Clinical studies on seroprevalence of rubella virus in pregnant women of Cameroon regions

A study was conducted to investigate the seroprevalence of the rubella virus amongst pregnant women and the relationship it has with the duration of pregnancy, premature delivery, and past history of abortion in pregnant women visiting the Yaoundé Gynecological, Obstetric and Pediatric Hospital (HGOPY). 211 pregnant women attending the prenatal consultation of mean age 27±5.99 years were randomly selected and screened for rubella IgG antibodies. 39.3% of them were in their third trimester of pregnancy while 25.6% and 35.1% were in their first and second trimester of pregnancy respectively. 11.73% of the women had a history of premature delivery and 40.3% had a history of at least one abortion. Spearman's correlation was calculated between antibody titre and age. 88.6% of pregnant women were seropositive while 9% (susceptible) were seronagative and 2.4% had equivocal results. The most susceptible women to rubella infection were in the age group 26-30 years while women in the age group 21-25 years band were the most seropositive. There was a strong correlation between the antibody titre and age (r=0.549 p<0.01). There was no statistical difference between the pregnancy in trimesters and antibody titres (p=0.0926) as well as between the number of previous abortions and the antibody titre (p<0.01, r=0.246). No correlations between antibody titre and pregnancy duration, or occurrence of premature births. There was a weak correlation between the antibody titre and number of previous abortions

Relationship between parental socio-economic status and casual blood pressure in coastal nigerian adolescents

BACKGROUND: Emerging data suggest that essential or primary hypertension occurs in the young. Parental socioeconomic status may play a role but the exact mechanisms still remain unclear. OBJECTIVE: This study was aimed at determining the relationship between parental socioeconomic status and casual blood pressure in adolescents. METHODS: One thousand and eight adolescents attending two secondary schools in Calabar; Nigeria were selected by stratified random sampling. Their blood pressure; weights and heights were taken using standard methods and sociodemographic data were obtained using a pretested semistructured questionnaire. RESULTS: Blood pressure was increased with age with males having higher values. The other major determinants of blood pressure were weight; height; body mass index; level of physical activity and parental socioeconomic status (p 0.05). Female adolescents with parents in the lower socioeconomic classes had significantly higher systolic and diastolic blood pressure (p 0.05). In contrast; parental socioeconomic status showed no significant relationship with systolic blood pressure and diastolic blood pressure in males (p 0.05).The prevalence of elevated blood pressure was higher in females than in males. CONCLUSION: Low parental socioeconomic status appear to be associated with higher casual blood pressure especially in female coastal Nigerian adolescents. Traditional determinants did not appear to play a significant role. Psychological stress arising from environmental and economic stressors may be responsible
