects on human health is available. Our aim was to assess the association between the consumption of cured ham and cardiovascular disease, hypertension or weight gain. Subjects and Method: In a prospective and dynamic epidemiologic cohort composed exclusively of university graduates (the SUN Project, n=13,293), we analyzed the incidence of cardiovascular disease, hypertension or average yearly weight gain after a maximum follow-up of 6 years. Cox (proportional hazards) regression models were fitted to estimate hazard ratios (relative risks [RR]) after adjusting for potential confounding. Results: No association was found between higher levels of consumption of cured ham (> 4 servings/week) and the incidence of cardiovascular disease (RR=1.02; [95%CI]: 0.44-2.39), in analyses adjusted for age, sex, total energy intake and dietary pattern, compared to the consumption of less than one serving a week. When we repeated this comparison for the incidence of hypertension, and adjusting for age, sex, total energy intake and body mass index, the RR was 0.74 (95% CI: 0.55-1.01). In the comparison of average yearly weight gain between these extreme categories of cured ham consumption (=4 servings/week) a non-significant difference of 0.033 kg (95% CI: -0.041 to 0.107) was found after adjusting for sex, age, smoking, physical activity, and baseline body mass index. Conclusions: The results of this cohort study do not support any association between the consumption of cured ham and a higher risk of cardiovascular disease, hypertension or weight gain

Improved diet quality and nutrient adequacy in children and adolescents with abdominal obesity after a lifestyle intervention

High rates of childhood obesity require integral treatment with lifestyle modifications that achieve weight loss. We evaluated a lifestyle intervention on nutrient adequacy and diet quality in children and adolescents with abdominal obesity. A randomized controlled trial was performed on 107 participants, assigned either to a usual care group or to an intensive care group that followed a moderate hypocaloric Mediterranean diet and received nutritional education. Intake adequacy was evaluated using Dietary Reference Intakes and diet quality through the Diet Quality Index for Adolescents (DQI-A), the Healthy Lifestyle Diet-Index (HLD-I) and the Mediterranean Diet Quality Index (KIDMED). Both groups achieved a significant reduction in BMI standard deviation score (BMI-SDS), glucose and total cholesterol levels. Intake of Calcium, Iodine and vitamin D were higher in the intensive care group, with enhanced compliance with recommendations. Higher dietary scores were associated with lower micronutrient inadequacy. DQI-A and HLD-I were significantly higher in the intensive care group vs. usual care group after the treatment. In conclusion, we observed that an intensive lifestyle intervention was able to reduce BMI-SDS in children with abdominal obesity. Furthermore, participants significantly improved dietary indices getting closer to the nutritional recommendations. Therefore, these diet quality indices could be a valid indicator to evaluate micronutrient adequacy.High rates of childhood obesity require integral treatment with lifestyle modifications that achieve weight loss.

Egg consumption and dyslipidemia in a Mediterranean cohort

Introduction and objectives: Our aim was to prospectively evaluate the association between egg consumption and dyslipidemia in a Mediterranean cohort. Methods: We followed-up 13,104 Spanish university graduates for a mean period of 8 years. Dietary habits at baseline were assessed using a validated semi-quantitative 136-item food-frequency questionnaire. Self-reported blood concentrations of total cholesterol, high-density lipoproteins cholesterol (HDL-c) and triglycerides were evaluated according to categories of egg consumption after 6 and 8 years of follow-up. We also assessed the association between baseline egg consumption and the incidence of hypercholesterolemia, low HDL-c concentrations and hypertriglyceridemia during follow-up. Results: We observed a significant inverse association for intermediate levels of egg consumption (2 to 4 eggs/week vs. less than 1 egg/week) and hypertriglyceridemia with OR = 0.71 (95% confidence interval [CI]: 0.54 to 0.93, p < 0.05) in the multivariable-adjusted model. Using HDL-c values after 8-year follow-up, we found an association between higher egg consumption and lower HDL-c levels (p for trend = 0.02) with an adjusted difference of –4.01 mg/dl (-7.42 to -0.61) for > 4 vs. < 1 egg/week. Lower means of triglycerides were found in each of the three upper categories of egg consumption compared to the lowest category (< 1 egg/week) with significant results for some of these categories both after 6 and 8 year follow-up. Conclusions: Our data do not support that higher egg consumption was associated with abnormal blood levels of total cholesterol or triglycerides; an inverse association with HDL-c as a quantitative variable was found only in one of our analyses.Introducción y objetivos: evaluar prospectivamente la asociación entre el consumo de huevo y el riesgo de dislipidemia en una cohorte mediterránea. Métodos: se siguieron 13.104 graduados universitarios españoles durante un periodo medio de 8 años. La dieta se evaluó al inicio utilizando un cuestionario semicuantitativo de frecuencia de consumo de alimentos repetidamente validado. Las concentraciones sanguíneas de colesterol total, lipoproteínas de alta densidad (HDL-c) y triglicéridos autorreferidas fueron evaluadas según categorías de consumo de huevo tras 6 y 8 años de seguimiento. También se evaluó la asociación entre el consumo basal de huevo y la incidencia de hipercolesterolemia, concentraciones bajas de HDL-c e hipertrigliceridemia durante el seguimiento. Resultados: se observó una asociación entre los niveles intermedios de consumo de huevo (2-4 unidades/semana frente a < 1 unidad/semana) y menor riesgo de hipertrigliceridemia con OR = 0,71 (intervalo de confianza del 95% [IC]: 0,54 a 0,93, p < 0,05) en el modelo más ajustado. Tras 8 años de seguimiento, encontramos una asociación entre un mayor consumo de huevo y menores niveles de HDL-c (p tendencia lineal = 0,02) con una diferencia ajustada de -4,01 mg/dl (-7,42 a -0,61) para > 4 vs. < 1 unidad/semana. Se encontraron menores concentraciones de triglicéridos en las tres categorías superiores de consumo de huevo en comparación con la inferior con resultados significativos para algunas de estas categorías después de 6 y 8 años de seguimiento. Conclusiones: un mayor consumo de huevo no se asoció con niveles anormales de colesterol total o triglicéridos; se encontró una asociación inversa con HDL-c como variable cuantitativa solo en uno de nuestros análisis
