RESUMO

BACKGROUND: The Gulf Cooperation Council (GCC) countries relied, until recently, solely on import duties for tobacco products. The agreement for the introduction of an excise and value added tax (VAT) in 2016 and 2017, respectively, in most GCC countries, was a major breakthrough for public health. There is, however, ample room for improvement. METHODS: The study examines the outcomes of tax reforms, for both public health and public finances, based on the World Health Organization (WHO) recommendations and best practices worldwide. Tax simulations were performed using the WHO TaXSiM model. The study is based on data from Saudi Arabia, the only GCC country for which sufficient data existed. RESULTS: We recommend a stepwise tax reform, which involves increasing the current ad valorem excise tax rate, phasing out import duties keeping total tax share constant and introducing a minimum excise, and finally switching to a revenue-neutral specific excise. Specific excises must be adjusted for inflation and income increases. If implemented, cigarette tax reform simulations show that the recommended reforms would lead to a higher than 50% increase in cigarette prices, 16% reduction in cigarette sales and almost 50% increase in total cigarette tax revenue. A significant number of cigarette-related deaths would be averted. CONCLUSIONS: The recommended tax reforms are expected to lead to significant improvements in both public health and tobacco tax revenues. Our results provide useful insights that are of relevance to the whole GGC region. The effectiveness of the reforms, however, requires a strong tax and customs administration, including the establishment of a good database to monitor and advance public health.

RESUMO

BACKGROUND: The economic cost of smoking has been determined in many high-income countries as well as at a global level. This paper estimates the economic cost of smoking and secondhand smoke (SHS) exposure in the six Gulf Cooperation Council (GCC) countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates), for which no detailed study exists. METHODS: We used data from the Global Burden of Diseases Study 2016 and the cost-of-illness approach to estimate direct costs (healthcare expenditures) and indirect costs (productivity losses due to morbidity and mortality). Indirect cost was estimated with and without the inclusion of musculoskeletal disorders, using the human capital approach. RESULTS: Total cost of smoking and SHS was estimated to be purchasing power parity (PPP)$ 34.5 billion in 2016, equivalent to 1.04% of the combined gross domestic product (GDP). SHS accounted for 20.4% of total cost. The highest proportion of indirect cost resulted from smoking in men and middle-aged people. The main causes of morbidity cost from smoking and SHS were chronic respiratory diseases and type 2 diabetes mellitus, respectively. Cardiovascular diseases were the main contributor to mortality cost for both smoking and exposure to SHS. Including musculoskeletal disorders increased total cost to PPP$ 41.3 billion (1.25% of the combined GDP). CONCLUSION: The economic cost of smoking and SHS in the GCC states is relatively low compared with other high-income countries. Scaling-up implementation of evidence-based policies will prevent the evolution of a tobacco epidemic with its negative consequences for health and public finances.

RESUMO

BACKGROUND: A different ethos with respect to the perception of medical ethics prevails in societies in transition such as those in the Arabian Peninsula, which makes it difficult to apply international principles of bioethics in medical practice. This study aimed to develop and psychometrically test an instrument that measures physicians' awareness of bioethics and medical law and their attitudes towards the practice of medical ethics. Additionally, it examined physician correlates influencing the awareness of bioethics. METHODS: Following a rigorous review of relevant literature by a panel of experts, a 13-item instrument, the Omani physicians' bioethics and medical law awareness (OBMLA) questionnaire was developed with the aim of assessing physicians' awareness of bioethics and medical law. The study tool's construct validity and internal consistency reliability were examined by exploratory factor analysis (EFA) and Cronbach's alpha. In a cross-sectional study, the questionnaire was distributed among a random sample of 200 physicians at a tertiary hospital in Muscat, Oman. Participant characteristics that may influence awareness of bioethics and medical law were explored. RESULTS: The EFA of the OBMLA questionnaire resulted in three well-loading factors: (1) Physicians' bioethics practice subscale (2) incentive related bioethics subscale and (3) medical law awareness subscale. Internal consistency reliability ranged between Cronbach's α: 0.73-0.8. Of the total 200 participants, 52% reported that teaching medical ethics during medical school was inadequate. The overall mean (standard deviation, SD) of the bioethics awareness score and Omani medical law awareness were 27.6 (3.5) and 10.1 (2.1) respectively. The majority of physicians (73%) reported that they frequently encountered ethical dilemmas in their practice and 24.5% endorsed the view that unethical decisions tended to occur in their practice. CONCLUSION: The study provides an insight into the practice of bioethics, and the awareness of bioethics and medical law among physicians in a teaching hospital in Oman. The OBMLA questionnaire appears to be a valid and reliable tool to assess a physician's awareness of bioethics and medical law. In this preliminary study, it appears that participants have suboptimal scores on the indices which measure practice and awareness of bioethics and medical law.

RESUMO

BACKGROUND: Road traffic accidents are known to be the main cause of traumatic brain injury (TBI). TBI is also a leading cause of death and disability. This study, by means of the idiographic approach (single-case experimental designs using multiple-baseline designs), has examined whether methylphenidate (MPH - trade name Ritalin) had a differential effect on cognitive measures among patients with TBI with the sequel of acute and chronic post-concussion syndromes. The effect on gender was also explored. METHODS: In comparison with healthy controls, patients with TBI (acute and chronic) and accompanying mild cognitive impairment (MCI) were screened for their integrity of executive functioning. Twenty-four patients exhibiting executive dysfunction (ED) were then instituted with the pharmacological intervention methylphenidate (MPH). The methylphenidate was administered using an uncontrolled, open label design. RESULTS: The administration of methylphenidate impacted ED in the TBI group but had no effect on mood. Attenuation of ED was more apparent in the chronic phases of TBI. The effect on gender was not statistically significant with regard to the observed changes. CONCLUSIONS: To our knowledge, this is the first feasibility trial from the Arabian Gulf to report the performance of a TBI population with mild cognitive impairment according to the IQCODE Arabic version. This investigation confirms anecdotal observations of methylphenidate having the potential to attenuate cognitive impairment; particularly those functions that are critically involved in the integrity of executive functioning. The present feasibility trial should be followed by nomothetic studies such as those that adhere to the protocol of the randomized controlled trial. This evidence-based research is the foundation for intervention and future resource allocation by policy- or public health decision-makers.

RESUMO

PURPOSE: Evidence from industrialized/developed countries showed that colorectal cancer (CRC) incidence rates have significantly dropped due to the widespread use of colonoscopy. In Arab countries, however, the CRC had been reported to have increased. Despite the concerted effort in the primary prevention and widespread use of colonoscopy, to our knowledge, there have been no reports of the prevalence rate of CRC among colonoscopy recipients from Oman. This study aims to explore the CRC prevalence estimates over selected sociodemographic characteristics among colonoscopy-recipients at a tertiary hospital in Oman over five years of follow-up. The regional variations in Oman were also examined in this study. METHODS: This hospital-based cross-sectional study reviewed reports of colonoscopies performed over 5-years of retrospective follow-up at a tertiary hospital in Oman. CRC prevalence estimates were calculated over age, gender, governorate, and time of follow-up. RESULTS: A total of 442 CRC cases were enumerated among 3701 colonoscopies, with an overall CRC prevalence estimate of 11.9 per 100 colonoscopies (95% CI: 10.9, 13.0). Gender-specific CRC prevalence was higher among males compared with females (13.3 vs. 10.5). Age-specific CRC prevalence increased with advancing age, from 2.8 among those less than 40 years of age to 26.5 among aged 70 years or more. Regional CRC prevalence was highest among residents in Batinah Governorate. Over the 5-years of follow-up, there was a slow rise in CRC prevalence with an annual increment of 0.59%. CONCLUSION: The study provides supportive evidence for a steady increase in CRC prevalence over age categories and years of follow-up and depicted the variations of gender-specific CRC prevalence estimates over increasing age categories. The study calls for timely formulation and adoption of national CRC screening programs centered on the colonoscopy use as primary prevention and maximizing its utilization and efficiency.

RESUMO

BACKGROUND: Benefits of physical activity in the management of diabetes are well documented. However, evidence on the effectiveness of interventions integrating physical activity in diabetes care is sparse especially in the countries of the Gulf Cooperation Council. The results from this study will increase our understanding of the use of multi-component interventions aimed at increasing physical activity levels in inactive adults with type 2 diabetes in primary health care in Oman. METHODS/DESIGN: The study is a one year 1:1 cluster randomized controlled trial of the MOVEdiabetes programme (intervention) versus usual care in eight primary health care centres in Oman. The MOVEdiabetes programme utilizes face to face physical activity consultations promoting 150 min of moderate to vigorous physical activity per week (≥600MET-mins/week), pedometers to self-monitor step counts and monthly telephone WhatsApp messages for follow up support. Inactive adults with type 2 diabetes and no contraindication to physical activity will be recruited over a two months period, and followed up for 12 months. To demonstrate a 50% between group difference in physical activity levels (MET-mins/week) over 12 months, (at a power of 80%, and significance level of 5%), 128 participants would be required to complete the study (64 in each arm). Based on a drop-out rate of 20%, 154 participants would require to be recruited (77 in each arm). Assuming a recruitment rate of 70%, 220 potential eligible participants would need to be approached. The primary outcome is change in levels of physical activity measured by the Global Physical Activity Questionnaire. In addition, accelerometers will be used in a sub group to objectively assess physical activity. Secondary outcomes include changes in metabolic and cardiovascular biomarkers, change in self-reported health, social support, self-efficacy for physical activity, and perceived acceptability of the program. All intervention delivery and support costs will be monitored. DISCUSSION: This study will contribute to the evidence on the feasibility, cultural acceptability and efficacy of interventional approaches for increasing physical activity in primary care for persons with type 2 diabetes in Oman. TRIAL REGISTRATION: International Standard Randomised Controlled Trials No: ISRCTN14425284 . Registered 12 April 2016.

RESUMO

Spirulina (SP) (Arthrospira platensis; previously Spirulina platensis) is a filamentous blue-green microalga (cyanobacterium) with potent dietary phytoantioxidant and anticancerous properties. We investigated the chemopreventive effect of SP against 7,12-dimethylbenz[a]anthracene (DMBA)-induced rat breast carcinogenesis, and further studied its underlying mechanisms of action in vitro. Remarkably, SP cleared DMBA-induced rat mammary tumors, which was clearly confirmed by morphological and histological methods. SP supplementation reduced the incidence of breast tumors from 87% to 13%. At the molecular level, immunohistochemical analysis revealed that SP supplementation reduced expression of both Ki-67 and estrogen α. More interestingly, molecular analysis in the in vitro experiments indicated that SP treatment inhibited cell proliferation by 24 hours, which was accompanied by increased p53 expression, followed by increased expression of its downstream target gene, Cdkn1a (alias p21 or p21(Waf1/Cip1)). In addition, SP increased Bax and decreased Bcl-2 expression, indicating induction of apoptosis by 48 hours after SP treatment. To our knowledge, this is the first report of in vivo chemopreventive effect of SP against DMBA-induced breast carcinogenesis in rat, supporting its potential use in chemoprevention of cancer.

RESUMO

BACKGROUND: Despite that hereditary diseases are widespread among the Arab population due to high rates of consanguineous marriages, research regarding community awareness towards premarital carrier screening in some countries such as Oman, is extremely scarce. This study aimed to investigate knowledge and attitude towards premarital carrier screening (PMCS) in Oman. METHODS: A cross-sectional study was conducted using a self-administered questionnaire which was distributed to 400 Omani adults aged 20-35 who attended primary healthcare institutions at the South Batinah Governorate in Oman. RESULTS: The majority of the participants (84.5%) believed that PMCS was necessary, and about half of them (49.5%) supported the view of making PMCS compulsory. On the contrary, approximately one third (30.5%) of the participants reported that they were not in favor of taking the blood screening test. Overall, unwillingness to perform pre-marital testing was associated with female gender, younger age, being single, less education, and increased income. CONCLUSION: Despite the relatively high level of knowledge, about one third of the participants were still reluctant to carry out premarital testing. Such attitude calls for immediate need for community-based campaigns to encourage the public to do premarital testing.

RESUMO

Research about bullying among school pupils in the Arab/Muslim population is scarce. This study evaluates the characteristics of bullying and its impact among school pupils in Oman via cross-sectional survey among eighth grade school pupils (n = 1,229) during the academic year 2006-2007. The participants were selected using stratified random selection among 6 administrative divisions of one the governorates in the country. Data were collected using self-completed structured questionnaires. This study found similar percentages of males and females (76%) have experienced one form of bullying, and the majority of the incidents (80%) occurred in the vicinity of the school. In almost half of the cases, the bullying was initiated by a student of the same age or older than the victim. The most common type of bullying encountered in this study was verbal (47.7%), followed by misuse (45.9%), physical (43.9%), and, finally, social isolation/exclusion (22.5%). Although the failure of an academic year was uncommon among victims of bullying, the number of pupils who missed 4-6 and ≥ 7 school days was higher among bullied pupils. If this study will withstand further research, educational initiatives are needed to mitigate the rate of bullying in Oman.

RESUMO

BACKGROUND: Antimicrobial resistance is increasingly recognized as a global challenge. A few studies have emerged on epidemiology of multidrug resistant organisms in tertiary care settings in the Arabian Gulf. AIM: To describe the epidemiology of multi-drug resistant organisms (MDRO) at Sultan Qaboos University Hospital, a tertiary hospital in Oman. METHODS: A retrospective review of MDRO records has been conducted throughout the period from January 2012 till December 2012. Organisms were identified and tested by an automated identification and susceptibility system, and the antibiotic susceptibility testing was confirmed by the disk diffusion method. RESULTS: Out of the total of 29,245 admissions, there have been 315 patients registered as MDRO patients giving an overall prevalence rate of 10.8 (95% CI 9.3, 12.4) MDRO cases per 1000 admissions. In addition, the prevalence rate of MDRO isolates was 11.2 (95% CI 9.7, 12.9) per 1000 admissions. Overall, increasing trends in prevalence rates of MDRO patients and MDRO isolates were observed throughout the study period. CONCLUSION: Antimicrobial resistance is an emerging challenge in Oman. Continuous monitoring of antimicrobial susceptibility and strict adherence to infection prevention guidelines are essential to prevent proliferation of MDRO. Along such quest, stringent antibiotic prescription guidelines are needed in the country.

RESUMO

The COVID-19 pandemic has dramatically threatened the Gulf Cooperation Council (GCC) countries which have a large proportion of foreign workers. The governments of GCC countries have proactively implemented a comprehensive set of policy measures, and up to our knowledge, a systematic analysis of qualitative and quantitative evidence on the government response is still lacking. We summarized the GCC countries' government response and quantitatively measured that response using four indexes-the Government Response Index, the Stringency Index, the Vaccine Index, and the Initial Response Index, to analyse their response for future pandemic preparedness. Overall, the government response of all the GCC countries to the COVID-19 pandemic has been comprehensive, stringent, and timely. Notably, the GCC countries have implemented comprehensive vaccine policies. In addition, they have worked actively to protect foreign workers to improve their access to health services and secure their essential living conditions, regardless of their immigrant status. All the GCC countries dynamically adjusted their response to the evolving COVID-19 epidemiological burden and started to relax the stringency of the control policies after the Omicron wave, though the governments had different response magnitudes as measured by the four indexes. These findings have provided several important lessons for future pandemic response and preparedness for countries with similar economic, demographic, and health contexts in (1) prompt actions of containment and closure policies with dynamic adjusting, (2) strengthening health system policies, (3) comprehensive vaccination policies with universal access, (4) equitable and free access to testing, diagnosis, and treatment for all, and (5) strengthening the resilience of health systems.

RESUMO

OBJECTIVE: While the Gulf Cooperation Council (GCC) countries have demonstrated a strong commitment to strengthening primary healthcare (PHC), the costs of delivering these services in this region remain relatively unexplored. Understanding the costs of PHC delivery is essential for effective resource allocation and health system efficiency. DESIGN: We used an ingredient-based method to estimate the cost of delivering a selection of services at PHC facilities in the six GCC countries in 2019. Services were categorised into eight programmes: immunisation; non-communicable diseases (NCDs); oral and dental care; child health; nutrition; mental health; reproductive, maternal, neonatal and child health and general practice. The cost estimation focused on two key ingredients: the costs of drugs and supplies and the healthcare workforce cost. The coverage rates of specific types of health services, including screening and mental health services, were also estimated. Data for the analysis were obtained from ministries of health, health statistics reports, online databases, national surveys and scientific literature. RESULTS: The estimated costs of delivering the selected services at public PHC facilities in the six GCC countries totalled US$5.7 billion in 2019, representing 0.34% of the combined 2019 GDP. The per capita costs varied from US$69 to US$272. General practice and NCD programmes constituted 79% of the total costs modelled while mental health ranged between 0.0% and 0.3%. Over 8 million individuals did not receive NCD screening services, and over 30 million did not receive needed mental health services in public PHC facilities across the region. CONCLUSIONS: To our knowledge, this is the first study to estimate the costs of services delivered at PHC facilities in the GCC countries. Identifying the main cost drivers and the services which individuals did not receive can be used to help strengthen PHC to improve efficiency and scale up needed services for better health outcomes.

RESUMO

Nonpharmacological treatment strategies that originate from sociocultural teachings and are beyond the scope of allopathic medicine are commonly used among people with epilepsy (PWE) in many parts of the world. The present study explored the types and sociodemographic correlates of complementary and alternative medicine (CAM) use among PWE in Oman among attendees of a neurological unit at a tertiary care center. Data on the types of CAM were gathered from telephone interviews. The relevant demographic and clinical characteristics of the participants were obtained from electronic medical records. Of the total of 101 participants, 73.3% were CAM users. The majority of these participants have not disclosed their CAM use to their allopathic health-care providers. The most common types of CAM reported were those falling under the 'mind-body' type (incantations and fumigation) and biologically based (herbal concoctions) or a combination of them. Compared to non-CAM users, a significant and greater proportion of CAM users attributed the etiology of their illness to nonbiomedical factors such as 'evil eyes' (P=0.04). The multivariate logistic regression model indicated that the use of CAM was highly associated with age of <30years (OR=3.09; 95% CI: 1.10, 5.46), unemployment (OR=2.04; 95% CI: 1.15, 6.39), having basic school education (OR=2.21; 95% CI: 0.83, 5.18), low family income (OR=1.52; 95% CI: 0.91, 2.11), and the presence of hypersalivation (OR=2.20; 95% CI: 1.01, 4.39). Further studies are needed to harmonize these two healing practices. On the whole, this study indicates that among attendees of tertiary care utilization, CAM is common among PWE in Oman. The most utilized type of CAM falls under the umbrella of mind-body practice.

RESUMO

BACKGROUND: Studies that explore the controversial association between parity and anaemia-in-pregnancy (AIP) were often hampered by not distinguishing incident cases caused by pregnancy from prevalent cases complicated by pregnancy. The authors' aim in conducting this study was to overcome this methodological concern. METHODS: A retrospective cohort study was conducted in Oman on 1939 pregnancies among 479 parous female participants with available pregnancy records in a community trial. We collected information from participants, the community trial, and health records of each pregnancy. Throughout the follow-up period, we enumerated 684 AIP cases of which 289 (42.2%) were incident cases. High parity (HP, ≥ 5 pregnancies) accounted for 48.7% of total pregnancies. Two sets of regression analyses were conducted: the first restricted to incident cases only, and the second inclusive of all cases. The relation with parity as a dichotomy and as multiple categories was examined for each set; multi-level logistic regression (MLLR) was employed to produce adjusted models. RESULTS: In the fully adjusted MLLR models that were restricted to incident cases, women with HP pregnancies had a higher risk of AIP compared to those who had had fewer pregnancies (Risk Ratio, RR = 2.92; 95% CI 2.02, 4.59); the AIP risk increased in a dose-response fashion over multiple categories of parity. In the fully adjusted MLLR models that included all cases, the association disappeared (RR = 1.11; 95% CI 0.91, 1.18) and the dose-response pattern flattened. CONCLUSIONS: This study shows the importance of specifying which cases of AIP are incident and provides supportive evidence for a causal relation between parity and occurrence of incidental AIP.

RESUMO

OBJECTIVES: Despite the worldwide increase in health research, few studies have evaluated the health research productivity in member states of the Gulf Health Council (GHC). This study solicited the period-prevalence and publication rates of health research productivity in the seven GHC countries. METHODS: We searched the Scopus database for publications between 1996 and 2018 and used the SCImago Journal and Country Rank portal to obtain the relevant information. We also recorded qualitative (citation-based) and quantitative (document recount) indicators. Overall and country-specific period-prevalence and publication rates were estimated and standardized to the corresponding overall Gulf Cooperation Council (GCC) population and country-specific population size. RESULTS: Overall, 112 409 articles were enumerated during the study period. The majority (59.8%) were from Saudi Arabia, followed by UAE (11.9%). The GCC publications were associated with 1 315 778 citations, which revealed a 46.0 Hirsch-index. The period-prevalence of health publications for the overall GCC region was 1320 publications per million population over 22 years, and the publication rate estimate was 13.2 (95% confidence interval (CI): 13.1-13.3) publication per 10 000 population. The highest publication rate estimate was noted in Qatar (36.5; 95% CI: 35.8-37.3), followed by Kuwait, Bahrain, Saudi Arabia, UAE, Oman, and Yemen. CONCLUSIONS: This study is the first study in the context of GCC to utilize period-prevalence and publication rates to chart health research productivity in the GCC region. Concerted efforts are required to improve the quality and quantity of the health research output in the GCC region.

RESUMO

OBJECTIVE: To assess the effect of parity on the occurrence of prediabetes defined as an abnormal fasting plasma glucose (5.6-6.9 mmol/l), an abnormal 2-hour oral glucose tolerance test (7.7-11.1 mmol/l), or both, before 12 weeks gestation or at least 6 weeks after delivery. DESIGN: Retrospective cohort study. SETTING: Nested on a community trial Delaying the Development of Diabetes Mellitus type 2 (AMAL study) in Oman. POPULATION: 532 women with a total of 3,196 pregnancies. METHODS: We conducted sets of Cox proportional hazard regression analyses: crude, age-adjusted and full models which adjusted for maternal age, education, family income and year of delivery. MAIN OUTCOME MEASURES: Hazard ratio (HR) of the effect of parity on prediabetes. RESULTS: We enumerated 258 cases of prediabetes over 8,529 person-years of follow up. In the crude model, high parity (> or =5) pregnancies carried a higher risk of prediabetes than low parity (<5) pregnancies (HR = 3.72; 95% CI = 2.80, 4.91), and the prediabetes incidence rate increased in a dose-response fashion over multiple categories of parity. In age-only models, the association attenuated with control of the confounding effect of maternal age (HR = 1.05; 95% CI = 0.76, 1.45). Adjusting for other confounders in the full models yielded similar results to those adjusted for maternal age only. CONCLUSIONS: The apparent effect of parity on the occurrence of prediabetes is attributable to the confounding effect of maternal age rather than to high parity.

RESUMO

BACKGROUND: Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by core deficits in social interactions, verbal/nonverbal communication, and restricted, repetitive, and stereotyped behaviors. Children with ASD are known to have several feeding problems that are believed to affect their nutritional and health status. AIM: The present study was designed to assess the food preferences in Omani children diagnosed with ASD compared with controls. METHODS: A case-control study was conducted in which 375 children (males and females) aged between 4 and 13 years were recruited. The sample consisted of 163 children with ASD and a control group of 212 typically developing (TD) children. For each participant, demographic, anthropometric, and medical information and information regarding dietary intakes were gathered using the food frequency questionnaire (FFQ) to assess their food preferences. RESULTS: The sociodemographic characteristics of caregivers were similar in the two groups, while their perceptions based on several nutritional parameters were different. Children's age and body mass index (BMI) were similar in both groups, while the number of male children was higher in ASD group (P < 0.001). Problematic behaviors including food refusal and selectivity were significantly higher in ASD children than in TD children. Despite that, the children with ASD were found to consume mostly traditional Omani dishes. CONCLUSION: This is the first study that provides information on the eating habits and nutritional intake of Omani children diagnosed with ASD. The overall findings are promising and may contribute to further understanding of food preferences in children with ASD in Oman. Such information is highly valuable for the prevention and management of nutritional deficiencies among Omani children with autism by improving their diet quality.

RESUMO

AIM: To explore the prevalence and correlates of depressive symptoms among parents/primary care providers of children with autism spectrum disorder (ASD). DESIGN AND METHODS: A cross-sectional analytical study was conducted among a systematic random sample of parents/caregivers of children with diagnosis of ASD in Muscat, Oman. Depressive symptoms were quantified using the Patient Health Questionnaire-9. FINDINGS: The response rate was at 86% (n = 80) and the prevalence of depressive symptoms, at 71.3% (95% confidence interval, 60.5-80.1). Logistic regression analyses indicated that unemployment and being the sole parent/caregiver in the family were both significant correlates of depressive symptoms. PRACTICE IMPLICATIONS: With an increase in the number of children being diagnosed with ASD, multidimensional preventive and remedial service programs for parents/caregivers will be essential.

RESUMO

PURPOSE: Literature emerging from Western countries has reported increased levels of serum oxidative stress markers among polycystic ovarian syndrome (PCOS) women. In the Arab region, there is limited research about the association between oxidative stress and PCOS. This study aimed to compare sociodemographic and clinical characteristics, sex hormones, and oxidative stress indices between PCOS women and non-PCOS women and to investigate the correlation between oxidative stress biomarkers and sex hormones. METHODS: This hospital-based case-control study was conducted among reproductive-aged women. The study included 51 women diagnosed with PCOS (as per Rotterdam 2003 criteria) and 45 control women who were not diagnosed with PCOS. Serum samples were collected to measure the mean levels of the following sex hormones: total testosterone, dehydroepiandrosterone sulfate, estradiol and progesterone, as well as to measure biomarkers of oxidative stress including glutathione peroxidase (GPx), glutathione reductase (GR), glutathione (GSH), and total antioxidant capacity (TAC). RESULTS: PCOS women exhibited clinical characteristics including irregular menses, hirsutism, and acne compared to the control group (P≤0.05). Significant differences were observed in the waist-hip ratio of PCOS women compared to controls (P=0.004). GPx and GR activity levels appeared to be higher among PCOS women compared to controls; however, no statistically significant differences were observed between the two groups (P>0.05). PCOS women had lower GSH and TAC levels compared to controls with a statistically significant difference observed for GSH levels (P=0.006). Correlation analysis showed a significant negative correlation between estradiol and TAC in the total sample (r=-0.284, P=0.005). CONCLUSION: This study provides supportive evidence that oxidative stress might play a role in the pathogenesis of PCOS and, hence, oxidative stress parameters could be suggested as diagnostic markers for early diagnosis of high-risk groups. Also, the study provides supportive evidence that obesity and sex hormones, particularly estradiol, in PCOS may contribute to enhanced oxidative stress.

RESUMO

PURPOSE: Previous studies in Euro-American populations have shown that women with polycystic ovarian syndrome (PCOS) have increased levels of "psychological burden". While PCOS has been reported in Arab countries such as Oman, there is a dearth of studies of the occurrence of psychological burden among PCOS women in the Arab region. This study aimed to compare sociodemographic and clinical characteristics of PCOS women diagnosed with non-PCOS women and prevalence of severity of depression, anxiety and stress and to explore the association between PCOS and indices of psychological disturbances after adjusting for potential confounding factors. PATIENTS AND METHODS: This hospital-based case-control study was conducted among women aged 16-49 years. The study included 52 women diagnosed with PCOS (as per Rotterdam 2003 criteria) and 60 control who were PCOS-free. The presence of psychological burden - depression, anxiety and stress - was quantified using Depression, Anxiety and Stress Scale-21 (DASS-21). RESULTS: The crude odds ratios (ORs) generated by logistic regression models indicated an increased risk of depression, anxiety and stress among women with PCOS compared to controls. The adjusted OR also indicated an increased risk of depression (OR =1.10; 95% confidence interval [CI] 0.50, 2.43), anxiety (OR =1.09; 95% CI 0.47, 2.52) and stress (OR =1.45; 95% CI 0.68, 3.12), However, no statistical differences were observed along the three psychological distresses (p>0.05) between the two study groups. CONCLUSION: The study indicates that the presence of PCOS is associated with an increased risk of psychological burden. If this study will withstand further scrutiny, meeting psychological needs of such population would need to be contemplated.
