Physical activity practice and sports preferences in a group of Spanish schoolchildren depending on sex and parental care: a gender perspective.

BACKGROUND: Physical activity plays an important role in the maintenance of health, and it is especially important during childhood. However, the lack of information about differences in physical activity practice and sports preferences of children considering gender differences can result in non-effective policies that enhance inequalities between sexes. The aim of this study is to identify the sports preferences of Spanish schoolchildren and their physical activity practice behaviors depending on their sex and their parental care, analyzing the possible differences from a gender perspective. METHOD: Three hundred sixty-four Spanish schoolchildren (179 girls, 185 boys) participated in this cross-sectional study. A daily physical activity questionnaire was used to evaluate physical activity level (PAL), moderate-to-vigorous physical activity (MVPA) and sports preferences and a socio-health questionnaire were used to collect data about parental care. Statistical analysis was performed using SPSS and applying Student's T-test for normal variables, Mann-Whitney U-test for non-parametrical variables, and chi-square (χ2) test for categorical variables. Subsequently, odds ratios were used to analyze associations between the physical activity practice of the children and parental care. RESULTS: PAL and time spent in MVPA was significantly lower for girls compared to boys (1.44 ± 0.07 vs. 1.46 ± 0.07, p < 0.001 and 0.74 ± 0.40 h/day vs. 0.90 ± 0.45 h/day; p < 0.001, respectively). Dancing, rhythmic gymnastics, skating, and water sports were practiced more by girls, while football, wrestling sports, handball, and racket sports were practiced more by boys (p < 0.05). Children cared for by their fathers had higher odds for physical activity practice (OR = 1.995 (1.202-3.310), p = 0.008). CONCLUSION: Physical activity among girls was less frequent and less intense. Girls opted for individual sports with artistic connotations, while boys often practiced more team contact sports. Furthermore, children are more physically actives when their father is in charge of them.

Podocytes are new cellular targets of haemoglobin-mediated renal damage.

Recurrent and massive intravascular haemolysis induces proteinuria, glomerulosclerosis, and progressive impairment of renal function, suggesting podocyte injury. However, the effects of haemoglobin (Hb) on podocytes remain unexplored. Our results show that cultured human podocytes or podocytes isolated from murine glomeruli bound and endocytosed Hb through the megalin-cubilin receptor system, thus resulting in increased intracellular Hb catabolism, oxidative stress, activation of the intrinsic apoptosis pathway, and altered podocyte morphology, with decreased expression of the slit diaphragm proteins nephrin and synaptopodin. Hb uptake activated nuclear factor erythroid-2-related factor 2 (Nrf2) and induced expression of the Nrf2-related antioxidant proteins haem oxygenase-1 (HO-1) and ferritin. Nrf2 activation and Hb staining was observed in podocytes of mice with intravascular haemolysis. These mice developed proteinuria and showed podocyte injury, characterized by foot process effacement, decreased synaptopodin and nephrin expression, and podocyte apoptosis. These pathological effects were enhanced in Nrf2-deficient mice, whereas Nrf2 activation with sulphoraphane protected podocytes against Hb toxicity both in vivo and in vitro. Supporting the translational significance of our findings, we observed podocyte damage and podocytes stained for Hb, HO-1, ferritin and phosphorylated Nrf2 in renal sections and urinary sediments of patients with massive intravascular haemolysis, such as atypical haemolytic uraemic syndrome and paroxysmal nocturnal haemoglobinuria. In conclusion, podocytes take up Hb both in vitro and during intravascular haemolysis, promoting oxidative stress, podocyte dysfunction, and apoptosis. Nrf2 may be a potential therapeutic target to prevent loss of renal function in patients with intravascular haemolysis. Copyright © 2017 Pathological Society of Great Britain and Ireland.

Adequacy of usual macronutrient intake and macronutrient distribution in children and adolescents in Spain: A National Dietary Survey on the Child and Adolescent Population, ENALIA 2013-2014.

OBJECTIVES: To describe the nutritional profile and assess the National Dietary Survey on the Child and Adolescent Population project in Spain (ENALIA) regarding usual total energy and macronutrient intake. METHODS: A cross-sectional nationally representative sample of 1862 children and adolescents (age 6 months to 17) was surveyed between 2013 and 2014 following European methodology recommendations. Dietary information was collected using two methods, dietary records (for children from age 6 months to 9 years) and 24-h dietary recall (participants age 10 and older). Usual intake was estimated by correcting for within-person intake variance using the Iowa State University (ISU) method. A probability analysis was used to assess compliance with dietary reference intakes in the target population. RESULTS: Protein consumption in the age 1-3 group as a percentage of total energy exceeded the upper limit of the Acceptable Macronutrient Distribution Range (AMDR) by 4.7% for boys and 12.1% for girls. 42.9% of girls age 4-8 were under the lower limit of the AMDR for carbohydrates. 43.4% of boys and 46.9% of girls between 4 and 17 exceeded the AMDR in total fat intake, saturated fatty acids (SFAs) accounting for 12.3% of total energy. CONCLUSIONS: The results suggest that Spanish children and adolescents could improve macronutrient distribution by reducing fat and increasing carbohydrate intake across all age groups, and decreasing protein intake, especially in young children.

Myocardial deformation and acute cellular rejection after heart transplantation: Impact of inter-vendor variability in diagnostic effectiveness.

PURPOSE: Our objective was to investigate the impact of inter-vendor variability in the ability of myocardial strain analysis to detect acute cellular rejection (ACR) in heart transplant recipients. METHODS: We performed serial echocardiographic examinations in 18 consecutive adult heart transplanted patients, in their first year post-transplantation, within 3 hours of the routine surveillance endomyocardial biopsies (EMB) in a single center. Myocardial strain was analyzed using two software in two different institutions, and inter-vendor variability of strain values and its association with ACR (any grade or grade ≥2R) was investigated. The parameter of comparison was the peak value of the average curve of strain during the entire cardiac cycle. RESULTS: A total of 147 pairs of EMB-echocardiogram were performed, 65 with no ACR, 63 with ACR grade 1R, and 19 with ACR grade ≥2R. Intra-class correlation coefficients for left ventricle longitudinal, radial, and circumferential strain were 0.38, 0.39, and 0.77, respectively, and 0.32 for right ventricular longitudinal strain. Neither software found significant association of left ventricular longitudinal strain with rejection. Grade ≥2R ACR was associated with left ventricular circumferential strain measured with the first software and with left ventricular radial strain with the other; and ACR of any grade was only significantly associated with right ventricle longitudinal strain measured with the first software. CONCLUSIONS: Inter-vendor reproducibility of strain values was low in this study. Some strain parameters were associated to ACR, although these results were inconsistent between two commercially available software. Specific validation of each software is warranted for this clinical indication.

Low Adherence to Dietary Guidelines in Spain, Especially in the Overweight/Obese Population: The ANIBES Study.

OBJECTIVE: The objective of this study was to analyze the dietary intake of the Spanish population according to ponderal status and body fat distribution. METHODS: Data were obtained from ANIBES (Anthropometry, Intake, and Energy Balance in Spain), a cross-sectional study of a nationally representative sample (1013 men, 996 women) of the Spanish population (18-64 years). The final fieldwork was carried out from mid-September to November (three months) 2013. A 3-day dietary record provided information about food and beverage consumption. Height, weight, and waist circumference were assessed, and body mass index (BMI) and waist-height ratio (WHtR) calculated. RESULTS: The Spanish population had a low consumption of fruits and vegetables, cereals, whole cereals, and dairy and high consumption of meat products. Individuals with overweight/obesity (BMI ≥ 25 kg/m2) and abdominal adiposity (WHtR ≥ 0.5) showed lower compliance with dietary guidelines. In the male group, adjusting by age, inadequate consumption of cereals (<4 servings/day) and vegetables and fruit (<5 servings/day) was associated with higher risk of overweight (odds ratio [OR] = 1.704, 95% confidence interval [CI], 1.187-2.447, p = 0.001, for cereals and OR = 3.816, 95% CI, 1.947-7.480, p = 0.001, for vegetables and fruits) and abdominal adiposity (OR = 2.081, 95% CI, 1.419-3.053, p = 0.000 and OR = 4.289, 95% CI, 2.108-8.726, p = 0.001, respectively). CONCLUSION: Nutritional campaigns should be conducted to improve the dietary habits of the Spanish population in general, especially men, who have poorer ponderal status and abdominal adiposity, due to their lower adherence to dietary guidelines.

Differences in meal patterns and timing with regard to central obesity in the ANIBES ('Anthropometric data, macronutrients and micronutrients intake, practice of physical activity, socioeconomic data and lifestyles in Spain') Study.

OBJECTIVE: To study the association of meal patterns and timing with central obesity to identify the best dietary strategies to deal with the increasing obesity prevalence. DESIGN: A cross-sectional study performed on data from a representative sample of the Spanish population. Height and waist circumference were measured using standardized procedures and waist-to-height ratio (WHtR) was calculated. The sample was divided into those without central obesity (WHtR<0·5) and those with central obesity (WHtR≥0·5). SETTING: ANIBES ('Anthropometric data, macronutrients and micronutrients intake, practice of physical activity, socioeconomic data and lifestyles in Spain') Study. SUBJECTS: Adults aged 18-64 years (n 1655; 798 men and 857 women). RESULTS: A higher percentage of people ate more than four meals daily in the group without central obesity and those with central obesity more frequently skipped the mid-afternoon snack than those without. Breakfasts containing >25 % of total energy intake and lunches containing >35 % of total energy intake were associated with increased likelihood of central obesity (OR=1·874, 95 % CI 1·019, 3·448; P15 % of total energy were associated with decreased likelihood of central obesity (OR=0·477, 95 % CI 0·313, 0·727; P<0·001 and OR=0·650, 95 % CI 0·453, 0·932; P<0·05, respectively). The variety of cereals, wholegrain cereals and dairy was higher in the population without central obesity. CONCLUSIONS: Our results suggest that 'what and when we eat' should be considered dietary strategies to reduce central obesity.

ß-Carotene Concentration and Its Association with Inflammatory Biomarkers in Spanish Schoolchildren.

AIM: To examine the correlation between inflammatory biomarkers and plasma ß-carotene levels in children. METHODS: A total of 564 Spanish schoolchildren aged 9-12 were observed and studied. Plasma ß-carotene levels were assessed by HPLC. A ß-carotene level <4.83 µg/dL (0.09 µmol/L) was considered deficient. Plasma tumour necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were measured by immunoenzyme assays. Serum high-sensitivity C-reactive protein (hs-CRP) was tested by immunonephelometry. RESULTS: Subjects who were ß-carotene-deficient (23.1% of the studied children) had higher IL-6 levels than subjects with normal ß-carotene concentrations. The log-IL-6 and log-hs-CRP concentrations, but not the log-TNF-α level, were strongly and inversely related to the plasma log-ß-carotene level (taking into account log-age, energy intake, log-triglycerides, gender, log-body mass index, log-ß-carotene intake, energy from lipids and cholesterol as covariables). When the 3 inflammatory biomarkers were introduced into the regression model along with the corresponding covariables, only the log-IL-6 level was related to the plasma log-ß-carotene level (ß = -0.505 ± 0.078; p < 0.001). CONCLUSIONS: Inflammatory status, in particular IL-6 levels, appears to be negatively associated with plasma ß-carotene levels in schoolchildren.

Sedentary behavior among Spanish children and adolescents: findings from the ANIBES study.

BACKGROUND: An increase of sedentary behaviors far from the Mediterranean lifestyle is happening in spite of the impact on health. The aims of this study were to describe sedentary behaviors in children and adolescents. METHODS: A representative sample of 424 Spanish children and adolescents (38% females) involved in the ANIBES study was analyzed regarding their sedentary behaviors, together with the availability of televisions, computers, and consoles by means of the HELENA sedentary behavior questionnaire. RESULTS: For the total sample of children, 49.3% during weekdays and 84% during weekends did not meet the recommendation of less than 2 hours of screen viewing per day. The use of TV was higher during weekdays (p < 0.05) and there were significant differences between adolescents and children (16.9 vs. 25.1%, p < 0.05). The use of computer, console games and of internet for non-study reasons was higher during weekends (p < 0.001). Adolescents played more computer games and used more internet for non-study reasons than children during both weekdays and weekends (p < 0.05 and p < 0.001, respectively). The use of internet for academic reasons was lower in children (p < 0.001) than adolescents during weekends; however, no significant differences were found between sexes. In addition, more than 30% of the children and adolescents had at least one electronic device in their bedrooms. CONCLUSIONS: Spanish children and adolescents are not meeting the recommendations regarding the maximum of screen viewing (<2 h/day), especially during the weekend, for all of sedentary behaviors. Urgent strategies and intervention studies are needed to reduce sedentary behavior in young people.

[Functional bladder capacity by ultrasound in patients with monosymptomatic primary enuresis]. / Capacidad vesical funcional mediante ultrasonido en pacientes con enuresis primaria monosintomática.

Nocturnal enuresis is a common clinical problem affecting 5% to 10% of school-age children. Etiology is not known but a diminished functional bladder capacity it has been proposed as a predisposing factor. There exist only a few studies evaluating it by ultrasound. OBJECTIVE: To identify if there is a difference of the functional bladder capacity measured by ultrasound between nocturnal enuresis group and healthy children. PATIENTS AND METHOD: A cross-sectional study from February 2014 to May 2015 including two groups, nocturnal enuresis and a control group of 40 patients each, 5 to 15 years old. A single blinded operator measured the functional bladder capacity by ultrasound with an Acuson S2000 SiemensTM 3.5 and 5 MHz transducer. Analytics and descriptive statistics were performed using IBM SPSS 20TM software. RESULTS: Patients with enuresis showed a decreased functional bladder capacity vs. controls (171.7 ml vs 225.5 ml; p = 0.025). A history of first-degree relative with enuresis increased the risk of having enuresis OR = 2.81 (95% CI: 1.06-7.42), a second-degree relative presented OR = 4.0 (95% CI: 1.48-10.78). Functional bladder capacity presented a weak correlation with the bladder capacity estimated by Kaefer’s formula. CONCLUSION: The functional bladder capacity is lower in the patients with nocturnal enuresis when compared to control group. There is little correlation between functional bladder capacity and Kaefer’s formula to determine the normal bladder capacity. We reaffirmed that the family history with enuresis strongly increases the risk of developing nocturnal enuresis.

Antioxidant status in a group of institutionalised elderly people with chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is one of the most important and prevalent diseases suffered by the elderly. Evidence exists that its onset and severity might be conditioned by antioxidant status. The aim of the present study was to investigate the relationship between antioxidant status and COPD in institutionalised elderly people. In all, 183 elderly people aged >65 years (twenty-one had COPD and 160 healthy controls) were studied. The subjects' diets were investigated via the use of precise individual weighing for 7 d. Body weight, height, and biceps and triceps skinfold thickness were measured, and body fat (kg) and BMI (kg/m2) were calculated. Serum retinol, α-tocopherol, ß-carotene and vitamin C levels were determined. Subjects with COPD ate less fruits than healthy controls (117 (sd 52) v. 192 (sd 161) g/d), their coverage of the recommended intake of vitamin C was smaller (150 (sd 45) v. 191 (sd 88) %; note that both exceeded 100 %) and their diets had a lower antioxidant capacity (6558 (sd 2381) v. 9328 (sd 5367) mmol trolox equivalent/d). Those with COPD had lower serum vitamin C and α-tocopherol concentrations than healthy controls (32·4 (sd 15·3) v. 41·5 (sd 14·8) µmol/l and 12·1 (sd 3·2) v. 13·9 (sd 2·8) µmol/l, respectively). In addition, subjects with α-tocopherol <14·1µmol/l (50th percentile) were at 6·43 times greater risk of having COPD than those subjects with ≥14·1µmol/l (OR 6·43; 95 % CI 1·17, 35·24; P<0·05), taking sex, age, use of tobacco, body fat and vitamin E intake as covariables. Subjects with COPD had diets of poorer antioxidant quality, especially with respect to vitamins C and E, compared with healthy controls.

Central Nervous System Metastases in Patients With Cervical Carcinoma.

INTRODUCTION: Cervical cancer (CC) is the most common malignancy throughout developing countries, although considered rare, central nervous system metastasis (CNSm) does occur. OBJECTIVE: This study aimed to describe our experiences and compare them to other published cases. MATERIALS AND METHODS: From May 2009 to August 2015, the files of all patients with CC treated at our referral center were reviewed. RESULTS: We found 27 patients with CC and CNSm. Mean age at the time of CNS diagnosis was 50 ± 11 years, mean interval between initial CC and CNSm was 46 months; the most frequent initial International Federation of Gynecology and Obstetrics stage was IIB with 17 patients followed by IB in 4. Fifty-nine percent of patients had lung metastases at the time CNSm were diagnosed. Headache was the most common symptom, followed by weakness, altered mental status, and ataxia/cerebellar. Mean survival was 8.2 months after CNSm was discovered; 3 patients are still alive. CONCLUSIONS: The present study describes the largest series of patients with CNSm from CC; this rare complication should be suspected in patients with CC who present with headache, ataxia, cranial nerve palsy, visual disturbance, altered mental status, focal weakness, or other neurological symptom, without other plausible explanation.

Does nebulized epinephrine improve the efficacy of hypertonic saline solution in the treatment of hospitalized moderate acute bronchiolitis? A double blind, randomized clinical trial.

BACKGROUND: Nebulized 3% hypertonic saline solution (HSS 3%) has proven to reduce hospital stay in infants with acute bronchiolitis, as compared with nebulized physiological saline solutions. There are no studies assessing the effectiveness of nebulized epinephrine in patients treated with HSS 3%. The aim of this study was to compare the length of stay (LOS) in hospitalized patients treated with HSS 3% with placebo vs. HSS 3% with epinephrine. Secondarily we aimed to assess the effectiveness and safety of both treatments. METHODS: We performed a prospective, randomized, double-blind, parallel-group study, including infants hospitalized for moderate acute bronchiolitis. Both groups received standard life support and were randomly treated with nebulized HSS 3% (7 mL) with either placebo 3 mL or epinephrine 3 mL. Nebulizations were initially administered every four hours and this interval was modified according to the patient's response. RESULTS: Sixty-four infants were included, 32 patients in each group. No statistically significant differences were found between the two groups (P=0.948) in length of stay, disease severity, SatO2, respiratory rate or heart rate. On the third day of hospitalization, severity and respiratory rate in the HSS 3%+E presented a non statistically significant trend to an earlier improvement, (P=0.063 and P=0.096 repectively). No adverse events occurred. Four patients (two from each group) required transfer to the pediatric intensive care unit. CONCLUSIONS: With a third of the final estimated sample, we find a trend to an earlier clinical recovery in the epinephrine group, even though no statistical significant differences in LOS were found. The study needs to be continued until the total sample is recruited.

Relationship between 24 h urinary potassium and diet quality in the adult Spanish population.

OBJECTIVE: To study the relationship between diet quality and 24 h urinary K excretion. DESIGN: K was measured in 24 h urine samples, while diet was studied using a 24 h recall method over two consecutive days. Diet quality was determined using the Healthy Eating Index (HEI). The body weight, height and body composition of all participants were recorded, and the BMI of each calculated. SETTING: Representative members of the adult Spanish population from the FANPE Study ('Fuentes Alimentarias de Nutrientes en Población Española'; Dietary Sources of Nutrients in the Spanish Population). SUBJECTS: The final sample size was 329 participants aged 18-60 years. RESULTS: Participants with a 24 h urinary K excretion ≥ 93 mmol/d (group AP = adequate potassium) had greater self-reported K intakes, consumed more fruit and vegetables, had a more varied diet and had better HEI scores than those with a 24 h urinary K excretion <93 mmol/d (group IP = inadequate potassium). A significant positive correlation was seen between 24 h urinary K and dietary variety and the number of servings of fruits, vegetables and dairy products consumed, and between each of these and the HEI after correcting for age, sex, BMI, coefficient of activity, energy intake and the under-reporting of energy intake. AP participants were less likely to have an inadequate diet (HEI score <50) than IP participants (OR =0.439; 95 % CI 0.201, 0.961; P=0.039). CONCLUSIONS: Diet quality, measured by the HEI, is correlated with 24 h urinary K excretion in Spanish adults.

Dietary total antioxidant capacity and current asthma in Spanish schoolchildren: a case control-control study.

UNLABELLED: The aim of this work was to study the relationship between dietary total antioxidant capacity (TAC) and current asthma in a group of Spanish schoolchildren. A total of 78 Spanish schoolchildren (26 asthmatic and 52 healthy controls) were randomly selected from a cohort of 564 children (9-12 years of age). The weight and height of all subjects were recorded. A questionnaire, completed by the subjects' parents, was used to obtain personal and health information. Current asthma was established when children had ever had asthma, they had been diagnosed with asthma by a physician, and they had been treated with medications at some time in the previous 12 months. Food intake was monitored using a 3-day food record. All consumed foods were converted into energy and nutrients. Dietary TAC was evaluated using the ferric reducing antioxidant power (FRAP), radical-trapping antioxidant parameter (TRAP), and Trolox equivalent antioxidant capacity (TEAC) assays. The TAC measured using all the assays was significantly lower in children with asthma than in children without this condition (2.95 (2.10-3.75) mmol Fe(II)/day vs. 3.70 (3.08-4.49) mmol Fe(II)/day, p < 0.01; 1.50 (1.06-2.05) mmol Trolox equivalents/day vs. 2.10 (1.40-2.65) mmol Trolox equivalents/day, p < 0.05; and 1.60 (1.08-2.00) mmol Trolox equivalents/day vs. 1.85 (1.50-2.68) mmol Trolox equivalents/day, p < 0.05 for FRAP, TEAC, and TRAP, respectively). After adjusting for energy intake, children with FRAP values higher than 3.5 mmol Fe(II)/day (p50) and TEAC values higher than 1.9 mmol Trolox equivalents/day (p50) had 22.6 and 35.0 %, respectively, lower likelihood of suffering asthma episodes than children with lower values. When logistic regression analysis was performed separately for children with nonsmoker and smoker (at least one) parents, the association between dietary TAC and asthma was only observed in the nonsmoker group (OR = 0.257, 95 % CI = 0.107-0.618, p = 0.002 for FRAP; OR = 0.212, 95 % CI = 0.069-0.639, p = 0.006 for TEAC; and OR = 0.264, 95 % CI = 0.091-0.769, p = 0.015 for TRAP assay). CONCLUSION: Dietary TAC may have a favorable role in asthma in children and, specially, in those with nonsmoker parents.

Moderate vitamin D deficiency and inflammation related markers in overweight/obese schoolchildren.

OBJECTIVE: Obesity has been associated with vitamin D deficiency and increased oxidative stress, which can lead to the dysregulation of adipokines and inflammation. The aim of the present work was to examine the association of vitamin D status [25(OH)D] on inflammatory related markers in overweight/obese children. SUBJECTS/METHODS: A total of 137 Spanish schoolchildren between 9 and 12 years of age (31.4% with overweight/obesity) were studied. Being overweight was defined as BMI≥85th percentile and obesity as BMI≥97th percentile using the reference tables of Hernández. Serum 25(OH)D concentrations were measured by chemiluminescent assay. Plasma tumor necrosis factor (TNF-α) and interleukin-6 (IL-6) were measured by immunoenzyme assay. Serum adiponectin was determined using an ELISA kit. Serum high-sensitivity C-reactive protein (hs-PCR) was tested by immunonephelometry. RESULTS: IL-6 concentrations were higher in the overweight/obese children with deficient serum 25(OH)D (<20 ng/mL) than in those in this group but whose serum 25(OH)D concentrations were adequate (≥20 ng/mL). Serum 25(OH)D was inversely associated with IL-6 concentrations in the overweight/obese subjects taking into account different covariates; thus, for every 1 ng/mL rise in the former, the latter fell by 0.160 pg/mL (ß=-0.160±0.068; R2=0.131; p=0.023). The obese subjects with concentrations of ≥25 ng/mL had lower hs-CRP values compared to those with concentrations of <25 ng/mL (0.053±0.035 vs. 0.356±0.613 mg/dL; p=0.035). CONCLUSION: Low serum 25(OH)D was significantly associated high serum IL-6 in overweight/obese children, and with increased hs-CRP in obese children.

High-Protein Processed Foods: Impact on Diet, Nutritional Status, and Possible Effects on Health.

Proteins are macronutrients with multiple health benefits, but excessive consumption can negatively affect health. This study aimed to evaluate the characteristics of a sample of high-protein processed foods (HPPFs), describe how their consumption affects dietary balance, and acquire knowledge of the consumption patterns of these products in a Spanish population. A sample of HPPFs available in supermarkets and on websites was collected. The contribution to recommended protein intakes was calculated using national and international references and considering the single consumption of the HPPFs and the product plus 150 g of meat. Furthermore, an online survey was conducted among a convenience sample. A total of 36 enriched protein products were evaluated. The percentage of proteins in these products ranges from 10 to 88%. The contribution of the protein recommended intake was within a range of 87.4-306.6% and 66.4-232.8% (women and men, respectively), only considering the additional proteins from 150 g of meat. One hundred thirty-nine participants completed the survey; 67.6% affirmed that they had consumed HPPFs, and half consumed them without following any consumption control. Since these products are accessible to everyone in supermarkets and protein intake is generally higher than the recommended limits, regulating the mass sale of HPPFs is essential to ensure they do not lead to protein overconsumption.

Omega 3 and omega 6 fatty acids intake and dietary sources in a representative sample of Spanish adults.

The present study analyzes the intake of omega 3 (n-3 PUFAs) and omega 6 (n-6 PUFAs) and dietary sources in a representative sample of Spanish adults. For this purpose 418 adults (18 - 60 y), from 15 Spanish provinces were studied. The intake of energy and nutrients [specifically, the n-3 polyunsaturated fatty acids (PUFAs,) α-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA); and the n-6 PUFA, linoleic acid (LA)] was determined using a 24-hour recall questionnaire for two days. The Multiple Source Method (MSM) was used to estimate participants’ usual fatty acid intake. The total n-3 PUFAs intake was 1.8 ± 0.60 g/day (ALA: 1.3 ± 0.32, EPA: 0.16 ± 0.14, and DHA: 0.33 ± 0.21 g/day) and n-6 PUFA intake was 11.0 ± 2.7 g/day (LA: 10.8 ± 2.7 g/day). A high proportion of participants did not meet their nutrient intake goals for total n-3 PUFAs (84.7 %), ALA (45.0 %), and EPA plus DHA (62.9 %). The main food sources for ALA were oil, dairy products, and meat; for EPA fish; for DHA, fish, eggs, and meat; and for LA, oils, meat, and cereals. Therefore, an increase in the intake of foods rich in n-3 PUFAs or the use of supplements with n-3 PUFAs might help to improve the n-3 PUFA intake.
