Short-Chain Fatty Acid Reference Ranges in Pregnant Women from a Mediterranean Region of Northern Spain: ECLIPSES Study.

Maternal short-chain fatty acids (SCFAs) play a critical role in fetal development and metabolic programming. However, an important gap in the analysis of such relationships is the lack of reference values in pregnant women. Therefore, we establish serum SCFA percentile reference ranges both early and later in pregnancy in a population from a Mediterranean region of Northern Spain. A population-based follow-up study involving 455 healthy pregnant women (mean age 30.6 ± 5.0 years) from the ECLIPSES study is conducted. Sociodemographic, obstetric, anthropometric, lifestyle, dietary variables and blood samples were collected in the first and third trimesters. Serum SCFA concentrations were measured by LC-MS/MS. The 2.5/97.5 percentiles of the reference interval for serum acetic, propionic, isobutyric, and butyric acids were 16.4/103.8 µmol/L, 2.1/5.8 µmol/L, 0.16/1.01 µmol/L and 0.32/1.67 µmol/L in the first trimester of pregnancy, respectively. In the third trimester, butyrate levels increased with most of the maternal factors and categories studied, while acetic acid and isobutyric acid decreased only in some maternal categories. Propionic acid was not affected by maternal factors. Reference ranges did not vary with maternal age, body weight, social class or diet, but decreased with smoking, high physical activity, low BMI and primiparity. This study establishes for the first-time SCFAs reference ranges in serum for women in our region in both early and late pregnancy. This information can be useful to monitor pregnancy follow-up and detect risk values.

Design, development and validation of Food Frequency Questionnaires for the diabetic population: protocol for a systematic review and meta-analysis.

INTRODUCTION: The Food Frequency Questionnaire is one of the most widely used tools for estimating nutritional intake in epidemiological studies. No study has been systematically performed to comprehensively explore Food Frequency Questionnaires designed, developed and validated specifically for the diabetic population (FFQs-DDV-DiaP). Therefore, a systematic review and meta-analysis will be carried out in order to identify and describe FFQs-DDV-DiaP; to examine their design, development, validity and reproducibility; as well as to estimate the overall degree of correlation and agreement; and to evaluate the factors that affect them. METHODS AND ANALYSIS: A systematic literature review will be performed in PubMed/MEDLINE, Scopus and Web of Science to find potentially relevant studies. Original studies related to the design, development, as well as the assessment of the validity and reproducibility of FFQs-DDV-DiaP; reported in English or Romance languages will be selected. Independent reviewers will select studies, extract relevant data and assess FFQs-DDV-DiaP quality. Data will be pooled using the generic inverse-variance method with random-effects models and expressed as correlation coefficients or mean differences with 95% CIs to examine the global validity and reproducibility of FFQs-DDV-DiaP. Heterogeneity will be evaluated by the Cochran Q-statistic and quantified by the I2 statistic. Stratified analyses and random-effects meta-regressions will be performed to explore heterogeneity and whether any covariate influences the effect sizes. Finally, publication bias will be assessed through the Begg's and Egger's tests. ETHICS AND DISSEMINATION: This systematic review and meta-analysis will not use confidential personal data. Therefore, the requirement of ethical approval or informed consent is not necessary. The results of this review will be disseminated only in peer-reviewed publications or at relevant scientific conferences. PROSPERO REGISTRATION NUMBER: CRD42021268575.

Changes in fatty acid levels (saturated, monounsaturated and polyunsaturated) during pregnancy.

BACKGROUND: During pregnancy a high amount of fatty acids (FA) is necessary to meet foetus demands, which vary during gestation. The present study describes the changes in maternal fatty acid concentrations during pregnancy in a sample of pregnant women. METHODS: This is a longitudinal study of 479 pregnant women who were monitored from the first trimester to third trimester of pregnancy. Data on maternal characteristics were recorded and a serum sample was collected in each trimester. The fatty acid profile (saturated (SFA: total, lauric acid, myristic acid, palmitic acid, stearic acid), monounsaturated (MUFA: total, palmitoleic acid, oleic acid) and polyunsaturated fatty acids (PUFA: total omega-6 (n-6), linoleic acid, dihomo-γ-linolenic acid, arachidonic acid (AA), total omega-3 (n-3), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA)) was analysed with a gas chromatography-mass spectrometry combination. RESULTS: From the first trimester to third trimester of pregnancy, a significant increase in total SFA, total MUFA and total n-6 PUFA was found. (p < 0.001). Nevertheless, the serum concentration of arachidonic acid (AA), eicosapentaenoic acid (EPA) and total n-3 PUFA decreased during gestation (p < 0.001). A statistically non-significant result was observed for the docosahexaenoic acid (DHA) serum concentration between the first and third trimesters of pregnancy. Significant correlations were observed between each total fatty acid concentrations of the first and third trimesters. CONCLUSION: The circulating serum concentration of SFA, MUFA and n-6 PUFA increases during pregnancy, whereas essential fatty acids such as AA and EPA decrease, and DHA remains unchanged. Further research is necessary to understand the role played by FA throughout gestation.

Maternal Factors Associated with Levels of Fatty Acids, Specifically n-3 PUFA during Pregnancy: ECLIPSES Study.

An optimal fatty acid (FA) profile during pregnancy, especially docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), is essential for the health of the mother and child. Our aim was to identify the socioeconomic and maternal lifestyle factors associated with serum FA concentration in pregnant women. A longitudinal study was conducted on 479 pregnant women, who were assessed during the first (T1) and third (T3) trimesters of pregnancy. Data on maternal characteristics, food consumption, and lifestyle were collected. Serum FA concentrations were analysed by a gas chromatography-mass spectrometry combination. The multiple linear regression showed that high educational level and older age were significantly associated with higher EPA and DHA concentrations and lower values of n-6/n-3 and arachidonic acid (AA)/EPA in T1 and/or T3. Regarding diet-fish and seafood consumption increased EPA concentration and reduced n-6/n-3 and AA/EPA values in both trimesters, whereas its consumption increased DHA concentration only in T1. Smoking was associated with lower DHA concentration in T1 and higher values of n-6/n-3 ratio in both trimester. Overweight and obesity were associated with higher values of n-6/n-3 ratio and AA/EPA ratio in T1. A statistically non-significant association was observed with saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA). In conclusion, high educational levels, older age, fish, seafood consumption, and/or non-smoking, are factors that influence better omega-3 polyunsaturated fatty acid (n-3 PUFA) profile in both trimesters of pregnancy. Further research is needed to go in-depth into these findings and their health consequences.

Nutrient Intake during Pregnancy and Post-Partum: ECLIPSES Study.

Pregnancy and post-partum are critical periods in which nutritional intake is essential to maternal and child health. Our aim was to describe dietary intake during pregnancy and post-partum and assess its adequacy. A longitudinal study was conducted on 793 pregnant women. Data about maternal characteristics, health, diet and lifestyle were assessed. Energy and nutritional intake were compared to the Recommended Dietary Allowances (RDA). The results showed that the intake of energy (82.6%), protein (80.6%) and carbohydrate (99.5%) was adequate (above 80% of RDA) during pregnancy, as were vitamins C, B2 and B12; but vitamin D, iron and folate intake were a long way from RDA (below 35%). Similar results were observed for the post-partum period although fiber, and vitamins E and C decreased compared to intake during pregnancy. In conclusion, although nutritional requirements increase during gestation, pregnant women did not increase their energy and nutritional intake during pregnancy and postpartum and they had a high risk of deficient intake of vitamin D, iron and folates during pregnancy, and therefore, of developing an unfavorable nutritional status, contrary to health recommendations. These findings underscore the necessity of intensive nutrition programs during and after pregnancy.

The Effectiveness of Different Doses of Iron Supplementation and the Prenatal Determinants of Maternal Iron Status in Pregnant Spanish Women: ECLIPSES Study.

Iron deficiency (ID), anemia, iron deficiency anemia (IDA) and excess iron (hemoconcentration) harm maternal-fetal health. We evaluated the effectiveness of different doses of iron supplementation adjusted for the initial levels of hemoglobin (Hb) on maternal iron status and described some associated prenatal determinants. The ECLIPSES study included 791 women, randomized into two groups: Stratum 1 (Hb = 110-130g/L, received 40 or 80mg iron daily) and Stratum 2 (Hb > 130g/L, received 20 or 40mg iron daily). Clinical, biochemical, and genetic information was collected during pregnancy, as were lifestyle and sociodemographic characteristics. In Stratum 1, using 80 mg/d instead of 40 mg/d protected against ID on week 36. Only women with ID on week 12 benefited from the protection against anemia and IDA by increasing Hb levels. In Stratum 2, using 20 mg/d instead of 40 mg/d reduced the risk of hemoconcentration in women with initial serum ferritin (SF) ≥ 15 µg/L, while 40 mg/d improved SF levels on week 36 in women with ID in early pregnancy. Mutations in the HFE gene increased the risk of hemoconcentration. Iron supplementation should be adjusted to early pregnancy levels of Hb and iron stores. Mutations of the HFE gene should be evaluated in women with high Hb levels in early pregnancy.

Food Consumption during Pregnancy and Post-Partum. ECLIPSES Study.

Inadequate maternal diet can adversely affect mother and child. Our aim was to assess adherence to the Spanish dietary guidelines and to the Mediterranean diet, to analyze changes in diet during pregnancy and post-partum, and to identify maternal factors associated with food consumption. A total of 793 healthy pregnant women were recruited during the first prenatal visit and followed until the post-partum period. Data from the clinical history, anthropometric measurements, and lifestyle habits were collected. Food consumption was evaluated using a food frequency questionnaire. The results show that in pregnant women the consumption of healthy foods did not meet recommendations, whereas consumption of red and processed meat and sweet food exceeded recommendations. The results also show a medium adherence to the Mediterranean diet that remained unchanged throughout pregnancy. A significant decrease was observed in the consumption of fruits, followed by vegetables and then salted and sweet cereals from pregnancy to post-partum. A better adherence to the Mediterranean diet has been reported by pregnant women that are older, of higher social class, and higher education level, and who do not smoke nor drink (p < 0.005). In conclusion, the diet of pregnant women from Spain departs from recommendations, medium adherence to the Mediterranean diet was maintained throughout the pregnancy and post-partum, and a decreasing consumption of healthy food from the first trimester to the post-partum period was observed. Maternal factors such as age, social class, education, and smoking influence diet quality.

Ingesta de azúcares libres y exceso de peso en edades tempranas. Estudio longitudinal / Consumption of free sugars and excess weight in infants. A longitudinal study

Introducción: El consumo de azúcares libres se ha relacionado con el exceso de peso, recomendando la OMS una ingesta < 10% de la energía total. El objetivo fue valorar la asociación entre el consumo de azúcares libres a los 12 meses y el riesgo de exceso de peso a los 30 meses en niños sanos. Material y métodos: Estudio longitudinal en 81 niños seguidos desde el nacimiento hasta los 30 meses. Se registró: historia clínica y antropometría al nacer, a los 12 y 30 meses. Se clasificó el estado ponderal en con y sin exceso de peso, según los valores de la OMS. A los 12 meses se analizó la ingesta de energía y nutrientes diferenciando la ingesta de azúcares libres y azúcares naturales. Se realizaron análisis multivariantes ajustados por las principales variables confusoras. Resultados: Un 40,4% de los niños de 12 meses realizaron ingestas de azúcares libres superiores a las recomendadas, siendo significativamente mayores en los niños con exceso de peso a los 30 meses (60,9%). La mayor ingesta de azúcares libres a los 12 meses se asocia a un mayor riesgo de exceso de peso a los 30 meses (OR: 1,136; IC 95%: 1,033-1,248). Conclusiones: Los lactantes de 12 meses realizan una ingesta de azúcares libres muy superior a la recomendada. Esta ingesta elevada podría ser un factor de riesgo de exceso de peso ya en edades tempranas

Introduction: The consumption of free sugars has been related to excess weight, with the WHO recommending an intake of < 10% of total energy. The aim of this study is to assess the association between the consumption of free sugars at 12 months and the risk of excess weight at 30 months in healthy children. Material and methods: A longitudinal study was conducted on 81 children followed-up from birth to 30 months. A record was made of the clinical history and anthropometry, at birth, and at 12 and 30 months. Weight status was classified as with or without excess weight, according to WHO values. At 12 months, the intake of energy and nutrients was analysed by differentiating the intake of free and natural sugars. Multivariate analyses adjusted for the main confounding variables were performed. Results: Free sugars were consumed by 40.4% of the 12-month-old children, being higher than that recommended, and being significantly higher in children with excess weight at 30 months (60.9%). The higher intake of free sugars at 12 months is associated with an increased risk of excess weight at 30 months (OR: 1.130, 95% CI: 1.032-1.238). Conclusions: The consumption of free sugars is much higher than that recommended in 12-month-old infants. This high intake could be a risk factor for excess weight, even at early ages

Emotional Symptoms and Dietary Patterns in Early Adolescence: A School-Based Follow-up Study.

OBJECTIVE: To examine the relationship between early emotional symptoms and dietary patterns over 3 years in a school-based sample. DESIGN: Three-year longitudinal prospective study. SETTING: Thirteen schools in Reus, Spain. PARTICIPANTS: From a sample of 562 preadolescents with and without emotional symptoms, 165 were observed and were classified as either showing (n = 100) or not showing emotional symptoms (n = 65). MAIN OUTCOME MEASURE: Emotional symptoms were assessed at baseline and after 1 and 3 years. In the third year, data were collected on food consumption, adherence to the Mediterranean diet (MD), and physical activity. ANALYSIS: Dietary patterns were created by principal component analysis. Multivariate logistic regression was conducted with P < .05 considered significant. RESULTS: Girls with emotional symptoms scored significantly lower in assessments for MD (score of 5.41 ± 2.19) and physical activity (score of 4.97 ± 2.05) than did girls who had no emotional symptoms (scores: MD, 6.19 ± 1.67; physical activity: 5.86 ± 1.94). Approximately 39.68% of girls with emotional symptoms showed high adherence to a sweet and fatty food pattern. After adjusted logistic regression, girls with emotional symptoms were 4 times as likely to have high adherence to a sweet and fatty food pattern (odds ratio, 4.79; 95% confidence interval, 1.55-15.10). No differences were observed among boys. CONCLUSIONS AND IMPLICATIONS: Girls with emotional symptoms during early adolescence have high adherence to a pattern rich in sweet and fat foods and low adherence to MD, and engage in low levels of physical activity. These findings highlight the importance of managing emotional distress to prevent it from having a negative effect on eating behavior.

Longitudinal study of psychopathological, anthropometric and sociodemographic factors related to the level of Mediterranean diet adherence in a community sample of Spanish adolescents.

OBJECTIVE: The Mediterranean diet (MD) pattern has important health benefits; however, it seems that Spanish school-aged children have been abandoning this healthy pattern recently. We aimed to identify psychopathological, anthropometric and sociodemographic factors that may influence the risk of low MD adherence. DESIGN: Longitudinal study in three phases. MD adherence was assessed using the Krece Plus food questionnaire and psychopathological symptoms using the Screen for Childhood Anxiety Related Emotional Disorders, Children's Depression Inventory, Youth's Inventory-4 and Eating Disorder Inventory-2. Anthropometric data were collected in the first and third phases. Settings All five representative areas in Reus, Spain. SUBJECTS: Adolescents (n 241). RESULTS: Regardless of past and current BMI, socio-economic status was a protective factor for low MD adherence (OR=0·805, P=0·003) and a risk factor for high BMI (OR=0·718, P=0·002; OR=0·707, P=0·001). Regardless of socio-economic status, depression was involved with risk of low adherence (OR=1·069, P=0·021). Girls with lower MD adherence presented significantly higher scores for eating disorders measured using the Eating Disorder Inventory-2 (low adherence, mean 18·9 (sd 13·5); high adherence, mean 8·9 (sd 9·0), P=0·020) and the Youth Inventory-4 (low adherence, mean 5·2 (sd 4·3); medium adherence, mean 3·6 (sd 3·2), P=0·044). They also presented higher depression symptoms (low adherence, mean 17·7 (sd 9·6); medium adherence, mean 12·3 (sd 7·2), P=0·01) than girls with high adherence. CONCLUSIONS: The results highlight the influence of psychosocial factors on levels of MD adherence. These factors need to be taken into account when developing prevention and health promotion initiatives.

Association study of monoamine oxidase-A gene promoter polymorphism (MAOA-uVNTR) with self-reported anxiety and other psychopathological symptoms in a community sample of early adolescents.

The polymorphism upstream of the gene for monoamine oxidase A (MAOA-uVNTR) is reported to be an important enzyme involved in human physiology and behavior. With a sample of 228 early-adolescents from a community sample (143 girls) and adjusting for environmental variables, we examined the influence of MAOA-uVNTR alleles on the scores obtained in the Screen for Childhood Anxiety and Related Emotional Disorders and in the Child Symptom Inventory-4. Our results showed that girls with the high-activity MAOA allele had higher scores for generalized and total anxiety than their low-activity peers, whereas boys with the low-activity allele had higher social phobia scores than boys with the high-activity allele. Results for conduct disorder symptoms did not show a significant relationship between the MAOA alleles and the presence of these symptoms. Our findings support a possible association, depending on gender, between the MAOA-uVNTR polymorphism and psychopathological disorders such as anxiety, which affects high rates of children and adolescents.

Dietary intake and nutritional risk in Mediterranean adolescents in relation to the severity of the eating disorder.

OBJECTIVE: To assess the relationship between the degree of severity of eating disorders (ED) and energy and nutrient intakes and nutritional risk in a mixed-sex adolescent population without clinical symptoms. DESIGN: Cross-sectional study. SETTING: Data were collected in schools. SUBJECTS: Adolescents (n 495) aged 14·2 (sd 1·0) years. The Eating Attitudes Test was used to detect adolescents at risk of ED (rED) and a structured interview based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, was used to diagnose eating disorder not otherwise specified (EDNOS). Dietary intake was quantified using the 24 h recall method over three days and the probability of inadequate intake was determined. RESULTS: Females presented lower intakes of energy, macronutrients and micronutrients (Ca, Fe, Mg, K, P, Na, thiamin, vitamins E, C, B6, B12, pantothenic acid, folic acid) because the severity of their ED was greater. These lower dietary intakes led to nutritional risk (for Ca, Fe, Mg, P, vitamins A, D, B6) in more than 80 % and 60 % of females with EDNOS and rED, respectively. The multiple linear regression models showed that the rED and EDNOS groups presented a lower energy intake of 1597·4 kJ/d (381·8 kcal/d) and 3153·0 kJ/d (753·6 kcal/d), respectively. In contrast, little difference was observed in the nutritional intakes of males. CONCLUSIONS: The female adolescents showed lower energy and nutrient intakes as the ED became more severe, which led to energy, vitamin and mineral deficiencies in a high percentage of females with ED. These nutritional risks could hinder adequate physical and psychological development and lead to chronic ED.

Psychopathological factors that can influence academic achievement in early adolescence: a three-year prospective study

This three-phase prospective study investigated psychosocial factors predicting or associated with academic achievement. An initial sample of 1,514 school-age children was assessed with screening tools for emotional problems (Screen for Childhood Anxiety and Related Emotional Disorders; Leyton Obsessional Inventory-Child Version; Children's Depression Inventory). The following year, 562 subjects (risk group/without risk group) were re-assessed and attention deficit/hyperactivity disorder (ADHD) was assessed. Two years later, 242 subjects were followed, and their parents informed about their academic achievement. Results showed that early depression (phase 1 B = -.130, p = .001; phase 1 + phase 2 B = -.187, p < .001), persistent anxiety symptoms (phase 1 + phase 2 B = -1.721, p = .018), and ADHD were predictors of lower academic achievement (phase 1 + phase 2 B = -3.415, p = .005). However, some anxiety symptoms can improve academic achievement (Social phobia B = .216, p = .018; Generalized anxiety B = .313, p < .001). Socio-economic status (SES) was positively related to academic achievement. We can conclude that in the transition period to adolescence, school-health professionals and teachers need to consider the emotional issues of students to avoid unwanted academic outcomes (AU)

Adapting iron dose supplementation in pregnancy for greater effectiveness on mother and child health: protocol of the ECLIPSES randomized clinical trial.

BACKGROUND: Currently, there is no consensus regarding iron supplementation dose that is most beneficial for maternal and offspring health during gestation. Recommended iron supplementation dose does not preempt anemia in around 20% of the pregnancies, nor the risk of hemoconcentration in 15%. This deficit, or excess, of iron prejudices the mother-child wellbeing. Therefore the aims of the study are to determine the highest level of effectiveness of iron supplementation adapted to hemoglobin (Hb) levels in early pregnancy, which would be optimum for mother-child health. DESIGN: Randomized Clinical Trial (RCT) triple-blindedSetting: 10 Primary Care Centers from Catalunya (Spain)Study subjects: 878 non-anemic pregnant women at early gestation stage, and their subsequent newborns METHODS: The study is structured as a RCT with 2 strata, depending on the Hb levels before week 12 of gestation. Stratum #1: If Hb from 110 to 130 g/L, randomly assigned at week 12 to receive iron supplement of 40 or 80 mg/d. Stratum #2: If Hb >130 g/L, randomly assigned at week 12 to receive iron supplement of 40 or 20 mg/d. MEASUREMENTS: In the mother: socio-economic data, clinical history, food item frequency, lifestyle and emotional state, and adherence to iron supplement prescription. Biochemical measurements include: Hb, serum ferritin, C reactive protein, cortisol, and alterations in the HFE gene (C282Y, H63D). In children: ultrasound fetal biometry, anthropometric measurements, and temperament development.Statistical analyses, using the SPSS program for Windows, will include bivariate and multivariate analyses adjusted for variables associated with the relationship under study. DISCUSSION: Should conclusive outcomes be reached, the study would indicate the optimal iron supplementation dose required to promote maternal and infant health. These results would contribute towards developing guidelines for good clinical practice.

A prospective study of paediatric obsessive-compulsive symptomatology in a Spanish community sample.

The obsessive-compulsive manifestations course was assessed with the Leyton obsessional inventory-child version survey (LOI-CV) in a 3-year prospective study, using a non-clinical sample. From an initial sample of 1,514 school-age children who underwent symptoms screening for obsessive-compulsive, anxiety and depression, 562 subjects (risk group/without risk group) were re-assessed in the 2nd phase and 242 subjects were monitored after 3 years. LOI-CV scores significantly decreased over time independently of age and gender. The prevalence, persistence and incidence for two levels of severity of obsessive­compulsive manifestations ranged between 4.8-30.4%, 9.3-28.4% and 1.1-14.4%, respectively. 34.6-64.5% of obsessive-compulsive symptomatology was predicted by anxiety, depressive and obsessive-compulsive symptoms. For the obsessiveness (less severe form of obsessive-compulsive manifestations), the depressive symptoms were not predictors. Gender and socioeconomic status were not related with obsessive-compulsive manifestations. These data support a substantial continuity of the obsessive-compulsive manifestations and the existence of different levels of severity within the obsessive-compulsive spectrum.

However, some anxiety symptoms can improve academic achievement (Social phobia B = .216, p = .018; Generalized anxiety B = .313, p < .001). Socio-economic status (SES) was positively related to academic achievement. We can conclude that in the transition period to adolescence, school-health professionals and teachers need to consider the emotional issues of students to avoid unwanted academic outcomes.

Emotional psychopathology and increased adiposity: follow-up study in adolescents.

Based on data from a three-year longitudinal study, we assess the effect, according to gender, of emotional psychopathology in preadolescence on anthropometric and body composition parameters in adolescence (N = 229). Psychopathology was assessed using the Screen for Childhood Anxiety and Related Emotional Disorders, the Children's Depression Inventory and the MINI-International Neuropsychiatric Interview for Kids. Body fat percentage (%BF), waist circumference (WC) and body mass index (BMI) were also determined. Following analysis with adjusted multiple regression models, the results indicated that symptoms of depression and separation anxiety were significantly associated with increased WC and BMI in boys, and that somatic symptoms were associated with increased WC and %BF in girls. Diagnosis of social phobia, panic disorder or dysthymia led to significantly increased WC and/or BMI in boys and dysthymia increased WC in girls. These findings suggest that emotional psychopathology in preadolescence is associated with increased weight gain and abdominal fat in adolescence.
