Background: Lockdown due to COVID-19 influenced food habits and lifestyles with potential negative health impact. This study aims to identify patterns of change in eating habits and physical activity during COVID-19 lockdown in Spain and to identify associations with sociodemographic factors and usual habits., Methods: This cross-sectional study included 1155 adults recruited online to answer a 10-section questionnaire. The protocol assessed usual diet by means of a semi-quantitative food frequency questionnaire, usual physical activity (PA) and supplement use, dietary changes, sedentary time, PA, exposure to sunlight, sleep quality, and smoking during confinement. Patterns of dietary change were identified by factor analysis. Factor scores were included in cluster analysis together with change in PA., Results: Six patterns of dietary change were identified that together with PA changes during lockdown defined three clusters of lifestyle change: a cluster less active, a more active cluster, and a third cluster as active as usual. People who were usually less active were more likely to be classified in the cluster that increased physical activity in confinement. Scores of the Healthy Mediterranean-Style dietary pattern were higher in this group. Conclusions: Different patterns of change in lifestyles in confinement suggest the need to tailor support and advice to different population groups.

The association between breakfast quality and total diet quality of children and adolescents ((1-17.9 years ( n = 1570)) from the National Dietary Survey on the Child and Adolescent Population in Spain (ENALIA) was analyzed. Dietary information was collected using two non-consecutive one-day food diaries (1-10 years old) or two 24 h dietary recalls (>10 years). Breakfast quality index (BQI) and a variant of Nutrient Rich Foods index (NRF9.3) were calculated to assess the total diet quality. Children and adolescents who had breakfast on at least one day ( n = 1561) were divided into two groups according to BQI: Worse Quality Breakfast (WQB) (BQI < 4 points (P66), n = 781) and Good Quality Breakfast (GQB) (BQI ≥ 4, n = 780). Younger children and those whose parents have university education presented higher BQI. GQB group had significantly higher intakes of micronutrients (vitamins A, D, C, B 1 , B 2 , B 6 , niacin, folate, calcium, potassium, magnesium). Fewer GQB children exceeded the Acceptable Macronutrient Distribution Range for fat and had folate and calcium intakes below their estimated average requirement. Daily NRF9.3 was 496.2 ± 54.0, being higher in GQB (503.8 ± 50.6 vs. 488.6 ± 56.2, p < 0.001). Increasing the quality of breakfast increased the possibility of having a NRF9.3 higher than P 50 (OR: 1.893, CI: 1.549-2.315, p < 0.0001). Breakfasts have room for quality improvement in a high percentage of children. A higher quality breakfast is associated with a benefit in the quality of the total diet.

Background: Sodium intake is excessive among Spanish children, but the salt use behaviors of parents and children are unknown. This study aims to determine behaviors related to salt intake in both schoolchildren and parents and the relationship between parental behaviors and 24 h urinary sodium excretion (UNa-24h) in children., Subjects and Methods: A convenience sample was taken from a cross-sectional analysis. Parents completed a self-reported questionnaire about their behaviors related to salt, and their responses were compared with the UNa-24h of their own children. The median test was used to identify differences in UNa-24h according to behaviors. Logistic regression was used to assess the relationship between the behaviors of parents and high sodium excretion in the children and the risk of children's use of table salt, adjusting for age, sex, and BMI. Multinomial logistic regression models, adjusted by the covariates, were used to study the children's salt preferences., Results: A total of 329 schoolchildren from different Spanish provinces were included in the study (mean age: 9.0 ± 1.2 years, 157 girls). The majority of families (parents mean age: 42.0 ± 5.2 years) reported adding salt to food during cooking (92%), and 59% of them never looked at the sodium content on food labels. However, none of these behaviors were related to UNa-24h (p > 0.05). The use of iodized salt (53%), the presence of a salt shaker on the table (6%), and the use of table salt by fathers (57%), mothers (52%) or children (17%) increased the odds (p < 0.05) of children having a higher UNa-24h. Checking sodium content on food labels and the use of table salt by the children or father was associated with a lower preference for salty foods (p < 0.05)., Conclusions: It is important to make parents aware of the relationship between their behaviors regarding the use of discretionary salt and their children's sodium intake. Our data suggest that salt-specific education programs on how to reduce salt both in-home and outside the home should be implemented to improve behavior skills related to salt consumption in parents and children., Competing Interests: The authors have declared that no competing interests exist.

Background: The frequency of intake of food and beverages depends on a number of ill-defined behaviour patterns. The objectives of this study were to evaluate the effects of screen time and sleep duration on food consumption frequency, and to describe frequencies and types of food consumption according to BMI category and parents' level of education., Methods: We studied 6287 and 2806 children drawn from the 2011 and 2013 cross-sectional ALADINO studies respectively. Data were collected on number of hours of sleep, screen time, and weekly frequency of consumption of 17 food groups. Weight status was measured, and information was also collected on parents' educational level. Average food consumption frequencies were calculated by reference to hours of sleep and hours of screen time, and were defined as ≥4 times or <4 times per week (once per week for soft drinks and diet soft drinks). Differences in frequency were evaluated for screen times of more and less than 2 h per day, and for sleep durations longer or shorter than the daily average. We fitted logistic regression models to evaluate the independent association between screen exposure and hours of sleep on the one hand, and food consumption frequency on the other., Results: Consumption of fruit and vegetables was lower among children who had parents with no formal or only primary school education. High levels of screen time were associated with a greater frequency of consumption of energy-dense, micronutrient-poor products and a lower frequency of consumption of fruit and vegetables. Sleeping a sufficient number of hours was associated with a higher consumption of fruit and vegetables. The results for 2011 were concordant with those for 2013., Conclusions: If efforts to ensure healthier eating habits among children are to be at all successful, they should focus on promoting a sufficient amount of sleep for children, limiting the time they spend watching television and/or playing with computers or video games, and educating parents accordingly.

Objectives: Hypertension is a common health problem and with severe health impacts, underdiagnosed and modulated by dietary habits, lifestyle and intake of several nutrients, so analyze the latest data on the involvement of nutrition in preventing and control of hypertension is the subject of this review. Methods: Literature search regarding the topic. Results: Although the best known and followed patterns are the restriction in sodium intake, weight control, and moderation in alcohol consumption; improving diet (increasing consumption of cereals, vegetables, fruits...) and physical activity seem to have a major impact on the control of blood pressure, also consume less saturated fat (with increased MUFA and omega-3), adequate intake of calcium, magnesium, protein, vitamin D and fiber and improving the antioxidant capacity of the diet can have great importance in fighting the problem of hypertension. Given that the average Spanish diet does not meet the advised requirements for many of the nutrients mentioned as favorable in control of the blood pressure, an approximation of the diet to the theoretical ideal can be very helpful in the fight against this problem that has great health impact. Conclusions: Improving feeding, increasing the intake of vegetables, legumes, whole grains, dairy, fish, avoiding an inadequate supply of nutrients (especially calcium, magnesium, protein, and vitamin D) can have a greater benefit in controlling blood pressure, than most widespread monitoring restrictive guidelines in practice.

Introduction and Aims: Taking into account the sanitary importance of the contribution of omega 3 and omega 6 fatty acids and given the scarcity of studies on the subject in Spanish collectives, the aims of the present study were to determine the intake of these fatty acids, their adequacy to the established nutritional goals and food sources in a representative sample of the Spanish population., Methods: A group of 1,068 adults (521 men and 547 women) with ages ranging from 17 and 60 years were studied. The subjects were selected from ten Spanish provinces to constitute a representative sample of the nationwide population. The intakes of polyunsaturated fatty acids (PUFA), omega-3 fatty acids, α-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), omega-6 fatty acids, linoleic acid (LA) and arachidonic acid, expressed in g/day and percentage of the total energy intake, were determined by using a food record for 3 consecutive days, including a Sunday. Personal, anthropometric and sanitary data of individuals were also studied., Results and Discussion: The intake of total fat and saturated fat was higher than the established as advisable in 89.2% and 93.3% of the studied subjects, respectively. The opposite was observed for the intake of PUFA, where an insufficient contribution was most frequent (79.2% of the subjects have an intake less than the 6% of the energy). The contribution of omega-3 fatty acids (1.85±0.82 g/day) is particularly low, and provides less than 1% of the energy in 85.3% of subjects. Specifically the ALA (1.40±0.55 g/day) did not exceed the 0.5% of energy in 53.7% of the cases, and the EPA + DHA (0.55±0.58 g/day) did not exceed 0.5 g/day in 64.6%. On the other hand, the contribution of omega-6 was more appropriate (10.95±3.79 g/day), specifically for LA intake (10.77±3.76 g/day), representing less than 3% of the energy in the 25.5 % of subjects. The main food sources for omega-3 were fish, followed by meat, dairy and fats/oils, whereas for omega-6 were fats/oils, meat and cereals. Taking into account that the low consumption of omega-3 fatty acids is noteworthy in the studied group, especially for EPA + DHA, the influence of the fish consumption is important, since people who consume less than 0.5 servings/day (29.8%) have intakes of omega-3 (1.46±0.57 g/day) and EPA + DHA (0.19±0.19 g/day) significantly lower than individuals with a higher consumption of fish (which have intakes of omega-3 and EPA + DHA of 2.02±0.85 g/day and 0.70±0.61 g/day, respectively) (p < 0.001). The increase in fish consumption facilitates meeting the nutritional goals set for omega-3 (≥ 1% of energy) (OR 0.371, 95% CI 0.306-0.451, p < 0.001) and for EPA + DHA (> 0.5 g/day) (OR 0.121, 95% CI 0.092-0.158, p < 0.001)., Conclusions: Due to the high percentage of individuals who do not meet the nutritional goals set for omega-3, ALA, EPA and DHA, it would be advisable to increase the consumption of fish and/or foods enriched with these fatty acids in order to obtain nutritional and health benefits., (Copyright AULA MEDICA EDICIONES 2013.

Objective: To know the dietary habits of a population of women with overweight/obesity and their knowledge on the concept of proper feeding in order to design nutrition educational campaigns focused on this population., Materials and Methods: A group of 67 women, aged 20 to 35 years with body mass index 24-35 kg/m2 were asked about their frequency of food intake and what they thought to be correct to achieve a balanced diet., Results: Studied women more frequently consumed oils (4.3 +/- 4.5 times/week) and sweets (2.5 +/- 3.6 times/week) and less frequently water (-19.1 +/- 22.7 times/week), vegetables (-4.3 +/- 5.7 times/week), fruits (-3.7 +/- 6.2 times/week), legumes (-1.3 +/- 2.0 times/week) and fish (-2.2 +/- 3.7 times/week) than what they thought they should consume. When comparing what they declare to consume to what has been established as minimal recommended intake for the different groups of foods it is observed that the intake of grains and legumes, fruits and vegetables, and slightly less that of fish and eggs, should de increased., Conclusions: given the incorrect dietary habits observed in a population of women with overweight/obesity, it should be convenient to carry out nutrition educational campaigns. This education could help improve the diet of all the population and the occurrence of overweight and obesity could be prevented in many cases. Besides, in those cases in which the pathology is already present, this could prevent following regimens that are harmful for the health and for weight management.

A study was conducted on the influence of maternal education level on food consumption, energy and nutrient intake, and dietary adequacy in 110 pre-school children from Madrid, Spain. With increasing maternal education, children consumed more sugar(p < 0.05), fruit (p < 0.05), and fish (p < 0.05). Snacking was more frequent with decreasing maternal education (p < 0.05). Though statistical significance was not reached, the consumption of pre-cooked foods was greater among children of mothers educated to a higher level, a phenomenon probably related to the work situation of these women. With respect to dietary composition, no significant differences were found between groups for macronutrient, fiber and energy intakes, except for energy supplied by polyunsaturated fatty acids (PUFA), which was greater in the children of less educated women (p < 0.01). This is probably due to their greater consumption of sunflower seed oil. The diets of children belonging to well-educated mothers came closer to meeting the recommended intakes for folate, vitamin C, and iodine. It would seem that maternal educational level influences the food habits of children. Mothers with less education may require special advice in this area.

Objective: To determine the relationships between habitual breakfast habits and performance in verbal aptitude, logical reasoning and mathematical tests in a group of well-nourished scholars from Madrid., Design: The study subjects were 180 children between 9 and 13 y of age. A dietetic study was undertaken using a 7-day food record. Scholastic aptitude was examined using the scholastic aptitude test (SAT-1) test., Results: Breakfast made up 19.1% of total daily intake. No differences were found between subjects in terms of personal data or total diet with respect to whether they habitually took adequate breakfasts (AB) (ie, more than 20% of daily energy being provided by this meal) or inadequate breakfasts (IB) (less than 20%). However, AB subjects achieved better reasoning scores in the SAT-1 test., Conclusions: The normal breakfast habits of schoolchildren should be taken into account when studying diet-mental function relationships, even when studying well-nourished populations.

Objective: The aim of this study was to determine the desire to lose weight in a group of university students, and to analyse the influence of this desire on declared food habits. The degree of knowledge on what constitutes a balanced diet was also determined., Design: Cross-sectional population survey., Subjects: The study subjects were 234 university students (48 males and 186 females) aged 22.3+/-1.5 y. The weight and height of each were recorded. All subjects were questioned on their desire to lose weight, habitual food intake frequencies, and about what they considered to constitute a balanced diet., Results: Approximately half the population (47.9%), both male (47.8%) and female (47.9%), expressed a desire to lose weight, even though the percentage of overweight students was low (11.1% overall, although much greater among male students [39.6%] than female students [3.8]). The body mass index (BMI) of those who wanted to lose weight was greater than that of those who did not. Nonetheless, the majority of subjects (especially females) showed BMIs within the normal range (18-25 kg/m(2)). Among those who wished to lose weight, the consumption of sweet foods was lower - although these subjects believed they ought to consume even less. It was also thought necessary that egg consumption be reduced, although no differences were recorded in declared consumption between those who wished to lose weight and those who did not., Conclusions: The results show that there is great concern over body weight, although no great differences were seen in the food habits and nutrition knowledge of those who wished to lose weight and those who did not.

The aim of the present study was to analyse the differences between the breakfast habits of obese/overweight (O) (those with body mass index [BMI] above the 75th percentile) and normal weight schoolchildren (N) (those with BMI equal to or below the 75th percentile). A seven consecutive days "food record" was used to record the intake of foods at breakfast and throughout the rest of the day. O subjects, and in particular female O subjects, omitted breakfast more frequently and took significantly smaller quantities of cereals than did N subjects. The energy supplied by breakfast, measured as a percentage of energy expenditure, was significantly lower in O subjects (17.0 +/- 8.5% in males and 14.6 +/- 6.1% in females) than in N subjects (20.9 +/- 9.4% in males and 17.6 +/- 6.5% in females). With respect to the energy and nutrients supplied by breakfast, O subjects took lower quantities of carbohydrates, thiamin, niacin, pyridoxine, vitamin D and iron than did N subjects. The energy profiles of O subjects breakfasts were more imbalanced than those of N subjects. A significant difference was seen between the amounts of energy supplied by carbohydrates. Without doubt, O subjects have less satisfactory breakfast habits than N subjects. This might be a reflection of whole diet that is less adequate, however, it is possible that an inadequate breakfast contributes to the making of poor food choices over the rest of the day, and, in the long term, to an increased risk of obesity.

The aim of this investigation was to study the relationship between concern about nutrition and food consumption in 533 university students (112 men and 421 women), aged 21.7 +/- 2.1 years old. Fish, dairy products and fruit were consumed in quite satisfactory quantities though cereals and vegetables were consumed less frequently than recommended. Men were found to consume greater quantities of milk, meat, bread and alcoholic drinks, while women ate more fruit and vegetables than men. 35.4% of subjects said they were especially concerned about the intake of fat and cholesterol, 24.5% expressed special interest in weight control and 18.2% recorded worries about the intake of vitamins and minerals. 21.6% of subjects expressed no worries at all. Multiple regression analysis showed no differences in concern about nutrition with respect to the sex or body mass index (BMI) of subjects. However, as age increased, the number of subjects expressing no concern fell whilst worries over the quantity of vitamins and minerals in the diet increased. Worries about bodyweight were found to rise with BMI. However, amongst those who wanted to lose weight, 42.2% of women and 7.4% of men had a BMI < 20 kg/m2. These persons, already very slim (below recommended values), still wished to lose weight and could become susceptible to nutritional imbalances. Relationships between concerns and food habits were scarce. Although fat and cholesterol were a concern in theory, the consumption of foodstuffs such as meat and eggs was quite high. However, relationships were found between concern over the vitamin and mineral content of the diet and the intake of supplements, and concern over bodyweight and intake of products that aid slimming. Nutrition educators may find this information useful in the design of their messages and educational programs.

Objective: To compare the food, energy, macronutrient and micronutrient intake of patients with gallstones to those of a control group of similar demographic characteristics., Design: Patient-control study., Subjects: 54 gallstone patients and 46 control subjects., Methods: Two 24-hour dietary recalls and a "food frequency intake" questionnaire were obtained from patients and controls. In both groups, the presence/absence of gallstones was confirmed by ultrasonography. Participants answered a questionnaire on their physical activity patterns., Results: Gallstone patients consumed less food per day (g/day) and less fish and fruits than did control subjects. They also showed greater intakes of cereals, oils, sugars and meats than did control subjects and ate fewer meals per day, tending to omit evening snacks and more substantial evening meals. Further, patients spent less time walking and slept more than did control subjects. They also experienced fluctuations in body weight with greater frequency. Patients consumed more total calories (energy) and fats (especially monounsaturated fatty acids and saturated fatty acids), and less fiber, folate and magnesium than did control subjects. Women with gallstones were shown to have significantly higher intakes of total fats, monounsaturated fatty acids, saturated fatty acids and cholesterol, and significantly lower intakes of fiber, folate, magnesium, calcium and vitamin C than control women. For all vitamins and minerals studied, patients showed a greater percentage of intakes below those recommended., Conclusions: Dietary intervention might provide a method of avoiding the recurrence of gallstones as well as a method of prevention control subjects.

Objective: The objective of this study was to investigate the differences between the foods, energy and nutrient intakes of normal weight and overweight/obese adolescents., Material and Methods: To this end, a survey was made of the food, energy and nutrient intake of 60 adolescents. The subjects kept a 5-day dietary record, including one Sunday. Adolescents were divided into two study groups:overweight and obese subjects (S; with a body mass index-BMI > or = 23 Kg/m2, 75th percentile) and subjects of normal weight (PN; BMI < 23 Kg/m2)., Results: We found no differences in the energy intake between obese and normal adolescents. Imbalances in the contribution of macronutrients to the total energy intake appear greater in overweight/obese adolescents with a greater proportion of their energy from fats and a lower percentage of their energy from carbohydrates. In addition, S subjects take-in significantly larger amounts of cholesterol. The situation was worse in S women who took 50% of their calories derived from fat, 21.9% from proteins and only 27.5% of their calories were derived from carbohydrates., Conclusions: We conclude that the most significant finding of this survey is that the diet composition, rather than energy consumption, was the main factor responsible for obesity in both young men and women. Our results suggest that a diet higher in fat and lower in carbohydrates, independent of total energy intake, may contribute to obesity in adolescents.

A study was performed on the breakfast habits of 200 schoolchildren between 9 and 13 years of age. The subjects were classified into two groups: group C, children who consumed fortified breakfast cereals (65 boys and 35 girls), and group NC, children who did not (64 boys and 36 girls). The different dietary habits and the nutritional status of the two groups were analyzed. Haematological, biochemical, anthropometric, and dietary data were collected, the latter involving a 5-day food record. The children of the C group were found not only to have a more complete and nutritive breakfast, but also showed better dietary patterns for the rest of the day. Their lipid intake (% kJ) was lower and the carbohydrate intake (g/d and % kJ) higher than in the NC children. The intakes of thiamine, pyridoxine, folates, and beta-carotenes were also higher in group C. Better dietary habits were reflected in higher blood levels of some important compounds. Group C children had higher retinol, serum folate, and riboflavin levels than NC children. The percentage of children with hypercholesterolaemia (serum cholesterol > 4.5 mmol/l) was higher amongst those of the NC group: 37% as compared with 18% of the C children.

An investigation was made into the breakfast habits of 150 elderly people between 65 and 95 years of age. The food intake of 58 institutionalized subjects was followed by means of "precise individual weighing of food". The food intake of 92 subjects living independently was followed using a prospective method involving the keeping of a "weighed food record". For all subjects the study lasted 5 consecutive days including a Sunday. Institutionalized subjects spent more time at breakfast (p < 0.01 in women) and the food they consumed was more varied, both in terms of number of foods (p < 0.001) and food groups (p < 0.001). Their breakfasts included more fruit (P < 0.001), fibre (P < 0.05 in women) and vitamin A (P < 0.01) than those of independent subjects, 7% of whom took no breakfast at all with a further 8% consuming only a glass of milk or fruit juice. 62.7% of independent and 43.1% of institutionalized subjects consumed an inadequate breakfast (i.e. their breakfasts provided less than 20% of their energy expenditure). The breakfasts of institutionalized subjects contained a greater percentage of their total daily intake of carbohydrates (P < 0.001 in women), fibre (P < 0.01 in women), thiamine (p < 0.05 in women), vitamin B12 (p < 0.05 in women, p < 0.001 in men), vitamin D (p < 0.01 in women) and magnesium (p < 0.05 in women). Given the importance of breakfast in the maintenance of a satisfactory nutritive condition, these results suggest that both qualitative and quantitative improvements of elderly people's breakfasts are required. Residing at an old people's home seems to improve the quality of breakfast consumed, especially for elderly women.

Dietary patterns were studied in 122 Spanish elderly people divided into two groups: overweight/obese subjects (O) (BMI > or = 25 kg/m2), and normal-weight subjects (NW) (BMI < 25). O subjects ate less fruit and more meat than NW subjects. No differences were found between NW and O subjects with respect to energy intake, but O elderly obtained more of their energy from proteins and less from carbohydrates. Further, O subjects showed a higher cholesterol intake per MJ than NW subjects. The existence of the dietary imbalances seen in the diet of the O elderly may damage their health.
