Correlates of Smoking, Quit Attempts and Attitudes towards Total Smoking Bans at University: Findings from Eleven Faculties in Egypt

OBJECTIVES Smoking among university students represents a formidable and global public health challenge. We assessed the associations between socio-demographic, health and wellbeing variables as independent variables, with daily smoking, attempts to quit smoking, and agreement with smoking ban as dependent variables. METHODS A sample of 3258 undergraduate students from eleven faculties at Assiut University, Assiut, Egypt, completed a general health questionnaire. RESULTS Overall daily or occasional smoking in last three months prior to the survey was about 9% (8% occasional and 1% daily smokers), and smoking was generally more prevalent among males (male=17%, female=0.6%, P < 0.001). After adjustment for confounders, not having normal BMI and having a mother who completed at least bachelors degree education was positively associated with daily smoking, and conversely, no history of illicit drug use was a protective factor. About 76% of smokers had attempted to quit smoking within the last 12 months prior to the survey. Although a large proportion of students agreed/ strongly agreed with the banning of smoking at university altogether (87%), such agreement was less likely among smokers. CONCLUSION There is need for implementation of non-smoking policies on university premises, as well as regular up-to-date information on, and the periodic/yearly monitoring of tobacco use by university students employing standardised data collection instruments and reference periods. In addition, it would be valuable to develop campus-based educational/ awareness campaigns designed to counteract tobacco advertisement directed towards young people in Middle East countries. Otherwise, the danger could be that the current relatively low smoking prevalence among university students may escalate in the future.

A Cross “Ethnical” Comparison of the Driver Behaviour Questionnaire (DBQ) in an Economically Fast Developing Country

Aim: The aim of this study was to compare the driving behaviours of four ethnic groups and to investigate the relationship between violations, errors and lapses of DBQ and accident involvement in Qatar. Subjects and Methods: The Driver Behaviour Questionnaire (DBQ) was used to measure the aberrant driving behaviours leading to accidents. Of 2400 drivers approached, 1824 drivers agreed to participate (76%) and completed the driver behaviour questionnaire and background information. Results: The study revealed that the majority of the Qatari (35.9%) and Jordanian drivers (37.5%) were below 30 years of age, whereas Filipino (42.3%) and Indian subcontinent (34.1%) drivers were in the age group of 30-39 years. Qatari drivers (52%) were involved in most accidents, followed by Jordanians (48.3%). The most common type of collision was a head on collision, which was similar in all four ethnic groups. The Qatari drivers scored higher on almost all items of violations, errors and lapses compared to other ethnic groups, while Filipino drivers were lower on all the items. The most common violation was the same in all four ethnic groups “Disregard the speed limits on a motorway”. The most common error item observed was “Queing to turn right/left on to a main road”. “Forget where you left your car” and “Hit something when reversing” were the two lapses identified in factor analysis. Conclusion: The present study identified that Qatari drivers scored higher on most of the items of violations, errors and lapses of DBQ compared to other countries, whereas Filipino drivers scored lower in DBQ items.

Pattern of Maternal Complications and Low Birth Weight: Associated Risk Factors among Highly Endogamous Women

Objective. The objective of the study was to examine the pattern of low birth weight LBW, maternal complications, and its related factors among Arab women in Qatar. Design. This is a prospective hospital-based study. Setting. The study was carried out in Womens Hospital, Doha. Subjects and Methods. Pregnant women in their third trimester were identified in the log book of Womens Hospital and recruited into the study during first week of January 2010 to July 2011. Only 1674 (out of 2238) Arab women (74.7%) consented to participate in this study. Data on clinical and biochemistry parameters were retrieved from medical records. Follow-up data on neonatal outcome was obtained from labor room register. Results. The incidence of LBW (<2500 g) was 6.7% among Arab women during 2010 in Qatar. Distribution of gestational diabetes mellitus (GDM), antepartum hemorrhage (APH), maternal anemia, premature rupture of membrane (PROM), maternal occupation, parity, sheesha smoking, and parental consanguinity were significantly different (P < 0.05) between mothers of LBW and normal birth weight NBW (≥2500 g) babies. Multivariable logistic regression analysis revealed that previous LBW, consanguinity, parity, smoking shesha, GDM, APH, anemia, PROM, maternal occupation, and housing condition were significantly associated with LBW adjusting for gestational age. Conclusion. Maternal complications such as GDM, APH, anemia, PROM, and smoking shesha during pregnancy are significantly increasing the risk of LBW outcome. Screening and prompt treatment for maternal complications and health education for smoking cessation during routine antenatal visits will help in substantial reduction of LBW outcome.

Parental transmission of type 2 diabetes mellitus in a highly endogamous population

AIM To determine the parental transmission of diabetes mellitus (DM) and evaluate its influence on the clinical characteristics. METHODS This was a cross sectional study. The survey was carried out in urban and semi-urban primary health care centers. Of the 2400 registered with diagnosed diabetes, 1980 agreed and gave their consent to take part in this study, thus giving a response rate of 82.5%. Face to face interviews were conducted using a structured questionnaire followed by laboratory tests. DM was defined according to the World Health Organization expert group. A trained nurse performed physical examinations and measurements. RESULTS Of the study population, 72.9% reported a family history of DM. Family history of DM was significantly higher in females (54.2%; P = 0.04) and in the age group below 30 years (24%; P < 0.001). The prevalence of diabetes was higher among patients with a diabetic mother (25.4% vs 22.1%) and maternal aunts/uncles (31.2% vs 22.2%) compared to patients with a diabetic father and paternal aunts/uncles. Family history of DM was higher in patients of consanguineous parents (38.5%) than those of non-consanguineous parents (30.2%). The development of type 2 diabetes mellitus (T2DM) complications was higher in patients with either a paternal or maternal history of DM than in those without. No significant difference was observed in the metabolic characteristics of patients with/without family history of DM except for hypertension. Complications were higher in diabetic patients with a family history of DM. CONCLUSION The present study found a significant maternal effect in transmission of T2DM. Family history is associated with the increased incidence of diabetes.

Association of PPARγ2 gene variant Pro12Ala polymorphism with hypertension and obesity in the aboriginal Qatari population known for being consanguineous

Aim The aim of this study was to investigate the association of the Pro12Ala polymorphism of the human peroxisome proliferator-activated receptor gamma 2 (PPARγ2) gene with hypertension and obesity in a highly consanguineous aboriginal Qatari population. Design A cross-sectional survey conducted from January 2011–December 2012. Setting Primary health care clinics. Subjects A random sample of 1,528 Qatari male and female population older than 20 years of age. Materials and methods Data on age, sex, income, level of education, occupation status, body mass index, and blood pressure and lipid profile were obtained. The Pro12Ala in the PPARγ2 gene was detected on the LightCycler® using two specific probes: (Sensor [G] 5′-CTC CTA TTG ACG CAG AAA GCG-FL and PPAR Anchor 5′ LC Red 640- TCC TTC ACT GAT ACA CTG TCT GCA AAC ATA TC-PH). Univariate and multivariate logistic regression were performed. Result Out of a total 1,528 participants, 220 were diagnosed with essential hypertension, and 420 were obese. Participants with consanguinity were significantly higher among hypertensive than normotensive (41.9% versus 30.8%; P=0.001). Altogether, more than three-fourths (89%) of the participants had a wild genotype (Pro12Pro), 9.8% were heterozygous with Pro12Ala, and only 1.2% was homozygous with the Ala12Ala genotype. The frequency of the Pro allele was 94.5% in normotensive versus 90.5% in hypertensive, while the distribution of the Ala allele was 5.5% in normotensive versus 9.5% in the hypertensive group (P=0.001). The odds of hypertension were 1.7 times higher among the participants with the Ala allele as compared to those with the Pro, while adjusting for other potential confounders (adjusted odds ratio 1.69; 95% confidence interval 1.12–2.55; P=0.012). There was no association between the PPARγ2Ala allele and obesity (P=0.740). Conclusion The current study revealed an association between the PPARγ2Ala allele and hypertension in Qatar’s population. On the other hand, this study found no association between the Ala allele and obesity.

Hepatitis B vaccination among primary health care workers in Northwest Pakistan

BACKGROUND We assessed hepatitis B vaccination and its determinants among health care workers (HCW) in rural Northwest Pakistan. METHODS This cross sectional study was conducted among 485 HCWs from both public and private clinics. Data about hepatitis B vaccination, socio-demographic, knowledge regarding modes of transmission of hepatitis B virus, perceived disease severity and benefits of vaccination was collected through questionnaire. Multivariable logistic regression analysis was performed. RESULTS Prevalence of complete hepatitis B vaccination was 40% (among Physicians with MBBS/MD qualification; 86% and lowest among non-qualified Dispensers;16%). Also, prevalence was higher among HCWs from public Dispensaries (77%) than those working in private clinics (35%). Being MBBS/MD Physician (Adj. OR 26.60; 95%CI 9.27-73.23), Non-MBBS/MD Physician (Adj.OR 1.89; 95%CI 0.78-4.59), qualified Dispensers (Adj. OR 3.58; 95%CI 1.34-9.54) compared to non-qualified Dispensers, working in public clinics (Adj. OR 2.54; 95%CI 1.13-5.69) as compared to private, perceived disease threat after exposure to blood and body fluids (Adj. OR 1.11; 95%CI 1.03-1.19) and perceived benefits of hepatitis B vaccination (Adj. OR 1.13; 95%CI 1.09-1.19) were significant predictors of complete hepatitis B vaccination. CONCLUSION Improved perception of disease threat and benefits of vaccination and qualification of HCWs are associated with hepatitis B vaccination among Primary HCWs.

The national perinatal mortality rate in the State of Qatar during 2011; trends since 1990 and comparative analysis with selected high-income countries: The PEARL Study Project*

Abstract Objective: To prospectively ascertain Qatar’s national perinatal mortality rate (PMR) during 2011, compare it with recent data from selected high-income countries, and analyze trends in Qatar’s PMR between 1990 and 2011 using historical data. Study design: A national prospective cohort study. Methods: National data on live births, stillbirths, and early neonatal mortality (day 0–6) were collected from all public and private maternity units in Qatar (1st January–December 31st 2011) and compared with historical perinatal mortality data (1990–2010) ascertained from the database of maternity and neonatal units of Women’s Hospital and annual reports of Hamad Medical Corporation (HMC). For inter-country comparison, country data were extracted from the World Health Statistics published by WHO in 2011 and from the European Perinatal Health Report published by the Europeristat project in 2008. Results: A total of 20,725 births (20,583 live births plus 142 stillbirths) were recorded during the study period. Qatar’s national PMR during 2011 was 9.55 [early neonatal mortality rate (ENMR) 2.7 and stillbirth rate (SBR) 6.85], which was a significant improvement from a PMR of 13.2 in 1990 [risk ratio (RR) 0.72, 95% confidence interval 0.58–0.89, P=0.002]. This improvement in PMR was more significant in ENMR (P<0.001) than in SBR (P=0.019). The stillbirths constituted 55% of PMR in 1990, which increased to 71.72% of PMR during 2011. The RR of PMR had a significant downwards trend between 1990 and 2011 (P=0.016). Qatar’s 2011 PMR, SBR, and ENMR are comparable to those of selected high-income counties. Conclusions: Qatar’s PMR, ENMR, and SBR have significantly improved between 1990 and 2011, and are currently comparable to those of selected high-income countries. An in-depth research to assess the correlates and determinants of stillbirth and perinatal mortality in Qatar is indicated.

Have neonatal mortality rates in the state of Qatar become static? A PEARL study analysis

To ascertain the national neonatal mortality rate in Qatar during the first quarter of 2011 (1 January-31 March), we carried out a prospective pilot national epidemiologic study. Nationwide birth and neonatal mortality data were collected using predesigned, structured questionnaires. To analyse trends over the previous 4 years (2008-2011) we used neonatal mortality data for 2008-2010 from the database of the neonatal unit at the Womens Hospital, annual reports of Hamad Medical Corporation, and published neonatal mortality data for 2010 for comparative analysis. A total of 4909 live births and 21 neonatal deaths were recorded during the study period. The neonatal mortality rate was 4.28/1000 live births (corrected neonatal mortality rate 2.85/1000). The early neonatal mortality rate was 1.84/1000 and the late neonatal mortality rate was 2.44/1000 live births. Fifteen of the 21 neonatal deaths were in non-Qatari babies, reflecting the ethnic distribution in the population. Neonatal mortality rates in Qatar declined very little between 2008 and the first quarter of 2011.

Trends of Cause and Sex-Specific Mortality, and Its Impact on the Life Expectancy among Qatari Population

The study aimed to assess the changes in the cause and sex-specific mortality and the life expectancy in Qatar from 1996- 2010. Method: the electronic database, from the tertiary healthcare providers at the Hamad Medical Corporation (HMC), and vital health statistics from Supreme Council of Health in Qatar was utilized to assess the impact of cause and sex-specific mortality on life expectancy at birth. Correlation between life expectancy at birth to causes such as cardiovascular diseases (CVD), traffic accidents, malignant neoplasm, endocrine diseases and congenital abnormalities was measured, so as to compare the potential gains from the elimination of these causes. Result: in Qatar, considering the time period of 1996-2010, the gain in life expectancy at birth was 3.6 years for men and 2.3 years for women. Overall, all cause mortality rate was 176.7 per 100,000 during 1996-2010. The mortality related to circulatory system ranked first, with mean annual mortality rate of 38.7 per 100,000, followed by road traffic accidents (27.18). Among males, mean annual mortality due to traffic accidents and circulatory systems declined from 1996 to 2010. Among females, mean mortality rate due to neoplasm mildly increased from 20.0/100,000 in 1996 to 24.8/100,000 in 2010, and that due to prenatal conditions among females declined from 12.0/100,000 in 1996, to 6.9/100,000 in 2010. Among both males and females, the mean mortality for circulatory system declined during 1996 to 2010. Overall, except for road traffic accidents (r=-0.130, p=0.494), ill- defined conditions (r=-0.235, p= 0.212), and endocrine disease (r=-0.135, p=0.476) all other leading causes of mortality showed significant negative correlation with life expectancy at birth. Conclusion: increases in life expectancy in Qatar were mostly achieved by reductions in all causes mortality, and especially from reductions in mortality from the circulatory and endocrine system diseases, and prenatal and congenital deaths. The present study provided useful information which can help the policy makers in more effective allocation of resources for public health programs in Qatar.
