Nutrition knowledge, attitudes, and good practices are essential for preventing malnutrition, ensuring good health, and maintaining life quality. However, to the best of our knowledge, no studies have been published on the nutritional knowledge, attitudes, and practices (KAPs) of Jordanian older people. For this reason, our study aimed to assess the KAPs in the Jordanian elderly. A cross-sectional survey was conducted among 1200 people aged 60 and over. The results revealed that 52.8% of participants had poor knowledge, 52.7% had negative attitude scores, and 72.6% had poor practices. Significant differences were found between the three regions in the KAP prevalence (p < 0.001). The northern region had a higher prevalence of nutritionally poor knowledge (65.6%) compared to 52.5% and 40.4% for the central and southern regions, respectively. Participants from the central region had a higher prevalence of a positive attitude (55.4%), whereas the northern and the southern participants had a higher prevalence of a negative attitude (65.6% and 54.4%, respectively). All regions reported poor practices, yet, significantly, the northern regions had the highest prevalence of poor practices. Participants with a low educational level reported a significantly higher prevalence of poor knowledge, negative attitudes, and poor practices compared to participants with a high educational level. The results obtained underline the importance of taking into account the lack of nutrition-related KAPs among the elderly in Jordan. It is crucial to raise awareness on this issue and to implement the national nutrition strategy, with particular attention paid to the elderly. Concrete measures must be taken to ensure that the nutritional needs of older people are met and to improve their quality of life.

Insufficient physical activity is considered a strong risk factor associated with non-communicable diseases. This study aimed to assess the impact of COVID-19 on physical (in)activity behavior in 10 Arab countries before and during the lockdown. A cross-sectional study using a validated online survey was launched originally in 38 different countries. The Eastern Mediterranean regional data related to the 10 Arabic countries that participated in the survey were selected for analysis in this study. A total of 12,433 participants were included in this analysis. The mean age of the participants was 30.3 (SD, 11.7) years. Descriptive and regression analyses were conducted to examine the associations between physical activity levels and the participants’ sociodemographic characteristics, watching TV, screen time, and computer usage. Physical activity levels decreased significantly during the lockdown. Participants’ country of origin, gender, and education were associated with physical activity before and during the lockdown (p < 0.050). Older age, watching TV, and using computers had a negative effect on physical activity before and during the lockdown (p < 0.050). Strategies to improve physical activity and minimize sedentary behavior should be implemented, as well as to reduce unhealthy levels of inactive time, especially during times of crisis. Further research on the influence of a lack of physical activity on overall health status, as well as on the COVID-19 disease effect is recommended.

Aim: This study aimed to determine the current stage of change (SOG) toward seven healthy eating behaviors and two healthy lifestyle behaviors related to blood pressure (BP) control. The lifestyle behaviors included smoking Behavior and practicing regular exercise, while the dietary behaviors included the DASH diet guidelines. Methods: A total of 1109 outpatients participated in this cross-sectional study that was conducted between 2021 and 2022 in Jordan. A staging algorithm assessed SOG for several BP control-related behaviors for diagnosed hypertension patients. Data were collected by a structured interview-based questionnaire. Results: There was a high degree of maintenance toward consuming diets with high grains, fruit, vegetables, meat, and poultry, less saturated fat, and more low-fat dairy products. More than half of the participants were in the pre-action stage for quitting smoking, practicing physical exercise, and consuming sweets and added sugars. Significant associations were observed between the degree of maintenance for several behaviors (p < 0.01). Age, income, education level, disease duration, and nutrition consultation availability were the most related factors to the SOG of the studied behaviors (p < 0.01). Conclusion: Patients with hypertension in Jordan are still in the pre-action stages for quitting smoking, practicing physical exercise, and consuming 5 servings of refined sweets and added sugars weekly. The current outcome suggests a need for nutritional counseling, education, and interventions to raise awareness of lifestyle factors influencing BP among hypertension patients.

Background: Turkish coffee (TC), a traditional unfiltered coffee preparation method, contains unique bioactive compounds due to its specific brewing process. While TC’s cultural significance is well-documented, its acute physiological and psychological effects remain understudied. Objectives: This randomized, controlled crossover trial investigated the acute effects of a standardized TC dose (3 mg caffeine/kg body weight) on metabolic and psychological parameters in healthy female university students (n = 52, age: 20.25 ± 1.20 years). Methods: TC was prepared with a 1:1 ratio of medium and dark roasted Arabica beans. The chemical analysis showed the caffeine content to be 2.8 ± 0.3 mg/mL and the chlorogenic acid content to be 1.9 ± 0.2 mg/ml. Participants were randomized to receive either TC or water control, with a washout period of 8 weeks between treatments. Cardiovascular parameters, metabolic markers, and validated visual analog scales (VAS) were assessed at baseline, 60-, 90-, and 120-min post-consumption. Results: Heart rate showed significant time-dependent reductions in both groups (control: p < 0.05; TC: p-value < 0.01 at 60, 90, and 120 min vs. baseline). Heart rate dropped significantly in the Turkish coffee group, from 78.0 ± 10.2 bpm at baseline to 71.5 ± 9.5 bpm after 90 min (p-value = 0.002). Sleep scores also declined, from 4.38 ± 2.91 at baseline to 1.88 ± 1.45 after 120 min (p < 0.05), indicating a stimulating effect of caffeine. TC consumption significantly affected appetite sensations (p < 0.05) and sleep scores (F = 3.174, p-value = 0.029), with the TC group showing progressive reductions in sleep scores from baseline (4.38 ± 2.91) to 60 min (2.58 ± 2.04), and further decreases at 90 and 120 min. Conclusions: These findings suggest that TC exerts significant acute effects on cardiovascular function and psychophysiological parameters in healthy young females, potentially due to its unique phytochemical profile and preparation method.

Major historic olive tree cultivars around the Mediterranean originate from the Jordan area and possess a proven abiotic stress tolerance; however, they were unexplored from the diversity perspective. Therefore, historic olive tree accessions from three northern regions—Irbid (i), Jerash (J), and Ajloun (A)—were analyzed using DNA molecular markers to identify and study their genetic relationships and genetic structure. DNA molecular markers of inter-simple sequence repeats (ISSR) were used. A total of 3150 data entries (859 present and 2291 absent) were generated with fragment sizes ranging from 350 to 2000 bp. Data entries were evaluated with UPGMA and population genetic structure analysis. The results showed that similarity among the investigated sixty-three accessions ranged from 9% between J14 and i20 up to 100% between ‘J11’ and ‘J12’ and between A8 and A9. The discriminating power values for ISSR_807, ISSR_810, and ISSR_825 were 0.70, 0.61, and 0.83, respectively. A generated dendrogram showed ten major clades, while the genetic structure could resolve four unique genetic pools: one for Irbid, one for Jerash, and two for Ajloun. In addition, analysis of 19 phenotypic parameters covering leaf, fruit, stone, and flesh was able to confirm the molecular data. Phenotypic and ISSR data were analyzed using PCA, cluster, and Mantel tests. ISSR markers showed clear genetic differentiation among groups, whereas phenotypic traits displayed lower variation but a significant correlation with molecular diversity. Promising accessions with either pure or admixture genetic makeup were identified. The resolved genetic structure of the investigated historic olive accessions would open new frontiers for olive breeding and utilization, helping to overcome current production challenges and climate change limitations.
