Neonatal Blood Pressure and Anthropometric Indices in Newborns of Pre-Eclamptic and Normal Mothers in Jos, Nigeria

BACKGROUND AND OBJECTIVES

Preeclampsia is a significant public health problem associated with increased risk of hypertension for offsprings. We compared the blood pressure and presence of hypertension between neonates born to women with preeclampsia and those with normal pregnancy as well as its relationship to anthropometric indices.

METHODS

This is a comparative cross-sectional study of 40 neonates born to women with preeclampsia and those born following normal pregnancy in four tertiary health facilities located in Jos, Nigeria. Anthropometric and blood pressure values were measured within 6-12 hours of delivery using standard protocols. SPSS version 25 was used in all analyses. Statistical significance was taken at p <0.05.

RESULTS

The mean birth weight for neonates of preeclamptic women was 2,476.1±810.8 grams, compared with 2,994.2±529.6 grams in babies of normal pregnancy (p=0.002). The mean birth length for neonates of preeclamptic women was 45.4±6.2 cm compared with 49.8±3.1 cm in babies of normal pregnancy (p<0.001). The mean ponderal index (PI) in neonates of preeclamptic women was 2.6±0.6 g/cm3 compared with 2.4±0.4 g/cm3 in babies of normal pregnancy (p=0.17). The mean systolic blood pressure in neonates of women with preeclampsia was 74.53±16.99 mmHg compared with 75.26±15.20 mmHg in neonates following normal pregnancy (p=0.85). The mean diastolic blood pressure in neonates born following preeclampsia was 47.52±15.76 mmHg compared with 45.12±16.9 mmHg in those following normal pregnancy (p=0.46). Six (16%) of the neonates born to women with preeclampsia had systolic hypertension compared with 3(8%) of neonates of women with normal pregnancy. Similarly, 5(14%) of neonates born to women with preeclampsia had diastolic hypertension compared with 2(5%) of neonates of women with normal pregnancy. No significant association between neonatal hypertension and anthropometric indices.

CONCLUSION

Newborns of women with preeclampsia have associated higher odds of elevated blood pressure. Elevated blood pressure has no significant relationship to birthweight, length or ponderal index. Early infant blood pressure surveillance is advocated in order to monitor and hence prevent complications ensuing in later life.

Sociodemographic profiles and use-dynamics of Jadelle (levonorgestrel) implants in Jos, Nigeria

Background:

Contraceptive implants (including Jadelle) are highly effective, safe, and easy to use and have a long duration of action. They do not interfere with intercourse with immediate return to fertility after removal. However, disruption of the menstrual bleeding pattern is almost inevitable and coercive prescription may be a problem because insertion and removal of implants are provider dependent. The objective of this study was to determine the sociodemographic profiles of acceptors of Jadelle and the reasons for discontinuation in Jos, Nigeria.

Materials and Methods:

This was a 6-year retrospective chart review carried out at the Jos University Teaching Hospital.

Results:

About 1401 women accepted Jadelle with a mean (±standard deviation) of 33.4 ± 5.9 years. About 88% of the women were Christians and almost three-quarters (73.5%) had at least secondary school education. The means of parity and number of children still alive at the time of accepting Jadelle were 4.1 and 3.8, respectively. Half of the women (49.5%) were breastfeeding and over half (55.9%) had future fertility desires at the time of commencing Jadelle. About 82% had previously used other contraceptives (mostly short-acting methods such as injectables, pills, and condoms), with only 18% starting Jadelle as the first-ever contraceptive method. About 90% of the women had regular menstrual cycles. The major reason for discontinuation of Jadelle was desire for pregnancy although menstrual pattern disruption was the most common reason for removal in the first 6 months of use.

Conclusion:

The main reason for discontinuation of Jadelle was to have more children although menstrual pattern disruptions accounted for earlier discontinuation.

BODY WEIGHT CHANGES IN WOMEN USING IMPLANON IN JOS, NIGERIA

BACKGROUND

The fear of weight gain is one of the adverse events that make women to discontinue Implanon® (etonorgestrel) contraceptive. Black women are more prone to gain weight with the use of such progestogen-only contraceptives than women of other racial groups. The weight of women is also an important consideration since it influences the concentration of the active drug and may predispose to failure at a higher weight profile.Information on weight changes with the use of etonorgestrel implant is scarce in our sub-region. We therefore explored the direction and extent of weight changes among women in different weight categories and determined the predictors of the final body weight during use of Implanon®.

MATERIALS AND METHOD

This was a retrospective study of all women that accepted implanon at the Family Planning Unit of the Jos University Teaching Hospital, Jos Nigeria from March 2007 to March 2014. Data analysis was carried out using Stata version 12.1. The socio-demographic data and reproductive histories were extracted from the records and the duration of use of the implant, reasons for discontinuation and the initial weight and at follow up were analysed.

RESULTS

Over 99% of the women who had Implanon® were parous and the commonest contraceptive they had used previously was the injectables. However, almost a quarter (22.8%) were accepting Implanon® as their first ever contraceptive method. The mean baseline weight was 64.4 ± 12.1 kg and the median weight was 63.0 kg. The average months of use of Implanon® in this study was 27 months and there was a mean increase in body weight of 2.5 kg during the study. However, there was a broad variability in the individual change in body weight with about 38.6% losing weight or not having any net weight change. Over three-fifths (61.4%) of the women had a net weight gain while using Implanon®. Of these women, 36.0% gained 1-5 kg, 19.2% gained 6-10 kg, 4.2% gained 11-15 kg and 2.0% gained more than 16 kg with the maximum gain at 26 kg. The mean weight changes were 0.8 kg, 1.6 kg, 3.2 kg and 3.3 kg respectively for the first, second, third and fourth years of Implanon® use respectively. Implanon® was removed on account of weight gain in 3.8% of those women who had removed the implant. There was no statistically significant difference in weight gain among the different weight categories: women who had an initial weight above 90 kg gained less than 1 kg compared to those who had normal weight (for this study <70 kg) at the baseline that gained on average more than 2.0 kg. The most significant predictor of the final body weight with Implanon® use was the initial body weight which predicts it in 83.5% of the time (p-value 0.000, CI 0.99, 1.05).

CONCLUSION

There was a broad variability in weight changes with the use of Implanon® and the initial body weight is the most significant predictor of the final body weight. Therefore implanon can be used by women of all weight categories including those considered to be obese.

DECLINING PREVALENCE OF HIV AND OTHER SEXUALLY TRANSMITTED INFECTIONS AMONG FEMALE SEX WORKERS IN JOS, NORTH-CENTRAL NIGERIA

BACKGROUND

Female Sex Workers (FSWs) are key reservoirs of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) from which transmission to the general population fuels epidemics. STIs amplify HIV infectiousness and susceptibility. We determined the status of HIV and STIs among brothel-based FSWs in Jos as part of an ongoing prevention intervention.

METHOD

Between January and May 2012, consenting consecutive brothel-based FSWs were recruited from previously designated brothels across Jos. HIV counseling and testing as well as screening for gonorrhoea, syphilis, trichomonasis, candidasis and Bacteria vaginosis (BV) were performed. Positive cases were provided free treatment and follow-up at Solat Women Hospital, Jos. Ethical clearance was obtained from Jos University Teaching Hospital (JUTH) ethical committee.

RESULT

Two hundred FSWs aged 27.6 ± 4.6 years (range 15-55 years) were recruited and of these, 47 (23.5%) were HIV Positive, 20 (10.0%) had syphilis, 9 (4.5%) had Neisseria gonorrhea, 3 (1.5%) had Trichomonas vaginalis and 86 (43.0%) had BV. The association between HIV and bacterial vaginosis was statistically significant (OR of 2.2, 95% CI of 1.1-4.2, P-value=0.02). In comparison to similar prevalence in 2006, the current findings represent 51.5% decline in HIV prevalence, 40.8% decline for syphilis and over 83.3% decline in prevalence for Trichomonas vaginalis. There was no significant change in the prevalence of Neisseria gonorrhoea and BV.

CONCLUSION

The prevalence of HIV and STIs among brothel-based FSWs in Jos remain unacceptably high, although, there is a declining trend. A comprehensive HIV prevention program targeting these women is required to block transmission to the general population.

Overview of contraceptive use in Jos University Teaching Hospital, north central Nigeria

BACKGROUND

Modern contraceptive methods accepted by 17,846 new clients in Jos University Teaching Hospital, a tertiary health institution, over two decades are presented.

METHODS

This was a review of the contraceptive trend in new clients who used the various methods of contraception over an 18-year period, 1985-2002.

RESULTS

The accepted methods were the intrauterine device (26.1%), oral contraceptive pills (23.5%), female sterilization (21.7%), the Injectable (14.2%), male condom (9.5%), Norplant implants (4.9%) and vasectomy (0.1%). Reversible methods were used by 78.2% and the permanent forms by 21.8%. The women were the acceptors of the methods in 90.5%, while men contributed only 9.5% of the new acceptors. Ten men only had vasectomy over the period of study.

CONCLUSION

The Intrauterine device was the leading method of contraception accepted by the women and male vasectomy was the least accepted by men. There is the need for increased male involvement in contraceptive issues.

Obstetric outcome of twin pregnancies in Jos, Nigeria

OBJECTIVES

The objectives of the study were to determine the incidence, maternal and foetal outcome of twin delivery in Jos, Nigeria.

METHODOLOGY

All consecutive twin deliveries between August 2003 and November 2004 were studied. Data obtained at the time of delivery included maternal age, parity, gestational age at the time of delivery, foetal Apgar scores at birth, gender/sex and foetal weights.

RESULTS

A total of 3,420 deliveries were conducted and 75 were twin deliveries constituting 2.3%, or 1 in 43 deliveries. The mean age and parity of mothers were 28.96 and 3.20 respectively. Male infants constituted 54.7% of the twins with a sex ratio of 1.206 boys to 1.0 girls. Among the twin deliveries, presentation of cephalic-cephalic for the first and second twins was the most common, (48.0%). Male-male twin pair occurred in 33.3%, male-female twins in 22.7%, female-female in 24%, while female-male twins occurred in 20.0%. Males were first twin in 56.0% and second twin in 53.4%; while females were first twin in 44.0% and second twin in 46.6% of the cases. Caesarean section rate was 41.3% in the overall twin pregnancies. Perinatal mortality was 91 per 1000 deliveries.

CONCLUSION

The incidence of twin pregnancy in Jos is high. The commonest maternal morbidity was preterm labour and delivery. Foetal low birth weight was present in about three quarters of the infants. Perinatal mortality rate was expectedly increased in the study. Close antenatal and perinatal assessment and care need be given to mothers of twin pregnancies in order to reduce the maternal and foetal complications.
