Background: The peroxisome proliferator-activated receptors (PPARs) are members of the nuclear hormone receptor subfamily of transcription factors. It has been reported that they play important roles in obesity and the development of type 2 diabetes mellitus (T2DM). Materials and Methods: This case-control study was carried out among 764 Qatari patients with diabetes and 764 healthy subjects above 20 years of age at Primary Healthcare Clinics (PHCs) from January 2011 to December 2012. Face-to-face interviews were based on a questionnaire that included variables such as age, sex, sociodemographic status, body mass index (BMI) and other clinical parameters. The Pro12Ala in the PPARγ2 gene was detected on the LightCycler using two specific probes. Univariate and multivariate statistical analysis were performed. Results: The study revealed that in the diabetes group, Pro/(10.2% vs 9.4%; P = 0.606) and Ala/Ala (1.4% vs 0.9%; P = 0.343) were higher than in controls, whereas Pro/Pro (88.4% vs 89.7%;P = 0.413) was lower in diabetes patients, but no significant difference was observed among the genotype groups. In obese patients with diabetes, Pro/Pro (89% vs 89.9%;P = 0.792) and Pro/Ala (8.9% vs 10.1%;P = 0.671) were lower than in obese healthy subjects. No homozygous Ala/Ala was found in obese healthy subjects, whereas 6 Ala/Ala homozygotes were in obese diabetes group. But in diabetes group, obese patients had higher homozygous of Pro/Pro (89.3% vs 87.8%;P = 0.523) and Ala/Ala (1.8% vs 1.2%;P = 0.771) compared to non-obese patients. Conclusion: The current study did not reveal an association between the Pro12Ala polymorphism of the PPAR γ2 gene and type 2 diabetes (T2D) in Qatari's population.

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 (

OBJECTIVES: to investigate the relationship between the interpregnancy interval and low birth weight and other pregnancy outcomes. METHODS: this case-control study was carried out in hospitals from January 2010 to April 2011. For cases, mothers of 1216 newborns with birth weight2500 g were approached and 854 mothers participated in this study (73.7%). Face-to-face interviews were conducted to complete the questionnaires. RESULTS: of the newborn babies with low birth weight, the risk was higher among mothers with a short interpregnancy interval (40.3%), whereas for infants with normal birth weight, the majority of the mothers had a longer interpregnancy interval of 24 months (44.7%). A short interpregnancy interval of 612 months was more common among women of 2500 g, participaram 854(73,7%). Para completar os questionários, foram conduzidas entrevistas face a face. RESULTADOS: dos recém-nascidos com baixo peso, o fator de risco foi mais alto entre as mães com curto intervalo intergestacional (40,3%), enquanto para recém-nascidos com peso normal a maioria das mães tinham uma boa margem de intervalo intergestacional de 24 meses (44,7%). Curtos intervalo intergestacional (6 a 12 meses) foi mais comum entre mulheres de
