Prevalence of asthma among the adult general population of five Middle Eastern countries: results of the SNAPSHOT program.

BACKGROUND: Asthma is a common chronic respiratory disease leading to morbidity, mortality and impaired quality of life worldwide. Information on asthma prevalence in the Middle East is fragmented and relatively out-dated. The SNAPSHOT program was conducted to obtain updated information. METHODS: SNAPSHOT is a cross-sectional epidemiological program carried out in five Middle Eastern countries (Egypt, Turkey, Kuwait, Saudi Arabia, and the United Arab Emirates, the latter three grouped into a Gulf cluster) to collect data on asthma, allergic rhinitis, benign prostatic hyperplasia and bipolar disorder. The survey was carried out by telephone in a random sample of the adult general population with quotas defined according to country demographics. The analysis presented in this paper focuses on asthma. Subjects were screened for asthma based on criteria from the global Asthma Insights and Reality studies. Current prevalence (last 12 months) was estimated. Multivariate logistic regression analyses were used to investigate risk factors related to asthma and the association with allergic rhinitis and other co-morbidities. Quality of life was assessed using the three-level EQ-5D questionnaire. RESULTS: 2124 out of the 33,486 subjects enrolled in the SNAPSHOT program fulfilled the criteria for asthma. The adjusted prevalence of asthma ranged from 4.4% [95% CI: 4.0-4.8%] in Turkey, to 6.7% [95% CI: 6.2-7.2%] in Egypt and 7.6% [95% CI: 7.1-8.0%] in the Gulf cluster. Prevalence was higher (p < 0.0001) in women than men and increased with age (p < 0.0001). Co-morbidities occurred more frequently in asthma subjects compared to the non-asthma population (38% vs. 15% p < 0.0001). Subjects with asthma reported a lower (p < 0.0001) EQ-VAS score (68.2 ± 22.9) compared to the general population (78.1 ± 17.5). The risk factors associated with asthma were age, gender, country, and certain co-morbidities, namely respiratory, cardiovascular, gastrointestinal, nervous, and neurological diseases. CONCLUSION: The observed adjusted prevalence of asthma in the Middle East ranges from 4.4% to 7.6%, which is comparatively lower than the reported prevalence in Europe and North America. Asthma has a negative impact on quality of life, and is associated with high levels of co-morbid diseases, indicating a need for physicians to check for co-morbidities and ensure they are managed correctly in all asthma patients.

Prevalence of benign prostatic hyperplasia among the adult general population of five Middle Eastern Countries: Results of the SNAPSHOT programme.

OBJECTIVES: To present data on the prevalence of benign prostatic hyperplasia (BPH) in five Middle Eastern countries (Egypt, Turkey, Kuwait, Saudi Arabia, and the United Arab Emirates; the latter three forming a Gulf cluster). SUBJECTS AND METHODS: The SNAPSHOT programme was a multi-country, cross-sectional epidemiological survey conducted by telephone in a random sample of the adult general population. Subjects were considered to have BPH if they fulfilled the screening criteria, based on diagnosis, symptoms, and treatments received in the past 12 months. Current prevalence (last 12 months) was estimated. Association with co-morbidities was investigated via multivariate logistic regressions. Quality of life (QoL) was assessed using the three-level EuroQol five-dimensions questionnaire (EQ-5D-3 L). RESULTS: In total, 5034 of 33,486 subjects enrolled in the SNAPSHOT programme were men aged ≥50 years. In all, 998 of these men fulfilled the BPH screening criteria. The overall prevalence of BPH ranged from 13.84% (95% confidence interval[CI] 12.3-15.4%) in Turkey, to 23.76% (95% CI 21.8-25.6%) in Egypt, and 23.79% (95% CI 21.2-26.3%) in the Gulf cluster. Co-morbidities occurred more frequently in men with BPH compared to the non-BPH population (57% vs 31%; P < 0.001). Principal co-morbidities associated with BPH were cardiovascular, renal, and diabetes mellitus (P < 0.001). The men with BPH reported significantly reduced QoL, with lower EQ-5D-3 L utility values (0.8) compared to the male general population (0.9) aged ≥50 years (P < 0.001). CONCLUSION: The prevalence of BPH in these five Middle Eastern countries ranges from 13.84% to 23.79%. BPH has a negative impact on QoL and is associated with high levels of co-morbid diseases, indicating a need to better understand the management of the disease to reduce the impact on healthcare systems.

The clinical burden of allergic rhinitis in five Middle Eastern countries: results of the SNAPSHOT program.

BACKGROUND: The SNAPSHOT program provides current data on the allergic rhinitis burden in the adult general population of five Middle Eastern countries (Egypt, Turkey, Kuwait, Saudi Arabia and the United Arab Emirates, the latter three grouped into a Gulf cluster). METHODS: A multi-country, cross-sectional, epidemiological program conducted by telephone in a random sample of the adult general population; quotas were defined per country demographics. Subjects were screened for allergic rhinitis using the Score For Allergic Rhinitis questionnaire. Current prevalence (last 12 months) was estimated. Disease severity and control were assessed using the Allergic Rhinitis and its Impact on Asthma classification and Rhinitis Control Assessment Test respectively. Quality of sleep, impact on daily activities and quality of life were measured using the Epworth Sleepiness Scale, Sheehan Disability Scale and EuroQol Five-Dimension questionnaire respectively. Multivariate logistic regression analyses were used to investigate risk factors and co-morbidities. RESULTS: 1808 of 33,486 subjects enrolled in the SNAPSHOT program fulfilled the case definition for allergic rhinitis. Prevalence was 3.6% [95% CI 3.2-4.0%] in Egypt, 6.4% [95% CI 5.9-6.9%] in Turkey and 6.4% [95% CI 6.0-6.9%] in the Gulf cluster. Risk factors identified were country, co-morbid asthma and income. Subjects with allergic rhinitis reported a significantly lower quality of life compared to the general population (p < 0.0001). Overall, 55% of allergic rhinitis subjects were moderate/severe and 33% were uncontrolled. Both these groups reported impaired quality of life and quality of sleep and increased impairment of daily activities compared to mild/well-controlled subjects (p < 0.0001). CONCLUSIONS: Although the observed prevalence of allergic rhinitis in these Middle Eastern countries is low compared to western countries, its burden is considerable. Allergic rhinitis in general, and specifically uncontrolled and severe disease, results in a negative impact on quality of life, quality of sleep and daily activities.

Burden of disease associated with asthma among the adult general population of five Middle Eastern countries: Results of the SNAPSHOT program.

BACKGROUND: Asthma affects millions worldwide resulting in a significant disease burden. However, data on asthma burden from the Middle East is limited. This analysis describes the asthma burden in Egypt, Turkey and a Gulf cluster (Kuwait, Saudi Arabia and United Arab Emirates) as part of the SNAPSHOT program. METHODS: SNAPSHOT was an observational, cross-sectional program carried out by telephone in a random sample of the adult general population of the five above mentioned countries. Quotas were defined per country demographics. Subjects were considered to have asthma if they fulfilled the screening criteria, based on the global Asthma Insights and Reality studies. Data collected included demographics, physician consultations, and asthma control (measured by the Asthma Control Test; ACT). Quality of life was assessed using the EuroQol Five-Dimension questionnaire (EQ-5D); and limitations to daily activities using the modified Sheehan Disability Scale (SDS). RESULTS: 939 subjects answered questions related to asthma burden. Overall, 367 (44.2%) reported uncontrolled asthma (ACT≤19), and reported significantly lower EQ-5D-3L utility values (0.6 ±â€¯0.4) and EQ-VAS scores (60.7 ±â€¯24.2) compared to controlled subjects (0.8 ±â€¯0.3 and 75.3 ±â€¯19.8 respectively) (p < 0.0001). A significantly higher proportion with uncontrolled asthma also reported experiencing impact on activities of daily living compared to subjects with controlled asthma (p < 0.0001). Overall, 355 (37.8%) asthma subjects were followed by a physician. However, most visits were unscheduled (695;78.0%). CONCLUSION: Uncontrolled asthma imposes a significant burden in these Middle Eastern countries resulting in increased frequency of healthcare use, lower quality of life, and a higher impact on daily life compared to controlled asthma.

Adherence to COPD treatment in Turkey and Saudi Arabia: results of the ADCARE study.

BACKGROUND: COPD affects millions of people worldwide. Poor treatment adherence contributes to increased symptom severity, morbidity and mortality. This study was designed to investigate adherence to COPD treatment in Turkey and Saudi Arabia. METHODS: An observational, cross-sectional study in adult COPD patients in Turkey and Saudi Arabia. Through physician-led interviews, data were collected on sociodemographics and disease history, including the impact of COPD on health status using the COPD Assessment Test (CAT); quality of life, using the EuroQol Five-Dimension questionnaire (EQ-5D); and anxiety and depression using the Hospital Anxiety and Depression Scale (HADS). Treatment adherence was measured using the 8-item Morisky Medication Adherence Scale (MMAS-8). Multivariate logistic regression analysis examined the predictors of non-adherence and the impact of adherence on symptom severity. RESULTS: Four hundred and five COPD patients participated: 199 in Turkey and 206 in Saudi Arabia. Overall, 49.2% reported low adherence (MMAS-8 <6). Of those, 74.7% reported high disease impact (CAT >15) compared to 58.4% reporting medium/high adherence (p=0.0008). Patients with low adherence reported a lower mean 3-level EQ-5D utility value (0.54±0.35) compared to those with medium/high adherence (0.64±0.30; p<0.0001). Depression with HADS score 8-10 or >10 was associated with lower adherence (OR 2.50 [95% CI: 1.43-4.39] and 2.43 [95% CI: 1.39-4.25], respectively; p=0.0008). Being a high school/college graduate was associated with better adherence compared with no high school (OR 0.57 [95% CI: 0.33-0.98] and 0.38 [95% CI: 0.15-1.00], respectively; p=0.0310). After adjusting for age, gender, and country, a significant association between treatment adherence (MMAS-8 score ≥6) and lower disease impact (CAT ≤15) was observed (OR 0.56 [95% CI: 0.33-0.95]; p=0.0314). CONCLUSION: Adherence to COPD treatment is poor in Turkey and Saudi Arabia. Non-adherence to treatment is associated with higher disease impact and reduced quality of life. Depression, age, and level of education were independent determinants of adherence.

The development of a Local Index of Need (LIN) and its use to explain variations in social services expenditure on mental health care in England.

Wide variations in deprivation exist across England and it is likely that these variations translate into differences in the need for mental health care. Social Services Departments in England account for a substantial proportion of mental health expenditure. It is important that the distribution of expenditure reflects mental health needs. This paper's aims are to (1) describe the development of a new indicator of mental health needs, (2) use the index to explain variations in social services expenditure on mental health, and (3) compare the index with other established measures of need. A principal components analysis of sociodemographic variables considered to be indicators of need was used to produce four distinct factors for 148 Local Authority areas in England. A weighted sum of these factors was used to produce a single index. (Weights were the proportion of variance explained by each factor.) The index was used in a regression model to explain variations in spending on mental health care and was compared with (1) a model containing the four individual factors, (2) the current method of allocating resources, (3) the index used to allocate resources to primary care trusts, (4) the Mental Illness Needs Index (MINI), (5) four indices of deprivation produced by the Office of the Deputy Prime Minister, and (6) the average of the above four indices. The new index could explain 54% of variation, compared with 56% using the current method. The four-factor model could explain 66%, whilst the other models could explain between 37% and 20%. This new index has the advantage that it is not based on previous levels of utilisation or expenditure and yet still explains a comparable amount of variation as the current method. However, a disaggregated model containing individual factors may be preferable.
