RESUMEN

This cross-sectional case-control study was undertaken to determine the prevalence of anticardiolipin antibodies [ACA] among non-pregnant women, normal pregnancy and complicated pregnancy. The sample was selected from three groups. Group A; non-pregnant women, Group B; healthy pregnant women and Group C included complicated pregnancies. All patients had an initial screening for A CA levels [qualitative assessment]. Those who tested positive or borderline were retested [quantitative assessment] after an interval of at least 8 weeks. Data of 496 women were analyzed. Fifty-two [10.5%] women had a previous complicated pregnancy of the total 496 women only five [1%] were positive for either IgG or IgM. Only one [0.2%] tested strongly positive [IgM]. The prevalence of A CA was 0.6% for group A and 1.2% for group B and C. The difference was not statistically significant. In conclusion, this study suggests that the prevalence of A CA in very low in this population. Prenatal complications were not associated with ACA status. The use of prophylactic anticoagulants should be based on confirmed laboratory diagnosis

RESUMEN

The objective of this cross sectional survey was to study the feasibility of conducting research on issues related to physical and sexual maturation in a predominantly Islamic society and to identify the factors influencing menarche in this multi ethnic community. This study was conducted in Al-Ain, United Arab Emirates [UAE] between January 1999 through to February 1999. Fifteen female secondary schools located in different geographical regions in Al-Ain were chosen in consultation with the District Education Department. All girls aged 12-16-years were selected. Information regarding whether they had attained menarche including month and the year, age at menarche and the factors influencing it such as height and weight, diet, physical activity were gathered. Univariate and multiple linear regressions were used in analysis. Of the 1500 questionnaires distributed, 1416 questionnaires were returned but only 890 had the required information and were used in the analysis. Ninety-three [10.4%] had not attained menarche and as expected these girls were younger [p<0.0001] than those who had attained menarche. Mean age at menarche was 12.68 [SD 1.27] years. In the univariate analysis UAE nationality, vegetarians [p=0.001], higher income group [p=0.008], low body weight [p=0.009] and a diagnosis of anemia [p<0.05] in the year before menarche were all positively associated with the age at menarche. Only anemia achieved borderline significance [p=0.056] in multivariate analysis and no other variables were significant. This study highlights the difficulties of conducting research on issues considered to be sensitive by the community and provide data on factors influencing menarche in a multi ethnic community
