Background/Aim:Since selective screening for Hepatitis B virus (HBV) in pregnant women has failed to identify a high proportion of HBV-infected mothers, pre-natal HBsAg testing of all pregnant women is now recommended. We aimed to determine the prevalence of HBV infection among pregnant women at the ante-natal clinic of a tertiary care center in Saudi Arabia and to identify the target group for postpartum immunization.Materials and Methods:A total of 755 pregnant females who attended the antenatal clinic from June 2005 to June 2006 for the first time - before 38 weeks of gestation - constituted the target of the present study. Blood samples 30-39 were drawn from all subjects and sera were tested for HBV serologic markers including Hepatitis B surface antigen, anti-HBs, and anti-HBc using ELISA technique (third generation).Results:The overall prevalence of sero-positive HBsAg among pregnant women was 1.6%. As age increased, the prevalence of sero-positive HBsAg significantly increased (χ2 = 116.43, P < 0.001), 30–39 were women aged ≥40 were five times more likely to be positive for HBsAg as compared to those <30 years (OR = 4.78). On the other hand, women aged 40 and over were five times more likely to be susceptible to infection with hepatitis as compared to young women aged <20 (OR = 5.15). Women susceptible to HBV infection constituted about 80% of all pregnant females.Conclusion:These findings reflect that the full impact of the Hepatitis B vaccination program that was conducted in 1989 for all Saudi children has not yet reached all pregnant women, with the majority (79.9%) being nonimmune and thus liable to HBV infection. Postpartum HB immunization should be recommended in such cases.
A study in Riyadh, Saudi Arabia investigated the prevalence of gestational diabetes mellitus (GDM) and its predictors in a high-parity group of pregnant women (n = 633, 50.1% grand multiparas). The prevalence of GDM was 12.5% and 3.8% by World Health Organization and American Diabetes Association criteria respectively.Multiparous women were 8.29 times more likely to have GDM than nulliparous women. However, after adjustment for maternal age and history of abortion, nulliparous women were 2.95 times more likely to develop GDM than parous women. The probability of GDM for a parous woman increased from 2% to 21% when age increased from 20 to 40 years. The high rate of GDM among grand multiparas may be due to the confounding effect of maternal age.
Aim. (i) To estimate the prevalence of the metabolic abnormalities among Saudi college students in Riyadh, Saudi Arabia, and (ii) to investigate the association between different indicators of body composition and these abnormalities. Methods. A total of 501 college students participated in a cross-sectional study. Anthropometric assessments, BP measurements, and biochemical assessment were done. Metabolic abnormalities were identified. Results. Applying BMI, 21.9 % and 20.6% of students were classified as overweight and obese, respectively. Central obesity was prevalent in 26.9% and 42.2% of students based on WC and WHtR, respectively. Other metabolic abnormalities were hypertension (23.6%) and abnormal FPG level (22.6%). Three or more abnormalities were prevalent in 7.8% of students and increased significantly to 26.4%, 20%, and 17.6 in obese subjects based on BMI, WC, and WHtR, respectively. With the exception of abnormal FPG, prevalence of individual metabolic abnormalities as well as the number of these abnormalities significantly increased with increasing BMI, WC, and WHtR (P < 0.001 each).
Conclusion. Our findings provide evidence for the presence of MS in Saudi college students. Central adiposity contributes to the high incidence of individual MS components. College health programs that promote healthful lifestyle and avoidance of adult weight gain are recommended.
