Nocturnal systolic blood pressure dipping among people living with HIV and people without HIV: a cross-sectional study in Rural Uganda.

Background: In this study, we investigated sleep quality, depression and stress symptoms as hypothesized factors affecting the association between HIV status and nocturnal blood pressure dipping status in rural Uganda. Methods: Individuals living with HIV (PLHIV) and people without HIV (PwoHIV) underwent 24-hour ambulatory blood pressure monitoring (ABPM) and classified as extreme dippers, dippers and non-dippers based on a percentage nocturnal drop in mean systolic and diastolic blood pressure. Ordinal logistic regression models were used to assess the effect of different exposure variables (HIV status, sleep quality and other covariates) on the outcome (dipping status). Results: The median age was 45 years (IQR: 35-54) and 80% of the participants were female. 24% of PwoHIV and 16% of PLHIV were overweight, 10% of HIV negative and 3% of the HIV positive individuals were obese. Depression was prevalent in both PLHIV and PwoHIV. Additionally, poor sleep quality was more prevalent in PLHIV compared to PwoHIV (70% versus 58%, P= 0.046). The study found that 53% of participants had normal dipping, while 35.1% were non-dippers, with non-dipping being more prevalent in PwoHIV individuals (34.9% vs 29.7%, P<0.001). PLHIV had 3.6 times the odds of being extreme dippers compared to PwoHIV (OR 3.64, 95% CI: 1.40 - 9.44). Conclusion: This study identified high proportions of non-dipping BP profiles among both PLHIV and PwoHIV. However, the odds of being extreme dippers were higher among PLHIV compared to PwoHIV. Further research is needed to understand the underlying mechanisms contributing to extreme dipping patterns in PLHIV.

Primary HIV prevention in pregnant and lactating Ugandan women: A randomized trial.

BACKGROUND: The 'Primary HIV Prevention among Pregnant and Lactating Ugandan Women' (PRIMAL) study aimed to assess the effectiveness of an enhanced HIV counseling intervention for preventing HIV acquisition among HIV-uninfected mothers during pregnancy and throughout the breastfeeding period. METHODS: We conducted an unblinded randomized control trial between 22 February 2013 and 22 April 2016 to assess the effectiveness of an extended repeat HIV testing and enhanced counseling (ERHTEC) intervention aimed at preventing primary HIV infection among HIV-uninfected pregnant and lactating women in Uganda. HIV-uninfected pregnant women aged 15-49 were enrolled 1:1 individually or in couples together with their partner. Enrolled women and couples were randomized 1:1 to an intervention (ERHTEC) or control (extended repeat HIV testing and standard counseling) group and followed up to 24 months postpartum or six weeks past complete cessation of breastfeeding, whichever came first. Both groups were tested for sexually transmitted infections (STIs) and HIV at enrollment, delivery, 3 and 6 months postpartum and every 6 months thereafter until the end of follow-up. The intervention group received enhanced HIV prevention counseling every 3 months throughout follow-up. The control group received standard counseling at the time of HIV retesting. Both intervention and control couples were offered couple HIV testing and counseling at all study visits. MAIN OUTCOME MEASURES: Frequency of condom use and incidence of HIV, syphilis, gonorrhea, chlamydia and trichomoniasis over follow-up. RESULTS: Between February 2013 and April 2014, we enrolled 820 HIV-uninfected pregnant women presenting for antenatal care individually (n = 410) or in couples (n = 410 women and 410 partners) in one urban and one rural public Ugandan hospital. Women's median age was 24 years (IQR 20-28 years). At baseline, participants did not differ in any socio-demographic, reproductive health, HIV testing history, sexual behavior, medical history or STI status characteristics; 96% (386/402) of couples were tested and counseled for HIV together with their partners at enrolment, 2.1% (7/329) of whom were found to be HIV-infected. Six hundred twenty-five (76%) women completed follow-up as per protocol (S1 Protocol). Women were followed for an average of 1.76 years and cumulated 1,439 women-years of follow-up or 81% of the maximum 1,779 women-years of follow-up assuming no dropouts. Men were followed for an average of 1.72 years. The frequency of consistent condom use and the proportion of women who used condoms over the last 3 months or at last vaginal sex increased substantially over follow-up in both arms, but there were no statistically significant differences in increases between the intervention and control arms. During follow-up, on average 42% (range 36%-46%) of couple partners were counseled together. Between 3.8% and 7.6% of women tested positive at any follow-up visit for any STI including syphilis, gonorrhea, C. trachomatis or T. vaginalis. Four women (two in each arm) and no enrolled men became infected with HIV, representing an overall HIV incidence rate of 0.186 per 100 person-years. Three of the women seroconverters had enrolled individually, one as a couple. At or before seroconversion, all four women reported their partners had extramarital relationships and/or had not disclosed their suspected HIV-infected status. There were no statistically significant differences between study arms for STI or HIV incidences. CONCLUSIONS: A sustained enhanced HIV prevention counseling intervention for up to 2 years postpartum among pregnant and breastfeeding women did not have a statistically significant effect on condom use or HIV incidence among these women. However, in both study arms, condom use increased over follow-up while STI and HIV incidence remained very low when compared to similar cohorts in and outside Uganda, suggesting that repeat HIV testing during breastfeeding, whether with enhanced or standard counseling, may have had an unintended HIV preventive effect among pregnant and lactating women in this setting. Further research is needed to verify this hypothesis. TRIAL REGISTRATION: ClinicalTrials.gov NCT01882998.

Health related quality of life in children with spina bifida in Uganda.

BACKGROUND: Studies on health related quality of life (HRQOL) of children with disabilities in low income countries are limited. OBJECTIVE: To inform interventions for children with spina bifida in low income countries, HRQOL of children with spina bifida and siblings, predictors, relationships between HRQOL and parental stress in Uganda were examined. METHODS: Demographic, impairment, daily, social functioning data, and HRQOL using the KIDSCREEN-10 were collected from 39 children, 33 siblings, and 39 parents from a cohort of families of children with spina bifida. T-tests, correlations, analysis of variance and regression analysis were used to compare means between children with spina bifida and their siblings, understand relationships between variables, and identify predictors of HRQOL. RESULTS: Children with spina bifida (N = 39) had lower HRQOL compared to their siblings (N = 33) (t = -3.868, p < .001 parental; t = -3.248, p = .002 child ratings). Parents (N = 39) indicated higher parental stress for their child with spina bifida (t = 2.143, p = 0.036). HRQOL child outcomes were predicted by the presence of hydrocephalus (ß = -.295, p = 0.013) for children with spina bifida, and daily functioning levels (ß = .336, p = 0.038), and parental support (ß = .357, p = 0.041) for siblings specifically. Parent rated HRQOL outcomes were predicted by parental distress (ß = -.337, p = 0.008), incontinence (ß = .423, p = 0.002), and daily functioning levels (ß = .325, p = 0.016) for children with spina bifida. CONCLUSIONS: To improve HRQOL investment in neurosurgical care, community based rehabilitation, incontinence management, and parental support are required. A combination of child friendly semi-structured and creative research methods are recommended to study HRQOL.

Parental stress and support of parents of children with spina bifida in Uganda.

BACKGROUND: Children with disabilities in Sub-Saharan Africa depend for a large part of their functioning on their parent or caregiver. This study explores parental stress and support of parents of children with spina bifida in Uganda. OBJECTIVES: The study aimed to explore perceived stress and support of parents of children with spina bifida living in Uganda and the factors that influence them. METHODS: A total of 134 parents were interviewed. Focus group discussions were held with four parent support groups in four different regions within the country. The Vineland Adaptive Behaviour Scales, Daily Functioning Subscales and Parental Stress Index Short Form (PSI/SF) were administered to measure the child's daily functioning level and parental stress levels. RESULTS: Parental stress was high in our study population with over half of the parents having a > 90% percentile score on the PSI/SF. Stress outcomes were related to the ability to walk (Spearman's correlation coefficient [ρ] = -0.245), continence (ρ = -0.182), use of clean intermittent catheterisation (ρ = -0.181) and bowel management (ρ = -0.213), receiving rehabilitative care (ρ = -0.211), household income (ρ = -0.178), geographical region (ρ = -0.203) and having support from another parent in taking care of the child (ρ = -0.234). Linear regression showed parental stress was mostly explained by the child's inability to walk (ß = -0.248), practicing bowel management (ß = -0.468) and having another adult to provide support in caring for the child (ß = -0.228). Parents in northern Uganda had significantly higher scores compared to parents in other regions (Parental Distress, F = 5.467*; Parent-Child Dysfunctional Interaction, F = 8.815**; Difficult Child score, F = 10.489**). CONCLUSION: Parents of children with spina bifida experience high levels of stress. To reduce this stress, rehabilitation services should focus on improving mobility. Advocacy to reduce stigmatisation and peer support networks also need to be strengthened and developed.

Prevention of spina bifida: folic acid intake during pregnancy in Gulu district, northern Uganda.

INTRODUCTION: The intake of folic acid before conception and during the first trimester of pregnancy can prevent spina bifida. This paper describes folic acid intake in women in Gulu district in northern Uganda. METHODS: Structured interviews were held with 394 women attending antenatal care (ANC), 15 mothers of children with spina bifida, and 35 health workers in 2012 and 2013. SPSS16 was used for data analysis. RESULTS: 1/4 mothers of children with spina bifida took folic acid during late pregnancy, none preconception. None had knowledge about folic acid and spina bifida prevention. 33.5% of women attending ANC had ever heard about spina bifida, 1% knew folic acid intake can prevent spina bifida. 42.4% took folic acid supplements in late pregnancy, 8.1% during the first trimester, none preconception. All women said to have eaten food rich in folic acid. None were aware about fortified foods. 7% of health workers understood the importance of early folic acid intake. All health workers recommended folic acid intake to women attending ANC. 20% of the health workers and 25% of the women said folic acid supplements are not always available. CONCLUSION: Folic acid intake is limited in northern Uganda. This is attributed to limited education and understanding of women and health workers about the importance of early folic acid intake, late presentation of women at ANC, poor supply chain and dilapidated health services caused by war and poverty. A combination of food fortification, sensitization of health workers, women, and improving folic acid supply is recommended.
