Opis:: Four new symmetrical Schiff bases derived from 2,2’-diamino-4,4’-dimethyl-1,1’-biphenyl-salicylaldehyde have been synthesized and characterized by elemental analysis and different spectroscopic techniques. The reaction of 2,2’-diamino-4,4’-dimethyl-1,1’-biphenyl with two equivalents of 5-tert-butyl-, 3,5-dinitro-, 3,5-dibromo- and 3-tert-butyl-salicylaldehyde yielded 2,2’-bis(5-tert-butyl-salicylideneamino)-4,4’-dimethyl-1,1’-biphenyl (A1) as well as the 3,5-dinitro- (A2), 3,5-dibromo- (A3) and 3-tert-butyl- (A4) substituted derivatives. The tetradentate ligands were then reacted with copper-, manganese- and zinc-acetate producing the tetra-coordinate metal complexes which were characterized by FTIR, UV-Visible spectroscopy, magnetic susceptibility and elemental analysis. Zinc complexes were characterized by 1H-NMR spectroscopy. Density functional theory (DFT) calculations at the B3LYP/6-31G(d) level of theory were carried out to fully optimize and examine the molecular geometries of complexes. Subsequently, IR vibrational and UV-Vis absorption spectra were computed and correlated with the observed values and the results are in good agreement with the experimental data. The anticancerous and antiproliferative activity of the A3 ligand and its metal complexes were determined.

Opis:: Background. The locations of food purchase have an impact on the quality of food consumed. Objective. To examine food purchasing habits at traditional and modern markets, their associated factors, and their effects on consuming natural and processed foods. Material and methods. This work used a validated conceptual and methodological framework of a study conducted among 507 households in the Rabat-Salé-Kenitra region in Morocco. Data on sociodemographic and economic characteristics and the frequency of food purchasing were collected from household representatives through a population survey. The food frequency questionnaire was used to collect frequency of consumption of 20 foods, including 10 natural and 10 processed. The associations between the variables were studied by the Chi-square test with a level of significance of p<0.05. Results. Among the households 70% were urban, 62% have nuclear families, 51.5% a size of 5 to 12 members, 41% middle standard of living, 87% frequented markets and souks (MS), and 19% frequented large and medium-sized stores (LMS) at least once a week. The households have in majority a frequency of natural foods consumption ≥ 3 times/week, including fresh vegetables (91%), olive oil (85%), and fresh fruit (84%); and processed foods, such as refined flours (68%), industrial cheese (65%) and industrial yoghurt (52%). MS and LMS frequentation were associated with environment (p<0.001), family type (p=0.01 and p=0.002, respectively), household size (p=0.04 and p=0.002 respectively) and standard of living (p<0.001). Foods whose consumption was associated with both MS and LMS frequentation included fresh vegetables (p<0.001) as natural foods and baked goods as processed foods (respectively, p=0.01 and p=0.04). Conclusion. The results of this study argue for implementing a nutrition education strategy based on the choice of food purchase locations as well as the consumption of natural or processed foods as part of a sustainable Mediterranean diet.

Opis:: Background. In recent decades, the Moroccan population has changed its dietary practices, particularly those related to meal-taking. It is about irregular meal schedules, reduced frequency and shorter time of meal-taking times, as well as a decrease in family meal-taking. All these factors are likely to influence its nutritional status. Objective. The aim is to study meal-taking practices, their determinants and their implications on weight status. In this study, meal-taking practices are defined by the regularity of the schedule, the frequency and the duration of the meals as well as the family commensality. Material and Methods. This work data are part of a study conducted among 507 households in the region of Rabat-Salé- Kenitra in Morocco, with a validated conceptual and methodological framework. The questionnaire was completed with one member of each household and the body mass index (BMI) was determined by an impedance meter. Results. The main results indicate that the majority of the surveyed population was aged 35 years (59%), female (52%), urban (70%), with a BMI ≥25 kg/m2 (51%), took usually three meals a day (89%), spent less than 90 minutes a day in meals and snacks (60%), had irregular meal schedule (69%), and usually eat at least two meals or snacks a day with family (49%). The univariate analysis showed that urban area was a factor favoring variations of meal times, the male sex was a factor favoring three meals a day, the level of higher education was a factor penalizing the daily duration of meals, and that marital status “married” was a factor favoring family commensality. In addition, variable meal times were revealed as a factor contributing to overweight/obesity, and meal times ≥90 min were revealed as a protective factor of overweight/ obesity. Conclusion. The study identified factors associated with meal times, frequency and duration. The results obtained will serve as a basis for the development of educational actions for a change in behavior conducive to health.

Opis:: Background. Micronutrient malnutrition is a serious public health problem in most developing countries, including Morocco, due to poor and therefore lower quality diets that lack dietary diversity. Objective. The present study aimed to assess dietary diversity and variety and their relationship with micronutrient adequacy in children and adolescents with type 1 diabetes (T1D). Materials and methods. A cross-sectional study was carried among 240 children and adolescents with T1D. Weight and height were measured and BMI was calculated. Dietary intake data were obtained from two 24-h recalls. A Dietary diversity (DDS) and dietary variety scores (DVS) and mean adequacy ratio (MAR) and nutritional adequacy ratios (NARs) were calculated and compared according to sociodemographic/anthropometric categories. Results. 52.1% of the patients were female. The mean age of the patients was 8.49 ± 4.1 years. The mean BMI was 19.44 ± 5.24 kg/m2; the mean DDS was 4.62±1.20 and the mean MAR was 0.66 ± 0.11. Older children living in rural areas have a low DDS/DVS. Parental education and income level are associated with DDS/DVS. General and central obesity were significantly elevated in children with high DDS. In addition, a high intake of vegetables, eggs, fiber and micronutrients (Magnesium, Calcium, Potassium, Zinc, Phosphorus and Vit B1) is associated with a high DDS; however, high DVS is associated with high consumption of dairy products, carbohydrates and low intake of protein and fat. There are also positive correlations between DDS/DVS and NARs for various nutrients. Conclusion. The quality of the respondents’ diets are moderately diversified. DDS or DVS can be used as indicators of micronutrient adequacy in Moroccan T1D children. Nutritional education needs to be strengthened to improve dietary diversity in children, especially in rural areas.

Opis:: Background. Currently, T1D is one of the most common chronic diseases in children and adolescents. The International Diabetes Federation (IDF) estimates that more than 1.1 million children and adolescents are living with (T1D). A few studies have evaluated the relationship between dietary intake and glycemic control (GC) in people with T1D, and in particular, children and adolescents. Objective. The aim of this study was to evaluate the relationship between anthropometric characteristics, lipid profile, inflammation, dietary intake and GC in comparison with international guidelines. Materials and methods. The study included a sample of 240 children, aged 15 years old or less with T1D. A structured questionnaire was used to collect information on the socio-demographic status, disease characteristics, and diet of the participants. Weight, height, and WC were measured and WHtR and BMI were calculated. Biochemical measurements were determined. Dietary intake was assessed using three 24-hour recalls. Results. Saturated fat intake was five times higher than recommended. Only 8.3% of participants reached the recommended level of fiber. Overweight, obesity, TC, TG, HDL and CRP were significantly higher in children with poor GC to those with good GC. In addition, participants with poor GC had significantly low intakes of calories, carbohydrates, fiber, MUFAs, and PUFAs and high intakes of fat and SFAs. The use of Bivariate correlation analyses showed that calorie, protein, fat and fiber intake were positively correlated with weight, height, WC, and GO, whereas carbohydrate intake was negatively associated with these parameters. On the contrary, CO showed a negative correlation with calorie, protein, fat and fiber intake and a positive correlation with carbohydrate intake. Conclusions. The results revealed that the dietary quality was poor and adherence to dietary recommendations was low with insufficient fiber intake and excess SFA. These results suggest that GC can be improved by a healthy, balanced diet by increasing fiber intake and limiting SFA intake.

Opis:: Background. Low birth weight (LBW) is a major health problem responsible for neonatal mortality and morbidity such as diabetes, obesity and cardiovascular disease in adulthood. Objective. This case-control study aims to compare data on the intake of energy, macro and micronutrient in two groups of pregnant women, who gave birth to low birth weight (LBW) babies named cases and those who gave birth to babies of normal weight (NW) called controls. Material and methods. The collection of information was done using an established questionnaire for 400 pregnant women, allowing the collection of data on socio-demographic and obstetrical factors. Nutritional intake was obtained by recording food consumption using the 24-hour recall method. Anthropometric measurements of parturient and fundal height (FH) were measured before delivery. Results. The mean FH of the cases was 25.69±0.13 and that of the controls was 31.83±0.06. The gestational age of the cases was on average 31.65±0.21 week of amenorrhea (WA) against 38.04±0.08 WA for the controls. 37% of LBW newborns had an Apgar score < 7 (p< 0.001) and 71% were hospitalized in neonatal intensive care (p<0.001). Micronutrient deficiency was raised and concerned calcium 34.02% vs 60.65%, folates 48.32% vs 68.01% and iron 50.85% vs 66% in cases and controls respectively. Newborns from NW had a weight of 3395.5±15.99 against 1957.25±30.72 for those from LBW. Conclusion. This study shows that the nutritional intake did not cover all the nutrient needs of the pregnant women studied and that newborns with LBW are associated with an altered anthropometric status. Improving the living conditions of mothers, good monitoring of pregnancy, and good nutritional education can significantly improve the nutritional status with the same food intake and should be integrated into the nutritional intervention strategies.

Opis:: Background. Low birth weight (LBW) is considered to be one of the most important indicators of a newborn's chances of survival, and a major risk of medium- and long-term morbidity. Objective. To identify risk factors associated with low birth weight newborns among pregnant women during childbirth in Moroccan hospital environment with a view to proposing avenues of intervention for its prevention. Material and methods. Data concerning the weight of newborns at birth, nutritional education, pregnancy monitoring and other risk factors, etc. were collected from 312 pregnant women who gave birth in the maternity ward of El-Jadida Provincial Hospital in Morocco. Results. The study identified 156 cases of newborns with LBW and 156 controls of normal-weight newborns. After adjustment for the variables included in the analysis, the determined factors associated with LBW are nutritional education [OR: 6.22 (2.60-14.87), P<0.001], illiterate women [OR: 8.74 (1.65-46.08), P=0.011], insufficient pregnancy monitoring [OR: 5.69 (2.74-11.83),P<0.001], pregnant women with a normal weight [OR: 3.84 (1.73-8.52), P=0.001], lack of psychological support [OR: 3.23 (1.72-6.08), P<0.001] and tiring domestic activity [OR: 2.13 (1.14-3.99), P=0.017]. Conclusion. Promotion of nutrition for pregnant women, proper implementation of maternal health programs and improvement of their social condition are the modifiable factors that should help reduce LBW risk.

Opis:: Background. Low birth weight (LBW) is an important predictor of neonatal morbidity and mortality. It reflects the nutritional status of the mother and the quality of health care services during pregnancy. Objective. The objective of this study is to determine the factors associated with low birth weight of children born to Moroccan pregnant women in the province of El Jadida. Material and Methods. This cross-sectional case-control study was carried out in the maternity ward of El Jadida provincial hospital on 344 parturient women, half of whom had given birth to children with an LBW and the other half of children with normal weight (NW) at birth. Information on maternal gestational and socioeconomic characteristics as well as eating habits was collected using a questionnaire and anthropometric measurements were taken on the newborns. Results. The study identified 172 parturient who gave birth to newborns with LBW and 172 parturient who gave birth to newborns of NW. The proportions of LBW are greater in first-time mothers (50.6%) and professionally inactive (86.6%). The mean weight of LBW newborns is 2013.95 ± 372.95g compared to 3380 ± 217.59g for NW newborns. The determined factors associated with LBW are the low socio-economic level (OR = 3.18; 95% CI: 1.09-9.23), insufficient monitoring of prenatal consultation (OR = 2.91; 95% CI: 1, 71-4.95), origin from rural areas (OR = 0.52; 95% CI: 0.30-0.91) and lack of nutritional education (OR = 0.17; 95% CI: 0, 09-0.34). The daily calcium intake in mothers of newborns with LBW is 33.82% of the recommended daily allowance (RDA), the daily iron requirement coverage was 50%, folates 66, 16% and zinc 87.72% of the RDA. Conclusions. Well-targeted and coordinated education and awareness-raising actions on early pregnancy and feeding pregnant women could have a positive impact on improving the birth rate of children with a weight deficit.

Opis:: 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.
