Healthy pregnancies and essential fats: focus group discussions with Zambian women on dietary need and acceptability of a novel RUSF containing fish oil DHA

BackgroundNut butter-based Ready to Use Supplemental Foods (RUSF) are an effective way to add nutrients and calories to diets of malnourished and food insecure populations. The RUSF formulations have been further modified to add micronutrients including iron and folic acid needed during pregnancy and lactation. Because docosahexaenoic acid (DHA, C22:6 n-3) enhances fetal development and birth outcomes, it has been suggested that perhaps RUSF formulations for pregnancy should also include this Omega 3 fatty acid. The goal of the present study was to gain an understanding of Zambian women’s knowledge of nutritional needs in pregnancy through structured focus group discussions, and to formulate and determine the acceptability of a RUSF with DHA.MethodsStructured focus group sessions were conducted among women attending an antenatal clinic at the University Teaching Hospitals in Lusaka, Zambia. Dietary and nutrition knowledge was surveyed through structured dialogue that was recorded by audio and transcribed verbatim. An RUSF containing 400 mg DHA from fish oil in 50 g RUSF was designed and assessed for fatty acid content and product stability. Participants then sampled the RUSF-DHA, provided feedback on taste, and were surveyed about willingness to consume the novel formula using a standardized hedonic instrument.ResultsThe participants’ knowledge of foods recommended for use in pregnancy included fruits, vegetables, meat, and fish. Most women reported eating fish at least once per week, although the specific type of fish varied. Most did not have prior knowledge of the importance of consuming fish during pregnancy or that some fish types were more nutritional than others as they included omega 3 fatty acids. The participants were uniformly accepting of the RUSF-DHA for the purpose of enhancing birth and developmental outcomes, but were critical of the aroma in hedonic testing.ConclusionsWomen were committed to consuming a healthy diet that would impact the outcome of pregnancy, and were receptive to advice on the importance of consuming foods such as fish as a source of DHA. The RUSF-DHA formulation was acceptable due to the potential benefits for the developing infant, however, the fishy odor may be limiting for long-term daily use.

Vaginal progesterone to prevent preterm delivery among HIV-infected pregnant women in Zambia: A feasibility study.

Antenatal vaginal progesterone (VP) reduces the risk of preterm birth (PTB) in women with shortened cervical length, and we hypothesize that it may also prevent PTB in women with HIV as their primary risk factor. We conducted a pilot feasibility study in Lusaka, Zambia to investigate uptake, adherence, and retention in preparation for a future efficacy trial. This was a double-masked, placebo-controlled, randomized trial of 200mg daily self-administered VP suppository or placebo. Pregnant women with HIV who were initiating or continuing antiretroviral therapy were eligible for participation. Potential participants underwent ultrasound to assess eligibility; we excluded those ≥24 gestational weeks, with non-viable, multiple gestation, or extrauterine pregnancies, with short cervix (<2.0cm), or with prior spontaneous PTB. Participants initiated study product between 20–24 weeks of gestation and continued to 37 weeks (or delivery, if sooner). The primary outcome was adherence (proportion achieving ≥80% study product use), assessed by dye stain assay of returned single-use vaginal applicators. Secondary outcomes with pre-defined feasibility targets were: uptake (≥50% eligible participants enrolled) and retention (≥90% ascertainment of delivery outcomes). We also evaluated preliminary efficacy by comparing the risk of spontaneous PTB <37 weeks between groups. From July 2017 to June 2018, 208 HIV-infected pregnant women were eligible for screening and 140 (uptake = 67%) were randomly allocated to VP (n = 70) or placebo (n = 70). Mean adherence was 94% (SD±9.4); 91% (n = 125/137) achieved overall adherence ≥80%. Delivery outcomes were ascertained from 134 (96%) participants. Spontaneous PTB occurred in 10 participants (15%) receiving placebo and 8 (12%) receiving progesterone (RR 0.82; 95%CI:0.34–1.97). Spontaneous PTB < 34 weeks occurred in 6 (9%) receiving placebo and 4 (6%) receiving progesterone (RR 0.67; 95%CI:0.20–2.67). In contrast to findings from vaginal microbicide studies in HIV-uninfected, non-pregnant women, our trial participants were highly adherent to daily self-administered vaginal progesterone. The study’s a priori criteria for uptake, adherence, and retention were met, indicating that a phase III efficacy trial would be feasible.

Fertility intentions and long-acting reversible contraceptive use among HIV-negative single mothers in Zambia

Integrating family planning interventions with HIV studies in developing countries has been shown to prevent mother-to-child HIV transmission and simultaneously reduce HIV and unintended pregnancy in high-risk populations. As part of a prospective cohort study on HIV incidence and risk factors in Zambian women having unprotected sex, we also offered family planning counseling and immediate access to long-acting reversible contraceptives. Although long-acting reversible contraceptives are the most effective form of contraception, many Zambian women are limited to oral or injectable methods because of a lack of knowledge or method availability. This project offers to single mothers who are enrolled in a cohort study information about and access to long-acting reversible contraceptives at enrollment and at each follow-up visit. This study evaluates how fertility intentions affect long-acting reversible contraceptive use in HIV-negative single mothers in Zambia. Our primary outcome was long-acting reversible contraceptive use throughout the study participation. We also estimated rates of long-acting reversible contraceptive uptake and discontinuation. We specifically studied single mothers because they are at high risk for unintended pregnancy, which can have significant negative ramifications on their financial, social, and psychologic circumstances. From 2012-2017, Zambia Emory HIV Research Project recruited 521 HIV-negative single mothers ages 18-45 years from government clinics in Lusaka and Ndola, Zambia's 2 largest cities. Participants were followed every 3 months for up to 5 years. At each visit, we discussed fertility goals and contraceptive options and offered a long-acting reversible method to any woman who was not pregnant or who already was using a long-acting reversible or permanent contraceptive method. Data were collected on demographic factors, sexual behavior, and reproductive history. Multivariable logistic regression was used to model baseline fertility intentions with long-acting reversible contraceptive use. We enrolled 518 women; 57 women did not return for any follow-up visits. There was a significant increase in long-acting reversible contraceptive use during the study. At baseline, 93 of 518 women (18%) were using a long-acting reversible method, and 151 of 461 women (33%) used a long-acting reversible method at the end of follow-up period (P<.0001). Four women chose an intrauterine device, and 91 women chose an implant for their first uptake event. After we adjusted the data for other confounders, we found that women in Ndola who did not desire any more children were more likely to use a long-acting reversible contraceptive (adjusted prevalence ratio, 2.02; 95% confidence interval, 1.88-3.42). During follow up, 37 of 183 long-acting reversible contraceptive users (20%) discontinued their method; women who desired future children at baseline were more likely to discontinue earlier (P=.016). This study demonstrates that integrated family planning services can increase long-acting reversible contraceptive use successfully among Zambian single mothers, who are a vulnerable population that disproportionately is affected by unintended pregnancy. A steady increase in use over time confirms the importance of repeated messaging about these unfamiliar methods. Thus, it is imperative that family planning interventions target single mothers in developing countries to promote effective contraceptive use.

Information Needs of Breast Cancer Patients at Cancer Diseases Hospital, Lusaka, Zambia

Background: Breast cancer is the second most common cancer worldwide and the second most common among Zambian women. Breast cancer diagnosis being a stressful experience, causes psychological and emotional disruption that can be abated by meeting information needs of the affected patients. In light of the escalating cases of Breast cancer among the Zambian women, the study examined a special aspect of cancer management which is usually neglected in most cases. Aim: The main objective of the study was to assess information needs of breast cancer patients at the Cancer Diseases Hospital in Lusaka, Zambia using a modified structured interview schedule adopted from the Toronto Information Needs Questionnaire-Breast Cancer (TINQ-BC). Methods: A descriptive cross-sectional design was used to elicit the information needs of breast cancer patients. One hundred and ten (97% response rate) participants were selected using simple random sampling method and data was collected using a modified structured interview schedule adopted from the Toronto Information Needs Questionnaire-Breast Cancer (TINQ-BC). Stata 10.0 (StataCorp, 2008) was employed for all quantitative data analysis and graphical presentation of data. Results: The overall score for information needs was obtained by adding the scores across all the five information needs categories which were further divided into three categories namely: low important scores, of less than 50%, moderately important scores of 50% - 70% and highly important scores ranged above 70% of the 200 total scores. Out of the 110 participants recruited, 88 (80%) indicated that the information across the five categories was moderately important. Logistic regression of information needs and posited determinants revealed that anxiety levels; education level; presence of co-morbidity; and being on treatment were significant determinants of patients’ informational needs (Effect’s p ≤ 0.05). Conclusion: The findings of this study support the idea that breast cancer patients are seeking more information on their illness, hence information provision is one of the most important factors for providing high quality cancer care across the whole cancer continuum. Therefore, appreciating the information needs of breast cancer patients is substantial in improving care.

Women's Perceptions of Intimate Partner Violence in Zambia

Despite growing awareness of violence against women, intimate partner violence (IPV) continues to be a major public health issue worldwide. Understanding factors associated with attitudes toward violence against women is a crucial first step in developing prevention strategies to reduce the occurrence of IPV. This secondary data analysis used data from 9353 women who participated in the 2013–2014 Zambia Demographic and Health Survey (ZDHS) to examine demographic and social factors associated with attitudes toward wife beating—a common type of IPV. Our main research objectives were: (1) examine the most common reasons for endorsement (justification) of wife beating by Zambian women and (2) determine the predictors of approval (or justification of) wife beating by Zambian women. In addition, this study investigated the relationship between wealth and media on perceptions of wife beating in Zambia. Descriptive, bivariate, multivariate, and logistic regression analyses were conducted to assess the effects of sociodemographic factors on women's perceptions of wife beating. Over half (53.5%) of Zambian women endorsed at least one justification for wife beating. Wealth index, listening to the radio, reading the newspaper or magazine, and watching television (TV) were significant predictors of women's endorsement of wife beating. We also examined the role of media exposure as a mediator between wealth and endorsement of wife beating. Women who reported reading the newspaper or magazine and watching TV were less likely to support wife beating; however, women who listened to the radio were more likely to support wife beating. Justification and endorsement among Zambian women is problematic and suggests that for some, wife beating is a cultural norm. Interventions aimed at reducing wife beating in Zambia should include broad public awareness and media campaigns on violence against women.

Intimate partner violence polyvictimisation and HIV among coupled women in Zambia: Analysis of a population-based survey

ABSTRACTWomen in sub-Saharan Africa are disproportionately at risk for the dual epidemics of intimate partner violence (IPV) and HIV. Little is known about how specific violence profiles affect women’s HIV risk, limiting effective intervention. We analysed couples’ data from the Zambia Demographic and Health Survey 2013–2014 to evaluate relationships among IPV, male partner HIV status and women’s HIV status. We considered the individual and combined effects of physical, sexual, emotional, and high controlling behaviour violence and accumulated violence exposure, respectively. Among partnered women, 48.9% (n = 2,812) experienced IPV victimisation, of whom 52.1% (n = 1,465) reported polyvictimisation (experiencing two or more violence types). Female HIV prevalence was 13.2%. Adjusted for demographics, HIV was significantly higher for women who experienced three (17.3%, aPR 1.33, 95%CI: 1.04–1.69, p = 0.02) or four (22.1%, aPR 1.66, 95%CI: 1.23–2.26, p ≤ 0.01) types versus no IPV. Violence including emotional and/or high controlling victimisation was associated with female HIV infection (aPR: 1.31, 95%CI: 1.09–1.57, p = 0.01). Physical and/or sexual violence victimisation in the absence of other victimisation was not associated with HIV (aPR: 0.92, 95%CI:0.73–1.15, p = 0.46). IPV and HIV interventions are incomplete without addressing emotional and controlling IPV and the role of coercive relationship dynamics in transmission risk.

Vaginal douching in Zambia: a risk or benefit to women in the fight against cervical cancer: a retrospective cohort study

BackgroundCervical cancer was the most commonly diagnosed cancer and the leading cause of cancer related deaths in 2013 among women in Zambia. We determined factors associated with vaginal douching with any solution other than water and examined its role as a risk factor for abnormal cervical lesions among Zambian women.MethodsWe conducted a retrospective cohort study using data from the Cervical Cancer Prevention Program in Zambia among 11,853 women (15 years or older) who had screened for cervical cancer from 6 provinces of Zambia. Stata version 15 was used to analyze the data. Investigator led stepwise logistic regression was used to estimate adjusted odds ratios and 95% confidence intervals for various characteristics, with vaginal douching with any solution as primary outcome and abnormal cervical lesions as secondary outcome.ResultsDouching with any solution other than water was practiced by 8.1% (n = 960) of the study participants. Older women (35–44 and 45 years or older) vs young women (15–24 years old) were less likely to douche with a solution (AOR 0.74; 95% CI: 0.57–0.97, p = 0.027 and AOR 0.65; 95% CI: 0.49–0.87, P = 0.004), respectively, and so were women in informal employment compared to housewives (AOR 0.72; 95% CI: 0.58–0.89, p = 0.002). Odds of douching were higher among women with secondary vs. no formal education (AOR 1.64; 95% CI: 1.15–2.35, P = 0.007), and among women who used condoms sometimes compared to those who never with their regular sexual partners (AOR 1.19; 95% CI: 1.01–1.40, PP = 0.037). About 12.2% of study participants had abnormal cervical lesions. The use of either vinegar, ginger, lemon, salt or sugar solution was associated with increased risk of abnormal cervical lesions (AOR 7.37; 95% CI: 1.43–38.00, p = 0.017) compared to using water.ConclusionWe find an association between douching with a solution and a woman’s age, educational attainment, occupation and condom use. Vaginal douching with either vinegar, ginger, lemon, salt or sugar solution was associated with increased risk for abnormal cervical lesions. We recommend further research on ever vs never douching and the risk for abnormal cervical lesions.

422. Pooling Strategy for Chlamydia trachomatis and Neisseria gonorrhoeae Reduces Cost of GeneXpert Molecular STI Screening in Two Limited-Resource Clinics in Zambia

BackgroundRisk of heterosexual HIV-1 transmission is elevated in the presence of sexually transmitted infections (STIs) such as chlamydia (CT) and gonorrhea (NG). Syndromic management is a common, low-resource, approach to detecting STIs. However, CT and/or NG infections in women are often asymptomatic and therefore missed by syndromic management. Molecular testing for STIs is highly sensitive, but time and cost restraints preclude implementation of these technologies in resource-limited settings. Pooling samples for testing together in GeneXpert cartridges is one strategy for reducing the cost per individual tested.MethodsThis project describes the development of a pooling strategy based on social and demographic factors associated with CT/NG prevalence rates in a cohort of high-risk women in Zambia. Logistic regression modeling was used to predict the probability of a positive CT/NG test result in the presence of various factors. Data from a 2016 cross-sectional sub-study on intra-vaginal practices in 509 women was examined and an easy-to-use diagnostic screening checklist was created to categorize women by probability of testing positive on the GeneXpert. An algorithm considering cost of each test and prevalence of disease in each group determined the optimal pool size for each risk category.ResultsLogistic regression identified CT/NG to be associated with: city, age, education, long-acting reversible contraception usage, and laboratory results for bacterial vaginosis, Trichomonas vaginalis, and incident syphilis on the day of CT/NG testing. Signs and symptoms were not found to be associated. The overall prevalence of either CT and/or NG infection in this population was 17%. Low, middle, and high-risk groups could be separated based on checklist score with 7.52%, 18.30%, and 46.51% CT/NG prevalence, respectively.ConclusionPooling women with similar CT/NG predictive factors together, or testing those at highest risk individually, reduces the cost per test. Further implementation of this tool to guide presumptive treatment, in lieu of molecular testing, increases the cost-saving potential. The strategies described in this study are applicable to other low-resource clinical settings seeking to provide the accuracy of molecular testing with a reduced financial burden.Disclosures All authors: No reported disclosures.

Effect of Enhanced Adherence Package on Early Retention in Care Among HIV-Positive Pregnant Women in Zambia: An Individual Randomized Controlled Trial

Background: Suboptimal retention may undermine the individual and public health benefits of immediate lifelong antiretroviral therapy (ART) for HIV-positive pregnant women (i.e., Option B+). We evaluated the effect of an intervention called the B-plus Enhanced Adherence Package (BEAP) on early ART uptake and short-term retention among newly diagnosed HIV-positive pregnant women in Lusaka, Zambia. Methods: Pregnant women at 3 public sector facilities in Lusaka urban district who were 18+ years old, HIV-positive, and ART naA¯ve were enrolled between March 02, 2017 and December 18, 2017 and randomized 1:1 to BEAP versus standard of care (SOC) services. All participants were eligible for Option B+ per national guidelines. BEAP involved early (within 1-2 weeks of eligibility for option B+) phone calls and home visits from a male-female pair of community health workers (CHW) to provide additional counseling, engage male partners in HIV testing, and follow-up any missed ART appointments. CHW documented all BEAP activities. The primary outcome, initiation and retention on ART per pharmacy records at 30 days after Option B+ eligibility, was compared by study arm in an intention to treat (ITT) analysis using logistic regression. In a per protocol analysis we also assessed the impact of BEAP on initiation and retention among those women who were confirmed to have received BEAP services. In pre-planned subgroup analyses, we also evaluated the BEAP's impact according to participant age, parity, baseline HIV partner disclosure status and baseline CD4+ count. Findings: Among 454 women enrolled, 229 were randomized to BEAP and 225 to SOC. The two arms were balanced with respect to age (p=0.16) and gestational age (p=0.09). Within 30 days of Option B+ eligibility, 445 (98.2%) initiated ART; however, only 369 (82.9%) of those women who started ART were still in care at 30 days. In ITT analysis, the proportion initiating and remaining on ART at 30 days was similar between women randomized to BEAP versus SOC (82.5% versus 80.4%; crude relative risk [RR], 1.03; 95% confidence interval [CI], 0.91-1.16). After exclusion of 92 participants (40.2%) due to not receiving BEAP services based on CHW documentation and 1 participant due to ineligibility, BEAP was associated with being on ART at 30 days versus SOC (91.9.0% versus 80.4%; crude RR 1.14; 95% CI, 1.02-1.29). No significant variation was found in the effect of BEAP in subgroup analyses based on parity, age, baseline HIV disclosure status, and/or baseline CD4+ count. Interpretation: Uptake of Option B+ within 30 days of eligibility was nearly universal among HIV-positive pregnant women in urban Zambia. Women who received the BEAP intervention were statistically more likely to be on ART at 30 days compared to those receiving standard services. This difference, though modest, supports the potential of targeted early interventions to optimize the implementation of Option B+. Trial Registration: The trial was also registered at ClinicalTrials.gov (trials number NCT02459678).

Integrated Care Delivery for HIV Prevention and Treatment in Adolescent Girls and Young Women in Zambia: Protocol for a Cluster-Randomized Controlled Trial.

BackgroundAmong countries in sub-Saharan Africa, Zambia has one of the highest incidences of HIV. Adolescent girls and young women (AGYW) are a particularly affected group because of their social and economic vulnerability.ObjectiveThe goal of this study is to test a multilevel package of interventions at the community and health system levels in Zambia in order to connect AGYW with a source of regular care, which will in turn allow for sustainable, successful implementation of regular HIV testing and adherence to antiretroviral treatment.MethodsWe will adapt prior tools to create the SHIELD (Support for HIV Integrated Education, Linkages to Care, and Destigmatization) intervention to educate and empower Zambian AGYW of 10-24 years of age and their families and to create community-based youth clubs to foster peer support. We will also develop integrated wellness care clinics to offer a youth-friendly environment that provides tailored clinical services. We will perform formative research, including focus groups and in-depth interviews, among AGYW, caregivers, and stakeholders to help inform the development and tailoring of the interventions. A cluster-randomized controlled trial will be implemented in Lusaka, with six clinic catchment areas randomized into three groups: zones with integrated wellness care clinics and SHIELD intervention, zones with only SHIELD intervention, and control zones with no intervention. We will assess HIV testing among the HIV-negative or unknown (HIV-/u) cohort, and retention in care along with viral load suppression will be evaluated in the HIV-positive (HIV+) cohort. We will use in-depth interviews and surveys to collect staff and stakeholder feedback after the trial. Cost-effectiveness of the interventions and return-on-investment impacts will be quantified using a microsimulation model.ResultsInterim results are expected in 2021, and the final results are expected in 2022. If this multilevel intervention is successful in establishing a comprehensive care continuum for HIV-affected AGYW, the Zambian Ministry of Health may advocate for expansion to additional settings to support national scale-up.ConclusionsThis integrated service delivery model can also be a platform to implement additional preventive services, so HIV-/u and HIV+ AGYW can receive comprehensive, integrated services.Trial RegistrationClinicalTrials.gov NCT03995953; https://clinicaltrials.gov/ct2/show/NCT03995953 International Registered Report Identifier (IRRID)PRR1-10.2196/15314

Hygiene practices of mothers of hospitalized neonates at a tertiary care neonatal intensive care unit in Zambia

AbstractRisk of neonatal mortality secondary to infections such as pneumonia and diarrhoeal diseases can be influenced by maternal hygiene, but little information is known about current maternal hygiene practices in low- and middle-income countries. This study aimed to assess the hygiene practices of mothers of neonatal intensive care unit (NICU) patients in Lusaka, Zambia and associated epidemiological factors. A cross-sectional survey of the mothers of hospitalized neonates at the University Teaching Hospital (UTH) in Lusaka was conducted. Study nurses orally administered questionnaires to mothers in their local languages about their hygiene practices related to newborn care. Of the 201 mothers surveyed, self-reported hygiene practice was associated with literacy (p = 0.013) and income (p &amp;lt; 0.0001). In contrast, adherence to recommended hygienic newborn care was less common, with only 36% of mothers practising recommended cord care practices. Forgetfulness (32%) and lack of hygiene resources (13%) were the major barriers to hygienic behaviours. Surveyed Zambian women who delivered babies requiring NICU care self-reported adequate hygienic practices and apparently faced difficulty practising them due to forgetfulness and a lack of hygiene resources. Future efforts should focus on improving cord care education, reinforcement of the importance of hygienic behaviours, and the supply of affordable antiseptic tools.

Highly diverse anaerobe-predominant vaginal microbiota among HIV-infected pregnant women in Zambia.

Vaginal dysbiosis has been shown to increase the risk of some adverse birth outcomes. HIV infection may be associated with shifts in the vaginal microbiome. We characterized microbial communities in vaginal swabs collected between 16–20 gestational weeks in the Zambian Preterm Birth Prevention Study to investigate whether HIV and its treatment alter the microbiome in pregnancy. We quantified relative abundance and diversity of bacterial taxa by whole-genome shotgun sequencing and identified community state types (CST) by hierarchical clustering. Associations between exposures—HIV serostatus (HIV+ vs HIV-) and preconceptional ART (ART+ vs ART-)—and microbiome characteristics were tested with rank-sum, and by linear and logistic regression, accounting for sampling by inverse-probability weighting. Of 261 vaginal swabs, 256 (98%) had evaluable sequences; 98 (38%) were from HIV+ participants, 55 (56%) of whom had preconceptional ART exposure. Major CSTs were dominated by: L. crispatus (CST 1; 17%), L.] iners (CST 3; 32%), Gardnerella vaginalis (CST 4-I; 37%), G. vaginalis & Atopobium vaginae (CST 4-II; 5%), and other mixed anaerobes (CST 4-III; 9%). G. vaginalis was present in 95%; mean relative abundance was higher in HIV+ (0.46±0.29) compared to HIV- participants (0.35±0.33; rank-sum p = .01). Shannon diversity was higher in HIV+/ART+ (coeff 0.17; 95%CI (0.01,0.33), p = .04) and HIV+/ART- (coeff 0.37; 95%CI (0.19,0.55), p < .001) participants compared to HIV-. Anaerobe-dominant CSTs were more prevalent in HIV+/ART+ (63%, AOR 3.11; 95%CI: 1.48,6.55, p = .003) and HIV+/ART- (85%, AOR 7.59; 95%CI (2.80,20.6), p < .001) compared to HIV- (45%). Restricting the comparison to 111 women in either CST 3 (L. iners dominance) or CST 1 (L. crispatus dominance), CST 3 frequency was similar in HIV- (63%) and HIV+/ART- participants (67%, AOR 1.31; 95%CI: (0.25,6.90), p = .7), but higher in HIV+/ART+ (89%, AOR 6.44; 95%CI: (1.12,37.0), p = .04). Pregnant women in Zambia, particularly those with HIV, had diverse anaerobe-dominant vaginal microbiota.

Increase in Obesity Among Women of Reproductive Age in Zambia, 2002-2014.

Objective: To describe trends in obesity in Zambian women of reproductive age and to identify factors that may have contributed to changes in trends and nutrition outcomes. Materials and Methods: We obtained data on body mass index and individual factors of women from the Zambia Demographic and Health Survey for the period 2002 to 2014. From these data, we calculated descriptive statistics and examined the extent to which factors link to the odds of obesity over time. We also reviewed primary and secondary data sources, such as government documents, theses, and search engines to identify factors that may have contributed to trends and changes in nutrition outcomes. Results: The proportion of obesity doubled from 2002 (12.5%) to 2014 (22.3%). The odds were higher among educated, currently married and wealthy women, and it increased with age. Rural residence and working in agricultural-related jobs were linked to lower odds for obesity. This disparity varies by province. In addition, despite the presence of many nutrition policies and strategies, the increase in obesity occurred within the past two decades when urbanization and other factors (e.g., sedentary work, a proliferation of fast food restaurants, and advertisements) may have affected changes in nutrition outcomes for women. Conclusions: We identified increasing trends in obesity in women of reproductive age over time. The rapid urbanization and other factors that occurred in Zambia during this period are significant risk factors for obesity in Zambian women. The findings will be of interest to countries that are undergoing a nutrition transition.

Out-of-pocket expenditure for home and facility-based delivery among rural women in Zambia: a mixed-methods, cross-sectional study.

PurposeOut-of-pocket expenses associated with facility-based deliveries are a well-known barrier to health care access. However, there is extremely limited contemporary information on delivery-related household out-of-pocket expenditure in sub-Saharan Africa. We assess the financial burden of delivery for the most remote Zambian women and compare differences between delivery locations (primary health center, hospital, or home).MethodsWe conducted household surveys and in-depth interviews among randomly selected remote Zambian women who delivered a baby within the last 13 months. Women reported expenditures for their most-recent delivery for delivery supplies, transportation, and baby clothes, among others. Expenditures were converted to US dollars for analysis.ResultsOf 2280 women sampled, 2223 (97.5%) reported spending money on their delivery. Nearly all respondents in the sample (95.9%) spent money on baby clothes/blanket, while over 80% purchased delivery supplies such as disinfectant or cord clamps, and a third spent on transportation. Women reported spending a mean of USD28.76 on their delivery, with baby clothes/blanket (USD21.46) being the main expenditure and delivery supplies (USD3.81) making up much of the remainder. Compared to women who delivered at home, women who delivered at a primary health center spent nearly USD4 (p<0.001) more for their delivery, while women who delivered at a level 1 or level 2 hospital spent over USD7.50 (p<0.001) more for delivery.ConclusionThese expenses account for approximately one third of the monthly household income of the poorest Zambian households. While the abolition of user fees has reduced the direct costs of delivering at a health facility for the poorest members of society, remote Zambian women still face high out-of-pocket expenses in the form of delivery supplies that facilities should provide as well as unofficial policies/norms requiring women to bring new baby clothes/blanket to a facility-based delivery. Future programs that target these expenses may increase access to facility-based delivery.

Knowledge, attitudes and practices of cervical cancer prevention among Zambian women and men

BackgroundIn Zambia, cervical cancer screening was started in 2006 and the human papillomavirus vaccine was piloted in 2013. Nevertheless, cervical cancer remains the leading cancer. It is assumed that knowledge, social interaction, health behaviors and religion are factors that can influence screening and vaccination practices. This study addresses the question, what is the relationship between knowledge about cervical cancer, attitudes, self-reported behavior, and immediate support system, towards screening and vaccination of cervical cancer of Zambian women and men. The results of this study serve as a basis for future research, an input for improvement and adjustment of the existing prevention program and build on documented health behavior frameworks.MethodsA cross-sectional mixed methods study was conducted from February to May 2016. Two separate questionnaires were used to collect data from women (N = 300) and men (N = 300) residing in Chilenje and Kanyama (two townships in the capital city Lusaka). Respondent’s knowledge of cervical cancer was operationalized by grading their ability to correctly identify causes and protective factors if they were aware of cervical cancer. Besides providing descriptive statistics of all study variables, we tested four research hypotheses concerning the link between knowledge, attitudes and practices suggested by the literature, by applying appropriate statistical tests (chi square test, analysis of variance, logistic regression).ResultsLess than half of the respondents (36.8%) had heard of cervical cancer, 20.7% of women had attended screening and 6.7% of the total sample had vaccinated their daughter. Knowledge of causes and prevention was very low. There was a strong association between having awareness of cervical cancer and practicing screening (odds ratio = 20.5, 95% confidence interval = [9.214, 45.516]) and vaccination (odds ratio = 5.1, 95% confidence interval = [2.473, 10.423]). Social interactions were also found to greatly influence screening and vaccination behaviors.ConclusionsThe low level of knowledge of causes and prevention of cervical cancer suggests a need to increase knowledge and awareness among both women and men. Interpersonal interactions have great impact on practicing prevention behaviors, for instance, vaccination of daughters.

Multiple-Strain Infections of Human Cytomegalovirus With High Genomic Diversity Are Common in Breast Milk From Human Immunodeficiency Virus-Infected Women in Zambia.

BackgroundIn developed countries, human cytomegalovirus (HCMV) is a major pathogen in congenitally infected and immunocompromised individuals, where multiple-strain infection appears linked to disease severity. The situation is less documented in developing countries. In Zambia, breast milk is a key route for transmitting HCMV and carries higher viral loads in human immunodeficiency virus (HIV)–infected women. We investigated HCMV strain diversity.MethodsHigh-throughput sequence datasets were generated from 28 HCMV-positive breast milk samples donated by 22 mothers (15 HIV-infected and 7 HIV-negative) at 4–16 weeks postpartum, then analyzed by genome assembly and novel motif-based genotyping in 12 hypervariable HCMV genes.ResultsAmong the 20 samples from 14 donors (13 HIV-infected and one HIV-negative) who yielded data meeting quality thresholds, 89 of the possible 109 genotypes were detected, and multiple-strain infections involving up to 5 strains per person were apparent in 9 HIV-infected women. Strain diversity was extensive among individuals but conserved compartmentally and longitudinally within them. Genotypic linkage was maintained within hypervariable UL73/UL74 and RL12/RL13/UL1 loci for virus entry and immunomodulation, but not between genes more distant from each other.ConclusionsBreast milk from HIV-infected women contains multiple HCMV strains of high genotypic complexity and thus constitutes a major source for transmitting viral diversity.

Factors associated with choice of antenatal, delivery and postnatal services between HIV positive and HIV negative women in Zambia

BackgroundPrevious research has shown that developing countries account for the majority of maternal deaths around the world. Relatively high maternal mortality in developing countries has been linked to high HIV prevalence rates in these countries. Several studies have shown that women living with HIV are more vulnerable and are thus more likely to die during maternity than those who are not. Although there has been increased focus on this subject in contemporary research, the relationship between HIV status and maternal-care-utilization is not very well understood. It is not clear whether factors associated with professional maternal care utilization during antenatal, delivery and postnatal periods are similar for HIV positive and HIV negative women. It is also not known whether being HIV positive has an impact on the choice of care (professional care or traditional birth attendants). Thus the aim of this study is to investigate the differences in factors affecting choice of care during antenatal, delivery and postnatal periods between HIV positive and HIV negative women. We also investigate the effect of HIV positive status on choice of care.MethodsBy using the 2013–2014 Zambia Demographic Health Survey Data (ZDHS), we performed two different quantitative analyses. a) Regression analysis: to identify and compare factors associated with the likelihood of utilizing professional care during antenatal, at birth and postnatal periods between HIV positive and HIV negative women. b) Propensity score matching: to investigate the effect of being HIV positive on the choice of care (Professional care or TBAs).ResultsOur results show that reasons for choosing professional care during antenatal, at birth, and postnatal periods are the same for both HIV positive and HIV negative women. Further, we also showed that although the probability of utilizing professional care is slightly higher for HIV positive women, the difference is negligible.ConclusionWe demonstrated that in Zambia, utilization of professional care among HIV positive women is not particularly high. We also demonstrate that although institutional care is desirable and an ideal solution for HIV positive women, insisting on institutional care when the health facilities lack adequate trained personnel, drugs, and equipment is counterproductive.

Inflammatory and Nutritional Biomarkers in the Plasma of Women in Zambia Reflect Low DHA and HIV Status

Docosahexanenoic Acid (DHA) is a fatty acid that is abundant in the brain, retina, and cerebral cortex. It is critical in fetal brain development and is implicated in resolution of inflammation. In recent years, there has been a growing concern that low dietary levels of DHA in pregnancy may lead to poor birth outcomes and delayed or reduced cognitive function in children after birth. Uncontrolled HIV infection may lead to cognitive impairments as well as reduced immune function. Therefore, for pregnant women living with food insecurity and HIV infection, these problems may be compounded and health risks to their infants high. To evaluate these concerns, a pre‐clinical trial was conducted in pregnant women in Zambia, a country where malnutrition and HIV are endemic. The study participants included 91 women in the second trimester of pregnancy, 46 of which were HIV seropositive and 45 HIV seronegative. Among the HIV positive participants 11 had high viral load. The overarching study goal was to determine if plasma DHA levels were low relative to global averages and if they correlated with inflammation and HIV status. Hematological assessment included measurement of biomarkers for nutritional status, HIV status and viral load, as well as inflammation. Plasma lipids were assessed using the Folch extraction method, fatty acid methyl esters were prepared and analyzed by gas chromatography/mass spectrometry. Protein biomarkers data were measured using commercial ELISA kits. Overall, DHA levels were low at 2.16±0.75 mass percent of total fatty acids but did not vary significantly with HIV status. Averages of the nutritional biomarkers insulin and leptin were low and high, respectively, compared to global averages when comparing all participants. Insulin was not significantly different based on HIV status. Leptin was reduced in HIV seropositive participants compared to those who were seronegative and this correlated, as expected, with pre‐pregnancy BMI. For the inflammatory markers CRP and LCN2, only LCN2 was significantly different dependent on HIV status, and levels were on average lower in seropositive individuals. Within the HIV positive participants, the 11 with high vial load did not have levels of insulin, leptin, CRP or LCN2 that were significantly different from those with low viral load. These data demonstrate that select protein biomarkers for inflammation and nutrition are variably affected by HIV and nutritional status. Currently, these studies are being expanded to understand the role of dietary fatty acids in contributing to health outcomes in pregnancy and dependent upon HIV status.This abstract is from the Experimental Biology 2019 Meeting.

Evaluation of n‐3 fatty acid status of pregnant women in Zambia with relation to HIV infection

Malnutrition and human immunodeficiency virus (HIV) are independent risk factors for impairment of fetal and early childhood development, altered brain structure, and reduced cognitive function. Docosahexaenoic acid (DHA (C22:6cisΔ 4,7,10,13,16,19 ω3)) is a fatty acid that is abundant in the brain, retina, and cerebral cortex. Additionally, DHA‐derived eicosanoids function in the resolution of inflammation. Thus, there it is hypothesized to be a link between DHA status, brain function and inflammation that may be critical in HIV positive pregnant women. Brain development and DHA incorporation into neuronal tissues occur largely during the last trimester of pregnancy to 24 months after birth. DHA may be acquired either through de novo synthesis from linolenic acid (LN (C18:3 cisΔ 9,12,15 ω3)) or from the diet. The present study was undertaken to evaluate DHA status in terms of dietary intake and plasma levels in pregnant women in Zambia, a country where food insecurity and HIV infection are highly prevalent. Initially, 113 women were enrolled in this study at the antenatal clinic of the Women and Children's Hospital in Lusaka, Zambia. The participants completed a health and dietary questionnaire and then a fasting blood sample was acquired. Ultimately, 45 HIV seronegative and 46 HIV seropositive women were included in the study cohort. Pre‐pregnancy BMI had a mean of 22 and ranged from 17.9 to 24.9, thus none of the women were clinically underweight. Gestational age ranged from 20–29 weeks with an average of 22. Blood lipids were measured to quantitate and compare triglyceride, lipoprotein and total cholesterol, and fatty acid levels. Total fatty acid profiles were assessed using gas chromatography/mass spectrometry (GC/MS). Essentially all participants reported eating fish on a regular basis averaging 2‐times per week and most (80%) consumed the small sardine‐like fresh water fish Kapenta, that is known to be relatively high in DHA. However, plasma fatty acid profiles indicated a high ω6 to ω3 ratio and low LN, EPA and DHA levels overall. There were no significant differences in these values between HIV seropositive and seronegative participants. Therefore, we propose DHA supplementation is warranted to raise blood DHA levels during pregnancy in Zambia to address both child development and the mother's health.Support or Funding InformationWorld Health Organization (WHO)Undergraduate Creative Activities and Research Experience (UCARE)This abstract is from the Experimental Biology 2019 Meeting.
