The epidemiologic studies from the recent years indicate that high consumption of foods rich in bioactive compounds has a positive effect on human health and could diminish the risk of numerous diseases, such as cancer, heart disease, stroke, Alzheimer's disease, diabetes, cataracts, and even diseases related to age. From all species of fruit, definitely consumption of berries due to its high content of bioactive constituents prevents the risk of cardiovascular disease, oxidative stress and diabetes. The primary phenolic compounds in berries are flavonoids, particularly the anthocyanins. They have potential preventative and therapeutic effects on many diseases such as cancers, inflammation and cardiovascular diseases, obesity, neurodegenerative pathologies, and muscular degeneration. Bilberry fruits have been an important part of local diets in many countries, including Slovakia. They are valued for their pleasant taste and aroma and are often processed into jams, preserves, juices, and alcoholic beverages. In the last two decades, the Saskatoon berry has been cultivated in many parts of the world for its suitability for various food products and due to its high content of nutrients and polyphenols. Cardiovascular disease (CVD) remains the world's leading cause of morbidity and mortality. Dyslipidemia, which results from one or more abnormalities of blood lipids metabolism, remains a major key factor for progression of CVD and leads to the development of atherosclerotic plaques. The aim of this review is to compare and summarize the research evidence on the potential of bilberries and saskatoon berries with an emphasis on recent studies in humans in improving cardiovascular risk factors especially dyslipidemia.

Background: The formation and development of the metabolic syndrome (MetS) is largely caused by lifestyle factors. Many studies have shown that excessive consumption of simple carbohydrates, alcohol, salt, physical inactivity and smoking increase the risk of MetS.

Objective: The aim of the study was to assess the nutritional status and its relationship with selected lifestyle factors in elderly people with MetS.

Material and methods: 81 people aged 51-75 participated in the study. According to the guidelines, all tests were performed on an empty stomach. The comparison of individual quantitative variables between the groups was performed using the Student's t-test for independent measurements or using the Mann-Whitney U test. The relationship between quantitative variables was verified with the Spearman's correlation coefficient. All statistical tests were based on a significance level of p<0.05.

Results: The BMI, the percentage of body fat and the waist circumference significantly exceed the norm for the population in the examined persons. The responses of respondents aged 51-65 show that 36% of people sweetened their drinks, 65.6% were salted their food, 51.6% consumed alcohol, and at the age of 66-75, respectively: 47.1%, 52.9%, 41.2%. There was no correlation between sweetening beverages and salting food and the concentration of glucose and lipids. However, a positive correlation was found between the amount of salt consumed and the heart rate (r=0.28, pp<0.05). In both age groups, statistically significant differences in the concentration of triglycerides depending on alcohol consumption or non-consumption were found. Due to the lack of precise data on the amount of alcohol consumed, the correlation between alcohol consumption and the concentration of glucose and lipids was not analyzed. Physical activity was not undertaken by 39.1% of patients aged 51-65 years and 41.2% of patients aged 66-75 years. In the group of elderly people without physical activity, a statistically significantly higher glucose concentration was found in relation to those who were physically active (130 mg/dl vs. 105 mg/dl; p=0.031). Patients aged 51-65 who engaged physical activity had statistically significantly lower body weight, BMI, waist circumference and lean body mass, which requires further studies.

Conclusions: The anthropometric indices and parameters of MetS patients indicated disturbances in the nutritional status. Unhealthy lifestyle was shown mainly in the younger group of patients 51-65 years old (they sweetened drinks more often, salted dishes, consumed alcohol). Patients with metabolic syndrome did not undertake physical activity as often as recommended.

Background: In Morocco, fava beans are widely used as a main meal or as an ingredient in various traditional recipes, in the form of fresh ripe seeds or dry seeds. In the past, the tender skin of bean pods was also used in certain specific dishes, thus diversifying the diet. However, the peels of the tender bean pods are currently less or not used and considered waste. In Moroccan, fava bean pods peels, traditionally used in food in the past, are today considered as waste. The valorization of fresh fava bean pods could revitalize the use of the specific dishes and diversify the diet. For this reason, the research aimed to assess the nutritional values and biological compounds of the whole fresh fava bean pods (Vicia faba L.).

Objective: Evaluate the content of nutrients, total phenolic, flavonoids and tannin contents and antioxidant activity in different extracts of the tender pods of the fava bean (Vicia faba L.).

Material and methods: The proximate composition and minerals were determined using AOAC methods. The total phenolic compounds by the Folin-Ciocalteu reagent, the total flavonoids were analyzed using aluminum chloride colorimetric method, the tannins by method of vanillin in an acidic medium and the antioxidant activity was evaluated by DPPH method.

Results: The results show that the fresh fava bean pods have a moisture content of 87.31 ± 0.25%, ash 4.67 ± 1.03, and protein 29.11 ± 3.20 g/100 g. The legume samples also contain potassium (1946.8±4.61), phosphorus (483.8 ± 3.14), and calcium (399.6 ±2.25) mg/100 g of dry matter representing at last 40-50% of the RDI. The content of the different extracts of (Vicia faba L) varied from 49.5 to 594.4 mg GAE/ g for the total phenols, from 0.7 mg to 3.4 mg QE/g for flavonoids, and from 4.9 mg to 73.91 mg TAE/g dry weight for tannins. The evaluation of the antioxidant activity in the various extracts revealed a better activity in the methanolic extract (IC50=491.2 μg/mL) compared to others extracts: the MeOH/water extract (IC50=606.61 μg/mL), DCM/ MeOH extract (IC50 = 642.67 μg/mL) and DCM extract below of 50%.

Conclusions: This study shows that fava bean pods, traditionally used in food, are rich in macro and micronutrients and bioactive substances, which demonstrates their potential contribution to human food and nutritional security.

The Position Statement on the principles of nutrition for children aged 1-3 years emphasizes that proper nutrition of children at this age determines their optimal psychometric development and has beneficial effects on the process nutritional programming, which reduces the risk of diet-related diseases in adulthood. Continued breastfeeding in the post-infancy period, together with the proper introduction of complementary foods, supplies all the nutritional needs of the child. A varied selection of food products is important to balance out the diet of a child in the context of energy and nutrient needs. Attention should be paid to products not recommended for frequent consumption, due to the possibility of the early development of improper eating habits that can lead to undesirable health consequences. Due to the potential risk of deficiency, adequate intake of iron, iodine, calcium and vitamin D, as well as of n-3 PUFAs (which is often insufficient) should be provided. Adequate dietary energy and protein intake protects children against protein-energy undernutrition and is crucial for their proper growth and development. An important element in the assessment of the development of children involves monitoring their nutritional status and physical development by systematically measuring their body weight and length/height and analyzing their weight gain. It is necessary to diagnose the causes of being underweight/overweight in children. Physical activity (such as outdoor walks, plays, and games) and healthy sleep hygiene are recommended. Physical activity, an adequate number of hours of sleep, and the quality of sleep in early childhood may improve immunity, reduce the risk of excessive weight gain, and consequently reduce the risk of obesity later in life. Other issues discussed include the functioning of the digestive system as one of the determinants of the nutrition of young children, basics of proper nutrition, risk of nutrient deficiencies and development of proper eating habits in early childhood.

Background: Despite the efforts of health systems, the prevalence of malnutrition reflected by weight status still poses challenges for many countries around the world. In fact, with the decrease in undernutrition, excess weight and obesity are gradually increasing in parallel with that of chronic diseases. Among school-going adolescents, however, weight status is less studied, particularly in developing countries.

Objective: The objective of this research is to examine the situation and the determinants of the weight status of adolescents in the province of El Jadida in Morocco.

Material and methods: The study was carried out on a sample of 463 students from the province of El Jadida of which 58.1% are boys and 41.9% girls, ages 9 and 17. Nutritional status was assessed by anthropometric measurements including height, weight and waist and hip circumference. Body mass index (BMI) was calculated to determine underweight, overweight and general obesity and waist circumference and the waist circumference to hip circumference ratio were used to determine abdominal obesity.

Results: The results indicate that only 59.6% of students had normal weight status, 40.4% had abnormal BMI values corresponding to thinness in 18.8% and overweight (overweight and obesity) in 21.6%. A significant difference in the prevalence of abnormal weight status by sex and level of physical activity was found. The results of the present study reveal an abnormal weight status in a large proportion of adolescents linked in addition to the peculiarities of the puberty phase to the sedentary lifestyle in the study population.

Conclusions: The results obtained revealed the coexistence of over-nutrition and undernutrition which require a prevention policy based on regular monitoring of weight status as well as on nutritional education and the promotion of physical activity for children and parents.

Background: The Thai government has been developing its Eastern Economic Corridor (EEC), which spans three provinces, with the aim of improving connections with other Asian nations. Since this strategic development, the number of trucks, private car, and passenger car registrations have continued to grow, with a corresponding increase in related to benzene, toluene, ethylbenzene, and xylene (BTEX).

Objectives: This study aims to compare the levels of trans, trans-muconic acid (t, t MA); toluene (TU); mandelic acid (MA); and methyl hippuric acid (MHA) in the urine of gas station employees, considering demographic and occupational factors.

Material and methods: These employees worked either near or away from the fuel dispenser, and there 100 people in each group. Data were collected using interviews and testing environmental air and urine samples for benzene, toluene, ethyl benzene, and xylene (BTEX).

Results: The results showed that BTEX concentrations were just detectable in all 200 cases (100%). The mean (±SD) urine level of t, t MA was 449.28 (±213.32) μg/g creatinine, while the median (min-max) was 428.23 (95.58-1202.56) μg/g creatinine. The mean TU was 0.011 (0.001) mg/L, while the median (min-max) was 0.011 (0.010-0.013) mg/L. MA levels were higher inside the pollution control zone than they were outside the zone (p=.009). Employees who practiced poor personal hygiene had relatively high urinary toluene and MHA levels (p=.009) and those who did not wear personal protective equipment (PPE) had relatively high MA levels (p=.040).

Conclusion: The results of this study revealed statistically significant biomarkers influencing the levels of t, t MA; TU; MA; and MHA in urine. The recommendations of this study are that employers should provide their employees with suitable PPE, check regularly to ensure that it is worn, and strongly encourage employees to take care of their sanitation. Employees should take appropriate breaks and days off to minimize their exposure to BTEX.

Background: Petrol station (PS) workers are categorized as "unskilled labor", which leads to low wages, economic instability, and a lack of adequate access to healthcare services (HCS) despite exposure to dangerous chemicals. A lack of information on the HCS access of PS workers is concerning.

Objective: This study was undertaken to elucidate factors that influenced access to health care for fuel station workers in gas stations in Rayong province, Thailand.

Material and methods: Two-hundred PS workers (100 serving at fuel dispensers and 100 working at other locations) were interviewed to evaluate their health conditions and factors affecting HCS access. The study cohort comprised 137 (68.5%) women and 63 (31.5%) men. The mean age was 30.29±10.97 years and the average monthly salary was 341.16 ± 124.72 USD.

Results: The average distance between a respondent's residence and government hospital was 10.49 ± 8.571 km. Most respondents (63.5%) were in good physical health, and 79.5% reported having "positive mental health". However, 73% reported neurological disorders and 57% reported respiratory symptoms. During the previous 12 months, 44.5% of respondents had HCS access; 80.9% of participants reported that they had accessed HCS to obtain treatment for an illness, and 18% went for a health checkup. Government centers were rated as "satisfactory" by 78.8% of PS workers, and 75.5% received medical coverage under a social-security scheme. Moreover, 38.5% obtained HC information from their colleagues. HCS access was attributed to the cost of receiving HCS as well as the sex, marital status, illness severity of PS workers.

Conclusions: Workers should have access to comprehensive HCS. Policy frameworks and systems for HCS should take account of employees' sex, marital status, and the type and severity of their illnesses.

Background: The use of validated and reliable methods and instruments is necessary to study dietary practices and nutritional status due to their direct impacts on population health.

Objective: The aim is the validity and reliability of the conceptual and methodological framework of research on factors associated with dietary practices and nutritional status (FADPNS), carried out on adult population of the Rabat-Salé-Kenitra region in Morocco.

Material and methods: First, we developed a conceptual and methodological framework for research on FADPNS, which aimed to study dietary practices, nutritional status, and the factors associated with them in an adult Moroccan population. Then, we studied the validity and reliability of this framework in three phases. Phase 1 focused on the validation of the content of the conceptual and methodological framework, Phase 2 focused on the study by an expert committee of the internal consistency validity (ICV) of the questionnaires used in this research , and Phase 3 consisted of the study of the reliability of the items questionnaires by the test of Cronbach Alpha.

Results: Thus, the validated content of the conceptual framework of research on FADPNS includes socio-demographic, socio-economic, and socio-cultural characteristics; health status; physical activity, places of food purchase; food preparation, taking of meals, family commensality; social representations of good dietary practices; food consumption; and nutritional status. The questionnaires used in this research received an ICV score of 85%. The reliability test of the questionnaires showed a Cronbach Alpha value ≥ 0.5, which turned out to vary from "moderate" to "excellent".

Conclusion: This work enabled the validation of the conceptual framework and the methodology of the study of the factors associated with dietary practices and nutritional status in the RSK region.

Background: During the COVID-19 pandemic, concerns were raised about the lack of knowledge and awareness of health workers (HW) in hampering the implementation of COVID-19 preventive strategies in hospitals.

Objective: This cross-sectional study aims to explore the knowledge, attitudes, and practices (KAP) of the health workers related to COVID-19 in Moroccan hospitals and health facilities.

Materials and methods: We administered an adapted questionnaire to 242 HW working in Azemmour and El Jadida hospital (two sites) and in 41 health centers in El Jadida province. We carried out a bivariate analysis and used contingency tables and logistic regression models to identify factors associated with different KAP levels.

Results: We found that 90.1%, 8.3% and 60.3% of HW had respectively high levels of knowledge, risk perception attitudes and preventive practices towards COVID-19. High level of knowledge was associated with gender (OR: 0.267; 95% CI: 0.113-0.634; p=0.002), and professional profile (p<0.001). Levels of attitudes were associated with gender (OR: 17.143; 95% CI: 5.450-53.932; p<0.001) whereas levels of preventive practices were associated with position of the HW in COVID-19 (frontline or not frontline) (OR: 0.404; 95% CI: 0.236-0.691; p=0.001) and the overworked status of the HW (OR: 0.421; 95% CI: 0.242-0.730; p=0.002).

Conclusion: Professionals' knowledge and practice levels were higher than their COVID-19 risk perception attitudes. Therefore, efforts should be made to improve the attitudes of health professionals.

Background: Dietary diversity and variety scores represent tools for measuring the overall quality of diets. In children, they are good indicators of their nutritional status and growth.

Objective: The aim of this study was to assess the consumption and eating habits as well as the lifestyle of Moroccan adolescents attending school in the city of El Jadida.

Material and methods: A sample of 463 children of both sexes, aged 9 to 17, attending four schools in the city of El Jadida was studied. Eating habits and information on socioeconomic level are assessed using questionnaires and weight and height were measured on participants.

Results: According to the dietary diversity score (DDS) classes, 2.4% of the children surveyed were with low DDS, 55.7% moderate and 41.9%, with high DDS. The mean DDS was 5.67 ± 1.03 in underweight children and 5.53 ± 1.5 in those with overweight (obesity included) and the food variety scores (DVS) were of 12.94±3.24 food items and 10.81±3.25 in the 2 groups respectively. In addition, data analyzes show that children from parents with a low level of education had higher averages of DDS and DVS (DDS: 5.54 ± 0.84; SVA: 10.65 ± 2.32) compared to those of parents with medium education level (DDS: 5.31±0.96; DVS: 9.72±2.62) or high level (DDS: 5.17±0.93; DVS: 9.36 ±2.42). In addition, children from parents of high economic level had a lower averages of DDS and DVS (DDS: 5.24 ± 0.88; DVS: 8.84 ± 2.10) compared to those of parents of low economic level (DDS: 5.36±1.00; DVS: 10.14±2.85). The sugary products were consumed by 56.3% of underweiht children, 75% of normal-weight children and 67% of overweight children (including obese). The estimated total energy intake (TEI) was higher than the Recommended Daily Allowances (RDA) in underweight 2933 Kcal/d and in overweight (including obese) children 3061.75 Kcal/d, while the mean daily intakes of folate, calcium, iron, potassium and zinc were lower than the (RDA). The food groups consumed by the majority of children were cereals (98.5%), fruits and vegetables (87.7%), and sweet products (69.8%) while oilseed products and fat were less consumed (9.7% and 7.8% respectively).

Conclusion: The study data show that the adolescents diet were moderately diverse, little varied and poor in certain nutrients essential for their nutritional status and growth. The study draws attention to the need for parents to be aware of the benefits of improving the diet quality and weight status of adolescents.
