Background and objectives: One of the main reasons for risky sexual behavior observed in HIV serodiscordant couples despite the knowledge of the partner's status and counselling is childbearing. In Cameroon, there are few reports on HIV serodiscordant couples. This paper describes the influence of HIV on sexual relationships and decision to procreate.

Methods: This cross-sectional study was conducted in five health centers. Self-administered questionnaire was used to collect social and demographic information, while semi-structured in-depth individual and couple interviews were used to explore sexual relationships and decisions about fatherhood/motherhood. Blood samples were collected from the couples and tested for HIV to confirm serodiscordance. The data were analyzed using the GraphPad Prism Version 6 software.

Results: A total of 53/192 (27.6%) HIV serodiscordant couples participated in the study, and 18/74 (24.32%) HIV positive seroconcordant couples and 32/80 HIV negative seroconcordant couples were used as controls. The majority of HIV-positive partners in serodiscordant couples were women (30/53), of whom 25/30 were on antiretroviral therapy. Nearly half of the respondents (23 /53) reported tensions related to serodiscordance, shown by reduced sex frequency. The use of condoms was not systematically observed among seroconcordant and serodiscordant couples with respective proportions of 55.55% and 20.75% (p = 0.0086). Thirty seven out of 53 HIV serodiscordant couples wanted children, among them, seven couples did not have any and expressed their aspiration for parenthood despite fear of infecting one's partner.

Conclusion and global health implications: Sexuality of serodiscordant couples as well as of HIV positive seroconcordant couples was affected by the presence of HIV/AIDS. The desire to procreate may lead couples to adopt risky sexual behaviors. It is important to define specific guidelines for serodiscordant couples in order to improve their sexual life and consequently enable them to procreate with minimal risk of infecting their partner and or to transmit the virus to their baby.

Background: HIV/AIDS is a hallmark of immune suppression. Micronutrient deficiencies in diet and recurrent opportunistic infections play major roles in the lives of people living with HIV. Although benefits of providing adequate diet to HIV positive persons are well documented, the demand for key elements still remain unclear in particular settings, especially in low and middle-income countries.

Methods: This was a cross sectional analysis of baseline data collected from HIV-infected adults initiating antiretroviral therapy, and who were enrolled in a multivitamin supplementation trial. A food frequency questionnaire was used and intake were obtained as a product of quantities consumed. Adequacy was calculated as the proportion of Recommended Dietary Allowances (RDA). A chi square test and logistic regression analysis were used at p-value 0.05 to show significant associations.

Results: Mean intakes were above minimum requirements for analyzed micronutrients with the exception of Calcium and Iron. Participants who met RDA intakes were as follows: highest (≥ 80%) for Magnesium, Selenium, Zinc and Vitamins B2, B6, B9, C and E; moderate (50% to <80%) for Vitamins B3, and A; and lowest (≤50%) for Iron (30%), Calcium (14.9%), Vitamins B12 and B1. Gender differences in met RDA were observed for Iron, Selenium, Zinc, Vitamins A, B1, B3 and E. In multivariable analyses, nutritional status and CD4 count had no influence on meeting RDA for majority of micronutrients such as magnesium, Selenium, B class vitamins (B1, B2, B3, B6, B9, B12), vitamin (A, C, and E), Zinc and Calcium, but not including iron.

Conclusion and global health implications: Diets consumed by the study participants were low in most protective nutrients (Iron, Calcium, Zinc, Vitamin A, B1, B3, and B12). This deficiency was more common among females than males, and irrespective of BMI or CD 4 count. Findings warrant further investigation on the impact and cost implications for suplementation interventions that target the elements lacking in the diets of people living with HIV in similar low-resourced settings.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the causative agent for coronavirus disease 2019 (COVID-19), and its ensuing mitigation measures have negatively affected the Maternal and Child Health (MCH) population. There is currently no surveillance system established to enhance our understanding of SARS-CoV-2 transmission to guide policy decision making to protect the MCH population in this pandemic. Based on reports of community and household spread of this novel infection, we present an approach to a robust family-centered surveillance system for the MCH population. The surveillance system encapsulates data at the individual and community levels to inform stakeholders, policy makers, health officials and the general public about SARS-CoV-2 transmission dynamics within the MCH population.

Background and objectives: The identification of risk factors for shorter telomere length, especially during fetal development, would be important towards caffeine consumption recommendations for pregnant women on a global scale. The purpose of this study was to evaluate the association between caffeine intake and fetal telomere length as well as racial/ethnic differences in telomere length regardless of maternal caffeine consumption status.

Methods: Caffeine intake was measured using a food frequency questionnaire (FFQ). Three generalized linear models (GLM) were compared based on binary categorical variables of caffeine levels using data mean value of 117.3 mg as cut-off; the World Health Organization (WHO) recommendations of 300 mg; and the American College of Obstetricians and Gynecologists (ACOG) recommendations of 200 mg. The association between caffeine consumption and telomere length (telomere to single-copy [T/S] ratio) was then assessed.

Results: Among 57 maternal-fetal dyads, 77.2% reported less than 200 mg of caffeine (ACOG) and 89.5% less than 300 mg (WHO). Both WHO and ACOG models found that caffeine intake was significantly and positively associated with longer telomere length (p<0.05); and sodium (p<0.05). Other" race (p<0.001) and "white" race (p<0.001) were also significantly and positively associated with longer telomere length in the same models. Increasing maternal age shortened telomere length significantly in all models (p<0.001).

Conclusion and global health implications: Caffeine intake, maternal age, and race may be associated with alterations in fetal telomere length. This indicates that caffeine consumption during pregnancy may have long-term implications for fetal development. The racial/ethnic differences in telomere length found in this study warrant larger studies to further confirm these associations.

Background and objectives: India, the second most populous country in the world, has two-thirds of its population living in rural areas. Rural women in developing countries like India have worse access to healthcare compared to their urban counterparts. We examined the association between place of residence and various pregnancy and birth outcomes among Indian women.

Methods: We analyzed data from the 2015-2016 India Demographic and Health Survey (DHS). Socio-demographic and reproductive health-related information were obtained from Indian women of reproductive age. We calculated the prevalence of selected pregnancy and birth outcomes among the study participants. We conducted adjusted survey log binomial regression to determine the level of association between place of residence and various pregnancy and birth outcomes.

Results: About 66.4% of the survey responders resided in villages. When adjusted for covariates, rural women had increased likelihood of experiencing miscarriage, stillbirth, early neonatal, late neonatal and infant mortality as compared to urban women. Urban women had 22% higher likelihood (PR = 1.22, 95% CI=1.10-1.35) of having an abortion as compared to rural dwellers.

Conclusion and global health implications: Despite India's extensive efforts to improve maternal and reproductive health, wide geographical disparities exist between its urban and rural population. Interventions at various socio-ecologic and cultural levels, along with improved health literacy, access to improved health care and sanitation need attention when formulating and implementing policies and programs for equitable progress towards improved maternal and reproductive health.

Background and objectives: Studies on male involvement and pregnancy outcomes have often not incorporated the providers' perspectives, which are potentially critical to understanding program context, evolution, perceived impact, and sustainability. We sought to evaluate the 24/7 Dad® program from the viewpoint of the program providers.

Methods: We conducted purposive sampling of 24/7 Dad program facilitators and administrators who were involved in recruitment, training, and follow up of program participants within a federal Healthy Start program (REACHUP) in Tampa, Florida, USA. Using a snowballing approach, we recruited six key informants who had administered the program for at least four years. We elicited and evaluated factors impacting the performance of the father involvement program using content analysis.

Results: Under program participation and perceived impact, most providers thought that the program had created a safe space previously unavailable for men in the community. The most useful recruitment strategy was building partnerships with other organizations. The key informants noted an important evolutionary trend in the father involvement program over time as well as the nature of linkages to partner organizations within the area. Threats to program sustainability included the continued reluctance and scepticism to invest funds to address male issues, sub-optimal retention of participants who were living transient lives as well as geographical/transportation barriers.

Conclusion and global health implications: The involvement of fathers during pregnancy has significant implications for healthy babies. Our study results provide a clarion call to augment capacity and infuse more resources to improve paternal involvement in order to attain the United Nations Sustainable Goal (2015-2030) of ensuring healthy lives and the promotion of well-being for all at all ages.

Background: The vaginal microbiota is an important component of the reproductive health of women as it offers protection against urogenital infection. African women are reported to have a vaginal microbiota colonized with high proportions of strict anaerobes rather than lactobacillus- dominated microbes. These strict anaerobes have been associated with pre-term birth and neonatal disease. The prevalence of pre-term birth (PTB) in Africa poses a major challenge to reproductive healthcare, hence the clinical and scientific attention focused on understanding the causative mechanisms of PTB. A pragmatic approach to curbing PTB requires the identification of the vaginal microbiome during various stages of a healthy pregnancy (the 'normal'). This information will provide baseline data for future investigations of vaginal microbiome that may cause PTB (the 'abnormal'). We present a protocol for the longitudinal analysis of vaginal microbiome in a cohort of pregnant women in Southwest Nigeria.

Methods: We propose to recruit 51 pregnant Nigerian women, enrolling them into the study at 17-21 gestational weeks. Two vaginal swab samples and three milliliters of blood would be collected at enrollment. Sample collection will be repeated at 27-31 weeks' gestation, ≥36 weeks' gestation, 24-48 hours after birth and 6 weeks post-partum. DNA will be extracted from the vaginal samples and 16S rRNA sequencing would be performed. Blood samples collected would be assayed by ELISA technique for placental steroid hormones. Data will be statistically analyzed and considered in the light of vaginal microbial diversity, clinical, nutrition and other health data.

Conclusion and global health implication: Our data set will bring new insights into the vaginal microbiome of apparently healthy African women in pregnancy and postpartum, which should serve as a baseline for the investigation of vaginal microbes that may provide useful information for the prediction and management of preterm birth. It is anticipated that these data will facilitate future personalized therapeutic management and consequently improve the reproductive health fitness of women in Africa.

Background and objectives: The period of transition from breastfeeding to other foods and liquids, is a very vulnerable period when malnutrition is likely to start in many infants and young children, if appropriate feeding practices are not employed. This study assessed using composite indices, the appropriateness of complementary feeding practices and associated factors among nursing mothers in Ijebu-Ode, Ogun State.

Methods: This descriptive cross sectional study was conducted in selected primary health facilities in Ijebu-Ode. Multi stage sampling technique was employed to select 283 mother-child pairs. Data was collected using a pre-tested interviewer administered questionnaire which included the World Health Organization Infant and Young Child Feeding Indicators (WHO IYCF) and the Infant and Child Feeding Index (ICFI).

Results: Of the total 283 mother-child pairs studied, 33.6% met minimum meal frequency, 14.5% received minimum dietary diversity (≥4 food groups) and 9.2% received minimum acceptable diet when assessed using the WHO IYCF indicators. Overall, appropriate complementary feeding was low (4.2%) and associated (p<0.05) with factors such as antenatal care visits, child welfare clinic attendance and mother's workplace. On the other hand, the ICFI categorized respondents into low (11.7%), medium (24.7%) and high (63.6%) ICFI scores and were associated (p<0.05) with mother's education and household size.

Conclusion and global health implications: This study revealed a high prevalence of inappropriate complementary feeding practices. The use of composite indices reflected these practices and their associated factors holistically as they revealed different dimensions of complementary feeding. This may be useful for monitoring, evaluation, research and the required advocacy for complementary feeding.

African Americans are bearing a disproportionate burden of morbidity and mortality due to COVID-19 pandemic. To our knowledge, no previous study has delineated inequities potentially incentivized by systemic racism, and whether synergistic effects impose an abnormally high burden of social determinants of mental health on African American families in the era of COVID-19 pandemic. We applied the social ecological model (SEM) to portray inequities induced by systemic racism that impact the mental health of African American families. In our model, we identified systemic racism to be the primary operator of mental health disparity, which disproportionately affects African American families at all levels of the SEM. Programs tailored towards reducing the disproportionate detrimental effects of COVID-19 on the mental health of African Americans need to be culturally appropriate and consider the nuances of systemic racism, discrimination, and other institutionalized biases.

Objective: This paper evaluates the association between caffeine consumption during pregnancy and overweight or obesity in the offspring.

Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a literature search was conducted using MedLine, PubMed, CINAHL-Plus and Google Scholar databases. Inclusion criteria were cohort studies on participants with live singleton births at ≥28 weeks gestation who had consumed caffeine during pregnancy. Included were studies reporting both measurement of maternal caffeine intake and offspring anthropometric measurements. Studies reporting serum paraxanthine, a measurement of caffeine intake, were also included.

Results: After final elimination, there were eight studies meeting our inclusion criteria. From these studies, we deduced that caffeine intake during pregnancy between 50 mg and <150 mg/day was associated with increased risk of overweight and obesity by excess fat deposition or increased weight, and elevated BMI per International Obesity Task Force (IOTF) criteria using a reference population. The majority of studies reported the strongest association with maternal caffeine intake during pregnancy and overweight and obesity risk beginning at ≥300 mg/day.

Conclusions and global health implication: The risk of childhood overweight or obesity was associated with caffeine consumption at 50 mg/day during pregnancy with a stronger association at intakes ≥300 mg/day and higher. The current recommendation of <200 mg/day of caffeine during pregnancy is likely associated with lower risk of overweight or obesity in offspring but avoidance of the substance is recommended.
