Perceptions, Attitudes, and Barriers towards the Use of Central Board for Accreditation of Healthcare Institutions (CBAHI) Standards among Saudi Healthcare Providers

BACKGROUND

Quality improvement is a strategic priority for all healthcare systems. However, the engagement of healthcare providers in pursuing accreditation plays a critical role in integrating standards into routine practice. Therefore, the current study assessed the perceptions, attitudes, and barriers towards using the Central Board for Accreditation of Healthcare Institutions (CBAHI) standards among Saudi healthcare providers.

METHOD

This cross-sectional study was conducted in 2023 among a representative sample (364) of Saudi healthcare providers (both genders, aged 20-60) working at twenty governmental CBAHI-accredited hospitals in Saudi Arabia. The study participants were selected using a cluster random sampling method. Data regarding the perceptions, attitudes, and barriers toward using CBAHI standards among Saudi healthcare providers were evaluated using a validated questionnaire. Additional information regarding demographic-socioeconomic variables was obtained with an interview-based questionnaire. Statistical analysis was performed using SPSS version 28.

RESULTS

A total of 364 healthcare providers participated in the current study. Of them, 54.4% were males, and 45.6% were females. Almost half (48.6%) of the study participants held bachelor's degrees. For the variables of age group, marital status, monthly income, and years of work experience, statistically significant associations were found between males and females (p-value < 0.05). The means of overall item agreement percentage of the participating healthcare providers for perceptions and attitudes towards using CBAHI standards and attitudes towards using CBAHI standards as a tool for quality improvement were 80.1%, 76.4%, and 72.0%, respectively. The highest item agreement percentage of the participating healthcare providers regarding the barriers that inhibit the hospital from obtaining the full benefit from the CBAHI accreditation was for the inexpedient IT tools (59.6%).

CONCLUSION

The current study's results demonstrated accepted perceptions and attitudes toward using CBAHI standards among Saudi healthcare providers. In addition, the identified barriers should be alleviated to improve the quality, effectiveness, and efficiency of the hospitals in Saudi Arabia. The findings also help clarify the accreditation operating process, which may be helpful to policymakers and stakeholders in making informed decisions on integrating accreditation standards.

Knowledge, attitudes, and practices toward blood donation in the Gaza Strip, Palestine

Aims

Both developing and developed countries are facing difficulties in finding regular donors. In areas that are exposed to frequent conflicts and wars, such as the Gaza Strip, there is a need for a continuous blood supply. This study aims to determine the level of knowledge, attitudes, and practices toward blood donation in the Gaza Strip, Palestine.

Methods

A cross-sectional study was conducted in 2022, in which 1506 participants were randomly selected from different governorates in the Gaza Strip. A structured and valid questionnaire was employed to assess the level of knowledge, attitudes, and practices toward blood donation. All statistical analyses were performed using SPSS version 28. The chi-square test was used to measure the significance of associations.

Results

A total of 1506 individuals living in the Gaza Strip participated. The total mean score of the overall knowledge and positive attitudes toward blood donation was 55.1% and 67.1%, respectively. Furthermore, 1236 (82.1%) of the study participants never donated blood. Of them, 260 (21.0%) demonstrated that they do not have information on when, where, and how to donate; 228 (18.4%) thought that they were not fit to donate; 187 (15.1%) demonstrated that they did not have time to donate; 143 (11.6%) feared health problems, and 132 (10.7%) feared anemia. On the contrary, 99 (36.7%) donated blood when a friend or relative needed blood, and 171 (63.3%) were voluntary donations. Statistically, a significant association was found between knowledge, attitudes, practices, and sociodemographic variables (p < 0.05 for all).

Discussion

The study findings indicated poor donation habits despite positive attitudes toward blood donation in the Gaza Strip, Palestine. This research emphasizes the need to recognize and correct the knowledge gap that results in unfavorable behaviors against blood donation.

Computer-aided diagnostic accuracy of pulmonary tuberculosis on chest radiography among lower respiratory tract symptoms patients

Even though the Gaza Strip is a low pulmonary tuberculosis (TB) burden region, it is well-known that TB is primarily a socioeconomic problem associated with overcrowding, poor hygiene, a lack of fresh water, and limited access to healthcare, which is the typical case in the Gaza Strip. Therefore, this study aimed at assessing the accuracy of the automatic software computer-aided detection for tuberculosis (CAD4TB) in diagnosing pulmonary TB on chest radiography and compare the CAD4TB software reading with the results of geneXpert. Using a census sampling method, the study was conducted in radiology departments in the Gaza Strip hospitals between 1 December 2022 and 31 March 2023. A digital X-ray, printer, and online X-ray system backed by CAD4TBv6 software were used to screen patients with lower respiratory tract symptoms. GeneXpert analysis was performed for all patients having a score > 40. A total of 1,237 patients presenting with lower respiratory tract symptoms participated in this current study. Chest X-ray readings showed that 7.8% (n = 96) were presumptive for TB. The CAD4TBv6 scores showed that 11.8% (n = 146) of recruited patients were presumptive for TB. GeneXpert testing on sputum samples showed that 6.2% (n = 77) of those with a score > 40 on CAD4TB were positive for pulmonary TB. Significant differences were found in chest X-ray readings, CAD4TBv6 scores, and GeneXpert results among sociodemographic and health status variables (P-value < 0.05). The study showed that the incidence rate of TB in the Gaza Strip is 3.5 per 100,000 population in the Gaza strip. The sensitivity of the CAD4TBv6 score and the symptomatic review for tuberculosis with a threshold score of >40 is 80.2%, and the specificity is 94.0%. The positive Likelihood Ratio is 13.3%, Negative Likelihood Ratio is 0.2 with 7.8% prevalence. Positive Predictive Value is 52.7%, Negative Predictive Value is 98.3%, and accuracy is 92.9%. In a resource-limited country with a high burden of neglected disease, combining chest X-ray readings by CAD4TB and symptomatology is extremely valuable for screening a population at risk. CAD4TB is noticeably more efficient than other methods for TB screening and early diagnosis in people who would otherwise go undetected.

The Quality of Blood Donation Services and Its Association with Blood Donors' Trust and Loyalty at Makkah Blood Donation Centers in Saudi Arabia: A Cross-Sectional Study

The current cross-sectional study was conducted to determine the quality of blood donation services and its association with blood donors' trust and loyalty at Makkah blood donation centers in Saudi Arabia. A total of 373 healthy blood donors aged ≥18 years who visited blood donation centers in Makkah, Saudi Arabia, between 1st and 28th February 2023 were recruited using a census sampling method. A pre-tested and validated Arabic language questionnaire was employed. The study survey included a checklist of sociodemographic variables (seven items), as well as seven-point Likert-scale questions on the quality of blood donation services (21 items), questions to assess the participant's level of trust in blood donation centers (4 items), and questions to evaluate the level of loyalty to blood donations (4 items). SPSS (version 24) was used for data analysis. A total of 373 blood donors were included in this study. Of them, 240 (64.3%) were males and 133 (35.7%) were females. The vast majority of the study participants, 330 (88.5%), had a high educational level. The overall average agreement score for the quality of blood donation services was 71.7%. Furthermore, the overall average item agreement score for trust in blood donation centers and places was 83.0%, while the overall average item agreement score for loyalty to blood donation was 72.1%. Moreover, after adjustment for potential confounding factors, high levels of quality in blood donation services were associated with high levels of trust and loyalty among the blood donors (OR: 1.518, CI 95%: 0.321-0.864 and OR: 2.466, CI 95%: 0.285-0.763, respectively) (p-value < 0.05 for all). The overall quality of, trust in, and loyalty to blood donation services were 71.7%, 83.0%, and 72.1%, respectively. In addition, high levels of quality in blood donation services could improve blood donors' trust and loyalty levels at Makkah blood donation centers in Saudi Arabia.

Association of Household Food Insecurity With Dietary Intakes and Nutrition-Related Knowledge, Attitudes, and Practices Among School-Aged Children in Gaza Strip, Palestine

Background

The present study aimed to determine the association of household food insecurity with dietary intakes and nutrition-related knowledge, attitudes, and practices (KAP) among school-aged children.

Methods

This cross-sectional study was conducted among a representative sample of school-aged children. A total of 380 children and their parents were selected from all Gaza strip governorates, using a random sampling method. The demographic and socioeconomic characteristics; the Radimer/Cornell food security scale; two non-consecutive days of 24-h dietary recall; anthropometric measurements; and the Food and Agriculture Organization KAP-questionnaire (Module 3) were employed. Statistical analysis was performed using SPSS version 25.

Results

About 71.6% of school-aged children were household food-insecure, while 28.4% were household food-secure. Significant associations were found between living area, educational level, household monthly income, weight for age and BMI for age z-scores, underweight, malnutrition status, intakes of protein, iron, vitamin D, and zinc among household food-secure, and household food-insecure. After adjustment for confounding variables, having nutrition-related adequate KAP were associated with lower odds of being food-insecure household [OR = 0.519, 95% (CI = 0.320–0.841)], [OR = 0.510, 95% CI = (0.315–0.827)], and [OR = 0.466, 95% CI = (0.285–0.763), P < 0.05 for all], respectively.

Conclusions

Low socioeconomic status, low anthropometric indices, poor dietary intakes may be associated with a high level of food-insecurity; while having nutrition-related adequate KAP may be protective against food-insecurity among school-aged children.

Association of household food insecurity with dietary intakes and nutrition-related knowledge, attitudes, and practices among parents, aged ≥ 18 years in Gaza Strip, Palestine: A descriptive study

The purpose of this study was to examine the association between household food insecurity and dietary intake and nutrition-related knowledge, attitudes, and practices (KAP) among parents aged ≥18 years in the Gaza Strip, Palestine. The current cross-sectional study was carried out in 2021 among adults (mothers and fathers) aged ≥18 years. A total of 614 participants were selected from all Gaza Strip governorates using a cluster random sampling method. To assess the nutrition-related KAP, we employed the Food and Agriculture Organization (FAO) of the United Nations questionnaire (Modules 5, 6, 7, and 9). Data regarding household food security status, demographic and socioeconomic characteristics of the study participants, anthropometric measurements, and dietary intakes were obtained using standard questionnaires and methods. Statistical analysis was performed using SPSS version 25. About 71.5% and 28.5% of the study participants were household food-insecured and household food-secured, respectively. Significant associations were found between participants from household food-secured and household food-insecured concerning several socio-demographic variables, anthropometric measures, intakes of energy, protein, carbohydrate, and calcium; nutrition-related knowledge and attitudes toward undernutrition and vitamin A deficiency; nutrition-related KAP of iron deficiency anemia; and nutrition-related attitudes and practices of food safety (P-values < 0.05 for all). In conclusion, the demographic and socioeconomic status, anthropometric measurements, and poor dietary intakes may be associated with high levels of household food insecurity, while having nutrition-related adequate KAP may be associated with low levels of household food insecurity among parents aged ≥18 years.

Households' Food Insecurity and Its Association with Demographic and Socioeconomic Factors in Gaza Strip, Palestine: A Cross-Sectional Study

Background

This sudy aimed to identify the prevalence of household's food insecurity and its association with demographic and socioeconomic factors.

Methods

A cross-sectional study was conducted in September 2021 among a representative sample of households in the Gaza strip governorates. A total of 1167 households randomly selected from all five governorates and were included in the study. The Radimer/Cornell food security scale was used to determine the prevalence and levels of household food insecurity. The household's demographic and socioeconomic characteristics were obtained using an interview-based questionnaire. Statistical analysis was performed using SPSS version 25.

Results

The overall prevalence of household's food insecurity was 71.5%. The prevalence by governorates was highest in Gaza (30.8%), followed by Khanyounis (23.0%), North-Gaza (18.6%), Middle-Area (15.2%) and Rafah (12.4%). Regarding the food insecurity levels, 333 (28.5%) of the households were food secure, 422 (36.2%) had mild food insecurity, 161 (13.8%) had moderate food insecurity, and 251 (21.5%) had severe food insecurity. Significant associations were found between governorates, monthly income, homeownership, work status with the household's food insecurity, (Crude OR [COR] = 2.02, 95% CI = [1.02–3.98], P value < 0.05), (COR = 2.00, 95% CI = [1.04–2.75], P value < 0.05), (COR = 2.36, 95% CI = [1.39–3.99], P value < 0.05), and (COR = 1.14, 95% CI = [0.66–1.97], P value < 0.05), respectively.

Conclusions

Our study demonstrates that food insecurity is highly prevalent in the Gaza strip and is associated with poor living conditions. Therefore, this high prevalence should be seriously discussed and urgently considered.

Households' Food Insecurity and Their Association With Dietary Intakes, Nutrition-Related Knowledge, Attitudes and Practices Among Under-five Children in Gaza Strip, Palestine

The present study aimed to determine the households' food insecurity and their association with dietary intakes, nutrition-related knowledge, attitudes and practices (KAP) among under-five children in the Gaza Strip, Palestine. This cross-sectional study was conducted in 2021 among a representative sample of under-five children. A total of 350 children and their proxy were selected from all Gaza strip governorates, using a cluster random sampling method. The Radimer/Cornell food-security scale was used. A 24-h dietary recall was employed for dietary intakes assessment. Nutrition-related KAP for feeding under-five children, anthropometric measurements, and demographic-socioeconomic characteristics were obtained with an interview-based questionnaire. Statistical analysis was performed using SPSS version 25. The children from food-insecure households had a high prevalence of moderate underweight (30.4%), stunting (32.8%), wasting (9.6%), and acute undernutrition (30.4%). Between food-insecure and food-secure groups there were significant differences in weight, height/length, mid-upper arm circumference, weight-for-age and mid-upper arm circumference z-scores, underweight, acute undernutrition, intakes of protein, fat, vitamin D, zinc, continued breastfeeding, having nutrition-related adequate knowledge, having nutrition-related positive attitudes, and achieved minimum dietary diversity score (P < 0.05 for all). Additionally, about (56.0%) food-insecure households have inadequate nutrition-related knowledge, (77.6%) have nutrition-related negative attitudes, and (95.2%) did not achieve a minimum dietary diversity score. In conclusion, the children from food-insecure households had a high prevalence of moderate underweight, stunting, wasting, and acute undernutrition. Moreover, low economic status, poor dietary intakes, low levels of nutrition-related KAP, and lack of dietary diversity could contribute to the high levels of food insecurity among under-five children.

Attitudes and Satisfaction toward the Taken Procedures to Tackle COVID-19 Pandemic in Palestine

Background

Since the beginning of the COVID-19 pandemic, there have been differences in the mitigation strategies implemented by governments worldwide. In addition, people's acceptance and adherence to these strategies, such as avoiding large gatherings and shelter in place, varied. The current study aims to assess the attitude and satisfaction with the procedures to tackle COVID-19 in Palestine.

Methods

This cross-sectional descriptive study was conducted in the Palestinian territories, including, Gaza Strip, West Bank, and East Jerusalem, between April 29, 2020, and June 5, 2020, using a validated online questionnaire. The questionnaire included three sections: socio-demographic characteristics, attitude towards the measures and behaviors to avoid COVID-19 infection and its consequences, and level of people satisfaction with the response of the community and local authorities to combat the COVID-19 pandemic. A convenience sampling method was used to select participants. Statistical analysis was performed using SPSS version 26.

Results

A total of 570 adults aged ≥18 years (56.3% males and 43.7% females) were included in the study. The mean positive attitude score (average % agree or strongly agree) was 94.22%; 95.24%, 95.18%, and 92.18% in the Gaza Strip, West Bank, and East Jerusalem, respectively. While, the mean satisfaction score was 44.26%, distributed as 47.16%, 46.1%, and 39.22% in the Gaza Strip, West Bank, and East Jerusalem, respectively. Additionally, there were statistically significant variations by most attitude and satisfaction variables across the governorates included in the study (p < 0.05). The current study demonstrated high levels of positive attitude but suboptimal level of satisfaction toward the taken procedures to tackle COVID-19 in Palestine.

Conclusions

Varied implementation strategies to improve the levels of satisfaction toward the approaches to combat the COVID-19 pandemic are recommended.

Preparedness and Readiness Strategies for Addressing the COVID-19 Pandemic in Fragile and Conflict Settings: Experiences of the Gaza Strip

The COVID-19 pandemic is a global public health threat of serious concern, especially in conflict settings that face fragility and lack adequate resources and capacities. Gaza suffers from a blockade imposed by the Israeli occupation, environmental deterioration, confiscation of lands, demolition of houses and hospitals, restrictions on movement, lack of control over natural resources, and financial constraints. Gaza's population is consequently living in a poor humanitarian situation with high unemployment rates, poverty, over-crowdedness, and a weak health system. This makes Gaza incredibly fragile and affects its ability to respond to the COVID-19 pandemic effectively. The pandemic is expected to deepen Gaza's systems' fragility, which is already overstretched beyond their limits. This will hinder its capacity to deal with the pandemic, and other pre-existing pressing humanitarian needs. Therefore, in this review, we comprehensively explored Gaza's policy failures and successes related to the COVID-19 preparedness and response by state and non-state actors and recommend potential solutions and alternatives. We have addressed critical issues including the health system, water, sanitation, hygiene, socio-economic, education, food security, and others. In Gaza, effectiveness in combating the COVID-19 pandemic can only come from committed political will, transparency from all regulators, strategic dialogue, comprehensive planning, and active international support.

Implementation challenges of an integrated One Health surveillance system in humanitarian settings: A qualitative study in Palestine

Objectives

Several factors have changed interactions between people, animals, plants, and the environment - renewing the relevance of the One Health surveillance system in the fight against zoonotic diseases such as COVID-19. Therefore, this study aimed to explore barriers to implementing an integrated One Health surveillance system in Palestine.

Methods

This qualitative study was conducted from April 2020 until August 2020. Data were collected using semi-structured interview guides. Seven key stakeholders were interviewed during data collection. A thematic analysis was performed.

Results

Four overarching themes emerged explaining barriers to integrated implementation of the One Health surveillance system. They are lack of policy coherence, limited financial resources, poor governance and leadership, and lack of One Health training programmes.

Conclusion

Improved understanding of the transmission and effective control (including One Health approach) of zoonotic disease and better governance and leadership are critical in the diseases that threaten public health, such as the COVID-19.

The Association between Changes in Coronary Artery Calcium Scores, Dietary Intake, Physical Activity, and Depression Symptoms among the Population of Gaza Strip, Palestine

Background

This study aimed to identify the association between macronutrient intake, physical activity, and depressive symptoms and changes in coronary artery calcium score among the population of Gaza Strip.

Method

The study sample consisted of 269 individuals who underwent non-enhanced coronary computed tomography using 64-slice MDCT (Siemens, Germany) at Al-Shifa medical complex between September 2017 and January 2018. The study participants were divided into two groups; group one, consisting of coronary calcium calcification scoring (CAC) of greater than zero (CAC score > 0), and group two, CAC less than or equal to zero (CAC score ≤ 0). Data about macronutrient intake, physical activity, and depressive symptoms were collected using a validated self-administered questionnaire. Additionally, the participants' anthropometric characteristics and blood biochemical markers were measured.

Results

Out of 269 participants, 45-recorded CAC score > 0; 72% of them were males with a mean age of 52.6 ± 5.4 years. Significant differences between the two groups in terms of total energy, lipid intake, and carbohydrate were found (P-value of 0.020, 0.012, and 0.034, respectively). No significant differences were recorded in protein intake, physical activity, and depression. Multivariate logistic regression analysis under adjustment for possible confounding factors revealed that macronutrient intake, physical activity, and depressive symptoms were not associated with the development of CAC in two models.

Conclusion

Based on our findings, macronutrient intake, physical activity, and depressive symptoms are not associated with the development of CAC among the population of Gaza.

Systematic review and meta-analysis of the susceptibility of ABO blood group to COVID-19 infection

Background

Numerous studies investigate the association between the ABO blood groups and the occurrence of COVID-19 infection; discordant findings were reported. Therefore, the purpose of this meta-analysis was to evaluate the existing evidence on the susceptibility of the ABO blood group to COVID-19 infection.

Methods

Systematically searched published articles in PubMed, Google Scholar, Scopus, and EMBASE between 1 st January 2020 and 21 st March 2021. After quality control and the exclusion of irrelevant studies, 16 studies were included in the final analysis.

Results

Although the random-effect meta-analysis revealed a large heterogeneity among studies, I 2 = 99.197 %. The pooled event rates and (95 % CIs) for A, O, B, and AB blood group were 0.459 (95 %CI: 0.358–0.441), 0.342 (95 %CI: 0.298–0.374), 0.180 (95 %CI: 0.150–0.214), and 0.076 (95 %CI: 0.055–0.127), respectively. These results indicated that the COVID-19 infection rate was higher in persons with blood group A > O > B > AB. Overall, the ABO blood group's vulnerability to COVID-19 infection was statistically significant (pooled p -value<0.001).

Conclusion

This meta-analysis offers a further indication of blood group A individuals' vulnerability to COVID-19 infection, and blood type AB are linked to a lower risk of COVID-19 infection.

Impact of the coronavirus disease 2019 pandemic on the Palestinian family: A cross-sectional study

INTRODUCTION

The current study aims to understand and assess the consequences of the coronavirus disease 2019 pandemic on Palestinian families.

METHODS

This online community-based cross-sectional descriptive study was conducted between 19 April 2020 and 5 June 2020, using a validated questionnaire. The questionnaire comprised of three sections: sociodemographic characteristics, living conditions, and impact of the coronavirus disease 2019 pandemic. A convenience sampling method was used to select participants.

RESULTS

A total of 570 adults aged ⩾18 years participated in the study. Of them, 258 (45.3%), 120 (21%), and 192 (33.7%) were residing in the Gaza Strip, West Bank, and East Jerusalem, respectively. A large portion of participants (73.2%) reported that the containment measures of the coronavirus disease 2019 pandemic had caused an excessive burden on their families; 549 (96.3%) revealed that water supplies were not always available at home. However, paying attention to personal hygiene and home cleaning was more than usual before the announcement of the coronavirus disease 2019 pandemic. The mean times of going out of their homes have dropped significantly following the onset of the pandemic, p value = 0.001 (95% confidence interval). In addition, 192 (33.7%) participants reported that they changed to working remotely from home with 66 (11.6%) having lost their employment.

CONCLUSION

The coronavirus disease 2019 pandemic was associated with an additional burden on the Palestinian families. Moreover, we suggest discussing the obtained results with local and national stakeholders to ensure that they know to improve their actions.

Water, sanitation, and hygiene risk factors of acute diarrhea among children under five years in the Gaza Strip

This cross-sectional community household-based study aims to evaluate the water, sanitation, and hygiene facilities in the Gaza Strip and to investigate their associations with the occurrence of acute diarrhea among children under five years. A survey using a structured questionnaire was conducted on 1,857 households with an child under five years from August 2017 to June 2018. About 69.7% of heads of households reported a diarrheal episode among their children during the two months preceding the survey. Multivariable logistic regression showed that sewage water observed around the households was associated with an increased risk of acute diarrhea (AOR = 2.45; P &lt; 0.001; 95% CI: 1.83–3.27). Nevertheless, the allocation of a special water tank for desalinated drinking water at home (AOR = 0.3; P = 0.02; 95% CI: 0.1–0.8), the connection of households to a closed sewerage system (AOR = 0.56; P &lt; 0.001; 95% CI: 0.43–0.73), and handwashing practices before and after eating (AOR = 0.42; P = 0.003; 95% CI: 0.24–0.74 and AOR = 0.50; P = 0.03; 95% CI: 0.26–0.94, respectively), as well as using desalinated water sources for drinking purposes, were inversely associated with the incidence of acute diarrhea among children under five. Further improvements in the existing sewerage system and the intensification of sanitation and hygiene promotion programs at the household levels may reduce the risk of acute diarrhea among children under five years in the Gaza Strip.

Neighbourhood socioeconomic status and overweight/obesity: a systematic review and meta-analysis of epidemiological studies

OBJECTIVE

Low neighbourhood socioeconomic status (NSES) has been linked to a higher risk of overweight/obesity, irrespective of the individual's own socioeconomic status. No meta-analysis study has been done on the association. Thus, this study was done to synthesise the existing evidence on the association of NSES with overweight, obesity and body mass index (BMI).

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

PubMed, Embase, Scopus, Cochrane Library, Web of Sciences and Google Scholar databases were searched for articles published until 25 September 2019.

ELIGIBILITY CRITERIA

Epidemiological studies, both longitudinal and cross-sectional ones, which examined the link of NSES to overweight, obesity or BMI, were included.

DATA EXTRACTION AND SYNTHESIS

Data extraction was done by two reviewers, working independently. The methodological quality of included studies was assessed using the Newcastle-Ottawa Scale for the observational studies. The summary estimates of the relationships of NSES with overweight, obesity and BMI statuses were calculated with random-effects meta-analysis models. Heterogeneity was assessed by Cochran's Q and I² statistics. Subgroup analyses were done by age categories, continents, study designs and NSES measures. Publication bias was assessed by visual inspection of funnel plots and Egger's regression test.

RESULT

A total of 21 observational studies, covering 1 244 438 individuals, were included in this meta-analysis. Low NSES, compared with high NSES, was found to be associated with a 31% higher odds of overweight (pooled OR 1.31, 95% CI 1.16 to 1.47, p<0.001), a 45% higher odds of obesity (pooled OR 1.45, 95% CI 1.21 to 1.74, p<0.001) and a 1.09 kg/m² increase in mean BMI (pooled beta=1.09, 95% CI 0.67 to 1.50, p<0.001).

CONCLUSION

NSES disparity might be contributing to the burden of overweight/obesity. Further studies are warranted, including whether addressing NSES disparity could reduce the risk of overweight/obesity.

Prevalence of diarrheal illness and healthcare-seeking behavior by age-group and sex among the population of Gaza strip: a community-based cross-sectional study

BACKGROUND

In the Gaza strip, diarrhea is one of main reasons for children visiting primary healthcare centers. Hence, we investigate predictors of the diarrheal illness and health care-seeking behavior among different age groups.

METHODS

This community-based cross-sectional survey was conducted from August 2017 to June 2018 among 1857 households. A pretested structured questionnaire included information about socio-demographic, sanitation, hygiene, source of water, diarrheal illness, and seeking healthcare in households was administered to head of household. To achieve representativeness for the five Gaza's governorates, a cluster random sampling was applied.

RESULTS

Of the 1857 household's heads, 421 (22.7%) reported an episode of diarrhea during the 48 h preceding the interview resulting an overall prevalence rate of 3.8 per 100 individuals. The prevalence of diarrhea was statistical significant greater in males (5.4/100) compared to females (1.3/100) in all age groups (p <  0.05). Socio-demographic, economic, water, sanitation, and hygiene factors were predictors of the diarrheal illness and seeking of non-professional healthcare for diarrhea illness treatment among. A transition behavior from professional to non-professional and vice versa in seeking healthcare in each diarrheal episode was found.

CONCLUSIONS

We recommend improving the status of water, sanitation, and hygiene in the Gaza strip's households to reduce diarrhea among the population of Gaza strip. Community sensitization about the importance of seeking care at primary health centers because treatment of children is available for free or in low costs.

Household drinking water safety among the population of Gaza Strip, Palestine: knowledge, attitudes, practices, and satisfaction

A descriptive cross-sectional study employing a structured questionnaire was employed to assess knowledge, attitude, practice, and satisfaction (KAPS) of Gaza's community on issues related to household drinking water safety. The results showed that of 1,857 household heads, 1,621 (87.3%) were males, with the majority (967, 52.1%) having a university educational level. Of surveyed households, 744 (40.1%) consisted of 5–7 persons and 885 (47.7%) of the households resided in refugee camps. Mean percentages for KAPS were 82 ± 15.5%, 64.9 ± 39.7%, 53.2 ± 14.1%, and 37.3 ± 26.56%, respectively. There were statistically significant associations between some sociodemographic variables and mean percentage of KAPS scores. Educational level was the only variable significantly associated (p &lt; 0.05) with all mean KAPS scores. There was a significant positive linear correlation between knowledge-attitude (r = 0.362, p &lt; 0.05), but a significant negative linear correlation between knowledge-practice (r = −0.070, p &lt; 0.05) was also observed. Therefore, the Local Government Authority (LGA) should arrange community awareness campaigns on the importance of safety and hygiene measures of drinking water storage. Furthermore, and due to the poor financial capabilities of the LGA in Gaza, it is highly recommended that LGA contact relevant international donors in order to support programs aiming at improving household water supply.

Simultaneous removal of cationic methylene blue and anionic reactive red 198 dyes using magnetic activated carbon nanoparticles: equilibrium, and kinetics analysis

For the simultaneous adsorption of cationic dye (methylene blue, MB) and anionic dye (reactive red 198, RR198) from aqueous solution, magnetic activated carbon (MAC) nanocomposite as a promising adsorbent was prepared and used. The concentration of MB at different time intervals was determined using a UV-Vis spectrophotometer while the concentration of RR198 was determined using a high performance liquid chromatography (HPLC) system. The effect of solution pH, contact time, adsorbent amount, and dye concentration were investigated. Also, both kinetic and isotherm experiments were studied. The optimum pH was 10 and 5.5 for adsorption of MB and RR198, respectively, and the equilibrium status was achieved after 120 min. The adsorption kinetics was controlled by the pseudo-second order kinetic model more than pseudo-first order. The best-fitted isotherms were Freundlich and Langmuir models for MB and RR198, respectively. The higher values of Freundlich adsorption capacity (K_f) for MB in comparison with RR198 refer to MAC affinity to remove cationic dyes more than anionic dyes. Apparently, there was no substantial change in the adsorption efficiency among the 10 adsorption-desorption cycles. Overall, MAC can be considered as an effective and efficient viable adsorbent for cationic and anionic dyes removal from industrial wastewaters.
