- Objective: We evaluated whether regular mobile phone text reminders improved patients' retention in antiretroviral therapy (ART) care in Mozambique.Design: SMSaude was a randomized control trial of HIV-infected patients on ART who received regular text message reminder vs. standard of care at 3 public health facilities in Maputo Province, Mozambique. The primary outcome was retention in HIV care. Between November 2011 and March 2012, 830 eligible HIV-infected patients on ART were randomized 1: 1 to the text reminder intervention or standard of care.Methods: We used Kaplan-Meier estimators and log-rank tests to compare proportions of patients who received SMS reminders who were retained in HIV care compared to the control group who received standard of care. Post hoc analyses were performed using Cox proportional hazards models stratified by urban/rural facility and when initiated ART (<= 3 months vs. >3 months). Hazard ratios and confidence intervals (CIs) are reported. Analysis was with intention to treat.Results: Patients who received text messages had lower attrition from HIV care at 12 months, though the difference was nonsignificant (RR: 0.68, 95% CI: 0.41 to 1.13). Among urban patients, text messages improved retention in HIV care (RR: 0.54, 95% CI: 0.31 to 0.95). Intervention patients newly initiated on ART (<3 months) had lower attrition than control patients (HR: 0.54; 95% CI: 0.23 to 0.91), especially urban newly initiated patients (HR: 0.20, 95% CI: 0.06 to 0.64). Text messages had no effect on retention among rural patients.Conclusions: Text messages did not improve retention in HIV care for all patients on ART but improved retention in care of urban patients and those who recently started ART and received text reminders compared with standard of care.

Journal article (peer-reviewed)abstract
- Migration has been hypothesised to be selective on health but this healthy migrant hypothesis has generally been tested at destinations, and for only one type of flow, from deprived to better-off areas. The circulatory nature of migration is rarely accounted for. This study examines the relationship between different types of internal migration and adult mortality in Health and Demographic Surveillance System (HDSS) populations in West, East, and Southern Africa, and asks how the processes of selection, adaptation and propagation explain the migration-mortality relationship experienced in these contexts. The paper uses longitudinal data representing approximately 900 000 adults living in nine sub-Saharan African HDSS sites of the INDEPTH Network. Event History Analysis techniques are employed to examine the relationship between all-cause mortality and migration status, over periods ranging from 3 to 14 years for a total of nearly 4.5 million person-years. The study confirms the importance of migration in explaining variation in mortality, and the diversity of the migration-mortality relationship over a range of rural and urban local areas in the three African regions. The results confirm that the pattern of migration-mortality relationship is not exclusively explained by selection but also by propagation and adaptation. Consequences for public health policy are drawn.

Human capital on the move : Education as a determinant of internal migration in selected INDEPTH surveillance populations in Africa
- 2016

In: Demographic Research. - 1435-9871. ; 34:on Internal Migration and Urbanization in Developing Countries, JAN 22-24, 1996,, s. 845-884

Journal article (peer-reviewed)abstract
- BACKGROUND Education, as a key indicator of human capital, is considered one of the major determinants of internal migration, with previous studies suggesting that human capital accumulates in urban areas at the expense of rural areas. However, there is fragmentary evidence concerning the educational correlates of internal migration in sub-Saharan Africa. OBJECTIVES The study questions whether more precise measures of migration in Health and Demographic Surveillance System (HDSS) populations support the hypothesis that migrants are self-selected on human capital and more educated people are more likely to leave rural areas or enter urban areas within a geographical region. METHODS Using unique longitudinal data representing approximately 900,000 people living in eight sub-Saharan African HDSS sites that are members of the INDEPTH Network, the paper uses Event History Analysis techniques to examine the relationship between formal educational attainment and in-and out-migration, over the period 2009 to 2011. RESULTS Between 7% and 27% of these local populations are moving in or out of the HDSS area over this period. Education is positively associated with both in-and out-migration in the Kenyan HDSS areas; however, the education effect has no clear pattern in the HDSS sites in Burkina Faso, Mozambique, and South Africa. CONCLUSIONS Empirical results presented in this paper confirm a strong age profile of migration consistent with human capital expectation, yet the results point to variability in the association of education and the propensity to migrate. In particular, the hypothesis of a shift of human capital from rural to urban areas is not universally valid.

Mothers' satisfaction with care during facility-based childbirth : a cross-sectional survey in southern Mozambique
- 2019
-
In: BMC Pregnancy and Childbirth. - : BMC. - 1471-2393 .- 1471-2393. ; 19:1
-
Journal article (peer-reviewed)abstract
- Background Client satisfaction is an essential component of quality of care. Health system factors, processes of care as well as mothers' characteristics influence the extent to which care meets the expectations of mothers and families. In our study, we specifically aimed to address the mothers' experiences of, and satisfaction with, care during childbirth. Methods A population-based cross-sectional study, using structured interviews with published sequences of questions assessing satisfaction, including 4358 mothers who gave birth during the 12 months before June 2016 to estimate satisfaction with childbirth care. Regression analysis was used to determine the predictors of client satisfaction. Results Most mothers (92.5%) reported being satisfied with care during childbirth and would recommend that a family member to deliver at the same facility. Specifically, 94.7% were satisfied with the cleanliness of the facility, 92.0% reported being satisfied with the interaction with the healthcare providers, but only 49.8% felt satisfied with the assistance to feed their baby. Mothers who had negative experiences during the process of care, such as being abandoned when needing help, disrespect, humiliation, or physical abuse, reported low levels of satisfaction when compared to those who had not had such experiences (68.5% vs 93.5%). Additionally, they reported higher levels of dissatisfaction (20.1% vs 2.1%). Regression analysis revealed that mothers who gave birth in primary level facilities tended to be more satisfied than those who gave birth in hospitals, and having a companion increased, on average, the overall satisfaction score, with 0.06 in type II health centres (CI 0.03-0.10) and with 0.05 in type I health centres (CI - 0.02 - 0.13), compared to - 0.01(CI -0.08 - 0.07) in the hospitals, irrespective of age, education and socio-economic background. Conclusion Childbirth at the primary level facilities contributes to the level of satisfaction. The provision of childbirth care should consider women's preferences and needs, including having a companion of choice. We highlight the challenge in balancing safety of care versus satisfaction with care and in developing policies on the optimum configuration of childbirth care. Interventions to improve the interaction with providers and the provision of respectful care are recommended.

Causes of death among women aged 17-49 years between 2007 and 2010 in Maputo, Mozambique.
- 2017

In: Journal of global health. - : International Global Health Society. - 2047-2986 .- 2047-2978. ; 7:2
-
Journal article (peer-reviewed)abstract
- To describe causes of death among young women and estimate the role of HIV/AIDS as a cause in Maputo City, based on the civil death register.Death data of 17-49 year-old women were abstracted from January 2007-March 2010 from the civil death register in Maputo City, registering overall about 15000 deaths per-year. Causes of death in the register were either based on physicians' diagnoses on death certificates or determined by asking questions to deceased relatives. Causes of death were written in Portuguese; we translated them into English and classified them into 106 codes using ICD-9; these codes were then categorized into 10 groups. Estimated populations from the 2007 census were used to calculate annual mortality rates. An earlier study was used to compare deaths in 2001.A total of 9640 deaths (6510 for residents of Maputo City) were registered and 77% had a specified cause of death reported. HIV-deaths represented 36% of all deaths and 40% among 25-39 year-olds. The death rate did not increase linearly by age, as there was a peak among women aged 30-34 years. The overall annual death rate was 6.7 deaths per 1000 population, with a notable decline by year. Death rates for HIV slightly declined by year. HIV-deaths explained most of the peak in death rate among 30-34-year-olds. The share of HIV-deaths among all deaths increased from 18% in 2001 to 35% in 2007-2010. Sixty-eight percent of all and 92% of HIV-related deaths occurred in hospital, with no increase over time.Routine death register was useful to study death rates, distribution of deaths, and change over time in the urban setting of Maputo during late 2000s. Over time, the death rate among 17-49 years old women seemed to have declined, but the relative contribution of HIV increased.

Pregnancy outcomes after first-trimester treatment with artemisinin derivatives versus non-artemisinin antimalarials: a systematic review and individual patient data meta-analysis
- 2023
-
In: The Lancet. - 0140-6736 .- 1474-547X. ; 401:10371, s. 118-130

Journal article (peer-reviewed)abstract
- Background: Malaria in the first trimester of pregnancy is associated with adverse pregnancy outcomes. Artemisinin-based combination therapies (ACTs) are a highly effective, first-line treatment for uncomplicated Plasmodium falciparum malaria, except in the first trimester of pregnancy, when quinine with clindamycin is recommended due to concerns about the potential embryotoxicity of artemisinins. We compared adverse pregnancy outcomes after artemisinin-based treatment (ABT) versus non-ABTs in the first trimester of pregnancy. Methods: For this systematic review and individual patient data (IPD) meta-analysis, we searched MEDLINE, Embase, and the Malaria in Pregnancy Library for prospective cohort studies published between Nov 1, 2015, and Dec 21, 2021, containing data on outcomes of pregnancies exposed to ABT and non-ABT in the first trimester. The results of this search were added to those of a previous systematic review that included publications published up until November, 2015. We included pregnancies enrolled before the pregnancy outcome was known. We excluded pregnancies with missing estimated gestational age or exposure information, multiple gestation pregnancies, and if the fetus was confirmed to be unviable before antimalarial treatment. The primary endpoint was adverse pregnancy outcome, defined as a composite of either miscarriage, stillbirth, or major congenital anomalies. A one-stage IPD meta-analysis was done by use of shared-frailty Cox models. This study is registered with PROSPERO, number CRD42015032371. Findings: We identified seven eligible studies that included 12 cohorts. All 12 cohorts contributed IPD, including 34 178 pregnancies, 737 with confirmed first-trimester exposure to ABTs and 1076 with confirmed first-trimester exposure to non-ABTs. Adverse pregnancy outcomes occurred in 42 (5·7%) of 736 ABT-exposed pregnancies compared with 96 (8·9%) of 1074 non-ABT-exposed pregnancies in the first trimester (adjusted hazard ratio [aHR] 0·71, 95% CI 0·49–1·03). Similar results were seen for the individual components of miscarriage (aHR=0·74, 0·47–1·17), stillbirth (aHR=0·71, 0·32–1·57), and major congenital anomalies (aHR=0·60, 0·13–2·87). The risk of adverse pregnancy outcomes was lower with artemether–lumefantrine than with oral quinine in the first trimester of pregnancy (25 [4·8%] of 524 vs 84 [9·2%] of 915; aHR 0·58, 0·36–0·92). Interpretation: We found no evidence of embryotoxicity or teratogenicity based on the risk of miscarriage, stillbirth, or major congenital anomalies associated with ABT during the first trimester of pregnancy. Given that treatment with artemether–lumefantrine was associated with fewer adverse pregnancy outcomes than quinine, and because of the known superior tolerability and antimalarial effectiveness of ACTs, artemether–lumefantrine should be considered the preferred treatment for uncomplicated P falciparum malaria in the first trimester. If artemether–lumefantrine is unavailable, other ACTs (except artesunate–sulfadoxine–pyrimethamine) should be preferred to quinine. Continued active pharmacovigilance is warranted.

Journal article (peer-reviewed)abstract
- OBJECTIVES: Human papillomavirus (HPV) is a well-known cause of cervical cancer, the second most frequent cancer in female African populations. This study aimed at determining the prevalence of HPV infections and the genotype distribution in young adults aged 18-24, in Maputo city, Mozambique, and to assess the suitability of commercially available HPV vaccines.METHODS: This cross-sectional study was conducted between 2009 and 2011 at a youth clinic in Maputo Central Hospital. Cervical and urethral samples were obtained from 236 women and 176 men, respectively. Demographic and behavioural data were collected using structured questionnaires. HPV genotyping was performed for 35 different high, probably or possibly high-risk and low-risk HPV types using the CLART Human Papillomavirus 2.RESULTS: HPV prevalence was 168/412 (40.8%; 95% CI 36.0 to 45.5) and was significantly higher in women than in men (63.6%vs10.2%). HPV52 was the most frequent type found in women, followed by HPV35, -16,-53, -58,-6 and -51. In men, HPV51 ranked the highest, followed by HPV6, -11,-52, -59 and -70. HIV infection and sexual debut before 18 years of age were associated with multiple HPV infections (OR 3.03; 95% CI 1.49 to 6.25 and OR 6.03; 95% CI 1.73 to 21.02, respectively). Women had a significantly higher HPV infection prevalence than men (p<0.001). The 9-valent HPV vaccine would cover 36.8% of the high-risk genotypes circulating in women in this study, compared with 26.3% and 15.8% coverage by the bivalent and quadrivalent vaccines, respectively.CONCLUSION: This study confirmed the high burden of HPV infections in young women in Maputo city, Mozambique. The HPV prevalence was associated with high-risk sexual behaviour. Sex education and sexually transmitted infection prevention interventions should be intensified in Mozambique. Only a proportion of the high-risk HPV genotypes (37%) were covered by currently available vaccines.

Incidence of HIV and the Prevalence of HIV, Hepatitis B and Syphilis among Youths in Maputo, Mozambique : A Cohort Study
- 2015
-
In: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 10:3
-
Journal article (peer-reviewed)abstract
- Background: Prevalence of HIV in Mozambique among individuals aged 15-49 years is 11.5%. The HIV prevalence is higher in women than in men across the country, peaking at ages 25-29 years and 35-39 years, respectively. In this study, we aimed at determining the prevalence and incidence of HIV, prevalence of Hepatitis B (HBV), and prevalence of syphilis in youths. We also characterized a cohort of youths for future participation in phase I/II HIV vaccine trials.Methods: The study was conducted at a youth clinic in Maputo Central Hospital from August 2009 to October 2011. Youths of both genders aged 18-24 years (n = 1380) were screened for HIV using a sequential algorithm of two immunochromatographic assays, HBV using an enzyme linked immunosorbant test, and syphilis using a treponemal immunochromatographic strip test. The HIV seronegative participants (n = 1309) were followed-up for 12 months with quarterly study visits. The clinical and behavioral data were collected using structured questionnaires. The HIV seroconversions were confirmed by a molecular assay.Results: The study population was female dominant (76.8%). All participants had a formal education, with 44.6% studying for technical or higher education degrees. The mean age at sexual debut was 16.6 years (SD: +/-1.74), with 85.6% reporting more than one sexual partner in life. The screening showed the prevalence of HIV, HBV, and syphilis at 5.1% (95% CI: 3.97-6.31), 12.2% (95% CI 10.5%-14.0%), and 0.36% (95% CI 0.15%-0.84%), respectively. The HIV incidence rate was found to be 1.14/100 person years (95% CI: 0.67-1.92). Retention rates were stable throughout the study being 85.1% at the last visit.Conclusion: Incidence of HIV in this cohort of youths in Maputo was relatively low. Also, the prevalence of HIV and syphilis was lower than the national values in this age group. However, the HBV prevalence was higher than in previous reports in the country.

Journal article (peer-reviewed)abstract
- We assessed safety and immunogenicity of HIV-DNA priming using ZetajetTM, a needle-free device intradermally followed by intramuscular HIV-MVA boosts, in 24 healthy Mozambicans. Volunteers were randomized to receive three immunizations of 600 µg (n = 10; 2 x 0.1mL) or 1200 µg (n = 10; 2 x 0.2mL) of HIV-DNA (3 mg/mL), followed by two boosts of 108pfu HIV-MVA. Four subjects received placebo saline injections. Vaccines and injections were safe and well tolerated with no difference between the two priming groups. After three HIV-DNA immunizations, IFN-γ ELISpot responses to Gag were detected in 9/17 (53%) vaccinees, while none responded to Env. After the first HIV-MVA, the overall response rate to Gag and/or Env increased to 14/15 (93%); 14/15 (93%) to Gag and 13/15 (87%) to Env. There were no significant differences between the immunization groups in frequency of response to Gag and Env or magnitude of Gag responses. Env responses were significantly higher in the higher-dose group (median 420 vs 157.5 SFC/million PBMC, p=0.014). HIV-specific antibodies to subtype C gp140 and subtype B gp160 were elicited in all vaccinees after the second HIV-MVA, without differences in titers between the groups. Neutralizing antibody responses were not detected. Two (13%) of 16 vaccinees, one in each of the priming groups, exhibited antibodies mediating antibody-dependent cellular cytotoxicity to CRF01_AE. In conclusion, HIV-DNA vaccine delivered intradermally in volumes of 0.1-0.2 mL using ZetajetTM was safe and well tolerated. Priming with the 1200 µg dose of HIV-DNA generated higher magnitudes of ELISpot responses to Env.
