Maternal complications and neonatal outcome in Arab women of a fast developing country.

OBJECTIVE: The objective of the study was to examine maternal complications that occur during the third trimester and their neonatal outcome in Arab women residing in Qatar. DESIGN: This is a prospective hospital-based study. SETTING: The survey was carried out in women's hospital. MATERIALS AND METHODS: The study was based on the log book of the women's hospital, from which we recruited women in their third trimester of pregnancy between the first week of January 2010 and April 2011. Of the 1 824 Arab women who were approached to participate in the study, 1 432 (78.5%) consented. Face-to-face interviews were conducted with the pregnant women in the third trimester attending routine antenatal clinics at a women's hospital. The questionnaire covered variables related to sociodemographic factors, family history, medical history, maternal complications, and neonatal outcome. Medical records of the patients were referred to collect the clinical variables. RESULTS: Of the pregnant women studied, 39.8% were less than 30 years of age. The risk of maternal complications was higher in housewives (60.8%) and women with a low monthly household income (38.2%). Most of the pregnant women (77.6%) had antenatal care. Normal delivery (69.7%) was more common in expatriate Arab women, whereas caesarean was more prevalent in Qatari women (22.2%). Women aged 35 years or older had a significantly higher risk of maternal complications such as gestational diabetes (20.8% vs 13.4%; P < 0.01), gestational hypertension (21.6% vs 15.2%; P = 0.003), and ante-partum hemorrhage (17.9% vs 13.7%; P = 0.042) than younger women. Gestational diabetes increased the risk of caesarean delivery (25.1%) and macrosomia (42.3%). The frequency of caesarean delivery (22.1%) was higher in women with gestational hypertension. Neonatal complications such as Apgar score (<7) 1 minute (33.1% vs 21.2%; P < 0.001), 5 minutes (13.1% vs 8.2%; P = 0.005), and congenital anomalies (2.9% vs 0.9%; P = 0.007) were significantly higher in newborns of older women. Low birth weight (11.1%) and Apgar 1(st) minute < 7 rate (28.2%) were higher in newborns of mothers with ante-partum hemorrhage. CONCLUSION: The study findings revealed that maternal complications such as gestational diabetes, gestational hypertension, ante-partum hemorrhage, and maternal anemia were significantly higher in older pregnant women. Similarly, neonatal complications were higher in the newborns of older women. Gestational hypertension was the leading maternal complication observed in Arab women.

Obesity and low vision as a result of excessive Internet use and television viewing.

The technological age has resulted in children spending prolonged hours in front of television (TV) and computer screens (on the Internet). The aim of this prospective cross-sectional study is to determine the effect of this phenomenon on both childhood obesity and low vision in the State of Qatar. A total of 3000 school students aged 6 to 18 years were approached from September 2009 to March 2010 and 2467 (82.2%) students agreed to participate. Face-to-face interviews based on a designed questionnaire were conducted. The highest proportion of obese children were aged between 15-18 years (9.4%; p < 0.001); spent ≥ 3 hours on the Internet (5.6%; p < 0.001), and spent between 5-7 hours or less sleeping (4.1%; p < 0.001). Forty-six (1.9%) children spent ≥ 3 hours/day on the Internet, and were either overweight/obese and had low vision. The study findings confirmed a positive association between obesity and low vision as a result of excessive time spent on the TV view and Internet use.

Do excessive internet use, television viewing and poor lifestyle habits affect low vision in school children?

The aim of this study is to determine whether excessive internet use, television viewing and the ensuing poor lifestyle habits affect low vision in school children in a rapidly developing country. This is a cross-sectional study and 3000 school students aged between six and 18 years were approached and 2467 (82.2%) students participated. Of the studied school children 12.6 percent had low vision. Most of the low vision school children were in the 6-10 years age group and came from middle income backgrounds (41.8%; p = 0.008). A large proportion of the children with low vision spent ≥ 3 hours per day on the internet (48.2%; p< 0.001) and ≥ 3 hours reclining (62.4%; p < 0.001). A significantly smaller frequency of studied children with low vision participated in each of the reviewed forms of physical activity (p < 0.001) yet a larger proportion consumed fast food (86.8%; p < 0.001). Highly significant positive correlations were found between low vision and BMI, hours spent reclining and on the internet respectively. Blurred vision was the most commonly complained of symptom among the studied children (p < 0.001). The current study suggested a strong association between spending prolonged hours on the computer or TV, fast food eating, poor lifestyle habits and low vision.

Impact of consanguinity on cancer in a highly endogamous population.

BACKGROUND: Many epidemiological studies have indicated that inbreeding has little or no effect on the incidence of cancer. Due to the high prevalence of consanguinity in Qatar (54%), its influence may nevertheless be of special importance. AIM: The aim of this study was to examine whether parental consanguinity affects the risk of cancer in a local Arab highly inbred population. DESIGN: Matched case-control study. SETTING: The study was carried out in Al-Amal cancer hospital and primary health care centers in Qatar over a period from August 2008 to February 2009. SUBJECTS AND METHODS: The study included 370 Qataris and other Arab expatriates with various types of cancers and 635 controls matched by age and ethnicity. A questionnaire that included socio-demographic information, type of consanguinity, medical history, and tumor grade was designed to collect the information of cases and controls. RESULTS: The study revealed that the rate of parental consanguinity was similar in both cases (29.5%) and controls (29.9%) with a higher inbreeding coefficient in controls (0.017-/+0.03), compared to cancer patients (0.0155-/+0.03). Other Arab expatriates had a higher incidence of cancer (61.1%) than Qataris (38.9%). The inbreeding coefficient was higher in male cancer patients (0.0189-/+0.03), but lower in female cancer patients (0.014-/+0.03) as compared to controls. Controls were more inbred in the overall studied subjects (23.6%) and women (23.8%) than cases. The coefficient of inbreeding was lower in patients with breast (0.014), skin (0.012), thyroid (0.008) and female genital (0.014) cancers, whereas it was higher in cases for leukemia and lymphoma (0.018), colorectal (0.025) and prostate (0.017), with no significant difference between cases and controls. No significant differences were observed between cases and controls in the parental consanguinity, mean coefficient of inbreeding and proportion of more inbred subjects. CONCLUSIONS: The study findings revealed that although the consanguinity rate is high in our Arab population, it has no effect on the incidence of cancers overall. However, there was an increased risk found for leukemia and lymphoma, colorectal and prostate cancer groups, but a reduced risk in breast, skin, thyroid and female genital cancer groups.
