Prevalence and predictors of overweight and obesity among women of childbearing age in the province of Essaouira, Morocco

Low- and middle-income countries are facing a rapid increase in nutritional problems, particularly in Africa, where undernutrition, overweight and micronutrient deficiencies coexist, creating a double burden of malnutrition and a challenge to public health policies. In this context, Morocco stands out for its early nutritional transition, characterized by a moderate prevalence of overweight and undernutrition and elevated levels of micronutrient deficiencies. The aim of this study was to assess the weight status of women of childbearing age and identify its determinants to suggest ways to improve it. The study was conducted in the province of Essaouira in Morocco, which is characterized by a predominance of rural areas and multidimensional poverty. We conducted a quantitative cross-sectional survey of 1,466 married women of childbearing age via stratified random sampling. Data were collected via questionnaires and anthropometric measurements; we applied the WHO curves to classify BMI. Data entry and statistical processing were performed via SPSS® v. 26. The results show that women’s weight status is worrisome, with an average BMI of 26.4 kg/m². The prevalence of overweight was 61.6% (BMI ≥ 25 kg/m2), with 17.9% of women being obese. Bivariate analysis revealed that age, education level, socioprofessional activity, family structure, household income and parity were significantly associated with overweight. Binary logistic regression confirmed that women’s age and level of education are major determinants of overweight/obesity. There is a need to strengthen public health policies aimed at reducing overweight and obesity among women of childbearing age in Morocco, with an emphasis on nutrition education and monitoring their weight status throughout their reproductive lives.

EFFECTS OF TECHNOLOGICAL METHODS OF GROWING DRIP-IRRIGATED WATERMELON FOR SEEDS ON SEED YIELD AND QUALITY

Purpose: To investigate the influence of drip irrigation of watermelon seed plants grown by different technological methods on the seed productivity, yield and sowing qualities. Methods: Field - determination of yield, biometric records and measurements; Laboratory - analyses of seed quality; Mathematical and statistical - ANOVA and statistical processing of data. Results. The optimal time for sowing seeds in drip-irrigated watermelon seed plantations was determined: the beginning of the second 10 days of May. When seeds were sown within the third 10 days of April or May, the yield of watermelon seeds was decreased by 37.8–51.6 kg/ha (16.7–18.5%, first period) and 61.5–69.0 kg/ha (24.3–27.2%, third period). Improved water supply of plants during the growing period due to drip irrigation contributed to an increase in the fruit yield and seed productivity. It was proven that the maximum yields of fruits (41.6 t/ha) and seeds (278.9 kg/ha) were harvested with a 1.4 x 0.35 m sowing scheme, plant density of 20,300 plats/ha, second sowing timeframe, and drip irrigation. The gain in the seed yield compared to the control (10,200 plants/ha) was 29.8 kg/ha (12.0%). It was found that, when watermelon seed plants were drip-irrigated, the yield of seeds was increased by 43.5–73.6 kg/ha (32.8–41.6%) compared to no irrigation variants. When seed plants were sown within the second timeframe according to a 1.4 × 1.05 m sowing scheme, with a smaller number of plants per hectare, the yield of seeds was reduced by 9.2–22.3 kg/ha (9.1%). The highest yield of certified seeds from fruits (91.9–93.8%) was harvested when seeds were sown within in the second timeframe according to any sowing schemes. Discussion. Our obtained are consistent with similar developments of domestic and foreign researchers. The high efficiency of growing watermelon seed plants under drip irrigation was demonstrated. Conclusions. The agrotechnical methods of watermelon seed plant growing, which determine the formation of fruits, their seed productivity, seed yield and quality, were studied. The optimal period for sowing seeds in drip-irrigated seed plantations (second 10 days of May, 1.4 × 0.35 m sowing scheme, and plant density of 20,300 plants/ha) was determined.

Optimization of Coating Process Parameters by Analysis of Target Powder Thickness and Regression Modeling

The development of corrosion mechanisms is a major issue that industrial experts are faced with while dealing with all phases of metal exploitation. Damage caused by corrosion affects the increase in both direct and indirect costs of manufacture. With adequate surface protection technology, it is possible to lessen the intensity of corrosion mechanisms’ development. In order for the selected surface protection technology to provide its full protective action, it is necessary to be familiar with its process parameters. This paper deals with a surface protection system that creates a barrier between the aggressive environment and the base material. The tested barrier was created on a base material surface by electrostatic powder spraying. In this experiment, three types of base material (carbon steel, aluminum and galvanized steel) were coated by applying different combinations of operating parameters. Operating parameters, i.e., the voltage and strength of the electric current, were taken as numerical input variables in the experiment. Each experiment design was focused on measuring the thickness of the protective layer. Analysis of the obtained results and statistical data processing confirmed that appropriate parameters (input variables) provided the target thickness of the protective coating on each of the tested materials. Optimization of parameters contributes to the efficiency of production, shortens the processing time and ensures that coating thickness stays within the limits defined either by the manufacturer or the end user.

Cadmium content in commercial fishes of the Barents Sea (based on long-term data)

The aim: to study the amount of cadmium found in muscle tissue and liver of the main commercial fish species of the Barents Sea.Research material was comprised of fish samples collected during the expeditions of N.M. Knipovich «PINRO» in the Barents Sea in 2009–2021. The study was based on muscle and liver samples taken from cod, haddock, long rough dab, Greenland halibut, plaice and spotted catfish. Over 1500 samples were analyzed.Novelty: for the first time a comparative analysis of Cd concentration in six commercial fish species of the Barents Sea was run and background readings were provided using such a big amount of data.Methods used: the content of Cd in fish samples was measured using Shimadzu (Japan) Atomic Absorption Spectrophotometer (AAS). Statistical data processing and charting were done using MS Excel and application software package of Statistica 13.The results show that the average content of Cd in muscle and liver of the examined fish did not exceed the established sanitary standard for the maximal concentrations of 0.2 and 0.7 mg/kg of wet weight, respectively. No evidence of anthropogenic contamination of the studied species by cadmium was found. The cadmium concentrations in liver was 11–17 times higher than in muscle. The total content of Cd in muscle and liver demonstrated a high variability (dispersion). The main reason for this variability is differences in the diet and feeding habits of the fishes. The cadmium content in muscle tissues is species-specific. The liver is capable of removing Cd from the body actively. The study also found other factors influencing the cadmium concentrations, such as taxonomic affiliation and regional peculiarities (particularly, habitats and fishing areas).Practical significance: the acquired results were used to determine whether the commercial fishes meet the sanitary standards used in Russia.

The Study Purpose was to investigate the effects of silicon-containing fertilizers on the plant growth and development as well as on the performance and fruit quality in nutmeg pumpkin cv. ‘Novynka’ grown by adaptive technology. Methods: field - monitoring of the plant growth and development, agro-meteorological conditions of the environment and other biological and phenological factors; laboratory - determination of quality parameters of seeds and yield; mathematical and statistical - ANOVA and statistical processing of data in order to evaluate the significance of differences, assessments of the economic and bioenergetic efficiency of the cultivation technology. Results. The adaptive and basic technologies for growing nutmeg pumpkin cv. ‘Novynka’ were compared. The effects of root-applied silicon fertilizers on the growth and development of pumpkin plants as well as on the yield and product quality were studied. Conclusions. Based on the results, we concluded that the root application of silicon-containing fertilizers with the underlying recommended dose of mineral fertilizers increased the contents of available mineral nutrients in the soil and significantly improved the conditions for the growth and development of gourd plants, which was confirmed by enlarged leaf surface and enhanced performance of pumpkin plants compared to the recommended fertilization regimen. The root (in-sowing) application of granulated silicon fertilizer on gourds with the underlying recommended dose of mineral fertilizers significantly increased the pumpkin yield by 0.8 t/ha compared to the recommended fertilization regimen. The highest yield from gourds was harvested when the adaptive cultivation technology, which, in addition to the recommended mineral fertilization regimen, included silicon-containing fertilizers for seed priming, in-sowing application and foliar fertilization, was used.

EVALUATION OF FREQUENCY, CLINICAL AND DIAGNOSTIC CHARACTERISTICS OF HEREDITARY RETINAL DYSTROPHY IN CHILDREN

Purpose – to study the frequency, clinical forms and diagnostic features of congenital hereditary retinal dystrophies among children. Materials and methods The object of the study was the database and statistical reporting forms of the Children's Medical Expert Commission of the National Ophthalmology Centre named after Academician Zarifa Aliyeva for the years 2019-2023. Based on the patients’ family history, a statistical analysis was carried out in 2 main groups: Group A consisted of children born from consanguineous marriages (n=409), while Group B comprised children born from non-consanguineous marriages (n=151). Each group was divided into 3 subgroups according to age categories (0-5, 6-10, 11-15). During the study of children diagnosed with hereditary retinal dystrophy, they were analyzed according to family history, and sex-age characteristics. Mathematical processing of statistical data was carried out using SPSS 26 software. To assess the ocular condition, a range of comprehensive ophthalmological examination methods were used, including electroretinography (ERG). The considered diagnoses were classified according to the ICD-10 nosological groups of eye pathology. Results According to the results of our study, retinal dystrophy was observed in 151 patients (27%) out of 560 children with hereditary eye diseases. Among them, 134 patients (89%) had a family history of consanguineous marriage. The clinical manifestations of these diseases were more pronounced in the 6–10-year age group. Retinitis pigmentosa occurred most frequently in children born from consanguineous marriages. The incidence was higher among boys in both groups. Conclusion Our study revealed that among congenital pathologies in children born from consanguineous marriages, there was a high frequency of retinal dystrophies (32.8%). The results indicate that, in addition to the use of modern diagnostic methods, ERG remains the gold standard for detecting this pathology and identifying its clinical manifestations. Key words: consanguineous marriages, hereditary eye diseases, retinal dystrophies

The system of additional education forms professional self-awareness, a sense of self-worth, and promotes the disclosure of personal and leadership potential, which will contribute to successful career building.
