Nonconsensual sexual relationship and prevalence of HIV infection in adolescent in Jos, Nigeria.

Background: HIV infection in adolescents is promoted by sexual risky behaviours and nonconsensual sex. Nonconsensual sex ranges from forced sex/rape, unwanted touch and inducement by gifts. This study was designed to determine the prevalence of nonconsensual sex (NCS) and HIV infection in adolescents. Materials and Methods: Eight hundred and eighty three adolescents from 10 secondary schools were randomly selected and given a questionnaire to fill. All had group pre-test counseling had HIV screening. HIV positive subjects had a confirmatory test done after individual post-test counseling. Ethical clearance was received from the relevant authorities and persons. Results: Of the 883 students, 169 (19.2%) were sexually experienced. Of which 101/169 (59.8%) were males and 40.2% females. Mean age at first sexual debut was 14.4±2.6 years; males 13.3±2.7 years and females 14.6±3.2 years, P=0.006. Seventy three of 127 respondents (57.5%) indicated consensual sex and 42.5% (54/127) indicated NCS. Of the 54 subjects, 74% were females and 22% males. Mean age at first sex in NCS was 13.5 + 3.4 yrs; males, 12.5±2.9 yr in NCS and 14±2.6 in consensual, P=0.045; females 14±3.5 in NCS and 16.5±1.2 in consensual P=0.02. Circumstances of sex showed 59.3% were forced sex or rape, 7.4% was following gifts. Over 70% of NCS group use no form of protection. In the population studied 9/883 (1.02%) were HIV positive. Among the sexually experienced HIV prevalence was 2.4% (4/169), and 3.7% (2/54) among NCS. Conclusion: Prevalence of NCS is high, occurring at an earlier age and associated with lack of condom use as well as a higher HIV prevalence.

Is Human Immunodeficiency Virus Still Transmissible Through Blood Transfusion in Children with Sickle Cell Anaemia in Jos, Nigeria?

Aims: To compare the prevalence of HIV infection amongst transfused and non-transfused children with sickle cell anaemia (SCA) in Jos, Nigeria and explore the factors affecting it. Study Design: This was a prospective case control study. Place and Duration of Study: Department of Paediatrics (Sickle Cell Clinic), Jos University Teaching Hospital, Jos, Nigeria, between January 2008 and March 2009. Methodology: A total of 200 transfused children with SCA (117 males and 83 females) were recruited consecutively and screened for HIV using rapid test kits. A questionnaire was used to ascertain the details of blood transfusion and other relevant clinical information. Two hundred age and sex matched non-transfused children with SCA attending the same clinic were recruited as controls. Results: The prevalence of HIV infection amongst transfused children with SCA was 2%, compared to 0% in the control group (P=.04). The four HIV positive cases were transfused in private hospitals with blood of unknown screening status. The number of blood transfusions was Original Research Article British Journal of Medicine & Medical Research, 4(21): 3912-3923, 2014 3913 not a significant factor in acquiring HIV infection (P=.78); however remunerative blood donation increased the risk of acquiring HIV through blood transfusion (AOR=6.28; 95% CI (1.82-9.92); P=.01). Conclusion: HIV is still transmissible through blood transfusion and screening of blood before transfusion is still not completely practiced in Jos, Nigeria. Policies on proper screening of blood before transfusion and voluntary blood donation should therefore be enforced at all levels of healthcare.

Does mid upper arm circumference identify all acute malnourished 6–59 month old children, in field and clinical settings in Nigeria?

Objectives: To determine the utility of mid-upper arm circumference (MUAC) in identifying acutely malnourished children compared with weight-for-height (WHZ), body mass index (BMI) for age (BAZ) and MUAC z-score (MUACZ) in clinical and field practice. Design: Cross-sectional study. Setting: Children from immunisation and paediatric outpatient clinics of Jos University Teaching Hospital and two schools in Jos, Plateau state, Nigeria. Subjects: Children 6–59 months with parental consent, and no chronic medical condition or pedal oedema. Outcome measures: MUAC, height and weight were measured. The WHZ, BAZ and MUACZ were determined using the World Health Organisation (WHO) Anthro software 3.0. Prevalence of acute malnutrition was compared between these data and those given by MUAC. The World Health Organisation (WHO) z-score cut-off of < -3 and < -2 and MUAC of ≤ 11.5 cm and 11.6 –12.5 cm was used to define severe acute malnutrition (SAM) and moderate acute malnutrition (MAM), respectively. Stata 12SE was used to determine frequency distribution, means and significance. Results: The mean age of subjects was 22.4 ± 15.5 months. The mean MUAC was 14.7 ± 1.5 cm. The MUAC differed between males and females in the age-groups of 6–11 (p = 0.02) and 36–47 (p = 0.006) months. The prevalence of SAM by WHZ was 3.4%, MUAC was 1.5%, BAZ was 4.3% and MUACZ was 1.0%. When compared, WHZ and BAZ were concordant in 77.8% (p = 0.001) of SAM subjects. MUAC and MUACZ indicated that none of the subjects were classified as SAM by WHZ and BAZ. Conclusion: Neither WHZ or MUAC as a single parameter identifies all children with acute malnutrition. A re-definition of MUAC criteria for malnutrition or consistent application of both parameters is required.

Survival and nutritional status of children with severe acute malnutrition, six months post-discharge from outpatient treatment in Jigawa state, Nigeria

Background The Outpatient Therapeutic Program (OTP) for treatment brings the management of Severe Acute Malnutrition (SAM) closer to the community. Many lives have been saved through this approach, but little data exists on the outcome of the children after discharge from such programmes. This study was aimed to determine the survival and nutritional status of children at six months after discharge from OTP for SAM. Methodology This was a prospective study of children with SAM admitted into 10 OTPs in two local government areas of Jigawa state from June 2016 to July 2016. Home visits at six months after discharge enabled the collection of data on survival and nutritional status. The primary outcome measures were survival and nutritional status (Mid upper arm circumference and weight-for-height z-score). Result Of 494 children with SAM, 410 were discharged and 379 were followed up. Of these, 354, (93.4%) were found alive while 25 (6.6%) died. Among the survivors 333 (94.1%) had MUAC ≥12.5cm and 64 (18.1%) had WHZ<-3. Mortality rates were higher 10 (8.4%) among the 6-11months old. Most deaths 16 (64%) occurred within the first 3months post-discharge. Those who died were significantly more stunted, p = 0.016 and had a smaller head circumference, p = 0.005 on entry to OTP programme. There was improvement from admission to six months follow up in the number of children with complete immunization (27.4% to 35.6%), and a decrease in the number of unimmunized children (34.8% vs 20.6%) at follow-up. Conclusion The study demonstrates good post discharge survival rate and improved nutritional status for SAM patients managed in OTPs. There were, however considerable post discharge mortality, especially in the first three months and lower immunization uptake post discharge. A follow-up programme will improve these indices further.

Cardiovascular disease risk profile in Nigerian school children

Background: Cardiovascular disease (CVD) is a major cause of death among adults worldwide. It is acknowledged that its risk factors have their roots in childhood. The present study evaluated CVD risk factors in primary school children in a Nigerian peri-urban setting. Methodology: This cross-sectional study was carried out in two primary schools in Jos South local government area, Plateau State, Nigeria. The 241 children studied were chosen using a systematic random sampling technique to select the children from each school. Pretested questionnaire was used to elicit the information on family characteristics and individual characteristics while standard anthropometric and laboratory procedures were used in evaluating the CVD risk factors. Results: Overall, 137 (56.8%) were females (M:F = 0.76), 151 (62.7%) were from the middle class, 59 (24.5%) from lower class while 31 (12.9%) were from the upper class. The overall prevalence of at least one cardiovascular risk factor was 54%. Sedentary lifestyle was the most common CVD risk factor in 32.4% of subjects followed by obesity (13.7%), adverse CVD event in family (11.6%), high low-density cholesterol (10.3%), high total cholesterol (TC) (9.1%), and hypertension (9.1% combine, 7.1% diastolic, and 5.8% systolic). Linear regression analysis showed that body mass index (BMI) for age (β = 0.41, P < 0.001), systolic blood pressure (BP) (β = 0.94, P = 0.03), diastolic BP (β =1.26, P = 0.01), and TC (β = 0.07, P = 0.04) significantly rise with age. BMI for age (P = 0.02) was significantly higher in female subjects compared with their male counterparts. Conclusions: From the findings of the present study, interventions related to modifiable risk factors, such as encouragement of physical exercise and sports in schools, healthy and prudent diet, and weight control programs should be undertaken early in life so as to help control the development of and the epidemic of CVD in later life.

Severe maternal insulin resistance in pregnancy: An independent predictor of fetal macrosomia

Objective: Macrosomia is associated with increased maternal and fetal complications in obstetric practice. Gestational diabetes mellitus (GDM), maternal obesity, insulin resistance (IR), and other variables such as maternal age and gestational age at delivery may influence neonatal birth weight. It is not clear if a severe degree of IR in pregnancy is an independent risk factor for macrosomia. We therefore investigated the association between IR and macrosomia independent of GDM and other confounding factors. Materials and Methods: We measured the insulin sensitivity index (Matsuda index) in 118 pregnant women during a 75-g oral glucose tolerance test at 24-32 weeks of gestation. The birth weights of their neonates were measured at delivery. Multiple logistic regression was use to assess the association between IR and macrosomia after controlling for confounders GDM and other confounding factors. Results: Twenty-four women (20.3%) were classified under IR, 20 women (16.9%) and 62 women (52.5%) had GDM and obesity, respectively. Eleven women (9.3%) had macrosomic babies. Although the fasting insulin and 2-h insulin were higher in women with macrosomic babies compared to the normal weight babies, the observed difference was not significant (P > 0.05). The Matsuda index was significantly lower among women with macrosomic babies. Severe IR (odds ratio [OR] [95% confidence interval (CI)] = 9.3 [2.4-35.1]) and GDM (OR [95% CI] = 12.7 [3.3-49.2]) were significantly associated with macrosomia. After adjusting for the confounding variables, IR remained significantly associated with macrosomia (adjusted OR [95% CI] = 10.0 [1.6-64.4]). Conclusion: IR is an independent risk factor for macrosomia, and its assessment during pregnancy should form a basis for categorizing women at risk of macrosomia.

Knowledge and application of APGAR score among residents in a tertiary hospital

Introduction: The APGAR score rapidly assesses the condition of the newborn at birth and is a predictor of neonatal mortality. Despite the fact that this scoring system is limited by inter and intra-observer variation, its knowledge is essential to residents involved in newborn care at delivery. This study was therefore carried out to determine the knowledge and application of the APGAR score by these residents. Materials and Methods: The questionnaire-based survey was conducted at the Jos University Teaching Hospital and administered to all consecutive residents in pediatrics, obstetrics and gynecology (O and G), anesthesia, family medicine and public health. Domains assessed both knowledge and application of the APGAR scoring system. Data analyzed with the Epi Info 3.5.1 and P < 0.05 was considered as statistically significant. Results: Of the 74 completed questionnaires, 21 were filled by Pediatric residents, 27 by O and G residents and 26 by other residents. Residents with 10-15 years of work experience had a significantly higher mean score on their knowledge compared with those with <10 years work experience (P = 0.015). The mean application score was significantly higher among the Pediatric residents compared with the O and G and other residents (P = 0.015). Using linear regression, there was a significant association between the knowledge and application of the APGAR scoring system - coefficient = 0.179, P ≤ 0.001. Conclusion: Adequate knowledge and application of the APGAR scoring system by residents who use it frequently is necessary to avoid its misuse. Training and retraining of these residents on the correct use of the APGAR score during neonatal resuscitation is important to ensure adequate knowledge and its proper application.

Maternal overweight/obesity characteristics and child anthropometric status in Jos, Nigeria

Objective: This study is to determine the pattern of overweight and obesity and its relationship with childhood anthropometric status in Nigeria. Materials and Methods: This cross-sectional study was conducted in Jos, Nigeria. Interviewer administered questionnaire was used in data collection. Maternal and child anthropometric measurements were obtained using standard WHO methods. Child anthropometric Z scores were obtained from WHO Anthroplus while BMI of mothers were also determined. Totally, 262 mother-child pairs were recruited. Results: Mean maternal age and mean child age were 30.8 ± 6.3 yrs (15-47 yrs) and 22.3 ± 18.7 months (3-72 months). Prevalence of maternal underweight, overweight and obesity was 4.2% (11/262), 29.4% (77/262) and 25.9% (68/262), respectively. Child overweight/obesity was 5.4% (14/262), severe under-nutrition 5.7% (15/262). Mean maternal BMI was higher in the older, more educated and higher socioeconomic status (SES). Child mean birth-weight, weight-for-age Z-score and BMI-for-age Z-score (BAZ) were higher among mothers with BMI ≥ 25 kg/m 2 . All large-for-age babies were in mothers with maternal BMI ≥ 25 kg/m 2 . Childhood over-nutrition was more common in maternal BMI of ≥25 kg/m 2 . Overall, BAZ was directly related with maternal BMI, maternal age and birth-weight, although it was inversely related with maternal BM I ≥ 25 kg/m 2 . Conclusion: Higher BMI is seen in educated and higher SES mothers and this impact on childhood anthropometry.

Intestinal parasites and human immunodeficiency virus (HIV) status of children in Jos, Nigeria

Intestinal parasitic infestations (IPI) are not uncommon in immunocompetent individuals. However, human immunodeficiency virus (HIV)-infected individuals with depleted immunity have an abnormally high susceptibility to infections. This study therefore, examines children with intestinal parasites according to HIV status and degree of immunosuppression. Consecutively consenting patients aged 1 to 15 years attending the Paediatric Clinic of acquired immune deficiency syndrome (AIDS) Prevention Initiative, Nigeria, were recruited as cases, while age and sex matched HIV negative controls were recruited from Out Patient Department of Jos University Teaching Hospital. Stool samples were examined for parasites by direct wet mount, formol-ether and modified Ziehl-Neelsen technique. Levels of immunosuppression were assessed amongst HIV-positive subjects. Five hundred and ten children aged 1 to 15 years equally divided between the two cohorts were enrolled for the study. Seventy-nine had IPI, giving a prevalence rate of 15.5%; 44 (8.6%) HIV positive and 35 (6.9%) HIV-negative children. The most prevalent extracellular parasite was Giardia lamblia, however HIV positives had significantly higher rate of G. lamblia infestation. Among the intracellular parasites, the infection rate in HIV-positive subjects (5.9%) was three times that in HIV-negative subjects (2.0%). HIV positive children with advanced and severe immunosuppression had significantly higher intracellular parasites. HIV status did not significantly predict the overall risk of having extracellular intestinal parasites however, it was noted that G. lamblia infection was significantly higher in HIV positive children. HIV positive children had higher risk of having intracellular parasites especially if they have advanced or severe immunosuppression. Therefore, the policy of screening children for intestinal parasites should continue irrespective of their HIV status. Those that are HIV positive children should specifically be screened for intracellular parasites.

Sero-negative Antibody Status in HIV-Infected Children Initiated on Early Anti-Retroviral Therapy in Jos, Nigeria

Aim: To determine the association between the age at initiation of anti-retroviral therapy (ART) and the 18 month antibody status of human immunodeficiency virus (HIV)-infected children in Jos, Nigeria. Study Design: This was a retrospective cohort study. Place and Duration of Study: AIDS Prevention Initiative in Nigeria (APIN)-supported HIV clinic at Jos University Teaching Hospital, Jos, Nigeria between July 2008 and June 2012. Methods: We reviewed the clinical records of all children confirmed to be HIV-infected with 2 positive HIV deoxyribonucleic acid polymerase chain reaction (DNA PCR) results who were initiated on ART before 12 months of age. We studied the association between the age at initiation of ART and their antibody status at 18months of age. We also studied the association between the viral load and the antibody status.
